비디오 강의를 활용한 온라인 학습은 교육 효과를 높이는 무한한 가능성을 가지고 있지만 온라인에서 학습자 주도로 이루어지기 때문에 학습 동기를 높이고 온라인 강의에 집중시킬 수 있는 도구의 개발이 필요하다. 또한 교수자는 온라인 환경 안에서 학습자가 실제로 학습을 수행했는지에 대한 여부를 쉽게 파악할 수 있는 도구의 개발이 필요하다. 본 논문은 학습자와 교수자의 요구를 만족 시킬 수 있는 단어게임 기반의 온라인 비디오 학습 자동 판단 시스템을 개발하였고, 시스템 검증을 위해 343명의 학습자를 대상으로 사용자 만족도 설문조사를 수행하였다. 설문 결과, 83%의 시스템 용이성, 73%의 시스템 만족도로 긍정적인 결과를 보였다.

The purpose of this study was to make a survey of the operation of childcare facilities in rural regions through in-depth interviews with 5 facility principals. Owing to regional disadvantages, rural childcare facilities have many problems as follows: uneven distribution of facilities, shortage of teachers, financial difficulties, unsuitable programs for rural regions, insufficient reeducation of principals and teachers, and poor operations and accessibility for handicapped or very young children. The principals proposed that many conditions might be made better as follows: evenly distributing facilities in step with needs and supply, raising the salary of teachers of rural facilities, supporting the facilities themselves side by side with supporting children, improving 'childcare fee supporting system' of the Ministry of Agriculture and Forestry, developing and spreading programs suitable for rural regions, and promoting the reeducation of principals and teachers through online programs.

최근 초고속 인터넷망의 발전으로 실시간으로 화상 교육 시스템 구축이 가능하게 되었다. 그러나 기존의 화상교육 시스템은 단순히 사용자의 얼굴과 음성만을 전달하기 때문에 교육적인 측면에서 실감나는 교육 시스템으로는 볼 수 없다. 본 연구에서는 웹캠으로 촬영된 영상을 3D 가상공간에 적용시켜 사용자가 교육 현장에서 교육활동이 이루어지는 것과 같은 실감나는 교육 서비스를 제공할 뿐만 아니라 교육에 필요한 문서, 음성, 자료 공유를 실시간으로 할 수 있는 시스템을 개발하였다.

Recent advances in Internet-of-Things and wearable computing have established computationally sufficient infrastructure to remove the barriers of physical locations. The recent COVID-19 pandemic has accelerated the use of remote collaboration, work-from-home, teleconferencing, online education, digital twin, and metaverse enriched with various configurations of augmented reality, virtual reality, mixed reality, and extended reality. Beyond specialized niche wearable applications in the medical and entertainment domains, we aim to identify the underlying characteristics of smartglass-enabled killer applications for everyday use. In this paper, we analyze intermediary roles in remote collaboration consisting of authoritative supervisors, synergetic collaborators, and speculative explorers. We also propose technical components for smartglass-assisted interactive remote collaboration composed of personal tracking, teleconference, and interaction components. More specifically, the application tasks of each intermediary role and objectives of three functional components are defined and elaborated.

This paper presents calibration of flush air data sensing systems during ascent period of a satellite launch vehicle. Aerodynamic results are numerically computed by solving three-dimensional time dependent compressible Euler equations over a payload shroud of a satellite launch vehicle. The flush air data system consists of four pressure ports flushed on a blunt-cone section of the payload shroud and connected to on board differential pressure transducers. The inverse algorithm uses calibration charts which are based on computed and measured data. A controlled random search method coupled with neural network technique is employed to estimate pitch and yaw angles from measured transient differential pressure history. The algorithm predicts the flow direction stepwise with the function of flight Mach numbers and can be termed as an online method. Flow direction of the launch vehicle is compared with the reconstructed trajectory data. The estimated values of the flow direction are in good agreement with them.

