This study investigated the effects of overtime work on the health-related quality of life (HRQoL) of Korean blue-collar workers. This cross-sectional study collected data on 229 Korean blue-collar workers in six small-sized companies from October to November 2015. The data were analyzed using hierarchical multiple regression analysis to estimate the effect of overtime work while considering convergence variables. In the hierarchical regression model, when overtime work variable was included in the model, $R^2$ change was statistically significant. The significant predictors for HRQoL were overtime work (${\beta}=.152$, p=.025), depression (${\beta}=-.192$, p=.003) and night shift work (${\beta}=-.201$, p=.032). The results of this study provide a basic data for establishing optimal working hours standards for improving the quality of life of Korean blue-collar workers.

The purpose of this descriptive research is to get basic data for educational program after investigating convergent effect of psychological capital on learning satisfaction of nursing freshmen. Using SPSS 21, T-test, ANOVA, Pearson's correlation coefficient and hierarchical multiple regression of the 164 collected data were carried out. The mean scores of psychological capital and learning satisfaction were above the middle, and the 'hope' was the highest among subdomains of psychological capital. There was a positive correlation between psychological capital and learning satisfaction(r=.665, p<.001). School performance(${\beta}=.311$), school life satisfaction(${\beta}=.191$) and psychological capital(${\beta}=.522$) were the significant factors of learning satisfaction in hierarchical multiple regression(F=37.651, p=.004). The explanatory rate of variables on learning satisfaction was 57.4%. It is needed applying these results in developing learning satisfaction programs, but it isn't appropriate to generalize these results conducted on nursing freshmen in one university.

The purpose of this descriptive research conducted among 125 pediatric nurses was to get basic data for nursing educational program on peripheral intravenous catheterization. The collected data using Protocol of Pediatric Peripheral Intravenous Infusion of Choi et. al.(2016) and Core Basic Nursing skills & Protocol ; Intravenous Infusion of Korean Accreditation Board of Nursing Education(2017) were analyzed using SPSS 21.0. Nursing performance of pediatric nurses was the lowest in education, and the highest in side effect management. There were significant differences in subarea of nursing performance according to general characteristics. There was a positive correlation between education and nursing performance(r=.486, p<.001), and factors influencing nursing performance were education(${\beta}=.472$), working department(${\beta}=.216$) and marital status(${\beta}=.169$)(adj $R^2=0.314$, p<.001). These results can be used as basic data on nursing educational program on peripheral intravenous catheterization for pediatric nurses after repeated study by expanding the number of subjects.

The Wnt/${\beta}$-catenin pathway plays important roles in a variety of biological processes, such as cell proliferation, differentiation, and organ development. Here, we used a cell-based reporter assay to identify bryostatin-1, a natural macrocyclic lactone, as an inhibitor of the Wnt/${\beta}$-catenin pathway. Bryostatin-1 suppressed ${\beta}$-catenin response transcription (CRT), which was activated by a Wnt3a-conditioned medium (Wnt3a-CM), through a decrease in the intracellular ${\beta}$-catenin protein levels, without affecting its mRNA level. In addition, pharmacological inhibition of proteasome abrogated bryostatin-1-mediated down-regulation of the ${\beta}$-catenin protein level. Our findings suggest that bryostatin-1 attenuates the Wnt/${\beta}$-catenin pathway through the promotion of proteasomal degradation of ${\beta}$-catenin.
