Authors: Marchenko BI , Plugotarenko NK , Semina OA
Published: December 2021

Introduction: Ensuring a further improvement of efficiency of the public health monitoring system requires integration of the modern health risk analysis methodology with a complex of adapted unified traditional and innovative analytical methods and data exchange with the environmental monitoring system.
Objectives: The study aimed to test and assess the accuracy of predicting the incidence of malignant neoplasms using an artificial neural network.
Materials and methods: The analyzed time series are presented by information from statistical reporting forms on malignant neoplasms in the city of Taganrog, Rostov Region. We applied a regression model and a forecasting modeling technique based on a feedforward artificial neural network of a multilayer perceptron type. An artificial neural network with 117 neurons in a hidden layer was created in the environment of the Matlab R2021a application package with a set of tools for the synthesis and analysis of neural networks Neural Network Toolbox using the Levenberg-Marquardt algorithm for its learning.
Results: Approbation of two forecasting models was carried out on learning samples of different duration including 15 and 34 years. In a comparative assessment of the accuracy of forecasts for 2018 and 2019, absolute and relative errors were estimated. The accuracy of the neural network forecasting model was higher than that of the regression model both for the total of malignant neoplasms and for most cancer sites. The absolute errors of forecasts for 2018 when using regression and neural network models were 17.05 and 1.49 per 100,000 population, for 2019 – 39.07 and 4.42, respectively. The prediction accuracy dropped with a decrease in the time series duration and an increase in the distance from the boundaries of the learning sample.
Conclusions: The feedforward artificial neural network of the multilayer perceptron type provides more accurate predictions using minimal input information compared to the regression model, which is its undoubted advantage.
El trabajo de Ibn Firnás
Authors: Macho Reyes Rafael Diego
Published: December 2021

La figura de Ibn-Firnás (810-886) es una de las representativas del área de filosofía, ciencia e investigación del Emirato Independiente de Córdoba, que es la fase inicial de la administración musulmana del territorio de la península ibérica entre el 756 y el 929, dando paso al Califato Omeya de Córdoba, del 929 al 1031 y los Reinos de Taifas entre el 1031 y el 1492, etapas en las que se organizaría la dominación musulmana de la Península.
Ibn-Firnás era miembro de una familia de origen bereber que vino en la primera fase de intervención de conquista liderada por Tarik y su familia se asentó en la sierra de la actual provincia de Málaga, trasladándose a Córdoba en su juventud para su formación y desarrollo personal, siendo un intelectual protegido por tres emires. Tal y como se reflejaría en los arquetipos intelectuales del Renacimiento (siglo xv), unos siete siglos después, es por ello que conocer su figura puede suponer no solo una valorización del personaje en sí, si no también un argumento a favor de la diversidad y el desarrollo del conocimiento que al-Ándalus supuso en el marco de la Edad Media europea.
Por otra parte, el desarrollo de conocimiento en áreas tan diferenciadas como la óptica, la aeronáutica, la poesía o la música, hacen de su figura un referente cultural a valorizar, divulgar y comunicar que permita ofrecer nuevas perspectivas y contexto histórico.
Más allá del libro y el aula: el patrimonio filosófico
Authors: Arcos-Pumarola Jordi
Published: December 2021

El presente artículo tiene como objetivo explorar canales comunicativos sobre la filosofía en espacios de educación no formal e informal. Para ello, se toma como punto de partida la noción de patrimonio y, en especial, la de patrimonio literario, para bosquejar la aplicación de dicho concepto al ámbito filosófico. Así pues, se examinan las distintas acepciones del concepto de patrimonio filosófico y, a partir de esta definición, se realiza una distinción entre tradición filosófica y paisaje filosófico, profundizando en el significado y extensión de este último. De este modo, a partir de una comprensión de la influencia de la filosofía como expresión cultural en el territorio, se dibujan los recursos y estrategias para generar discursos sobre la filosofía y su historia a través de una base tangible como es el paisaje filosófico y sus lugares.
Forecasting the Transmission Trends of Respiratory Infectious Diseases with an Exposure-Risk-Based Model at the Microscopic Level
Authors: Cui Ziwei , Cai Ming , Xiao Yao , Zhu Zheng , Yang Mofeng
Published: December 2021

