본 논문의 목적은 COVID-19의 최근 주요 연구 동향을 파악하는데 있다. 이에 Elsevier에서 제공하는 해외 학술 DB인 SCOPUS를 활용하여 최근 3년간(2020~2022) COVID-19의 연구 동향을 파악하고자 한다. 빈도 분석 결과, covid가 7,248건, pandemic이 4,974건, study가 3,313건, research가 2,137건, crisis가 1,777건 순으로 그 중요도가 나타났다. 트렌드 분석결과, covid와 pandemic은 꾸준하게 연구가 진행되고 있으나, study, research, crisis는 최근 들어 연구가 다소 감소하고 있는 것으로 나타났다. LDA 토픽 모델링 분석 결과, 중요한 토픽은 'covid19, pandemic' 인 것으로 나타났다. 이는 COVID-19에 대한 연구가 일상생활뿐만이 아니라 기업이나 조직에서도 필요하기 때문에 의학 이외의 다른 학문 분야에서도 중요하다는 것을 보여준다. 특히 COVID-19가 그 어느 때보다도 중요해지는 상황에서 COVID-19의 연구가 미치는 영향 및 파급효과에 관한 관심이 지속적으로 이루어질 것으로 보인다.

The objective of the study is to investigate the impact of the COVID-19 pandemic on Saudi Arabia stock market. The study relied on the data of the daily closing stock market price index Tadawul All Share Index (TASI), and the number of daily cases infected with COVID-19 during the period from March 15, 2020, to August 10, 2020. The study employs the Vector Auto-Regressive (VAR) model, the Impulse Response Function (IRF) and Autoregressive Conditional Heteroscedasticity (ARCH) models. The results of the correlation matrix and the Impulse Response Function (IRF) show that stock market returns responded negatively to the growth in COVID-19 infected cases during the pandemic. The results of ARCH model confirmed the negative impact of COVID-19 pandemic on KSA stock market returns. The results also showed that the negative market reaction was strong during the early days of the COVID-19 pandemic. The study concluded that stock market in KSA responded quickly to the COVID-19 pandemic; the response varies over time according to the stage of the pandemic. However, the Saudi government's response time and size of the stimulus package have played an important role in alleviating the impacts of the COVID-19 pandemic on Saudi Arabia Stock Market.

The purpose of the research is to examine whether government regulation on Covid 19 pandemic has had a significant impact in economic sectors, particularly on consumer behavior. Thus there are three hypotheses, 1) viral marketing has an effect on online trust during the Covid-19 Pandemic Era, 2) viral marketing has an effect on impulse buying during the Covid-19 Pandemic Era, and 3) Viral marketing has an effect on impulse buying in the Covid-19 Pandemic Era through online trust. To test the hypotheses, questionnaires were distributed to 150 respondents, however, only 110 were selected due to incomplete data. There are 3 variables, namely viral marketing, online trust, and impulse buying, where online trust is also a mediating variable. Once the assumption test is completed, the researcher employs path analysis to test the hypotheses. The results are 1) there is an effect of viral marketing on online trust in the Covid-19 Pandemic Era, 2) There is no effect of viral marketing on impulse buying in the Covid-19 Pandemic Era, and 3) Viral marketing has an effect on impulse buying in the Covid-19 Pandemic Era through online trust. This means online trust succeed in mediating viral marketing-impulse buying relationship. The findings emphasized that the credibility of online trust enforce consumers in making buying decisions.

This study explores the impact of the COVID-19 pandemic on the stock prices of state-owned enterprises listed on the Indonesia Stock exchange. The impact of the pandemic is analyzed based on different pandemic phases and the corresponding government pandemic interventions to curb the disease. This study analyzes 6 pandemic event dates, covering the time period from January 2020 to February 2021. A total of 20 state-owned enterprises are included as the sample of this study. Test of difference is employed to compare the stock prices of the state-owned enterprises before and after each pandemic event date. In general, this study confirms the adverse impact of the COVID-19 pandemic on the stock prices, especially the event in 2020, although some variations do exist. The results of the study reveal a significant decrease in the stock prices of the state-owned enterprises after the announcement of the first confirmed COVID-19 cases, the announcement of COVID-19 as a global pandemic, the imposing of Large Scale Social Restriction (PSBB I and PSBB II). In contrast, the stock prices increase after the imposing of a new normal policy and the imposing of Public Activity Restriction (PPKM). This study also documents that the effect of the pandemic may vary based on the pandemic phase.

The spread of Omicron, a mutated version of COVID-19 across several countries is leading to the discussion of lockdown once again for curbing the spread of the new virus. In this context, this research is showing the impact of lockdown for the successful control of the COVID-19 pandemic in Saudi Arabia. The outbreak of the COVID-19 pandemic around the globe has affected Saudi Arabia with around 2,37,803 confirmed cases within the initial 4 months of transmission. Saudi Arabia has announced a 21-day lockdown from March 23, 2020, to reduce the transmission of the COVID-19 pandemic. Machine Learning-based, Multinomial logistic regression was applied to understand the relationship between daily COVID-19 confirmed cases and lockdown in the 17 most-affected cities of KSA. We used secondary published data from the Ministry of Health, KSA daily dataset of COVID-19 confirmed case counts. These 17 cities were categorized into 4 classes based on lockdown dates. A total of three scenarios such as night lockdown, full lockdown, and no lockdown have been analyzed with the total number of confirmed cases with 4 classes. 15 out of 17 cities have shown a strong correlation with a confidence interval of 95%. These findings provide evidence that the COVID-19 pandemic may be partially suppressed with lockdown measures.

Purpose: This study investigated the differences between patients with acute carbon monoxide (CO) poisoning who visited the emergency department (ED) before and during the coronavirus disease 2019 (COVID-19) pandemic. Methods: This was a single-center retrospective observational study. Patients with CO poisoning who visited the ED during the period from February 2020 to January 2023 were classified as the COVID-19 pandemic group, and those from February 2019 to January 2020 were classified as the non-pandemic group. Patients' medical records were reviewed, their demographic and clinical characteristics were compared, and the length of stay in ED was checked. The time from admission to the ED to the start of hyperbaric oxygenation (HBO) was defined as the door-to-HBO time, and this parameter was compared between both groups. Results: In total, 672 patients were included in this study. The proportion of intentional poisoning was significantly higher in the COVID-19 pandemic group than in the non-pandemic group (p=0.028). The proportion of intentional poisoning significantly increased in the 20- to 29-year-old age group during the COVID-19 pandemic (p<0.001). In addition, it took longer to initiate HBO in the COVID-19 pandemic group than in the non-pandemic group (p=0.001). Conclusion: These findings suggest that pandemics of infectious diseases, such as COVID-19, increase the proportion of intentional CO poisoning, and it may take longer to initiate HBO after visiting the ED. Efforts will be needed to decrease intentional CO poisoning and length of stay in ED.
