Korea has experienced a remarkable economic achievement since the 1960s. However, behind this facade of growth and progress, a chronic housing shortage in the capital region, declining owner-occupation, rising housing costs, and polarization in housing conditions between the better-off and the worse-off clearly illustrate the impasse and crisis in housing that Korea now faces. In addition, the IMF crisis and the late global financial crisis shocked the Korean housing market. The Korean government has made significant policy changes to improve housing security for less-privileged groups. In order to achieve housing policy development, the Korean government has tried to employ of advanced countries. What are the benefits(merits) and dangers(demerits) of housing policy transfer between countries? This paper emphasizes that we must recognize about 'differences' rather than 'commonalities' between countries with respect to policy transfer. It also maintains that the government should play a main role as an enabler rather as a provider of 'low-cost' housing.

The Seoul Metropolitan Government is striving to minimize the amount of traffic according to the supply of apartment houses along with the solution of housing shortage for the low income people through high density development near the subway area. Therefore, a stronger policy is necessary to control the traffic of the passenger cars in a subway area for the successful high density development focusing on public transportation, and especially, the estimation of the demand of cars with high reliability is necessary to control the demand of parking such as the limited supply of parking lot. Accordingly, this study developed car ownership forecasting model using Look-up Table among category analyses which are easy to be applied and have high reliability. The estimation method using Look-up-Table is possible to be applied to both measurable and immeasurable types, easy to accumulate data, and features the flexible responding depending on the changes of conditions. This study established Look-up-Table model through the survey of geographical location, the scale of housing, the accessible distance to a subway station and to a bus station, the number of bus routes, and the number of car owned with data regarding 242 blocks in Seoul City as subjects.
Examining Japanese Planning System through the National Territory and Housing Policies: A Focus on Changing Characteristics and Implications

There are similarities between Korea and Japan in terms of national planning and development system and housing policies. Japan has suffered from great shifts of social and economic systems due to skyrocketing land prices for three times and the collapse of the bubble economy after the Second World War. The study reviews historically important changes in the national territory and housing policies for last 60 years in Japan. It also investigates changing trends and characteristics of many socioeconomic indicators with regard to population, housing and other fields in response to these policies. First of all, Japan has experienced significant economic growth before and after the 1960's, and the era of national rebuilding projects in the 1970's. After then, the period of the bubble economy has emerged since 1980; however, it suffered from skyrocketing land values between the late 1980's and the early 1990's, and the collapse of Japanese bubble economy in the early 1990's. In response, many urban regeneration policies and projects were proposed to recover the national economy since 2000. It is found that these national territory development and housing supply policies throughout the country have been influenced by the changing characteristics of social and economic conditions. Since the housing supply ratio in 1968 reached up to around 100% on average, Japan has been focusing attention to improving the residential and living quality for existing housing stock rather than supplying new housing units through large-scale new town projects. These experiences are full of helpful suggestions for our future housing and urban regeneration policies as we reach to more than 100% of housing supply ratio on average.

Such factors as living space, living environments, etc. are considered to have influence on housing satisfaction. Recently, increased residents' participation and residents' conflict in apartment management emerge as the important factors to influence it. They are more important in a social-mix housing complex of sales apartment and rental apartment, which is provided as a part of social mix. Therefore, a study hypothesis is established with a study model based on the precedent studies. The results from investigation the hypothesis are; First, the factor of living environment has meaningful influence on the factors of residents' participation and conflict. Second, residents' participation and conflict significantly affect housing satisfaction. Third, the factor of residents' participation shows a full mediated effect, and the factor of residents' conflict, a partial mediated effect. This study has a meaning as an exploratory one to identify a variable of residents' participation and conflict in social-mix apartment complex, and to verify their influence on houisng satisfaction empirically.

In order to achieve an efficient urban regeneration of the nation, it is required to determine the extent of decline nation-wide and the declined areas for each district and also to evaluate the potentials of the concerned areas. For this task to be accomplished, a construction of a comprehensive diagnostic system based on spatial information considering diversity and complexity is required. In this study, a total information system architecture for urban regeneration is designed as part of the construction of such a diagnostic system. In order to develop the system, a city and district level unit decline diagnostic indicators has been constructed and a decline diagnostic system has been developed. Also, a scheme to promote the advancement of the system is proposed. The DB construction is based on the city and district level nation-wide and metadata for the concerned level is constructed as well. The system is based on the Open API and designed to be flexible for extension. Also, an RIA-based intuitive UI has been implemented. Main features of the system consist of the management of the indicators, diagnostic analysis (city and district level decline diagnosis), related information, etc. As for methods for the advancement, an information model in consideration of the spation relations of the urban regeneration DB has been designed and application methods of semantic webs. Also, for improvement methods for district unit analytical model, district level analysis models, GIS based spatial analysis platforms and linked utiliation of KOPSS analysis modules are suggested. A use of a total information system for urban regeneration is anticipated to facilitate concerned policy making through the identification of the status of city declines to identify and the understanding of the demands for regeneration.

