Occupational hazards of firefighting and rescue works include frequent exposure to emergencies and life-threatening situations. These stressful work conditions of being constantly under pressure and exposed to potentially traumatic events put them at higher risk of developing posttraumatic stress disorder (PTSD), compared to the general population. PTSD is a potentially debilitating mental disorder, due to persistent intrusive thoughts, negative alterations of mood and cognition, hypervigilance, avoidance of similar situations and reminders, and re-experiences of the traumatic event. Previous studies have shown a relatively high prevalence of PTSD among firefighters, indicating the need for a systematic approach of early detection and prevention. Therefore, a critical review of the current literature on PTSD in firefighters would provide valuable insights into developing effective prevention and intervention programs. Literature indicated that there are risk factors of PTSD in firefighters, such as pre-existing depression, anxiety, sleep disorders, occupational stress, physical symptoms, and binge drinking, whereas social support and adequate rewards are protective factors. Although there are differences in the prevalence of PTSD across studies, partly due to various assessment tools utilized, different sample sizes, and sample characteristics, over one tenth of the firefighters were estimated to have PTSD. The current review warrants further investigations to precisely assess PTSD and co-morbid mental disorders, functional outcomes, and associated factors, and to develop evidence-based preventive and interventional programs to help firefighters with PTSD.

Behavioral analysis in mice provided important contributions in helping understand and treat numerous neurobehavioral and neuropsychiatric disorders. The behavioral performance of animals and humans is widely different among individuals but the neurobehavioral mechanism of the innate difference is seldom investigated. Many neurologic conditions share comorbid symptoms that may have common pathophysiology and therapeutic strategy. The forced swim test (FST) has been commonly used to evaluate the "antidepressant" properties of drugs yet the individual difference analysis of this test was left scantly investigated along with the possible connection among other behavioral domains. This study conducted an FST-screening in outbred CD-1 male mice and segregated them into three groups: high performers (HP) or the active swimmers, middle performers (MP), and low performers (LP) or floaters. After which, a series of behavioral experiments were performed to measure their behavioral responses in the open field, elevated plus maze, Y maze, three-chamber social assay, novel object recognition, delay discounting task, and cliff avoidance reaction. The behavioral tests battery revealed that the three groups displayed seemingly correlated differences in locomotor activity and novel object recognition but not in other behaviors. This study suggests that the HP group in FST has higher locomotor activity and novelty-seeking tendencies compared to the other groups. These results may have important implications in creating behavior database in animal models that could be used for predicting interconnections of various behavioral domains, which eventually helps to understand the neurobiological mechanism controlling the behaviors in individual subjects.

Background: The purpose of this study was to investigate the effects of dental hygiene students' communication ability and conflict management types on adaptation to college life improve adaptation to college life and to suggest strategies to play a role as a professional dental hygienist in clinical practice. Methods: The subjects of this study were selected by random sample extraction of dental hygiene students from two colleges in Gyeonggi and one Chungcheong area. The survey was conducted online for dental hygiene students from July 20 to October 31, 2020. In order to comply with research ethics, this study was investigated with the consent of the subjects. The sample was analyzed for the final 351. Results: Dental hygiene students' communication ability was 3.74 points, conflict management types was 3.01 points, and adaptation to college life was 3.30 points. In the type of conflict management according to the general characteristics, the problem-solving method, the avoidance method, the compromise method, and the concession method showed statistically significant differences in major satisfaction. Among the types of conflict management, the highest positive correlation (r=0.613) was shown in the relationship between the problem-solving method and the compromise method. Factors influencing the adaptation to college life were concentration, forced method, self-disclosure, conversational coherence, and social relaxation. Conclusion: This study is significant in that it derives sub-areas of communication ability and conflict management types that influence adaptation to college life. In the future, there is a need to improve the quality of dental hygienists by continuously conducting research on the types of conflict management targeting dental hygienists, and responding more proactively and actively to conflict situations in the clinical field.
