This study aims to review the characteristics of specialized classrooms for governmental secondary schools in the Japanese Colonial Era by analyzing architectural drawings collected by National Archives of Korea. The results of this study are summarized as follows 1) Under the influence of Japanese science promotion of that time, specialized classrooms for science were considered as one of essential facilities. Typically exclusive specialized classrooms were assigned to two major science subjects : physics-chemistry and biology. 2) To science specialized classrooms, ancillary rooms for preparation, experiment equipment and specimen were attached and science lecture room with stepped floor was planned additionally only for the lecture on theories and the demonstration of experiment. 3) Specialized classrooms for science were zoned independently of other facilities because of the special equipments and safety. 4) Art rooms were common to both boys' and girls' schools but concerning music rooms, girls' schools had special concerns, whereas boys' schools did not. 5) Specialized classrooms for homemaking subject of girls' school were as much important as those for science subjects of boys' school. 6) Some early-established Korean boys' schools had handicraft rooms which were the symbol of vocational education-oriented, unequal policy on Koreans. Though not general cases, specialized classrooms for geography-history were planned for Japanese boys' school. Restricted to governmental secondary schools but considering the uncommon state of specialized classrooms of that time, these characteristics show conditions of early time when special classrooms were introduced into Korea.

The purpose of this study is to identify the chaotic state of school education caused by COVID-19 and to seek the role of the principal in responding quickly to the national crisis. To solve this problem, 34 elementary school principals in Seoul, Busan, Daegu, Daejeon, and Jeju were surveyed with open questions through the first SNS on what leadership is needed to cope with COVID-19, and the second in-depth interview was conducted through phone calls. In the New Normal era, principal's leadership requires insightful and responsible leadership in supporting educational activities, class support, and problem prevention that can occur due to rapid response to crisis situations, rapid budgeting and input, and promotion of teacher-to-teacher communication, according to a survey. In crisis situations such as COVID-19, it is necessary to establish a role of principal for schools to cope stably and to establish an educational environment in which students learn in a safe environment. For this, national and educational policy support is needed.

The purpose of this study is to determine what children's rights to play are. For this purpose, we extracted the core contents of schools' play environments and we developed a checklist that schools can use to evaluate their own play environments. We reviewed the UN Committee on the Rights of Children and the General Comments No. 17. Through this process, we found 16 core contents that the play environment should have. We conducted focus group interviews with children, parents and teachers, who are principle people involved with school play. The focus group interviews discussed the basic elements of the school play environment. The contents' validity was reviewed by a group of professionals. Based on this, we created an evaluation checklist with 10 major areas of the school play environment. The 10 areas of the school play environment evaluation scale are as follows. The ten areas of the play environment assessment scale for the school environment to ensure children's right to play are sufficient play time, sufficient play space, a child's best interests and the child's participation, nondiscrimination, diversity and freedom, challenge and adventure, safety, school policy, the play has an educating component, and community cooperation.

The study aims to find the characteristics of children's crossing behavior on crosswalk in school zones. It considers accident occurrence and physical form of school zones. Seven elementary school zones were investigated. Using data collected by field observation and video recording, statistical analysis, CHAID algorithm analysis, and pattern analysis were performed. As a result, it was found that children's waiting, attention and distraction were related to the accident occurrence. While 69.1% children showed waiting-before-crossing behavior in low-accident occurrence crosswalk, 83.6% children showed non waiting-before-crossing behavior in high-accident occurrence crosswalk. Moreover, the ratio of waiting, attention behavior was found to be higher when the width of the crosswalk was wide and the distance from the school's entrance to the crosswalk was long. These research findings showed that children's behavior-oriented approach was required to improve safety in school zone.

In this study, a smartphone utilization system was designed to explore ways to use smartphones owned by more than 95% of Korean teenagers in school classes. First, the necessary functions were selected based on the factors related to adolescents and the factors of distraction, dependence, motivation, and cooperation in the preceding studies on the use of smartphone classes, and then three versions of the application were composed according to the educational roles of students, teachers, and parents. By using these applications, students can learn self-study, motivate learning, and actively interact, teachers can be more closely with students and facilitate lessons while giving detailed feedback, and parents can check the student's safe learning using smartphones. It is hoped that this measure will help to increase the educational effect by activating the use of smartphones in school classes.

In recent years, there have been frequent incidents of invasion of national defense networks by insiders. This trend can be said to disprove that the physical network separation policy currently applied by the Korea Ministry of National Defense can no longer guarantee military cyber security. Therefore, stronger cybersecurity measures are needed. In this regard, Zero Trust with a philosophy of never trusting and always verifying is emerging as a new alternative security paradigm. This paper analyzes the zero trust establishment trends currently being pursued by the US Department of Defense, and based on the implications derived from this, proposes a zero trust establishment plan tailored to the Korean military. The zero trust establishment plan tailored to the Korean military proposed in this paper includes a zero trust establishment strategy, a plan to organize a dedicated organization and secure budget, and a plan to secure zero trust establishment technology. Compared to cyber security based on the existing physical network separation policy, it has several advantages in terms of cyber security.

Favorable policies for freight vehicles (i.e., trucks), such as exclusive "Truck-ways," have been proposed, and at the same time restricted policies for freight vehicles have been suggested because transportation of goods by truck aggravates traffic congestion and environmental conditions in urban areas. This study discusses the limitations of assessment processes for freight vehicle route management systems which have been carried out from limited perspectives such as physical distribution efficiency and traffic circulation. The objective of this study is to propose an assessment method of truck route management systems in urban areas which includes more varied criteria. This research modified the two existing assessment indices of physical distribution efficiency and traffic circulation. In addition two new assessment indexes are proposed: (i) exposure indices for population directly influenced by nitrous oxide, a representative pollutant, and (ii) a friction index between trips for attending elementary school and freight vehicle trips. It was found that from the perspective of physical distribution efficiency and traffic circulation, the "before" alternative is better than "after". However, from the aspect of traffic safety and environmental impacts the "after" alternative is better than "before". It is expected that the proposed evaluation method in this study would be useful when identifying reasonable policies for truck route management in urban areas.

Recently, school violence problem has increased serious. And this is not only an individual issue but also this is a social problem. Realistically, not only physical violence, cyber violence using the smartphone is very serious. And if the elementary school students are exposed to cyber violence, it becomes even more serious problem. Therefore, we proposed an Smart Monitoring app that protect the smart safety such as as a countermeasure against cyber violence to elementary school students. This Conversion Smart app can support grasp service for children using location based service on the smartphone when he will come to the home. And it can support another service that abuse or vulgar language in messenger. Grasps the degree of use of the language that is prohibited friendship in elementary school through this process, it can be derived. And we have future works that is the search rate and response time an inappropriate word on the proposed system.

Sophisticated Air Navigation System has contributed to enhancing the capacity of airspace capacity, leading to an efficient airspace environment. However, it has acted as a factor increasing the probability of collision. When an aircraft fails to maintain vertical separation and instead exhibits lateral positional errors, it does not necessarily lead to a collision. However, as the lateral positional accuracy increases, the randomness of aircraft positions decrease, resulting in an elevated probability of collisions. Consequently, The International Civil Aviation Organization has introduced Strategic Lateral Offset Procedures(SLOP), intentionally deviating aircraft from the centerline of airways. Likewise, South Korea also operates Offset procedure. The Y579 was operated using the Offset before its conversion to a dual airway and the analysis of the Offset track revealed that it was being operated similarly to a unidirectional dual airway. This paper develops a safety assessment methodology applicable to unidirectional dual airways, and applies it to perform a safety assessment of the Y579 Offset procedure.
