This study has an aim to construct a reference frame to analyze the appropriateness of environmental education(EE) materials of elementary schools, and to search the basic direction of the scheme for analysis. In addition, this study has an aim to induce what the results of this analysis suggests for the development and reconstruction of EE materials. It was analyzed how truly EE materials reflected contents selected as an analysis scheme, after grasping practical use and features of textbooks, audio-visual materials, and a web-site that are typical materials in EE of elementary schools. The results in textbook analysis were that there were a human-centered environmentalism in the EE unit ("Environmentally Sound National Development", 5th Grade) of Social Studies. The result in analysis of audio-visual materials "Environmental Warrior, Zentaforce" of EBS, were that there are unhealthy environmentalism in that material. In other words, technology itself is considered as a almighty means to solve environmental problems. Finally, the result in web-site analysis were that the "Environmental Class" of Ministry of Environment did not have sound environmentalism. The above result of study shows us that the most important thing in developing and using the environmental education materials is to have sound environmental values and EE perspective, to evaluate EE material with various point of view, to judge its result, and to use it.

The animal industry must be environmentally sound to ensure its long-term sustainable growth. Livestock wastes mostly manure, can be a valuable resource as well as a potential hazard to environment. The first option of manure management is developing an 'environmentally sound' feeding program and feeds so there are less excreted nutrients that need to be managed. Once the manure is produced it can be best utilized as a fertilizer of a soil conditioner. In many countries the amount of manure that can be spread on land depends on the nutrient requirements of the crop being grown. The laws specify maximum application rates and not animal stocking rates. Farmer who reduce the N and P component of manure can release pressure on the environment without having to reduce the number of animals. There are alternative system for housing and manure treatment which generate manure that are easier to handle and have less pollutants or more economic value. Treated animal waste may also be used as a feedstuff or fuel source. Most of the options of waste management result in increased costs to implement. It is necessary to assess the economics in order to find an acceptable compromise between the increased costs and the benefit to the environment. Animal welfare is also becoming more and more of an issue and it will lead to systems where animals are kept in less confined environment. The new system will have a great impact in the waste management system in the future.

Theses days, there are 3 prerequisites for dam building in Korea: First one is how to build the dam safe and stable from the technical points of view. Second one is how to design and construct the dam environmentally sound with the minimum change of the surrounding area of the dam site. Third one is how to activate the local economy of the surrounding area of the dam site in order to make the dam construction sustainable from the social and economical points of view. As far as technical aspects far dam building, there are hardly any problems in dam design and construction in our country. However, there are a little difficulty according to the location of the dam site. In order to fulfill the second option it is believed that a lot of effort should be made to accomplish the second task not only because that fairly large area shall be inundated with water after impounding but also because that ecological environments shall be changed due to change of water environment. Therefore, thoughtful investigation and assessment of the environmental features of the local regions have to be preceded before starting of the dam building. In order to overcome these difficulties Hantan river dam has been declared as an Eco-dam with 3 strategies and 9 activities plan at the design stage after sufficient consideration of the local identities of these region and coupled national plans for surrounding areas. Finally, Eco-tourism with the several coupled network-wise touristic courses, namely PERTH model, has been proposed after thorough analysis of the local identities by the Jahari window to make local economy being activated. Detailed descriptions for 3 strategies and 9 activities plan for declaration of Eco-dam and proposal of Eco-tourism with the network-wise touristic courses will be mentioned in the main content.

As the population grows, the importance of the fishery industry continues to rise. It is therefore vital to support and promote sustainable fishery industry. However, the fishery production has been declining, mainly due to overdevelopment and depletion in fishery resources and stricter limits on development limits caused by growing concerns over the marine environment and ecology. Recently, international activities related to marine environmental and its ecosystems conservation, have been vigorously pursued. The United Nations Convention on The Law of The Sea has stipulated the protection and conservation of the marine environment, and the implementation of fishery resources development, made in harmony with the environment and fishery resources and based upon scientific findings and principles has become important. Accordingly, fishery industry must pay thorough attention to marine ecological and environmental problems and its international fisheries regime. Fisheries development can affect fishery resources, their environment and ecosystems. Adverse ecological effects resulting from fishery resources development practices in general include overdevelopment and incidental development of non target species, physical degradation of seabed habitants and degraduation of water quality. It has now become more important than ever to build up fishery resources development while achieving the conservation of biodiversity and the marine environment, as well as the restoration of destroyed ecosystems. To maintain fishery industry, it is necessary to develop bioeconomic fishery production system and industry policies for the ESSD(environmentally sound and sustainable development) given that maintenance of a favourable marine environment will ensure the fishery resources productivity. These bioeconomic system and policies are necessary to ensure the sustainability and viability of the fishery industry under ESSD fisheries concepts.

