O IMPACTO DA INTERFACE ENTRE A APRENDIZAGEM BASEADA EM PROBLEMAS E A ARGUMENTAÇÃO NA CONSTRUÇÃO DO CONHECIMENTO CIENTÍFICO
Authors: Da Silva Ana Carla , De Chiaro Sylvia
Published: December 2018

O objetivo do presente trabalho é compreender o impacto que a interface entre a Aprendizagem Baseada em Problemas (ABP) e a argumentação desempenha para a promoção da construção do conhecimento científico. Tomamos como foco de análise, as interações dialógicas entre aluno-aluno e aluno-professor ao longo da resolução de um problema na metodologia ativa ABP, por entendermos que a configuração deste tipo de metodologia favorece o debate crítico e reflexivo de ideias. As análises foram feitas com base na perspectiva da argumentação enquanto mecanismo epistêmico e promotor do pensamento crítico e reflexivo, bem como dos pressupostos sobre os indicadores de alfabetização científica para a promoção da aprendizagem. Nossos resultados apontaram que, embora a metodologia ABP seja propícia ao desenvolvimento de interações dialógicas, por si só, não garante que a argumentação ocorra nem tampouco que os alunos expressem indicadores de alfabetização científica. Concluímos que o desenvolvimento de interações dialógicas depende muito mais do manejo do tutor através de determinadas ações discursivas, as quais fazem toda a diferença quando se pretende utilizar a argumentação para o processo de ensino e de aprendizagem.
High Efficiency with Small Coils Area Ratio of Magnetic Resonant Wireless Power Transfer System
Authors: Thabet Thabat , Woods John
Published: December 2018

Wireless power transfer using magnetic resonance requires cutting flux lines generated from the transmitter coil by the receiver coil. This letter shows that an exact one to one coil area ratio or CAR (i.e. primary relative to secondary) is not a pre-condition to obtain high efficiency. It is also shown that high efficiency can be achieved for relatively small CARs by adjustment of the turns ratio. We go on to show that it is possible to achieve a higher energy efficiency than the coil area ratio and the associated flux cut would dictate.
Analysis of Lossy Transmission Lines Terminated by Schottky Diode Circuit
Authors: Angelov Vasil G.
Published: December 2018

In the present paper we consider a lossy transmission line terminated by a circuit corresponding to a Schottky diode. On the base of Kirchhoff's law boundary conditions are derived. Then a mixed problem for the lossy transmission line system is formulated. We reduce the mixed problem for the hyperbolic transmission line system to an initial value problem for a system of differential equations with delays on the boundary. We prove existence-uniqueness theorem for oscillatory solution. The paper ends with numerical example with real values of the Schottky diode parameters.

Authors: Nwanya Anthony C. , Okeke O. C.
Published: December 2018

Using dynamic cone penetrometer tester (DCPT) to determine the CBR and bearing pressure of subsurface soils in parts of Owerri, southeastern Nigeria were investigated in this study. Six (6) DCPT were measured to the depth of 6 m. The data obtained from field DCP test was plotted on the graph of penetration resistance (mm/blow) versus penetration depth (m); which revealed the soil profile of three layers with different penetration consistencies and resistances. The highest PR (mm/blow) recorded was 11.4 mm/blow and the lowest is 55.5 mm/blow.  The layers encountered during the measurement ranges from loose, medium and dense soils, where the average thicknesses of loose layers ranges from 0.1 to 0.5 m, medium layers 0.5 to 3.0 m and dense layers 3.0 to 6 m. The average CBR values recorded at interval of 1m to 6 m depths are as follows: 5%, 8%, 12%, 15%, 16% and 16%. Accordingly, the averages bearing pressures calculated were 104.8 KN/m2, 165.5 KN/m2, 231.9 KN/m2, 283.3 KN/m2, 291.5 KN/m2 and 301.1 KN/m2. It shows significant increase in strength with depths.
Significance of biological membranes for accurate computational dosimetry of low frequency electric fields
Authors: Marzban S. , Saviz M. , Towhidkhah F.
Published: December 2018

Computational dosimetry has become the main tool for estimating induced electric fields within brain tissues in transcranial direct current stimulation (tDCS) which is recently attracting the attention of researches for motor function disturbances such as Parkinson’s disease. This paper investigates the effect of including or excluding the very thin meninges in computing tDCS electric fields using CST software. For this purpose, two models of the brain with and without meninges were used to induce electric field with two DC current electrodes (2 mA) in regions of the model referring to M1 and Prefrontal Cortex (FP2) similar to tDCS. Considering meninges, the results have shown differences in the induced field showing that there might be problems with conventional models in which meninges are not taken into account.
Infarct-core CT perfusion parameters in predicting post-thrombolysis hemorrhagic transformation of acute ischemic stroke
Authors: Langel Crt , Popovic Katarina Surlan
Published: December 2018

Background

Intravenous thrombolysis (IVT) is the method of choice in reperfusion treatment of patients with signs and symptoms of acute ischemic stroke (AIS) lasting less than 4.5 hours. Hemorrhagic transformation (HT) of acute ischemic stroke is a serious complication of IVT and occurs in 4.5–68.0% of clinical cases. The aim of our study was to determine the infarct core CT perfusion parameter (CTPP) most predictive of HT.

