Purpose: The purpose of this study was to investigate the mediating effect of resilience on the relationship between emotional labor and happiness of clinical nurses. Methods: A descriptive, cross-sectional study was conducted with 224 clinical nurses who had one or more years of clinical experiences from four general hospitals in D city in Korea. Data collected from the survey using self-reported questionnaires were analyzed by t-test, one-way ANOVA, Pearson's correlation coefficients, and multiple regression analysis using IBM SPSS statistics 21.0 program. Results: There were statistically significant correlations among variables; a negative correlation between happiness and emotional labor, a positive correlation between happiness and resilience, and a negative correlation between emotional labor and resilience. Meanwhile, resilience had a partial mediating effect on the relationship between emotional labor and happiness. That is, resilience can play an important role between emotional labor and happiness of clinical nurses as a mediator. Conclusion: Considering the findings of this study, developing programs that can improve resilience of clinical nurses who experience emotional labor are needed to increase their level of happiness.

Purpose: The purpose of this study was to investigate the relationship between depression and attention concentration by smoking status among adolescents. Methods: Depression was measured by Radloff's Center for Epidemiological studies Depression(1977) and modified by Korean(Chon & Lee, 1992), attention concentration measured by Nideffer's Test of Attention and Interpersonal Style(1976) and modified by Korean adolescents(Seo, 2004; Shin, 1988). The collected data was analyzed by the $Mean{\pm}SD$, ${\chi}^2$-test, ANOVA, Scheffe and Pearson correlation coefficient(SPSS 13.0). Results: 1. The smoking level appeared to heavy smoking group 31(22%), light smoking group 15(11%), non smoking group 92(67%). 2. The smoking level was different between the time to begin smoking, period of smoking and smoking amount/day. 3. Smoking group's depression was higher than those of the non smoking group and attention concentration was lower than those of the non smoking group. 4. The smoking amount had a significant positive correlation with depression and a significant negative correlation with attention concentration. Depression had a significant negative correlation with attention concentration. Conclusion: The result of this study offered the basis data for smoking prevention and treatment of adolescents.

microRNA는 유전자의 전사 후 과정에서 negative regulation을 담당하는 small noncoding RNA의 한 증류이다. 최근까지 330여개의 인간 microRNA가 발견되었지만 그들의 기능이 밝혀진 것은 소수에 불과하다. microRNA의 기능은 3'UTR에 불완전 상보결합을 통해 negative regulation을 받게 되는 유전자의 기능으로부터 유추되는 것이 일반적이다. 특별히 유전체상에 군집화 된 microRNA들은 하나의 전사체로부터 발현되는 것으로 판단되며, 같은 또는 관련된 기능을 하거나 같은 목표 유전자를 조절하기 위한 functional family일 가능성이 높다. 또한 이러한 functional family는 하나의 전사체로부터 발현되기 때문에, 조직별로 조건별로 같은 발현 패턴을 보여야 한다. 본 연구에서는 발현데이터로부터 microRNA functional family를 탐색하기 위해, 5개의 연구 그룹에서 공개한 조직별 microRNA 발현데이터를 표준화 작업을 거친 후 통합하고 k-nearest neighbor 알고리즘을 이용해 결측치를 보정한 후 microRNA 발현사이의 correlation을 계산한다. 이때 데이터 통합에서 생기는 문제에 robust한 결과를 얻기 위해 실제 발현데이터가 아닌 rank 데이터부터 correlation을 측정한다. 계산된 spearman ranked correlation 결과와 microRNA의 genomic coordination 정보로부터 34개의 functional family를 정의할 수 있었다.

The purpose of the study is to examine the influences of irrational belief and social support on adolescents' social anxiety. Questionnaires regarding irrational belief, social support, and social anxiety were administered to 566 2nd and 3rd grade middle-school students in Gyeonggi Province. Finally 523 questionnaires were collected and statistically analyzed through t-test, Pearson's correlation analysis, hierarchical and stepwise multiple regression analysis. The results of the study were as follows: 1) While there were gender differences in social anxiety, irrational belief, and social support sources, no differences in social support types were observed. 2) While social anxiety and irrational belief showed a positive correlation, social anxiety and social support revealed a negative correlation. Additionally, irrational belief and social support showed a negative correlation. 3) Irrational belief(catastrophizing, extreme anxiety and fear, personal perfection, and helplessness), emotional social support, and social support from friends were significant predictors of social anxiety. 4) Irrational belief which predicted each social anxiety subtype was varied.

This study was carried out to investigate fast food consumption patterns, nutrition knowledge, dietary attitude of middle and high school students in Busan. A questionnaire survey was conducted among 562 students from April 8 to April 22 in 2006. The results are summarized as follows. Convenience to eat is the best motive for visiting fast food restaurants. Nutrition knowledge scores of middle school male students were lower than those of the other groups. The more nutrition knowledge female students have, the lower fast food consumption became. There was no significant difference in nutrition knowledge and fast food consumption in male students. There was a significantly positive correlation between education levels of their parents and dietary attitude of the subjects(p<0.01). Pocket money showed a significantly negative correlation with dietary attitude and with fast food use frequency(p<0.05). There was a significantly positive correlation between nutrition knowledge and dietary attitude of the subjects. The use frequency of fast food showed a negative correlation with dietary attitude(p<0.01) and nutrition knowledge(p<0.05) of the subjects. Therefore, proper nutrition education is required to improve their nutritional status and dietary attitude.

