Purpose: This study was conducted to determine the impacts of perceived stress and self-compassion on the quality of life of nursing students. Methods: Data were collected from 180 nursing students between 11 October and 26 October 2018 from a college in A city. A total of 157 questionnaires were analyzed using descriptive statistics, t-tests, a one-way ANOVA, Pearson correlation, and stepwise multiple regression. Results: The findings show that perceived stress had a significant negative correlation with quality of life (r=-.73, p<.001). However, self-compassion showed a significant positive correlation with quality of life (r=.66, p<.001). The factors influencing quality of life included perceived stress, self-compassion, state of health, and satisfaction with school life, with perceived stress being the most influential factor (β=-.42), followed by self-compassion (β=.30), which together had an explanatory power of 64.0%. Moreover, there was a mediating effect of self-compassion in the relationship between perceived stress and quality of life. Conclusion: The results of this study indicate that nursing college students should search for ways to reduce their perceived stress as well as increase self-compassion with meditation programs in order to improve their quality of life.

This study targeted college students to determine the moderating effect of immersion in the relationship among stress, satisfaction with life, and satisfaction with college life. To this end, the level of stress, satisfaction with life, satisfaction with college life, and immersion were measured in353 students attending S University. First of all, correlation analysis showed that stress had a negative correlation with immersion, satisfaction with life, and satisfaction with college life and immersion had a positive correlation with satisfaction with life and satisfaction with college life. Hierarchical regression analysis was conducted to determine the moderating effects of immersion in the relationship among stress, satisfaction with life, and satisfaction with college life. The results showed that immersion had a moderating effect on the relationship between stress and satisfaction with life, while immersion did not have a mitigating effect on the relationship between stress and satisfaction with college life. Based on these findings, this paper suggests raising the ability of immersion as a measure of intervention in handling the stress of college students and discusses the significance and limitations of this study.

A few clues about correlation between endoplasmic reticulum (ER) stress and mulberry (Morus alba) leaves were investigated in only the experimental autoimmune myocarditis and streptozotocin-induced diabetes. To investigate whether a novel extract of mulberry leaves fermented with Cordyceps militaris (EMfC) could suppress ER in fatty liver, alterations in the key parameters for ER stress response were measured in high fat diet (HFD)-induced obese C57L/6 mice treated with EMfC for 12 weeks. The area of adipocytes in the liver section were significantly decreased in the HFD+EMfC treated group as compared to the HFD+Vehicle treated group, while their level was higher in HFD+Vehicle treated group than No treated group. The level of the eukaryotic initiation factor 2 alpha ($eIF2{\alpha}$) and inositol-requiring enzyme 1 beta ($IRE1{\alpha}$) phosphorylation and CCAAT-enhancer-binding protein homologous protein (CHOP) expression were remarkably enhanced in the HFD+Vehicle treated group. However, their levels were restored in the HFD+EMfC treated group, although some differences were detected in the decrease rate. Similar recovery was observed on the ER stress-induced apoptosis. The level of Caspase-3, Bcl-2 and Bax were decreased in the HFD+EMfC and HFD+orlistat (OT) treated group compared to the HFD+Vehicle treated group. The results of the present study therefore provide first evidence that EMfC with the anti-obesity effects can be suppressed ER stress and ER stress-induced apoptosis in the hepatic steatosis of HFD-induced obesity model.

Plants are constantly exposed to a variety of abiotic stresses, such as drought, heat, cold, flood, and salinity. To survive under such unfavorable conditions, plants have evolutionarily developed their own resistant-mechanisms. For several decades, many studies have clarified specific stress response pathways of plants through various molecular and genetic studies. In particular, it was recently discovered that ubiquitin proteasome system (UPS), a regulatory mechanism for protein turn over, is greatly involved in the stress responsive pathways. In the UPS, many E3 ligases play key roles in recognizing and tethering poly-ubiquitins on target proteins for subsequent degradation by the 26S proteasome. Here we discuss the roles of RING ligases that have been defined in related to abiotic stress responses in plants.

