Games to Life Essay Example for Free

Games to Life Essay Pong, Super Mario Bros. , and Pac-Man are a couple classic games most everyone has played. These games were some of the first video games ever made and had very little to no violence in them. These video games have now evolved into more graphic, gory, and violent games. This increased violence in video games has caused more aggression in society. On April 20th, 1999 at Columbine High School in Colorado a shooting occurred killing 12 students, 1 teacher and also injured 24 other students. Two students were the cause of this shooting. The two seniors played video games religiously and were big fans of a game named Doom. Doom is a game where players is a space marine who must fight his way through hordes of invading demons from Hell. The two shooters liked and played this game so much that even designed their own based off of it. Eric and Dylan’s, the two shooters, game was created based on the Columbine High School’s floor plan. Their game contained characters based off student at their school whom they did not like. When students, in their game, that believed in God would die they would say â€Å"My Lord, why did you do this to me? † which is what Eric and Dylan believed they would say as they would kill them. When a newer game called Duke Nukem came out, a similar game to Doom, Eric and Dylan were quick to design another levels based on Columbine High School. In this game they had more realistic guns and bombs, which the shooters liked. They also mapped out how they would invade the school and whom they would target in these levels they created. Through both these games, that Eric and Dylan loved to play, inspired them to create there own games using their school as a layout and students as the characters. They planned out how they would approach their shooting and where they would place their bombs based on what they did in their games. They knew whom they would kill first and where they would be. They also placed bombs around the school as they would in the game that thankfully did not go off. Video games have become a big part of our culture in today’s society. When video games first came out they were simple, friendly, and non-violent. Since then video games have become more sophisticated, completive, and especially more violent. Eric and Dylan’s shooting on their school was an act of aggression supported from the violent videos games they played.

The Steam Turbine Technology Engineering Essay

The Steam Turbine Technology Engineering Essay Steam turbine technology is the almost all of electricity generation power plants from biomass used power generation in the world at present. This technology is well established due to availability of cheap or waste biomass in the world. As an example, USA has the installed capacity of electricity generation from biomass around 7000 MW with efficiency of 20 to 25 percent. The biomass Boiler steam turbine systems are expected to find more applications for electricity generation in the future, particularly in situations where cheap biomass, e.g. agro industrial residues, and waste wood, are available. On the technology side, efficiency of these systems is expected to improve through incorporation of biomass dryers, where applicable, and larger plant sizes as well as higher steam conditions. The steam boiler turbine arrangement, woody biomass is combusted in a furnace of a steam boiler with fluidized bed combustion. Heat released during combustion is utilized to raise high pressure and high temperature steam. This steam is expanded through steam turbine, which in turn drives an electric alternator. Exhaust steam from the turbine is condensed and returned to the boiler. Wood fuel is usually shredded to appropriate size and dried utilizing a part of the flue gas, before the fuel introduced into the furnace. This technology has been in existence in many parts of the world, specifically to produce electricity and motive power in the sugar industry utilising bagasse (residue produced after crushing sugar cane) as the fuel. In this modern version of this technology, wood fuel is shredded into very small pieces and combustion is carried out in a fluidised state. Although this improvement increases the cost of fuel preparation and air supply, it improves the combustion efficiency, thus reducing the operational costs and also reducing stack emission levels. A fluidized bed boiler could accept not only chipped wood but also residues such as rice husk, sawdust etc. This technology is widely used all over the world to generate electrical and motive power from solid fuel. The modern versions have incorporated many new features to improve operational efficiency, thus reducing cost of operation and to reduce emission levels. Some of these improvements are: Increasing the pressure of boiler, increasing the vacuum in the condenser, combustion air pre heating and steam reheating. Figure 11 schematically shows the principle of this conventional system Condenser Flue Gas Figure 11: Boiler-steam turbine system Cogeneration Cogeneration is the process of producing two useful forms of energy, normally electricity and heat, utilizing the same fuel source in an industrial plant where both heat/steam and electricity are needed, these requirements are normally met by using either; 1) Plant-made steam and purchased electricity, or 2) Steam and electricity produced in the plant in a cogeneration system. The second option results in significantly less overall fuel requirement. Steam turbine based cogeneration is normally feasible if electricity requirement is above 500 kW. Biomass based cogeneration is often employed for industrial and district heating applications; however, the district heating option would not be applicable in the tropical countries. A number of studies have been carried out on cogeneration in different agro industries, particularly, sugar mills and rice mills. These show that biomass based cogeneration technology is well established in the pulp and paper industry, plywood industry as well as a number of agro-industries, for example, sugar mills and palm oil mills. Normally, there is substantial scope for efficiency improvements in such cases. For example, bagasse is burnt inefficiently in sugar mills in most developing countries because of a number of reasons, e.g., old and obsolete machinery, disposal problems created by surplus bagasse, lack of incentive for eff icient operation etc. Improving the efficiency of biomass-based cogeneration can result in significant surplus power generation capacity in wood- and agro-processing industries; in turn, this can play an important role in meeting the growing electricity demand in developing countries. India has launched an ambitious biomass based cogeneration programme. A surplus power generating capacity of 222 MW was already commissioned by the end of 1999, while a number of projects of total capacity 218 MW were under construction. The total potential of surplus power generation in the 430 sugar mills of the country has been estimated to be 3500 MW. Co-firing Co-firing is set up as an auxiliary firing with biomass energy source in coal fired boilers. The co-firing has been tested in pulverized coal (PC) boilers, coal-fired cyclone boilers, fluidized-bed boilers, and spreader stokers. Due to fuel flexibility of fluidized bed combustion technology, it is