This paper considers a nonparametric estimation of lifetime distribution for ramp stress tests with stress bound under intermittent inspection. The test items are inspected only at specified time points an⊂1 so the collected observations are grouped data. Under the cumulative exposure model, two nonparametric estimation methods of estimating the lifetime distribution at use condition stress are proposed for the situation which the time transformation function relating stress to lifetime is a type of the inverse power law. Each of items is initially put on test under ramp stress and then survivors are put on test under constant stress, where all failures in the Inspection interval are assumed to occur at the midi)oint or the endpoint of that interval. Two proposed estimators of quantile from grouped data consisting of the number of items failed in each inspection interval are numerically compared with the maximum likelihood estimator(MLE) based on Weibull distribution.

The purpose of this study was to analyze the impact of parental resources and parenting stress on parenting efficacy in low-income families Furthermore, in order to verify whether parental resources function as a resilience factor, a structural model was established to assess the suitability and influence of the variables. A total of 603 parents of children and adolescents between the ages of 9-18 were selected from the data from Children and Adolescents Comprehensive Status Research (2009) by the Ministry for Health, Welfare and Family Affairs. For the analyses, SPSS WIN 18.0 and AMOS 18.0 were utilized. The major results were as follows: First, the suitability of the model was confirmed with variables presenting a satisfying fit. Second, parental resources had a negative effect on parenting stress and a positive effect on parenting efficacy. Third, parenting stress had a negative effect on parenting efficacy. Finally, a test of the structural equation model supports the hypothesis that parental resources have a significant direct effect as well as an indirect effect through parenting stress on parenting efficacy. The implications for further studies and practice were discussed.

This study was conducted to investigate whether dietary chlorella intake could have an effect on antioxidative capacity in rats oxidatively stressed with cadmium (Cd). Sprague-Dawley rats fed dietary chlorella (0, 5, and 10%) for 4 weeks after induction of oxidative stress by exposing to Cd (200 ppm) for 8 weeks. After the oxidative stress applied, plasma and liver malondialdehyde concentrations and xanthine oxidase activities were decreased in 5% chlorella fed group compared to chlorella free group. Although liver heme oxygenase-1 protein expression was not affected by chlorella, the enzyme activity was improved in 5% chlorella fed group. Erythrocyte superoxide dismutase activity and hepatic metallothionein concentration were increased in 5% chlorella fed group. However, 10% chlorella intake had no effect on the improvement of oxidative stress-related enzymes and proteins. These findings suggest that, after induction of oxidative stress with Cd, 5% chlorella intake might improve antioxidative capacity against oxidative stress.

The purpose of this study was to investigate the relationship between perceived stress. self respect & stress response of high school students to provide the basic data for nursing intervention programs in order to manage stress in students. The subject of this study was 279 students (male; 179. female; 100) in high school. Seoul. Korea. during the period from July. 2000. The instruments for this study was a stress management scale developed by Park Young Ae(l996), a self respect scale by Coopersmith (1967) and a physical. emotional response scale to stress by Ro, Jae Hak(1991). The data was analyzed by descriptive statistics, t-test. Pearson correlation coefficient. The results of analysis were as follows: 1) Total perceived stress between males & females didn't show a significant difference but subgroups of stress, 'parent' & 'friend' showed significant differences. Male students were experienced in 'parent' stress than females and female students were more experienced in 'friend' stress than males. 2) A significant negative correlation was revealed between perceived stress & self respect. 3) A significant positive correlation was revealed between self respect & stress response. The result of this study lead us to the suggestion that for high school students. the development of stress management methods for improving self respect should be expanded.
