O processo histórico de disciplinariza??o da Metodologia do Ensino de Matemática
Ferreira, Viviane Lovatti;Santos, Vinicio de Macedo;
Bolema: Boletim de Educa??o Matemática , 2012, DOI: 10.1590/S0103-636X2012000100009
Abstract: since the early decades of the 20th century, one can note the presence of a discipline whose constitution, operation and objectives are aimed at teaching how to teach mathematics. historically, the course methodology of mathematics teaching has appeared in university programs aimed at preparing mathematics teachers under various different names. throughout such changes, the backgrounds and features of that course have been changing. using a research methodology based on documental analyses and oral history, and as a theoretical reference the studies of andré chervel (1990), the goal of this study was to understand the historical process of disciplinarization of the methodology of mathematics teaching in undergraduate courses to prepare mathematics teachers in public universities in the state of s?o paulo (usp, unicamp and unesp-rio claro), seeking to understand the origin and the historical development of that course, identifying contents and methods proposed as well as the changes the course has undergone.
Paulo Freire e a Academia
Jason Ferreira Mafra,Viviane Rosa Querubim
Eccos Revista Científica , 2011,
Abstract: This study shows Paulo Freire as an object and theoretical research in increasingly diverse fields of knowledge. The presence of Freire in higher education occurs in an ambiguous relationship. Although growth is observed, relatively expressive of interest in the work of Paulo Freire, is a low willingness of teachers to work with the Freirian reference in its undergraduate and graduate, in the training. The survey data also point to the contradiction between the impact Freire's work in research in the strict sense and the small impact of such research in the process of dissemination and appropriation of reference Freirian among professionals in education, particularly in relation the practice of those inserted into the educational arrangements of Basic Education.
A importancia do gerenciamento de resíduos sólidos urbanos
Viviane Amaral Ferreira,Elias Basile Tambourgi
Exacta , 2009,
Abstract: The most part of Brazilian cities disposes its solid waste without any adequate procedure, a custom that can cause environmental damages such as air, soil, superficial and underground water contamination, developing focus of diseases with the spread of pathogenic vectors and its consequent impacts on public health. This work tries to investigate and evaluate the significant aspects of urban solid waste management, focused on sustainable development, in order to assure the continue development of welfare, promote recommended procedures on public health and protect the environment from pollution.

Abstract: genetic control of common bean (phaseolus vulgaris) resistance to powdery mildew (erysiphe polygoni) was studied using segregating populations from the bean variety crosses jalo x esal 686 and esal 550 x esal 686. f2 plants, together with the parents, were inoculated and evaluated using a scale of values from one (plant without symptoms) to nine (completely infected plant). f2 plants were harvested individually, and f2:3 families were obtained. these families were evaluated in an 11 x 11 and 12 x 12 simple lattice statistical design for the jalo x esal 686 and esal 550 x esal 686 crosses, respectively, using the same value scale as the f2 generation. the segregation observed in f2 plants and f2:3 families indicated that two genes are involved in genetic control, due to a double recessive epistasis. the high linear regression coefficient (b) between f2 plants and their f2:3 family, 0.66 for esal 550 x esal 686 cross, and 0.71 for jalo x esal 686 cross, showed that the trait is highly heritable.

Sousa, Viviane Maria Xavier Ferreira;Sousa, Gilberto da Silva;
Revista Brasileira de Oftalmologia , 2007, DOI: 10.1590/S0034-72802007000400011
Abstract: report of a case of posterior persistent hyperplastic primary vitreous (phpv) case on a nine years old patient with low visual acuity on the left eye, referred by the school for ophthalmic evaluation. the phpv can embrace a wide spectrum of ocular alterations involving retina, vitreous, optic nerve, macula, crystalline, iris and ciliary body besides anomalies like mycroftalmia and microcornea. we point out the importance of early ocular evaluation in children, late diagnosis and late treatment, in order to minimize the possibility of future damages to the health of these children.

