Purpose: This study was to identify the impact of spiritual wellbeing and social support on the depression among middle-aged women. Descriptive study design was used. Methods: The subjects completed the structured questionnaires: the 'Spiritual Well-being Scale', developed by Paloutzian & Ellison, 'the Social Support Scale' developed by Park, and 'the CES-D Scale' developed by Radloff. Data were collected from 216 middle aged women in B metropolitan city and J city. The data were analyzed using t-test, ANOVA, Scheff$\acute{e}$ test, Pearson's correlation coefficients, and multiple regressions. Results: Participants with higher depression had lower scores for spiritual wellbeing (r=-.57, p<.001) and lower scores for social support (r=-.49, p=.011). The influencing factors on depression were spiritual wellbeing, social support, and utilization of spare time. These variables were explained 46% of the variance in depression. Conclusion: The depression of the middle-aged women can be reduced when spiritual wellbeing and social support are improved. Therefore, we suggested to develop nursing intervention programs in order to improve spiritual wellbeing and social support of middle-aged women for reducing their depressions.

Purpose: This study was aimed to investigate the factors influencing problem drinking of male drinkers above 19 years old according to the life cycle. Methods: The study subjects consisted of a representative community sample of 2,229 male drinkers aged 19 and older from the 2011 Korean National Health and Nutrition Examination Survey. The collected data were analyzed using descriptive statistics, Rao-Scott $x^2$-test, simple and multiple logistic regressions. Results: The problem drinking rates were 38.7% in adolescence, 44.5% in middle age, and 23.9% in senescence. In adolescence, the predictors of problem drinking included occupation, stress recognition, and smoking. In middle age, the predictors of problem drinking were education level, depression, and smoking. In senescence, the predictors of problem drinking were not identified in this study. Conclusion: The findings of this study suggested that the factors influencing problem drinking of male drinkers were different according to life cycle. Thus different intervention methods should be developed for each age group in order to intervene the problem drinking.

Purpose: This study investigated the prevalence of hypertension, explored sleep duration, and examined the related factors to hypertension in Korean middle-aged adults. Methods: Using raw data from the Korean National Health and Nutritional Examination Survey (KNHANES) conducted from 2008 to 2010, a secondary analysis was performed with data from 13,230 adults aged 30~64 years. ${\chi}^2$-test and multiple logistic regressions was used for the data analysis. Results: The prevalence of hypertension among Korean middle-aged adults was 21.8% and 40.3% among participants reported that their average sleep duration was below six hours a night. Risk factors for hypertension include: female (the odds ratio (OR) 1.66 for male), 50~64 years age group (OR 3.66 for 30~49 years age group), education level of elementary school (OR 1.84 for university level), low household income (OR 1.27 for upper), obesity (OR 2.41), high risk drinking (OR 1.64), and sleep duration${\leq}6$ hrs (OR 1.16 for 8 hrs of sleep). Conclusion: High risk population of hypertension could be male, aged, low education, and low income. Obesity, high risk drinking, and short sleep duration should be considered as risk factors for hypertension. Interventions for obesity management, adequate alcohol drinking and sleep duration could be considered for preventing hypertension.

Purpose: The purpose of this study was to describe the impact of fatigue and distress on self-efficacy among breast cancer survivors and to provide a base for development of nursing intervention strategy to improve self-efficacy. Methods: A descriptive research design was used. The subjects were 158 patients who were either being treated or were receiving follow-up care at a university breast center in D City from May 30 to August 30, 2014. Structured questionnaires, Revised Piper Fatigue Scale, Distress Thermometer, and Self-Efficacy Scale for Self-Management of Breast Cancer were used to measure fatigue, distress, and self-efficacy. Data were analyzed using t-test, ANOVA, Pearson's correlation coefficients, and multiple regressions. Results: The mean scores of fatigue, distress, and self-efficacy were 3.83, 4.31, and 3.77, respectively. There were significant differences among participants in terms of educational background, current treatment methods, perceived health status, economic burden for fatigue and perceived health status for distress. Self-efficacy was impacted by age, educational background, marital status, average monthly income, perceived health status, and medical expenses. Fatigue, age, and the burden on medical expense had the most impact on self-efficacy, accounting for 17% of the variance. Conclusion: Fatigue should be managed to improve self-efficacy of breast cancer survivors. Therefore, nursing programs designed to decrease fatigue may be helpful.

Earthwork activities are typically performed by heavy duty diesel (HDD) construction equipment that consumes large quantities of diesel fuel use and emits large quantities of pollutants, including nitrogen oxides (NOx), particulate matters (PM), hydrocarbon (HC), carbon monoxide (CO), and carbon dioxide ($CO_2$). This paper presents the framework for a model that can be used to estimate the production rate, activity duration, total fuel use, and total pollutants emissions for earthwork activities. A case study and sensitivity analysis for an excavator performing excavations are presented. The tool is developed by combining the multiple linear regressions (MLR) approach for modeling the productivity with the EPA's NONROAD model. The excavator data from RSMeans Heavy Construction Data were selected to build the productivity model, and emission factors of all type of pollutants from NONROAD model were used to estimate the total fuel use and emissions. The MLR model for the productivity rate can explain 92% of the variability in the data. Based on the model, the fuel use and emissions of excavator increase as the trench depth increase, but as the bucket size increase, the fuel use and emissions decrease.

