Recently, the Internet of Things is attracting attention as an important key technology of the 4th Industrial Revolution, and SW education using physical computing is suggested as a good alternative to supplement the problems raised by beginners in programming education. Among the many teaching tools that can be used for physical computing education, MODI is a modular manufacturing tool that anyone can easily assemble like Lego. MODI is a teaching tool that can improve learners' achievement by linking a self-linked block-type code editor called MODI Studio to lay the foundation for programming in a relatively small amount of time and immediately check the results in person. In this paper, a physical computing education method using MODI was designed to be applied to basic programming courses for programming beginners and applied to after-school classes for middle school students. As a result, it was found that students' interest and satisfaction were much higher in physical computing classes using MODI than in text-based programming classes. It can be seen that physical computing education that allows beginners to see and feel the results in person is more effective than grammar-oriented text programming, and it can have a positive effect on improving basic programming skills by increasing students' participation.

The healthcare industry is a digital healthcare that combines technology based on the 4th Industrial Revolution, dealing with information on individual health and medical care, and is a fusion of health care services and medical science and technology. It is questionable whether digital healthcare according to the paradigm change can be discussed by the concept of medical practice under the existing Medical Act. There is no clear definition of the concept of medical practice in the Medical Service Act, but the concept is established through precedents. In addition, under the Medical Service Act, the subject of medical practice is limited to medical personnel. However, digital healthcare sometimes diagnoses and treats diseases using digital technology by medical personnel. On the other hand, what is possible by non-medical personnel is digital healthcare. This is because digital healthcare is understood as a concept that includes health care such as exercise, eating habits, and weight control. For this reason, if the concept of medical practice under the "Medical Act" on digital healthcare is included, it is subject to criminal punishment for "unlicensed medical practice" prescribed in Article 27 of the "Medical Act". In the health and medical industry, digital transformation and convergence with information and communication technology are rapidly progressing. As a result, there is a need to newly define it as 'digitalized medical practice' or 'information and communication technology (ICT)-based medical practice' separately from existing medical practices. The concept of medical practice has variability, not a fixed and invariable concept. However, in response to this demand, it is not an infinite expansion of the concept of medical practice, but a request to reset its scope. Therefore, the concept of medical practice should be legislated by reflecting the demand of consumers for the medical service system.

The purpose of this study is to examine the seonbi spirit of Hoseo Confucian scholars in the 17th century centering around Noron's representative figures, Song Siyeol and Song Jungil, Mupyeonmudang's Gwon Si, and Soron's Yun Jeung. Criteria for being true seonbi and being equipped with seonbi spirit can be Chulcheojibyeon (出處之辯), Uirijibyeon (義利之辯), and Hwaijibyeon (華夷之辯). Considering these criteria, we can regard them as seonbi. Also, their seonbi spirit is differentiated from others in that they pursued the spirit of integrity, manners, and harmony more actively than anyone else. The seonbi spirit of Hoseo Confucian scholars in the 17th century is essentially characterized by the fact that it was the methodology and core virtue to reach Daedongsahoe through the realization of royal politics. In this sense, they strived to practice Uiri, the theoretical ground of it, carry out the project of Bukbeol, and establish Yehak aggressively. In this perspective, Hoseo Confucian scholars in the 17th century were true seonbi intending to apply and practice the spirit of Confucianism, for example, Sugichiin (修己治人), Iyonghusaeng (利用厚生), and DAedeokjohwa (大德調和), according to the historic mission of the time. Lastly, the seonbi spirit of Hoseo Confucian scholars in the 17th century can turn out to be an excellent alternative to eradicate social ills in this age. Particularly, if the current government uses seonbi spirit properly with the execution of 'the Act on the Promotion of the Humanities and Humane Spirit and Culture' or 'the Act on the Promotion of Character Education', it can form great contents for character education. Accordingly, this researcher here proposes a general model of character education using the seonbi spirit of Hoseo Confucian scholars in the 17th century and a convergent model of character education appropriate for the age of the fourth industrial revolution.

Recently, domestic schools are increasingly interested in environmental education related to COVID-19 and the severe climate crisis, as well as artificial intelligence education related to the 4th industrial revolution that is rapidly approaching us. In particular, AI education is highly likely to be applied to 5th to 6th graders of elementary school, so measures related to connection with 1st to 4th graders are needed. There are many students who are not proficient in computers in the lower grades of elementary school, so there may be many restrictions in using the currently used teaching aids. Therefore, this study tried to develop an artificial intelligence education program for the lower grades of elementary school to secure the linkage of artificial intelligence education. The theme of the program was developed based on the topic of environmental education, which has recently increased in interest. As for the educational method, considering the developmental stage of the lower grades of elementary school, the STEAM education method was used, which was fused with various subjects and unplugged using play and games without a computer. of the program. For validity verification, Lawshe (1975)'s content validity ratio (CVR) calculation formula was used. The verification results were analyzed to be suitable for the purpose of development of all programs. In the future, it is necessary to measure the degree of effectiveness by applying the program proposed in this study to the lower grades of elementary school.
