Ghost Hawk by Susan Cooper Essay - 1472 Words

Synopsis Ghost Hawk is about the experiences of two young men named Little Hawk and John Wakeley, who grow up in different environments yet are trapped in the same conflict between the Englishmen and the Indians in the American Indian Wars. Plot Summary The story began when a Indian man took out a tomahawk blade and twisted two slim branches from a small bitternut hickory tree on a salt marsh around the blade. Eleven years later, the same man chopped down the same tree and gave the finished tomahawk to his son, Little Hawk. He informed him that he was going to go through a ritual that required him to survive three months in the woods alone. When he returns, Little Hawk will finally prove himself as a man. The tomahawk is one of the things†¦show more content†¦John just stood in shock. Two Englishmen came out the trees, one was named Daniel Smith and the other was named Walter Kelly. They had thought Little Hawk was attacking John so they killed him. They threw Little Hawk’s body aside, and started hacking at the branch to free John’s father. John began to cry and shrieked at the men, saying that Little Hawk was just trying to help. John started to grow a sense of hatred towards the two Englishmen. People carried John’s father away in a litter and nobody noticed John taking Little Hawk’s tomahawk and sliding it under his jacket. That night, John’s father died. Soon after, Daniel Smith married John’s mother. One year later, Daniel sent John away to be an apprentice to a cooper named Master Medlycott. On the way, he met a pretty girl named Huldah Bates who was going to live with the Kelly household and help the mistress there. When John arrived to the Medlycott household, Master Medlycott greeted him and gave him tasks to do. The schedule was same every week. On Sundays, John and the Medlycotts went to the meetinghouse for a sermon. John rarely had the chance to speak to Huldah Bates but they exchanged smiles in the meetinghouse. One Sunday, a preacher named Roger Williams arrived at the meetinghouse and talked about freedom of religion and stated that everyone are all brothers and sisters, including the Indians.

The Iroquois Vonda Matthews Cultural Anthropology July 7, 2013 Instructor: Rebekah Zinser Kinship is the cornerstone for how people within a society relate to others and race lineages. Many societies trace their lineage through the father, which is called patrilineal, or through the mother which is called matrilineal. The Iroquois nation traced their kinship through the matrilineal decent lines. Kinship directly relates to how family groups think, act and live along side each other. The culture of the Iroquois can also be compared to how many American families relate to one another as well. Iroquois Lineage The Iroquois nation traced their lineage through the female sex; this is called the matrilineal line. Women of the†¦show more content†¦Often times there are couples that get married but have chosen not to stay with one another because of a difference in opinion, this is called divorce. Iroquois and divorce Often time’s couples marry only to find out that they have a difference of opinion or one spouse has caused serious marital strain on the other. Since the Iroquois couples lived matrilineally, this makes it easier for the woman to dissolve the marriage, keep her children and continue to live at home with her family. â€Å"If a woman no longer desired to be married to her husband, all she had to do was pack up her husband’s belongings and leave them on the steps of the longhouse. When he came home, the husband would find them, realize his wife had terminated the marriage, and return to his home village and his own patrilineage.† (Nowak, B. amp; Laird, P. 2010 chapter 4.5 Divorce) In the American culture it is more difficult to obtain a divorce. Americans and divorce Americans divorce for the same reasons the Iroquois divorced for however, in the American culture it is harder to divorce. Many times couples divorce because of infidelity of one or both of the spouses, or from irreconcilable differences. In order to obtain a divorce in America many states require the couple to attend counseling to see if they can fix their marriage. Sometimes this is successful and the couple will stay together and often times it is not possible for the couple to stay together so they will then obtain a divorceShow MoreRelatedThe Iroquois Creation Myth1190 Words   |  5 Pagescame to be before the Europeans entered North America.

string(85) " human resource and provides accurate  information  needed in an information system\." CHAPTER 1 1. The Problem and Its Background 2. 1 Introduction Enrollment serves as a vital part in the life of every student upon entering schools or universities, either public or in private. We will write a custom essay sample on Onhs Documentation or any similar topic only for you Order Now It gives students the impression on how the whole institute manages and manipulates the entire body. Moreover, enrollment serves as the first experience of all students by which he/she takes part either individually or with company of a parent or some relatives. Enrollment is considered as the first step or procedure that must be done by old students within a particular institution before the semester per school year totally starts, but for those freshmen, or first year students (new students), they are obliged to usually take an admission test, to know and assess them the right course to engage to, followed by a scheduled interview in order to give them brief instructions and information about certain issues with regards to the school’s policies, institutional programs as well as personal information, health, economic status, so on and so forth. Good enrollment is always an asset in a school, pertaining to fast payment, assessment procedures, and easy transactions with a high rate of accuracy. Therefore, good enrollment within the schools, if present, can be described as civilize, organize, accurate and professional. Enrollment has always been a difficult task, but it is more so today than ever before, where administrators uses the traditional way of filing records on a cabinet. Schools, like any other organization used to manage all sorts of data and information to ensure attainment of its goals and objectives. The emerging needs in most schools for accurate and relevant data and reliable information strengthen the Student Information System. As the population of the students goes up, it is becoming more complex. Data should be stored in safer places, and can be retrieved easily and fast when someone needs it. Administrator’s task has becoming more complex, there have been efforts to improve the effectiveness of problem solving and central to this are quantitative techniques and electronic devices such as computers. This study aims to come up with an enrollment system and grades management with short message service system for a high school which also includes information pertinent data such as name, year, section, etc. This system is design for the use of the staff to enable them to produce information required by different people. It will make the work of faculty and staff faster, easier and more comprehensive. The system will also store the data of the students. For the future researchers, this study could be used for their reference in having an enrollment system and grades management with SMS System if the future researchers would like to formulate a system such as this. 2. 2 The Background of the Study Orani National High School (ONHS) is located at Kawayan, Orani, Bataan, it was established through the Sangguniang Panlalawigan Resolution No. 41. ONHS campus started to operate three years before its House Bill No. 1425 was approved as Republic Act No. 8419 on November 27, 1997. ONHS is composed of (1864) one thousand eight hundred sixty four students. Five hundred forty (540) are first year, four hundred sixty three (463) are second year, four hundred thirty two (432) are third year and four hundred twenty nine (429) are seniors or graduating. The school has sixty six (66) teaching and non-teaching staff. Fifty three (53) teaching personnel are regular permanent and are nationally funded. Five are contractual, funded by the Provincial School Board of Bataan and the Local School Board of Orani. The non-teaching personnel is composed of three (3) Department Heads, one (1) Disbursing Officer who are regular and permanent and five (5) contractual support personnel funded by the Provincial School Board of Bataan and Local School Board of Orani. All teachers passed the Professional Board Examination for Teachers (PBET) and Licensure Examination for Teachers (LET) with Master of Arts in progress and are teaching their own major or field of specialization. The faculty, staff, students and parents of this school are caring people, who share one vision and one mission and who continuously strive to make ONHS a caring school system in Orani where every learner is Maka-Diyos, Maka-kalikasan, Maka-tao and Maka-Bansa; and make every student understand, do and enjoy what they have learned by being role models. Their enrollment is being done manually by the registrar and when the enrollment start the registrar will have a hard time to enroll the student in their current enrollment system, they found that using a manual process is hard to handle such as collection of records like storing, finding, sorting and securing of records particularly if this stored only in one room and in a limited space. It will be a big hassle for the registrar and the student when or if ever their going to get data or information. In this new system it will be easy for them to enroll and to get data or information from the registrar and also enable the registrar to easily produce information required by the different people in the school. 2. 3 Statement of the Problem 2. 4. 1 General Problem How to design, develop and implement an Enrollment and Grades Management with Short Message Service System for Orani National High School that would help the enrollment and grading process? 2. 4. 2 Specific Problems * Difficult data manipulation * The present way of enrollment and grading system is time consuming * There is no data retrieval of lost file There is no standard format when printing of grades * Difficult parental updates of the students * Security 2. 4 Objective of the Study 2. 5. 3 General Objective To be able to design, develop and implement an Enrollment and Grades Management with Short Message Service System for Orani National High School. 2. 5. 4 Specific Objective * To develop an information system that has the ability to manipulate data accurately. * To develop an information system that will lessen the workload, time, human resource and provides accurate  information  needed in an information system.

