This study was conducted to identify the subjective damage caused by COVID-19 and its related factors. The study subjects were members of the Korean Dental Association (KDA). We investigated the damage to dental clinics and hospitals caused by COVID-19 between January and April 2020. After analyzing the final 3,189 responses, the rate of decrease in patients was the highest at 34.9% in March, and the rate of decrease in income was the highest at 34.0% in April. As a result of the multilevel analysis, the damage caused by COVID-19 was greater in regions with more confirmed patients, more careers, and fewer dental staff. The government should establish a compensation plan for hospitals and clinics to prevent the collapse of the medical system due to the prolonged COVID-19. In addition, support for dentistry should be provided to maintain the oral health care system in the future.

The causes of climate change are natural and artificial. Natural causes include changes in temperature and sunspot activities caused by changes in solar radiation due to large-scale volcanic activities, while artificial causes include increased greenhouse gas concentrations and land use changes. Studies have shown that excessive carbon use among artificial causes has accelerated global warming. Climate change is rapidly under way because of this. Due to climate change, the frequency and cycle of infectious disease viruses are greater and faster than before. Currently, the world is suffering greatly from coronavirus infection-19 (COVID-19). Korea is no exception. The first confirmed case occurred on January 20, 2020, and the number of infected people has steadily increased due to several waves since then, and many confirmed cases are occurring in 2021. In this study, we conduct a study on climate change before and after COVID-19 using weather data from Korea to determine whether climate change affects infectious disease viruses through logistic regression analysis. Based on this, we want to classify before and after COVID-19 through a logistic regression model to see how much classification rate we have. In addition, we compare monthly classification rates to see if there are seasonal classification differences.

Purpose: The purpose of this study was to explore emergency room nurse's work experiences during the COVID-19 pandemic. Methods: Data were collected from 15 registered nurses working in the emergency room between October, 10th and December 15th, 2020, through focus group interviews and in depth interviews. Collected data were analyzed using Colaizzi's phenomenological method. Results: The study derived four categories and eight themes. The four categories are 'sense of cringing with fear', 'nursing in chaotic situation', 'lonely struggles', and 'career growth as a nurse'. Emergency room nurses experienced fear and confusion in the COVID-19 pandemic, but overcame the crisis and had positive experiences of professional growth as a nurse. Conclusion: To protect emergency room nurses from infectious disease and improve their professional quality of life during the COVID-19 pandemic appropriate education and healthcare resource should be provided. It is necessary to reflect clinical worker's opinions and improve the delivery system of guideline to reduce confusion in the field and develop practical infectious disease control guideline.

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.

This study aimed at examining fashion consumers' awareness during the COVID-19 pandemic. Big data analysis methods, such as text mining, social network analysis, and regression analysis, were applied to user posts about fashion on Korean portal websites and social media during COVID-19. R 3.4.4, UCINET 6, and SPSS 25.0 software were used to analyze the data. The results were as follows. In researching the popular fashion-related topics during COVID-19, the prevention of infection and prophylaxis were significant concerns in the early stage (Jan 1 to Jan 31, 2020), and changed to online channels and online fashion platforms. Then, various topics and fashion keywords appeared with COVID-19-related keywords afterwards. Fashion-related subjects concerned prophylaxis, home life, digital and beauty products, online channels, and fashion consumption. In comparing fashion consumers' awareness during COVID-19 with SARS and MERS, "face masks" was the common keyword for all three illnesses; yet, the prevention of infection was a major consumer concern in fashion-related subjects during COVD-19 only. As COVD-19 cases increased, the search volume for face masks, shoes, and home clothes also increased. Consumer awareness about face masks shifted from blocking yellow dust and micro-dust to the sociocultural significance and short supply. Keywords related to performance turned out to be the major awareness as to shoes, and home clothes were repurposed with an expanded range of use.

