ABSTRACT

Development of the STEM curriculum played a key role in economic development because it enabled the production of well-qualified production from schools. This development extensively depends on the demonstration of competence in key knowledge areas such as science, technology, engineering, and mathematics disciplines (Dhurumraj et al., 2020). Sustainable STEM education is still in its early stage of development in higher education. Although the COVID-19 pandemic presented unprecedented challenges to this fairly new field, it also helped increase the focus on elements of the Fourth Industrial Revolution, concerning education (Sobrosa Neto et al., 2020). This study systematically reviewed the current articles (n=15) of STEM education in higher education during COVID-19. Results indicated that Faculty members considered the transition from face-to-face to web-based programs effective even though they faced several challenges. Further investigation showed that the application of STEM online learning has helped to increase students’ creativity and the rate of STEM research by both students and faculty members. Comparative studies about the differences between the two modes of STEM learning in higher education programs (face-to-face, online) and how they can be harmonized is suggested. © 2022 by the authors;licensee Modestum.

ABSTRACT

Studies have shown that contacting with beautiful natural environments improves people's mood and reduces pressure. Environments that facilitate physical and psychological recovery are called restorative environments. Compared with other types of environments, natural sightseeing resorts have the most prominent restorative value, and have attracted the attention of numerous scholars. Tourists' perceived restorative qualities have gradually become a frontier of environmental psychology and tourism studies. However, studies of tourists' perceived restorative qualities are still in their infancy, with limited results regarding various aspects. For example, the development of a tourist restorative perception scale, and the antecedent factors underlying tourists' perceived restorative qualities. Few studies can be found investigating the relationship between tourists' perceived restorative qualities and their post-visit behavioral intention. Post-visit behavioral intention is of great significance in terms of guiding the management and marketing of tourist destinations. The COVID-19 pandemic has led to a sharp decline in the willingness of potential tourists to travel. As consumption by tourists shifts toward the pursuit of greenness and health during the continuation of the epidenic, further improving their satisfaction, stimulating word-ofmouth promotion, and strengthening tourist loyalty through physical and mental recovery experience to enable tourist destinations to enhance their competitive advantage, then to revitalize, has become an issue worthy of investigation. By maintaining close contact with destination environment, tourists can effectively enhance their physical and mental functions, produce a sense of satisfaction and increase positive behavioral intention. Thus, it is important to explore the mechanism underlying tourists' perceived restorative qualities to aid product innovation and marketing promotion, and promote the sustainable development of tourist destinations. On the basis of previous studies, we used attention restoration theory to analyze the impact of tourists' perceived restorative qualities. On the basis of the Mehrabian-Rusell framework, we developed a theoretical integrated model including four constructs:Tourists' perceived restorative qualities, tourist satisfaction, post-visit behavioral intention and tourist involvement. The model was tested using structural equation modeling. All constructs were measured using selfreported, multiple-item scales adopted from previous studies. Data were collected from Kanas, a well known nature-based tourist destination located in Altay, China. The questionnaires were distributed by a group of five people on 1-7 August 2019. A total of 600 questionnaires were distributed, and 547 completed questionnaires were returned. The results were as follows:(1) Tourists' functional perceived restorative qualities(coherence, novelty) directly and positively affect their emotional perceived restorative qualities(fascination, compatibility, escape);(2) Novelty and escape are key factors affecting post-visit behavioral intention, and fascination and compatibility affect post-visit behavioral intention through satisfaction. Furthermore, novelty, compatibility and satisfaction have a multiple chain-mediating effect on the relationship between coherence and post-visit behavioral intention, while compatibility and satisfaction have a multiple chain-mediating effect on the relationship between novelty and post-visit behavioral intention;(3) The influence of fascination and compatibility on satisfaction is positively regulated by tourist involvement;and(4) The effect of tourists' perceived restorative qualities on their post-visit behavioral intention exhibited a three-stage"environmental stimuli perception-emotion-intention"transmission mechanism.In this study, we analyzes the benefits of tourists' perceived restorative qualities, which provides important references for tourism destination managers in relation to environmental optimization, marketing and brand building.

