Purpose: To describe pediatric coronavirus disease 2019 (COVID-19) cases after the reopening of schools in the Republic of Korea and their transmission routes. Methods: All case report forms and epidemiologic investigation forms for children aged 3-18 years reported as COVID-19 cases to the National Notifiable Disease Surveillance System from May 1 to July 12, 2020, were reviewed. Results: After the schools were reopened in May 2020, a total of 127 pediatric COVID-19 cases were confirmed until July 12. Of these, 59 children (46%) were exposed to severe acute respiratory syndrome coronavirus 2 through family and relatives, followed by 18 children (14%) through cram schools or private lessons, 8 children (6%) through multi-use facilities, and 3 children (2%) through school. Conclusions: The present data do not suggest an increased risk of COVID-19 transmission in the context of stringent school-based infection prevention measures introduced across the country.

2023년 8월 3일 다중이용시설과 운송시설이 맞닿아 있는 서현역 부근의 다중이 밀집한 장소에서 차량돌진 및 흉기난동의 묻지마 범죄가 발생하였다. 차량을 인도로 몰아 보행자를 들이받은 뒤 백화점 내부로 들어가 흉기를 휘둘러 차량돌진으로 5명, 흉기난동으로 9명의 피해자가 발생하였다(리차드김, 2023). 서현역의 묻지마 범죄 이후, '살인예고 지도' 서비스의 등장하면서 많은 이용객이 상시 붐비는 번화가 및 백화점 등의 다중이용시설을 이용하는 시민들의 불안감이 전국적으로 크게 확산하고 있다(김잔디 & 최윤선, 2023). 급격히 늘어나는 국민의 불안감으로 정부에서는 '묻지마 범죄'를 '이상동기범죄'로 명명하고 근절을 위해, 사실상 테러와 비슷한 수준의 강력한 대책을 추진하고 있다(강은민, 2023). 이상동기범죄에 따른 강력한 대책으로 국무조정실(대테러센터), 경찰청 등 관계부처의 다중이용시설 대한 안전대책들이 강구되어지고 실정에서 「경비업법」에 따라 시설의 위험발생을 방지하는 업무를 담당하고 있는 민간 경비원에게 이용객의 안전을 보호하고 피해를 최소화하기 위한 일선 역할이 중요해졌다. 하지만, 이상동기범죄에 대한 일선의 초동대응이 인력과 장비, 정당방위에 대한 법제도의 뒷받침 미흡 등으로 인해 민간 경비원의 실질적인 대응이 어려운 실정이다. 많은 사람의 왕래가 있는 다중이용시설에서의 민간 경비원 최소 경력배치 기준, 현행범 제압을 위한 무기사용 기준, 이용객 보호를 위한 경비원 위력 사용 기준 등의 제도적으로 마련되어 있지 않아 민간 경비원이 범죄로부터 시설 이용객을 보호하는 것은 쉽지 않은 것이 현실이다. 따라서 본 연구에서는 다중이용시설 묻지마 범죄 등의 위험성과 민간 경비원의 무기사용과 관련한 법제도적 한계점을 고찰하여, 이에 대한 개선방안을 제시하고자 한다.

Foam block, popularized as the self-interior goods, is susceptible to fire since the main material is the polyethylene flammable synthetic resin. However, it is widely used in homes, offices, and multi-use facilities. In order to understand the fire characteristics of the foam block, two kinds of foam blocks sold in the market (non-fire retardant and fire retardant) were evaluated according to standard of KS F 5660-1 (Reaction to fire test). In addition, the hazard analysis of the gas generated by the combustion of the specimen was performed using the FTIR gas analyzer. The cone calorimeter test showed that the ignition and flame combustion of both two specimens were burned as soon as the radiant heat blocking device was removed, and it was confirmed that the flame could become a rapid propagation factor during the fire. The analysis of the combustion gas through the FTIR gas analyzer showed that both the carbon dioxide and carbon monoxide classified as the common combustion gases and the acrolein, ammonia, and hydrogen cyanide causing serious damage to the human body were detected substantially. This study showed that a foam block product has high ignitionability and generates toxic gases. Hence, it is urgently required to establish the standards used for properly classifying the combustion characteristics of the material on the basis of the use conditions of a foam block product and to prepare the standards on the purpose of use.

