  • Purpose: This study was conducted to identify influence of emotional awareness, ambivalence over emotional expressiveness and emotional regulation style on nursing student adjustment. Method: One hundred and sixty nine nursing students completed the questionnaires from May to June, 2013. Data analysis was done using descriptive statistics, independent t-test, ANOVA, Pearson correlation coefficient, and multiple regression with SAS v 9.3. Results: Ambivalence over positive emotional expressiveness, motivation of application for nursing-aptitude, emotional awareness-mood labeling, avoidant/distractive style of emotion regulation, and parents-both alive were identified as factors influencing nursing student adjustment. The model explained 37% of variance in nursing student adjustment. Conclusion: The results of this study suggest that programs for promoting mood labeling and reducing ambivalence over positive emotional expressiveness and avoidant/distractive style of emotion regulation are important for college adjustment in nursing students. In addition, aptitude test for nursing applicants can be considered.

  • The objective of this study is to examine the hedging effectiveness of shrimp futures market. Hedging effectiveness is measured by OLS model based on rolling windows. Analysis data are obtained from Kansai Commodities Exchange in Osaka and are weekly data of frozen shrimp futures and cash prices in the time period from July 9, 2003, to May 9, 2007. The empirical results are summarized as follows:First, the correlation coefficients between the nearby futures price changes and the cash(16/20) price changes are very low and have range from 0.141 to 0.208 values. Second, the minimum variance hedge ratios($\hat{\beta}$) are all statistically different from 0 at the 5% level and range from 0.0477 to 0.5039 values excluding Indian shrimps(26/30). Ex post hedging effectiveness, as measured by the coefficient of determination, $R^2$, is relatively very low and range from a low of 0.4% for west-south Indian shrimps(26/30) to a high 4.3% for Vietnamese shrimps(16/20). Third, ex ante hedging effectiveness, as measured by out-of-sample hedging period, is also very low and range from a low of -4.4% for west-south Indian shrimps(21/25) to a high of 3.4% for Vietnamese shrimps(16/20). This indicates that the shrimp futures market doesn't behave as risk management instrument of shrimp spot.

  • Purpose: The purpose of this study was to explore differences in health belief by compliance level with breast self-examination (BSE) and the predictors of BSE compliance among women. Method: Using a convenience sampling method, 163 women were selected for the sample. Data were measured for each participant during the period between December 2008 and February 2009, and analyzed by chi-square test, t-test, Kruskal-Wallis test with post hoc, and logistic regression analysis. Samples were categorized into three groups by the compliance level of BSE for the last 6 months: Never-performers (i.e, women who had never performed BSE), irregularly-performers (i.e, women who performed BSE at least once), and regularly-performers (i.e, women who performed monthly BSE). Result: Significant differences were reported among never-performers, irregularly-performers and regularly-performers correlated to age, level of education, mammography, ultrasonography, clinical examination, benefit, and confidence. There was no significant difference between irregularly-performers and regularly performers. The significant factor influencing compliance with BSE was 'confidence', which explained 33.7% of the variance in compliance with BSE. Conclusion: Women who had more confidence in their ability to perform BSE were more likely to practice BSE. It is necessary to develop the strategy to enforce woman's confidence in complying with BSE.

  • Purpose: The purpose of this study was to investigate the level of uncertainty, physiological risk factors, self-efficacy, and self-management among stroke patients and to identify factors influencing their self-management. Methods: A descriptive correlational design was used for this study. A convenience sample of 149 patients with stroke were enrolled at C national university hospital from February to April in 2016. Data were collected using a structured questionnaire and electronic medical record. Collected data were analyzed using descriptive statistics, t-test, ANOVA, Pearson correlations, and multiple regression analysis with the SPSS/WIN 21.0 program. Results: There were significant negative correlations between uncertainty and self-efficacy (r=-.56, p<.001); between uncertainty and self-management (r=-.56, p<.001); and between total cholesterol and self-management (r=-.23, p=.005). There were significant positive correlations between self-efficacy and self-management (r=.78, p<.001); between uncertainty and total cholesterol (r=.24, p=.003). The significant factors influencing self-management were uncertainty and self-efficacy. Theses variables explained 62.7% of the variance in self-management. Conclusion: The results suggest that intervention programs to reduce the level of uncertainty and to increase the level of self-efficacy among patients would improve the self-management of stroke patients.

