Purpose: This study was conducted to examine the effects of line dance and walking on cardiovascular disease risk factors in obese elderly women. Methods: Subjects consisted of 102 elderly women (i.e., 51 women in the experimental group and 51 women in the comparison group) who had a body mass index over 25 kg/m2. Participants in the experimental group performed line dance (i.e., sixty minutes session, three times a week for 8 weeks), and participants in the comparison group performed walking (i.e., forty to sixty minutes session, three times a week for 8 weeks). Outcome variables were body mass index, body fat percentage, blood pressure, blood lipids, and stress. Data were analyzed using descriptive statistics, t-test, paired t-test, and ANCOVA with the SPSS 22.0 program. Results: The participants in the experimental group showed significantly increased high-density lipoprotein cholesterol (t=-3.12, p=.002) and decreased scores of stress (t=2.59, p=.011) compared to the comparison group. Conclusion: Line dance improved high-density lipoprotein cholesterol and reduced the stress level of obese older women in the community.

Purpose: The purpose of this study was to examine the effects of the leader-member exchange and organizational commitment on their nursing work performance of clinical nurses. Methods: This study participants included 213 nurses working at a tertiary hospital in B city in south Korea. Data were collected by self-reported questionnaires and included leader-member exchange, organizational commitment and nursing work performance. The data were analyzed using descriptive statistics, independent t-test, one way ANOVA, Pearson’s correlation coefficients and multiple regression analyses with IBM SPSS 18.0 program. Results: The significant predictors of nursing work performance were organizational commitment (β=.25, p<.001), clinical career (β=.21, p=.002), relationship with colleagues (β=.20, p=.001), contribution as a sub-area of leader-member exchange (β=.17, p=.005), clinical career in current department (β=.13, p=.049), and religion (β=.12 p=.031). These variables explained 33.2% of the variance in nursing performance. Conclusion: It is suggested to highlight the impotance of nursing work performance and to develop and execute the nursing intervention program for enhancing leader-member exchange relationships and organizational commitment on the basis of appropriate career management for nurses and the enhancement of relationships with colleagues.

Purpose: This study aimed to investigate the influence of stress, anxiety, and depression on the quality of sleep in patients with chest pain. Methods: A descriptive correlation design was used. Eighty-eight patients with chest pain who were admitted to the cardiology department at the P National University Hospital to undergo coronary angiography were recruited as participants. The data were collected using the Visual Analog Scale (VAS), the Canadian Cardiovascular Society Classification (CCSC), the Perceived Stress Scale (PSS), the State-Trait Anxiety Inventory (STAI), the Beck Depression Inventory (BDI), and the Pittsburgh Sleep Quality Index (PSQI). The date were analyzed using t-test, ANOVA, Pearson's correlation coefficient, and hierarchical multiple regression using the SPSS 23.0 program. Results: There were significant correlations between quality of sleep and total cholesterol (r=.24, p=.029), and low-density cholesterol (r=.26, p=.020). There were significant positive correlations between quality of sleep and stress (r=.40, p<.001), anxiety (r=.29, p=.007), and depression (r=.38, p<.001). The factor affecting the quality of sleep was stress (β=.38, p=.011), which explained 22.6% of the variance. The quality of sleep was significantly worse when reported stress levels was higher. Conclusion: When developing a sleep management program for patients with chest pain, it is necessary to consider the stress levels of the patient.