currently the dominant technology for co-firing biomass with coal. Co-firing can be done either by blending biomass with coal or by feeding coal and biomass separately and is a near term low-cost option for the efficient use of biomass. Co-firing has been extensively demonstrated in several utility plants, particularly in USA and Europe. Co-firing represents a relatively easy option for introducing biomass energy in large energy systems. Besides low cost, the overall efficiency with which biomass is utilized in co-firing in large high pressure boilers is also high. Current wood production systems in most countries are dispersed and normally can only support relatively small energy plants of capacity up to 5-20 MWe, although dedicated plantations can probably support much bigger plants in the future. Thus, biomass supply constraint also favour co-firing biomass with coal (with only a part of the total energy coming from biomass) in existing co-fired plants in the short term. Whole Tree Energy (WTE) system: The Whole Tree Energy (WTE) system is a special type of wood fired system, in which whole tree trunks, cut to about 25 ft long pieces, are utilized in the process of power generation in an innovative steam turbine technology that uses an integral fuel drying process. Flue gas is used to dry the wood stacked for about 30 days before it is conveyed to a boiler and burnt. Allowing the waste heat to dry the wet whole tree can result in improvement in furnace efficiency with net plant efficiency reaching comparable value of modern coal fired plants. Stirling Engine A Stirling engine is an external combustion engine; working on the principle of the Stirling thermodynamic cycle, the engine converts external heat from any suitable source, e.g. solar energy or combustion of fuels (biomass, coal, natural gas etc.) into power. These engines may be used to produce power in the range from 100 watts to several hundred kilowatts. Stirling engines can also be used for cogeneration by utilizing the rejected heat for space or water heating, or absorption cooling. A number of research institutes and manufacturers are currently engaged in developing biomass fired Stirling engine systems. For example, the Technical University of Denmark is developing medium and large Stirling engines fuelled by biomass. For 36 kWe and 150 kWe systems, the overall efficiency is about 20 percent and 25 per cent respectively. [..] Gasification Gasification is the process of converting a solid fuel to a combustible gas by supplying a restricted amount of oxygen, either pure or from air. The major types of biomass gasifiers are, Fixed bed gasifier, Fluidized bed gasifier, and Biomass integrated gasification combined cycles (BIGCC) Fixed Bed Gasification Fixed bed gasification technology is more than a century old and use of such gasifiers for operating engines was established by 1900. During World War II, more than one million gasifiers were in use for operating trucks, buses, taxis, boats, trains etc in different parts of the world. Currently, fixed bed gasification shows for the most part possible selection into biomass based power generation with capacity up to 500 kW. Although charcoal gasification presents no particular operational problem, the actual acceptance of the technology by potential users is rather insignificant at present, mostly because of low or no cost benefit that it offers. Also, producer gas is less convenient as an engine fuel compared with gasoline or diesel and the user has to have time and skill for maintaining the gasifiers-engine system. However in situations of chronic scarcity of liquid fuels, charcoal Gasifier-engine systems appear to be acceptable for generating power for vital applications. Thus, sev eral gasoline-fueled passenger buses converted to operate with charcoal gasifiers were reported to be in use in at least one province of Vietnam in early 1990s. As reported by Stassen (1993), a number of commercial charcoal Gasifier-engine systems have been installed since early eighties in the South American countries. Wood gasification for industrial heat applications, although not practiced widely, is normally economically viable if cheap wood/wood waste is available. On the other hand, wood gasifiers-engine systems, if not designed properly, may face a wide range of technical problems and may not be commercially viable. Research and development efforts of recent years have been directed towards developing reliable gasifier-engine systems and the technology appears to be maturing fast. Although the demand for wood gasifiers is rather limited at present, a number of gasifier manufacturers appear to have products to offer in the international market. Gasification of rice husk, whic h is generated in rice mills where a demand for mechanical/electrical power also exists, has attracted a great deal of interest in recent years. The rice husk gasifier design that has found quite wide acceptance is the so-called Open Core design that originated in China; this is basically a constant diameter, (i.e. throttles) downdraft design with air entering from the top. The main components of the gasifier are an inner chamber over a rotating grate, a water-jacketed outer chamber and a water seal-cum ash-settling tank. Gasification takes place inside the inner chamber. The char removed by the grate from inside the gasifier settles at the bottom of the water tank. At present, 120 to 150 rice husk gasifiers appear to be in operation in China. A third of the gasifiers are in Jiangsu Province; these include about thirty 160 kW systems and about ten 200 kW systems. A number of rice husk gasifier systems have been shipped to other countries namely, Mali, Suriname, and Myanmar. A husk g asifier system of capacity 60 kW was developed in 1980s to use in smaller mills in the developing countries. This prototype was successfully used in a mill in China, although no other such unit appears to have been built or used. Beside rice husk gasifiers, several other gasifier models have also been developed in China. Presently, more than 700 gasification plants are operating in China (Qingyu and Yuan Bin, 1997). As a result of several promotional incentives and RD support provided by the government, gasification technology has made significant progress in India in the recent years. Up to 1995-96 about 1750 gasifier systems (Khandelwal, 1996) of various models were installed in the different parts of India. The total installed capacity of biomass gasifier system in India by 1999 is estimated to be 34 MW. Besides generating electricity for the local community, it is estimated that the project has also benefited about 11,000 people directly or indirectly. Fluidized Bed Gasification Fluidized bed gasifiers are flexible in terms of fuel requirements, i.e. these can operate on a wide range of fuels so long as these are sized suitably. However, because of complexity in terms of manufacturing, controls, fuel preparation and operation, these gasifiers can only be used for applications of larger capacities compared with fixed bed gasifiers, typically above 2.5 MW. Biomass integrated gasification combined cycle (BIGCC) technology In the gasification gas turbine technology described above, an overall maximum efficiency attainable is 20%. This could be substantially improved, by raising steam utilizing the gas turbine exhaust and driving a steam