From 1990, Seoul Metropolitan Government has established an urban master plan for the efficient city management by introducing the central place structure with a multi-tiered hierarchy. In the plan, Seoul City uses the strategy of developing the station influence area around the urban railway, in order to form the central place structure, effectively. . Therefore, reviewing impacts of urban railway is the most fundamental study for understanding changes in the spatial structures of Seoul. In the study, we have analyzed the changes in the central place structure of Seoul City with the public land price changes in station influence area around the urban railway at each year of 2000, 2005, and 2010. As a result, we could easily recognize the changes in the hierarchical central place structure by analyzing the time-series changes of public land price in station influence area.

In this paper, we propose a system to detect spatial structures in land cover maps and to detect time-series spatial structure changes. At first, the proposed system detects patches in a certain area at different times and calculates their measures to analyse spatial structure patterns of the area. Then the system conducts patch mapping among the detected time-series patches and decides 6 types of patch changes such as keeping, creating, disappearing, splitting, merging, and changing in a mixed way. Also, the system stores the patch-based spatial structure patterns of time-series land cover maps in binary form to extract changes. This demonstrated that the proposed change detection system can be used as a basis for planning the reconstruction of the urban spatial structure by measuring the degree of urban sprawl.

As a basic study to analyze the relative importance of external space in urban development projects, this study selects evaluation indicators for external space planning and then analyzes systematic external space planning through expert surveys. The scope of the study is to examine the criteria of evaluation items for external space derived from existing studies and to suggest the importance and priority of evaluation items. As a research method, we reviewed the legal and research literature on landscape planning and external space-related guidelines, and conducted a primary review of external space planning evaluation items analyzed by questionnaire. The reviewed items were again reviewed and selected through expert group discussions (FGI). The selected evaluation items were surveyed by expert groups and analyzed in depth using the hierarchical analysis method (AHP). Looking at the relative importance of the calculated sub-items, among the 17 sub-items, 'planning open space' (.096) is the largest, followed by 'pedestrianization' (.082), 'linking with adjacent buildings, streets, parks, and green areas' (.077), 'securing public space through various planning techniques such as linking with pedestrian paths' (.066), 'Plan the placement, form, and scale of buildings in consideration of the identity of the destination' (.065), 'Plan buildings, streets, parks, and green spaces in an integrated and holistic manner' (.065), 'Harmonize with the surrounding environment (landscape)' (.063), 'Harmonize with surrounding buildings and apply landscape planning in urban planning' (.063), 'Entrances and lower floors of buildings are planned as parks for users and pedestrians' (.060), 'Preserve and expand green areas and establish maintenance plans for urban greening' (.054), 'Form the basis for a comfortable life for urban residents by providing long-term development directions' (.047), 'Activate community activities and plan pedestrian environments and streetscapes considering human scale' (.047), 'Establish and propose basic directions for urban greening' (.046), 'Plan buildings, streets, parks, and green areas considering the hierarchy and characteristics of the landscape structure' (.045), 'Plan for integrated land use' (.045), 'Create green axes in connection without cutting them due to development activities' (.044), and 'Apply barrier free design' (.034).

Since it is important to understand the bio-climatic change in Seoul for ecological city planning in the future, this paper gives an overview on bio-climate analysis of urban environments at Seoul. We analyzed its characteristics in recent years using the observations of 24 of Automatic Weather Station (AWS) by Korea Meteorological Administration (KMA). In urbanization, Seoul metropolitan area is densely populated and is concentrated with high buildings. This urban activity changes land covering, which modifies the local circulation of radiation, heat and moisture, precipitation and creating a specific climate. Urban climate is evidently manifested in the phenomena of the increase of the air temperature, called urban heat Island and in addition urban sqall line of heavy rain. Since a city has its different land cover and street structure, these form their own climate character such as climate comfort zone. The thermal fold in urban area such as the heat island is produced by the change of land use and the air pollution that provide the bio-climate change of urban eco-system. The urban wind flow is the most important climate element on dispersion of air pollution, thermal effects and heavy shower. Numerical modeling indicates that the bio-climatic transition of wind wake in urban area and the dispersion of the air pollution by the simulations of the wind variation depend on the urban land cover change. The winds are separately simulated on small and micro-scale at Seoul with two kinds of kinetic model, Witrak and MUKLIMO.

