El objetivo de este trabajo fue estudiar la inï€‚uencia de las condiciones de la impresiÃ³n 3D en las propiedades ï€nales del polietileno de alta densidad usando el modelamiento por fusiÃ³n y deposiciÃ³n, FDM. Las muestras de polietileno de alta densidad (PEAD) fueron impresas por el mÃ©todo de modelamiento por fusiÃ³n y deposiciÃ³n (FDM) en tres diferentes temperaturas. Las muestras impresas fueron caracterizadas por difracciÃ³n de rayos X, espectroscopia infrarroja, calorimetrÃ­a diferencial de barrido, anÃ¡lisis termo gravimÃ©trico, ensayo de tracciÃ³n, Ã­ndice de ï€‚uidez y ensayo de contracciÃ³n. Las caracterÃ­sticas tÃ©rmicas, mecÃ¡nicas y estructurales de esas muestras fueron comparadas con las del polietileno de alta densidad original. Los resultados mostraron que las condiciones de impresiÃ³n usadas causaron apenas un leve cambio en las caracterÃ­sticas estructurales de las muestras impresas en relaciÃ³n a la del material original. El enfriamiento desigual en la superï€cie y en el interior de las muestras impresas implicÃ³ en un grado de cristalinidad levemente mayor en el interior en relaciÃ³n a la superfÃ­cie. Un leve cambio en el grado de cristalinidad no fue suï€ciente para causar modiï€caciÃ³n en las propiedades mecÃ¡nicas en relaciÃ³n a la del polietileno de alta densidad original. Otros resultados indicaron que no ocurriÃ³ degradaciÃ³n del material por el efecto de las condiciones de impresiÃ³n 3D utilizadas.

A Modified Range Migration Algorithm for FMCW SAR Signal Processing
Authors: Yake Li , Young Siu O’
Published: December 2019

The range migration algorithm (RMA) is an accurate imaging method for processing synthetic aperture radar (SAR) signals. However, this algorithm requires a big amount of computation when performing Stolt mapping. In high squint and wide beamwidth imaging, this operation also requires big memory size to store the result spectrum after Stolt mapping because the spectrum will be significantly expanded. A modified Stolt mapping that does not expand the signal spectrum while still maintains the processing accuracy is proposed in this paper to improve the efficiency of the RMA when processing frequency modulated continuous wave (FMCW) SAR signals. The modified RMA has roughly the same computational load and required memory size as the range Doppler algorithm (RDA) when processing FMCW SAR data. In extreme cases when the original spectrum is significantly modified by the Stolt mapping, the modified RMA achieves better focusing quality than the traditional RMA. Simulation and real data are used to verify the performance of the proposed RMA.

Безусловно, это сложная задача и потребует систематического и целостного подхода для достижения всех потенциальных выгод.
Dynamics of nitric oxide release in the cardiovascular system.
Authors: Balbatun Aleh , Louka Febee Rophail , Malinski Tadeusz
Published: December 2019

The endothelium plays a critical role in maintaining vascular tone by releasing nitric oxide (NO). Endothelium derived NO diffuses to smooth muscles, triggering their relaxation. The dynamic of NO production is a determining factor in signal transduction. The present studies were designed to elucidate dynamics of NO release from normal and dysfunctional endothelium. The nanosensors (diameter 100-300 nm) exhibiting a response time better than 100 micros and detection limit of 1.0 x 10(-9) mol L(-1) were used for in vitro monitoring of NO release from single endothelial cells from the iliac artery of normotensive (WKY) rats, hypertensive (SHR) rats, and normal and cholesterolemic rabbits. Also, the dynamics and distribution of NO in left ventricular wall of rabbit heart were measured. The rate of NO release was much higher (1200 +/- 50 nmol L(-1) s(-1)) for WKY than for SHR (460 +/- 10 nmol L(-1) s(-1)). Also, the peak NO concentration was about three times higher for WKY than SHR. Similar decrease in the dynamics of NO release was observed for cholesterolemic rabbits. The dynamics of NO release changed dramatically along the wall of rabbit aorta, being highest (0.86 +/- 0.12 micromol L(-1)) for the ascending aorta, and lowest for the iliac aorta (0.48 +/- 0.15 micromol L(-1)). The distribution of NO in the left ventricular wall of rabbit heart was not uniform and varied from 1.23 +/- 0.20 micromol L(-1) (center) to 0.90 +/- 0.15 micromol L(-1) (apex). Both, the maximal concentration and the dynamics of NO release can be useful diagnostic tools in estimating the level of endothelial dysfunction and cardiovascular system efficiency.
Selective splitting of 3'-adenylated dinucleoside polyphosphates by specific enzymes degrading dinucleoside polyphosphates.
Authors: Guranowski Andrzej , Sillero Antonio , Günther Sillero María Antonia
Published: December 2019

