Stress not only brings disorders in social, family life but brings also changes in eating behaviors so that the imbalance of food intake is induced. Our study was carried out to find out the association between the degree of stress and eating behaviors for the subjects of 262 female college students in the Suwon area. The study instrument was a structured questionnaire composed with questions about demographic data, food preferences, questions related to life styles, and health. All of the collected data was analyzed by the degree of stress score, grouping into high(25〈) and low stress group(〈=25). High stress group showed unhealthy lifestyles, higher percentage of irregular menstruation, smoking, dizziness, higher amount of alcohol consumption. They also showed higher preference rate of spicy foods including hot foods, oil based foods and showed percentage of removing visible fat when eating meats. They more wanted to control weight and prefers snacking compared to low stress group. These results show that stress changes in eating behaviors in a way of unhealthy life styles.

Purpose : The purpose of this study is to investigate the effects of sleep duration on stress and depression in college students. The results obtained will be used as a foundational framework for fostering a healthy sleep culture among college students and for formulating measures to improve the quality of their sleep. Ultimately, we intend to produce a publicity and educational material. Methods : For this study, a survey involving 100 college students was conducted, after which data based on a final total of 95 respondents were analyzed. The information on stress and depression were first analyzed in terms of general characteristics and then organized based on the data collected to investigate the effects of sleep duration on stress and depression. The participants were divided into the following groups: "less than 6 hours," "6 to 7 hours," and "7 to 8 hours." BEPSI-K (Brief encounter psychosocial instrument-Korean) was used for stress evaluation, while K-CESD-R (Korean version of center for epidemiologic studies depression scale-revised) was utilized for depression evaluation. Results : First, according to sleep duration, the BEPSI-K scores showed a statistically significant difference in each group (p<.01). In the post-hoc test, there was a difference among the "less than 6 hours" group, the "7 to 8 hours" group. A statistically significant difference was noted (p<.01). In addition, sleep duration had a statistically significant effect on the negative (-) direction of the BEPSI-K (p<.01). Second, the K-CESD-R score according to sleep duration showed a statistically significant difference in each group (p<.01). Notably, in the post-hoc test, the "less than 6 hours" group differed from the "6 to 7 hours" group, "7 to 8 hours" group. A statistically significant difference was noted (p<.01). In addition, sleep duration had a statistically significant effect on the negative (-) direction of the K-CESD-R (p<.01). Third, for the correlation between sleep duration and stress and depression, a negative (-) correlation was found between sleep duration and BEPSI-K and K-CESD-R. Meanwhile, a positive (+) correlation was found between BEPSI-K and K-CESD-R. Conclusion : Based on the findings of this study, the sleep duration of college students has an effect on stress and depression. The results of this study can be used as a foundational framework in formulating a plan for improving the quality of sleep of college students.

DJ-1 is one of the causative genes of early-onset familial Parkinson's disease (PD). As a result, DJ-1 influences the pathogenesis of sporadic PD. DJ-1 has various physiological functions that converge to control the levels of intracellular reactive oxygen species (ROS). Based on genetic analyses that sought to investigate novel antioxidant DJ-1 downstream genes, pyruvate dehydrogenase (PDH) kinase (PDK) was demonstrated to increase survival rates and decrease dopaminergic (DA) neuron loss in DJ-1 mutant flies under oxidative stress. PDK phosphorylates and inhibits the PDH complex (PDC), subsequently downregulating glucose metabolism in the mitochondria, which is a major source of intracellular ROS. A loss-of-function mutation in PDK was not found to have a significant effect on fly development and reproduction, but severely ameliorated oxidative stress resistance. Thus, PDK plays a critical role in the protection against oxidative stress. Loss of PDH phosphatase (PDP), which dephosphorylates and activates PDH, was also shown to protect DJ-1 mutants from oxidative stress, ultimately supporting our findings. Further genetic analyses suggested that DJ-1 controls PDK expression through hypoxia-inducible factor 1 (HIF-1), a transcriptional regulator of the adaptive response to hypoxia and oxidative stress. Furthermore, CPI-613, an inhibitor of PDH, protected DJ-1 null flies from oxidative stress, suggesting that the genetic and pharmacological inhibition of PDH may be a novel treatment strategy for PD associated with DJ-1 dysfunction.

Purpose: The aim of this research was to identify the mediating effect of sleep quality on the relationship between job stress and stress response of shift-working nurses. Methods: The participants in this study were 150 nurses who had more than 6 months of shift-working experience. A survey was conducted from May to June 2017 in a hospital in Gyeonggi-do, South Korea. The data were collected through self-report questionnaires. The collected data were analyzed using SAS 9.4 program. The analysis was based on Baron and Kenny's model to examine the mediating effects of sleep quality on the relationship between job stress and stress response of shift-working nurses. Results: In the first and second steps, job stress was identified as a significant predictor of sleep quality (β= .29, p= .001) and stress response (β = .24, p= .004). In the third step, sleep (B = .55, p< .001) was observed as a significant predictor of stress response, and the direct relationship between job stress and stress response was not significant (β= .07, p= .291). Sleep quality was found to exhibit complete mediating effect on the relationship between job stress and stress response. Conclusion: The results of this study suggest that strategies for managing the stress of shift-working nurses should include effective ways to ensure sleep quality.

