  • A computer-aided process design system for axisymmetric deep drawing products has been developed. An approach to the system is based on the knowledge based system. The hypothesized process outline of the deep drawing operations is generated in the geometrical design module of the system. In this paper, the module has been expanded. The rules of process design sechems for complex cup drawings are formulated from handbooks, experimental results and empirical knowhow of the field experts. The input to the system is final sheet-metal objects geometry and the output from the system is process sequence with intermediate objects geometries and process parameters, such as drawing load, blank holding force, clearance and cup-drawing coefficient.

  • This study is concerned with exploring how much initial trust transfers between the two websites based on their design levels. Internet users tend to perceive trust towards websites when their design factors look persuasive. For example, well-designed websites can arouse more trust in users than poorly-designed websites. Online trust transfer between websites has been studied among several researchers. However, there is no study investigating how much initial trust transfers from well-designed websites to poorly-designed websites or vice versa. In this sense, this study fills this research void by empirically analyzing initial trust transfer between the two websites based on their design levels. Empirical results prove that design levels of websites affect initial trust transfer between websites significantly.

  • The purpose of this study is to propose a facility layout design algorithm based on artificial intelligence concept, and then to develop a computer program which is more practical than any other conventional facility layout design systems. The algorithm is composed of five step layout procedures; knowledge and data input, knowledge interpretation, priority determination, inference of layout design, and evaluation, In the step of priority determination, the algorithm is divided into single row and multi row layout problem. In the step of inference of layout design, alternatives are generated by constraints-directed reasoning and depth first search method based on artificial intelligence concept. Alternatives are evaluated by the moving cost and relationship value by interactive man-machine interface in the step of evaluation. As a case study, analytical considerations over conventional programs such as CRAFT and CORELAP was investigated and compared with algorithm propsed in this study. The proposed algorithm in this study will give useful practical tool for layout planner. The computer progran was written in C language for IBM PC-AT.

  • The design and manufacture of injection molded Sear with desired Properties is a costly process dominated by empiricism including the interactive modification of prototype toolings. In this paper, an interactive computer-based design system for injection molded gear is developed in order to realize the concept of rational design for the productivity and quality of mold making of a small plastic gear. The knowledge-based synthesis system being developed in this paper combines a rule-based expert system with analytical process simulation programs in a synergistical manner. Quick and logical evaluations on the design of injection molded gear can be made on the scientific analysis and the accumulated experts' knowledge.

  • As the Knowledge Economy grows bigger, studies and practices of knowledge management flourish in almost every organizations. Yet, the studies of fundamental relationships between knowledge and organization have not been sufficiently developed. It is partly because current knowledge management mainly focus on the technical aspects of the theme. This paper tries to find the possible organizing principles and theoretical foundations of knowledge-intensive organizations through the perspective of knowledge market and knowledge community. Based on the differentiation of "knowledge" and "knowing", the author draws several propositions about knowledge creation and knowledge use. Then, the author relates these propositions to the design and implementation of two theoretical models of organizations, i. e. knowledge market and knowledge community. Major claims are: 1) Knowledge use and knowledge creation process are conceptually separable, so that different conceptual models (market & community) need to be applied. 2) Since knowledge use and creation should be integrated, organizations in the Knowledge Economy should be the efficient knowledge market and, at the same time, knowledge community with care and cooperations. 3) The network of independent small KIFs(knowledge-intensive firms) could be considered as the possible organizational model of the future.

  • Recently, the volume of knowledge information in the form of electronic media is quickly increasing in the library field along with the advancement of electronic communication technology. Libraries have both printed data and electronic data and are faced with the issue of corresponding with the access and use of knowledge information in terms of the space. This study is for building the layout of a sustainable knowledge information space based on the view that the library is the official infrastructure of the knowledge information based society. It is intended to analyze the meaning of knowledge information in the modern society, characteristics in the spatial organization and the transmission of knowledge information. The goal of this study is to understand and forecast the spatial structure where users access knowledge information and exchange with one another and developing the direction and guidelines for the spatial plan that today's libraries prefer through this analysis. For this, this study firstly prepared the base for the research on library space which can be considered as the physical realization of such concepts, through the theoretical review about the knowledge information and social concepts as well as characteristics of modern society. Also, it seized the characteristics in the transmission of knowledge information by conducting a structural analysis of the information service such as knowledge information and space, space and information media, space and space through the cases of 10 public libraries. The analysis resulted in basic data including the system of organizing knowledge information, system of knowledge information transferring elements and structure, and layout pattern of each library. These results are deemed meaningful for the promotion of communication with the user through the exchange, creation, and experience of knowledge information, the social role of today's public library.

  • It is an undeniable fact that the modern people's interest in knowledge and information and their roles are some of the core factors used to define the modern society. Besides, as phenomena indicating and leading the modern society, we have fusion, hybrid and convergence, etc. that combine several different elements into a new one. Such changes in social, cultural and technological circumstances require a paradigm shift for the composition of knowledge and information facilities and space. However, more diversified and advanced recently, interfaces for the delivery of knowledge and information cause users to show new behaviors and even change the spatial concept with space composition elements hybridized. Especially for the space of libraries, it is necessary to access and utilize any forms of knowledge and information data (digital + analog) regardless of time and space limitations and approach with an integrated spatial concept likely to change flexibly depending on social demands. In this light, this study aims to make a basic proposal for sustainable integrated-type hybrid space for the space of a public library in this era of knowledge and information. Particularly, this study intends to seek a way to establish a hybrid space model that can effectively converge the most important factors of the space of libraries (human-space(network)-information). With 18 different cases, this study analyzed knowledge and information composition systems, knowledge and information delivery systems and users' space systems. As a result, this study extracted 3 kinds of models, an information-based model, a culture-based model and an education-based model, with the integrated hybrid space model of knowledge and information facilities

  • In this paper, we have constructed an expert system for semiconductor chip encapsulation which combines a knowledge-based system with CAE software. The knowledge-base module includes heuristic and pre-analysis knowledge for evaluation and redesign. Evaluation of the initial design and generation of redesign recommendations can be developed from the rules as applied to a given chip Package. The CAE programs can be used for simulating the filling and packing stage of encapsulation process. The expert system is a new tool which enables package design or process conditions with high yields and high productivity.

  • A study was performed for combination active process between the academical theory and practical design process based on creative thinking process in interior desigv. At first, it was investigated the concepts and characteristics of creativity combined with creativite process of thinking, and also scientific and art characteristics on interior design to be educated together with logical and esthetical concepts required for creative thinking process. In reference with above process, it was systematically established stepwise process of interior design with creative thinking system. As a resualt, creativity in interior design could develop a unique design process combined informations about knowledge and experiences with actual acquirements by individual's experiences. So interior design could be approachable and developed with open-mind and consistently scientific methodology. Also creativity power of interior design could be solved by strategic knowledge acquired by practical experiences and problem solving capability in special branches. Like this, all design activities, including interior design, would be accomplished theoretical background and actual design process under the concepts of practical intension and use. So it would be made creative products by means of detail adapation process based on the theoretical atmosphere, therefore it'll be strongly based on the hardnessing of theoretical value and power. Theory for design process referred to environmental concepts, so including interior design, would not be terminated as for theoretical concepts but be responsible for future of well-developed design by accomplishment of various design adaption method for practical purpose and objectives.
