In a meta-analysis combining the results from different clinical trials, it is important to consider the possible heterogeneity in outcomes between trials. Such variations can be regarded as random effects. Thus, random-effect models such as HGLMs (hierarchical generalized linear models) are very useful. In this paper, we propose a HGLM framework for analyzing the binominal response data which may have variations in the odds-ratios between clinical trials. We also present the prediction intervals for random effects which are in practice useful to investigate the heterogeneity of the trial effects. The proposed method is illustrated with a real-data set on 22 trials about respiratory tract infections. We further demonstrate that an appropriate HGLM can be confirmed via model-selection criteria.

Methods: Data were collected by questionnaires from 265 nursing students in D city. Measures were ego resilience, problem solving process and clinical competency. Data was analyzed using frequency analysis, t-test, one-way ANOVA, person's correlation coefficients, and multiple regression analysis with SPSS/WIN 19.0 version. Result: The Ego resilience score of subjects was 2.80 out of a perfect score of 4, the problem solving process score of subjects was 3.12, and the clinical competency score of subjects was 3.49 out of a perfect score of 5. There was a significant positive correlation among ego resilience, problem solving process and clinical competency. The significant predictors of problem solving process and clinical competency were ego resilience. Conclusion: These findings indicate that there is a need to increase ego resilience to improve the problem solving process and clinical competency of nursing students. The results should be reflected in the development of effective curricula.

Purpose: In this study, behavioral styles of Dominance, Influence, Steadiness, and Conscientiousness (DISC) were examined and differences in job satisfaction and clinical competence among newly hired nurses were explored. Methods: For this explanatory correlational research, 176 newly hired clinical nurses were recruited from three university hospitals and one general hospital located in Seoul and Gyeonggi province. Data were collected in August, 2013 though self-report questionnaires. Results: The distribution of behavioral styles was 11.4%, 42%, 29% and 17.6% for Dominance, Influence, Steadiness, and Conscientiousness respectively. DISC behavioral styles were associated with sub-areas of job satisfaction such as professional position and doctor-nurse relationship. DISC behavioral styles were significantly associated with the total score for clinical competence and sub-areas of data collection, basic nursing skills, critical thinking, education and leadership, and attitudes toward professional development and practical skills. Multiple linear regression analysis showed that DISC behavioral styles predicted clinical competence (Adj. $R^2$=.14, F=9.42, p<.001). Conclusion: A focus on cultivating influential and steady behavioral styles among newly hired nurses can be helpful in improving job satisfaction and clinical competence. There is a need to improve interpersonal relationships through a deeper understanding of each person's behavioral style based on the analysis of DISC behavioral styles.

Purpose: The purpose of this study was to identify the relationship of clinical competency and self-directed learning in nursing students. Method: This study was conducted at two nursing colleges with students in a 2 year undergraduate nursing program. Data were collected from 182 students by means of self reporting questionnaires from October 1 to October 8, 2004. The data were analyzed by SPSS 10.0 PC programs using descriptive statistics, one-way ANOVA, Pearson correlation coefficient. Result: The questionnaire of students' clinical competency consisted of nineteen items based on a five point summated rating scale and was categorized into six subscales by factor analysis. The six subscales are nursing process, major nursing intervention, education for clients, observation and physical examination, and fundamental nursing. The more adaptable to major, the higher clinical competency (F= 3.406, p= .035) and self-directed learning (F= 7.444, p= .001). There was a positive correlation between students' clinical competency and self-directed learning (r= .367, p= .001). Conclusion: we concluded that future research should explore strategies for the development of self-directed learning to improve clinical competency of nursing students.
