This study was conducted to guarantee elderly housing for the increasing number of elderly people over 85. It examined their preference of living with their children and continuously living in their current houses when they reach the age of 85. First, research shows that 69.8% of the elderly wish to live separately from their children in later years. Second, 61.9% of the elderly wish to continue to live in their current houses. Third, the elderly without a spouse, with lower levels of education and with a longer period of time in their current houses, prefer to live with their children. Fourth, the elderly who own a house, who have lived in their current house for a long time, who have a religion and who are satisfied with their houses, wish to continue to live in their current houses in later years. However, most of the houses have safety defects such as a difference of floor-level at the entryway, lack of gas and smoke detectors and slippery bathroom floors. Thus, the elderly need to be supported by providing proper housing renovations for their safety and wellbeing.

Myungji Housing Complex is located in the Nakdong River plain in which the Busan soft clays are developed. It has thick soft soil laver of about GL(-)50m including loose sandy layers, upper and lower clayey layers. The clayey layers have been being consolidated since the land reclamation was completed to build the place for Housing Complex(Apartment) in 1997. Therefore, as one of a series of advance preparations of this project, study was carried on the geotechnical characteristics under the foundation The first part of this paper represents a brief geological history. Then, geotechnical characteristics of clay was analyzed in the classical developments in soft clay. They were based on the geotechnical data obtained by site investigations performed from 1992 to 2005. Finally, we evaluated the average degree of consolidation at this point in time and the residual settlements of upper clayey layer using dissipation and oedometer tests for this project

In many very high density cities in Asia in which there is limited area to expand, growth is forced upward as well as outward. Densely packed detached houses and low-rise buildings are replaced by lower density high-rises, leaving open spaces between high-rise buildings. Through this process, areas that formerly did not have much green space gain valuable green spaces, and new ecological corridors and patches are created. In this study, the demographic and housing-type changes of Wonju City were delineated using land use maps, aerial images, census data, and other administrative data. Green area changes were calculated using land cover data derived from multi-year Landsat TM satellite imagery. The values were then compared against demographic and housing-type changes for each administrative unit. The overall results showed a decrease of forested area in the city and an increase of developed area. Urban sprawl was clearly visible in many of the suburban areas. However, as expected, we also detected areas in which greenness did not decrease when the population greatly increased. These areas were characterized by residential building complexes of ten or more stories. If an equal number of housing units had been built as detached houses, these areas would not have kept as much green space. Our research result showed that high-density and high-rise residential structures can offer an alternative means to protect or create urban green spaces in high-density urban environments.

The purpose of this study is to consider the community design applications in the senior collective housing in Hyogo Prefecture, Japan. It was performed by two programs, application program and space design program. The former is focused on the participation of residents to the planing and design process, sharing, community activity, social interaction, and management by residents. The latter is focused on the common space(room) design. It was also performed by literature review, observation, and interview. The findings for the community design as an application program in SCH are almost the same with those in CH. But, the level of common meal and common laundry in SCH is lower than that of CH. And space design program is focused on the location and scale of common space(room) which is related to the number of users. As a result, the positive possibilities of SCH as a new residential type for the self-reliant seniors can be confirmed. The difference of community design application between CH and SCH is caused by various factors such as senior's health conditions, economic factors, and Japanese life style.

The Purpose of this study was 1) to analyse the attitudes about Elderly Assisted Living (EAL) among urban Korean 2) to consider the policy implications for elderly communal housing. The research methods used were 1) social survey research with questionnaire to find attitudes and preferences about EAL among potential elderly client in Seoul, Korea 2) interpretative suggestion for appropriate policy implications to facilitate developing EAL in urban Korea. A questionnaire was used to find attitudes/preferences about EAL was adapted from the results of the review about communal housing in the UK. The survey was undertaken from September to October, 2000 in Seoul, Korea. Data was collected from 413 subjects and analysed using various statistical techniques. From the results, location should be differentiated into urban type and suburban type. The urban type would prefer around 5 stories multi-family house style with elevator and suburban type would prefer single detached house style with shared garde. The most preferred characteristics found by factor analysis were factor I named as communal facilities and environment(the items belong to factor I was neighbour environment, communal spaces and facilities, heating system, and elevator). The most important advantages of EAL were social activities and convenience. The most salient disadvantages of EAL were difficulty of family contact. The higher the occupational status and income, the lower the preference for the characteristics of EAL with a preference for finding appropriate living arrangements in present housing market. But the higher the educational level, the higher the degree of preference for the characteristics of EAL.

In a planning stage, the assessment system is required to select the proper alternative, reflected the environmental affects such as energy, $CO_2$ and $SO_x$. Unit of energy consumption, $CO_2$ emission and $SO_x$ emission among various assessment systems could be effectively utilized to select the better alternative among various building types. But researches for these areas has not been conducted systematically, but limitedly and sporadically. In this paper, it aimed at providing the unit of energy consumption, $CO_2$ emission and $SO_x$ emission to evaluate the environmental affects between the steel-structured apartment building and wall-typed apartment building. For this, the input-output analysis could be utilized in the construction stage with two-type apartment housing. This approach can be utilized to compare the various alternatives in aspect of the energy consumption and the environment affect, and to select the relatively better alternative. This study found that the unit of energy, $CO_2$ and $SO_x$ of the steel-structured apartment building is lower than that of the wall-typed building

In order to develop a manual of residential alterations for the physically disabled, this case study was accomplished to analyze and evaluate residential environments and residential alterations for physically disabled women. Twenty-nine physically disabled women in Seoul and Kyunggi areas were the subjects of this study. With the evaluation checklist on physical environments of their housing, data on general characteristics of wall, floor, and all features and equipments and spaces of bedroom, kitchen, bathroom, living mom, entrance and balcony were gathered. Also, data on residential alterations were gathered through personal interviews. The data were collected from July 18th to July 25th in 2000. Frequency, percentage, and mean were used to analyze the data. In kitchen, small space, hee space under the sink and heights of the lower cabinets were not properly provided. In bathroom, door width, direction of opening door, adjustable height of shower, level difference, clear space for wheelchair user, and storage place were not appropriate to the disabled. Kitchen and bathroom showed high frequencies of alteration. But most of the subjects were not satisfied with the alterations of their housing. They also wanted to alter these two spaces in the future. In order to after their housing effectively appropriate information of the residential alterations was needed. If a guide or manual book for residential alterations was provided, the physically disabled people will more easily after their housing for safe and independent life.

In this study, traditional treatment scenario of food wastes that collected and transported food waste is recycled in large treatment facilities and suggested treatment scenario of onsite zero discharge system that food waste is treated in housing complex were supposed. The scenarios were compared and analyzed by capital expenditure, oil consumption, $CO_2$ emission quantity, operating expenditure and management expenses. The capital expenditure, oil consumption and $CO_2$ emission quantity of small scale dispersion dealing method is the lowest compared to traditional treatment method. As a results, it is possible to obtain the effect that operating expenditure was reduced by 91% and management expenses was reduced by 40% with suggested treatment method. The treatment method that have low capital expenditure is tend to lower oil consumption and $CO_2$ emission quantity. The small scale dispersion dealing method have the lowest capital expenditure, oil consumption and $CO_2$ emission quantity and the linked method with sewage treatment have the highest expenditure and $CO_2$ emission quantity. Eventually, the optimal model of onsite zero discharge system in housing complex is small scale dispersion dealing method.
