Despite over eighty percent of industrial accidents were caused by unsafe behaviors, most safety programs still focus on changing workers’ internal status such as thinking and attitude rather than directly changing safe related behaviors. The purpose of this paper is to introduce the basic concepts and procedures of Behavior-Based Safety (BBS) which originated in applied behavior science (ABS), BBS attempts to change safety related behaviors by manipulating antecedents and consequences of workers’ behaviors. Also this paper introduces several case studies conducted globally in various industrial fields. These case studies highlight the procedures of BBS, their impacts on safety performance and accidents rate, and other business results. Based on these results, this paper proposes new guidelines for safety management.

본 연구는 졸음운전의 지표로 예상되는 심전도의 LF/HF 비율이 효과적으로 졸음운전을 예측하는지를 검증하는 것이었다. 본 연구는 총 31명이 참가하였으며, 가상 운전시뮬레이션 과제를 활용하여 진행하였다. 수면박탈이 운전 중 LF/HF 비율에 영향을 미치는지를 검증하기 위해 충분한 수면을 취한 조건과 수면이 박탈된 조건으로 실험을 실시하였다. 충분한 수면을 취한 조건에서 참가자는 전날 6시간 이상의 수면을 취한 후 30분동안 진행되는 가상 운전과제를 수행하였다. 수면이 박탈된 조건에서는 실험에 참여하기 전날에 참가자가 5시간 이하의 수면을 취하도록 유도한 후 60분 동안 진행되는 가상 운전 과제에 참여하도록 하였다. 참가자는 두 조건 모두에서 심전도를 측정할 수 있는 장비를 착용한 상태로 가상 운전 과제를 수행하였다. LF/HF 비율과 지각된 졸음운전과의 관계성을 확인하기 위해서 참가자가 가상 운전 과제를 수행하는 동안 10분간격으로 주관적 졸림정도를 측정하였다. 실험 결과 충분한 수면을 취한 조건보다 수면박탈 조건에서 참가자의 LF/HF 비율이 감소하였으며, 동일하게 주관적 졸림정도는 증가하였다. 또한 주관적 졸림정도가 LF/HF비율을 예측하는 것으로 나타났다. 따라서 LF/HF 비율을 통한 졸음 운전 예측은 타당한 것으로 나타났다.

The purpose of this study was to examine the effects of stress response on safety behavior and to explore moderating effect of safety climate between stress response and safety behavior. 224 workers were asked to respond to the questionnaires that measured various demographic variables, stress response, safety climates and safety behaviors. A hierarchical regression was conducted to identify variables that had significant relationships with safety behavior and to examine moderating effect of safety climate between stress response and safety behavior. Results indicated that the depression response significantly predicted safety behavior. It was found that the safety climate was also a significant predictor for safety behavior. In addition, safety climate had a moderating effect on the relation between depression and anger responses and safety behavior.

The purpose of this study was to examine the relative effectiveness of immediate feedback and informational prompt on safe sitting behaviors that may cause VDT syndromes. Participants were three white color workers and an ABCB within-subject design was adopted. Safety Posture System was developed specifically for the present study. The system could detect participants' unsafe sitting postures using sensors and provide feedback and prompt on the computer monitors. The results indicated that both immediate feedback and informational prompt considerably increased safe sitting behaviors. More importantly, the immediate feedback was more effective than the informational prompt in increasing safe sitting behaviors.
