Objective : The goal of this study was to compare several parameters, including wall shear stress (WSS) and flow pattern, between unruptured and ruptured anterior communicating artery (ACoA) aneurysms using patient-specific aneurysm geometry. Methods : In total, 18 unruptured and 24 ruptured aneurysms were analyzed using computational fluid dynamics (CFD) models. Minimal, average, and maximal wall shear stress were calculated based on CFD simulations. Aneurysm height, ostium diameter, aspect ratio, and area of aneurysm were measured. Aneurysms were classified according to flow complexity (simple or complex) and inflow jet (concentrated or diffused). Statistical analyses were performed to ascertain differences between the aneurysm groups. Results : Average wall shear stress of the ruptured group was greater than that of the unruptured group (9.42% for aneurysm and 10.38% for ostium). The average area of ruptured aneurysms was 31.22% larger than unruptured aneurysms. Simple flow was observed in 14 of 18 (78%) unruptured aneurysms, while all ruptured aneurysms had complex flow (p<0.001). Ruptured aneurysms were more likely to have a concentrated inflow jet (63%), while unruptured aneurysms predominantly had a diffused inflow jet (83%, p=0.004). Conclusion : Ruptured aneurysms tended to have a larger geometric size and greater WSS compared to unruptured aneurysms, but the difference was not statistically significant. Flow complexity and inflow jet were significantly different between unruptured and ruptured ACoA aneurysms.

Purpose : The purpose of this study was to identify the effect of clinical nurse's locus of control of personality on job stress and job satisfaction and organizational commitment out of organizational effectiveness. Methods : The subjects were 463 staff nurses, who were employed in four university hospitals located in Seoul, Pusan and Kyungki-do. Data was collected from October 4th to October 14th in 2000 by a self-report questionnaire. Data was analyzed by the SAS for the general characteristics of the subjects, descriptive statistics, test for reliability and correlations. The effect of variables were tested using the Lisrel 8.12(a) program. Results : With the findings from this study, the internal-external locus of control affects job stress directly. Also it affects job satisfaction directly and via job stress indirectly. But it affects organizational commitment only via job stress and job satisfaction indirectly. Direct effect of locus of control to organizational commitment is not significant. Job stress affects job satisfaction and organizational commitment out of organizational effectiveness directly. Finally, job satisfaction was direct predictor of organizational commitment. Conclusion : Therefore, nursing managers ought to develop social learning programs to change the perception of individual personality and job stress management programs in order to improve organizational effectiveness.

Purpose: The purpose of this study was to identify the predictors of job stress in hospital nurses. The predictors of job stress were the subject's general characteristics, communication style, critical thinking disposition and job satisfaction. Methods: 294 nurses who had worked in a hospital participated in this study. The data were analysed with descriptive analysis methods including a t-test, ANOVA, Scheffe test, Pearson correlation coefficient and multiple regression analysis. Results: The job stress score for nurses was 111.6. There was a statistically significant difference between job stress and marriage status (p<.001), education (p<.001), clinical career (p<.001), position (p<.001), communication style (p<.001), critical thinking disposition (p<.001), and job satisfaction (p<.001). Critical thinking disposition, job satisfaction and clinical career together accounted for 36.88% of the total variation in job stress. Conclusion: Based on the findings of this study, the development of a nursing intervention program that can lead to an improvement in critical thinking disposition is suggested.

Purpose: The purpose of this study is to examine the effects of clinical art therapy programs utilized at schools on adolescents' suicidal thoughts and stress relief and to validate their effectiveness as a type of adolescent suicide prevention program. Methods: 12 sessions of clinical art therapy for youth suicide prevention were provided, once a week for 90 minutes, for 20 students at five middle schools in Seoul who were at high risk of committing suicide. By using the paired sample t-test, the study presented qualitative data on the analysis of pre- and post- questionnaires and on the subjects' EEG test and saliva test. Results: First, through the clinical art therapy program, the subjects' happiness index improved significantly while their scores of depression and suicidal ideation (suicidal thoughts) decreased. Second, in the EEG and saliva test conducted after the art therapy sessions, emotional stability increased and stress was reduced significantly. Third, according to the results of pre- and post- K-HTP tests and individual activities, the subjects started to recognize the seriousness of suicide and show emotional stability and positive changes in overall attitudes, valuing the rights and life of their own 'precious selves' (self respect). Conclusion: The results of this study indicate that the clinical art therapy program is significantly effective at preventing suicidal ideation by reducing suicidal impulses and depression, by increasing the happiness index, which can serve as a protective factor against suicide, and by increasing emotional stability while reducing stress. Based on the results, there is a need to develop policy measures regarding art therapy programs which can be utilized at schools.

