  • Background: ${\beta}$-catenin plays a crucial role in the progression of breast cancer (BC) and a prognostic role of in BC patients has been widely reported. However, controversy still remains. Materials and Methods: Identical search strategies were used to search relevant literature in electronic databases updated to July 1, 2014. Individual hazard ratios (HRs) and 95% confidence intervals (CIs) were extracted and pooled HRs with 95%CIs were used to evaluate the strength of association between positive ${\beta}$-catenin expression in different subcellular locations and survival results of BC patients. Subgroup and meta-regression analyses were performed to explore heterogeneity. Funnel plots of Begg's and Egger's linear regression test were used to investigate publication bias. Heterogeneity and sensitivity were also assessed. All the work was completed using STATA. Results: A total of 2,204 patients from 12 evaluative studies were finally included. Pooled HRs and 95%CIs suggested that ${\beta}$-catenin expression in cytoplasm/nucleus had an unfavorable impact on both overall survival (OS) (HR: 1.93, 95%CI: 1.40-2.65) and disease free survival (DFS)/ recurrent free survival (RFS) (HR: 1.60, 95%CI: 1.20-2.13) in BC patients. However, here was no significant association between ${\beta}$-catenin expression in the membranes with OS (HR: 0.65, 95%CI: 0.42-1.02) or DFS/RFS (HR: 0.66, 95%CI: 0.38-1.13). Publication bias was absent in all of the four outcomes. Sensitivity analysis revealed that the results of this meta-analysis were robust. Conclusions: Positive ${\beta}$-catenin expression in cytoplasm/nucleus rather than in membrane is a significant prognostic factor in patients with BC who have been surgically treated.

  • Purpose: We measured the Oswestry Low Back Pain Disability Index (OLBPDI) and related factors in patients with low back pain. Methods: The sample consisted of 50 patients who received physical therapy at the physical therapy units of the Andong Seoul Sintong Clinic, St. Luke Clinic, and Yeongju Seoul Sintong Clinic in Andong and Yeongju city from October, 2007, to February, 2008. The OLBPDI questionnaire was administered by 5 physical therapists as a cross-sectional study. Student's t-test and analysis of variance (ANOVA/Tukey and Scheffe) were used to analyze OLBPDI score differences. We also used nonparametric statistic analysis (Wilcoxon rank sum test, Median test). Pearson correlation analysis (Spearman correlation analysis) was used to analyze the relationship between OLBPDI and the visual analogue scale (VAS). Multiple regression analysis was performed to determine the effects of independent variables on pain scores as defined by the OLBPDI. Results: The average patient age was 37.1 years (range: 18$\sim$78 years old), and time from onset was 21.7 months (1$\sim$180). OLBPD and VAS scores were 12.70 (3.0$\sim$28.0) and 5.14 (1$\sim$8), respectively. OLBPDI scores were 14.4 in patients taking medicine and 11.57 in those who did not. There was a statistically significant relationship between OLBPDI and VAS (r=0.54, p=0.0001; r=0.55, p=0.0001 by Spearman coefficient). Gender ($\beta$=6.14, p=0.0124), age ($\beta$=-2.01, p=0.0324), weight ($\beta$=0.31, p=0.0222), time from onset ($\beta$=1.54, p=0.0044), and VAS score ($\beta$=1.59, p=0.0004) were significantly associated with OLBPD by multiple regression analysis. Conclusion: Variables associated with OLBPD were gender, age, weight, time from onset, and VAS score. Collecting information on the pain index using OLBPDI was acceptable to patients with low back pain. Further research should explore the pain index by using larger sample sizes and longer follow-up periods.

  • Purpose: This study was performed to provide basic data for nursing intervention plan to improve health related to task by examining whether nurses' burnout is related with job stress, job satisfaction, social support, and self efficacy in hospitals. Methods: The participants were 320 nurses who work at 5 different university hospitals with individual agreement for this study. The questionnaire were provided to the subjects. Data analysis was done by Pearson correlation coefficient and multiple regression were used. Results: Estimated regression model of burnout of nurses was statistically significant (F=119.88, p<.001). Major factors which affect burnout of nurses were job stress (${\beta}=.54$), job satisfaction (${\beta}=-.31$), and social support (${\beta}=-.20$) which explained 53.4% of burnout of nurse. As a result of examining the assumption of the regression, all results were satisfactory with the assumption of the regression equation. Conclusion: Based on the results of the study, It is nacessary to reduce job stress and increse job satisfaction and social support in order to reduce burnout of nurse. Job stress management may be needed mostly because job stress was the highest level of prediction against burnout.

  • Purpose: This study was conducted to investigate the factors that affect subjective well-being in nursing students. Methods: A total of 236 nursing students participated in the study. Data was collected from November through December 2013 using a self-reporting questionnaire that surveyed the level of gratitude, interpersonal relationship ability, subjective happiness, and life satisfaction. Data was analyzed by descriptive analysis, t-test, ANOVA, Pearson correlation coefficients and multiple regression with the SPSS/WIN 18.0 program. Results: Subjective happiness positively correlated with gratitude (r=.41, p<.001) and interpersonal relationship ability (r=.55, p<.001). Life satisfaction positively correlated with gratitude (r=.53, p<.001) and interpersonal relationship ability (r=.37, p<.001). Significant predictors of subjective happiness included gratitude (${\beta}=.38$, p<.001), interpersonal relationship ability (${\beta}=.28$, p<.001) and major satisfaction (${\beta}=.17$, p=.002). The regression model explained 39.3% of subjective happiness. Significant predictors of life satisfaction included gratitude (${\beta}=.42$, p<.001), academic achievement (${\beta}=.15$, p=.006), interpersonal relationship ability (${\beta}=.16$, p=.008) and major satisfaction (${\beta}=.12$, p=.035). The regression model explained 35.3% of life satisfaction. Conclusion: To improve subjective well-being among nursing students, nurse educators should develop educational intervention programs to promote gratitude and interpersonal relationships.

  • In this paper, we discuss and review various measures which have been presented for studying outliers, high-leverage points, and influential observations when ridge regression estimation is adopted. We derive the influence function for ${\underline{\hat{\beta}}}\small{R}$, the ridge regression estimator, and discuss its various finite sample approximations when ridge regression is postulated. We also study several diagnostic measures such as Welsh-Kuh's distance, Cook's distance etc.

  • Purpose: To identify the effects on tuberculosis mortality of a tuberculosis control program conducted at 108 community health centers in terms of structure and process. Methods: The dependent variable was tuberculosis mortality, and the independent variables were the structure(type of centers, staff, nurses, doctors, budget) and process(chest X-ray checking, immunization, case detection, health education, patients registering & managing) of the tuberculosis control programs at the community health centers. Data were analyzed using descriptive analysis and stepwise regression analysis. Result: Tuberculosis morality was positively correlated with type of centers(rural area)(p<0.01), but negatively correlated with type of centers(large cities) (p<0.01), (middle cities)(p<0.05), staff FTE(p<0.05), and number of nurses(p<0.05). Regression analysis indicated that type of centers(rural area)($\beta$=0.457) and case detection($\beta$=0.234) had a significant effect on tuberculosis mortality. Conclusion: Ultimately, this study will provide information to improve the effectiveness of tuberculosis control programs in community health centers.
