The purposes of this study is to analyze gender difference in predictors of mobile phone dependency in youth. The analysis is performed with third-year panel survey data of middle school 1st grade students from Korean Child-Youth Panel Survey. The results are as follows. First, the female students' mobile phone dependency is more serious than the male students' mobile phone dependency. Second, while the identified male gender predictors are aggression, parental abuse, aprosexia, study activity and social withdrawal, the identified female gender predictors are depression, aprosexia, aggression, study activity and social withdrawal. Based on these results, theoretical and practical implications in planning of prevention or intervention of mobile phone dependency are proposed.

The study aims to investigate nocturnal sleep duration in 4-year-olds and relative effects of various factors including the personal factor (temperament), the familial factor (mother's employment status), the time-use factors (hours spent in childhood educare institutions, on napping in the institutions, and on using electronic media). The data of 937 4-year-olds collected by the Korea Children and Youth Panel Survey in 2012 was analyzed. Using SPSS 21.0 program, frequency analysis, descriptive statistics, Pearson's correlation analysis and hierarchical regression were conducted. The results are as follows. First, there were significant negative correlations among the personal factor, familial factor and time-use factors. Finally, the time-use factors showed largest explanatory power on variance of children's nocturnal sleep duration, followed by the familial factor. But the personal factor was not statistically significant. These results suggested that parents and childhood educare institutions need to cooperate in order for children to sleep well. It is also necessary to implement and spread the social systems to support healthy development of children.

The purpose of this study was to conduct a systematic review of the previous studies done on the child-care teacher's turnover intentions. From 2001 to 2011, 33 articles which reforted primary empirical data met the criteria for inclusion in the meta-analysis. The results of this study are as follo ws: First, included in the main factors related to child-care teachers' turnover intentions were a job-related variable, an organizational internal variable and an organizational external variable. Second, the most influential protective variable related to the child-care teacher's turnover intentions among the set of organizational external variables was work-time followed by welfare, education and training, remuneration, social recognition and promotion system. Third, the most influential protective variable related to child-care teachers' turnover intentions among the set of job-related variables was teacher efficacy followed by job satisfaction, participation of decision making, performance, work-autonomy and work-professionalism. Fourth, the most influential protective variable related to the child-care teacher's turnover intentions among the set of organizational internal variables was personal relations followed by relationships with the director and relationships with colleagues. The effect size of these variables was large. Fifth, the results of meta-regression analysis revealed that the survey area and years had no significant effect on overall effect sizes.

This study has examined the structural relationship among factors related to the effects of flipped learning using the structural equation modeling. Two hundred thirty-six middle school and high school students were participated in this study. This study's results are as follows. First, looking through how much the flipped learning variables affect achievement, motivation affects achievement the most, and then interaction, participation come next. Second, looking through how much the flipped learning variables affect personality, interaction affect personality the most, and then teaching attitudes come next. Third, as a result of verifying the research model, the hypothetical model indicating relationship among motivation, participation, teaching attitudes, interaction and achievement, personality is valid.

The objective of this present study was to investigate the overall effects of strategy instruction on Korean students' English language learning. In order to do so, 55 individual experimental results in 46 journal articles were collected, and a meta-analysis was carried out to them. This study also analyzed the results of studies on strategy instruction according to various variables such as school types, treatment periods, and types of dependent variable. The mean effect size of strategy instruction in English language teaching is .536, which means the medium effects in general. No statistically significant differences were found among various moderators and dependent variables. Based on these results, suggestions for further research are discussed.

In order to investigate variables related to the life satisfaction of women from the multi-cultural families, this study collected relevant studies and applied meta-analysis. As a result, it was found, first, their life satisfaction was between the small effect size and the moderate effect size, on the basis of the relevant variables and Cohen's standards(1992). Second, of the sub variables of their individual characteristic variable, Korean proficiency and nationality acquisition were found to be the small effect size. Third, of the sub variables of their psychological variable and multiple culture-related variable, the effect sizes of self-esteem and the receptive attitude towards multiple cultures were found to be between the moderate effect size and the large effect size. Fourth, the sub variables of their social support variable were found to be generally highly correlated with their life satisfaction. Fifth, the sub variables of daily life and spouse-related variables showed very low levels of effect size overall. This study suggested conclusions and limitations of the research based on the results of the above analyses.

The purpose of this study was to compare the ideas of pupils with that of the scientists about controlling and identifying of variables, in the two cases: open or guided inquiry. The subjects were the 7th grade boys and girls in a school, in Seoul, Korea. For the guided inquiry, the problems were given by the experiments of pupils' text. Pupils were asked to identify the variables in the experiments. For the open inquiry, pupils set their own inquiry problem. The pupils whose marks are within upper one-third of three classes were chosen. Pupils' ideas on variables were investigated in the design of experiment for their problems. In that, questionnaire developed by researchers was used. In the former, many of the pupils identify just only one variable despite of the fact there were two independent or dependent variables in the experiments. In the latter, the number of independent variables increased two or three. However, pupils do not control independent variables: they vary two independent variables simultaneously in the design of experiment. From these, we compared the pupils' ideas on variables with the scientists'
