  • With the rapid development of domestic and international over-the-top markets, a large amount of video content is being created. As the volume of video content increases, consumers tend to increasingly check data concerning the videos before watching them. To address this demand, video summaries in the form of plot descriptions, thumbnails, posters, and other formats are provided to consumers. This study proposes an approach that automatically generates posters to effectively convey video content while reducing the cost of video summarization. In the automatic generation of posters, face recognition and clustering are used to gather and classify character data, and keyframes from the video are extracted to learn the overall atmosphere of the video. This study used the facial data of the characters and keyframes as training data and employed technologies such as DreamBooth, a text-to-image generation model, to automatically generate video posters. This process significantly reduces the time and cost of video-poster production.

  • Trajectory prediction is an essential element for driving autonomous vehicles, and various trajectory prediction models have emerged with the development of deep learning technology. Convolutional neural network (CNN) is the most commonly used neural network architecture for extracting the features of visual images, and the latest models exhibit high performances. This study was conducted to identify an efficient CNN backbone model among the components of deep learning models for trajectory prediction. We changed the existing CNN backbone network of multiple-trajectory prediction models used as feature extractors to various state-of-the-art CNN models. The experiment was conducted using nuScenes, which is a dataset used for the development of autonomous vehicles. The results of each model were compared using frequently used evaluation metrics for trajectory prediction. Analyzing the impact of the backbone can improve the performance of the trajectory prediction task. Investigating the influence of the backbone on multiple deep learning models can be a future challenge.

  • 컴퓨터와 인터넷의 발달은 전통적인 교실교육을 벗어나 시공간을 초월한 사이버 교육을 가능하게 하였다. 그 결과 웹기반 학습환경에서는 학습자의 자기주도적인 학습이 가능하게 되었다. 효율적인 자기주도적 학습환경을 위해서는 학습시 어려움을 느끼는 학습자에게 스캐폴딩(scaffolding)이라는 적절한 도움과 지원을 제공해야 한다. 본 논문에서는 공업계고등학교 정보기술기초교과 컴퓨터의 원리 단원을 선정하여 학습자에게 적절한 스캐폴딩을 제공할 수 있는 웹 콘텐츠를 설계 및 구현한다.

  • Since 'teaching coding' or 'programming' classes for computational thinking (CT) education in K-12 are renowned around the world, a pre-service teachers' readiness for integrating CT into their teaching subjects is important due to the fact that CT is considered to be another 'R' from algoRitm for 21st century literacy, in addition to the traditional 3R (Reading, Writhing, and Arithmetic) [2] and CT roles to other disciplines. With this rationale, we designed a guided instruction based CT course for pre-service teachers. We show the effectiveness of the program with respect to the teachers' attitude toward combining CT into their teaching subjects, and mindset changes of learning computing connected with the career development of the teacher themselves. The research focused on the instructional methodology of teaching programing for non-Computer Science Education (CSE) majors who are not familiar with computer science for alleviating the cognitive load of first exposure to programming course under the CT concepts.

  • In this paper, we propose a Science subject program based on programming learning to improve computational thinking ability in middle school. As the necessity of software education rises recently, the subject of information was designated as the mandatory subject in elementary, middle and high schools. In order to cultivate the ability that enables the leaners to search the knowledge in need by themselves and raise troubleshooting method, not the existing indoctrination, his thesis was willing to improve Computational Thinking ability and improve the ability of considering and thinking the matters by using scratch language. For that, this thesis developed and suggested science subject program that utilizes the programming learning.

  • 2022 개정 교육과정에서 정보과 융합 선택 과목인 소프트웨어와 생활이 신설되었다. 교과의 '가치를 창출하는 소프트웨어' 단원은 소프트웨어 스타트업의 프로젝트 수행 과정에 대한 이해를 바탕으로 소프트웨어 구현능력을 성취 기준으로 제시하고 있다. 그러나, 고등학생 대상 소프트웨어 스타트업 교육 방법에 대한 국내연구가 거의 없어 교과용 도서 개발에 어려움을 주고 있다. 이에 본 연구에서는 2022 개정 교육과정과 소프트웨어 스타트업 교육에 대한 국외 연구를 분석하여 고등학생 대상 소프트웨어 스타트업 교육의 방향을 제시하였다. 본 연구에서 제시된 내용은 소프트웨어와 생활 교과용 도서를 개발하는 데 도움이 될 것으로 기대된다.
