This descriptive research study was conducted to identify the connection between life stress and depression in nursing college students. The data was collected targeting 311 students at colleges of nursing from November 20, 2017 to December 5, 2017, and analyzed through the multiple linear regression analysis method using the SPSS 20.0 statistics program. The results of this study found that there was a difference between life stress and depression in relation to the college life satisfaction among general and health-related characteristics. The level of life stress was the highest in academic problems; and the level of depression was 16.52. According to the results of correlation analysis, all the domains of life stress showed a significantly positive correlation with depression. When it comes to the effects of life stress on depression, there was a significant difference in the relationship with friends and views of value, and the level of explanatory power was 36.2%. In conclusion, this study suggests the necessity of developing intervention programs to reduce life stress and conducting the follow-up studies which are designed to establish various predictors that may act as life stress in college nursing students, based on the results of the effects of life stress on depression in nursing college students.

The purpose of this study was to explore relationship among communication with parent, self differentiation, self esteem, life stress in nursing department students. Data were collected from 305 nursing department students and analyzed using descriptive statistics, t-test, ANOVA, Bonferroni's test, Pearson's correlation coefficients and multiple regressions with the SPSS/WIN 18.0 program. Stress frequency differed according to stress importance, self differentiation, self esteem. Hierarchical multiple regression analysis showed stress importance, self differentiation, self esteem explained 38.6% of the total variance in stress frequency. The findings indicate that stress importance, self differentiation, self esteem have an influence on stress frequency. We need to develop and provide nursing intervention programs to decrease college student's stress.

The purpose of this study is to obtain basic data to be used in social welfare intervention for relieving psychological burdens caused by job stress in the eco-boomer generation that will be the center of Korean society in future, by estimating job stress change trajectories of the eco-boomer generation in the convergence era, figuring out predicting factors and examining job stress factors that individuals experience, in accordance with the degree of job stress and the changes. This is a longitudinal study using secondary data and for analysis, the Latent Growth Model(LGM) was applied to the 1st year to the 7th year Korean Welfare Panel Data. Self-esteem was one of job stress predicting factors of the eco-boomer generation. Since most of eco-boomers were students in the early measurement period, the level of job stress was low, but over time, the burden of job increased by gradation. This study has significance by providing an empirical basis for predicting factors of job stress changes of the eco-boomer generation to understand job stress in the eco-boomer generation.

The purpose of this study was to investigate the relationship between job stress and coping style in college students. Participants were 314 students in a college. Data were collected using a self administered questionnaire. The survey was conducted from May 02, 2018 to May 28, 2018. There were statistically significant correlations between personality stress, family environmental stress, academic stress, school environment stress and emotion - centered coping style among sub - variables of job stress, Job anxiety stress was significantly correlated with social support seeking and emotion - centered coping style. Since college students' emotional stress coping style is related to depressive emotional and physical health problems, it is necessary to provide a psychological treatment program for early detection and coping with psychological support services, and a mixed service such as education, lecture, and camp. In addition, it is thought that strategic action skill training (plan, method, and technology) is needed to change from emotion - centered coping style to problem - solving style.

This study was aimed to evaluate the effects of art and craft activities on anxiety and stress of stroke patients. Patients diagnosed with stroke were selected according to select the study target, 9 patients with experimental group receive art and craft activities, 9 patients with control group receive traditional occupational therapy for 30 minutes per each session 3 times a week for total 8 weeks. Art and craft activities were structured through a group of occupational therapy practitioners interview. A comparison of two groups after the intervention showed that the experimental group had a more significant on the anxiety and stress(p<.05). These result demonstrate that art and craft activities decrease anxiety and stress for stroke patients, therefore is expected to be useful in clinics.

This paper examines the blood chamber of a left ventricular assist device (LVAD) under static loading conditions and standard operating temperatures. The LVAD's walls are made of a temperature-sensitive polymer (ChronoFlex C 55D) and are covered with a titanium nitride (TiN) nano-coating (deposited by laser ablation) to improve their haemocompatibility. A loss of cohesion may be observed near the coating-substrate boundary. Therefore, a micro-scale stress-strain analysis of the multilayered blood chamber was conducted with FE (finite element) code. The multi-scale model included a macro-model of the LVAD's blood chamber and a micro-model of the TiN coating. The theories of non-linear elasticity and elasto-plasticity were applied. The formulated problems were solved with a finite element method. The micro-scale problem was solved for a representative volume element (RVE). This micro-model accounted for the residual stress, a material model of the TiN coating, the stress results under loading pressures, the thickness of the TiN coating and the wave parameters of the TiN surface. The numerical results (displacements and strains) were experimentally validated using digital image correlation (DIC) during static blood pressure deformations. The maximum strain and stress were determined at static pressure steps in a macro-scale FE simulation. The strain and stress were also computed at the same loading conditions in a micro-scale FE simulation.

Fire ranks high among the potential risks faced by most buildings and structures. A full understanding of temperature effects on fiber reinforced concrete is still lacking. This investigation focuses on the study of the residual compressive strength, stress strain behavior and surface cracking of structural polypropylene fiber-reinforced concrete subjected to temperatures up to $300^{\circ}C$. A total of 48 cubes was cast with different fiber dosages and tested under compression after exposing to different temperatures. Concrete cubes with varying macro (structural) fiber dosages were exposed to different temperatures and tested to observe the stress-strain behavior. Digital image correlation, an advanced non-contacting method was used for measuring the strain. Trends in the relative residual strengths with respect to different fiber dosages indicate an improvement up to 15 % in the ultimate compressive strengths at all exposure temperatures. The stress-strain curves show an improvement in post peak behavior with increasing fiber dosage at all exposure temperatures considered in this study.

The purpose of this study is to find out the difference of sense of self-efficacy and stress encountering strategy of university students under the stress situation depending on the smart-phone user group (addiction group, general user group). For this purpose, the study issues are established as follows. First, it has analyzed what is the correlation of smart-phone addiction, sense of self-efficacy, and stress encountering strategy. Second, it has studied if there is any difference of sense of self-efficacy and stress encountering strategy for the smart-phone user group. In order to verify such study issues, For 1,670 university students in the Chungcheong area, smart-phone addiction scale, sense of self-efficacy scale, and stress encountering method scale were administered. Looking into the study result, first, as a result of the relativity analysis, it displayed the correlation of preference of test difficulty, self-control efficacy and important negative from the smart-phone addiction and sense of self-efficacy. In addition, all sub-variables of smart-phone addiction and avoidance orientation from the stress encountering strategy displayed the important positive correlation, and from the smart-phone addiction, the virtual world orientation and pursuit of social-support displayed the important negative correlations, and all sub-variables (interference with ordinary living, virtual world striving direction, withdrawal, resistance) of smart-phone addiction and problem solving-orientation displayed the negative correlation. Second, as a result of verification for the difference of the smart-phone addiction group and general use group following the sense of self-efficacy, the general use group is shown to have higher self-control efficacy sense than the addiction group. And third, as a result of verifying the difference of stress encountering following the smart-phone addiction group and general use group, the addiction group is shown to be lower than the general use group in terms of social support pursuit and problem solution orientation with the avoidance orientation shown to be higher. This type of result is expected to provide the base data when developing the smart-phone addiction preventive education program by finding out in details for the characteristics of smart-phone addiction group for university students.
