This study was to determine differences and relations in nursing students' clinical practice stress and clinical competence by gender role identity. The study made a questionnaire survey of 450 nursing students of 2 colleges in J city, Gyeongnam, from June 1st to 30th, 2020. Data from 417 sheets were finally analyzed with descriptive statistics, χ2test, t-test, ANOVA, Scheffe test, correlation and hierarchial regression analysis. The analysis found that most of the participants belonged to undifferentiated type(34.3%) in gender role identity. Clinical competence showed significantly different(F=20.98, p<.001), but clinical practice stress showed no significant difference depending on that identity(F=1.56, p=.199). Clinical competence had positive correlations with the index of masculinity(r=.397, p<.001) or the index of feminity(r=.325, p<.001), but had no with clinical practice stress(r=.061, p=.217). Gender role identity turned out to be a factor that would significantly influence clinical competence(F=6.67, p<.001). These findings suggest that gender role identity of nursing students should be confirmed prior to clinical practice education and, thereon, interventions for clinical competence improvement should be developed.

This study was carried out to investigate the possibility of supplemental UV-B application to the hardening phase of container-grown Betula platyphylla seedlings. The containerized seedlings were grown in a growth chamber for four months and then treated with UV-B(UV-$B_{BE}$ $3.2KJ\;m^{-2}\;day^{-1}$ and $5.2KJ\;m^{-2}\;day^{-1}$) radiation and water stress regime(irrigation in one week interval) for four weeks. The differences in growth and physiological responses of the seedlings before and after the treatments were analyzed. UV-B radiation and water stress reduced height growth and leaf dry mass accumulation of the seedlings. The root collar diameter growth was reduced by UV-B radiation but increased by water stress. The reduction in leaf dry weight by UV-B radiation and water stress reduced T/R ratio of the seedling. The reduction in T/R ratio was the most apparent by water stress. Chlorophyll index observed by a chlorophyll meter was the lowest in the $5.2KJ\;m^{-2}\;day^{-1}$ of UV-B radiation, and those in the $3.2KJ\;m^{-2}\;day^{-1}$ and water stress were similar. UV-B radiation and water stress reduced both water content in the seedlings and leaf water potential, and increased leaf osmatic pressure. The water content of leaves and shoots was reduced more rapidly by UV-B radiation than by water stress treatment. In conclusion, growth responses and physiological changes in water relation by supplemental UV-B radiation which was applied to the hardening phase of container-grown Betula platyphylla seedlings were similar results to the water stress treatment.

Objectives : The coronavirus disease 2019 (COVID-19) outbreak is a global medical crisis imposing particular burden on public sector employees. The aim of this study was to investigate the psychiatric distress among public sector workers amid the COVID-19 pandemic. Methods : We conducted a cross-sectional study with 531 public sector workers in Gwangmyung city who completed Korean versions of the Perceived Stress Scale (PSS), Patient Health Questionnaire-9 (PHQ-9), and Impact of Event Scale-Revised-Korean (IES-R-K). Results : The results revealed more than moderate levels of stress (85.2%), depressive symptoms (22.2%), and posttraumatic stress symptoms (38.8%). PSS total score was significantly correlated with PHQ-9, IES-R-K total scores as well as IES-R-K subscale scores. Total scores on the PSS, PHQ-9, and IES-R-K were all inversely correlated with age. Conclusions : COVID-19-related workers experience considerable stress and depressive symptoms, with self-rated stress correlating significantly with depression scores. Age may serve as a protective factor against occupational stress and burnout. These findings highlight the need for adequate psychiatric screening and intervention for public sector workers.

Background: It is necessary to understand the correlation between stress and depression according to eating habits in the elderly. Purposes: To empirically verify the mediating effect of eating habits in the relationship between stress and depression in the elderly. Methods: we distributed an 'online questionnaire' to men and women aged 60 or more living in large cities, medium, and small-sized cities in Korea using Google questionnaires, and 365 replies were collected and used for analysis. Results: First, we found that stress in the elderly directly affected depression. In summary, an increment in the stress level of the elderly induces an increment in the depression level. Second, the eating habits of the elderly indirectly mediated the relationship between stress and depression. Conclusions: This study is meaningful in that it has verified eating habits have a mediating effect on the relationship between stress and depression in the elderly, and healthy eating habits of individuals can reduce depression. Therefore, counseling institution must check their daily eating habits when counseling the degree of depression of the elderly. In addition, eating habits are affected by stress, and it is necessary to grasp the individual stress index for the elderly who has terrible eating habits. Furthermore, it is needed to provide continuous nutrition education in institutions and communities to have proper eating habits.

