The purpose of this study is to prepare the way for the prevention and improvement of the ocean environment pollution and destruction by researching and analyzing the degree of interests in the ocean environment which the students of seaside vocational high schools have. The concerns of this study are as follows: 1. The vocational high school students in the seaside cities of Busan and Pohang have recognized that the ocean is the object of the highest potential of development and that through the degree of their recognition that they should better preserve the ocean environment prior to a high degree of local seaside development. 2. Although they have recognized that the ocean environment has a great influence on the life of people, their interests in the environment is low. Also, it is shown that they get their knowledge and information through TV. 3. They've understood that the main factor of ocean contamination concerns the home and the causes of ocean contamination are sewage and waste material from daily life. Moreover, their answers reveal that they believe that they should participate in a sanitization activity for the ocean environment voluntarily and put trash into nearby trash cans as opposed to inconsiderately throwing away trash on the beach. 4. Their answers also show that they recognize the elements that can best preserve the ocean environment start at home and with government, and school services through experience activities are the most effective for the education of the ocean environment.

In this paper, a Home Mess-Cleanup Robot(HMR), which has a practical function of the automatic mess-cleanup, is developed. The vacuum-cleaner had made the burden of house chore lighten but the operation labour of a vacuum-cleaner had been so severe. Recently, the cleaning robot was producted to perfectly solve the cleaning labour of a house but it also was not successful because it still had a problem of mess-cleaning, which was the clean-up of big trash and the arrangement of newspapers, clothes, etc. The cleaning robot is to just vacuum dust and small trash but has no function to arrange and take away before the automatic vacuum-cleaning. For this reason, the market for the cleaning robot is not yet built up. So, we need a design method and technological algorithm of new automatic machine to solve the problem of mess-cleanup in house. It needs functions of agile automatic navigation, novel manipulation system for mess-cleanup. The automatic navigation system has to be controlled for the full scanning of living room, to recognize the absolute position and orientation of the self, the precise tracking of the desired path, and to distinguish the mess object to clean-up from obstacle object to just avoid. The manipulator, which is not needed in the vacuum-cleaning robot, must have the functions, how to distinguish big trash to clean from mess objects to arrange, how to grasp in according to the form of mess objects, how to move to the destination in according to mess objects and arrange them. We use the RFID system to solve the problems in this paper and propose the reading algorithm of RFID tags installed in indoor objects and environments. Then, it should be an intelligent system so that the mess cleaning task can be autonomously performed in a wide variety of situations and environments. It needs to also has the entertainment functions for the good communication between the human and HMR. Finally, the good performance of the designed HMR is confirmed through the results of the mess clean-up and arrangement.

Many critics on William Faulkner's As I Lay Dying have read Addie Bundren as the disrupter of patriarchal power. By raising a question about the usefulness of language, which is the symbolic power of patriarchy and having an affair with the preacher Whitfield outside her wedlock, Addie directly challenges patriarchal power. From a quite different vantage point, however, we can read Addie as the faithful protector of the norm of whiteness in the South in light of the social hierarchy. As a former school teacher, Addie is from middle class before her marriage. By her marriage to Anse, who is a lower-class white, Addie has class anxiety that her social status in the stratum of whiteness could be degraded from a middle to a lower-class white, "white trash," which means that she is not white enough to be considered as the normative whiteness. Especially, Addie's anxiety increases due to the fact that her lazy husband is reluctant to work and relies on her neighbors, causing her family to be entrapped at the bottom in the stratum of whiteness. Therefore, she decides to take revenge on her husband after giving birth to her second child Darl by asking Anse to bury her dead body in her familial burial site in Jefferson. By rendering her family to suffer the hardship during her funeral procession, not only does she succeed in taking revenge on Anse on the surface, she regains her social status as a middle-class white by being buried in Jefferson fundamentally.

Product design should reflect environment and experience of use in consideration of product's role as well as roles in life. In doing so, it is expected to realize interaction between product's role and users. Therefore, design of a recycling bin should also consider not only colors, shape, or materials but also process and experience of use. This study was conducted targeting public recycling bins in Beijing. As for the study method, first concept of a recycling bin was defined while specifying significance of recycling in Beijing City. Also, advanced research on recycling related policies that are currently being promoted was carried out. Second, current status of recycling in Beijing and problems of recycling bins were analyzed through on-campus survey. Lastly, users' psychological demand on a recycling bin was assessed and analyzed to suggest developmental direction of recycling bin design in the future.

