In general, industrial production involves large amounts of harmful by-product, causing serious pollution and ecological risk. Eco-efficiency, which indicates how efficient the economic activity is by considering both the environmental risks and economic performance, is a new concept for economic sustainability analysis and quantitative ecological risk analysis. Data envelopment analysis (DEA) has been widely used to examine eco-efficiency in recent years. Whereas traditional DEA models such as CCR and BCC model neglect undesirable outputs, this paper adopts a stochastic undesirable-output DEA model to measure the eco-efficiency of each province of China and Korea. The results indicate that whereas the eco-efficiency of the eastern region was the highest, that of the western region was the lowest. The reason may come from the negative external dis-economies of environment. And thus the governmental efforts for outreach on the underdeveloped regions should be promoted.

It pollute the earth environment with systematic industrialization. Also the congestion of cities that ignore ecosystem threaten habitation environment of human. For ESSD make progress to many researches internal and external. However we don't develop model for internal environment, research evaluation of ecological polis for this. The present research put in operation that make up question experts. In the event many people know necessity of ecological development. But It point out reality with many phases. One side we need to educate, publicize about environment. make good model and cultivate process.

인류가 지속적인 삶을 유지하려면 다양한 생물을 보전해야 한다. 원론적인 주장으로 받아들여지던 생물다양성이 지난 2010년 나고야 의정서가 채택되면서 큰 변화를 보이고 있다. 생물다양성은 이제 경제적인 측면에서도 결코 간과할 수 없는 이슈가 되고 있다. 여기서는 LG경제연구원 도은진 연구위원의 '온실가스 이을 환경이슈, 생물다양성' 보고서를 통해 생물다양성이 무엇인지, 앞으로 기업에 어떤 변화를 가져오게 될지 살펴본다.

In this paper, we propose a novel on-demand multicasting algorithm, 'Durable Distance Vector Multicasting(DDVM),' for Mobile Ad hoc Network(MANET). DDVM has a more efficient routing-control complexity than Link State Routing(LSR) and with the smaller complexity, DDVM provides a high delivery ratio for MANET with high mobility by adapting to dynamic topological changes. This is achieved by adding 'combined path durability' statistic into the routing-control information of Distance Vector Routing(DVR). The routing-path duration statistic is computed in a fully distributed manlier at each node in the network based on only local information from neighbour nodes. We show by simulation studies the effectiveness of DDVM compared with On-demand Multicast Routing Protocol(ODMRP).

In this paper, economic performance was measured through portfolio analysis for environmentally friendly companies from September 2004 to September 2005. By using portfolio analysis, rate of revenue for environmentally friendly company is twelve to seven teen percent higher than the KOSPI, and KOSPI200 based companies. Except medical and pharmatical industry, environmentally friendly companies had shown low risk and high returns of revenue for banking and financing, chemical and electronic industry. As SRI fund is emerging as a important guideline in recent years, valuation of a cooperate will be very important tool for the financing business area in the future.

오늘날 우리사회는 환경변화와 기후 위기 가속화로 인하여 삶의 질 악화는 물론 인류 생존까지도 걱정해야 시기에 이르렀는데, 이러한 변화의 주범인 온실가스의 75%가 도시에서 발생되고 있다(Global Sustainable Development Repor, 2019), 이에 국제 사회는 도시 중심의 녹색 전환 정책 추진 중인데, 우리나라는 2017년부터 '도시재생뉴딜사업'을 추진하고 있다. 이에 본 연구는 지자체가 주도적으로 환경성과 창출 방안을 마련, 도시의 지속가능성 높이는데 일조하고자 탄소중립 선도 도시 사례와 도시재생의 문제점을 살펴봄으로써 도심 내 과밀화 문제와 탄소배출 해결 방안을 제시하였다. 당초 '도시재생뉴딜' 사업은 도시의 다양한 니즈를 충족시키기 위하여 시작되었으나, 최근에는 도시 노후화와 탄소배출 문제에 대응하기 위하여 '그린도시', '친환경 도시'를 지향하고 있다. 그러나 이를 뒷받침할 법·제도의 제·개정 및 이를 바라보는 이해관계자의 시각 전환이 이루어지지 않아 크고 작은 많은 문제점이 발생하고 있다. 도시재생의 첫 번째 문제점은 정책지원의 30% 이상이 일반근린형에 집중됨에 따라 주거형 도시재생 양상을 띄고 있다는 점이다. 이는 임기가 제한된 지자체장이 가시적인 성과를 위하여 도시 내 인프라 확충에 집중한 결과로 지속가능한 도시재생을 저하시키는 요인이 되고 있다. 두 번째, 도시재생 뉴딜사업이 계획수립과정에서 지속가능성에 대한 검토와 환경성 평가에 대한 고려 부족으로 기후 위기 대응에 미흡한 실정이다. 노후 도시의 주거 과밀화 문제를 해결하고 효과적인 도시 탄소 감축을 위하여 건물 - 마을 - 도시 등 여러 공간 단위의 온실가스 배출량 감축 전략 수립이 필요하다. 세 번째, 치·이수 위주의 도시재생 뉴딜사업으로 탄소 중립 대책이 미흡하다. 대응 방안으로는 자원의 관점에서 물 소비 감소 촉진 및 재생에너지 증가 전략이 필요하다.

This study conducted a regulatory impact analysis regarding the introduction of the Korean version of REACH(Registration, Evaluation and Authorization of Chemicals). The direct cost of the Korean REACH is estimated at a total of 101 billion Korean won over the 11 year period. The cost includes pre-registration, testing, registration, Chemical Safety Assessment(CSA) and Chemical Safety Report(CSR), evaluation, and the authorization costs of 15,223 chemical substances produced and imported more than 1 ton per year in Korea in 2006. With regard to the benefit, the only public health benefit is included in the estimation. Based on the available foreign and domestic data, this study estimated that the economic values of public health benefits are in the range of 33.2~138.6 billion Korean won if only the savings of the National Health Expenditures are considered and it reaches 203.9~1,640.3 billion Korean won if the willingness to pay(WTP) for disease prevention is included. This study proved that the Korean REACH passed the cost/benefit criteria. The benefit-cost ratio of the Korean REACH, however, is estimated to be lower than its EU counterpart. Thus it is suggested that a rigorous study to reduce the costs to industry be required before the Korean government introduces the Korean REACH.

In accordance with the environmental changes that surrounds the port, there seems to be a trend of increasing interest in a sustainable development and operation of port. Considering that sustainability assessment utilizing Triple Bottome Line(TBL) has been conducted actively in various fields of research, it is essential to evaluate port sustainability including not only economic aspect but also social as well as environmental ones. In this regard, this study aims to measure the relative importance of port sustainability index using AHP. Moreover, sustainability of Korean four major ports has been tested by adopting the newly developed index in this study. From the results, it can be concluded that in addition to securing high value cargoes, increasing efficiency of port operation and infrastructure together with capital investment are essential. Growth harmonized with surrounding area of port and environment-friendly port operation should not be disregarded.

선진국은 현대전 및 미래전에서 통신/전자장비의 생존성이 전쟁승패의 주요 요소임을 인식하고 장비 획득규정 및 관련 군사규격을 보완하며, 취약성 시험과 EMP, EMR을 비롯한 각종 전자환경시험 능력을 강화하고 있으며, 첨단무기체계 개발에 따른 전자시험평가 능력을 지속적으로 발전시키고 있다. 하지만 우리의 경우 현대전에서 그 중요성이 부각되고 있는 취약성시험과 전자환경 시험평가 능력은 매우 미흡한 수준이다.
