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.

본고는 코로나19라는 글로벌 팬데믹 상황에서 감염병 역학모형에 관한 내용과 기초재생산수, 집단면역임계, 백신비축 등의 주요 개념을 개론 수준에서 다루었다. 국내 첫 감염자 발생 이후 4월 12일까지의 데이터를 기준으로 분석해 볼 때 한국의 기초재생산수는 약 2의 값을 가지는데 이는 코로나19가 발생한 다른 나라에 비해 현저히 낮은 수치로 평가된다. 만일에 코로나19 백신이 개발되는 것을 가정하여 이의 비축규모를 추정해보면 인구의 최소 62%에 공급할 수 있는 수준이어야 하는 것으로 나타났다. 한편, 한국의 코로나19의 성공적 대응에는 사회적 거리두기 정책이 주된 요인 중의 하나라는 점도 발견하였다. 그러나 5월 이후 사회적 거리두기에 대한 다소 느슨해진 경향이 없지 않은데, 지역감염의 확산을 위해서는 원론적으로 대응할 필요가 있다. 본고는 학술적 관점이 아닌, 방역의 실무적 차원에서 역학모형, 그리고 경제-역학 모형을 활용하는 방법을 소개한 것 뿐이다. 보다 정교한 역학 모형을 제대로 연구하기 위해서는 상당한 규모의 팀워크가 필요하다. 2015년 메르스 이후 역학조사를 위한 자원이 보강되었다 하지만, 앞으로 역학조사 인력, 데이터 시스템 구축, 그리고 보건·경제·통계·수학 분야 등의 연구진이 보강되어야 할 것이다.

The purpose of this study was to investigate of resilience on nursing students in COVID-19 pandemic situation. Data were collected from 320 nursing students in B city and analyzed by t-test, ANOVA, Pearson correlation coefficient, and multiple regression using SPSS/WIN 22.0. The degree of resilience in nursing students was 3.78±0.61. There were significant differences in college life adaptation with department (F=9.932, p<.001), number of friend (F=5.681, p<.001), close professor (t=3.739, p<.001), There was positive correlation between resilience and grit (r=.469, p<.001), nursing professionalism (r=.614, p<.001), nurses' image (r=.552, p<.001). The factors affecting resilience of the study subjects were grit (β=.321, p<.001), nursing professionalism (β=.385, p<.001), nurses' image (β=.165, p=.022), with an explanatory power of 47.3%. Through the results of this study, it was confirmed that it is necessary to improve grit, nursing professionalism, and nurses' image in order to improve the resilience of nursing students in the COVID-19 pandemic.

2019년 12월 중국에서 최초 보고된 이후 COVID-19 전염병은 전 세계에 대유행(팬데믹)을 확산하면서 역사적인 변화를 일으키고 있다. 경제, 사회 전반에 코로나 전과 코로나 후에 대한 새로운 규범과 질서를 강요하고 있다. 이에 본 고는 코로나19에 대한 이해와 그 영향 및 파급효과와 이를 대처하기 위한 세계 각국의 정책 현황을 살펴보았다. 특히, 치료제와 백신 등 과학적 해결을 위해 치열한 경쟁을 펼치고 있는 연구개발 현황을 고찰함으로써 한국의 관련 과학기술 정책과 연구개발의 방향을 모색하고자 하였다. 코로나19가 몰고 온 커다란 글로벌 위기를 통해 세계 질서가 재편될 가능성이 높아지고 있다. 현재까지 한국은 K-방역을 통해 모범적 방향을 제시하고 있다. 이는 과학기술과 연구개발 및 관련 정책들이 적절하게 역할을 한 결과로 평가된다. 본 고에서 고찰된 내용은 이러한 긍정적 효과를 지속적으로 유지하고 제고하는데 도움이 되고자 하는 것이다.