Objectives: The purpose of this study was to examine factors influencing the retention intention of dental hygienists in clinical practice. Findings will assist in the development of strategies to increase their retention. Methods: A self-reported questionnaire was completed by 261 dental hygienists who work at dental hospitals and clinics in the Jeollabuk-do area. Data were analyzed using descriptive statistics, independent t-test, one-way ANOVA (post-test Duncan), and multiple regressions. Results: The variable that demonstrated the largest influence on the retention intention of dental hygienists was purpose/meaning (${\beta}=0.283$), followed by transcendental calling (${\beta}=0.198$). These factors relate to the sense of calling. The third most influential variable was pay (${\beta}=0.150$). This relates to general characteristics. The fourth most influential factor was the frequency of emotion display (${\beta}=-0.112$), which relates to one of the sub-areas of emotional labor. Conclusions: In order to strengthen the retention intention of dental hygienists, diverse approaches should be implemented, with particular consideration for their sense of calling, emotional labor and pay.

Driver's feeling is variously affected by lots of components such as engine, frame, wheels, and seats during the operation of automobiles. The main objective of this research is to identify the correlation between subjective evaluation and vibration metrics that was set by ISO to investigate development of the car vibration quality index using multiple linear regressions (MLR). A previous research related with automotive vibration quality used the method of calculating acceleration values of the point of a seat, a seat back, foot as RMS for objective evaluation. The automotive comfort is determined by RMS values. In comparison with the previous research, this study includes not only the vibration metrics, but also subjective values by jury evaluation. By indentifying the correlation between subjective evaluation and vibration metrics, the automotive vibration quality index is developed through MLR. Based on the results of this study, the proposed the automotive vibration quality index which developed through MLR will be helpful to obtain objective and reliable automotive comfort values.

This study examined the effects of mothers' reactions toward children's negative emotion as well as mothers' emotional expressivity on children's social withdrawal. 206 children (103 boys, 103 girls; aged 4-5 years old) and their mothers participated in the study. Mothers reported their reactions to their child's negative emotion along with their expressivity. The teachers completed a rating scale to measure children's social withdrawal. The collected data was analyzed using descriptive statistics, Pearson's productive correlation coefficient, and hierarchical multiple regressions. The results showed a relation between mothers' distress reactions and punitive responses and children's social withdrawal. A mother's positive expressivity was negatively related to a child's social withdrawal. A hierarchical regression analysis indicated that the effects of mothers' punitive responses and minimization responses on children's withdrawal were moderated by a mother's positive expressivity. Mothers' punitive responses and minimization responses were positively associated with children's social withdrawal, especially for children who had the lowest level of mother's positive expressivity.

Purpose: This study aims to assess university freshmen's concern of and satisfaction with their health and body and to analyze this in relation to their health habits, thereby aiding university students in forming sound health habits. Method: The subjects of this study were 338 freshmen at A University, located in B City. The questionnaire had 34 questions and the collected data was analyzed with t-test, $x^2$-test, and multiple regressions. Result: The average points of the subjects' health habits were 6.01 for male and 5.65 for female, showing a median range. Concern about health (male 13.63 points, female 13.10 points) and satisfaction with their own body (male 8.26 points, female 7.71 points) showed no significant difference between males and females. Females had more concern about their body (p=.001), and males' satisfaction with health was higher than females', which was statistically significant (p=.0.41). As for factors that have an effect on health habits, male students had health concerns ($\beta$=.395), health satisfaction ($\beta$=.212), and body concerns ($\beta$=-.209), and female students had health concerns ($\beta$=.317) and health satisfaction ($\beta$=.139). Conclusion: University freshmen are likely to have diverse undesirable health habits and therefore need positive improvement in their health habits.

The purpose of this study was to explain the influence of depression on the life satisfaction of the elderly with hypertension. Also, we were focusing whether there is a mediating effect of subjective health status between depression and life satisfaction of the elderly with hypertension. 2,198 persons with hypertension over 65 years of age were selected from the data of KLoSA(Korean Longitudinal Study of Ageing), administered by The Korea Employment Information Service in 2014. Life satisfaction was measured by 10-Likert. The depression measured by CES-D10. The mediating variable is subjective health status measured by 5-Likert. As the method of analysis, the multiple regressions were used with SPSS 19.0. The result of the study shows that depression has a negative influence on life satisfaction and a negative influence on subjective health status. It was also verified that the subjective health status variable has a mediating effect between depression and life satisfaction. These results present the importance of psychological approach for the health promotion experts intervening with the elderly with hypertension.
