고고학자들은 발굴 후 발굴과정에서 기록된 사진, 그림, 구덩에 대한 데이터를 분석하는 것에 기초하여 연구한다. 각 데이터들은 연구자들의 연구 분야별로 석기, 식생, 지질, 유적지 및 지구 등으로 나뉘어져 있으며 한 유적지의 자료들을 각각 별도의 파일로 저장하고 있다. 따라서 현재 연구자들이 이러한 자료들을 연구에 활용한 수 있는 통합적 환경을 제공하지 못할 뿐만 아니라, 기존의 유적 및 유물들에 대한 체계적인 관리, 자료 상호간의 연관성 문제 등이 대두되고 있다. 따라서 이 논문에서는 중원지역의 구석기 유적지, 유물 및 지질 자료들을 하나의 데이터베이스로 저장하기 위한 모델링을 수행하였다. 이로 인해 기존의 개별적인 자료들을 하나의 자원으로 체계적 관리가 가능할 뿐만 아니라 각 자료들간의 상호 연관성 파악을 위한 기반을 마련한다.

Manufacturing companies should perform process planning and its evaluation concurrently with new product developments so that they can be highly competitive in the modern market. Process planners should make decisions in the manner of concurrent and collaborative engineering in order to reduce the manufacturing preparation time and cost when developing new products. Automated generation of analysis models from the integrated database, which contains process and material information, reduces time to prepare analyses and makes the models reliable. In this research, we developed a web-based system for concurrent and collaborative system for production flow analysis, using web, database, and simulation technology. An integrated database is designed to automatically generate analysis models from process and material plans without reworking the data. This system enables process planners to evaluate their decision fast and share their opinions with others easily. With this system, it is possible to save time and cost for assembly process and material planning, and reliability of process plans can be improved

Earthquake event keeps increasing every year, and the recent cases of earthquake hazards invoke the necessity of seismic study in Korea, as geotechnical earthquake hazards, such as strong ground motion, liquefaction and landslides, are a significant threat to structures in industrial hub areas including coastal facilities. In this study, systemized framework of integrated assessment of earthquake-induced geotechnical hazard was established using advanced geospatial database. And a visible simulation of the framework was specifically conducted at two coastal facility areas in Incheon. First, the geospatial-grid information in the 3D domain were constructed with geostatistical interpolation method composed of multiple geospatial coverage mapping and 3D integration of geo-layer construction considering spatial outliers and geotechnical uncertainty. Second, the behavior of site-specific seismic responses were assessed by incorporating the depth to bedrock, mean shear wave velocity of the upper 30 m, and characteristic site period based on the geospatial-grid. Third, the normalized correlations between rock-outcrop accelerations and the maximum accelerations of each grid were determined considering the site-specific seismic response characteristics. Fourth, the potential damage due to liquefaction was estimated by combining the geospatial-grid and accelerations correlation grid based on the simplified liquefaction potential index evaluation method.

Even though the frequency of constructing spatial structure is increasing currently, the problem is that no efficient medium to provide information of goof quality on spatial structure is existed. The information is available only for some limited number of major construction companies with experiences, not for the academic world, officials. It costs us much time and money gaining the information for spatial structure without integrated media. Thus the purpose of this study is to develop an integrated web database model for spatial structure.

It is necessary to develop the one stop system in order to protect our marine environment rapidly from oil spill accident. The purpose of this study is to develop real time database for oil spill prediction modeling and implement real time prediction modelling with ESI and server-client GIS based user interface. The existing oil spill prediction model cannot provide one stop information system for public and government who should protect sea from oil spill accident. The development of multi user based information system permits integrated handling of real time meteorological data from external ftp. A server-client GIS based model is integrated on the basis of real time database and ESI map to provide the result of the oil spill prediction model. End users can access through the client interface and request analysis such as oil spill prediction and GIS functions on the network as their own purpose.

Product catalog information is the most important factor to make customers purchase the product for various B2B or B2C businesses provided on the Internet. As catalog information differs from company by company, it cannot provide common criteria standard to customers to make decisions. Therefore, it is necessary to develop a platform independent system, which integrates incompatible data from each company' catalogs and manages its database. This paper describes the integrated E-catalog system made up DB module, catalog management module, and interface module. This system allows customers to view standardized product catalog information from different companies with real -time updates, and also provides extensibility, flexibility, and interoperability for the effective E-Business management.

Recently car navigation systems which have been widely spread and evolved. The systems use various information and techniques such as real time traffic information and augmented reality technique. In order to provide a shortest path with good flow, real-time traffic information provided by DMB is required. Augmented reality technique is also introduced to give a reality to driver by displaying real images captured by camera during driving. However, these operate well when the system receives GPS data normally. Exact information about the positions of vehicles is a base that supports the above function with realities. This paper proposes a model for acquiring exact position of vehicles. When the GPS does not operate normally, the proposed model uses various data which are generated by integrated vehicle networks.

This paper concerns developing an integrated online/offline light facility management system using internet and building a database system for control box and street light. Also, we designed the system to minimize the disparity with the conventional management system by referring to an old management ledger format. Thus, the proposed method may enable the system manager to administer the light facility efficiently and to reduce the manpower and maintenance cost, economically.

This paper discusses a set of critical requirements in building and using a shared, integrated information management system for power distribution management and control. It then proposes a modem, object-oriented information system model for building such a system based on the current state of arts in database, GIS, and WWW technologies. The key of the proposal is that the shared database system should be the basis of integration efforts in power distribution management and control. A small-scale prototype is being developed to demonstrate the effectiveness of the proposed model.