Several 3'-[(32)P]adenylated dinucleoside polyphosphates (Np(n)N'p*As) were synthesized by the use of poly(A) polymerase (Sillero MAG et al., 2001, Eur J Biochem.; 268: 3605-11) and three of them, ApppA[(32)P]A or ApppAp*A, AppppAp*A and GppppGp*A, were tested as potential substrates of different dinucleoside polyphosphate degrading enzymes. Human (asymmetrical) dinucleoside tetraphosphatase (EC 3.6.1.17) acted almost randomly on both AppppAp*A, yielding approximately equal amounts of pppA + pAp*A and pA + pppAp*A, and GppppGp*, yielding pppG + pGp*A and pG + pppGp*A. Narrow-leafed lupin (Lupinus angustifolius) tetraphosphatase acted preferentially on the dinucleotide unmodified end of both AppppAp*A (yielding 90% of pppA + pAp*A and 10 % of pA + pppAp*A) and GppppGp*A (yielding 89% pppG + pGp*A and 11% of pG + pppGp*A). (Symmetrical) dinucleoside tetraphosphatase (EC 3.6.1.41) from Escherichia coli hydrolyzed AppppAp*A and GppppGp*A producing equal amounts of ppA + ppAp*A and ppG + ppGp*A, respectively, and, to a lesser extent, ApppAp*A producing pA + ppAp*A. Two dinucleoside triphosphatases (EC 3.6.1.29) (the human Fhit protein and the enzyme from yellow lupin (Lupinus luteus)) and dinucleoside tetraphosphate phosphorylase (EC 2.7.7.53) from Saccharomyces cerevisiae did not degrade the three 3'-adenylated dinucleoside polyphosphates tested.

Published: December 2019

Immunological and biochemical evidence has been obtained for an interaction of maize protein phosphatase 2A (PP2A) holoenzyme with tubulin. Tubulin co-purifies with maize seedling PP2A. Affinity chromatography of the maize PP2A preparation on immobilized tubulin revealed two peaks of phosphorylase alpha phosphatase activity. In one of the peaks, the catalytic (C) and constant regulatory (A) subunits of PP2A were identified by Western blotting. The subunits (C and A) of PP2A were co-immunoprecipitated from maize seedlings homogenate by an anti-alpha-tubulin antibody. The interaction of plant PP2A with tubulin indicates a possible role of reversible protein phosphorylation in the dynamic structure of plant cytoskeleton.
Poly(ADP-ribose) polymerase in base excision repair: always engaged, but not essential for DNA damage processing.
Authors: Allinson Sarah L , Dianova Irina I , Dianov Grigory L
Published: December 2019

Poly(ADP-ribose) polymerase (PARP-1) is an abundant nuclear protein with a high affinity for single- and double-strand DNA breaks. Its binding to strand breaks promotes catalysis of the covalent modification of nuclear proteins with poly(ADP-ribose) synthesised from NAD(+). PARP-1-knockout cells are extremely sensitive to alkylating agents, suggesting the involvement of PARP-1 in base excision repair; however, its role remains unclear. We investigated the dependence of base excision repair pathways on PARP-1 and NAD(+) using whole cell extracts derived from normal and PARP-1 deficient mouse cells and DNA substrates containing abasic sites. In normal extracts the rate of repair was highly dependent on NAD(+). We found that in the absence of NAD(+) repair was slowed down 4-6-fold after incision of the abasic site. We also established that in extracts from PARP-1 deficient mouse cells, repair of both regular and reduced abasic sites was increased with respect to normal extracts and was NAD(+)-independent, suggesting that in both short- and long-patch BER PARP-1 slows down, rather than stimulates, the repair reaction. Our data support the proposal that PARP-1 does not play a major role in catalysis of DNA damage processing via either base excision repair pathway.
High levels of bulky DNA adducts in human sperm correlate with impaired fertility.
Authors: Horak Stanisław , Polańska Joanna , Widłak Piotr
Published: December 2019

