지난해 10월부터 시작된 오리사육제한이 올해 2월까지 4개월간 실시됐다. 사육제한이 끝난 농가들이 기지개를 필 무렵, 코로나바이러스감염증-19(COVID-19, 이하 코로나19)가 터졌다. 3년간 시행된 오리사육 제한으로 생산비를 밑돌면서 오리를 생산해 온 오리업체들은 이번 사육제한을 끝으로 발돋움하려는 청사진을 그려놓았다. 그러나 세계를 '정지'상태로 만든 코로나19로 오리산업은 다시 답보상태에 빠졌다. 올해 외식산업에서의 '오리산업 전성기'를 꿈꾸며 오리자조금이 추진한 '오리 중량판매' 등의 시책은 코로나19로 두문불출하며 외식을 줄인 소비자들에게 제대로 선을 보이지도 못한 상태다. 외식시장의 대부분이 수입육으로 이뤄져 있는 대부분의 축종들은 가정소비가 늘어나면서 오히려 때아닌 특수를 누렸지만 외식수요로 생오리의 대부분을 판매하던 오리산업은 '나홀로' 피해를 입은 축종이 돼 버렸다. 오리사육 제한으로 입은 피해에서 아직 벗어나지도 못한 오리산업, 코로나19는 오리산업에 얼마만큼의 피해를 준 것일까? 이 패해는 언제 끝나는 것일까?

코로나 바이러스가 2019년 12월 처음 중국 우한에서 발생한 뒤 우리나라를 포함한 전 세계로 확산되어 있다. 각 나라에서는 사전차단을 위한 방역과 격리 등 바이러스의 확산을 막기 위하여 온 힘을 다하고 있으며, 우리나라 역시 국가 차원에서 대응정책을 펼치고 있다. 이에 코로나 바이러스를 대비한 정부의 대응정책과 긴급재난문자를 이용한 상황지원 현황, 그리고 포스트 코로나 시대의 긴급재난문자 발전방향에 대하여 살펴보고자 한다.

COVID-19 has spread seriously around the world in 2020 and it is still significantly affecting our whole daily life. Currently, the whole world is still undergoing the pandemic and South Korea is no exception to it. During the pandemic, South Korea had several events that prevented or accelerated its spread. To establish the prevention policies for infectious diseases, it is very important to evaluate the intervention effect of such events. The susceptible-infected-removed (SIR) model is often used to describe the dynamic behavior of the spread of infectious diseases through ordinary differential equations. However, the SIR model is a deterministic model without considering the uncertainty of observed data. To consider the uncertainty in the SIR model, the Bayesian approach can be employed, and this approach allows us to evaluate the intervention effects by time-varying functions of the infection rate in the SIR model. In this study, we describe the time trend of the spread of COVID-19 in South Korea and investigate the intervention effects for the events using the stochastic SIR model based on the Bayesian approach.

Coronavirus disease 2019 (COVID-19) presents as a mild-to-moderate respiratory illness in most children. However, a small proportion of children with COVID-19 develop severe or critical illnesses. Although pediatric clinical trials for the treatment of COVID-19 are sparse, some drugs are available for children and adolescents with severe COVID-19. This review summarizes clinical data focusing on antiviral agents and immunomodulators for use in treating COVID-19. In addition, current recommendations for therapeutics for children and adolescents with COVID-19 are discussed.

코로나바이러스-19 팬데믹 이후 매일 수만 명의 환자가 발생하고 있다. 보건당국은 사람들의 생활 안전을 보호하기 위해 공항, 정류장 등 공공장소에서는 반드시 마스크를 착용하라고 지시하고 있다. 마스크를 착용하는 목적은 감염으로부터 신체를 보호하고 바이러스 전파와 확산을 막기 위한 것이다. 공공장소에서는 많은 인원에 대한 일괄적인 마스크 착용 검사를 하기 어렵고, 육안으로 확인하는 마스크 착용 검사 방법은 인파가 몰리는 장소에서 검사 효율이 떨어지며 누락되는 경우도 많이 발생한다. 본 연구에서는 입력 이미지에 존재하는 얼굴 영역을 YOLOv4와 YOLOv5 모델을 통해 예측하여 마스크의 착용 여부를 판단하되, 앙상블 기법을 적용하여 보다 효과적인 BB(Bounding Box) 추출 및 마스크 착용 탐지 기법을 적용한다. 따라서 공공장소의 마스크 착용실태를 효과적으로 모니터링 할 수 있는 방법을 제안한다.