Respiratory
infectious diseases (e.g., COVID- 19) have brought huge damages to human
society, and the accurate prediction of their transmission trends is essential for
both the health system and policymakers. Most related studies concentrate on
epidemic trend forecasting at the macroscopic level, which ignores the
microscopic social interactions among individuals. Meanwhile, current microscopic
models are still not able to sufficiently decipher the individual-based
spreading process and lack valid quantitative tests. To tackle these problems,
we propose an exposure-risk-based model at the microscopic level, including 4
modules: individual movement, virion-laden droplet movement, individual
exposure risk estimation, and prediction of new cases. First, the front two
modules reproduce the movements of individuals and the droplets of infectors’ expiratory
activities. Then, the outputs are fed to the third module for estimating the
personal exposure risk. Accordingly, the number of new cases is predicted in
the final module. Our model outperforms 4 existing macroscopic or microscopic
models through the forecast of new cases of COVID-19 in the United States.
Specifically, mean absolute error, root mean square error and mean absolute
percentage error by our model are 2454.70, 3170.51, and 3.38% smaller than the
minimum results of comparison models, respectively. In sum, the proposed model
successfully describes the scenarios from a microscopic perspective and shows
great potential for predicting the transmission trends with different scenarios
and management policies.
Contextual Bandit Based Rate Adaptation Mechanism for IEEE 802.11 Mobile Wireless LANs
Authors: Sen Arkadeep , Sivalingam Krishna
Published: December 2021

Rate adaptation (RA) is used in IEEE 802.11 WLANs to determine the optimal datarate for a particular channel condition. It becomes especially difficult to determine the optimal datarate for the new High-Throughput WLANs (802.11ac/ax) since the number of available datarates in these standards are very high. Moreover, a mobile environment poses additional challenge in RA as the channel conditions will keep on changing from time to time. In this paper, we propose a Contextual Bandits based Rate Adaptation (ContRA) algorithm for mobile users in IEEE 802.11ac/ax standards. Based on the Received Signal Strength Indicator (RSSI) range that the receiver is currently in, the RA algorithm tries to determine the optimal rate from the rate set suitable for packet transmission in that RSSI range. Performance studies show that the proposed RA algorithm is able to adapt to changing channel conditions and quickly choose a suitable datarate for those channel conditions.

Published: December 2021

The review presents the main aspects of the work "Irmãos: Uma História do PCC", by Gabriel Feltran. The author presents an explanatory model about the nature of the PCC organization and outlines a historical overview of the faction. His observation from the outskirts of São Paulo allowed him to identify the form of organization of the PCC and its influence on the operating logic of the neighborhoods where it operates. According to the author, the PCC consists of a secret society whose purpose is to unify actors in the world of crime to strengthen them and achieve success in the fight against the “system”, understood as the whole of the State, the police and the system. prison, diverging from usual interpretations that classify it as a commercial or military entity.

Gestão do conhecimento em ferramentas de chat no contexto organizacional
Authors: Pereira Kássia Rayane , Tenório Junior Nelson Nunes , Menegassi Cláudia Herrero Martins
Published: December 2021

In a dynamic context, organizations are looking for ways to gain competitive advantages. In this sense, the wide use of technological tools, such as chat, to offer products and services, communication, knowledge sharing, among others, stands out. However, if there is no adequate storage of knowledge created in these tools, the loss of organizational knowledge may occur, making it impossible to recover and use knowledge, as well as the creation of Organizational Memory (OM). In this way, knowledge management (KM) becomes a fundamental discipline to treat knowledge and make it available in a useful way for the organization. Thus, the objective of this research is to systematize practices for the retrieval of knowledge in chat tools in the organizational context. To this end, exploratory research was carried out, with a quantitative-qualitative approach, with the technical procedures of text mining and ethnography in digital media. With the results, it was possible to present five KM practices for knowledge retrieval: Advanced Search Tool, Content Management, Skills Bank, Knowledge Bases, and Virtual Collaborative Environments. From such practices, it is concluded that it is possible to recover knowledge in chat tools, avoiding the loss of organizational knowledge and enabling the creation of the group's MO.

