Purpose : To investigate academic stress, coping method, and stress symptoms of high school students. Methods : Four hundreds-forty five high school students were studied from 14th July to 21th July, 2006. All subjects were in 1st, 2nd and 3rd grade of two high school in Seoul. The academic stress, coping method and stress symptoms were evaluated by questionnaire. Results : Male students showed more academic stress than female students. There was a significant difference in the academic stress according to sex. The 2nd grade students show the highest score of academic stress in the 3 factors(parents, teacher, and friend). Male students used more active coping methods to academic stress than female students. There was a significant difference in the coping methods to academic stress according to sex. There were positive correlations between the academic stress and the stress symptoms. Among the academic stress factors, parents and teacher factor influenced physiologic, psychologic, and behavioral symptom of stress symptoms. The friend factor influenced psychologic and behavioral symptom of stress symptoms. Conclusion : According to the study results, we must provide high school students more effective coping methods to academic stress at school environment.

Purpose: The purpose of this study was to investigate how college students' perceived stress, cognitive stress, and somatization affect their heart rate variability (HRV). Methods: This study is a cross-sectional survey research on 191 university students, registered at the G University. The perceived stress scale (PSS) and cognitive stress response scale, were used to assess level of stress. The somatization symptom scale of the Symptom Check List 90 (SCL-90), was used to assess level of somatization caused by stress. To assess heart rate variability (HRV), we conducted a five-minute test using a pulse wave analyzer, to analyze short-term HRV. Results: The SCL-90 somatization score had relatively high positive correlation (p< .001) with cognitive stress, but low positive correlation (p< .001) with perceived stress. Cognitive stress response had low negative correlation (p< .001) with 1nSDNN and 1nRMSSD among HRV parameters. Perceived stress was not correlated with HRV. Multiple regression analysis showed that variables of perceived stress, cognitive stress, and somatization symptoms, could not explain HRV. By contrast, one of the HRV indicators, 1nSDNN, was affected by age, gender, and aggressive-hostile thought, the latter being a subscale of the cognitive stress response scale. Conclusion: This study suggests that stress evaluation for people in early adulthood will be more effective, if the evaluation examines cognitive stress and heart rate variability.

This study was designed to identify the relationships of role-conflict and role-overload, coping strategies, and stress response of clerical workers. The subjects were 115 clerical workers from two company. The instruments were the role-conflict and role-overload scale developed by Lee(1989), coping scale developed by Latack(1986), and the stress response scale developed by Chang(1993). Analysis of data was done by descriptive statistics, Cronbach's $\alpha$, Pearson correlation coefficietnt, ANOVA. The results of this study were summarized as follows ; 1. The average score for the level of stress response was $83.6({\pm}9.1)$. The high risk stress group was 86.1% of the clerical workers, the latent stress group members was 13.9%, and healthy group was 0%. The overall stress level was very high. 2. Considering the coping strategies by sociodemographic factors, the use of control coping strategies showed significant differences by work-time. The use of symptom management coping strategies showed significant differences by sex, age, married status, year of career, pay, and type of work. The organizational coping strategies showed significant differences by year of education and type of work. 3. The clerical workers who had worked below 44 hours per week complained significantly lower stress response(F=4.942, p<.05). 4. Above 65% of all respondents answered that they needed all of organizational level coping strategies. 5. The role-confilct positively related to escape and organizational level coping strategies(r=.562, r=.495, p<.05). The role-overload didn't related to individual level coping strategies, but positively related to organizational level coping strategies(r=.320, p<.05). 6. The control coping strategies and the escape coping strategies positively related to symptom management, organizational level coping strategies(r=.409, r=.324, r=.316, r=.339, p<.05). 7. The relationship between role-related stress and stress response revealed positive correlation(r=.482, r=.431, p<.05), and the relationship between stress response and control, symptom management coping strategies revealed negative cor-relation(r=-.3204, r=-.3146, p<.05). In conclusion, this study revealed that relationship of role related stress, coping strategies, stress response was statistically significant. The result of this study support that coping strategies vary across situation of stress. Based on survey results, future studies should consider coping strategies in specific stress situation and concept of symptom management coping strategy. Also organizational or training interventions could be developed and initiate to help to increase the use of adaptive coping strategies in light of individual and situational differences.

Information on work stress and mental health status of industrial workers was required for optimum staffing and health care management. This study dealt with the relationship between mental health status examined by PSI(psychiatric symptom index) and socio-demographic variables. Especially this study attempted to find relevant determinants of the stress and mental health through multiple stepwise regression analysis based on data obtained from 687 occupational workers. The findings of this study were as follows; Mean scores of symptom dimension were higher in youth, female, more educated, unmarried and divorced, and workers in the noisy condition and short duration in job. And it showed high scores in long duration in job for anxiety; college educated for anger; unmarried for cognitive disturbance. The factors affecting the mean scores of psychiatric symptom index were varied according to the types of symptom: age, sex and duration in job for anxiety; age, sex, living with parent, education and marital status for anger; sex and marital status for depression; noisy condition and sex for cognitive disorder.