As for the anti-terrorism bills, which were submitted to the National Assembly, the mobilization of anti-terrorism commando, which was designated or established by the National Defense Minister, is mobilized the military troops without being based on marital law in light of the constitutional law, thereby possibly violating the constitution, first of all, with regards to mobilization of anti-terrorism commando, which was formed with military troops. The anti-terrorism commando is the military force, which was trained professionally for the anti-terrorism activity. Thus, the violation of human rights may be greatly reduced rather than what general soldiers are putted in the public-order activity such as anti-terrorism. However, it is thought to be desirable to make it possible for the input of special forces, which were trained professionally in relation to anti-terrorism activity, through constitutionally revising the constitutional law. As for the provision of 'support for military troops' in the anti-terrorism bill, what is a case that the nation's important facilities and multi-use facilities are difficult to be protected from terror with the anti-terrorism commando and police force needs to be constitutionally regarded as resulting in reaching the level enough to correspond to 'a state of national emergency equivalent to wartime incident.' Thus, enacting the future anti-terrorism law, it is thought to be unnecessary for having the provision of 'support for military troops' with receiving criticism obstinately for possibly violating the constitution.

The Four Major Rivers Restoration Project of is the multi-purpose green growth project in South Korea. Some of the project was progressed by K-water and was declared complete on October 21, 2011. The Four Rivers Restoration Project of Korea was designed to be a packaged project that aims to resolve water-related problems such as floods and droughts and revitalize Korean public spaces near the water. K-water have applied the latest ICT(Information and Communication Technology) for the operating management of 4 Rivers Project facilities. We also have applied ICT for integrating drinking water production facilities. Applying these ICT, we have many experience for integrated water resources management, so we proposed. The first is that the big data collected should be analyzed for making decisions and taking actions while considering multiple viewpoints of how water should be managed. The second is that the new MMI(Man Machine Interface) program should be developed to use domestic needs and promote ease of maintenance for the integrated operation. The third is that the standardization of communication protocol is needed for seamless communication between equipments.

As large-scale buildings, skyscrapers, and multi-purpose buildings recently increase in numbers dramatically, the internal space of such buildings becomes more and more large and complicated accordingly. Since such structures usually accommodate a number of random people, the potential possibilities of disastrous tragedies are high, and the rates of injury and physical damage caused by the complicated system of the building also increase as well. However, most of the shelter designs of the existing buildings are based on the specifications according to the assigned laws and involved regulations. In this case, only general criteria are referred to regardless of the characteristics of each structure while other disaster-related features are not taken into consideration sufficiently. Since any actual fire may cause a terrible calamity, in such plans, shelter inducement can be neither safe nor effective. Thus, this study examines and analyzes currently run disaster prevention systems and shelter inducement facilities with COEX Mall as its subject, and analyzes the responding system to each situation based on the fire scenarios by means of As-Is Model. Through this analysis, presented are the measures to solve the problems of current disaster prevention systems and to improve shelter inducement methods effectively.

Purpose: On August 16, 2021, the Taliban established the Taliban regime after conquering capital Kabul of the Afghan by using the strong alliance of international terrorist organizations. The Taliban carried out terrorism targeting the Korean people, including the kidnapping of Kim Seon-il in 2004, the abduction of a member of the Saemmul Church in 2007, and the attack on Korean Provincial Reconstruction Team in 2009. Therefore, this research has shown the possibility of Taliban terrorism in Korea. Method: Based on the statistical data on terrorism that occurred in Afghanistan, Taliban's various terrorist activities such as tactics, strategies, and weapons are examined. Consequently, the target facilities and the type of terrorist attacks are analyzed. Result: The Taliban are targeting the Afghan government as their main target of attack, and IS and the Taliban differ in their selection of targets for terrorism. Conclusion: From the result of this research, we recommend Korea need to reinforce the counter terrorism system in soft targets. Because If the Taliban, which has seized control of Afghanistan, and IS, which has established a worldwide terrorism network, cooperate to threaten domestic multi-use facilities with bombing, the Republic of Korea may face a terrorist crisis with insufficient resources and counter-terrorism related countermeasures.