turbine. A number of BIGCC power plants are in operation in countries such as Sweden and Finland. Gasifier-internal combustion (IC) engine technology In this arrangement, solid wood is first dried and shredded into appropriate size and then converted into a combustible gas in a gasifier. Gasifier is a cylindrical reactor with a throat section, which is narrower than the rest of the reactor. In this throat section, air is introduced through a set of tubes. Wood dried to a maximum of 20% moisture level and shredded into appropriate sizes is introduced at the top of the reactor through an air lock. Up draught gasifiers are widely used for heat applications as they are easier to construct and are more energetically efficient. Such gasifiers are rarely used for motive power or electricity generation purposes due high tar levels in the gas stream. Wood Gasifier Gas Cleaning IC Engine Generator Gas Gas Exhaust Electricity Chart 01: Gasifier-Gas Cleaning-Engine System As the material slowly passes through the reactor, it undergoes physical and chemical changes in the many overlapping zones. First the material is dried in the drying zone, losing all the remaining water. Then the material is pyrolysed into solid char and volatiles. In the next zone the combustion or oxidation zone at the throat of the gasifier, all the volatiles get combusted into carbon dioxide and water. This section liberates all the heat required for the gasification process. In the expanding section below the throat section known as the reduction zone carbon dioxide and steam produced in the upper sections are made to react with carbon, which has reached red-hot stage. In this reduction zone, carbon dioxide and water reacts with carbon to form carbon monoxide, hydrogen, methane and other hydrocarbon mixtures. The oxidation is essentially an exothermic process liberating heat in the action, whereas the reduction zone is an endothermic process making use of heat. The gas mixture so produced is called producer gas. Un-burnt materials in the wood end up as ash and are collected and periodically removed from the bottom. Hot producer gas leaves the gasifier at the bottom of the gasifier under the action of an induced draft fan. Air for combustion in the combustion zone is drawn into the section due to low pressure created under the action of the induced draft fan. Producer gas leaving the gasifier, if mixed with air can form a combustible mixture. It can be used as a fuel in internal combustion (IC) engines or in furnaces or boilers. To be used in IC engines, the gas needs to be treated further. First it must be cooled to improve the volumetric efficiency (to facilitate the introduction of maximum quantity of fuel into the cylinders of the engine). This is done by a jet of water. The water jet also washes away a part of the tar and particulates in the gas. Then the gas needs to be thoroughly cleaned of all traces of tar and particulate matter. This is achieved by passing the gas through a series of filters. If the gas is to be used as fuel in a furnace or a boiler, the cooling and filtering operations may be omitted. If the gas is to be used as fuel for IC engine, then the gas mixed in the correct proportion of air is admitted to inlet manifold. In respect of spark ignition type of IC engines (petrol or natural gas engines), producer gas alone can operate such engines. For compression- ignition type of engines (diesel engines), it is necessary to utilise a minimum quantity (less than 5%) diesel fuel as the ignition source in a well optimised engine. When standard IC engines are fuelled with producer gas, the maximum output of the engine gets de-rated. In respect of spark ignition engines, this de-rating is about 50% (i.e. the new output is 50% of the name plate output). In respect of compression ignition engines, it is insignificant if 30% diesel fuel is used as pilot fuel. This technology to use producer gas from biomass fuel was popularised during the Second World War in the 1940s. During this war, distribution of petroleum fuel was disrupted and was in short supply. Many countries, particularly, USA and Sweden utilised this technology for transport vehicles. With the end of the war, the supply of petroleum was restored and this technology was discontinued. With the increase in cost of petroleum in the 1970s with the formation of OPEC, this technology has once again gained popularity, particularly for off-grid application for decentralised electricity production. In many Asian countries such as India, Cambodia and Sri Lanka this technology is becoming very popular for off-grid applications. In Sri Lanka, this technology was used prior to the introduction of Grid Electricity. In the earlier version, coconut shell charcoal was used as the fuel for the gasifiers. Producer gas from these gasifiers was used to drive slow-speed IC engines. Motive power of the engine was used to drive a single over-head shaft with multiple pulleys driving individual drives. Later, the IC engines were fuelled with furnace oil with injectors and hot bulb. When grid electricity was popularised, these devices were discontinued. At the Government Factory at Kollonnawa, near Colombo, remnants of this system are still available to see. With the increase in oil prices in the 1970s, interests in new and renewable energy resources surfaced again. A few gasifiers with IC engines were introduced through donor-funded projects. Attempts were made by many research institutions to develop this technology locally. These attempts were successful in varying degrees. With the declining oil prices in the late 1980s, the enthusiasm shown in renewable energy declined. Almost all the gasifiers system in the country became inoperative. Three years ago, a team of officials visited India to identify gasifier-IC engine systems for local adaptation. Later a 35kWe system was introduced from India by the Ministry of Science and Technology. For the past two years, this has been operating as a demonstrating unit for off-grid electricity generation. This system will be relocated to a rural area shortly to serve an isolated village community. The 35kWe system consumes 1.6 to 1.8 kg wood per kWh of net electricity generated. Figure 12 below shows a photograph of this system in operation. Figure 12: 35 kW gasifier-IC engine generator Gasifier-gas Turbine Technology The gasifier-IC engine system described in the previous section is more suitable for outputs in the kW to say 1 MW range. To use gasifier system for larger applications in the multiple MW range, gas turbine technology is generally more suitable. A schematic diagram of this technology is shown in 13. Gasifier Biomass Clean-up Flue Gas Gas Turbine Air Ash Figure 13: Gasifier gas turbine technology Biomass integrated gasification steam injected gas turbine (BIG/STIG) technology Gasifier Biomass Clean-up Flue Gas Steam Turbine Condenser Gas Turbine Air Ash A method of improving the efficiency and output of the above-described BIGCC technology is to inject steam into the gas turbine combustor. This increases the output of the gas turbine without consuming power at the compressor. This technology requires very stringent water purification system and other control measures. At this early stage of biomass technology for power generation in Sri Lanka, such complicated technologies are not considered. Figure 19 illustrates this principle.