ABSTRACT

The COVID-19 pandemic radically changed people’s lives and the state of affairs in all spheres of life and transformed environmental ideas, social problems at the micro and macroeconomic levels, and the market mechanism to maintain economic justice. The pandemic consequences have exacerbated individualism, intersectionality, diversity, and inclusiveness issues. Disproportionate risks and worsened outlooks have been observed for socially and economically vulnerable groups. The present cross-cultural study discusses the content of social media on the COVID-19 perception by Spanish, German, and Russian-speaking actors, applying a multimodal approach and using neural network technologies and text analyses. The data analysis made it possible to identify common and distinctive features of communicative actors’ perception of various aspects of the COVID-19 pandemic. With the identity of explicitly expressed issues, the implicit information for the three types of users was significantly different, reflected in the dissimilar course and evolution of the COVID-19 pandemic around the world, shedding light on their cultural and political reasons. © 2022 Universidad de La Sabana.

ABSTRACT

Urban green spaces have shown to be beneficial for the physical and mental wellbeing of the general population—which particularly holds true during an unprecedented, stressful situation such as the COVID-19 pandemic. In urban settings characterized by structural inequality, scarce access to green spaces in a neighborhood can affect the wellbeing of its inhabitants and lower overall resilience of a community. Assuming that the effects of confinement and working from home produce an increased demand for recreational and sports activities, this paper looks to assess the level of preparedness and accessibility of green spaces during the COVID-19 pandemic, considering individual and public measures to avoid contagion. The assessment is carried out through an online exploratory survey and accessibility calculations that are applied to two Chilean cities with a Mediterranean climate, Talca and Chillán. The study considers the quality of green spaces based on (i) official statistics and (ii) a questionnaire directed toward residents. We found that high-quality urban green spaces are accessible to residents of both cities, but rather limited in December 2020 due to low levels of preparedness. Considering the qualities of existing urban green spaces allows for a more precise estimate of their contribution to the wellbeing of neighborhoods, and consequently facilitates better recommendations for urban plans and policies.

ABSTRACT

The fulfillment of belonging needs underlies a variety of behaviors. In order to understand how social needs unmet during maturation shape everyday life, we examined social motivation and cognition in peripubertal rats, as a rodent model of adolescence, subjected to social isolation (SI) during early and early-to-mid adolescence. The behavioral correlates of social orientation (social space preference), sociability (preference for social over non-social novelty), and social novelty preference (SNP) were examined in group-housed (GH) and single-housed (SH) rats in a 3-chamber test. The response to social odors was examined to gain insight into the developmental role of social odors in motivated social behavior. Differentiation between appetitive (number of visits/approaches) and consummatory (exploratory time) aspects of motivated social behavior was done to determine which facet of social motivation characterizes maturation when social needs are met, and which dominates when social needs are unsatisfied. The SI-sensitive parvalbumin-expressing interneurons (PVI) in the hippocampus were examined using immunohistochemistry. The main findings are: 1) in GH rats, the preference for social space is not evident regardless of animals' age, while sociability becomes apparent in mid-adolescence strictly through consummatory behavior, along with complete SNP (appetitive, consummatory);2) SH promotes staying in a social chamber/space regardless of animals' age and produces an appetitive preference for it only in early-adolescent animals;3) SH promotes sociability (appetitive, consummatory) regardless of animals' age and prevents the SNP;4) the preference for a social odor is displayed in all the groups through consummatory behavior, while appetitive behavior is evident only in SH rats;5) the response to social odors does not commensurate directly to the response to conspecifics;6) SH does not influence PVI in the hippocampus, except in the case of early-adolescence when a transient decrease in the dentate gyrus is observed. These results accentuate the developmental complexity of social motivation and cognition, and the power of SI in adolescence to infringe social maturation at different functional levels, promoting appetitive behavior toward peers overall but harming the interest for social novelty. The findings emphasize the importance of the fulfillment of basic social needs in the navigation through the social world.

