It is not so long that the cultural industrial sector has been noted as one of the major engines of regional economy in Korea. In parallel with balanced development strategies recently emphasized in the Korean regional policy, there has been a wide range of investment to formulate cultural industrial districts in major cities. This trend of investment focus has changed the development strategies of each city. There are criticisms, however, to this public sector-dominated nurturing of cultural economy. This paper overviews the recent policy of cultural industrial districts in Korea, in terms of its background, institutional basis, performances, and some evaluations. Some suggestions are provided in order to make the policy successful; emphasize developing the culture industry itself, develop clusters specifically focused on the characteristics of the culture industry, deliberate substantial measures for nurturing companies and human resources in the local regions, and formulate a system in which the local dominates and the center supports.

Urban flood damage has been caused by drainage deficiency. One of the methods to solve this problem is to construct detention basin and Pumping station and to pump out the water to the river. However, because of rapid urbanization, the capacity of drainage pipelines is sometimes not sufficient enough during the rainy season. Therefore, even though we have enough pumping stations, the inflow of surface water never reaches to the detention area, causing floods in urban area. This research is to find improvement of urban drainage system, estimating drainage pipeline risk. Also, eight models for a computer program were developed for practical use. The models were verified changing precipitation duration, intensity, design period, time distribution model, and etc. This verification was processed focusing that the model can regulate the water level in the detention basin and minimize the effect downstream. As a result Fuzzy models were found to be efficient to lower the water level in detention basin, and decreased about 8 cm in water level of downstream.

Despite the widespread use of GIS over the past ten years, it has been limited application for regional modeling of pollutant loadings such as sediment, nitrogen, and phosphorus(non-point source pollution), The goals of this study were to: select important processes and parameters of watersheds that contribute to non-point source pollution degradation, develop a ranking model to use the environmental geologic data and verify the model by comparing results with existing water quality data(Chung-ju Lake) for specific watersheds, The GIS database consisted of topography, geology, soils, precipitation, rainfall erosivity, land use, and watershed boundaries. The index(NPSP) for assessing non-point source pollution was comprised in the following three seperate components: soil loss index(SLI) assesses the potential soil erosion and sedim-ent delivery from field to stream; run-off potential ratio(R.P.R) predicts the potential production of surface runoff; chloropgyll-a index ranks the potential manure(animal or human) production within a watershed. The GIS model was a valuable tool to assess the impact of environmental pollation in watersheds.

The demand of urban land in the Capital Region will be increased by the national economic growth of Korea. However, the available land for residential, commercial, and industrial should be limited in Capital Region, and the system of land supply for the urban land doesn't work effectively in the Capital Region. This research aims to forecast land demand in Capital Region based on the analysis of number of residents as well as housing units, and to suggest desirable land supply directions based on the analysis of land supply regulations and controls. This research concludes that it is demanded $293km^2$ of residential site for the construction of 1.27 million housing units by the year of 2010, and the change of land use from agricultural to residential is very restricted so that it may not supply urban land flexibly and appropriately. Thus, it is necessary to improve not only the system of land use controls but also cooperation among public agencies for the rational operation of land supply system.

In this study, Community Garden of various national and international practices trends to an advanced research, the concept of community garden participated with a group operation out of initiative to produce safety food while securing space for the community, ensuring the area that has gone through a new form of active secure urban green space plan, urban renewal movement was defined as the mean. Furthermore, for the purpose of improving the poor welfare environment by attempting to experimentally make a community garden of a disabled welfare house rooftop and how to target its planning and construction process, partnership involvement, business processes have been investigated, such as cost sharing. The whole process including a budget for development of this case was conducted by the Busan Green Trust. Standard Chartered (SC) First Bank's 50% fund share by community chest, participation of volunteers, support of Busan City and Saba-gu, outside of that, sharing parts or trial to participate by diverse partnership of enterprise, public corporation and laboratory, these are the key in developing community garden's model. Established community garden places resulted food production to users of welfare center for the disabled, participating urban agricultural experience program, horticultural therapy, complex community chapter and cultural center. Furthermore, we could find the meaning of rooftop community garden in the point that it is a low cost garden by applying movable and unmovable planters. This study is profitable for improving urban environment, ensuring community chapter and urban green areas, regenerating a city to develop experimental community garden model by using a welfare house rooftop.
