본 연구에서는 2019년에서 2021년까지, 매년 2월에서 5월 동안 대전광역시 6개 지점(기준지역 1곳 포함)의 기온 데이터를 바탕으로 COVID-19로 인한 인간 활동의 감소가 대전 지역의 도시열섬강도에 미친 영향에 대하여 분석하였다. 관측 지점에 따라 차이는 있으나 도시열섬강도는 COVID-19 전인 2019년에 비해 2020년과 2021년에 약 20% 이상 감소되었다. 인간 활동 감소는 야간의 도시열섬을 증가시키고 주간의 도시열섬을 감소시켰다. 그 결과 도시열섬강도의 일변동 폭은 지점에 관계없이 2019년에 비해 2020년 및 2021년 모두 약 20% 이상 증가하였다. 도시열섬강도 감소는 풍속과 같은 자연적 요인 및 사회적 거리두기 단계와는 큰 관련성이 없는 것으로 보인다. 반면에 COVID-19 이후 시행된 사회적 거리두기 및 확연히 감소된 대기오염물질과 관계가 있는 것으로 나타났으며, 특히 NO₂와 가장 유의미한 상관관계를 보였다.

Background: PTSD (Post-traumatic stress disorder, PTSD) had a great impact on health care workers during the COVID-19 (Corona Virus Disease 2019, COVID-19). Better knowledge of the prevalence of PTSD and its risk factors is a major public health problem. This study was conducted to assess the prevalence and important risk factors of PTSD among medical staff during the COVID-19. Methods: The databases were searched for studies published during the COVID-19, and a PRISMA (preferred reporting items for systematic review and meta-analysis) compliant systematic review (PROSPERO-CRD 42021278970) was carried out to identify articles from multiple databases reporting the prevalence of PTSD outcomes among medical staff. Proportion random effect analysis, I² statistic, quality assessment, subgroup analysis, and sensitivity analysis were carried out. Results: A total of 28 cross-sectional studies and the PTSD results of doctors and nurses were summarized from 14 and 27 studies: the prevalences were 31% (95% CI [confidence interval, CI]: 21%-40%) and 38% (95% CI: 30%-45%) in doctors and nurses, respectively. The results also showed seven risks (p < 0.05): long working hours, isolation wards, COVID-19 symptoms, nurses, women, fear of infection, and pre-existing mental illness. Two factors were of borderline significance: higher professional titles and married. Conclusion: Health care workers have a higher prevalence of PTSD during COVID-19. Health departments should provide targeted preventive measures for medical staff away from PTSD.

Background: This study aims to identify the safety and health risk perceptions toward the coronavirus disease-2019 (COVID-19) pandemic based on gender in Korean university students who work and study during the pandemic. Methods: A nationwide convenient sampling method was implemented to eliminate any regional characteristics in 757 university students, including those who studied while working. The participants answered the online questionnaire for one week. The collected data were analyzed using the R version 3.4.1 program. Results: The results comparing the safety and health risk perceptions toward COVID-19 based on the gender of the subjects who work while studying, "I often use the Internet to obtain information on COVID-19 infection control" are females appeared to use the internet more often (t = -2.18, p = 0.031) than males. "Compared to pre-COVID-19, I am currently feeling safe after the outbreak" is females felt less safe (t = 3.43, p < 0.001). Although COVID-19 infection control awareness is high among Korean university students and officials, males reported higher scores over females in all the questions, which was statistically significant. Conclusion: There should be prioritized psychological measures for prevention against COVID-19 for vulnerable groups with high mental health risks. A network must be established to protect the mental health of such groups, and candidates who require intervention must be actively identified and supported. Therefore, there must be efforts to deliver accurate information based on scientific evidence of the infectious disease, and the actions should be supported through such active communication.

