In the modern artificial intelligence society, the goal of education is to cultivate convergent talents who can adapt well to and lead the artificial intelligence society. The core competency required of convergent future talents is to be able to understand and create software well. In this respect, algorithmic education is very important. Therefore, in this study, an algorithm education program was developed to improve convergent thinking ability. The effectiveness was verified through the paired samples t-test by conducting a pre-post test of convergent thinking ability, and it was found that students' convergent thinking ability was significantly improved in the areas of algorithm knowledge and function.

As the age that importance of convergence is bigger develops, there is growing different tries and changes in the education sector to train talents necessary for the future age. This paper is aimed at applying gamification factors that can attract elementary school students to participate in classes and cause interests as well as developing a STEAM program for elementary school students. Also, the purpose of this article is to propose educational values and possibility of the STEAM program which gamification factors applied to, and effective methods. For doing this, first, we conducted a study in relationship between the theological background and education on gamification factors based on literature surveys. Second, the STEAM program for elementary school students applying gamification factors and a program called 'My Little Building Forest' were developed. We made three-step contents for classes and activities and textbooks and kits and others with a theme, "principles of the cognitive science on depth perception". Third, developed programs apply to real classes as demonstrating them. We analyzed results through surveys on levels of satisfaction and interviews for teachers and others. Fourth, we discuss possibilities and values and limitations and others on the STEAM program applying gamification factors as we are based on results of analysis. We hope that we maximize impacts of the STEAM education through this education and contribute to train talents to lead age of the convergence.

Media convergence is prevalent all over the world, and is expected to change our lives dramatically in near future. Chaos theory is a new emerging theoretical approach to various social phenomena including organization management, economic system, stock market fluctuation, and so on. This thesis is intended to explain media convergence phenomena centered on internet media using basic concepts of chaos theory such as self-organization, co-evolution, and feedback loop. The implications of this tentative study are that we can apply chaos theory to media convergence as other social or natural phenomena, and that maintaining chaos state of media system is useful for accelerating creativities, and that developing media system as an organic system to cooperate with other relevant systems is helpful for promoting life qualities, and that establishing moral order or root value is desirable for implementing communicatopia.

This study was to verify the effects of education in expression activity and various convergence education found in the class scene of one elementary school man teather to research of qualitative pattern and analyzes how it is expanded. This study were made through two class participation observation and six video analysis. In addition, we measured in-depth interviews of participants and students, a 10-week jump band training program, and applied a step-by-step physical activity program to enhance creative expressiveness. Based on the results of the study, the conclusions are as follows. First, It was found that the Jump-band training positively affects the students' speed, agility, and cardiopulmonary endurance. Second, It was found that the application of the step-by-step physical expression activity program had a positive effect on the students themselves. Third, It was found that it has an educational effect on the whole life of students beyond the curriculum and the field by attempting various fusion education. Based on this study, we propose the educational effects of the pre - curricular activities and the convergence lessons in elementary school during the follow - up research.

This study academically examined about whether STEAM education is really needed, as part of the convergence-style gifted education for training a producer in creative knowledge, through the documentary and Delphi survey. Based on the results, it developed STEAM education materials available for being applied to the domestically gifted education field, and examined the field applicability of the developed program. As a result of surveying validity and class satisfaction, the STEAM education materials of having been developed through this study were indicated to be useful in the aspects of the appropriateness for teaching-material composition, the learning satisfaction, and the promotion in the convergence-based thinking ability. The currently domestic situation is in being short of fundamental discussion about necessity or direction of STEAM education for gifted student, compared to an effort for emphasizing and activating policy of convergence-based education focusing on STEAM. Hence, the outcome of this study, which was performed on the basis of basic research on STEAM education for the gifted student, has significance in the aspect as saying of expanding applicability of STEAM education as the gifted education program.

고성능 양자 컴퓨터가 개발될 것으로 기대됨에 따라 잠재적인 양자 컴퓨터의 공격으로부터 안전한 양자 후 보안 시스템을 구축하기 위한 연구들이 진행되고 있다. 대표적인 양자 알고리즘인 Grover 알고리즘이 대칭키 암호에 적용될 경우 보안 강도가 제곱근으로 감소되는 보안 훼손이 발생한다. NIST는 대칭키 암호에 대한 양자 후 보안 요구사항으로, 암호 알고리즘 공격에 요구되는 Grover 알고리즘 비용을 기준을 기준으로 양자 후 보안 강도를 추정하고 있다. 대칭키 암호를 공격하기 위한 Grover 알고리즘의 비용은 대상 암호화 알고리즘의 양자 회로 복잡도에 따라 결정된다. 본 논문에서는 NIST 경량암호 공모전 최종 후보에 오른 Sparkle 알고리즘의 양자 회로를 효율적으로 구현하고 Grover 알고리즘을 적용하기 위한 양자 비용에 대해 분석한다. 마지막으로, NIST 양자 후 보안 요구사항과 분석한 비용을 기반으로 경량암호 Sparkle에 대한 양자 후 보안 강도를 평가한다. 양자 회로 구현 및 비용 분석에는 양자 프로그래밍 툴인 ProjectQ가 사용되었다.
