The Office of Korean National Railroads announced a design competition for Kwangyang Station and sought design proposals in October of 2002. The authors collaborated on a landscape design for Kwangyang Station and earned first prize in the competition. The Office decided to construct outdoor public spaces of Kwangyang Station for railroad users, visitors and staff, and local residents. The landscape design covers the following: site inventory and analysis; integration of design program and site analysis; evaluation of design concept; selecting a winning design alternative; schematic design including circulation form and spatial form; and design development including subarea design. In the design process, the authors focused on the integration and interpretation of site conditions as related to the Kwangyang Station building. They also collectively analyzed and considered the physical development of the outdoor spaces of Kwangyang Station. The following are some of the major areas in the design of the outdoor spaces of Kwangyang Station: 1) a plaza for waiting, 2) an entry area for passengers, 3) a train cafeteria, 4) a cultural plaza, 5) an image wall, and 6) a symbolic pond. The plaza for waiting is created as a place for users to wait and rest. The entry area for passengers provides an area for pedestrians approaching, passing and strolling. The train cafeteria features trains, lawns, grasses and trees. The cultural plaza is a main area representing the regional characteristics of Kwangyang. This plaza also provides an area for various public events. The image wall is meant to be an exhibition space for displaying the advancements of Korean National Railroads in sculptural image forms. The symbolic pond consists of an area with symbolic water features and several sculptures with artistic value. In the authors' design, the outdoor spaces of Kwangyang station are created as a new type of public realm with function, regional quality, original identity, cultural context, symbolic meaning and images, and beauty. The designed spaces would be one of the most representative places of interest and attraction in Kwangyang.

The purpose of this study is to have detailed data of the distribution, locations, and the amount of people in the waiting line of the nursing home. Also, we studied the accessibility to the facilities by using Web GIS to analyze the transit time it takes from the nursing home to health center and hospitals. We can provide the basic data that could contribute when future plans for the nursing homes' locations, health and medical policy are made. The results are as follows. 1. The nursing homes are stiffly concentrated in regions of Seoul and Gyeongi-do where large number of the elderly covered by long-term care insurance and the waiting line was very long for the elderlies to enter the nursing homes. In these cities of Ulsan and Jeju where number of the elderly covered by long-term care insurance is relatively small, there were less facilities. 2. The nursing homes located in urban areas had higher occupancy rate and higher number of people in the waiting line. 3. The average time taken by driving from the nursing homes and health center was 10 minutes and there was not a noticeable difference between the cities. Driving from the nursing homes to hospitals in rural areas took 22 minutes which is 2.5 times of the time taken for urban areas. Daegu-si and Incheon-si had relatively short distance from the nursing homes and the hospitals while Jeju-do had the furthest. For rural areas, it is needed for health center to be equipped with a wider medical coverage, have closely connected with hospitals to minimize the differences they have from ones in rural areas. It is also needed to have ambulances equipped for tele-medical examination and treatment system.

In this study, some methods for the organization of space in the welfare center for the disabled are suggested corresponding to the change of welfare paradigm for the disabled, by means of investigating and analyzing the existing organization of space, division of the areas and relevant programs. The results of the study are as follows. 1) The method of the spatial organization in the welfare center for the disabled is divided largely into an area of the welfare complex center used as a facility of uses and an area of the controlling center that manages and makes use of domiciliary welfare. 2) The division of counselling and management is the center for the aforementioned two areas. This division occupying the minimum space in the welfare center has to be expanded. Besides, the space for the volunteers for 'domiciliary welfare' is necessary. This can be administered synthetically along with the room for volunteers in the division of social rehabilitation. 3) It is necessary for the division of medical rehabilitation to have a common waiting area due to its close connection with other treatment rooms. It should be recommended to have it in the water treatment room. It is required to have a parents' waiting area in the treatment room for child rehabilitation. 4) In case of the division of educational rehabilitation, the daytime care center should be closely related to the division of medical rehabilitation. Meanwhile, the classrooms after school have a limited use so that they can be shared with the room for female rehabilitation in the division of social rehabilitation. 5) It is in reality for the division of social rehabilitation to have an expanded area of domiciliary welfare. The room for volunteers for domiciliary welfare should be arranged, too.
