  • In fracture problems, stress intensity factors obtained theoretically and experimentally have been effectively utilized in the analytical evolution of the cracks effect. The effect of surface crack of a cylindrical and a hollow cylindrical bar is investigated, as well as the effect of the thickness of a hollow cylindrical bar and inclined crack of a hollow cylinder subjected to torsion moment. In this study, stress intensity factor Km of mode III which expresses the stress state in the neighborhood of a crack tip is used. stress analysis was conducted on the inside of hollow cylinder inthe axial direction of three dimensional crack tip subjected to torsion moment by combining the caustics method and the stress freezing method.

  • Most of ferrous b.c.c weld materials may experience martensitic transformation during rapid cooling after welding. And it is well known that volume expansion due to phase transformation could influence in the case of welding of high tensile strength steels on the relaxation of welding residual stress. To apply this effect practically, it is a prerequisite to establish a numerical model which is able to estimate the effect of phase transformation on residual stress relaxation quantitatively. In this study, we investigated the effect of phase transformation on the relaxation of welding residual stress through experiment. And three-dimensional thermal elastic-plastic FEM analysis is conducted to compare the effect of phase transformation on the relaxation of welding residual stress in high strength steels(POSTEN60, POSTEN80) with analytical results which is not considering the effect of phase transformation on residual stress relaxation. According to the results, the extents of welding residual stress relaxation due to phase transformation in the case of welding of POSTEN60, POSTEN80 are 0.85 $\sigma$/$\sigma$$\sub$Y0/, 0.75$\sigma$/$\sigma$$\sub$Y0/, respectively.

  • Objectives: The purpose of this study was to examine the mediating effect of self-esteem on the relationship between academic stress and depression in foreign students in Korea. Methods: The subjects of this study were 343 foreign students enrolled in universities and graduate schools in Daegu and Gyeongbuk area, and data were collected by conducting a questionnaire survey using the internet. The collected data was analyzed using SPSS 23.0 and PROCESS macro Model No 4. Results: The results were as follows. First, academic stress of foreign students increased the level of depression statistically significantly. Second, academic stress significantly reduced the self-esteem of foreign students. Third, the self-esteem of foreign students partially mediated the effect of academic stress on depression (p<0.05). In other words, it suggests that academic stress lowered self-esteem, and that the lowered self-esteem had an effect on the increase in depression.

  • Objectives : The purpose of this study was to identify the mediation effect of a positive stress coping strategy between clinical practice stress and clinical practice satisfaction in nursing students. Methods : In this study, data was collected from 248 nursing students at K University in South Korea from October of 2015 to November of 2015. The collected data was analyzed using the SPSS 22.0 Statistics Program. Results : Clinical practice stress and a positive stress coping strategy were significant predictors of clinical practice satisfaction (${\beta}$=.442, p<.001). The explanatory power of the measure of clinical practice satisfaction was increased to 29.3% (p<.001) with solely clinical practice stress, and it reached 44.2% (p<.001) when a positive stress coping strategy was reflected. The results of this study confirmed that a positive stress coping strategy has a mediation effect on clinical practice stress and clinical practice satisfaction levels. Conclusions : It is necessary to develop a program to take advantage of positive stress coping skills so that nursing college students can smoothly overcome stress during their clinical training and thus improve their clinical practice experience.

The research method was self_report questionnaire was completed by 383 careworkers at care homes for the elderly in the Seoul metropolitan area between December 10th, 2018 to January 11th, 2019. and date analyzed using the IBM AMOS 22.0 program. As a result, First, positive psychology capital has been shown to have a negative effect on job stress. Second, positive psychology capital has been shown to have a positive effect on the enthusiasm of care workers. Third, job stress has been shown to have a negative effect on the enthusiasm of care workers. Fourth, in the relationship between positive psychology capital and care worker's enthusiasm, job stress revealed that it had a partial mediated effect. This means that positive psychological capital of the care workers has a negative effect on job stress, and the job stress, which has been negatively effected by positive psychological capital, has a positive mediated effect on the enthusiasm of the worker.

  • The purpose of this study was to examine effect of locus of control and self-efficacy on stress of selected dental hygiene students. This study provides basic data to develop a method to reduce stress. The students of A women's college in Kyungi province majoring in dental hygiene were asked to answer the locus of control scale, self-efficacy scale, and stress level. As a result, this study concluded the following findings: 1. Locus of control scale was 8.77 and it meant the students used internal control. Self-efficacy scale was beyond median. In stress level category, mean of stress was 2.32, stress with friends was 2.05, stress with money was 2.33, stress with course in life was 2.29, stress with family members was 2.24, stress with study was 2.95. 2. Stress had negative relations with locus of control and self-efficacy. There was a positive relation between locus of control and self-efficacy. 3. Effect of self-efficacy on stress was significantly negative but effect of locus of control on stress was insignificant. In subscale, effect of self-efficacy and locus of control on stress with study was insignificant. 4. Indirect effect of locus of control on stress was statistically significant. The students with internal locus of control showed high self-efficacy and the students with high self-efficacy showed low stress level. In conclusion, educators should make an effort to reduce stress of students and understand the factors related to stress.
