For a few people's leisure, the natural environment have being deteriorated ceaseless. The plan of the Chungchongpuk Province and the Yungdong District in Chungchongpuk-do which drive foreword the sport and leasure complex designed to construct ski slopes, golf course, and resort hotel in 6,000,000 $m^2$ of natural ecosystem around the Mulhan Valley at Mulhan-ri Sangchon-myon Yungdong-kun Chung-chcngbuk-do by Dongsin Leisure have concerned decrease on biological diversity serious. This study carried out by census Amphibia and Reptilia fauna in the Mulhan Valley to expect the impact of animal diversity by construction of leasure complex and to call attention to understand that impact. 8 species in 5 Families of 2 Orders in Amphibia and 5 species in 2 Families of 1 Order in Reptilia were observed in the Mulhan Valley during June 24, 1994 to June 25, 1994 which showed to be similar to the Natural Park in Korea. 4 of 8 species in Amphibia(Hynobius leechii, Onychodactylus fischeri, Bufo bufo gargarizans, and Rana dybowskii) and 3 of 5 species in Reptilia(Eluphe rufodorsata, Dinodon rufodonatum rufodonatum, and Agkistrodon saxatilus) were revealed the Special Wild Animal recorded by the Ministry of Environment in 1993. Therefore, the Minjujisan seems to have highly reason to conservation by these animal diversity. Around the Minjujisan province was significant connecting the Taebaek Mountains and the Sobaek Mountains on biogeographically with Dokyusan National Park. The plan of Leasure complex in the Mulhan Valley should be cancel in consideration of destruction around the Dokyusan National Park severely by the Muju Resort, Ski slopes, etc. The Minjujisan must be conserve to the Zone of Natural Environment on Amphibia and Reptilia diversity and animal migration route.

해수관상용으로 그 인기도가 높은 상어류는 모두가 자연에서 채집된 후 관람용 대형수조 또는 개인용 소형수조 내에서 순치 후 관상용으로 사육되고 있다. 그러나, 자연에서 채집된 대부분의 개체는 인위적인 수조 시설 내에서의 생활에 적응하는데 실패하여 결국 거의 대부분의 개체가 짧은 기간 내에 사망하게 된다. 따라서 이 연구는 인공 종묘 생산 시설에서 해수 관상용 상어류의 종묘 확보를 목적으로 실시하였다. 우리나라 제주 연안에서 채집이 비교적 용이한 까치상어 Triakis scyllium와 별상어 Cynias manazo 2종의 상어 친어를 확보하여 인공 사육 시설에서 사육하면서 수조 내에서의 자연 교미와 자연 산란에 성공하였다. 친어와 치상어의 사육관리는 자연해수를 사용하여 15~40ton 크기의 콘크리트 수조에서 사육하면서 전갱이와 같은 생사료 또는 전갱이와 어분을 주성분으로 하는 습사료를 만들어 1일 1회 급이하였다. 까치상어의 인공 종묘는 수 차례의 사산을 거듭한 끝에 2003년 5월 18일과 6월 8일 두 차례에 걸쳐서 매우 활력이 좋은 상태의 치어가 출산하였다. 별상어도 수 차례의 사산을 거듭한 끝에 2003년 5월 25일 건강한 상태의 치어를 출산시키는데 성공하였다. 지금까지 산출된 까치상어의 출산시 평균 전장은 25.70$\pm$0.88cm 평균 체중은 58.32$\pm$4.86g이었으며, 별상어의 출산시 치어의 평균 전장은 27.26$\pm$0.57cm였고 평균 체중은 55.32$\pm$1.69g로 두 종 상어의 평균 전장과 평균 체중은 유사한 경향을 보였다. 그러나, 산출 후 사육 관리 과정에서 관찰된 까치상어와 별상어의 월간 성장 중 전장을 비교한 결과, 까치상어는 1개월 전 대비 15.06%의 성장을 보였으나, 별상어는 3.15%의 성장을 보여 까치상어 보다는 별상어의 길이 성장이 느린 것을 알 수 있었다. 까치상어와 별상어의 월간 성장 중 체중을 비교한 결과에서도 까치상어는 1개월 전 대비 34.11%의 성장을 보였으나, 별상어는 2.25%의 성장을 보여 까치상어 보다는 별상어의 체중 성장이 매우 느린 것을 알 수 있었다. 출산 관리중인 까치상어와 별상어 치어의 성비를 조사한 결과, 까치상어는 ♀:♂=1:1.28, 별상어는 ♀:♂=1:2.50으로 별상어의 암 수 성비가 매우 불균형한 것을 알 수 있었다. 그리고 까치상어와 별상어의 암ㆍ수간 성장 차이를 조사한 결과, 까치상어와 별상어의 암ㆍ수간 성장 (전장, 체장 및 체중)에는 큰 차이가 없었다. 현재, 인공 사육 시설에서 관리중인 까치상어는 64마리이며 별상어는 7마리이다. 결국 소형의 수족관내에서 해수 관상어로서 사육하기 위한 조건으로서 너무 급격한 성장을 하는 어종인 경우에는 관상 기간이 짧아져 조기 폐기하여야 하는 단점을 감안하면 까치상어 보다는 별상어의 관상가치가 높을 것으로 판단되며, 반대로 대형 관람용 수족관의 경우에서는 별상어 보다 성장이 빠르고 운동력이 활발한 까치상어를 전시관람용으로 이용할 경우 전시효과가 높을 것으로 판단된다.