Ethics and Education :: Free Essays Online

Ethics and Education Before one decides whether or not morals should be a standard part of American public school education, one first must figure out what the purpose of education is. This is a difficult question to answer. Some would say that the purpose of education is to learn facts. Others would add to that and say that one's education should include facts and ideas. Perhaps the goal of education is to create well rounded people who are prepared to face the world around them. Perhaps education should be the pursuit of truth, however, in order to pursue truth, one must also define verity. How do you say which, or who's morals are true or untrue? An important aspect of defining education is deciding what areas of a person's education must be acquired in school, and what areas should be learned elsewhere. The area of morals is sticky in this respect. It is very difficult to know where to draw the line. When deciding this one must figure out where the responsibility of parents ends and where responsibility begins for teachers. One could argue that teachers have the task of being educators and parents the job of care-giving, so therefore all learning, including morals should occur within the schools. This is difficult to say though, because the line between teaching and care-giving is also fuzzy. Part of care-giving is making sure that one's child does not hurt him or her self or others, and that involves teaching. Similarly, part of teaching is making sure that the child is able to learn, which involves care-giving. In modern day society children spend a very large percentage of their time in school, and perhaps to enough time at home for their parents to effectively instill all the morals they need to learn in order to be ethical human beings. Because of this it could be argued that it is the responsibility of schools to teach morals in order for their to be any kind of ethical society at all. By not actively teaching morals it is possible that schools are passively teaching to be immoral. Another question to be raised is whether or not morals need to be learned in order ro function in other areas of education. If this is the case, then another question is whether or not the schools should be responsible for instilling those morals, or if they should expect the Ethics and Education :: Free Essays Online Ethics and Education Before one decides whether or not morals should be a standard part of American public school education, one first must figure out what the purpose of education is.

Introduction I never knew John B. Thompson is a writer in the field of social science and sociology until I read one of his books. He is the author of the book: The Media and Modernity: A Social Theory of the Media. As a professor of sociology and a fellow of Jesus College in Cambridge, he brings out the aspect of social science in the media through in his book. The book is among the most interesting books I have ever read because Thompson explains the relationship between media and modernity using the social theory of the media. As I went through the contents of the book, I could easily see how he uses his study of communication in social contexts. Summary and Analysis In the book, Thompson makes it easy for the reader to understand mass communication in depth. He focuses on the application of mass communication in the contemporary times. He begins by defining the word ‘mass’ in which he argues that the media today does not target the mass but niche markets. I agree with him on the fact that the term ‘mass’ is misleading. It appeals to a vast audience composed of millions of individuals. He uses the most popular day newspaper as an example to illustrate this argument. I see it in films and television programs too. The society that I live in has several categories of audiences. In all social gatherings such as church meetings and cases where the target group of distinct information consists of specific character traits, I normally observe what Thomson refers to as ‘undifferentiated individuals’ (Thomson13). As I read the book, I got some insight on the use of the word ‘communication’. At first, I could not understand what Thomson meant by â€Å"overwhelmingly one way† (Thomson 14), until he contrasted it with face-to-face communicatio... ...n to me. Through the book, one can easily see himself of herself in the description of the society today. Conclusion This is a resourceful book that I would highly recommend to individuals who desire to understand the original theory of the media and how it has affected the modern world. Security agencies and managers in the information departments can learn a lot from the book. It also shows the developments in the media industry from the emergence of printing to the recent media characterized by cutting edge technology. Thompson’s book is a perfect remedy for media-related challenges in the modern world because it explains with real-life examples how mass communication has developed over time. Even though the book offers a few suggestions about the future development of mass communication, a reader can certainly tell that it can only get better and more personal.

