Purpose: The purpose of this study was to identify the influence of nurses' emotional intelligence and communication within the organization on teamwork in Armed Forces hospitals. Methods: This study employed a cross-sectional design with a convenience sample of 195 nurses from five Armed Forces hospitals in Korea. Data were collected through a self-administered questionnaire from August 7 to 23, 2017 and analyzed using descriptive statistics, t-test, ANOVA, Pearson's correlation coefficient, and multiple regression. The SPSS/WIN 21.0 program was used for all analyses. Results: The degree of teamwork was $5.03{\pm}0.73$, with scores ranging from 1 to 7. Emotional intelligence and communication within the organization were positively correlated with teamwork. Specifically, communication within the organization (${\beta}=.60$, p<.001), the intensive care unit (${\beta}=.21$, p=.001), and the medical general ward (${\beta}=.17$, p=.010) were identified as factors influencing teamwork. This model explained 51% of the variance in teamwork, and it was statistically significant (F=35.09, p<.001). Conclusion: These results imply the need to develop an approach including communication within the organization to improve teamwork among nurses in Armed Forces hospitals.

Purpose: This study investigates the status of medication use of the elderly with chronic disease taking non-opioid analgesics and attempts to identify factors influencing medication adherence. Methods: Data were collected from September 1 to October 19, 2016. A structured questionnaire was used for face-to-face interview with a convenience sample of 161, elderly people with chronic disease taking non-opioid analgesics. The survey included questions about status of medication use, medication adherence, symptom experience, depression and family function. Data were analyzed using descriptive statistics, t-tests, ANOVA, Pearson's correlation coefficients, and stepwise multiple regression with IBM SPSS 23.0 program. Results: The mean score of medication adherence of the elderly with chronic disease was $4.48{\pm}2.35$. Experiences of side effects (${\beta}=.31$, p< .001), use of over-the-counter pain medication (${\beta}=.19$, p= .009), and family function (${\beta}=.16$, p= .031) were identified as significant predictors. The final model explained 18.0% of the variation of medication adherence of the elderly with chronic disease taking non-opioid analgesics (F= 12.30, p< .001). Conclusion: Therefore, as a strategy to improve medication adherence of the elderly with chronic disease, therapeutic intervention should be developed to improve family function and to manage with personalized plans considering experiences of side effects and use of over-the-counter pain medication.

Purpose: We evaluated the relationship of prostate-specific antigen (PSA) and obesity indices (weight, body mass index [BMI] and waist circumference [WC]) in Korean middle-aged men. Materials and Methods: From February to September 2013, 1,900 police men under 60 years old who participated in a prostate health screening program were included this cross-sectional study. All subjects underwent clinical examinations including weight, height, BMI, WC, fasting blood sugar, lipid profiles, estimated glomerular filtration rate (GFR), and PSA. Total prostate volume (TPV) was assessed clinically. Spearman correlation and multiple linear regression tests were performed to evaluate the obesity indices and PSA relationships. Results: The mean age was $52.0{\pm}4.7years$, and the mean PSA was $0.97{\pm}0.99ng/mL$. The PSA showed a significant positive correlation with the age (r=0.108, p<0.01), TPV (r=0.349, p<0.01), height (r=-0.052, p<0.05), weight (r=0.186, p<0.05), low-density lipoprotein cholesterol (r=0.056, p<0.05), and GFR (r=-0.096, p<0.01). All obesity indices including weight, BMI, and WC showed negative correlations with PSA (beta=-0.013, p<0.001; beta=-0.039, p<0.001; and beta=-0.010, p=0.005; respectively) in age and TPV-adjusted model. Conclusions: Common obesity indices (weight, BMI, and WC) were associated with lower PSA in Korean middle-aged population. Thus, an individual's degree of obesity should be considered when PSA is checked in the first prostate cancer screening of life.

Purpose: This descriptive study aimed to explore the effects of bullying, health promotion lifestyles, and physical symptoms on the occupational stress of new nurses in general hospitals. Methods: The participants of this study were 157 new nurses in fivegeneral hospitals with 100 to 399 beds in Gyeonggi-do. Data were collected from January to February, 2018, using a structured questionnaire and analyzed using the SPSS software version 20. Results: A total of 60.5% of the participants experienced bullying, and 38.2% experienced bullying more than 10 times a month. The perceived severity of bullying was severe (32.4%) and the nurses' first bullying experience began within the first six months (47.7%). Their occupational stress was scored 3.1. The regression model for occupational stressors was significant (F=23.86, p<.001), and the total explanatory power was 46.8%. The variables affecting occupational stress were bullying awareness (${\beta}=-.30$, p<.001), preceptor satisfaction (${\beta}=-.30$, p<.001), and health promotion lifestyles (${\beta}=-.26$, p=.001). Conclusion: It is important to reduce the incidence of bullying in order to help new nurses with high occupational stress. Stress management programs are needed to improve relationships between new nurses and preceptors and to encourage their health promotion lifestyles.
