The main purpose of this study is to introduce a new method of evaluation, and to suggest how to apply geographic information system for optimum public facility site selection. For this purpose, a new evaluation model for the site selection is developed. The model provides a simple and easy method of evaluation. It also allows differences among location factors through two step weighting procedures. For a better understanding of the model, solution procedures and visual figures are illustrated with the case of Dalseong-Gun's city hall location example.

Intake ratio from river constitutes about 31% (8/26) that beings to "water stress country" as "Medium ~ High" with China, India, Italy, South Africa, etc. Therefore, the present study on a dam that is the most effective and direct for securing water resources has been performed. First of all, climate change scenarios were investigated and analyzed. RCP 4.5 and 8.5 with 12.5 km grid resolution presented in the IPCC (Intergovernmental Panel on Climate Change) 5th Assessment Report (AR5) were applied to study watershed using SWAT (Soil and Water Assessment Tool) and HEC-ResSim models that carried out co-operation. Based on the results of dam simulation, the reduction effects of floods and droughts were quantitatively presented. The procedures of dam projects of the USA, Japan and Korea were investigated. As a result, there are no estimating quantitative criteria, calculating methods or formulas. In the present study, therefore, indexes for selecting suitable dam site through literature investigation and analyzing dam watersheds were determined, Expert questionnaire for various indexes were performed. Based on the above mentioned investigation and expert questionnaire, a methodology assigning weight using AHP method were proposed. The function of suitable dam (FSDS) site was calibrated and verified for four medium-sized watersheds. Finally, automated model for suitable dam site was developed using FSDS and 'Model builder' of GIS tool.

우리나라의 연 강수량은 약 70% 가 6월 ~ 9월 우기에 편중되어 있으며, 국내 약 65%가 산지로 이루어져 있어 강우의 유출이 한번에 일어나는 특성을 가지고 있다. 이러한 수문학적 특성으로 인하여 수자원 관리가 어려우며, 폭우, 폭염, 극한가뭄 등 기후변화 현상이 심화 되고 있는 것으로 나타나 수자원의 안정적인 관리에 대한 어려움이 있다. 특히, 강원도 영동지역을 포함한 동해안 지역에 위치하며, 경사가 가파른 태백산맥 동쪽은 하천 연장이 짧고 하천의 규모가 크지 않아 지속적인 수자원 부족 현상을 겪고 있다. 우리나라에서는 여름철 홍수기(6월 ~ 9월)에 집중된 강우와 일시에 유출되는 강우를 저장하기 위하여 저수지와 댐을 활용한 수자원 관리가 이루어지고 있다. 용수 부족으로 인한 주민 피해 및 사회적 갈등을 해결하기 위해서는 동해안 지역의 수자원 확보를 위한 구조적 대책 즉, 기존 댐 저수지 중심의 수자원 인프라를 지하댐을 중심으로 한 대용량 지하수 시설과 연계하여 활용하는 지하댐 적지 선정에 관한 연구를 시행하였으며, 적지선정에 대한 타당성을 위하여 전문가들의 설문조사를 통하여 Fuzzy AHP 기법을 적용하여 연구를 시행하였다.

This study aim is to establish the suitability analysis of a constructed wetland using Geographic Information System. A constructed wetland is a flood control reservoir that is able to control flows and conserve a preserving integrity of nature maximum. It has been did that DB construction of flood area, socioeconomic analysis, and space analysis using GIS. Achieved reiteration arithmetic function from results of several elements, it has been did analysis for possibility space of constructed wetland. Through the analysis of flood area and a constructed wetland capacity, it has been established the estimation where is possible to build wetland. This study is applied suitability analysis method where has been choose the basin of To-Phyeong river in Kyongsang-namdo with methodology presentation about suitability analysis.

The purpose of this study was to determine a suitable site using GIS for solar energy harvesting for an administrative district in Daegu, which aims at becoming a solar-powered city. From this result, the ecological housing complex was planned on a solar theme in the real site. For this analysis, various indicators and standards were selected based on previous studies and the indicators were divided into the location, exclusion, and class condition. The results showed that the suitable area was $153.95km^2$ and 17.6% for Daegu area, and the highest suitable area appeared to Dalseong-gun. Finally, using suitable site analysis results, we selected the site of Sinseo housing area in Dong-gu and we planned the ecological housing complex for solar energy. This study can be used as base data for the Daegu solar business and its establishment by considering various indicators for analysis of suitable areas in solar energy. Also, the result of the ecological housing complex plan would be helpful in promoting Daegu as a solar-powered city.

In this paper, we describe a method for the suitability selection on habitable environments of Corbicula Japonica in the Songji Lagoon. Acquired data by in-situ measurements analysed in applying GIS. In order to identify the characteristics of environment in Songji Lagoon, water temperature, salinity, Dissolved Oxygen, and PO4-P were used. This study is expected to use the basic data for Corbicula Japonica breeding in similar lagoon environments.

강변여과는 인공함양을 활용한 대체수자원의 대표적 방법으로 하천수를 충적층으로 통과시켜 간접취수함으로써 오염저감과 수질사고 대처 능력의 장점을 가지고 있다. 유럽을 시작으로 많은 선진국에서는 150년 정도의 개발역사를 가지고 있으며, 우리나라에서도 현재 낙동강을 중심으로 강변여과를 활용한 상수도 공급이 이루어지고 있다. 본 논문은 이러한 강변여과 개발을 위한 개발전 개발전략과 적절한 개발위치 선정에 대한 연구로서 게임이론적 접근을 시도하였다. 강변여과 개발을 위한 지자체간 협력 게임이론을 적용함으로써 협력관계를 통한 추가이익 발생이 가능하게 되어 강변여과 개발타당성을 확보할 수 있다. 본 연구에서는 입지 선정에서 대상 후보지의 인자비교를 위한 일부 항목의 자료 유무에 상관없이, 적지분석이 가능한 게임모형을 개발하고 그 적용성에 대해 검토하였다.

The economic development and the development of medical treatment by scientific technology development progressed the level of national people life and improved average life gradually. In this reason, old people who have finance power would like to receive a comport and high level service, though paying proper expense. In this study, receiving this requirement, we focused that silver town have reasonable and comfortable residing environment in developing rural and rest form silver town objecting external area of Chon-Ju city, and selected land suitability. Through the learning of the neural network theory in the method of land suitability, we applied in the full of study area and improved a flexible determination making as giving each class value in each cell. Also, we compare a method of land suitability using the neural network theory, and it's analysis with a method of land suitability by the duplication method of Boolean Logic have been used In Geo Spatial Information System(GSIS) and proved the Boolean Logic's lose of values and the propriety.

The management of wastes within the urban landscape has become a critical concern to both local governments and inhabitants. With landfill capacities steadily decreasing, rapid growth of economy, population and urbanization, citizen awareness of the environment and public health problems occured by existing landfill sites make difficulties in selecting the landfill site. Therefore, this study has been performed to select the optimum waste landfill site using GSIS methodology to reduce the time, cost and effort. As the result of this study, we can investigate many factors synthetically which could not be handled by the former method using hands in the site selection for waste landfill, and we can carry out economically the work of selecting suitable site throughout the vast area.