Ethics of Affirmative Action Essay -- Ethics Morals

Affirmative Action: Staying on the Road to Equality â€Å"We hold these truths to be self-evident, that all men are created equal, that they are endowed by their Creator with certain inalienable Rights, that among these are Life, Liberty, and the pursuit of Happiness† (Declaration of Independence, 1776). Who would imagine that in a country under the blanket such a brilliant, ethical and proud statement of equality, there could be so much dissention about equality? Our nation has interpreted this statement differently since it was written, and still, more than two hundred years later, we are on the road to a truly equal society. This is because racism has its seeds deeply sown into the history of America. Uprooting perceptions of peoples who are dominant and peoples who are inferior has been a long process, from the Emancipation Proclamation to affirmative action. It is important that we stay on this road to equality for all, and keep affirmative action up and running.Affirmative action has its roots in racism as a remedy to it , and racism has its roots all the way back in the colonial and imperial era. Europeans began discovering other continents in the fifteenth century, and with new continents came new ways of making money. Different European countries began to scramble to acquire colonies where they could sell goods, exploit labor, and export slaves and raw materials for cheap prices. Almost all of Africa became colonialized, with different European powers claiming control over sections of Africa, and soon colonialism spread to many new places that were discovered: the Americas, the Middle East, and later Asia and the Pacific Islands. In the process of colonialism, the Europeans were taking advantage of the resour... ...hat happens when we level the playing field? â€Å"No school that has scrapped its affirmative action program has seen minority enrollment return fully to affirmative action levels† (Kranz 26). The ultimate goal is to see minorities represent their population in education and in the work force, and at this point, to attain that goal, it is more ethical to retain the policy of affirmative action than to eliminate it. In the words of Peter Singer, â€Å"In the absence of more promising alternatives it seems worth a try† (51).

Points of Sale Essay

2.1 INTRODUCTION The data collection used as references to gain information during the research conducted. This literature reviews discuss about the information gathered by reading journals and websites. It explains several important terms being used in developing a Student Information Management System. While, project methodology is methods or technique used to complete this project. This chapter covers the related literature and brief analogy of the proposed study which was used as a basis of reference. The theory, concepts, and principles used in analyzing the research were also tackled in the later part of this chapter of the study. The Review of related literature and studies are highly important in appreciating the difference between the past research and the proposed research. Making it useful in formulating more rational explanation in conducting the study and separating concepts that are closely related with both studies. 2.2 LOCAL LITERATURE The proponents included local literatures that would sustain the development of the proposed system. The proponents added reviews, write-ups, readings and studies related to the present study to the related to system determine the similarities and differences of the findings between the past and present studies. The Philippine Science High School Student Information Management System. These Student Information Management Systems are efficient in handling student data, any of which can be utilized by the school registrar of Philippine Science High School. A local variant of a student information system, the Student Record System (SRS) for Philippine Science High School – Central Mindanao Campus (PSHS-CMC), was developed by Taddie Fel L. Dagaerag and company (2002). SRS was designed to assist the registrar of PSHS-CMC but proper attention for the smooth transition from the previous system to the SRS was not given so the system encountered problems, which require major revisions. According to the school former registrar, Ms. Shiela M. Preagido (Registrar PSHS-CMC, year 2005), â€Å"†¦report on grade is not that usable, unless another program will be made that can copy grades from the summary grades sheets,† therefore, rendering the SRS unusable for the present. There are still insufficient services offered by any software solutions company in the Philippines that can provide the same kinds of functionality on a system with lower cost compared to foreign products. Such student information system would cost in the range from 75,000 pesos to 150,000 pesos. Although the Centre is Open Source software, maintenance and system upgrade will cost the school expensively than creating its own system. It is because of the limited capabilities of the schools own system administrators in handling the Centre and the absence of the services offered by the Miller Group in our country. Purchasing or maintaining an expensive student information system is extremely exorbitant. The Bulacan State University Student Information System Technology innovations had influenced man’s work, from data processing, student transactions, research, planning, monitoring and even in medical operation of man’s body is now entrusted to computer technology. Bulacan State University (BSU) as one of the University in San Jose Delmonte Bulacan aims to be the center of excellence in education had recently made changes to some of its existing systems. The student information system of the university is now computerized, and other systems are on its way. This only show that they are coping with the latest technology. The Student Information System of Bulacan State University aims for an accurate, user friendly, efficient system that can help both the student and personnel for fast data processing of enrollment. Engr. Hediki Hashimoto, a Japanese volunteer headed the creation and conceptualization of the system. The information technology faculty from the College of Engineering and Arts and Sciences assisted him. The system that is web based uses PHP programming language with data stored in MySQL is run through the intranet of SSU. A dry-run for this automated student information was done last summer and the first semester of this school year. Offices affected with the automation were the registrar, cashier, accounting, and the Colleges of Education, Engineering, Arts and Sciences, Industrial Technology, Nursing and Graduate Studies. Feedbacks from the students were formulated when the first semester started. Over 75 % of them say that the automation process of enrollment was better compared with the old system. With the good result of the dry run the student information system will be finally implemented this 2nd semester. The Virgen de Guadalupe de Novaliches School Computerized Enrollment, Grading and Sectioning System. This is broader but at the same time more convenient compare to general objective of the current system. As for the specific objectives, the proposed system has the same objectives as the present system but will me using a server that will serve as the storage of the records the registered students, the student’s personal information and the student’s balance if any. This will be more secured and with ease of use as compare to the present system’s logbook and cabinet. Getting, updating and deleting information would also be easier for the proposed system and it will not consume a large amount of space as used by the current system. As for the advantages of the proposed system, the system will make the job of the Registrar easier and more accurate as for the recording of the student’s balance. Instead of making use of a logbook the proposed system will be using an automated storage that will provide proofs such as the previous transactions of the enrollees. With particular to the storage, the proposed system will be less space consuming and more secured for the storage will be automated and will be accessible only by authorized personnel. In the part of the enrollee, the registration process will be faster especially if the enrollee is an old student for the student doesn’t need to fill-up the form anymore instead the Registrar will only require the student’s student number. Moreover teachers will be able to generate reports such as list of students easily. The Ace Adrian Sandoval Registration System can trace what is the standing of the students. It is extremely useful in the school in the way of working processes of enrolling become much easy. The main goal of this type of research is to track student data within the database the data and characteristics about what is being studied. The idea behind this type of research is to study frequencies, validation update of a student’s is highly accurate, and it does not gather the causes behind a situation. An inquiry of the student allows the admin weather the student is on track regarding to the school premises. The Morning Star Academy Foundation Scheduling System relies on their automatic creation of scheduling or timetable of the student; the school is able to update the queries of subject, time room and the availability of the teacher because of the user friendly of the system the admin can automatically understands the environment of the system. 2.3 Foreign Literature The proponents included literatures that would help in the development of the proposed system. The proponents added reviews, write-ups, readings and studies related to the present study to determine the similarities and differences of the findings between the past and present studies.

