ABSTRACT

This study aims to evaluate university students' daily activities and the effect of physical activity on physical fitness, especially during the COVID-19 pandemic. This research used comparative and correlational research methods. Thirty research samples consisted of 13 junior year university students and 17 senior year university students were selected by the purposive sampling method. Every student was monitored for their daily activities for one week and categorized into sports, college, organization, and other activities. Physical fitness was measured using the MFT test to measure the VO2Max in ml/kg/min units. The data analysis results showed no significant difference between junior and senior semester students in VO2Max, physical exercise, organizational activities, lecture activities, sleeping, and other activities. There was a significant difference in VO2Max and physical exercises (sig < 0.05) between genders. Male students spent more time exercising (17.87 ± 11.1) than female students (10.80 ± 6.04). Furthermore, male students had a higher average VO2Max (42.38 ± 7.53) than female students (29.36 ± 6.07). Based on the regression analysis results, there is a significant value between physical exercises and sleeping toward VO2Max capacity (sig. < 0.05). © 2022 by authors.

ABSTRACT

Purpose: This study explored the students' perception of their adoption and acceptance of virtual learning (VL), the factors affecting the adoption of educational technologies and the correlation between their intention, perceived behavioral control and care competence in caring for older adults. Design/methodology/approach: A cross-sectional survey was conducted. Surveys were administered to evaluate the participants who were involved in VL on geriatric care during coronavirus disease 2019 (COVID-19) pandemic. A total of 315 nursing students participated in the survey, and 287 valid questionnaires were collected (response rate: 91.11%). Findings: A total of 287 participants (mean age 21.09, SD 1.44 years;242/287, 84.3% female) were included in the study. The variables of intention to use technologies were positively correlated with care competence (r = 0.59, p < 0.001). The results revealed that the major predictors were perceived ease-of-use (PEOU) (β = 0.28, 95% confidence interval (CI) 0.16–0.40) and perceived usefulness (PU) (β = 0.22, CI 0.09–0.35) which were significantly positive predictors of competence in geriatric care. Research limitations/implications: Nursing students lack in clinical knowledge and situational experience in geriatric care;therefore, their perceptiveness, expressions and reflection on the process of providing care to hospitalized older patients should be increased. These results indicated that students improved in geriatric healthcare after/during the VL program during COVID-19 pandemic. Originality/value: It is hoped that the present study would make an invaluable contribution to existing research on education in general and on the quality of care in geriatric nursing as limited studies have been published so far. © 2022, Pei-Lun Hsieh, Shang-Yu Yang, Wen-Yen Lin and Tien-Chi Huang.

ABSTRACT

Coronavirus disease of 2019(COVID-19) is a highly contagious viral disease, causing reparatory symptoms, ranging from flu-like symptoms to acute respiratory distress. Since the end of 2019, COVID-19 has posed a tremendous threat to the healthcare systems nationwide. Multiple public health interventions, including mandating social distancing, closing outpatient visits, or postponing elective procedures have been implemented to mitigate the impact on disease transmission and prevent consumption of medical resources. Since the beginning of the pandemic, resources have been shifted away from chronic disease management and prevention. Osteoporosis, a chronic condition, which requires continuous and concerted medical attention to alleviate the long-term consequences such as osteoporotic fractures, morbidities, or mortalities. In this review article, we will discuss the strategies to cope with osteoporosis, especially focusing on pharmaceutical management considerations during the era of COVID-19 pandemic. We will also discuss different drug distribution models when outpatient clinics are not readily available or mandatory social distancing policy is employed. After all, we will propose alternative therapeutic options when the continuity of particular medications cannot be maintained. © 2021 Society of Internal Medicine of Taiwan. All rights reserved.

ABSTRACT

Between COVID-19 and the ongoing trade friction between China and the United States, the domestic and international economic situations have become much more complicated. In this context, what is of vital importance is studying the impact of exchange rate fluctuations on trade balance from two perspectives, namely China's international balance of payments and maintaining the smooth operation of the domestic economy. Economists at home and abroad have done considerable research into the relationship between exchange rate fluctuations and trade balance. However, few studies to date have examined the relationship from the perspective of exchange rate pass-through. This paper reviews relevant theories about exchange rate pass-through (EPT in short) and its impact on trade balance, both at home and abroad. A literature review on empirical studies of the relationship between exchange rate pass-through (EPT) and trade balance is also conducted. After that, a brief conclusion of the literature is made. As a result, the findings of this research can provide a reference platform for future scholars who choose to study the relationship between exchange rate fluctuation and its influence on trade balance, from the exchange rate pass-through (EPT) perspective. © 2021 Kriedt Enterprises Ltd.

