The study was designed to heap reduce daily household waste and promote the recycling of society's resources. the focus is on promoting environment-friendly activities and slevating a sense of nature-conscious domestic welfare, as well as providing wars to encourage garbage-savvy shopping, waste disposal by content and recycling. The thesis utilized demographic data obtained from 225 female homemakers and includes results based on frequency, ratio, mean, Duncan's Multiple range Test and Multiple Regression analysis. The main results are as follows: 1. Environmental consciousness appears to be higher than that of the adjustment of purchases to reduce waste and of recycling. Conversely more action seems to be taken on the waste disposal separation established since the launch of the volume-based waste collection fee system than on environmental education. 2. Homemakers with relatively higher environmental consciousness reciprocate with correspondent shopping habits, waste disposal eparation and recycling. Factors that influence daily waste reducing action include environmental consciousness homemaker employment status and the type of residence. 3. Activities reducing daily domestic wastes appear to effect a meaningful variable in explaining a sense of environmental welfare. The more respondents practice related shopping habits, waste disposal separation or recycling the more they recognize their living environment as desirable.

We have investigated the possibility of recycling of an organic material that is wasted during thermal evaporation. To this end, we have collected a wasted organic material (N,N'-diphenly-N,N'-bis(1,1'-biphenyl)-4,4'-diamine(NPB)) from a vacuum chamber, purified it by recrystallization, and fabricated bilayer organic light-emitting diodes (OLEDs) with the recycled NPB. It is found that the surface roughness of thin films coated with the purified NPB is much enhanced. OLEDs fabricated by thermal evaporation of the purified NPB show lower device efficiency than OLEDs with the original NPB. However, the power efficiency of OLED fabricated by spin coating of the purified NPB is comparable with that of OLED with the original NPB. Therefore, such a recycling method by recrystallization would be more suitable for solution-processed OLEDs.

In this study, Life Cycle Assessment(LCA) was applied to the production processes of waste cooking oil recycling products. Recycling products as defined in the Law of Saving of Resources and Recycling Promotion are biodiesel and soap. Weighting result of biodiesel production process showed that the most significant impact potential was abiotic resource depletion(84.17%) followed by global warming(13.93%). In the case of the soap, the most significant impact potential was also abiotic resource depletion(58.59%) followed by global warming(33.71%). In terms of the whole system of the biodiesel production process, methanol showed the largest environmental impact potential(87.35%). While in the case of the soap, sodium chloride showed the largest environmental impact potential(99.99%). This study suggests that there should be improvement of the methanol recovery system in the biodiesel production process and also appropriate use of the major environmental impact materials in both processes.

The purpose of this study is to understand the Korean consumers' socially responsible clothing acquisition behavior respond to altruistic and economic incentives toward recycling of clothing and the relations between demographic variables and acquisition behavior. Data were collected from the adult females residing in Seoul. Judgement Sampling were performed twice and total 549 sets of answers were used for final analysis. The results are as follows : First the consumers of favoring altruistic and economic incentive prefer to acquire clothing with free cost and the consumers favoring altruistic incentive tend to acquire clothing through unknown persons,. Second the analysis of relationship between the attitude toward recycling incentives and the demographic variables shows that the consumers with relatively higher education have strong will for recycling by altruistic incentive. Third the analysis of relationship between acquisition behavior and the demographic variables shows that consumers with relatively lower education normally acquire clothing from unknown persons and from acquaintance. In addition married persons tend to acquire clothing at free of cost.

This study was conducted as a preliminary step to establish a model for the practical application of environmental education related to food wastes collected from elementary school foodservices. Methods of treatment and present recycling status of food wastes in elementary schools in Kyonggido were surveyed. The consciousness of dieticians who have been serving for elementary school foodservices was also analyzed through the survey questions concerning environmental education for the reduction and recycling of food wastes. The results derived from this survey were as follows: The major portion of food wastes from elementary school foodservices was constituted with vegetables and soup, and an average amount of food wastes per day was highest in June and July. Therefore environmental education related to reduction of wastes was needed in the first semester of school terms, and the possible reduction of food wastes achieved through the proper planning of school foodservice menu was also needed. In most cases food wastes were collected and treated by animal growing farmers or composted by machines in school. In operating composting machines microorganism inoculant was mostly used but dieticians pointed out the problem of a nasty odor, insects, and high energy consumption. This situation means it has not been operated efficiently and suggests an efficiency problem of machine composting in elementary schools because composting itself is based on the aerobic digestion and high temperature fermentation which kills insects and harmful microorganisms. Elementary school dieticians in Kyonggido were aware that food wastes cause main pollution problem, and that food wastes are valuable resources which can be recycled, and recycling of food wastes is inevitable. But more than half of the schools surveyed have not been reused food wastes in school, so a proper model for recycling and reuse of food wastes in school grounds was thought to be needed. Environmental education programs related to food wastes have not been peformed in more than half of the schools surveyed. It was concluded that the following three plans will be helpful to reduce school food wastes. First, environmental education should be enforced, second, teachers' and dieticians' intensive teaching concerning food wastes should be needed, and finally establishment of a model for recycling and reuse of food wastes in school grounds and its application to environmental education would offer a valuable field experience to school students.
