A spatial simulation model for rural and urban sprawl phenomena was developed with GIS and cellular automata techniques. The model finds out built-up areas invading toward rural areas required for development of existing urban area. Probability of land use change for optimizing the development area was determined using a land suitability analysis method interfaced with GIS methods, based on several criteria in terms of geographic and accessibility factors such as slope of land and distance from city center. Weighting values of the criteria were quantified by an analytic hierarchy process method. For model applicability test, the parameters of criteria were calibrated based on the changes in time series land use data of the test city for 1986, 1996, and 2000, which were classified by remote sensing techniques. Simulated and observed areas in land use maps for city shape of 1996 showed good similarities with each other through a morphology verification method. The model enabled us to evaluate the spatial expansion phenomena of cities considering boundary conditions, and also to simulate land use planning for rural areas in urban fringe.

The purpose of this study is to classify types of urban flower landscape. As a result of the study, first, through literature and case review, it was found that the four elements of place element, form element, natural element, artificial element, should be included in the sentence and key expression for defining the concept of flower landscape. In contemplating these four elements, a newly reconstructed concept of flower landscape was presented. This is expected to be the basis for the flower landscape integration theory. Second, flower landscape was defined as a genre and a unit of urban landscape. In addition, in order to build a system of flower landscape as a specialized area, after considering the concept, characteristics, and functions of a large category of urban landscape, its hierarchical categories with flower landscape were newly arranged. Thus, the flower landscape as an urban landscape was suggested. Third, in order to provide rational selection materials to consumers through type classification, related theories were investigated by expanding not only to the flower field, but also to the urban planning and urban ecology fields. 41 elements for the type classification were extracted, and 4 core elements were derived through the clustering process. Based on the 4 elements as the classification criteria, through the opinion verification from the FGI with experts, 9 types of middle-classification and 30 types of small-classification were derived. As a follow-up research suggestion, if a valid type is additionally established through a monitoring in the type application process, and more specified application types are developed and organized by expanding second-level classification hierarchy to the third-level hierarchy, this will lead to great studies improving the system of the types.

During the development process of mega-project, individual buildings including skyscrapers are built following the master plan. It is not a difficult thing to see the gap of standpoint between the urban planners and architects on the project. This study aims to analyze the difference between architect and urban planner's point of view in evaluating international design competition works which the internationally distinguished honorable design companies(SOM, Jerde Partnership, Studio Daniel Libeskind, Foster+Partners and Asymptote Architecture) submitted as the ideas of Yongsan International Business District Design. Furthermore, we made an attempt to quantify the weight of each factors of urban design by each group. Architect and urban planner's viewpoint were revealed with seven architects and seven urban planners evaluating the international design competition works through AHP(Analytical Hierarchy Process). AHP structure was made of two step hierarchy in terms of Master Plan and Landmark Tower. Eight evaluation criteria were set up such as the concept, land use, transportation, feasibility of Master Plan and the concept, location, functional efficiency and aesthetic beauty of Landmark Tower. Results show that Architect have different point of view from that of urban planner. While the architect's weight of evaluation criteria is on the Landmark Tower(0.505), urban planner's weight is on Master Plan(0.642). Feasibility, the location of Landmark Tower and land-use are very important evaluation criteria to architect and urban planner in common. Functional efficiency of Landmark Tower is in architect's favour and transportation is in urban planner.

In recent years, some experts have shown that urban competitiveness is more important than national competitiveness. They have also argued that innovation will make cities more competitive. The purpose of this paper is to create Korean urban competitiveness index, and to also highlight strategic aspects for enhancement of urban competitiveness of metropolitan cities based on innovation in Korea. First, we will present various factors and indicators of urban competitiveness based on three components for innovation: formation of cluster, human capital, creative economy. Available literature and statistical analyses will be used. Second, scores of urban competitiveness will be developed based on Analytic Hierarchy Process (AHP). Evaluation of scores with weights will be used for this purpose. The resulting weights are 0.3672 for the formation of cluster, 0.3318 for human capital, and 0.3010 for creative economy, respectively. Finally, we present urban competitiveness using the standardized T-score. The most competitive city based on innovation is Daejeon(1st), followed by Gwangju(2nd) and Daegu(3rd). Three least competitive cities are Incheon (6th), Busan(5th) and Ulsan(4th).