Progressive decline in fertility and sperm quality has been reported over the last few decades, especially in industrialized nations. It has been proposed that exposure to factors that induce damage in DNA of spermatogenic cells may significantly contribute to impaired fertility. Here, the (32)P-postlabelling method was used to analyze the levels of bulky DNA adducts in sperm cells in a group of 179 volunteers, either healthy subjects or patients with an impaired fertility. The levels of DNA adducts were 1.35-fold higher in the infertile group as compared to healthy individuals (P = 0.012). Similarly, a significant negative correlation between the levels of DNA adducts and measures of semen quality (sperm concentration and motility) has been observed (P
Labile iron pool correlates with iron content in the nucleus and the formation of oxidative DNA damage in mouse lymphoma L5178Y cell lines.
Authors: Kruszewski Marcin , Iwaneńko Teresa
Published: December 2019

Labile iron pool (LIP) constitutes a crossroad of metabolic pathways of iron-containing compounds and is midway between the cellular need for iron, its uptake and storage. In this study we investigated oxidative DNA damage in relation to the labile iron pool in a pair of mouse lymphoma L5178Y (LY) sublines (LY-R and LY-S) differing in sensitivity to hydrogen peroxide. The LY-R cells, which are hydrogen peroxide-sensitive, contain 3 times more labile iron than the hydrogen peroxide-resistant LY-S cells. Using the comet assay, we compared total DNA breakage in the studied cell lines treated with hydrogen peroxide (25 microM for 30 min at 4 degrees C). More DNA damage was found in LY-R cells than in LY-S cells. We also compared the levels of DNA lesions sensitive to specific DNA repair enzymes in both cell lines treated with H(2)O(2). The levels of endonuclease III-sensitive sites and Fapy-DNA glycosylase-sensitive sites were found to be higher in LY-R cells than in LY-S cells. Our data suggest that the sensitivity of LY-R cells to H(2)O(2) is partially caused by the higher yield of oxidative DNA damage, as compared to that in LY-S cells. The critical factor appears to be the availability of transition metal ions that take part in the OH radical-generating Fenton reaction (very likely in the form of LIP).
Expression in Escherichia coli of human ARHGAP6 gene and purification of His-tagged recombinant protein.
Authors: Ochocka Anna-Maria , Czyzewska Marzena , Pawełczyk Tadeusz
Published: December 2019

In this report we describe cloning and expression of human Rho GTPase activating protein (ARHGAP6) isoform 4 in Escherichia coli cells as a fusion protein with 6xHis. We cloned the ARHGAP6 cDNA into the bacterial expression vector pPROEX-1. Induction of the 6xHis-ARHGAP6 protein in BL21(DE3) and DH5alpha cells caused lysis of the cells irrespective of the kind of culture medium used. Successful expression of the fusion protein was obtained in the MC4100Deltaibp mutant strain lacking the small heat-shock proteins IbpA and IbpB. Reasonable yield was obtained when the cells were cultured in Terrific Broth + 1% glucose medium at 22 degrees C for 16 h. The optimal cell density for expression of soluble 6xHis-ARHGAP6 protein was at A(600) about 0.5. Under these conditions over 90% of the fusion protein was present in a soluble form. The 6xHis-ARHGAP6 protein was purified to near homogeneity by a two step procedure comprising chromatography on Ni-nitrilotriacetate and cation exchange columns. The expression system and purification procedure employed made it possible to obtain 1-2 mg of pure 6xHis-ARHGAP6 protein from 300 ml (1.5 g of cells) of E. coli culture.
A novel mutation A1270G of the EDA1 gene causing Tyr343Cys substitution in ectodysplasin-A in a family with anhidrotic ectodermal dysplasia.
Authors: Kobielak Agnieszka , Kobielak Krzysztof , Biedziak Barbara , Trzeciak Wieslaw H
Published: December 2019

