The reinforced-concrete multi-story shear-wall structure, which can free a building from beams and columns to allow the planning of a vast room, has increasingly been used in Japan as a high-rise reinforced-concrete structure. Since this structural system concentrates the seismic force onto multi-story shear walls inside, the bending deformation of the walls may cause excessive deformation on the upper floors during an earthquake. However, it is possible to control the bending deformation to within a certain level by setting high-strength and rigid beams (outriggers) at the top of the multi-story shear walls; these outriggers restrain the bending behavior of the walls. Moreover, it is possible to achieve high energy dissipation by placing vibration control devices on the outriggers and thus restrain the bending behavior. This paper outlines the earthquake response analysis of a high-rise residential tower to demonstrate the effectiveness of the outrigger frame incorporating vibration control devices.

This study explores the environmentally innovative and low-impact technology, a zero food waste system (ZFWS) that utilizes food waste and converts it into composts or biofuels and curtails carbon emissions. The ZFWS not just achieves food waste reductions but recycles food waste into fertilizer. Based on a fermentation-extinction technique using bio wood chips, the ZFWS was employed in a field experiment of the system installed in a large-scale apartment complex, and the performance of the system was examined. The on-site ZFWS consisted of three primary parts: 1) a food waste slot into which food waste was injected; 2) a fermentation-extinction reactor where food waste was mixed with bio wood chips made up of complex enzyme and aseptic wood chips; and 3) deodorization equipment in which an ultraviolet and ozone photolysis method was employed. The field experiment showed that food waste injected into the ZFWS was reduced by 94%. Overall microbial activity of the food waste in the fermentation-extinction reactor was measured using adenosine tri-phosphate (ATP), and the degradation rate of organic compounds, referred to as volatile solids, increased with ATP concentration. The by-products generated from ZFWS comply with the national standard for organic fertilizer.

This study aims to examine how residents' perception of Neighborhood in the surrounding area changes to the spatial configuration changes due to co-residential area development in old urban area, and find out the characteristics of the perception changes. The research findings are as follows: First, the results of the spatial configuration changes analyzed by Space Syntax Model show that the integration value is between 0.5 and 0.7, which implies that the development in the old urban area does not contribute to the establishment of hierarchy. When the development takes place with the renewal of streets with consideration of the urban context, however, the integration improves relatively. Second, the actual distance and accessibility due to the street network appear to influence the residents' perception of Neighborhood. After the development, the residents' scope of perception increases on average. Third, the changes in the integration value of the streets after the development appear to influence the residents' scope of perception of Neighborhood. It turns out that there are frequent changes in the residents' scope of perception in the surrounding area around the streets with large increase in integration value, and the perception scope also moves to the center.

This study was motivated by the fact that the current tendency of social integration in apartment complex is not fully performed its functions as a recovery from the community. The purpose of the study is to provide basic data to be useful for living environment of apartment complex, through comparative analysis of residential conditions, community consciousness, and community facility using behavior of residents in national rental housing and condominium. The results are as follows. 1) Condominium's residents have high level of community consciousness compare to the national rental's. Even though both targets were generally above the average, housing and construction standard are required to reconsider for the enhancing of community consciousness of residents. 2) To activate the use frequency of community facility, the development and operation of the community program and the community space and facilities are constantly considered in the follow-up studies. 3) The more residents have high community consciousness, the more they use the community facilities.

Ever-developing information and communications technology has changed the ways of life from that of industrial society to the information-oriented community, and is widely used in a variety of social and economic contexts. Besides, urban problems in today's society are intricately involved so that the possibility of any reliable breakthrough may not to be likely. To work out these complicated problems as well as to understand the crux of the matter more comprehensively, ubiquitous urban planning has been laid out, and as a result attempts to reflect this system are cautiously made in metropolitan areas. However, most u-City planning, integrating uibiquitous technology, has focused on creating urban infrastructure and its services, therefore neglecting the importance of housing in urban space. Consequently, thorough u-City planning has yet to be defined in relation with urban space, and housing planning, established on the basis of the user-oriented housing environment, needs to be urgently made. Centering on the importance of housing in the construction of an improved future urban environment, this study aims to discuss the role of urban environment planning where metropolutan residents can enjoy a comfortable and convenient life. As well, this research paper seeks to focus attention on the consideration for users that is often disregarded but requires reflecting in the u-City planning.

