Evidence-Based Practice In Nursing Essay Example | Topics and Well Written Essays - 1000 words

Evidence-Based Practice In Nursing - Essay Example In the field of nursing and medicine, the already existing medical knowledge is undergoing advances with every passing minute. For that matter, it is important for a student nurse or a practicing one to be in touch with these developments and a feasible way for that is research conduction. It not only broadens the horizon for the researcher but also if the conducted research is good enough it proves to be a useful tool for fellow professionals in the setting. Mosby’s Medical Dictionary (2009) defines Evidence-Based Practice as health care practice in which the practitioner, be it the doctor, nurse or any other healthcare professional, finds sifts through and then uses the latest and appropriate research findings for his clinical decision making. The evidence-based practice has been integrated into almost all professions including medicine, nursing, psychiatry, law, etc. With the ever improving sophistication of professional dealings, the responsibility increase on the shoulders of a nurse, a doctor or any other professional for that matter, to provide the best possible quality of service. This is where evidence-based practice comes into play. By developing patient-centered approaches in the delivery of quality care using the latest evidence available, evidence-based care can be implemented in nursing practice (Emanuel, et al. 2011). Field and Lohr (1992) define clinical practice guidelines as statements which are developed systematically in order to assist practitioners and patients alike in their decision making regarding requisite health care for various scenarios.

Qualitative General Depression Essay Example | Topics and Well Written Essays - 1000 words

Qualitative General Depression - Essay Example The purpose of our study was to investigate adolescent’s experiences with depression: how depression affected their relationship, their academic performance, their behavior with family members as well as treatment they have received. A comparison was then made on how qualitative study investigates the experience of depression compared to quantitative study in the following aspects. Data collection This survey involved Semi structured interviews of fifteen young adults who had been diagnosed with and treated for the major depression disorder between the ages of 15-19. When collecting data, two approaches were used: qualitative and quantitative research. Quantitative approach on the experience of depression applied more easily than qualitative research. It involved sampling the fifteen teenagers and the interview was audio taped for further reference. When collecting this data, the findings were summarized as follows: all the fifteen adolescents experienced significant factors i n their family concurrent with the time of their first episode e.g. hatred and been neglected, all the fifteen adolescents were not involved in planning or even involved in treatment during their hospitalization, depression caused these teenagers’ broken relationships and traditional school setting did not help the teenagers in dealing with depression hence the great impact. Data collected in quantitative research was hard and numerical. ... It can also be used in studying human behavior and the social world which is inhabited by human beings. Qualitative research helps us to adequately answer the question why? E.g. why things are the way they are in our social world. For example in our study, we were able to answer the question why depression has caused many broken relationships between these teenagers. The answer was that, the public as well as the private schools did not help these participants to recognize or even manage their depression. They were not even involved in planning nor were they kept involved of their treatment during their hospitalization hence this had a great impact on their relationships. Qualitative data collection describes tests and examines cause and effect relationship e.g. it shows a relationship between depression and family systems. Data collected shows us that there has been a dying relationship between the family members and the depressed adolescent as a result of behaviors’ which ar e associated with depression e.g. smoking. Quantitative methods of data collection produce legitimate scientific answers and this can be seen as hard data. On the other hand, qualitative data collection produce soft data, which is seen as inadequate in providing answers and in trying to generate any, change (Strauss, & Corbin, 2000) Sample recruitment When sampling, the sampling procedures in each case are complex hence must meet the criteria of the data collection strategy. A sample in both qualitative and quantitative approaches is required which is a representative of the large group. We sampled the fifteen teenagers and this was a representative of the large population of the depressed adolescents in most of our societies today. Sampling in this case is recommended since it becomes

Corporate Social Responisbility Research Paper Example | Topics and Well Written Essays - 1000 words

