Recently, active research has been conducted on the metaverse as a new education platform. However, only a few studies analyze the specific characteristics of this platform from potential users' perspectives. Therefore, based on literature reviews and expert surveys on education, this study specifies the attributes and levels to be considered in developing metaverse education platforms. An online survey was conducted among university students in South Korea, and conjoint analysis was performed to propose the conditions for education platforms optimized for university education. The results revealed that 85% of respondents were willing to use metaverse education platforms, and preferred virtual classrooms that enable indirect experience in a web-based personal computer environment. In particular, the respondents showed a high preference for the education platforms that were available at $5 per month and used newly created three-dimensional avatar characters of themselves. This study is significant since its results have strategic implications for expanding the metaverse's use as a new educational space.

A variety of educational policies have been implemented to educate outstanding individuals who will lead the future and to adopt supporting systems. For the successful implementation of educational policies, it is crucial to identify the perception of teachers as main agents of education. This study conducted a survey with elementary teachers in Chungcheongbuk-do. The purpose of this study was to investigate teachers' perception on the major policies related to ICT(i.e., STEAM, Smart Education, Software Education, e-textbook, and EdudataSystem). This study also compared the distribution of teachers' perception on the policies. The results of the study indicated that teachers had relatively positive perception on the importance and the necessity of the policies. On the other hand, it was found that the levels of teachers' training experiences and readiness for teaching related to ICT were relatively low. In addition, the patterns of teachers' perception on STEAM, Smart Education and Software Education were similar. Based on the results, the study suggested that appropriate support and educational strategies for effective implementation of policies should be established.

The rapid growth of instructional videos repositories and their widespread use as a tool to support education have raised the need of studies to assess the quality of those educational resources and their impact on the quality of learning process that depends on them. Khan Academy (KA) repository is one of the prominent educational videos' repositories. It is famous and widely used by different types of learners, students and teachers. To better understand its characteristics and the impact of such repositories on education, we gathered a huge amount of KA data using its API and different web scraping techniques, then we analyzed them. This paper reports the first quantitative and descriptive analysis of Khan Academy repository (KA repository) of open video lessons. First, we described the structure of repository. Then, we demonstrated some analyses highlighting content-based growth and evolution. Those descriptive analyses spotted the main important findings in KA repository. Finally, we focused on users' interactions with video lessons. Those interactions consisted of questions and answers posted on videos. We developed interaction profiles for those videos based on the number of users' interactions. We conducted regression analysis and statistical tests to mine the relation between those profiles and some quality related proposed metrics. The results of analysis showed that all interaction profiles are highly affected by video length and reuse rate in different subjects. We believe that our study demonstrated in this paper provides valuable information in understanding the logic and the learning mechanism inside learning repositories, which can have major impacts on the education field in general, and particularly on the informal learning process and the instructional design process. This study can be considered as one of the first quantitative studies to shed the light on Khan Academy as an open educational resources (OER) repository. The results presented in this paper are crucial in understanding KA videos repository, its characteristics and its impact on education.

This study was made in order to provide the groundwork for the revised 7th education curriculum of primary and secondary education's facility criterion. Throughout this study, in which we may accomodate the new education curriculum, we prepare the guide for the standard criterion of the school systems in order to reflect the flexibility of various dictinctive regional education conditions and school qualities considering the purpose of new standard criterion of school facilities. Below is the summary of the study. Regular classroom's standard size, which is the basic module for the scale of the educational institution, accomodates current standards. Number of students per class is aimed to fit the standard number of the level of OECD member countries' in order to prepare for the future ; that is, 30 students in primary, secondary and high school to be the standard number of student per class, depending on the district conditions and construction point of time. It is advised that the number of extracurricular classrooms, according to the standard criterion of subject and hour allotment, to reflect the regional and institution's distinctive qualities by indicating the number of hours and classrooms including decimal points. That is to be done so that the founder and the interested parties of the institution, along with the architect can put to practical use when planning and designing the institution.

The Internet is a highly distributed and complex system consisting of billion devices and has become the field of various kinds of conflicts during the last two decades. As a matter of fact, various actors utilise the Internet for illicit purposes, such as for performing distributed denial of service attacks (DDoS) and for spreading various types of aggressive malware. Despite the fact that numerous services provide information regarding the threat level of the Internet, they are mostly based on information acquired by their sensors or on offline statistical sampling of various security applications (antivirus software, intrusion detection systems, etc.). This paper introduces proactive threat observatory system (PROTOS), an open-source early warning system that does not require a commercial license and is capable of estimating the threat level across the Internet. The proposed system utilises both a global and a local approach, and is thus able to determine whether a specific host is under an imminent threat, as well as to provide an estimation of the malicious activity across the Internet. Apart from these obvious advantages, PROTOS supports a large-scale installation and can be extended even further to improve the effectiveness by incorporating prediction and forecasting techniques.

Operating Systems is a discipline which handles abstract concepts and techniques. However, most of OS courses have been textbook-oriented theoretical classes. Theoretical classes lead to the decline in the understanding of a lecture and hurt their concentration. Many instructors have tried various ways to help students understand lectures and arouse interests. This paper describes the design and implementation of a web-based educational CPU scheduling simulator which enables learners to set up various situations and simulate scheduling processes using a web browser or a smart-phone. After utilizing the implemented simulator for the class, the survey result for 2014's students shows that it is useful as an educational tool which enhances the understanding of a lecture and develops their problem solving skills.

This paper examines the American role in shaping South Korean nation-building during the early Cold War by considering how the United States attempted to form South Korea's education and how Koreans responded to these efforts. It looks at education as an arena where "American" ideas such as democracy and liberalism were received, transformed, and utilized by Koreans. This study pays particular attention to the gap between American intentions and Korean expectations, as well as to the competition between American and Japanese systems, which explains the contradictory role America played in South Korean nation-building. In order to better assess the role of the United States in shaping South Korean education, this article considers the complex dynamics between the Japanese legacies, American influence, and Korean actors. Americans had exerted a great effect on Korean education since the beginning of their relationship. American missionaries, U.S. military government, and educational mission teams had all contributed to the expansion of educational opportunities for Koreans. Through the educational institutions that they established or helped establish, Americans tried to spread "their" ideas. In this process, Americans had to struggle with two obstacles: Korean nationalism and the legacies of Japanese colonialism. Many Koreans used American missionary schools for their own purposes and resisted U.S. military government's policies which ignored their desire for self-determination. American education missions had limited effect on Korean education due to the heterogeneous Japanese system that was still influencing South Korea even after liberation. The ways in which Americans have influenced the democratization of South Korea have not been simple. Although "American" democratic ideas reached Koreans through various routes, Koreans understood the "American" idea within their own historical context and in a way that fit their existing socio-political relations. Oftentimes suspicious of "American" democracy, Koreans developed their own concept of democracy. The overall American influence on Korean democratization, as well as on Korean education, was important but limited. While Americans helped Koreans build educational infrastructure and tried to transfer democratic ideas through it, Koreans actors and Japanese colonial legacies limited its impact.
