A Meta-analysis refers to a statistical literature synthesis method from the quantitative results of many known empirical studies. We conducted a meta-analysis and review of external factors based on the technology acceptance model for Smartphone-related researches. This study surveyed 106 research papers that established causal relationships in the technology acceptance model published in Korean academic journals during 2008 and 2013. The result of the meta-analysis might be summarized that the playfulness has the highest effect size in the path from external factors to the perceived usefulness, with the effect size(0.536). Also the self efficacy showed the highest effect size(0.626) in the path from external factors to the perceived ease of use. Based on these findings, several theoretical and practical implications were suggested and discussed with the difference from previous researches.

This modern society is said to be more typical of an emotional society. In such a society, emotional design adds value to products, hence bringing about value-enhanced products. Despite many claims of little substance about emotional design, there have been only a few researches that have identified what criteria to be applied to distinguish between emotional products and generic products or even have clearly defined what emotional products are. This leads to a clear need for providing more definite criteria for defining and classifying design elements useful and available for users. To fill the gap, the purpose of this study is, first, to explore the relationship between evaluation elements for creative design and emotional design, and, based on that, identify some of the most importantly valued elements, and secondly, to examine how the images importantly used for expression relate to creativity evaluation elements according to classified types of design. In this study, chosen products were presented to selected users so that they can choose what they think possesses emotional design elements. Then the products so chosen were classified according to design type for examination of their respective relationship with creativity evaluation elements. In addition, the identification was performed of perceived design images about the selected products and the relationship between those images and creativity evaluation elements. This study is expected to provide a chance to be aware of the fact that essential creativity evaluation elements can vary depending on changing times, environments, and users, and as well, to offer an insight into what images design should be possessive of for it to be preferred by consumers.

A meta-analysis is a statistical literature synthesis method that provides the opportunity to view the research context by combining and analyzing the quantitative results of many empirical studies. The technology acceptance model (TAM) has been the subjects of a great deal of MIS research in the last two decades and now also has been continuously studied. Recently, the convergence of knowledge information society and information telecommunication technologies has a rapid impact on politics, economics and various fields. The biggest issue in the information communication and information systems fields is smart. Therefore, we conducted a meta-analysis research on the behavioral intention of smart phone users based on technology acceptance model. Also, this study was targeted a total of 50 research papers that are setting up the causal relationship in TAM among the research papers published in domestic academic journals since 2005. The result of the meta analysis, showed that the effect size was 0.48 in the path from perceived usefulness to behavioral intention, it showed that the effect size was 0.46 in the path from perceived ease of use to behavioral intention. And, it showed that the effect size was 0.46 in the path from perceived ease of use to perceived usefulness. Also, it showed that the effect size was 0.61 in the path from attitude to behavioral intention. Based on the results, it was discussed the difference through comparative analysis with previous research.

This study explored to what extent Korean science teachers perceived socioscientific issues (SSI) as an effective instructional tool for creativity and character (CreActer) education; which was recently announced as a main goal for the Korean National Science Curriculum 2009. The guiding research questions were as follows. (1)How do science teachers conceptualize the relationship between creativity and character in the context of science classes? (2) What do science teachers think about the possibility of CreActer education through SSI in science classrooms? Thirty science teachers participated in individual interviews (each lasted 20-90 minutes). In the results, the teachers' perceptions on CreActer education and SSI for CreActer education were categorized into four profiles. Eleven teachers in Profile A thought that creativity was positively correlated with character education because their understanding of creativity and character embraced a very broad range of elements. They mentioned that addressing SSI in the science classes would be satisfactory to cover those elements of CreActer education. Six teachers in Profile B mentioned similar elements of creativity and character of Profile A, but reported that, in their experience, creativity was often inversely correlated with character. However, they responded that addressing SSI would be a good way to integrate creativity and character in the science classes. Ten teachers in Profile C believed there was no relationship between creativity and character, but took a positive stance on CreActer education through SSI. Unlike Profile A and Profile B, they tended to regard character as only an interpersonal virtue. And three teachers in Profile D had a narrow perspective on CreActer education. Not only did they think creativity had no relationship with character, but also disagreed that CreActer education would be activated by addressing SSI in science classrooms. The results imply that SSI could be used as an effective instructional tool for CreActer education, but this can be possible when science teachers expand their view on CreActer education.

