A Basic Plan for the Promotion of Space Development (hereinafter referred to as "basic plan"), which prescribes mid- and long-term policy objectives and basic direction-setting on space development every five years, is one of the matters to be deliberated by the National Space Committee. Confirmed February 2018 by the Committee, the 3rd Basic Plan has a unique matter, compared to the 2nd Basic Plan. It is to construct "Korean Positioning System(KPS)". Almost every country in the world including Korea has been relying on GPS. On the occasion of the shooting down of a Korean Air flight 007 by Soviet Russia, GPS Standard Positioning Service has been open to the world. Due to technical errors of GPS or conflict of interests between countries in international relations, however, the above Service can be interrupted at any time. Such cessation might bring extensive damage to the social, economic and security domains of every country. This is why some countries has been constructing an independent global or regional satellite navigation system: EU(Galileo), Russia(Glonass), India(NaVic), Japan(QZSS), and China(Beidou). So does South Korea. Once KPS is built, it is expected to make use of the system in various areas such as transportation, aviation, disaster, construction, defense, ocean, distribution, telecommunication, etc. For this, a pan-governmental governance is needed to be established. And this governance must be based on the law. Korea is richly experienced in developing and operating individually satellite itself, but it has little experience in the simultaneous development and operation of the satellites, ground, and users systems, such as KPS. Therefore we need to review overseas cases, in order to minimize trial and error. U.S. GPS is a classic example.

자연하천에서의 흐름특성을 해석하기 위해 Boundary - fitted(BF) coordinate system을 응용하여 유한차분법에 의한 2차원모델을 개발하였다. BF coordinates는 경계면의 형상에 관계없이 적용할 수 있으며 모든 계산은 기본식의 좌표변환을 통해 직각좌표계에서 행해지므로 경계조건의 입력에 용이하다. Physical domain(X - Y 좌표계)에서 하천의 형상을 입력하면 Grid generation에 의해 모든 계산은 Computational domain($\varepsilon$ - n 좌표계)에서 행해진다. Computational domain에서의 유한차분법은 half - time step으로 ADI 방법을 이용했고, 한 방향의 유속과 수위를 Double sweep으로 풀었다. 유속, 수위 및 하상의 격점망은 Staggered grid system을 사용했으며 geometric elements는 각 격점별로 계산하였다. 본 모델을 이용하므로써 불규칙한 수로나 하천의 흐름상태를 해석할 수 있으므로 흐름의 종단, 횡단방향의 유속분포, Superelevation을 구할 수 있고 하천의 계획, 관리, 제방의 호안이나 구조물의 설치등으로 일어나는 수리학적 영향등을 예측할 수 있다.

In Korea, metropolitan cities and provinces are responsible for setting up their own Regional Forest Plans to manage the forests at regional scales distinguished by administrative boundaries, and the role of the plans are very crucial by linking the Forest Basic Plan for nationwide forest management policy with Forest Management Plans for local-level forest management practices. Thus, the analysis of forest resources at regional levels is required to make more efficient regional forest plans by properly reflecting regional forest situations. This study aims to present which species are concentrated at each individual metropolitan city or province, contributing to more efficiently establishing its regional forest plan. In order to measure the concentration levels of species for each region, Location Quotient and Relative-Specialization Index are computed using area- and volume-data for the major species selected in the Statistical Yearbook of Forestry. As a result, the ranks among the indices of the major species for each individual municipal city and province are presented. The results from this study can contribute to the selection of regional target species and establishment of regional forest management objectives. Further study regarding the differences between the results from area-based and volume-based indices will be helpful to consider regional level productivity by species into the regional forest plans.

