The purpose of this study is to analyze the utilization patterns of hydrogen fuel cells, which are the core of building a hydrogen economy, to identify the challenges of each type, to identify problems to be solved for the complete construction of a hydrogen economy, and to suggest ways to solve them. As a result, the use of hydrogen fuel cells was analyzed in terms of automobiles and power-plants. In the case of automobiles, except for the advantage of charging speed, it was analyzed that competitiveness was lower than that of cars. However, if the amount of platinum catalyst is gradually reduced through technological advances in nanotechnology, it is expected to be competitive in terms of cost. In the case of fuel cell power plants, the proportion of power generation was only 0.3% in 2018, but the proportion of power generation in 2022 is showing the rapid growth, close to 1.3%, which has higher power generation efficiency than solar or wind power. However, despite the many advantages, there are still concerns about the explosion and the problem of carbon dioxide generation in the case of certain hydrogen production methods. Finally, by analyzing the current hydrogen production method and identifying problems, a solution task for the complete construction of a hydrogen economy was presented. Representative methods include electrolysis, microbial decomposition, by-product hydrogen, and natural gas decomposition. Problems with each method are presented and development directions to produce hydrogen are presented.

The purpose of this study is to understand and utilize metaverse edutech. Edutech proposes an effective education system using digital media as a mixture of education and technology. Metaverse, which appeared in the technology-intensive era, is being studied and used as a future education in the educational system that has changed since the COVID-19. Metaverse technology will grow into an environment suitable for Blended Learning and On-demand Learning, which are referred to as optimized teaching methods after COVID-19, as content that is pivotal to the construction of virtual reality such as AI, AR, VR, and Blockchain. STEAM education has been attempted to enhance the effectiveness of education such as science and technology by making art as the contents, and the metaverse educational environment uses multi-complex artistic content to improve learners’ comprehension and thinking skills, resulting in high learning effect in non-face-to-face education. For this purpose, both teachers and instructors need education in metaverse literacy. Metaverse is not a tool, but a life environment. While technology and content in the edutainment era were tools of education, technology and content in the metaverse era is a life itself that blends the real and virtual worlds. Meta-learning at Meta School is necessary for the evolving educational ecosystem, and the role of content is important in unraveling current and future edutech service.

The purpose of this study is to develop various STEAM educational contents through the development and use of instructional models and textbooks for scienceoriented STEAM education. To this end, textbooks were developed so that classes could be conducted by organizing five instructional models of science-oriented STEAM education. The developed textbook confirmed the validity of the instructional model by conducting classes offline and online for elementary school students. The first instructional model is an AR anatomy special lecture, which uses the AR app to observe the appearance of four creatures, observe the inside of the creature through dissection, and learn the characteristics of the creature. The second instructional model is SCIENCE MAGIC, which learns scientific principles using magic tools and performs magic performances in front of friends through magic practice. The third instructional model is a class that conducts exploration that can solve inconveniences in life with special lectures on creative inventions and devise creative invention ideas through creative thinking techniques. The fourth instructional model is a special lecture on robot coding, which explores sensors of automobile robots and solves missions using sensors by coding. The fifth instructional model is a science dictionary that is made with curious questions and answers from students who have learned science by experimenting with novel methods and scientific principles that can solve inconveniences in life. The instructional model of science-oriented STEAM education developed in this way will be able to improve students’ core competencies.

The purpose of this study is to explore the possibility of barrier-free digital media content to create an inclusive cultural and artistic environment that pursues diversity without discrimination between the disabled and non-disabled in the digital-based culture and art environment that is rapidly changing due to the corona pandemic. The subject of this study is “Burning Bunny’s” (2019, 2022) barrier-free video contents and services, which were tried at the Interdisciplinary Arts Festival. The research method was divided into digital image contents produced by collaboration between disabled artists and non-disabled artists and barrier-free services in online performance streaming. First, barrier-free digital contents were introduced in auditory-oriented performances to help hearing impaired people enjoy music. To this end, synesthetic video content was produced and distributed through collaboration between disabled and non-disabled artists. Second, real-time performance streaming with barrier-free services such as real-time subtitles and dancing sign language interpretation was provided. As a result of the study, the digital media contents and services of 「Burning Bunnys」 (2019, 2022) attempted at the Interdisciplinary Arts Festival actively interact with the disabled through digital technology, and presented as a case of digital technology convergence activity field for disabled artists to develop in the future. This suggests that it is time to expand and redefine the meaning of barrier-free digital media content necessary to create an inclusive cultural and artistic environment in the future post-corona era in a digital technology-oriented cultural society that is strengthened through this.
