The world has faced with various environmental problems such as climatic change, global pollution, and depletion of natural resources. Conventional economic development continues not only to intensify the magnitude of the problems but also to damage growth potential of future generations. Therefore, recent manufacturers are highly required to accommodate themselves to sustainable development that aims at preventing the loss to the future generations. Moreover, the manufacturers are under heavy pressure from various environmental regulations. This paper proposes green bill of material (Green-BOM) which conforms to the environmental regulations to restructure eco-friendly manufacturing system. Green-BOM is useful for managing green product and process information to satisfy several environmental regulations by recording energy consumption, recycle rate, volatile organic compounds (VOCs), substance information, and so on.

In recent years there has been a growing recognition that presenting principally environmental issues in environmental textbooks is a form of local, national, regional, and global issues. The environmental textbook in the 7th environmental curriculum is to be composed of contents that could encourage the inquiry of value and change of attitude to take part in environmental preservation on the foundation of the comprehension about ecosystem. Therefore, the present study analyzed the difference of the contents of the environmental issues between the 7th national curriculum and textbooks in the middle school environmental education. The analytical results of this study are as follows: Firstly, there are total 4 sections related to environmental issues in environmental curriculum of middle schools. The content areas that are included ‘Environmental Preservation and Development’, ‘Getting the Hot Earth’, ‘Decreasing Forest and Increasing Desert’, and ‘Pleasant Surrounding and Quality of Life’. Secondly, an environmental textbooks that are used in school education edited for direction that coincide in motive that is ‘real life-centered education’ that is presenting in the 7th environmental curriculum. Specially, introduction to local environmental issues coincides the intent of the curriculum revisions that are ‘environmental education within everyday life’ and ‘contents of local-centered environmental education’. These findings have implications for teaching about environmental issue in school environmental education.

Due to the recent increase in greenhouse gases in atmosphere, world climate is rapidly changing and in turn, the earth ecosystem responds upon the climate changes. Comparing the ecosystem in the past, the present shapes of ecosystem is the result of the serious modification. Fishery resources in marine ecosystem, which usually occupy the upper trophic level, are also inevitable from such changes, because they always react to the natural environmental conditions. The northwestern Pacific is the most productive ocean in the world producing about 30% of world catch. From time to time, however, it has been notified that abundance, distribution and species composition of major fish species were altered by climate events. Furthermore, primary productivity of the ocean is not stable under the changing environments, so that carrying capacity of the ocean varies from one climate regime to another. Major climate events such as global warming, atmospheric circulation pattern, climate regime shift in the North Pacific, and El Nino event in the Pacific tropical waters were introduced in relation to fisheries aspects. The current status and future projection of fishery production was investigated, especially in the North Pacific including Korean waters. This new paradigm, ecosystem response to environmental variability, has become the main theme in marine ecology and fishery science, and the GLOBEC-type researches might provide a solution far cause-effect mechanism as well as prediction capability. Ecosystem management principles for multi-species should be adopted for better understanding and management of ecosystem.

최근의 한 보고서는 2020년대에 지구에게 가장 가능성이 높은 위협으로 기후 변화를 포함한 환경문제를 언급했다. 따라서 오늘날 환경문제는 단순히 어느 특정 지역이나 국가의 문제일 뿐만 아니라 미래의 문제, 그리고 우리가 현재 살고 있는 현재의 문제라는 인식이 필요하다. 기독교 내에서는 창조와 타락, 구속을 기본으로 하는 기독교 세계관을 바탕으로 환경문제에 대한 다양한 관심과 연구가 진행되어 왔다. 이러한 관심은 초기에는 주로 가톨릭 진영에서 시작되었지만, 점차적으로 세계교회협의회(WCC)를 비롯한 복음주의 기독교 진영에서도 지구적 돌봄을 기독교적 책임과 연계시키는 노력이 계속되고 있다. 이처럼 지구 돌봄에 대한 관심이 보다 확대되고 있는 시점에서 이 연구는 기독교 공동체를 향해 다음과 같이 제안했다. 첫째, 환경보호, 생태보존에서 생명신학으로의 전환이 필요하다. 둘째, 자연을 바라보는 생태학에 대한 이해의 전환이 필요하다. 셋째, 기독교적 차원에서는 세속적 환경주의와 차별화된 진정한 회복운동이 있어야 한다. 넷째, 교회는 하나님의 나라를 고대하면서도 이 땅에서 피조세계와 함께 진정한 공동체를 실현할 수 있는 사회를 구현할 수 있어야 한다.

