ebXML is the international technical framework specification that enables Internet-based B2B electronic business using XML, It was standardized by UN/CEFACT and OASIS on May 2001. Registry and Repository is the core of ebXML. It supports registry services which is composed of object management service and object query management service. The object management service manages the object's life cycle and the object query management service provides a mechanism to approach metadata of stored objects. Up to now, implementations of ebXML Registry object query management system don't support full functions of the specification completely. We implemented all the functions of ebXML Registry Service Specification vl.0. This system supports Browse ＆ Drilldown Query, Filter Query, SQL Query, and Object Retrieval Query services. And it also supports Content-based Query service which is not specified in the ebXML RS specification. The Content-based Query service is a repository service which makes it possible In pose content based queries of repository items and which will be specified on the RS specification v2.0.

Recently, a railroad system has a big and complicated structure of specification. Therefore, traceability between specification need to be identified for design change management and this is many engineer's concerns. Traceability means technical relationship. This is to trace other specification or component connect with relevant problem in case some problem should be examined. Traceability between functional specification can be proved through functional analysis essentially. This study will introduce an application method of functional analysis in the case of practical use project of MAGLEV train. And we propose the guide to identify traceability between function through functional analysis.

블루투스는 정보, 가전 및 산전기기 등의 복잡한 통신 케이블 대체용으로 개발된 무선통신 규격 또는 그 규격을 사용한 제품을 말하는 것으로 무선통신의 이동성과 간편성에 힘입어 여러 근거리 통신 응용분야에서 많은 변화를 불러 올 것으로 기대되었다. 하지만, 최근 블루투스 본연의 기능에 충실하기보다는 이동통신 대체수단으로 기획됨에 따라 이의 실효성에 의문점이 시사되고 있으며, 이에 대한 장기적인 발전 전망이 요구되는 시점이다. 본 연구에서는 블루투스 기술기준을 충심으로 블루투스의 현황을 점검하고 향후 블루투스의 발전방향을 예측, 기술기준적 측면에서 제도적 지원방향을 제안하였다.

The utility and the nuclear research institutes in korea have conducted research for improving inefficient requirements in technical specifications using the results of probability risk assessments and informations with risk. However, the guidance for reviewing the improved technical specifications has not been developed. The objective of this study is to develop a decision-making framework for investigating and reviewing the technical documents associated with the to changes of technical specification This study has developed a decision-making framework for reviewing the improvements of the RI-TS(Risk-Informed Technical Specifications). This work may contribute to enhancing both the safety and the efficiency of nuclear power plants by changing Technical Specifications proposed by the utility.

Light rail vehicle is optimized vehicle system for complex urban circumstance. LRT systems have many merits such as improve accuracy, speediness and safety. There are many LRT systems such as monorail, tram, automated guideway transit, linear induction motor propulsion and so on. These systems have operated in Japan and other advanced countries. In Korea, local government has many projects to apply the advanced LRT system. But there are no standardized specification, performance test specification, construction specification for monorail system, linear induction motor propulsion system, tram in Korea up to now. So, we need to establish of standardized to economical construction and safety. The linear induction motor system has been usually applied in Japan subway and ART(Advanced Rapid Transit) of Canada. In Korea, the linear induction motor system has been adopted for Yongin LRT and currently under construction. This paper covers the contents and technical base for main items of rolling stock, performance standard, carbody structure, bogie, electronic unit and brake equipment in order to implement linear induction motor LRT system according to local conditions.

This paper suggested that the technical specification of tilting train EMU for speed up on existing lines. High speed strategy of existing lines are the modification of railway system which are made on cant, lengths of transition curves, the catenary system and train system. Tilting technology is more useful a strategy for speed increases on existing lines with low investment needed. We performed a feasibility study which is considered out real track conditions and designed propulsion and braking system of tilting EMU system.

The Honam conventional railroad was already exceseed the limit capacity of transportal ion at some sect ion. Therefore Honam railroad axis needs new high speed railroad line for increasing of transportal ion capacity now. This report was studied about the system technical specification of rolling stock based on new technology or high speed train or advenced countries, KHST and KTX for Honam high speed railroad.
