The aim of this paper is to define major factors influencing land development of each of major uses (residential, commercial, industrial) in the process of rapid urban expansion. The main hypothesis of this study is that land use changing patterns are directed by supply side of land managed to public policies rather than demand side. The graphic analysis is applied to relationships between urban growth and land development process of each use and between land development project managed to public policies and land development process. Public and land development projects and zonning protection seem to be major roles of land supply and main determinants of urban spatial structure. Location factors for land development of each uses are selected in 23 variables. Factor analysis is applied to test correlation between variables in 1971 and 1981. Factor structure between two years is similar, but progressive processing of functional separation is derived such as intensive land use is grouped, different location between residential and industrial use is deep. Dependent variables are standardized to logarithm of land development of each use per unit vacant land in two periods, between 1971 and 1980 year and between 1981 year. Correlation analysis between 6 dependent variables and 23 location factors in each years are applied. Major factors of each use are selected in criteria such as high correlation with dependent variables, low correlation between independent variables and common application in two periods. As the result, major factors for residential land development are Land Readjustment Project (LRP), percent of total zoned area in residential zone, residential floor space density per available area, percent of total area in industrial use; for commercial development is distance to CBD, percent of total area in commercial use, residential floor space density per available area in each year, and volumn rate of industrial use; for industrial use is percent of total area of industrial use is percent of total area of industrial use, Industrial Estate Project (IES), LRP, and distance from CBD. Land development pattern of each use between two periods are slightly different. So 6 equation is derived from appling backward method of regession. Adjusted multiple R squares of all is more than 0.5 and those equation is statistically significant and valuable to assist urban land use forecasting.

This study analyze the architectural space in the aspect of the 'Raumplan' and 'Plan Libre'. These concepts based on the 'Raumplan versus Plan Libre' exhibition in Delft University, Netherlands. It is generally agreed that the concept of 'Plan Libre' in connection with Le Corbusie architecture and 'Raumplan' related to Adolf Loos's works. that exhibition contents was focused an extent of modem architecture. But, These concepts continually influence contemporary architecture and offer diverse vision in architecture. Therefore, this study focused on the analysis that look for common element in the space through the case study and space element connection in change of the values, technical growth. This Paper reveals that Adolf Loos's Raumplan is similar to Louis I. Kahn's 'Room' concept and Ando Tadao's centrifugal space composition method In the dwelling architecture. And the concept 'Plan Libre': non-definitive formal system and the elements : column, free form screening wall is revived as formal application of 3 dimension composition in architecture. and transfer lots, void, and linear space in Rem Koolhaas's urban design projects. These aspects is so called topology. This topological concept is an attempt in view of the space connection state rather than formative viewpoint.

In order to increase the utilization of limited space in urban area, it can be a good solution to make use of underground space. For the last few decades, underground space systems, such as underground passages, subway stations, and underground shopping arcades, have been constructed in many cities all over the country. Despite of the advantages on the utilization of space in urban area, underground space systems have always been exposed to the risk of inundations resulted from severe rain storms. In this study, it has been examined to apply 2-D flow models (TUFLOW and FLUMEN) to establishing the preventive measures to the risk of flood. For the part with relatively complex configuration, such as a corridor junction, 2-D flow models present the detailed information about the effect of geometry on the inundation events and the temporal and spatial distribution of inundation over the space. From the result, it can be concluded that the 2-D flow model can be the effective implement for establishing the proper measure to the inundation on underground space systems, which generally have relatively long and narrow geometry with complex inner configuration.

Forest area was applied as health promotion place for resident. Korea Forest Service set the term of "forest healing" based on the application of forest area as health promotion, which multidisciplinary approach in forest policy, and construct the "healing forest" for the healing space. Handicapped was excluded from the forest healing service as healing forest was located in the point away from urban area. The standard of healing forest size was difficult to set as urban forest area was fragmented. This study conducted on adequate standard of healing forest size in urban region. This study surveyed the laws related to the outdoor recreation place, and the walking range of the handicapped (elders, disabilities). The results were deduced with interrelationship between two factors(forest policy, human walking range). Healing forest size was not departmentalized for urban area compared with the standard of similar outdoor space (tourism complex, urban parks). Healing forest size was changed from 50ha to 25ha in national forest, from 30ha to 15ha in private forest considered with walking range of handicapped. This study contributes the evidence as the standard of healing forest size for health promotion in urban resident.