ABSTRACT

The present study examined the association between risk perception and travel satisfaction related to the use of public transport (PT) during COVID-19 pandemic in Turin, Italy. A total of 448 PT users took part in an online survey conducted from January to March 2021. It investigated safety and risk perception related to the use of PT, and the users' subjective experience, measured through the Satisfaction with Travel Scale (STS). These perceptions were compared for three time scenarios: before the pandemic, during the pandemic, and in the future at the end of the pandemic emergency. Results showed that COVID-19 influenced respondents risk perception both during the pandemic and in their projections about the future, especially for females. The risk of contagion from COVID-19 is perceived as higher inside a PT vehicle than in the adjacent/waiting spaces. Regarding travel satisfaction, the overall scores of the STS indicated that the pandemic has impacted reported well-being while travelling, both now and in the future. The dimension of activation shifted towards the negative pole and did not indicate a return to risk perception before the pandemic levels at the end of the crisis (especially for females). Respondents reported a significant decrease in their level of pleasure and satisfaction during the pandemic, but expect that in the future these levels will go back to the levels previously experienced. Regarding travel satisfaction, PT users aged 36 to 50 years reported the highest level of satisfaction, while younger users (18 to 35 years) reported the lowest degree of satisfaction in all three time scenarios. Overall, the results clearly pinpoint that health-related perceived risk is becoming a key determinant for PT use. Within this context, different dimensions of travel satisfaction proved to be impacted differently by the pandemic, for both current and future scenarios.

ABSTRACT

Racial and ethnic minority and lower-income groups are disproportionately affected by environmental hazards and suffer worse health outcomes than other groups in the United States. Relative to whites and higher-income groups, racial-ethnic minority and lower-income Americans also frequently express greater concern about high-profile global environmental threats like climate change, but they are widely misperceived as being less concerned about these issues than white and higher-income Americans. We use new survey research to explore public perceptions of COVID-19—another global threat marked by substantial racial, ethnic, and class disparities—finding a distinct pattern of misperceptions regarding groups’ concerns. We then discuss how these misperceptions represent a unique form of social misinformation that may pose a threat to science and undermine the cooperation and trust needed to address collective problems.

ABSTRACT

Purpose: Since the emergence of a coronavirus disease (2019-nCoV) in December 2019, the whole world is in a state of chaos. Isolation strategy with quarantine is a useful model in controlling transmission and rapid spread. As a result, people remained at home and disrupted their outside daily activities. It led to the closure of educational institutes, which is a source of many students to cope with numerous personal and familial issues. This study aims to focus on exploring the relationships and potential mediational pathways between mental health problems, illness perception, anxiety and depression disorders. Design/methodology/approach: The study incorporated snowball sampling techniques through a cross-sectional, Web-based survey and recruited 500 students from different universities of twin cities, Rawalpindi and Islamabad from March 23 to April 15, 2020, during the coronavirus outbreak lockdown. The study used four instruments, Beck Depression Scale, Beck Anxiety Inventory, Revised Illness Perception Questionnaire and The Warwick-Edinburgh Mental Well-being Scale for assessing depression, anxiety, illness perception and mental health disorders. Findings: The findings indicated normal (43.2%), mild (20.5%), moderate (13.6%) and severe (22.7%) levels of anxiety prevalence in students. Results specified a normal (65.9%), mild (9.10%), moderate (9.12%) and severe (15.90%) depression prevalence and findings stipulated that anxiety disorder prevalence was higher than depression disorder. The correlational results specified a negative and significant relationship between mental health, illness perception, anxiety and depression symptoms. The multiple regression analysis stated that anxiety and depression disorders mediated the relationship between mental health and present illness perception. The perception of illness exhibited a relation to depression and anxiety disorders. Originality/value: The study proposed a model to address mental health problems during the lockdown. The (2019-nCoV) illness perception developed mental disorders, including anxiety and depression, which has declined individuals' mental health. There is an urgent need for ongoing clinical examination and management to address psychological disorders and findings suggest assessing mental health to combatting the pandemic worldwide. Findings recommend developing strategies to promote mental health-care facilities during COVID-19 wide-ranging disasters. These results highlight the impending importance of devising strategies to treat mental health problems. (PsycInfo Database Record (c) 2022 APA, all rights reserved)

