Whether This paper argues that teacher efficacy is an affective affiliate of pedagogical content knowledge (PCK) based on empirical data of a study on the nature and construct of PCK. This study was a collective case study utilizing qualitative research methods. The participants of the study were three high school science teachers in the U.S. Data was collected from multiple sources such as classroom observation, interviews, teachers' written reflection, students' work samples, and researchers' field notes. Data was analyzed using the "In-depth Analysis of Explicit PCK" developed by the author. Data analysis indicated that teacher efficacy played a critical role in developing PCK by facilitating the movement from PCK to the enactment of PCK.

Purpose: The purpose of this study was to provide basic data for the development of weight control programs to maintain and promote healthy behavior in women college students by identifying their weight control behaviors and factors that influence these behaviors. Method: Data were collected from 300 women student participants and were analyzed using descriptive statistics, t-test, ANOVA, Pearson correlation coefficients, and multiple regression with the SPSS 18.0 program. Result: Weight control behavior showed a significant difference according to participants' gender role identity type. Weight control behaviors were correlated with self-efficacy, body image, objective BMI, and ideal BMI. Factors influencing weight control behavior were self-efficacy (${\beta}$= .449, $p$<.001), secret method for weight loss (${\beta}$= .181, $p$<.001), monthly allowance below 200,000 won (${\beta}$= .156, $p$= .006), weight control support from others (${\beta}$= .124, $p$= .013), eating breakfast (${\beta}$= .119, $p$= .015), and age (${\beta}$= .113, $p$= .023) with R-sq. value of 45.3%. Conclusion: The results of the study indicate that development of interventions for weight control behavior and health education for college women should reflect identified factors influencing weight control behavior and gender role identity.

This study explored the conceptual framework of dieticians' intentions to recommend functional food and the mediating role of consumption frequency. A web-based survey was designed using a self-administered questionnaire. A sample of Korean dieticians (N=233) responded to the questionnaire that included response efficacy, risk perception, consumption frequency, and recommendation intention for functional foods. A structural equation model was constructed to analyze the data. We found that response efficacy was positively related to frequency of consumption of functional foods and to recommendation intention. Consumption frequency also positively influenced recommendation intention. Risk perception had no direct influence on recommendation intention; however, the relationship was mediated completely by consumption frequency. Dieticians' consumption frequency and response efficacy were the crucial factors in recommending functional foods. Dieticians may perceive risks arising from the use of functional foods in general, but the perceived risks do not affect ratings describing dieticians' intentions to recommend them. The results also indicated that when dieticians more frequently consume functional foods, the expression of an intention to recommend functional foods may be controlled by the salience of past behaviors rather than by attitudes.

Purpose: The purpose of this study was to identify factors influencing job satisfaction among nurses working in college health centers in order to enhance their role functions and to increase their work capabilities. Method: In this study a cross-sectional survey was used to collect data from 106 nurses working in college health centers. Collected data were analyzed using frequency, Pearson correlation coefficients, independent t-test, one-way ANOVA and multiple regression with the SPSS 20.0. Results: Mean scores for self-efficacy, job stress and job satisfaction for the participants were 3.86 (5-point scale), 2.51 (5-point scale) and 3.37 (5-point scale) respectively. There was a negative correlation between self-efficacy and job satisfaction (r=-.653, p<.001). Factors influencing job satisfaction were job stress (${\beta}$=-.58, p=<.001), level of perception among the nurses that they were contributing to the health promotion of students (${\beta}$=-.21, p=.005) and marital status (${\beta}$=.17, p=.029). These 3 elements accounted for 47.7% of the variance in job satisfaction. Conclusions: The results indicate that reduction in job stress and increase in the perception that nurses are contributing to the promotion of students' health are important to reinforce the role function of nurses and to increase their work capabilities.

The poor outcome of advanced ovarian cancer under conventional therapy necessitates new strategies to improve therapeutic efficacy. β-glucosidase (encoded by GBA) is a lysosomal enzyme and is involved in sphingolipids metabolism. Recent studies revealed that β-glucosidase plays a role in cancer development and chemoresistance. In this work, we systematically evaluated the expression and role of GBA in ovarian cancer. Our work demonstrates that inhibition of β-glucosidase has therapeutic potential for ovarian cancer. Gene Expression Profiling Interactive Analysis database, western blot and immunohistochemistry analyses of patient samples demonstrated that GBA mRNA and protein expression levels were significantly increased in ovarian cancer compared to normal tissues. Functional studies using gainof-function and loss-of-function approaches demonstrated that GBA overexpression did not affect growth and migration but alleviated cisplatin's efficacy in ovarian cancer cells. In addition, GBA depletion resulted in growth inhibition, apoptosis induction, and enhancement of cisplatin's efficacy. Of note, we found that GBA inhibition specifically decreased receptor tyrosine kinase AXL level, leading to the suppression of AXL-mediated signaling pathways. Our data suggest that GBA represents a promising target to inhibit AXL signaling and overcome cisplatin resistance in ovarian cancer.