The structure of the EDA1 gene was investigated in a patient with anhidrotic ectodermal dysplasia. Sequence analysis revealed a novel A1270G transition in exon 9 of the EDA1 gene in the patient and his uncle, whereas the patient's mother and grandmother were heterozygotes. This mutation resulted in Tyr343Cys substitution in the extracellular domain of the EDA1 gene product - ectodysplasin-A. The additional Cys343 was located between Cys332 and Cys346 and formed with Cys352 a cluster of four closely situated residues that could potentially form disulfide bonds. This mutation might affect the tertiary structure of the receptor-binding domain of ectodysplasin-A and precipitate the clinical symptoms of anhidrotic ectodermal dysplasia.

Published: December 2019

Background: Preeclampsia is considered as a serious life-threatening condition that could affect both maternal and fetal outcome. Many studies have examined the association of nutritional factors with the incidence of preeclampsia. However, little is known about the possible role of vitamin D in the development of preeclampsia among the Iranian population.
Objective: The aim of the present study was to evaluate the association between vitamin D status and preeclampsia.
Materials and Methods: A total of 120 pregnant women who were referred to Kamali and Alborz General Hospital located in the Karaj City were enrolled in this study and categorized into preeclamptic and control groups (n = 60/each). The clinical details of patients such as demographic characteristics and laboratory findings were obtained from the patients. The serum levels of vitamin D, calcium, phosphorus, and parathormone were also measured. Multivariate logistic regression analysis was used to assess for independent predictors of preeclampsia.
Results: The mean age among pregnant women with preeclampsia and control group were 31.48 ± 5.25 and 29.01 ± 5.28, respectively. The mean body mass index among the preeclamptic group was 27.92 ± 4.98, which was significantly higher compared to the control group (p < 0.001). The serum vitamin D levels were significantly lower in women with preeclampsia compared to the control subjects (p = 0.007). Moreover, no correlation between vitamin D deficiency and predisposing factors of preeclampsia was observed after adjusting for confounding factors.
Conclusion: Our study revealed that serum vitamin D level is significantly lower in among the pregnant women diagnosed with preeclampsia compared to the healthy subjects. However, no correlation was observed between the vitamin D status and the risk of preeclampsia development.

Published: December 2019

Background: Cardiovascular diseases could be preventable; as a result, understanding the risk factors was regarded as the major priority for healthcare providers.
Objective: The main objective of this research was to achieve a deeper insight into the effect of long-term use of low-dose oral contraceptive pills (OCP) on the risk factors of cardiovascular diseases.
Materials and Methods: This research was a retrospective cohort conducted (historical and prospectively) conducted on 100 women with normal menstrual cycles aged 15 to 35 yr, who were referred to the healthcare centers in Yazd, Iran. The participants were categorized into two groups: The OCP group was consuming the pills for 3, 4-23, and 24-36 months, and the non-OCP group. Participants were followed up for a minimum of 3 months and a maximum of six months.
Results: The highest level of low-density lipoprotein (LDL), homocysteine, cholesterol, triglyceride levels, and systolic blood pressure was observed in the OCP group in the duration of 24 to 36 months. The Tukey’s test demonstrated that there were comprehensible differences in the LDL (p = 0.01), cholesterol (p = 0.01), triglyceride (p < 0.001), and homocysteine levels (p < 0.001), also systolic blood pressure (p = 0.04).
Conclusion: It was realized that the long-term consumption of low-dose OCP can augment the incidence of some risk factors (systolic blood pressure, homocysteine levels, cholesterol, LDL-c, and triglyceride) and lead to developing cardiovascular diseases amongst the healthy women.