Published: December 2021

The Brazilian Intelligence Agency (ABIN) is responsible for preparing the Knowledge Protection Plan under the Brazilian Intelligence System (SISBIN). For this, it applies knowledge related to information and communication security for protecting the national critical infrastructure. In this context, ABIN produces strategic recommendations for the Federal Public Administration (APF), prospects its vulnerabilities and safeguards its critical IT infrastructure. However, knowledge about this protection is fragmented in the processes of risk analysis,  computational security and information security governance, represented by a set of ontologies. This article reports ABIN's experience in using Ontology Engineering techniques and tools for the combination of ontologies and knowledge extraction related to the protection of IT infrastructure of APF. This knowledge helps the collaborative work of the many actors involved in this process within SISBIN.
Um dos cativeiros da liberdade
Authors: Ferraz João Felipe de Almeida
Published: December 2021

The present work seeks to deal with the Brazilian land structure, ruled by the maxim of “captivity of the land”, as one of the founding elements of structural racism in Brazil. The distribution of land has as core the concentration, from the Portuguese colonization to the present day. From the exploitation of the work of the enslaved black population for more than three and a half centuries, a model of agricultural production through huge estates was founded, turned to the exportation. After slavery ended, black people, in addition to not being assisted or repaired by any of the material and moral damage caused by this phenomenon, had their lives depreciated in many ways, one of these was the deprivation of access to land. When considering the importance of territoriality for the reproduction of the lives of these populations, the study aims to point how racism and the historical evidence of land concentration, which remains until today, constitute the same social structure; counting on the direct interference of Brazilian political institutions. This discussion is important at a time when the agroindustry expands itself territorially at an increasing speed and the debates about structural racism gain popular and media attention - except, however, when it comes to the advance of expropriations (agricultural frontier) in the lands by quilombola and/or indigenous peoples, as these issues are not usually treated in a relational way.

A descoordenação intergovernamental durante a pandemia da covid-19 no Brasil
Authors: Pozzer Márcio Rogério Olivato , Neuhold Roberta dos Reis
Published: December 2021

This paper examines how intergovernmental incoordination during the Covid-19 pandemic in Brazil affected the debate about the educational inequalities, in the context of debates about the Exame Nacional do Ensino Médio (Enem) (National High School Exam). Based on an analysis of the political practices of President Jair Bolsonaro and the Minister of Education, it argues that the resumption of the pendulum movement between the dual and cooperative models of federalism has removed the federal government from the role of coordinator of public policy systems. In this context, discussions about the socio-economic inequalities were disqualified and federative units turned into political opponents. It is concluded that the brakes and counterweights played a decisive role in minimizing institutional damage. In isolation, the federal government failed to coordinate public policies that would mitigate the socio-economic problems aggravated by the pandemic.
ESTOICISMO DE EPICTETO E A FILOSOFIA ORIENTAL DO VEDANTA: SUAS DIFERENÇAS METAFÍSICAS
Authors: Fontoura Fernando
Published: December 2021

Na parte da ética e dos preceitos para um bom desenvolvimento ético a filosofia do estoico Epicteto tem muitas convergências com as práticas e os ensinamentos de filosofias orientais, a ponto de algumas pesquisas sobre essas concordâncias terem sido levadas a cabo em algumas escolas. No entanto, apesar dessas convergências, nosso estudo preliminar pretende mostrar que há diferenças substanciais e importantes entre as metafísicas de ambas as filosofias que apoiam essas práticas e princípios éticos. Além de algumas diferenças nos fundamentos metafísicos entre essas filosofias, a que nos chama atenção é sobre o fim último que ambas declaram e o qual dá sentido e significado tanto às práticas éticas quanto seus princípios. Aquele que pratica ou estuda esses princípios metafísicos de ambas as filosofias, embora tenham práticas convergentes, têm um direcionamento de fim último completamente diferenciados, o que influencia em suas justificativas morais e naquilo que chamamos hoje de sentido da vida. O objetivo desse artigo é mostrar essas diferenças para um melhor entendimento das idiossincrasias de cada filosofia e assim, para estudos posteriores de suas éticas, considerar essas diferenças como caraterísticas fundamentais e irrevogáveis de cada escola filosófica para evitar aproximações metafísicas em função das práticas éticas convergentes.

