본 연구는 생태계보전지역인 둔촌동습지의 모니터링을 통한 생태적 복원 및 보전계획을 수립하기 위해 실시되었다. 모니터링 기준으로는 항목, 방법, 시기, 횟수 등을 설정하였다. 모니터링 기준에 따라 조사한 결과 식물생태분야에서 대상지내 식물종은 총 39과 116종 19변종 1품종으로 총 132종류가 출현하였고 이중 자생종은 85종, 외래종은 47종이었다. 월별(4∼9월) 현존식생 모니터링 결과 습지성 초본식물군락 세력이 증가추세이었고 특히 고마리군락의 세력이 왕성해졌다. 아울러 기존 경작지를 중심으로 천이초기식물과 귀화식물의 출현빈도가 높았다. 동물생태분야에서 야생조류는 34종 378개체, 양서류는 4종 5개체, 곤충류는 11목 52과 153종이 조사되었다. 무기환경분야에서는 지하수위. 수질. 토양특성을 분석하였는데 이중 지하수위는 0.0∼89.0cm이었고 토양에서는 Ca++의 함량이 2.18∼13.73cmol/kg로 나타났다. 모니터링 결과를 바탕으로 한 연구대상지 생태적 복원구상을 습지생태계 복원구상. 용출지 복원구상. 산림생태계 복원구상으로 구분하여 기본방향과 각 공간별 세부계획을 제시하였다. 습지생태계 복원구상에서는 기존 습지지역의 보전과 경작지로 활용되던 습지지역의 복원구상을 수립하였으며, 용출지복원구상에서는 용출지 및 진입부의 복원을 수립하였고 산림생태계 복원구상에서는 건조성 산림 생태계와 습지성산림생태계의 복원 및 주연부지역의 야생조류 서식처 계획을 수립하였다.

Present work aims to establish an integrated management system of environmental data base for nine typical wind holes or air holes in Korea. It basically deals with definition, geographical distribution, morphological pattern, physical characteristics and anthropogenic environments of wind hole to propose systematic preservation strategy of their periglacial landscape and flora, which are known to be sensitive to global warming. Wind hole, in which cool air blows out during the summer, but mild air comes out during the winter from a cave or hole, is frequently found on northwest- and north-facing slopes on the terminal point of steep talus, block field, and block stream, and can be categorized into three types, i.e., talus, cave and sink types. Environmental characteristics of nine wind holes are analyzed on the basis of their geology, landform, climate, soil, hydrology, vegetation, road, footpath, land-use, and management system, and relevant DB are prepared. Wind hole areas with unique landscape and ecological values need to be designated as a nature reserve, and zoning of core, buffer, and transitional zones are required for the multi-dimensional preservation of periglacial landscape and ecosystem. Phytogeographical values of glacial relict plants, including mountain cranberry(Vaccinium vitis-idaea) at its global southernmost limit at Bangnaeri wind hole, Hongchon County, Gangwon Province of Korea are discussed in detail as a floristic refugia in connection with climate change during the Pleistocene Epoch and potential in-situ and ex-situ preservation sites in the future.

본 연구에서는 합리적인 개발과 생태계의 보전을 위한 산지구분 조정을 위해 운영되고 있는 산지특성평가제도를 위한 평가 지표의 개선방안을 제시하였다. 현행 산지특성평가에서는 지표간의 중복성이 검토되지 않아 자료수집에 대한 효율성이 떨어지고, 지자체의 산림유형 및 개발여건을 고려하지 않고 산지의 등급을 산정하기 위한 각 지표의 중요도를 동등하게 적용함으로써 보전산지의 지정 해제에 대한 지역간의 편차를 유발하고 있다. 따라서 본 연구에서는 39개 시군을 대상으로 지표간 상관분석을 통해 영급과 상관성이 높은 경급을 제거하여 지표의 통계적 중복성을 제거하였고, 지역별 산림환경특성을 반영할 수 있도록 산지의 등급은 표준정규분포를 이용하여 산지유역유형별 특성에 따라 보전성향 및 해제성향의 비율이 할당될 수 있도록 하였다. 경급을 제외하고 9개의 지표를 이용하여 산지특성평가를 실시한 결과를 경급을 포함한 10개의 지표를 이용하여 산지특성평가를 실시한 결과와 비교했을 때, 전체적으로 등급별 필지수의 변화는 A등급을 제외하고 다른 등급에서 발생하였으나 변화 필지수 및 면적은 크지 않은 것으로 분석되었다. 또한 산지유역 유형별 산지특성평가 점수를 분석한 결과 도시형 및 도시주변형은 산야형, 주요산줄기인접형 및 해안도서형보다 점수가 낮게 평가되어 상대적으로 해제성향이 높게 나타났다. 이를 바탕으로 표준정규분포 방법을 적용함으로써 A, B 등급으로 판정되는 경향이 증가하고 C, E 등급이 감소함으로써 보전성향으로 평가될 수 있는 잠재력이 증가하는 것으로 분석되었다. 따라서 본 연구에서는 각 산지유역유형별 평균값과 표준편차를 이용하여 표준정규화를 수행함으로써 지역간 보전 해제성향 필지수의 불균형을 해소할 수 있는 방안을 제시하였다.