The purpose of this study is to investigate the improvement of career self-efficacy of middle school students through the fashion career educational program designed for Free-semester. For the purpose of this study, three middle schools were implemented and their effects were verified. First, the fashion career educational program was designed based on subordinate elements of career education: job information searching, self-understanding and exploration, career-planning, and problem-solving. The results of this study were as follows: First, the fashion career education program has positive effects on the improvement of career self-efficacy of middle school students. The positive experiences of accomplishment through task solving, the role experience of successful role model, the return of successful experience, and the positive interactions of teachers and friends that can be done in the future have brought positive changes to career self-efficacy. Second, this program has positive effects on the career self-efficacy sub-factors, which are career exploration efficacy, career decision making efficacy, and career-performing efficacy. As a result of practicing and exploring activities related to fashion, It seems to be due to the self - confidence of planning and preparing their own career through their self-understanding and exploration, collecting information of job, problem solving, career planning, etc.

This study examines factors influencing family life-satisfaction, focusing specifically on the role of spousal social support, trust of children and self-efficacy. Based on previous studies, two hypotheses were generated. A total of 857 adults (111 fathers and 111 mothers parents of elementary school students and 108 mothers and 108 fathers of high school students) completed a questionnaire consisting of self-efficacy scales (Bandura, 1995) and social support and life-satisfaction scales developed by the present researchers. LISREL analyses fully supported Hypothesis 1 and partially supported Hypothesis 2. First, spousal social support had a direct and positive effect on family life-satisfaction. Second, self-efficacy had a mediating effect between spousal social support and family life-satisfaction. Those respondents who received higher social support from spouse had higher self-efficacy, who in turn had higher family life-satisfaction. Third, trust of children did not have a direct effect on family life-satisfaction. Fourth, trust of children had a direct and positive effect on self-efficacy, which in turn had a direct and positive effect on family life-satisfaction. The results indicated that those respondents who had higher trust of children, had higher self-efficacy, who in turn had higher family life-satisfaction. Self-efficacy plays an important mediating role in increasing Korean adults' family life-satisfaction. This study reveal the importance of indigenous psychology in unraveling the factors influencing family life-satisfaction among Korean adults.

Purpose: This study was to examine the effects of intergenerational social support exchange (providing social support, receiving social support) and self-efficacy on the level of depression among elderly women. Methods: A cross-sectional survey design was used. The participants were 247 elderly women, over 60, living in Seoul. Data were collected by convenience sampling using self-reported questionnaires that consisted of items on general characteristics, depression, intergenerational social support exchange and self-efficacy. Data were analyzed with descriptive statistics, t-test, ANOVA, correlation, and multiple regression. Results: Self-efficacy had the greatest impact on the level of depression among elderly women, followed by perceived health status and providing social support toward adult children. The model explained 39% of the variance. Conclusion: Results of the study suggest that as a way to prevent depression, the health administration needs to develop programs to enhance self-efficacy and to promote the supportive role of elderly women within the family.

This study was aimed at (1) investigating expectant mothers' prenatal attachment according to variables (age, gestational weeks, perceived health condition, anticipating the gender of the fetus, marriage duration, and parity), (2) analyzing correlations among their prenatal attachment, spousal support, and parenting efficacy, and (3) examining the role of prenatal attachment as a mediator between spousal support and parenting efficacy. For this purpose, 221 expectant mothers living in Seoul completed a 55-item survey. The collected data were analyzed by t-test, one-way ANOVA, Pearson's correlation coefficients, and regression analyses. The findings of this study were as follows. First, among the variables, gestational weeks, perceived health condition, marriage duration, and parity showed significant differences in the scores for the overall prenatal attachment and subordinate factors. Second, there were positive correlations between the expectant mothers' prenatal attachment and spousal support and between their prenatal attachment and parenting efficacy. Third, the expectant mothers' prenatal attachment proved to mediate between spousal support and parenting efficacy. These findings shed light on the significance of prenatal attachment and spousal support during the pregnancy period; therefore, it is essential to develop education programs for expecting parents to enhance prenatal attachment and spousal support and to conduct follow-up studies to verify the effectiveness of the programs.
