ABSTRACT

The teaching of automation is increasingly present in the industry, through increasingly aggregating and complete platforms. Automation teaching/learning faces several limitations. On the one hand, teaching automation using automata is done in laboratories whose didactic applications rarely replicate industrial applications. On the other hand, students' difficulties in accessing these spaces are often limited to the time allocated to each laboratory class, and it is often not possible to repeat assignments or work variants. It should be noted that the difficulty of accessibility for working students or students with COVID restrictions has a lot of impact. Thus, it would be important for a student to have access to an automation bench that replicates the needs of the industry and that includes remote access. The present work presents the development of a didactic workbench to support the teaching / learning of automation, with an industrial design and with the possibility of remote access. © 2022 IEEE.

ABSTRACT

Can presidential messages influence public opinion? The scholarship shows that common features in developed democracies such as fragmented audiences and partisan reasoning tend to limit the persuasive effects of the bully pulpit. In this article, we argue that the effectiveness of the presidential rhetoric is context dependent. Presidents will be the most likely to persuade public opinion when they seek to break consensus by using messages that activate defection among their supporters. To examine this framework, we focus on the setting of the COVID-19 pandemic in Brazil, where the outbreak was initially a valence issue, but quickly it became a divisive matter among the public. We use a survey experiment conducted days before the President Bolsonaro's national televised address to show that cueing subjects with one of his earlier denialist remarks about the outbreak polarized opinions. We then use Bayesian change-point models to demonstrate how his major televised speeches affected daily trends in online searches related to the pandemic during the first and the most crucial weeks of the outbreak. The findings shed light on the circumstances in which presidential influence can not only be most powerful, but also most harmful.

ABSTRACT

SARS-CoV-2 has affected people worldwide as the causative agent of COVID-19. The virus is related to the highly lethal SARS-CoV-1 responsible for the 2002–2003 SARS outbreak in Asia. Research is ongoing to understand why both viruses have different spreading capacities and mortality rates. Like other beta coronaviruses, RNA-RNA interactions occur between different parts of the viral genomic RNA, resulting in discontinuous transcription and production of various sub-genomic RNAs. These sub-genomic RNAs are then translated into other viral proteins. In this work, we performed a comparative analysis for novel long-range RNA-RNA interactions that may involve the Spike region. Comparing in-silico fragment-based predictions between reference sequences of SARS-CoV-1 and SARS-CoV-2 revealed several predictions amongst which a thermodynamically stable long-range RNA-RNA interaction between (23660–23703 Spike) and (28025–28060 ORF8) unique to SARS-CoV-2 was observed. The patterns of sequence variation using data gathered worldwide further supported the predicted stability of the sub-interacting region (23679–23690 Spike) and (28031–28042 ORF8). Such RNA-RNA interactions can potentially impact viral life cycle including sub-genomic RNA production rates.

ABSTRACT

The high numbers of COVID-19 cases and deaths in Brazil have made Latin America an epicentre of the pandemic. SARS-CoV-2 established sustained transmission in Brazil early in the pandemic, but important gaps remain in our understanding of virus transmission dynamics at a national scale. We use 17,135 near-complete genomes sampled from 27 Brazilian states and bordering country Paraguay. From March to November 2020, we detected co-circulation of multiple viral lineages that were linked to multiple importations (predominantly from Europe). After November 2020, we detected large, local transmission clusters within the country. In the absence of effective restriction measures, the epidemic progressed, and in January 2021 there was emergence and onward spread, both within and abroad, of variants of concern and variants under monitoring, including Gamma (P.1) and Zeta (P.2). We also characterized a genomic overview of the epidemic in Paraguay and detected evidence of importation of SARS-CoV-2 ancestor lineages and variants of concern from Brazil. Our findings show that genomic surveillance in Brazil enabled assessment of the real-time spread of emerging SARS-CoV-2 variants.

