The purpose of this study is to find out the stress causes of the primary students in Korea, through the three major methods, life event score, multiple regression about stress causes and G.H.Q. path-diagram. A survey was made of 889 students who were selected among students of six primary schools in seoul and Ka-pyeng, from Sep. 28 to Oct. 2. 1992. The results of this study are summarized as follows : 1. Life event score Among the children's life events, (deaths of family) (degrade of school record) (the increase of absence days) (divorce of parents) (trouble with relationship) are high ranking in life event score. Besides, (scolded by teacher and parents) (beginning of extracurricular work) are spread stress causes. In conclusion, these stress causes are shown by two aspects, home, school, and so children are under stress circumstance in both places. These stress causes vary with area and sex. 2. Multiple regression about stress causes and G.H.Q. This study analysed how a stress caused by home life affects the children's health of mind and body. The most influential factors are , and these factors vary with area and sex. 3. Path-diagram This study proved that socio-psychological school environment raises children to secede from school, and this secession that operates as a stress cause affects children's health of mind and body. This serial process is analysed by path analysis, and made out a path-diagram. In conclusion, as expected socio-psychological,school environment affects the children's health of mind and body. This is shown by two aspects : positive, negative. This stress causes vary with area and sex.

Background: Workplace violence was recognized to be social problems that might impact the health status and the job satisfaction of employee in hospitals. This study investigated the current status of violence and job stress among hospital employees working at administration and discharging department. Methods: The study subjects were 213 administrative employees working at 20 general hospitals. Data were collected by self-administered questionnaire that included information such as demographics, job-related characteristics, experience of violence, and job stress. The violence was classified as verbal violence, physical threat, and physical violence occurred by patients and caregivers. Analysis of variance, t-tests, correlation analysis, and multiple linear regression analysis were performed to examine the associated factors with job stress. Results: The levels of verbal violence, physical threat, and physical violence were $1.64{\pm}1.08$, $0.54{\pm}0.67$, and $0.04{\pm}0.17$, respectively. The score of job stress was $2.74{\pm}0.50$ and it was associated with age, existence of spouse, drinking frequency, subjective health status, disease history, night-time treatment, and public health administration career in simple analysis. In multiple linear regression analysis, the level of verbal violence experience was significantly associated with job stress (B=0.09, p=0.001). Also physical threats (B=0.18, p<0.001) and physical violence (B=0.48, p=0.008) showed positive association with job stress. Conclusion: This study attempted to examine the association between experience of violence and job stress in administrative employees at medical institutions. Levels of violence showed positive correlation with the job stress. Environment improvement to protect employee from violence and management of employees who experienced workplace violence are needed to reduce the job stress.

Purpose: This study aimed to compare and analyze the job stress of nurses with and without in COVID-19-related work. Methods: A structured self-reported questionnaire survey was conducted to assess job stress. The extent of job stress was compared between nurses with COVID-19 (COVID-19 group) and those without such experience (non-COVID-19 group). Multiple regression analysis was performed to identify the factors influencing job stress. Results: Job stress was higher in the COVID-19 group compared to the non-COVID-19 group (t=2.54, p=.12). In sub-categorical comparison, stress driven by a taxing work environment, relationship conflict, and work schedule was higher in the COVID-19 group than the non-COVID-19 group. Multiple regression analysis revealed the job stress was higher among nurses with COVID-19-related work experience than that of non-experienced nurses. The factors affecting job stress of nurses with COVID-19-related work experience included emergency room work, providing nursing assistant for COVID-patients, and caring for these patients. Conclusion: Since COVID-19-related work experience is a major factor that affects nurses' job stress, it is imperative to provide various support measures for nursing assistants such as providing a break from working in an environment with high risk of infection, adjusting work schedules, resolving conflicts between personnel, and securing support.

Injury caused by reactive oxygen species (ROS), known as oxidative stress, is one of the major damaging factors in plants exposed to environmental stress. Chloroplasts are specially sensitive to damage by ROS because electrons that escape from the photosynthetic electron transfer system are able to react with relatively high concentration of $O_2$ in chloroplasts. To cope with oxidative stress, plants have evolved an efficient ROS-scavenging enzymes such as superoxide dismutase (SOD) and ascorbate peroxidase (APX), and low molecular weight antioxidants including ascorbate, glutathione and phenolic compounds. To maintain the productivity of plants under the stress condition, it is possible to fortify the antioxidative mechanisms in the chloroplasts by manipulating the antioxidation genes. A powerful gene expression system with an appropriate promoter is key requisite for excellent stress-tolerant plants. We developed a strong oxidative stress-inducible peroxidase (SWPA2) promoter from cultured cells of sweetpotato (Ipomoea batatas) as an industrial platform technology to develop transgenic plants with enhanced tolerance to environmental stress. Recently, in order to develop transgenic sweetpotato (tv. Yulmi) and potato (Solanum tuberosum L. cv. Atlantic and Superior) plants with enhanced tolerance to multiple stress, the genes of both CuZnSOD and APX were expressed in chloroplasts under the control of an SWPA2 promoter (referred to SSA plants). As expected, SSA sweetpotato and potato plants showed enhanced tolerance to methyl viologen-mediated oxidative stress. In addition, SSA plants showed enhanced tolerance to multiple stresses such as temperature stress, drought and sulphur dioxide. Our results strongly suggested that the rational manipulation of antioxidative mechanism in chloroplasts will be applicable to the development of all plant species with enhanced tolerance to multiple environmental stresses to contribute in solving the global food and environmental problems in the 21st century.