Universities that offer architectural engineering programs in Korea are making efforts to introduce innovation teaching methods to cultivate teamwork, creativity, flexibility of thought and practical skills needed for the Fourth Industrial Revolution. However, there is a lack of specific measures to support them. In this regard, this study investigated a method of application development for building construction courses applied with the innovation teaching methods. It mainly focused on 'improvement directions for existing learning management systems' and 'online learning support plans using the innovation teaching method' as research contents. It is expected that these improvement directions can be applied to the field of education through the development of mobile and web-based applications. In the follow-up research, the development of specific software for field application will be carried out.

The purpose of this study is to explore adolescent depression, increase understanding of social problems, and develop prevention and intervention strategies. As a research method, social big data was used to collect information related to 'youth depression', and related factors were identified through data mining and analysis of related rules. We used 'Sometrend Biz Tool' to collect and clean data from the web and then analyzed data in various languages. The study found that online articles about depression decreased during the school holidays (January to March), then increased from March to the end of June, and then decreased again from July. Therefore, it is important to establish a government-wide depression management monitoring system that can detect risk signs of adolescent depression in real time. In addition, regular stress relief and mental health education are needed during the semester, and measures must be prepared to deal with at-risk youth who share their depressed feelings in cyberspace. Results from these studies can be expected to provide important information in investigating and preventing youth depression and to contribute to policy development and intervention.

온라인 교육의 보급이 증가함에 따라 온라인 학습자의 중도이탈율을 줄이기 위한 효과적인 전략이 필요해 졌다. 본 논문은 인공지능 기술을 온라인 학습 분야에 적용하여 온라인 학습 중도 이탈 문제를 해결하고자 한다. 특히 온라인 교육기관에서 중도이탈예측 시스템을 이미 운영 중인 온라인교육시스템(LMS)을 새롭게 구축하거나 크게 변경하지 않고도 개발 또는 도입이 가능한 방안을 제시한다. 운영 중인 온라인교육시스템(LMS)에 저장되고 있는 온라인 학습자들의 학습자정보 및 학습 이력 데이터를 활용하여 중도 이탈 위험이 있는 학생을 식별하고 맞춤형 관리가 가능하도록 온라인 교육 중도 이탈예측 시스템 개발하고 LMS와 연동하여 서비스는 방법을 제안한다. 이를 통해 온라인교육기관에서는 중도이탈이 있는 학생을 효과적으로 관리함으로써 온라인 교육의 질을 향상시킬 수 있고, 더 많은 수의 온라인 학습자가 성공적으로 과정을 이수할 수 있도록 하는 데 기여할 것이다.

This paper presents an internet-based self-learning educational system which can be enhancing efficiency in the learning process of Java language. The proposed self-learning educational system is called Java Web Player(JWP), which is a Java application program and is executable through Java Web Start technologies. In this paper, three important sequential learning processes : concept learning process, programming practice process and assessment process are integrated in the proposed JWP using Java Web Start technologies. This JWP enables the learners to achieve efficient and interesting self-learning since the learning process is designed to enhance the multimedia capabilities on the basis of educational technologies. Also, online voice presentation and its related texts together with moving images are synchronized for efficient language learning process. Furthermore, a simple/useful compiler is included in the JWP for providing language practice environment such as coding, editing, executing and debugging Java source files. Finally repeated practice can make the learners to understand easily the key concepts of Java language. Simple multiple choices are given suddenly to the learners while they are studying through the JWP and the test results are displayed on the message box.

Web Based Instruction has its theoretical background in constructivism paradigm of education. According to social changes called information era and thanks to the sophisticated internet mechanism the constructivism in education has been dominant paradigm. In this paradigm information and knowledge are not merely given by a instructor facing the loaners. This system of instruction has n almost every field of discipline introduced. This article aims to examine how far WBI and constructivism are applicable for design education. Richard Branchia predicted that the learner oriented instruction method would become the dominant education system. He stressed an interactivity of the teacher and students. Upon this can the applicability of WBI for design education be affirmed. Furthermore, there is a dozen of successful cases like www.cyberartcenter.com) (www.digitalyeil.co.kr)', http://www.schooleweb.co.kr/, htp://www.startstudy.co.kr/among many others. This article suggests several ways to solve the problems web based design education faces, including the lesson should inevitably combine the outline and of online study.