ABSTRACT

Background: Acute Transverse Myelitis (ATM) is a very uncommon neurological syndrome, characterized by acute or subacute spinal cord dysfunction that can lead to paresthesias, sensory/autonomic impairment and paralysis. The aetiology is often unclear, but infectious, para-infectious, systemic autoimmune diseases, paraneoplastic, ischemic diseases and drugs are potential causes. Vaccine administration can also trigger an immune response and induce an autoimmune response;however, ATM has rarely been reported as a complication of COVID-19 infections or vaccination. The treatment mainly consists of steroids and plasmapheresis, which often reverses any neurologic symptoms. The therapeutic plasmapheresis is a highly complex procedure. It separates the patient's blood components replacing the plasma removed by solution that can be fresh frozen plasma or albumin, allowing the removal of the autoantibody, immune complex, lipoprotein or endotoxin that's causing the pathology. Aims: Clinical case report. Methods: A 46-year-old male patient, with personal history of hypertension and obesity, 3 weeks after COVID-19 vaccination, presented to the emergency department due to urinary complaints (urgency and pollakiuria), progressive numbness, paresthesias and decreased muscle strength in the lower limbs and decreased sensibility in the perineal region. Physical examination revealed total gait disability, decreased sensation and strength in the right lower limb, loss of sensation and plegia in the left lower limb and urinary incontinence. Initial laboratory workup and CT imaging of the brain, cervical, dorsal and lumbar spine were normal. The patient was admitted to Neurology internment for further study and treatment. During hospitalization, lumbar puncture and MRI of the dorsal and lumbosacral neuraxis were performed, but only allowed us to exclude infectious and compressive etiologies. The inflammatory aetiology was assumed as the most probable, so acute therapy with pulses of methylprednisolone was initiated. In the remaining study, weakly positive anti-MOG (Myelin Oligodendrocyte Glycoprotein) antibodies were detected in the serum. Therapeutic plasmapheresis using a cell separator (which use centrifugal force to separate components according to their density) was proposed as additional therapy. Seven sessions were performed without intercurrences. Results: During acute therapy, there was a partial improvement in sensitivity and strength in lower limbs. The patient started a rehabilitation program with favourable neurological recovery. At the time of hospital discharge, he still needed crutch support for walking and had muscle strength grade 4-/5 bilaterally. Summary/Conclusions: Although the patient maintained some functional limitation and there was not a complete resolution of the neurological symptoms, he showed a good response to acute therapy. The plasmapheresis, by permitting the antibody to be removed faster than would occur by its endogenous clearance, proved to be fundamental in the clinical recovery of the patient. No relationship between COVID-19 vaccination and the event was established.

ABSTRACT

Video coding technology and standards have largely shaped the current world in many domains, notably personal communications and entertainment, as demonstrated during recent COVID-19 times. AI-based multimedia tools already have a major impact in many computer vision tasks, even reaching above human performance, and are now arriving to multimedia coding. In this context, this paper offers one of the first extensive benchmarking of deep learning-based video coding solutions regarding the most powerful and optimized conventional video coding standard, the Versatile Video Coding standard, under the solid, meaningful, and extensive JVET common test conditions. This study will allow the video coding research community to know the current status quo in this emerging ‘battle’ between learning-based and conventional video coding solutions and better design future developments. © 2022 SPIE.

ABSTRACT

This study aims to analyze the dynamics of the interface policies with food and nutrition in the context of the pandemic and its interferences in the scenario of Food and Nutrition Insecurity (InSAN). It is a documentary research in which it was listed as primary sources of data, documents available in institutional websites and texts published in journalistic media. Thus, it included: legislation and digital journalistic texts. After the exploratory reading of the documents, the following axes of analysis were delimited: Impacts of Constitutional Amendment no95/2016 in the current health crisis;food and nutrition policies during the pandemic and income transfer and unemployment programs. The results show that the current sanitary crisis aggravates the InSAN scenario, as the assistance actions are insufficient to attend the population in periods of public calamity. In addition to this scenario, the previous pandemic context, in which the necro politics of suppression of rights contributed to the worsening of social vulnerabilities, including the lack of access to food.

