  • This study describes an application of a knowledge-based system for a part of the development of an integrated structural design system. In preliminary structural design procedure, most structural design operation are performed by structural engineer's manual method. These lack of systematic operation hampers the effective system integration. By introducing expert system to the structural planning stage, structural engineer can automate structural Planning process of an integrated structural design system for complex design. Engineering data management is receiving increasing attention due to complexity of information necessary for performing structural engineering operations. So, in this paper, we describe a methodology for automating conceptual structural design and developing a knowledge-based system integrated with database. At the end, we use an implemented example to support our methodology.

  • The purpose of this study was to find the characteristics of the exhibition space planning methodology as 'Spatialization of Knowledge' through analyzation of the spatial structure in the contemporary museum architecture. The result of this study is expected to apply in designing an exhibition space and may become a target point. Further more this study can result a museum design to assist actual museum to fully function and play a role as a service facility for users by containing broad knowledge and fair understanding of user's needs in museum planning. Basic survey of museum architecture history will help visualizing conceptual structure of the museum exhibition and the 'Space Syntax' method has been used to make this conceptual data more objective. This study found that the contemporary museums most likely to include in its planning the various spatial organization in order to convey knowledge. The result reflects the needs of modern society which shows the design accepting individuality in society with variety of needs. And this also explains that museum space organization has to reflect various ways or methods of conveying knowledge. In addition, users have tendency to prefer more open space organization for easy access and approach in exhibition environment. It is clear to see the change in today's viewing pattern that the users prefer flexible exhibition space where they can be more proactive in receiving knowledge by following their own circulation over architecturally constrained circulation pattern within the exhibition area.

  • This paper proposes a qualitative reasoning approach for the spatial configuration of mechanisms that could be applied in the early phase of the conceptual design. The spatial configuration problem addressed in this paper involves the relative direction and position between the input and output motion, and the orientation of the constituent primitive mechanisms of a mechanism. The knowledge of spatial configuration of a primitive mechanism is represented in a matrix form called spatial configuration matrix. This matrix provides a compact and convenient representation scheme for the spatial knowledge, and facilitates the manipulation of the relevant spatial knowledge. Using this spatial knowledge of the constituent primitive mechanisms, the overall configuration of a mechanism is described and identified by a spatial configuration state matrix. This matrix is obtained by using a qualitative reasoning method based on sign algebra and is used to represent the qualitative behavior of the mechanism. The matrix-based representation scheme allows handling the involved spatial knowledge simultaneously and the proposed reasoning method enables the designer to predict the spatial behavior of a mechanism without knowing specific dimension of the components of the mechanism.

  • This work is mainly done by too many manual operations in the aircraft structure design process resulting in heavy workload, low efficiency and quality, non-standardized processes and procedures. A top-down associated design method employing the template parametric technology is proposed here in order to improve the quality of design and efficiency of aircraft wing structure at the preliminary design stage. The appropriate parametric tool is chosen and the rapid design system of knowledge-driven aircraft wing structure is developed. First, a skeleton model of aircraft wing structure is rapidly built up through the template encapsulated design knowledge. Associated design is then introduced to realize the association between the typical structural part and skeleton model. Finally, the related elements are referenced from skeleton model, and a typical structural part reflecting an automatic response for design changes of the upstream skeleton model is quickly constructed within the template. The rapid design system proposed and developed in this paper is able to formalize the design standardization of aircraft wing structure and thus the rapid generation of different aircraft wing structure programs and achieve the structural design knowledge reuse as well.

  • As Korea's global IT sourcing is sluggish and supply of qualified IT personnel does not meet the demand, IT developers currently do not worry about their job security. The sluggish global sourcing is attributed to the lack of system design and analysis skills as well as lack of communication skills of IT personnel. Most of big Korean IT service firms operate in captive market. This is also attributed to the cause of the sluggish global sourcing. Some IT managers, especially in global IT service firms, concerned about the negative long term effect of the sluggish global sourcing on competitiveness and human infra capability of Korea's IT service industry. Managers in IT service firms expect skill requirement changes in the future when global sourcing becomes active. The skills and knowledge that they wish to retain in-house is business knowledge, system analysis and design knowledge, customer relation management skills, project management skills and industry knowledge. The jobs with the above knowledge usually involve customers.

  • The knowledge of the specialized fields has been changed rapidly in the both side of quantity and quality. A hyper media as a knowledge based system is so fixed in the linked media in mutual that we couldn't tell it information provision with the view of users. In this paper, we propose the way of offering intellectual and flexible information which is the same with demand in the side of user, selecting, searching and composing the hypertext at the point of user's view through the design of knowledge media system. Three concepts are used in order to challenge the knowledge media system : special document, agent system and ontology. The special document is a ensure that its activities are coordinated with those of the others within the community, providing a uniform control mechanism. Finally, ontology is a language for exchanging knowledgement, which is a message exchanged among agents to ensure the proper interaction among them. The combination of these three concepts is used to design the prototype of knowledge media system.

  • Modeling product configurations needs large amounts of knowledge about technical and marketing restrictions on the product. Previous attempts to automate product configurations concentrate on representations and management of the knowledge for specific domains in fixed and isolated computing environments. Since the knowledge about product configurations is subject to continuous change and hard to express, these attempts often failed to efficiently manage and exchange the knowledge in collaborative product development. In this paper, XML Topic Map (XTM) is introduced to represent and exchange the knowledge about product configurations in collaborative product development. A product configuration model based on XTM along with its merger and inference facilities enables configuration engineers In collaborative product development to manage and exchange their knowledge efficiently. An implementation of the proposed product configuration model is presented to demonstrate that the proposed approach enables enterprises to exchange the knowledge about product configurations during their collaborative product development.

  • The purpose of this study was to assess whether the osteoporosis preventive educational program has changed the middle-aged women's knowledge on osteoporosis. A one group pretest-posttest design was used. A total of 27 women (at pretest) and 27 women (at posttest) who were volunteers participated. The intervention program content included lecture and exercise entitled The Prevention of Osteoporosis. This program design consisted of one 3-hour session per week and lasted over 4-week period. Osteoporosis Knowledge Questionnaire (OKQ) was used. The OKQ contains 20 true-false items to measure the knowledge levels about osteoporosis. The Kuder-Richardson test (KR 20), used as an estimate of internal consistency for knowledge, was .7783. Overwhelming majority of the participants (96.2%) were ranging in age from 40 to 60. About half of the participants were college graduates and the majority of them (77.8%) had no jobs. The educational program significantly increased osteoporosis knowledge in middle-aged women. Results of this study shows that educational program is effective in increasing knowledge of osteoporosis. Further study using the same program with different age group is needed to measure knowledge, behavior and attitude on osteoporosis.