The Early College High school Student Information System provides schools with information to better understand how well their design and organization are serving students’ needs and resulting in reaching short- and long-term goals, including the earning of two years of college credit by high school graduation. The SIS continues to follow students after they leave early college high school and provides follow-up information to the school on the number of students who continue on to earn a four-year college degree. Schools use the system to monitor the progress of individual or groups of students or classes and to manage information on services and supports provided to students, including tutoring, mentoring, and counseling. The analyses provided by the system support professional development, program planning, and continuous school improvement. The SIS provides solid evidence that helps to sustain and expand funding, policy, and public support for early college high school. In order to obtain access to data on students, Policy Studies Associates contacts schools districts to secure agreement to participate in the SIS. Jobs for the Future works with postsecondary institution and district officials to gain approval for data transfer based on existing policies and requirements. EDSmart works with each institution’s or district’s research and evaluation unit to determine procedures for extracting, transforming, and transmitting district data to the SIS. Personal identity is protected by assigning each student a unique Student Information System number, which is assigned by EDSmart. Only this identifier, not student names or social security numbers, are visible and accessible to users of the SIS. Early college high schools and school districts supplying data on their students are the only ones that have access to individually identifiable student data. Districts are asked to update the data on students, preferably after each term. Information is collected on students enrolled in early college high school (beginning in fall 2002 through the 2008-2009 school year). Aggregated, district data is collected on non-early college counterparts for comparison purposes. Districts report data until the 2008-2009 school year. Postsecondary data collection will continue until 2013, at which point the SIS will be disposed of safely. Data records will be made available to districts for their students. The Early College High School Initiative’s SIS was developed in 2004 to capture and analyze early college high school data. SIS data provide evidence and documentation of student progress and include student demographics, high school and college courses, persistence and grade progression, state assessment results and post-early college enrollment in higher education. The data in the system offer a means for tracking student progress, improving instruction and student support, and helping students obtain a postsecondary degree. Edith Cowan University (ECU) is currently enrolling more than 5, 000 new students, which has been made easier with its Oracle-based online enrolment system. This has allowed ECU to substantially re-design its business processes. The system is known as the Edith Cowan University Web Enrolment System (ECUWES),and replaces traditional hard copy enrolment. According to the coordinator of Admission Support, Kerian Greenaway, the system offers immediacy and convenience of course enrolment via the Internet the technology in use was set up by Oracle in 1998, when ECU moved towards creating an innovative web-based enrolment and administrative system using Oracle database products. New enrolments using ECUWES are managed differently to re-enrolment on ECUWES. New enrolments are processed while the student is with an enrolment assistant, because there is a need to collect HECS and enrolment papers, as well as to familiarize students with the system. In terms of re-enrolment, the student has full control of enrolling in a six-week period, which allows for any small glitches in the system, such as not being able to get online.ECU also previously faced difficulties with managing student enrolment administration, as staffs were distributed across several locations, so there was a desire for improved access and management of student information. Similarly, re-enrolment required students to travel to the University and queue for service from administration staff. Faculties also requested that students enroll by porting enrolment sheets on computer bulletin boards. With ECUWES, students from remote areas and international students enjoy easy enrolment with improved time effectiveness. There have been no major problems, apart from a few power failures, but ECU has back-up plans, such as enrolment assistants taking up all the paperwork and processing the information once back online. Illinois Virtual High School Inquiry This online inquiry gives detailed information on persons that can be contacted with regard to specific field; example is a general program Issues, Technical Problems, Faculty Information and course development. It also gives information about their regional coordinators for participating schools. The website has a login feature where the students can login using their login ID. The online inquiry system of Illinois High School helps the authors to picture out and develop an ideal database structure for the system that will be proposed. The proponents system is similar and is based on some capabilities of the system in this study like the inquiry of courses and login feature for the students. A web-based enrollment system is developed to help both the old and new students, to enroll in a more efficient way without the hassles of waiting long hours just to fill up forms, which sometimes become redundant, or to stand in line and pay at the cashier. It is with the Web-based Enrollment System for VPS that this new style of enrollment may be achieved. This new type of system offers the student with new options for enrolling at VPS. Just by logging on to their website the student may create his new account for the current year he is to be enrolled in. With this, all the student has to do is to fill up certain forms that do not take more than a few minutes to accomplish. Then the records will be stored in the school database for future references. After that the student will be given confirmation that the transaction has been verified and all that the student has to do is visit the school and pay appropriate amount for the current school year. The student may also browse the web site of VPS and he can check his current account. He can also see the list of the school current tuition fee rates. For further enhancement of the site, an on-line payment or e-commerce is highly recommended. This feature for the system could be achieved by collaboration of the school with banks to provide easier payment and a more secure transaction. Posting of grades can also be a great addition to the site. Especially the breakdown of each grade can be seen by the students but with utmost security. Compared to the web-based enrollment system for VPS, the proposed system for CMI would only cover the current students; the student would also be asked to log into his or her account in the website where he/she would be asked to fill up some forms to update the school’s database. A confirmation would then be sent to the student that would inform him/her that the transaction is valid and had been verified. But unlike the system, there would be another option for the mode of payment that the student could choose from namely, on-line payment. AIMS enhances enrollment system of UNO-R Bacolod