Corporate Social Responisbility - Research Paper Example This notion of corporate social responsibility has been heavily debated on in recent years so much so that researchers have called into question the existence of the â€Å"social† aspect in â€Å"corporate social responsibility†. Advocates of CSR have increasingly defined it in terms of human rights, ethics, closures of plants, relations with employees and the environment. A more comprehensive definition of CSR and sustainability encompasses all three foundations of sustainability, including the people, economy and the environment. If only the social and environmental development is taking place that is referred to as â€Å"bearable† (Chick and Micklethwaite 83). If only the social and economic development is taking place, that is referred to as â€Å"equitable†, whereas, if only the environmental and economic development takes places, that is referred to as â€Å"viable† (Chick and Micklethwaite 83). CSR is achieved only when all three dimensions d evelop simultaneously; that is, it is bearable, equitable and viable (Chick and Micklethwaite 83). The very mention of CSR calls into question the reason for business’ existence. Whether or not businesses should be responsible for the society and environment remains questionable since the primary purpose of a business is to satisfy its shareholders and generate profits. This is the line of argument used by classical theorists who are against the practice of CSR. According to Milton Friedman, the only social responsibility of a corporate entity is that of doing business in an open competitive marketplace that is free of deception and any fraud by utilizing its resources in order to increase profits (Friedman 6). The classical advocates further maintain that managers are mainly responsible for catering to shareholders’ interests by enhancing financial returns to the business. Practicing CSR may lead to the dilution of economic productivity since the investments made in C SR may be irrecoverable (due to the non-profit nature of CSR activities) (Friedman 6). However, advocates of CSR base their arguments in favor of the same for various reasons. Usually, companies engage in such disclosure for two main reasons: achieving a competitive edge by enhancing employee morale and goodwill and pressure by external stakeholders such as governments, environmental agencies etc. Not adhering to the latter’s demands would mean a loss in company’s goodwill and, hence, profits. This leads us to the argument related to stakeholder view used by proponents of CSR. This view was conceptualized as early as in the 1970’s by Freeman who described organizations in terms of the managers’ relationships with stakeholders (Garriga and Mele 59). A stakeholder is typically any individual entity or group that has an impact on, or is affected by the corporation’s goals and objectives (Garriga and Mele 59). Companies can reconcile the conflicting ob jectives amongst stakeholders by engaging in a successful CSR dialogue with them in which the company gives something of value (such as a public service) to a significant community in lieu of popular support from groups and individuals within the environment. Advocates of CSR further state that firms are required to exercise duty of care when dealing with both primary and silent stakeholders (such as the community) (O’Riordan and Fairbrass 748). By recognizing the fact that shareholders’ interests cannot be satisfied without satisfying (to some degree) the

Dispostional Personality Theories Essay Example for Free

Dispostional Personality Theories Essay The two most common dispositional theories are Allport’s psychology of the individual theory and the trait and factor theory. Allport’s psychology of the individual theory emphasized that people are unique, even though they may share traits in common, and those unique qualities are what should be focused on. â€Å"More than any other personality theorist, Gordon Allport emphasized the uniqueness of the individual. He believed that attempts to describe people in terms of general traits rob them of their unique individuality†. In order to focus on the individuals uniqueness Allport felt that a broad theory is more useful than a narrow one and he would use information from different theorist in his research. For many years there has been much debate about how many traits actually have an effect on an individual’s personality. In recent years the majority of theorist have come to the conclusion that five is the magic number. Esyneck, McCrae, and Costa have focused their studies on the trait and facto theory and have done much research using standardized tests, clinical observations, and observations from friends and families of the individuals studied. â€Å"Trait and factor theories of personality are based on factor analysis, a procedure that assumes that human traits can be measured by correlational studies†. Each of these theories have different approaches to explaining an individual’s behavior. Both Allport’s psychology of the individual theory and the trait and factor theory have its own effect on individual personalities. Interpersonal relationships are influenced by each of these theories in its own way as well.

