It is impossible to do real verification on design spaces before their completions due to the characteristics of building and interior space designs. So, in designing spaces, designers should reflect their real experiences in their lives into their design works. 3D games where GPU and other kinds of advanced technologies have bee applied first show their leads in technologies have bee applied first show their leads in technologies about 5 years than VRML. Those games which are produced reflecting real environment as it is could be regarded as the most excellent tool in their completeness level of physical environment due to their characteristics. This means that if 3D game engines employing GPU are used effectively they could be used as a presentation tool for virtual spaces. This study studies the expressions of virtual constructions through 3D game engines employing GPU, not in VRML-based virtual spaces on Webs but in immersion-type virtual spaces.

현대사회는 정보화 사회로 모든 사람들이 빠르고 정확한 정보를 필요로 하고 있으며 이러한 정보를 신속히 받아들여 생활에 활용하기를 원한다. 또한 현실의 한정된 공간과 시간에 구애받지 않고 보다 자유로이 상상의 세계를 현실과 같이 경험하고자 한다. 디자인은 '무'에서 '유'를 만들어내는 창조적인 행위로써 '가상'(Virtual)적인 의미를 내포하고 있다. 따라서 디자인은 상상 속에 존재하는 형태나 이미지를 실제로 재현하기 위한 '가상의 현실화'(Reality of Virtuality)작업이라 말할 수 있다. 디자인 분야는 과거로부터 현재까지 컴퓨터 응용 방법들이 많이 활용되었다. 컴퓨터의 발전과 함께 디자인 과정 또한 시간적으로나 방법적으로 간편화되었고 또한 효율적으로 발전하였는데 이러한 의미에서 컴퓨터는 디자인에 지대한 영향을 미치는 하드웨어임에는 틀림이 없다. 이번 연구는 환경디자인(Environmental Design)에 적용되고 있는 컴퓨터 활용 방법에 대해 알아보고 단순한 활용에서 적극적이고 체계적인 방법으로의 모색을 통해 현실감(Presence)을 극대화하여 이를 설계에 적극적으로 도입하는 방안에 대하여 연구하고자 한다. 현재 연구가 활발히 진행되고 있는 가상현실 시스템(Virtual Reality System)을 환경디자인(Environmental Design)분야에 폭 넓게 활용하여 수준 높은 설계를 제공하고 모의실험을 통한 현실감의 극대화를 도출하고자 하며 앞으로 가상현실 시스템(Virtual Reality System)과 같은 다양한 컴퓨터 시뮬레이션 기법들이 환경디자인에 적극적으로 도입될 전망이다.

First we provide an overview of how virtual enterprise works, including the lifecycle of a virtual enterprise, expected benefits from a virtual enterprise, and various types of collaborative networks. Next we focus on a problem encountered in the port logistics industry and suggest that implementation of a virtual enterprise can be a good solution to the problem. Then we suggest a prototype of the virtual enterprise in the port logistics industry and a freight transportation process as a business process in the prototype. And then we introduce major functions of the business process management system (BPMS) which, in general, can be regarded as a tool to create the virtual enterprise. Finally by adopting a specific BPMS, we illustrate how to design and implement the freight transportation process in the prototype.

This paper is to develop an information infrastructure to support managing process in design, planning, production, and quality control. Multi-media data set of design, product, and management information flow between organizational units of a virtual enterprise. The process is the logical organization of people, technology and practices incorporated into work activities to make an end product. The core of the infrastructure is the enterprise framework which coordinates activities and controls the process. The proposed framework manages collaborative activities across space and time, and between users and computers who share information in virtual community. It utilizes knowledge distributed through virtual community and fosters cooperation between organizations. The framework provides the following facilities； coordinating activities, sharing data and processes, visualizing multi-media data, customizing and updating processes, reusing data and processes. This paper covers design and manufacturing activities but our focus is initially targeted at design area.

De-manufacturing is an entire process of collecting, disassembling, reusing, refurbishing, recycling, and/or disposing products that are obsolete or un-repairable. Designing the products for inexpensive and efficient disassembly enhances the ease of de-manufacturing. Virtual disassembly addresses the difficulty and the methods to disassemble a product in design stage rather than really disassemble a product at the end of its life cycle. Based on the virtual disassembly analysis results, design will be improved for better assembling/disassembling. This paper presents a systematic virtual disassembly methodology such as disassembly relation modeling, path/sequence automatic generation and evaluation. This paper also presents a new virtual disassembly interface paradigm via virtual reality technology for disassembly simulation in virtual environment.

When the design modification is occurred, at present, design process based on 2-D spend more time and effort than that based on 3-D to modify related structural details. To improve and develop these processes, therefore, the design possibility of civil structures based on virtual model of 3-D must be investigated. We designed reinforced concrete pier of 3-D model, containing parameters. The parameters was defined as structural details like area of the section, reinforcement specification for design modification and structural analysis. In this paper, we researched about the processes modeling of reinforced concrete bridge pier based on parameters, the extracting data from the virtual model of 3-D, and the reflection of data to virtual model throughout structural analysis.

The purpose of this study was to investigate how student felt the strengths and shortness of presentation methods for formation of interior spaces. For this study, the process of the interior architecture design class was divided into three stages: the programming. the design development, and the design completion. In the design development stage, students used presentation methods: hand sketch, scale model, computer modeling, and virtual realty. The strengths of hand sketch was that quick expression. Models provided three-dimensional feelings. Computer modelling provide realistic color and texture. Virtual reality provided three-dimensional immersion and real scale. It is effective that students collect brain storm images using quick hand sketch in the beginning of design development stage. After that, they compose interior spaces in study models with small scale. Watching the models, they design details of spaces by using hand sketch and computer modelling. Using virtual reality, they can check the scale and circulation. Finally, they complete computer modelling by texture mapping and check the final design in virtual reality.

Context-aware engineering services in ubiquitous environments are emerging as a viable alternative to traditional engineering services. Most of the previous approaches are computer-centered rather than human-centered. In this paper, we present a Ubiquitous and Context-Aware computing Framework for collaborative virtual Engineering $(U-CAF\acute{E})$ services. The proposed approach utilizes BPEL-based (Business Process Execution Language) process templates for engineering service orchestration and choreography and adopts semantic web-based context-awareness for providing human-centered engineering services. The paper discusses how to utilize engineering contexts and share this knowledge in support of collaborative virtual engineering services and service interfaces. The paper also discusses how Web services and JINI (Java Intelligent Network Infrastructure) services are utilized to support engineering service federations and seamless Interactions among persons, devices, and various kinds of engineering services.