Solar power facilities to reduce carbon emissions are continuously being installed in forests, farmland, city, and on water. However, research on visual preferences and the psychological impact on observers after installing solar power facilities is insufficient. Therefore, in this study, shooting was conducted according to the viewing distance of the near, middle, and distant views of Hapcheon Dam, Korea's largest floating photovoltaic power plant. The acquired images were edited using Photoshop to compare the presence or absence of floating photovoltaic power generation facilities. In addition, psychological changes and visual preferences were analyzed through an EEG test and questionnaire among 50 participants. The results are summarized, as follows. First, the installation of water photovoltaic power generation facilities has a passive impact on the subjects' psychological changes and visual preference. Second, the psychological changes due to the installation of water photovoltaic power generation facilities were judged to affect almost all research subjects, regardless of nationality, gender, or universisty major. Third, the visual preference for installing the water photovoltaic power generation facility is low, which can be interpreted as the water photovoltaic power generation facility negatively affecting the "friendliness" and "naturalness" of the landscape. In addition, this change in visual preference was found to differ depending on the gender and universiity major of the subjects. Fourth, the psychological change and visual preference of the floating photovoltaic power generation facility according to the viewing distance, found that the close range had a higher effect than the middle and distant ranges.

The coastal area is the place where two conflicting values provide opportunities for recreation, tourism and conservation of the natural environment. Most of these coastal areas have been disregarded in terms of tourism because of the high value placed on natural resources. Management strategy has usually been first on the priority list of natural. resources. However, due to the significant number of visitors, the Important-Satisfaction Analysis(ISA) was applied as a mean of complement since the 1970s. This study analyzed the difference between visitor satisfaction and the importance of the main management strategy targeting visitors to Sun-cheon Bay Ecological Park on weekdays and weekends. Results show that Sun-cheon Bay Ecological Park and the city government have paid a lot of attention and invested a lot of money, but efficiency of publicity didn't come up to their afford. Therefore, we should prepare information facilities, public education facilities and human power. Also needed are visitors' temporal-spacial control to set specific programs and a guide for information education control. It means visitors' company forms change depends on weekday and weekend. In addition, a breeding space for birds should be built for observation, education and exhibition to help meet visitor expectations. Visitors' positive satisfaction might be provided in establishing strategy as a very important measure in limited area. In conclusion, this study might be provided as preliminary data when the management strategy and related guidelines are established through the management priority of coastal regions where importance and satisfaction conflict.

