  • In the event of a disaster (or accident), first of all, the ability to respond to an immediate disaster is important. This study investigated the disaster response capacity and the effects of disaster response exercise personnel. A questionnaire consisting of 28 items was used to assess disaster response capabilities. The questionnaire consists of contrast, preparedness initial response, warning, and response steps. Survey participants are self-service fire-fighters of small and medium-sized manufacturing companies participating in exercise. The effectiveness of the exercise. was measured by dividing the subjects before and after the exercise. Analyzing the difference between before and after exercise, it was confirmed that disaster response exercise. had significant effects on improving disaster response capacity. This study suggests that the disaster response exercise. has the effect on the disaster response capacity of the members and the necessity of disaster response exercise. As in the case study, if a company or organization regularly conducts disaster response exercise., its disaster response capabilities will improve. In addition, it is anticipated that in the event of a disaster (or accident), it will be possible to prevent or reduce property damage as well as property damage.

Effects of Occupational Trauma Exposure on Brain Functional Connectivity in Firefighters With Subclinical Post-Traumatic Stress Symptoms: A Resting-State Functional Magnetic Resonance Imaging Study (직업적 외상 노출이 역치 하 외상 후 스트레스 증상을 보이는 소방공무원의 뇌 기능적 연결성에 미치는 영향: 휴지기 기능적 자기공명영상 연구)

  • Objective : This study investigated brain functional connectivity in male firefighters who showed subclinical post-traumatic stress disorder (PTSD) symptoms. Methods : We compared the data of 17 firefighters who were not diagnosed with PTSD and 18 healthy controls who had no trauma exposure. The following instruments were applied to assess psychiatric symptoms: Korean version of the Post-traumatic stress disorder Checklist for DSM-5 (PCL-5-K), Beck Depression Inventory-II (BDI-II), Beck Anxiety Inventory (BAI). For all subjects, functional magnetic resonance imaging was performed, and functional connectivity was compared between the two groups (family-wise error-corrected p<0.05). Additionally, correlations between psychiatric symptoms and functional connectivity were explored. Results : The following connectivity was higher than that of healthy controls: 1) the central opercular cortex-superior temporal gyrus, 2) planum polare-parahippocampal gyrus, 3) angular gyrus-amygdala, and 4) temporal fusiform cortex-parahippocampal gyrus. The functional connectivity of 1) the lateral occipital cortex-inferior temporal gyrus, 2) superior parietal lobule-caudate, and 3) middle temporal gyrus-thalamus were lower in firefighters. In firefighters, the connectivity of the planum polare-parahippocampal gyrus showed a negative correlation with the severity of arousal symptoms (rho=-0.586, p=0.013). The connectivity of the middle temporal gyrus-thalamus showed a positive correlation with the severity of intrusion (rho=0.552, p=0.022) and arousal symptoms (rho=0.619, p=0.008). The connectivity of the temporal fusiform cortex-parahippocampal gyrus was negatively correlated with intrusion (rho=-0.491, p=0.045) and arousal (rho=-0.579, p=0.015). Conclusion : Our results indicate that the brain functional connectivity is associated with occupational trauma exposure in firefighters without PTSD. Therefore, this study provides evidence that close monitoring and early intervention are important for firefighters with traumatic experience even at a subthreshold level.
