Os Erros no Processo Ensino/Aprendizagem em Matemática

O objetivo deste artigo é contribuir com os questionamentos acerca do ensino da Matemática nas séries iniciais do ensino fundamental apresentando um “olhar” diferente e positivo aos erros em Matemática dos alunos no sentido em que os mesmos possam ser tomados como recurso metodológico e re-orientador da prática pedagógica por parte dos professores. Para tanto, este artigo apresenta uma fundamentação teórica sobre o erro, perpassando por uma breve incursão histórica acerca das pesquisas envolvendo essa temática no mundo e aponta quando esse tema começou a ser tratado no Brasil. Aborda também a questão da cultura avaliativa que acomete os professores e os agentes escolares. Palavras-chave: Erros em Matemática; Avaliação em Matemática; Prática Pedagógica.

Distúrbios funcionais da oclusão e sua correlação com radiografias transcranianas da articulação temporomandibular, em pacientes portadores de fissuras labiopalatais

Anamnesis, clinical examinations and temporomandibular joint transcraneal radiographs for 22 adults with cleft lip and palate were carried out in order to evaluate the occlusion and correlate it with radographic findings. The conclusions were: 72.8% of the patients have at least one sign or symptom of craniomandibular disorders (CMD); although the occlusal conditions were severely altered, most of the signs and symptoms were classified as mild; the greater frequency of the signs and symptoms occurred among women; in the radiographic evaluation, all of the assymptomatic patients had both condyles with normal contour and all of the patients with altered contour had at least one sign or symptom; the bilateral centered position of the condyles in the fossa e did not warrant the absence of signs and symptoms; some patients with bilateral condyles positioned posteriorly or caudally or even assimetrically, did not present signs and symptoms of dysfunction; the radiographic findings should be correlated with clinical findings; and a great number of patients were not observed with clinical board of C:MD caused by the occlusion. Key words: Radiography; temporomandibular joint; temporomandibular joint syndrome; cleft palate; dental occlusion

Produção e comunicação da informação em ct&i gt7 da ancib: análise bibliométrica no período 2003/2009

The aim of the present research is to analyse Ancib’s scientific production in the workgroup GT7 named Production and Communication of Information in ST&I, between the years of 2003 and 2009, through bibliometric indicators, from which it is possible to indicate what is more important or significant within a scientific field or context, so as to therefore analyse trends, existing relations or processes. The bibliometric studies are an approach method for the analysis of science behaviour in a given field. More specifically, by means of production and connection indicators, it aims at revealing and portraying the most productive authors, the kind of authorship present in this group, the most recurrent themes, most productive institutions, and the collaborative network determined by the institutional coauthorships and their indicators, so as to map and visualize the main researchers and institutions of the present GT, within the period of time in question. The research procedure derived from studying the 94 research project results presented in the period, where the paper reference, summary and corresponding key words can be found. Analysis concerning the most productive authors, most recurrent themes, kinds of authorship and most productive institutions have been carried out from the variables under review. The collaborative network between the institutions was built using the Pajek software, and, with the help of the Ucinet software, indicators of degree centrality, betweeness centrality, and closeness centrality have been reached, besides the calculation of density. The results point to 11 researchers and 9 institutions as the most productive ones. The collaborative institutional network was shown to be fragile, presenting low density, and in general the participating institutions have presented low centrality indexes. As a conclusion, it has been observed that the themes focus, in general, on bibliometric analysis and their indicators, using regional and national data as their universe.

The genetic polymorphism of diabetic nephropathy

Introduction: The Diabetic Nephropathy (DN) affects approximately 40% of patients diagnosed with DM is associated with increased mortality from cardiovascular phenomena and is considered the main cause of Chronic Renal Failure (CRF) in patients dialectics. Methods: Searches were performed on Medline, SciELO, Lilacs and Cochrane databases using the crossing between the key-words: “genetic polymorphism” and “diabetic nephropathy”. Results: The selected studies indicated that diabetic nephropathy is the leading cause of chronic renal failure, which significantly reduces the life expectancy of diabetics. Currently, some factors may have connection with DN. They are: genetic predisposition based on family history, hypertension, and cardiovascular events, quality of glycemic control and lipid levels and blood pressure and smoking. Conclusion: Studies constants are essential to add new elements in the literature for the definition (s) of factor (s) gene (s) specific (s) of diabetic nephropathy.

Dinâmica da produção de serapilheira em diferentes sistemas de restauração florestal

The ecological restoration is an alternative to increasingly important for biodiversity conservation. However, actions need indicators to evaluate its effectiveness in restablishment ecological processes, including nutrient cycling. The objective of this study was to compare the annual litterfall from five different treatments for forest restoration, compared with a neighboring fragment of Seasonal Semideciduous Forest, in order to subsidize their management plans for ecological restoration. Litter traps of 0.25m² were used, and a total production was: 1700.6 Kg. ha-1.year-1(treatment 1), 7748.1 Kg. ha-1.year-1(treatment 2), 7120.8 Kg. ha-1.year-1 (treatment 3), 9254.5 Kg. ha- 1.year-1 (treatment 4), 7130.2 Kg. ha-1.year-1 (treatment 5) and 8876 Kg. ha-1.year-1 (fragment of Seasonal Semideciduous Forest - treatment 6). The leaf fraction was the largest contributor to the deposition of litter in all treatments. Litter served as a good environmental indicator that can be used as a tool to support management plans. Key words: Litterfall, forest restoration and Seasonal Semideciduous Forest

Direitos de propriedade e usos econômicos da terra:um estudo de caso de assentamentos de reforma agrária no sul do Pará

This article discusses the Brazilian land problem related to property rights of rural land. After emphasizing the importance of land policies in order to define and distribute rural land properties rights, we show how in Brazil the institutions of rural land registering and cadastering as separated processes debilitates the property rights, making them vulnerable to the effective occupying actions. In order to illustrate it, in this article we analyze Data based in a Case Study of conflict and property rights distributions in an important farming and mining region of southern Para state, in Brazil.

