So far, there were a few web-based distance English learning systems for children. The existing systems for children have not appropriately reflected their learning characteristics and interests, since most of those systems regards mainly adults as targets. This thesis is aimed at proposing more effective educational service modules of web-based real-time system in order to encourage children's interests as much as possible in learning English. The web-based real-time distance learning system is a model based on the survey over the current use and satisfaction status of elementary school students who have actually used those kinds of systems. With the great expectation of more effective way of learning English, it also focuses on attracting parents to participate the learning process by providing a service to look over, in real-time, what their children do through the internet-based English learning system.

Due to the characteristic that early childhood education is a process of nurturing children's senses by a leader rather than the transfer of knowledge, even in the era of with Corona, early childhood distance education is not one-to-one non-face-to-face education, but rather through distributed materials such as early childhood education packages or media such as TV. Distance education was conducted in a self-care method. Through a review of prior research and intensive parent interviews, the researcher identified the requirements for distance education, such as the expansion and accessibility of educational contents, understanding of basic knowledge of early childhood distance education, and the need to increase children's social skills through real-time distance education. It was identified that the current distance education-related solutions are not suitable for early childhood education. Accordingly, the researcher presents the basic direction (VERI) of the early childhood distance education solution of diversity, ease, real-time communication, and integration, and provides a Web/App platform that allows children, parents, and teachers to share content and communicate in real time and in non-real time. The development of a solution was proposed. This distance education solution is expected to effectively support early childhood distance education in the era of With Corona as infants, parents, and teachers communicate and share the current situation, which is only presenting guidelines and materials.

최근 모바일 기기의 사용이 급증하면서 모바일 단말기를 기반으로 하는 모바일 원격교육 시스템이 연구되고 있다. 우리는 태블릿 기반의 실시간 원격교욱 시스템을 개발한 경험이 있다. 이 시스템은 학생이 실시간으로 강사의 강의를 보고 들으며 슬라이드 및 애노테이션을 볼 수 있게 해준다. 또한 이 시스템은 학생이 채팅기능을 통해 강사에게 질문을 허용함으로써 강사 학생간의 상호작용을 지원한다. 그러나 이 시스템은 학생들이 채팅창에 가상키보드를 통해서만 입력하는 것을 허용하였기 때문에 입력 속도가 떨어지고 편의성이 저하되는 문제점이 있었다. 따라서 본 연구에서는 채팅기능의 Speech to Text 기능을 추가하여 학생들의 음성입력을 지원하도록 시스템의 강사 학생간의 상호작용 부분을 개선하였다. 그리고 강사 학생간의 상호작용에 대한 사용자 평가를 통하여 개선된 시스템이 기존의 시스템에 비하여 입력 속도 및 편의성 면에서 어느 정도 개선되었음을 알 수 있었다.

Current distance loaming or cyber teaming offers learner the same level of contents regardless of learner's degree of understanding and the progress of learning also may be controlled by learner freely. In this paper we improve the several problems of distance teaming and cyber learning, and propose new real-time intelligent distance learning. First, we provide learners with the contents of lectures that are appropriate to learner's level. After that we analyze md judge the degree of understanding of learners, the results are informed to instructors for further uses. Due to the diagnosis result instructors know the frail part of learners and let them understand that, and highlight the efficiency of learning. Session with instructor and learner is performed with multimedia communication using Internet, and all the educational materials are shared by instructor and learner at the same time.

For effective remote education using multimedia, it is necessary to develop efficient management techniques of video information. This requires real-time processing of video information which should be managed and retrieved in a compressed forms. The main technology of compressing video is currently MPEG-2. This implies that it is very important to manage and retrieve video compressed in MPEG-2, and then to process the video in real-time for the remote education environment using multimedia. This paper is to develop the management system of video information which is one of the most critical requirements in remote education systems for managing and retrieving MPEG-2 video.

