The expansion of human activities and road development has led to the loss and fragmentation of ecological spaces, which is a negative factor for biodiversity. In particular, urban areas where land use and land cover have rapidly changed into urbanization zones are regions where ecological spaces are lost and isolated, making it difficult for wildlife to inhabit. Furthermore, the loss and fragmentation of ecological spaces due to urbanization can have a negative impact on ecosystem services. Therefore, to enhance biodiversity and ecosystem services in urban and national land, it is necessary to establish a practical ecological axis that reflects the current status of the city. Thus, this study analyzed the connectivity of ecological spaces and forest axis that can be used for spatial planning related to urban ecological axis of local governments in Daegu and Gyeongsangbuk-do. The ecological connectivity was analyzed by dividing the Daegu-Gyeongbuk region into 31 local government units, distinguishing between forests and natural areas using land cover data. Subsequently, the study area was divided into 20,483 hexagonal grids of 1 square kilometer each, and the restoration effects for ecological fragmentation within 100 meters were spatially clustered to visualize priority restoration areas. The forest axis was derived by considering regional conditions such as land cover, building area, slope, and others to connect 1,534 forests of 100 hectares or more. The research results are expected to be used as fundamental data for spatial planning, goal setting, and the selection of restoration areas for improving ecological connectivity.

The regional economic crises in the late 1990s and the global economic crisis in the late 2000s had reduced the differences in housing policies among the major Asian economies. This paper attempts to explain and compare housing welfare policy shifts between subsidizing home owning and subsidized renting from the perspectives of the economic and social roles of housing, the lock-in effect of policy processes, and the welfare provision strategy of the East Asian economies. It argues that the impact of economic crises on housing welfare policy in East Asia depended on the duration and the intensity of the crisis and the length and severity of the subsequent economic depression. Another important factor was the role of housing in the economic and social development, especially whether housing market development was considered as an engine of economic growth or revival, and whether the tools of housing policy caused the economic crisis. The loss of impetus for home ownership drive and the new emphasis on rental subsidy provision are new policy trends. Nonetheless, the economic revival since mid-2009 has caused the re-introduction of home ownership subsidies for quenching the housing affordability problems and enhancing home ownership making use of the strong economic conditions.

This study is about architectural design for rural housing block redevelopment for districts with existing residents considering sustainable development. The study suggests development direction focusing on preserving the regional characteristics, and presentation of suburban-style housing complex reflecting on the future tenant's individuality and demand. The preexisting development approach for suburban-style housing complex which was planned by the developer, failed to recognize taste of the future tenants. Profitability being the priority, it also resulted in a serious environmental disruption. In this development however, through a systematic direction for site development and site analysis, conducting surveys through future tenants, attempted for a continuous growth of the community. The study is presented covering the following areas; site's pathway system, nature conservation plan, lot plan, land use, arrangement plan, housing plan and community facility.

The Land Suitability Assessment is mandatory by National Land Planning and Utilization Act and the results are considered in the establishment of urban master plan and urban management plan. The study aims to examine whether the application of Land Suitability Assessment in developed urban areas is appropriate. A simulation analysis based on the Seoul's data of environmental ecological, physical, and spatial characteristics was conducted on urban green, the only applicable land for the assessment in Seoul. The results of the assessment shows that all pieces of lands in urban green is suitable for 'development'. This conflicts to the purpose of land use of urban green which needs to be conserved to protect the natural environment and landscape, animals and plants, environmental pollution, and urban sprawl. In the analysis applying optional indicators such as the distance from the area of Biotope Class 1 to prevent this conflict, the results shows little difference. This supports the necessity to review this regulation including an option to exclude developed urban areas such as Seoul in the assessment.

This paper is performed to study for the plants ecosystems for the rural community forest of designated as natural monument. In addition, it is also proposed the plan of the rural community forest's conservation and restoration for avoiding to the destroy of indiscriminate development such as land-use, cultivation. The rural community forest is a mirror that reflect the regional culture and history, as well as environment. According to this view, undoubtedly, we need to recognise the formative background of rural community forest, the relations between the environment around and the characteristic of plants ecosystem comprehensively. For the purpose of proposing to the plan of rural village forests' conservation and restoration, therefore, this study is: 1) reviews the previous research and ancient documents, and 2) surveys the vegetation structure and the growing conditions in rural village forest directly.