The proposed system will be having a standard printing format for the data. * To develop an information system that has parental updates. * For security purpose. 2. 5 Significance of the Study Due to the increasing students of Orani National High School, this study helped the school regarding their enrollment transactions. The proposed system aimed to benefit the school in their enrollment facilities such as maintaining the files, assessment of fees and especially the enrollment itself. The proposed system aimed to benefit the following: The School The main beneficiary of the study is Orani National High School. ONHS would be adapting the new innovation of technology through C# programming language that will make their work with optimum performance. The developed system will compensate the flaws and problems that the school is encountering. Registrar With regards to the registrar’s office the proposed system will help the school in maintaining the data of the students and the school will not use the manual data gathering. ONHS will just need to check the database for the records needed. Students The students will benefit by means of not having a hard time in falling in line and waiting for their turn to register. Proponents The proponents would also be a beneficiary of the study since the proponents would value the importance of enhancing their skills and work performance while grasping knowledge throughout the study. Future Researchers For the future researchers, this study could be used for their reference in having an enrollment system if the future researchers would like to formulate a system such as this. 2. 6 Scope and Limitation The system will have the following features: * File Management * Students Master List * Grades Management * Generation of Reports * Student’s records report * Student’s grades report * Enrollment Process SMS function * Security However, the system will have the following limitations: * Enrollment Reservation * The SMS function is only available only during class hours between 8:00 am to 5:00 pm. * The SMS function cannot be used if the prepaid kit doesn’t have enough loads to send information. 2. 7 Conceptual Framework ONHS Enrollment and Grades Manag ement with Short Message Service System Of Orani National High School ONHS Enrollment and Grades Management with Short Message Service System Of Orani National High School ONHS System Students Information Students Grades Announcements through SMS ONHS System Students Information Students Grades Announcements through SMS Students Information Users Information Students Grades Announcements through SMS Students Information Users Information Students Grades Announcements through SMS Output Output Input Input Process Process Figure 1. 1 Conceptual Frame Work 2. 8 Definition of Terms System- Any organized assembly of resources and procedures united and regulated by interaction or interdependence to accomplish a set of specific functions.