Este artigo trata de uma lógica de caráter intuicionista (construtivista) e do método dos tablôs, que tem maior interesse computacional por ser procedimento dedutivo, em geral, mais rápido e eficaz que o axiomático dedutivo. A meta é apresentar a lógica intuicionista I1, que foi originalmente apresentada em um sistema dedutivo axiomático, como em Sette e Carnielli (1995), através do método dos tablôs. Por ser considerada intuicionista, também deve ser considerado o aspecto construtivista da lógica I1.

Vygotsky e a defectologia
Authors: Ruppel Cristiane , Hansel Ana Flávia , Ribeiro Lucimare
Published: December 2021

Lev Vygotsky’s learning theory about Defectology is invaluable in the field of teaching students with disabilities. In the mid-twentieth century, the theorist promoted a revolution in the educational care of these students, as he criticized the negative concepts and coercive methods to which many of them were previously subjected, thus causing changes in the ways of thinking, treating and educating children with disabilities at school. From the study of this fact, the objectives of this theoretical essay were outlined, in an attempt to investigate Vygotsky’s contributions to the education of people with disabilities nowadays, to present the different historical contexts, in which we understand that the theoretical assumptions of the author still needs today to be recommended in the pedagogical practice of teachers working in this area, to describe the process of social compensation and to analyze the alternative and educational paths he points out to help overcome the child’s limitations. Thus, we conclude that Vygotsky’s perspective is empowering, as it places the teacher as a social mediator and the school as responsible for organizing the necessary adaptations to include the student. Furthermore, the author describes culture as fundamental for the creation of paths with alternation, and adequate teaching as a means of compensation that constantly  challenges these students. By basing their pedagogical practice on these principles, the teacher finds many subsidies to provide quality education to children with disabilities and allow their social inclusion.

The experience report presented here deals with the context of the special educator and the Núcleo de Apoio as Necessidades Educacionais Especificas (NAPNE) in a lightning bolt of the Federal Institute of São Paulo in the countryside. The objective of this article is to share positive experiences of an action with assumptions of coeducation or collaborative teaching and to point out challenges experienced in the institution regarding the schooling of the Public-Target Student of Special Education (PAEE) of the Technological Professional Network. The present text shares practices of curricular accessibility, brings for discussion the importance of the special educator in the context of the NAPNE and the forecast of the Specialized Educational Assistance. It was realized that the construction of accessibility for the student is based on a joint construction of different professionals and with the student himself, that the actions carried out by the special educator were focused on the work developed in the context of common room and not in the contract, with possibilities of work based on collaborative teaching. The report brings the beginning of this path, as Specialized Educational Care is a recent practice in this context, leaving as a suggestion the importance of studies on the performance of these professionals and greater socialization of the work performed.

Published: December 2021

Botany consists of studying plants, and sometimes are necessary equipment such as microscopes and stereo microscopes that are inaccessible for elementary school. The botany stigma is resultant of tradicional methodology and the scenario is even more adverse for students with Special Educational Needs (SEN), such as the visually impaired. To improve teaching in disciplines such as botany, that has content whit a complex approach, teachers and researchers have joined forces to develop alternative and inclusive methodologies. The present work aimed to evaluate the realization of practical activities such as the elaboration and use of tactile models in the teaching-learning process and as a form of Inclusive Education. The work was developed in a class from the 7th of elementary school in Paulista-PE, in which data collection was done through questionnaires applied before and after the practical activity in addition to sensitivity tests using tactile models. The results obtained revealed that the development and use of didactic models were positive for the teaching of botany and for the students, with or without vision, and expanded their views and concepts about plants and bryophytes. The method of making the models by the themselves allowed the students to develop other skills such as creativity and improve their ability to interact with colleagues and teachers, contributing to their training as educators and citizens.
Modelo de merenda escolar no ensino primário em Angola
Authors: Chiquemba Catarina Cuva de Fatima Vilar
Published: December 2021

