Purpose: This study investigated the relationship between degree of stress and quality of life in mothers of children with cerebral palsy. Methods: This study's subjects were 77 mothers of children under 10 years of age with cerebral palsy. The instrument is a self-administered, structured, written questionnaire. The tool that measured the degree of stress was created by modifying the questionnaire by Park (2004). Quality of life for all mothers with cerebral palsy was evaluated by the ShortForm-36 Health Questionnaire. To verify the effects on degree of stress and quality of life arising from general characteristics, t-tests and ANOVAs were conducted. The correlation between degree of stress and quality of life was analyzed via Pearson's correlation analysis. Results: The mothers' degree of stress was rated as 2.69 out of 5; their quality of life was rated as 53.07 out of 100. There was a significant negative correlation between quality of life and the age of cerebral palsy and positive correlations between quality of life and mother's age, background, and family income. Degree of stress among mothers has a positive correlation with quality of life. Conclusion: This study provides basic data about the relationship between degree of stress and quality of life in mothers of children with cerebral palsy.

Purpose: Nursing stress on life-sustaining treatment of nurses is a significant contributing factor to nursing care performance and patient care outcomes. We need to investigate the factors associated with nursing stress on life-sustaining treatment in hospital settings. The purpose of this descriptive study was to examine the relationship of role perception of life-sustaining treatment and good death perception with nursing stress on life-sustaining treatment among nurses in hospital settings. Methods: Using a cross-sectional study design, we recruited nurses at a hospital located in a metropolitan city in Korea. The nurses completed structured questionnaire questions which were composed of well-validated questionnaires. Descriptive statistics and hierarchical multiple regression model were utilized for data analysis. Results: A total of 205 nurses participated in the study (female 93.2%; aged 20~29 years 63.0%; single status 78.5%). In the hierarchical multiple regression model, there was a significant positive relationship between role perception of life-sustaining treatment and nursing stress on life-sustaining treatment (β=.27, p<.001). Higher education level and working at a ward setting were also significantly related to nursing stress on life-sustaining treatment (β=.13, p<.046 for education level; β=.22, p=.001 for work setting). However, there was no relationship between good death perception and nursing stress on life-sustaining treatment. Conclusion: Education programs to reduce nursing stress on life-sustaining treatment are needed to develop for nurses who have higher role perception of life-sustaining treatment with higher education level working at ward settings in hospitals.

The study is to investigate how much middle-aged male worker's life stress affect their psychological well-being. The subject group was 223 male workers aged from 40 to 59 with a wife and children. The results are as follows: 1) the middle-aged male workers perceive an economic life stress as a most stressful problem, and mostly use a 'direct-positive' coping behavior(CB) type to settle the stress among 4 stress CB types. 2) Economic life and marital stress, 'indirect-active' and 'direct-active' CB give deep effects on their life satisfaction. 3) The effecting factors on their depression are work stress, marital stress, health stress, a 'direct-passive', an 'indirect-active', an 'indirect-passive' CB and their income. In order to increase their life satisfaction and to decrease their depression, concludingly, it is most significant for them to have a strong marital relationship and actively cope with life stress.

The purpose of this study is to examine the types of the stress and coping behaviors perceived by mothers of children with disabilities, and to investigate factors affecting their life satisfaction. For this study, we surveyed 239 mothers living in the city. The results are as follows: First, we can categorize the stress into parental stress, economic stress, child developmental stress, physical stress, and emotional stress. Second, we can classify the coping behaviors into active efforts, avoidance, and emotional diversion. Lastly, life satisfaction of mothers of children with disabilities tends to depend on such factors as emotional stress, husband's support, parental stress, emotional diversion coping, economic stress, school- children, and their education.