This study was conducted based on the need to establish an operational plan following the establishment of the Okcheon-gun Daily Life Culture and Sports Center Library, and for the users of public libraries in Okcheon-gun, the functions and roles of the Okcheon-gun Library, collection related to operational direction, user service related activation, library usage related status survey, preference for the future use and perception of desired services were surveyed. Based on the results of the perception survey, the direction required by the Okcheon-gun residents for the Library was identified, and the research results are as follows. As a result of the study, first, when establishing a collection plan, the data types ought to be based on the printed materials and the multi-media materials to reflect the needs of the users, and it may also be necessary to collect them in consideration of the subject areas including literature, art, history, and technical sciences. Second, to provide various information services, it would be necessary to establish an overall information service plan, and it was identified that it would be necessary to develop various information services according to the user preferences and provide cooperative services. Third, it was determined that the programs appropriate for the various subjects and age groups should be continuously expanded moving forward in consideration of the larges demand for programs by the residents of Okcheon-gun. Fourth, new constructions and spatial improvements are needed, and the overall preference for open spaces was significant. In the case of cultural space, the preference for youth cultural facilities, convenience facilities for residents, infinite loss of imagination, and the (experiential) exhibition halls turned out to be large.

In order to assess the safety diagnosis and grouting reinforcement effect of old reservoir facility, local governments and public offices mainly use electrical resistivity survey. However, electrical resistivity survey is a qualitative evaluation that varies the resistivity value by various exploration conditions. It is also difficult to grasp the stiffness change directly related to the stability of reservoir, thus an electrical resistivity survey is not applicable to continuous stability monitoring after grouting. The purpose of this study is to investigate and validate the quantitative evaluation of reinforcement effect of reservoir with cement grouting through shear velocity (Vs), which is closely related to the stiffness (${\mu}$) of the ground. This study was carried out on two reservoir facilities. The reinforcement effect was evaluated by comparing the permeability test, standard penetration test, down-hole test and MASW(Multi-channel Analysis of Surface wave) survey before and after cement grouting. Shear wave velocity changes before and after grouting were analyzed by phase velocity difference and inversion analysis, respectively, and the reliability of the analytical results was evaluated by comparing with field test results. Shear wave velocity increases to 5~10% in case of the D levee, and 10~20% in the levee of H reservoir. These results are showed similar pattern to the field test results.

The purpose of this study is to analyze the usage behavior of Seoullo 7017, the first public garden in Korea, to understand the usage status by analyzing blogs, and to present usage behavior and improvement plans for Seoullo 7017. From June 2017 to May 2020, after Seoullo 7017 was open to citizens, character data containing 'Seoullo 7017' in the title and contents of NAVER and·DAUM blogs were converted to text mining and socialization, a Big Data technique. The analysis was conducted using social network analysis. The summary of the research results is as follows. First of all, the ratio of men and women searching for Seoullo 7017 online is similar, and the regions that searched most are in the order of Seoul and Gyeonggi, and those in their 40s and 50s were the most interested. In other words, it can be seen that there is a lack of interest in regions other than Seoul and Gyeonggi and among those in their 10s, 20s, and 30s. The main behaviors of Seoullo 7017 are' night view' and 'walking', and the factors that affect culture and art are elements related to culture and art. If various programs and festivals are opened and actively promoted, the main behavior will be more varied. On the other hand, the main behavior that the users of Seoullo 7017 want is 'sit', which is a static behavior, but the physical conditions are not sufficient for the behavior to occur. Therefore, facilities that can cause sitting behavior, such as shades and benches must be improved to meet the needs of visitors. The peculiarity of the change in the behavior of Seoullo 7017 is that it is recognized as a good place to travel alone and a good place to walk alone as a public multi-use facility and group activities are restricted due to COVID-19. Accordingly, in a situation like the COVD-19 pandemic, more diverse behaviors can be derived in facilities where people can take a walk, etc., and the increase of various attractions and the satisfaction of users can be increased. Seoullo 7017, as Korea's first public pedestrian area, was created for urban regeneration and the efficient use of urban resources in areas beyond the meaning of public spaces and is a place with various values such as history, nature, welfare, culture, and tourism. However, as a result of the use behavior analysis, various behaviors did not occur in Seoullo 7017 as expected, and elements that hinder those major behaviors were derived. Based on these research results, it is necessary to understand the usage behavior of Seoullo 7017 and to establish a plan for spatial system and facility improvement, so that Seoullo 7017 can be an important place for urban residents and a driving force to revitalize the city.