The History Use Of Prosthetics Health And Social Care Essay

The History Use Of Prosthetics Health And Social Care Essay The term Prosthesis can be defined as an artificial replica that replaces human damaged or lost body part. In the field of arthroplasty or joint replacement surgery, prosthesis is defined as an artificial joint that replaces the arthritis affected or damaged human articulation (i.e., bone joint). The primary objective of the arthroplasty is to relief patients from arthritis pain in addition with restoring joint functions. Though in most of the cases the reason behind the arthroplasty is the arthritis pain, its not only the reason. Human articulations can be damaged by severe impacts or unusual stresses. Prostheses are usually made for human main joints such as hip, knee, elbow, shoulder, wrist etc. Long term results of the arthroplasty depend to a great extent on the quality of prosthesis implantation. The application of the robotics technology in the field of arthroplasty reduces the inaccuracy that occurred in conventional joint replacement surgery such as misalignment, rotation er ror, resection etc. On the other hand, in the field of biomechatronics (i.e., the science of fusing artificially intelligent devices with the human body), prosthesis is defined as an artificial substitute for a missing body part. Human limb amputation can causes due to trauma, tumor, congenital, disease, etc. According to biomechatronics, prostheses are considered as those which replace human lost arms and legs. The development of the biomechatronics provides useful technology for the robotic prosthesis. Robotic prosthesis act as an extended body part of the amputees by using which amputees can be able to perform his/her daily life activities and take care of them by using their own body functions. As a result, robotic prostheses provide an independent life and more productive role of these people in the society. In addition with the prostheses mentioned above, artificial eyes, teeth, artery, and heart valves are also correctly termed as prostheses. TRANSHUMERAL PROSTHESIS FOR ABOVE-ELBOW AMPUTEES Transhumeral Prosthesis can be defined as a prosthesis that is designed for the people who have lost their arm just above the elbow joint (i.e., above-elbow amputees). Human arm amputation can caused due to congenital (birth defect), tumor, trauma, disease, etc. circulatory disease, cancer and infections are considered as the major categories of disease which may require surgical removal of human arm. Moreover, the civil wars and more specifically wars in Sri Lanka, Iraq and Afghanistan producing an unprecedented number of amputees. Although nothing can ever become a perfect substitute for a missing arm, the intension of the transhumeral prosthesis is to compensate for the lost functions of the above-elbow (AE) amputees absent arm, so that they can lead an independent life and play more productive role in the society. HISTORICAL EVOLUTION OF THE PROSTHETIC ARM Prostheses have been found around for thousands of years, however real advancement and fabrication of the prostheses have started about 500 years ago [01]. According to the medical museum exhibited at the University of Iowa titled History of Prostheses, earliest prostheses were used by soldiers dating back to 484 B.C. Hegesistratus; a Persian soldier around 490 B.C. cut off part of his own feet in order to escape from the prison and later replaced it with a wooden foot [02]. In 61 A.D., Pliny the Elder wrote about the Roman General Marcus Sergius who had lost his right arm during the Second Punic War (218-201 B.C.). Later he had replaced that by an iron arm to support his shield and he returned to battle [03]. During the middle ages, 15th and 16th centuries cosmetic prostheses were usually made from iron. At that period, blacksmiths and armor makers designed the prostheses for the soldiers after modeling their suits of armor. In the 16th century, the great French arm surgeon Ambrose Pare, designed several limb prostheses in addition with practicing surgical amputation. In 1818, Peter Baliff appears to have been the first person to introduce the use of the trunk and shoulder girdle muscles as sources of power to move the prosthetic arm. In 1844, the first transhumeral amputation replacement used Baliffs principle to apply flexion for the elbow joint [03]. The prosthetic arm using this concept is termed as Mechanical or Body Powered prosthetic arm and still extremely famous among the amputees society. By 1860, the Crimean and Italian campaigns of the French Empire left many soldiers in need of prostheses, and their call was answered by the Comte de Beaufort [01] [03]. The Comte de Beaufort designed several limb prostheses using the articles of clothing, pulleys and levers. After the World War I and II, a tremendous loss of manpower in USA and Europe served as a catalyst for the rapid development of the prosthetic arm. In 1948, N. Wiener proposed the concept of Cy bernetics i.e., the study of control and communication between the human and the machine [04], which plays an important role later for the development of the prosthetic arm. In 1949, Samuel Anderson created the first electrically powered prosthetic arm using the external power with support from the US Govt. and IBM. The first myoelectric arm was developed by Russians in 1958 and later on Otto Bock Company revealed the commercially available prosthetic arm for general application which was the first made versions of the Russian design [03]. CLASSIFICATION OF THE PROSTHETIC ARM Prosthetic arms can be grouped into three general categories: 1) Non-functional or Cosmetic Prosthetic Arm As the name implies functioning of these prostheses has less priority than the appearance, weight, wearing comfort and easy handling. These are the oldest and available for 2000 years. Though cosmetic prostheses offer a more natural look and feel, they sacrifice functionality and versatility while also being relatively expensive [05]. 