ABSTRACT

Today, the most serious threat to global health is the continuous outbreak of respiratory diseases, which is called Coronavirus Disease 2019 (COVID-19). The outbreak of COVID-19 has brought severe challenges to public health and has attracted great attention from the research and medical communities. Most patients infected with COVID-19 will have fever. Therefore, the monitoring of body temperature has become one of the most important basis for pandemic prevention and testing. Among them, the measurement of body temperature is the most direct through the Forehead Thermometer, but the measurement speed is relatively slow. The cost of fast-checking body temperature measurement equipment, such as infrared body temperature detection and face recognition temperature machine, is too high, and it is difficult to build Disease Surveillance System (DSS). To solve the above-mentioned problems, the Intelligent pandemic prevention Temperature Measurement System (ITMS) and Pandemic Prevention situation Analysis System (PPAS) are proposed in this study. ITMS is used to detect body temperature. However, PPAS uses big data analysis techniques to prevent pandemics. In this study, the campus field is used as an example, in which ITMS and PPAS are used. In the research, Proof of Concept (PoC), Proof of Service (PoS), and Proof of Business (PoB) were carried out for the use of ITMS and PPAS in the campus area. From the verification, it can be seen that ITMS and PPAS can be successfully used in campus fields and are widely recognized by users. Through the verification of this research, it can be determined that ITMS and PPAS are indeed feasible and capable of dissemination. The ITMS and PPAS are expected to give full play to their functions during the spread of pandemics. All in all, the results of this research will provide a wide range of applied thinking for people who are committed to the development of science and technology.

ABSTRACT

The first case of Corona Virus Disease 2019 (COVID-19) was reported in Wuhan, China in December 2019. Since then, COVID-19 has quickly spread out to all provinces in China and over 150 countries or territories in the world. With the first level response to public health emergencies (FLRPHE) launched over the country, the outbreak of COVID-19 in China is achieving under control in China. We develop a mathematical model based on the epidemiology of COVID-19, incorporating the isolation of healthy people, confirmed cases and contact tracing measures. We calculate the basic reproduction numbers 2.5 in China (excluding Hubei province) and 2.9 in Hubei province with the initial time on January 30 which shows the severe infectivity of COVID-19, and verify that the current isolation method effectively contains the transmission of COVID-19. Under the isolation of healthy people, confirmed cases and contact tracing measures, we find a noteworthy phenomenon that is the second epidemic of COVID-19 and estimate the peak time and value and the cumulative number of cases. Simulations show that the contact tracing measures can efficiently contain the transmission of the second epidemic of COVID-19. With the isolation of all susceptible people or all infectious people or both, there is no second epidemic of COVID-19. Furthermore, resumption of work and study can increase the transmission risk of the second epidemic of COVID-19.

ABSTRACT

Objective: To evaluate the efficacy and safety of lopinavir/ritonavir (LPV/r) and arbidol in treating patients with coronavirus disease 2019 (COVID-19) in the real world. Methods: The clinical data of 178 patients diagnosed with COVID-19 admitted to Guangzhou Eighth People's Hospital from January 20 to February 10, 2020 were retrospectively analyzed. According to patient's antiviral treatment regimens, 178 patients were divided into 4 groups including LPV/r group (59 patients), arbidol group (36 patients), LPV/r plus arbidol combination group (25 patients) and the supportive care group without any antiviral treatment (58 patients). The primary end point was the negative conversion time of nucleic acid of 2019 novel coronavirus (2019-nCoV) by pharyngeal swab. Results: The baseline parameters of 4 groups before treatment was comparable. The negative conversion time of viral nucleic acid was (10.20±3.49), (10.11±4.68), (10.86±4.74), (8.44±3.51) days in LPV/r group, arbidol group, combination group, and supportive care group respectively (F=2.556, P=0.058). There was also no significant difference in negative conversion rate of 2019-nCoV nucleic acid, the improvement of clinical symptoms, and the improvement of pulmonary infections by CT scan (P>0.05). However, a statistically significant difference was found in the changing rates from mild/moderate to severe/critical type at day 7 (χ(2)=9.311, P=0.017), which were 24%(6/25) in combination group, 16.7%(6/36) in arbidol group, 5.4%(3/56) in LPV/r group and 5.2%(3/58) in supportive care group. Moreover, the incidence of adverse reactions in three antiviral groups was significantly higher than that in supportive care group (χ(2)=14.875, P=0.002). Conclusions: Antiviral treatment including LPV/r or arbidol or combination does not shorten the negative conversion time of 2019-nCoV nucleic acid nor improve clinical symptoms. Moreover, these antiviral drugs cause more adverse reactions which should be paid careful attention during the treatment.

