The Semantic Web introduces the next generation of the Web by establishing a semantic layer of machine-understandable data to enable machines (i.e intelligent agents) retrieve more relevant information and execute automated web services using semantic information. Ontology-related technologies are very important to evolve the World Wide Web of today into the Semantic Web in representation and share of semantic data. In this paper, we proposed and implemented the efficient ontology management system, K-Box, which constructs and manages ontologies using topic maps. We can use K-Box system to construct, store and retrieve ontologies. K-Box system has several components: Topicmap Factory, Topicmap Provider, Topicmap Query Processor, Topicmap Object Wrapper, Topicmap Cache Manager, Topicmap Storage Wrapper.

This study aims to development of web-based process management system for spatial data construction. For developing this system work classification of basic surveying was standardized and quality management method for spatial data was established. Production process and work classification system for basic surveying such as control point surveying using GPS, leveling, aerial photographing, digital mapping, topographic mapping, digital elevation modeling, aerial photographic DB construction and digital orthophotomap was standardized. The status of the output and quality inspection for basic surveying project were analyzed, and the elements of quality inspection and data format for the type of outputs were analyzed. Based on standardized and analyzed contents, web-based process management system was developed after database and process was designed. The process management system consisted of process management, quality control, metadata management, and system management.

기존 제조업체는 저렴한 운용비용과 관리가 용이하기 때문에 기업 내부에서 안 사용하는 인트라넷 생산관리 시스템을 사용하고 있으나 외부업체와의 업무연결, 외부사용자와의 상호소통이 힘들다는 등의 문제점을 가지고 있다. 따라서 인트라넷의 확장개념으로 고객 및 협력업체와의 관계 증진을 위해 기업의 내부 통신 시스템인 인트라넷에 이들을 포함시킨 엑스트라넷의 도입이 절실한 실정이다. 이에 본 논문에서는 제조업체의 기존 인트라넷 기반의 생산관리 시스템을 보완하기 위해 외부업체와 제조업체간의 업무를 향상시키는 인터넷을 통한 주문관리가 가능한 Web-Deal 시스템을 개발하였다. 이 시스템은 정보이용자와 정보를 창출하는 업체 사이에 거의 즉각적인 상호작용이 가능하므로 진행 상황을 실시간으로 알 수 있다. 따라서 신속한 업무처리에 의해 고객의견을 즉시 반영할 수 있는 시스템이다.

The slope monitoring systems which have been operating at home and abroad were investigated and then the real-time monitoring management system for evacuating inhabitants based on Web-EOC(Emergency Operating Center) was constructed. We tried to analyze realistically and precisely the situation by changing from the existing field-centered management to sensor-centered management that measures coordinates and provides in real-time data of measuring/monitoring sensors installed at a field site and developing related viewer programs. In addition, the 3D based monitoring management system, which has alarm functions in case of emergency and provides information about the evacuation place, was constructed on the base that is able to expand to nationwide fields by using Vworld 3D map. Ten steep slope monitoring sites were registered on Web-EOC slope monitoring management system constructed in the research and then application instances were suggested.

WebDAV는 HTTPI.1을 확장한 기능으로 지역적으로 분산되어 있는 사용자들 사이에 공동 저작활동을 지원하는 표준 프로토콜이다. WebDAV의 주요 기능인 속성 관리는 저장소의 역할과 함께 자원의 추가 정보를 관리하고 활용할 수 있는 장점을 가지고 있다. 그러므로 WebDAV 기반의 응용 프로그램을 개발하기 위해서는 사용자 정의 속성의 설계 및 속성의 효과적인 관리가 매우 중요한 역할을 한다. 본 논문에서는 헙업을 지원하는 Teamworkspace에 필요한 WebDAV 사용자 정의 속성을 설계하고 설계된 속성을 효과적으로 관리하기 위한 방법을 제안한다. WebDAV를 기반으로 Teamworkspace를 개발함으로써 헙업을 위한 편리한 자원의 관리 및 공유가 가능할 것이다.

To reform and improve the productivity of construction industry, 1) it should be encouraged to improve the construction production process and 2) it is required to enhance reliability of construction information based on the systematic thinking process. To promote the information reliability created during construction production process, Lean Construction Research Center(LRC2) is developing a supporting system to improve design/material supply/schedule management, functioning to efficiently manage the information created at construction production processes and developing a web based construction information system that provides result management/decision making support/knowledge based information services.

Recently, as the development and use of distributed multimedia services are growing explosively in every aspects of our lives, administrators of multimedia services are very concerned with providing users with reliable and efficient services. However, the management of distributed multimedia services is a very complex and troublesome work such that a flexible but powerful management system is necessary. This paper proposes a management system for managing CORBA-based distributed multimedia services. We have developed an architecture for the management system and defined a set of management services needed to monitor and control distributed multimedia services. The architecture consists of several objects, which perform configuration management, fault management, security management and event management. A generic distributed multimedia service (DMS) MIB has been defined for the management of various multimedia services and applications. In addition, as a proof of concept, we have developed a Web-based management system for a CORBA-based distributed multimedia system called MAESTRO. The prototype management system uses OrbixWeb to interface with the management server which is implemented as a set of CORBA objects. Though our management system has been developed for distributed multimedia services, it can easily manage other CORBA-based services and applications.

A web-based information management system to share engineering data of truss bridge is developed through construction of standardized database of truss bridge. 3D shape information is stored in database according to AP 203 of STEP, and 3D visualization on the web is implemented by using the web 3D technology that helps users to understand geometrical shape of structures, directly. AP209 is used to store structural analysis information such as finite elements, material properties, and analysis result into relational database. Based on the developed database, a prototype of integrated information management system for truss bridge is developed, and it provides additional information such as specifications and inspection information related with shape object to end users.
