In this research, a tool was developed for the rapid performance of three-dimensional finite element analysis (3D FEA) of a machine tool spindle system made of a shaft and bearings. It runs the FEA with data, such as the bearing stiffness and the coordinates of the points, to define the section of the shaft, bearing positions, and cutting point. developed for the spindle system and then implemented with the tool using an object-oriented programing technique that allows the use of the objects of the CAD system used in this research. Graphic user interfaces were designed for a user to interact with the tool. It provides rapid evaluation of the design of a spindle system, and therefore, it would be helpful to identify a near optimal design of a spindle system based on, say, static stiffness with design changes and, consequently, FEA.

This paper introduces the development of the analysis and design program of valve train system. In order to verify the stability of design and improve the performance of system efficiently, it is required that integrated and interactive simulation program. The presented program is developed in the base of the object-oriented, capsulation, modulization, OLE (objected linking and embedding) and various design theory. It contains the expandability and flexibility of the structure. In addition to that, it is programmed to make the convenient user interface by using the visualization programming. This program can support the modification of the valve element as well as the development of the valve train system in the beginning of design. It is expected to save the cost and time for the design of valve train system.

객체 지향 패러다임의 확산으로 인하여 소프트웨어 개발을 위한 객체 모델의 사용이 일반화되고 있다. 소프트웨어 요구사항의 분석 및 설계 결과로 생성되는 객체 모델은 소프트웨어의 구현 시에 많은 도움이 된다. 특히 작성된 객체 모델이 구체적인 경우에는 자동적인 원시 코드의 생성도 가능하다. 따라서 시스템 분석기나 설계자는 분석 단계 단계 초반기의 추상적인 객체 모델을 정제함으로써 구체적인 객체 모델을 유도하기 위해 많은 시간을 투입해야 한다. 그러나 추상적 객체 모델을 구체적 모델로 정제하는 과정은주 로 설계자의 비정형적인 경험에 의하여 이루어지는 것이 현실이다. 본 논문에서는 OMT(Object Modeling Technique)의 객체 모델을 대상으로 추상적 모델의 구체화 기법을 논한다. 따라서 본문에서 제시되는 주된 내용은 객체 모델의 추상화 정도에 대한 정희와 모델 의 변환 규칙에 대한 것이다. 이 변환 규칙은 정보 통신 서비스 개발 프로세스 모형화 개발 지원 도구의 일부분은 프로세스 모델러(Process Moedeler)의 설계시에 적용되고 있 으며 그 결과로 C++ 코드로 변환하기 쉬운 구체적 객체 모델을 얻을 수 있었다.

Agricultural facilities can be designed by conceptual preliminary primary and detailed design stages. because each stage has a different objective, it must be applied to dissimilar design and analysis level. Engineers have to judge from evaluation that is estimated agricultural resources in the conceptual design stage. Methods of computer aided design are achieved to individual functions however it is inefficient to perform entire processes of design and hard to systematically accumulate results o design. Study on the integrated structural design system has been continued. but those system have adopted “closed architecture”which is known to inflexible method for developing applications. In this study the design platform is an environment that can support to integrated design system independently and an design platform is proposed by analyzing design processes using object oriented method. The concepts of software platform have resulted from several practical ideas, OOA/OOP and related some points. This paper aims at developing the software platform of a software environment to support the design phases of the agricultural facilities.

The design of agricultural facilities is the consistent activities, which systematically analyze all the actual conditions, design the unit structures, and improve the faming environment through efficient organization of the unit facility. The design of agricultural facilities is composed of site study, preliminary design, primary design, and detail design. Integrated design system can manage and process the information created by and used in all steps of design process. Formal data models of these design activities are important conceptual steps in development of integrated design system. However, most of existing models are not available for agricultural facilities. To support efficiently developing the integrated design system of agricultural facilities, we have developed the Multi-Layered Primitive-Composite mode I through object-oriented analysis of agricultural facilities. The MPC model not only satisfies the characteristics of agricultural facility, such as variety, coupling, informal data, but also improves abilities of integrated design system such as extensibility, flexibility, and granularity. The paper presents a formal definition of the MPC model.

The first medical text in which detailed treatments of diseases by combinations of materia medica are mentioned is the "Shanghanzabinglun(傷寒雜病論)". True meaning of the combinations of materia medica used in this text lies in the fact that the efficacy of a prescription transcends that of the linear sum of each materia medica. This kind of concept regarding the composition of a prescription has come to contribute to the formation of theories in prescriptionology; However, it is difficult to analyze and interpret the meaning of each prescription separately because of differences in interpreting methods, points of view, and terminologies used by members of different academical branches. Therefore, it is desirable that one should understand a prescription as having been modified from a basic prescription, and then bring the interactions of ingredients into the picture, finally understanding the efficacy and chief virtues of the targeted prescription. Nevertheless, with the massive information of prescriptions, which exist in the format of texts, it is impossible to efficiently take advantage of prescription analyzing methods, and therefore the range of analysis extremely restricted. In order to overcomes these weaknesses, this paper suggests that object-oriented prescription database be constructed and that a search program for education and research that could facilitate an efficient access to the database be developed as well.

This paper presents a database approach to integrating the structural analysis and design processes for a typical shear wall apartment building design. Our initial efforts have focused on extracting various graphic information from CAD(AutoCAD™) systems. But now, we concentrate our research efforts on organizing specific information generated during the structural analysis and design processes. The proposed overall system consists of a conventional structural analysis package, a conventional CAD system, and different application interface programs. This system is based on an engineering database which is developed by using an object-oriented data modelling approach. The system is actually implemented on an ORACLE™-based relational database management system.