2) Mechanical or Body Powered Prosthetic Arm The power to operate these prostheses comes from the users own body. In this system, the user wears a harness that translates the shoulder motion into elbow flexion motion and action of gravity force generates the elbow extension motion. The earliest model of this prosthetic arm was the Ballif arm [06]. These prosthetic arms are light weight and less expensive than the others however it requires large amount of forces to actually move the elbow [07]. 3) Externally Powered Prosthetic Arm Most advanced commercially available prosthetic arm in which power to operate the prosthetic arm comes from the external sources such as electric motor and battery pack. Most of these prostheses are operated by using users stump arm muscles EMG signals. This type of prostheses provides greater proximal functions, increased cosmetic appeal but also tend to be much heavier and expensive than any of the other categories [07]. Present State and Proposed Transhumeral Prosthesis Recent progress in biomechatronics technology brings a lot of benefit to increase the mobility of above-elbow (AE) amputees in their daily life activities. A transhumeral or AE prosthetic arm is used to compensate for the lost functions of the AE amputees absent arm. A number of commercial prosthetic arms have been developed since last few decades. However, many amputees have not used them due to the discrepancy between their expectations and the reality. The main factors causing a loss of interest in presently available prosthetic arms include low functionality and poor controllability [08]. Since the concept of Cybernetics proposed by N. Wiener [04], a number of research works have already been carried out and are ongoing for the development of prosthetic arm. At present, Utah arm, Boston Elbow, and Otto Bock are considered as the pioneers in this field which are shown in Fig. 1 [09]-[12]. However, currently, commercial prosthesis available on the market for the AE amputees provides a limited DOF. Most of these prostheses provide elbow flexion-extension motion with a terminal device attached at the end. In addition to the elbow motion, some prostheses provide forearm supination-pronation motion and a single DOF at the terminal device for grasping object. Some passive DOF, which are useful to generate an optimal pre-determined configuration during performing certain tasks [13], are sometimes included in the prostheses. Commercially available expensive cosmetic prostheses offer a more natural appearance and simple control. However, their dexterity is relatively very poor compared to the human arm. Human arm generates precise and complex motions during daily life activities which are almost impossible to be generated by using a limited DOF prosthetic arm. As a result, the presently available commercial prostheses have failed to gain wide acceptance among AE amputees. Figure 1: Commercially Available Externally Powered AE Prosthetic Arm [14]. In order to improve the quality of life of AE amputees and to increase their mobility in daily life activities (like, eating, drinking, dressing, brushing etc.), a 5 DOF externally powered transhumeral prosthesis is proposed in this thesis. The prosthesis is designed to generate elbow flexion-extension, forearm supination-pronation, wrist flexion-extension and radial-ulnar deviation, and hand grasp-release motion. Currently, no commercial transhumeral prosthesis provides a combination of wrist flexion-extension and radial-ulnar deviation motion, which have uttermost importance to perform daily life activities. In recent years, a number of prostheses capable of generating multi-DOF motion have been proposed for upper limb amputees [13], [15]-[19]. However, none of these provide a combination of forearm and 2 DOF wrist motion with the exception of an arm designed for above-wrist amputees to provide wrist flexion-extension and forearm motion [18]. Bio-Mechanics of Human Upper Limb Before develop a robotic arm system to mimic to the human arm, the physics of the human upper limb should be thoroughly studied. Accordingly the upper limb mainly consists of three major components, the shoulder complex, elbow complex and wrist joint. Mainly the shoulder complex is built with three bones, clavicle, scapula and humerus and four articulations: the glenohumeral, acromioclavicular, sternoclavicular and scapulothoracic, with the thorax as a stable base. The only point of skeletal attachment of the upper extremity to the trunk occurs at the sternoclavicular (SC) joint. At this joint the clavicle joints to the sternum, the middle bones of the rib cages. The clavicle is connected to the scapula at its distal