The present study evaluated the systemic oxidative stress status during major orthopedic surgery in dogs. Sixteen dogs presented with various orthopedic diseases involving fractures or luxation of limbs. All patients underwent orthopedic surgery for treatment of fractures or luxation of limbs. A significant increase in the plasma total oxidant status (TOS) and oxidative stress index (OSI) levels in dogs after surgery was observed. Plasma total antioxidant status (TAS) levels were significantly decreased in dogs after surgery. The results of this study suggested that association or relationship in serum between TOS or TAS levels and redox imbalance were caused by surgical trauma in orthopedic disease conditions.

This study was to examine the difference of Anti-Stress Quotient of pre-puberty, puberty, and post-puberty time. pre-pubescent students 28 and pubescent students, 35 classified by questionnaires from elementary and middle school students located in the Y city were participated in this research. post-pubescent students 33 were sampled from college students' data collected by Braintech Corp. And analyzed by brainwaves, which could be obtained through QEEG BQ(Brain Quotient) Analysis. The result of this study is as follow: post-puberty time was increased Anti-Stress Quotient due to the decrease of the Body Stress and the Mental Stress. It means that the psychological characteristics of puberty time can be proven by not only method of questionnaires but also scientific brainwaves.

The purpose of this study was to examine the fitness of a Path model to represent relations between stress, social support, depression, and suicidal ideation in middle-aged males. The participants were 236 middle-aged males, and data were collected from April 11 to June 1, 2018. The analysis was performed using descriptive statistics and Pearson's correlations in PASW Ver. 21.0, and AMOS Ver. 18.0 (a statistical structural equation modeling program), fitness characteristics of the final model were RMSEA 0.05, GFI 0.98, AGFI 0.95, and NFI 0.98. The major study results were as follows. First, stress had a direct effect on depression and drinking, and social support had a direct effect on depression. Second, stress and social support both directly affected suicidal ideation. Results also suggested depression had partial mediating effects on relations between stress, social support, and suicidal ideation. We suggest a program be devised to reduce suicidal ideation by middle-aged males. It is hoped our results will provide basic data for future studies.

Our daily lives have changed a lot because of the COVID-19 pandemic. This is essential to reduce the spread of COVID-19 due to public health measures such as social distancing. At the same time, however, they are exposed to depression, anxiety disorders, depressive disorders, trauma and stress-related disorders. For this, we developed an application that can check HRV data and stress index by measuring ECG and PPG based on a Smart Watch device that can measure bio-signals in real time. In the case of the developed application, the heart rate is measured and displayed in real time to deliver basic exercise information by measuring exercise, steps and calories, and total distance, and smoothly based on blood pressure, heart rate, and HRV data as a measurement program. Through this, I believe that the IoT Smart Stress Care Application, which can manage mental health by itself, will be helpful to patients with stress and depressive trauma disorders.

Backgoround: This study aimed to examine the influence of anxiety sensitivity on task performance and physiological stress response, and to assess the effect of depression in this process for the youth population. Methods: We presented participants with an uncontrollable stress situation where they were required to perform mental arithmetic, based on the Montreal Imaging Stress Task (MIST). A total of 29 participants volunteered for this study. They completed the Anxiety Sensitivity Index-Revised and Patient Health Questionnaire-9 to measure their levels of anxiety sensitivity and depression. Two saliva samples, one before and one after the experiment, were collected to assess the change in cortisol levels as an index of physiological stress response. Results: Participants with high anxiety sensitivity showed lower performance on the mental arithmetic tasks and a significant increase in a salivary cortisol level, compared to those with low anxiety sensitivity. Furthermore, cortisol levels showed a remarkable increase where high anxiety sensitivity was coupled with depressed mood. In other hands, the levels of cortisol remained unchanged despite high anxiety sensitivity with low depressed mood. Conclusions: Our results confirm that the interaction between anxiety sensitivity and depression affects participants' task performance and stress response, as measured through behavioral tasks and physiological data with self-report indices. Also, through the physiological data, we examined that those who have a high level of anxiety sensitivity showed maladaptive responses under high stressful situation.
