Since the emergence of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) in December 2019, a small number of coronavirus disease 2019 (COVID-19) cases in neonates have been reported worldwide. Neonates currently account for only a minor proportion of the pediatric population affected by COVID-19. Thus, data on the epidemiological and clinical features of COVID-19 in neonates are limited. Approximately 3% of neonates born to mothers with COVID-19 reportedly tested positive for SARS-CoV-2. Current limited data on neonates with COVID-19 suggest that neonatal COVID-19 shows a relatively benign course despite a high requirement for mechanical ventilation. However, neonates with pre-existing medical conditions and preterm infants appear to be at a higher risk of developing severe COVID-19. The greatest perinatal concern of the COVID-19 pandemic is the possibility of vertical transmission, especially transplacental transmission of SARS-CoV-2. Although direct evidence of the vertical transmission of SARS-CoV-2 is lacking, its possibility during late pregnancy cannot be ruled out. This review summarizes available case studies on COVID-19 in neonates and introduces what is currently known about neonatal COVID-19 with focus on its vertical transmission.

The coronavirus disease-19 (COVID-19) vaccine is expected to play an important role in stopping the pandemic. Studies show that COVID-19 vaccines are effective at keeping you from getting COVID-19. Getting a COVID-19 vaccine will also help keep you from getting seriously ill even if you do get COVID-19. Efforts to find an effective vaccine against severe acute respiratory syndrome coronavirus 2 have progressed unprecedentedly through active support from public research grants and private-public partnership programs. Clinical studies have been actively conducted, and some vaccines are being vaccinated with approval for urgent use. The WHO has approved and supplied the Pfizer-BioNTech COVID-19 vaccine and the Oxford-AstraZeneca COVID-19 vaccine. In Korea, the Oxford-AstraZeneca vaccine was approved for urgent use, and vaccination began on February 26, 2021. In this paper, the efficacy and side effects of each vaccines and the effect on pilots and air traffic controllers related to COVID-19 vaccination were investigated in terms of aviation medicine.

Coronavirus disease 2019 (COVID-19) is currently in progress. Although it is difficult to predict the end of currently increasing COVID-19, it is expected to last for a long time. The COVID-19 is making a lot of changes. Due to physical distancing and living distancing, non-contacts such as wearing facial masks, online lectures, online medical services, telecommuting, and telemarketing are becoming common. In the era of post-COVID-19, online and offline will coexist. Many countries following China's lockdown strategy, which is agreed with the World Health Organization, should be changed to Taiwan's facial mask strategy for reducing the economic problems. The prolonging COVID-19 will add to the economic difficulties, and the US-China confrontation will be difficult to rebound the global economy. COVID-19, such as plaque, smallpox, and Spanish influenza, will be a historical momentum. How to respond to the crisis of COVID-19 and post-COVID-19 will determine the future of the world and Korea.

Background: There are regional variations in the incidence of coronavirus disease 2019 (COVID-19), which means that some regions are more exposed to the risk of COVID-19 than others. Therefore, this study aims to investigate regional variations in the incidence of COVID-19 in Korea and identify risk factors associated with the incidence of COVID-19 using community-level data. Methods: This study was conducted at the districts (si·gun·gu) level in Korea. Data of COVID-19 incidence by districts were collected from the official website of each province. Data was also obtained from the Korean Statistical Information Service and the Community Health Survey; socio-demographic factor, transmission pathway, healthcare resource, and factor in response to COVID-19. Community risk factors that drive the incidence of COVID-19 were selected using a least absolute shrinkage and selection operator regression. Results: As of June 2021, the incidence of COVID-19 differed by more than 80 times between districts. Among the candidate factors, sex ratio, population aged 20-29, local financial independence, population density, diabetes prevalence, and failure to comply with the quarantine rules were significantly associated with COVID-19 incidence. Conclusion: This study suggests setting COVID-19 quarantine policy and allocating resources, considering the community risk factors. Protecting vulnerable groups should be a high priority for these policies.