Space extension and the increase of the number of households are helpful to raise business value of the remodeling through the renovation of apartment houses that is required by residents of new cities and large-scaled apartment. However, in the case of accepting this demand, it could have a bad influence on the landscape of a complex in terms of the structure of apartment houses and the safety of construction and urban planning, and a problem occurs in the aspect of fairness for reconstruction. For the study, the current status related to the remodeling system through laws, related articles since 2000 and research data was analyzed. In addition, the individual quantitative analysis was conducted in the four aspects to judge whether households expansion for remodeling is plausible:1) Statistical data to comprehend the changes of population and social structure 2) Survey data of floor space index and the building-to-land ratio of new cities at the intial stage for the review of the effect of architectural planning and urban environment 3) Surveys of experts on structural safety in order to judge whether the demand of expansion is accepted or not. 4) Quantitative analysis of each item to compare fairness with reconstruction. Therefore, this study is intended to understand problems of the remodeling system that is currently operated. Moreover, it will be further reviewed that the expansion of households is feasible through the permission of expansion and it will be discussed that the revitalization of the apartment remodeling has a positive impact on the residential environment.

Recently, the chance of dew condensation in apartment buildings is increasing because of several reasons. For example, ventilation rate has been decreased because of high-insulations and airtightness for saving energy. Besides, the humidity has been made by drying washes, cooking and bathing inside of apartment buildings. However, there is lack of resonable design criteria for preventing condensation in real life and real surroundings. Therefore, this study is aimed at making a resonable design criteria of preventing condensation by measuring the indoor temperature and humidity in real life. In addition to this, it is aimed at making a resonable outdoor condition and classifying regions by using weather data. The following are the results. The interior criterion for condensation was set up
and a relative humidity of 55%. The outdoor criterion for condensation was set up
respectively for the hard frost, middle, and southern areas.

This paper presents the results of performance verification tests of the isolated flat plate apartment building with the laminated rubber bearings. The shaking table test is carried out in CABR(China Academy of Building Research) with two 1/10 scale isolation and non-isolation models under 4 excitation waves. The shaking table test is proceeding from x axis, y axis and x+y axis with different amplitude of acceleration values. The results show that, to non-isolated model, the natural vibration period is remarkably decreased and entered non-linear condition after moderate earthquake. Its accelerations become lager with increasing storey number and completely collapsed under large earthquake. The inter-storey shifts largely exceed the limit values of regulated displacement angles. But to isolated model, the natural vibration period of isolated modal is almost the same in all conditions and still in its elastic condition. The earthquake loading is greatly reduced and the accelerations of superstructure are greatly reduced. The inter-storey drifts are very small and can be neglected. The isolated model is in translational state and can be seen as a rigid whole. The displacements of isolation layer are in the allowable range. This experiment demonstrates that the seismic isolation is very effective to mitigate the influence of earthquake on structures and it is possible to increase the serviceability due to decrease the floor acceleration. facilities from their good states that is superior to non-isolated structure.

Streams and rivers are among the most fascinating and complex ecosystems on Earth. Recently, many plans of ecological streams are developed and performed in several regions. In spite of obtaining of instream water is most important problem to composite an ecological stream, assessment methods for instream water are too various to estimate an optimal result. In this study, we developed decision support system so that decision-maker may can be supported decision making for composite an ecological stream with connecting the satisfaction of residents in stream. Decision support system is composed of hydraulic, water quality, eco-river simulation model and can show optimal instream flow assessment and water quality improvement.

This study was aimed to suggest a management strategy of GHG emissions for the public organizations in land and housing costruction sector. As public organizations' businesses are characterized as 'public' and 'comprehensive', these characteristics should be considered in scoping emissions, setting-up reduction target, building GHG inventory, and establishing management system. Since public organizations' activities in construction sector involve a wide range of social infrastructure construction projects, it is not easy to account their actions to reduce GHG emissions quantitatively. Therefore, this study suggested that a twofold approach is suitable for public organizations in construction area, classifying the measurable reductions and the immeasurable actions according to the their business characteristics. To give a concrete example, a GHG emission management system for the Korea Land and Housing Corporation (LH) was proposed.
