SW education has been incorporated into the regular curriculum since the 2015 curriculum due to the social changes caused by the 4th industrial revolution. The most important thing in SW education is the improvement of Computational Thinking. The study on the underprivileged who have little opportunity for education was relatively inadequate. In this study, CT competency of 135 underprivileged students were measured who were suffering from educational underprivileged. The underprivileged students were recruited from 15 local children's centers in Namyangju city and recruited 210 general students from B elementary schools in Namyangju city by setting up a selection criterion. As a result of comparing the CT competence between the two groups, it was found that the CT competence of the underprivileged students was lower than that of the general students, and suggested several implications with this result.

This study aims to explore the direction of Christian public practice in the post-COVID era, seeking to overcome the uncanny feeling caused by increased division and exclusion during the pandemic period. Firstly, we will investigate the unequal impact of COVID-19 on the labor market and examine ways to achieve economic justice in the post-COVID era. Subsequently, we will deliberate the role of Christianity in establishing publicness in the digital world and virtual spaces. Finally, viewing COVID-19 as a catastrophe caused by an anthropocentric worldview and exploitation driven by greed, we will explore the tasks of Christianity to overcome the crisis of the Anthropocene. Christian public practice should fulfill its mission of care and stewardship not only in social context but also in an ecological dimension. The author proposes "planetary citizenship education" for a harmonious relationship between human species and the Earth they inhabit.

Recently, the concept of zero trust has been introduced, and it is necessary to strengthen the security elements required for the next-generation security control system. Also, the security paradigm in the era of the 4th industrial revolution is changing. Cloud computing and the cybersecurity problems caused by the dramatic changes in the work environment due to the corona 19 virus continue to occur. And at the same time, new cyber attack techniques are becoming more intelligent and advanced, so a future security control system is needed to strengthen security. Based on the core concept of doubting and trusting everything, Zero Trust Security increases security by monitoring all communications and allowing strict authentication and minimal access rights for access requesters. In this paper, we propose a security enhancement plan in the security control field through a zero trust security model that can understand the problems of the existing security control system and solve them.

Today, due to the development of the 4th industrial revolution such as artificial intelligence, the security threat of the military organization is increasing. A study that can contribute to complying with military security is needed by studying the effects of influence factors occurring in this changing or newly emerging security environment on information security stress and security compliance behavior intention. In previous studies, task overload, task complexity, task uncertainty, and task conflict were extracted among environmental influencing factors that cause security stress. We empirically analyzed how these influencing factors affect security stress and whether they play a mediating role in security stress. As a result of the analysis, it was analyzed that the security stress was affected in the order of task overload, task conflict, and task uncertainty. Information security stress did not significantly affect security compliance behavior intention, but it was found to mediate the effect of task overload on security compliance behavior intention. This causes information security stress due to heavy security work in the military organization, which ultimately leads to lower security compliance behavior. Therefore, the security policy to manage this situation should be promoted first.

Recent advances in the 4th Industrial Revolution have accelerated the change of the working environment, such that the paradigm of education has been shifted in accordance with career education including the free semester system and the high school credit system. While the purpose of those systems is students' self-motivated career exploration, educational limitations for teachers and students exist due to the rapid change of the information on education. Also, education technology research to tackle these limitations is relatively insufficient. To this end, this study first defines three requirements that education technologies for the career education system should consider. Then, through data-driven artificial intelligence technology, this study proposes a data system and an artificial intelligence recommendation model that incorporates the topics for career exploration, courses, and majors in one scheme. Finally, this study demonstrates that the set-based artificial intelligence model shows satisfactory performances on recommending career education contents such as courses and majors, and further confirms that the actual application of this system in the educational field is acceptable.

In recent years, additive manufacturing (AM) processes have emerged as an important manufacturing technology for a multi-item small sized production to lead the 4th industrial revolution. The layer-by-layer deposition characteristics of AM process can rapidly produce physical parts with three-dimensional geometry and desired functionality in a relatively low cost environment. The goal of this paper is to investigate the applicability of AM process to appropriate technologies for developing countries. Through the review of examples of appropriate technology of the AM process, the possibility of a practical usage of the AM process for the appropriate technologies is examined. In addition, significant applications of the AM process to the appropriate technology are introduced. Finally, future issues related to production of physical parts for developing countries using the AM process are discussed from the viewpoint of the appropriate technology.

In the 4th industrial revolution, the blockchain that distributes and manages data through a P2P network is used as a new decentralized networking paradigm in various fields such as manufacturing, culture, and public service. However, with the advent of quantum computers, quantum algorithms that are able to break existing cryptosystems such as hash function, symmetric key, and public key cryptography have been introduced. Currently, because most major blockchain systems use an elliptic curve cryptography to generate signatures for transactions, they are insecure against the quantum adversary. For this reason, the research on the quantum-resistant blockchain that utilizes lattice-based cryptography for transaction signatures is needed. Therefore, in this paper, we propose a blind signature scheme for the blockchain in which the contents of the signature can be verified later, as well as signing by hiding the contents to be signed using lattice-based cryptography with the property of quantum resistance. In addition, we prove the security of the proposed scheme using a random oracle model.
