This study highlights empirically the relationship among major constructs such as accident, fear and anxiety emotion, self-efficacy, and negative spillover of work, focused on the railway drivers. The differentiated factor of this study is in that the experience of accident was posed as exogenous variable. Hypothesis tests based on 201 samples verified that the experience of accidents showed a significant effect on negative spillover of work mediated by fear and anxiety, with moderating effect of self-efficacy between fear and anxiety and negative spillover of work. However, the moderating effect was shown as increasing the degree of negative spillover of work, since the drivers recognized their fear and anxiety accrued by accident experience as uncontrollable. This finding suggests the need for mitigating driver's negative emotion - fear and anxiety - through an introduction of practice such as exemption of settlement obligation in accident site and lowering of the penalty for accident responsibility.
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.
As the whole society grows insensible to its own safety, we keep having continuous big fires such as "Deagu Subway Arson Attack" and "The fire at a football training camp in Cheonan Elementary School." However, we fail to have at least a guidbook which contains minimal information regarding how to prevent big fires or arson attacks, moreover there isn't any educational system that allows the public to have a good habit for their safety. As for developed countries right after industrialization, the education on fire prevention and safety became mandatory for all schools and became one of their required school curriculum. If this becomes the case in Korea, Korea will be able to reduce the potential casualties in case of big fires and emergencies. Therefore, in this research, we would like to establish some appropriate measures and standards for fire prevention and safety based upon the current and immature situations in Korea.