ABSTRACT

BACKGROUND: The COVID-19 pandemic led to dramatic threats to health and social life. Study objectives - develop a prediction model leveraging subsample of known Patient/Controls and evaluate the relationship of predicted mental health status to clinical outcome measures and pandemic-related psychological and behavioral responses during lockdown (spring/summer 2020). METHODS: Online cohort study conducted by National Institute of Mental Health Intramural Research Program. Convenience sample of English-speaking adults (enrolled 4/4-5/16/20;n=1,992). Enrollment measures: demographics, clinical history, functional status, psychiatric and family history, alcohol/drug use. Outcome measures (enrollment and q2 weeks/6 months): distress, loneliness, mental health symptoms, and COVID-19 survey. NIMH IRP Patient/Controls survey responses informed assignment of Patient Probability Scores (PPS) for all participants. Regression models analyzed the relationship between PPS and outcome measures. OUTCOMES: Mean age 46.0 (+/-14.7), female (82.4%), white (88.9 %). PPS correlated with distress, loneliness, depression, and mental health factors. PPS associated with negative psychological responses to COVID-19. Worry about mental health (OR 1.46) exceeded worry about physical health (OR 1.13). PPS not associated with adherence to social distancing guidelines but was with stress related to social distancing and worries about infection of self/others. INTERPRETATION: Mental health status (PPS) was associated with concurrent clinical ratings and COVID-specific negative responses. A focus on mental health during the pandemic is warranted, especially among those with mental health vulnerabilities. We will include PPS when conducting longitudinal analyses of mental health trajectories and risk and resilience factors that may account for differing clinical outcomes. Funding: Nimh (ziamh002922);nccih (ziaat000030).

ABSTRACT

This article aims to analyze the discursive practices present in the training of teachers in the state of Rio Grande do Sul (Brasil), during the pandemic of Covid-19. How the government organized school activities (online), and how teaching, and education was guided by the financial logic applied in such as the accountability of school success to individuals (students and teachers). Based on the concept of Human Capital, it analyzes the relation between the ordering principles of neoliberal discourse with the digitization practices of public education. For this, the research uses concepts from Foucault's theory of discursive studies and biopolitical population governance.

ABSTRACT

People turn to social media to express their opinion towards different topics and issues. This makes social media a valuable resource for mining public opinion. Stance detection is an approach to analyzing social media users’ content to determine public opinion. In this paper, we present a replicable methodology for coding tweets for stance detection towards the COVID-19 vaccination. The methodology includes a codebook for coding the stance towards COVID-19 vaccination and 2 approaches to sampling Twitter data for manual coding: keywords and hashtags. The codebook provides a template for other researchers to code social media data for stance towards vaccination. Our analysis of the results from 2 sampling approaches shows that sampling with hashtags leads to high inter-coder agreement. We analyze the stance and compare it with the results from sentiment analysis on the same dataset to highlight the distinction of our methodology for stance analysis when compared to sentiment analysis towards vaccination. The major contributions of this paper are: a replicable methodology for annotating stance towards COVID-19 vaccination with a codebook and dataset, and a comparison of sampling Twitter data with keywords and hashtags on the inter-coder agreement along with the resulting distribution of stance. © 2022, The Author(s), under exclusive license to Springer Nature Switzerland AG.

