Background: This study investigated the relationship between trauma exposure and suicidal ideation. Moreover, this study examines the moderating roles of organizational climate on the association between trauma exposure and suicidal ideation in Korean male firefighters. Methods: A total of 15,104 male firefighters who completed a questionnaire were analyzed. The data were obtained using an online self-administered questionnaire from the Firefighter Research on Enhancement of Safety and Health Study. Poisson regression analysis was performed to determine the effects of trauma exposure on suicidal ideation and the moderating effect of organizational climate. Results: The results showed that 389 firefighters (2.6%) responded that they had experienced suicidal ideation. In the final model, trauma exposure was positively related to suicidal ideation (adjusted risk ratio [aRR], 1.076; 95% confidence interval [CI]: 1.051-1.103), and organizational climate was negatively associated with suicidal ideation (aRR, 0.772; 95% CI: 0.739-0.806). Additionally, the interaction term (trauma exposure × organizational climate) was related to suicidal ideation (aRR, 1.016; 95% CI: 1.009-1.023). Conclusions: This study suggests that trauma exposure might play a significant role in developing suicidal ideation and that positive organizational climate moderates the negative effects of trauma exposure on suicidal ideation among firefighters. It is necessary to perform a follow-up study of various intervention strategies to maintain a healthy organizational climate or work environment. Such interventions should promote lasting trust within teams, provide social support and belonging, and nurture job value.

Purpose: The objective of this study was to investigate the appropriateness of the cross table lateral cervical X-ray used in the emergency department for severely traumatized Korean patients. Methods: Patients visiting our institution from May 2011 to May 2012, who had injury severity score (ISS) > 15 and who received a cervical X-ray in the emergency department, were included in this study. Data including demographics, ISS score, GCS score, and place where the x-ray was taken were collected to evaluate their relationship with appropriate coverage of the cervical X-ray. The appropriateness of a cervical cross lateral view X-ray was evaluated using exposure of the basion, and the opisthion, as well as the distal level of exposure. Results: Fifty-two patients were included in this study. The identification rate of the basion was 79.2%, and the identification rate of the opisthion was 88.7%. Complete exposure of C7/T1 was accomplished in 3.8% of the patients. The ISS was higher for X-ray taken in the trauma bay, but the range of exposure showed no difference between the places where the X-rays taken. Patients who had exposure of C 5/6 or more had lower body weight and body mass index (BMI) compared with unexposed patients. Conclusion: In severely traumatized Korean patients, the adequacy of the cross table lateral cervical X-ray was inappropriate in most cases. No difference was observed in the exposure range between the places where the X-rays were taken, and patients with less exposure showed higher body weight and higher BMI.

본 연구는 20대 성인의 n번방 관련 뉴스 노출과 간접 외상, 그리고 세상에 대한 신념 간의 관계를 실증적으로 탐구하기 위해 수행되었다. 이를 위하여, 20대 성인을 대상으로 온라인 조사 연구를 시행하였으며, 총 228명의 자료를 수집하였다. SPSS 25.0을 통해 분석한 결과, n번방 사건이 밝혀진 직후 관련 뉴스를 많이 접했을수록 당시에 더 높은 수준의 간접 외상을 경험하였던 것으로 나타났다. 또한, 간접 외상은 당시 뉴스 노출과 현재의 세상에 대한 신념간의 관계를 완전 매개하였다. 즉, 당시 뉴스 노출량이 많았을수록 간접 외상 수준이 높아졌으며, 높은 수준의 간접 외상은 세상에 대한 부정적인 신념과 관련되었다. 본 연구는 재난뿐만 아니라 성범죄 사건도 뉴스를 통해 제3자인 사람들에게 간접 외상을 불러일으킬 수 있음을 확인하였고, 뉴스 노출이 간접 외상을 매개로 세상에 대한 신념에 미치는 영향을 검증하였다는 데에 의의가 있다. 그러나 본 연구는 20대 성인에 한정되었으며, 연구 참가자 대부분이 여성이라는 점에서 한계를 가지므로, 추후 더 다양한 집단을 대표하는 표본으로부터 자료를 수집할 필요가 있다. 나아가서, 후속 연구로 뉴스 노출과 간접 외상의 관계를 정서 전염이 매개 혹은 조절할 가능성을 검토할 수 있을 것이다.

Childhood exposure to intimate partner violence (IPV) and other adversities has been shown to have adverse effects on health and well-being not only in childhood but also throughout the lifespan. This paper focuses on the prevalence of childhood adversities including exposure to IPV. The intersection of adverse childhood experiences and IPV victimization/perpetration in adulthood is also explored. The neurobiology of trauma is discussed and by understanding the impact of trauma on health, it is hoped that enhancement of resilience is possible. Based on the identification of protective factors at the individual, familial, and community level, examples of interventions that encourage safe, stable, and nurturing relationships between parents and children are described.

