The purpose of this study is to develop an examination system for an e-learning quality manager's certificate which is composed of subjects, criteria, method of examination. The task model of e-learning quality manager was modify and task/knowledge/skill matrix was developed to design the examination system through conferences of DACUM committee and an advisory committee. And a survey was carry out to analyze validity of contents of the examination system. The major findings were as the follow: First, occupational specification, job specification, task specification and task/knowledge/skill matrix were developed. Second, examination subjects were developed based on task/knowledge/skill matrix, which were "Basis of e-Learning and plan of service", "Expulsion and management of e-learning infrastructure", "Development of e-learning contents", "Operation and evaluation of e-learning service". Third, the criteria and methods of examination for an e-learning quality manager's certificate were developed, which is composed of test type, the sum of test items, test time and acceptable standards.

Systems Engineering application focused on requirement definition and management for SURION System Development Project is described in this paper. To perform the development process effectively based on systems engineering processes; Requirements Definition, Design Review, Configuration Management, Quality Assurance, Data Management, are applied in this project. In this processes, the Stakeholder's Requirements are transferred to Specifications verified with design reviews, prototyping inspections, and integration tests. All engineering data, especially verification plan & results are recorded, and traced to each requirements of system specification in Surion database. Therefore, it could be assured that all requirements of specification are evaluated and verified successfully in Surion Project.

그레이팅(Grating)이라는 금속제품을 생산하는 5 업체에서는 설계 자동화 시스템인 GDS(Grating automatic Drawing System)를 통해 전체 설계도면(Plan Drawing)을 생성하고 GDS의 도면자료 자동생성 시스템(ASGS: Automatic Specification Generation System)을 통해 전체 도면상에 배치된 각각의 그레이팅에 대한 상세한 정보가 표현된 단품별 도면과 완성된 제품들에 대한 검사 기준을 표현한 검사도면을 생성하며 전체 제품에 대한 통계적인 정보를 생성한다. 그러나 도면자료 자동생성 시스템을 통해 자동 생성된 도면은 설계자들의 일반적인 치수 기입요령을 부분적으로 만족시키지 못하고 있으며 또 치수 표시간의 겹침 현상이 발생하여 설계자가 도면을 수정해야하는 번거로움이 있었다. 본 논문은 이러한 문제점을 해결하기 위해, 설계 전문가들의 치수 표시법을 지식으로 하는 규칙 기반 전문가 시스템을 구성하였다.

We, presently, don't have clear diagram methods and analysis criteria in rock bolt pull test usable for tunnel reinforcement. So this paper has suggested that; first, 'scheme of apposite diagram method at hard rock and the different application method of rock bolt pull test at weathered and hard rock', and second, 'the pullout capacity specification criteria for design and construction of rock bolt', based on foreign criteria and field test.

This paper describes an overall Noise Assurance Plan(NAP) in the project for developing a new rolling stock. In this paper, the procedure for implementing noise control activities for each development stage on the basis of the NAP is also described. The NAP was developed by KITECH(Korea Institute of Industrial Technology) and ODS(${\Phi}$degaard ＆ Danneskiold-Samsoe in DENMARK). Generally, the main objective of NAP is that noise assurance plan applies to the establishment of organization and personnel's roles and responsibilities, set-up of overall procedure and internal audit program. Here, a few comments are made to the deviations of the actual procedure(G7 Project) relative to the suggested NAP presented. The major difference between the suggested NAP and the actual procedure was the late involvement of the noise consultant resulting in suggestions for design improvements could not be implemented due to the advanced stage of the design. Similarly, the important task of preparing sub-supplier specifications was performed. The proposed NAP will be an efficient tool for noise management in the R＆D project for new rolling stock. Specially, in case that several companies and institutes are involoved in the R＆D team

Software productivity doesn't satisfy the need of service of software users and software quality isn't improved. Moreover, we still have difficulty in software maintenance. As a plan to counteract solving this crisis, the technology that is called CBSE or Componentware is introduced. Componet Based Software Architecture, one of the technologies associated with CBSE, as a structural description of system, describes both the components composed system of and interaction among these components. Software Architecture provides the technology and the methodology of composition among components in the field of CBSE. is accepted one of core technologies. In this thesis, we analyse information necessary for component specification and then proposed that component specificaton activities using formal specification language Z which is verified with the ability of analysis and logicality. The proposed activities are composed of 9 tasks. By presenting specific 11 products, it is also proposed that component specification activities which is the base of CBSD(ComponentBased Software Development) for reusing.

The Systems Engineering, as a methodology for engineering and management of today's ever-growing complex system, is a comprehensive and iterative problem-solving process. The process centers on the analysis and management of the stakeholders'needs throughout the entire Life-cycle of a system and searches for an optimized system architecture. There are many essential needs and requirements to be met when a system development task is carried out. Systems Engineering Management PLan(SEMP), as a specification for system development process, must be established to satisfy constraints and requirements of stakeholders successfully and to prevent cost overrun and schedule delay. The paper suggests a systematic SEMP development process and demonstrates a data model and schema for computer-aided systems engineering software, RDD-100, for use in the development and management of SEMP These are being applied to the systems engineering technology development task for the next-generation high-speed railway systems in progress.
