  • Although research using meta-analysis is increasing in the field of rehabilitation science, not all meta-analytical papers are of the same quality. In particular, although meta-analysis is a research method with the highest level of evidence, it may be possible to derive distorted conclusions or alternatives by simply integrating representative values without considering heterogeneity among individual studies. This study analyzed the current status of meta-analysis papers on the subject of language arbitration published in Korea from January 2010 to June 2019, and used A Measurement Tool to Assess the Methodological Quality of Systematic Review (AMSTAR). As a result of evaluating the methodological quality of the final five papers, the average of 7.4 points out of 11 points was found above average. In order to raise the qualitative level of Meta-analysis in speech-language pathology in the future, it is necessary to include verification of publication bias and specification of conflicts of interest.

  • The purpose of this study was to discuss the papers of social welfare field that were published in Korea, from a research methodology aspect in accordance with the meta-analysis reporting standard proposed by the United States Psychological Association. To this end, an analysis was conducted according to 5 types of conformity (title and abstract, introduction, methods, results and discussion) on the target subjects of 26 meta-analysis papers of social welfare field. The analysis results showed, first, the conformity in the title and abstract showed good results except for the suggested topics for meta-analysis methods. Second, in terms of the conformity of the introduction, the descriptions seemed to be good in a number of items. Third, for the conformity in the methods, the overall reporting standard was seen to be lacking and, in particular, the reporting standard for the coding procedure was seen as being very deficient. Fourth, the conformity in the results showed that the assessment of research quality and the magnitude of efficacy for each individual study, sample size, and the contents of the provided tables, summary of tables and graphs, including the study results, were not being properly reported. Fifth, the conformity in discussions was seen to be generally sound. Based on such results, by providing a reporting standard and perspective needed for ensuring feasibility that can be used to assess meta-analysis study materials, this study was aimed at presenting implications for the academic advancement of field of social welfare.

  • In this study, the meta-analysis technique was applied to investigate the effectiveness of gifted education in non-cognitive areas. Studies conducted during the years from 2002 to 2012 were searched and then the outcomes from the 18 studies were used for meta-analysis. The statistically positive effects were in the leadership programs (the combined effect size=1.226, p<.001), in the career programs (the combined effect size=1.103, p<.001), in the programs related to social skills (the combined effect size=1.684, p<.001), in the programs for gifted students who show underachievement (the combined effect size=1.486, p<.001), and in the bibliotherapy programs (the combined effect size=0.613, p<.001) for the gifted. Implications of the study were discussed in depth based on the results.

  • The purpose of this study is to conduct a meta-analysis of the research studies between the year 2000 and 2013 on the gender difference of the subjective-welling of Korean older adults. 74 research studies that meet the criteria are analyzed with SPSS and Meta-analysis macros. Results indicated that Korean elder men are better off in terms of subjective well-being (es = .1157, CI95% .0528-.1787) than women. No moderating effects are found. Few studies examined the interaction between the gender difference effect and main factors such as health and social relationship that affect subjective well-being. Based on the results some implications for future research are discussed.

  • As the information and communications market goes more uncertain, foresight activities becomes more important. A number of foresight activities, such as trend analysis, have been used to predict customer needs. However previous studies tend to lack objectivity and systematization. In this study, we suggest a meta analysis methodology which combines both top-down and bottom-up approach in order to systematize the analysis process. Secondly, we applied this approach to ICT market to identify essential future technologies. Based on the result from the meta analysis, we have constructed the future technology roadmap.

  • The purpose of this study is to synthesize and specifically analyze the effects of elementary SW-STEAM Education on learning outcomes by using meta-analysis. 29 papers are selected and total of 60 effect sizes are deduced. Total effect size is a medium effect of .35, which reveals significant effect on the cognitive and affective domains, and 8 moderator variables explain the difference in total effect sizes as well. The results show that SW-STEAM education is effective for elementary students' learning outcomes. Practical implication for design and implementation are addressed.

  • 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.

  • We examined the heterogeneity in the financial -environmental performance nexus, carrying out a meta-analysis of 48 outcomes from 26 empirical studies. Multiple correspondence analysis (MCA) was performed in this study to facilitate the analysis of the structural relationship among an array of study characteristics. As expected, the results of analyzing the multiple studies of the general corporate environmental performance and financial performance link suggested a significant positive relationship. Some of the results of the moderator analysis suggest that empirical studies using self-reporting measurement and structural equation method benefited from environmental performance as much as or more than the archival and regression method.
