The purpose of this study was to identify the relationship between multi-cultural family husbands' stress related to their wife and their psychological abuse based on the Stress theory of Lazarus et al. Data from 271 subjects that answered to all questions regarding the subjects' social demographic characteristics, and the husbands' stress related to their wife and their psychological abuse of their wife in statistical analyses. To analyze the data, a study model was set using multi-cultural family husbands' stress related to their wife as an independent variable and their psychological abuse of their wife as a dependent variable and the goodness-of-fit of the model for the data and the relationship between the variables were reviewed using a structural equation model. According to the results, the goodness-of-fit index of the model satisfied the statistical acceptable standard with CFI=0.909 and RMSEA=0.057. The relationship between the variables indicated that multi-cultural family husbands' stress related to their wife had significant effects on their psychological abuse of their wife. This result indicates the necessity of intervention for management of the husbands' stress in order to prevent multi-cultural family husbands' psychological abuse of their wife.

The purpose of this study was to analyze mediating effect of resilience and daily spiritual experiences in the relationship of stress situations and subjective well-being of Christian college students. The subjects of this study were 157 Christian college students in a certain University which is located in Seoul, and mediating effect were analyzed through structural equation model. As a result of the analysis, first, there was a significant negative correlation between perceived stress and subject well-being. Second, resilience and spiritual experience had a full mediating effect on the relationship of perceived stress and subjective well-being. Third, in the relationship of perceived stress and subjective well-being, indirect effect through resilience has a greater mediating effect than spiritual daily experience. Implications of these results were concluded that spiritual daily experience of Christian college students is a significant variable in terms of stress and happiness. Apart from spiritual experience, however, resilience also could be a very important variable that mediates stress and happiness for Christian college students. In addition, suggestions for future research were discussed.

The levels of psychosocial stresses of dental hygienist were analyzed to reveal the various factors related to them. The self-administered questionnaires were performed, to 276 dental hygienist in Daejeon City. Univariate analysis and multiple regression were performed with survey results, in which a degree of psychosocial stress was dependent variable and others were independent variable. 1. In terms of various levels of psychosocial stress according to the higher level of stress was found in the group of lower age, unmarried, and without spare times for hobby activities, the group with shorter-term job career, lower salary, and stress was found in the group who think that their job is considered as low position or their job is not high position in society or their prospect about job is discouraging, the group without regularly exercise, without regularly eating habits, in the group with higher level of job demand, lower job autonomy, and lower social support from colleagues in work than their respective counterparts. 2. Concerning correlation between psychosocial stress and various factors, while level of stress was negatively correlated with age, job career, salary, socioeconomic status of oneself, socioeconomic status of dental hygienist, future status of dental hygienist, job autonomy, social support from superiors, social support from colleagues, social support, but it was positively correlated with job demand. 3. Multiple regression revealed that the factors which influence on psychosocial stress included hobby activities, sleeping hours, job demand, which has explanatory powers of 29.9%. Therefore, to reduce of stress of dental hygienists, it is required to develop an effective strategy that institutional support for improvement of job environments and research for them be revitalized.

This study focuses on immigrant women who are married to Korean men and who live in a multicultural family situation in Gyeonggi-do. These women experience acculturative stress and marital conflict and this study aims to determine how social support seeks to mediate the effects of those stressors. The women in this study participated in activities and received services from one of Gyeonggi-do Province's civic organizations, religious organizations, or social service organizations, such as the Social Welfare Agency and the Multicultural Family Support Center. In order to verify the study's hypothesis, the researchers used the following statistical analytical methods : t-test, two-way ANOVA and multi-regression analysis. Analysis of the study's results showed that the highest degree of marital conflict was found in the sub-zones and variables that were personal. Those variable were : the difference in mindset and values (personal domain), economic problems (communal living area), a child's upbringing and education issues (third party area), and the participant's sex life (in the marital relationship). The hypothesis was tested using the research model validation and the results are summarized as follows. First, in order to analyze the relationship between the marriage migration females' acculturative stress and the impact of that stress on marriage conflict, the hierarchical regression analysis was used. It identified that a direct correlation existed between acculturative stress and marriage conflict; where a higher degree of acculturative stress was present, a higher degree of marriage conflict was found. Second, the study found a statistical significance in the correlation and relationship (${\beta}$=.208, p<0.05) between the acculturative stress of the marriage migration female and material support. In other words, the material support can be seen as having a moderating effect on the acculturative stress, which is the independent variable, and the marital conflict, which is the dependent variable.

Stress concentration mainly occurs near holes and notches. Then local stress is larger than nominal stress. It is necessary that stress concentration phenomena are studied because it can act as a cause of fracture of material. In order to analyze fracture of material including holes, stress concentration factor and stress distribution must be studied more carefully. In this paper the stress concentration and distribution of a slotted plate is examined. Hardened 7:3 brass plate with 4 different slots including a circular hole is used. And ratios of slot length to its root radius are 1, 2, 3, 24, 4. The stress distribution is measured by using strain gages attached to the plate with variable width. And obtained experimental data are adjusted by using calibrated gage factor.

MEMS structures Generally have been fabricated using surface-machining, but the interface failure between silicon substrate and evaporated thin film frequently takes place due to difference of linear coefficient of thermal expansion. Therefore this paper studied the effect of the residual stress caused by variable external loads. This study did not analyzed accurate quantity of the residual stress but trend for the effect of residual stress. Several specimens were fabricated using other material(Al, Au and Cu) and thermal load was applied. The residual stress was measured by nano-indentation using AFM. The results showed the existence of the residual stress due to thermal load. The indentation area of the thermal loaded thin film reduced about 3.5% comparing with the virgin thin film caused by residual stress. The finite element analysis results are similar to indentation test.

In this paper, the important novelty and the defining a physical phenomenon of the resent research is the development of nonlocal stress and strain parameters on the porous sandwich beam with functionally graded materials in the top and bottom face sheets.Also, various beam models including Euler-Bernoulli, Reddy and the generalized formulation of two-variable beam theories are obtained in this research. According to a nonlocal strain elasticity theory, the strain at a reference point in the body is dependent not only on the stress state at that point, but also on the stress state at all of the points throughout the body. Thus, the nonlocal stress-strain elasticity theory is defined that can be actual at micro/nano scales. It can be seen that the critical buckling load and transverse deflection of sandwich beam by considering both nonlocal stress-strain parameters is higher than the nonlocal stress parameter. On the other hands, it is noted that by considering the nonlocal stress-strain parameters simultaneously becomes the actual case.

The thermal stress intensity factors (TSIF's) for the cusp cracks such as hypocycloid crack, symmetric airfoil crack and symmetric lip crack are determined by using Bogdanoff's complex variable approaches in plane thermoplasticity. The results are expressed in terms of the periodic functions of the direction of uniform heat flow. The TSIF's are shown to be sensitive to both the direction of uniform heat flow and be thermal boundary conditions. It is also shown that Fourence's solutions for an insulated circular hole and Sih's solutions for an insulated Griffith crack are derived from the results of the stress and displacement fields for the hypocycloid crack and the TSIF's for the various cusp cracks, respectively.