Meta-analysis is a statistical integration method that delivers an opportunity to overview the entire result by integrating and analyzing many quantitative research results. This study will find meaningful mediator variables for criterion variables that affect purchase and repurchase intentions in e-commerce, on the basis of the results of a meta-analysis. We reviewed a total of 114 e-commerce studies published in Korean journals between 2000 and 2014, where a cause and effect relationship is established between variables that are specified in the conceptual model of this study. In this meta-analysis, the path between trust and purchase intention showed the biggest effect size. The second biggest effect size was found in the path between commitment and purchase intention, while the smallest one was obtained with perceived. Thus, we present the theoretical and practical implications of these results and discuss the differences among these results through a comparative analysis with previous studies.

This research aimed at identifying the influential factors on high school students' dress code compliance. Specifically, the relationship between the perceived strength and importance of dress codes and dress code compliance, and the relationship between dress code compliance and creativity, self esteem, and school adaptation were examined. For this purpose, reliability tests, multiple regressions, and t-tests were conducted using the data collected from 866 male and female students from six Co-Ed high schools located in Seoul. The results are as follows. First, the more students perceived the school dress codes to be stronger and more important, they were more likely to comply to the dress codes. Second, compared to the low-compliance group, the high-compliance group had higher self-esteem and creativity. Third, compared to the low-compliance group, the high-compliance group showed better adaptation to their teachers, classes, and school rules. However, the two groups were not significantly different in terms of their adaptation to peer groups.

The purpose of the study was to verify validity of Creative School Environment Perceptions (CSEP) scale developed based on the scale developed in 2010 by Mayfield and Mayfield. Factor analysis was used to assess construct validity. Another purpose of the study was to investigate factors related to students' perception of creative school environment through use of the group differences. The research participants were 203 elementary school students and all of them were 5th and 6th grade students. Factor analysis indicated that CSEP scale consist of three factors: creativity support, work characteristics, and creativity blocks. In addition the correlation between CSEP scale and the previous scale were investigated to verify the validity of CSEP scale. The results showed that the convergent validity were obtained. Independent-sample t test was performed to test for specific loci of significant between group differences in gender, grade, and the level of ideational behavior. The finding showed that 6th grade students said that their environment hinder creativity. Students with the high level of ideational behavior perceived their school environment was supportive while students with the low level of ideational behavior perceived their school environment was obstructive. Therefore teachers should understand students' perception of creative school environment using CSEP scale and should change students' perception of creative school environment through considering grade and the level of ideational behavior.

In National Curriculum of Science revised in 2007, free inquiry was newly introduced to increase student's interest in science and to foster creativity by having students make their own curiosity questions and find answers by themselves. The purpose of this study is to analyze elementary school students' perceptions on free science inquiry activities applying a brain-based evolutionary approach. For this study, 106 the fifth grade students participated, and then completed a questionnaire on free inquiry activities according to a brain-based evolutionary science teaching and learning principles. The students performed a series of steps of the Diversifying, Estimating-Evaluating-Executing, and Furthering activities in each of Affective, Behavioral, and Cognitive domains (ABC-DEF approach) and constructed their own free inquiry diary, then the observations by the researcher and interviews with the students were analyzed both quantitatively and qualitatively. The major results of the study were as follows: First, the majority of the students perceived the each domain and step positively although a few of them perceived negatively. The reasons perceived as negatively were categorized into two; preference dimension of like or dislike and ability dimension of metacognitive or self-reflective capacity. Also, they perceived the free inquiry experience in the form of ABC-DEF as helpful to understand the nature of scientists' scientific activities. Based on these findings, implications for supporting authentic inquiry in school science are discussed.

For developing the Group Health Care System, health managers' job structure were analysed in the aspects of content, amount, and process. As a trial research, data were collected by a standardized job analysis table to 6 doctors, 40 nurses, and 11 industrial hygienists of Group Health Care System. Health care managers were performing complex and intellectual jobs such as healh education for workers, managing health care, conference as well as more simple jobs like as filling diary. Especially, job was consisted of general job and health care management job in the proportion of 1:2.18. The major general job were data management related with the health statistics, and major health care management jobs were managing health care, health counselling, environmental management of working sites. Each specific jobs were required differentiated intellectual capacity, creativity, autonomy, psychic stress, and physical work; most respondents perceived that health care management jobs should require more inputs than general jobs. Additionally job satisfaction and perceived need on specific Job items were anzlysed. Results of this research, suggested through the field experiences in working sites, should be considered for improving the Group Health Care System.
