  • 소프트웨어 개발 초기에 모든 요구사항을 정의하는 것은 불가능하기 때문에 요구사항은 소프트웨어 개발이 진행되는 동안에 지속적으로 변경된다. 이러한 요구사항 변경은 개발자가 소프트웨어 구조나 행위를 완벽하게 이해하지 못하거나 변경에 따라 영향을 받는 모든 부분을 식별할 수 없을 경우 많은 오류를 야기 시킨다. 그러므로, 조직의 비즈니스에 공헌하면서 비용 효과적으로 적절히 처리되기 위하여 요구사항은 관리되고 평가되어야한다. 본 논문은 가치분석을 통하여 생성된 휘처 기반의 요구사항추적 링크를 근간으로 하는 요구사항변경 관리 기법을 제안한다. 이는 사용자 요구사항과 산출물간의 연결을 분석하기 위하여 휘처를 중간 매개체로 활용한 추적 링크를 이용한다. 그리고, 요구사항 변경 요청을 휘처 단위로 상세화하기 위한 변경 트리 모델을 정의하고 변경 관리가 수행되는 전체적인 프로세스를 제시한다. 또한, 요구사항 변경 관리 기법을 자산관리포탈시스템에 적용한 사례의 결과를 기술한다.

  • 한국인정기구(KOLAS)는 시험 및 교정기관이 KS Q ISO/IEC 17025 요구사항에 맞추어 적절하게 운영하고 유효한 결과를 생산할 수 있도록 표준안을 제시하고 있다. 국가표준기본법(시험·검사: 시험·검사기관 인정, 교정: 국가교정제도의 확립)을 근거로 운영하고 있다. 최근, 국제시험소인정기구(ILAC)가 자격기준을 강화함에 따라 공인시험·교정기관들도 요구사항(KS Q ISO/IEC 17025:2017)에 맞추어 2020년 11월까지 전환을 완료해야 한다. 국내에서 운영되고 있는 899개 KOLAS 인정시험·검사와 교정기관이 여기에 해당된다. 여기에서는 적격성에 대한 주요 일반 요구사항을 요약하였다.

  • Four requirements for the operating and supporting system for sustainable landscape management will be discussed through this paper. The requirements are based on multiple case studies on the structure and the process of development of three organizations that have been contributing to the sustainable rural landscape management in Japan since 1989. The first requirement is that the residents should recognize regional problems and voluntarily organize a group which can properly deal with the problems. Secondly, members of the organization should have a solid grasp of the goal of their activities (or founding principal of the organization) and share it among themselves. Founding principal should include the history of natural circulation system in the area, cultural features and a future plan in association with human resources. Thirdly, the administration of the organization should be separated from the founder, the residents. The administration, such as business promotion, becomes more effective when consigned to a separate entity, not to the residents. Lastly, the interaction among separate entities is crucial to promote diverse activities for the local landscape management. The administrators and experts need to cooperate to draw a precise conclusion regarding the way of interaction. These requirements drawn from the Japanese case studies should be localized to the Korean circumstances for further adoption.

  • IEC 62278 presents a process to implement a consistent approach to the management of reliability for railway applications. A reliability program has to be established at the outset of a project in order to manage reliability activities effectively through the life cycle. The first step of the reliability program is to evaluate reliability requirements and targets based on the system specifications. The system specifications are derived from the customer's needs. The way in which the system requirements reflect the customer's needs is strongly dependent on the characteristics of the product. In general the customer of commercial trains presents the system requirements from their needs. However, the relation between the customer and supplier is equivocal for a project to development a prototype train, and the reliability program should be different from that of an usual commercial project. This paper deals with a process to manage reliability activities for the development of a protype train based on the experiences obtained from the development of the Korea High-Speed Train: Hanvit-350.