  • Purpose: The purpose of this study was to identify the influence of nursing practice environment, compassion fatigue and compassion satisfaction on burnout among clinical nurses in Korea. Methods: A descriptive crosssectional study was conducted. The sample consisted of 210 clinical nurses from three tertiary hospitals located in Seoul. Measurement instruments included the Korean version of the Practice Environment Scale of Nursing Work Index (K-PES-NWI) and Stamm's professional quality of life (ProQOL). Descriptive statistics, t-test, ANOVA, correlation analysis, and multiple regression were used to analyze the data. Results: Nursing practice environment had moderate negative influence on burnout (r=-.38, p<.001). Compassion fatigue had strong positive influence on burnout (r=.50, p<.001), while compassion satisfaction had strong negative influence on burnout (r=-.61, p<.001). The regression model explained 63% of variance of burnout and the compassion satisfaction was the most influencing factor for nurses' burnout. Conclusion: This study identified nursing practice environment, compassion fatigue and compassion satisfaction as influencing factors for nurses' burnout. Strategies to decrease compassion fatigue, enhance compassion satisfaction and create better nursing practice environment are recommended to decrease nurses' burnout.

  • The purpose of this study was to investigate the social distance of college students toward women immigrants by marriage and influencing factors. The considered factors were stereotypes, emotions and socioeconomic variables. The subjects were 324 college students and the data were collected during October 15-29, 2007. Findings of this study are as follows: the college students' scores of social distance toward women immigrants by marriage were less than midpoint (3.0), which means that the social distance of college students toward women immigrants by marriage was not that high. The college students' score of negative stereotype and positive stereotype were very similar. The score of sympathetic emotion was a little higher than negative emotion and positive emotion. To find the factors affecting social distances, regression analysis was executed. The social distances of students were influenced by negative emotions and positive emotions toward the women immigrants by marriage. Stereotypes toward women immigrants by marriage did not have a significant influence on social distances. These variables accounted for 44% of the variance of social distances.

  • Purpose: Patients with chronic hepatitis B need lifelong health care because of progressive liver damage. The purpose of this study was to identify factors associated with self-management compliance among patients with chronic hepatitis B. Methods: The research was a cross-sectional, descriptive design using questionnaires. The participants were 118 patients with chronic hepatitis B from outpatient department in a tertiary hospital. Their ages ranged from 20 to 64. Data were analyzed using descriptive statistics, t-test, ANOVA and multiple regression with PASW statistics 19.0 program. Results: There were statistically significant differences in self management compliance by gender, age, job, alcohol consumption, and smoking. A positive correlation existed between self-management compliance, awareness of the importance of management, and self efficacy. Stepwise multiple regression analysis for self-management compliance revealed that the most powerful predictor was self efficacy. Self efficacy, age, and alcohol consumption explained 37.5% of the variance. Conclusion: The results indicate a need to promote self-management compliance with these participants. The findings also suggest that consideration be given to characteristics of age and alcohol consumption in developing strategies for enhancing self efficacy and developing programs to promote self-management for patients with chronic hepatitis B.

  • This study examines the factors related to university students' positive beliefs about the consequences of maternal employment. A total of 338 university students in Seoul, Gyeong-gi, and Kyungnam area provided information about their socio-economic background, parents' employment history, achievement motivation, and gender egalitarian attitude. A two-way analysis of variance showed significant interaction effects of gender and grade on positive beliefs about the consequences of maternal employment. Multiple regression analyses by gender indicated that factors related with university students' positive beliefs about the consequences of maternal employment may differ by gender. For male students, grade, and socio-cultural gender egalitarian attitude were significantly related to positive beliefs about the consequences of maternal employment. For female students, grade, family monthly income, mother's employment during elementary school, and achievement motivation were related with positive beliefs about the consequences of maternal employment.

  • Purpose: Many studies have reported increased muscle activities in treatments using kinesio tape. However, most studies have focused on only muscles, so the effects of kinesio tape on structures other than the muscles are unknown. The purpose of this study is to explore the effect of kinesio tape for the fascia on trunk muscle activity during plank. Methods: Eighteen healthy participants took part in this study. The participants were asked to perform the plank in two conditions: on stable surface and unstable surface. Two kinesio tapes were attached along the spiral line introduced in the anatomy train. EMG was measured in each condition. EMG data were collected before and after attaching kinesio tape in each condition. Repeated analysis of variance (repeated ANOVA) was conducted to compare EMG activities levels between conditions. Results: EMG activities levels of trunk muscles, especially rectus abdominis and erector spinae activities were significantly increased during the plank with KT on both stable and unstable surfaces. Conclusion: KT applying on the fascia of targeted muscle increases the muscle activity. Therefore, we can also focus on the fascia to increase muscle activities not only on muscles.