We investigated the work-life balance of clinical professors in charge of patient care, research, and education at medical schools and the demand for work-life balance support according to position (professor, associate professor, or assistant professor). In total, 163 clinical professors completed the consent form and participated in the study. They filled out an online survey consisting of questions about essential characteristics, a work-life balance test, stress, burnout, work-life satisfaction, and work-life balance support needs. We analyzed the results by analysis of variance and cross-tabulation using IBM SPSS ver. 23.0. Differences were found in work-life balance, stress, burnout, and satisfaction with life and work by position. The requirements for support for work-life balance also varied by professional status. Professors had a higher balance between life and work than associate professors or assistant professors. The specific requirements for work-life balance support were also slightly different for each position. Overall, there was a high demand for work process simplification and efficiency for work support, flexible working hours and sabbatical years for family and leisure, and career management consulting and training support for growth. Assistant professors and associate professors had a lower level of work-life balance than professors, as well as higher levels of stress and burnout. Professors' job satisfaction was also higher than that of the other groups. Based on the results of this study, we hope that a healthy work environment can be established through work-life balance support suitable for clinical professors' positions.

Objectives: Academic stress poses a significant risk for the mental health of medical students, and a feasible group intervention program for managing academic stress is required. The purpose of this study was to examine the clinical effectiveness of emotional freedom techniques (EFT) on the mental health of Korean medical students. Methods: The class of first-year medical school students (n=36) participated in an after-school EFT group intervention program comprising six sessions (15 minutes/session, three weeks) to analyze its clinical effectiveness as a single-group test-retest clinical study. The changes in the Perceived Stress Scale (PSS), Test Anxiety Inventory (TAI), Positive and Negative Affect Schedule (PANAS), and State-Trait Anxiety Inventory (STAI) scores were examined using a paired t-test and Cohen's D at post-EFT and two-week follow-up. Results: There were significant curtailments at post-EFT and follow-up measures in TAI-Total (t=2.704 and t=3.289), TAI-Worry (t=2.297 and t=2.454), TAI-Emotionality (t=2.763 and t=3.654), PSS-Negative Perspective (t=2.659 and t=3.877), and PANAS-Negative Affect (t=2.885 and t=3.259) subscales, however not in PSS-Positive Perspective (t=-1.279 and t=-1.101) and PANAS-Positive Affect (t=0.194 and t=-0.122) subscales. The trait anxiety (t=2.227) was significantly mitigated in the post-EFT measure and the state anxiety (t=2.30) in the follow-up measure. Conclusions: The EFT group intervention alleviated test stress, negative affect, and anxiety in the Korean medical students. This study contributes to an understanding of academic stress and EFT intervention in the competitive environment of medical education.

Objectives: This study aims to serve as basic data for improving human resource management and the quality of work at dental hospitals and clinics by examining the relationship among clinical dental hygienists' emotional labor, job stress, and turnover intention. Methods: A self-reported questionnaire was completed by 220 dental hygienists in hospitals and clinics from March 11 to April 26, 2019. Data were analyzed using SPSS 20.0. For participants' burnout, job stress, emotional labor, and turnover intention based on general and occupational characteristics were analyzed using a t-test and one-way ANOVA. After performing a one-way ANOVA, a Duncan test was performed for mean comparison. Pearson's correlation analysis was conducted to determine correlations between variables, and stepwise multiple regression was performed to examine the factors that affect burnout. Results: Clinical dental hygienists' mean burnout was 3.05 points, and the factors that affect such burnout were turnover intention, job stress, and emotional labor. Burnout was higher when job satisfaction was low, turnover intention was low, and emotional labor was high, with a 29.3% explanatory power. Conclusions: For effective human resource management of dental hygienists, it is necessary to develop and implement programs that can reduce emotional labor and burnout.

Metabolic syndrome such as, hypertension, diabetes, obesity, dyslipidemia etc are well known lifestyle diseases which threaten a health state. The purpose of this study is to evaluate antioxidant status and reactive oxygen species (ROS) in various stressful conditions. A group of persons (n=28) were enrolled in this study and stress status was evaluated using questionnaire of psychological well-being index (PWI-SF) and hematologic analysis of free oxygen radical defense (FORD), free oxygen radical test (FORT), lipid profiles and serum cortisol level. Analysis was done according to stress index, BMI status and overtime working. Blood samples from diabetics were used for control. Results are as in followings: Higher PWI-SF group showed higher FORT. Obese persons with BMI > $25kg/m^2$ showed statistically lower FORD (p<0.05) and higher FORT level (p<0.01). When compare with diabetics, an overweight group had similar levels in FORD and FORT while a normal body weight group showed quite different with diabetics in FORD (p<0.001). Higher ROS group has higher triglyceride, CRP and insulin levels but lower in FORD and HDL-cholesterol levels. Overtime working at night showed no meaningful result against our expectations. These results suggested that obesity showed most unfavorable correlations in an antioxidant status in various situations.
