The purpose of this study is to confirm the effect of health assessment classes applied with flip learning on self-directed learning ability, critical thinking disposition, and academic self-efficacy of nursing students. This is a comparative study before and after a single group, targeting sophomore students taking a health assessment by applying flip learning at a nursing college in K city, Gyeongsangbuk-do. The final analysis consisted of 104 subjects, and the pre-post difference was analyzed by a paired sample test. As a result, self-directed learning ability (t=-3.23, p<.01), critical thinking disposition (t=6.381, p<.001), and academic self-efficacy (t=-4.62, p<.001) were all statistically significantly increased. Based on the results of this study, it was confirmed that the flip-learning method is an effective program to enhance the self-directed learning ability, critical thinking ability, and academic self-efficacy of nursing students. In the long run, the application of the flipped learning learner will play a role in improving the educational environment and strengthening the abilities of students.

Purpose: This study examined the relationship among the use of food-related content (FRC), dietary behaviors, and dietary self-efficacy to demonstrate the need for nutrition education to help adolescents build healthy eating habits and provide evidence for developing nutrition education programs for adolescents. Methods: Three hundred and eighty-one high school students in Seoul and Gyeonggi areas participated in the study. The subjects were divided into three groups (low, medium, and high) according to the level of use of the FRC, and their general characteristics, dietary behaviors, and dietary self-efficacy were analyzed. Correlation analysis was performed between FRC usage, dietary behaviors, and dietary self-efficacy, and the mediating effects of dietary self-efficacy on the relationship between the level of the use of FRC and dietary behaviors were estimated. Results: A higher level of FRC usage was associated with an increased daily cost of eating out and snacking, but no difference was observed in the BMI range. The subjects in a group with a high level of FRC usage ate convenience store or instant foods instead of homemade meals (p = 0.033), had a late-night meal or snack (p = 0.024), and turned to emotional eating under stress (p < 0.001) more than those in the low level group. In addition, the high level group checked the nutrition facts label more carefully when purchasing processed foods (p = 0.016) and exercised at least 30 minutes daily, not considering physical education classes (p = 0.057). The higher level of FRC use, the lower the dietary self-efficacy, whereby the subscales 'environmental stimulus control efficacy' and 'affective factor control efficacy' showed complete mediating effects. Conclusion: Given that FRC has been increased recently, adolescents are in need of support to help them control and enhance their dietary self-efficacy as well as develop healthy dietary behaviors through proper nutrition education programs.

This study was proposed in obtaining basic data for an intervention programs of the stable child care by identifying the effects of support from the spouse and family on the child rearing among marriage immigrant women. Subjects consisted of 110 marriage immigrant women in Gyeonggi-do in December, 2014. SPSS/WIN 22.0 program was used for ANOVA, Pearson's correlation and multiple regression analysis to figure out burden and efficacy of child rearing through the general characteristics. The increased burden of child rearing was statistically significant with young age, lower level of education, low income and less spending time to raise their children by husband. Additionally, the increased efficacy of child rearing was statistically significant with young age and using two languages. The pressure of the child rearing showed a negative correlation with spouse support, income, and old age. The efficacy of child rearing had a positive correlation with spouse support, spending time to take care of their children by family, and ages. In the regression analysis, the burden of child rearing among immigrant women increased by old age (${\beta}=-2.097$, p<.05) and less time to raise their children by husband (${\beta}=-2.165$, p<.05). It is important to provide spouse and family support to encourage desirable child rearing behavior. These results may provide to improve intervention programs for child rearing among marriage immigrant women.

This study investigated the relationship between pre-service early childhood teacher's metacognition and emotional intelligence on character development efficacy. The subjects were 218 pre-service early childhood teachers at university. A questionnaire, which required self-reporting by these teachers, was used to investigate the effect of their metacognition and emotional intelligence on character development efficacy. The data were analyzed by Pearson's correlation and stepwise regression. The study results were as follows. First, metacognition and emotional intelligence exerted an effect on the character development efficacy of pre-service early childhood teachers. Second, there were significant positive correlations between the metacognition and character development efficacy of the teachers. Third, there were significant positive correlations between the emotional intelligence and character development efficacy of the teachers. Fourth, emotional comprehension of others, emotional comprehension of own, error correction, and emotional activity were meaningful and influential variables on the teachers' self-leadership. These results increased the perception for the development of pre-service early childhood teacher curriculum about character development efficacy, metacognition and emotional intelligence of pre-service early childhood teachers.

