Collapse of a huge structural material has brought about enormous loss of lives and property. Every construction may be destroyed by the nature's power and careless mistake of human as well as its own defect. So a great number of concern and detailed managing technique are demanded not in constructing work but also in management of constructed material. The Interest of construction safety has Increased rapidly and a plenty of effort has been attempted to manage systematically. In this study, the use of FM(Facilities Management) as a branch of GSIS(Geo-spatial Information System) was developed to offer the users convenient managing achievement and establishment of history managing system in the bridge management system. This study accomplished dividing all information of images, photos, drawing and etc. into their items of time, material and the person in charge, and developed to stue and maintain those items in database. Related database which is composed of recording of check, retrieving and adding the data was accomplished to an easy access of database, and by using these data as output for example images, m display, report and hard copy, this system was proved to help manage efficiently in bridge management system.

This study aims to develop a hydrological information management system to manage the hydrological data of Han river integratedly. Various data related to hydrology such as water level, dams, the positions of the hydrological structures for Han river were collected and inputed to build the hydrological information management system. The Database Management System(DBMS) of Korea Water Resources Cooperation which is operated in the form of digits and characters was linked to the Geo-Spatial Information System to join positional information and digital information and to analyze the hydrological data using graphical techniques. Through this study, the positional errors which occurred when digital or characteristic informations were only used, were detected. And the hydrological information management system was presented to estimate the reliability of data related to water level among the hydrological information and to show the basis of output used to correct the data.

With the new paradigm of ubiquitous in the developed computing technology, it is urgently necessary to research GIS fields centering around positioning techniques. The intention of this study is to propose implementation methods for integrating topographic and cadastral data. For this purpose an integrated data model is formed to coincide the graphic data of cadastral map with that of topographic map. As a result, the integrated data model could be built by harmonizing cadastral map with topographic map. We suggest data model for connecting with other information systems in the conditions of data uniformity and implementation. This data implementation models suggested in this research can provide a good reference for the future implementation of other systems. This results will be efficiently used as basis for practical use in ubiquitous environments of spatial informations.

The purpose of this study was to investigate essential information about the geological and geomorphological characteristics of the Odaesan landscape, in order to efficiently preserve and develop resources selected from among that are highly valuable scholastically and esthetically. A total of 147 geological and geomorphological landscape resources were studied during the course of this study. Landscape type mostly discovered was the tectonic topography, followed by the topographies of weathering, river, mountain, lacustrine, and periglacier, respectively in decreasing order. Among the varieties of geological and geomorphological landscape resources, 4 outcrops were utilized as tourist resources and 5 outcrops were considered as valuable sites for scientific research. Geological and geomorphological landscape resources for academic research were considered to have practical uses such as geological and geomorphological fieldwork for students and thematic geotourism courses for the public.

This study aims to analyze the existing problem of geo-spatial information maintenance and then, show maintenance strategies suitable for new integrated environments. We look for AS-IS which is provider-centered, top-down, and also drive implications from analyzing oversea best practice. For analyzing of geo-spatial maintenance pattern, we polled about 20 local governments and private enterprise to find out AS-IS of geo-spatial information and result in maintenance pattern and component. From this, we suggest 4 kinds of strategies. This study shows the strategy not only which decide the question about the problem of existing geo-spatial maintenance but which find a way of combining and utilizing all geo-spatial information which is 8 criteria basic geographical information. This is a win-win program of all organization which produce, construct, make full use of national geo-spatial information.

In the past, most of battle occurred in flatland and simple military force size gave a big influence in combat result. However, after the World War I, most of battles took place at the various terrain features such as forest, downtown, jungle and many others. Therefore, terrain factor exerts big influence on battle with weapon system in the ground warfare. However, effect of terrain has been explained only by quantitative manner in the battle. Furthermore, combat simulation and modeling applied a method that lower the combat capability of battle factors. In this paper, we present instrumentation that evaluate impact of terrain using fractal dimension. We determine the fractal dimension value by the "box counting dDimension" and density to calculate impact of terrain. Furthermore, we analyzed correlation with fractal dimension and density for battle result that obtained from the EINSTein model which is an agent-based simulation. We compare with 'Stalingrad battle' result out of battle example and analyzed. This study presented a method combat effectiveness that effect of terrain calculate quantitatively using fractal dimension.

