본 논문은 도로 건설 공사 프로젝트들의 전 공정에 걸쳐 수행되는 모든 작업들을 대상으로 총 프로젝트 생산성 (Total Project Productivity)을 측정하고 분석하기 위한 방법을 소개한다. 측정 방법의 주안점은 복합적으로 병행되는 작업들의 생산량을 통합하여, 프로젝트 전체에 대한 포괄적인 생산성 값들을 구하는 방법을 개발하는데 두고 있다. 이 방법을 통해 Florida Department of Transportation (FDOT)로부터 발주된 세 개의 실제 고속도로 건설 공사 프로젝트들로부터 수천 개의 총 프로젝트 생산성 데이터 값들이 얻어졌으며. 이를 바탕으로 프로젝트 생산성을 분석하기 위한 방법의 타당성 검증이 이루어졌다. 그 결과로, 프로젝트 레벨에서의 총 생산성은 건설 작업들에 관한 현장 자료를 바탕으로 측정과 분석이 이루어질 수 있음이 입증되었다.

The purpose of this study is establishing effective multimodal logistics structure in northeast Asia. For this end, the interface between transport modes, construction method of rail-ferry transport system, system operation and implementation strategies by step were studied. Rail-ferry system have a competition over present transportation system in international cargo trade market between Korea and China. And, the operation of rail-ferry transportation system between Korea and China is meaningful project in the point of providing various choices to clients. Korea and China should have agreements in trade, customs duties, ports in the next year for the success of this project.

This paper addresses the outlines of the traffic signal timing principles engaged in TRACS and the results of field test. Research team, encompassing research institute, university, and electronic company, conducted the three-year project for developing the new system, named TRACS(Traffic Adaptive Control System). The project was successfully completed in 1994. TRACS aims at accomplishing the objectives of better traffic adaptability and more reliable travel time prediction. TRACS operates in real-time adjusting signal timings throughout the system in response to variations in traffic demand and system capacity. The purpose of TRACS is to control traffic on an area basis rather than on an isolated intersection basis. An other purpose of TRACS is to provide real-time road traffic information such as volume, speed, delay , travel time, and so on. The performance of the first version of TRACS was compared to the conventional TOD control through field test. The test result was promi ing in that TRACS consistantly outperformed the conventional control method. The change of signaltiming reacted timely to the variation of traffic demand. Extensive operational test of TRACS will be conducted this year, and some functions will be enhanced.

Now, the goal of the third generation KTX project is to create a new species of high speed train in order to open a new era of high speed railway system in history by authentic Korean technology and innovative design. Now the third generation KTX, must go beyond the original stagnant paradigm and be positioned as an emotional resource which is creating a shift in the public's perspective of transportation and expanding the idea that transportation intersects the two distinct realms of culture and environment as well. In addition, the overall design should reflect the Korean culture and characteristics, simple yet resonant, both the interior space and the exterior fuselage should portray the dynamic heritage of Korea such as the powerful yet subdued energy of Jung Joong Dong. In short, through the symbolic key words in Korean, Dong(Dynamics), Mek(Pulse), Ryu(Flow), Gam(Sensibility), the third generation KTX design project aims to create an new identity of Korean high speed railway which can stand globally.

지방도로의 포장 및 확장사업으로 인한 지역개발효과를 분석하였다. 효과발생시 시기적 특성을 기준으로 할 때, 도로개선사업의 지역개발효과는 직접효과, 유발효과 및 간접효과 등 세가지의 유형으로 구분될 수 있다. 이들 각 유형의 효과가 각각 어떻게 발생되는가를 파악하기 위하여 본연구에서는 교통부문, 농업부문, 공업부문, 공공 서비스 부문, 주거부문 및 인문사회부문 등 6개부문에 대한 도로개선 사업의 효과를 분석하였다. 분석은 ADB 5차사업으로서 1983년에 공사를 시작하여 1985년에 사업이 완료된 밀양 및 하동지구를 그 대상으로 하였다. 도로개선사업의 효과가 사업종료 후 어느 시점에서부터 발생되는가를 관찰하기 위하여 효과분석을 위한 자료수집의 시점을 사업전 (1983년), 사업완료 직후(1986년) 그리고 사업완료 5년후(1992) 등 크게 세가지로 구분하였다. 1983년 및 1986년의 자료로는 건설부에서 조사한 자료들을 이용하였으며, 1992년의 자료는 현장조사와 해당군의 통계에서 수집된 자료를 이용하였다. 도로사업으로 인한 순효과를 측정하기 위하여 본 연구에서는 각 대상지역을 사업지구(Project Area)와 대조지구(Control Area) 로 구분하고 이들 각 지구에 대한 시점별 분석들 실시하였다.

The mission of tilting train development project is enhancing the speed of transportation of railway passenger using existing infrastructure. The threat of this project is the tilting technology is newly incorporated to this project. To overcome the threat this project incorporate systems engineering technology to development tilting train system. The systems engineering process, which was used in this project, was performed in accordance with systems engineering standard EIA632. This paper shows the systems engineering technology which was used to develop the tilting train system specification. This paper also shows the requirement template which was developed to communicate and synthesis various specialty engineering.

In this study, our purpose is to identify a causal relationship in consciousness relating to the public involvement for current road improvement projects in Seoul Some of hypotheses about causal relationships among the psychological factors are assumed to develop a structural equation model. This model includes latent variables determining the consciousness relating to public involvement procedure, such as distrust feeling for administration (public sector) the knowledge and satisfaction about the road project, and the comprehensive faculty on the public involvement. The estimated model indicates that these assumed hypotheses are proved and that the administrative distrust strongly determines the consciousness as well as understanding of the road project and the knowledge of PI procedure.

The scope of this study is the construction conformity assessment system according to the new paradigm of construction management To minimize the differences between domestic and international state, construction Conformity Assessment is subdivided into system certification and product certification. For the former, WASCON(Worldwide Assessment System of Construction Quality Maturity Stage) is applied. For the latter, AQUA(Advanced Quality Assessment System) was developed and adopted to model project for demonstration. Both systems are designed to enable quantified rating, integrated into PQCS(Project Quality Certification), which is an advanced project quality certification system. The construction work observing PQCS will gain quality score on its own quality certificate(Quality mark on construction itself or facilities is also available, if needed or preferred by customers). This Quality Rating System will inspire and encourage any related parties. PQCS score would let supplier/constructor recognize how much themselves are operating effectively and efficiently, offering them the opportunity of redeeming their weaknesses.