기존 원격교육 시스템들은 주로 UNIX 기반이며 원격학습을 위한 모든 기능을 서버에서 처리하게 하였다. 따라서 대용량의 시스템이 필요하였고, 여러 강좌를 동시에 실시간으로 강의하는데는 여러가지 제한이 있었다. 본 연구에서 제안한 원격학습 시스템은 사양이 높아진 클라이언트 PC를 최대한 이용하여 서버 시스템의 크기를 줄였다. 원격강의를 할 때 강의의 개설은 메인 서버에서 이루어지게 하고, 실제 강의는 강좌를 개설한 교수 PC로 서버 기능을 전환하여 실시간 강의를 진행할 수 있도록 하였다. 이러한 방법은 서버에 집중되는 부하를 줄이고 실시간으로 동시에 여러 과목의 강의나 다양한 원격토론 학습이 가능하다. 또한, 원활한 강의 및 토론을 위해서 클라이언트 프로그램에 강의에 필요한 기능들을 최대한 포함시켜서 네트워크간의 데이터 이동을 최소화하였다.

Most existing mobile distance learning systems are asynchronous ones that allow students to download lecture video and presentation material. However, there are a few synchronous real-time mobile distance learning systems that support slide, annotation, feedback from student, and lecture video and audio at the same time. These live mobile distance learning systems have an advantage of supporting real-time interaction between students and a lecturer thereby making students understand the lecture better. But, they also have a disadvantage in the sense that they don't allow students to experience the past lecture. This problem can be solved by recording and replaying lecture session. So far, there are few mobile distance learning systems that support session recording and replay. This paper presents a synchronous mobile distance learning system that supports video and audio, slide with annotation, and real-time feedback from students, as well as session recording and replay, which is not supported by the existing mobile distance learning systems. The evaluation of the system among students shows that 61.3% of them were satisfied while 3.2% weren't.

Purpose: Due to the coronavirus infection-19 (COVID) pendemics, all educational institutions were required to provide full non-face-to-face real-time education, and fire officials were required to provide fire-fighting education by applying non-face-to-face education. In this difficult situation, the National Fire Service Academy tries to find the direction of the non-face-to-face real-time education and suggest ways to improve it through a survey of the status of non-face-to-face real-time education conducted by the NFSA to fire officials. Method: A survey was conducted on fire officials under the theme of "Consciousness Survey for Improving the Quality and Specialization of Non-face-to-face Real-Time Remote Education" and an in-depth analysis was conducted based on the results. Result & Conclusion: First, professors or educational operators shall actively utilize remote education programs suitable for educational characteristics by utilizing various programs. Second, a dedicated notebook for non-face-to-face training should be provided to provide an educational environment where all learners can participate in the training without difficulty. Third, in the case of education and training that requires the use of equipment due to the nature of fire officials' education and training, it is necessary to consider it as a non-face-to-face training place by arranging educational equipment at each fire station. Fourth, it is hard to expect a satisfactory educational effect to cope with practical education with theoretical education. Therefore, facilities and programs that enable non-face-to-face real-time hands-on training should be developed. It is worth considering the proper combination of face-to-face education while maintaining the social distance as much as possible until such non-face-to-face training is possible. Fifth, non-face-to-face education is considered to have high eye fatigue due to the light and electromagnetic waves of the computer screen, and as time goes by, the concentration level decreases. Therefore, it is necessary to form an education time to reduce the eye fatigue of learners and increase concentration through proper class and rest time. Finally, professors should operate a learner participation-oriented education that allows professors and learners to interact rather than one-sided knowledge transfer education. In addition, technical problems of non-face-to-face remote education should be thoroughly prepared through preliminary system checks to ensure that education is not disrupted.

본 논문에서는 실시간 원격 수업(Real-Time Distance Education) 환경 하에서 학생들의 수업 집중 및 효율적인 교수를 위한 버즈학습(Buzz Learning)의 필요성을 제안한다. 이 학습법은 실시간 원격 수업에서 일어날 수 있는 집중력 저하 및 수업참가율 저조를 최소화하고, 학습자 간의 협동 및 상호작용을 향상시킨다. 또한 버즈법에 의한 그룹 편성 및 학습형태는 각 그룹에서 토의한 결과를 다시 전체가 모여 토의함으로써 소집단의 토의결과를 종합 정리하고 결론을 도출해 내는 집단 토의 형태를 띤다. 토의학습은 흔히 몇몇 학생의 경우 토의에 참가하지 않거나 또는 한 명이 독무대화하는 경향이 있는데 여기서는 그룹 전원이 토론에 적극 참여할 수 있게 한다. 본 논문에서는 실시간 원격 수업을 통하여 이뤄지는 실제 강의에 적용된 버즈 학습이 학생들의 수업참여도 및 학습 향상 면에서 우수함을 보여준다.
