Item Concepção e instalação de pré tratamento simplificado de esgoto doméstico no semiárido de Pernambuco(2018) Silva, Aureliana Greice Oliveira da; Montenegro, Abelardo Antônio de Assunção; http://lattes.cnpq.br/7947714302950574; http://lattes.cnpq.br/5247521278052200Item A dialogicidade como meio de enfrentamento à violência escolar e fortalecimento da autonomia infantil numa escola democrática(2019-11-21) Andrezzo, Clara; Ferreira, Hugo Monteiro; http://lattes.cnpq.br/9846855940173584; http://lattes.cnpq.br/9709122120661613O presente trabalho tem como objetivo compreender a contribuição da dialogicidade na escola como base para processos escolares democráticos, e como ferramenta para o enfrentamento e a prevenção à violência escolar. A escolha desse tema surgiu da vontade de compreender se efetivamente o fortalecimento das crianças, tendo o diálogo como princípio, pode auxiliar no enfrentamento à violência escolar? A pesquisa realizada é de natureza qualitativa, e utiliza a observação participante como método, entrevista semi-estruturada e questionário como técnicas de construção de dados. O lócus foi numa escola da Rede de Ensino Pública Municipal do Recife, localizada na Zona Norte da Cidade. Considerando que a escola pode ser um espaço e um tempo em que o diálogo seja fundamental para o fortalecimento da autonomia das crianças, nos dedicamos a observar os casos de violência, e identificar os dispositivos facilitadores de diálogo presentes na escola, além de analisar os princípios constitutivos de uma escola democrática, evidenciando a repercussão em processos dialógicos.Item A utilização da robótica como alternativa para o trabalho com comprimento da circunferência e ângulo(2019-07-24) Assis, Pablo Oliveira de; Costa, Wagner Rodrigues; http://lattes.cnpq.br/7087770599703498Math teachers often realize kids struggle about geometry and units of measurement. specifically, about angles and circumference applications. This article shows how these concepts can be explored using the educational robotic to reach an active learning over a teacher supervision. For this research we invited 6th grade students and the data showed that association with mathematics concepts and technology made it easier to think about math and use it to solve problems.Item A canção popular como recurso didático no ensino de História: um estudo sobre concepções e práticas docentes(2019-12-13) Andrade, Lukas Alisson Gouveia de; Silva, Lucas Victor; http://lattes.cnpq.br/0058476610695399; http://lattes.cnpq.br/4795559345410177This article aims to investigate teaching conceptions about the use of popular song in History Teaching. To this end, we conducted interviews with history teachers working in basic education. Our sample considered Master students and graduates of the Professional Master in History Teaching of the Federal University of Pernambuco. The results were analyzed using a qualitative and quantitative approach and content analysis from the categories: teaching conceptions, planning, classroom procedures and assessment.Item Aprendizagem de máquina para a identificação de clientes propensos à compra em Inbound marketing(2019-07-12) Silva, Bruno Roberto Florentino da; Monteiro, Cleviton Vinicius Fonsêca; Soares, Rodrigo Gabriel Ferreira; http://lattes.cnpq.br/2526739219416964; http://lattes.cnpq.br/9362573782715504The most important point for a company should always be the customer and getting new customers is not always an easy strategy. Digital marketing techniques study how to attract new customers to businesses using digital platforms. By virtue of the popularization of these means, the strategies had to be shaped to the new possibilities. With just one click you can reach thousands of individuals, which means many new leads for the company. However, filtering out which of these individuals are really interested in the product or service offered by the company demands a lot of effort from the sales team. This overhead is detrimental in the sense that the company can lose revenue by not targeting the real opportunities. With the aim to minimize this problem, the present work offers a proposal whose objective is the automatic identification of the client achieved through digital marketing strategies. It is proposed the usage of Machine Learning techniques, in particular supervised classification algorithms, namely Decision Tree and Naive Bayes. It was used the Scikit-learn library available for the Python programming