When developers conduct a systems engineering approach the first problems that they will be faced are how to define and analyze the operational concept. In case of practical use project of MAGLEV train, those problems are also important since end products of practical use project must be assured for commercial service level. Lack of domestic developer's experience on systems engineering activity can cause a confusion a progress of the project. This study will propose a guide to establish an operational concept of project to develop or construct urban transit system.

Proto-type Korean High Speed Train(HSR 350x) had developed in 2002 through G7 High Speed Train R&D project from 1996, had carried successful trial running test up to 350km/h and has been executing running test more than 0.2 Mil. kilometers of accumulated running distance to insure reliability on service line till July 2008. Even though the R&D project has finished by Oct. 2007, the proto-type train HSR 350x has maintaining various measuring functions and test facilities till now. So it may be needed a suggestion on the direction of practical use in public purpose of the HSR 350x. This study has suggested several directions of practical use in public purpose of the HSR 350x, and feasibilities for each alternatives of practical use in order to contribute making reasonable decision for practical use of the train in public purpose for the future.

Making practical use of urban MAGLEV system which is tried by government includes technique development and railway construction. Because huge amount of money will be spent on this project, feasibility study is being carried out in order to check the feasibility and to devise the master plan in prior to making practical use of urban MAGLEV system. The key issues of feasibility study are possibility of technique development, economical feasibility, location of a model railway and the improvement of related laws and regulations. This paper shows the approach to solve these key issues.

Computer simulation is widely known as a very powerful and practical tool to understand behaviors of considered systems and evaluate design alternatives. However, to use simulation technologies, one should acquire simulation languages, statistics, etc. Also, lots of resources such as time and money are necessary to develop models and analyze statistical data. These obstacles prevent one from adopting simulation tools easily. This paper presents practical guidelines for successful application of simulation. Firstly, we propose how to acquire simulation tools to help one who is going to use simulation techniques. Next guidelines are for introducing simulation software set including simulation and support softwares. Lastly, guidelines for simulation project management are presented.

The major countries including Korea extend the national investment on R&D and implement the business performance diffusion policy as the knowledge based competition age arrives recently. The necessity for risk management and systematic management system for R&D achievement have been appeared to prevent the failure as the R&D scale becomes larger as it was said. For this matter, the organization such as NASA and DoD in USA defines the Technology Readiness Level (TRL) as a quantitative accomplishment management index and utilize the Technology Readiness Assessment (TRA) system as a criterion. Such tool is evaluated as very effective in the R&D project purposed the practicalization. It is expected that the disadvantage of evaluation system which is oriented to the academic accomplishment in its contents of current research and to contribute greatly to the practicalization of outcomes when such technology readiness level concept is applied to Korean national construction and transportation R&D project. Accordingly, this study analyzed the concept of TRL·TRA, the characteristics and current evaluation management system of Korean national construction and transportation R&D project and suggested the construction and transportation R&D project TRL·TRA performance model to accomplish the practicalization purpose.

BIM is a practical and economical technology used in the construction process. Despite the fact that BIM is widely used in the design and another stage before construction, it is not largely applied during the construction stage itself. However, it is important to opt for BIM during construction stage because there may occur a number of risks such as construction delay and increased construction costs. Therefore, the present paper contains the analysis of the model use, which is mainly applied to respond to the BMI RFI that represents an information requirement of construction site workers, by analysing the BMI RFI application at the construction site. In addition, there is an analysis of the way the derived model use affects the project goal aimed at the project success.

Considering the risk management, there are many examples and various studies for the corporation risk. However, I have never seen the project risk management that applied a construction site for practical approach. Therefore, I have developed a chart (I-Chart) for the project risk management, and also built a model (I-Chart scenario analysis) that I could use. I applied this model to container yard reclaimed land in harbor construction with approaching of geotechnical engineering.

최근 지식기반 경쟁시대가 도래함에 따라, 우리나라를 포함한 주요 선진국은 R&D 투자를 확대하고, R&D사업의 성과확산 정책을 추진하고 있다. 이를 위해 미국의 NASA, DoD 등의 기관은 정량화된 성관관리 지표로서, 기술성숙도(TRL)를 정의하고, 이를 기준으로 판단하는 기술성숙도 평가체계(TRA)를 도입하여 활용하고 있으며, 이러한 도구는 특히 실용화를 목적으로 하는 R&D사업에 매우 효과적인 것으로 평가되고 있다. 이와 같은 개념은 실용화를 목적으로 하는 국내 국가 건설교통 R&D사업에 적용했을 때, 현재 연구내용의 학술적 성과에 치중되어있는 평가체계의 단점을 극복하고 실용화 달성의 취지를 크게 개선할 수 있을 것으로 기대되며, 따라서 본 연구에서는 TRL 및 TRA 개념과 국내 국가 건설교통 R&D사업의 특성 및 현행 평가 관리체계를 분석하여 실용화 목적 달성을 위한 건설교통 R&D 사업의 TRL TRA 수행 모델을 제시하였다.

Because 6sigma is doing innovative success In management whole, estimate that can exert direct effect in interior Design management. Therefore, this study did by purpose that 6sigma that is scientific method that do customers satisfaction by ultimate purpose acts as basic study that can heighten practical use Possibility and result of interior Design management and value by interior design standardization process. Need to use marketing data that is scientific design component at schematic design step for successful interior design that can improve result. Hereupon, this study is doing to big dimension that utilizes 6sigma and makes standard process of only Interior Design, and did to dimension that present study phase verifies if '6sigma' is practical use possibility by intoner design process. Did by method that verification method of 6sigma practical use possibility analyzes "Information transmission efficiency improvement of department store display space" 6sigma project example. When see that example project is analyzed on Improvement constituent that "Design improvement" out of Vital few Xs of statistical analysis item must heighten the customers satisfaction rate conclusively, target process might be established because design becomes center of gravity if did design improvement very first time. Finally, possibility that 6sigma can utilize in process of interior design is verified, and it is scientific methodology that can utilize to all business members that there are not any special category of business even if is in practical use. Such scientific 6sigma method need persistent study that make standard process analyzing a lot of problems that is expected to be beaconed and happens substantially in here after to management development of interior design.

최근 팀 프로젝트에서 모바일 커뮤니케이션 서비스(MCS: mobile communication services)를 활용한 협업이 활발히 진행되고 있다. 본 연구에서는 MCS를 활용한 협업이 팀 프로젝트 성과에 미치는 영향을 살펴보았다. 조직 측면에서 팀 몰입과 팀 신뢰가 팀 프로젝트 성과 형성에 핵심적인 역할을 담당할 것으로 예상하였으며, MCS 유용성의 영향에 대해서도 살펴보았다. MCS 유용성을 형성하는 주요 특성으로 유비쿼티, 복합적 사용, 사용 용이성을 고려하였다. 팀 프로젝트 수행 시 IT 서비스를 자주 활용하는 116명의 대학생들을 대상으로 연구 모형을 검증하였으며, PLS를 활용하였다. 연구 모형 분석 결과, 팀 신뢰는 팀 몰입과 팀 프로젝트 성과에 긍정적으로 유의한 영향을 미쳤다. 하지만, MCS 유용성은 팀 몰입에 유의한 영향을 미치지 않았고, 팀 프로젝트 성과에만 유의한 영향을 미쳤다. MCS 특성 가운데 사용 용이성만 MCS 유용성 형성에 도움을 주는 것으로 밝혀졌으며, 유비퀴티와 복합 사용성은 MCS 유용성에 유의한 영향을 미치지 않았다.