Objective : This study aimed at investigating the relationship between exposure frequency of job related trauma types and the PTSD symptoms severity of firefighters, in relation to the moderating effect that anger rumination plays in the association between those of them. Methods : We examined data from 116 firefighters from Gyeonggi-do. The following instruments were applied: the Life Events Checklist (LEC), the Korean version of the Anger Rumination Scale (K-ARS) and the Primary Care PTSD screen (PC-PTSD). Results : A higher exposure frequency of job related trauma types was associated with severe PTSD symptoms; we discovered, however, that anger rumination exacerbated their relationship. Conclusion : This study showed that anger rumination is one of the variables to exacerbate PTSD symptoms in firefighters. Therefore, the study emphasizes the need to consider the level of anger rumination when running a program to predict or mitigate PTSD symptoms in firefighters.

Exposure to a traumatic events gives people many post traumatic conditions resulting Post Traumatic Stress Disorder (PTSD) or Post Traumatic Growth (PTG). Some of them may come up with acute Stress Disorder and some may having with grievances. But most of people overcome their traumatic condition with using their Emotional Intelligence and Resilience capacities. This article is focused on indicating basic mechanisms and resources in which can be lead to have better social rehabilitation along with the matters that can be important in trauma coping. The later part of the article appeals the concept of social work theory highlighting the psych dynamic approach which can be impact positively on psycho social rehabilitation. Traumatic experiences are really unpredictable and it can be resulted Post Traumatic Stress Disorders, Post traumatic growth in the end. But developing skills that required to overcoming trauma is facilitated by the Emotional Intelligence, Resilience, and Coping capacities that people having with. Exposure to a traumatic experience and not having a PTSD is determined by the many other factors such as social support system and government facilitation of the wellbeing afterwards the trauma. Here in this article the basic components of Emotional Intelligence, Resilience, and coping mechanisms have been considered as the major factors.

Objective : Several earlier studies have reported similar symptoms in patients with posttraumatic stress disorder (PTSD) who have been repeatedly exposed to relevant media after disasters and trauma. This study aimed to examine the effects of indirect trauma experience through media rather than direct traumatic events on an individual's social life. Methods : Five hundred and fifty-four individuals participated in our online, self-reported questionnaire survey. All subjects were asked to complete a demographic questionnaire, Posttraumatic Diagnostic Scale, Beck Depression Inventory, the Impact of Event Scale-Revised, State-Trait Anxiety Inventory, Korean version of Alcohol Use Disorder Identification Test, Patient Health Questionnaire-15, Suicidal Behaviors Questionnaire-Revised. Participants were assessed in regards to their experience of violent media exposure within the past three months. Results : Data from our study indicates that the group exposed to violent media had significantly higher perceived stress, physical symptoms, insomnia, and suicide ideation in comparison to the control group. Among the major symptoms of PTSD, the proportion of intrusion symptoms was relatively high in the media exposed group. Conclusion : This suggests that indirect trauma caused by media exposure could cause post-traumatic stress symptoms. The PTSD caused by indirect trauma may have slight differences from the PTSD caused by direct trauma. Therefore, it is necessary to understand, prevent, and control the adverse effects of media.

Trauma remains a significant healthcare burden, causing over five million yearly fatalities. Notably, the liver is a frequently injured solid organ in abdominal trauma, especially in patients under 40 years. It becomes even more critical given that uncontrolled hemorrhage linked to liver trauma can have mortality rates ranging from 10% to 50%. Liver injuries, mainly resulting from blunt trauma such as motor vehicle accidents, are traditionally classified using the American Association for the Surgery of Trauma grading scale. However, recent developments have introduced the World Society of Emergency Surgery classification, which considers the patient's physiological status. The diagnostic approach often involves multiphase computed tomography (CT). Still, newer methods like split-bolus single-pass CT and contrast-enhanced ultrasound (CEUS) aim to reduce radiation exposure. Concerning management, nonoperative strategies have emerged as the gold standard, especially for hemodynamically stable patients. Incorporating angiography with embolization has also been beneficial, with success rates reported between 80% and 97%. However, it is essential to identify the specific source of bleeding for effective embolization. Given the severity of liver trauma and its potential complications, innovations in diagnostic and therapeutic approaches have been pivotal. While CT remains a primary diagnostic tool, methods like CEUS offer safer alternatives. Moreover, nonoperative management, especially when combined with angiography and embolization, has demonstrated notable success. Still, the healthcare community must remain vigilant to complications and continuously seek improvements in trauma care.
