Life competencies most required for university students, who receive a higher education and prepare to go into society, are job competencies. People with a variety of competencies are needed in the job market in a globally-oriented 21st-Century knowledge-based society. Now that raising competent people who have a high level of job competency is regarded as one of university functions, a way to improve job competencies through university education needs to be investigated. This study proposes a convergence education system to improve job competencies. The convergence education system includes five type of convergence: convergence in major fields of study, convergence in education courses, convergence in education space, convergence in education methods, and convergence in education period. This education system is expected to improve a variety of job competencies including cognitive competencies, non-cognitive competencies, and global competencies.

As the convergence solutions become more common, the use of Arduino and Raspberry Pi boards has been increasing. These control boards has to be executed under power blackout. In this environment, we take advantage of solar power system to overcome the power out. In this paper, we poposed a effficient power control strategy. Our experimental device is a DSLR shooting device executed based a predesigned interval time. The control module of our experimental device is the compound system of Raspberry Pi and Arduino boards. Arduino board send the force signals to wake up Raspberry Pi. We developed a new control strategy algorithm for the efficient use of solar power energy. In this paper, we mesured the efficiency of solar enery consuming of our system. We programmed a control system to send DSLR shooting signals. In experimentals, we ensured a stable consuming of electricity during 10 days. In the end, it was found that the consumption power of the Raspberry was reduced by about 81% when the Aduino was combined to save power.

In this study, it was attempted to develop a grade-customized statistical analysis system that can be operated by a teacher without professional knowledge of statistics by utilizing profiling in the education sector. For this, with the convergence of techniques of profiling into the education sector, it examined the elements necessary for building a customized student multidimensional analysis system. Referring to the overall configuration and the current state to build multidimensional analysis system utilizing practical profiling, it showed the implementation result of the algorithm applied to each statistical method, and presented the differences and superiority to existing systems. Once the system based on the proposed techniques is built, considering differences of students' needs and abilities and clarifying precise objectives and standards, with the improvement of satisfaction in public education, it is possible not only to reduce expense of prior and private learning but also realize self-directed learning suitable to one's learning ability and aptitude.

The purpose of this study is to present a block type smart classroom model for comprehensive supply of educational contents, classroom environment and ICT technology in African countries where educational infrastructure is weak. It will provide a contextual solution that integrates learning management, power management, and classroom environment management systems, and will be a convergence model that can optimize economic and non-economic conditions for different African countries. It can be expected to enhance utilization as it is a differentiated model from existing classrooms with a single container, as well as independent research and development centered on services, content, and solutions. Through this integrated research process, we can overcome the spatial and functional limitations appearing in single container classrooms and build a flexible space for advanced e-learning technology. The depth and scope of the follow-up study can be carried by investigating the performance and models that are in line with the educational and infrastructure conditions of the various regions.

정보기술 발전에 따라 정보 활용 및 처리 역량이 상승하면서 교육 환경의 지능화, 네트워크화로 기술간, 서비스 간 융 복합을 통한 다양한 학습 내용 및 방법이 출현하였으며, 최근 e-러닝 산업에서 스마트기기 보급 확산과 상황 적응적이고 자기 주도적 학습에 대한 소비자의 니즈가 증가하면서 새로운 형태의 교육시스템인 스마트러닝이 부각되고 있다. 이러한 교육 패러다임의 변화에 따라 기존의 교육 콘텐츠를 스마트기기에 적용하기 위해서는 콘텐츠 및 솔루션 구조의 개선이 요구되며, 또한 서비스 제공의 측면에서 다양한 교육 콘텐츠 연동과 교육 서비스 융합을 위한 표준 플랫폼 적용이 필요하다. 이에 본 논문에서는 JVM 환경의 PC 인터페이스를 통해 ePub 표준의 교육용 멀티미디어 콘텐츠 제작기능과 기존 서책형 파일 포맷의 자료 정보를 응용하기 위한 정보변환 모듈, 스마트 기기용 ePub 전자책 뷰어를 포함하는 통합 솔루션 소프트웨어인 ePub Solution을 설계하였다.

The purpose of this study is to examine problems and status quo of the smart media addiction prevention system and to develop convergence policies to improve those systems. Based on the literature review, notable results are as following; Since current facilities including Internet Addiction Prevention Center, Korea Youth Counselling and Welfare Institute, and I Will Center, tend to focus on restricting use of smart media, efforts from various ministries have not worked properly. Therefore, there needs to be more specified and customized services based on regions and ages. Following the precedent set by advanced countries, this study suggest alternative policies to help solving the problem including recommending responsible use of social media through education rather than regulations only, encouraging family participation and intervention, expanding harmful environment block system, and establishing a partnership between local government and private organizations under central government's control. Since smart media addiction is emerging concern, further researches will be needed for developing the Korean standard for prevention policy.

A maze-escaping method with cooperating work of robots alongside one another will be proposed in this paper. Educational robots can communicate each other using Zigbee; however, they can't solve problems together due to their lack of arithmetic function. The robots walk upright controlled by a motion program; furthermore, they recognize an intersection or a dead-end in the use of distant sensors with sending data and receiving commands from the central control system. The maze-search algorithms were modified so that all robots can effectively navigate the maze.

This study is to analyze and evaluate the factors affecting the selection satisfaction of major of radiology students. After conducting a questionnaire survey on radiology students, we conducted t-test and multiple regression analysis. There was a significant difference between the preference and current factor among the selection of department. There were significant differences in clinical practice between practice environment, practice guidance, practice time and evaluation, satisfaction after practice, and employment. There were significant differences in curriculum framing, professor teaching and evaluation, support facilities, education system satisfaction, and curriculum satisfaction. As a result, it is necessary to develop system for increasing satisfaction with student's major selection and to improve the quality of education.

This study aimed to analyze the level of professors' understanding and perception of adaptive learning and proposed how college can implement successful adaptive learning in college classes. For research purposes, online survey was conducted by 162 professors of A university in capital region. As a result, professors seemed to feel pressure to provide students personalized feedback and gave concerned that students don't study enough in advance before participating in class. It was also found that professors realized that they have low level of understanding about adaptive learning, while they revealed intention to make use of adaptive learning in their class. They also answered that adaptive learning system is the most helpful support for encouraging professors to apply adaptive learning in real class. We proposed what is required to encourage professor to implement adaptive learning in their class.
