RESUMO

Social distance monitoring is of great significance for public health in the era of COVID-19 pandemic. However, existing monitoring methods cannot effectively detect social distance in terms of efficiency, accuracy, and robustness. In this paper, we proposed a social distance monitoring method based on an improved YOLOv4 algorithm. Specifically, our method constructs and pre-processes a dataset. Afterwards, our method screens the valid samples and improves the K-means clustering algorithm based on the IoU distance. Then, our method detects the target pedestrians using a trained improved YOLOv4 algorithm and gets the pedestrian target detection frame location information. Finally, our method defines the observation depth parameters, generates the 3D feature space, and clusters the offending aggregation groups based on the L2 parametric distance to finally realize the pedestrian social distance monitoring of 2D video. Experiments show that the proposed social distance monitoring method based on improved YOLOv4 can accurately detect pedestrian target locations in video images, where the pre-processing operation and improved K-means algorithm can improve the pedestrian target detection accuracy. Our method can cluster the offending groups without going through calibration mapping transformation to realize the pedestrian social distance monitoring of 2D videos. © 2023 World Scientific Publishing Company.

RESUMO

Objectives: To evaluate the safety of inactivated SARS-CoV2 vaccines in liver transplantation recipients. Materials and Methods: This is a cross-sectional observational study. We enrolled stable liver transplantation recipients who had completed the full course of the covid-19 vaccines in our hospital from March 2021 to October 2021. The general adverse reactions and severe adverse events following immunization reported in the LT group were compared to those reported in the general population receiving inactivated covid-19 vaccine. Results: We recruited 151 eligible LT recipients, among which 120 (79.5%) were males, and 31(20.5%) were female. The median age was 56.0 (49.0, 63.0) years old. The median period after LT was 8.44 (4.37, 12.39) years, the median trough concentration of tacrolimus was 2.5 (1.8, 3.9) ng/L. 83 (58.9%) subjects received the CoronaVac vaccine (Sinovac Biotech Ltd), the remaining received Sinopharm Covid-19 vaccine (Beijing Institute of Biological), or compound course of CoronaVac and Sinopharm. The reported incidence of general adverse reaction among LT recipients in the current study was 15.9%, as compared with the reported incidence of 41.7%-46.5% in the general population (Fig. 1A). The prevalence of pain at the injection site, fatigue, headache, pruritus was 9.9%, 5.2%, 1.3%, 0.7% respectively, as compared with the reported 19.4%-27.9%), 10.6-11.2%, 12.6%-13.1%, 1.3%-1.5% in the general population (Fig. 1B). Both inactivated vaccines had similar incidence of adverse reactions. No LT recipients had vaccine related SAE or Covid-19 infection during follow-up despite being residing in areas that had local outbreaks (Beijing, Yunnan, Henan). Conclusion: Covid-19 vaccine was safe in LT recipients. Only a few participants experienced mild reactions such as pain at the injection site and fatigue. (Figure Presented).

RESUMO

The outbreak of COVID-19 has been a critical social event in the past two years. The pandemic has seriously affected the world. Meanwhile, various forms of data about COVD-19 emerge on the Web endlessly, such as SNS discussions, Press releases, WHO statistics, etc. It is valuable work for government departments, news media, and health organizations to integrate and analyze these pandemics-related multi-source data on the web. In this work, we propose an interactive visual analytics system as CVAS that aims at mining and analyzing multi-source data concerned with COVD-19. Having been inspired by the Sankey diagram, we developed a view elaborately. Through appropriate interactions, massive patients' mobility data can be visualized, thus showing the spread features of the pandemic in time and space more specifically. In addition, we collected more than 10,000 trending topics and nearly 10 million related comments on the SNS as Sina Weibo. We performed NLP to analyze their sentiment, identifying key events since the outbreak and the impact of the pandemic on public sentiment. Part of our work was awarded at the China visualization and visual analysis conference (ChinaVis2020) and recognized by peers. © 2022 ACM.

