The purpose of this study was to present a guideline for the construction of children park that can create a quality of dwelling and be easily approached and utilized by residents. In order to present a direction of planning, the investigator examined the actual state of children park in low-rise house residential area, and analyzed its general characteristics. And the discriminative characteristics according to the standpoints of planning of children park. The analytic standpoints were classified into the size and disposition of park, the nature of adjacent street and the utilization of park, and the satisfaction and requirement for the internal space of park. The guideline of planning of children park are as follow: (1) The disposition and size of children park: the children park must be disposed convenient use of all the residents. (2) The environment around including approaching streets and facilities around: residents' recognition and access in their everyday life must be considered in relation to the neighborhood streets and surrounding facilities. (3) The composition and utilization of internal space: the internal space must support all the activities of users, and reflect users' requirements in order to induce them to use it continuously.

The purpose of this study was to evaluated noise environment of the low-rise multi-family house in Athens, Georgia. The results of this study can be applied to the prevention of noise when planning multi-family houses, roads and cities in Korea. The subjects of this study were the place of 1m, 10m, 50m, 100m from 4-lane road ofT apartment and 233 residents lived in the low-rise multi-family houses in Athens. The results of this study were as follows. 1. The average noise level at 1m, 10m, 50m and 100m was 55.5dB, 46.7dB, 43.0dB, 43.0dB and 41.2dB respectively from 4-lane road of T apartment. From the view of the standard in this study, the physical noise was good. 2. The results of the residents subjective response on the noise were as follows. The external noise residents felt - that was a noise by operating machines, and traffic noise - ware as 2.57 on average. The noise by the daily activities, the noise of nature are a little as 2.38 on average. They were disturbed a little by the external noise. They felt the solid born sounds(average 2.49) more than airbone sound(average 2.23) by the internal noise. They are suffered worse from noise in summer and they worse from 8-12 oclock due to external noise and 16-20 oclock due to internal noise. Comparing the noise environment of Korean with that of American, I found a meaningful difference of nature and the noise of daily activities of external noise and all internal noise.

This study presents application effects of hybrid seismic isolation system to realize high seismic performance for low-rise lightweight buildings through a non-linear analysis and onsite experiments. The complex seismic isolation system applied in this study is a method of mixing sliding bearing and laminated rubber bearing in order to overcome limitation of laminated rubber bearing in increasing natural period of the whole seismic isolation system. As a result of the non-linear analysis, seismic isolation buildings designed with complex seismic isolation system are safe because its maximum response displacement is within allowable design displacement even for a strong earthquake which rarely occurs and its maximum response shear is less than design seismic force. As a result of the onsite experiment, the rigidity of seismic isolation stories corresponds to approximately 95.8% of the design equivalent stiffness value. This indicates that actual properties of the whole seismic isolation system correspond to design values.

The number of households in the country is expected to rise from 16,420,000 in 2007 to 19,870,000 in 2030, an increase of 21%. This is because while the population itself decreases due to a low birth rate, the number of households rapidly multiplies with the increase of nuclear family and single-person households. The ratio of single-person household is increasing every year at demographics data. The design that suits their needs, however, is not fully explored yet. The purpose of this study is to find out single-person household's lifestyles, and to search and analyze users' needs for spatial composition according to their lifestyles, and then, propose a single-person housing's plan and direction.