CHAPTER 2 2. 0Review of Related Literature and Studies This section presents the writing of different facts and principles conducted by the proponents during the research, which have relevant to the study. It involves quotation of the author of the books and reference materials that may serve as the basis for sorting out and solving some problems that may be encountered in the development of the proposed study. 2. 1 Foreign Literature This portion presents a review of several literatures that would be beneficial to the study summarized from previous writings, showing detailed facts asserted by few people and pioneer in the field of computer industry. On this element of study some reviews of the proponents and author’s passage in order to help the proponents to find ways in contact with the problem that have been encountered. Success of SMS The proposed system has an SMS function. An SMS is intended only for short messaging. It is limited but very convenient to use. Even if it’s limitation, The SMS industry or Telecommunication industry is one of the most successful business ventures in the world. This was proved in the book of Brian Retford and Jordan Schwartz entitled â€Å"How to Build an SMS Service†. â€Å"SMS, or Short Message Service, is rapidly emerging as a multibillion dollar a year industry. A leading research firm reports that consumer spending on mobile services represents a $140 billion opportunity worldwide, with person-to-person SMS making up half f that. Portio Research reported that there were 946 billion SMSs sent in 2006. Clearly, the medium has hit the mainstream. To support the first statement, there is also an article regarding about the success of the SMS which is entitled â€Å"Future of SMS† by Ronald J. de Lange, Executive Vice President, Global Product Sol utions, Tekelec. â€Å"SMS has been the most successful non-voice service for mobile operators in the history of telecommunications and, as such, has been a key revenue generator. Every year stories of the demise of this 160-character service are thick in the air, and every year SMS usage continues to grow as more uses are found for this once ignored service. The key to the success of SMS has been its simplicity, reach, price and reliability. All other messaging based applications launched since SMS have struggled to meet the lofty expectations set by the service and pale in comparison to its success. Industry-related reports point to a future in which SMS volumes and revenue will continue to grow on a global basis for at least the next three years. So what is going to drive this level of growth? In short, several trends will drive the continued expansion of the service. † The researcher believed that the existence of SMS is a big help in terms of convenient way of communication. Importance of Computers in the Business Today, our generation is considered as a computer age. There is no place in the world without Computers. Computers, Internet, Facebook are now considered part of our lives. Even in the school, Computers give us a lot of benefits especially in the business. Computers can provide a business a fast, reliable, systematized and organized way of giving services. This was proved in the research article of Alexis Writing entitled â€Å"What Are the Advantages of Computers in Business†. â€Å"Computers have tremendously improved the way businesses operate in their respective industries. Technology has advanced so remarkably that those who are not using computers in their business are at a major disadvantage against their competitors. In particular, there are several important advantages that computers can provide to small businesses. Organization Computers allow the application of different types of software that can help businesses keep track of their files, documents, schedules and deadlines. Computers also allow businesses to organize all of their information in a very accessible manner. The ability to store large amounts of data on a computer is convenient and inexpensive, and saves space. A computer’s ability to allow a company to organize its files efficiently leads to better time management and productivity. Self-Sufficiency Computers have made staff and companies more self-sufficient by allowing them to do tasks that previously had to be outsourced. For example, a company can now use office software to create their own training material. Desktop publishing software can be used to create marketing materials. Online tax and accounting programs allow companies to prepare their own taxes. This allows the dominant operations of a company to remain in-house and empowers the company to become more independent and less susceptible to errors committed by outside parties. Cost-Effective Emerging technology makes new tools and services more affordable and allows companies to save on their staff payroll and office equipment. Because computers allow work to be done faster and more efficiently, it is possible for a company to hire fewer staff. In addition, with networked and relatively inexpensive computers, companies can store data more easily, saving on the cost of outside file storage, and can avoid having to purchase as many copiers, fax machines, typewriters, and other such items that were used before computers became popular. Correspondingly, potentially profitable businesses can be started with a smaller overhead cost. Email capabilities decrease postage costs; software applications reduce the need for large accounting departments, while videoconferencing reduces the need for travel. All resources saved will trickle down to the consumers, who are then provided with much more affordable products and service. Speed Computers help speed up other business operations. The collecting of consumer feedback, ordering of raw materials, and inspection of products is made quicker through the use of computers, allowing companies to operate much faster and to produce better quality results. Sales Computers can help generate higher sales and profits for businesses via a company website. Many businesses now operate online and around the clock to allow customers from around the world to shop for their products and services. 2. 2 Foreign Studies Short Message Service || SMS SMS can be used for a variety of uses in conjunction with mobile prepay including notification of low balance and balance inquiry, short codes used in conjunction with prepaid roaming, and even SMS itself can be provided on a prepaid basis by the mobile network operator. When used in conjunction with the SIM To olkit, SMS can be used as the vehicle for a variety of secure transaction-oriented services such as mobile banking; news alerts, product alerts, updated sports information, job alerts, and SMS aided utility services and so on. According to the study AN SMS AND WEB-BASED TRAFFIC CASE MANAGEMENT SYSTEM IN BANGLADESH by Sangeet Saha, August 2006, â€Å"The Traffic Police can use this SMS to know the case information, vehicle information and driver information. When the traffic police want to know this information then they will just send an SMS to a particular number. Then they will receive an SMS which contains all the information that they want to know. Thus this will help the traffic police in many ways. They can easily gather information through an SMS. Their SMS system will work when the police send an SMS using this format than this SMS will go to the central database and run the query. After getting the result, server will return an SMS to the police about the information. If no result found that it will also return an SMS of no result. In this the SMS for traffic, the police will send only the car license number. And the result will contain it’s case number, offender’s name, date of off ence, date of presence to the station and the papers name that are captured. In the published thesis of Yu Loon Ng, SHORT MESSAGE SERVICE (SMS) SECURITY SOLUTION FOR MOBILE DEVICES, December 2006, â€Å"This thesis focuses on the security of Short Message Service (SMS) and the Global System for Mobile communication (GSM) network, and the use of encryption to protect SMS messages. A detailed study of the GSM network, the SMS protocol and various encryption schemes was conducted to understand the properties of different encryption schemes and their applicability to SMS messages. An experiment was conducted to measure the actual performance of various encryption schemes on a modern smart phone. An analysis of the encryption scheme properties and the performance measurement was then conducted to select a suitable scheme for SMS encryption. The selected scheme was implemented in the form of a Secure SMS Chat application to validate the viability of the selected encryption scheme. Potential applications of secure SMS in military settings are also discussed. † Their thesis focuses on the use of encryption to secure SMS messages. The encryption requirements of voice traffic and other data traffic will not be discussed. The characteristics of different encryption schemes and their performance on a modern mobile device are presented. The properties of SMS were assessed with respect to their impact on encryption selection. Based on the measurement results, a suitable encryption scheme for SMS is selected, and deployed. A typical application is used to validate the selection. 2. 3 Local Studies Enrollment System The proponents primarily choose the topic regarding about enrollment is because this will give a lot of benefits to many, most especially to the students, teachers and of course the school. The other reason is because it has abundant resources that can help the proponents on developing the project. To improve the existing enrollment system our proposed system will be using the most efficient, fast and reliable machine that is widely used around the world which is computers. In the unpublished thesis of Computer Based Enrollment Information System for St. Mary’s College of Meycauayan by Joseph Bernard Reyes, May 2002 it is mentioned that â€Å"One cannot deny the fact that the computer has become a tool that is shaping almost every facet of life. It is used by the government, military, big businesses, in homes and of course in schools. This is especially true in highly industrialized countries like United States, Japan and England. Moreover, the expanding application of computers in education and in business organization has prompted leaders and managers to find ways on how to use the computer to make their operations more efficient. They are be used to enhance performance and efficiency and this makes them very valuable tools for most learning institution in the Philippines†. The existing enrollment system of the school ONHS is using manual filing system. Nowadays almost all Universities, Colleges and Private Schools are using Computerized Enrollment System, that’s why the respondents agreed that it is time for the school to change and upgrade their enrollment system. Enrollment is considered as the first step or procedure that must be done by the students within a particular institute. It gives students the impression on how the whole institute manages and manipulates the entire body. Moreover, enrollment serves as the first experience of all students by which he/she takes part either individually or with company of a parent or some relatives. According to the study of Computer Based Enrollment Information System for St. Mary’s College of Meycauayon, â€Å"Enrollment is the start of the relationship between the school and the students. Enrollment is one of the most important functions in any learning institution because it is the actual start of the interaction between the school and the students. † Moreover our proposed system aims to improve the Enrollment system of the school. The proponents want to help not only the students, teachers, the school but of course the development of the technology in our country. Short Message Service The proposed system offers not only Enrollment and Grading System but also an SMS or Short Message Service capability as well. The reason why the proponents came up on adding an SMS feature on the system is because aside from the internet, SMS is the best way to communicate with other people. According to the study â€Å"Tri Sensor Microcontroller Based Intelligent Monitoring System w/ SMS Transmission and Reception† by De Vera, Joy S. , Malixi, Jaime Jr. , Palisoc Aira, Purugganan, Leah S. , and Sarinas, Angolito Salvodor, Aug 20 2003. SMS is a globally accepted wireless service that enables the alphanumeric messages between mobile subscribers and external system. It is characterized by out-of-bound packet delivery and low bandwidth message transfer, which results in a highly efficient means for transmitting short bursts of data. † The proponents will use the SMS to communicate with the parents or guardians of the students. The system’s SMS function will be the formal way of the school to communicate with the parents. According again to the study, â€Å"Communication is one important factor in life. It is the process of passing information of what is happening. Today, one medium we are currently incorporating is SMS / Text Messaging. In SMS messaging, information is sent effectively and fast. † The proponents therefor conclude that an SMS function on a system will be a big help on improving the current system of the School. Short Message Service, means of Communication Cellular Phones have been a world-wide craze today. It plays an important role in everyone’s life. It helps us communicate and to be in touch with our love ones. One reason why all of us consider cellular phone a necessity is because of its SMS or short message service. In the Philippines there are many Telecommunications Company are offering a lot of affordable texting/SMS offers. According to the Study Microcontroller based SMS Micro E-load Vending machine by Cu, Joshua C. and Uy, Jeckson T. , August, 2006. â€Å"Cellular  communication can help us locate and be in touch with another person in a remote location. Since the Philippines being a developing country 33% of our population is under poverty (Senate Economic Planning Office, 2005). Wireless Telecommunications Company offered prepaid loading option that is highly suitable in the Philippine setting. Subscribers purchase consumable credits for  their account in present denominations. † In the statement above, it only shows how the SMS is widely used in our country. SMS or texting is considered not only for fun, it is considered today as a necessity. CHAPTER 3 3. 0 Methodology 3. 1Research Design Tools 4. 1. 1 Data Gathering Techniques Used Every  data  to  be  gathered  has  a  proof  from  the  respondents. Proponents interact on different participants which works are related to the design proposal, to gather relevant data from them. Directress was the overall head of enrollment system of Orani National High School. She deals with student’s evaluation and also has a list of copy of students enrolled. By  interview  and  observations,  proponents  will  know  current processes regarding enrollment activities. On the other hand, registrar department manages master list of the students  (new,  transferee,  old). The  department  was  also  assign  in sectioning of the students. By the use of this information, proponents will gather data about sectioning. In addition to that, selected parents and students will be an important participant since they are the main beneficiary of the design proposal. With the aid of surveys and sets of questionnaires about enrollment procedures, proponents will know problems regarding existing Enrollment System. Sources of Information a. Interviews which were conducted on the person involved in the Enrollment system to have a better understanding on how the current system works. b. Communication letters which were used by the proponents for request for permission to implement the study with the approval of the school. c. Other Sources of information are school documents provided by the school which contains information. Instruments Used  in the Survey, Sample Questionnaires, Interview  Questions, Communication Letters The following personnel are vital to how the system operates in which the proponents have selected to ask questions about how the current system works. a.

