Redes neurais mlp aplicadas na previsão de casos confirmados de Covid-19 no Brasil

COVID-19 é a doença causada pelo vírus SARS-CoV-2, descoberto em 2019, e que se espalhou pelo mundo gerando uma pandemia com graves consequências sanitárias. Países lidam de diferentes formas para resguardar a saúde de sua população diante de um patógeno recém descoberto e com peculiaridades próprias. Muitos estudos estão sendo realizados sobre a COVID-19. No presente estudo, foi proposto um modelo de previsão de curto prazo baseado em redes neurais Multilayer Perceptron capaz de estimar o número de casos confirmados de COVID-19 no Brasil.

Perfil Epidemiológico dos casos de Covid –19 nos primeiros 100 dias de pandemia na 1ª região de saúde de pernambuco – Brasil

Objetivou-se caracterizar o perfil epidemiológico dos casos confirmados de COVID-19 ocorridos na 1ª Regional de Saúde do Estado de Pernambuco durante os primeiros 100 dias da pandemia em 2020. Realizou-se avaliação epidemiológica de abordagem descritiva com objeto de estudo as variáveis epidemiológicas dos casos confirmados de COVID-19 nos 20 municípios da 1ª Regional de Saúde, notificados por plataforma online. Verificou-se notificação de 25.506 casos suspeitos da Síndrome Respiratória Aguda Grave causada por SARS-CoV-2 e 51.740 casos suspeitos leves de COVID-19.

Combination of social machines and service-oriented relationships

The dissemination of the Web as a software development platform has led to a combination of computational and social elements to deal with the complexity of existing services and operations on the network, known as Social Machines. Social Machines establish relationships between people and machines through different views of relationships and their constraints. The role of Social Machines has changed the understanding of the nature of computing in complex operations and services, increasing the interactivity and connectivity of applications, collaborative platforms, and social networks.

Social reinsertion and the perception of positive impacts: a case study in the arcoverde forum, Pernambuco, Brazil

Sustainability must not be understood only as an issue of environmental preservation, but must encompass other aspects, consolidating a holistic view. Thus, it is understood that the concepts of social reintegration must be broad enough to encompass the various dimensions of sustainability. On the other hand, it is notable that awareness and sensitization is the best way for society to engage in the search for sustainable development, which is the way out to preserve current natural resources for the preservation of the lives of current and future generations.

Gestão de risco e exposição ocupacional de profissionais de saúde em meio a pandemia de Covid-19: revisão de literatura

A presente pesquisa tem como objetivo realizar uma revisão bibliográfica acerca da exposição ocupacional dos profissionais de saúde em meio à pandemia de COVID-19, e ressaltar a importância da segurança no trabalho para a equipe e para os pacientes. Trata-se de uma revisão integrativa da literatura realizada por meio de pesquisa nas bases de dados eletrônicos PUBMED, Scientific Electronic Library Online (Scielo) e Lilacs, desenvolvida a partir de artigos científicos, utilizando os seguintes descritores: gestão de risco, profissionais de saúde e COVID-19.

Dedifferentiation of leaf cells and growth pattern of calluses of capsicum frutescens cv. stromboli

In vitro cell suspension cultivation systems have been largely reported as safe and standardized methods of production of secondary metabolites with medicinal and agricultural interest. Capsicum frutescensis one of the most widely grown vegetable in the world and its biological activities have been demonstrated against insects, fungi, bacteria and other groups of organisms. The objective of this study was to establish a protocol for dedifferentiation of leaf cells of the cultivar C.frutescens cv.

Approaches to learning in the non-academic context: construct validity of learning approaches test in video game (lat-video game)

The subject-object interaction of knowledge studied by the field of learning approaches has been evaluated exclusively in the school/academic context. However, the field does not assume that these interactions are manifested only in this context. This article studies the validity of the Video Game Approach Test (LAT-Video Game), with the novel proposal to evaluate approaches in a non-academic context. The structural validity and its generality were investigated, as well as the predictive and divergent validity of the LAT-Video Game in two independent samples.

Experimental analysis of the reuse of waste from prefabricated concrete piles: case of a port work

Construction waste in large works is poorly studied. Port works have peculiar characteristics and it is interesting that designers have indicators of waste generation. In this work, the generation of waste from the activity of logging concrete piles and their reuse process was analyzed, generating indicators for the project. The research methods covered the quantification of the reuse of piles in the activity itself and the quantification of waste intended for disposal. Results showed that 49.2% of piles used leftovers, which represented 12.98% of the total length driven (242210 m).