end via the acromioclavicular (AC) joint. At this joint, most of the movements of the scapula on the clavicle occur, and the joint handles large contact stresses as a result of high axial loads that are transmitted through the joint. The scapula interfaces with the thorax via the scapulothoracic (ST) joint. This is not a typical articulation, connecting bone to bone. Rather, it is a physiological joint containing neurovascular, muscular, and bursal structures that allow for a smooth motion of the scapula on the thorax. The final articulation in the shoulder complex is the shoulder complex is the shoulder joint, or the glenohumeral (GH) joint. Motions of the shoulder joint are represented by the movements of the arm. This is a synovial ball-and-socket joint that offers the greatest range of motion and movement potential of any joint in the body. The shoulder complex can be mimic to a ball-and-socket joint and can be modeled accordingly. The proximal part of the humerus, humeral head and the female part of the scapula, glenoid cavity respectively act as the ball and the socket of the joint. The main motion of the shoulder joints are shoulder flexion/extension, shoulder abduction/adduction and internal/external rotation. During this each motion, the position of the centre of rotation of the shoulder joint changes. The distal part of the humerus is connected to the elbow joint or the radioulnar joint. The elbow is considered a stable joint, with structural integrity, good ligamentous support, and good muscular support. It consists of three bones of the arm and the forearm, humerus, radius and ulna. Movements between the forearm and the arm takes place at the ulnohumeral and radio-humeral articulations, and movements between the radius and the ulna take place at the radioulnar articulations. The ulnohumeral joint is the articulation between the ulna and the humerus and is the major contributing joint to flexion and extension of the forearm. The joint is the union between the spool-like trochlea on the distal end of the humerus and the trochlear notch on the ulna. The second joint participating in flexion and extension motion of the forearm is the radiohumeral joint. At the distal end of the humerus is the articulating surface for this joint, the capitulum, which is supheroidal and covered with cartilages on the anterior and inferior surface. The top of the round radial head butts up against the capitulum, allowing radial movement around the humerus during flexion and extension. The capitulum acts as a buttress for lateral compression and the other rotational forces absorbed during throwing and other rapid forearm movements. The third articulation, the radioulnar joint, establishes movement between the radius and the ulna in pronation and supination. There are actually tw o radioulnar articulations, the superior in the elbow joint region and the inferior near the wrist. Also, midway between the elbow and the wrist is another fibrous connection between the radius and the ulnar, recognized by some as a third radioulnar articulation. The hand is primarily used for manipulation activities requiring very fine movements incorporating a wide variety of hand and finger postures. Consequently, there is much interplay between the wrist joint positions and efficiency of finger actions. The hand region has many stable yet very mobile segments, with complex muscle and joint actions. The wrist consists of 10 small carpal bones but can be functionally divided into the radiocarpal and the midcarpal joints. The radiocarpal joint is the articulation where movement of the whole hand occurs. The radiocarpal joint involves the broad distal end of the radius and two carpals, the scaphoid and the lunate. There is also minimal contact and involvement with the trinquetrum. This ellipsoid joint allows movement in two planes: flexion-extension and radial-ulnar flexion. It should be noted that wrist extension and radial and ulnar flexion primarily occur at the radiocarpal joint but a good portion of the wrist flexion is developed at the midcarpal joints Wrist motions are generated around an instantaneous center. The path of the centrode is small, however, customarily, the displacement of the instantaneous center of rotation is ignored and the rotation axes for the flexion/extension and ulna/radial deviation are considered to be fixed. The axes pass through the capitate, a carpal bone articulating with the third metacarpal. Although it is considered that wrist joint motions are generated with respect to the two axes, some research [11] has proved that the motions are generated with respect to four axes. The wrist flexion axis and the extension axis are different. Similarly the radial deviation axis and the ulnar deviation axis are also different. Therefore, the 2DOF of the wrist are through four axes. Although flexion and extension motions have different axes they are intersected in a point in capitates. Similarly, radial and ulnar deviations axes are also intersected. When we consider that flexion and extension motions have one axis and similarly ulnar and radial deviations have one axis, the slight offset of the rotational axes of the flexion/extension and the radial/ulnar deviation is approximately 5 mm [8], [12]. In addition the motion ranges of the upper limb are as follows.[23] G. Thompson and D.