In this  scheme,  proponents  ask  information  in  detailed  questions  regarding what they observed in actual to the school. They also adopt quantitative approach of  study which observed particularly in numbers. This will  give way to use the method where in data are manipulated by means of  getting only  sample that can represent a  whole. A  good  instance  is  an enrollment system wherein student’s population is much involved. By getting some portion in the population of students in every year level, they can achieve data by means of average answers. 4. 2 Instrument used in Study a.

Progress flows from the top to the bottom, like a waterfall. This model represents the software development life cycle using processes, input and output. Each process transforms an input to produce a new product as output.

The database used is MySQL due to its flexibility and open-source nature. Visual C# C# (pronounced â€Å"C sharp†) is a programming language that is designed for building a variety of applications that run on the . NET Framework. C# is simple, powerful, type-safe, and object-oriented. The many innovations in C# enable rapid application development while retaining the expressiveness and elegance of C-style languages. Visual C# is an implementation of the C# language  by Microsoft. Visual Studio supports Visual C#  with a full-featured code editor, compiler, project templates, designers, code wizards, a powerful and easy-to-use debugger, and other tools. The . NET Framework class library provides access to many operating system services and other useful, well-designed classes that speed up the development cycle significantly. MySQL The most popular Open Source SQL database management system, is developed, distributed, and supported by Oracle Corporation.

Based on the investigations conducted, the school uses the traditional manual enrollment system. Data and information were kept on a filing cabinet, which finds difficulty and time consuming in retrieving the documents when needed. Grades were also kept by the present teacher of the students, which has no assurance of safe keeping. It also takes a long time to process grades, lists of students, and correction of entries. During the first day of school, the student finds it hard to locate their names in a list posted on the doors of the classroom. Because of this, we are proposing the Enrollment and Grades Management with SMS System. This software has the ability to keep student’s records in a single database. This system can be the solution to some of the problems encountered by the school as defined previously. It is recommended to the school to provide a computer where we can install the system. And also, a committee which can be headed by some teacher must be organized to operate the system. This software can be acquired in a very minimal cost. Free seminars and trainings will be given to the person who will operate the system, and manuals will be provided. Some of the benefits that can be acquired in this system were: * easy correction of entries * effective and efficient production of data * grades can be kept in a database for future use * upon enrollment, students can immediately know their designated sections * will lessen the workloads of the teachers and staff * effective enrollment processing This proposed system is guaranteed to use, and will not be useless. Alternative solutions should be considered to make their enrollment system improved and progressive. 5. 2Conclusion Based on the observations that the team conducted during the interview, we found out that on the manual system that the school is presently using, information and records were not kept accordingly that causes lost of important papers and documents. The student’s Form-137 was kept by the present teacher of the student as well as birth certificate or baptismal certificate, which has no assurance of safety keeping. Another problem identified is when the entries of names in the student’s lists are not updated, where some are complaining when records are incorrect if someone needs the documents. One respondent said that lists of classes were not produced immediately upon the start of the school year, that’s why it takes 2 to 3 days to know what the student’s section. By gathering sufficient information through research, and interview the proponents were able to develop a system that would help Orani National High School for the enrollment process. The system also eased ONHS from the risks and errors that are involved with their existing system. The development of an enrollment system requires an understanding and an analysis of the existing system of the problems, requirements, and specifications that the school laid out. It also required ample amount of preparation that involves conducting interviews, obtaining necessary information through research, and coming up with a resolution for the requirements of the school. 5. 3Recommendation Because of the problems encountered by  Orani National High  School, we recommend to the administration to have an Enrollment system that is useful in many ways, and that is the computerized enrollment system. An Enrollment and Grades Management with Short Message Service System that has the ability to store students information, to compute grades fast and easy and that can easily be retrieved and printed when needed. This enrollment system also can be able to make corrections of entry easily and fast. Through this, we can be sure that all the information will be kept in a single database so that we can minimize some problems like loss of records. It is recommended to the  Orani National High  School that the detailed specification and implementation of the system would ensue as long as the administration approved the Enrollment and Grades Management with Short Message Service System. * Provide a computerized enrollment system that has the ability to track records, make corrections and that can generate data fast and effective. *   Provide a system that can secure all the information and record of the students. *   Provide software that will lessen the workloads of the teachers and the administration. * To have a system that can give the students a successful enrollment system.

Latino and Black Children are not Insured

Question: Why more Latino and Black children arent insured. Answer: The randomized study on the Washington post article posted by Erin Blakemore was about the reasons why many Latino and black children are not insured since platforms like Medicaid and the Childrens Health Insurance Program (CHIP) were established to ensure the poor Americans access quality and equitable health care (Pei, 2014). The study population involved 267 children whose parents were interviewed. It was carried out from 2011 to 2014 in Dallas over a span of three years (Blakemore, 2016). Data was collected through structured interviews and direct interrogation about the parents knowledge on whether their children were eligible for the insurance. Out of the total studied Latino and black parents, forty-nine percent did not know that their children are qualified for CHIP or Medicaid. Collectively, ninety-five percent of the children were previously insured before the onset of the Medicaid and CHIP. These parents had incomes that were higher, and the African American parents were likely to be more aware than their Latino counterparts at a percentage ratio of 57 to 47. The parents had their reasons for the less involvement in the health insurance platforms. For instance, 30% of the parents had lost the cover and never reapplied. 9% did not receive replies after application, 8 % missed some important paperwork, and 4% said the fathers were to cover (Blakemore, 2016). The study concluded that more than 50% of the African American and Latino parents in Dallas do not utilize the subsidized insurance systems and those who do give up on the way. The randomized design benefited the study by ensuring easy and straightforward analysis of the findings, flexibility by accommodating the small population, and the elimination of bias in scenarios where only accessible parents could be interviewed. Furthermore, the study population was identified in an open manner eliminating doubts among the readers and observer groups. Because of the randomized study, it was readily known that high-income parents did not use these insurance provisions. Moreover, it could be hard for other study designs to specifically note that the African American and Latino parents out of the entire American population were underusing CHIP and Medicaid (Blakemore, 2016).