The purpose of this study was to analyze the preference and needs of leisure facilities of residents living in apartment complexes. The questionnaire survey was conducted in the selected apartment complexes, and 676 responses were used for data analysis. The statistical techniques used for data analysis included frequencies, percentage, mean, $X^2$-test, and multiple regression. The major findings were as follows: 1) Subjects needed the diverse leisure facilities such as sports center and resident's self government facilities. And they needed diverse facilities for sports. 2) In terms of location, they needed leisure facilities which was closer to their house. 3) The degree of satisfaction of leisure facilities was lower than neutral. The satisfaction of leisure facilities related with diversity of leisure facilities and program, and poor environment. 4) It was found that the respondents preferred safe and various leisure facilities, and the leisure facilities were exclusively used for the residents only, and the use by non-residents should be charged at the expense. Also, respondents were willing to pay additional fee for the better quality of leisure facilities, and sports leisure facilities congregated in one building were highly desirable.

The purpose of this research is to clarify the valuable industrial heritages of rice mill industry complex remained in Incheon. In order to clarify the formation of integrated historical setting of rice mill industry of Incheon, we analyzed the old map of Incheon's old Jemulpo area and data on address, locations and happenings surrounding rice mill factories and relevant facilities. From here, we could find out the 4 representative rice mill industry area of integrated historical setting and 2 other supporting service area for rice mill industry in old city center of Incheon. Specifically, we could figure out the incremental stages to establish the rice mill industry in Incheon. In the first stage, the rice mill factories were established near foreign settlement area where trading offices and warehouses were equipped. And the second stage reflect the needs of expanding area for Japanese capitalism with the new landfill area. In the final stage, Korean rice mill owners established the korean laborers community near Korean residential area. This formation of integrated historical setting reflecting Incheon's rice mill industry is the identical industrial heritages and urban structures to show the tension and conflict between Japanese and Korean laborers' life in the Japanese Colonial Period.

This paper quantitatively analyzes the investment performance of the environmental improvement fund focusing on the sales effect and the housing benefit effect. The analysis of this study focused on the effects of sales and housing benefits for completed business sites among the business sites supported by the Environmental Improvement Fund. The analysis results are as follows. First, it appears that the sales effect of the completed workplace is effective compared to the amount of investment, so it seems that the purpose of industrial integration of the environment improvement fund is being achieved. Second, it was found that there are variations by workplace and region in housing benefits. This seems to be due to the fact that profitability can be neglected by reflecting the characteristics of residential facilities built by private businesses. The Environmental Improvement Fund is a policy fund that pursues both profitability and publicity. Therefore, it is necessary to transform the structure of the fund to expand support for industrial infrastructure with high publicity. To this end, it is necessary to establish a long-term management plan that equitably considers the profitability and publicity of the environmental improvement fund.

Dormitories of Korean university are planned to pursue qualitative growth after a period of quantitative growth in the 1970s. However, since the 1990s, the physical plan for qualitative growth has not changed significantly and the effects of these changes on dormitory residents has not been verified. The purpose of this study is to identify the environmental factors influencing dormitory life adaptation and to provide a basis for qualitative growth of university dormitories to help dormitory residents adapt to the environment. The research was conducted in three stages. First, the elements of the residential environment of the dormitory complex, which is an independent variable, were derived. The dormitory life adaptation scale was developed to measure the dependent variable. Secondly, a questionnaire survey was conducted to obtain the environmental factors of current dormitory and previous residence and three elements of dormitory life adaptation; 'acceptance of change', 'familiarity', and 'anxiety'. Third, statistical analysis was conducted to determine whether each factor influenced dormitory life adaptation.

There is a high demand for off-base dwellings around Camp Humphreys in Pyeongtaek in accordance with the USFK base relocation project, but their residential planning needs to reflect their requirements. On the other hand, no studies that examined their requirements directly have been found. This study examined the requirements of USFK stationed in Camp Humphreys to identify their requirements. In general, residential planning requires a determination of the demand-based location and size, identification of the facility elements required for the site plan, and analysis of detailed architectural planning elements required for the building plan. Among these, preference analysis of the off-base dwelling demand, location, and site planning elements were performed in this study, and the architectural planning elements were left as following studies. The analysis showed that the demand for off-base dwellings is high, rental houses are preferred, and the commuting time is the most important factor in the location. In addition, while enjoying urban convenience, the location of the foothills near nature is preferred, the importance of the orientation is low and living with Koreans is not a problem. In addition, the demands for exercise facilities in the complex are relatively high.