ABSTRACT

Purpose>The COVID-19 pandemic has brought about a contingent shift to remote working and learning worldwide. However, little is known regarding the impact of this shift on internships. Moreover, much of the available literature studies on internships are focused largely on perceptions by students, less so by supervisors. This paper describes the impact of COVID-19 on public health (PH) internships and examines interns' and supervisors' perspectives on their experiences in internships before and during the pandemic.Design/methodology/approach>A cross-sectional study design was conducted on two cohorts of undergraduate students and their supervisors in Singapore. Participants were surveyed using questionnaires with both close-ended and open-ended questions about various aspects of the internship experience. Data were triangulated from these surveys and module evaluation reports, and analyzed quantitatively and qualitatively.Findings>COVID-19 disrupted internships significantly, with a reduction in the number of placements offered and necessary changes to the internship scope. Overall, the internship experience has been positive. Supervisors and e-interns reported high levels of satisfaction and documented learning gains such as the development of technical skills and soft skills unique to remote work.Originality/value>The study findings fill current gaps in the literature on supervisor perceptions and internship experiences during COVID-19. Recommendations are proposed to optimize e-internships, a potentially authentic workplace in the post-COVID era.

ABSTRACT

Due to the recent COVID-19 pandemic, most of the universities across United States limited the amount of in person instruction. This brought a challenging situation in animal sciences courses that required laboratory sessions and hands-on experiences. There is not a real solution to replace the in-person labs, however several approaches can be implemented to overcome some of the challenges for laboratory sessions. Some of the on-line approaches implemented in an introductory class of Animal Sciences during the semester of spring and fall 2020 were live (synchronous) laboratory sessions (live interactions with animals, pre-recorded sessions of the laboratory session, and 360-degree videos of tours to the farms). The main objective of the present report is to assess the usefulness and feedback of these approaches to teach laboratory sessions to an undergraduate introductory animal science course. The official (Blue) university student responses in the course were used to determine the perception and feedback to these approaches. A total of 123 responses were recorded (Spring: 42/96, Fall: 81/174). Overall, no significant differences were observed in terms of the student perception. Overall, the responses were positive toward the laboratory sessions even in an online environment. During the spring semester 40/42 (95%), whereas in 72/81 (88%) strongly agree/mildly agree that labs help them to learn respectively. In terms of the videos used in class and labs, during the spring semester 35/41 (85%) and 68/81 (83%) strongly agree/mildly agree that labs help them to learn. In summary, the new reality due to COVID pandemic is very challenging for Animal Science courses that have laboratory sessions that involves hands-on experiences. Despite this, in conclusion some approaches can be implemented to still provide meaningful experiences to undergraduate students to support their learning and engagement in the introductory animal science course.

ABSTRACT

Consumer behaviour is the key to the success of a business. In the current economic context, it is the survival of a business. The novel coronavirus has created an incredibly difficult situation in the business climate today. Business has faced lot of new challenges like closure of import and export due to international boarder close, shutdown of brick and mortar businesses, big malls and home isolation of people. Many companies faced closures, with many employees laid off and many were given less salary. Our consumption pattern also changed on a massive scale. The availability of goods was the main concern, which led to some panic buying of essential items, in bulk. Consumers’ behaviour and perception got changed, as an impact of this unprecedented pandemic. This paper, in this context, aims to analyse the perception, attitude, sentiments and buying behaviour of consumers of Odisha during the COVID-19 lockdown period (i.e. from March to October, 2020). Further, it aims to study the change of media consumption habits of the consumers. This study tries to infer how COVID-19 lockdown changed the behaviour of consumers in Odisha over 8 months and what would be future implications. © 2022, The Author(s), under exclusive license to Springer Nature Singapore Pte Ltd.