Effect Of Sleep On Memory Essays - Sleep, Memory,

Effect Of Sleep On Memory Effect of Sleep on Memory This article is from The Journal of Experimental Psychology, and was written on an experiment performed by psychologist Bruce R. Ekstrand, from the University of Colorado. He experimented on the effects that sleep has on ones memory, after learning a particular bit of knowledge, in this case a certain list of twelve three-letter words. There were several different ways Ekstrand went about discovering whether sleep would facilitate memory or not. Out of the entire group of people who he experimented on, some of them were given nothing but a simple list to memorize, some were given a pro-active interfering list, and some were given a retroactive interfering list. For his core measurement method, he used a 3x2 factorial chart. In this factorial were the three types of interference learning he used- retroactive, pro-active, and no interference. The factorials two-part were the levels of sleep that those who were experimented on got either eight hours of sleep, or none. The participants would have to learn these certain lists and associations with the lists, and perhaps pro-active or retroactive learning if they were assigned to that particular group. Half of the participants, chosen at random, would then sleep in the laboratory for approximately eight hours before being awakened in the morning, being urged to fall asleep as soon as they could, and with the average time it takes on to fall asleep being taken into account. Those who had to stay awake would leave for eight hours and return. Both groups would assure that no rehearsing had been done, and they would then have to recall the lists and associations. In most of the rehearsals for testing, sleep proved to facilitate recall better than staying awake did. However, the facilitation was not incredibly significant. In some of the pro-active and retroactive cases, sleep did not actually facilitate memory at allboth sleeping and awake people tested equally. I chose this particular article because I wanted to use its results to my benefit. I am always looking for ways to better prepare myself for tests, and better strategies for studying, both to learn more at one time, and to cut down on my entire studying time. Furthermore, I absolutely love to sleep, so I was hoping I could use this article as an excuse to sleep more, or as my rationale for sleeping often, assuming that I would study and then go to sleep. Some other articles I browsed through did not seem as interesting as this one, and I figured since this article was both interesting and helpful to me specifically, I would choose this one to write about. I have to admit that this article was a bit hard to comprehend, and quite hard to follow. I did manage to eventually understand most of it, but some of it was just impossible to grasp. Some of the language and terms used in this article are ones that I would have no way of knowing yet, based on my knowledge from psychology class. The writer used many abbreviations and symbols for certain procedures and items involved in the experiment, which made his sentences hard to follow at times. However, from eventually being able to understand it all, this article proved to be useful to me. I will definitely try to study more in the future, and then get to sleep right afterward. As I mentioned earlier, I am always looking for ways to improve my study habits and knowledge acquired from studying, and this article helped me with this quest. As a result of my reading, I learned that there is a good chance that sleeping after studying something will help me to remember it. I learned that I may need to change my study habits a little, to give myself more time to sleep after studying! This article did relate to in class material. It related specifically to the chapter we studied on memory. I could better understand this article because I had learned about memory, mainly about pro-active and retroactive inhibition. I believe some of the chapter discussed certain ways of learning and remembering, and this article definitely pertained to that topic. Overall, I would

Comparision contrast essays

Comparision contrast essays The cougar population is rising every year in Oregon and the population is moving closer to urban areas. As a result, cougar attacks are increasing. Management of the cougar population has become a political issue that sparks many debates. It is not too often anyone ever sees a cougar but they are out there. We walk threw the woods not even thinking of these creatures, but they are thinking about us and watching us. Sometimes cougars are too interested in us and our domestic animals, and this usually ends up with an injury or even death. The Oregon Department of Fish and Wildlife (ODFW) is responsible for maintaining a plan to manage the cougar population in Oregon. By examining ODFWs figures we can see that the population is rising. Prior to 1994 the annual growth rate was estimated at four to five percent. In 1994 a new law came into effect. Oregon Administrative Rule (OAR) 635-067-004(5) was put into place to ban the use of dogs for hunting or pursuing cougar. After the ban, the growth rate increased to approximately eight to twelve percent per year. ODFW states that, increased observations, road kill incidents and increasing damage complaints indicate the statewide cougar population has increased substantially since 1980. The new law was put into effect after a campaign alleged that the use of hounds was too cruel. However, without the use of hounds hunting the cougar has become to difficult. According to statistics on ODFWs website, from 1970 to 1994 hunters had an average success rate of 42%. From 1995 to 2000 the rate was down to a five percent average. To find a cougar without a dog is like searching for a needle in a hay stack. You must have a dogs nose to pick up on the sent of a cougar, a humans nose will not do. Cougars can smell and hear an approaching human long before the human is aware of the presence of the cougar. As they approach the cougar it will continue to ...

Culture, Social Status and Identity in Viramontes' The Months and Essay

Culture, Social Status and Identity in Viramontes' The Months and Tan's Rules of the Game - Essay Example These stories are the same because they depict the cultural and social status of their characters, and the main protagonists want to mold identities that conflict with their society’s beliefs about womanhood, but they are different, because they discover dissimilar sanctuaries, where they can be, who they are, without being judged. These short stories are the same, because they portray the cultural and social status of the characters. The beliefs and practices of the protagonist in â€Å"The Moths† demonstrate that she comes from a conservative and patriarchal society. This society demands their women to be submissive and skilled in feminine tasks and values, such as crocheting. Her father, who she calls Apa, often gets angry with her, because she dislikes going to church. As part of their conservative and religious culture, they are expected to go to mass every Sundays, especially decent girls and women. But she does not does not like the church, because its â€Å"vas tness† makes her feel alone (Viramontes). Likewise, in â€Å"Rules of the Game,† Waverly’s Chinese is culture is very conservative, where hierarchies exist. On top of the family hierarchy are parents, who children will and should never disobey. When Waverly’s mother says this, she embodies the â€Å"strong wind† in her daughter’s life: â€Å"Strongest wind cannot be seen† (Tan). She cannot see her mother, who is always at her back, watching and commenting on her every move, not only in chess, but in real life. The social status of the characters is also evident in the settings of the story. The protagonist in â€Å"The Moths† lives in a place where superstitions are respected. Her grandmother mixes dried moth wings with Vicks to soothe her â€Å"bull hands† and shrink them back to normal size (Viramontes). Her grandmother also has stomach cancer, but they do not have money to pay for expensive therapies. Similarly, Waverl y lives in a poor community, although she is not aware that she is poor. They live on a â€Å"†¦two-bedroom flat that sat above a small Chinese bakery† (Tan). It signifies living in a cramped and controlled space, where Waverly cannot expect to express her freedoms. These stories are also the same, because the female protagonists challenge their cultures, in order to form their identities. The protagonist in â€Å"The Moths† does not believe in following cultural norms about womanhood. Instead of learning how to crochet, she learns how to plant with her grandmother. Her â€Å"bull hand† signifies that she does not fit with her society, because her personality, preferences, and beliefs oppose female stereotypes and Christian norms. When she smells the chile, she cries not only because of the chile’s spice on her eyes, but also because of herself. She is like a chile that hurts the feelings of her family, who wants her to be someone she is not. She is also compared to the â€Å"defiant† sun, because they both resist changing for others (Tan). When the sun meets the land during sunset, the union depicts that â€Å"endings† are windows to â€Å"rebirths† (Tan). But if she will be reborn, she will be the same pertinent and critical daughter that makes Apa angry and disappointed. Also, Waverly defies her culture, by becoming a great chess player and toppling every other man or boy she plays with. Moreover,