Cariogenicidade do leite materno: mito ou evidência científica

Introduction: Breast-feeding has stood out as health care measure and is part of the Government’s National Health Policy, involving dental professionals. However, it has been suggested that breast milk could be a risk factor for the development of early childhood caries. Objective: The purpose of this report was to search for scientific evidence that would support or refute the statement that breastfeeding is associated with the development of early childhood caries. Method: Medline and SciELO databases were consulted to retrieve studies, ranging from laboratory investigations to epidemiological surveys, which relate breastfeeding to dental caries. The key words ‘breast-feeding’ and ‘dental caries’ were used on the reference search. There was no scientific evidence that could demonstrate a clear relationship between breast milk and cariogenicity. This is attributed to fact that dental caries is a multifactorial disease that is susceptible to multiple confusing factors, among which the early introduction of sucrose to the infant’s diet and late introduction of oral hygiene habits. The dentist should encourage exclusive breast-feeding because, in addition to the undeniable benefits to the child’s physical and psychological health, it contributes to a harmonic facial growth and prevents the development of atypical deglutition and malocclusions, in combination with early introduction of oral hygiene habits and noncariogenic diet. Conclusion: There is no scientific evidence to demonstrate an association between breast-feeding and early childhood caries.

Influencia del número de capas de adhesivo en la conductancia hidraúlica en dentina humana

The aim of this study was to compare the hydraulic conductance in human dentin disks, where 1, 2 or 3 layers of adhesive Single Bond 2(SB2) and Single Bond Universal(SBU) were applied. 84 1 mm. thick(+/- 0.1 mm.) dentin disks were fabricated. Samples were divided into 7 groups (n = 12) Control (without adhesive), A1: one layer of SB2, A2: two layers SB2, A3: three layers SB2, B1: one layer SBU, B2: two layers of SBU, B3: three layers of SBU. The results as averages for the hydraulic conductance of each separate group were: Control (0.0363), A1 (0.0206), A2 (0.0070), A3 (0.0061), B1 (0.0161), B2 (0.0062), B3(0.0056) expressed µl/min.cm2. There is statistically significant difference CH, between the control group and those samples that one coat was applied (p = 0.000) and also between the application of one and two layers (p = 0.000). No difference between the two adhesives (p = 0.434). Summary Key words: Dentin, conductance, difussion adhesive layers.

Pesquisas em animais: uma reflexão bioética

Animal models are an important tool in scientific research. It is known that this practice must be based on bioethical principles in order to impose limits about pain and suffering, or for inspecting proceedings and research site. This study has as aim to evaluate and present current legislation ruling animal research in Brazil, comparing it with other countries, as well as fostering bioethical reflection about this issue. For this, we present current Brazilian legislation and we have carried out international literature review and discussion. The articles were searched in PubMed data base, using the key words "bioethics" and "animal welfare". Nineteen articles from 1997 to 2013 were included. It was concluded the evident contribution of animal research for scientific research in several fields. It is morally relevant for humans, as rational beings, to secure humane treatment to animals contributing to research. The safest way to follow this path is establishing clear norms and studies well designed, involving society for assigning ethical norms. Thus, animal welfare would be guarantee.

O conceito de região e problemas filosóficos: significado epistemológico da história regional e a constituição histórica do espaço liso e do espaço estriado

The concept of region raises two related historical problems. First of all, it concerns the epistemological accomplishment of regional history, since the need to provide a total history, one of the main challenges of the Annales movement, undergoes an impact with the notion of local, so that the overflight of the historic totality becomes nowadays an intensive totality. The historian who overflies the reality is replaced by the wanderer historian. In addition to this epistemological question, we can think about the historical feature of spaces. From an ontological point of view, according to the modes of its composition, as well as from the standpoint of its practical constitution, space can be either smooth or striated. These types of space belong to the Gilles Deleuze s nomadology and their definition might improve the characterization and description of historical spaces with regard to a certain contemporary historiographical movement known as the New Cultural History.Key Words: history;space;nomadism.

Lesbianidades e as referências legitimadoras da sexualidade

This article is part of a master's degree dissertation that studied the way as stigmas and stereotypes regarding lesbianity influence the life, in the sphere of the sexuality, of women that denominate themselves as lesbians, resident in a city in the interior of the State of São Paulo. The stigma here analyzed is that lesbians are women that frustrated with men. We tried to show, through the narratives of the research s participants and basing on gender and feminist studies, how the heteronormativist system naturalizes the masculinity to the men and the sexuality in the masculinity, and how it legitimates speeches about lesbian woman through the heterosexual referential. Also, we tried to show some strategies of the biopoder for the maintenance of that system and, starting from interviews in depth, we presented how the participants of the research (lesbian women) make speeches on that stigma and how they re-significate it through their own narratives. That research was financed by Fundação de Amparo à Pesquisa do Estado de São Paulo FAPESP, and accomplished by the Pos-Graduation Program of the Universidade Estadual Paulista Campus of Assis-SP.Key words: Gender. Sexuality. Lesbianity. Heteronormativity.