  • COMS On-board FDIR(Failure Detection, Isolation and Recovery) functions are implemented on the on-board software to satisfy the autonomy and failure tolerance requirements. This paper presents concepts of COMS Failure Management with hierarchical layers and addresses the characteristics of the FDIR layer from low level to high level. It is aimed at giving the reader the understanding how the COMS FDIR was designed and how works. It first recalls what are the system level applicable requirements, which are based on the COMS mission requirements. Then it describes the philosophy and structure of the FDIR and subsequently breaks it down into the several FDIR layers. It could be used as an important and useful reference of the information to design and develop an automatic FDIR mechanism in the future.

  • The complex documentation involved in power system analysis software require a well-defined and friendly database system. We have developed an object-oriented database management system for power system analysis, and have described load flow analysis and transient stability analysis using object-oriented database(OODB). Database management systems are widely used and achieve high reliability of data management in the engineering fields. However relational database system have shortcomings in application to power system analysis. ill relational database, the data model is too simple for modeling complex data and database languages are very different from programming languages. Object-oriented techniques are sufficiently powerful to support data-modeling requirements of GUI applications. The GUI is implemented using C++ on a MS windows platform. The OODB supports data modeling requirements of GUI applications and the performance is well acceptable for Gill applications.

  • ISO 15489:2001 addresses the principles and requirements with which organizations, both public and private, should comply on the management of their records to ensure that adequate records are created, captured and managed. The standard defines the characteristics that a record should have through records management system as follows: authenticity, reliability, integrity, and usability. Authenticity means that records can be proven to be what it purports to be, to have been created or sent by the person purported to have created or sent it, and to have been created or sent at the time purported. Reliability means that the contents of the records can be trusted as a full and accurate representation of the transactions, activities or facts to which they attest and can be depended upon in the course of subsequent transactions or activities. Integrity refers to ensuring that a record is complete and unaltered. Usability means that records can be located, retrieved, presented and interpreted. In order to have these characteristics, a record should be persistently linked to the metadata necessary to document a transaction. Metadata is "data describing context, content and structure of records and their management through time." Metadata ensure the creation and maintenance of authentic, reliable and usable records and the protection of the integrity of those records. It could be implemented by creating and capturing records management metadata in systems that create and manage records. There have been some projects and standard initiatives to identify a core set of records management metadata. Included are the Australian Recordkeeping Metadata Standard and the British Metadata Standard which is part of the Requirements for Electronic Records Management System. Recently ISO/TS 23081-1 is published to implement metadata requirements within the framework of ISO 15489. Public records management system in Korea is ruled by the Act on the Management of Archives by Public Agencies and Administrative Records Management Regulation. This article evaluates records and their descriptive elements captured and maintained by the records management system in Korea on the basis of the international metadata standards.

  • 표준 기록관리시스템(이하 RMS)은 기록관 또는 특수기록관에서 기록물관리를 전자적으로 수행하는 시스템이다. 그러나 현재 RMS는 일정부분 도입목적 및 사용자의 요구를 충족하지 못하고 있는 실정이다. 이는 사용자에 대한 교육 및 훈련 부족, RMS 세부기능에 대한 검토 부족이 원인이다. 따라서 본 연구는 RMS의 세부기능을 검토하여 RMS에 대한 평가기준을 설정하고 세부기능을 평가하는 것을 목표로 하였다. 특히 RMS의 주요 기능 중 연계인수기능을 평가대상으로 하였다. 본 연구에서 RMS의 연계인수기능을 평가하기 방안으로는 연계인수 기능의 7개의 세부기능을 검토하여 각각의 기능이 수행하는 업무 프로세스를 파악하는 방안을 적용하였다. 그리고 업무 프로세스 파악을 바탕으로 기능요건을 정의하고, 정의된 기능요건으로 체크리스트를 구성하여 기능준수여부를 설문하였다. 마지막으로 설문내용을 바탕으로 연계인수 기능에 대한 기능 구현 현황을 분석한 후 해외기록관리표준과 비교를 통해 RMS의 연계인수기능이 보여주는 시사점과 이에 대한 개선방안을 도출하였다.
