건설공사의 계약문서에는 설계도면, 공사시방서 등이 포함되나, 국제적인 수준의 계약문서로서 다소 미흡하게 작성되었던 것이 사실이다. 이러한 문제점을 해결하기 위하여 '98년 1월부터는 설계도서 작성시 공사시방서를 작성하도록 하였다. 그러나 제도의 도입초기이므로 참고할 만한 자료도 충분하지 않으며, 작성경험 및 능력도 부족한 실정이다. 이러한 점을 보완하기 위하여 개발된 기존 시스템은 네트워크를 고려하지 않아 시스템 활용과 유지관리 및 갱신에 한계가 있다. 본 연구에서는 기존 시스템을 개선하여, 전문시방서, 설계기준, 하위기술기준 둥 건설공사기준 DB를 구축하고, Web을 통해 구축된 DB를 검색·활용하여 공사시방서를 실시간으로 작성하는 시스템 개발 방안을 제시하였다. 이러한 시스템은 공사시방서 작성시, 표준시방서, 전문시방서 등 다양한 정보를 조회하여 수준높은 공사시방서를 작성하는데 일조할 것으로 기대된다.

최근 역량중심교육이 강조되면서, 교육 현장에서 프로젝트수업이 활발하게 행해지고 있다. 본 연구에서는 프로젝트를 기반으로 한 수업의 운영체계를 개발하는 연구를 진행하였다. 첫째, 모듈(교과목)과 연계하지 않고, 독립적인 프로젝트를 운영하는 방법, 둘째, 하나의 프로젝트에 단일 전공(학부) 내 모듈을 연계하여 운영하는 방법, 셋째, 하나의 프로젝트에 2개 이상의 전공 모듈을 연계하여 운영하는 방법을 제안하였다. 또한 프로젝트수업을 위한 도구를 제시하였다. 프로젝트 수업의 체계적 관리 및 개선을 통한 수업만족도 제고를 위해 프로젝트수업의 사전, 사후검사를 실시한 결과 프로젝트 수업은 창의적 인성과 문제해결 능력의 향상에 긍정적 효과가 있는 것으로 나타났다. 또한 수업에 대한 만족도가 1차 년도 대비 2차 년도에 7%향상되었다. 이에 따라 학생들의 학습 성과 달성률이 높아졌다는 평가가 도출되었다.

The Light Rail Transit Project is a large scaled project which takes several years in building a system. After construction, LRT system is operating for several tens of years. For these characteristics, the right application of systems engineering to LRT project greatly effects the project success. In this paper, we present systems engineering application model to LRT project i.e. SELRT which include systems engineering technical process, core technology management process, project support process. SELRT also has a module for the exchange of outputs in SE tool and PM tool. Systems engineering processes in SELRT mainly base on ISO/IEC 15288. In future, we expand the range of SE processes and improve the usability in SELRT. We expect that this model will contribute to improve the efficiency in LRT project and to success the LRT project.

RIMS（Rolling Stock Information Maintenance System)　was installed in structure which it can analyze the data base in need of credibility maintenance. So it could accumulate real data without repulsion of working spot. Information system was installed not following to system but following to working spot. The development of RIMS project was started from March 29, 2001 and it has been operating from October 12, 2004 in Chang-dong Car depot for light maintenance in charge subway line4. So substantial data base was accumulated for three years. This study calculated all RAMS data by analyzing data base accumulated in RIMS and used in dada base about credibility maintenance and found investigation of propriety, expectation of the life cycle cost, the improvement plan on credibility of sorts of cars and formation about the cycle of repairing and maintenance. This got MKBSF MKBF and MTBF about devices and sorts of line4 Rolling Stocks for it.

In this study, we have analyzed the cost of korea high-speed railway system. The predicted cost in planning phase and adjustment data to 5th year are collected. Then, predicted cost is compared with adjustment in year/item/system base. We make a project history table for criteria to review project history and research & development activity. We have developed CBS(cost breakdown structure) and allocated adjustment data to them. It is shown that cost prediction related to research & development activity in planning phase is relatively correct.

Virtual reality (VR) technology for construction project includes 3D CAD application and 4D CAD system for visualizing construction schedule data. 3D CAD application is more important in the design phase and 4D CAD system is effective tool in the construction phase. This study suggests a methodology to develop VR functions that can be used for project life cycle. The results of this study includes composition algorithms to make VR systems such as bird's eye view system, VR drawings system, VR telepresence system and VR risk management system. Those methodologies can be used for integrated VR system with nD CAD object.

The Army, Navy, and Air Force are currently making various efforts to apply defense IoT technology by reflecting the characteristics of each military. However, there are concerns that comprehensive collection, management, and analysis may be limited because each military has no overlapping system or guaranteed interoperability of data, and there are inefficient aspects in terms of using and investing a limited defense budget. In this study, evaluation items and priorities for pilot projects were selected by applying Delphi technique and AHP method to determine which projects are preferentially effective when commonly applied in terms of Army, Navy, and Air force. As a result of the analysis, the project basis and driving force, project feasibility, performance and ripple effect, redundancy and connection were identified in the order of IoT-based small detachment units and unmanned base construction, intelligent smart unit, smart ground ammunition depot, and smart training management system. According to the comprehensive results reflecting the weights of each evaluation item, the fact that small detachment units and unmanned base construction project are recognized as the first project to be applied to the Army, Navy, and Air Force is a valid approach to be effective while each military is burdened with personnel management because of the reduction of manpower. Through the research results, it is expected that the direction of application to the policy of the defense IoT project can be confirmed in terms of efficient use of limited budgets.

The widespread introduction of unmanned aircrafts has led to the understanding of the need to organize a common information space for manned and unmanned aircrafts, which is reflected in the Russian Unmanned aircraft system Traffic Management (RUTM) project. The present article deals with the issues of spatial information database (DB) organization, which is the core of RUTM and provides storage of various data types (spatial, aeronautical, topographical, meteorological, vector, etc.) required for flight safety management. Based on the analysis of functional capabilities and types of work which it needs to ensure, the architecture of spatial information DB, including the base of source information, base of display settings, base of vector objects, base of tile packages and also a number of special software packages was proposed. The issues of organization of these DB, types and formats of data and ways of their display are considered in detail. Based on the analysis it was concluded that the optimal construction of the spatial DB for RUTM system requires a combination of different model variants and ways of organizing data structures.