Municipal and sanitary landfills can pose environmental problems due to leachate, landfill gas md unstable geotechnical properties. Most governmental bodies delay the correction of landfill problems or landfill replacement until a crises stage is reached. The replacement of a landfill is often made difficult due to costly regulatory controls, public opposition to siting and the high cost of closure for the previous landfill unit. Solutions to extending landfill life and capacity Involve waste minimization by recycling, refuse compaction and waste-to-energy incineration. Incineration can reduce the volume of refuse by 50-95%. The largest installed bases of municipal waste Incinerators are located in Japan and the U.S. The volume of waste contained in a landfill can be estimated by load count tabulations, weight-and-volume measurements or a material balance analysis based on the trash profile of user categories. for an existing landfill, core samples may be collected and analyzed for use in a material balance analysis. Newly generated refuse contains approximately 50% of the heating value of coal. However, landfill properties vary significantly due to the waste profile of the contributors and biodegradation due to time and weathering. The volume of the Nanji-do landfill

The purpose of this study was to survey the trends of waste products in schools, its gathering and disposal, identification of problems and to analyze its disposal. Moreover, this study was aimed at basic suggestions about the establishment and plans of waste environmental education. 98 public primary and secondary schools were surveyed in Seoul during the month of March and April, 1991. Information was collected from each educational association by random sampling. Questionaries were used for this survey. To understand the disposal status of school waste and its reforms, this study surveyed the amount of waste by products, their origin and analyzed the disposal by type, one number of schools and teachers involved. The dump sited and disposal methods of school waste, its problems, and the status of school waste educations were researched, and ideal disposal methods and plans for waste education were suggested. The results were as follows. 1. The School's trash was produced by followings: paper, vinyle plastics, food, woods, metals, ceramics, glass, bottles, and ash from the heating system. The biggest cause of the school's waste as shown by the survey was a lack of environmental awareness(39.8%). The second biggest was the use of a one time use of disposable paper products(27.6%). 2. Waste collection by different grade levels were proven to be important but as you move from elementary to high school, the waste collecting operation decreased, in this connection between the students and waste collection itself it was significant on the other hand the teachers were not working as significant variables. 3. Of the school that collected waste 69.5 percent of the schools separately grouped common waste and recyclable waste. 25 schools(42.4%) received improvement on their environmental awareness of trash collection through this method. 4. From the number of disposal sites in surveyed schools, it was determined that the education of the necessity for separation of waste was performed in vain and accordingly the should require a real education in the future. 5. Regarding the method of disposal of waste the survey indicated that the #1 method of disposal was partial burning and the remains carried to a dump site by others(35,7%). In elementary schools the entire waste was taken by individuals to a dump site (33.3%). In high schools partial burning and then transported by individuals #1 in our survey(50%). 6. Relative to the problem of the treatment to waste, the emission of smoke from the burning was considered to be the #1 priority in our survey (62.3%) the problem of trash collection being delayed was 52.1%(1in our survey). 7. The present situation of environmental education of waste us lacking. Under present circumstances, the practice of public announcements for improvement and waste-paper collection has been going on vigorously but lacking in education as to the preparation of compositions for students the themes of public exhibitions, the organizing of voluntary associations should be part of the education system to reinforce student's awareness of proper waste disposal. 8. The most economical alternative for disposal was recycling usable waste or combustible material through a variety of education we can therefore educate students bring this education to their homes public servants will also be able to benefit in the waste disposal process with proper education. In conclusion we should intensify the systemical organization and the education of our waste disposal for a better environment.

Concerns on environmental issues and global warming are increasing worldwide. Environmental regulations such as Tokyo Protocol, RoHS, WEEE are also getting harder and harder and used as trade barriers. Different from other manufacturing industries, information and communication industry is basically environment friendly-low emission of harmful materials and little consumption of energy. But information and communication industry can contribute to world environment by recycle articles in disuse and properly process discarded trash. Furthermore, by using more renewable energy, it can reduce the $CO_2$ emission, one of the major the green house gas.

Used motor oil contains pollutants, including organic chemicals and meta]s. When disposed of improperly - in the trash, on the ground or in a sewer system - the pollutants may reach rivers, lakes or the ground water. Thus, all the waste oil products such as waste motor oil, waste oil container, and waste oil filter should be collected and transported for recycling or disposal by waste oil regulations. Because waste oil container is a valuable resource, waste oil containers can be reused, cleaned, buried, and burned for recycling processes. This paper presents the integrated management system that may increase the efficiency and productivity for collecting and reprocessing waste oil containers such as steel can and plastic container. The integrated management system consists of collection and transportation process management system and confirmation and certification process management system for waste oil containers.