This study was conducted to lay the foundation for considering the qualitative aspects of environmental resources by calculating the weight of each environmental resource to calculate the total amount of environmental resources in Jeju. By comparing and analyzing the results of the expert survey conducted in 2011 and the results of the expert survey conducted in 2011 and 2022, changes in experts' perceptions and implications over time were derived. In addition, based on the results of the recent survey, the weight according to the relative importance was calculated to lay the foundation for calculating the total amount of environmental resources in Jeju. The results of this study are expected to provide basic data necessary for the successful institutionalization of the total environmental resource system by providing a scientific basis for the calculation of the total environmental resource. As a result of comparing the survey conducted in 2011 to the survey conducted in 2022 to establish a total environmental resource management plan in Jeju Special Self-Governing Province, there was a difference in the relative importance of the environmental resource category. Although the ranking between categories did not change, it was confirmed that the relative importance of the natural and local resource environment decreased and the relative importance of the living environment field increased significantly. Over time, the importance of plants and wildlife increased, the importance of landscapes and topographic geology decreased, the importance of wetlands and caves increased, and the importance of Gotjawal, natural monuments, and cultural history decreased. In the living environment category, the importance of water pollution increased significantly, and in the humanities and social environment category, the importance of population increased and the importance of industry decreased. It is judged that most changes in item importance are largely influenced by changes in the background of the times and overall perception. It was confirmed that the importance of plants, wildlife, wetlands, and caves with relatively high awareness and the importance of water pollution, which is emerging as a regional problem, have all increased significantly due to structural problems of population age.

A Gangwon region consisting of over 80% of forest area has industries that have been developed by utilizing its clean region image. However, the recent climate change has increased the forest disease & insect pest as well as the forest fire and the major cause is known to be the increase in the frequency of a drought occurrence. From the aspect of climate change, it can be said that drought and forest are important in every aspect of the adaptation and mitigation of climate change measure as they increase forest disease & insect pest that leads to desolation of usable forest resource. In addition, the increase of forest fire reduces resources that can absorb greenhouse gas, which leads to increase in green house emission. The purpose of this study is to provide a motive for concentrating administrative power for protecting forest in a Gangwon region by selecting a drought management needed local government through a drought forecast according to the climate change scenario of a Gangwon region.

Landscape changes for 20 years between 1981 and 2001 in the Wangsuk stream basin located on the central Korea were investigated on the basis of physiognomic vegetation map made from the aerial photograph interpretation and field check. Changes of landscape structure were noticeable in agricultural field and forest landscape elements. Changes in the agricultural fields due to transformation of agricultural pattern into the institutional agriculture dominated landscape change, although urbanization also contributed to such change. The former change due to change of food production structure originated from socio-economic development during this period and the latter to the overpopulation of Seoul. As energy sources for heating and cooking, fertilizer, and fodder for livestock transform from plant materials to fossil fuel, manufactured one, and grain, succession of forest escaped from direct human disturbance dominated change of landscape structure in forested land. Differently from the positive landscape change in the upper area, change in the lower area deteriorated landscape quality by increasing artificial land. It was estimated that such landscape deterioration in the Wangsuk stream basin would influence water quality of the stream. In order to realize sustainable land-use against such environmental degradation, systematic environmental management based on landscape ecological perspective such as "an eco-plan for creating riparian vegetation belt," which is under preparation by Ministry of Environment, was recommended.
