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.

본 연구는 간호대학생의 생활스트레스와 우울과의 관련성을 파악하고자 실시한 서술적 조사연구이다. 간호대학생 311명을 대상으로 2017년 11월 20일부터 12월 5일까지 자료수집 하였으며, 분석은 SPSS 20.0 통계프로그램을 이용하여 다중선형회귀분석을 실시하였다. 연구결과, 일반적 특성과 건강관련특성 중 대학생활만족도에서 생활스트레스와 우울과의 차이가 있었다. 생활스트레스는 학업문제가 가장 높았으며, 우울수준은 16.52이었다. 상관분석결과, 생활스트레스의 모든 영역에서 우울과 유의한 양의 상관관계로 나타났다. 생활스트레스가 우울에 미치는 영향에서는 친구관계와 가치관 문제에서 유의한 차이가 있었으며, 설명력은 36.2%이었다. 결론적으로 간호대학생의 생활스트레스가 우울에 미치는 영향에 대한 결과를 바탕으로 생활스트레스 감소를 위한 중재프로그램의 개발과 간호대학생의 생활스트레스로 작용될 수 있는 다양한 예측요인 규명에 대한 후속연구의 필요성을 제안한다.

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.

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.

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.
