Korea has the highest suicide rate in the world, and firefighters have the highest suicide rate among the professional population. As a result of the study, post-traumatic stress disorder education is essential in all occupations. Post-traumatic stress disorder is the most common disease and the biggest obstacle for firefighters in Korea. Firefighters who have suffered physical and mental damage in many types of disaster sites due to their extreme occupations are rapidly increasing the suicide rate in recent years. In order to maximize the effect of job training, education on post-traumatic stress disorder from new employees to leadership training is urgently needed.

This study investigated how the experience of victimization caused by inmates' violence might affect correctional officers' job-satisfaction and stress-related experience, burnout. Furthermore, it was also assessed if physical violence by inmates might result in officers' post-traumatic stress disorder. The results presented that officers responsible for security of prison cells reported serious degree of maladaptation in burnout experience, job-satisfaction, and post-traumatic stress disorder. Principal factor analysis of items to measure officers' victimization by inmates saturated a three-factor model to have the best fit. Three factors were psychological withdrawal, victimization by physical violence, and small disputes between inmates and officers. Additionally, officers were classified based on the experience of being victimized by inmates' physical abuse. The indices of chronic burnout and job-satisfaction were turned out to be much more maladjusted among officers abused by inmates physically. These results imply that victimization by inmates' physical violence produced significant degree of psychological symptoms such as post-traumatic stress disorder and chronic burnout experience. This relationship confirmed that there might be a causal effect of being physically abused by inmates on correctional officers' mental health problem such as post-traumatic stress disorder.
