ABSTRACT
The recent outbreak of COVID-19 has had colossal repercussions for all economic agents including households, corporations, and governments worldwide. Each economic agent responded in their own way to mitigate or at least diminish the scale of that impact. Small and medium-sized enterprises (SMEs) also countered the COVID-19 pandemic to their highest capacity despite being more vulnerable to crises. Many SMEs experienced shutdowns or declared bankruptcy due to the ineptitude and lack of financial resources or effective strategic response to cope with this unprecedented shock. In this paper, we assess the impact of the COVID-19 pandemic coping strategies such as adjusting the process and product, shifting business activity online, and remote working arrangements on SMEs' access to finance. Using the World Bank's COVID-19 impact survey data collected between 2020 and mid-2021 from 42 countries, we find that better strategies adopted by SMEs increase their likelihood of getting new credit from government and commercial banks. The results remain robust to alternative test settings. Our findings offer significant and timely contributions to SMEs' access to finance and to the practicing managers on adopting and adjusting strategies in response to crises or disruptions. © 2023 Informa UK Limited, trading as Taylor & Francis Group.

ABSTRACT
The exponential rise of healthcare problems like human aging and road traffic accidents have developed an intrinsic challenge to biomedical sectors concerning the arrangement of patient-specific biomedical products. The additively manufactured implants and scaffolds have captured global attention over the last two decades concerning their printing quality and ease of manufacturing. However, the inherent challenges associated with additive manufacturing (AM) technologies, namely process selection, level of complexity, printing speed, resolution, biomaterial choice, and consumed energy, still pose several limitations on their use. Recently, the whole world has faced severe supply chain disruptions of personal protective equipment and basic medical facilities due to a respiratory disease known as the coronavirus (COVID-19). In this regard, local and global AM manufacturers have printed biomedical products to level the supply-demand equation. The potential of AM technologies for biomedical applications before, during, and post-COVID-19 pandemic alongwith its relation to the industry 4.0 (I4.0) concept is discussed herein. Moreover, additive manufacturing technologies are studied in this work concerning their working principle, classification, materials, processing variables, output responses, merits, challenges, and biomedical applications. Different factors affecting the sustainable performance in AM for biomedical applications are discussed with more focus on the comparative examination of consumed energy to determine which process is more sustainable. The recent advancements in the field like 4D printing and 5D printing are useful for the successful implementation of I4.0 to combat any future pandemic scenario. The potential of hybrid printing, multi-materials printing, and printing with smart materials, has been identified as hot research areas to produce scaffolds and implants in regenerative medicine, tissue engineering, and orthopedic implants.
ABSTRACT
: The novel coronavirus has infected over 609,848,852 individuals throughout the world with a total death of over 6.5 million since its outbreak in December 2019. Since then many therapeutic options have been approached and tested in clinical trials as well to find a potential cure or preventive therapy for the COVID-19 disease. This review summarizes the potential therapeutic options currently available for the treatment of COVID-19 including lopinavir-ritonavir, Hydroxychloroquine, Remdesivir, Ribavirin, dexamethasone, interferon, antibodies, Tocilizumab, Azithromycin, Piperacillin-tazobactam, Moxifloxacin, Ivermectin, Nitazoxanide, Baricitinib, and Arbidol. This study briefly discusses the clinical trials and encompasses the dosage, efficacy, adverse drug reactions, and possible mechanism of action of the potential treatment candidate where applicable. The growing number of reported cases posits an exigent need for a suitable therapy for the prevention and cure of this disease. Therefore, the study aims to provide vital information on each drug to highlight the latest scientific research that could be helpful for better prevention/treatment of COVID-19 disease.
ABSTRACT
Background: Coronavirus Disease-2019 (COVID-19) has appeared as a deadly pandemic affecting most of the countries across the world. The disease has caught humanity unprepared;therefore, there has been a lack of awareness about the causes, and transmission and mortality rates. It has also affected the overall socioeconomics from individual to worldwide levels. COVID-19 is an unprecedented and first-time challenge for Pakistan and a lockdown imposed by the Government of Pakistan has further devastated the economy of the country. This online survey was conducted to know the effects of the Covid-19 pandemic on the social life and economic status of the people of Pakistan. In this article, we mainly focused on teachers and students from different Universities of Pakistan for data generation because they can provide better information due to the use of modern technologies as a source of information. Methods: An online questionnaire survey covering 11 parameters including age, gender, employment status, mortality rate, education, marital status and, information about the pathogen responsible for the disease was filled by 1260 individuals from Pakistan. Results: The results obtained show that 56.6% of the responders were males,43.4% were females, 59.9% were unmarried, 37.7% were graduate students and, 48.7% unemployed. Most of the responders (55.6%) said that COVID-19 negatively affected the jobs of the people. We found (93%) of the responders with good knowledge about COVID-19. Conclusion: We conclude from the results that most of the responders were males, educated and they knew the pathogenic effect of the COVID-19 virus on humans. These results also show that the disease has drastically affected the economy and social life of the people of Pakistan.
ABSTRACT
Purpose Additive manufacturing (AM) technology has a huge influence on the real world because of its ability to manufacture massively complicated geometrics. The purpose of this study is to use CiteSpace (CS) visual analysis to identify fused deposition modeling (FDM) research and development patterns to guide researchers to decide future research and provide a framework for corporations and organizations to prepare for the development in the rapid prototyping industry. Three-dimensional printing (3DP) is defined to budget minimize manufactured input and output for aviation and the medical product industrial sectors. 3DP has implemented its potential in the Coronavirus Disease of 2019 (COVID-19) reaction. Design/methodology/approach First, 396 original publications were extracted from the web of science (WOS) with the comprehensive list and did scientometrics analysis in CS software. The parameters are specified in CS including the span (from 2011 to 2019, one year slice for the co-authorship and the co-accordance analysis), visualization (show the merged networks), specific criteria for selection (top 20%), node form (author, organization, region, reference cited;cited author, journal and keywords) and pruning (pathfinder and slicing network). Finally, correlating data was studied and showed the results of the visualization study of FDM research were shown. Findings The framework of FDM information is beginning to take shape. About hot research topics, there are "Morphology," "Tensile Property by making Blends," "Use of Carbon nanotube in 3DP" and "Topology optimization." Regarding the latest research frontiers of FDM printing, there are "Fused Filament Fabrication," "AM," in FDM printing. Where "Post-processing" and "environmental impact" are the research hotspots in FDM printing. These research results can provide insight into FDM printing and useful information to consider the existing studies and developments in FDM researchers' analysis. Research limitations/implications Despite some important obtained results through FDM-related publications' visualization, some deficiencies remain in this research. With >99% of articles written in English, the input data for CS was all downloaded from WOS databases, resulting in a language bias of papers in other languages and neglecting other data sources. Although, there are several challenges being faced by the FDM that limit its wide variety of applications. However, the significance of the current work concerning the technical and engineering prospects is discussed herein. Originality/value First, the novelty of this work lies in describing the FDM approach in a Scientometric way. In Scientometric investigation, leading writers, organizations, keywords, hot research and emerging knowledge points were explained. Second, this research has thoroughly and comprehensively examined the useful sustainability effects, i.e. economic sustainability, energy-based sustainability, environmental sustainability, of 3DP in industrial development in qualitative and quantitative aspects by 2025 from a global viewpoint. Third, this work also described the practical significance of FDM based on 3DP since COVID-19. 3DP has stepped up as a vital technology to support improved healthcare and other general response to emergency situations.