We have carried out integrated research including field survey and numerical modeling to appraise the applicability of SP method to the leakage problems of irrigation facilities. The leakage pattern of the dike studied here can be classified into the three categories: leakage through the abutment, leakage by piping through dike, and leakage due to the composite effects of landslide and distortion of the dike structure. for the numerical modeling to interpret quantitatively SP survey results acquired at dike, we have modified the computer code proposed by Sill (1983) to apply to the leakage problems. The numerical studies match the characteristic patterns of SP anomalies according to the leakage types and appear to be very useful to interpret the leakage zone and path. The SP monitoring results were also well coincided with tidal variations observed at every embankment so we found the SP method is quite effective not only to detect the leakage zone but also to determine the leakage trend. The numerical modeling results also reproduced the SP anomalies due to seawater leakage in the embankment.

This study aims to assess the current understanding of the landscape of wind power facilities as renewable energy sources that supply sightseeing, tourism, and other opportunities. Therefore, social media data related to the landscape of wind power facilities experienced by visitors from different regions was analyzed. The analysis results showed that the common characteristics of the landscape of wind power facilities are based on the scale of wind power facilities, the distance between overlook points of wind power facilities, the visual openness of the wind power facilities from the overlook points, and the terrain where the wind power facilities are located. In addition, the preference for wind power facilities is higher in places where the shape of wind power facilities and the surrounding landscape can be clearly seen- flat ground or the sea are considered better landscapes. Negative keywords about the landscape appear on Gade Mountain in Taibai, Meifeng Mountain in Taibai, Taiqi Mountain, and Gyeongju Wind Power Generation Facilities on Gyeongshang Road in Gangwon. The keyword 'negation' occurs when looking at wind power facilities at close range. Because of the high angle of the view, viewers can feel overwhelmed seeing the size of the facility and the ridge simultaneously, feeling psychological pressure. On the contrary, positive landscape adjectives are obtained from wind power facilities on flat ground or the sea. Visitors think that the visual volume of the landscape is fully ensured on flat ground or the sea, and it is a symbolic element that can represent the site. This study analyzes landscape awareness based on the opinions of visitors who have experienced wind power facilities. However, wind power facilities are built in different areas. Therefore, landscape characteristics are different, and there are many variables, such as viewpoints and observers, so the research results are difficult to popularize and have limitations. In recent years, landscape damage due to the construction of wind power facilities has become a hot issue, and the domestic methods of landscape evaluation of wind power facilities are unsatisfactory. Therefore, when evaluating the landscape of wind power facilities, the scale of wind power facilities, the inherent natural characteristics of the area where wind power facilities are set up, and the distance between wind power facilities and overlook points are important elements to consider. In addition, wind power facilities are set in the natural environment, which needs to be protected. Therefore, from the landscape perspective, it is necessary to study the landscape of wind power facilities and the surrounding environment.

This study aims to find out the construction process and planning characteristics of Suwon and Hwa-sung in 18th century from the point of water system. This study has an explanatory approach. The planning intents in the water system was driven out by analyzing various planning elements in relation to water system in the process of constructing Hwa-sung in 18th century. Using Entire Map of Hwa-sung, land registration map made in 1911 and topographic map of 1/10,000 scale made in 1917, water system and interpretation of spatial structure in Hwa-sung were analyzed. The results are as follows(Planning characteristics of the water system in Haw-sung in 18th century are as follows). Firstly, in determining the spatial structure and location of Hwa-sung, water system had an important role. Secondly, integrated drainage system was planned by the organization of natural and artificial water stream. Thirdly, the main street system and land use structure were planned in relation with water system. Fourthly, territoriality of main area was planned with water stream. Fifthly, ponds were constructed for flood control and they had important role as landscape elements. Sixthly, water stream was used as intentional BiBo element. As a result of the study, the weater system of Hwa-sung in 18th century was planned by the organization of natural and artificial water stream in relation with the location of new town and wide area's spatial structure, street system, land use structure, territoriality of main area, terriflood control, water quality protection, landscape, 비보 and urban daily life.