O presente artigo tem como objetivo mostrar o sistema estrutural e funcional do programa de merenda escolar no ensino primário em Angola, regulado pelo Decreto Presidencial 138/13 de 24 de Setembro de 2013, bem como descrever a sua importância para as comunidades locais e para os alunos do Ensino Primário em Angola. Antes disso, entretanto, se faz necessária uma descrição sobre o sistema de educação e ensino de Angola no âmbito da Lei n.º 17/16 de 7 de Outubro de 2016. Considera-se importante fazer esta abordagem, visto que, deve-se reconhecer que as Políticas Educacionais no Ensino Primário, ligadas à Merenda Escolar, depositam capital importância principalmente nas zonas rurais e no seio das famílias mais desfavorecidas ou com renda econômica baixa. Por outro lado, nota-se que a merenda escolar tem sido alvo de uma política implementada pelo Governo Angolano no âmbito do Plano de Desenvolvimento Nacional, contendo vários eixos, dentre os quais: o Setor da Educação, que se liga ao Programa Municipal Integrado do Desenvolvimento e Combate à Pobreza, com a finalidade de contribuir para a manutenção das crianças na escola, contribuir na sua dieta alimentar para que tenham maior empenho nas atividades escolares por um lado e, por outro, valorizar a produção local para o consumo diário nos lanches da merenda escolar.

Published: December 2021

Introduction: the context of the Covid-19 pandemic in the Brazilian North region is worrying. There is a lack of resources for Public Health, a low human development index, and poverty indicators above the national average.
Objective: to analyze mortality and lethality from COVID-19 in the State of Roraima, Brazil.
Methods: this is an ecological time-series study of secondary data on COVID-19 in Roraima, Northern Brazil, from March 2020 to July 2021. The incidence, mortality, and lethality rates due to COVID-19 were calculated. The Prais-Winsten regression model was used to calculate the time series trends. Trends were classified as increasing, decreasing, or stationary. The trend was considered static when the p-value was not significant (p>0.05).
Results: in the state of Roraima, from March 2020 to July 2021, there were 123,125 cases and 1,903 accumulated deaths due to COVID-19. The first wave (March 2020 to October 2021) of COVID-19 recorded the incidence rate (2,995.30 new cases per 100,000 inhabitants - July 2020) and mortality (56.32 deaths per 100,000 inhabitants - June 2020) higher lethality. However, in the second wave (November 2020 to July 2021), the highest lethality rate was observed (3.47% - February 2021). It was observed that during the first wave, the incidence rate of COVID-19 showed increasing trends. During this period, the mortality rate had a stationary tendency (p>0.05) and the percentage lethality with a decreasing trend (p<0.05). During the second wave, there was a more aggravating scenario for lethality, which changed from a daily reduction rate of 0.90% to stationary trends.
Conclusion: the pandemic in the state of Roraima is not yet under control, so it is necessary to strengthen strategies to mitigate the spread of the pandemic in the region and prevent the formation of new waves.

Introduction: fear is one of the main factors associated with psychopathological disor-ders evidenced in the context of the COVID-19 pandemic.
Objective: translate and validate Fear of COVID–19 Scale (FCV-19S) into Portuguese Brazilian version, named Covid-19 Fear Scale (EMC-19).
Methods: cross-sectional study with 364 individuals recruited through social networks, considering as inclusion criteria: being over 18 years old and fluent in Portuguese. After participant consentment an electronic form was completed, which included the prelimi-nary Portuguese version and EMC-19, in addition to sociodemographic variables. Data processing was performed using the SPSS 26 version. For parametric measures, Pear-son’s coefficient and Student’s T were used, and for non-parametric measures the U of Mann Whitney. The magnitude of the correlation coefficients was classified according to Cohen’s criteria and the confirmatory factor analysis using AMOS 26.0. For internal con-sistency, Cronbach’s alpha.
Results: mean age of 33.11 years (±10,047), most of them female (n=332; 91,2%), with higher education (n=286; 78,6%), married (n=225, 61,8 %) and with children (n=300, 82,4%). Exploratory factorial analysis/EFA and confirmatory factor analysis/CFA made. Only one component emerged from the CFA, with an explained variance of 55,49%, re-sulting in a one-dimensional model with satisfactory adjustment indexes (X2/gl=2,135; RMSEA=0,061; CFI, TLI, GFI<0,095). Cronbach’s alpha coefficient is 876.
Conclusions: the construct validity of the one-dimensional structure of the EMC-19 was demonstrated, as well as its good internal consistency.

