In this study, the meta-analysis technique was applied to investigate the effectiveness of gifted-mathematics programs on development of creativity. Studies conducted the outcomes form the 20 studies were used for meta-analysis. Research questions are as follows; first, what is the overall effect size of the gifted mathematics programs on development of mathematical creativity. Second, what are effect sizes of sub-group(fluency, flexibility, originality) analysis. Third, compare the effect sizes of those in compliance with the grade and the class type. Results from data analysis are as follows. First, the overall effect size for studies related the gifted-mathematical programs was .66, which is high. Second, it was found that each sub-group differed from its effect on learning outcomes. Fluency(.76) was the highest of all, which was followed by flexibility(.60) and originality(.50) in a row. Lastly, the overall effect size for gifted elementary school students related the gifted-mathematical programs was .69, which is high than gifted middle school students was .46.

This study intends to analyze didactically on triangle-determining conditions and triangle-congruence conditions. The result of this study revealed the followings: Firstly, many pre-service mathematics teachers and secondary school students have insufficient understanding or misunderstanding on triangle-determining conditions and triangle-congruence conditions. Secondly, the term segment instead of edge may show well the concern of triangle-determining conditions. Thirdly, when students learn the method of finding six elements of triangle using the law of sines and cosines in high school, they should be given the opportunity to reflect the relation and the difference between triangle-determining situation and the situation of finding six elements of triangle. Fourthly, accepting some conditions like SSA-obtuse as a triangle-determining condition or not is not just a logical problem. It depends on the specific contexts investigating triangle-determining conditions. Fifthly, textbooks and classroom teaching need to guide students to discover triangle-deter-mining conditions in the process of inquiry from SSS, SSA, SAS, SAA, ASS, ASA, AAS, AAA to SSS, SAS, ASA, SAA. Sixthly, it is necessary to have students know the significance of 'correspondence' in congruence conditions. Finally, there are some problems of using the term 'correspondent' in describing triangle-congruence conditions.

The aims of this study is figure out the characteristics of justification patterns and mathematical representation which are derived from 14 mathematically gifted middle school students in the process of solving the spatial tasks on Archimedean solid. This study shows that mathematically gifted students apply different types of justification such as empirical, or deductive justification and partial or whole justification. It would be necessary to pay attention to the value of informal justification, by comparing the response of student who understood the entire transformation process and provided a reasonable explanation considering all component factors although presenting informal justification and that of student who showed formalization process based on partial analysis. Visual representation plays an valuable role in finding out the Idea of solving the problem and grasping the entire structure of the problem. We found that gifted students tried to create elaborated symbols by consolidating mathematical concepts into symbolic re-presentations and modifying them while gradually developing symbolic representations. This study on justification patterns and mathematical representation of mathematically gifted students dealing with spatial geometry tasks provided an opportunity for understanding their the characteristics of spacial geometrical thinking and expending their thinking.

This study aims to review the differences and distinctive characteristics between storytelling method of virtual reality contents and storytelling method of conventional contents instead of focusing on economic and industrial effects of virtual reality contents. As a specific target, this study discusses how existing storytelling method of webtoons as a single contents genre can be applied to virtual reality contents when webtoons are adapted into virtual reality contents. The purpose of this study is to find limitations and possibilities for the storytelling technique of virtual reality contents. The results of this study showed that the essence of storytelling in virtual reality contents is in three roles of the users of virtual reality. The users of virtual reality must play the roles of service user, audience of contents, and director of story. This is because the most important storytelling techniques in media contents like editing and change of camera viewpoint can no longer be forced in virtual reality contents. Storytelling techniques in virtual reality contents are much limited compared to the conventional contents in terms of user interaction, expansion of senses, and guarantee of freedom.

This study is a clinical single case study of the application of Theraplay approach for the treatment of children with eating disorder based on Polyvagal Theory. The first research question is how children with eating disorder change through Theraplay. The second research question is to analyze what the therapeutic factors are for changes in children with eating disorder. To do this, I used a qualitative case study method that explores a small number of cases closely and reveals the case deeply. As a result, the client has a sense of security in Theraplay session, expands the window of tolerance and develops a social engagement system. Through these, client become increasingly adaptable and overcome eating disorder. The results of this study can contribute to neuroscience validation of the counseling effect.

Strengthening self-directed learning ability is established as one of the goals of gifted education in Korea. In addition, it should be noted that self-directed learning can be realized in variety of ways as favorable conditions and environments are fostered to provide gifted education utilizing program. in the recent days. But, gifted learning programs for programming are programmed for information gifted student. Therefore, we have analyzed in this study the effects of improvement on self-directed learning ability of mathematically gifted student through class utilizing app inventor program for self-directed learning ability. Built up from the 4th and 5th grade to elementary math one class for gifted children complete by making math quiz, we use the app inventor to activity. The result of experiment showed very significant difference in the post-survey to less than .002 in the pre-survey in terms of three domains, which are intrinsic motivation, the openness of learning opportunities and autonomy which corresponds to sub-elements of self-directed learning ability. We could verify from the result of the study that mathematically gifted student learning program utilizing app development activity have positive effects on self-directed learning ability of mathematically gifted students.

Through this thesis, I analyzed Coen brothers's directing style centering around Crime movies: Blood simple, Barton Fink, Fargo, The man who wasn't thers, No country for old man. About directing style of Coen brothers, plot is an epic depiction, habitual use of narration, refusal of happy ending. They concern subject matters about human original nature and tragedy by greed. And as motifs, they often use misunderstanding, crossing over, chase. Also they likes characters of ordinary people who is destroyed by greed. How about their technical style? They usually use steady-cam and wide lens in camera, and in his early crime movies he used expressionistic lights, but after that they usually used realistic natural lights. About sound, they likes more sound effects than music. Also they directed realistic acting and emphasized actor's personality. Coen brothers has been directed many crime movies and comedy films. But their unique directing style was particularly outstanding in the crime movies

The purpose of this study was to examine what kind of changes adolescents experienced in the process of returning from the school dropout. For this purpose, 'Qualitative Meta-Analysis' was conducted for seven papers of this area, which was published in Korean journals as a method. 'Qualitative Meta-Analysis' is a method of presenting new interpretations by synthesizing qualitative studies on the same topic. In this study, the qualitative research on the process of returning from the school dropout was selected. The final articles selected for the analysis were seven articles published in domestic journals. The results obtained by comparing and analyzing the selected individual papers were as follows. For adolescents, a series of the process of returning from school dropout was 'self-growth through introspection and support.' In this process, there were five stages of change: abandonment, drifting, self-awareness, decisive action, and struggles. Relevant factors that led to this change were self-perception, the awareness of a reality, resources and support. Based on these results, the characteristics of each step were explained and discussed. Finally, the implications and limitations of the study were clarified and the follow-up study was proposed for more detailed examination.
