Cyber learning goes up in the quantity of educational contents as informational technology develops in Korea. However some research for the structure of the contents has not been tried to examine its quality. Therefore this research analyzed the most popular cyber learning contents in Korea. They were characterized as "presentational contents". The main research methods are survey and execution of the presentational contents. For the survey, 100 trainee teachers were interviewed. The result of survey is that presentational contents are close to both the tutorial contents type and drill and practice type. On the other hand it is revealed that the response for simulation and game contents type is very rare. The result of the execution for presentation contents recorded high level for frequency of presentation and motivation. To solve these problems, the approach for developing presentational contents should select an appropriate curriculum for cyber learning system and incorporate effective teaching presentation with technology.

The Air and Correspondence High School (ACHS) has played a key role as an organization of lifelong learning since 1974. However, extra-curriculum in ACHS has not been operated successfully due to lacks of educational supports and on-line contents. So we surveyed demands of the ACHS teachers and students for successful operation of extra-curriculum, found four subjects that students preferred in the developing activity area which is one of extra-curricular activities, and experimentally developed four on-line contents for extra-curriculum. And we also applied the developed on-line contents to the students of Chongju H.S. After the application, another survey and interview were carried out to measure learner's satisfaction, find out problems of learning with on-line contents and suggest the ways of improving extra-curriculum learning system.

In the educational environment of the post-COVID-19 era, metaverse learning, which can improve the disadvantages of online learning and improve learning outcomes, is attracting attention. Metaverse is expected to play an important role as a learning experience platform (LXP) that can provide immersion and experience for learners. In order to successfully introduce and utilize metaverse learning that utilizes the metaverse platform, teachers' knowledge of metaverse-related technologies and pedagogical convergence is important. So far, teacher knowledge for educational use of the metaverse has not been explored. In this regard, this study explored the TPACK (Technological, Pedagogical And Content Knowledge) framework as a teacher's knowledge system for metaverse learning. Based on this, this study designed the class contents of metaverse learning. The results of this study are expected to diffuse the importance of TPACK required for metaverse learning and contribute to the development of teachers' competence.

Many e-Learning companies are incorporated for the last five years, but most of them are failed or merged by the other company. The main reasons are the absence of competitive strategies and recognition of critical success factors. There are many researches on the critical success factors of Information System (IS) and Electronic Commerce (EC) . We derived e-Learning success factors from the previous IS and EC researches. We classified the success factors into five dimensions, (1) contents management, (2) learner management, (3) business strategy, (4) organizational support and ability, (5) learning management system (LMS), and each dimension has 9 or more success factors measurement items. We surveyed the perceived importance of the success factors from the manager of South Korea e-Learning firms. The paper categorized the items into two or more factors for each dimension by the exploratory factor analysis. Finally, we conducted one-way ANOVA for each success factors by the business model. As a result, there is different importance level for each success factors by the business model. We concluded that each e-Learning company needs different strategies to their business model.

Inter-Korean Economic Cooperation needs to a different strategy for developing synergy effects, suggesting they should be selected for role to the unification Korea. In the this paper, Three policy-strategies is suggested as follows. Firstly, Economic Cooperation Driving Committee of Inter-Korean Digital Cultural Content is necessary the recovering of cultual consubstantiality and the operating of business partnership in the divided peninsular. Secondly, To cultural contents cooperation between South-North Korea. the exchange of learning and information must be activated constantly. as the cultural contents is creative industrial, it needs for imagination and creative of human and understanding of a fine arts, a traditional arts. Thirdly, A policy and system is inevitable to construction of Inter Korean Cooperation Digital Contents. South-North Korea, including a North Korea having a excellent cultural heritage, must jointly recovery for cultural contents. Under social-economic system, a consumers of digital contents pay to the format creator many royalty. Therefore, We must prepare to roll out a series of new creative contents, and have competitive advantages in the global market.

In this paper, we perform Single Image Super Resolution(SISR) for acquired images of EOTS or IRST from naval combat system. In order to conduct super resolution, we use Generative Adversarial Networks(GANs), which consists of a generative model to create a super-resolution image from the given low-resolution image and a discriminative model to determine whether the generated super-resolution image is qualified as a high-resolution image by adjusting various learning parameters. The learning parameters consist of a crop size of input image, the depth of sub-pixel layer, and the types of training images. Regarding evaluation method, we apply not only general image quality metrics, but feature descriptor methods. As a result, a larger crop size, a deeper sub-pixel layer, and high-resolution training images yield good performance.

We developed a web-based virtual laboratory system for electronic circuit experiments on the client/ server distributed environment. Through our virtual laboratory, the learners will be capable of learning the concepts and theories related to electronic circuit experiments and how to operate the experimental equipments such as multimeters, function generators, digital oscilloscopes and DC power suppliers. The proposed virtual laboratory system is composed of four important components: Principle Classroom to explain the concepts and theories of electronic circuit operations, Virtual Experiment Classroom to provide interactive multimedia contents about the syllabus of off-line laboratory class, Assessment Classroom, and Management System. With the aid of the Management System every classroom is organically tied together collaborating to achieve maximum learning efficiency. We have obtained several affirmative effects such as high learning standard, reducing the total experimental hours and the damage rate for experimental equipments.
