The Subject of this research is building integrated library to supported to CAAD of the A.E.C field that is oriented to the environment of integrated design. In this research, we design and implement a new library model as a solution of design-data sharing and multi-displaying that is on the rise among many problems in construction integration. We name this integrated library ACO(Actual Component Object) and using the ACO, we can share data without loss in the fields such as construction, estimation, structure. Together with this, the different expressions along each field provide the solution of sharing both graphic data and non-graphic data. This ACO is a newly conceptualized Library that is able to supply a composite structure to an architect(designer) through the internet-based ACO System. To the ACO System that supplies those ACO service, we introduce the concept of DBMS in design and design administrator, and we investigate the solutions that enable an architect to use this ACO directly on the Web.

Ships and off-shore plants have very long lifecycles. Design data of ships and off-shore plants are used as master data in the subsequent phases after the design phase. Therefore, it is an important issue how to convert native design data generated from commercial shipbuilding CAD systems into neutral data with the use of international industrial data standards. International standard-based exchange of ship outfitting and off-shore plant data needs the construction of a library for specifications data of equipment and materials and the provision of external referencing mechanism for retrieving data stored in the library. This paper proposes an approach to construct a specifications data library with the use of ISO 15926 process plants. This library is used for providing specifications data through external referencing when translating ship outfitting data from TRIBON system into ISO 10303 STEP AP 227-formed data.

One of the representative local cultures in Gyeongnam is Gaya culture. This research aim s to develop fashion cultural goods design applying Gaya relics. Based on the study on cu ltural character, formative characteristics of relics, and questionnaire survey on cultural reco gnition and fashion cultural goods purchasing status of Gaya, the plan of Gaya fashion cul tural goods design was made and progressed. To develop design pattern, TexPro Design CAD was used. As to selection of relics to extract motif, Mounted vessel in the shape of warrior on horseback, Chariot wheel-shaped Pottery, Armor and Shield were selected. The main concept of design was 'Timeless Images of Gaya' to re-illuminate a long forgotten p eriod of Gaya, and to create modernization image of ancient period into modern living. By using oring image scale of IRI C or Lab, the 4 main themes of 'Timeless Images of Gaya' including 'Romantic Gaya', 'Dynamic Gaya', 'E -friendly Gaya', 'Modern Gaya' were constructed. According to the 4 themes, basic pattern, repeating pattern, application patter n were developed. And applied cases were developed to seek reality of design in the fashi on cultural goods. Also web page was constructed to develop educational and industrial accessibility and utilization in collaboration with design patterns and fashion cultural goods ap plying cases.

Structure-typed cultural heritage, objects of preservation are positioned as one of the very important heritage in the nation, and the preservation of prototypical structures become influential in national development and against natural disaster. For this reason, Digital Close Range Photogrammetry has recently been diversely used. Despite its popular use, the measurement has limits that make it unsuitable for photographing precise cultural heritage situated at high mountainous terrain or where people can not approach easily. These high gigantic stone statues are among the preserved structure-typed cultural heritage. In order to supplement the limits, when using the measurement, a camera tripod with +30m, a ladder truck and a shore should be equipped, which means additional equipment leads to it being a waste of cost and time. In this vein, a device was developed in detail, using a RC Helicopter installed with a CCD video camera with ease of control, safety, equipment, carrying, movement and approach, then checked image shot by a wireless modem at real time and considered the economical efficiency without re-photographing. Next, the author digitized the images of the nationally designated structure-typed cultural heritage, used materials on their restoration as the third dimension in order to construct the integrated management-information system for cultural heritage. Through the above processes, this study can provide specific information on 3D images and 3D CAD sections of structured-typed cultural heritage for both the public and specialists on the web. Moreover, it suggests the foundation to restore the damaged cultural heritage in the future by aiming for their effective management and preservation.

An information sharing system, namely World Design View, is developed for browsing product design data on the World Wide Web environment. For the last few years information sharing has been rapidly emerging as an important research issue in the areas of concurrent engineering, product data management, virtual manufacturing, and so on. Since we are mainly concerned with product development, the key information that needs be communicated and shared is product data. The developed system puts the major advantages of STEP, OODB, and VRML together. The STEP standard provides a consistent data exchange format and application interfaces among different CAD/CAM systems. OODB is efficient and effective in dealing with complex data structures often found in engineering applications. Virtual worlds for 3-D product models can be created by VRML which is networked via the global Internet and hyperlinked with WWW. The World Design View system can support for members of virtual design teams, possibly distributed all over the world, to share 3-D shape information quickly and easily.

In this paper, a prototype of agent-based engineering system is developed based on the AADE (autonomous agent development environment), a FIPA compliant agent platform. By applying several advanced technologies including software agents, Internet/Web, workflow and database, the developed prototype system is able to successfully fulfill our target of integrating personnel, design activities and engineering resources along a predefined engineering design project (workflow). A software prototype is implemented to integrate various engineering software tools including CAD, structural analysis (FEA), dynamic analysis, fatigue analysis. A wheel-axle-assembly (part of a bogie system) is chosen as a test case for the validation of the prototype system.

본 논문은 웹을 이용한 교량의 실시간 안전감시 시스템을 개발하였다. 시스템이 설치될 교량들은 열악한 환경에 놓일 수 있기 때문에 CDMA 모뎀을 이용하여 실시간 데이터 수집이 가능하도록 하였다. 또한 언제든지 시스템에 접근하여 손쉽게 관리할 수 있도록 웹을 기반으로 개발하였으며, 다양한 교량의 안전감시 센서정보를 하위(low) 레벨의 설정까지 가능하도록 설계하였다. 교량에서 수집된 데이터는 CDMA 모뎀을 통하여 원격 서버에 저장되며, 저장된 데이터는 가공되어 교량의 상태와 위험도를 실시간으로 웹브라우저 상에서 모니터링이 가능하고, 교량의 피로도, 노후화 및 건전도를 측정할 수 있다. 개발된 시스템은 무영대교에 설치되었으며, 시스템의 효율성을 입증하였다.

This research presents a study for the knowledge-based configuration design development of a RC (remote control) helicopter. Parametric design and knowledge based design concepts are introduced for rapid design changes and analyses using commercial CAD software, CATIA(R) Knowledgeware module. It is crucial for RC helicopter design because it enables rapid conceptual design through instant configuration changes. Positions and dimensions of RC helicopter parts were used as design parameters. As an example, positions of CG(center of gravity) points were traced and plotted as the configuration changes. Further research should be performed in areas of user interfaces and web-based multi-user environments instead of using Excel data sheets.

This research explains visualization of diagnostic system of 3D CAD data, IGES (Initial Graphics Exchange Specification), by using JNI(Java Native Interface) to connect between C++ and Java programming. The diagnostic system is to analyze IGES clearly by identifying errors and anomalies with respect to the diagnosis of geometry and topology of entities. The output of the system is IGES file including . error information which can be visualized with different colors by several commercial visualization systems. The paper focuses on the visualization of the result IGES which can be extended to web based application over internet.