Cities are highly susceptible to disasters due to concentration of population and infrastructure and intensive land use, and there are various factors that affect vulnerability according to regional characteristics. This study analyzed the vulnerability of the heat wave and the surface temperature extracted from Landsat 8 satellite data. Areas with high surface temperature and with high vulnerability did not match. This study overlaid the results of vulnerability analysis and the land surface temperature(LST) in order to identify causes of vulnerability. The results showed that some areas within high-density commercial and semi-residential areas were the most vulnerable, with climate exposure factors, the ratio of the vulnerable populations and residential defective areas being the main causes. Accordingly, alternatives such as green space and residential environmental improvement could be suggested. Various policies for reducing and adapting to heat wave have been established and implemented. However, it is necessary to examine the regional and spatial characteristics of the city, to accurately diagnose the cause of the heat wave, and to prepare appropriate long-term alternatives accordingly.

This study is to identify urban characteristics affecting obesity of elementary, middle and high school students. Most of previous studies in Korea discussed healthy city focusing on adults. We list up possible urban characteristic factors that are considered to affect adolescent obesity from previous studies, and then conduct regression analysis to find policy implications in urban planning. Based on the physical examination data of adolescent students in Seoul from the Ministry of Education, we set the rate of obese students by school as a dependent variable. Urban characteristic variables are set as explanatory variables, and measured by buffer analysis within 500m, 1000m and 1500m. The result of regression analysis shows that the obese rate of students increases with adults' lower education level, higher rate of non-apartment houses, older age of houses and more homogeneous land use. However, the result does not indicate that population density, accessibility to public transportation and the urban park are significant factors for adolescent obesity. Based on this result, urban planning policy for promoting adolescent health should be discussed further.

This paper theoretically explores the calculation of development impact fees focusing on urban growth, new urban development, developer, urban planner, housing, real estate market, community planning, community financing, local government, land use planning, public facilities, and development cost. Many questions related to who bears the burden of paying impact fees beg for answers based on empirical analysis. Those questions involve the extent to which landowners bear the burden, the effect of different levels of impact fees on the socioeconomic mix of communities, the distribution of fiscal benefits within a region where urban communities assess different levels of impact fees, and the preparedness of urban communities to accommodate development displaced by impact fees. Broader questions also relate to how urban and regional form is affected by differential application of impact fees throughout an area and whether money gained from the impact fees makes regional growth more or less efficient. Who ultimately pays development impact fees? There has been little empirical evaluation of how the market responds to development impact fees, but there is considerable information to suggest that, on the whole, the occupants - residents and users - pay the majority of the development impact fees.

We conducted this research to examine how well regional housing prices are suited to use as an alternative to conventional census-based regional deprivation indices in health and medical geography studies. To examine the relative performance of mean regional housing prices compared to conventional census-based regional deprivation indices, we compared several multilevel logistic regression models, where the first level was individuals and the second was health districts in the Seoul Metropolitan Area (SMA) in Korea, for the sake of adjusting the regional clustering tendency of unknown factors. In these models, we predicted two dichotomous variables that represented individuals' after-lunch tooth brushing behavior and use of dental floss by individual characteristics and regional indices. Then, we compared the relative predictive performance of the models using the Akaike Information Criterion (AIC) and Bayesian Information Criterion (BIC). The results from the estimations showed that mean regional housing prices and census-based deprivation indices were correlated with the two types of dental health behavior in a statistical sense. The results also revealed that the model with mean regional housing prices showed smaller AIC and BIC compared with other models with conventional census-based deprivation indices. These results imply that it is possible for housing prices summarized using aerial units to be used as an alternative to conventional census-based deprivation indices when the census variables employed cannot properly reflect the characteristics of the aerial units.

This study empirically analyzed the determinants of the assessment ratio (hereinafter 'AR') based on a total of 2,129 sales cases of forests in Gwangju, Gyeonggi-do. The main findings of this study through multiple regression analysis are summarized as follows. First, this study shows that regional characteristics have significantly different effects on the AR of forest land prices. Specifically, there was a significant difference in the AR depending on the location of the parcel by sub-region and the ratio of residential area, and the higher the number of development plans in progress, the more likely the officially assessed land price will be formed close to the sale price. Second, this study analyzed that location characteristics such as the proximity of the inner and outer center of the jurisdiction and traffic accessibility had a significant influence on the determination of the AR. Third, this study identified significant differences in AR depending on detailed factors such as planning management areas, production management areas, conservation areas for mountain, conservation areas for nature, and restricted development areas as land use and regulatory characteristics of forest lands. Fourth, this study found that land characteristics are a significant factor influencing the AR as an individual factor in forest land.