10kW wind turbine has been successfully commissioned at the King Sejong station in April, 2006. The wind turbine installed is a part of the R&D program for developing a solid wind/diesel hybrid power control system for a remote area such as Antarctica. At the same time, the current research aims to develop an anti-icing and de-icing technologies for a small wind turbine rated under 50kW. Since its commissioning, the turbine has generated about 500kWh for 47days without any system faults. Although sufficient data have not been obtained yet, any trouble has not occurred in the wind/diesel hybrid system based on the current analysis. Concerning on the environmental impact by the wind turbine operation, the turbine is installed within the station boundary in order to meet the Madrid protocol. Therefore, wind turbine operation meets the international requirements for preservation of antarctic ecosystem.

This study examines the development and management of the Herb Island in Japan, and explores influences of the herb garden on a rural community. The result suggested that the development of a herb garden can make a major impact on a rural community's econmoic stability and growth, and low-input cultivation of herbs serves to the ecosystem and soil conservation. In order to foster the herb industry in Korea, three aspcets should be considered. These are as follows. 1. Selection of suitable kinds of herbs and sites for Korean natural environment,and planning for proper landuse should be carried out first. 2. Proper policies for a herb garden to help local economy should be established. 3. Development of programs and experts on environmental education should be included in planning herb gardens in order to contribute to natural environment preservation.

We are, now in the 21st century, that environmental preservation and the campaign for bio-diversity protection are very important issues the government must deal with as nation's main policy. To make road and building construction, housing land service, construction of golf fields, and various development works, we have made artificial topographical alterations and as a result, the cut-slop has been increased. However, without the proper study and clear planning, revegetation for the stability of the cut-slop has worked out. These efforts now are causing derangement of an ecosystem and spoiling the nature without considering for ecological adaptation. Therefore, we are going to find out the Revegetation Method to Cut-Slopes considering both the ecological adaptation and harmony with the nature.

The purpose of this study is to suggest an environment-friendly design method of ecological architecture complex, with the reference to foreign cases. The ecological architecture is very similar to the natural ecosystem, but there is increasing international scientific consensus that human activities are having a discernable effect on the global climate. The most important thing is keep going harmoniously between preservation and development relevant with nature. In the process of ecological approaching concept, we need a method that from "architecture in a nature" to "architecture as one section of the nature" would be extended further, also the purpose of this study aims to achieve these kinds of ecological architecture. As a result of, in this Age of industrial science, we are proposing useful materials and suggestion regarding the ecological architecture planning of Korean cities, by preestimating the characteristics of a city heading toward the Age of the new ecological environment.

We investigated the education process of an environmental experiment in middle and high school. The major objective was that students understand about biological toxicity of endocrine disruptor. We used bisphenol A in environmental experiment to educate them about the effects of endocrine disruptor. The test animal was zebrafish (Danio rerio, wild type) which is very easy to use in the school experiment class. We educated the high school students (n=25) in Suwon through this teaching program. Finally we analyzed the effect of research education between two groups, education students (test) and non-education students (control). This experiment showed there were some positive effects on environmental reorganization of students. They understood the affect of endocrine disruptors in fish and man. Specifically, understanding the importance of preservation of ecosystem increased in the test-education group.

Although a dry-system tunnel is not good for reasons fo economy and construction, it has been applied to some tunnels under construction owing to the advantages of good long-term maintenance of tunnel, prevention of consolidation settlement due to the drawdown of groundwater, preservation of the ecosystem, cutailment of operation cost, and so on. The stability of groundwater and the change of the applied water pressure after water proofing were analysed by the finite element method. Using this result, an example of designing the secondary lining for the dry-system tunnel which is to be constructed in low-permeability hard rock was presented.
