ABSTRACT
Cox proportional hazard regression, which focuses on the distribution of survival time, is widely used to determine the relationship between survival and multiple risk predictors. For thermal stress accidents, which are heat-dependent events, Cox proportional hazard regression focusing on the distribution of thermal conditions such as ambient temperature can be applied, and the hazard ratios of related factors indicate the strength of the accident risk. To reveal some of the personal, environmental, and behavioral characteristics associated with the risk of thermal accidents, thermal accident cases and climatic conditions published on the web were analyzed by Cox proportional hazard regression using ambient temperature as a functional parameter.
Keywords: Cox proportional hazard regression, thermal accidents, heat-dependent events, personal-environmental-behavioral characteristics.