The aim of this study was to investigate the level of dental infection control experienced by dental hygiene students in clinical practice institutions to identify problems and improve infection control in dental institutions. This study conducted online surveys targeting 269 dental hygiene students from universities that conducted clinical practice to determine the students' level of awareness regarding dental infection control in dental institutions and the reality of infection control in dental institutions. The results showed that dental hygiene students recognized the need for infection control and education about infection control at a high level. However, only 47% of the students were accurately informed about COVID-19. Basic instruments, periodontal instruments, and implant surgical instruments were sterilized after use for each patient, mostly by the institution, but 3-way syringe tips, preservation instruments and prosthetic instruments were more frequently reused without sterilization immediately after use. For dental infection control to be practiced at dental institutions, it is necessary to establish a systematic and safe infection control system, including infection control education, designation of infection managers, and provision of infection control guidelines.

Purpose: This study aimed to develop a nursing simulation learning module for coronavirus disease 2019 (COVID-19) patient-care and examine its effects on clinical reasoning competence, clinical competence, performance confidence, and anxiety in COVID-19 patient care for nursing students. Methods: A non-equivalent control group pre- and post-test design was employed. The study participants included 47 nursing students (23 in the experimental group and 24 in the control group) from G City. A simulation learning module for COVID-19 patient-care was developed based on the Jeffries simulation model. The module consisted of a briefing, simulation practice, and debriefing. The effects of the simulation module were measured using clinical reasoning competence, clinical competence, performance confidence, and anxiety in COVID-19 patient-care. Data were analyzed using χ²-test, Fisher's exact test, t-test, Wilcoxon signed-rank test, and Mann-Whitney U test. Results: The levels of clinical reasoning competence, clinical competence, and performance confidence of the experimental group were significantly higher than that of the control group, and the level of anxiety was significantly low after simulation learning. Conclusion: The nursing simulation learning module for COVID-19 patient-care is more effective than the traditional method in terms of improving students' clinical reasoning competence, clinical competence, and performance confidence, and reducing their anxiety. The module is expected to be useful for educational and clinical environments as an effective teaching and learning strategy to empower nursing competency and contribute to nursing education and clinical changes.

Purpose: This study attempted to present a strategy to increase behavioral vaccination intention by identifying factors affecting parents' intention to have their children vaccinated against coronavirus disease 2019 (COVID-19) by applying the modified theory of planned behavior. Methods: An online survey was conducted with 146 parents of children aged 5 to 17 from August 1 to 30, 2022, and, as a result, 146 data were analyzed. The moderating effect of perceived behavioral control in the relationship between parents' attitude, subjective norms, and behavioral intention for children's COVID-19 vaccination was analyzed using the Process Macro (10,000 bootstrapping, 95% confidence interval), and a simple slope analysis was performed to identify differences by group. Results: The moderating effect of perceived behavioral control was statistically significant in the relationship between parent's attitude and subjective norms for COVID-19 vaccination and behavioral intention. In the simple slope analysis, the reinforcement effect was greatest when the level of perceived behavioral control was high. Conclusion: Since vaccination is most likely when recommended by healthcare providers, it is necessary to ensure that health education through community health experts or mass media can be effectively conducted. In particular, objective information on the effectiveness and safety of COVID-19 vaccinations for children, including monitoring of potential side-effects, should be actively reported.

The purpose of this study is a method to discover problems and improve them by analyzing the status of software education of A primary school conducted by online class. The coronavirus infection-19(COVID-19) pandemic, which began in early 2020, has continued to delay the start of the new semester. Finally, on April 9, 2020, the first semester began with online class. While progressing non-face to face online class, most students said they had difficulties. Students solved difficulties in class with Internet searches or program hints, not teachers. In the post-class self-evaluation, most students answered that there was no increase in coding skills. To solve this problem, the school rents additional smart devices to student. schools should have real-time interactive classes. After covid 19, online class became a paradigm for classes. Therefore, software education will also require research and development of curriculum and teaching learning methods suitable for online classes.
