A repository has been conceived as a critical weapon for managing organizational information resources. The system can help control the heterogeneous data in a variety of CASE (Computer-Aided Software Engineering) tools. However, current repository systems have limitation in creating a synergetic effect by integrating information resources. Therefore, it is important to develop an integrative repository system, called Enterprise Repository System (ERS). This paper (i) defines ERS on the basis of a framework for repository systems, and (ii) suggests an ERS architecture and its detailed components. Finally, a real-life case of developing ERP repository system is illustrated according to the proposed architecture and components. This illustration may demonstrate the usefulness of this research for help developing an advanced repository system.

Successful start-ups are driven by opportunities, teams, and the resources needed to grow the business. Systematic business process management is required to maximize the efficiency of business operations. However, the existing entrepreneurial process research has limitations that it is difficult to intuitively and dynamically provide the necessary information for start-up operation, and it is necessary to define necessary information (resources, stakeholders, activities). In this study, we suggest the "Start-up Process Repository System" which overcomes limitations of existing entrepreneurial process research. The architecture for the Start-up Process Repository System provides five layers and enables each layer to interact four interfaces between each layer. This study improves start-ups' accessibility to the start-up business process repository created from the existing repository architecture and increases the utility derived from it by providing methodologies for components that offer useful start-up knowledge.

Workflow management system provides automation of job processes by maintaining shareability on information about various job process schedules and persons related to those schedules. Existing workflow management systems use file or database to store the information generated in those systems. However, file or database system could manage only non-complicated information for the workflow but not the information resources of an enterprise which is complicated and of various formats. Therefore, we need a data management system that could control those information resources. This system should manage the data which are distributed at several places geographically. Information Repository could meet those requirements. Information Repository may integrate, store and manage information resources requested by application systems. We have an international standard for the information repository, Information Resources Dictionary System(IRDS). The IRDS, however, does not support distributed environment. In this paper, we design and implement an information repository based on IRDS that may be operated in distributed environment. We verify that this information repository is more effective and is more effective than any other file or database system.

The requirement to reuse a design knowledge have been enlarged with the automation of a design system. A design knowledge gives logical and technical meanings to design data of a problem area. The representation of the knowledge is distributed and developed independently. For this reason, we need a general methodology with a semantic interoperability of design knowledge. In this paper, we accept previous requirements by using semantic query system with ontology repository.

기관 레포지토리는 오픈 엑세스 기반의 학술 커뮤니케이션을 실현할 뿐 아니라, 기관의 각종 지적 자산을 수집, 보존, 배포하기 위한 연구 도서관의 핵심 시설로 간주되고 있다. 우리나라에서도 운영 필요성을 인식해, 많은 대학 및 연구 기관이 도입하고 있으나, 레포지토리 운영 지원 및 실무자 연수 체계 미비로 아직까지 많은 기관에서 활성화되지 못하고 있다. 본 연구에서는 한국, 영국, 일본의 기관 레포지토리 실무자 연수 체계를 비교 분석하고, 국내 실무자들의 의견을 참고하여 레포지토리의 건전한 성장을 유도할 수 있는 연수 체계의 방향을 제안하였다. 실무자 연수 체계는 첫째, 기관 레포지토리의 역할과 본질을 이해하고 기관의 전폭적 지지를 유도할 수 있는 전략을 제시할 수 있어야 하며, 둘째, 컨텐츠 수집, 등록 정책뿐 아니라, 저작권 확인 절차와 같은 실무적 수준의 교육과 실습이 균형을 이루어야 하겠다. 마지막으로 시스템 운영 기술을 성숙시켜 나갈 수 있는 교육 프로그램의 제공과 기관간 기술 정보 공유의 장이 마련되어야 할 것이다.

Currently, many companies are trying to be more competitive by implementing the most appropriate software package, called ERP (Enterprise Resource Planning). ERP can support the company's business process. A repository, which can story and retrieve enterprise-wide information, is a key component of such software package. This paper implements an enterprise repository for the ERP. A wellknown repository standard, IRDS (Information Resource Dictionary System), is employed for the repository architecture. A meta schema that can help develop database, business applications, models, and workflow is proposed. To illustrate the practical usefulness, a real-life ERP prototype is built within the framework of the proposed repository.

최근 인터넷을 이용한 전자문서의 중요성이 부각되면서 대용량의 XML 문서에 대해 효율적으로 저장하고, 검색하며, 관리할 수 있는 XML 저장관리 시스템의 연구가 활발히 진행되고 있다. XML응용에서 특허 문서 관리, 소프트웨어 설계, 시스템 매뉴얼 등의 응용과 같이 수정된 기존의 문서들이 관리되어야 하는 분야에서 버전 관리 기능이 필요하다. 본 논문에서는 문서의 수정을 효율적으로 지원하는 분할모델을 이용하여 문서 수정에 따른 버전닝을 지원하는 데이터 모델을 제안한다. 또한 버전닝을 지원하는 XML 저장관리 시스템을 설계하고 구현한다. 구현한 시스템이 기존 저장 시스템 보다 더 우수하다는 것을 성능평가를 통해 보인다.

To use nuclear energy sustainably, spent nuclear fuel, classified as high-level radioactive waste and inevitably discharged after electricity generation by nuclear power plants, must be managed safely and isolated from the human environment. In Korea, the land area is limited and the amount of high-level radioactive waste, including spent nuclear fuels to be disposed, is relatively large. Thus, it is particularly necessary to maximize disposal efficiency. In this study, a high-efficiency deep geological repository concept was developed to enhance disposal efficiency. To this end, design strategies and requirements for a high-efficiency deep geological repository system were established, and engineered barrier modules with a disposal canister for pressurized water reactor (PWR)-type and pressurized heavy water reactor type Canada deuterium uranium (CANDU) plants were developed. Thermal and structural stability assessments were conducted for the repository system; it was confirmed that the system was suitable for the established strategies and requirements. In addition, the results of the nuclear safety assessment showed that the radiological safety of the new system met the Korean safety standards for disposal of high-level radioactive waste in terms of radiological dose. To evaluate disposal efficiency in terms of the disposal area, the layout of the developed disposal areas was assessed in terms of thermal limits. The estimated disposal areas were 2.51 km² and 1.82 km² (existing repository system: 4.57 km²) and the excavated host rock volumes were 2.7 Mm³ and 2.0 Mm³ (existing repository system: 4.5 Mm³) for thermal limits of 100 ℃ and 130 ℃, respectively. These results indicated that the area and the excavated volume of the new repository system were reduced by 40-60% compared to the existing repository system. In addition, methods to further improve the efficiency were derived for the disposal area for deep geological disposal of spent nuclear fuel. The results of this study are expected to be useful in establishing a national high-level radioactive waste management policy, and for the design of a commercial deep geological repository system for spent nuclear fuels.