Purpose: This study was conducted to explore the mediating effect of nutritional status on the relationship between symptom experience and functional status of patients with Chronic Obstructive Pulmonary Disease (COPD). Methods: A total of 141 COPD patients visiting D hospital and I hospital in B city were enrolled in this study. Data were collected from January 2017 to July 2017. Outcome variables were measured by Mini Nutritional Assessment Short-Form (MNA-SF) for nutritional status, The Memorial Symptom Assessment Scale (MSAS) for symptom experience, and The Functional Performance Inventory Short Form (FPI-SF) for functional status. The data were analyzed with descriptive statistics, Pearson's correlation, and path analysis using SPSS/WIN 21.0 and AMOS 25. Results: There was a significant negative correlation between symptom experience and nutritional status (r=-.61, p<.001), a significant negative correlation between symptom experience and functional status (r=-.40, p<.001), and significant positive correlation between nutritional status and functional status (r=.47, p<.001). Symptom experience had indirect effects on functional status through nutritional status. Conclusion: For enhancing functional status in COPD patients, it is necessary to develop nursing intervention programs to enhance symptom management as well as nutritional status.

This study was conducted to identify the characteristics of activities of daily living(ADU) and its influencing factors in patients with chronic arthritis. The data were obtained from 104 patients with chronic arthritis in one university hospital from May to August. 2000. For analysing data. SAS program was used for t-test. ANOVA, Schefte test. Pearson correlation. and stepwise multiple regression. The results were as follows: 1. The variables which influenced self-efficacy were duration of disease. number of painful joint, quality of sleep and alcohol drinking. 2. The variables which influenced fatigue were diagnosis and number of painful joint. 3. The variables which influenced ADL were age. duration of disease. diagnosis. number of painful joint. number of exercise and alcohol drinking. 4. ADL was positive correlation with self-efficacy and negative correlation with fatigue. And self-efficacy was negative correlation with fatigue. 5. The predictors to explain ADL were self-efficacy. number of painful joint. lupus. duration of disease and religion. These predictors explained $66.01\%$ of the activites of daily living. According to these findings. the most significant influencing factor of ADL was self-efficacy. therefore the development of nursing intervention for enhancing self-efficacy would be needed. Also. it is suggested that an exercise program should be recommended as one of useful and appropriate nursing intervention for reducing fatigue and increasing ADL.

Purpose: The purpose of this study was to identify factors influencing job satisfaction in hospice nurses. The focus was on emotional labor and burnout. Methods: Between September 30 and October 18, 2013, hospice nurses (n=63) in 5 hospitals in 4 cities completed measures of emotional labor, burnout, and job satisfaction. Data were collected using questionnaires and analyzed using descriptive statistics, t-test, ANOVA, Pearson correlation coefficient, and multiple regression with the SPSS/Win 21.0 program. Results: The mean score per item for emotional labor was 3.0, the mean of burnout score was 2.7, and the mean job satisfaction score was 3.4. Emotional labor showed a positive correlation with burnout (r=.61), and a negative correlation with job satisfaction (r=-.52). Burnout showed a negative correlation with job satisfaction (r=-.64). The factors influencing job satisfaction were burnout (${\beta}$=-.65, p<.001) and clinical experience (${\beta}$=.25, p=.007). Burnout and clinical experience explained 57.0% of the variance in hospice nurses' job satisfaction. Conclusion: The findings of this study indicate a need to develop strategies to prevent burnout and control emotional labor in order to increase job satisfaction for hospice nurses.

Purpose: The purpose of this study was to identify factors affecting professional burnout in intensive care unit (ICU) nurses. Method: Data were obtained through questionnaires from 240 ICU nurses working in hospitals of 500 beds or more in two cities in South Korea. Data analysis was done with t-test, ANOVA, Scheffe test, Pearson correlation coefficients and multiple stepwise regression with SPSS WIN 14.0. Result: Work stress was positively correlated with level of professional burnout and there was a negative correlation between hardiness and professional burnout. Social support was negatively correlated with level of professional burnout. Hardiness had a positive correlation with social support and a negative correlation with work stress. The explained variances for burnout was 44.7% and factors affecting professional burnout in the ICU nurses' were work satisfaction, work stress, social support, and hardiness. Conclusion: The findings indicate that high levels of stress coupled with low levels of hardiness and social support in ICU nurses result in high levels of professional burnout. Reducing work stress and the level of professional burnout in ICU nurses and increasing work satisfaction can be done by enhancing the mediating factors of hardiness and social support through educational efforts and nursing and administrative support.