OOS-Deviation assignment detecting the presence of diethylene glycol Essay

OOS-Deviation assignment detecting the presence of diethylene glycol in toothpaste by thin layer chromotography - Essay Example Additionally, for detection purposes, you will require 6.7 mg/mL of developing the solvent of Potassium Permanganate Staining Solution. Centrifuge tube of 50mL polypropylene to sample a preparation of toothpaste with a weight of around 1.0g. To disperse the toothpaste, add 5mL of water and vortex for around 1 minute. Next is the addition of 5mL of acetonitrile to the mixture followed by vortex about 1 minute. Prior to collecting around 1mL of the supernatant, centrifuge the mixture until you obtain a crystal-clear solution. Make use of the 1.5mL micro test tubes by transferring 500L of the supernatant to it then add 1.0mL of methanol. Dilute 0.2mL of DEG to 0.5mL using methanol in order to achieve the standard reference preparation (Ahuja & Scypinski, 2011). Spread the 5L diluted test solution and the reference standard solution on a sheet and leave it to dry. To get commendable results, use chromatographic procedure spot. The next step is to put the sheet in a developing tank that has been prepared by balancing 100mL of developing a solvent for about 30minutes. Remove the solvent and permit it to dry in the air immediately the developing solution reaches the stopping line. When you submerge the dried sheet in potassium permanganate solution and then remove the sheet after around 5 seconds, yellows spots will start to appear on the background as the sheet begins to dry. The last spot to appear is DEG. The reading of DEG varies from 0.40%, 0.41% and 0.44% for OOS results and between 0.005% and 0.015% for OOS deviation. According Ahuja and Scypinski (2011), after the examination of the OOS results, the procedures on the discovery and occurrences of the OOS are

PERSPECTIVES ON EFFECTIVE LEADERSHIP BEHAVIOUR Case Study

PERSPECTIVES ON EFFECTIVE LEADERSHIP BEHAVIOUR - Case Study Example Though a questionnaire is an appropriate research tool to measure leadership behaviour and its impact on the organization, it does have limitations. These limitations include response bias, which involves stereotypes or favoritism shown toward the leader by the respondents that can distort results. There may also be social norms that exist within the organizational culture that have established a leader is effective even though such effective behaviours have not been observed personally by respondents. Therefore, the respondents may provide information within the questionnaire format that they believe will satisfy these social norms about the leader. There may even be problems with reliability with the research instrument, the questionnaire, that is not developed with questions that accurately measure what is intended to be understood. Causality is defined as a cause and effect phenomenon where situation x occurs as a direct result of activities stemming from situation y. When measur ing leadership, causality might be whether leadership behaviour x has a direct impact on employee motivation y. Consider the following: An organizational leader is using a questionnaire format to determine whether motivation is being negatively affected by improper leadership. Correlations are being sought in relation to the respondent information returned from the research tools.

