This paper presents accelerated life tests for Type I censoring data under probabilistic stresses. Probabilistic stress, $S_j$, is the random variable for stress influenced by test environments, test equipments, sampling devices and use conditions. The hazard rate, ,$theta_j$, is the random variable of environments and the function of probabilistic stress. Also it is assumed that the general stress distribution is uniform, the life distribution for the given hazard rate, $\theta$, is exponential and inverse power law model holds. In this paper, we obtained maximum likelihood estimators of model parameters and the mean life in use stress condition.

This descriptive research study was conducted to identify the connection between life stress and depression in nursing college students. The data was collected targeting 311 students at colleges of nursing from November 20, 2017 to December 5, 2017, and analyzed through the multiple linear regression analysis method using the SPSS 20.0 statistics program. The results of this study found that there was a difference between life stress and depression in relation to the college life satisfaction among general and health-related characteristics. The level of life stress was the highest in academic problems; and the level of depression was 16.52. According to the results of correlation analysis, all the domains of life stress showed a significantly positive correlation with depression. When it comes to the effects of life stress on depression, there was a significant difference in the relationship with friends and views of value, and the level of explanatory power was 36.2%. In conclusion, this study suggests the necessity of developing intervention programs to reduce life stress and conducting the follow-up studies which are designed to establish various predictors that may act as life stress in college nursing students, based on the results of the effects of life stress on depression in nursing college students.

Objectives: The purpose of the study is to investigate the influence of self-control on stress management and oral health related quality of life in high school students. Methods: A self-reported questionnaire was completed by 422 high school students in Ulsan from December 1, 2014 to February 20, 2015. The study instrument consisted of stress and self-control. The stress instrument included 17 items modified by Kim and Lee. The self-control instrument was modified by Kim and had 20 items. Pearson's correlation analysis was conducted to analyze the relationship between stress, self-control and oral health related quality of life. Regression analysis was used to analyze the effect of the stress on oral heal related quality of life. Hierarchical regression analysis was done to analyze the control effect of self-control in the relationship between the stress and oral health related quality of life. Results: The higher stress level resulted in the lower oral heal related quality of life. The higher self-control maintained the higher oral health related quality of life. The higher long term pursuit of satisfaction led to higher oral health related quality of life. The immediate suppression of satisfaction had a positive influence on the higher oral health related quality of life. Conclusions: There were significant correlations in self-control on stress management and oral health related quality of life.

To data were analyzed by frequency, t-test, ANOVA, correlation and a hierarchical multiple regression analysis as suggested by Baron and Kenny(1986) using PASW statistics 18.0. From the analyses, there was a negative relationship between life stress and adaptation to college life but a positive relationship between health promoting lifestyle and adaptation to college life. There was a partial mediating effect of health promoting lifestyle between life stress and adaptation to college life.

Objectives : This study was to investigate the level of health risk behavior, athletes stress, quality of life(WHOQOL-BREF) and oral health related quality of life(OHIP-14) and the clinical factors influencing quality of life in athletes Methods : Data were obtained from a cross-sectional survey of 202 university athletes. Data was obtained by means of questionnaire from October 11 to October 15, 2010. Health risk behaviors(Q-F index and smoking), athletes stress, WHOQOL-BREF and OHIP-14 were measured. The data was analysed with t-test, one-way ANOVA, Pearson correlation coefficient and multiple regression using the SPSS program. Results : The prevalence of alcohol drinking, smoking were 84.2% and 37.9%, respectively. Alcohol drinking and cigarette consumption were not related to quality of life though there were the negative correlation between athletes stress and quality of life. Powerful predictors of quality of life were athletes stress, OHIP-14 and perceived health for athletes. Conclusions : Based on the findings, quality of life has a significantly impact on athletes stress, OHIP-14 and perceived health. These results suggest that the implementation of health promotion program should be considered which was decreased athletes stress and was increased level of oral health and perceived health in athletes.

Purpose: The purpose of this research was to examine the degree of care stress and the quality of life of grandmothers caring for their grandchildren while mother was employed. Method: A convenience sample of 107 grandmothers were measured for grandmother's care stress using a revised for of the PSI/SF and the quality of life tool by Andrew and Weinert. Descriptive statistics, t-test, and Pearson correlation coeffcients were used to analyze the data using SPSS/PC 10.0 Results: The results found that grandmothers' care stress was high according to their age and religion. Their quality of life was low according to their age, their present health status, income and sleep pattern. Their subjective care stress was a sense of social isolation, burden of caring for grandchildren, health problems, and conflict with adult children. Care stress and quality of life were found to be negatively correlated. This result was statistically significant. Conclusion: In conclusion, it was found that the care stress was high and affected quality of life. From this study it is proposed that there is a need to develop programs which consider grandmother' techniques in child care and health care to improve their quality of life. Ultimately, a good care environment for children will be good for the children's growth and development.

This study investigates the effect of gender role attitude and work family balance on life stress for married career women. We also explore the mediating effect of marital intimacy on the relation between gender role attitude, work family balance, and life stress. The subjects were married women from the five year data of the Korean Longitudinal Survey of Women and Family (KLoWF). Data was analyzed by descriptive statistics, Pearson correlation, structural equational models, and Sobel test with SPSS software ver. 23.0, and Amos software ver. 23.0. The findings are as follows. First, gender role attitude had a direct effect on life stress, but work family balance had no significant effect on life stress. Second, marital intimacy mediated between gender role attitude, work family balance, and life stress. In conclusion, the results can be used as basic data to prevent life stress in married career women and increase marital intimacy.

The primary purpose of this study is to construct a path model in which shows how the background variables, retirement-related variables, and perceptions of stress in retirement influence life satisfaction among retirees. Data from a probability sample of retirees who are not employed as a full - time (n of retirees=261)are used. The social stress model, developed by House (1974) and George (1980), presented and tested in this research focuses on the perspective of the retirees. The major findings are: 1. The retirees perceive relatively high levels of stress in retirement. 2. Levels of living standard, health status, and locus of control are significant factors in differentiating the degrees of perceived stress in retirement and life satisfaction. 3. Concerning the retirement variables, the previous job satisfaction, plans and preparatins for leisure activities and financial arrangement contribute to differentiate the degrees of perceived stress in retirement and life satisfaction. 4. While health status, locus of control, and the perceptions of stress in retirement influence directly on life satisfaction, age, education, income, and activity level influence indirectly through the retirement - related variables and the perceptions of stress in retirement on life satisfaction. The significant impact of the perceptions of stress in retirement upon life satisfaction receives strong support.
