Humanity faces the 4th industrial revolution, many countries are providing systematic and continuous SW education to foster talent with AI capabilities. On the other hand, there are high concerns that the SW gap will widen and polarize as domestic reality does not provide systematic and continuous SW education to learners. Against this background, this study started to investigate the influence of learners' SW experience on SW education. As a result of the study targeting science and engineering students, the effect of SW experience on SW education was significant. With theses results, it is expected that various discussions will be actively conducted so that systematic and continuous SW education can be provided in elementary and secondary schools.

Recently, interest in Edu-Tech, which applies new technologies to the educational field, is growing. Edu-Tech is now being naturally used in schools, allowing both teachers and students to adapt to these changes. Particularly, there's significant attention on using Edu-Tech to bridge the educational gap through various teaching and learning strategies. This study focuses on the importance of self-directed task management by students for supplementary learning. It developed and utilized a math learning platform that enables teachers to easily provide and manage necessary tasks for students. Initially, the study developed "Sussam-MathTeacher" a problem-based learning application for middle school students, aimed at enhancing problem-solving abilities. This platform operates as a task management system, allowing teachers to assign or recommend problems to either the entire class or individual students. It aims to improve students' problem-solving abilities through a process that includes presenting necessary tasks, monitoring their own progress in solving problems, and self-assessing growth. Through this study, students demonstrated improved problem-solving skills by tackling tasks suited to their levels using "Sussam" highlighting the critical role of teachers in the digital educational environment.

최근 자연어처리 분야에서는 BERT, RoBERTa, 그리고 BART와 같은 사전 학습된 언어 모델 (Pre-trained Language Models, PLM) 기반 미세 조정 학습을 통하여 여러 하위 과업에서 좋은 성능을 거두고 있다. 이는 사전 학습된 언어 모델 및 데이터 집합의 크기, 그리고 모델 구성의 중요성을 보여주며 대규모 사전 학습된 언어 모델이 각광받는 계기가 되었다. 하지만, 거대한 모델의 크기로 인하여 실제 산업에서 쉽게 쓰이기 힘들다는 단점이 명백히 존재함에 따라 최근 매개변수 효율적인 미세 조정 및 Few-Shot 학습 연구가 많은 주목을 받고 있다. 본 논문은 Prompt tuning, Prefix tuning와 프롬프트 기반 미세 조정 (Prompt-based fine-tuning)을 결합한 Few-Shot 학습 연구를 제안한다. 제안한 방법은 미세 조정 ←→ 사전 학습 간의 지식 격차를 줄일 뿐만 아니라 기존의 일반적인 미세 조정 기반 Few-Shot 학습 성능보다 크게 향상됨을 보인다.

최근 e-러닝 산업 및 기술에서 큰 화두는 디지털 융합과 현상이라고 할 수 있으며, 이러한 융합화 시대를 향한 진화의 핵심적인 요구사항은 OSMU 이다. 현재까지 e-러닝 산업은 표준화 활동을 통해 디지털 융합화를 실현하고 있으며, 미국 ADL의 SCORM이 사실상의 표준으로 인식되고 있다. 하지만 기존 웹 기반의 e-러닝 환경은 학습을 할 때 컴퓨터에 의존함으로써 실질적인 디지털 격차를 극복하기에 한계가 있다. 이에 본 논문에서는 보다 실생활에 근접한 DiTV용 T-러닝 학습 환경에의 적용을 위하여 이미 작성된 SCORM 기반의 학습 콘텐츠 메타데이터를 DiTV용 TV-Anytime 메타데이터로 변환하여 상호운용성, 재사용성 및 고 이용성 등을 가능하게 하는 시스템의 설계를 제안하고자 한다. 이 시스템을 통하여 PC 에 익숙하지 못한 사람들을 DiTV 앞에서 더욱 편한 학습 기회를 제공할 수 있을 것이다.

Since 2005, Cyber home learning systems(CHLS) have been run with the purpose of clearing up the regional disparity and reducing the private education cost. At this point, it is necessary to have the analysis on the satisfaction and effectiveness awareness of the CHLS. The goal of this paper is to suggest an evaluation model for satisfaction and pedagogical effectiveness of CHLS and to support the management of satisfaction and effectiveness awareness of the CHLS for the low-income bracket children. Our major contributions can be summarized as follows: First, we present an evaluation model of satisfaction and effectiveness awareness of the CHLS for the low-income bracket children. Second, we survey the satisfaction, effectiveness awareness and improvement facts from the students who divided according to their sex, residence area and classes and compare with suggesting evaluation models. This paper is to find the measurement of the satisfaction and effectiveness awareness of the CHLS for the low-income bracket children. Furthermore, we can use this model as a material to balance the education opportunity, which is the purpose of CHLS, and abolish the education differentials.

본 논문에서는 IIoT 환경에서 중요한 비정상적 데이터 수집을 위한 노드 우선순위 선정 모델을 제안하였다. 제안하는 모델은 비정상적 데이터 수집과 다른 노드로 부터의 정상 데이터의 수집 격차를 적절히 조절하기 위하여 Fair and Delay-aware Cross-layer(FDRX) 기법과 데이터 Classification 기법을 이용, 데이터의 긴급성과 네트워크 환경을 분석하여 노드를 평가한다. 이를 통하여 IIoT 환경에서의 데이터 분석에 중요한 비정상적 데이터를 원활하게 수집하면서도 다른 노드와의 전송 격차를 줄일 수 있을 것으로 기대된다.

Recent information and technology is strongly targeted at the young generation, but little research has been undertaken on the older generation. The 55~79 age group was over 1,000,000 people in 2012. As a result, the problems of the information gap and of job creation for older people is becoming a critical social challenge. Because of this need, this research aims to suggest study method to reduce the information gap through informatization education for people of advanced age. Through this, older people can be mentors and play a key role in society as well as contributing to reduce social conflicts. This research is undertaken based on elderly IT volunteers, and is expected to solve the information gap problem through advanced age IT education and job creation with talent donation.

Although COVID-19 has transitioned to a level 4 infectious disease in 2023 and has entered a stable trend, in special education settings, the importance of supporting the academic and social development gaps of students with disabilities caused by non-face-to-face learning situations such as remote classes during the COVID-19 period is emerging. there is. Accordingly, in this study, in order to identify and support the educational status and academic deficits of students with disabilities after COVID-19, we conducted a survey targeting 2,214 special education teachers in 17 cities and analyzed the results. As a result of the study, due to COVID-19, the developmental delay and educational gap in students with disabilities in terms of academics, emotions, and behavior deepened, and there was a high demand for manpower support, psychological counseling, and medical support for emotional behavior as a way to support this. Based on the results of this study, follow-up results were proposed.

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.
