In modern Asia major cities had same problem with lack of affordable housing for families. So they had to concentrate to the mass supply of housing and made some physical counter effects like high density of cities, limitation of parking space. Also people who lived in those cities could suffer from broken traditional community culture. To rebuild traditional community and increase land usage, Block housing is suggested as a new kind of multi-family housing for old town redevelopment. Now some governments are trying to make urban code to give some initiative for new block housing development in old city blocks. They expect this new housing type can help to solve serious problems like lack of parking area, green space and context of block. Also they hope that block housing development can help to increase safety of town and reduce cost of development. The purpose of this study is to review the establishment and development process of Block Housing and to confirm the aspect which has been changed with urban organization together. Also this study tried to find out the intentional characteristics of similarities and differences with comparison of Korea and Japan. And as a result we could find critical physical viewpoint, and provide considerations for future study and plan. Several cases of block housing in Korea and Japan were reviewed for comparative study and Post Occupancy Evaluation (POE) survey was examined to find satisfaction factors and problems which were expected to improved.

To assure the safety of urban railway train, it is necessary to observe the specified driving principles under an essential condition during running on tracks. These principles arises from a great deal of experience for a long time and include safe distance between trains, the railway signaling, block system, regular block of the highest priority and driving prohibition of simple railway vehicle in the main track, etc. Therefore, it is important to apply these principles to domestic urban railway driving regulations and railway vehicle driving regulations. However, domestic urban railway administrator established his own operation rules within the regulation. In this study, domestic urban railway administration's own rules are examined and the appropriate driving regulation on the safe driving principles is proposed.

This paper aims to investigate the design characteristics of a single housing block which is increasing in urban areas. For the analysis, all cases of single block housing in Daejeon metropolitan city were gathered into a database. Main concerns were on the location and the physical characteristics. The results of this study were as follows; 1) single block housing has been increasing both in the new developed areas and the existing urban areas 2) their location has shifted from residential districts to semi-residential and commercial districts. For this reason, the size and density has been increasing 3) the slab block with the hall type and the exterior corridor type were general in residential districts, diverse ones, however, including the point tower type were increasing with unusual circulation types such as central corridor, central core, double corridor, and mixed type in semi-residential and commercial districts 4) there were 5 types of access systems, and especially the street access and the piloti access were increasing, which were related with the high density.

The purpose of this study is to find out the commercialization characteristics of 2nd class residential district in innercity railway station area as basic research to protect urban residential area against the pressure of commercialization. Through the research that are based on literature, field survey and urban planning map, it analysed the commercialization characteristic of selected three sites under similar urban condition; to be a nearby subway station and to be a famous commercial street in site, etc. The consequences of this study are summarized as follows; First it finds the commercialized lots in all blocks that adjoin blocks of upper class zoning. Second it is in inverse proportion between the commercialization of lots and the distance from subway station to residential block. Third, the corner lot of a block and the access road directly connected collector road are very important factors to spread commercialization to residential area. Finally, it finds the difference of the commercialization degree of 2nd class residential zone according to arrange main commercial street and the 2nd class residential block; vertical arrangement and horizontal arrangement.

Thermal phenomena has caused abnormal weather phenomena due to the lack of urban green spaces To solve these problems, the country of recorded a city business is actively evolving trends. but in all the land, most built-up city's green buildings unless the demolition of the composition is an impossible situation, green space in urban areas, with emphasis on composition. In this study, thermal power plants that occured in the evolution of vegetation by utilizing Bottom Ash was tried to develop a lightweight block. Bottom Ash block to take advantage of vegetation is focused create green space in urban areas Vegetation in the block was carried out manufacturing lightweight, porous, lightweight water ratio suitable for three types of blocks selected according to its kind study on the manufacturing and process. Bottom Ash from this study at the time of disposal of coal ash generated by recycling the landfill shortages, loss of landfill costs, environmental pollution and are trying to solve the same problem at the same time.

The purpose of this study is to present the direction of the plan to transform the residential complex into a space that can provide an open residential environment that can lead to social communication and exchange without being closed to the urban residential environment, especially in the apartment complex environment, which is becoming more dense. As a result of the Openness analysis of the 'Codan Shinonome Canal Court', the overall accessibility was good in terms of space utilization, and the openness was low in terms of the spatial composition, which is a physical environment due to the dense block type. When looking at the overall openness of the Codan Sinonome complex in terms of analysis by block, the corrected openness index (C.O.I) for all six blocks was 0.245, the corrected accessibility index (C.A.I) was 1.447 and the openness composite index (O.C.I) was assessed at 1.692. This was due to the formation of high-density block-type urban dwellings and the introduction of S-shaped streets and the layout of low-rise urban support facilities and commercial facilities. The Codan Sinonome Canal Court, which is considered an "open city residence," quantitatively confirmed that it embodies macro-space structure and human-scale space environment even in high-precision environments.

The flood damage has being increased because of urbanization due to the industrialization and the growth of population. Therefore, the hydrologic properties such as increasing the peak flow and decreasing the concentration time of the peak flow have been changed. Hence, the interest of an urban prevention against flood disasters has been centralized at the present day. The objectives of this study is to develop the suitable models to calculate the runoff characteristics from an urban basin. This study describes the properties of each urban hydrologic model and to determine suitable basin model using the ILLUDAS and SWMM models in the urban runoff models in the Yong-Ahm area at Chungju. The peak flow, concentration time and total runoff value of this area are compared and analyzed with regard to calculated and real values. After obtaining values appropriated from the ILLUDAS and SWMM models using 5 rainfall events in this areas, the peak flows, concentration times and total runoff values are compared with real values. As a result of this study, the Transport block of the SWMM is closely shown to real values.

This study explores the issue of campus expansion of an urban university using an in-depth case study of New York University in New York City, USA. It investigates the physical pattern and development mechanism of the campus expansion process on a city grid structure. The three elements that characterize NYU's recent campus expansion, are (1) the university's commitment to building a student community around a public open space on a subway network, (2) four types of property acquisition and building development practiced by the university with private developers for space leasing, building renovation and development under changing local development circumstances, and (3) the city's initiative for attracting the private sector whose development activities influence the university's development dynamics. These findings suggest that the expansion planning of an urban university, due to its location in a city, should be placed on a local planning agenda, which can positively contribute to public goals through the collaborative engagement of the private and public sectors.
