  • The purpose of this study was to research about Dobby weave design using Computer-Aided Weaving System. For performing this design study, first, it was researched the characteristics of the classified woven fabrics, weaving processing, structure of Dobby loom, and Computer-Aided Dobby Weaving system theoretically. To develop Dobby woven design, Patternland Weave Simulator(U.S.A) for computer weave system was used. Among the developed Dobby woven designs by computer weaving system, mainly three of them were selected and woven into Dobby loom. To see the visual image of the fabric end-use, some of the scanned Dobby fabrics were simulated to the three-dimensional virtual images by Alias CAD system. The result of this study can be summarized as follows. Before the step of weaving Dobby fabrics on the woven design works, Computer-Aided Weaving system can be done very easily to apply the design step of Dobby woven fabrics, specially in case of the complicated woven structure. Also the usage of the simulation CAD system in visual image of the final products, ultimately can be saved cost and developed the higher value-added goods in more response to consumer demands.

  • It is the most important technological progress for the computer graphics when computer has incorporated the color system. However, color system used in computer is totally different from traditional color system like printing ink or painting color because it is exist only in the form of wavelengths of light on the computer screen. Therefore, some compatible problems are still remains with traditional design process or color matching in photography. It is important to produce precise representation and management of color in the current design system which is controlled and managed by computer to merge design process. In this study, I have discussed the merits of color, technological characteristics, designer's approach to color and traditional color system. Also I analyzed the aesthetic characteristics of computer color system which are found in computer graphics technology and compared them to traditional color system to try to find some opportunity and possibility for new method of development.

  • For successful implementation of robotic painting system, a structured design and analysis procedure is necessary. In designing robotic system, both functional and economical feasibility should be investigated. As the robotization is complicated task involving implemen- tation details (such as robot selection, accessory design, and spatial layout) together with operation details, the computer aided design and analysis method should be sought. However, conventional robotic design systems and off-line programming systems cannot accommodate these inquiries in a unified fashion. In this research, we develop an interactive design support system for robotization of a cycle painting line. With the developed system called SPRPL (Simulation Package for Robotic Painting Line) users can design the painting objects (via FRAME module), select robot model (ROBOT), design the part hanger (FEEDER), and arrange the workcell. After motion programming (MOTION), the design is evaluated in terms of: a) workpace analysis, b) coating thickness analysis, and c) cycle time (ANALYSIS).

  • A prototype design process visualization and guidance system, is being developed. Its purpose is to visualize the design process in more intuitive manner so that one can get an insight to the complicated aspects of the design process. By providing a tangible utility to the design process performed by the expert designers or guided by the system, novice designers will be greatly helped to learn how to approach a certain class of design. Not only as an analysis tool to represent the characteristics of the design process, the system will be useful also for learning design process. A design ontology is being developed to provide the system with a knowledge-base, representing designer's activities associated with various design information during the conceptual design process, and then to be utilized for a computer environment for design analysis and guidance. To develop the design ontology, a conceptual framework of design activity model is proposed, and then the model has been tested and elaborated through investigating the nature of the early conceptual design. A design process representation model is conceptualized based on the ontology, and reflected into the development of the system. This paper presents the development process of the visualization system, modeling of design process ontology, and how the system could be utilized for the analysis and learning of conceptual design methods using computer mediated design support environment.

  • What's the direction of INTERIOR ARCHITECTURAL DESIGN in 21 Century High Tech\ulcorner The purpose of this research is to show not only practical use of Computer Graphic(CG) as simple tool function, but offering conversation with computer and other ways of method. When we consider poor CG market, investment on the research of VR(Virtual Reality) is the most urgent. The investment on VR will solve various problems. Firstly. It will solve the problems drived from Interior design process by making spatial images like reality. Secondly, It will solve high wages and financial difficulties caused by raise cost funds. Thirdly, It prevents in a road from foreign company that will bring enormous program, caused by opening the domestic market. Also, It help interior designer check in advance the problems in constructure through showing him a supposed imagination including the system and location of equipments. But it is reality that even ordinary American can't offer VR(Virtual Reality) System. We should have noted that it is normal to spend 10 billion won for such presentation as Model House in the large corporation. We must acknowledge that it is such a waist of money nationally. Therefore, investment on CG & VR System is essential in order to save cost more effective presentation & interior design. We will see great result within a year. As we can see, there is huge area we have make develop. One of them is specific technical plan on VR System and study of flow chart. We close with simple methodological way to use VR System and will study Computer System. Which is fitting to CG that we have to solve the link of hardware and software on VR System\ulcorner We know from the cases in other countries that continuous research on this subject has great value for Interior Architectural Design and its effective use. When we try hard not only for methodological use but practical use, the purpose of CG and VR System will be a factor to contribute on this subject for better Interior design & presentation.

  • This paper deals with the personal computer based design for the sequential machines. Most part of sequential machine design have been implemented by using general purpose microprocessors in order to obtain the specific unctions required for their system. But, they have some difficulties in design stages. Knowledge of systems design method and high technology are basically applied to all the design stages.. Therefore ready made microcomputer system for personal use, personal computer, can be transformed to sequential machines by using the corresponding softwares and built-in personal computer input/output ports. Following the state transition diagram or table, we can obtain the ROM type of sequential machines directly and need not to design input/output interface except actuators and samplers because of capability of personal computer. Our main purpose of this design method are quick, flexible, reliable, modifiable circuit design of the sequential machines. In this paper, we use APPLE-II plus personal computer as target machine.
