The purpose of this study was to examine the stressors of students in high school. Demographic data such as educational level of parents, mother's employment, family type, level of living, and students' growing place and their sex. The data were analyzed by t-test, one-way ANOVA, and Ducan Multiple Range Test. Students' stressors showed partial sex differences in each sub-category. Females feel more stress greater physical and mental health, sibiling relationship, whereas males feel more stress greater girl and boy friends. Students' stressors showed partially significant differences in only home environment and family stressors according to demographic variables. That is, home environment stressors differed in educational level of parents, mother's employment, family type, level of living, and students' growing place except mother's employment. Family stressors showed partially significant differnces in only family type and level of living.

Purpose: This study is conducted to evaluate the job stressors for dental technicians in Ulsan city. Methods: The Korean standard job stressors assessment tool developed by Korea Occupational Safety and Health Agency (KOSHA) was used to compare the survey result with Korean reference value. The questionnaire on the social, demographic and job characteristics of dental technicians was also used to find the factors affecting to job stressors by using multiple linear regression analysis. Results: A total of 155 questionnaire was collected from 2010 to 2011. Among the eight fields of stressors, the physical environment (men 50.0, women; 58.3) and job demands (men 57.1, women 57.1) were higher than the median value of the Korean Workers. By multiple linear regression analysis, the significant factors to the physical environment were the satisfaction degree of indoor odor, number of employee, duty and working hours. In terms of the job demand, duty, working hours, age, and the satisfaction to the efficiency of space utilization were significantly associated to the score of job demand. Conclusion: Based on these results, it is necessary to manage appropriate workload, control indoor odor and design an efficient work space for prevention of job stress of dental technicians.

Purpose - In hotel industry, quality of leader-member exchange(LMX) relationship is very critical, because it impacts on the employee's work attitude and behaviors. Thus, this research examines the effect of LMX on employee loyalty in the context of hotel business and identifies mediating roles of work stressors, work role performance in the relationship between LMX and employee loyalty. This research suggests the guidelines for how hotel leaders should manage their employees and build employee loyalty that improve management and business performance. Research design, data, and methodology - This study tests the structural relationship between LMX, work stressors, work role performance, and employee loyalty. Work role performance divide into three sub-dimensions such as individual task proficiency, individual task adaptivity, and individual task proactivity. In order to examine the purposes of this research, research model and hypotheses were developed. All constructs were measured with multiple items developed and tested in the previous studies. The data were collected from 113 franchise hotel employees and were analyzed using SPSS 22.0 and SmartPLS 3 program. Result - The findings of this research are as follows. First, leader-member exchange(LMX) have significant positive impacts on work stressors, work role performance, and employee loyalty. Second, work stressors have significant negative impacts on work role performance and employee loyalty. Third, work role performance has significant positive impact on employee loyalty. Conclusions - The outcomes of this research indicate that hotel leaders should focus on the dyadic relationship with their employees how to improve employee productivity through LMX relationship. In turn, the quality of this relationship influences employees's work attitudes and behaviors. As a result of increasing job demands in hotel business which relies heavily on human resources, the hotel leader must find ways to prevent or reduce stressors and associated strains. If hotel employees perceive the high quality of LMX relationship, they improve their work role performance which influences loyalty. Therefore, the hotel leaders should develop monetary or non-monetary reward system for the employees and, make an efforts to have unique social exchange relationships with employees.

Kelp forests and the many vital ecosystem services they provide are threatened as the severity of climate change and other anthropogenic stressors continues to mount. Particularly in the North Pacific, sea surface temperature is warming and glacial melt is decreasing salinity. This study explored the resiliency of early life-history stages of these foundation species through a factorial laboratory experiment. The effects of rising sea surface temperature under low salinity conditions on kelp spore settlement and initial gametophyte growth in Eualaria fistulosa, Nereocystis luetkeana, and Saccharina latissima were investigated. Decreased settlement and growth were observed in these species at elevated temperatures and at low salinity. Eualaria fistulosa spores and gametophytes were the most negatively impacted, compared to the more widely distributed N. luetkeana and S. latissima. These results suggest that N. luetkeana and S. latissima could potentially outperform E. fistulosa under projected conditions. However, despite decreased performance among all species, our findings indicate that these species are largely resilient to temperature changes when exposed to a low salinity, even when the temperature changes are immediate and extreme. By exploring how early life-history stages of several key kelp species are impacted by dual stressors, this research enhances our understanding of how kelp forests will respond to projected and extreme changes in temperature when already stressed by low salinity.