Patients and methods

Seventy-five patients with AIS who had undergone CT perfusion (CTP) imaging and were treated with IVT were enrolled in this retrospective study. Patients with and without HT after IVT were defined as cases and controls, respectively. Controls were found by matching for time from AIS symptom onset to IVT ± 0.5 h. The following CTPPs were measured: cerebral blood flow (CBF), cerebral blood volume (CBV), mean transit time (MTT), relative CBF (rCBF) and relative CBV (rCBV). Receiver operating characteristic analysis curves of significant CTPPs determined cut-off values that best predict HT.

Results

There was a significant difference between cases and controls for CBF (p = 0.004), CBV (p = 0.009), rCBF (p < 0.001) and rCBV (p = 0.001). Receiver operating characteristic analysis revealed that rCBF < 4.5% of the contralateral mean (area under the curve = 0.736) allowed prediction of HT with a sensitivity of 71.0% and specificity of 52.5%.

Conclusions

CTP imaging has a considerable role in HT prediction, assisting in selection of patients that are likely to benefit from IVT. rCBF proved to have the highest HT predictive value.

Authors: Duong Nguyen
Published: December 2018

NiFe2O4/ZnO core-shell nanocomposites were prepared by two-step methodology. First, NiFe2O4 nanoparticles as the cores were synthesized by using hydrothermal method, and then modified by sodium citrate. After that ZnO as the shell was coated on modified NiFe2O4 nanoparticles by two different chemical methods including hydrothermal and co-precipitation. The formation, crystal structure, morphology and magnetic properties of the uncoated and coated samples were investigated by using X-ray diffraction, Fourier transform infrared spectroscopy, scanning electron microscopy and vibrating sample magnetometer. It was shown that the core nanoparticles are single phase of NiFe2O4 with cubic spinel structure. Sodium citrate was well bonded on the surface of the modified nanoparticles. Contributions of the phases in the coated samples as well as structural parameters were determined from XRD data on applying of Rietveld refinement analysis. Magnetization of the core can be improved by adjusting the modification steps. XRD analysis result and SEM images revealed the formation of core/shell structure in the sample coated by using co-precipitation method.

Observa-se atualmente a crescente aplicabilidade do Dry Needling e Microgalvanopuntura sobre a dor musculoesquelética no pós treinamento de força muscular, porém não se encontram estudos que comprovem a eficácia das técnicas em lesões musculares. O presente estudo teve como objetivo avaliar os efeitos do Dry Needling e microgalvanopuntura sobre a dor muscular no pós-treinamento de força do músculo bíceps braquial, através de análise laboratorial de CK e Limiar de pressão a dor (PPT). A amostra foi caracterizada por 6 indivíduos do sexo masculino com média de idade de 23 (±3,9) anos, não praticantes regulares de atividade física em membro superior. Foi realizado ensaio clínico cruzado randomizado cego, no qual os indivíduos foram divididos em três grupos: Dry needling profundo com corrente microgalvânica (microgalvanopuntura), Dry needling profundo e controle, sendo realizada análise de CK e PPT. Foram utilizados banco scoot, barra com anilhas de pesos variados, medidor de pressão, striat IBRAMED® (aparelho de microgalvânica), agulha de acupuntura 0,40x0,25mm DONGBANG®. Foi realizado teste de normalidade de shapirowilk com p<0,05 e ANOVA TWO WAY – post hoc de Tukey α= 5%..Observou-se que o protocolo de treinamento foi eficaz, CK mostra aumento 24 à 48h e decréscimo 72h , não havendo diferença entre os grupos, sendo as técnicas de tratamento seguras, pois não variaram a expressão de CK em nenhum grupo de intervenção, tendo o controle o mesmo comportamento. No pós-tratamento do grupo de microgalvanopuntura, o PPT diminui, logo o indivíduo fica mais sensível ao toque na junção miotendinosa. Porém o grupo controle mostra que 24h – 48h existiu diminuição do PPT, devido ao treinamento de força e não pela intervenção. Conclui-se que o método de treinamento com 80% da carga de 10 RMs é suficiente para gerar lesão em bíceps braquial, sendo as técnicas de dry needling e microgalvanopuntura seguras em lesões musculares agudas.

Este trabalho teve como objetivo avaliar a influência do tratamento térmico nas propriedades físico-químicas, sensoriais e no teor de antocianinas em uma bebida não-alcoólica elaborada com cálices de vinagreira (Hibiscus sabdariffa L.). Preparou-se uma formulação contendo 20% de cálices de vinagreira in natura, 15% de açúcar de cana (sacarose) e 65% de água mineral. As bebidas in natura e as provenientes dos tratamentos térmicos, pasteurização e esterilização foram avaliadas quanto as características físico-químicas (acidez total titulável, sólidos solúveis totais, pH, sólidos totais), colorimétricas (L* e a*), sensoriais e quanto ao teor antocianinas totais. Não houve diferença significativa entre as bebidas termicamente processadas e a bebida in natura, em relação às características físico-químicas, exceto o pH, que foi inferior para o produto esterilizado. A bebida esterilizada obteve as menores médias de aceitação em relação aos atributos cor, sabor, impressão global e também intenção de compra, configurando rejeição dos avaliadores. As antocianinas presentes na bebida pasteurizada foram significativamente preservadas e as da bebida esterilizada atingiram o nível de 89,81% de degradação. Conclui-se que a pasteurização é o tratamento térmico mais indicado para a bebida não-alcoólica de cálices de vinagreira, já que esta não diferiu da bebida in natura, em relação ao conteúdo de antocianinas e às características físico-químicas e sensoriais.

