최근 중국으로 인해 코로나 19 바이러스가 전 세계로 퍼지면서 각 나라에 큰 위협이 되고 있다. 이에 대한민국의 국민들은 매일 코로나 바이러스 확진자와 사망자, 그리고 대처방안에 대한 브리핑을 정부 관계자로부터 듣고 이를 시행하고 있다. 본 논문에서는 코로나바이러스에 대해 브리핑을 하는 정부 관계자의 음성이 어떤 특정이 있는가를 규명해 보고자한다.

This study examined the meaning of the experiences of university students majoring in occupational therapy, where their practice was discontinued due to COVID-19, and to provide basic data for future measures. This study was a phenomenological study. The subjects of this study were seven students. Interviews were analyzed according to Colaizzi data analysis. As a result of an interview, it was organized into 17 themes, six themes clusters, and two categories. The themes clusters were indifference, problem recognition, wandering, coping, aftermath, and anticipation for coping. The students experienced a confused and frustrating situation after recognizing the problem of COVID-19 and experienced anxiety and regret as they experienced the interruption of their fieldwork. The students expected all universities to implement a batch and quick response at the same time. In the future, a systematic communication and delivery system is needed to quickly prepare and implement countermeasures at the same time as institutions, associations, and universities.

코로나바이러스는(COVID-19)는 2019년 12일 중국 후베이성 우한시에서 시작된 코로나바이러스감염증으로 2020년 1월부터 전 세계로 퍼져, 일부 국가 및 지역을 제외한 대부분의 나라와 모든 대륙으로 확산되었다. 이에 WHO는 범 유행전염병(Pandemic)을 선언하였다. 2022년 3월 18일 현재 국내 누적 확진환자 8,657,609명과 11,782명의 사망자를 일으켰고 전 세계적으로도 많은 사상자를 내고 있는 실정이고 사회 및 경제적인 피해로도 계속 확대되고 있다. 많은 감염자와 사망자의수에 대한 예측은 코로나바이러스의 전염병을 예방하고 즉각적 조치를 취할 수 있는데 도움이 될 수 있다. 본 연구에서는 문화적 인자를 제외한 국내에서 연구 사례가 많지 않은 기상 요인을 인자로 포함하여 머신러닝 모델을 통해 확진자를 예측하였다. 그리고 여러 가지 모델을 성능 평가 기법인 Root Mean Square Error(RMSE) 및 Mean Absolute Percentage Error(MAPE)를 통해 성능을 평가하고 비교하여 정확도 높은 모델을 제시하였다.

신종 코로나바이러스 감염증(Coronavirus disease 2019; COVID-19)이 빠르게 확산됨에 따라 세계적인 전염병 대유행인 팬데믹(Pandemic)으로 선언되었다. 감염자들은 꾸준히 증가하고 있고 최근에는, 무증상 감염자들이 나타나고 있어 의심 환자를 조기에 판단하고 선별할 수 있는 기술이 필요하다. 본 논문에서는 흉부 방사선 검사(chest Radiography; CXR) 영상을 딥러닝(Deep Learning)하여 정상인, 폐렴 환자, 코로나바이러스 감염자를 분류할 수 있도록 한다.

코로나바이러스감염증-19(COVID-19)의 확산 추세로 한국뿐만 아닌 전 세계적으로 여행 횟수의 빈도가 낮아짐에 따라 각 지역의 소상공인들은 매출의 큰 타격을 입었다. 본 연구에서는 사용자들의 여행 경험을 기록하고 공유하는 시스템을 개발하였다. 코로나바이러스감염증-19(COVID-19)의 종식 이후 다양한 사용자들의 여행 경험을 공유하고 이를 바탕으로 여행지를 추천하고 정보를 공유하여 지역 경제의 활성화를 이끌어 낼 수 있을 것으로 기대된다.

Purpose: A change is expected in the pattern of respiratory viruses including human coronavirus (HCoV) after the coronavirus disease 2019 (COVID-19) outbreak. Accordingly, identifying the distribution of respiratory viruses before the COVID-19 outbreak is necessary. Methods: We retrospectively analyzed the results of samples of nasal swabs collected from children under aged ≤18 years who were hospitalized at Myongji Hospital, Gyeonggi-do due to acute respiratory infections from 2017 to 2019. Viruses were detected by real-time reverse transcription polymerase chain reaction (RT-PCR). Results: Out of 3,557 total patients, 3,686 viruses were detected with RT-PCR including coinfections. Of the 3,557 patients, 2,797 (78.6%) were confirmed as PCR-positive. Adenovirus and human rhinovirus (hRV) were detected throughout the year, and human enterovirus was most detected during summer. Respiratory syncytial virus, influenza virus, and HCoV were prevalent in winter. In patients with croup, parainfluenza virus was most frequently detected, followed by hRV and HCoV. The PCR positive rate in summer and winter differed significantly. Conclusions: Respiratory virus patterns in northwestern Gyeonggi-do were not much different from previously reported data. The data reported herein regarding respiratory virus epidemiological information before the COVID-19 outbreak can be used for use in comparative studies of respiratory virus patterns after the COVID-19 outbreak.

This study was aim to understand the relationship between uncertainty, social isolation, social support and resilience of coronavirus infectious diseases-19 (COVID-19) patients and to identify factors related to resilience. Data were carried out from March 7 to May 5, 2021, and a total of 200 questionnaires were used for data analysis. Data were analyzed with descriptive statistics, t-test, ANOVA, Pearson correlation coefficient and multiple regression using SPSS WIN 24.0 program. As a result of the analysis, the lower the sense of social isolation, the higher the social support, the satisfaction with the explanation of isolation and the economic status of 'medium' were identified as related factors for resilience. Based on the above results, a systematic program should be developed and applied to improve the resilience of COVID-19 patients including strengthening social support through families and health care providers, reducing social isolation through non-face-to-face counseling, providing sufficient information about diseases, and providing economic support.

The purpose of this study is to identify anxiety and depression level for corona virus 19 among hospital nurses to the spread of COVID-19. Data were collected from 232 nurses in 5 hospitals from August to September in 2020 using questionnaire. Characteristics relative to variables were measured, and analyzed using SPSS 26.0 program for descriptive statistics, t-test, ANOVA, and pearson's correlation. The depression level differed according to gender. The anxiety about COVID-19 infection showed a significantly positive correlation to depression (r=.26, p<.001). Based on these results, several roles and coping strategies were suggested to help nurses recover and maintain their psychological stability and mental health.
