Objective: This study investigated how educational levels modify the relationship between the standard deviation of NN intervals (SDNN) of heart rate variability and the development of post-traumatic stress disorder (PTSD). Methods: Participants with physical injuries were enrolled from a trauma center and monitored over two years. Initial assessments included SDNN and educational attainment, along with socio-demographic and clinical variables. PTSD diagnoses were made at 3, 6, 12, and 24 months post-injury using the Clinician-Administered PTSD Scale for DSM-5.Logistic regression analyses were conducted. Results: Of the 538 participants, 58 (10.8%) developed PTSD during the follow-up period. A significant interaction effect was observed: lower SDNN was significantly linked to PTSD in individuals with higher education, but not in those with lower education. Conclusion The study identified education-dependent associations between SDNN and PTSD development, emphasizing the importance of tailored PTSD prevention strategies that consider both SDNN and educational levels.

Objectives: This study was performed to identify factors associated with self-perceived depression among Korean adolescents during the coronavirus disease-2019 (COVID-19) pandemic. Methods: A total of 1,710 middle and high school students (54.7% boys, 45.3% girls) participated in a cross-sectional survey. The self-administered questionnaire included items assessing the changes in perceived depression and daily life patterns during the COVID-19 pandemic. Other questionnaires included sociodemographic data, three item version of the UCLA Loneliness Scale, Gratitude Questionnaire-6, and Big Five Inventory-10. Multivariable logistic regression was used to examine the factors associated with increased perceived depression during COVID-19 pandemic. Results: The prevalence rate of perceived depression was 18.4%. The multivariate logistic regression analysis revealed that high loneliness, neuroticism, decreased social relationships, increased familial conflict, increased internet using time, irregular meal pattern, and high perceived academic stress were significantly associated with perceived depression. Conclusions Our findings suggest that interventions aimed at coping with stress and regulate perceived depression due to sudden life style changes are necessary for adolescents, as such a global situation like COVID-19 pandemic could be prolonged or repeated.

In the rapidly evolving healthcare environment, radiologists strive to establish their rightful place.Thus, there is a need for enhanced outpatient and clinical education within the Department of Radiology and exploration of its methodologies. Accordingly, the Korean Society of Radiology established a task force to investigate the clinical and outpatient practice status of radiologists overseas, current state of related education, involvement of other specialties in radiologic practices and education in Korea, and clinical and outpatient practice status among Korean radiologists. Furthermore, a survey on clinical competency enhancement was conducted among the members of the Korean Society of Radiology. These findings suggest the need for visibility and clinical competency enhancement in radiologists and methodologies for strengthening clinical competencies.
