In the assembly system, a pallet plays an important role of transfer and storage. As products become various, many different pallets are also necessary. Since some of them are redundant, a design of pallet with high flexibility is important. This paper suggests design alternatives, in designing pallets with high flexibility. The purpose of this study is to rationalize assembly process of mid-small size products. Every pallet has suitability values depending on characteristic factors of a product, and this value is determined by using AHP (Analytic Hierarchy Process) technique. As the characteristic factors of a product are changed, the suitability value is also changed. Design alternatives can be found by tracing change of the suitability value, which are based on correlation between the characteristic factors of a product and a pallet element.

The purpose of this study was to carry out land use suitability analysis of Seoul Metropolitan City based on ecopolis planning concept or environmentally sound and sustainable development. Objectives of the analyses were to save energy by increasing urban density and allocating urban land use types near to public transportation system, to increase food producing capacity by restoring fertile agricultural lands, and to enhance urban ecosystem by expanding and networking parks and green spaces. This study has two phases. First, the land use suitability analyses for commercial, industrial, residential, agricultural, and green spaces were carried out. Second, required urban land use .types were allocated based on ESSD concept. Two alternative land use plans were developed based on two population sizes:existing population of 11million and 4.4million derived by the application of ermergy theory of T. Odum.

Environmental Impact Assessment(EIA) in Korea has developed as a tool for environmental conservation and decision making since Environmental Impact Statement(EIS) preparation in 1981. For effective implementation of it, we do system development and method enhancement continuously. The recently introduced GIS (Geographic Information System) can integrate geographic and attribute data, which will be applied to scoping, assessment, and alternative assessment, etc. in EIA. This study has three major components. First, it explains building of EIA factors of natural environment, living environment, and socio-economic environment of the study area defined in EIS preparation regulation. Second, the study presents applications of assessment method concerning suitability analysis of landfill site using GIS. Finally, it shows integration of GIS and odor impact assessment. Based on these analysis, the study makes some recommendations and conclusions.

The objectives of this study are to build up the concept of Environment-Oriented Land Suitability Assessment(EOLSA) and to develop the EOLSA mapping system by applying the EOLSA criteria to the case study area. In order to draw out the EOLSA critera, this study adopted the Delphi method including the experts' awareness survey to urban planners as well as environmental researchers in May and June 2001. As a result, the concept of EPLSA was defined as a process of land use planning to scientifically assess the physical and environmental value of land and to classify conservation aptitude into several grades for the sustainable management of environmental resources. With an outcome of applying the EOLSA criteria with five degrees to the Seoul Metropolitan Area (SMA), Grade I, indicating the highest conservation value, accounted for 57.76% of the SMA. Then, Grade II reached up to 15.06%, Grade III 3.12%, Grade IV 15.92%, and Grade V, the lowest conservation value, 7.99% respectively. And also, the case analysis showed that the share of Grade I area was the highest in Gapyong county and Yangpyong county, Pochon county, Yeonchon county, Yongin city in the order and the lowest in Kwangmyong city, Osan city, Kunpo city, Kuri city, and Buchon city.

A method of improving the correctness and confidence in land use classification as well as urban spatial structure analysis of local governments using GIS and satellite imagery is suggested. This study also compares and analyzes LSAS (Land Suitability Assessment System) results using two approaches-LSAS with priority classification, and LSAS using standard estimation factors without priority classification. The conclusions that can be drawn from this study are as follows. First, a method of maintaining up-to-date local government data by updating the LSAS database using high-resolution satellite imagery is suggested. Second, to formulate a scientific and reasonable land use plan from the viewpoint of territory development and urban management, a method of simultaneously processing the two described approaches is suggested. Finally, LSAS was constructed by using varieties of land information such as the cadastral map, the digital topographic map, varieties of thematic maps, and official land price data, and expects to utilize urban management plan establishment widely and effectively through regular data updating and problem resolution of data accuracy.

PURPOSES : While road networks are becoming increasingly complex, traffic signs are being indiscriminately installed and operated, which makes drivers who depend on traffic signs to reach their destination confused and unable to understand road information efficiently. In order to promptly and exactly guide road users to their destinations, traffic signs should be able to satisfy the functions of connectivity, visibility, and location suitability. However, the results of a site survey shows that most of the traffic signs currently installed in the Jeollanam-do Province do not satisfy these functions. METHODS : This study analyzed the problems of traffic signs after an actual site survey and focused on a total on 9,353 traffic signs and 70 road routes in Jeollanam-do Province. RESULTS : This study analyzed the problems of traffic signs based on their required functions (connectivity, visibility, suitability) and suggested improvements by establishing a guide system that considered the problems found in the study. CONCLUSIONS : The guide system can be utilized as a basic material that provides efficient road information for future installation and maintenance of traffic signs in Jeollanam-do Province.

토지의 개발 또는 보전을 결정하는 적성은 토지가 가진 물리적 특성, 그 토지가 속해있는 주변지역의 특성. 토지의 공간 입지적 특성, 생태환경적 특성 등에 의해 결정된다. 이 논문에서는 전문가조사법과 AHP법을 활용하여 토지의 적성을 결정하는 지표를 분석하고 각 지표가 토지의 적성을 결정하는데 미치는 영향력을 분석하였다. 그 결과 토지의 적성을 결정하는 지표는 개발적성 또는 보전적성별로 각기 다른 지표들이 분석되었고 지표별 영향력도 각기 다르게 나타나는 것으로 분석되었다. 개발적성을 결정하는 지표는 경사도, 표고, 인근용도간 부합성, 용도전용비율, 기개발지거리, 공공편익시설거리의 6개 지표로 분석되었고, 이 중에서 기개발지거리 지표와 공공편익시설거리지표의 영향력이 높은 것으로 분석되었다. 한편 농업성을 결정하는 지표는 물리적 조건 상 경사도가 높지 않은 지역이면서 제도적으로 농지를 보전하기 위해 지정한 농업진흥지역의 비율이 높은 지역이나 농업적 투자를 한 지역(경지정리지역) 또는 그들 지역과 근접해있는 지역인 것으로 분석되었다. 한편 보전지역은 생태자연도상의 상위등급지표가 가장 중요한 것으로 분석되었고 그 다음이 각종 법에서 보전지역으로 지정한 면적비율인 것으로 나타났다. 이러한 지표별 영향력을 반영하여 적성평가를 실시해본 결과 적성을 판단하기 어려운 중간 적성값의 필지보다 개발적성과 보전적성이 강조된 양극단의 적성값을 가진 필지비율이 증가하는 것으로 분석되었다.

본 연구는 도시계획의 중요한 의사결정 중의 하나로서 토지이용계획을 위한 적지분석에 지리정보시스템의 접목을 시도한 것이다. 도 농 통합 이전의 구미시 지역을 대상지역으로 하여 관련 환경인자들과 가중치 등의 분석기준을 결정하고, GIS 데이터베이스를 구축하였다. 또한 위성영상처리를 통하여 추출한 토지이용/피복도와 NDVI 식생도를 데이터베이스에 포함시켰다. 중첩법을 이용하여 주거, 상업, 공업, 녹지지역의 토지용도별 적지를 등급별로 도출하였다. 연구지역의 4가지 기능공간에 대한 적지분석 결과는 기존 토지이용 및 도시기본계획상 토지이용구상도와 비교되었다. 더 나은 분석을 위해서는 실제적인 개발계획, 지가자료, 토양자료 등이 포함되어야 하며, 토지 이용별 수요추정 자료를 추가한다면 토지이용별 입지 배분 및 분포면적의 신뢰도를 더 높일 수 있을 것이다.