ABSTRACT

COVID-19 has made a big impact worldwide due to its tendency to rapidly spread. All nations across the world have taken all possible measures to minimize its effect and to bring life back to normal. Vaccine for COVID-19 has come into the market but the hunt for a better vaccine is still going on. The community is showing mixed responses towards the acceptance of the vaccine despite the unprecedented efforts that are being taken globally to develop a vaccine against COVID-19. Since the advent of COVID-19 and till the vaccine is being given to the people, social media has been on the forefront of spreading news related to COVID-19 and vaccination. Social media has created the perception among people related to every situation during the pandemic, therefore the current study reveals the impact of social media on people and their reaction to the situation. The objective of the study was to assess the influence of social media with respect to the awareness and behavioural change among people and also examining the influence on acceptance of the vaccine. The data was collected from social media platforms and using quantitative methods. It was suggested that social media can encourage positive behavioural changes and it can also be used as powerful media tool to address social concern and to remove social dogma among people with regards to vaccination. © 2022, The Author(s), under exclusive license to Springer Nature Singapore Pte Ltd.

ABSTRACT

The COVID-19 pandemic forced many schools to switch to online classes. Although there has been a movement to return to face-to-face classes since then, many schools are still struggling to ensure safety during classes and subsequent examinations in a face-to-face environment. In this study, we attempted to visualize the relationship between class usage and building air conditioning management by installing CO2 sensors at fixed points in classrooms and also applied them to environmental monitoring during examinations to grasp the risks in real time and provide a response. © 2022, IFIP International Federation for Information Processing.

ABSTRACT

BACKGROUND: The characteristics of the transmission of SARS-CoV-2 virus increased the need to implement prevention measures, in order to avoid its spread;therefore, there is an interest in the risk perception and an intention in people to adopt protective measures against COVID-19. OBJECTIVE: To show the causal factors that contribute to a high/low perception of risk during the COVID-19 pandemic. MATERIAL AND METHODS: A quantitative, analytical and explanatory exploratory study was carried out with a crosssectional design. To collect data, a self-access survey was designed, using the Dimensional Assessment of Perceived Risk procedure, based on the psychometric paradigm. For data analysis, the classification tree method was utilized. RESULTS: The descriptive analysis indicated that the surveyed population had a concern about the pandemic of 3.8 on a scale ranging from 1 to 5, which shows a medium-high perception of COVID-19 risk;however, respondents underestimated their personal risk (vulnerability) in relation to that of others. The classification tree analysis showed that the independent variables that contribute directly to the global perception of risk are the severity of the pandemic, vulnerability and catastrophic power. CONCLUSIONS: It was found a positive effect: The greater perception of severity, and susceptibility to acquiring the virus, the more taking of preventive measures.

ABSTRACT

BACKGROUND: In order to reduce COVID-19 transmission and protect healthcare workers, the outpatient departments (OPDs) in many hospitals worldwide were closed down in the early days of the pandemic. Patients being managed for chronic medical illnesses who subsequently suffered reduced access to healthcare have been described as "the patients left behind". AIM: The study aimed at assessing the impact of the closure of the Medical OPD in University of Ilorin Teaching Hospital (UITH) on the health and perceived well-being of patients with chronic medical illnesses. METHODS: A cross-sectional study of 180 patients with chronic medical illnesses attending the MOPD in UITH. RESULTS: Mean age of participants was 50.2+/-18.2years, 92 (51.1%) were male, median duration of attending MOPD was 21 months (IQR 12-36). 92 patients (51.1%) perceived a negative affectation of their well-being by the closure of MOPD. Being >50 years was associated with a perception of negative affectation of well-being (P=0.042). 140 patients (77.8%) had clinic appointments that fell within the period under review. 67(69.3%) of the 97 patients who had medical complaints during the period could not reach a doctor and this was associated with a perception of negative affectation of their wellbeing. The commonest action they took was to do nothing (28.3%), three (4.5%) resorted to herbal concoctions. 19 (29.9%) felt their complaints were urgent. CONCLUSION: Our study identifies that patients with chronic medical illness are potential victims of COVID-19 related disruption of healthcare services. Healthcare managers in Nigeria must develop alternatives such as telemedicine that sustain face-to-face medical interaction during eventualities.