The COVID-19 global health crisis has affected the mental and psychological health and well-being of the people around the world. However, little is known about the impact of COVID-19 among Filipino teachers. This study was conducted to determine the impact of the COVID-19 pandemic on the quality of life (QoL) of professional teachers in the Philippines. A descriptive cross-sectional study was used involving 139 licensed professional teachers. The COVID-19 Impact on Quality of Life (COV19-QoL) was the primary measure used in this study. Descriptive statistics, t-test, and one-way ANOVA were the statistical tools employed to analyze the data. Results indicated a moderate COVID-19 impact on the QoL of the teachers. There was a significant difference in the impact of COVID-19 on QoL by degree program. However, the impact of COVID-19 on QoL did not significantly differ by age, sex, marital status, employment status, monthly salary, presence of a COVID-19 case near their residence, personal knowledge of someone who was infected or died of COVID-19, presence of a medical condition, and perceived threat. The psychological well-being and QoL of teachers must be recognized and teachers must be provided with support as they continue to adapt to the impact brought by the COVID-19 pandemic. This study contributes to the growing literature on the impact of the pandemic.

Coronavirus disease 2019 (COVID-19) has had a significant impact on our society as a whole. The COVID-19 pandemic is not only a health crisis, it is also an economic, social and humanitarian crisis. Considering the dramatic global economic and social impact that the crisis has engendered, the aviation system is standing on the doorstep of rapid transformation. In particular, the impact on the aviation and travel industries is enormous. Air travel to most countries has been suspended and blocked. Looking at Korea's current situation, COVID-19 has wholly changed the aviation industry. As COVID-19 spreads around the world, countries have come up with aviation safety measures. Infectious disease safety measures were established to protect passengers and crew members, and countries with collapsed medical systems extended the validity period for aviation medical examinations. In Korea, on August 11, the Ministry of Land, Infrastructure and Transport provided guidance on medical measures related to COVID-19 through an official letter of "Notification of cautions for pilots and air traffic control officers (ATCO) when COVID-19 is confirmed". Overseas countries such as the United States and the United Kingdom have announced regulations for aviation medical examination regulations in relation to COVID-19, and have set standards for returning to aviation after COVID-19 is confirmed. In this paper, we would like to investigate the regulations for aviation medical examination related to COVID-19.

This study aims to examine the effects of users' perceptions of COVID-19 risk on their seeking and processing of relevant information as COVID-19 emerges and spreads worldwide in 2019. We apply the risk information seeking and processing model (RISP Model) to verify whether users' COVID-19 related information seeking and processing behaviors have a positive effect on their preventive and information sharing behaviors. To achieve this research goal, an online survey was conducted with about 400 of social media users. The users' perceptions of risk for COVID-19 increased their perceived insufficiency of COVID-19 information. In addition, the perceived insufficiency of users' information formed a positive relationship with seeking and searching of information behaviors. The processing of COVID-19 related information has increased related preventive behaviors and sharing of information through social media. While searching for information related to COVID-19 prompted personal information sharing behaviors, it did not significantly affect preventive behaviors. Accordingly, in order to promote COVID-19 preventive behaviors as well as overall user health-related behaviors it can be inferred that additional measures are needed in addition to pursuing relevant information.

본 연구의 목적은 전쟁이론 관점에서의 COVID-19를 분석하고, 이를 극복할 수 있는 방안을 모색하는 것이다. 전쟁이 국제적인 상황에 따라 그 패러다임과 국가 위기관리 시스템을 변화시키는 것과 마찬가지로 최근의 COVID-19도 언택트 문화를 특성으로 하는 New Normal의 시대를 야기하고 있다. COVID-19와 관련된 학술적 연구가 주로 의학, 관광, 경제적인 분야에 초점이 맞추어졌지만, 군사학이나 전쟁이론 측면에서의 연구는 미진한 형편이다. COVID-19가 국가의 생명과 재산상에 막대한 위협을 주고 있기 때문에 전쟁이론 측면에서 COVID-19를 극복해야 할 적으로 간주 할 수 있으며, 전쟁이론 중에 전쟁의 속성과 양상, 승리요인 측면에서 현 COVID-19 상황에 대해 분석이 이루어진다. 정석적 분석 및 설문을 통한 정량적 결과 COVID-19는 전쟁의 속성 및 양상 측면에서 실제 전쟁과 매우 유사한 점이 존재하기 때문에 과거 전쟁의 승리요인을 바탕으로 COVID-19의 효과적인 극복 방안을 도출할 수 있다. 또한 분석적계층과정(AHP)을 통한 극복요인의 우선순위를 분석한 결과 명확한 목표와 동맹관계 확립이 COVID-19를 성공적으로 극복하기 위한 우선 시 되어야 함을 알 수 있다.