Insects affect crop harvest yield and quality, making plant response mechanisms to insect herbivores a heavily studied topic. However, analysis of plant responses to honeybees is rare. In this study, comprehensive metabolic profiling of Arabidopsis thaliana exposed to honeybees was performed to investigate which metabolites were changed by the insect. A total of 85 metabolites-including chlorophylls, carotenoids, glucosinolates, policosanols, tocopherols, phytosterols, β-amyrin, amino acids, organic acids, sugars, and starch-were identified using high performance liquid chromatography, gas chromatography-mass spectrometry, and gas chromatography-time-of-flight mass spectrometry. The metabolite profiling analysis of Arabidopsis exposed to honeybees showed higher levels of stress-related metabolites. The levels of glucosinolates (glucoraphanin, 4-methoxyglucobrassicin), policosanols (eicosanol, docosanol, tricosanol, tetracosanol), tocopherols (β-tocopherol, γ-tocopherol), putrescine, lysine, and sugars (arabinose, fructose, glucose, mannitol, mannose, raffinose) in Arabidopsis exposed to honeybees were higher than those in unexposed Arabidopsis. Glucosinolates act as defensive compounds against herbivores; policosanols are components of plant waxes; tocopherols act as an antioxidant; and putrescine, lysine, and sugars contribute to stress regulation. Our results suggest that Arabidopsis perceives honeybees as a stress and changes its metabolites to overcome the stress. This is the first step to determining how Arabidopsis reacts to exposure to honeybees.

Purpose: The purpose of this study was to describe stress levels, stress coping methods, and college adjustment according to behavior styles in freshman nursing students. Methods: Data were collected through a structured questionnaire targeting general characteristics, behavior styles, stress levels, stress coping methods, and college adjustment, and were analyzed with descriptive statistics, ANOVA, t-tests, and Pearson correlation using the SPSS program. Results: Stress was related to perceived physical health status, satisfaction with school life, and behavior style. Problem-focused coping was related to exercise, satisfaction with school life, and behavior style. College adjustment was related to place of residence, personality, perceived physical health status, motivation for entrance, and satisfaction with school life. College adjustment had significant positive correlations with stress and problem-focused coping. The relationship between college adjustment and hopeful-thought coping had a significantly negative correlation. Conclusion: These results suggest that identifying the effects of self-understanding programs on stress management and college adjustment is required.

purpose: This study aims to understand the relationship between stress in college life, vulnerability to depression, and smartphone overuse among undergraduate students majoring in public health. Methods: The subjects of the study were 320 students who were selected through convenience sampling from the department of emergency medical technology, physical therapy, and public health and administration attending G University in Gwangju. The study was carried out from October 22 to 26, 2012. For final analysis, 266 copies were used. Statistical analysis was done using SPSS WIN 12.0. Results: Excessive use of smartphones had a negative effect on stress in college life and vulnerability to depression. The stress of college life had an effect on students' sense of value, their friends of the same sex, and job. Depressive vulnerability had an effect on a students' dependency. Conclusion: For the prevention of smartphone overuse, programs to prevent college life stress and vulnerability to depression should be developed. Counselling programs for the groups should be made available to the students.

Purpose: The purpose of this study was to identify the influencing factors on mental health related quality of life (MHRQoL) in adults across the lifespan. Methods: A total of 688 Korean adults aged 19 years and older were selected. Data were collected by personal interviews or self report using structured questionnaires. For data analysis, t-test, ANOVA, Pearson's correlation coefficients and Stepwise multiple regression were used. Results: Mental health related quality of life (MHRQoL) differed significantly according to life cycle, especially showing a lower score in the elderly than others. In addition, elderly adulthood reported the highest stress and depression. The most significant predictors of MHRQoL in young and middle aged people were stress, depression, and subjective health status. Predictors of MHQoL in the elderly were stress and religion. Conclusion: The results indicate that MHRQoL of adult is associated with stress and depression. When the programs are developed to enhance mental health in elderly adulthood, religion should be considered as well as stress.
