  • Recently, many companies recognize the individual human resource as a core asset of the corporate value creation and devote a lot of effort to develop and manage competency-based human resource in order to strengthen the corporate competitiveness. As the integrated construction company taking the major portion in Korean construction industry, its construction engineers perform the construction supervision task with various related parties at each stage of the life cycle of the construction project. Therefore, the competency of a construction engineer is an important factor which have a direct impact on the success of the construction project. However, the current capability evaluation scheme of the domestic construction engineers is mainly oriented on the qualification factors such as the certificates or the seniority and this is quite different from evaluating the actual ability for construction management tasks. In this point of view, this study proposes the appropriate level of proficiency in cost management by analyzing the work process and its detailed items of the cost management that is the one of the basic management items of the construction industry. Based on this, this study analyzes the current competency level of the construction engineer by comparing with the required competency of each job position and also performs the engineer's work competency analysis of each work step.

  • As construction project has been becoming larger, specialized and complicated, it is important to utilize a lot of information that is made by diverse participants. Especially this information is mainly produced in construction site that plays a leading role in construction project. The problem of information exchange between participants of construction site causes decline of construction productivity. So as to resolve this problem, there is a many interest in BIM(Building Information Modeling) that makes and manages a necessary data during building life cycle. But in Korea construction industry, applying BIM in construction phase is less active than in design phase. Through studying previous research, this study classify the main cause of failure related to information exchange in framework construction. And by interviewing expert, it draw a work that is possible to apply BIM. Next through analyzing framework construction site that is applied with BIM, this study proposes specific information flow model for supporting work by BIM.

  • Recently, each country has been trying to promote Eco-Industrial Park (EIP) development for industrial sustainability. Technological modeling is required to realize EIP practically even though the project contains the political concerns for many companies, government, and self-governing bodies. The four main technologies of the EIP developments include energy exchange, material flow analysis, water pinch, and life cycle assessment. Material flow analysis (MFA) methodology can be utilized in EIP modeling in view of the fact that the analysis of material flows and the optimized modeling are major purposes for the technological modeling of EIP. Through MFA methodology in POHANG EIP project, how to apply MFA modeling to EIP modeling and how to utilize software for MFA modeling are shown in this research.

  • This purpose of this study was to explore the implication of the social work practice through the experiences of the users who participated in the crisis support program. To do this, In-depth interviews were carried out with 12 research participants. The data was analyzed by general qualitative research methods. As a result of analysis, prior to participating in the Triangle Project, users lost their will to live in a vicious cycle of life crisis. Through the participation of the service, they were able to receive the integrated support of 'pregnancy - childbirth - rearing'. These experiences ultimately led to the regeneration of the will to live. Based on the results of this study, we suggest practical and policy implications that can complement the limitation of Korean unwed mothers' support system.