ABSTRACT

This study examines the high-risk group of individuals age 65 and over who most frequently experience the negative consequences of Covid-19. We review their communicative needs and expectations, knowledge and information sources, and risk information and knowledge patterns. We conducted semi-structured interviews with 47 people aged 65 and over residing in Ankara. We evaluated our results in the context of The Social Amplification of Risk Framework, considering the major communication stations disseminating risk information. We found that during the Covid-19 pandemic, individuals aged 65 and over accessed risk information through new media and traditional media, and interpersonal communication, especially with close family and children, served as a primary information source during the pandemic. The trust factor, particularly regarding medical expertise, was an essential criterion in evaluating information. The communicative needs and expectations changed for this high-risk group. The need for improved digital communication capabilities become apparent during the pandemic crisis. Suggestions that consider public perspectives and risk perceptions while incorporating the relationship between risks and communication processes may contribute to structuring impactful risk communication activities.Alternate : Bu çalışmada, Covid-19 pandemisinde hastalığın olumsuz sonuçlarını ağır derecede yaşama ihtimallerinin yüksekliği nedeniyle öncelikli risk gruplarından biri olarak tanımlanan 65 yaş ve üzeri kişilerin iletişimsel ihtiyaçları, beklentileri, bilgi ve enformasyon kaynakları ve risk enformasyonunu ve bilgilerini değerlendirme biçimleri ele alınmaktadır. Çalışma kapsamında Ankara’da ikamet eden 65 yaş ve üzeri toplam 47 kişiyle yarı yapılandırılmış görüşmeler gerçekleştirilmiştir. Elde edilen bulgular, Riskin Sosyal Artırımı Kuramsal Çerçevesi bağlamında, risk enformasyonunun iletimindeki temel iletişim uğrakları dikkate alınarak değerlendirilmiştir. 65 yaş ve üzeri bireylerin Covid-19 pandemisi sürecinde risklere ilişkin enformasyona geleneksel medyanın yanı sıra yeni medya aracılığı ile de ulaştıkları;kişilerarası iletişimin bu süreçte temel bilgi kaynaklarından biri olarak işlev gördüğü;yakın aile ve özellikle çocukların Covid-19 pandemisiyle ilgili bilgilenme süreçlerinde ayrıcalıklı bir yeri olduğunu belirlenmiştir. Enformasyonun değerlendirilmesinde güven unsurunun temel kriter olarak dikkate alındığı ve tıp alanındaki uzmanlıklara daha yüksek güven atfedildiği ortaya konmuştur. Ayrıca iletişimsel ihtiyaçların ve beklentilerin pandemi süreci içerisinde değişime uğradığı anlaşılmıştır. Pandemi döneminde, dijital iletişim yetkinliklerin geliştirilmesi ihtiyacı belirginlik kazanmıştır. Görüşmelerden elde edilen bulgulardan hareketle, kamuların perspektifini ve risk algısını gözeten;risklerin iletişimsel süreçlerle bağlantısını dikkate alan etkili risk iletişimi çalışmalarının yapılandırılabilmesine katkıda bulunabilecek öneriler sunulmuştur.

