In order to prevent indiscreet urban growth and harmonize urban development with environmental preservation, it is strongly required in Korea that urban planning should be reasonable and transparent. From this societal demand, the urban planning system was changed to be strengthened for the establishment of harmonious land-use order in urban space. However, implementation of the urban planning system demands a lot of information to analyze and estimate the present condition and problems of urban area. For this purpose, the information should quickly be collected, managed and analyzed. The urgent demand of information in urban planning field is able to be fulfilled with recent GIS and its relevant information technique, which can quickly, accurately and conveniently collect various spatial and statistical information, systematically analyze and manage them, and visually present the result of spatial analysis. This study suggested a urban planning information system and its basic implementing scheme to support the urban planning system with GIS and presented a development model of the urban planning information system using the recent GIS and its relevant information technique.

In this study, the concept of spatial big data and effective ways to build a spatial big data system are presented. Big Data is defined as 3V(volume, variety, velocity). Spatial big data is the basis for evolution from 3V's big data to 6V's big data(volume, variety, velocity, value, veracity, visualization). In order to build an effective spatial big data, spatial big data system building should be promoted. In addition, spatial big data system should be performed a national spatial information base, convergence platform, service providers, and providers as a factor of production. The spatial big data system is made up of infrastructure(hardware), technology (software), spatial big data(data), human resources, law etc. The goals for the spatial big data system build are spatial-based policy support, spatial big data platform based industries enable, spatial big data fusion-based composition, spatial active in social issues. Strategies for achieving the objectives are build the government-wide cooperation, new industry creation and activation, and spatial big data platform built, technologies competitiveness of spatial big data.

The study on the updating of the database of Geo-Spatial Information System that is necessary condition to GSIS operation have executed actively. In this study, digital orthophotos were produced by using the product of digital photogrammetry process and then multiscale digital orthophoto maps were generated tv the concept of image pyramids. The produced digital orthophoto has 2.092 meters accuracy compared to 1:5,000 topographic map. This digital orthophoto can be implemented in various Geo-Spatial Information System, providing valuable spatial reference for other objects in the database.

The purpose of this study is to suggest the way of effective use of spatial data in Busan metropolitan city. To do so, information systems and spatial data established in each department are analyzed. Spatial data distribution networks scattered around the nation are integrated to the national spatial information clearinghouse and the service is expanded for the public and the private sectors to participate. Information systems supplied by the central government are 22 and information systems operating in the Busan Metropolitan City are 168. In addition, there are also 295 types of the thematic maps in 11 fields related to the environment, road transportation, livestock, and etc. For systems integration and management system, an integrated information management and linkage system is required in the near future. In the next logical step, generation of metadata, experiments for effective utilization of spatial data, and construction of the data center should be necessary.

사회의 빠른 변화 속에서 지자체가 처리해야 할 정보의 양과 행정수요는 점점 증가하고 있으며, 의사결정과 기획을 위한 정보망과 정보시스템의 활용 계획을 수립하여야 하는 필요성은 더욱 증대되고 있다. 도시정보체계(UIS)의 구축은 의사결정의 효율적인 도구로 각광받아 대다수 지자체에서 활발히 진행되고 있다. 그러나 지자체 행정업무의 70～80%가 공간정보와 연계되어 있다는 막연한 기대감에서 출발한 현재의 도시정보체계(UIS) 구축사업은 단지공간정보 관리 중심의 시스템 개발에 치우치게 되었으며, 시설물 관리 분야에 대한 사업을 이미 수행한 지자체에서는 향후 어떠한 사업들을 전개해야 할 지에 대한 보다 다양하고 구체적인 비전을 가지지 못하고 있는 것이 우리의 현실이 아닌가라는 우려를 하게 되었다. 따라서 본 연구에서는 도시정보체계(UIS)의 새로운 비전 수립을 위해서는 막연하게 제시되고 있는 공간정보 관련성 분석을 보다 세분화하여 수행할 수 있는 공간정보 관련성 분석 모형을 제시함으로써 지자체 도시정보체계(UIS) 구축사업의 현재를 돌아보고 보다 발전적인 새로운 사업추진의 시각을 고찰해보고자 한다. 본 연구에서는 지자체 업무영역에 대한 보다 세분화된 공간정보의 관련성 분석을 위해 공간정보를 업무관점, 업무-정보산출물 관점, 데이터구축관점, 정보관점, 서비스관점으로 세분화여 하여 접근하였으며, 이를 종합하여 최종적인 공간정보 관련성 분석 모형을 구성하였다. 또한 지속적인 도시정보체계(UIS) 사업의 추진을 위해 시간적 개념의 변화 양상을 제시함으로써 GIS의 발달단계에 따라 어떠한 부분에 비중을 둔 사업의 추진이 이루어져야 하는지에 대해서 제시하고자 하였다. 본 연구를 통해 시설물 관리 중심의 도시기반정보화에 편중된 도시정보체계의 구축사업의 시각이 행정정보화, 생활정보화, 산업정보화 등 다양한 분야와 결합하여 보다 큰 시너지 효과와 사용자 중심의 서비스 개선을 창출할 수 있는 기반을 제공할 것을 기대해 본다.. 이상의 결과를 종합해볼 때, ${\beta}$-glucan은 고용량일 때 직접적으로 또는 $IFN-{\gamma}$ 존재시에는 저용량에서도 복강 큰 포식세로를 활성화시킬 뿐 아니라, 탐식효율도 높임으로써 면역기능을 증진 시키는 것으로 나타났고, 그 효과는 crude ${\beta}$-glucan의 추출조건에 따라 달라지는 것을 알 수 있었다.eveloped.

The constitutive model relating the surface force and the deformation of bundle was introduced by considering a representative prodedure that stands for the bundle movement. Then a fundamental equations system could be simplified considering a steady state of the process. On the basis of the simplified model, the simulation was performed and the results could be confirmed by the experiments under various conditions.뢰, 결속 등 다차원의 개념에 대한 심도 깊은 연구와 최근 제기되고 있는 이론의 확대도 필요하다. 마지막으로 신뢰와 결속에 영향을 미치는 요소간의 개념적 분류, 차이의 검증, 영향력 등

In this study, we have acquired the related data of the important culture assets in this country by using close range photogrammetry and GSIS. Also, we have generated database of curtural assets and we have been developing culture assets information system to manage the data effectively. As result of this study, we could facilely operate this system by converting dulistic management to unitary. Therefore, we will act of a part of rearing for effect of many important cultural properties and the domestic information industry from this study.

The absence of present accurate geospatial information can cause us to undergo severe problems in controlling the complicate and multiplicate disaster. Our country is trying to build the Disaster Spatial Data Infrastructure (DSDI), and the key information is the national framework data. This study aims to investigate the characteristics of disaster spatial data, and analyze the present conditions and problems of national framework data, and suggest the way to improve for the GIS application system. In order to provide a wide range of services through the national geospatial data integration system, the data management authority should be established to maintain the consistency of quality and data accuracy of the entire national spatial data infrastructure. In addition, the step-by-step update plan of the national geospatial data should be determined by means of the framework data. And the basic data (lowest common denominator) should be formulated to maintain the data consistency of national spatial information infrastructure.