Recently, people in urban areas ask for the creation of space for amenity and improvement of environmental problems, in such a condition the activation and reformation of city have become an important subject. The basic element of a city structure is the street. Therefore in this study, a transition of street spaces of a city was investigated. This study will be a basis for the planning of urban space in order to realize a comfortable and fascination urban life. In this paper, the study areas chosen were "Ginza", "Kyobashicho", "Nihonbashicho", "Honcho", "Tsukizi", "Hatchoboricho", "Ningyocho", "Ningyocho" which are the central places and business areas of capital Tokyo of Japan. The main streets were chosen for investigative subjects because they were planned as making a division of block in a city planning. Using maps and references the data was illustrated and the investigation was focused on the period from the Edo era to present time. (1) A periodical division for the basis of a street transition. (2) Consideration of methods in a plan and design for street spaces in each period. (3) A special feature and process of a street transition in each period. (4) A structure of a street and a construction form. (5) A classified structure of streets. (6) A process of a transition for each street.

This study puts its purpose on presenting an integral system of representative urban landscapes, public design and colors, in practicing urban design in the context of local identity. An integral design of public design that successfully plans and executes local identity, and changes recognition of integral management of urban design, is suggested as followings. Firstly, when the catchment area is divided in metropolitan area, it should be reset according to the natural environment condition regardless of administrative area system like city and county. It is the method to classify the metropolitan area by researching and analyzing geographical condition, weather condition, soil and vegetation in detail and subclassify it by the visual commonness of natural environment. Secondly, it is necessary to access the urban landscape, public design and urban color from the overall aspect emphasizing the plan for each field and local identity. They should be practiced by the role and category of each field on the basis of consistent design strategy and instruction but the cooperation system is required as a process to reinforce and specify the mutual limit. Thirdly, the artificial structure is constructed through artificial adjustment depending on the urban formation process and the development time point. Therefore, it is necessary to pay attention to the rapid urban development, the change speed and the landscape formation of each age. It is necessary to classify the type of artificial landscape by age and form similarity and separate the area that should be generalized and controlled by entire metropolitan area form the area that should be specialized by basic local government.

Multi-family housings caused several problems related to physical form such as isolation of housing estate, inhumanity of the exterior space, and mismatch with the urban structure. To handle these problems, the purpose of this study is to analyse density elements which have a direct impact on physical forms, thereby understand the characteristics of physical form and also identify a meaning of inter-relationships between them. Therefore both formal constituents and density elements are reformed into respective analyzing indices. From the analysis, physical form and the spatial layout of buildings were more uniform in large-scale housing estates than in medium or small housing estates. However, small-scale housing estates showed various form and the spatial layout of buildings in order to increase the building density.

The relationships between fashion and architecture have been interactive. Since the fashion has had the role to decide the structure type of urban environment, it is becoming the new sign of space boundary. This study searches the social and cultural characteristics of Nomadism and the relationships among all kinds of changing objects. After then, the module system characteristics are meditated by analyzing the composition method of module system in architecture. Moreover, the study examines the aesthetic values in the fashion and body architecture from artistic aspect. Based on the above discussion, the followings are the characteristics of body architecture as the social structures expressed in modern fashion. The liquidity is the fluid form of dynamic structures. It shows the extended space form which produces the continuity. The transformation is the variable structure by module system and it forms the diversified structural combination. The movement combines the controlling function to be able to regulate and move freely the body related objects. The convergence is the text combination interpenetrated mutually in enlarged space. Through this, the non-linear continuity and the access of the individual factors are shown.

This study measured the centripetal force and effective scope of the population spread from urban center and subcenters in order to diagnose the urban spatial structure of the formation of a multicentric city structure in Busan. The study analyzed the variability of the determination coefficient value (R square) with a negative exponential function derived from the population density model by extending the circular region into 5-km units. The aim of this study was to measure changes in the effective scope of the population centripetal force of the urban center and subcenter in 5-year intervals from 1995 to 2005 using census data. The explanatory adequacy of the population density function was examined with the bias of the function to calculate the distance error between the real location of the urban center and the optimal location, according to the population density function. To summarize the results, the value for the area of Jungangdong showed a continuous reduction, whereas Seomyeon (Bujeondong) maintained explanatory adequacy without a large change. As a whole, Busan was in the process of continuous diversification, in spite of its reduced population. Therefore, it appears necessary to strengthen the function of the urban center and subcenter and to supply adequate dwelling zones close to downtown to form a more efficient urban spatial structure. The results of the present study will be utilized as basic data for the formulation of a political approach to the efficient reorganization of spatial structure by correlating concrete spatial information with the population variability of Busan's urban center and subcenter.