코로나바이러스감염증-19로 인한 팬데믹 상황이 지속되면서 감염증 정보의 불확실성으로 인해 코로나 관련 루머가 온라인상에서 빠르게 전파되고 있다. 이러한 코로나 관련 가짜 뉴스를 사전에 탐지하기 위해, 본 연구에서는 한국어 코로나 가짜 뉴스 데이터셋을 구축하고, 개체명과 사용자 재확산 정보를 이용한 한국어 가짜 뉴스 탐지 모델을 제안한다. 가짜 뉴스 팩트체킹 언론인 서울대팩트체크센터에서 코로나 관련 루머 및 가짜 뉴스에 대한 검증 기사를 수집한 후, 기사로부터 개체명 추출 모델을 통해 주제 키워드를 추출하고, 이를 이용해 유튜브 상의 사용자 재확산 정보를 수집하여 데이터셋을 구성하였다. BERT 기반의 제안 모델을 다양한 비교군과 비교하였고, 특성 조합에 따른 실험을 통해 각 특성 정보(기사 텍스트, 개체명 데이터, 유튜브 데이터)가 가짜 뉴스 탐지 성능에 미치는 영향을 알아보았다.

The COVID-19 pandemic has brought about significant social changes through government prevention and control measures, changes in people's risk perceptions, and lifestyle changes. In response, urban inhabitants changed their behaviors significantly, including their preferences for transportation modes and urban spaces in response to government quarantine policies and concerns over the potential risk of infection in urban spaces. These changes may have long-lasting effects on urban spaces beyond the COVID-19 pandemic or they may evolve and develop new forms. Therefore, this study aims to explore the potential for urban spaces to adapt to the present and future pandemics by examining changes in urban residents' preferences in travel modes and urban space use due to the COVID-19 pandemic. This study found that overall preferences for travel modes and urban spaces significantly differ between the pre-pandemic, pandemic, and post-pandemic periods. During the pandemic, preferences for travel modes and urban spaces has decreased, except for privately owned vehicles and green spaces, which are perceived to be safe from transmission, show more favorable than others. Post-pandemic preferences for travel modes and urban spaces are less favorable than pre-pandemic with urban spaces being five times less favorable than transportation. Although green spaces and medical facilities that were positively perceived during the pandemic are expected to return to the pre-pandemic preference level, other factors of urban spaces are facing a new-normal. The findings suggest that the COVID-19 pandemic has had a significant impact on urban residents' preferences for travel modes and urban space use. Understanding these changes is crucial for developing strategies to adapt to present and future pandemics and improve urban resilience.

With the global pandemic of COVID-19, it is pointed out that exposure to false information to the public could cause serious problems. However, in pandemic situations, there is also an positive effect for the public to share private-led information rather than centralized unilateral delivery of information. This study analyzes the role of private-led information provision in infectious disease situations. To this end, topic modeling and sentiment analysis is carried out on online reviews of all COVID-19-related applications in Google Playstore provided by the Korean government and the private. The results showed that the user's evaluation of private apps, which were used from the early stage of COVID-19, was much higher than the apps provided by the government. In particular, users responded more positively to private apps than government apps in all aspects such as reliability of information, risk avoidance, timeliness, usefulness, and stability. Based on these results, a post-monitoring system is recommended rather than a pre-block of all private apps.

As can be seen from the statement by the UN Secretary-General that "COVID-19 is a crisis with a woman's face," women have experienced great crisis, pain, and difficulties caused by the COVID-19 pandemic. This study examined the situations of women through statistical data and research studies. Through this study, economic, socio-cultural, and psycho-emotional aspects were dealt with in detail, and how these issues appeared in relation to "caring" were examined. In addition, as a response of the church to these problems and crises, pastoral theological reflection was promoted through "Ethics of Care" and "caring ministry". The "caring ministry" of the church extends not only to personal care within the church, but also to social, cultural, economic, political, and ecological issues, and the church has a missionary mission to respond to these issues related to disasters with a public nature. Furthermore, through educational ministry, the change of values and mindsets on "care" and inequality and Diakonia, the loving care of the church community, should be encouraged.

Due to the COVID-19 pandemic, the global population has experienced drastic changes, one of which is the increase in remote work. Given the ongoing possibility of exposure to infectious diseases and various other circumstances, the expansion of remote work is anticipated. To enhance the efficiency of remote work and address its existing limitations, this study surveyed the perceptions of indoor environments among individuals who worked from home during the COVID-19 pandemic. The study examined how the characteristics of individuals influenced their perceptions of indoor environments. It was found that the number of occupants and rooms, size of the house, and noise sensitivity affected the perceptions of outdoor noise, neighbor noise, and indoor noise caused by cohabitants. The findings can be used as foundational data for designing multipurpose housing that can be utilized not only for residential purposes but also for work and educational settings in the future.
