A human being has been using more and more materials for promotion of its life level year by year. The materials are originated from the Nature. We must think that a human being temporarily borrows them from the Nature. So we should return them in the same form as the origin into the Nature. However, it is impossible because it has been irreversibly changed into different phase. This attributes destruction of the Nature, i.e., pollution of the Nature. For environmental prevention of the Nature from pollution, we should try the entire recycling of materials by returning the used materials in the safe from even if it has a different phase in comparison with the original state. This article proposes the entire recycling of materials lot keeping the EARTH.

In recent years, for the purpose of solving the problem regarding environment protection and resource saving, certain measures and policies have been promoted to establish a reverse supply chains (RSCs) with material flows from collection of used products to reuse the recycled parts in production of products. It is necessary to analyze behaviors of RSC members to determine the optimal operation. This paper discusses a RSC with a retailer and a manufacturer and verifies the behavior strategies of RSC members which may change over time in response to changes parameters related to the recycling promotion activity in RSC. A retailer takes two behaviors: cooperation/non-cooperation in recycling promotion activity. A manufacturer takes two behaviors: monitoring/non-monitoring of behaviors of the retailer. Evolutionary game theory combining the evolutionary theory of Darwin with game theory is adopted to clarify analytically evolutionary outcomes driven by a change in each behavior of RSC members over time. The evolutionary stable strategies (ESSs) for RSC members' behaviors are derived by using the replicator dynamics. The analysis numerically demonstrates how parameters of the recycling promotion activity: (i) sale promotion cost, (ii) monitoring cost, (iii) compensation and (iv) penalty cost affect the judgment of ESSs of behaviors of RSC members.

물 재이용에 대한 인식이 물 재이용 실천의도에 미치는 영향을 검증하였다. 연구결과 물 재이용 절수제품 구매의도에 유의한 영향을 미치는 요인은 물 재이용 실천 필요성 인식, 세면수 재활용 양변기 효과 인지도(p<.01), 공공기관 절수제품 의무설치 인식, 절수제품 의무설치 대상 확대 찬성도, 물 재이용 법률 인지도(p<.05)로 나타났다. 또한 월평균 가구소득이 150만원 이하인 경우, 직업이 전문가 및 관련 종사자와 판매 및 기능 종사자인 경우, 월평균 수도요금이 4만원대 이상인 경우 물 재이용 절수제품 구매의도가 상대적으로 높은 집단 간 차이가 나타났다. 본 연구는 물 재이용에 대한 인식이 물 재이용 실천의도에 미치는 영향을 분석함으로써 물 재이용 실천율을 높이기 위한 물 재이용 정책 추진방향에 시사점을 제공한 데 그 의의가 있다.

최근에 들어 태양광 발전의 시설용량이 급격히 증가되고 기 설치된 태양광 패널의 수명이 다하여 폐기될 모듈의 양이 점점 많아짐에 따라, 이에 대한 처리가 환경문제 해결뿐만 아니라 유가물질의 회수차원에서도 크나큰 관심을 받고 있다. 사용 후 태양광 모듈의 처리 공정은 대부분 알루미늄 프레임의 해체, 강화유리의 분리 회수, 실리콘 웨이퍼에 부착된 에틸렌 비닐 아세테이트(EVA)의 제거 및 태양광 셀 중에 함유된 유가금속의 회수 등으로 구성되어 있다. 전술한 태양광 폐모듈의 리싸이클링 기술들을 치밀하게 검토한 다음, 물질 선별기술을 포함한 효과적인 처리 기술을 제시하였다. 그리고 리싸이클링 산업의 활성화를 위해서 필수적인 생산자 책임제도의 시행을 비롯한 종합적인 의견을 제안하였다.

Around the 1980s, with government's promotion and dissemination policies for FRP (Fiberglass Reinforced Plastics) of the government as a main material of fishing boats, approximately 97% of the entire fishing boats in Korea have utilized FRP until now. Nevertheless, diverse social and environmental issues have emerged due to the susceptibility to fire and the generation of substances detrimental to human health during the construction process of FRP fishing vessels. Especially, the high disposal cost and the limitation of recycling technology in the disposal process of FRP fishing boats have elicited attention to circular economy. This research intended to grasp the management status and problems of disposed FRP fishing boats in Korea, and to assess the level of competitive advantage of FRP fishing boats' recycling technologies of FRP fishing boats based on VRIO (Value, Rarity, Imitability, Organization) analysis through domestic and foreign management policies and related recycling examples. According to the survey of 161 respondents, including the industry, stakeholders and experts related to the collection, treatment and recycling of fisheries wastes, it was revealed that FRP fishing boats' recycling technologies of FRP fishing boats are at the level of 'unused competitive advantage' that satisfied the level of value, rarity and imitability, but not the level of organization.

PURPOSES : The purpose of this study is to analyze the performance life of hot central plant recycling (HCPR) and hot in-place recycling (HIR) pavements applied to the National Highway for the past 20 years and compare it with conventional hot-mix asphalt (HMA) pavement. METHODS : In order to analyze the performance life of recycling asphalt pavements, a comprehensive literature review was conducted to investigate the government law and official system for the use of recycling asphalt pavement in Korea and foreign countries. Next, the application information of using a hot central plant recycling and hot in-place recycling pavements in the national highway is collected from the database of pavement management system (PMS) and then their field condition is visually surveyed. Finally, the performance life of recycling asphalt pavements in the national highway is analyzed and compared with conventional hot-mix asphalt pavement. RESULTS :Institutions are encouraging the promotion of using recycled asphalt pavement through various legal systems in Korea as well as abroad. Based on analysis results for the average performance life of hot central plant recycling pavement applied to the national highway, the average performance life is estimated to be 10.2 years. However, the average performance life of in-place recycling pavement is estimated to be 6.5 years. However, it is expected to increase performance life after the HIR construction system is modified. CONCLUSIONS : Based on the limited data analysis of the performance life of recycled asphalt pavements, HCPR shows similar performance life to conventional asphalt pavement but HIR shows shorter performance life than conventional asphalt pavement. However, it is noted that all performance life data is very limited and it should be monitored and analyzed further.