Objectives : The goal of this study is to investigate how occupational stress affects temporomandibular disorders (TMD), dry mouth and oral symptoms. Methods : For this study, workers from 5 areas were selected and the survey was carried out from June 1st to 30th, 2012. A total of 410 questionnaires were analyzed. Results : The analysis of the structural model shows that occupational stress has no significant influence on temporomandibular disorder and dry mouth symptoms, but does affect other oral symptoms. The results also reveal that dry mouth symptom and temporomandibular disorder both have a significant effect on oral symptoms. Conclusions : Oral symptoms and job stress appeared to directly and indirectly influence the psychological and social factors of job stress. A systemic investigation on the improvement of oral health in workers is urgently required.

Objective : The purpose of this study was to investigate strategies used to cope with stress and the cognitive characteristics of somatic symptom perception in patients with generalized anxiety disorder(GAD). Methods : A total of 55 patients meeting DSM-5 criteria for GAD and 55 normal controls were recruited for participation in this study. We evaluated subjects using The Way of Stress Coping Questionnaire (SCQ), Somato-Sensory Amplification Scale (SSAS), Symptom Interpretation Questionnaire (SIQ), and the Generalized Anxiety Disorder for 7 Item (GAD-7). We analyzed data using an independent t-test and Pearson's correlation analysis. Results : In terms of SCQ, GAD patients presented significantly lower scores on seeking social support and higher scores on wishful thinking than normal controls. GAD patients had significantly greater amplification of physical sensation in SSAS and higher scores in physical, psychological interpretation subsets of SIQ than normal controls. GAD-7 scores were positively correlated with physical interpretation scores on SIQ. Conclusion : Results reveal that patients with GAD have insufficient coping strategies for stress, greater amplification of body sensations, and tendency towards a physical, psychological interpretation of somatic symptoms.

Purpose: This study aimed to investigate the effect of stress and oral parafunctional habits on temporomandibular joint disorders (TMD) in college students. Methods: An online survey comprising 354 questionnaires was conducted from May 23, 2020, to June 21, 2020. The collected data were analyzed using Student's t-test, one-way analysis of variance, correlation tests, and multiple regression analysis. Results: The stress symptom score was higher in females than in males. The symptoms of physical stress were significantly higher among students from the Department of Public Health, whereas those of psychological stress were higher among students from the Department of Physical Education. Both TMDs and oral parafunctional habits were higher among females, students of the Departments of Arts and Physical Education, and seniors. The higher the stress symptom level, the higher the scores for TMD and oral parafunctional habits. TMD and oral parafunctional habits were found to be most affected by physical stress. Conclusion: These findings indicate that a reduction in physical stress is required to decrease the prevalence of oral parafunctional habits and TMDs among college students. This can be achieved by the incorporation of physical activity programs, which may aid in reducing the symptoms of physical stress.

Objectives: Previous epidemiological studies about oxidative stress and depression are limited by hospital-based case-control design, single-time measurements of oxidative stress biomarkers, and the small number of study participants. Therefore, in this study, we analyzed the association between biomarker of oxidative stress and depressive symptom scores using repeatedly measured panel data from a community-dwelling elderly population. Methods: From 2008 to 2010, a total of 478 elderly participants residing in Seoul, Korea, were evaluated three times. Participants underwent the Korean version of the Short Form Generic Depression Scale (SGDS-K) test for screening depression, and urinary malondialdehyde (MDA) levels were measured as an oxidative stress biomarker. We used a generalized estimating equation with a compound symmetry covariance structure to estimate the effects of oxidative stress on depressive symptom scores. Results: A two-fold increase in urinary MDA concentration was significantly associated with a 33.88% (95% confidence interval [CI], 21.59% to 47.42%) increase in total SGDS-K scores. In subgroup analyses by gender, a two-fold increase in urinary MDA concentration was significantly associated with increased SGDS-K scores in both men and women (men: 30.88%; 95% CI, 10.24% to 55.37%; women: 34.77%; 95% CI, 20.09% to 51.25%). In bivariate analysis after an SGDS-K score ${\geq}8$ was defined as depression, the third and the fourth urinary MDA quartiles showed a significantly increased odds ratio(OR) of depression compared to the lowest urinary MDA quartile (third quartile OR, 6.51; 95% CI, 1.77 to 24.00; fourth quartile OR, 7.11; 95% CI, 1.99 to 25.42). Conclusions: Our study suggests a significant association between oxidative stress and depressive symptoms in the elderly population.

Purpose: The study aimed to determine the impact of post-traumatic stress and ways of stress coping on problem drinking in firefighters. Methods: Data were collected from May 11 to June 11, 2015, in fire brigades across South Korea. Participants were 183 male firefighters who used self-report questionnaires containing questions from the Impact of Event Scale-Revised (IES-R), Ways of Coping Checklist (WCC), and Alcohol Use Disorders Identification Test (AUDIT). Data were analyzed using $x^2$ test, t-test, and logistic regression with the SPSS/WIN 21.0 program. Results: The prevalence of PTSD among firefighters was 36.7% and that of problem drinking was 39.3%. Firefighters with single (OR=0.23, 95% CI=0.038~1.321) and married status (OR=0.46, 95% CI=0.069~3.040) were less likely to have problem drinking than those who were divorced or bereavement. Those with invasion symptoms (OR=1.17, 95% CI=1.031~1.327) and hyperarousal symptoms (OR=0.85, 95% CI=0.722~0.989) were more likely to have problem drinking than those with avoidance symptoms. Conclusion: Post-traumatic stress symptom was a major risk factor that increased problem drinking, and married status reduced problem drinking. There is a need to develop post-traumatic stress symptom management program and early education content for symptom management.
