ABSTRACT
In today's Era,various industries are settling up in India and tourism is one of them. Tourism being one of the leading industries in India has set up the benchmark within last few years. Talking about today's scenario, the tourism industry is facing a huge loss because of the deadly humanitarian disease "COVID-19"that came at the end of 2019. It had led to the LOCKDOWN nationwide, leading towards the downfall of the hotel and tourism industry. Global covid-19 pandemic has challenged this sensitive industry with unprecedented circumstances and repercussions. Although, after the second wave, the situation is becoming better day by day, the tourist visits at famous stations have increased rapidly that may be harmful for the country and virus may further spread to the country and there are several reasons for increase in the tourist visit at different parts of the globe. These reasons have been considered as criteria for the study. The main objective of this work is to find out the main reasons why people are getting attracted towards tourism. In this work an AHP approach been proposed to solve the above discussed problem. Total seven criteria's have been taken from expert opinions which have been considered for study. It has been found that the reason "Upcoming 3rd Wave"has the maximum impact than other reasons for increment of people at tourist places. © 2023 Author(s).
ABSTRACT
COVID-19 has wreaked havoc on the global economy, supply chains, and government, posing an unparalleled health threat. The manufacturing sector was one of the most disruptive systems in the world at the time of the COVID-19 pandemic. Most manufacturing companies have faced a lock-down situation and are focusing on the production of essential products. Furthermore, COVID-19 has altered customer behavior. The short-term and long-term effects of COVID-19 on the manufacturing sector must be evaluated to hasten recovery and build preparedness measures should another such disruption occur. The limitations affecting the construction system during this period were discussed and prioritized in this study. The ambiguous nature of human thinking makes it difficult to evaluate the qualitative parameters;hence, it is preferred to incorporate an approach that converts the variables into triangular fuzzy numbers to better represent the values of the criteria. A fuzzy analytical hierarchical procedure (FAHP) is applied to evaluate the limitation criteria in an ambiguous environment. "Growing demand for existing products" is considered the heaviest limit after "financial stagnation" and "setback in logistics services." The study results will help the manufacturing company in formulating and implementing strategies to overcome the pandemic situation. © 2023 River Publishers. All rights reserved.
ABSTRACT
In this paper, there are four distinct models utilized for the retrieval of CSPM from the Sentinel 2A/2B satellite imageries by using cloud computing techniques. In this study, a comparative analysis of different CSPM models was carried out at three different sites (Haridwar, Varanasi, and Hooghly). The study reveals that there are significant changes in CSPM in the Ganges in three different periods such as pre, during, and post-COVID. Noteworthy, fewer anthropogenic activities have generated important transformations in aquatic environments during the COVID. © 2023 IEEE.
ABSTRACT
Introduction: COVID-19 disease is caused by SARS-CoV-2 virus and it was declared pandemic by World Health Organization (WHO) on March 11,2020. The coronavirus infection has an affinity for ACE2 receptors and by attaching to them, the virus enters the host cells. Along with many body organs like lungs, kidney, liver, upper respiratory tract, nervous system, skeletal muscles, ACE2 concentration is also found in abundance in epithelial cells of tongue and salivary glands. Materials and Methods: Recent studies, researches, documents and case reports published in the world medical literature in the year 2020-2021 were searched and documented in our study. The search engines used were PUBMED, google scholar, WEB OF SCIENCE etc. Results: Dysgeusia, xerostomia, sore throat, aphthous and herpetiform ulcers, candidiasis, enanthema, Kawasaki like lesions were the most common among various oral manifestations. Others includes plaque like changes, gingival inflammation, necrotizing gingivitis, erythema - multiforme, angina-bullosa like lesions, Melkersson-Rosenthal Syndrome, Oral mucormycosis etc.The sites of infection mainly include tongue, gingiva, hard and soft palate, buccal and labial mucosa etc. Conclusion: The etiopathogenesis of such lesions cannot be directly corelated with COVID-19 and factors such as stress, immunosuppression, co-infections, secondary lesions, opportunistic infections, systemic diseases, poor oral hygiene etc. must be considered. Management of stress is an important factor. In this review article various oral lesions are discussed in COVID-19 infection states in detail. The importance of earliest diagnosis of oral lesions is to be kept in mind to prevent further complications.
