Purpose: The purpose of this study was to identify the health promotion, stress and the quality of life and relationship between those factors in patients with genital neoplasms. Method: Data of 151 subjects with genital neoplasms were collected from August 15 to October 12, 2009 at out-patient clinic in one general hospital in Daegu. Results: The mean score of health promotion of the subjects was 1.49 (${\pm}0.53$), stress of gynecologic cancer was 1.36 (${\pm}0.76$) and the quality of life of the subjects was 2.38 (${\pm}0.59$). There was a negative correlation between the quality of life and stress (r=-.482, p<.001), and positive correlation between the quality of life and health promotion (r=.442, p<.001) in the subjects. Conclusion: This study showed correlations between the health promotion, stress and the quality of life of patients with genital neoplasms. The quality of life of the patients with genital neoplasms was low when their stress was high. In contrast, their quality of life was high when the score of health promotion was high. Considering the research findings, it is necessary to develop a health promotion program for patients with genital neoplasms to strengthen their health promotion behaviors.

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.

Translation is a costly, but inevitable, cell maintenance process. To reduce unnecessary ATP consumption in cells, a fine-tuning mechanism is needed for both ribosome biogenesis and translation. Previous studies have suggested that the ribosome functions as a hub for many cellular signals such as ribotoxic stress response, mammalian target of rapamycin (mTOR), and ribosomal S6 kinase (RSK) signaling. Therefore, we investigated the relationship between ribosomes and mitogen-activated protein kinase (MAPK) activation under ribotoxic stress conditions and found that the activation of c-Jun N-terminal kinases (JNKs) was suppressed by ribosomal protein knockdown but that of p38 was not. In addition, we found that JNK activation is driven by the association of inactive JNK in the 80S monosomes rather than the polysomes. Overall, these data suggest that the activation of JNKs by ribotoxic stress is attributable to 80S monosomes. These 80S monosomes are active ribosomes that are ready to initiate protein translation, rather than polysomes that are already acting ribosomes involved in translation elongation.

Purpose: This study was done to explore the level of life stress, depression, and suicidal ideation and to identify the associated factors of suicidal ideation (SI) among college nursing students. Method: The design of this study was a descriptive survey design using a convenience sampling. Data collection was done using self-questionnaire from 124 students in 2 universities located in Gyeonggi and Chungnam provinces. The collected data were analyzed using descriptive statistics, ANOVA, t-test, Pearson correlation coefficients, and hierarchical multiple regression. Results: Study participants reported low level of SI, depression, and life stress ($44.45{\pm}19.21$, $8.40{\pm}5.94$, $40.65{\pm}32.17$). The 53% of variance in SI was significantly explained by life stress related value (${\beta}=.41$, p<.001), life stress related to interpersonal relationship with family (${\beta}=.19$, p=.014), life stress related to interpersonal relationship with friends (${\beta}=.34$, p<.001), and depression (${\beta}=.36$, p<.001). Conclusions: The results indicate that to decrease the SI in these students, an active interest in the students is needed to lower stress levels in interpersonal relationships with family and friends, in life stress related to value, and for relief of depression. Suicide prevention programs specific to the level of life stress and depression need to be developed for nursing students.

The method for fatigue life prediction of ball bearing is proposed applying the algorithm of contact fatigue prediction based on stress analysis. In order to do this, a series of simulation such as initial surface stress analysis, EHL analysis, subsurface stress analysis and fatigue analysis are conducted from the loading at each ball location calculated for a bearing subjected to external bearing load and contact shape function. And uniaxial fatigue tests are performed to obtain fatigue parameter of AISI 52100 steel. It was found that since stress is usually higher at the inner raceway contact than at the outer raceway contact, fatigue failure occurs on the inner raceway first. When the fatigue life calculated in the stress-based method are compared with $L_{50}$ life of L-P model, Crossland criterion for the radial load increment is similar to $L_{50}$ life and Dang Van criterion for the axial load increment is similar. In the case of EHL contact. there is no difference of fatigue life between dry contact and EHL contact, when maximum Hertz pressure exceeds 2.5GPa.

Objectives: As COVID-19 drags on, university students experience more stress and feel more anxious about their studies and career plans. Against the backdrop, this study aims to analyze the moderating effect of family health on the relationship between the spread of COVID-19 and the quality of life in university students. Methods: In order to achieve the purpose of this study, the results of an online survey performed with 216 university students in cities K and D were analyzed using frequency analysis, factor analysis, correlation analysis, regression analysis, and moderating effect analysis. Results: It was found that COVID-19 stress had a significant negative effect on the quality of life in university students, while family health showed a significant positive effect. In addition, the moderating effect of family health was statistically significant on the relationship between COVID-19 stress and the quality of life in university students. Conclusions: This study found that family health plays an essential role as a safety net in reducing stress and improve the quality of life in university students amid the social crisis of the COVID-19 pandemic. In this regard, it is required to develop various programs for communication with parents, including parent-child communication techniques.

Purpose: This correlational study was undertaken to examine the relationship among daily life stress, self-efficacy, hardiness, and health behavior of university students. Methods: Two hundred sixty five university students were gathered from the undergraduate classes. Data were collected through self-reported question- naires which included daily life stress scale, self-efficacy scales, hardiness scales, and health behavior scales. Results: The daily life stress level had a maximum score of 4 with a mean score of 2.09 and the mean score of health behavior was 2.56. A negative correlation exists among daily life stress, self-efficacy, and health behavior. The self-efficacy is positively correlated with the health behavior. According to the hardiness factor, health behavior is positively correlated with hardiness. In the subareas, health behavior is positively correlated with control, commitment, and challenge. The self- efficacy factor was positively correlated with challenge. Conclusions: In conclusion, based onthe results of this study, both self-efficacy and hardiness are useful concepts in reducing the stress level and in increasing the health promoting behavior. Therefore, it is necessary to develop a program based on both self-efficacy and hardiness.

Purpose: This study was conducted to determine the mediator effect of social support in the association between stress for college life and depression among nursing students. Methods: The participants of the study were 201 university students in A and C cities. Self-report questionnaires were used to measure the variables. In the data analysis, the SPSSWIN 25.0 program was utilized for descriptive statistics, Pearson's correlation, Sobel test and multiple regression analysis. Results: Mean scores of stress for college life, depression and social support were 2.56, 4.12 and 0.61, respectively. Stress for college life and depression showed a significant positive correlation (r=.60, p<.001), while depression and social support showed a significant negative correlation (r=-.46, p<.001). Lastly, stress for college life and social support showed a significant negative correlation (r=-.55, p<.001). The analysis of the mediator effect of social support in the association between stress for college life and depression showed that social support had a significant mediator effect. Conclusion: Among nursing students, social support may be a mediator in the association between stress for college life and depression. Therefore, strategies for nursing intervention to improve social support should be developed for nursing students.