Purpose: This study was conducted to determine the impacts of perceived stress and self-compassion on the quality of life of nursing students. Methods: Data were collected from 180 nursing students between 11 October and 26 October 2018 from a college in A city. A total of 157 questionnaires were analyzed using descriptive statistics, t-tests, a one-way ANOVA, Pearson correlation, and stepwise multiple regression. Results: The findings show that perceived stress had a significant negative correlation with quality of life (r=-.73, p<.001). However, self-compassion showed a significant positive correlation with quality of life (r=.66, p<.001). The factors influencing quality of life included perceived stress, self-compassion, state of health, and satisfaction with school life, with perceived stress being the most influential factor (β=-.42), followed by self-compassion (β=.30), which together had an explanatory power of 64.0%. Moreover, there was a mediating effect of self-compassion in the relationship between perceived stress and quality of life. Conclusion: The results of this study indicate that nursing college students should search for ways to reduce their perceived stress as well as increase self-compassion with meditation programs in order to improve their quality of life.

This study was performed to investigate stress levels, dietary behaviors and food choices, and their correlations in college students. General characteristic stress scores, using a stress test, and the dietary behaviors and food choices of subjects under stress were measured in 358 subjects (185 males and 173 female). The mean total stress scores of the male and female students were $67.91{\pm}44.85$ and $85.62{\pm}48.91$, respectively. Female students were more stressed than males in relation to family, value, future, friends, and study related factors. There were gender differences in the food intake and frequency of eating sweet things when under stress. Stress increased the food intake and frequency of eating sweet things in female students. Especially, stress factors, such as value, economic, future, friends and study problems increased the food intake of female students. Female students preferred sweet tasting items; whereas, male students preferred hot tasting items when under stress. These results show the effect of life stresses on the dietary behaviors and food choices of college students. Stress not only increased energy consumption in certain individuals, but also changed their food choices. Therefore, education with regard to nutrition is necessary if college students are to practice good eating habits for the correct management of life stresses.

Accelerated life tests (ALTs) are extensively used to determine the reliability of a product in a short period of time. Test units are subject to elevated stresses which yield quick failures. ALT can be carried out using constant-stress, step-stress, progressive-stress, cyclic-stress or random-stress loading and their various combinations. An ALT with linearly increasing stress is ramp-stress test. Much of the previous work on planning ALTs has focused on constant-stress, step-stress, ramp-stress schemes and their various combinations where the stress is generally increased. This paper presents an optimal design of ramp soak-stress ALT model which is based on the principle of Thermal cycling. Thermal cycling involves applying high and low temperatures repeatedly over time. The optimal plan consists in finding out relevant experimental variables, namely, stress rates and stress rate change points, by minimizing variance of reliability function with pre-specified mission time under normal operating conditions. The Burr type XII life distribution and time-censored data have been used for the purpose. Burr type XII life distribution has been found appropriate for accelerated life testing experiments. The method developed has been explained using a numerical example and sensitivity analysis carried out.

Ceramides are the major sphingolipid metabolites involved in cell survival and apoptosis. When HepG2 hepatoma cells were treated with celecoxib, the expression of the genes in de novo sphingolipid biosynthesis and sphingomyelinase pathway was upregulated and cellular ceramide was elevated. In addition, celecoxib induced endoplasmic reticulum (ER) stress in a time-dependent manner. SPTLC2, a subunit of serine palmitoyltransferase, was overexpressed by adenovirus. Adenoviral overexpression of SPTLC2 (AdSPTLC2) decreased cell viability of HEK293 and HepG2 cells. In addition, AdSPTLC2 induced apoptosis via the caspase-dependent apoptotic pathway and elevated cellular ceramide, sphingoid bases, and dihydroceramide. However, overexpression of SPTLC2 did not induce ER stress. Collectively, celecoxib activates de novo sphingolipid biosynthesis and the combined effects of elevated ceramide and transcriptional activation of ER stress induce apoptosis. However, activation of de novo sphingolipid biosynthesis does not activate ER stress in hepatoma cells and is distinct from the celecoxib-mediated activation of ER stress.
