In this study, the landscape of Insa-dong was interpreted from the viewpoint of a social construction of landscape, which regards the dynamic process of landscape change as more important than landscape visibility. This viewpoint also regards landscape as the result of its interaction with certain actors. From a review of previous studies on the same subject, it was found that the physical environment, institutions, and images are essential factors influencing landscape change. Insa-dong, which was Kwanindaing and Daesadong during the Joseon Dynasty, acquired symbolic meaning as a traditional area during the Japanese colonial period because of its many antique shops and Korean-style buildings. In 1970, the establishment of modern galleries in the district added to its image as a haven of the traditional Korean culture. Insa-dong thus eventually came to be referred to as "the street of traditional culture" by the people of Korea. Thanks to global festivals like the Asian Games, the Olympics, and the World Cup, Insa-dong's reputation as a cultural tourist destination has become stronger as these festivals created a need for a place in Korea where the country's traditional culture can be showcased to foreign tourists. After the mid-1990s, the merchants of Insa-dong began to cash in on the district's image as a showcase of traditional Korean culture due to the economic depression that emerged then. The people of Insa-dong and those outside it, however, came to feel that this trend damaged the district's image. Therefore, the people of Insa-dong and the district's local government started a movement to restore the aesthetic value and symbolic meaning of the district's landscape. This effort induced institutional change. Insa-dong used to be a natural haven of traditional Korean culture. Its landscape has recently been reconstructed so that this image could be restored. This process was made possible by the active interaction of diverse people: merchants, users, administrators, and NGOs.

The Seoul Housing Corporation pronounced a design competition for Eunpyeng New Town District 2 in March of 2005. The authors collaborated on this design and won rot prize. Design guidelines of this competition were to make environmentally sustainable design, to develop as a resort site and cultural place for everyday life of residents, to link with green fabric of the district, and to elevate positive image and identity of Eunpyeng New Town district by creating a attractive landscape. The authors developed design concept and strategy within the guidelines and site conditions. The environmental setting of this site was characterized by mountain to the rear of the site with a stream passing through the district and the front of the site. This is the most important condition for the location principle of residence in Fung Shui theory. Therefore, the schema of the design was introduced by Fung Shui and Chi of place. To evolve design concept, we reinterpret the Fung Shui and Chi in the site combining with modem landscape design strategy, so that good place making could bring about well-being life of residents. By doing that, design concept of the proposal evolved as follows: 'fullness of comfortable life', 'adaptation of nature', 'inspiration of natural force'. This design approach is critical reevaluation of regional characters employing modem strategy. It is a conscious strategy of critical regionalism as distinguished from the traditional site oriented approach. The following are some of the major features in the design: green network and water recycle system in the site, promenade of forest with the experience nature, link to community core, theme gardens with plants having strong fragrances, terrace gardens with different level of housing type, playgrounds and resting places with many types, human scale facilities for residents.

In order to achieve an efficient urban regeneration of the nation, it is required to determine the extent of decline nation-wide and the declined areas for each district and also to evaluate the potentials of the concerned areas. For this task to be accomplished, a construction of a comprehensive diagnostic system based on spatial information considering diversity and complexity is required. In this study, a total information system architecture for urban regeneration is designed as part of the construction of such a diagnostic system. In order to develop the system, a city and district level unit decline diagnostic indicators has been constructed and a decline diagnostic system has been developed. Also, a scheme to promote the advancement of the system is proposed. The DB construction is based on the city and district level nation-wide and metadata for the concerned level is constructed as well. The system is based on the Open API and designed to be flexible for extension. Also, an RIA-based intuitive UI has been implemented. Main features of the system consist of the management of the indicators, diagnostic analysis (city and district level decline diagnosis), related information, etc. As for methods for the advancement, an information model in consideration of the spation relations of the urban regeneration DB has been designed and application methods of semantic webs. Also, for improvement methods for district unit analytical model, district level analysis models, GIS based spatial analysis platforms and linked utiliation of KOPSS analysis modules are suggested. A use of a total information system for urban regeneration is anticipated to facilitate concerned policy making through the identification of the status of city declines to identify and the understanding of the demands for regeneration.

Necessity of paradigm change has been awared in urban redevelopment especially, in housing regeneration from uniform scratch without serious consideration about resident's lives to holistic approach based on local culture and residents' participation. The purpose of this research was to identify community places recognized and attached by residents of a housing improvement district which was scheduled to be changed for improvement of the area, in near future. This research itself was considered as an resident participation technique. Group interview at a field site was carried as the main research methodology. As results, valuable places cherished by residents were identified. Most of them could be explained in relation to religious leadership, traditional cultural heritage and democratic movement. In regeneration process those places which have a strong tie with residents needs to be deliberately considered as a target to be preserved rather than demolished. The places also play a role in diffusing a livable village making movement. The result is expected to be used to make a cognitive and emotional community map of residents which is meaningfully differentiated from just a physical and geographical map. The places, place recognition activities and diffusion movement for common appreciation can be a basic foundation for residents participation in improving their housing neighborhood environment, and in creating value added strategies for the area.

In order to save the energy in apartment houses, it is essential that the energy amount consumed in heating per household should be surveyed and analyzed according to heating method, which can be classified into unit, central and district methods. As a basis, we selected the household with nominal area of 32 py. because it accounts for the most percentage in Korea. It is estimated that the gas amount for cooking is 90 ㎥ and the energy amount for hot water supply is 11.41 GJ for a year, which is necessary to calculate the heating energy. Through the survey of actual energy consumption in Seoul and Gyeonggi, the energy amount used in heating can be obtained according to the heating type: 26.02 GJ/year for the unit heating, 28.09 GJ/year for the central heating and 40.61 GJ/year for the district heating.

Many reclaimed tideland projects in Korea have been conducted to secure the food self-sufficiency. In fact, the domestic food self-sufficiency has been greatly improved and reclaimed tideland projects contribute to Korea's economic and social development directly or indirectly replacing agricultural lands from urbanization, industrialization. As result, current self-sufficiency of rice reach the demand(104.6%) while rate of upland crops has less than 30% of self-sufficiency rate and corn, wheat, soybeans, etc. are virtually dependent on imports. Domestic price of crop is expected to be unstable by trend of international grain prices. Therefore, developing reclaimed tidelands as upland which is originally constructed for paddy fields could be a good option to become steady in domestic crop market and dedicate to ensure a stable food security. The study to prepare measures for dealing with disasters in reclaimed tidelands of west coast district is required in order to utilize those sites for infra construction of multi-utilization in those sites and The result of flooding analysis in this study can suggest policy direction for practical utilization of reclaimed tidelands in yellow sea area.