Workbook Role of the Health and Social Care Worker

Following extensive consultation with the public, the Department of Health published in 2007 the seven outcomes that people expect from their health and adult social care services. These are – Improved health and emotional well-being; Improved quality of life; Making positive contribution; Increased choice and control; Freedom from discrimination and harassment; Economic well-being; and Maintaining personal dignity and respect The role of the worker can be identified as: Assessment Skills usually the care plan. The aim of the care plan is to assess the needs and risks of the person concerned and make appropriate plans Reviewing/ Evaluating Skills Is a continual process as people's needs and wants change.You will be able to check / measure that the care plan objectives are being met by setting target dates to evaluate what the person has been able to achieve and what needs to be adapted in the care plan and objectives Listening Skills Listening is an important part of communica ting with others. To listen implies that the listener hears, pays attention to and responds to the person. Negotiating Ski ASS The purpose of negotiation is to resolve situations where conflicts have arisen. The aim of a win-win negotiation is to find a solution that is acceptable to both parties and leaves all involved feeling that they have won – in some way – once the negotiation has finished. It is important that the most vocal do not always have their way. Recording Skills Making notes, writing reports, emails, Effective Communication Most communication is non-verbal.People can read visual clues and rely on instinct even if you say the opposite, so if a service user asks you a question, e honest -? your body language will reveal the truth. Team Work Team work is essential in social and health work practice. No one can support someone effectively without others. There is no ‘I' in team Technical Skills These can range from using computers to craft work. Work practice can vary, you need to be flexible and constantly willing to learn Research Skills These skills are increasingly important. You will need them to continually develop your learning Organizational Skills A disorganized person may be creative but will not get very far if they miss the deadline (and visit time) or do not complete the work PersonalPresentation People do judge by first appearances! Always dress appropriately for work and be clean and tidy 4222-206/1 – Understand working relationships in Health and Social Care The working relationships between care staff and the people who they provide care for is critical for their health and wellbeing – Relationships come in very different shapes and sizes. There are relationships between friends, family members, colleagues in outside organizations and the professional relationship between colleagues and service users. The relationship between a worker and a service user should be a supportive professional relations hip. What does this mean?What are the differences between the personal relationships you have with close personal friends & family and those relationships you have with those people you provide care for and other professionals you work with. In some instances the relationships can be quite similar in that they involve helpfulness and working together. In a professional relationship you have a task/goal (I. E. Providing personal care etc. ) that you are working together to complete and achieve. In a personal relationship the ultimate goal is happiness and building that spiritual connection between yourself and your significant other. This is a topic you should discuss with others and relates mainly to what can be seen as the boundaries that you should not cross.The codes of practice for Social Care workers provides a list of statements that describes the standards of professional conduct and practice required for social care workers as they go about their daily work: Social Care work ers must: Protect the rights and promote the interests of service users and careers Strive to establish and maintain the trust and confidence Of service users and careers Promote the independence of service users whilst seeking to ensure hat their behavior does not harm themselves or other people Uphold public trust and confidence in social care services; and Be accountable for the quality of their work and take responsibility for maintaining and improving their knowledge and skills. Developing Relationships The first step in developing effective working relationships is identifying those people who you are dependent on to get your work done and those who are dependent on you. Where you are dependent on each other this is called interdependence. Working on these relationships will give you a big return as there is the likelihood that support provided will be reciprocated.Developing good working relationships relies on a number of things Good effective communication – an abili ty and willingness to talk and to listen with an open mind, what another person says if generally what they believe to be true, if you disagree ask questions to clarify Trust – This is crucial in developing long term relationships, how far do you trust the other person and what will need to happen or not happen for this to be developed? Mutual Expectations – What are the expectations each person has about the relationship, what mutual goals and targets does each person have? 4222-206/2 – Work in ways that are agreed with the employer In order to ensure that your employer is able to deliver the service they have agreed with the service user it is important that you understand what is expected of you. At evidence reference 2 you are asked to review your role and responsibilities and the policies and procedures which you need to operate by.Your employer is expected to: Provide flexible, personalized and responsive service Put people at the centre of everything you do Have high levels of specialist expertise and customer satisfaction Invest time in recruiting the right people for the right jobs Provide extensive staff training and support. If you feel that any Of the above is not in place which is inhibiting you doing your job you should talk to your employer to discuss how improvements can be made. Once set of