  • From the lessons after the Nakhodka oil-spill in Jan. 1997, oil slick detection by using remote sensing data and assimilating the data to the simulation program is important for monitoring the oil-drift pattern. For this object, we are going to construct the oil-spill warning system for estimating the oil-drift pattern using remotesensing/numerical simulation Model. Additionally we plan to use this system for restorating oil-spill damage domestically, such as estimating the ecological damage and making the priority fur restorating the oil-spilled shoreline. This report is intended to summarize the role of geo-informatics in the oil spill accident by not only paying attention to the effect of information provision/information management via the map, but also reporting the interim result in part based on the details discussed in the processes of recovery support and environmental impact assessment during the Nakhodka's accident.

  • The central theme of Habital heterogeneity is to provide animals with habital complexity or structural diversity and to allow resource partitioning among individuals. In turn, the leads to population stability because prey can escape more easily with more hiding places causing less population fluctuation. Species diversity is characterized due to more potential niches both horizontally and verticall. Empirically, in homogeneous habitats population was less abundant, reproduction and survival were lower, spacing behavior, competition and dispersal were higher than in heterogeneous habitats. The results imply that diversity and conservation of species can be maintained through providing heterogeneous habitats.

  • The purpose of this study is to develop the assessment categories, items and detailed criteria for environmental friendly evaluation on the School. The results of this study brings on promoted environmental friendly appreciation, energy and resource conservation, reduction of contaminant, improvement of environment quality in and around buildings. For this purpose, analysis of domestic and foreign environmental friendly architectural citation screening system-BREEAM(1991), LEED 2.0(2001), GBTool(2002), KICTEAC (2000), KOEAM(2000), etc.-was preceded, and through interview, survey and forum with professional group, the developed evaluation items were verified and reappraised. The developed evaluation items were composed of thirty four essential evaluation items and nine bonus items.

  • The purpose of this study was to investigate adolescents' individual and microsystem variables including relationships with parents and friends affecting adolescents' experiences of mobile social networking site (SNS) cyberbullying based on the human ecological perspective. Data came from 344 middle school students who lived with both their parents in the Seoul and Gyunggi areas. A multiple regression analysis showed that adolescents' characteristics, relationships with parents, and friends were associated with their experiences of mobile SNS cyberbullying. These findings suggest that good relationships with parents could be protective factors for adolescents to reduce mobile SNS cyberbullying. However, adolescents' characteristics including aggression, depression, and delinquent peers were positively associated with adolescents' experiences of mobile SNS cyberbullying. This study highlights that various environments are closely related to adolescent development.

  • The purpose of this study is the comparative analysis of Susan citizens' images of Eulsook-do as a coastal tourism destination before and after the construction of a road bridge across the Nakdong estuary in order to analyze local people's changes in leisure patterns. Analysis of the images of a pre-construction Eulsook-do that people aged both 40 and less and 50 and more had on five dimensions showed values higher than zero(0) that suggests neutral image, while their images of a post-construction Eulsook-do showed the shrinking size of pentagon on all five dimensions: ET(Entertainment), CA(Culture & Art), EE(Environment & Ecology), RC(Recreation) and LP(Leports) dimensions. Its pre- and post- construction image analysis conducted 20 years after it came to be built finds that the road bridge construction has led to the ecological, environmental disruption of the coast and the lower Nakdong river, having negative influence on the images of Eulsook-so.

  • Linzhi Native Pig is a unique local breed recently discovered in the hinterland of Tibet. Its geological distribution, natural environment and ecological conditions have been explored. Using random sampling in typical colony of classification and standard animal-scientific and biogenetic techniques, we examined its contour features, size and weight, reproductive performances, carcass characters, meat quality, fresh-keeping features and the frequency distribution in the 19 structural gene loci encoding enzymes and proteins; according to folklores and Tibetan, Chinese and English history books, the materials and literature of Tibetan Studies, we have analyzed its origin and affirmed the fact that its products have been consumed as Tibetan medicine resources. Our findings make certain that Linzhi Native Pig holds great potential value in economy and culture.

  • The biodegradability test of bulking agents in feces composting process is conducted to increase the management efficiency for environment-friendly rural toilet developed by National Rural Resource Institute in 2001. In the case study through references and field study, ash, fallen leaves, and wood chips are commonly used in the ecological toilet. Extension officers and farmers prefer rice straw, fallen leaves, and chaff among the rural resources as a bulking agents in the aspect of getting and storage as the result of questionnaire survey. As the result of biodegradability test including the temperature change, $CO_2$ gas production, and C/N ratio change of composting pile under the condition of aerobic composting apparatus, rice straw and chaff are good bulking agents for environment-friendly rural toilet. It is recommended that easy getting materials among the above mentioned materials are used for bulking agents as the region and season in environment-friendly rural toilet.

  • There is a controversy on developing or preserving Kwangduksan(Mt.) located in Cheonan and Asan. Kwangduksan has a grand scenery, many of cultural properties, and rare animals and plants like fireflies. So the citizens of Cheonan and Asan have recognized its cultural and ecological value as yet. In this study, an economic basis for preserving it was presented to prevent developing thoughtless for the environment. Preservation value of it was estimated about 44 billions by CVM. This result shows the environmental value of Kwangduksan is very great. If people feel importance of environmental resources more and more, this value of Kwangduksan will be greater and greater.

  • This study is performed to establish the basis of the development of unique tropical botanical garden that will be connected with the identity of the local inheritance resources, 'Silla'. The glasshouse is the traditional 'Silla; housing and the landscape facilities are tried to imagine 'Silla' kingdom. Combination of the plant exhibition and the cultural inheritance resources can create their own unique theme. The garden divided into five spaces by life cycles of plants and the purpose of appreciation, the palm garden, ornamental foliage garden, flower garden, water lily garden, and tropical fruits garden. The appropriate flowers and trees are selected by their flowering time and the purpose of enjoyment. Especially, Ficus religiosa is the symbol plant of buddhism which is the state religion of 'Silla'.
