인공위성을 통해 취득된 데이터들은 지상국의 수신처리시스템을 거쳐 표준영상으로 생산되며, 생산된 영상으로부터 사용자에게 의미 있고, 가치 있는 정보를 이끌어 내는 판독의 단계를 수행하게 된다. 본 연구에서는 원격탐사의 전반적인 이해를 돕기 위한 교육적 모델로서 캔샛 프로그램을 도입하였다. 캔샛 프로그램은 스탠포드대 로버트 트윙 교수의 제안으로 학생들에게 한 학기의 짧은 시간에 실제 인공위성의 설계, 해석, 제작, 조립, 시험, 발사, 운용 등 전반적인 시스템의 이해를 도모하기 위한 1Kg 이하의 캔 크기의 초소형 위성을 개발하는 교육 프로그램이다. 본 연구는 한국과학영재학교 R&E 프로그램의 지원으로 시작하였으며, 실제 초소형 위성 캔샛('KSAsat'으로 명명)을 직접 설계, 제작, 조립하고 최종적으로 발사 운용 시험을 수행하였다. 주 탑재체로 일반 상용 디지털 카메라를 장착하였으며, GPS, 광센서, 3 축 가속도계, 온도센서, 압력센서를 탑재하였다. 비행시험을 통해 성공적으로 영상을 취득하고, 각종 센서로부터의 데이터를 지상국으로 전송 받았다. 지상국을 통해 처리 되어진 데이터로부터 의미 있는 정보를 추출하는 판단의 단계를 거쳐 원격탐사의 전반적인 교육을 성공적으로 수행할 수 있었다. 본 논문에서 캔샛 프로그램이 원격탐사 교육에도 충분히 활용될 수 있음을 보였다.

This study it to verify the validity of Korean version of DELES (distance education learning environment survey) and analyze its relationship with learning achievement and distance education satisfaction. The target population of this study is students of K cyber university and a total of 254 cases are used for the analysis. Exploratory and confirmatory factor analysis is applied to verify 6 factors of DELES and structural equation analysis is applied to examine the relationship between distance education learning environment and learning achievement and distance education satisfaction. The study result shows that DELES is composed of six factors such as instructor support, student interaction & collaboration, personal relevance, authentic learning, active learning and student autonomy and its model fits are appropriate. The result of structural equation analysis shows distance education learning environment significantly influences distance education satisfaction directly as well as indirectly mediated by learning achievement. Learning achievement also significantly influences distance education satisfaction. Conclusions and implications are followed.

The development of distant education on the internet has undergone a great change. However, many of the educational ways force to students to acquire the technical skills by repeatedly practising the contents. These learning styles have certain advantages, for example, providing feedback without delay and constant learning, but they also have disadvantages. For instance, they reduce the motivation and interest level of the students. And if the students don't participate in class, they simply will not improve in their ability. This study provides a solution which will has an influence on the other classes. We can utilize self-learning, interactive and leveled studying with animation and teaching aids.

By 'National GIS Plan', various strategies and programs have been carried out for the professional training in the fields of geospatial information. The e-learning can make it possible to develop and manage the adaptable curriculums, to maximize the effect of the practical exercises, and to establish the cooperative systems with the industries. In this study, curriculums of the geospatial fields were developed and suggested for the cyber universities. These curriculums were divided into three stages, fundamentals, applications, and advances, and into three tracks, system development and construction, mapping and geospatial data construction, and practice and application, based on the current demands in geospatial industries. Owing to be the modularized structure, proposed curriculums would be easily adapted and updated to the change of the new demands.

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.

의사결정자 지원은 문제 인식, 대안 생성, 최적안 선정 등 협의의 의사결정 지원시스템 (Decision Support System, DSS) 뿐 아니라 의사결정자의 일상업무지원과 의사결정 능력 향상을 위한 교육을 포함한다. 본 논문의 목적은 의사결정자를 지워하기 위한 일종의 광의의 의사결정 지원 시스템인 의사결정자 지원시스템(Decision Maker Support System, DMSS)에 대한 개념적 틀을 제시하는 것이다. DMSS는 전통적인 의사 결정 지원시스템, 업무처리 시스템, 가상교육 시스템 및 이들을 통합 관리하여 특정 의사결정자의 요구에 맞게 구성해 주는 DMSS 관리자를 핵심 요소로 하며 원격의 의사결정자 존재를 생각하여 사용자 인터페이스는 웹 기반을 고려하였다. 특히 DMSS의 하위 시스템의 지식을 통합하기 위해 일원화된 지식베이스를 설계하였다. 그리고 DMSS의 가능성을 보이기 위해 가상 시나리오를 통해 설명하였다.

Based on recent fast development of computer and telecommunication technologies, the Distance Education System(DES) was introduced and utilized widely in the area of education. For an immediate and fluent communication between the teacher and the student under DES, the chatting subsystem was effectively used. However, the current chatting systems are not able to receive and transmit the mathematical symbols despite their indispensability in the process of problem and solution setting under remote mathematical education. In this study, thus, Equation Chatting System that can receive and send the mathematical symbols under the graphical user interface was designed and implemented.

Online education is a new domain of learning that combines distance learning with the practice of face-to-face instruction utilizing computer-mediated communication. As technology continues to develop and the needs of teachers require better access to higher learning, online graduate degree programs can be a valid alternative. Some institutions in the United States have already offered graduate degrees in music education through the online distance learning. In this study, 8 accredited online graduate degree programs in music education were identified in terms of curriculum requirement, program requirement, and admission requirement. Online programs offer considerable benefits of convenience, while their drawbacks relates to the quality of learning, feelings of weaker interpersonal interaction. More researches need in order for online music programmers to achieve higher standards of instruction and to inform other disciplines in the fields of arts education and the performing arts.