Coronavirus disease 2019 (COVID-19), which was a global pandemic caused by severe acute respiratory syndrome corona virus 2 (SARS-CoV-2), is still a serious public health problem. COVID-19 causes various symptoms not only in the respiratory system but also in various parts of the body and has a significant effect on sleep. Insomnia and poor sleep quality were observed at high rates in patients with COVID-19 as well as in the uninfected general population. Obstructive sleep apnea is also considered a risk factor in patients with severe COVID-19. Virus-induced central nervous system damage is likely to be the cause of many sleep disorders in COVID-19, but psychosocial influences also seem to have played a significant role. Sleep problems persisted at high rates for a considerable period after the infection phase was over. More attention and research on the effect of COVID-19 on sleep is needed in the future.

This study focuses on the vulnerability of our society and environment under the Covid-19 pandemic. The medical descriptions about severe acute respiratory syndrome coronavirus disease 2019 provide the serious manifestation of the SARS-CoV-2 virus and a new resilient hope of its vaccination. Moreover, with the perspective of feminist practical theology, the author explores a resilient possibility to reconstitute an ecological relationship between our society and environment. In addition, many people's depression in the time of Covid-19 is understood in the meaningful narrative of the relationship between integrity and despair to be stressed by Erikson in the perspective of Loder. Especially, this study focuses on the main stream of designing the convergence curriculum of medicine and theology to move toward the life wellbeing of community members, overcoming their difficult circumstances such as Covid-19.

A cluster of severe pneumonia of unknown etiology in Wuhan City, Hubei province in China emerged in December 2019. A novel coronavirus named severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) was isolated from lower respiratory tract sample as the causative agent. The current outbreak of infections with SARS-CoV-2 is termed coronavirus disease 2019 (COVID-19) by the World Health Organization (WHO). COVID-19 rapidly spread into at least 114 countries and killed more than 4,000 people by March 11, 2020. WHO officially declared COVID-19 a pandemic on March 11, 2020. There have been 2 novel coronavirus outbreaks in the past 2 decades. The outbreak of severe acute respiratory syndrome (SARS) in 2002-2003 caused by SARS-CoV had a case fatality rate of around 10% (8,098 confirmed cases and 774 deaths), while Middle East respiratory syndrome (MERS) caused by MERS-CoV killed 858 people out of a total 2,499 confirmed cases between 2012 and 2019. The purpose of this review is to summarize known-to-date information about SARS-CoV-2, transmission of SARS-CoV-2, and clinical features of COVID-19.

2020 was a year in which the world spent in disorder due to the pandemic of Coronavirus infection-19(COVID-19). The pandemic was at the beginning of a turning point in history. For examples, the Black Death(Pest) that destroyed the feudal system of medieval Europe in the 14th century, smallpox that led to the destruction of the Inca Empire by Spain in the 17th century, and the Spanish flu that ended World War I early. The great transformation that will come after COVID-19 is presented from various fields and perspectives, but the understanding and direction of the transformation is ambiguous. This study attempts to derive and to analyze core terms based on a network of the future of globalization after COVID-19. Four Networks related to globalization, anti-globalization, and globalization and digitalization after COVID-19 were established respectively. A network integrating four networks was also constructed. The core terms were extracted from the hub nodes, the stress centrality, and the simplified network to which the K-core algorithm was applied. After COVID-19, the changes in globalization were analyzed from the extracted core terms. This study is thought to be meaningful to propose a method of deriving and analyzing core terms based on a network in understanding social changes after COVID-19.