Exemplification Essay: War and World Peace :: Expository Exemplification Essays

World Peace is something that will never happen. Too many countries have too much military power and don't want to give in to any other country. War is something that the world is going to have to deal with because there has been very few years over the history of the world that have been war free. Like one quote by an unknown author says, "Peace is rare: less than 8% of the time since the beginning of recorded time has the world been entirely at peace. In a total of 3530 years, 286 have been warless. Eight thousand treaties have been broken in this time." Albert Einstein, born on March 14, 1879 is one of the most influential people of the modern era. (Einstein) As a physicist he changed our understanding of the universe. He was very outspoken about the significant political and social issues of his time. As a Jew he advocated a moral role for the Jewish people. Over his scientific career, he was on a mission for the universal and indisputable laws that govern the physical world. Science was Albert Einstein's love, but he always found time to devote many of his efforts to political causes that were close to his heart. He strived for peace, freedom, and social justice. He became an active leader of the international anti-war movement. (Albert Einstein Archives) Einstein died on April 18, 1955. (Einstein) Einstein said, "I don't know what kind of weapons will be used in the third world war, assuming there will be a third world war. But I can tell you what the fourth world war will be fought with- stone clubs." This means that whatever weapons are used in the third world war will knock us back in time because they will be so powerful. That is also the reason he doesn't know what they will be because they will be so far advanced compared to his time. This is very possible because of the advances some countries have made in their military strength. For example, the United States executed 1054 nuclear tests between July 16, 1945 and September 23,1992. They also executed two nuclear attacks in that period although the number of actual bombs tested in that time period is far greater.

Online grading system Essay

Chapter I Nowadays, computers and other technology are very useful in the fields of education especially in our daily activities. The importance of computers cannot be denied in the fields of education because as we all know, computers are very significant in terms of learning and working. With those technologies, we can save time for other activities. Computers connected with internet also serve as useful tools for communication. Through this process various types of descriptive information and measures of students’ performance are converted into grades that summarize students’ accomplishment. Online Grading System is designed to provide incentive reward for achievement and assist in identifying problems of the student. Grading System is the most commonly used in computing and analyzing the performance, talent and skills of student? Grading system is an exercise in professional judgment on the part of the teachers. It involves the collection and evaluation of evidence on students’ achievement or performance over specified period of time. Parents can view and updated on the performance of their children. While teachers work load can be lessen through computing the grades automatically. Online Grading System of Cauayan South Central School (CSCS) is design to provide the system where in the parents of the students of Cauayan South Central School (CSCS) can access the grades of their children. Originally, the school was opened in the year 1953 through the initiation and encouragement of the late Teodoro Cariňo, who was at that time the Division Academic Supervisor from Pangasinan who resided here in Cauayan. The Teaching Staff welcomed and embraced the growing enrolment. Though their sincere and dedicated service to the community, they begged for more school buildings to house the school children hungry for formal education. From this point of view, the school will serve as a potent instrument because of the vast extent of outreach and of the size of the populace. To optimize this contribution to social, intellectual and cultural development, it has to maintain and accelerate its progress to be able to cope fully with changing world. It is believed that with the time tested, loyalty and cooperation of the school officials and teachers, the CSCS will surely be the best show window of the City Division. Thus, the above reasons drove the researcher to conduct a study regarding the Online Grading System, which aims to improve their present system.

