This study was conducted to select the location of the logistics center for environment-friendly agricultural products in the Gwangyang Bay Area. AHP(Analytic Hierarchy Process) technique was used to examine location selection factors and factor hierarchy was made through a questionnaire survey and an expert interview for objective and quantitative decision. The hierarchy process of location factors of logistics center for environment-friendly agricultural products in the Gwangyang Bay Area were categorized into five factors such as natural factors, economic factors, social factors, distribution efficiency, and land use plan. Then, those factors were sub-categorized into three factors each. As a result of pair-wise comparison analysis of five categories, the weight of economic factors was the highest, and easy cargo transportation, fitness to higher-order plan, climate, land price, and limitation regulations of sub-categorized factors appeared as comparative evaluation criteria. The priority of the final candidate was decided through this process. While the weight of the Yulchon II Industrial Complex was the highest in natural and economic factors were the highest, the weight of the Gwangyang Hwanggeum Industrial Complex was the highest in social factors, distribution efficiency, and land use plan. The result of the final analysis showed that the Gwangyang Hwanggeum Industrial Complex was the most optimal location candidate for the logistics center for environment-friendly agricultural products.

Various strategies and management plans have been established in order to conserve water quality as well as ecosystem, prevent deterioration of scenic area, and more importantly, retain drinking water securely. However, due to the introduction of numerous small-scale development projects on the waterside area outside protection area of source water and reparian area, river water quality and landscape are severely deteriorated. In this study, We analyzed the expected environmental impacts on the ecosystem, topograph, geology, landscape, water quality according to development type, and assigned different environmental points to each development type depend on environmental impacts, which is able to divide small-scale development project into three categories such as projects with rigorous review, projects with general review and projects with simple review. Finally, we suggested the appraisal basement is to avoid or minimize the expected environment impacts of the small-scale development projects in riparian areas so that make them sustainable development by reasonable restriction.

To accommodate urban concentration of population, multi-purpose super-tall buildings have been introduced, but they induce many travel demands causing regional traffic problems. While several travel demand management policies such as transit promotion or parking limits are presented to alleviate such problems, transportation infrastructure are still insufficient to meet high demands. In this study, super-tall buildings are categorized by scale and purpose, then mode-specific derived demand is estimated using modal share of each category. Optimal transportation infrastructure level is determined by condition-based average changing amount yielded by street network delay (in case of road) or the number of transit routes (in case of transit).

This study analyzed the actual conditions of use of public sports facilities and characteristics of the users of the facilities through surveys and measured the spatial imbalance of the public sports facilities currently supplied by using gravity potential model. This study also suggests evaluation criteria that may be considered for efficient location selection by examining the change of accessibility to the facilities that meet the needs of users in the future. As the results of the questionnaire survey, unlike current usage, the users hoped for badminton, weight training and swimming. And we could confirm the demand for the expansion of the multi - purpose indoor gym which can carry out such activities in the areas. As the result of the analysis on the difference in accessibility of the public sports facility, there were some large variations in the regions. It was found that a balanced supply of facilities was needed in terms of equity. In particular, when analyzing by considering the population estimates of 2025, It is analyzed that the accessibility will be reduced to about 60% compared to that of 2015. In addition, it is evaluated as the best alternative in terms of overall efficiency that the location of the facilities should be in Munsan area where population growth is expected in the future.

Despite recent projects to create urban forests to reduce the levels of particulate matter, objective evaluation criteria for selecting suitable sites for the projects have not been provided. The purposes of this study are to identify assessment items for the evaluation of available spaces for urban forests for the reduction of particulate matter and to analyze the relative importance of the items using the Analytic Hierarchy Process (AHP). We identified a total of 19 items in five categories through a literature review and a panel discussion. A total of 29 responses were collected from surveys given to experts, and an AHP analysis was conducted on the results. As a result, 'locational characteristics' (0.355) received the highest weighted value among the five categories, followed by 'planting type of existing green space' (0.184), 'weather conditions' (0.183), 'physical characteristics' (0.15), and 'human social environment' (0.128). In addition, among all the assessment items, 'proximity of source apportionment of particulate matter' (0.143) had higher weighted value while 'plantation of existing green space' (0.024) had the lowest weighted value. This study will present objective criteria and directions in the selecting of available spaces to create urban forests for the reduction of particulate matter.

Local food industry has been spreading all over the world. Korea is also actively applying and developing local food industry. However, relatively high distribution cost in Korean agricultural market is hindering its further growth. Distribution cost has close relation with shipping distance. Raised distribution cost brings major impacts not only on quality and price of products but also on greenhouse gas(carbon dioxide) emissions. Therefore, it is necessary to find a solution for inefficient distribution system of the local food industry to reduce overall cost and greenhouse gas. In this study, we present a location selection model for local food regional center using Analytic Hierarchy Process. The location of local food regional hub center is decided based on expert opinions on five factors: accessibility, quality, population, size of area, and shipping distance. The relative importance of the five factors has been concluded as follows: quality (0.430) ${\gg}$ population (0.262) ${\gg}$ travel distance (0.201) ${\gg}$ accessibility (0.075) ${\gg}$ and area (0.033). We apply and analyze the environmental management system model for Local food industry to develop the regional hub center site selection criteria and to analyze the effects of greenhouse gas emissions in the local food industry. This study, by applying and analyzing the environmental management system of the local food industry, is believed to be a valuable asset for managing greenhouse gas emission in the local food industry. Also, the data will be used for the autonomous local food industry's direct sales stall management. Eventually, this study will contribute so greatly to the local food industry's competitiveness that even large distribution companies will give way for the local food industry.