Background: Exploratory study to investigate whether co-exposure to physical wrist stressors and chemicals is associated with carpal tunnel syndrome (CTS) in French male farmers and agricultural workers. Methods: Cross-sectional study of 711 men aged 30-65 years and working as either farmers or agricultural workers in 2009-2010 within a cohort covered by the French Agricultural Workers' and Farmers' Mutual Benefit Fund. CTS and exposure to physical wrist stressors and chemicals were assessed using a self-administered questionnaire. Associations between CTS and personal/medical factors, exposure to physical wrist stressors, exposure to chemicals, and co-exposure to physical wrist stressors and chemicals were studied using multivariate logistic regression models. Results: Forty-four men {5.6% [95% confidence interval (CI) 4.0-7.7]} reported that they had suffered from unilateral/bilateral CTS during the last 12 months. CTS was associated with age, current smoking [odds ratio (OR) = 2.1 (1.0-4.5)], and exposure to physical wrist stressors [OR = 2.6 (1.1-5.9)]. An association was found between CTS and co-exposure to physical wrist stressors and chemicals [OR = 3.3 (0.8-14.3), p = 0.044] in comparison with the no-exposure group. Conclusions: This exploratory study shows an association of CTS with exposure to biomechanical wrist stressors in male farmers and agricultural workers and suggests an association of CTS with co-exposure to physical wrist stressors and chemicals. Owing to the limitations of the study, this result must be confirmed by a prospective study with objective assessments of the outcome and exposure before drawing conclusions on the possible synergistic effects of mechanical stressors and chemicals on the impairment of the median nerve.

Purpose : This study was to determine the levels of environmental stressor, posttraumatic stress disorder, and quality of life in intensive care units (ICU) survivors after intensive care, and to explore the factors affecting posttraumatic stress disorder and quality of life. Methods: With a longitudinal survey design, data were collected from 116 patients who were discharged from the ICU of a university hospital. The environmental stressor, posttraumatic stress disorder, and quality of life were measured immediately following and 1 month after the ICU discharge. Results: Of all the subjects, 16.4% experienced posttraumatic stress disorder after discharge. Multiple regression analysis revealed that ICU environmental stressors, experience of ICU readmission, using psychotropic drugs and narcotic analgesics, and ICU admission after surgery or cardiac intervention accounted for 22.2% of posttraumatic stress disorder. Posttraumatic stress disorder and sedation status when entering ICU accounted for 28.3% of the quality of life 1 month after ICU discharge. Conclusion: Nursing interventions focused on ICU environmental stressors would not only reduce environmental stress but also contribute to the reduction of posttraumatic stress disorder and later improvement of quality of life.

The purpose of this study was to examine the stressors of students in high school. Demographic data such as jobs of parents, family types, levels of living (parents' monthly income) and students' school records, high school types, number of friends, religion, pocket money and their sex showed as the main causes of high school students' stress. The data was analyzed by a t-test, one-way ANOVA, and Duncan Multiple Range Test. The variable which significantly influenced the general properties was sex(p=0.001), high school type (p=0.000), number of friends (p=0.002), parents monthly income (p=0.011) and whether existence of their father or not (p=0.045). In the result (stress score), girl students (25.07) feel greater stress than boy students (20.68). High school type, an academic girls' high school (27.34) and boys' high school (25.67) showed the highest. It was indicated in the study that it is necessary to have programs that help students' stress management and improve high school type Systems.

The present study explores how the stress of online learners is related to Korean cultural norms and social expectation and presents the criteria online education should aim at when designing instructional approaches. A sample of 176 students from a Korean online university participated in a study investigating the patterns in the academic and personal stressors they face. This study also examines stressor types in relation to sample characteristics, analyzed with a categorization method developed by extant researchers on the stress faced by U.S. college students. Unlike the findings of previous studies on college student stress, this study's results reveal that nontraditional Korean online students were faced with (1) taking on the multiple roles at work and home prescribed by cultural and social norms, and (2) challenges in regulating study habits and the learning environment as adult learners. The relevant implications for the design of online learning are discussed.

Saccharomyces cerevisiae KNU5377 was examined to assay the recovering capacity against heat and other stressors. Along with a particular fermentation ability that is able to produce ethanol even at high temperature such as $40^{\circ}C$ with a comparable rate to the fermentation at $33^{\circ}C$, this strain also exhibited higher viability than a reference strain owing to its own thermotolerance that conferred the survival after the severe heat shock at $60^{\circ}C$ for 30 minutes. Furthermore, this strain showed outstanding tolerances against $H_2O_2$, ethanol and some chemical compounds. But, especially due to the thermotolerance, this strain has been suspected of other species of yeast. However, ITS (internally transcribed spacer) 1 and 2 sequencing data confirmed this strain was a typical strain of S. cerevisiae. The outstanding tolerances to various environmental stressors Indicate this S. cerevisiae KNU5377 is enough to use both as an on-site potential strain for world-wide alcohol fermentation industry and as a model strain for researches into the routes to acquire the tolerance to various stressors.
