| Abstract |
Construction industry is becoming more advanced, but safety accidents are not decreasing and unsafe act (UA) and human errors (HE) are
the main causes of safety accidents. Therefore, this study aims to analyze the relationships between unsafe acts and human errors for
construction accident prevents. Specifically, the Correlation Analysis is used to quantify 24 combinations of the relationship between the UA
and HE. Then, the Kano Model, and Timko Satisfied Coefficient was utilized to find 6 combinations for construction accident prevention
plans. As the result of Timko Satisfied Coefficient, an interview was conducted with three safety managers and 6 safety prevention plan is
proposed. Through these results, it is expected that the combination of 24 accidents will be basic data of safety management. Especially,
the proposed safety prevention plans considering the characteristics of 6 combinations with high correlation can contribute to prevention of
safety accidents at the construction site. |