In this study we examined the effects of conventional agricultural treatment with plowing and no-till treatment on the physical, chemical and microbiological properties of agro-transformed sod-podzolic loamy soil. Soil was sampled in eightfold spatial replication from the arable layers (0–10, 10– 20, 20–30 cm) of field No. 2 of the long-term field experiment of the Center for Precision Agriculture of the Russian State Agrarian University in June, 2018. The crop type on the field No. 2 was vetch and oat mix. Moisture content, water holding capacity, pH, percentage of carbon and nitrogen were determined. The NDVI vegetation index was measured using GreenSeeker HandHeld and used to estimate the plant development intensity. Microbiological properties were assessed by selective plate counts. The abundance and activity were estimated for the next ecological and trophic groups of microorganisms: heterotrophic ammonifiers, aerobic and anaerobic nitrogen-fixing agents, denitrifiers, oligotrophs, cellulolytics. The vegetation index NDVI was higher for plants growing on the plowed part of the field. The differences in microbiological properties when comparing soil samples under no-till and under plowing were insignificant (by t-test for the independent groups comparison). In no-till samples a greater number of micromycetes, including cellulolytic and phytopathogenic, was observed compared to conventional treatment. Profile distributions of bacterial and fungal gene abundances were similar for both treatments according to the paired comparison of samples from different layers. The similarity in microbiological properties was found in the condition of a higher moisture content of the arable layer of the soil and a higher percentage of nitrogen were revealed in the soil under no-till compared with the soil treated by plowing.
Agents of soil salinization in “Chervlenoe” and “Duboovrazhniy” plots of the Svetloyarsk irrigation system
Authors: Kravchenko E. I.
Published: December 2019

The agents that determine the soil salinity of the key plots “Chervlenoe” and “Duboovrazhniy” of the Svetloyarsk irrigation system (Volgograd region) are studied. We carried out a multifactor analysis of the toxic salts amount variance depending on the following agents: relief, vegetation, parent material and irrigation method, the water extract (1 : 5) being used. It was found that the factors determining the degree of soil salinity in terms of the amount of toxic salts in both cases is parent material. Its contribution into the total variance was more than 80 % for both studied plots. On the plot “Duboovrazhniy” relief also turned out to be a significant factor. Anthropogenic factor – the method of irrigation – was insignificant. The graphs of cumulative frequencies of the occurrence of salinity levels were constructed for soil layers of 0–30 cm, 30–100 cm, 100–150 cm, 150–200 cm. The top soil layer of 0–30 cm is almost non-saline in both areas. On the “Chervlenoe” plot there are strong and very strong degrees of soil salinization; in general, this site is characterized by higher toxic salts amount compared to the “Duboovrazhniy” plot.

The article deals with the features of soil-agrochemical inspection of the nursery area with the use of geoinformation technologies. The purpose of this work was to conduct a soil survey of arable sod-podzolic medium - or light-loamy soils of the territory of the forest nursery, as well as estimation of production area contamination with weeds. The peculiarity of this study was the fact that the process of collection, systematization and processing of all compiled information was focused on the use of modern geographic information systems. Survey points were chosen in coordination with the administration of the nursery and were precised according to the actual space images. Geographical reference of testing points was carried out using global positioning technologies (GPS, GLONASS) based on the NextGIS mobile application (Android OS). Photofixation of nursery fields was performed by means of geotagging technologies, which allow implementation of the obtained graphic information directly into the geographic information system (GIS). The soil samples collected in the field were analyzed in the soil laboratory in order to determine the main indicators of soil fertility. On the basis of the received data the cartograms were developed by means of GIS, which provide information on the main nutrients content in the soil of nursery fields as well as on the most important indicators characterizing the soil absorbing complex (soil acidity, degree of base saturation, etc.). The study of weed infestation allowed developing the thematic map representing the weeds propagation on the nursery fields. All collected information was combined into a comprehensive geographic information system developed on the basis of Quantum GIS shell. As a result, the developed GIS will contribute to operational monitoring of soil fertility and ensure informational support for agricultural machinery applied in the nursery for growing planting material.

