In the aspect of the nature of aircraft maintenance work on divisible tasks carried out by a wide range of operation and expertise, any information transmission problems will not only cause a threat to flight safety but also reduce productivity by keeping the team from fulfilling its mission of delivering aircraft with airworthiness. In this regard, this study firstly identify the current status of information of aircraft maintenance and factors disturbing information transmission. Then, this article also find out the level of information culture of the AMT(Aircraft Maintenance Technicians) and problems in using information. Finally, suggestions on the model of the positive information culture in a field of aircraft maintenance through efficient use of the information including safety will be followed.

Knowledge management system building knowledge acquisition, knowledge share, and knowledge maintenance for the member of corporation is expanded throughout whole industry to cope with rapid business environment. Electronic document basing knowledge management system can copy, print, and transfer knowledge to another party, so it is being regarded as a essential infrastructure to share knowledge. However, considering most of information leakage is sprung up by insider of organization, it is considered to provide countermeasure to protect illegal use from information leakage. The purpose of this paper is to establish digital information security system through design of document and manage digital information assets safely through electronic document security system protecting illegal leakage of digital information assets.

이 연구는 점자도서관 문서 생산과 관리의 실태파악을 하고, 개선방안을 제시하는 것을 목표로 하고 있다. 이 연구는 3개 기관을 현장조사와 면담을 실시하였고, ISO 15489의 품질요건을 기준으로 분석했다. 그 결과, 점자도서관 문서 관리 개선방안은 다음과 같다. 첫째, 정책 및 규정 정비가 필요하다. 사본 생산과 관리에 관한 규정, 접근권한과 관련된 문서 관리규정의 마련이 요구된다. 둘째, 문서 생산 프로세스 개선이 필요하다. 시각장애인의 책임 있는 생산을 위해 Electronic approval system을 도입하고, 문서 생산 시 시각장애인이 읽을 수 있는 문서를 함께 생산, 그리고 문서철에 점자라벨을 부착하는 방안도 마련되어야 할 것이다. 셋째, 문서 관리 프로세스 개선이 필요하다. 사본 생산 시 변경 내역을 기록하고, 원본과 사본의 보존기간을 동일하게 부여하여 함께 보존하고, 모든 사본을 진본사본으로 정하여 하나의 세트로 관리하는 방안도 필요하다. 마지막으로 문서관리를 위한 시스템 도입이 필요하다. 체계적인 문서 관리를 할 수 있는 시스템 도입이 요구된다. 이 시스템은 시각 장애인이 접근, 검색이 가능하도록 설계되어야 할 것이다.

The purpose of this paper is to review concerns and activities related to the library of Germany as well as to look over recent trends referred to the maintenance of the library and its information service system since the unification of Germany in 1990. In fact, since the unification, many libraries in old East Germany have been closed with some precious books being lost. Also since most of libraries are short of funds and proper materials, it is real situation that they can not actively respond to the demand of information by library users who want to adapt themselves to changes, while only urgently requesting some support from old West Germany. In the meantime, the new government and libraries of Germany are giving a great effort to building an efficient document delivery system through financial support for the expansion of books and the purchase of urgently necessary library equipments in the poor libraries of old East Germany and support for the course to re-educate the in-service or unemployeed librarians, and also systematic organization between similar libraries, integration of national bibliographies, and maintenance of the interlibrary loan system. The nationwide interlibrary loan system, an expanded form of the system of old West Germany, allows the delivery of document to be easily performed, centered on both central cataloues for East Germany and West. However, in order to build an efficient information service system which covers whole Germany, it seems there needs more time required.

We need to make the standards of maintenance information for urban transit to reduce the cost to maintain the information and to share the information with maintenance workers. It is enable to do systematic maintenance for urban transit by using the information system based on the standardized information. In this paper we propose the major items to standardize and the methods to lay out the standard schemes to enable structured maintenance. We present the 4 items, bill of material, material classification, accident/fault classification, electronic document, to standardize. And we propose how to implement the information system for urban transit based on the standardized information. We describe the implemented information system in two parts; a rolling-stock and an infrastructure part. And also we describe the result of survey to evaluate the system installed at Seoul Metro and Seoul Metropolitan Rapid Transit.

Life cycle costing is one of the most effective approaches for the cost analysis of long-term life products, like as railroad vehicle. Life cycle costing includes the cost of concept design, development, manufacture, operating, maintenance and disposal. Especially, life cycle costing in the railroad industry has been focused on the maintenance cost. In this paper, we investigated the standard, guide and maintenance information of railroad vehicle. For this purpose, we suggested the unique templates of railroad vehicle maintenance information. We also performed maintenance cost analysis on the some sub-system of railroad vehicle for the case study.

본 연구에서는 HTML이나 XML로 작성한 Web 문서들의 복잡도를 측정하는 모델을 제안한다, 문서들의 복잡도는 문서들을 이해하는 데 밀접한 영향을 미치고, 이 이해도가 높은 Web 문서들은 결국 WEI에 좋은 효과를 거둘 수 있다. 본 연구에서 제안한 복잡도는 Web 문서들 간의 주고받는 정보의 흐름의 정도를 표현하기 위하여 엔트로피의 함수를 이용한다. 제안한 문서 복잡도는 문서들간의 정보 이동 관계에 의해서 문서들 내의 정보 흐름을 측정한다. 논 연구에서 제안한 문서 복잡도의 타당도는 Weyuker가 제안한 프로그램의 복잡도 평가 방법을 이용하여 평가하였고, 실제 문서들의 복잡도를 측정하였다. 또한 문서화일의 수와 문서 복잡도간의 상관관계를 분석하여 본 연구에서 제안한 문서 복잡도의 효율성을 제시하였다.

This study provides a new operation strategy which can guarantee the data consistency of engineering information among the various intelligent information systems. We present the strategies for the operation of bridges engineering information and the construction methodology of integrated database. The two core standard techniques are adopted to construct the integrated database. One of these standards is the Standard for the Exchange of Product Model Data (STEP) for CAD/CAE information and the other is the Extensible Markup Language (XML) for engineering document information. This study can transform a document me into a data type for web-based application modules which assist end-users in searching and retrieval of engineering document data. In addition, relaying algorithm is developed to integrate the two different information, e.g. CAD/CAE information and engineering document information. The pilot application modules for management and maintenance of existing bridge are also developed to show application of the strategy.

Most urban transit companies recognize the necessity of classification for facility management Classification for urban transit facility is necessary for standardization of maintenance management. The practical application. however. is not easy because of the absence of standardization of classification for urban transit facility and the difficulty in objectification of breakdown structure. This study suggests a proposal of classification for maintenance management in urban transit facility. This study defines standardization of classification as facility, work, maintenance and attribute to manage urban transit facility. And attribute classification consist of material, equipment and document. The suggested classification can be used as a useful maintenance management tool that enables evaluation of urban transit facility by standardization. The results of this study could be used as references for related urban transit companies.

This study attempts to estimate economic benefits in terms of cost sayings and qualitative effects resulting ken implementation of new vehicle maintenance information system. It is widely expected that the effect of new vehicle maintenance information system will be significant in cost savings by information sharing and electronic documentation. To evaluate the economic feasibility of new system implementation, the study conducted seven subsystems case studies on the vehicle maintenance information system of Seoul Metro. Economic benefits are estimated by measuring the time savings, in turn, are calculated into cost savings by multiplying the average wages per hour of employee. The result of case study showed that over the 20 billion Won will be saved owing to new vehicle information system implementation. In conclusion, this study will contribute to the field of practices for the most, in evaluation of the economic benefits resulting from new information system implementation in the railway organization.
