When Web-based special retrieval systems for scientific field extremely restrict the expression of user's information request, the process of the information content analysis and that of the information acquisition become inconsistent. Accordingly, this study suggests the re-ranking retrieval model which reflects the content based similarity between user's inquiry terms and index words by grasping the document knowledge structure. In order to accomplish this, the former constructs a thesaurus and similarity relation matrix to provide the subject analysis mechanism and the latter propose the algorithm which establishes a search model such as query expansion in order to analyze the user's demands. Therefore, the algorithm that this study suggests as retrieval utilizing the information structure of a retrieval system can be content-based retrieval mechanism to establish a 2-step search model for the preservation of recall and improvement of accuracy which was a weak point of the previous fuzzy retrieval model.

In recent years, the relationships and inter-dependencies between the countries in East Asia have deepened, and the vision for regional cohesion such as the East Asian Community have been gradually elaborated. A Grand Design for Northeast Asia is one of these comprehensive visions that aim to improve and develop international infrastructure through cooperation in the field of transportation, energy, environment, and information technology. This study paid attention to the possibility for a system for regional cohesion and cooperation in spatial development in East Asia, and analyzed the roles of the ESDP according to the requirements of the East Asian situation. As a result, it was understood that while the development of infrastructure is a main stream in the case of the regional cohesion in East Asia, the cooperative visions for the conservation of natural and cultural heritage, which are being positioned as an important policy in the EU, have not been seen. It is a very important subject to promote the policy cohesion/cooperation on the conservation and management of natural/cultural heritage and the development of tourism infrastructure for the sustainable development of East Asia, considering the trends in the growth of the interchange population and tourism market in East Asia. It was discussed that the role of research networks like the International Landscape Architectural Symposium of Korea, China and Japan is becoming important in supporting this policy cohesion and in grasping the present conditions and trends of the spatial development of these counties.

The purpose of this study is to prepare a plan for improving the bird habitat environment of Linear Park. To this end, after grasping the status of bird habitats on the Gyeongchun Line Forest Road, a representative linear park in Seoul, the habitat environment was evaluated and the correlation with the bird habitat was analyzed to derive a plan to improve the habitat environment. The results for correlation between diversity of birds and habitat environment were as follows. For the habitat environment inside the park, the order of positive correlation was in the order of park area (0.92), number of insect species (0.87), green area ratio (0.77), average width of linear park (0.74), Biotope area ratio (0.73), Immigration planted species (0.57). Also, for habitat environment outside the park, the bird diversity was influenced in the order of area outside the park (0.88), green area ratio of the park (0.76). Thus, in order to enhance the diversity of birds found in the park, the bird habitat environment inside the park needs to expand the park area, secure insect diversity, enhance green area ratio and ecological area ratio, expand the width of linear park, and lower the impermeable layer. For the bird habitat environment outside the park, wider area, green area ratio, and forest area of the park influenced on better bird habitation while lower ratio of road space and building-to-land ratio influenced on higher bird diversity. It is necessary to create an environment inhabitable for various species of birds and to make a healthy and pleasant city urban system for co-existence of human and living creatures.
