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.

본 연구는 노인을 대상으로 스트레스가 생활만족도에 미치는 영향과 이들 관계에서 여가활동 참여의 매개 효과를 검증하고자 하였다. 본 연구 결과는 다음과 같다. 첫째, 노인의 스트레스 중 가족 스트레스, 경제문제 스트레스, 건강문제 스트레스는 생활만족도에 유의한 부(-)적 영향을 미쳤다. 둘째, 노인의 스트레스 중 가족 스트레스, 경제문제 스트레스, 건강문제 스트레스는 여가활동 참여에 유의한 부(-)적 영향을 미쳤다. 셋째, 여가활동 참여는 생활 만족도에 유의한 정(+)적 영향을 미쳤다. 넷째, 여가활동 참여는 노년기 스트레스와 생활만족도의 영향 관계에서 유의한 매개효과가 있는 것으로 나타났다. 본 연구결과를 통해 여가활동 참여는 노인의 스트레스와 생활만족도의 영향 관계를 매개하는 것으로 나타나 대처자원으로서 유의미성을 확인할 수 있었다. 따라서 노인의 여가활동 참여는 스트레스에 대한 부정적 영향을 완화하여 노인들의 생활만족도를 높이는 중재방안으로 활용이 가능함에 의의를 둔다.

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.

Purpose: This study investigated knowledge, attitudes, and nursing stress related to life-sustaining treatment among oncology nurses. Methods: A descriptive study design was used. Data were collected through a survey from April 1 to May 31, 2022. The participants were 132 nurses working in the oncology ward of a tertiary hospital in Seoul. Data were analyzed using the SPSS 25.0 program with descriptive statics, the independent t-test, analysis of variance, and Pearson correlation coefficients. Results: The average scores for knowledge, attitudes, and nursing stress related to life-sustaining treatment were 14.42, 3.29, and 3.96, respectively. Significant differences in knowledge about life-sustaining treatment were observed based on clinical experience (P=0.029) and education about life-sustaining treatment (P=0.044). Attitudes toward life-sustaining treatment varied significantly with education about life-sustaining treatment (P=0.014), while stress levels differed significantly across working units (P=0.004). A positive correlation was found between the dilemma of extending or stopping life-sustaining treatment (a subdomain of nursing stress) and attitudes toward life-sustaining treatment (r=0.260, P=0.003). Conclusion: There was no significant correlation between the nursing stress experienced by oncology nurses and their knowledge and attitudes toward life-sustaining treatment. However, a more positive experience with life-sustaining treatment education was associated with higher stress levels related to the dilemma of extending or stopping life-sustaining treatment. Therefore, it is crucial to develop strategies to manage this dilemma and reduce stress in the field.

본 연구는 간호대학생들의 생활스트레스, 우울, 자아탄력성 및 대학생활적응 정도를 파악하고 이들간의 상관관계를 확인하여 대학생활적응에 융복합적 영향을 미치는 요인을 분석하였다. 자료수집을 위해 2015년 12월 5일부터 2016년 2월 8일까지 G시에 위치한 대학생 252명을 대상으로 생활스트레스, 우울, 자아탄력성, 대학생활적응에 대한 자료를 수집하여 분석하였다. 연구결과 생활스트레스는 동아리활동과 성적수준에 차이가 있었고, 우울은 친한친구에 따라, 자아탄력성은 전공만족도에 따라 차이가 있었으며, 대학생활적응은 동아리 활동 경험과, 성적에 따라 차이가 있었다. 또한 대학생활적응은 생활스트레스와 부적인 상관관계가 있는 것으로 나타났고, 자아탄력성은 대학생활적응에 정적 상관관계를 나타냈다. 대학생활적응에 영향을 주는 요인은 생활스트레스와 자아탄력성으로 연구모형의 설명력은 32.9. %였다. 본 연구를 통해 간호대학생의 대학생활적응을 향상시키기 위해서는 적극적인 생활스트레스 완화법과 자아탄력성 향상을 위한 융복합 프로그램 개발이 필요하다고 본다.

Most of the accelerated life tests deal with tests that use only one accelerating variable and no other explanatory variables. Frequently, however, there is a test to use more than one accelerating or other experimental variables, such as, for examples, a test of capacitors at higher than usual conditions of temperature and voltage, a test of circuit boards at higher than usual conditions of temperature, humidity and voltage. A accelerated life test is extended to M-level stress accelerated life test with k-stress variables. The optimal design for Weibull distribution is studied with k-stress variables.
