By managing various communication networks collectively, Telecommunication Management Network (TMN) has appeared as a concept to aim for the unified and effective communication network operation and maintenance. IMT-2000 and other network such as PSTN, cellular networks and packet witching network that are integrated with IMT-2000 have been developed in different platforms - hardware and operating system, and a same circumstance will happen in the maintenance in the future. Also, it is difficult to approach to the standard for Ｑ3 interface implementation of the agent in TMN system that may occur in the development or the maintenance for the different platform of IMT-2000 and other networks that are integrated with IMT-2000. In order to solve this kind of Problems, this Paper suggests integrated network management agent of IMT-2000 based on the NTS model and Advanced Intelligent Network(AIN).

In competitive electricity markets, each GenCo establishes generator maintenance schedule and submits to ISO those. Then, ISO reviews and arranges maintenance schedule of each GenCo to meet the standard for reliability. This paper presents the new optimization model which can apply to competitive electricity markets. The object of this model is to minimize schedules variation of each GenCo and to satisfy system reliability.

Plant life cycle consists of design, construction, certification, operation, and maintenance phases, and various and enormous plant life cycle data is involved in each phase. Plant life cycle data should be linked with each other based on its proper relationships, so that plant operators can access necessary plant data during their regular operations and maintenance works. Currently, the relationships of plant life cycle data may not be defined explicitly, or they are scattered over several plant information systems. This paper proposes high level design of a plant life cycle data management system based on pre-defined plant life cycle database design. ISO-15926 standard is adapted for the database design. User-interface designs of the plant life cycle data management system are explained based on analysis of plant owners' requirements. A conceptual design of the database is also described with the entity-relationship diagram.

In this paper, a study an standardization of control cable numbering for high speed railway substation. Standard numbering structure of substation control cable and consistency of the number system are important for the railway substation construction and maintenance. However, currently control cable number system of railway substation was not standardization which was different according to a bander and a construct company. Therefor there is many difficult which does a same function to differ in maintenance and repair to accident. Therefor Standardizes the number system of the substation control cable is useful for an improve of construction and maintenance.

In medium and small firm, the management system which is simple and where there is a practicality is required Ill)re than the management system which is complicated and minute of the centered around large company so that the introduction of the standard costs can be activated and it can be usefully used as a tool of management decisions. A difference between the standard costs introduction plan proposed in this paper and the preexistance study literature are as follows. In this paper, by breaking from the whole cost accounting aiming at all item, that is the traditional introduction method, and presenting the product cost accounting method by group the standards setting object was minimized and simplified. In this way, if the standards setting object is simplified, it is quick at the perimeter environment change as the little man power and flexibly it corresponds to and the cost information calculation which is exact with the setting up and maintenance of the efficient cost standard becomes available. As a result of applying for real through S corp., the usability of the method that the standard costs introduction method proposed in this paper produced the standard costs relatively short within period, it manages was verified. And the standard costs introduction method proposed in this paper went by the various cost information for each products, the management class did the management will decision which was objective and reasonable in the putting first.

화학설비의 노후화·고도화·복합화 등으로 인해 설비의 점검, 보수 또는 정비 작업 등의 비일상 작업이 증가하고 있으며, PSM 대상 화학제품제조업 사업장에서의 지난 10년간 발생한 1,483건의 사고 중 비일상 작업 중에 발생한 사고가 전체의 56%(932건)를 차지하여 일상 작업보다는 비일상 작업 중에 더 많은 사고가 발생하는 것을 확인할 수 있다. 특히 공장 운전의 경제성 및 효율성을 위하여 공장 전체를 정지시키지 않고 일부 설비를 정지시킨 후 운전 중인 설비와는 격리한 상태로 점검, 보수 또는 정비 작업을 수행하는 경우가 있다. 따라서 첫째, 화학공장의 취급물질, 운전조건, 설비의 위험도 등을 기준으로 격리 표준(Baseline Isolation Standard)을 수립하여 안전한 격리 방안을 선정하여야 한다. 둘째, 현재 국내 법규 및 기준 상에는 구체적인 격리 표준의 필요성을 제시하지 않고 있으므로 격리 표준의 마련을 제도화하는 것이 필요하다. 이러한 기술적·제도적 개선을 통하여 화학공장 설비에서의 화학물질의 누출에 의한 화재·폭발·중독 사고를 예 방하여야 한다.

이 연구의 목적은 항공 정비사의 업무수행능력이 항공운항의 안전 및 효율에 큰 영향을 미치고 있는 추세를 반영하여 항공정비인적요인 교육훈련기준을 수립하는데 있다. 이를 위해 인적요인의 개념에 대한 선행연구들을 고찰하였으며, 국제민간항공기구(ICAO), 미연방항공청(FAA) 및 유럽항공안전청(EASA) 등의 선진해외항공국의 인적요인 교육훈련기준과 우리나라 항공안전법의 운항기술기준과 비교분석하였다. 또한 2곳의 대형항공사(FSC)와 4곳의 저비용항공사(LCC)의 인적요인 교육훈련실태를 조사하였다. 본 연구를 통해 우리나라의 인적요인 교육훈련기준이 국제기준에 비해 미약한 것으로 나타났으며, 대부분의 항공사 또한 인적요인 교육훈련을 체계적으로 실시하지 못하고 있는 것을 확인할 수 있었다. 이러한 연구 성과를 통해 현행 우리나라 항공정비인적요인 교육훈련기준의 문제점을 보완하고, 국제기준에 적합한 항공정비인적요인 교육과정의 표준모델을 제시할 수 있었다.

육군의 화력장비 정비교육 중 특기병 교육은 실습용 장비가 부족하고 많은 교육생으로 실습기회가 적고 정비실습 시 안전사고 발생위험이 높아 실질적인 실습이 제한적이고 반복 실습이 어렵기 때문에 교육적 효과가 미비한 게 현실이다. 따라서 실제와 같은 체험훈련으로 교육성과를 높이는 훈련시스템이 필요하다. 본 연구에서는 시공간을 초월하여 훈련비용을 낮추고 실제와 같은 체험훈련을 할 수 있으며, 표준 정비매뉴얼이 반영되고 팀워크를 이루어 훈련할 수 있는 가상훈련시스템을 제안한다. 가상훈련시스템은 시공간을 초월하여 비용을 낮추고 실제와 같은 훈련이 가능한 시스템으로 본 연구에서 제안한 3차원 디스플레이 시스템인 HMD를 이용한 1인칭 시점의 가상훈련시스템은 육군 화력장비 정비교육에 적합한 시스템이며 확장성이 좋기 때문에 다른 장비와 타군의 정비교육에도 활용되어 군의 정비능력 향상에 크게 도움이 될 것으로 기대한다.
