Greenbelt was designated by Korean government to prevent indiscreet urban sprawling for 14 large cities in 1971. Importunate claims on deregulation of greenbelt system was continued in these days. But, ecological role of greenbelt as fundamental information for balanced decision making was not clarified sufficiently yet. In Ulsan metropolitan area, we clarified the roles of greenbelt system and prepared the sustainable management and improvement plans by analyzing ecological characteristics of vegetation established in Greenbelt and its surrounding area. Decrease of forest cover in greenbelt was lower than that of exterior and interior of greenbelt. Fragmentation patterns of forest cover corresponded with the pattern of forest cover. NDVI of greenbelt was higher than that of inner greenbelt and similar to that of exterior greenbelt. Surface temperature showed similar trend to that of NDVI. In consequence, greenbelt system has carried out well its primary roles. To mitigate negative effects from urbanization, we discussed management and improvement plans to promote ecological quality of greenbelt and urban landscape.

This study aims to examine the characteristics of traffic accidents involving elderly drivers with regards to the urban structure in Seoul, South Korea. To this end, this research analyzed the traffic accident data of the year 2015 collected by the Korean Police Agency and Koroad(TAAS). The traffic accident records being collected in a spatial unit, spatial heterogeneity and non-dispersion are prone to occur. In order to prevent this, this study employs ordinary least squares regression(OLS), a conventional spatial model for analyzing accident data, and geographically weighted regression(GWR), which is an alternative to the spatial econometrics model. It was revealed that the GWR model has a better goodness-of-fit than the OLS model. According to the GWR model, the population aged under 20 ratio and the industrial area ratio are negatively associated with traffic accidents in which elderly drivers are at fault. Meanwhile, employment density, commercial area ratio and the numbers of subway stations, bus stops, intersections, and traffic islands are positively associated with the traffic accidents involving elderly drivers.

Recently, the harbor has lost its original landscape of the coast and its port-space identity due to the scale expansion through landfill and uniform landscape planning. It also made it difficult for people to access. And the purpose of this study is to provide a standard of spatial size for the development of hydrophilic space of harbor and comfort and familiarity to users. According to the method proposed in the study, the size of the surrounding space was 40,000~150,000m2. In order to compare the spatial scale of the various natural villages, the result of the square conversion was 200~400m. This result is a length giving intimacy according to the theory of distance segmentation. It is difficult to simply define the attributes of the space that can be familiar with it. However, in a sense of space where humans perceive space of a certain size as one space, it is judged that distance is directly related to the recognition of scale. Therefore, if the results of the study are utilized, it will be helpful to create a traditional port space considering human scale and create an attractive landscape.