guidelines that we can follow to guide the way we work is our values: Values guide your work, relationships and life. Values are a person's principles, beliefs or standards by which they live. They would consider these to be priorities for them in their lives, e. G. Pending time with people, being honest, being punctual, being conscientious, assisting people who are in difficulties etc. Everyone has different and attitudes which ill be important to them depending on their background and upbringing. We are not born with values/attitudes but acquire them throughout our childhood, I. E. Through school, friends, family peer group etc. Throu gh our life experiences we are more than likely to change our values. For example, we may have been brought up in a strict religious household taking on those values but as we grow and mature and think about those particular values we may not want them for our lives in the future and take on other values.On the other hand we may prefer to live by those particular values – We all have o make these sorts of choices / decisions for our lives. Enabling service users to make a choice for their lives means putting the Health and Social Care Values into action. As workers everything we do is influenced by our own values. There are a number of Health and Social Care Values detailed below which you must adhere to, if any of your own values conflict with these it is important that you do not allow these to influence how you work. If you have conflicting values take an opportunity to talk to you manager and / or colleagues to find out how these can be reconciled. Health and Social Care Values Value What this means IndividualityNeeds of service users should be tailored specifically for their circumstances / needs / wants / dreams / aspirations, for example, if a person requires a particular meal associated with their beliefs these should be provided. However do not make assumptions always check. Identity Recognize that service users have their own opinions / thoughts / views about things. They will have had many life experiences and these should be acknowledged and valued Rights and Responsibilities Each service user has rights for example to attend their own place of worship, just because it may be ‘inconvenient' is not a reason why We shouldn't meet their rights. They also have rights to change their mind about something.Workers need to encourage them to exercise these rights and encourage responsibility to act within the law and moral responsibilities. Choice There needs to be recognition of the service users ‘right to make their own choices', to exp ress and select what they want and the benefits of this. That everyone is entitled to be given full and thorough information in order to make an ‘informed choice' as to what they want / need. Privacy Every worker needs to understand how to avoid intrusion such as the need for permission to enter the room of a service user and to protect their arsenal space. If visitors arrive at the residential / nursing home they do not have the right to see the resident's room without permission from the service user – it is their home.Inclusion Being part of the mainstream of society is something most of us take for granted. We go to work, look after our families, visit the general practitioner / dentist, use transport, and go to the swimming pool or cinema. Inclusion means enabling and encouraging the service users to do the ordinary everyday things in life, making use of the mainstream services and for them to be fully included in the local community. Independence Recognition that the service user should be encouraged and enabled to do things for themselves. This will enable them to feel involved and continue to practice their skills. The result of this would give them a feeling of being involved.If everything is done for the person they lose their skills, self- confidence and sense of self Dignity Every worker needs to have an understanding of importance Of preserving the service users dignity especially when intimate tasks are being provided. Dignity is closely connected to a person's sense of self-worth. For example, if someone is being assisted to have a bath then the bathroom door should not e left open and as soon as the person is out of the bath, towels need to be put around them so they are not left feeling vulnerable. Respect Every service user of whatever age, disability, race, gender, class, sexual orientation, belief system, etc. Needs to be treated with respect, fairness and dignity, for example, demonstrating to the person that they are very imp ortant and that you value them.This means that they are spoken to as an adult with a kind and thoughtful approach. Working in Partnership It is very important to work in partnership with the service user, their family / friends and with relevant agencies. Every worker needs to take on board the wishes of the person they are supporting, their family / friends and other agencies but the wishes of the service user is the most important. Citizenship The government is committed to enforceable civil rights for everyone in society in order to eradicate discrimination in society. Everyone has a right to a decent education, to grow up to vote, to marry and have a family and to express their opinions with the help and support to do so where necessary. 222-206/3 – Work in partnership with others One of the Health and Social care Values is Working in Partnership' which means that workers need to work in partnership and form effective working relationships with service users, careers, fam ily/friends, advocates, colleagues/ manager and staff from other agencies. ‘Unpaid careers' refers to family members who support a relative. ‘Significant others' means anyone who is significant to the service user they are supporting. Every worker needs to take on board the wishes of the person they are working with, their family and other agencies but the wishes of the person they are supporting should be the most important. It is very important that the service user maintains contact with their friends/ Emily, advocates who may speak on their behalf and significant others. If the service user is in residential/nursing home care/hostel etc. Then regular contact should be encouraged.The service user needs to know they are still part of a family, have friends and have not been abandoned, e. G. The need to belong (Moscow). The family may want to be involved in the support Of the service user, I. E. Personal care such as bathing or taking the person shopping, church etc. It is worth exploring with the service user and family members/friends about how they would wish to be involved and encourage this. Workers should assist the service users in any way possible to maintain these relationships by providing, for instance, a warm welcome and refreshments when visitors arrive etc. This will result in the service users feeling valued, as well as their visitors and also helping to maintain the relationships.