Arquivos de Neuro-Psiquiatria , 1999,
Abstract: Epilepsia refratária ao tratamento medicamentoso é condi o que interfere direta e negativamente na qualidade de vida dos pacientes, dificultando-lhes principalmente a integra o social. O tratamento cirúrgico tem se mostrado eficaz no controle das crises em casos refratários, ocupando lugar importante no tratamento das epilepsias. Avaliamos a qualidade de vida de pacientes epilépticos, antes e após o tratamento cirúrgico, através de um questionário sobre qualidade de vida, adaptado do QOLIE-10 aplicado em 12 indivíduos epilépticos adultos, operados consecutivamente. O questionário, com 10 perguntas, envolvendo aspectos psicossociais e relacionados às drogas antiepilépticas, foi respondido no período pré-cirúrgico e repetido num intervalo médio de 8 meses após a cirurgia. Na compara o do questionário no período pré-operatório com o período pós-operatório, observamos diferen as estatisticamente significantes em 70% das perguntas, mostrando melhora da qualidade de vida após a cirurgia. Nestes casos, a terapêutica cirúrgica tem forte impacto na qualidade de vida.

Arquivos de Neuro-Psiquiatria , 1999,
Abstract: Frontal lobe epilepsies may present difficulties in focus localization in the pre-operative work-up for epilepsy surgery. This is specially true in patients with normal MRIs. We report on a 16 years-old girl that started with seizures by the age of 8 years. They were brief nocturnal episodes with automatisms such as bicycling and boxing. Seizure frequency ranged from 4-10 per night. Scalp EEG showed few right frontal convexity spiking and intense secondary bilateral syncrhony (SBS). High resolution MRI directed to the frontal lobes was normal. Ictal SPECT suggested a right fronto-lateral focus. Ictal video-EEG showed no focal onset. She was submitted to invasive recordings after subdural plates implantation. Electrodes covered all the frontal convexity and mesial surface bilaterally. Ictal recordings disclosed stereotyped seizures starting from the right mesial frontal. Using a high-resolution tool to measure intra and interhemispheric latencies, the timing and direction of seizure spread from the right fronto-mesial region were studied. Motor strip mapping was performed by means of electrical stimulation. She was submitted to a right frontal lobe resection, 1.5 cm ahead of the motor strip and has been seizure free since surgery (8 months). Pathological examination found a 4 mm area of cortical dysplasia. Invasive studies are needed to allow adequate localization in patients with non-localizatory non-invasive work-up and may lead to excellent results in relation to seizures after surgery.

Abstract: This research evaluated the physical and chemical quality of 72 samples of crude milk from 9 farms in the Gameleira region, municipality of Sacramento, MG, Brazil, and 12 milk samples from the same farms collected from a community milk tank. Values for titratable acidity, density, cryoscopy, fat, total dry extract, defatted dry extract were determined (BRASIL, 1981). Results showed that 10 (13.9%) samples did not comply with at least one physical and chemical item required by Norm 51. The 12 milk samples from the community tank analyzed during the assay complied with Norm 51 for physical and chemical requirements. The use of community tank actually provides satisfactory quality milk with regard to its physical and chemical characteristics.

Acta Ortopédica Brasileira , 2010, DOI: 10.1590/S1413-78522010000200002
Abstract: introduction: to determine and compare thresholds of cutaneous sensitivity of lower extremities in diabetic patients with an ulcer on only one lower extremity. methods and materials: the study group included 20 patients with mean age of 61.6 and average time with diabetes of 12.4 years. all patients were previously tested using semmes-weinstein monofilament 5.07. sensitivity was evaluated using the two point discrimination test and the pssd? (pressure-specified sensory device) in order to assess touch thresholds in a quantitative manner, in g/mm2. three skin areas were tested: hallux pulp, dorsum of foot and medial heel, including four tests: 1 point static, 1 point moving, 2 points static and 2 points moving. results: mean 2 point discrimination distance in mm was higher in feet with ulcers, but the difference between extremities was only statistically significant for the hallux. with the pssd?, all patients had higher pressure thresholds in feet with ulcers when compared with feet without ulcers, in all tests, with statistical significance. conclusion: the pssd? was able to differentiate levels of sensation between extremities with and without ulcers in diabetic patients, with statistical significance.