우리나라는 국적외항상선의 수가 2006년 1월 기준으로 546척, 13,716,733 G/T에 이르는 세계 제 8위의 해운강국이다. 선박은 건조시로부터 25년에서 30년 정도 운항하면 그 수명을 다해 다른 용도로 변경되어야한다. 수명이 다 된 노후 선박의 처리방법으로 재활용이 가장 나은 방범으로 대두되고 있으나 여러 가지 환경적 규제와 노동 규제에 의해 현재 선진국에서는 거의 이루어지지가 않고 비교적 법규제가 느슨한 개발도상국으로 옮겨지고 있으나 국제적으로는 선박도 하나의 폐기물로 보고 국가간 이동을 금지하는 추세이다. 본 연구에서는 선박해체산업현장의 열악한 작업환경과 환경피해의 심각성 해결을 위한 국제적인 동향을 알아보고자 하였나. IMO, UNEP, ILO 에서는 선박의 해체 작업에 참여하는 작업자들의 건강과 안전을 보호 하고 환경오염을 방지하기 위하여 선박내의 유해물질을 목록화하여 유해물질을 관리하도록 하는 방안을 마련하고 있으며, 선박의 재활용과 관련한 바젤협약, IMO Guideline, ILO Guideline, IMO Convention Draft를 통해 세계적인 추세를 알아보았다.

Recently, endocnne dIsruptors have been known as one of the most harrnful chemical material. The purpose of this study is to investigate the cogintion and behavoor of milddle school students on the endocrine disruptors. To achieve this goal, survey research was conducted. Data were collected from 531 first and third-grade students in Suwon city. The main results of this study are summarized as follows FIrst, the mam source of information on the endocrine disruptors was mass media such as TV. This means environmental education in school is needed and mass media can be a very important tool for education. Secondly, as grades become higher, more students had knowledge on the endocrine disruptors. The difference between boys and girls was not significant. Thirdly, most students recognized endocrine disruptors as a dangerous material. However, they had an optimistic view on the possibility of resolving the environmental problems using science and technology in the future. Lastly, the scores of environmentally sound behavior was not highly correlated to those of knowledge. This means that in current environmental education system, more knowledge on the endocrine disruptors do not ensure more environmentally-correct behavior. These survey results show that environmental education on the endocrine disruptors should be constructed to induce correct behavior. That is, environmental education from now on has to be conducted to change the behavior of student as well as to increase knowledge.

This study was performed to identify the roles of residents for the environmentally sound and sustainable development, taco-polis(kologisches Bauen), eco-village and Symbiotic Housing. These buildings will achieve energy efficiency through design strategies such as passive solar heating system, natural cooling and day lighting. Their infrastructure will feature parking on the periphery, extensive pedestrian paths, outdoor ground lights that preserve stellar visibility, and environmentally sensitive technologies such as low writer use fixtures. And they will restore biodiversity while protecting the wildlife, wetlands, forests, soil, air and water. Their houses wile be designed to support home-based occupations, offering high-speed Internet access and other options to promote a localized, sustainable economy. To support and encourage the evolution of sustainable settlements, it is necessary to prepare constructing the physical facilities and the social functions relating with residents. The roles of residents are important to provide a high Quality lifestyle and to integrate a supportive social environment with a low-impact way of life. This study concluded the four main roles of residents for the sustainable of Eco-polis and Ecovillage. 1. Residents assist transition towards a sustainable society as eco-conscious consumers in the planning stage. 2. Residents live in a ecological way for the sustainable ecovillage. 3. Residents exchange information and education for increasing the community glue as a communication network. 4. Residents support and transmit their cultural vitality and tradition for the next generation. So, users are expected to encourage resident's participation in the planning, design, ongoing management and maintenance of the sustainable ecovillage.