It is necessary to study more integrated and objective method of urban compactness evaluation. Accordingly, the author examined precedent study and references related to the theory of compact city with the aim of deducing the urban planning factors from them. And then, these factors are objectified through the survey and interview with experts, and each of the factors is given a weighting by the AHP(Analytic Hierarchy Process) Method. Based on these evaluation model, the urban compactness of Korean Metropolitan Cities such as Busan, Incheon, Daegu, Gwangju, Daejeon, Ulsan, are analyzed their relative gap. The result of this study, as a foundational data for decision-making on the urban policy, could be useful for compact city planning such as regeneration of old town center etc.

After decades of high-speed development, designing tall buildings as critical components of urban habitat, rather than simply standing aloof from their environments, has become an important concern in many Asian cities. Nevertheless, the lack of quantitative understanding cannot support efficient architectural design or urban renewal that targets better place-making. This study attempts to fill the gap by providing a typological approach for measuring the social impact of tall buildings' ground conditions: that is, public space, podiums, and interfaces. The central business districts (CBD) of three Asian cities, Shanghai, Hong Kong, and Singapore, were selected as cases. Typical patterns and categories of lower-level public spaces among the three CBDs were abstracted via typological analyses and field study. The following evaluation is achieved through the analytic hierarchy process (AHP). This quantified approach helps to provide a visualization of high or low positive social impacts of tall buildings' lower-level public spaces among the three cases. This study also helps to suggest a design code for tall buildings aimed at a more human-oriented urban habitat.

Every assumptions on the importance of urban green space were highly valued by urban and land-scape professionals. This paper, therefore, investigated residents' values on urban green space as a first stage study on the role of green space in metropolitan region. Case study area was Taegu city. Questionnaire was main tool for the investigation. This study discussed operationtional defition of green space and the appropriateness of the hierarchy of green space in order to examine the changing role of urban green space in terms of people's values on green space. The investigation proposed that the people's values were quite different from those of the professionals' and suggested the need of new method which was more suitable to investigate people's emotions and values on the green space in the city.

This paper attempts at analyzing the urban dynamics in Northeast Asia by looking at major forces transforming the regional structure of Northeast Asia. Trade and foreign direct invest-ment are identified as two principal channels of increasing economic interdependence in the region. In addition, macro development strategy and infrastructure policy are another set of determining factors for changes in the regional structure of Northeast Asia. To examine the role of cities and inter-city linkages, the paper first tries to identify major urban centers and urban hierarchy in Northeast Asia. Secondly, it examines the prospects for inter-city network formation. Against these anticipated changes in the regional structure and inter-city networks in Northeast Asia, the paper discusses about the future of Korea as well as the role of Koran cities in the regional economy of Northeast Asia.

In this study, the location and network hierarchy of the seven major test and certification institutions in Korea were analyzed. First, like other APS, the test and certification institutions are concentrated in the metropolitan area, and the spatial spread of the branch is developing. Second, unlike other APS, branches do not accumulate in large cities. It is deeply related to regional economic geography characteristics such as proximity to manufacturers and specificity of regional strategic industries. Third, despite the spatial spread, workers are concentrated in the metropolitan area. Fourth, urban-regions are mainly formed between the metropolitan area of test certification and the Chungbuk(Cheong) area.

This study aims at providing basic policy materials to build a basis for supplying and creating urban parks balanced across Gyeonggi province and improving the quality of life of residents through, an extensive analysis of all city parks in cities/counties in Gyeonggi province. The study result showed that first, the number of parks is only 40% of the adequate number and, thus, accessibility of Gyeonggi province residents to parks in neighborhoods is significantly low. Second, a proportion of park types in children's park, neighborhood park, urban nature park is 67% : 24% : 2%, which is adequate in Gyeonggi province as a whole. Third, as for the area of parks per resident, the area of designated park is $17.7m^2$/person, which is over three times of legal requirement in urban planning area ($6m^2$/person). However, created park area is only $5.6m^2$/person, which fails to meet the legal requirement. Fourth, when park area of each city was compared, the areas varied significantly across cities. The Gyeonggi provincial government needs to secure funds aggressively and accelerate setting up and expanding facilities at designated parks located within the current urban areas. The findings from this study should be used as important materials when developing supply & demand policies for urban parks in Gyeonggi province. The study implicates that independent park policies and management by each city/county as well as the establishment and management of a comprehensive park policy at a provincial level is significantly important.