ABSTRACT

Rapid detection of body fluid severe acute respiratory syndrome coronavirus 2(SARS-CoV-2) antibody is an effective strategy for infection therapeutic effect of coronavirus disease(COVID-19). Most detection methods require relatively large equipment, which limited their on-site application. Lateral flow immunoassay(LFIA) can be used to qualitative antibody detection based on the aggregation of gold nanoparticles (Au NPs), which exhibits just one-color change and cannot realize rapid quantitative detection without the help of additional equipment. In this study, a high-resolution multicolor colorimetric strategy was developed and applied to assessing antibody concentration at a glance based on etching of gold nanorods(Au NRs). Firstly, SARS-CoV-2 recombinant antigen was immobilized on the surface of the 96-wells. Then, horseradish peroxidase(HRP)-labeled second antibody combined with antibody to form an antigen-antibody-secondary antibody complex on the well surface, which has direct relationship with antibody concentration in the sample and can be used to oxidize 3, 3', 5, 5'-tetramethylbenzidine(TMB) to form TMB2+ at the presence of HRP. The generation of TMB2+ efficiently etch Au NRs to produce multicolor solution. The etching result in vivid color changes in the system has a relationship with the amount of SARS-CoV-2 IgM antibody. Under the optimal conditions, the proposed strategy exhibited a linear response in the 5.00―200 IU concentration range, and a detection limit of 1.29 IU for SARS-CoV-2 IgM antibody, with high sensitivity and specificity. This assay is prospective for the on-site semi-quantitative visual detection of SARS-CoV-2 IgM antibody concentration in the COVID-19 therapeutic process. © 2021, Editorial Department of Chem. J.

ABSTRACT

Background: Dysregulated immune responses to severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) are thought to underlie the progression of coronavirus disease 2019 (COVID-19). We sought to further characterize host antiviral and cytokine gene expression in COVID-19 patients based on illness severity. Methods: In this case-control study, we retrospectively analyzed 46 recovered COVID-19 patients and 24 healthy subjects (no history of COVID-19) recruited from the Second People's Hospital of Fuyang City. Blood samples were collected from each study participant for RNA extraction and PCR. We assessed changes in antiviral gene expression between healthy controls and patients with mild/moderate (MM) and severe/critical (SC) disease. Results: We found that type I interferon signaling (IFNA2, TLR8, IFNA1, IFNAR1, TLR9, IRF7, ISG15, APOBEC3G, and MX1) and genes encoding proinflammatory cytokines (IL12B, IL15, IL6, IL12A and IL1B) and chemokines (CXCL9, CXCL11 and CXCL10) were upregulated in patients with MM and SC disease. Moreover, we found that IFNA1, apolipoprotein B mRNA editing enzyme, catalytic polypeptide-like 3G (APOBEC3G), and Fas-associated protein with death domain (FADD) were significantly downregulated (P < 0.05) in the SC group compared to the MM group. We also observed that microRNA (miR)-155 and miR-130a levels were markedly higher in the MM group compared to the SC group. Conclusion: COVID-19 is associated with the activation of host antiviral genes. Induction of the IFN system appears to be particularly important in controlling SARS-CoV-2 infection, as decreased expression of IFNA1, APOBEC3G and FADD genes in SC patients, relative to MM patients, may be associated with disease progression.

ABSTRACT

How to understand the role and impact of information technology and artificial intelligence has triggered a big debate. To explore the pros and cons of artificial intelligence and its applications, this article takes the face mask distribution programs in the COVID-19 pandemic as research objects, conducting a multi-case comparative study of three cities in China. By manual coding of a total of 4560 We Chat official account messages, and by analyzing information related to the distribution process, it was found that: (1) On the demand side, the task complexity, the demand diversity, and the unstructured decision-making process in the public health emergency have exposed some limitations of AI in data collecting and unstructured problem-solving. (2) On the supply side, the procedural and substantive rules designed, together with the reliability of an AI system, will shape the performance of the AI service channel. (3) Though AI and other new technologies are advancing drastically in the pandemic, there is still much room for improvement whether by the optimization of AI systems, or by political control and social participation, and by the supplement of alternative channels such as the community service delivery. © 2021 IEEE.

