Purpose: The purpose of this study was to investigate life stress, social support, and antepartum depression among Southeast Asian immigrant women married to Korean men. Methods: Ninety-three subjects were recruited from local women's clinics and multicultural family support centers in D City. The instruments used were the life stress scale, social support scale, and K-EPDS. All the instruments were translated into their corresponding mother languages (Vietnamese, Cambodian, and Philippine) and notarized. Results: The item mean scores of life stress and social support were 2.65 and 3.17, respectively, on a 5-point Likert scale. The mean score of antepartum depression was 10.16, indicating that they were generally in a depressive state. A positive correlation was observed between life stress and antepartum depression (r=.59, p<.001). Social support was negatively correlated with life stress (r=-.42, p<.001) and antepartum depression (r=-.39, p<.001). The best predictors for antepartum depression were life stress, marital satisfaction, and emotional support, and they explained 43% of the variance. Conclusion: Antepartum depression in Southeast Asian immigrant brides was significantly associated with life stress as well as lack of emotional support. Emotional support may reduce their life stress and antepartum depression.

Purpose: The purpose of the study was to identify levels of hope, self-esteem, and quality of life, and to find correlations among these variables in people with spinal cord injury. Methods: This study was a cross-sectional descriptive survey. The data were collected by survey interview in 2010 from 120 people with spinal cord injury living in the community. To measure hope, self-esteem and quality of life, the Dispositional Hope Scale, Self-Esteem Scale, and World Health Organization's Quality of Life Instrument were utilized respectively. The data were analyzed using descriptive statistics, t-test, ANOVA, Pearson's correlation and stepwise multiple regression analysis using SPSS version 12.0. Results: Mean score of hope was 2.56 and that of self-esteem was 3.23. Mean score of quality of life was 3.01. Statistically significant relationships were found between quality of life and hope (r=.73, p<.001), and between quality of life and self-esteem (r=.67, p<.001). Multiple regression analyses showed that hope and self-esteem were statistically significant in predicting quality of life with the explanatory power of 59.1%. Conclusion: The results of this study indicate that nursing interventions fostering hope and self-esteem should be integrated in developing rehabilitation programs to improve quality of life for people with spinal cord injury.

A local strain approach was applied to an external single and double grooved C-shaped specimen in order to evaluate and predict the fatigue crack initiation life by using low cycle fatigue properties. The low cycle fatigue properties were determined from the strain-controlled fatigue tests using smooth cylindrical axial specimens. Fatigue crack initiation life was evaluated by a life prediction software, FALIPS, based on the local strain approach. The fatigue life was significantly influenced by the mean stress, and SWT parameter represented the fatigue life effectively. The predicted fatigue crack initiation life was then compared to the experimental fatigue life evaluated from the C-shaped fatigue test specimens. A good correlation was found between the experimental and predicted fatigue lives within factors of 2 and 4 for the single and double grooved C-shaped specimens respectively. Also, experimental fatigue life of the double grooved specimen was 10-12 times longer than that of the single grooved specimen.

This study determined the effects of the height and the quality of the material of popular heel-up insole on mean plantar foot pressure during walking. Seven healthy college students who are studying at S university in Busan were as participants in this study. After sufficiently explaining about the research to the subjects before the experiment, mean plantar foot pressures were examined using F-Scan Pressure Measure System 5.23 for the gait with shoes inserted insole and the data were compared among the height and the quality of material of insoles. In the result, there was a difference significantly in the mean plantar foot pressure followed the height of insoles both left and right. Especially, mean plantar foot pressure in left indicated significantly lower in 3 cm and 5 cm insoles than in 0 cm and 1 cm insoles. Also mean plantar foot pressure in right showed significantly lower in 3 cm and 5 cm insoles than in 0 cm, and indicated significantly lower in 5 cm insoles than in 1 cm and 3 cm insoles. The mean plantar foot pressure followed the quality of the material of insoles were different significantly. In left, the mean plantar foot pressure of urethane poly-acetyl insole was lower significantly than urethane poly-acetyl inserted air insole, power-gel insole and jelly insole. And the mean plantar foot pressure of urethane poly-acetyl insole was lower significantly than power-gel insole and jelly insole in right. We showed that 3 cm and 5 cm insoles in the height of insoles and Urethane poly-acetyl insole in the quality of material were suitable to reduce a fatigue which is felt in plantar foot during the walking.

We consider a step-stress life testing which is devised for a two-component parallel system with considerably long life time. To describe such a system, we use an exponential distribution as the survival function. The lift distribution is assumed between the log mean life time and the stress with the cumulative exposure model. The criterion for optimality is to minimize the sum of the variances of the maximum likelihood estimators of the mean life times of each part under the normal stress.

Purpose - This study is to investigate the relationship among emotional intelligence, self-efficacy and job stress of foreign life insurance consultants focusing on the mediating effect of self-efficacy. Regarding job security, in general foreign life insurance companies in Korea have more severe working conditions in terms of required contract performance. For foreign life insurance consultants, they are assumed to need higher level of emotional intelligence and self efficacy to meet the conditions. In this study, focus is cast on these aspects. Research design, data, and methodology - Basically the research is conducted upon questionnaires responded by foreign life insurance consultants. That is, data are collected from 255 sample of insurance consultants who work for a foreign owned life insurance company. The Questionnaire measure the level of emotional intelligence, self-efficacy and job stress of insurance consultants. The data are analyzed using pearson's correlation coefficient and hierarchical multiple regression, descriptive statistics, t-test, ANOVA, Durbin-Watson test. Results - The general characteristics of respondents are gender, age, marital status, education level, income monthly, career length, change jobs no, working day per week, call no. per week, meeting no. with client per week, contract regularity, contract no. per month and cancellation contract per year. The mean of emotional intelligence is 2.63, self-efficacy is 3.44 and job stress is 2.20. Emotional intelligence is composed with mean value of self emotion appraisal(3.93), other's emotion appraisal(3.78), regulation of emotion(3.29) and use of emotion(3.52). The mean of self efficacy is composed with mean value of self-confidence(3.41), self-regulated efficacy(3.59) and preference task difficulty(3.30). The job stress is composed with mean value of job requirement(2.61), lack of job autonomy(1.99), conflict of personal relations(1.99), job instability(2.38), organizational system(2.19) and inappropriate compensation(2.07). There is a significant positive correlation between emotional intelligence and self-efficacy. The emotional intelligence and self-efficacy are significantly negative correlation with job stress. The self-efficacy is showed a mediating variable between emotional intelligence and job stress. Conclusions - To decrease job stress level, foreign life insurance company should find the factors to improve the emotional intelligence and self-efficacy of life insurance consultants, and develop appropriate plans using a mediating role of self- efficacy between emotional intelligence and job stress.
