Naval ships are complex weapon systems which play the integrated performance by system integration of many kinds of weapon systems and their leading ships are usually not disposed after test and evaluation but militarised. Then, strict project management is required for naval ship building projects by identifying problems early and by taking prefer measures in time against unexpected situations encountered in the process of the projects. EVMS is a project management system which can manage the schedule and the budget of a project concurrently and estimate the project's time duration and the cost at project completion. In this paper, the applicability and usefulness of WMS is studied for a assumed navai ship building project, in the environment of monetary fluctuations such as price index, wage increase rate and exchange rate.

Urban railway signaling system is for train operation with safety in the urban crowded area, that has been increasing the demand of use of advanced train control systems with safe. European Commission is supporting the UGTMS(Urban Guided Transport Management System) project for the research and development. The main objective of UGTMS is to provide the European urban guided transport sector (comprising metro, tram and light rail systems) with a common Management System. A key topic is the extent to which the specifications for the successful ERTMS(European Rail Transport Management System) can be adapted to UGTMS needs. Beyond this, it is necessary to define the relevant functional and system requirements for all types of urban guided transport management systems in order to improve interoperability and intermodality. Also to be explored are the prospects for open system standards. In this article, we look into the trend of the standardization through the UGTMS project in Europe and consider any benefit to the project of the standardization for the urban railway signaling system in Korea.

This paper presents the methods to acquire the Safety Certificate from Independent Safety Assessment based on the IEC standard62279 which is commonly applied to railway system for Automatic Train Control(ATC) system in accordance with Urban Maglev project. This also shows approach methods and relative activities for project life-cycle to accomplish and ensure the system requirements of ATC system, RAMS and S/W quality activities. Furthermore, the key tasks conducted with ISA are noted in detail. These kind of activities for software quality of ATC system to obtain Safety Certificate could be a CASE model to improve the quality of domestic railway system and products, and also contribute to the growth of railway business and toward the achievement of overseas' railway signaling markets.

Civil engineering construction work has always been accompanied by a high proportion of tasks that are either dangerous or unpleasant or both. Enhancing the general working environment and boosting safety levels are critical issues for the industry. In addition to that, the industry has been slow to utilize automation & robot technology, and there is substantial scope for the use of technology th boost efficiency, cut costs and improve quality levels in construction. In a bid to address this issue, Ministry of Construction & Transportation launched a five-year project in 2003 entitled Development of Intelligent Excavating System. The aim of the project is to use telecommunications and robotics technology to minimize inefficiencies and eliminate the dangerous and unpleasant aspects of tile construction process through the development of specific applications such as IT-equipped construction machinery and advanced construction management systems. In this paper, the project introduces on the research and development content related to multi-disciplinary, a intuitive operator control unit(Robot Technology) included.

기초과학연구원 중이온가속기구축사업단에서는 희귀동위원소(Rare Isotopes, RI) 빔의 생성 및 분리를 위한 ISOL(Isotope Separation On Line) 시스템의 설치 및 성능시험이 진행 중에 있다. ISOL 표적/이온원에서 생성된 다양한 RI 빔은 빔 전송장치 및 분리 장치를 거쳐 사용자가 원하는 RI 빔만 선별되어 ISOL 후단의 초전도 선형가속기로 전송된다. ISOL 시스템에서는 특정 RI 빔을 분리하기 위해 두 개의 분리 장치가 설치되어 있으며 EPICS(Experimental Physics and Industrial Control System)에 의해 제어가 이루어진다. 본 연구에서는 ISOL RI 빔 분리 장치 중 하나인 A/Q 분리기에서 다가(n+) RI 빔의 질량선별을 위해 이극자석의 자기장을 측정하기 위한 EPICS IOC(Input-Output Control)를 개발하였으며, 홀 프로브(Hall Probe)를 이용한 자기장 측정 실험을 통해 A/Q 분리기의 운전 안정성에 대해 평가하였다.

As the railway becomes higher, the reliable stability and riding comfort of higher railway are required. To improve the riding comfort of high-speed trains, it is very helpful to use active suspension system for railway. In Japan, the high-speed train, Shinkansen has adopted semi-active suspension system and now it is running in the main trunk. In this paper, the authors introduce several technical trends of vibration control methods of Japanese Shinkansen. And the installation of semi-active suspension to HSR 350x and the test result of test run on the Kyoung-Bu high speed ling are also explained. After development of HSR 350x, new R&D national project of high speed train is progressed by Ministry of Land, Transport, and Maritime Affairs. This project is the development of Electric Multiple Unit of high speed train with 400km/h of maximum test speed. These result would be helpful to progress next generation high speed project.