Effect of Curcumin on Periodontis

Effect of Curcumin on Periodontis INTRODUCTION Periodontitis is a chronic inflammatory disease characterized by destruction of the soft and hard tissues supporting the tooth. This tissue destruction appears to result from complex interaction between the bacteria and the host’s immune and inflammatory system. The host immune response identifies these invading pathogens and tries to neutralize or kill these microorganisms. During this process the host response elaborates a variety of mediators such as pro-inflammatory mediators, cytokines and proteolytic enzymes such as matrix metalloproteinases (MMPs). It is now believed that the major component of the soft and hard tissue destruction seen in periodontitis occurs as a result of activation of these mediators.1 Thus this host response which is essentially protective by intent paradoxically can also result in tissue damage. Hence recent therapeutic efforts are now focusing on altering or modulating this host response. This lead to emergence of a new comprehensive treatment str ategy for periodontitis which involves Host modulatory therapy (HMT) which can be combined with traditional periodontal therapies.2 To date, there is one FDA approved, systemic therapy that is prescribed as a host response modifier in the treatment of periodontal disease and that is adjunctive subantimicrobial dose doxycycline (SDD), which down-regulates the activity of MMPs.3 These MMPs are considered to be primary proteinases involved in periodontal tissue destruction synthesized by a variety of infiltrating inflammatory cells (i.e. neutrophils and macrophages), resident cells and some bacteria. Numerous studies have substantiated the relationship between MMPs and periodontal diseases, with findings of significantly higher MMP-9 (neutrophil derived MMPs) levels in patients with periodontitis compared to healthy controls.4, 5 Doxycycline is the most potent tetracycline for inhibition of these MMPs.6 However long term tetracycline therapy has certain disadvantages, the most important being the development of microbial resistance to this drug.7 At present a health care system exists in India where different types of diseases are being treated by Ayurvedic method. Since ancient times Ayurvedic drugs are being used for the treatment of various diseases, including periodontal and other oral diseases.8 They are widely acclaimed for their minimal side-effects and cost-effectiveness. Use of herbal extracts in treating periodontal diseases does not produce side effects of tetracycline compounds as well as other synthetic drugs. Curcuma longa (Turmeric) is a widely used herb which is distributed throughout tropical and subtropical regions of the world and widely cultivated in India, China and Indonesia.9 It has also long been used in both Ayurvedic medicine and Chinese medicine as an anti-inflammatory agent.9 The active constituent in turmeric is Curcumin.9, 10 Curcumin is known to have an anti-inflammatory effect. Studies show that Curcumin limits the activity of two enzymes, lipoxygenase and cyclooxygenase-2 that are involved in promoting and maintaining inflammation.11, 12 Studies have also shown that Curcumin down-regulates the MMP-9 activity.13, 14 Thus it may have a potential role in the treatment of inflammatory periodontal disease. Its anti-inflammatory activity in periodontal diseases has not been extensively investigated. With this background, the study was conducted to evaluate the anti-inflammatory effect of Curcumin by its inhibitory effect on MMP-9 activity and compare the same with Doxycycline, which is known to have an anticollagenase activity. MATERIALS AND METHODS Subjects: A total of 30 sites from 30 subjects (males and females), above 35 yrs of age, diagnosed clinically as having Chronic Periodontitis with pocket depths ranging from 5-8mm were selected for the study. The patients had no history of pervious dental treatment, antibiotic or anti-inflammatory drug therapy for the past 6 months. Patients with any history of systemic diseases / conditions, pregnant patients and smokers were excluded from the study. An informed consent was obtained from the patients prior to their enrollment into the study, and the study has been independently reviewed and approved by the institutional ethical board. Post collection of samples, the patients who participated in this study received the standard treatment protocol for Chronic Periodontitis. Method of Collection of Samples: Gingival tissue samples were obtained under aseptic conditions after administration of local anesthesia from patients who were diagnosed with Chronic Periodontitis. Gingival tissue samples were obtained from sites with pocket depths ranging from 5-8mm. Immediately following excision, these tissue specimens were briefly washed under cold distilled water and blotted dry. Then the specimens were transferred into sterile plastic vials which contained Phosphate Buffer Solution (PBS), pH 7.2, that acted as the transport medium. Specimens were then immediately carried to the laboratory where they were stored at -80à ¯Ã¢â‚¬Å¡Ã‚ °C until use. IN-VITRO STUDY Chemicals Used: Pure extract of Curcumin in powder form (Samy Labs, Bangalore, India) and Doxycycline i.e. pure doxycycline hyclate in powder form (Aristo Pharmaceuticals Limited, Bangalore, India) was used for the purpose of the study. The Curcumin solution was prepared by dissolving 15mg of Curcumin in 10ml of distilled water (1500 ÃŽ ¼g/ml). Preparation of Doxycycline solution was by dissolving 3mg of Doxycycline in 10ml of distilled water (300 ÃŽ ¼g/ml). Extraction of MMP-9: The frozen gingival tissue samples were allowed to thaw to room temperature. Then each tissue sample was homogenized with 2.5% Triton X-100. This was followed by centrifugation of the homogenized samples for 30 mins at 6000 rpm, at 4à ¯Ã¢â‚¬Å¡Ã‚ °C. The resulting supernatant was separated and used for analysis. Detecting the Optimal Curcumin and Doxycycline Concentration: To determine the optimal inhibition of MMP-9 by Curcumin, different concentrations of Curcumin i.e. 300, 500, 1000, 1500 ÃŽ ¼g/ml were added to 50ÃŽ ¼l of gingival tissue extract and incubated at room temperature for 60mins.The addition of increasing concentrations of Curcumin to the gingival tissue extract resulted in decreased MMP-9 activity as shown in Figure 1. Assessing the MMP-9 activity by Densitometric Analysis demonstrated that the concentration of Curcumin required to inhibit more than 50% of MMP-9 activity was 1500 ÃŽ ¼g/ml. Since Curcumin showed more than 50% inhibition of MMP-9 activity at a concentration of 1500 ÃŽ ¼g/ml as compared to the control (without drug), this concentration was used to pretreat the gingival tissue extract in the study. The Curcumin solution with a concentration of 1500 ÃŽ ¼g/ml was freshly prepared prior to processing of each sample of gingival tissue extract. Similarly increasing concentrations of Doxycycline ie 50, 100, 200, 300ÃŽ ¼g/ml were added to 50ÃŽ ¼l of gingival tissue extract and incubated at room temperature for 60mins. Assessing the MMP-9 activity by Densitometric Analysis demonstrated that the concentration of Doxycycline required to inhibit more than 50% of MMP-9 activity was 300ÃŽ ¼g/ml and thus this concentration was used to pretreat the gingival tissue extract in the study. The Doxycycline solution with a concentration of 300ÃŽ ¼g/ml was freshly prepared prior to processing of each sample of gingival tissue extract. Pretreatment of Gingival Tissue Extract with Curcumin and Doxycycline: To compare the inhibition of MMP-9 activity, 50ÃŽ ¼l of gingival tissue extract was preincubated with freshly prepared solution of 50ÃŽ ¼l of Curcumin (1500ÃŽ ¼l/ml) and 50ÃŽ ¼l of Doxycycline (300ÃŽ ¼l/ml) solution for 60mins at room temperature in separate vials. In addition, 50ÃŽ ¼l of extract was also incubated with 50ÃŽ ¼l of distilled water which was used as the control. Assay for MMP-9 Activity: The presence of MMP-9 activity in collected samples was studied by gelatin zymography. Sodium Dodecyl Sulphate-Poly Acrylamide Gel Electrophoresis (SDS-PAGE) on 10% polyacrylamide containing 10% SDS copolymerized with 1g/l gelatin was used to pretreated tissue extracts under non reducing conditions without prior boiling. After electrophoresis, in order to regain the enzyme activity, the gels were rinsed with 2.5% Triton X-100 for 1hr to remove SDS thus allowing the protein to denature. The gels were then immersed in a proteolysis buffer containing Tris- HCl 50 m M/l (pH 7.6) and CaCl2 20mM/l and incubated at 37  ºC for 16 hours. The gels were subsequently stained Coomassie Blue (0.25% Coomassie Brilliant Blue R250, 40% methanol, 10% acetic acid). Gels were destained (30% methanol, 10% acetic acid and 60% water) until white bands appeared clearly from the blue background. These bands of gelatin lysis detected against the blue background as seen in Figure 2, represented enzymatic act ivities. RESULTS The presence of MMP-9 was studied. The enzymatic activities were detected as unstained bands on gelatin gel by zymography technique. In order to measure the relative MMP-9 levels, multi-image gel documentation systems were used to scan the clear zones and the percentage of inhibition was analyzed. Significant differences were found in the MMP activity in treated groups compared to the control. Figure 3 illustrates the reduction in the MMP-9 activity of each sample of gingival tissue extract when incubated with Doxycycline and Curcumin, expressed as percentage of reduction from the control. Table 1 shows the range, mean values and the standard deviation (S.D.) values for Curcumin and Doxycycline. The mean values show 59.58 % reduction in the MMP-9 activity with the addition of Doxycycline and 61.01% reduction in the MMP-9 activity with addition of Curcumin to the gingival tissue extract under identical conditions. Table 2 shows comparison of MMP-9 inhibitory effect between Doxycycline and Curcumin. The results obtained were analysed statistically using students paired t- test. DISCUSSION Periodontal diseases are the result of destruction of the soft and hard connective tissues surrounding and supporting the teeth. Inflammation is the basic cause of initiation of this breakdown. Research in the field of pathogenesis of periodontal disease has shown that various enzymatic activities which are directed towards the destruction of the pathogen also result in destruction of the periodontal connective tissue. Research has shown that, Matrix metelloproteinases (MMP’s) are one group of enzymes which are responsible for this destruction to a large extent. MMPs are involved in a number of physiological events including, tissue remodeling and pathological diseases such as periodontal disease and are the major players in collagen breakdown during periodontal destruction. MMPs are normally tightly regulated and disruption of this regulation leads to the pathologic breakdown of connective tissues. Higher levels of MMPs in the periodontal tissues provoke an imbalance between the production and degradation of collagen, causing tooth attachment loss. Especially, PMN derived MMPs (MMP-8 MMP-9) are the main proteinases related to tissue destruction and remodeling events in periodontal diseases. Numerous studies have substantiated the relationship between MMPs and periodontal diseases, with findings of significantly higher MMP-9 levels in patients with periodontitis as compared to healthy controls.4, 5, 15 With this understanding of the role of host immune response in periodontal destruction the possibility of host modulation so as to reduce the destructive aspects of the host response and hence reduce the damage to the periodontium was investigated. First group of drugs that showed this host modulation activity were Tetracyclines. Studies have demonstrated that tetracycline could significantly inhibit collagenase activity in GCF and gingival tissue, even at lower dosage than traditional antimicrobial dosages ie sub antimicrobial dosage.3 Tetracyclines inhibit collagenases by binding to the Ca2+ or Zn2+ (cations) required for the activation of MMPs such as collagenases and gelatinases.16 It is also possible that tetracyclines can inhibit synthesis of neutrophil-derived oxygen radicals, suppressing neutrophil migration and degranulation.17 However, microbial resistance to tetracyclines has been reported.7 In addition, long term treatment can result in other side- effects such as anorexi a, nausea, epigastric distress and fatty liver. A few recent studies on collagenase inhibition suggested that, like tetracyclines, herbal extracts are also potent inhibitors of pathologically elevated collagenases and hence they may be used as an alternative adjunct in the management of periodontal diseases.18, 19 Ayurvedic drugs like Neem, Triphala, Bakul etc have been used therapeutically since ancient times to treat diseases, including periodontal diseases. With the advent of modern synthetic drugs their convenience of standardized dosage form, dramatic efficacy in acute conditions and most of all simplicity of usage, there was a decline in the use of the plant medicines. But a long term treatment, with these synthetic drugs, has many adverse effects and they are also not cost effective. As Ayurvedic drugs, are widely acclaimed for their minimal side-effects and cost-effectiveness in India, they are now again being used extensively in treatment. Use of herbal extracts in treating periodontal diseases does not produce side effects of tetracycline compounds as well as other synthetic drugs. It has been shown that certain ayurvedic medicines also have the host modulation effect, similar to that of tetracyclines. A few recent studies conducted on collagenase inhibition by herbal extracts suggest that, like tetracyclines, herbal extracts are also potent inhibitors of pathogenically elevated collagenase and hence may be used as an alternative adjunct in the management of periodontal diseases.18, 19, 20 Turmeric which has Curcumin as its active constituent has been shown to have anti-inflammatory, anti-oxidant, anti- bacterial, anti- viral activities etc.10 Its anti- inflammatory activity has not been investigated in periodontal diseases. With the above details in mind the present study was conducted to evaluate the anti-inflammatory property of Turmeric. In the present study the anti-collagenase activity of Curcumin was compared with that of Doxycycline which has proven anti-collagenase activity. In the present study we chose Doxycycline because it has been proved that it is a more potent collagenase inhibitor as compared to minocycline and tetracycline.6 Studies have shown that Curcumin down-regulates MMP-9 activity13, 14, 21 and thus, in the present study we chose Curcumin to find out its anti-collagenase activity by checking its effect on MMP-9 activity. Research has shown that the predominant MMPs in inflamed gingival and periodontal tissues are PMN- type MMPs (MMP-8 MMP-9). Elevated activity of gelatinases (MMP-2 and MMP-9) has also been found in inflamed gingival tissues from chronic periodontitis patients.5, 22 The activity of PMN- type MMPs has been found not only to positively correlate to the severity of inflammation and pocket depth but also the amount of these enzymes recovered in an active rather than latent form appears to increase with greater severity of periodontal disease in the gingival tissue.20 Thus, since the above studies have shown that activity of PMN- type MMPs is increased in inflamed gingival tissues, in the present study we decided to use gingival tissue samples that were obtained from the patients diagnosed clinically with chronic periodontitis. The reduction in the MMP-9 activity of each sample of gingival tissue extract when incubated with the drugs .i.e. Doxycycline and Curcumin, was expressed as percentage of reduction from the control (without drug). The mean values showed 59.58% reduction in the MMP-9 activity with the addition of Doxycycline and 61.01 % reduction in the MMP-9 activity with addition of Curcumin to the gingival tissue extract under identical conditions. These results show that Curcumin has a significant inhibitory effect on PMN-type MMP-9, and this inhibitory effect of Curcumin is comparable to that of Doxycycline when the percentage of inhibition as compared to control was analysed. Curcumin also showed a significant reduction in the MMP-9 activity with an average inhibition of about 61% which is also statistically highly significant (p 23 and 12 g per day.24 But the overall results show that Curcumin has the ability to significantly inhibit the MMP-9 activity. The present study suggested that Curcumin could produce significant inhibition of MMPs at 1500 ÃŽ ¼g/ml concentration, which is well under the safe drug profile confirmed by toxicological studies.23, 24 Thus this study shows that Doxycycline and Curcumin possess anticollagenase activity in vitro. The finding of the present study is significant and confirms the use of Curcumin in treating periodontal diseases. A recent in vivo study showed that Curcumin modulates periodontal disease and had potent anti-inflammatory effects when it was systemically-administered in ligature-induced periodontitis in rats.25 Studies have shown that one of main mechanisms for the anti-inflammatory effects of Curcumin may be the inhibition of NF-ÃŽ ºB (nuclear factor kappa B).13, 25 The Curcumin-mediated inhibition of MMP-9 gene expression appears to occur via NF-ÃŽ ºB and AP-1 (Activator Protein-1) because their DNA binding activities were suppressed by Curcumin.14, 21 When compared to tetracycline, Curcumin has better anti-inflammatory effect, is more cost effective and has minimal side effects and thus can be tried as a substitute for Tetracycline as an anticollagenase agent. Curcumin also allows suppression of collagenase activity well within the safe dosage profile confirmed by toxicological studies. The in vivo environment is substantially different, and inherent limitations of an in vitro replication may constrain our understanding of the systemic effects of Curcumin. Further in vivo studies of Curcumin are needed to define its toxicological profile before making it a part of the therapeutic regimen in periodontal treatment. CONCLUSION In the light of observations from the current study it can be concluded that Doxycycline and Curcumin possess anticollagenase activity in vitro. Since Curcumin has better anti-inflammatory effect compared to Tetracycline, Curcumin being more cost effective and with no side effects can be tried as a substitute for Tetracycline as an anticollagenase agent. Thus Curcumin may have therapeutic potential as a host modulation agent in periodontal diseases.