Published: December 2021

Introduction: the COVID-19 pandemic incited unprecedented global restrictions on society’s behavior. Home detachment and isolation measures applied during the COVID-19 pandemic can result in problems with sleep quality. It is an important measure to reduce the risk of infection from the COVID-19 outbreak.
Objective: to investigate the existence of a difference between the quality of sleep before and during the home distance imposed by the Covid-19 pandemic.
Methods: cross-sectional web-based survey was sent using different conventional social media to collect data from the study population. The evaluated group was composed of 124 subjects, 57 of whom were male and 67 were female from the city of Rio Branco / AC. For this study, the Pittsburgh Sleep Quality Index questionnaire (PSQI-BR) and a socio-demographic questionnaire were used. The volunteers received a link along with the description and purpose of the study. Finally, data analysis was performed using SPSS 22.0 software.
Results: sleep quality worsened significantly during home distance in four sleep components (subjective sleep quality, sleep latency, sleep drowsiness and overall PSQI score). During social distance, poor sleep was greater among respondents (OR = 5.68; 95% CI = 1.80–17.82; p = 0.70).
Conclusion: the results indicated that there was a significant difference between the quality of sleep before and during home detachment and sleep disturbance and the subjective quality of sleep before and during the period of the outbreak of COVID-19 were the components that most worsened in the state of sleep

Methods: cross-sectional study. The research was carried out in two different cities of the Brazilian confederation. One in Santo André, São Paulo and the other in Rio Branco, Acre, both in Brazil. This is a survey with an online platform, using the drive’s Google Forms tool to assess the population’s quality of life through the SF-36 protocol. The selection was carried out randomly in both groups (Acre and São Paulo), having respectively 109 and 62 participants in this first moment.
Results: regarding gender, women are in greater numbers participating in the city of Santo André, São Paulo than in Rio Branco, Acre, both in Brazil, with (80.6% and 48.6%), respectively. Likewise, in relation to the age group Santo André has an average age younger than in Rio Branco. When we compared the dimensions between the two states, performing a Mann-Whitney statistical analysis, statistical differences appeared in three dimensions, which were functional capacity, pain, and vitality, with better quality of life in these three domains for the city of Rio Branco.
Conclusion: the city of Rio Branco, Acre, Brazil, has a positive score when compared to the city of Santo André, São Paulo, Brazil, in most of the domains analyzed.

Introduction: COVID-19 impacted health systems worldwide; the virus quickly spread in Brazil, reaching the 27 Federative units in Brazil peculiarly. The northern region of Brazil recorded the lowest number of cases and accumulated deaths from the disease. However, it is a region of sizeable territorial extension and low demographic density, marked by socioeconomic inequalities and vulnerable groups, such as indigenous tribes, riverine peoples, and quilombolas. Sociodemographic factors may contribute to the dissemination of the coronavirus in the region; thus, studies are needed to analyze the epidemiological indicators related to the pandemic.
Objective: to evaluate incidence, mortality, and case fatality of COVID-19 trends in the state of Amapá, Brazil, from March 2020 to April 2021.
Methods: an ecological time-series study was conducted with publicly accessible data from the Health Department of the State of Amapá. Incidence and mortality rates per 100,000 inhabitants and percentage case fatality were calculated. Crude rates were calculated by municipalities, age, and sex, per month. The Prais-Winsten regression test was performed, and the trends of monthly rates were classified as increasing, decreasing, or flat.
Results: during the study period, there were 99.936 cases and 1,468 deaths accumulated by COVID-19 in the State of Amapá, Brazil. Macapá and Santana’s cities, which have the highest demographic density and Human Development Index (HDI), had the highest number of cases and deaths. The most vulnerable population was elderly males aged 70 years or over; these individuals had the highest cumulative incidence, case fatality, and mortality rates. The second wave of the disease (October 2020 to April 2021) illustrated a more aggravating scenario, with increasing incidence and mortality rates.
Conclusion: the COVID-19 pandemic in the state of Amapá, Brazil, is in increasing evolution, which illustrates that non-pharmacological prevention measures and acceleration of vaccination must be strengthened to avoid the development of future waves of the disease.