The reason that compulsory removals of a low-quality housing redevelopment such as involuntary or unintentional migration present a problem for urban communities is that whether involuntary movers adapt themselves to their new home has an influence on the urban communities that surround them. Moreover, involuntary emigrants have higher probability of choosing faulty residential areas than voluntary emigrants do. This gives rise to a problem of another residential migration for involuntary movers. In order to solve these problems, there is a need for a new housing policy that enables original residents to come back to their old community. However studies for resettlement had not conducted subjects about housing redevelopment characteristics which influences the involuntary movers directly. Instead personal microscopic characteristics such as statistics of resettlement, the moving distance, the reason of moving, improvement of living environment, had been main subjects of farmer studies. So the purpose of this study is to analyze an analysis of the relationship between resettlement and housing redevelopment characteristics. The data used in this study was obtained at 47 areas designated by Seoul (metropolis) since 1990 for redevelopment. Cluster Analysis Is used for dividing high rate of resettlement with low rate of resettlement and Regression Analysis is used for the analysis of the relationship between resettlement and housing redevelopment characteristics. The results of examining the effects of a redeveloped housing complex on returning residents at 47 areas designated by Seoul (metropolis) since 1990 fur redevelopment are as follows: First, A housing complex with a high returning rate (remove-in rate?) has no state/public land, unauthorized building owners who are in the low-income brackets, and few interested parties such as union members. This is the characteristic of a redeveloped housing complex with a short-period project span. On the contrary, a housing complex that has a low returning rate is crowded by state/public land, and numerous unauthorized building owners, and interested parties. Second, According to the linear regression analysis, among the factors that affect returning residents, 'physical properties(characteristics) of a region', 'population properties within a region', and 'properties of a project span' indicate a negative(-)influence whereas 'properties of a complex density' shows a positive(+) influence. In a nutshell, the more the physical properties, population properties, projectspan properties, the lower the returning rate and the more the complex density properties, the higher the returning rate. In detail, an area with many small land and new/large buildings, a high population, and a long project duration has a low returning rate of original residents while an area holding large capacity and buildings with many number of floors (multiple-storied building) has a high returning rate.

Nowadays, with the perception on residential environment to improve the quality of life, interests in suburban area as a housing area based on the good natural environment has risen, as this area can solve the various social issues and pollutions caused by the overcrowding in the urban area. In the North Western Europe where people have already experienced the industrialization and urbanity, cohousing which designate the modem neighborhood relationships pursuing the common interest has developed, by emphasizing the community activity based on the mutual cooperation while accepting the lives in suburban area. Thus, this study pays attention to 'cohousing' as an appropriate alternative of new suburban residential development and preference of residents of suburban residential development applied the concept of cohousing. For this study, literature reviews and survey on suburban area residents were carried out and general results were provided. Through the survey on the residents in suburban areas, request on new suburban residential development and preferences to cohousing were analyzed. Residents responded that suburban residential development should be planned reflecting the characteristics of the area and considerations on communities are the necessity. They also responded that residential development developed the low-rise housing with low population density. It shows that there will be broad potential consumers for suburban residential development applied cohousing technique in the future.

In 2007, in the city of Chongqing, the city government announced a plan to meet the basic needs of its lower-to-middle class residents, namely those of providing a shelter and urban infrastructure. In one respect, the effort to attain such goals has achieved good quantitative results; however, a more critical examination reveals that little consideration has been given to analyzing the qualitative aspects of such a policy, namely the physical and emotional effects on tenants. The results of the research in this paper have implications on the need to focus on building a 'sustainable' and 'healthy' community, with the awareness that for people in low-rent areas, sociability and community spirit are more closely related to their neighborhood contentment. Although attention to scale and type of area-planning are both important, the immediate surroundings and services are often neglected, but as we shall show they are key considerations for residents in this new type of housing. While attempting to comprehend the role of community in the quality of a neighborhood, in this research, we attempt to document the physical appearance of the problem and explore its underlying causes in order to shed more light on residents' individual evaluations of quality in their local living conditions and include the affective dimensions of such perceptions.

In case of Korean housing complex, there became more mixed arrangement of buildings with different number of layers for a variety of urban skyline, recently. For example, around 33% of the construction sites of 'A' public corporation have gaps of more than 4 layers between high-rise buildings and low-rise ones in the same site, according to the survey. Generally, construction duration of the housing complex is estimated based on the layers of the highest building. Due to this baseline, whole construction duration could be extended so that the project cost could be increased. Therefore, framework duration of higher-rise buildings should be reduced to secure the feasibility of the project. On the other hands, these shortenings could adversely harm the feasibility in some cases because there are a wide range of combinations of the buildings with different number of layers in designing housing complex. Therefore, this study shows the results of analysis on effects of framework time shortening on the cost in housing complex project. Moreover, this could set the baseline of checking possibilities in condensing the construction duration of projects with buildings of different layers by supplying comprehensive database.
