A novel coronavirus emerged in human populations and spread rapidly to cause the global coronavirus disease 2019 pandemic. Although the origin of the associated virus (severe acute respiratory syndrome coronavirus 2 [SARS-CoV-2]) remains unclear, genetic evidence suggests that bats are a reservoir host of the virus, and pangolins are a probable intermediate. SARS-CoV-2 has crossed the species barrier to infect humans and other animal species, and infected humans can facilitate reverse-zoonotic transmission to animals. Considering the rapidly changing interconnections among people, animals, and ecosystems, traditional roles of veterinarians should evolve to include transdisciplinary roles.

In this paper, we examine the shortening of the theatrical window whereby films play at theaters for 90 days as one of the most portentous issues that could reshape the Hollywood film industry. We first examine the windows system that protected the status of movie theaters and the studios' attempt to shorten the theatrical release to create a premium VOD window in response to the declining revenue of DVDs after 2007 and the rise of streaming services. We then look at some of the major disruptions in distribution COVID-19 brought about. We also explore the shortening of the theatrical release in the wake of the pandemic and shows the changes in the theatrical release, along with the expansion of streaming services, raise questions over the long-held primacy of the theatrical release and the definition of film with the theatrical release as its part. From this, we highlight Hollywood at the crossroads of major changes with its future less certain than ever before.

Purpose: This study aims to confirm the effect of clinical practice on dental technology students by comparing preclinical expectations and post-training satisfaction of dental technology students in Suwon-si, Gyeonggi-do during the coronavirus disease pandemic. Methods: This study included students enrolled in the Department of Dental Technology of D University in Suwon-si, Gyeonggi-do. The purpose of the study was explained in advance and 70 students agreed to participate in the survey. IBM SPSS Statistics version 18.0 was used for data analysis and the significance level was tested at p=0.05. Results: There were significant differences in clinical practice content, operation, institutional expectations, and satisfaction. Conclusion: Based on the differences in expectations and satisfaction in this study, schools, industries, and associations can study ways to increase satisfaction in terms of clinical practice content, operation, and institution to present directions for dental technology and clinical practice.

본 연구에서는 코로나19 팬데믹에서 서비스산업종사자들의 직업 불안이 삶의 만족에 미치는 영향 관계를 알아보고자 연구를 진행하였다. 거기에 가족지지의 매개효과를 검증하고자 하였다. 2019년말에 발생한 코로나19는 세계적으로 한 번도 경험해 보지 못한 새로운 세상을 경험하고 있다. 자국의 국민을 보호하고자 국제 공항은 외국의의 출입을 철저히 봉쇄함으로써 코로나 확산을 막았고, 그로인하여 세계 경제교역은 큰 타격을 받았다. 산업관련 물동량은 점차 회복되고 있으나 여행객을 포함한 인적교류는 아직도 힘든 상황으로 호텔업, 관광업등의 서비스산업은 상당한 영향을 받아 거기에 종사하는 직원들 또한 자신의 직업에 대한 불안이 늘고 있다. 2021년 현재 대부분의 나라에서 위드코로나 정책으로 전환하면서 서비스산업이 점차 회복되고 있으나 아직도 힘든 상황을 보내고 있다. 따라서 본 고는 포스트 코로나시대에 서비스산업종사자들의 직업불안을 낮게 하고 삶의 만족을 높이는 방안을 제시하고자 하였다.

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.

Metaverse is a field that is growing explosively along with the COVID-19 pandemic. However, it can be seen from several cases that the existing concept of Mebatus is not misunderstood or that a new one has not appeared. It is hoped that an approach similar to this article will be helpful in the metavassus era to be developed in the future.

This study compares these two platforms with Gedertown and Zepeto, which have the largest number of users among metaverse that have grown rapidly due to various factors such as COVID-19 pandemic. It focuses on the differences between avatars, usage fees, class rooms, and communication methods. Accordingly, the difference between 2D and 3D of the metaverse platform and the difference in camera use can be seen.

The COVID-19 pandemic had substantial negative impacts and caused several disruptions to the global supply chain of the shipping industry. The key challenges identified in terms of maritime manpower are the Certificates of Competency (CoC) or the expiration and/or failure to complete refresher and/or revalidation courses, which directly hinder employment retention and lost opportunities at sea. To tackle this issue directly and swiftly, the creation of the APEC SEN Distance Learning Platform was suggested and approved by APEC as part of an official project. This paper introduces the APEC-wide accessible distance learning platform with the following key topics: the organisation and operation of the platform, the themes and content to be prioritised, the process of education, training, certification, and the ways to promote accreditation, mutual recognition on CoC, education and training videos by taking collaborative actions, and the development of content.

In this study, we propose a dynamic SEIQRV mathematical model and examine it to comprehend the dynamics of COVID-19 pandemic transmission in the Coimbatore district of Tamil Nadu. Positiveness and boundedness, which are the fundamental principles of this model, have been examined and found to be reliable. The reproduction number was calculated in order to predict whether the disease would spread further. Existing arrangements of infection-free, steady states are asymptotically stable both locally and globally when R₀ < 1. The consistent state arrangements that are present in diseases are also locally steady when R₀ < 1 and globally steady when R₀ > 1. Finally, the numerical data confirms our theoretical study.

This study proposed a novel model to investigate influential factors affecting the intention to continue using increasingly popular food delivery apps (FDAs). The proposed theoretical model is developed and validated to extend traditional technology acceptance and adoption theories by identifying several determinant factors that capture the unique context of FDAs continuous usage. Hypotheses were tested using a partial least square structural equation modeling approach (PLS-SEM) on data collected from 331 actual FDAs users during the COVID-19 pandemic. The results reveal that convenience, perceived compatibility, delivery experience, and online reviews significantly influence the continuous usage of FDAs. The findings also confirm the importance of continuous intention on the actual use of FDAs. The research model of this study explains 65% of variance in continuous intention and 47% in actual use. The insights provided by this study suggest fruitful directions for future research. They can also help FDAs companies, developers and marketers with strategies and tips for further development and growth by ensuring users' continuous usage of these platforms.