Korea's latest quantitative urban development led to a result to lose our public properties' identity provided by urban environment, so we now have to think how to solve environmental matter of one-sided public design. Because one city's public environment is the central axis to determine its first impression and also connected with its overall value, the region's value show obvious differences by its urban scape design. Therefore we analyzed current cityscape of Tokyo's Marunouchi street and Avenue des Champs-Elys$\acute{e}$es in Paris which applied how to connect visual and physical characteristics of urban space representation to outdoor space's nature well, and tried to reconsider what is our design identity of creative cityscape.

In order to prevent indiscreet urban growth and harmonize urban development with environmental preservation, it is strongly required in Korea that urban planning should be reasonable and transparent. From this societal demand, the urban planning system was changed to be strengthened for the establishment of harmonious land-use order in urban space. However, implementation of the urban planning system demands a lot of information to analyze and estimate the present condition and problems of urban area. For this purpose, the information should quickly be collected, managed and analyzed. The urgent demand of information in urban planning field is able to be fulfilled with recent GIS and its relevant information technique, which can quickly, accurately and conveniently collect various spatial and statistical information, systematically analyze and manage them, and visually present the result of spatial analysis. This study suggested a urban planning information system and its basic implementing scheme to support the urban planning system with GIS and presented a development model of the urban planning information system using the recent GIS and its relevant information technique.

Recently, 2D GIS technology is applied for urban facility management. However, urban facilities are located in 3D space and the information loss is occurring during data abstraction from 3D urban facility to 2D object. Also, the number of urban facilities is increasing steadily and most of urban facilities are located in underground space in the city. Therefore 2D urban facility management system has a limitation on visualization and management for a large number of urban facilities. In this paper, a multi-dimensions urban facility management system based on multi-texture technology is proposed. The proposed system reduces the information loss and improves the readability of information by visualizing urban facilities on 3D virtual space. A multi-texturing technology is applied for integrating of 2D vector data and 3D raster data, and a multi-thread technology is used for improving speed and performance of the system. The proposed technology can be used as a guideline for urban facility monitoring as providing visual information of a facility status with 3D image and facility data.

Purpose: While medical standard is rapidly improved, welfare of users and employees in hospitals is not treated correspondingly. Intercommunication of hospital users is thought to be very important for their welfare, and provision of conversation spaces within hospital environment needs to be expanded by architectural design. Space organization methods for the design of conversation space is to be embellished. Methods: Literature and hospital designs are analysed in order to develop the basis of argumentation for the hospital conversation space. 15 hospitals are reviewed and designed spaces for the intercommunication of the users are examined, Space organization efforts and design experiments are identified, and 6 organizational methods are proposed such as: 1) reducing territoriality 2) flowing space 3) categorizing and separating spaces 4) height variation 5) contact with outside and 6) Sun-lighted space. Results: 6 organization methods are confirmed in precedent hospital cases, and these proposed methods are applied in a new hospital design project to verify their usefulness. Implications: A hospital design project is presented based on these proposed methods of organization for the conversation space. Outcomes of this study can be applied for the formulation of human intercommunication spaces in other facilities.

Urban expansion, particularly converting sub-urban areas to residential and commercial land use in metropolitan areas, has been considered as a significant signal of regional economic development. However, this results in urban climate change. One of the key impacts of rapid urbanization on the environment is the effect of UHI (Urban Heat Island). Understanding the effects of urban land cover change on UHI is crucial for improving the ecology and sustainability of cities. This research reports an application of remote sensing data, GIS (Geographic Information Systems) for assessing effects of urban land cover change on the LST (Land Surface Temperature) and heat budget components in Ho Chi Minh City, where is one of the fastest urbanizing region of Vietnam. The change of urban land cover component and LST in the city was derived by using multi-temporal Landsat data for the period of 1998 - 2020. The analysis showed that, from 1998 to 2020 the city had been drastically urbanized into multiple directions, with the urban areas increasing from approximately 125.281 km² in 1998 to 162.6 km² in 2007, and 267.2 km² in 2020, respectively. The results of retrieved LST revealed the radiant temperature for 1998 ranging from 20.2℃ to 31.2℃, while that for 2020 remarkably higher ranging from 22.1℃ to 42.3℃. The results also revealed that given the same percentage of urban land cover components, vegetation area is more effective to reduce the value of LST, meanwhile the impervious surface is the most effective factor to increase the value of the LST.