SCOPE AND LIMITATION This study was conducted at Cauayan South Central School involving the pupils, teachers and parents during the School Year 2014-2015 This study focused on the assessment of the student’s grades of Cauayan South Central School and the development of the Online grading System. This study is limited only to the student’s grade and does not cover the other transaction of the school. It cannot be used for conversation. If the instructor submitted wrong grades of student, the online system is not  reliable in human error. The grade encoding process relies on internet connection Chapter 2 Review of Related Literature and Studies To be familiar with the study, the researchers gathered some information through surfing the internet and scanning text book to improved their related literature and studies. Local Literature According to Torall (200) think with all the tough times were facing, having a website now is very important among small and medium enterprises and use it as medium to sell product and disseminate corporate information. Having a website communication where one can join. Foreign Studies According to Moreno (2000), School is now in their own website but they got to effectively utilize this technology to bring real benefits to their audience: students, parents, teachers, and school officials. The World Wide Web is one of the most effective communication technologies today. A school website can expand opportunities for parents to communicate with the school and become more informed about the education their children are getting. Teachers can use the school website to share ideas with other teacher and make them available even to everyone else. A school websites can also allow parents to voice out there concerns to school officials. Some parents avoid communicating with their children’s school because they do not feel comfortable talking to teachers or they think their concerns will not be heard while others are simply burned out by their work. When the need arises, many parents and teachers find themselves unable to contact each other. School websites can greatly eliminate barriers in involving parents in the school. Foreign Literature Castro(2000). The World Wide Web is the Gutenberg press of our time. Just above anyone can create their own web. Web site and then present it to the internet public. Some web page belongs to business with service to sell, other to individuals with information to share. Randall(1996) an English professor at the University of Waterloo Canada, heist the author of several books about the internet. Thousands upon thousands of companies, organization, and individuals are looking to the web as an important means disseminating information. If you’re not part of it, you’re already somewhat behind. Jumping onto the web is like jumping onto the biggest stage ever designed. When you put your page in the web, you’re inviting the world become take a look. Most internet user won’t bother, either because they’re not interested or, more likely, because they never get to know your contribution (it’s a huge stage). Realizing that the average person, when they begin to look into CCTV, has little way of knowing where to find expert advice at reasonable cost, we have set up this website to bring together some of the top people and organizations working in this field. The companies and individual found on this web site are those who do not just talk about excellence, but both believe in it, and make sure that it runs through every fibred of there organization and dealing with costumers. Local Studies Guidance for Government Webs site Issued (www.nee.edu.ph.com) The National Computer Center (NCC) recently issued memorandum curricular 2002-01, â€Å"Guidance on Creation of the agency’s official website and compliance to the E-commerce law and stage one of the UN-ASPA stage of E-Government†. The circular further states that the computer agency will coordinate and provide technical assistance to national government agencies (NGAs), Local Government Units (LGU) and state universities and collage (SUCs) to ensure that they have website that will provide basic public information. The basic information includes the following; organizational aims structure and responsibilities of each unit. Mangulit (2001) Book Store Inc. According to Mangulit, Website now number by the millions. There are personal Website, corporate website, small business Website, and so on. And the number of website just keeps on growing each day. Website provides two real value-adding services. Website allows companies to either make more money or save money. Business can make more money by selling their product and services through the website. The website also to save money allow business. According to Ducusin, Many Business School, Individual, and Government agencies at all levels have rushed to establish a presence on the internet. The attraction is the ability to quick and inexpensively provides information to a large number of people. The website can provides the public with information about government agencies also provide about agencies mission, service offered, office hour, and email add for correspondence. Eventually users of the WWW will be able to submit request to an agency for document or other inquires directly though the webpage. Also provide information about the government agencies and the service that they offer. Many of the interactions between citizens and government that require visit to government office could be handling through home page in the internet. Request for permits driver’s license record, documents and forms could all be handled through the internet. Chapter III Technical Background At present, Cauayan South Central School, Cauayan City, Isabela are using manual system in grading of student’s. They are using forms to track the student transaction in the school and then keep it in drawer or