The purpose of this study was to investigate the effect of type of values on coping stress through communication ability. The data for the study were collected from February 1 to 15, 2019, and the participants were collected through online questionnaires in the twenties who voluntarily participated in the study. The final data used in this study were 324. The research method was cross - sectional questionnaire survey. The analysis was done using SPSS 18.0, descriptive statistics, Pearson correlation, multiple regression and median effect analysis. A total of 324 people participated in the study, 38% of men and 62% of women were female. The results of this study showed that the collectivism values were positively correlated with individualism values (r = .224, p<0.01), emotional stress coping style (r = .266, p <), And emotion - centered stress coping was correlated with problem - oriented stress coping (r = .369, p <0.01). Those who had a collectivist value had a significant influence on the type of problem - centered stress coping(${\beta}=.271$, p<0.01), and the communication ability showed a perfect mediating effect($R^2=.310$,${\beta}=.113$, p>0.05). According to the results of this study, stress coping in the twenties suggests a program that fosters individualized communication ability.

Most cracks in the structure occur under mixed mode loadings and those propagation depend on the stress ratio very much. So, it is necessary to study the fatigue behavior under mixed mode loading as stress ratio changes. In this paper, fatigue crack propagation behavior was investigated respectively at stress ratio 0.1, 0.3, 0.5, 0.7 and we change loading application angle to $0^{\circ},\;30^{\circ},\;60^{\circ}$ to apply various loading. mode. The mode I and II stress intensity factors of CTS specimen used in this study were calculated by displacement extrapolation method using FEM(ABAQUS). Using both the study through the experiment and the theoretical study through FEM analysis, we studied the relation between crack propagation rate and stress intensity factor range at each loading mode due to the variation of stress ratio. Also, when the crack propagated under given stress condition and given loading mode condition, we studied what the dominant factors of the crack propagation rate were at each case.

This study checks if the PITR (Person in the Rain) test can diagnose the stress caused by school-work for middle school students, in that the PITR responses correlates with the degree of stress. The subjects in the study are 483 middle school thirdgraders from 8 middle schools in Daegu city. Research tools used are an Academic Stress Scale and a PITR test. For data analysis is adopted with t-test and Chi-square test. The results from the study are as follows. First, the stress of middle students scores 2.47/4 that means that the school stress is average, and there is no gender difference in scores. Second, PITR test shows that boys draw more rain than girls, straight rain with stronger wind, hide face more, no good facial expressions more often than girls. Girls on the contrary show more stable lines, bigger puddles, place protections more appropriately. Third, those with higher academic stress use more unstable strokes, less number of or insufficient direct protections than those with less academic stress, and draw indirect protection such as umbrellas before rain or clouds. The study concludes that a PITR test can be useful in diagnosing the academic stress of middle school students.

Purpose: This study was to construct a structural equational model for explaining and predicting job stress of intensive care unit (ICU) nurses based on the Integrated model of stress of Ivancevich and Matteson (1980). Methods: The subjects of this study were 220 nurses at ICU. The data were collected from August 5 to 30, 2013 through self-reporting questionnaire survey. Results: According to the hypothetical model of this study, perceived nursing practice environment, perceived role conflict, perceived transformational leadership and perceived self-esteem showed statistically significant effects on job stress of ICU nurses directly. Professional self-concept indirectly affect job stress of ICU nurses. In conclusion, job stress of ICU nurses was directly influenced by nursing practice environment, role conflict, transformational leadership and self-esteem. Professional self-concept of the relationships among variables did not have a direct impact on job stress. Conclusion: Based on the results of this study, it is needed to develop stress management measures and programs considering these variables in order to adequately manage job stress of ICU nurses.

The purpose of this study is to examine whether there is a mediating effect of hopelessness the relationship between perceived stress and suicidal ideation in college students. For this study, a survey was conducted on perceived stress, suicidal ideation, and mental health, self-esteem, problem drinking, and stress among 103 college studentsin Gyeonggi do. The results of this study are as follows. It was found that COVID-19 correlated with perceived stress, hopelessness, and suicidal ideation of college students. The hopelessness completely mediated between perceived stress and suicidal thoughts of college students, which is consistent with previous studies. This study is meaningful in that it confirmed relationship between the perceived stress, hopelessness, and suicidal ideations in college students due to COVID-19, reflecting the new situation of the times. Coronavirus will worsen people's mental health disorders and cause new stress-related disorders. Therefore, mental health researchers, clinicians, and people working in trauma-related fields should find ways to reduce the incidence of coronavirus-related trauma stress and prevent its effects. It is necessary to expand the psychological vaccine program to improve the resilience of the public. Since there are individual differences in resilience, it is necessary to strengthen the psychological vaccine program for each subject considering resilience.

Objective: The purpose of this study was to analyze the causal relationship between parenting knowledge, parenting stress, and parenting behavior of mothers with infants and to confirm the longitudinal mediating effect of parenting stress in the relationship between parenting knowledge and parenting behavior. Methods: This study used data collected through the Panel Study on Korean Children from 2008 to 2010 and the participants were 1,444 mothers with infants. The data were analyzed through technical statistics, correlations and multivariate potential growth models using SPSS 28.0 and AMOS 26.0. Results: Parenting knowledge and parenting stress of mothers gradually increased, and positive parenting behavior gradually decreased. Having a lot of parenting knowledge reduced mother's parenting stress. Mother's parenting stress reduced positive parenting behavior, and as parenting stress increased, positive parenting behavior decreased significantly. However, the relationship between parenting knowledge and parenting behavior was not significant. In addition, the mediating effect of parenting stress was confirmed in the relationship between parenting knowledge and parenting behavior of mothers. Conclusion/Implications: The results of this study suggest the need to reduce parenting stress and promote positive parenting behavior along with the systematization of parent education programs in order for mothers with infants to acquire parenting knowledge.

The final goal of this study is to develop the core technologies applicable to the design, operation and maintenance of welds in nuclear structures. This study includes predicting microstructure changes and residual stress for welded parts of nuclear power plant components. Furthermore, researches are performed on evaluating fatigue, corrosion, and hydrogen induced cracking and finally constructs systematically integrated evaluation system for structural integrity of nuclear welded structures. In this study, metallurgical and mechanical approaches have been effectively coordinated considering real welding phenomena in the fields of welds properties such as microstructure, composition and residual stress, and in the fields of damage evaluations such as fatigue, corrosion, fatigue crack propagation, and stress corrosion cracking. Evaluation techniques tried in this study can be much economical and effective in that it uses theoretical/semi-empirical but includes many additional parameters that can be introduced in real phenomena such as phase transformation, strength mismatch and residual stress. It is clear that residual stress makes great contribution to fatigue and stress corrosion cracking. Therefore the mitigation techniques have been approached by reducing the residual stress of selected parts resulting in successful conclusions.

Overconsolidated clays have a different stress history according to the deposit environment. The stress history is classified into (i) rotation angle of stress path, (ii) overconsolidation ratio, and (iii) magnitude of length of recent stress path. Stress-strain behaviour of overconsolidated clays strongly depends on these stress history. In this study a series of drained stress path tests were carried out. Test results indicated that stress-strain behaviour of overconsolidated clay(focused on strain rate) depends on OCR and length of recent stress path, especially rotation angle.
