The 2015 revised curriculum offers elementary students an unplugged computing education as a way to learn the concepts and principles of computer science in an easy and fun way and to improve their computational thinking. Yutnori is a traditional board game unique to Korea, which contains various contents such as history, culture, and science of our people, which helps to cultivate cultural identity of learners, and can effectively promote cooperation and communication among members. In this paper, we examined the possibility that Yutnori could be used as an unplugged computing tool in elementary school software education and convergence education. Korean traditional board game Yutnori has elements that can learn the sun and movements of heavenly bodies as well as sequential, selection, and repetitive algorithm elements. Unplugged activities that apply Korean traditional culture Yutnori is expected to help foster creative convergence talents by improving elementary school students' computational thinking, communication and community.

In the past, computer programming was a course taken by students of computing domain majors. With the advent of the fourth industrial revolution, students in all major fields are taking it as the general required course. However, students have difficulties in learning new subject such as unfamiliar computational problem solving approach and general purposed programming language, which can lead to negative phenomena such as learning effectiveness, confidence, and decreased interest. In this paper, the causes of difficulties experienced by non-majors students while learning programming language are analyzed and identified through qualitative and quantitative research on questionnaires, journals, and achievements. Thus, we suggest that designing an educational plan that minimizes difficulties.

유비쿼터스 환경은 조직의 구조와 개인의 행위를 변화시킬 뿐만 아니라 기업의 경쟁 패러다임 자체를 변화시킬 것으로 전망하고 있다. 또한 유비쿼터스 컴퓨팅의 기술이 경영경제, 행정, 교육, 문화, 의료등 사회 전반에 걸쳐 도입되고 있으며, 이에 따른 비즈니스 모델에 대한 중요성이 증대되고 있다. 기술에 관련된 RFID, USN, 표준화, 보안등에 대한 연구가 활발히 이루어지고 있으나, 비즈니스 모델에 관련된 연구는 미흡한 실정이다. 본 연구에서는 유비쿼터스 컴퓨팅에 대해 알아보고 비즈니스 모델 사례 검토를 통해 유비쿼터스 컴퓨팅 시대의 비즈니스 모델과 발전 방향 및 혁신 전략을 제시하고자 한다.

The purpose of this study is to statistically analyze the correlation between unplugged activities using SW educational board games and computational thinking ability of elementary school students, and then find a method of SW education through the results. The study was conducted with 40 students in the 5th grade at an Elementary School in Incheon. Students participated at unplugged activities using a board game for SW education with 12 hours of teacher guidance and 10 hours of free activities. After that, a post-test was conducted to analyze the degree of improvement in computational thinking ability. As the results, it was confirmed that the comprehensive computational thinking ability was improved, and that the four areas of the sub-domains of computational thinking ability were improved to a significant level. These results suggest that providing a basic SW education experience by utilizing a board game for SW education helps to improve students' computational thinking ability.

This study is an example of the education of block coding and physical computing teaching tool for preservice teachers at the college of education. The students were familiar with coding and improved their coding skills in solving various problems through 'Entry' that support block coding. In addition, the students configured the computing system with various input / output devices of the physical computing teaching tool and controlled things through programming and produced the educational portfolio to experience the whole process of problem analysis, design, implementation, and testing in coding. We applied Flow based coding and Pair programming as the teaching methods, and the results of the survey to measure the effectiveness of the study show that students have a good understanding of the entry and physical computing teaching tool and using the combination of the entry and physical computing teaching tool were more effective in learning than the Entry-only coding. In addition, it was confirmed that the effect of Pair programming applied in the physical computing teaching tool.

The goal of this study is to suggest evaluation tools to assess computational thinking(CT) skills in primary robot-based programs. In addition, the researcher has expanded its evaluation approaches to include interpersonal competencies from the socio-cultural perspectives, not just focusing on intrapersonal competencies. In order to pursue the research goal, one-semester robots programs for the fifth graders were designed, and evaluation tools including a learners' CT competencies survey and a learning process monitoring rubric were developed. The results of this study are meaningful because it has expanded the evaluation approaches to connect to the concepts of CT and to include interpersonal aspects from the socio-cultural perspectives.

The purpose of this study is to investigate the effect of software education based on physical computing on the CT ability of elementary school students. To this end, previous studies related to physical computing software education and software education in the 2015 revised curriculum were analyzed. In addition, COBL was selected among many physical computing tools on the market in consideration of the level and characteristics of learners in the school to conduct the study, and 'Professor Lee Jae-ho's AI Maker Coding with COBL' was used as the textbook. This study was conducted for 10 sessions on 135 students in 6 classes in 6th grade of H Elementary School located in Pyeongtaek, Gyeong gi-do. The results of this study are as follows. First, it was confirmed that physical computing software education linked to real life was effective in improving the CT ability of elementary school students. Second, the change in competency of CT ability by sector improved evenly from 8 to 30 points in the pre-score and post-score of computing thinking ability. Third, in this study, it was confirmed that 87% of students were very positive as a result of a survey of satisfaction with classes after real-life physical computing software education. We hope that follow-up studies will help select various regions across cities and rural areas, and prove that real-life physical computing software education for various learner members, including large and small schools, will help elementary school students improve their CT ability.

Today, in the era of the 4th Industrial Revolution, the cloud computing sector has advantages for cost reduction and efficiency of work, but problems related to privacy may arise. Therefore, the law on the development of cloud computing and user protection should be improved to enable providers of cloud computing services to proactively identify whether or not they contain their personal information, or to take steps to protect their privacy. And this same law is desirable to improve the implementation of a national mandatory certification system for privacy protection systems for cloud computing businesses. This same law is also desirable that cloud computing service providers create direct accountability for privacy breaches and appropriate scope for those responsibilities.