ABSTRACT

Brazil has experienced some of the highest numbers of COVID-19 cases and deaths globally and from May 2021 made Latin America a pandemic epicenter. Although SARS-CoV-2 established sustained transmission in Brazil early in the pandemic, important gaps remain in our understanding of virus transmission dynamics at the national scale. Here, we describe the genomic epidemiology of SARS-CoV-2 using near-full genomes sampled from 27 Brazilian states and a bordering country - Paraguay. We show that the early stage of the pandemic in Brazil was characterised by the co-circulation of multiple viral lineages, linked to multiple importations predominantly from Europe, and subsequently characterized by large local transmission clusters. As the epidemic progressed under an absence of effective restriction measures, there was a local emergence and onward international spread of Variants of Concern (VOC) and Variants Under Monitoring (VUM), including Gamma (P.1) and Zeta (P.2). In addition, we provide a preliminary genomic overview of the epidemic in Paraguay, showing evidence of importation from Brazil. These data reinforce the usefulness and need for the implementation of widespread genomic surveillance in South America as a toolkit for pandemic monitoring that provides a means to follow the real-time spread of emerging SARS-CoV-2 variants with possible implications for public health and immunization strategies.

ABSTRACT

This study presents the experience of using Arduino and the platform Tinkercard for developing programming competencies in first-year students at the Continental University of Huancayo (Peru). The study is conducted online during the COVID-19 pandemic by using a simulator. The development of programming competencies is a fundamental and essential milestone for students enrolled in systems engineering, information science, computer science, and informatics degrees. For students, it is challenging to work with programming languages that require compliance with complex syntactic and semantic rules. The results show and demonstrate a positive impact on the development of students' skills when compared to previous courses. Development of basic skills is observed on digital circuits and computational electronics. It is concluded that students are highly comfortable with Arduino and Tinkercard, even though, due to the pandemic, the experiments are not performed physically. © 2021,Formacion Universitaria.

ABSTRACT

Objective: To list studies that show the relationship of long-term damage to the sense of smell in adult patients with COVID-19 (coronovirus disease), in order to facilitate access to information on the management of this sequel and thus address the problem. COVID-19, caused by SARS-CoV-2, emerged in the East Asian region and became a pandemic causing the death of millions of individuals. Fever, dyspnea, cough, arthralgia, myalgia, headache, rhinorrhea and diarrhea are the most prevalent symptoms, in addition to olfactory and taste changes, which commonly cause anosmia and dysgeusia. This literature review aims to list the relationships between long-term damage to smell in patients with Covid-19 and its possible treatment. Thus, we carried out a narrative review of the literature in the PUBMED database with the following keywords: "smell of loss";"Covid-19";"Chronic damage". Thus, we found seven articles, and two articles were discarded, the first for relating olfaction loss by COVID-19 in children only, a rare fact in this age group. And the second, for escaping the topic.

ABSTRACT

Myopia is an ophthalmological abnormality prevalent among human beings, it is characterized by the formation of an image anteriorly to the retina, with the ciliary muscle at rest. We can list genetics and environment as conditioning factors of this pathology;in the meantime, this last factor has acquired great importance nowadays, in view of the growing exponential increase in the use of electronic screens. This literature review aims to list the relationships between myopia and the overuse of screens. In this context, it is necessary to review the main international publications on this health problem in children under 4 years of age. Thus, we carried out a literature review in the PUBMED database with the following keywords: "Myopia";"Use of Digital Devices";"children", "computer", "covid". Although the relationship between the pandemic and the repercussions for ophthalmic health proposed in this work is an extremely relevant topic, it is known that there is still a need for further studies.

ABSTRACT

Undergraduate computing programs usually have high failure and dropout rates in the CS1 courses due to the variety of concepts, models and strategies related to programming to be learned in a short time span. This paper presents an experience of a CS0 remote workshop, planned and led by peers, with the goal of teaching introductory programming in Python to first-year Computer Engineering undergraduates. The workshop happened during the Covid-19 pandemic and took advantage of calendar postponements to offer a 12-week remote experience. From the data collected, we perceived high student motivation, medium to high engagement and medium self-regulation both in general and in programming issues. Analysis of the experience suggests that, after the workshop, students have positive perceptions of their own non-cognitive issues, in addition to feeling prepared to learn programming in the CS1 course. Peer learning allowed novice students to reduce barriers to learning, and to feel closer to their field of knowledge. To the senior students who led the workshop, it allowed them to mediate the learning process, to collectively build knowledge, and to learn while teaching. © 2021 IEEE.
