Recent Construction and Transportation R&D projects are larger in size, investment scale has been increasing rapidly. However, the results of Construction and Transportation in R & D are papers, patents and other results. So, the application record of R&D in the construction field is very lacking. In particular, Construction New Technology's ratio in the midst of R&D's results are about 2.29%. Therefore, this study suggested program that R&D's results has been connected Construction New Technology. The introduction of the new system has greatly increased Construction New Technology and the results of excellent &D will be applied in construction field. So, Cost-reduction and technology's improvement are expected.

건설 프로그램 수준의 복합용도개발사업은 다양한 참여주체들에 의해 장기간에 걸쳐 대규모로 추진되는 사업특성으로 인하여, 사업기간동안 여러가지 갈등이 발생하게 된다. 특히 다양한 프로젝트가 복합된 프로그램 사업의 특성상 참여주체별 요구사항이 상이하여 시설종류 및 규모를 적정하게 계획하는 것이 매우 중요하며, 이를 위해서는 사업의 기획단계에서부터 VE를 실시하여 고객의 요구에 적합한 해결책을 도출할 필요성이 있다. 따라서 본 연구에서는 건설 프로그램 사업의 기획단계 VE 수행에 있어서 발주자의 요구사항을 명확하게 파악하여, 해당 프로그램에 요구되는 적정시설을 제시하기 위한 다차원 품질모델을 개발하였다. 다차원 품질모델 개발을 통해 복합용도개발사업의 12개 성능지표별 15개 주요시설의 특성분포를 제시하였으며, 참여자 요구사항에 따른 적정시설 도출 및 검토, 성능지표간 다차원 합성방안을 제시하였다. 본 연구는 건설프로그램 사업에 기획단계 VE를 적용하기 위한 기본연구로서 의의가 있으며, 본 연구에서 제시한 다차원 품질모델을 통하여 사업초기단계에서 다양한 참여주체들의 요구사항을 기반으로 적정시설을 제시 또는 검토하는 것이 가능할 것으로 기대한다.

매스콘크리트 시공시 콘크리트의온도가 급격히 변화하면 콘크리트에는 균열이 발생하게 된다. 매스콘크리트를 타설한 후에는 구조물의 주변환경조건이 콘크리트의 온도를 변화시키게 된다. 그러나 아직도 주변환경조건을 고려하여 콘크리트의 온도이력을 엄밀하게 해석할 수 있는 해석기법이 개발되지 않은 상황이다. 본 연구에서는 대기온도, 양생온도, 거푸집재료, 거푸집의 존치 및 제거, 추가양생 등 주변환경조건이 매스콘크리트 온도이력에 미치는 영향을 정량적으로 해석하기 위하여 유한요소정식와에 열전달계수, 주변환경조건 및 거푸집조건을 도입하였고 이를 해석할 수 있는 알고리즘과 해석프로그램을 개발하였다. 본 연구의 수치모형 해석값을 모형실험값, 타연구 모형실험값 및 기존의 범용프로그램에 의한 해석값과 비교한 결과로부터 본 연구의 온도해석이론의 타당성 및 정확도를 분석하였다.

This study examined the effect of safety leadership coaching program on managers' safety management and workers' safety behaviors in construction site. Three or four managers and about one hundred workers at each site participated in this study. Safety leadership coaching program consisted of safety leadership education, goal setting, self-monitoring and feedback on workers' safety behavior, reward for three safety management behaviors; (1) safety observations of workers safety behavior and (2) providing positive feedback on safe behavior (3) providing corrective feedback on risk behavior and daily safety education for workers. Dependent variables were the percentage of safe behaviors of workers and frequency of managers' safety management behaviors. A nonconcurrent AB multiple baseline design across settings was adopted. After baseline(A), safety leadership coaching program (B) was introduced to each site. The results showed that safety leadership coaching program was effective to increase managers' and workers' safety behaviors. These results suggest that safety leadership coaching program developed in this study would be an alternative treatment technique to improve construction safety management. In addition, the implications, limitations of this study, and future studies are discussed.

In this study, Site Investigation Program of cut slope is developed using related techniques and experience got from practical application of Inventory Survey Program of cut slope in work for last 4 years. The Site Investigation Program is designed to can be loaded to the Mobile PC for convenience of carrying in filed, convenience of data input and revision, application of diverse programs, convenience of confirming data and facility of establishment of real-time database system using wireless communication like Inventory Survey Program. Also, for connection with Inventory Survey Program, it has a same work process and can establish real-time database system of almost data obtained in filed using stability analysis tool loaded in this program. Application of this developed program is expected to be an opportunity that can contribute to development of slope investigation and database system area using IT techniques.

In past projects, the main goal has been to enhance efficiency by reducing cost and time. However, considering the current condition of safety management in many construction companies, it can be confirmed that safety management has not been a top priority for a long time. Current safety management, which is based on safety standards and rules, is very ineffective and only emphasizes management after an incident. As well, although fewer accidents occur compared to the past, because construction projects are increasingly large in scale and complex, these accidents tend to be more serious and involve greater monetary loss. Furthermore, as the severity of these accidents increases, so does the possibility of fatalities. Therefore, improving safety management is essential. This study proposes an effective program for safety management, focusing on the processes to connect studies and systems, and the basic techniques required for program development. To realize this program, technical tools are suggested, including systems such as BIM (Building Information Modeling); additionally, the coordination of other systems such as an RTLS, a server, and an alarm system is proposed.

Bromilow's time-cost (BTC) relationship was examined for building projects in Vietnam using actual construction time and total construction cost. Data set was collected from 77 historical building construction projects completed between 1999 and 2005 which were adjusted by consumer price index (CPI) to 2000 price. Time-cost equations were specified respected to two sectors, public and private, in Vietnamese construction industry and all cases. It is shown that a public funded building project has the longer construction duration than a similar budget private funded project. The resulting models are statistically significant. The adjusted R-square coefficients of all cases, public and private projects models are respectively 0.403, 0.436 and 0.377 mean that the BTC regression lines moderately fit the data set.

As RC structures in the marine environment rapidly increase, the interest and the importance of Chloride Penetration durable design have been growing. However, there is hardly any domestic Chloride Penetration durability of RC structures designed analysis programs. Currently, Chloride Penetration durable design method is studied and launched actively as a program in the United States, Europe, Japan and etc., but it is limited to Chloride Penetration durability of RC structures excluded from maintenance construction. Also, the level of dependence on the foreign technology is high; the foreign program is imported and used when needed. The main objective is to compare and to evaluate with the durability assessment program and several conditions when considering the design of Chloride Penetration durability through the programs developed abroad.
