In the modern design technology, a component should be designed to fit into the overall system performance. A design methodology is developed to expedite the mechan- ical design of complex mechanical systems, The relation between the system design and component design is defined by a top-down approach and the results from the system design are utilized in the component design process. As a design example, an automobile exhaust system is selected for the system design and a bellows is chosen for a component design. Design methodology based on the top-down approach consists of five steps; (1) Analysis of service load, (2) Development of a lumped parameter, (3) Completion of the system design, (4) Selection of the component topology, (5) Completion of the component design, A method using a equivalent matrix is developed in order to determine unknown external forces in linear structural analyses. The bellows is also analyzed by the finite element method using a conical frustum shell element. Various experiments are performed to verify the developed theories. The top-down desi- gn approach is demonstrated by a design case using structural and shape optimization technology. Since the method is relatively simple and easy compared to other methods, it can be applied to the general design where system and component designs are involves simultaneously.

Recently, business application vendors have responded to customer demand with several technological and organizational changes for reflecting network-oriented process flow with electronic communication and expanding their market. In organizational changes. Vendors are adding new functionality to their core offerings through mergers and acquisitions, or by partnering with front-office operation and SCM vendors. And technological changes are embracing the development of component-based application and middleware technology to be possible with integration of their function modules. We will present the design and development process of component-based SCM system to be integrated with heterogeneous ERP under implementation. Especially, we survey and analyze the technology related with CBD(Component-Based Development) to be adapted this research - component's design and methodology, the interface for component integration, middleware's development methodology of Enterprise Middleware vendo to bundle various types of middleware into a single package product with easy-to-use interface.

The objective of this paper is to systematically establish the development of game software through the fusion of game implementation and component methodology. The development of game software has inconsistently accomplished without the consistent frame for the analysis and design of game development in the domestic environments. Therefore in case of the development of game software based on game component, although a lot of resources were required in the initial the accumulation of experience and the technology of reuse lead to the efficiency of the maintenance ultimately.

Manufacturing firms have adapted seriously the Design for Manufacture and Assembly (DFMA) techniques which consider concurrently all factors related to the product development by using effective communications and sharing of information on product development processes. This study performed modelling and characterizing the data related to product manufacturing information for Design for Manufacture(DFM) evaluation and analysis. It adapted component-based development method for communicating and managing manufacturing information among distributed manufacturing organizations. Introducing component-based development offers safety and speed to network based system. This development using Unified Modelling Language(UML) provides efficient way for reconstruction and distribution of applications. Also, the integration of database and component into the internet environment enables to communicate and manage effectively manufacturing information for DFM evaluation and analysis at any place in the world. Therefore this system can make it more reasonable that evaluating, analyzing, and effective decision making of product design using DFM technique.

소프트웨어 개발의 높은 생산성을 향상시키기 위한 재사용 기술로 컴포넌트 기반 개발 방법론은 널리 사용되게 되었다. 컴포넌트의 재사용을 향상시키기 위해서는 설계된 컴포넌트가 측정가능 해야 하므로 컴포넌트의 품질을 정량적으로 평가할 메트릭스가 필요하다. 따라서 본 논문에서는 컴포넌트의 특성을 반영한 컴포넌트의 결합도 메트릭을 제안한다. 또한 제안된 결합도 메트릭의 정확성을 검증하기 위해 사례연구를 제시하고 기존 결합도 메트릭스와의 비교 분석 결과를 제시한다. 제안된 결합도 메트릭은 좀 더 정확하게 컴포넌트의 품질을 평가하고 Briand이 제시한 결합도 메트릭의 필요조건을 만족한다.

Today, E-Business develop because, Internet diffuse rapidly. Variety function and excellence performance needs for changeable user's requirement. So, EJB comes Component's addition and modify. For Component adds Function, Existing System modifies all of the source code. In EJB Component System, but, modifies simple source code. But, Today's System don't have cleary way that assembly component and design system. This Paper used design pattern for maintain of the component. this paper describes EJB Design Pattern using Abstract Factory Pattern. And EJB Component that used Pattern, decribes advantage and disavantage.

최근의 소프트웨어 개발 기술은 조립 가능한 컴포넌트를 모아 복잡한 소프트웨어 시스템을 만드는 것을 가능하게 하고 있다. 그러나 효율성, 신뢰성이 있는 동적 형상을 지원하는 컴포넌트 기반 시스템을 개발하기에는 어려움이 있다. 컴포넌트에 대한 명세화 되지 않은 의존과 행위가 실체의 원인이 되고 있다. 따라서 컴포넌트 기반 소프트웨어 시스템은 컴포넌트간의 의존성 및 컴포넌트 요구사항을 표현하는 명백한 유지가 있어야 한다. 본 논문은 컴포넌트 서비스에서 배치, 상태보고 및 제어를 위한 컴포넌트 서비스 레포지토리를 설계하고, 기존에 연구된 컴포넌트 의존성 알고리즘의 커스터마이징을 통하여 동적 의존성을 지원하는 재형상 인터페이스 알고리즘을 제안하여 응용 프로그램의 다른 문맥을 재사용 할 수 있도록 하였다.

Recently, various network protocols have been developed to keep step with the rapid growth of Internet users. For the education of students in the computer networks classes, there have been many attempts to allow students experiment routers setting, operations and management of networks by themselves, in addition to the classroom lectures based on textbooks. One of the attempts is to install expensive real router experiment sets in laboratories for students, and one another is using router and network simulators for virtual experiments. This paper presents the design and implementation of NetSim, a scalable, component-based simulator environment for the network experimentation. NetSim expands the existing component-based JavaSim simulation tool for the education purpose, and it allows the design and experiment of various networks and protocols. For the evaluation of NetSim, it is shown that the network design and RIP-based router setting process is possible in NetSim.

The CORBA that supports FPGA has not been used generally and it is difficult to implement and to develop the CORBA for FPGA. In this paper we propose the way to design FPGA to support a CORBA component. For FPGA to support the CORBA component, embedded processor provided by FPGA and PCI based CORBA is utilized. The PCI based CORBA is for improving data transfer throughput. This paper will be organized as follows. In Chapter I, existing research trend and background are presented for why we propose design of FPGA that support the CORBA component. In Chapter II, FPGA design for supporting CORBA components is proposed and described in detail. In Chapter III, simple experiment is tested to confirm the proposed FPGA design. Finally session 4 is conclusion of this paper.

소프트웨어 개발의 독립성과 높은 생산성을 향상시키기 위한 재사용 기술로 컴포넌트 기반 개발 방법론은 널리 사용되게 되었다. 소프트웨어의 품질을 향상시키기 위해서는 측정 가능해야 하므로, 컴포넌트의 특성을 반영한 컴포넌트 메트릭스가 필요하다. 따라서 본 논문에서는 컴포넌트 기반 시스템의 컴포넌트 설계 정보에 기반한 컴포넌트 응집도와 결합도 메트릭스를 제안한다. 오퍼레이션이 컴포넌트의 서비스를 제공하기 위해 공통으로 사용하는 클래스에 대한 정보를 이용해 오퍼레이션 사용도를 구하고, 이를 통해 오퍼레이션 유사도를 구한다. 컴포넌트 응집도와 결합도는 오퍼레이션 유사도에 의해 계산되며, 컴포넌트 분석 단계에 추출 가능한 정보로부터 계산된다. 그리고 사례 연구를 통해 컴포넌트 메트릭스의 필요성을 객체지향 메트릭스와의 비교를 통해 살펴본다.
