Coronavirus disease 19 (COVID-19) is caused by SARS-CoV-2 (Severe Acute Respiratory SyndromeCoronavirus 2). To date, seven coronaviruses that can infect humans were reported. Among them, infections with four coronavirus strains (HCoV-229E, HCoV-OC43, HCoV-NL63, and HCoV-HKU1) resulted in mild symptoms such as common cold, whereas SARS-CoV and MERS-CoV caused severe symptoms and epidemics in 2002 and 2012, respectively. In the most recent, SARS-CoV-2 was first reported in Wuhan, China in December 2019 and became a notorious cause of the ongoing global pandemics. To diagnose, treat, and prevent COVID-19, the development of rapid and accurate diagnostic tools, specific therapeutic drugs, and safe vaccines essentially are required. In order to develop these powerful tools, it is prerequisite to understand a phenotype, a genotype, and life cycle of SARS-CoV-2. Diagnostic techniques have been developing rapidly around world and many countries take the fast track system to accelerate approval. Approved diagnostic devices are rapidly growing facing to urgent demand to identify carriers. Currently developed commercial diagnostic devices are divided into mainly two categories: molecular assay and serological & immunological assay. Molecular assays begins the reverse transcription step following polymerase chain reaction or isothermal amplification. Immunological assay targets SARS-CoV-2 antigen or anti-SARS-CoV-2 antibody of samples. In this review, we summarize the phenotype, genome structure and gene expression of SARS-CoV-2 and provide the knowledge on various diagnostic techniques for SARS-CoV-2.

Purpose: This study aimed to understand nurses' lived experiences of caring for patients with COVID-19. Methods: The phenomenological research method was used. The study participants were 16 Korean nurses who had experiences in caring for patients with COVID-19 in clinical settings. Data was collected using one-on-one in-depth interviews, from June 30 to September 30, 2020. During the interview, the quarantine rules were observed. Results: The study derived four themes clusters and thirty-eight sub themes. Four theme clusters were identified, i.e., 'a repetitive sense of crisis', 'enduring a drastic change,' 'sacrifice of personal life,' and 'pride in nursing'. The nurses' experiences of caring for patients with COVID-19 were an uneasy, unfamiliar, and threatening experiences for an individual, but it is an opportunity for a nursing organization to renew. Accordingly, it was found that nurses faithfully fulfill their individual roles with a vocation and responsibility. Conclusion: The study provides an in-depth understanding of the situational, psychological, and environmental aspects of challenges facing nurses in the pandemic situation. Based on the findings, institutional follow-up measures should be provided to establish support systems for better nursing care. In addition, studies are needed to track nurses' experiences in the prolonged COVID-19 situation.

We analyzed efficiency and productivity of the Indian non-life insurance market affected by the COVID-19 pandemic from 2020. Using data envelopment analysis(DEA), we examined non-life insurance companies selling health insurance products in India from FY2013 to FY2019. We found the followings. First, average efficiency of the entire non-life insurance industry worsened in the beginning yet improved later. Second, analyzing the efficiency measures by group, we found that private insurance companies had the highest efficiency, followed by state-run insurance companies and pure health insurance companies. Third, average annual productivity growth rate of companies operating distance selling channels including telemarketing is higher than that of traditional face-to-face channels. During and after the COVID-19 pandemic, therefore, Indian non-life insurance companies should focus their resources and efforts on the development of distance selling channels when establishing business strategies. Besides, it would be interesting to extend our analysis to the post-coronavirus period and we leave this for future research.

Due to the global pandemic caused by COVID-19 in 2020, there have been major changes in the education sites. Universities have fully introduced remote learning, which was considered as an auxiliary education, and non-face-to-face classes have become commonplace, and professors and students are making great efforts to adapt to the new educational environment. In order to improve the quality of non-face-to-face lectures amid these changes, it is necessary to study the factors affecting lecture satisfaction. Therefore, This paper presents a new methodology using big data to identify the factors affecting university lecture satisfaction changed before and after COVID-19. We use Topic Modeling method to analyze lecture reviews before and after COVID-19, and identify factors affecting lecture satisfaction. Through this, we suggest the direction for university education to move forward. In addition, we can identify the factors of satisfaction and dissatisfaction of lectures from multiangle by establishing a topic classification model with an F1-score of 0.84 based on KoBERT, a deep learning language model, and further contribute to continuous qualitative improvement of lecture satisfaction.