ABSTRACT

The outbreak of the COVID -19 pandemic is accompanied by numerous rumors spreading on the social media platform, which seriously affects the stability of society and the safety of public. Existing quantitative analyses of COVID -19 related social media rumors only focus on single element of communication, such as content, while ignoring other basic elements of communication, including communicator, audience, and effect. Besides, compared with the real social media rumor data, the rumor data of these studies have distribution bias and lack of information. Therefore, we conduct a more comprehensive quantitative analysis on the communication of COVID -19 related social media rumors based on the Sina Weibo platform. Specifically, we first analyze the communication content of rumors, including the analysis of the topic, involved regions, event tendency and sentiment. Further, we investigate the users engaged in rumor communication and divide the users into three categories, namely, rumor posters, rumor spreaders, and rumor informers. We explore the basic attributes, topic preferences, individual sentiments, and self-network characteristics of the engaged users. Finally, we study the public opinion triggered by rumors, including the overall sentiment distribution, its correlation with topics, keywords and regions, as well as the evolution of sentiment. To conclude, this study first quantitatively analyzes COVID -19 related social media rumors from the perspective of different basic elements in communication. It provides a more comprehensive and profound understanding of COVID -19 related social media rumors and is of great value for both research and management of rumor in public emergencies. © 2021, Science Press.

ABSTRACT

Purpose: Drawing on self-determination theory (Deci and Ryan, 2012) and Hew’s (2016) five-factor model, our study aimed to investigate the impact of two online training design factors (instructor accessibility and active learning) on learner’s self-efficacy and learning outcome amid the COVID-19 pandemic. Design/methodology/approach: A randomized pretest-posttest control group field experiment was designed to assess participants’ self-efficacy and learning outcome of an online training program - territory business management plan, under three conditions: instructor accessibility, active learning, and controlled. Participants (N=87) were medical sales representatives from a Fortune-Global 500 pharmaceutical company’s subsidiary office in China. Data was analyzed with 2 (time) x 3 (group) MANOVA with time (pretest and posttest) as a repeated measure to investigate differences in changes in self-efficacy and learning outcome between three groups. Findings: Overall, participants’ self-efficacy and learning outcome were significantly improved via the online training program for all three groups. Specifically, the impact of the training on learning outcome was the strongest for the active learning group, less strong for the instructor accessibility group, and the least strong for the control group. Originality/value: Our research contributes towards understandings of the effectiveness of online talent training programs by examining two critical instructional design factors during a time of crisis. Our findings suggest that active learning (interactions with the training materials by purposeful self-reflection) might be a stronger predictor for increasing learning outcome than instructor accessibility (receiving feedback and tutoring sessions from the instructor) for online training programs. © 2021, Emerald Publishing Limited.

ABSTRACT

Objective: To investigate the management strategies for lung transplant patients in Wuhan areas during the COVID-19 epidemic period (from January 1, 2020 to April 8, 2020). Methods: During the epidemic period in Renmin Hospital of Wuhan University, three potential lung transplant patients on the waiting list were suspended for operation, one who underwent lung transplantation was carefully quarantined and the surrounding environment was disinfected, nine patients after lung transplantation received epidemic prevention instructions and were followed up through phone call or online communication. The clinical and follow-up data of these patients were collected and analyzed. Results: The patient with lung transplantation performed in the early stage of the epidemic was survived and didn't infected with SARS-CoV-2. Of the postoperative cases, only one was infected with SARS-CoV-2 which eventually caused death during the epidemic. Conclusion: During the COVID-19 epidemic, effective management strategies adopted in affected areas could reduce the incidence of SARS-CoV-2 infection in lung transplant patients. © 2021, Editorial Board of Medical Journal of Wuhan University.

ABSTRACT

The coronavirus crisis could be the impetus the industry needs to establish telemedicine as a widespread option for access to healthcare. The Centers for Medicare and Medicaid Services have changed eligibility requirements and reimbursement limits to stem the spread of the disease, and many other payers are following suit. Payment models and regulations that have been hampering growing virtual care options for years are adapting to allow waves of patients to access their providers via telemedicine. © 2021 by Nova Science Publishers, Inc.

ABSTRACT

This Perspective piece marks the ten-year anniversary of Transfers' life as a journal and its contributions to aeromobilities research. Reflecting on my own past decade learning and writing about aeromobilities, the article takes stock of some significant threads in the field, before charting out three key future directions for aeromobilities research prompted by the COVID-19 pandemic and health crisis. Without prejudice to existing scholarly threads, the article discusses the burgeoning salience of new (aero)mobility injustices, automation, and aerial (in)civilities, amid an aviation industry struggling to reboot itself. The next ten years present enduring possibilities for aeromobilities inquiries, and the article hopes to inspire future thinking on the subject as societies connect again through aviation.
