  • 토양의 특성은 토지이용에 제한을 가하는 물리적 요소로 활용되고 있으며, 이러한 토양 특성정보는 전통적으로 전문가에 의한 해석에 기초하여 토양도에 서류 형태로 저장, 보관되어 왔 다. 최근에 널리 쓰이기 시작하는 토지정보체계(Geographical Information System, GIS)는 종래의 자료저장, 해석기법을 digital database라는 특성을 이용하여, 새로운 자료분석이 가능한 도구를 제공하게 되었다. 본 연구에서는 위상적으로 체계화된(topologically structured) vector형 토지정 보체계의 관계형 Database Management System(DBMS)과 토양 전문가의 지식을 결합하여 포괄 적인 토양적지 평가모델을 수립한 후, 전문가에 의한 평가, 토양도에 수록된 평가와 각각 비교하 였다. 비교한 결과, 본 연구에서 수립된 토양적지 평가모델은 전문가에 의한 평가와 크게 다르지 않았으며, 이는 토양도의 평가와 비교하여서도 마찬가지였다. 따라서, 본 연구에서 시도된 포괄적 인 토양적지 분석모델은 계속 발전하여 토지정보체계에서의 전문가 기법으로 활용이 가능하다고 판단되어진다.

  • Selecting a suitable place is to determine the attributive conditions and qualified areas for the aim as factors and is to be fulfilled systematically for selecting the area which satisfies all these. This research tries to achieve a rational suitability analysis of residential development using the GIS modeling method and the hierarchical analysis process. A spatial and attributive analysis has been systematized for selecting a suitable place for the study and GIS analysis model has been used for the effective conclusion drawing for different levels. As a next step, a quantitative and qualitative evaluation index was created through complex consideration of the criteria and decision factors of the location selection, and weights were added depending on the relative importance of these factors. In particular, 3D terrain model simulation method has been used in order to reflect the aesthetic factors of the scenery which is an element of the subjective evaluation factors and considered qualitative and subjective evaluation factors which were not considered for the existing AHP technique. After the research, a location that satisfies complex requirements was found rapidly and accurately through the GIS model and hierarchical analysis.

  • This study was implemented to select the suitable site for Palustrine Wetland at habitat restoration for Oriental stork, red species and top-level predator in ecosystem. The evaluation items was fitted by review the antecedent studies on the suitable site selection model and evaluation items of wetland. The study sites were setted in $5,884,800m^2$ area including Yesan-gun Dae-ree, in which Oriental stork' park will be located, through DEM(Digital Elevation Model) watershed analysis. The thematic map by valuation items with secure of water resource, soil, topography, distance between roads, houses, etc., land using, wildlife corridor, and type of water resource was prepared using GIS program. The sites with high evaluation score were selected as suitable creation sites for wetland through overlapping those maps. Total 8 sites with over 18 point were selected. The characteristics of selected sites show that the soil are consisted of clay, the connectivity is valued high with surface water, the slope are gentle, and the connectivity is good with surroundings ecosystem. The result of water quality analysis, which was implement to survey available water resources and develop the solution of problem of water environment, showed that water quality at Salmok reservoir and Bogang reservoir is generally good, but the water quality at stagnant water body rising out from groundwater is not good. This study has limit to select the suitable sites of wetland only by analyzing physiotherapy environment in study area. Hereafter, the study is need to examine closely enhancement effects of biological diversity through investigation of biotic environment.

  • 생산시스템 관련 연구에서 시뮬레이션은 중요한 도구로 폭넓게 활용되어 왔다. 생 산시스템을 분석하기 위한 시뮬레이션 모델은 그 기본구조가 정형화되어 있기 때문에 생산 시스템 시뮬레이터 개발에 관련된 사례연구가 적지 않다. 최근 들어서는 객체지향 접근방법 을 이용한 시뮬레이터가 상용화되는 추세이다. 본 연구에서는 객체지향 생산시스템 시뮬레 이터를 설계 및 구현하는데 있어서 객체지향 접근 방법의 잇점인 재사용성 및 확장성을 제 고 시킬수 있는 방안으로 Pattern을 이용한 설계기법 및 S/W Metrics를 이용한 설계평가 방법에 대해서 논의한다. 또한 현재 개발중인 생산 시스템 시뮬레이터 KU-FASIM에 이런 개념들이 실제 적용된 결과에 대해서 검토해 본다.

  • 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.

  • Local drought in South Korea has recently increased interest in the efficient use of groundwater and then induces a growing need to introduce artificial recharge of groundwater that stores water in sedimentary layer. In order to evaluate the potential artificial recharge sites in the alluvial basins in Chungcheongnamdo province, an AHP (Analytical hierarchy process) model consisting of three primary and seven secondary factors was developed in this study. In the AHP model, adding candidate sites changes final evaluation score through a mathematical calculation process. By contrast ANN (Artificial neural network) model always provides an unchanged score for each candidate area. Therefore, the score can be used as a selection criterion for artificial recharge sites. It is concluded that the possibility of artificial recharge is relatively low if the score of the ANN model is less than about 1.5. Further studies and field surveys on the other regions in Korea will lead to draw out a more applicable ANN model.
