The cooperation and trust among the project participants play a critical role in the success or failure of any delivery system in construction industry. But it is very difficult to establish trust between an owner and a contractor when rational people only pursue only their own material self-interest. Based on the principal-agent theory, this paper will introduce the altruistic behavior into the traditional principal-agent model, and model the reciprocal behavior between the owner and contractor. We will show that both the owner and the contractor benefit from their reciprocal behavior, and hence trust establishing between them is possible. More importantly, we will proof that the higher the project uncertainty is, the more important trust establishing is.

Purpose: Children in migrant villages in Kyrgyzstan have a high incidence of anemia and need effective health promotion programs. The purpose of this study was to evaluate a pilot study of a health promotion project for infants and toddlers based on community participation. Methods: This was a retrospective study conducted to evaluate the effectiveness of the project. The project was carried out by nurses at a public health center, community health workers, and local residents in a migrant village. After the operational system of the project was established, health assessments, child-care education, provision of vouchers for iron supplements, and activities to improve residents' awareness were conducted during 6 months among 100 children, of whom 85 were finally analyzed. Results: In international health projects, close cooperation of the project team with community residents and health workers is important. Access to the community-based program was feasible in the socially and economically poor migrant village, and improvements were shown in children's anemia and awareness of health care. Conclusion: By focusing on the effective aspects of this preliminary project, plans to utilize community health workers and promotion strategies can be added to the main project to improve health promotion among children in this area.

공사비의 정확한 예측은 프로젝트 성공의 핵심 요소이다. 그러나 도면, 시방서, 공사비 산출내역서 등이 아직 불완전한 기획단계의 경우 신속하고 정확하게 공사비를 산출하기가 용이하지 않다. 또한 프로젝트의 기획단계에서 정확한 공사비 예측은 프로젝트의 타당성 조사 및 성공적인 완료에 중요하다. 따라서 프로젝트 정보가 제한적 일 때 사업 초기에 공사비를 정확하게 예측하기 위해 다양한 기법(회귀분석, 인공신경망, 사례기반추론, 유전자알고리즘, 몬테카를로시뮬레이션, 빌딩정보모델링)이 적용되고 있다. 공사비 예측에 영향을 미치는 많은 요소가 있다. 본 논문에서는 7개(대지면적, 연면적, 지하층수, 지상층수, 주동수, 전체세대수, 공사기간)의 건축개요를 독립변수로 사용하는 다중회귀모델(후진제거법)로 공사비 예측치를 제시한다. 다중회귀모델을 이용한 지역주택조합사업 공사비의 예측 결과 오차율은 4.87%로 나타났다. 이는 지역주택조합사업의 기획단계에서 공사비 예측에 관한 연구가 없어 비교가 불가능하나, 기존에 사용하던 단위면적에 대한 단가산정방식에 비하여 높은 예측 정확도를 가짐으로써, 향후 지역주택조합사업의 기획단계에서 공사비 산출업무에 적용 가능성이 높고, 지역주택조합사업의 사업예산 수립에 기여할 수 있을 것으로 판단된다.

Military aircraft R&D projects require large-scale investment in cost and time, and involve a complex coordination process in decision-making. The R&D project manager should determine the development management priorities as accurately as possible and focus on R&D capabilities, thereby reducing the risks of the aircraft R&D project. To this end, this study aims to reduce R&D risk by prioritizing cost, schedule, and performance, which are basic management factors used in R&D project management in defense project management regulations. Analytic Hierarchy Process (AHP) is applied using a questionnaire for managers in charge of aviation R&D under the Defense Acquisition Program Administration. As a primary result, the importance of the factors that the aircraft R&D project manager should consider was derived in the order of performance, cost, and schedule, and the priorities of performance and cost in the lower layer were also identified. In addition, in order to provide practical risk management measures to aircraft R&D project managers, the results of analyzing 28 cases of US National Transportation Safety Board accidents were compared and analyzed with the AHP analysis results, and management measures suitable for the situation were specified.

A construction project is a designed product made up of labors, materials, and installations in the project positioned on the ground and may include the underground and ground section, and the section in water or on the water surface. It is a civil, industrial, transport, agricultural and rural development, infrastructure, or some other. A key phase in the life cycle of these construction projects is the implementation when building products are made directly with workers, equipment, materials, and managers. If there is a lack of management experience, information, and problem-solving solutions to tackle the risks faced by contractors, especially foreign ones, will fail in controlling the project's cost. This study was conducted with investigations, discussions, and evaluation of the factors that lead to cost overruns in the construction projects of international contractors in Vietnam. The principal component analysis (PCA) showed that those factors that influence cost overruns these construction projects fall into five general groups, including factors related to (i) the owners, (ii) the foreign contractors, (iii) the subcontractors and suppliers, (iv) state management, and (v) the project itself. Besides, the study proposes solutions to limit cost overruns in construction projects and improve the profitability of international contractors in Vietnam.

The purpose of this study is to develop a teaching-learning model of convergence project based on team teaching. Based on development research methodology which explored a university case, the teaching-learning model was developed including three phases such as preparation, planning, and implementation & evaluation. The preparation phase has three steps as follows: to organize team teaching faculty; to develop convergence projects cooperated by industry and university; and to design instructions based on supporting convergence projects. The last step of preparation phase consists of five design activities of: (1) instructions and teaching contents; (2) communication channel among faculty members; (3) feedback system on students' performance; (4) tools to support learners' activity; and (5) evaluation system. The planning phase has two steps to analyze learners and to introduce and modify instruction and themes of convergence projects. The implementation & evaluation phase includes five steps as bellow: (1) to organize project teams and match teams with faculty members; (2) to do team building and assign duties to students of a team; (3) to provide instruction and consulting to teams; (4) to help teams to conduct projects through creative problem solving; and (5) to design mid-term/final presentation and evaluation. Lastly, the research implications and limitations were discussed for future studies.

This paper summarizes some of approaches that could be taken for data exchange in a non-interoperable work environment and reports lessons learned from the Dongdaemun Design Plaza and Park project. Today's widespread application of building information modeling (BIM) to the construction and architectural design industries requires a change in the cooperation between business organizations and their methods of communication. In particular, the interoperability of information between interdisciplinary organizations, which use specific programs for different purposes, has become a critical issue. More than just a technical problem, it is also highly related to an organization's collaboration culture and the particulars of a specific project. This paper describes the interoperability issue that occurred during the construction documentation phase of the irregularly shaped building project, Dongdaemun Design Plaza and Park, designed by Zaha Hadid Architects and Samoo Architects and Engineers, from the perspective of the technological problem and the collaborative organizations' communications. Although the perfect compatibility of information is not possible, this paper deals with a practical approach to the interoperability issue by examining the way the end-users of computer-aided design (CAD) resolved the interoperability problems in practice.
