Excessive concentration of population into city has resulted in urban sprawl and environmental deterioration of suburbs in some cities. To prevent our cities from unfavorable situation of urban development, we are greatly in need of understanding of the city's growing appearance in the future. This paper examines an urban growth model of Jinju City. Existing urban growth models elaborated have difficulties in dynamic simulation. Easy geographic visualization and spatial exploration is another hard barriers to overcome. For these reasons we integrate Cellular Automate (CA) as an urban dynamic model and Geographic Information System (GIS) for visualization. Cell-based CA model was programmed with Visual C++ under the transition rules proposed with 1918 to 1986 growing trend of Jinju City. CA model constructed then was simulated as changing parameters into three cases. As a result, a CA model made was proved to regenerate urban growth as high as 93% of accuracy.

The purpose of this study is to overview the situation of U-City development and suggest the U-City strategies in the future. For this end, firstly, the concept of U-City was redefined reviewing the results of other researches and the changing situation of national U-City project. Then the U-City evelopment trend of foreign countries was investigated, which revealed that Korean U-City is only the case that is deploying throughout whole the city area as a nation-wide projet. Next, in the situation of U-City project which is being initiated by central government, law of the U-City development, the background and implications of turning from U-City to U-Eco City, U-City R&D projects were represented. Finally, for the setting the right direction of U-City development, seven issues concerning U-City development were raised and examined. Seven issues included the difference between U-City and informatization project, U-City control & management center, the concept of U-City convergence, U-City standardization, U-City service standard and road map, demand, U-GIS. As conclusion, the discussion here is expected to contribute to develop Korean U-City model to be referenced and exported to the foreign countries. 본 연구의 목적은 U-City사업의 추진현황을 분석하고, 바람직한 U-City 개발을 위한 전략을 제시하는 것이다. 이를 위해 먼저 타 연구결과와 U-City국가사업의 추진상황을 반영하여 U-City의 개념을 재정립하였다. 다음으로 우리나라와 세계의 U-City 개발과 연구 동향을 분석하여 우리나라처럼 국가적 차원에서 U-City 개발을 추진하고 U-City 적용범위가 도시 전체로 확대되는 경우도 우리나라가 유일하여 향후 한국형 U-City개발이 세계적인 표준이 될 수 있을 것으로 기대된다. 한편 우리나라의 구체적인 U-City 추진상황을 파악하기 위해 정부의 U-City 추진 현황, 법률제정, U-City에서 U-Eco City로의 전환배경과 의미, U-City R&D사업의 현황을 검토하였다. 마지막으로 U-City와 관련된 주요한 이슈로서 U-City의 정보화사업과의 차별성, U-City 통합정보센터, 융합, U-City 표준화, U-City 서비스와 로드맵, U-City 그리고 U-GIS의 발전방향 등 7가지의 이슈에 대한 논의를 통해 바람직한 향후 U-City사업의 방향을 제시하였다. 이와 같이 본 연구는 U-City사업에 대한 전반적인 흐름과 이슈의 분석을 통해 U-City의 미래 발전방향을 정립함으로써 우리나라가 국가적인 사업으로 추진하고 있는 U-City의 세계적 모델을 개발하는 데 도움이 되고자 하였다.

The real estate policy to prevent speculation carried out by the government in 2003 is blamed to be a failure because it regulated market too strictly. As a result, Korean economy has fallen down seriously. In addition, the policy is gradually attacked to be mitigated. To avoid confusion in real estate market and national economy, the market needs new tools of assessing the direct and indirect policy impact on the market from various directions in advance. This paper presents a model, Multi-Agent Housing Market Model (MAHMM), to simulate housing market. The model assumes that 1) a householder is regarded as an agent, 2) every agent has its own properties, 3) agents immigrate, make trade or build new houses as surrounding environment is changing, 4) agents find target houses based on the behavior rules established in the virtual space. After running several scenarios, this paper could find out that housing information gives a great variation on market but about 16% of market information was sufficient in searching target houses and forming sound housing market. Next, the number of housing trade and trade ratio increases as the national economy grows. However, the increased amount is not linked directly with the increase of total house number if sufficient market information is given.

There has been increasing emphasis on public participation and collaborative planning over past decades. Several practices on urban contexts highlighted planning paradigm shift from "planning for the people" to "planning with the people". Moreover recent revolutionary development on inter-net and telecommunication technology enabled us to make new participation on-line tools. This paper is about the development of the web-based "Public Participation and Collaborative Planning System (PPCPS)" applied to the railroad removal project in Jinju City. PPCPS consists of 3 phases. The first phase provides information visualized with GIS, photos, video clips, and 2D or 3D. Next is the collection of local information from users. The last stage is the assessment of the alternatives. PPCPS integrates useful tools and expedites public participation through the interaction between users and planners systematically. As conclusions, the influence of our system appears to be positive, though additional comprehensive evaluation is waiting to conclude. This system will contribute to empowerment and democratic decision-making within the community.

Though zoning is a fundamental tool for the implementation of land use planning. It still has unclear decision making process on zoning designation. Zoning once applied on site is hardly amendable. Therefore elaborated quantitative models and simulations under possible scenarios and conditions are needed before the decision. Land use models developed however have hardly been applied to real sites, because of their unflexible nature and uneasy programming. No systems has been introduced for the visual simulation. Thus, powerful and user-friendly system is required. For these ends, Genetic Algorithm(GA) is introduced as a decision model. The GA model integrates scenario building and visualization tools to be a ;planning support systems(PSS)', which allows a user to set the sample areas, change their attributes and model parameters through the interfaces constructed by Delphi 5.0. Through the application to Ulsan City, 'GaSim' we developed was proved to carry out simulation effectively under various scenarios and find reasonable solutions easily.

The purpose of this paper is to develope method to find our location pattern of urban facilities locational patterns are often classified by three types, random, concentration and dispersion type. Considering that the urban facilities are divided into two types also in a sense of spatial dimension, 1st dimensional facilities(i,e. gasoline stands etc.) and 2nd dimensional facilities (not 1st dimensional facilities). classification method is developed according to these two types of urban facilities. Nearest distance concept is introduced and theoretical nearest distances of each type of facilities are calculated. The equaTions to calculate the frequency distributions of the theoritical nearest distances, when facility density is given, are developed using probabilities of appearance of same kind of facilities within unit distance for the first time. And comparing the frequency distribution of theoretical nearrest distance to that of real situation by values, location patterns are made clear whether they are random or not. If not random types, then they are testified whether concentration or dispersion tyoe. This was tested through the case of Chinju City.