H.G. Wells :: English Literature

H.G. Wells Herbert George Wells was born in 1866 in Bromley, Kent. His career as an author was fostered by an unfortunate accident as a child. He broke his leg and spent the mandatory rest period reading every book which he could find. Wells was awarded a scholarship and furthered his education at the Normal School of Science in London. It was at the Normal School that Wells came under the wing of the famous biologist Thomas H. Huxley. Wells' "science fiction" (although he never called it such)was clearly influenced by his studies at the Normal School and his interest in biology. H.G. Wells gained fame with his first major fiction work: The Time Machine in 1895. Soon after the publication of this book, Wells followed with The Island of Dr. Moreau (1895), The Invisible Man (1897), and perhaps his most famous popular work: The War of the Worlds (1898). Over the years Wells became concerned with the fate of human society in a world where technology and scientific study were advancing at a rapid pace. For a period he was a member of The Fabian Society, a group of social philosophers in London. Wells's later works became less science fiction and more social critique. The accuracy of the "science" in Wells's work has often been called into question. It is rumored that Wells and the French novelist Jules Verne actually criticized each other's writing. Wells's claim was that "Verne couldn't write himself out of a paper sack" and Verne accused Wells of having "scientifically implausible ideas." The science may not be accurate, but the adventure and philosophy in those books makes Wells' early science fiction fun and fascinating to read. Herbert George Wells was born in 1866 in Bromly, a small town near London. He attended college and graduated with a degree in biology. His lower-middle-class background and his knowledge of science influenced his writings. He thought that science would make a better world. He also thought that that humans would destroy their own race by having a big atomic war and eventually kill each other off. Some of the books Wells wrote were The Time Machine, The Invisible Man The War of the Worlds and The Island of Doctor Moreau. He was very famous in his lifetime, and his books sold well. His book War of the Worlds was a radio drama, performed on Halloween night in 1938. Many people tuned in after they said "This is only a story", so they thought that Martian aliens were attacking Earth. So people grabbed their rifles and jumped in their cars and took off. H.G. Wells died in his sleep on
