Currently, the construction industry in Korea implements the risk assessment that is implemented by managers and working team leaders. However, it is difficult to share the result of risk assessment meeting to substructural workers in korea system and the workers don't understand meaning and effect about risk assessment. The risk assessment is that the workers in the construction site have to know risk factors and reducing ways to the risks. But, the education and sharing methods for risk assessment system is insufficient in korea. For this risk assessment problems identified were surveyed. In order to improve the problems of the risk assessment, proposes the following three methods. First, Implement to educate the risk assessment during the basic safety and health training of construction industry. Second, the training way about workers' participation in risk assessment is necessary. For example, after watching videos, etc, the workers create risk assessment in person and make a presentation about it. Third, the risk assessment utilize during TBM(Tool Box Meeting). Before working every day, we need to educate risk factors and the reducing ways to the risk during TBM.
This paper introduces the Hierarchical Decomposition Mapping Diagram (HDMD) that represents the systematic architecture of axiomatic design. HDMD is composed of the contents of module symbol and the independence/dependence relationship between FRs (Functional Requirements) and DPs (Design Parameters). The examples presented in this paper show the strength of the diagrams in comparison with other studies of systematic architectural representation tools, such as hierarchical diagram, module-junction diagram and system flow diagram.