Introduction: coronavirus is part of a group of RNA viruses belonging to the Coronaviridae family, widely distributed in humans and other mammals. Currently, it has been seriously affecting the whole world, without a definitive cure yet.
Objective: to analyse the association between the HDI and confirmed cumulative cases of COVID-19 that occurred during epidemiological week 16 to 53 of 2020, in the State of Acre.
Methods: this is an ecological study of descriptive time series, evaluating the State of Acre and its 22 municipalities affected by COVID-19, in the period corresponding to the epidemiological weeks 16 to 53 of 2020. The State of Acre and its municipalities are aggregated by five regions with a total of approximately 881 thousand inhabitants, with an HDI of 0.663. Rio Branco is the state capital with 407,000 inhabitants. The 22 municipalities were analyzed, relating the HDI variables, confirmed cases per day and number of inhabitants to each other.
Results: it was observed that the population evaluated, affected by COVID-19 during SE 16 to 53 of 2020, in the State of Acre, had as predominant general characteristics brown skin color, male sex, and the evolution to death from the disease was related with older age and comorbidity. Acre had a mortality rate (deaths per 100,000 inhabitants) of 90.9 and a lethality rate of 1.9%, with the highest mortality rate observed in the municipality of Rio Branco (121.3/100,000 inhabitants) and lethality in Rodrigues Alves (2.9%). The incidence of COVID-19 in Acre was 4,759.9 cases per 100,000 inhabitants, the municipalities of Assis Brasil and Xapuri had the highest incidences in the state with 10273.7 and 9330.8 new cases per 100,000 inhabitants, respectively.
Conclusion: although the accumulated numbers of cases are different for the same day, the behavior is very similar, that is, the curves vary in the same way over time, regardless of the municipality observed.

Introduction: the new coronavirus (COVID-19) disease has been causing economic and health system impacts worldwide, triggering humanitarian crises in vulnerable regions, marked by high mortality rates of the disease. Brazil has been suffering an increase in the number of cases, characteristic of the formation of a second wave, with great epidemiological differences observed in the most diverse regions of the country. Many studies illustrate the behaviour of COVID-19 in the state of São Paulo, but there are gaps in the scientific literature on the epidemiology of COVID-19 in municipalities of the São Paulo metropolitan region that constitute an important industrial pole in Latin America, such as the region of Grande ABC.
Objective: to evaluate mortality and lethality trends of COVID-19 during the period March 2020 to July 2021, in municipalities on region of Grande ABC, metropolitan region of São Paulo, Brazil, divided into two periods (March to November 2020 and December to July 2021).
Methods: we conducted an ecological time series study with population data from the Brazilian Ministry of Health. We collected the number of cases and deaths confirmed for COVID-19 in the municipalities that make up the region of Grande ABC (Diadema, Mauá, Rio Grande da Serra, Ribeirão Pires, Santo André, São Bernardo do Campo, and São Caetano do Sul) from March 2020 to July 2021. Prais-Winsten linear regression was performed, and the percentage of daily change was calculated. Differences were considered significant when p<0.05.
Results: in region of Grande ABC, in the period analysed, 217,264 cases and 10,004 deaths of COVID-19 were recorded. Although the mortality rate remained stationary during the first wave (March to November 2020) and the second wave (December 2020 to July 2021); lethality transitioned from decreasing during the first wave to increasing during the second wave, with rates varying according to municipality.
Conclusion: trend analyses in incidence, mortality, and lethality rates assist in understanding the behaviour of the COVID-19 Pandemic in the region known as Grande ABC. Efforts must be maintained throughout the region to control the Pandemic.

Introduction: at this critical moment of the COVID -19 pandemic, we observe the social withdrawal and the break from the routine of individuals in society, for people with disabilities who need adequate support and a routine of more intense and effective activities may feel a greater need for care and attention of family support for solving everyday problems.
Objective: to identify factors associated with the impact of the pandemic on the quality of life of individuals with disabilities and their caregivers.
Methods: a virtual survey was carried out with parents and caregivers of people with disabilities to identify the main factors associated with the impact of the Pandemic on daily life and social relationships between family and community.
Results: of the parents and caregivers we had access to and answered the questionnaire, 90% are residents of the ABC region of São Paulo. Their children and adolescents with disabilities are between 4 and 18 years old. The main scores of caregivers on difficulties in care during the pandemic, 70% felt helpless at some point, 17% had difficulties in performing self-care activities, 42% had anguish and fear during the period, 83% have the greatest responsibility for household decisions, and about 50% can share those decisions.
Conclusion: the main complaints about the care of people with disabilities during the COVID-19 pandemic are related to the feeling of fear and anguish that affects decision-making and family relationships, which influences self-care activities and mental health of this population.