BACKGROUND/OBJECTIVES: Childhood obesity has increased in recent decades in Korea. This study was designed to examine differences in the eating habits, physical activity (PA), nutrition knowledge, and self-efficacy of children by obesity status. SUBJECTS/METHODS: Subjects were 5th-grade children from 70 elementary schools in 17 cities nationwide. Two-stage stratified cluster sampling was employed. Survey questionnaire included items related to general characteristics, eating habits, PA, nutrition knowledge and self-efficacy. Excluding incomplete responses, 3,531 data were analyzed using SPSS. Subjects were categorized into overweight obesity (OW) and normal weight (NW) groups based on body mass index percentiles for age by sex. RESULTS: A total of 21.5% of subjects was overweight or obese. There were significant differences in gender, perceived stress, perception of body shape, body satisfaction, and interest in weight control between the OW and NW groups (P < 0.001). With respect to eating habits, the OW group ate breakfast (P < 0.05) and snacks (P < 0.01) less frequently, ate bigger meals (P < 0.001), and demonstrated less desirable behaviors during meals (P < 0.05 in boys) compared to the NW group. The OW group participated in less PA than the NW group, especially boys. OW boys spent less time walking during weekdays (P < 0.05) or the weekend (P < 0.001), spent more time being sedentary during weekdays or the weekend (P < 0.001), and exercised a fewer number of days (P < 0.01). For girls, the OW group spent more time being sedentary during the weekend (P < 0.01) and exercised a fewer number of days by walking or bicycle riding (P < 0.05) than the NW group. Nutrition knowledge was not significantly different between the OW and NW groups. Self-efficacy (P < 0.01 in boys), especially PA self-efficacy (P < 0.01), was significantly lower in the OW than NW group. CONCLUSIONS: This study revealed differences in eating habits, PA, and self-efficacy between OW and NW children. Obesity management programs for children need to focus on increasing self-efficacy, modifying eating habits, and increasing PA.

This study has tried to find the gap of health promoting behavior and the lower level-health responsibility, physical activity, self-actualization, stress management and self-efficacy-between new freshmen and other university students in dormitories who have taken health education as an elective course through health education. With 105 students conducted self-answering survey. It was conducted from June 12 to June 13 of the year 2013. Analysis has been conducted into 5-point scale in every parts of health promoting behavior, 4-point scale in self-efficacy. As a result of the study, after health education, the increasing level of the score was bigger than general university students in preceding research before education; from this, we could interpret that the peers who live together lead positive competition. For before-and-after affects of education, after-education score increased statistically significantly higher from before-education score for both freshmen and other students on every item of the survey. Especially, self-efficacy and stress management, which are the lower level of health promoting behavior, have shown statistic significance of health education. When comparing freshmen and other students, the item that showed significant difference was 'self-efficacy,' and for both before and after health education, other students had higher score than freshmen. Based on the result of the analysis, for those who live together with group of people such as in-dorm students, group education is preferred to personal education; in addition, when selecting health education recipients, better achievement of education will be expected by primarily educating students who have lower level of self-efficacy and stress, especially freshmen who have lower self-efficacy level than other students in university.

This study explored the effectiveness of science teaching practice and science teaching efficacy beliefs by development of elementary school teachers' pedagogical content knowledge. Three research questions are formulated: 1) Is there any relationship between the development of teachers' pedagogical content knowledge and the science teaching efficacy beliefs? 2) How does the development of teachers' pedagogical content knowledge affect the science teaching practice? 3) How do the science teaching efficacy beliefs affect the science teaching practice? 120 subjects were chosen in 53 public elementary schools. Quantitative and qualitative data were collected and analyzed to triangulate the results. Results indicate that the development of teachers' pedagogical content knowledge and science teaching efficacy beliefs are more developed in accordance with teachers' teaching career and academic career are increased. There are significant relationships between teachers' science pedagogical content knowledge and science teaching efficacy beliefs. The more the teachers' pedagogical content knowledge, the more confident in science teaching practice. The more the science teaching efficacy beliefs, the more confident in science teaching practice. Also these teachers tried to present teaching objectives and learning problems in the beginning stages of science lessons, and they tried to review each learning stage.

This study examined the developmental trajectories of parenting efficacy of mothers of multicultural families and how these trajectories differentiate perceived mothers' career-related behaviors as well as the socio-psychological and academic characteristic of their children in the first grade of high school. The latent class analysis (LCA) and BCH method were applied by using data drawn from the 4th to 10th graders in 2011-2017 from the Multicultural Adolescents Panel Study (MAPS). Results showed that the latent profiles were classified into four groups based on the developmental trajectories of parenting efficacy of mothers of multicultural family: 'high level increasing-decreasing', 'above average increasing-decreasing', 'average unchanged', and 'below average unchanged'. As for demonstrated outcomes, the high parenting efficacy group increased when children were in elementary school but decreased when children were in middle school. At the same time, the low parenting efficacy group did not show much change during these periods. Next, parenting efficacy was a significant determinant of perceived mothers' career-related behaviors and socio-psychological and academic characteristic of their children who attend high school. Based on these results, this study implies a theoretical foundation for developing policies to encourage parenting efficacy of mothers of multicultural families and may result in positive socio-psychological and academic characteristics of their children in high school.

This study examines the relationship between teacher-perceived teaching efficacy and happiness and teacher-infant interaction, and analyzes the effect of teaching efficacy and happiness on teacher-infant interaction. The purpose was to reveal that it was an important variable in the quality of action. Frequency analysis and descriptive statistics analysis were conducted for the Korean Children's Panel 7th year (2014) data, and Pearson's moment-moment correlation coefficient was calculated for correlation analysis between variables. Multiple regression analysis was conducted to examine the influence of teachers' teaching efficacy and happiness on teacher-infant and infant-infant interactions. The research results were as follows. First, teachers' teaching efficacy, teacher happiness, teacher-infant, and infant-infant interactions were all found to have significant positive correlations. Second, teachers' teaching efficacy was found to have a significant effect on teacher-infant and infant-infant interactions, and the influence increased when teacher's happiness was added. Therefore, we need to come up with a plan to increase teachers' teaching efficacy and teacher happiness at the same time so that the quality of teacher-infant and infant-infant interactions can be meaningfully improved.