국토기본법과 국토의 계획 및 이용에 관한 법률은 국토의 지속 가능한 발전을 위한 정책 및 계획을 규정하고 있다. 이를 효율적으로 달성하기 위한 수단으로GIS를 기반으로 공간의사결정 지원체계 구축에 대한 수요가 높아지고 있다. 이는 그 동안 행정업무를 위한 자료관리 중심의 정보화에서 공간자료분석을 기반으로 한 정보화에 대한 새로운 수요라고 할 수도 있다. 그러나 국토공간계획을 지원하기 위한 의사결정지원체계를 성공적으로 구축하기 위해 해결해야 할 많은 과제들이 있다. 본 연구는 국토공간계획을 위한 의사결정지원체계를 구축하는데 장애가 되는 과제를 파악하고, 해결방향을 제시하는데 목적을 두고 있다. 이를 위해 전문가를 대상으로 한 델파이 조사를 실시했다. 본 연구는 공간의사결정지원체계의 설계 및 개발에 영향을 미치는 주요 요인을 중심으로 research questions를 가지고 접근했다. 시스템 설계 관점에서 처리결과에 영향을 미치는 요인으로 입력되는 자료와 지식, 분석처리하는 방법, 인터페이스 등을 중심으로 research question을 설정했다. 시스템 개발과 관련하여 개발도구 확보, 이해관계자 참여 방안, 시스템의 지속성 확보 등을 중심으로 research questions를 설정했다. 마지막은 향후 공간의사결정 지원체계의 연구 및 개발을 효율적으로 수행하기 위한 파트너쉽에 대한 research question이다. 지금까지 국내에서 공간의사결정지원체계 구축과 관련해 기초적인 이론이나 방법론에 대한 연구가 미흡했다. 대부분 외국의 연구 및 개발사례를 소개하는 수준에 불과하다. 특히 공간의사결정지원체계를 구축하거나 운용하는 기반기술인 개발도구에 대한 기술수준이 상당히 미흡하다. 조사결과에서 공개소프트웨어 도입에 대한 필요성 강조가 이를 반증하고 있다. 또한 시민사회의 성숙, 다양한 사회단체 출현 등으로 국토공간계획 과정에 이해관계자 참여정도가 질적 양적으로 높아질 것으로 예상된다. 그러나 이에 대응하기 위한 기술, 기법 등에 대한 연구는 매우 미흡하고 단편적으로 관련 기술을 소개하는 정도이다. 국토공간계획 및 정책과 관련한 다양한 문제해결을 위한 공간의사결정지원체계를 구축하기 위해서 장기간에 걸긴 단계적 접근이 필요하다. 국토공간계획은 우리나라만의 자연 환경 및 인문환경의 특성이 반영되어야 할 것이다. 이를 위해 우리의 개발방법론, 우리의 기술이 개발되어야 하며, 이를 체계적으로 구현할 수 있는 협력체계 구축이 필요하다.

As to the increase of crime against children, the importance of safety in school area is more emphasized ever. Safety in school area can be achieved by the well-organized combination of physical, managemental and spatial planning factors. The purpose of this paper is to investigate the spatial planning direction to prevent crimes for the schools and their surroundings on the viewpoint of CPTED(crime prevention through environmental design). Field survey using checklist drawn up with 5 major CPTED principles was conducted for 7 schools(primary, middle and high schools) located at Noen New-town, Daejeon Korea. Problems derived from field survey were categorized to 5 CPTED principles and countermeasures were suggested together with computer graphic simulation. CPTED design principles and guidelines for spatial planning can make school area safer because these can assure natural surveillance, territoriality, natural access control, etc.

The national land use plan that targets the whole national land and all kinds of urban plans that targets a city or a part of city must be performed continuously now and after that. Therefore, the importance of land use plan, that is included in those plans, is very big and crucial. This study scrutinizes the detail zoning land suitability analysis which bases on urban basis plan and the GSIS application plan about allocation, applied various basic theory which is arranged in that course to study area, and try to develop the land use suitability analysis system, a application system The programing language used in system development is the AML of ARC/INFO. On this study, the results divide into four parts. First, we develop the land use suitability analysis system and can simplify and automatize a complicated analysis course and this system will be more useful to the land use suitability analysis. Second, the analysis range is expanded, considering the circumstance environmental factor of planning area outside. So we can implement more comprehensive analysis. Third, we apply a precedency conception and a legal restrictive element that base on urban characteristics and urban space structure theory to this study, develop a computerized method about distributive method, and can allocate the detail zone in the various ways. Finally, the next studies that can clear the detail zone suitability criteria and the correlation of the relationship of materials are essential to improve the accuracy and confidence in this analysis.