language. In addition, it was necessary to apply the SMOTE oversampling algorithm, due to the unbalance of the dataset. In addition, in order to optimize the classification, we used the techniques of attribute selection and model selection with hyperparameters adjustment. Finally, to evaluate the results, we used the confusion matrix, the precision and coverage metrics, and the accuracy and coverage curve. Due to the imbalance of the data, the precision metric did not report good indexes results, with averages of 5.5% of correctness. In addition, the coverage was around 83%. Even with such divergent results among the applied metrics, the present work reached its goal, identifying most of the real opportunities and reporting that using this approach, it would be possible to obtain a reduction of up to 85% in the effort applied by the sales team if they had to call for all the leads. As a consequence, the company may have a cost reduction with the resources applied to obtain new customers, allowing the sales team to find new customers with greater efficiency.Item Os indígenas aldeados e a guerra na documentação administrativa da Companhia Holandesa das Índias Ocidentais no Brasil (1630-1647)(2019-07-20) Silva, Lucas de Lima; Miranda, Bruno Romero Ferreira; http://lattes.cnpq.br/8746246350935536; http://lattes.cnpq.br/1677345577430632In this article, we will discuss the role of the indigenous villagers as an auxiliary military force in the expansion and safeguarding of the territory conquered by the Dutch West India Company from Portuguese America in the 17th century. The underlying questions that led to this research are based on the concepts, theoretical discussions and methods characteristic of a Historical Domain that emerged in National Historiography in the last decades of the 20th century: the “New Indigenous History”. The work of this field has left an important reassessment of the impact of the actions of Amerindian individuals and groups on historical processes and events, in the light of reinterpretations of certain concepts, as well as from the criticism of previous historiographies. To carry out this proposal, we will essentially analyze Dutch administrative sources in order to identify the extent - quantitative and qualitative - of the military employment of indigenous villagers, their relationship with war activity during the period in question and the centrality of the colonial “aldeamento” system to the practices of Dutch and indigenous people in the face of war.Item Autonomia territorial para existir: resistências e resiliências indígenas no marco da decolonialidade(2018-12-17) Santos, Isis Caroline Santana dos; Benzaquen, Júlia Figueredo; http://lattes.cnpq.br/0325443406402140; http://lattes.cnpq.br/1735378695592473El presente trabajo tiene como proposito analizar como las diferentes formas de construcción de territorialidad para los pueblos indígenas Nasa en Colombia y Xukuru en Brasil representan alternativas otras ante una configuración moderno/colonial presente en estos países y en América Latina, donde la lógica político social sigue siendo la de explotación de los pueblos y de la naturaleza. Para aclarar estos procesos, presentase de qué manera las teorías de la colonialidad y de la modernidad instauran la concepción económico instrumental de pensar la naturaleza y así explotar el medio ambiente y el territorio. Frente a eso, el objetivo es analizar como las injusticias y conflictos socio ambientales están relacionados con la colonialidad/modernidad presentadas, y de qué modo las estrategias de lucha por la autonomía territorial y alimentaria de estas poblaciones representan, no solo un rescate de la tradición, pero también una alternativa social de protección y respecto a las minorías identitárias y a la naturaleza. La investigación se hizo por medio de un abordaje cualitativa decolonial de análisis, que se dio por observaciones y entrevistas que consideraban no apenas la visión científica de método. Ese abordaje se refiere a perspectiva de los agentes como edificadores de sus narrativas, especialmente cuando se trata de sus modos de vida, y vista como urgente ante una historia de invisibilización epistémica y aniquilamiento resultantes de la imposición colonizada de la idea del ser, del saber y de la naturaleza. Desde eso, asumimos como hipótesis que las estructuras coloniales toman el território como local a ser conquistado e dominado, lo que afecta negativamente la