Purpose: The Purpose of this study was to examine the degree of obesity stress and analyze factors having an effect on obesity stress among college women. Method: The subjects were 347 female students from a university in J City. Data were collected using a self-report questionnaire for general characteristics, health-related characteristics, and current and preferred somatotype. Obesity stress was measured using 10 items developed by Cho (1996) based on Body Attitudes questionnaire (BAQ) of Ben-Tovim and Walker (1991). The survey was conducted from September 4 to September 7, 2007. Data were analyzed by t-test, ANOVA, Scheffe test, Spearman's rank correlation test, and stepwise multiple regression using SPSS 14.0. Results: The average score of obesity stress was $2.78{\pm}0.90$ out of 5.00. Stepwise multiple regression analysis showed that the major factors that affect obesity stress of female college students were perceived body shape, disagreement between current and preferred somatotype, history of weight control, body mass index (BMI), and perceived health status, and these factors explained 38.4% of obesity stress. Conclusion: Subjective judgment in the perception of or preference for body shape was the most important factor affecting obesity stress in female college students. Therefore, a plan is necessary to mitigate obesity stress and evaluate individually subjects who perceive themselves to be fat or want to be thinner than the current somatotype. And consultation and constant management are needed to help the high risk group (experience of weight control, BMI ${\geq}23kg/m^2$, not good health status).

Objective : The purpose of this study was to investigate the effect of preceptors' transformational leadership on job stress and clinical performance among new graduate nurses. Methods : The study subjects were 180 new nurses in three University Hospitals. General characteristics, leadership, job stress and clinical performance were collected using self-reported questionnaires. Transformational leadership consisted of charisma, intellectual stimulation and individual consideration. T-test, ANOVA, pearson correlation and multiple regression analysis were performed to access the effect of leadership on job stress and clinical performance. Results : Of 180 subjects, 94.4% were female. The mean scores of transformational leadership, charisma, intellectual stimulation and individual consideration were $3.9{\pm}.46$, $3.9{\pm}.46$, $3.9{\pm}.57$ and $4.0{\pm}.58$, respectively. In multiple regression analysis, overall transformational leadership(${\beta}$=.154, p=.006) and charisma(${\beta}$=.388, p=.008) significantly increased the job stress. On the other hand, individual consideration significantly decreased the job stress (${\beta}$=-.671, p=.048) and increased the clinical performance(${\beta}$=2.472, p=.024). Conclusions : Charisma of preceptors was associated with the increase of job stress, and individual consideration was associated with the decrease of job stress and improvement of clinical performance. Therefore, the preceptors' leadership focusing on individual consideration rather than charisma may reduce job stress and improve clinical performance in the University hospital organization.

Purpose: The purpose of this study was to analyze the effects of self-efficacy and collective-efficacy on job stress in the nursing staff. Method: This study surveyed 160 nurses in three general hospitals in the Seoul and Gyung-gi province for two months starting in September 2004. The questionnaire consisted of 54 questions about job stress, 10 questions about self-efficacy, and 7 questions about collective-efficacy. The answers were on a scale rating of 5. The answer sheets were analyzed with descriptive statistics, the t-test, ANOVA, the tukey test, the Pearson correlation coefficients and stepwise multiple regression using SAS version 8.2. Result: The average job stress rating of the nurses was 3.11. The average self-efficacy and the average collective-efficacy were 3.41 and 3.39, respectively. The age, working department, income level, shift-work and hospital have influence on job stress. Efficacies such that self-efficacy and collective-efficacy have influence on job stress. The much efficacy makes the less job stress. The stepwise multiple regression revealed that the significant predictor of job stress was working department and hospital. Conclusion: This study showed that collective-efficacy as well as self-efficacy reduces job stress, so nursing intervention methods should promote collective-efficacy. The collective-efficacy improvement program should be developed to improve job performance, to improve cohesion of nursing units, and to improve satisfaction on the job. The next research could be to develop collective-efficacy improvement programs for nursing units.

Purpose: The aims of this study were to describe the levels of personal coping resources, perceived organizational supports, and job stress, and to examine factors that affect job stress in hospital-based home care nurse practitioners. Methods: A cross-sectional survey was conducted. Data were collected from 170 subjects with a structured questionnaire from April to July, 2016 and analyzed using descriptive statistics, t-tests, One-way ANOVA, Pearson's correlation, and multiple regressions. Results: The means for personal coping resources, perceived organizational supports, and job stress were $3.7{\pm}0.43$, $3.4{\pm}0.55$, and $3.4{\pm}0.55$ out of 5, respectively. Personal coping resources and perceived organizational supports were significantly correlated. However, both had no associations with job stress. In the multiple regression analysis, the experiences of home care nursing and hospital location were found to be predictors of job stress. Both personal coping resources and perceived organizational supports were not statistically significant predictors of job stress. Conclusions: It is necessary to carry out organization-based educational programs and support systems aimed at enhancing personal abilities to cope with stress at work. Additionally, further studies are needed to identify other hospital-related characteristics that can lead to job stress in home care nurse practitioners.