Published: December 2019

O objeto de estudo deste artigo são as instituições universitárias do estado do Paraná e tem como objetivo analisar a formação e atuação dos coordenadores de curso. Argumenta-se que a coordenação de cursos de graduação nas universidades deve compreender uma formação que contribua com uma gestão democrática, que se torna fundamental no contexto das transformações políticas e econômicas que vêm sendo implantadas nas últimas décadas no país, com ênfase em uma gestão gerencial. Preservar as instituições, cuja existência é fundamental para a democracia no país, é fundamental, em especial, nestes tempos em que se vive uma crise das democracias. Para tanto, foi desenvolvida uma investigação com abordagem qualitativa, mediante análise da legislação vigente sobre a educação superior, dados do Censo da Educação Superior e aplicação de questionário aos coordenadores de curso. São apresentados dados sobre as características das universidades e aspectos relacionados à formação continuada e à atuação e à escolha dos coordenadores de curso, contemplando uma análise sobre a gestão democrática.
A normatização do direito à educação nos países do Mercosul
Authors: Souza Kellcia Rezende , Kerbauy Maria Teresa Miceli
Published: December 2019

O estudo analisa a proteção normativa do direito à educação básica nos países-membros do Mercado Comum do Sul (Mercosul), que são: Argentina, Brasil, Paraguai, Uruguai e Venezuela. Para tanto, foi realizada, mediante estudo comparado, uma pesquisa bibliográfica e documental (Constituições e Legislações educacionais vigentes) com enfoque qualitativo. Denota-se que o ordenamento legal brasileiro, paraguaio e venezuelano evidencia elementos mais específicos e contundentes para a garantia normativa do direito educacional. A Constituição Argentina, bem como a Uruguaia, é bastante lacônica no que tange aos marcos legais do direito à educação. Esse quadro demonstrou que há a consolidação de um ordenamento jurídico educacional no contexto do Mercosul, mas que ainda carece de normativas que assegurem uma proteção mais ampla ao direito à educação. Nesse viés, é imperativo afirmar que, devido à abrangência do tema, reconhecemos que há um extenso campo de investigação aberto para que se possa aprofundar e produzir conhecimento novo sobre essa temática.
Paulo Freire con glitter y pañuelo verde: notas cuir para educadores
Authors: Ramallo Francisco
Published: December 2019

En las últimas tres décadas la movilización de las teorías cuir cuestionaron la idea de un sujeto autónomo, la pedagogía intelectualizada – en su desconexión con los afectos y los cuerpos –, la linealidad de la mediación, la racionalidad evolucionista, la retórica salvacionista del humanismo y la evangelización de la positividad y la esperanza. Este ensayo es un homenaje – respetuoso e irreverente – a Paulo Freire, en cuyas sombras me propongo aventurar una provocación que resalta la necesidad de enunciar saberes sensibles a la sobrevivencia de nuestros afectos y cuerpos en la teoría de la educación, de allí que hoy mancho al maestro con glitter y con un pañuelo verde. Con este propósito transito tres movimientos. En el primero, resalto la intención de contaminar la imagen inmaculada del pedagogo latinoamericano como práctica de descomposición de los saberes autorizados en la pedagogía. En el segundo movimiento mapeo brevemente una serie de narrativas que descentran al sujeto moderno de la pedagogía, subrayando el cometido cuir de desconocer su tecnología evolutiva y su imprevisible racionalidad. En el tercer movimiento recojo una serie de lecturas, que a la vez valorizan y cuestionan la obra de Paulo Freire. Por todo esto, argumento – como forma de ir contra uno mismo – a favor de un dislocamiento de las lecturas rectas de la pedagogía crítica, una necesidad cívica frente a la actual demanda por una educación sexual.

Authors: Glynos Jason , Oliveira Gustavo Gilson Sousa de , Burity Joanildo
Published: December 2019

Interview with Professor Jason Glynos, co-director of the Center for Ideology and Discourse Analysis (CIDA) at the University of Essex, UK, conducted by professors Joanildo Burity (FUNDAJ) and Gustavo Gilson Oliveira (UFPE). The interview explores the contours, the conceptual framework and the analytic strategies being developed in relation to the so-called Critical Fantasy Studies’ field, associated with his recent work. It seeks to investigate, above all, how these concepts and strategies have contributed and may further contribute to broadening our understanding and deepening our analysis of the spread of neoliberal logics and the emergence of “new” conservative logics in the contemporary social and political scene, particularly in the field of education.