natureza y fomenta desigualdades socios ambientales históricas, pero especialmente retroalimentan las violencias contra poblaciones invisibilizadas y sus luchas en defesa del territorio y de la vida. Esa hipótesis fue confirmada por medio de las vivencias con los pueblos y la participación en los eventos de La Liberación de la Madre Tierra y Agricultura Xukuru: A Ciência dos Invisíveis, guardiã da Cultura do Encantamento, que ayudaron tanto en la realización de las entrevistas como en la percepción que los dos pueblos comprenden la relación con la Pachamamma ó Madre Naturaleza. Los resultados muestran que, en ambos casos, la lucha territorial busca el establecimiento de relaciones que se oponen al modelo colonialde la naturaleza, priorizando la autonomía y la vida, llendoen contramano de la dependencia y subalternización histórica que los afecta.Item A formação da sociedade do cansaço: uma reflexão sobre a educação a partir de uma escola pública de Recife(2019-12-16) Silva, Lucas de Lima Gonçalves da; Brito, Paulo Afonso Barbosa de; http://lattes.cnpq.br/0891943804378064; http://lattes.cnpq.br/3769075927101151Havin in sight the alarming number of young students from Recife nowadays with psychic problems, like depression, anxiety, Burnout syndrome etc. The present work aims to analyze if it’s possible to estabilish a direct relationship between the socialization made by the education with the increanse in the rate of psychic disorders of this population. Does the current educational model exert neuronal violence in young people? If so, in what ways this violence is exercised? And what are the consequences of this violence? To verify the truth of the thesis and answer these questions, a field research was made using questionnaires and interviews with students and former students with the purpose of collecting data to be analyzed and support a theoretical discussion capable of verifying this thesis. It is concluded that it’s possible to estabilish a relationship between education and the population’s psychic illness insofar as it internalizes values and routines that throws the individual in a life full of neuronal violences that contribute to the formation of psychic problems.Item Implantação de quintais produtivos em busca da valorização e soberania alimentar da comunidade da Nova Tatuoca(2017) Ferreira, Joanne Kaline de Oliveira; Silva, Lourinalda Luiza Dantas da; http://lattes.cnpq.br/7013867423178814; http://lattes.cnpq.br/8545969062098278Item Atividade antimicrobiana de análogos da piperina(2018-08-02) Bezerra, Leonardo Alexandre Barros; Ramos, Clécio Souza; http://lattes.cnpq.br/3782004073843685; http://lattes.cnpq.br/3961756201958567The structural modification of natural compounds is of significant importance for medicinal chemistry, from 1981 to 2014 1328 medicines were approved for commercialization, of which 51.5% are of natural origin and 26.8% are derived from phytochemicals. An example is the natural amide piperine, which is the target of several biological investigations, and which has demonstrated the potential to act as a precursor to new compounds with application in the modulation of biological phenomena with the 1,2,4 oxadiazole nucleus, which are a class of heterocyclic that exhibit a range of biological activities and that can be used for the synthesis of potential microbial agents. This work aims to report the extraction of piperine by microwave. Reflux hydrolysis of piperine to obtain piperinic acid in moderate yields. Obtaining the ethyl piperininate esters and 3,4 methylenedioxy ethyl cinnamate with excellent yields. The synthesis of amidoximes using the conventional methodology of stirring with hydroxylamine hydrochloride, sodium carbonate and the corresponding nitriles with the substituents (p-nitro, p-toluyl, m-toluyl, benzo, piperonyl, 4-pyridine) in yields of 37% -98%. Using the methodology of synthesis of oxadiazole by microwave using ethyl cyano acetate esters with piperonylamidoxime, ethyl ester 3,4-methylenedioxy cinnamate with 4-pyridine and p-toluyl amidoxime in the presence of K2CO3 and DMF. All oxadiazol precursors were elucidated by IV and the 1,2,4-oxadiazoles synthesized characterized by 1H and 13C NMR. Some compounds were tested bactericidal activities, where the 1,2,4-oxadiazoles presented excellent results against Staphylococcus aureus and Klebsiella pneumoniae and one of the compounds presented luminescent activity a little reported in the 1,2,4 oxadiazoles.