Purpose: This study was performed to investigate the dietary behaviors and stress-related factors among male and female college students. Methods: A total of 405 college students (male-195, female-210) were recruited, of whom a questionnaire-based survey was conducted. The study investigated the general characteristics, health-related factors, dietary behaviors, and stress-related factors of the respondents. Results: The body mass index was significantly higher in males. The rates of underweight and overweight were significantly different between male and female respondents. The scores for workout frequency, health concerns and health condition were significantly higher in males, while the score for watching TV & playing computer games was significantly higher in females. The scores for meal regularity, frequency of breakfast consumption, and smoking were significantly higher in males. Eating problems showed a significant difference between males and females. The biggest source of stress was social factors, followed by college study and individual factors and the most experienced stress-induced symptom was anxiety, followed by headache and stomachache. The most popular way to overcome stress was taking a rest, followed by drinking & smoking and outdoor activity. The most preferred food under stressful conditions were alcohol or beverages, followed by hot & spicy food and sweet food, which showed a significant difference between males and females. Conclusion: These results indicate that stress affects dietary behaviors, drinking, smoking, and health status. Stress not only changes dietary behaviors, but is also related to health status. Therefore, it is necessary to develop appropriate programs for emotional stability and stress relief targeting college students which provide continuous nutrition education focused on desirable dietary behaviors and nutritional aspects.

It is well known that irritable bowel syndrome (IBS) is related to psychological distress. However, only a few studies have investigated the relationship between IBS and various dimensions of psychological distress. This study aimed to evaluate the prevalence of IBS and its relationship with anxiety, depression, and stress in young female college students. A cross-sectional study was conducted using a self-report structured questionnaire with 673 female college students. IBS was diagnosed based on the Rome III criteria. For the evaluation of psychological distress on the IBS, we investigated Hospital Anxiety and Depression Scale (HADS) and Global Assessment of Recent Stress (GARS). The prevalence of IBS was 27.9%. In the univariate analysis, the anxiety, depression, and stress scores were significantly associated with IBS (P<0.001, P=0.001, and P<0.001, respectively). Multivariate analysis showed that anxiety (OR=1.07, 95% CI=1.01~1.15, P=0.032) and stress scores (OR=1.23, 95% CI=1.19~1.27, P<0.001) were independently correlated with the IBS. Among the subtypes of IBS, IBS with predominant constipation was the most common, and the anxiety, depression, and stress scores did not significantly differ between the subtypes. Our results suggest that anxiety and stress are closely related to IBS. Managing psychological distress should be considered in the treatment of IBS in young female college students.

Fatigue tests and numerical analysis were carried out to evaluate the fatigue performance at the U-rib to deck welded joint in steel box girder. Twenty specimens were tested corresponding to different penetration rates (80 and 100%) under fatigue bending load, and the fatigue strength was investigated based on hot spot stress (HSS) method. The detailed stress distribution at U-rib to deck welded joint was analyzed by the finite element method, as well as the stress intensity factor of weld root. The test results show that the specimens with fully penetration rate have longer crack propagation life due to the welding geometry, resulting in higher fatigue failure strength. The classification of FAT-90 is reasonable for evaluating fatigue strength by HSS method. The penetration rate has effect on crack propagation angle near the surface, and the 1-mm stress below weld toe and root approves to be more suitable for fatigue stress assessment, because of its high sensitivity to weld geometry than HSS.

The purpose of this study is to provide basic data for career guidance to cosmetology students by examining the effects of job stress on career decisions and job preparation behaviors. Overall 214 parts were empirically analyzed as final samples. Collected data and statistical processing are based on SPSS ver. Analysis was performed using the 21.0 program. An analysis of the effect of job stress on career decision showed that employment anxiety (β= .206, p<.05), job anxiety(β=.824, p<.05), and anxiety in career search(β=.118, p<.05) showed a statistically significant effect(+). However, employment concerns(β=-.312, p<.001) in career determination and employment concerns(β=-.223, p<.01) in career search are statistically significant parts(-). An analysis of the effect of employment stress on employment preparation behavior found that employment anxiety(β=.364, p<.05) has a statistically significant effect(+) on information use preparation, It was found that the statistically significant part(-) affects employment anxiety(β=-.188, p<.01). The study found that the more anxious cosmetology students are about employment, the more they plan and explore career options, and make information-based preparations for employment. Through this research, we hope that there will be lively discussions among cosmetology students on career adaptability, life satisfaction, and employment anxiety.
