Due to the development of online media platforms and the COVID-19 incident, the mass production and consumption of digital video content are rapidly increasing. In order to select digital video content, users grasp it in a short time through thumbnails and teaser videos, and select and watch digital video content that suits them. It is very inconvenient to check all digital video contents produced around the world one by one and manually edit teaser videos for users to choose from. In this paper, keyframes are extracted based on YCbCr color models to automatically generate teaser videos, and keyframes extracted through clustering are optimized. Finally, we present a method of producing a teaser video to help users check digital video content by connecting the finally extracted keyframes.

프로그래밍 능력은 21세기 정보화 사회를 살아가는데 있어 인간이 컴퓨터를 활용하여 다양한 문제를 해결할 수 있도록 도움을 준다. 효과적인 프로그래밍 교육이 이루어지기 위해서는 학습자들에게 순차적 수행, 조건적 수행, 반복적 수행과 같은 기본적인 프로그래밍 개념을 습득하도록 할 필요가 있다. 따라서 본 연구는 스도쿠 인공지능 프로그래밍 교육에서 프로그래밍의 기본 개념을 바탕으로 알고리즘을 설계하는 방법을 학습시키는 방안을 모색하기 위한 목적이 있다. 연구의 목적을 달성하기 위해 중학생 10명을 대상으로 실험 연구를 진행하였다. 연구 결과, 학습자는 연구자가 제안한 활동지가 알고리즘 설계 학습에 도움이 된 것으로 인식한 것을 확인할 수 있었다. 본 연구는 프로그래밍 교육에서 초보 학습자가 이해하기 어려워하는 프로그래밍 개념을 학습하는데 도움이 되는 학습 방법을 제시하였다는데 의의가 있다.

Researches on prodigies and education for those have recently been progressing in many fields. Education for the gifted, which was basically on Math and Science on the start, now includes Intelligence, Invention, Cultural Sciences, Art, and so on. With the progression towards extremely developed information society, interests in and importance on the courses for the talented get more and more focused. The problem is, however, choosing the gifted and educating them is not an easy matter, since the history of Intelligence Technology is relatively short and it is hard to identify prodigies and categorize what kinds of courses they need. Also, from 2010 "Science Education Institute for the Gifted" freshmen draft, paper-based admission test has been discarded and teacher-recommendation through long-term observation introduced. Therefore needs have been increasing for quality selection methods including observation records, recommendation letters, and portfolios. Reformation on teaching and creative selection methods has been accentuated because of lack of academic base for selecting candidates for education for the gifted. Because of all those mentioned above, reliances for the selection processes during the last three years and the one in 2010, observation records, recommendations and portfolios included, have been analyzed and evaluated. Several factors which can be used instead of paper-based tests were coordinated. Based on it, it was highly possible and has been successful to draft all the applicants in cognitive, sentimental, and creative fields.

The current Sudanese preschool system depends on limited methods of education, children's education needs to be equipped to keep pace with technological development, also, the large gap that exists between the families and the Kindergartens, where many parents have no idea on how their child progresses in the KG context. The aim of this research is to integrate ICT in the preschool education to enhance and improve the preschool education, by building an Integrated Educational Application (Computerized Application for Preschool Education CAPE) which will help to improve the learning outcomes. The researchers used the Experimental Research Methodology, the characteristic of CAPE application is; suitable for children's age, the application style is more attractive to the children and contains a different way to help children get learning. Alawaeel and the Smart Child Kindergartens in Republic of Sudan were selected as a sample of the study, with sample size specifically, 50 children's. Also, the Central Bank of Sudan Kindergarten was selected as one of the institutional Kindergartens for easy communication with parents of children with a sample size 21 children. The study found that; using CAPE application in KG enables children to increase general learning effects and developing child's cognitive skills. Also, the children who were allowed to use CAPE by their parents are performed better in the overall evaluation of KG lessons. Also, using the CAPE in the Pre-School education helps the parents following their children's progress better and more reliable. The researcher recommends that to apply the computerized application and includes the second level. Also, converting the computerized program into an application to be used by children by their self, without the intervention of parents.

Given the background of so-called 'the 4th industrial revolution', universities practice computing education for non-majors to equip them with computational thinking(CT). Universities apply different courses but researches analyzing effectiveness of the courses based on CT are limited. This research is conducted to understand a computing course for non-majors is effective in terms of CT. A CT based evaluation framework is designed referring to AP Computer Science Principles. Questionnaires are developed based on the framework and applied to the course participants. As results, students' post scores are significantly higher than pre scores. In addition, there are significant differences in pre-test scores by major category while there is no difference in post-test. Humanity & social science group showed the largest difference between pre and post results with science & engineering and computer in order. In sum, it is found that this course is effective to facilitate students abilities in terms of CT, particularly for the non-computer majors.

The evaluation of students' computational thinking begins with the evaluation of knowledge about the concepts and principles of computing. In this study, we analyzed the differences in teachers' perceptions depending on the description method of the bebras challenge questions to evaluate computer science knowledge. First, we classified the questions into two types depending on whether computer science terms were included or not. Also we made a computational thinking questionnaire with two types of questions and surveyed 72 major teachers. As a result, teachers expressed the opinion that the evaluation questions that revealed computer science terms were appropriate as evaluation questions for information subjects. They also perceived it as more helpful in assessing computational thinking and coding skills. Through the results of this study, we suggested that the way the questions are worded is important in the process of assessing students' understanding of computer science concepts and computational thinking skills.

All possible efforts have been done to adapt to the information-oriented society throughout the whole area of education. Especially, it is strongly demanded that teachers should effectively apply information communication and disposal to all the educational activities of instruction-learning, students management, school affairs, and administrative affairs. In this thesis, we chose as educational contents the information technology which is necessary in an educational site to increase the capability of applying information of teachers and developed remote training materials. In addition, we developed measurement instruments to evaluate the capability of applying information of teachers and gave grades to them. Grading System of the Capability of Applying Information of Teachers will be a standard of the capability of applying information.

정보 사회는 컴퓨터 과학이 실생활 뿐 아니라 모든 학문 분야의 기반이 되는 사회이다. 자원이 부족한 우리나라는 핵심 학문 분야의 인재 양성이 국가 경쟁력을 강화할 수 있는 원동력이 되기 때문에 컴퓨터 과학 분야의 인재를 양성하기 위한 정보 교육의 중요성이 더욱 커지고 있다. 이러한 일환으로 2015 개정 교육과정에서는 정보 교육을 필수화하였고 어떻게 가르칠 것인가에 대한 많은 연구가 진행되고 있다. 교과서는 학습자의 가장 기본적인 학습 도구가 되는 것으로 어떤 지식을 어떻게 가르칠 것인가를 포함하고 있기 때문에 그 구성은 매우 중요하다. 따라서 본 연구에서는 컴퓨터 과학을 인력 양성을 위한 중요한 학문으로 인식하고 정보 교육의 활성화를 추진하여 실천하고 있는 영국의 교과서를 분석하고 우리나라에 주는 시사점을 제시하였다.
