  • Meta-analysis was conducted to examine effects of computer based virtual reality on clinical rehabilitation in Korea. The data were analyzed as the ICF categorizations. The papers used in this study were located through domestic data search engines. The fifteen studies were selected among the studies published between 1995 and 2014. The PEDro score was used for qualitative assessment. The sample size and the average and standard deviations of pre and post tests were analyzed through a meta-analysis. The PEDro scores of the selected studies were 6 points higher and 338 participants were involved. The effect size of combined data was 1.030, activities and participation 1.120, sensory function 1.199 as indicated by a "large effect size" and the effect size of mental function was 0.557 as indicated by a "medium effect size." As a result, virtual reality program as a adjunctive therapeutic methods has proven the effect. In particular, the effects were demonstrated in activities and participation, sensory function. However there was no evidence of the effectiveness of mental function.

  • The purpose of this study was to examine the effectiveness of drama program for early children by using method of meta-analysis. For the purpose of the study, master's theses, doctoral dissertations, and journal articles published in Korea up to April, 2017 were systematically reviewed. As a result, a total of 39 studies were eligible for the inclusion criteria. The mean effect sizes and test for homogeneity of effect size(Q-statistic) were analyzed by using Comprehensive Meta-Analysis software 2.0. The main findings of the study were as follows. First, the average effect sizes for drama program were ES=1.922 of verbal expression, ES=1.898 of emotional intelligence, ES=1.558 of creativity, ES= 1.292 of sociability. Second, by analysing the moderate variables of the effect size for drama program, 'age' of verbal expression, creativity and sociability, 'sessions' of verbal expression were statistically significant. Based on the study results, the research and practice implications were discussed.

  • The purpose of this study was attempted to conduct a meta-analysis on the antecedents factors of transformational leadership of nursing unit managers. Literature was collected according to the PRISMA guidelines, and the antecedent factors of 23 studies were analyzed. The results showed that the total 23 studies large effect size (ESzr=.54). Antecedent factors were classified into three categories, and the organization-related variables group had the largest effect size (ESzr=.56). This study is an integrated presentation of the effect size of the antecedent factors of transformational leadership through a meta-analysis and the results of this study are expected to be used as a basis for developing intervention programs for nursing unit managers' transformational leadership improvement.

  • There have been a number of studies on ports and they have made great contributions to the development of ports. However, there have been no research that classified and organized the results comprehensively. Therefore, this study aims to analyze the results of studies related to Korean port economics. For the purpose, we carried out a meta-analysis targeting 659 articles published in Journal of Korea Port Economic Association from 1991 to 2010. For the meta-analysis on themes of port economics and methods, the study presented a total of three items to be analysed: First, we analysed characteristics of researchers, discussed themes and identified contents by analysing research methods used for the studies. As a result, port economics have shown great growth in volume and recently, more attentions have been paid to ports along with increase of researchers, and themes and methods of research have been sub-categorized and diversified. Therefore, based on the results of the study, comparative studies should be added.

  • The purpose of this study is to conduct a meta-analysis of 18 papers that can be verified among the papers on the subject of TPM. Five hypotheses were set for the analysis and meta - analysis was carried out with CMA as presented in each research paper. As a result of analysis, I-square value is more than 75% in four hypotheses. Therefore, the null hypothesis that the size of the population effect is the same for all studies was rejected. The reason for the heterogeneity is that the research characteristics such as the distribution of the respondents, the study conditions, the study period, and the study area are different. In this case, a summary statistic of the individual studies that can be classified according to the characteristics of the research is needed to analyze the effect size difference. However, individual studies do not provide a summary statistic that can classify the effect differences, so it is not possible to analyze the causes of heterogeneity.

  • The purpose of this study is to use meta-analysis as a research method to investigate the correlation between early child teachers' teaching efficacy and their job satisfaction, and thereby look into the effect size of the two variables and their sub-variables. To achieve the purpose, this researcher chose a total of 37 theses for analysis and collected 289 data for analyzing the effect size. Based on the data, CMA(Comprehensive Meta Analysis) 2.0 was applied. According to the analysis, the correlation between early childhood teachers' teaching efficacy and their job satisfaction was higher than the medium effect size on the basis of Cohen(1992) research. In the sub-variables of teaching efficacy, the correlation of personal teaching efficacy with job satisfaction showed higher effect size than that of general teaching efficacy. In the sub-variables of job satisfaction, the correlation between the belief in job and teaching efficacy showed the highest effect size. In terms of thesis type as a moderating variable, Ph.D dissertations showed higher effect size than journals or M.A. theses. As the result of the meta-analysis on publishing year and the number of samples, there was no statistical significance. On the basis of the analysis results, discussions and limitations of this study were suggested.

  • This study is to identify the effectiveness of English literature in reading instruction using meta-analysis of advanced researches. 80 studies published in Korea were selected for this research wherein the studies are in experimental nature on reading instruction using English literature. The result of the meta-analysis are as follows: Reading instruction with English literature for early children in kindergartens and primary schools showed statistically significant positive effects in both reading abilities and affective domains, in particular for younger children from kindergartners to 2nd graders of primary school. It was more effective when the instructor used top-down approach than bottom-up or balanced approach. No significant coorelation was found between the number of English stories and the students' linguistic ability. Diverse activities tailored to students' need are turned out to be more effective than using same old activities with more stories.

The 54 programs to meet the conditions for meta-analysis were selected using internet search on the homepage of National Digital Library, KERIS, and National Assembly Library and the key words such as 'internet', 'addiction', 'counseling', and 'program' were used for searching the programs. The results of this study were followings: First, the average score of the effect sizes of 54 programs was 1.89 and thus the internet addiction programs had great positive effects on the improvement of adolescent's internet addiction. Second, all the programs' effect size scores showed more than 1.25 except psychological education program. Third, there were no significant differences at the effect size scores among elementary school students' goup, junior school student's group, and high school students' group. Fourth, when programs had more than 6 sessions, the programs showed desirable effect size. Fifth, when programs had were less than 15 subjects, the program's effect sizes were sufficiently great.
