고령근로자의 만성질환과 건설현장 휴먼에러와의 상관성 연구

Abstract

In Korea, the number of elderly workers is increasing due to the aging population, and disasters caused by elderly workers are also increasing, resulting in about 49% of disasters and 63.6% of deaths in 2022. In order to reduce these elderly workers' disasters, we would like to study how human errors of elderly workers at construction sites are related to the individual health of workers. In particular, we would like to contribute to reducing disasters for elderly workers at construction sites by studying the relationship between chronic diseases that more than 40% of the Korean population experiences and about 80% of senior citizens aged 65 or older suffer from one or more.
 This study aims to empirically study the effect of chronic diseases on human error at construction sites and the causal relationship between lifestyle-mediated effects of elderly workers in the construction industry. To statistically verify this, 286 workers were surveyed at 12 construction sites across the country. Among the collected data, 260 copies, excluding 26 unfaithful answers, were regression analyzed using version 2.3.28 of the self-hair ratio using R language.
 The results of this study are summarized as follows.
 First, it was confirmed that the first factor of lifestyle, ma1 (the number of drinking), ma2 (the amount of drinking), and ma7 (smoking), have no direct mediating effect when the independent variable, chronic disease, affects the dependent variable, human error. Second, it was confirmed that ma3 (sleep disorder) and ma4 (stress), two factors of lifestyle, have a direct mediating effect when chronic diseases, which are independent variables, affect human errors, which are dependent variables.
 It has been verified that chronic diseases of elderly workers have a significant impact on human errors at construction sites, and in particular, sleep disorders and stress of elderly workers have been confirmed to have a positive effect on human errors. Thus, in addition to various measures in the workplace to reduce human errors so far, it is necessary to consider ways to contribute to reducing human errors in construction sites by paying attention to workers' health care measures such as improving the quality of sleep for elderly workers and stress reduction measures.