cabinet for safe keeping.! PHP platform was used in the development of the program. Since the project is designed as a client server program, two or more networked computers are needed in the school for the implementation of the project. The program will be used by the teachers. The teacher’s and student’s must registered if new and has no record yet in the website. Once the students is already registered in the website and wants to have their grade, the student or the parent will just search student’s record, and then input his or her findings and recommendation in the website for the  update of student’s record. Below are the technologies used in the development of computerized medical and dental record system. Software PHP Platform used in the development of program Microsoft Windows 7,8,XP Operating system (minimum requirement) SQL Server Database 2005 Database (minimum requirement) Google Chrome, Mozilla Firefox, Internet Explorer, RockMelt, and Safari Browsers (recommended use of Google Chrome) Hardware Computer Unit Specification (minimum requirement) 1 gigahertz (GHz) or faster 32-bit (x86) or 64-bit (x64) processor 1 gigabyte (GB) RAM (32-bit) or 2 GB RAM (64-bit) 16 GB available hard disk space (32-bit) or 20 GB (64-bit) DirectX 9 graphics device with WDDM 1.0 or higher driver Internet Connection Ink Jet Printer (for report printing) Network Hub and UTP cables were used in networking the computers. Peopleware System user must be knowledgeable in using computer. Chapter IV Methodology The methodology chapter provides the details of the step by step procedures used in developing the Online Grading System. The project procedures will be explained in detail. Requirements Specification The proponent used the System Development Life Cycle (SDLC) – a structured analysis concept in developing a system. Phase 1 – SYSTEM PLANNING The proponent performed preliminary investigation to the school where we able to identify the process and flow of manual grading. Phase 2 – SYSTEM ANALYSIS After the investigation, the proponent build logical model for the new system based from the user requirements. Phase 3 – SYSTEM DESIGN At this stage the proponent design the user-interface and identify all necessary outputs, inputs, and processes. In addition the proponent design internal and external controls including computer based and manual features to guarantee that the system will be reliable, accurate, maintainable and secure. Phase 4 – SYSTEM IMPLEMENTATION I this phase the proponent constructed the new system. Program is written, tested and documented and system is installed. Phase 5 – SYSTEM OPERATION, SUPPORT AND SECURITY At this point, the clinic staff maintains and protects the system. Based on the phases and deliverables of the SDLC, Figure 1 shows the timeline of the researcher undergone. The entire study is accomplished in 2014 Figure 2? Data Gathering Procedures First, the researcher prepared a letter seeking for the approval from the principal name After seeking approval, the researcher prepared the questionnaires, have them checked and approved by the Research Instructor and then administer the questionnaires to the respondents. Data Gathering Instruments This study made use of the Questionnaires as its main instrument in gathering data. It also made use of interview to support the data and  information gathered from the questionnaires. This will also be supplemented by observations and documentary analysis. Questionnaire The researcher used the questionnaire method in collecting data in a large number of people. The questionnaire undergone different kind of approval; first, the questionnaire was checked by the adviser to make sure that is related to the statement of the problem. Second, the English Critic made sure that the grammar and spelling were ceorrect. Interview The researcher interviewed the principal to obtain pertinent data and accurate information that would help in improving their manual grading. Observation Observation was done by the researcher to get more information about the current process. Internet Researcher The researcher used the internet to collect additional information about Online Grading System. Library Reseacher Library research was done in defining terms in the study and served as a reference in making document analysis from similar studies and procedures. The method helped the researcher and served as a guide on how to organized data that is needed on the study. Figure 3: Input-Process-Output (IPO) model The proponent used the IPO model. In the input column is information or ideas used by the researcher. Processing column are the actions taken upon using input. Output is result of the processing, which is the development of the proposed system. Data and Process Modeling Figure 4: Proposed System Context Diagram The context diagram illustrates the structure of the Online Grading System of Cauayan South Central School. It shows the relationship among the Administrator, Teacher’s, Students. The system has inputs like the student information, teachers information, and user information. To access to the system, the user enters the correct username and password. After the username and password validation, the user can add, delete, edit and view depending of the transaction desired. The system output is the Grade of the Student’s. Data Flow Diagram The researcher used the Data Flow Diagram to understand the flow of the project and at the same for future study. DFD demonstrate the external entities, data storage and the to be performed. In the Lon in process, the user needs to enter his username and password. When the username and password were entered, the system will look for any information matched in the database. As soon as the system confirms that the information given is valid, the system will show the user’s interface. There are different views for the administrator, the student and the teacher.
