  • The aim of this study was to examine the current situation of otter inhabitation and conservation and to collect basic information for establishing appropriate policies. We conducted the study around the Bukhan river from April to October 2009, mostly focusing on otter distribution, feeding habits, threats, and conservation measures. We divided the study area into 2 sectors: the dam area and the stream. We found 39 spraint sites in the dam area and 70 in the stream area. A significant difference was observed in the number of spraint sites between the upper stream and the lower stream. To evaluate the feeding habit, we collected and analyzed the frequency and bulk occurrence of the spraints. Among the prey items, fish were the most numerous (36.99%) followed by amphibians (17.22%). Fish showed the highest bulk occurrence in the dam area, and the bulk occurrence of amphibians and insects seemed to increase in the stream area. However, the bulk occurrence in the dam area seemed to be lower than that in the stream area (ANOVA, F = 3.99, p < 0.05). Fyke nets and abandoned fishing nets were found to be the most threatening factors. Further research on the systematic management of otters and the use of stop grids is required for better conservation of otters.

  • The Ministry of Environment of Korea has been releasing Asiatic black bears since 2004 at Jirisan National Park. It exceeded the target number of Asiatic black bears in 2018. As of July 2020, in addition to 67 traceable bears, many Asiatic black bears are dispersed outside Jirisan National Park. Jirisan National Park is a very dense place with more than 3 million visitors every year. In this study, the roads and trails through Jirisan National Park were considered to be the main dispersion factors of Asiatic black bears, and the fragmentation analysis was conducted. As of July 2017, the length of roads and trails in Jirisan National Park was 363.4km. Based on this, Jirisan National Park was fragmented into 163 patches. There is only one place that maintains a single area of more than 50㎢ that is suitable for large mammals to inhabit, and 141 places are less than 5㎢. There are 6 patches of 24 to 200㎢ area suitable for living of large mammals including Asiatic black bears, in Jirisan National Park. Compared to the announcement made by the Korea National Park Service in 2014, activities of Asiatic black bears were rare in areas below 5㎢ area and the frequency of activities was high in more than 20㎢ area. This shows that human activities in protected areas such as national parks can directly affect the activities of wild animals, including Asiatic black bears. Therefore, efforts should be made to improve the habitat of Asiatic black bears by reducing the pressure of visiting for Jirisan National Park. In addition, as a result of analyzing the fragmentation of the park's natural conservation zone 107.7km, 45% of the trail of Jirisan National Park, was opened, which is more fragmentation than other use zones. The park nature conservation zone accounts for about 32% of the total area of Jirisan National Park, but the average patch area is only 2.93㎢ and seven large shelters are located. Therefore the Asiatic black bears are negatively affected. This is the result of inconsistent national park use zone setting and actual park management. In overseas countries, research is active on the negative effects of human activity on ecosystems in protected areas. However, there is a lack of research of that in Korea. Thus, that research is required for protection area management in the future.

  • The purpose of this study is to develop a method to spread out the ecological ponds in urban areas more effectively. It is urgent to supply the ecological ponds in more broad scope to ensure the water space in urban areas which has been dried out. It is necessary to formulate a plan for improving the amenity in the cities through creation a biotop in swampy land by building rainfall ponds. Thus, a model of the ecological pond in this study has been developed by reviewing the related researches which provide the theoretical basis and by considering the characteristics of nature for a naturally approached pond. This study has produced a ecological pond model in order to introduce and spread out damp biotop. Ecological aspects have been mainly considered in designing and building the pond model. This model consists of areas for emerged plants and bog plants and has its advantage in providing animals and insects with habitats and shelters. In addition, the model includes areas for emerged plants, which are very effective in purification of the rainfall from the rooftop. After the construction of the pond, the plants were planted according to the plan, and the infiltration trench was installed beside the pond to drain out the overflow of the pond. The result of this research has shown the possibility of supplying the ecological pond in small parks and in schools of the city in an easy way. Through the application of this pond system, the water cycle and the ecosystem in urban areas will be improved.

  • The increase of wheelchair users due to the rapid growth of elderly population, traffic accidents, and industrial disaster etc. becomes a major issue in our society. Thus, the Convenience Promotion Law was enforced to facilitate the use and installation of convenient facilities for the disabled, the elderly and pregnant women. Currently, not only newly built buildings but also roads and parks are accessed and used by all the people without any hindrance. In contrast to this, so far not many studies on residential space design for wheelchair users have been carried out except for public facilities. So, wheelchair users have to bear the inconvenience in their houses made upon the standards of the general people. Therefore, it is necessary to develop design guideline considering the physical characteristics of wheelchair users and their family members to lead a convenient life. This study was conducted in universal design perspective and intended to establish design guideline of convenient residential space for wheelchair users and general people. To accomplish the objective, surveys for wheelchair users' actual conditions and needs, and video observation were carried out.

  • The research purpose of this study, together with the study of Frank Stella's work and his expansion of the formative arts field, is to rediscover "Amabel" and to present a fresh perspective in evaluating and assessing environmental art objects. The results of this study can be summarized as follows. 1. The study investigated the effect how Frank Stella's work affected American modem art trends. 2. The study helped to re-evaluate Stella's work by examining its expansion into the plastic arts. 3. The study analysed the plastic works of Prank Stella and his effect on plastic arts within the modem art trend of America. In conclusion, Frank Stella played a leading role in today's American art style and had a potent influence on the trends of America's modem U. In recent years, his work has had an impacted on the design of parks and art galleries. America's industrial society is led by the growth of economic power and the development of science and technology. In America's architecture and landscape architecture, such new forms as minimalism functionalism, cubism and abstract expressionism, which have been influenced by art movements, emerged in California and the east coast. Influences of Stella such as these are the remedy for a vested stubborn concept of architecture and landscape architecture by introducing a sense of pictorial space in these fields. In landscape architecture, the introduction of art trends appears in several ways. Mainly the trend of Minimalist Art, influenced by Modernism, can be seen in much Landscape Architecture. Frank Stella contributed to the development of such minimalist art.