RESUMO

Metaphors in public service advertisements, or PSAs, have played an important role in promoting the knowledge of COVID-19 and China’s anti-epidemic activities. Based primarily on Feng and O’Halloran’s visual representation of multimodal metaphor, this article examines visual and multimodal metaphors created in the online PSAs that were produced in early 2020 to publicize China’s epidemic prevention and control activities. It is found that those metaphors fall into three general groups, namely “coronavirus” metaphor, “anti-epidemic worker” metaphor, and “medical instrument” metaphor. Nearly all of them were created to serve an overarching metaphor, namely ANTI-EPIDEMIC WORK IS WAR, of which coronaviruses were depicted as enemies, anti-epidemic workers as warriors, and medical instruments as weapons. Most of the metaphors were constructed through visual or multimodal anomaly realized through strategies such as participant substitution, verbal/visual superimposition, and verbo-visual integration/fusion in the representational structure, while their metaphorical meanings became supplemented or reinforced by the deployment of compositional and interactive resources such as spatial position, color contrast, gaze, and size. Finally, the causes and implications of the findings are discussed from three aspects: social background, genre, and audience. © The Author(s) 2022.

RESUMO

COVID-19 marks one of the most challenging year in human history with unprecedented globalization challenges. However, there is a silver lining in the midst of such challenges in that it invigorated intensive and unlimited academic cooperation at grass-roots level between the world’s two most ancient civilizations, India and China. It was a year of 1st Indo-China Research Webinar Series featuring over 5000 participants, 16 technical sessions and 10 Special Guests. Under normal circumstances, this clearly would not be possible. After all, generally, it would have required at least a year of detailed planning coupled with significant funding. The success of the series stood on the foundation of the past several years of scientific collaborations. This chapter describes this scientific cooperation in terms of youth exchange (2-way) between outstanding universities from both countries. In addition, the impact of such cooperation in terms of Joint International Research Awards has also been presented. Still, what is presented here is still only the tip of iceberg of the impact of scientific cooperation between the youth of both countries in past few years. Undoubtedly, a great deal still needs to be done to further deepen relations in people to people exchange at the scientific level between both countries, especially in seeking solutions to scientific issues of mutual interest, especially in the global existential challenges of climate change and the economic future of sustainable infrastructure development for humanity. © 2021, The Author(s), under exclusive license to Springer Nature Singapore Pte Ltd.

RESUMO

The novel severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) is the cause of a rapidly spreading illness, coronavirus disease 2019 (COVID-19), affecting more than seventeen million people around the world. Diagnosis and treatment guidelines for clinicians caring for patients are needed. In the early stage, we have issued "A rapid advice guideline for the diagnosis and treatment of 2019 novel coronavirus (2019-nCoV) infected pneumonia (standard version)";now there are many direct evidences emerged and may change some of previous recommendations and it is ripe for develop an evidence-based guideline. We formed a working group of clinical experts and methodologists. The steering group members proposed 29 questions that are relevant to the management of COVID-19 covering the following areas: chemoprophylaxis, diagnosis, treatments, and discharge management. We searched the literature for direct evidence on the management of COVID-19, and assessed its certainty generated recommendations using the Grading of Recommendations, Assessment, Development and Evaluation (GRADE) approach. Recommendations were either strong or weak, or in the form of ungraded consensus-based statement. Finally, we issued 34 statements. Among them, 6 were strong recommendations for, 14 were weak recommendations for, 3 were weak recommendations against and 11 were ungraded consensus-based statement. They covered topics of chemoprophylaxis [including agents and Traditional Chinese Medicine (TCM) agents], diagnosis [including clinical manifestations, reverse transcription-polymerase chain reaction (RT-PCR), respiratory tract specimens, IgM and IgG antibody tests, chest computed tomography, chest X-ray, and CT features of asymptomatic infections], treatments [including lopinavir-ritonavir, umifenovir, favipiravir, interferon, remdesivir, combination of antiviral drugs, hydroxychloroquine/chloroquine, interleukin-6 inhibitors, interleukin-1 inhibitors, glucocorticoid, Qingfei Paidu decoction, Lianhua Qingwen granules/capsules, convalescent plasma, lung transplantation, invasive or noninvasive ventilation, and extracorporeal membrane oxygenation (ECMO)], and discharge management (including discharge criteria and management plan in patients whose RT-PCR retesting shows SARS-CoV-2 positive after discharge). We also created two figures of these recommendations for the implementation purpose. We hope these recommendations can help support healthcare workers caring for COVID-19 patients. © 2020 People's Military Medical Press. All rights reserved.