ABSTRACT

With the rise in high quality displays and cameras following the mainstream adoption of smartphones, image quality has become an essential aspect of engaging and attracting consumers. In the case of smartphones, the bar raises with release of every new generation. There are many factors affecting image quality such as sharpness, image noise or non-uniformity, and geometric distortion, but it is fair to say that color plays a vital role in the perceived quality of an image. Colors not only spark emotions and engage a user but also decide the likability of a certain image. Over the past few years computational photography techniques have become a major differentiating factor between camera manufacturers. These techniques are used to enhance certain features of an image such that it is more pleasing to the viewer. It is important to understand better the perceived and preferred image quality for pictures and to develop a procedure for evaluating them as a part of the camera/display development and design process.This dissertation focuses on exploring such preferred color image renderings using different methodologies of perceptual assessments. We focus on common scenes that contains memory objects such as grass, sky, skin tone, beach sand and food items. In particular, we also focus on white balance preference of an image which controls the appearance of the object in the scene under different illumination. The ultimate goal of this dissertation is to address how we perceive color quality and to develop procedures for its evaluation, and to assess preferred color image rendering. These results can be used to help design better cameras and displays by improving color image quality.In order to achieve the goal of the dissertation, we focus on investigating the preferred rendering of common scenes that contains memory objects, scenes captured under different illumination - controlled and uncontrolled light settings. First we address how we perceive memory colors, with and without pictorial scene content. Then we study the impact of different texture types on these memory colors, along with understanding the relationship between memory color and color quality preference. This dissertation also addresses the color quality of video conference calls using virtual backgrounds, which has been a common means of communication since COVID19 pandemic. In particular, it focuses on the preferred color balance for images with a foreground model against a virtual background. To further investigate the white balance preference settings, we assessed images where the foreground, containing a person, is illuminated by a different correlated color temperature (CCT) than the background, which includes several targets. Models having different skin tones were used. (PsycInfo Database Record (c) 2022 APA, all rights reserved)

ABSTRACT

Aim: The knowledge of viral characteristics in addition immune reply to severe respiratory disorder (Sars Syndrome Coronavirus 2 (SARS-CoV-2) contamination still has significant gaps. Methods: In a retrospective longitudinal cohort analysis of 140 cases having PCR-established SARS-CoV-2 disease, researchers analyzed those parameters and demonstrated their correlation with symptom manifestations (mean age, 44 years;54 percent male;48 percent through comorbidities). Breathing models (n = 76) remained obtained for viral culture, serum specimens (n = 32) for IgM/IgG levels, and plasma samples (n = 82) for inflammatory cytokines and chemokines. The illness burden remained connected to the findings of viral culture, serologic tests, also immunological markers. Results: Fifty-eight (58%) cases established viral pneumonia, including 22 (18%) requiring supplementary oxygen and 14 (11%) requiring invasive mechanical ventilation. Twenty of the 77 individuals were positive for viral culture from respiratory samples (24 percent). When the PCR cycle threshold (Ct) value remained more than 31 or greater than 15 days following indication onset, no virus was recovered. Seroconversion happened at a median (IQR) of 13.6 (10-20) days for IgM and 16.1 (14-22) days for IgG;56/63 patients (88.2 percent) seroconverted on day 15 or later. Health hazard appeared linked to quicker seroconversion as well as greater peak IgM and IgG levels. Conclusion: Researchers discovered that viral viability significantly related having such a lower PCR Ct charge in the initial stages of disease. The seriousness of the illness was linked to a greater antibody level. Overcharged pro-inflammatory immune markers provide marks for host-directed immunotherapy, that would have been investigated in randomized precise studies.

ABSTRACT

Objectives: The study aimed to examine COVID-19 knowledge among the general public in Pakistan, to review their attitudes and views regarding the fast epidemic. Study Design: Descriptive cross-sectional study. Duration of Study: June-July 2020. Methodology: A total of 679 respondents included. The questionnaires comprised of the following basic themes: basic demography, general & basic clinical/medical knowledge, attitudes, awareness, perceptions as well as a sense of prevention regarding COVID-19. Results: The majority (75.5%) of the respondents were from Punjab province. Around half (54.5%) of the respondents had heard about the COVID-19 infection through different social media. The majority were 28.4% medical students. The majority of the respondents (80-95%) selected correct answers from the given choices for the questions related to some clinical knowledge. More than half of people (59-64%) think positively that COVID-19 will successfully be controlled and Pakistan will be successful in winning this battle of the pandemic. 61% were afraid of COVID-19 as it is highly contagious disease (37.7%). Around 60% always covered their noses and mouths while sneezing and coughing. Conclusion: The people must have a thorough understanding of COVID-19 to successfully execute COVID-19 prevention strategies. Although we found enough knowledge, favorable perspectives, and readiness to follow SOPs, we believe that additional preventative and cautious attitudes, as well as awareness, are needed.