Considerando que o ferro é um micronutriente essencial na fisiologia do organismo, o objetivo deste estudo foi avaliar os níveis de ferro sérico em assentados de Ituiutaba-MG, associado com Doenças Crônicas Não Transmissíveis (DCNT). O perfil socioeconômico, demográfico e epidemiológico foi avaliado em 143 assentados, sendo que destes somente 15 (10,5%) participaram da coleta de sangue. As amostras foram analisadas a partir de kit de diagnóstico, as medidas antropométricas foram aferidas e questionário semiestruturado aplicado. Os resultados revelaram maioria masculina (73,3%) e que declarou ter idade abaixo de 60 anos (80%), com baixa renda (66,7%) e baixa escolaridade (60%), não fumante (73,3%), não etilista (66,7%), sedentária (80%) e que tem alimentação saudável (86,7%). Além disso, apresentou majoritariamente IMC eutrófico (78,6%), circunferência da cintura ideal (60%), mas a relação cintura/quadril (RCQ) alterada (60%). Quanto às DCNT, 6,7% dos assentados declararam ter diabetes mellitus, 20% hipertensão arterial e 66,7% distúrbio neurológico, dos quais 33,3% deles apresentaram nível de ferro sérico acima do ideal. Apesar da minoria apresentar baixos níveis de ferro (6,7%), este parâmetro não foi correlacionado com os fatores de risco para DCNT. Os dados obtidos reforçam a efetividade de políticas públicas no meio rural que priorizem a educação preventiva em saúde.

Introdução: O tratamento padrão para o câncer de mama em estágios iniciais é a cirurgia conservadora e abordagem axilar, que podem produzir complicações, resultando em prejuízo funcional. A prática do método Pilates pode auxiliar no controle dessas complicações, melhorando a funcionalidade do ombro homolateral a cirurgia. Objetivo: Verificar o efeito do Método Pilates sobre o recrutamento de unidades motoras, flexibilidade e perimetria do braço de pacientes mastectomizadas. Metodologia: Estudo série de casos que acompanhou 5 pacientes pós mastectomia que foram submetidas a um programa de tratamento totalizando dezesseis sessões de Pilates. As avaliações foram realizadas antes e após o tratamento fisioterapêutico através das seguintes variáveis: recrutamento de unidades motoras dos músculos peitoral maior e deltóide; flexibilidade; presença de linfedema e dor. Para análise estatística foi utilizado o teste ANOVA TWO-WAY – post hoc de tukey com significância de 5%. Resultados: Foi possível observar melhora significativa (p<0,05) da flexibilidade da cadeia posterior, da perimetria de braço e recrutamento de unidades motoras do músculo deltoide médio. Conclusão: Conclui-se que o método Pilates teve efeito sobre flexibilidade, redução da perimetria do braço e sobre o recrutamento de unidades motoras do musculo deltoide médio e pode ser tratamento seguro e indicado para a reabilitação funcional dessas pacientes. Estudos com maior número de participantes e maiores períodos de tratamento são de extrema importância para a elaboração de conclusões mais sólidas.

O objetivo deste estudo foi analisar a associação entre a imagem corporal e a autoestima de pacientes com ostomias intestinais. Trata-se de uma pesquisa quantitativa, descritiva e de corte transversal, realizada no hospital Oncobeda, no Município de Campos dos Goytacazes/RJ. A amostra foi composta por 30 indivíduos em tratamento ambulatorial. Para coleta de dados foram usados três instrumentos: um questionário geral estruturado, a escala de satisfação com a aparência e a escala de autoestima de Rosenberg que foram aplicados na modalidade entrevista. Os dados foram analisados no software SPSS, versão 24.0. Observou-se um predomínio de mulheres, idosas, casadas, com baixa eescolaridade, em algum emprego, com uma renda familiar per capita de 2 a 3 salários mínimos e residentes no município onde este estudo foi realizado. A maioria possuía alguma crença e destes, a maioria se denominava católico.            Houve um predomínio de indivíduos com colostomia, de caráter definitivo e recentemente instalada. A principal causa para a instalação de um dispositivo coletor para a eliminação das fezes desses pacientes foi o Câncer. Evidenciou-se que a maioria dos participantes apresentou baixa satisfação com a imagem corporal (53,3%) e alta autoestima (83,3%). Essas variáveis apresentaram uma correlação forte (p=0,754) e significativa (P=0,06).
