Since the first detected cases of COVID-19 in Brazil, researchers have made a great effort to try to understand the disease. Understanding the impact of the disease on people can be instrumental in identifying which groups can be considered at risk. Therefore, this study researches a probabilistic model based on a statistical model of non-linear regression analyzing the following variables: age, if you are a health professional, if you are resident in the Metropolitan Region of Belém (RMB), State of Pará and gender with the objective of identifying those people who have a greater impact on the number of people infected and killed by COVID-19, that is, people who are more likely to die. To carry out the research, we used the data of all infected people by COVID-19 in the State of Pará until July 2020. It can be verified according to the proposal of the probabilistic model that elderly people, with a odds ratio of 1.69 (95% CI 1.52-1.88), residents of Metropolitan Region of Belém, with an odds ratio of 2.14 (95% CI 2.02 - 2.27) and men, with an odds ratio of 1.83 (95% CI 1.73 - 1.95) are groups of people with a higher risk of dying from diseases, while health professionals, with a 0.36 chance ratio (CI9 5% 0.29 - 0.45), are less likely to die.
The present work deals with the Index of Failures in calculus disciplines in Engineering courses, as they involve concepts that during high school, before entering higher education, are little spoken, becoming a discipline that scares students. The methodology was carried out through quantitative and qualitative analyzes in order to evaluate the failure rates in the calculus discipline offered at the Faculty of Engineering, Architecture, Urbanism and Geography at the Federal University of Mato Grosso do Sul. The objective was to understand the reasons that influenced the failure in this subject, including remote teaching during the COVID 19 pandemic. of students retained in this discipline, were some of the reasons raised by students as justification for failure.
A pós-graduação em educação em ciências e matemática no Brasil tem se consolidado como importante campo de pesquisa na área de ensino. Esse estudo buscou responder a seguinte questão: Em que aspectos as teses em Educação Matemática produzidas no Programa de Pós-Graduação em Educação em Ciências e Matemáticas – PPGECM reverberam nas práticas sociais dos professores pesquisadores egressos do programa, e suas possíveis repercussões e desdobramentos? Portanto o objetivo foi analisar as teses em Educação Matemática, produzidas no Programa de Pós-Graduação em Educação em Ciências e Matemática –'PPGECM do IEMCI/UFPA, identificando os discursos e suas interseções/consequências nas práticas sociais dos pesquisadores egressos do programa. Desse modo, defendemos a tese de que as pesquisas doutorais produzidas pelos egressos do PPGECM têm produzido impactos, consequências e desdobramentos relevantes que repercutem nas práticas sociais desses sujeitos autores, por meio da participação em grupos ou projetos de pesquisa acadêmica, reflexões críticas sobre suas próprias práticas, incremento na produção de artigos científicos e, sobretudo, inserção no processo de formação acadêmica e de novos pesquisadores para a região amazônica.
Este trabalho apresenta abordagens didáticas intermediadas por cenários urbanos do cotidiano de educandos que podem contribuir para aprendizagens mais eficazes da disciplina de Matemática nos anos finais do Ensino Fundamental. Esta pesquisa bibliográfica busca, na metodologia sociointeracionista, um vetor de ensino e baseia-se em trabalhos de historiadores, matemáticos, cartógrafos, jornalistas, dentre outros profissionais ligados a temática, além de investigação autoral realizada in loco, para exploração de imagens e coleta de informações com populares sobre os patrimônios histórico-arquitetônicos que são objetos de problematizações matemáticas nesta obra. Os resultados obtidos sinalizam possibilidades plausíveis de abordagens didáticas de ensino que, utilizando a arquitetura centenária da Praça da República em Belém do Pará, traduz-se em formas de aprendizado dinâmico e significativo aos alunos.
The work deals with the substitution of a transcendental function by a polynomial one, determined through Newton's Interpolator polynomial, in a certain interval, so that the characteristics in that space have a performance similar to that of the original function. Research enables numerous applications in the scientific field, as polynomial functions allow better predictability in the display of their graphics as well as in the entry of analytical points and results that are easy to manipulate and display. Some examples of application in the calculation of integrals were presented, presenting the calculations and obtaining the interpolating function. A comparative table was displayed with four transcendental functions, presenting equally acceptable results. The substitution of these functions in the integral calculation allows results with errors with a possibly acceptable margin in pre-established intervals.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
