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. Furthermore, better working conditions, appropriate rewards and social and mental support should be provided for nurses in emergency room.

Objectives: This study aimed to examine the relationship between COVID-19-related depressive symptoms and oral health among Korean adolescents. Methods: Data from the 17th Korea Youth Risk Behavior Web-based Survey were used and analyzed by the chi-squared test, and multiple logistic regression analysis was performed using SPSS 21.0. The final study population comprised 54,835 individuals. Results: The rates of toothache, gingival bleeding, tooth fracture, and tooth sensitivity were 21.2, 19.1, 8.7, and 30.6%, respectively. The rates of equal, increased, and decreased COVID-19-related depressive symptoms were 53.4, 36.9, and 9.7%, respectively. The rates of toothache, gingival bleeding, and tooth sensitivity were significantly higher (49.0, 48.3, and 46.3%, respectively) in the increased depressive symptom group than that in the decreased depressive symptom group (7.7, 8.1, and 7.7%, respectively). After adjusting for gender, school grade, school record, household economic status, tooth brushing frequency, smoking habit, and alcohol consumption, the risks of toothache, gingival bleeding, and tooth sensitivity in the increased depressive symptom group were symptom group were 1.64 (95% CI: 1.51-1.78), 1.55 (95% CI: 1.43-1.68), and 1.77 (95% CI: 1.65-1.89), respectively. Conclusions: There was a significant increase in oral symptoms in the group with increased depressive symptoms.

목적: 사람 코로나바이러스(human coronavirus [HCoV]) 감염은 보통 경미한 임상 양상을 보이는 경우가 많으므로, HCoV에 대한 연구가 다른 호흡기 바이러스들에 비해 상대적으로 잘 이루어지지 않고 있다. 본 연구는 국내 소아청소년에서의 HCoV 역학 및 임상적 특성을 기술하고자 하였다. 방법: 2015년 1월부터 2019년 12월까지 서울대학교 어린이병원에서 수집한 호흡기 검체의 호흡기바이러스 검사 결과를 분석하였다. 다중 reverse transcription polymerase chain reaction을 이용하여 바이러스를 검출하여 역학을 조사하였고, 이전 건강했던 어린이에게서 HCoV가 검출된 경우에 한하여 임상 진단을 분석하였다. 결과: 총 9,589 개 검체 중 5,017개(52.3%)에서 1개 이상의 호흡기바이러스가 검출되었고 463개(4.8%)가 HCoV 양성이었다(OC43 2.8%, NL63 1.4%, 229E 0.7%). 3가지 유형 모두 겨울철(11월-2월)에 유행하였으며 유형별로 역학적 차이를 보였다. HCoV-OC43이 가장 흔하였으며 매년 겨울에 유행하였다. HCoV-NL63은 1월-3월과 11월-2월 사이에 유행하였다. 한편, HCoV-229E는 2015/2016 및 2017/2018 겨울에 격년으로 유행하였다. 연령군을 0-1세, 2-4세, 5-19세로 분류하였을 때, HCoV 감염의 빈도는 2-4세에서 가장 높았고, 5-19세에서 가장 낮았다. HCoV 양성 검체의 40.8%에서 다른 호흡기바이러스가 함께 검출되었다. 리노바이러스 및 호흡기세포융합바이러스의 동시검출률이 각각 13.2%, 13.0%로 높았고, 인플루엔자 바이러스는 4.3%로 낮았다. 이전에 건강했던 135 명의 어린이에게서 가장 흔한 임상 진단은 상기도감염(60.0%)이었고, 폐렴(14.8%), 크루프(8.1%), 세기관지염(6.7%) 순이었다. 크루프는 NL63 양성인 어린이의 임상 진단 중 17.0%를 차지했다. 결론: 본 연구는 소아청소년에서의 HCoV (OC43, NL63, 229E) 감염의 역학적, 임상적 특성을 기술하였다. 소아청소년에서의 HCoV 감염에 대한 지속적인 감시가 필요하며, 추가적으로 HCoV-HKU1을 진단 패널에 포함한다면 HCoV 감염의 임상역학적 특징을 파악하는 데 더 도움이 될 것이다.

Purpose: The purpose of this study was to identify factors influencing nurses' performance of care in COVID-19 wards. Methods: The participants were 132 nurses who worked in COVID-19 wards at three hospitals, and were recruited from April 1 to May 31, 2021. Data were analyzed using descriptive statistics, t-test, ANOVA, and multiple regression analysis with SPSS/WIN 24.0 program. Results: Nursing performance was significantly and positively correlated with ethical sensitivity (r = .75, p < .001), nursing professionalism (r = .67, p < .001), and social support (r = .67, p < .001). Nursing professionalism was positively correlated with ethical sensitivity (r = .64, p < .001) and social support (r = .55, p < .001). Multiple regression analysis for nursing performance revealed that the most significant factor was ethical sensitivity (β = .47, p < .001). Ethical sensitivity, nursing professionalism, and social support explained 66.0% of total variance in nursing performance. Conclusion: Ethical sensitiviy, nursing professionalism, and social support significantly influence nurses' performace of care in COVID-19 wards. It suggests that intervention programs should be directed at improving nurses' ethical sensitivity, bolstering social support, and enhancing nursing professionalism.
