  • This study was carried out to investigate and analyze the citizen's attitude for the issue of the municipal solid wastes in Miryang city. The waste generation rate was decreased by 56% compared with 1991, and 71.8% of generated wastes were treated by landfill method. 61.6% among respondents were contacted waste problem by TV and the majority of respondents felt seriousness of food-waste problem. The majority of people felt that waste discharge decreased after "volume-base charge system" and 71% of total respondents were burdened down with use of volume-base charge envelope. The greater part of citizens answered that they experienced damage due to wastes and satisfied with the collection system but they recognized the necessity of the establishment of collection system and increase of cleaners must be nessary.

  • Environmental issue is one of the key factors to industry area using fossil fuels, because it accelerates the global warming. So it is supposed to reduce greenhouse gases around the developed nations of the world at times go. This issue is especially for the power industry. Under this background, CHP system that consists of Distributed Energy Resources (DER) system, such as natural power system (wind, solar) and fuel-cell, co-generation, also known as CHP (Combined heat and power), has been developed greatly during the last 10 years. This paper adopts optimal model using GAMS to develop methods for conducting an integrated assessment of MicroGrid system.

  • This study aims at evaluating the environmental impacts stemmed from the End-of-Life Vehicle(ELV) treatment systems in Korea, using Life Cycle Assessment(LCA) method. In this study, both environmental burden from the ELV dismantling process & recycling processes and environmental benefit which were derived from the avoided environmental impacts by substituting recycled materials for virgin materials were considered. First of all, the key issues which were defined as the environmental aspects that account for more than $1\%$ out of the total environmental impacts were identified from the Life Cycle Impact Assessment(LCIA). $CO_2$, crude oil, natural gas, coal, etc. were found out to be the key issue parameters. From the LCI Analysis and LCIA studies, it was shown that the significant environmental aspects were related with the recycling process of ferro scrap, the shredding process of compressed car bodies and the dismantling process of end-of-life engines. In particular, the recycling process of ferro scrap has the most significant effects on the environmental impacts of the ELV treatment systems. Based on these results, it is recommended to improve the recycling process of ferro scrap in order to make the ELV treatment systems more environmentally sound.

  • The purpose of this research is to study motivation of freshmen in Environmental Education Department for choosing their major, and their environmental awareness in overall. The subject for this research is twenty freshmen, majoring Environmental Education at Korea National University of Education in 2007, and methods of the research include survey through questionnaires, reviewing literature of the field, and conference with experts in Environmental Education. After the research, six freshmen's motivation for choosing Environmental Education as their major changed positively. Awareness of the environment in residential area changed somewhat negatively, while awareness of the nation's overall environment changed positively. Subjects' recognition for the need of Environmental Education was generally negative in both the first and second surveys whereas that of sustainable society changed more remarkably throughout the surveys. Most subject thought that the most important issue Environmental teachers should teach is proper attitudes towards and reasonable actions for the environment.

  • In this study, the environmental consciousness of Daegu citizen on conservation planning considering the regional characteristics was investigated. Data were collected throughout a survey and 1400 people were selected using a stratified sampling method based on populations of Daegu administration district. Results wee followings; First, the levels of environmental consciousness were different dependent on districts' characteristics. Second, poor awareness on Daegu Agenda 21 (Clear and Green Daegu 21) were shown. Daegu Agenda 21 is the action plan for the sustainable environmental conservation activities of the City of Daegu. Third, waste was the most serious environmental problems of Daegu, air quality was second worst, and third was river water quality from the survey, but differentiated awareness was shown dependent on regional spatial factors and pollution emission factors. Last, a public environmental education was the most important issue to make invigorations and progress for future environmental policy.

  • Differences in risk perception on major environmental issues between general public and environmental experts were investigated in this study. Questionnaire surveys were conducted to samples from general public and environmental experts during March and April, 2000. Total number of responses was 1,126 including 773 persons from general public and 353 experts. Risk perceptions on 26 environmental issues were related with the need to regulate each issue, controllability, experience, political views, interest in environmental problem, satisfaction of environment, severity of environmental pollution. There was statistically significant difference in risk perceptions between general public and experts. Overall, general public was likely to perceive risks associated with environmental problem, as well as social need to regulate these problems more than experts. The issues with high risk perception and need to regulate were 'automobile exhaust', 'industrial air pollution', ocean pollution by industrial waste and oil exhaust', 'air pollution by chemicals', 'surface water pollution by waste from household', 'industrial and hospital waste', 'surface water pollution by pesticide'and'sewage and food waste'. Consequently, it seems necessary to manage these issues, prior to others.

  • We easily witness that environmental issue is very critical point to affluence upon a restructuring the value system of human being. Therefore it is obvious that this issue affluence upon the field of design as well. The most important feature of environmental issue is 'wholeness' in itself. It means that we have to approach and to solve it as a whole. Also, design is to be done at the same way. The creative professionalism of design could provide a clue to solve the problem, but designer are tend to seek a solution in a just partial way such as recycling and packaging. But those attitude may cause more problems and spread it futhermore. Therefore this study is analysis some recognitive turning factors in order to solve the problems as a whole, and to suggest a appropriate methods according to such a view point. Even internal retrospect in design itself or external demand from the other, If we look away this issue, the real purpose of design, contributing for society, should be diluted by ourselves.

  • Clean plate education program was applied to change students' perception on food waste in the dormitory cafeteria of T campus G university that is located in Tongyeong, in which 408 students joined the program. From survey and food waste monitoring, it was found that clean plate education program was effective to change students' perception as well as action. Half students (50.5%) answered that their eating habit changed, and among them 30.1 % students left a little food on the plate and 13.1% students left no food behind. Many students become aware of the seriousness of food waste issue (84.5%), and 44.2% students were trying to reduce leftover. Food waste generation in cafeteria was 341.9, 576.1, 344.3g/capita/day in 2005, 2007 and 2008, respectively. And this shows that food waste generations were much less than national average data except 2007. Therefore we could conclude that clean plate education program was satisfactory to change students' perception on food and to change their action, and it could be an excellent new approach to resolve a social issue caused by food waste. In order to reduce food waste generation at dormitory cafeteria, food taste and diet should be improved and students' eating habits also should be changed. For this, a practical program like clean plate education should be organized.