본 논문에서는 학습 예측이 가능한 군집적 알고리즘으로 COVID-19에서 상황인식정보인 질병의 속성정보와 클러스터링를 이용한 군집적 알고리즘을 제안한다. 클러스터링 내에서 처리되는 군집 데이터는 신규 또는 새롭게 입력되는 정보가 상호관계를 예측하기 위해 분류 제공되는데, 이때 새롭게 입력되는 정보가 비교정보에서 오염된 정보로 처리되면 기존 분류된 군집으로부터 벗어나게 되어 군집성을 저하시키는 요인으로 작용하게 된다. 본 논문에서는 COVID-19에서의 질병속성 정보내 K-means알고리즘을 이용함에 있어 이러한 문제를 해결하기 위해 질병 상호관계 정보 추출이 가능한 사용자 군집 분석 방식을 제안하고자 한다. 제안하는 알고리즘은 자율적인 사용자 군집 특징의 상호관계를 분석학습하고 이를 통하여 사용자 질병속성간에 따른 클러스터를 구성해 사용자의 누적 정보로부터 클러스터의 중심점을 제공하게 된다. 논문에서 제안된 COVID-19의 다중질병 속성정보군집단위로 분류하고 학습하는 알고리즘은 적용한 모의실험 결과를 통해 사용자 관리 시스템의 예측정확도가 학습과정에서 향상됨을 보여주었다.

COVID-19, a highly infectious disease, has affected the globe tremendously since its outbreak during late 2019 in Wuhan, China. In order to respond to the pandemic, governments around the world introduced a variety of public health measures including contact-tracing, a method to identify individuals who may have come into contact with a confirmed COVID-19 patient, which usually leads to quarantine of certain individuals. Like many other governments, the South Korean health authorities adopted public health measures using latest data technologies. Key data technology-based quarantine measures include:(1) Electronic Entry Log; (2) Self-check App; and (3) COVID-19 Wristband, and heavily relied on individual's personal information for contact-tracing and self-isolation. In fact, during the early stages of the pandemic, South Korea's strategy proved to be highly effective in containing the spread of coronavirus while other countries suffered significantly from the surge of COVID-19 patients. However, while the South Korean COVID-19 policy was hailed as a success, it must be noted that the government achieved this by collecting and processing a wide range of personal information. In collecting and processing personal information, the data minimum principle - one of the widely recognized common data principles between different data protection laws - should be applied. Public health measures have no exceptions, and it is even more crucial when government activities are involved. In this study, we provide an analysis of how the governments around the world reacted to the COVID-19 pandemic and evaluate whether the South Korean government's digital quarantine measures ensured the protection of its citizen's right to privacy.

Objectives : To analyze symptoms of olfactory dysfunction caused by COVID-19 from a Korean Medical Perspective. Methods : Previous studies dealing with olfactory dysfunction accompanying COVID-19 were studied and analyzed for general characterization. Physiology and pathology of olfactory functions within the classical texts of Korean Medicine were collected and analyzed, through which symptoms of olfactory dysfunction in COVID-19 were examined. Results : Olfactory dysfunction manifested in high ratios in the early stages of confirmed COVID-19 cases, at times independent of other nasal symptoms such as blockage or discharge. There was a high chance of loss of taste being accompanied, while mental problems such as a tendency to have difficulty concentrating were present as well. In most cases, recovery took one to two weeks. From a Korean Medical perspective, physiology of olfactory function is closely linked to the Lungs, Ancetral Qi[宗氣], and the Heart, while its dysfunction could be explained by pathological factors such as Wind-Cold, Fire stagnation, Qi deficiency, Wind stroke, etc. Conclusions : In the context of external contraction disease[外感病], olfactory dysfunction could be caused by problems in the Lungs and Stomach that are responsible for breathing, or the Heart which is involved in recognizing and differentiating scent. General characteristics of COVID-19 imply it to be closely related to the Heart. In clinical application, overall symptoms need to be considered in diagnosis and treatment planning, after which further approaches could made to determine the problem to be of the Lung and Stomach, or of the Heart.