This study conducted a questionnaire survey using the Google questionnaire on 285 college students over 20 years old who attended universities in Chungnam to investigate the personal quarantine attitude of college students according to COVID-19. As a result, the attitude of washing hands, coughing etiquette, wearing a mask, and keeping distance under running water for more than 30 seconds scored high. However, when the mask was removed, the method of storing the mask or disinfecting surrounding objects such as desks at school was insufficient. Therefore, the attitude of personal quarantine should be more emphasized in the national quarantine system as a basic policy for preventing the spread of COVID-19 in the future and ending the virus.

This study discussed its implications for the meaning in life, which began to emerge through existential psychotherapy in the era of coronavirus infection 19 (COVID-19). In the midst of the COVID-19 pandemic, we are making efforts to live a meaningful life, and individuals and communities are making efforts to find meaning in how to live a meaningful life. Humanity has a premise for a peaceful life, and since the past, interest in the meaning in life has continued. The deadly virus called COVID-19, which hit the world in December 2019, created stress such as anxiety, alienation, and depression in people, endangering the lives of individuals and communities. Research on the meaning in life was active even before COVID-19, but I think it is necessary to look at the changes in people's meaning in life and how COVID-19 is affecting each individual amid the global pandemic of the virus. In other words, clarifying the meaning of our lives in the era of COVID-19 is a coping to reduce stress and a catalyst to improve the quality of life. This study aims to provide basic research to prepare ways to improve the quality of life in the era of COVID-19 by examining various perspectives and results on the meaning in life.

Objectives: The objectives of this study were to verify the level of ethical consciousness and decision-making of dental hygiene students in pandemic as coronavirus disease 2019 (COVID-19). Methods: This study included 249 college students who were interested in new infectious diseases. They completed a questionnaire on a 5-point scale, and data were analyzed by independent t-test, ANOVA, and correlation. Results: The perception of COVID-19 was moderate at 3.42 points. This was higher among males, first graders, emergency management students, those who received education and experienced self-quarantine. The level of ethical consciousness was moderate (3.89 points), which was higher in sophomores, emergency management students. Ethical decision-making was moderate, with a score of 3.44, and was higher in those with first grade, field practice training, and self-quarantine experience. The level of perception positively correlated with ethical consciousness (α=0.310, p<0.01). In addition, as the degree of ethical consciousness increased, the degree of decision-making also increased (α=0.539, p<0.01). Conclusions: In a crisis, involving the spread of COVID-19, providing prospective dental hygienists accurate information and an experience similar to that faced by patient is necessary for raising the level of ethical consciousness and decision-making.

Corona 19 quarantine is often not implemented at degraded bus stops. We conducted this study to improve these problems. The inside and outside of the shelter can be sterilized with UV photocatalyst coating to maintain a hygienic and clean shelter, and passengers can breathe smoothly by reducing carbon dioxide in the shelter using CO₂ sensors and fans. It is also expected that the body temperature can be measured using a body temperature sensor to prevent more than 20% of the spread of the coronavirus in the shelter by isolating suspected coronavirus patients in the first place. When the temperature measurement distance was less than 10cm, the accuracy of the temperature measurement was 98.9%. You can communicate your intention to ride safely and clearly without contacting the bus driver by using a ride bell that uses wireless communication inside the shelter.

In 2020, the novel coronavirus disease (COVID-19) struck the world. This study examined Korean public libraries' responses during the COVID-19 pandemic to determine their working practices, service patterns, applied strategies, and roles played. The study administered an online survey to 317 public librarians in South Korea. The results indicated that librarians reported significant transitions regarding the services provided. However, only 15.5% of the survey respondents reported that they had experienced trainings/workshops for library staff members. Survey participants also identified challenges such as the limitations of non-face-to-face services, complaints from library patrons, and overwork due to epidemic prevention. When it comes to the expected roles of public libraries in upcoming disasters, the study contends that information providers, who guide the public through various information resources, would play the most critical role. An analysis of a few open-ended questions' answers proliferated the highlighted findings. Based on the key findings, this paper also discussed implications for information professionals and future research.