지적 분야의 세계측지계 도입은 "측량 수로조사 및 지적에 관한 법률"의 제정을 계기로 본격 시행될 예정이다. 그러나 우리나라의 지적측량기준점은 여러 가지 이유로 인해 그 성과가 균질하지 못하며 국가기준점과도 일치되지 않는 문제를 내포하고 있다. 따라서 본 연구는 약 20,000여점에 달하는 지적기준점의 일제조사를 통해 국가기준점인 GPS기준점과 연동될 수 있는 약 1,600점의 기준점을 선별하고 이렇게 선별된 기준점에 대한 정확한 세계측지계 성과산출을 통해 지적측량을 위한 단일 관측망을 구축함으로써 향후 추진하게 될 전국 규모의 지적재조사 시행기반의 효과적 조성에 기여하는데 연구의 주안점을 두었다.

Increasingly, risk analysis is becoming important ingredients in achieving the successful implementation and application in the area of the project management. The project management system is designed to manage or control the project resources on a given activity within time, cost and performance so called TPPM (Total Productive Project Management). In this research, a risk analysis model misproposed to identify potential problem areas, quantify the risks, and generated the chice of the action that can be taken to reduce the risk. In addition two analysis models are proposed : 1) risk factor model and 2) network simulation model using VERT (Venture Evaluation and Review Technique ). The objective of the remodels is to estimate the schedule, cost performance risks. These proposed quantitative models for project risk analysis are proving its value for the project managers who need to assess the risk of changes in cost, schedule, or performance. The proposed models will be used in the area of project selection, evaluation and the allocation of project resources.

건설공사관리체계는 실적자료를 바탕으로 운영되어야 하며, 공사실적을 정확하게 파악하기 위해서는 합리적인 건설공사진도 율 측정기준 및 그에 따른 진도 율 산정방법이 필요하다. 본 연구에서는 건설공사관리체계 구축에 필수적인 건설공사진도율 산정시스템 개발 및 그 시스템의 합리적인 운용 방안을 제시하였다. 그 방법으로서 분할된 단위작업들은 공사 진행에 따라 집행된 내역물량을 기준으로, 상위레벨의 작업범위에 대하여는 실행기성(earned value)을 바탕으로 건설공사의 진도 율을 산정 할 수 있는 시스템(construction progress measurement system; CPMS)을 제시하였다 일반 PC의 Window환경에서 제공되는 프로그래밍 인터페이스(interface) 기능인 ODBC(Open DataBase Connectivity)는 상이한 프로그램간의 데이터 교환을 통해 정보공유를 가능케 하고 있다 본 연구에서 제시하는 건설공사진도 율 산정 시스템은 ODBC를 통해, 상용 일정관리프로그램을 활용해서 생성된 데이터를 그대로 이용하고, 시스템 내에서 생성된 데이터는 일정관리프로그램에 갱신(update)된 정보로 제공된다. 제안된 건설공사진도 율 측정시스템의 실용화를 촉진시키기 위해서는 진도 율 측정에 의한 수치 값을 분석하여 향후 공사의 전망 등을 예측할 수 있어야 하는데 이에 대한 연구가 필요하다.

Different from traditional development methodologies like waterfall model, the CBD (component based development) methodology relies on a building block approach in the design and development of information system. The audit procedure and checklist for the traditional IS development methodology are required to be modified to be suitable for CBD. This research reviewed IS audit guidelines for the existing development process and analyzed multiple projects that employed the by component based development process. For the purpose of this study, we chose a governmental project and a next-generation IS project of a financial agency as sample cases. By comparing existing IS audit checklists and items actually reviewed in audit projects, this study identified appropriate check items for the CBD-centric audit program. New items were proposed as additional items such as project control in management phase, usage case and conceptual model establishment, component evaluation and design, in implementation phase, and so forth. The result of the research provides new guidelines for the audit CBD projects for the purposed of increased efficiency and qualify of application development projects.