과거의 용수개발은 단위시설 또는 단위사업별 중심의 양적 확대개발 위주로 추진하여 수리시설간 수자원을 효율적으로 활용할 수 있는 용수공급체계가 미흡하였다. 수리시설의 양적 확대개발 위주의 추진결과 '03년도 총 수리시설수인 68,018개소 중 관개면적 50ha이상의 주 수원공은 1,888개소로서 전체수리시설의 2.8%를 차지하여 비합리적인 공급불균형 현상이 발생하여 체계적인 급수관리가 이루어지지 못하는 문제가 발생하였다. 또한 기존의 공급체계는 논 용수중심에서 식생활 변화로 인한 밭작물 수요증가로 용수이용 패턴이 변하고 있다. 더욱이 농촌지역의 생활환경 개선이 요구됨에 따라 생활용수, 공업용수, 환경용수 등 농촌지역에 과거와는 다른 형태의 용수수요가 발생하고 있다. 하지만 농촌지역의 수자원은 한정되어 있고 환경파괴 및 적지부족 등의 이유로 신규 수자원개발이 불가능한 사회여건이 지속되어 있어 많은 문제점이 나타나고 있어 균형적인 농촌발전과 건전한 농촌지역조성을 위해서는 새로운 대안이 제시되어야 하는 시점이다. 본 연구에서는 그 대안으로 부각되고 있는 농업용저수지 재개발에 대하여 사업의 우선순위를 합리적으로 결정할 수 있는 의사결정시스템의 개발을 목적으로 하고 있다. 기존 문헌을 고찰하면 개발우선순위는 과학적 논리보다는 정치적, 사회적 논리가 의사결정에 중요한 역할을 하였으나 의사결정시스템의 제공을 통해 정책결정자가 과학적이고 합리적인 논리에 따라 사업개발의 우선순위를 결정할 수 있을 것으로 기대한다. 본 연구에서는 재개발 의사결정에 필요한 지형적, 사회적, 환경적 요인을 지수화 하는 방법을 고찰하였고, 우선순위를 산정에 필요한 수치지도, 저수지 관련 자료의 작성과 지형정보(GIS)를 구축하였다. 우선순위 대상저수지의 선정은 기존문헌과 수계 및 용량 등을 고찰하여 79개로 우선 선별하였다.

Researches on method for quantitative analysis applied with decision-making in consideration of variation in risk factors based on GIS(Geographic Information System) concluded as follows. Firstly, by way of decision-making in consideration of variation in risk factors, quantitative analysis performed for the existing route was applied to the new route, which would bring about reliable criteria in route planning and basic design stage. Secondly, horizontal and vertical alignment were easily available out of GIS for relatively speedy design and analysis with three dimensional alignment by decision-making in route planning. Thirdly, automation of route alignment is possible by utilizing quantitative evaluation system established in this research so that a risk analysis can be carried out in a relatively short time. Therefore it will eventually contribute to further development of road design technology.

국방 시뮬레이션 유형은 워게임 모형으로 분류되는 Constructive 시뮬레이션, 실 기동에 의한 Live 시뮬레이션, 그리고 가상현실을 적용한 Virtual 시뮬레이션 등 3가지로 분류될 수 있다. 워게임 시뮬레이션은 일반적으로 대부대 훈련에 적합하지만 많은 가정사항을 내포하게 됨으로써 현실감이 떨어지고 실 기동 시뮬레이션은 실전적인 훈련이 가능하지만 전구급 수준의 대부대 훈련에의 적용이 곤란한 단점이 있다. 또한 이들 시뮬레이션 유형들은 개별적으로 운용됨으로써 각 유형들이 가지고 있는 취약점이 노출되고 있는 현실이다. STOW(합성전장 훈련체계, Synthetic Theater of War)는 실제훈련이 가능한 분야는 실 기동으로, 실 훈련이 불가능한 전장상황은 시뮬레이션 기법을 활용하여 상호결합 시킴으로써 각 시뮬레이션 유형들의 제한사항을 상호 보완하여 실제와 유사한 전장을 조성하여 훈련하는 종합적이고 체계적인 훈련체계로써 21세기에 예상되는 전쟁이외의 작전(OOTW), 비대칭전, 정밀타격 및 C4I를 모의할 수 있는 엔티티 수준의 합성전장이다. 본 고는 STOW의 구성요소(합성부대, 합성환경, 시뮬레이션 네트워크, 지형 DB 개발도구, C4I 인터페이스, 기반체계 등)를 국내기술 능력과 비교, 분석함으로써 우리의 여건에 적합한 STOW 체계 구축방안을 제시하고자 한다.