Published: December 2019

As atividades práticas podem contribuir de forma atraente e significativa para a eficácia no processo de ensino e aprendizagem em Ciências. Em vista disso, o presente estudo se propôs a analisar como os professores de Ciências concebem a utilização de atividades práticas nas suas aulas e quais as estratégias que empregam. A fim de realizarmos essa investigação, optamos por uma pesquisa qualitativa (particularmente um estudo de caso) em que acompanhamos, por meio da observação das aulas e de entrevistas semiestruturadas, o trabalho de quatro professores de Ciências de uma escola estadual de tempo integral, localizada na cidade de São Paulo. Apoiamo-nos, para isso, na revisão literária que congrega o ensino de Ciências numa perspectiva histórica e social; a formação e a prática docente na área de Ciências; e o conceito de atividades práticas. Os resultados obtidos mostraram que, na visão dos professores, as atividades práticas são importantes para estimular a observação e a curiosidade, permitindo maior compreensão dos conteúdos e melhoria na aprendizagem científica.

Authors: Colussi Angela , Zwierewicz Marlene , Simão Vera Lúcia
Published: December 2019

Incluir estudantes com Transtornos do Espectro Autista (TEA) e estimular sua oralidade constitui um dos grandes desafios da educação atual, especialmente em razão das especificidades em relação à comunicação, à interação e aos interesses que apresentam. Esta pesquisa teve como objetivo apresentar como produto educacional estratégias para inclusão de estudantes com TEA no contexto escolar, classificando-as de acordo com o potencial que oferecem para o desenvolvimento de habilidades relacionadas à oralidade no uso da língua inglesa, previstas pela Base Nacional Curricular Comum (BNCC) para o 6° ano do Ensino Fundamental. Com base nas pesquisas documental, bibliográfica e comparativa e na abordagem qualitativa, os dados foram coletados na BNCC e em artigos científicos voltados à inclusão de estudantes com TEA. Além das estratégias gerais para a inclusão, a aproximação com as habilidades do eixo oralidade possibilitou situar a Interação Social Mediada em Ambientes Digitais e o Ateliê de História como opções para estimular a interação discursiva, a Comunicação Alternativa e Ampliada (CAA) para estimular a compreensão oral e o Programa de Habilidades Comunicativas Verbais (HCV) e a Modelagem de Vídeo (VD) para estimular a produção oral. Sugere-se que a exploração das referidas estratégias se constitua em um trabalho personalizado, focado na realidade e no grau de complexidade das condições de cada estudante com TEA.
A educação escolar nas reservas indígenas: um olhar a partir do acervo documental do Serviço de Proteção ao Índio (SPI)
Authors: Vieira Carlos Magno Naglis , Ximenes Lenir Gomes , Ferreira Eva Maria Luiz
Published: December 2019

O texto apresenta uma discussão acerca da educação escolar nas Reservas Indígenas Guarani e Kaiowá, a partir de documentos históricos produzidos no contexto de atuação do Serviço de Proteção ao Índio (SPI), consultados no Centro de Documentação Indígena Antônio Brand (CEDOC) (no Núcleo de Estudos e Pesquisa das Populações Indígenas [NEPPI], na Universidade Católica Dom Bosco [UCDB]) e no acervo virtual do Museu do Índio/FUNAI. Os documentos analisados neste artigo são da 5ª Inspetoria Regional do SPI/I. R. 5, referentes ao sul de Mato Grosso (atual Mato Grosso do Sul), mais especificamente ao Posto Indígena José Bonifácio, no município de Caarapó, em território dos Guarani e Kaiowá. A análise documental evidencia o paradigma assimilacionista que norteou a política indigenista do Estado brasileiro apresentando os ideais reguladores para “a formação do cidadão como sujeito de direito” e direcionando os objetivos da presença da educação escolar nas áreas de abrangência do SPI, órgão que atuou entre 1910 e 1967.

Published: December 2019

O Sistema Universidade Aberta do Brasil (UAB) foi instituído pelo Decreto n. 5.800, de 8 de junho de 2006, e tem como principal finalidade a formação de professores para atuar na educação básica. O presente artigo apresenta o resultado de um estudo que buscou analisar os efeitos da política desenvolvida pela UAB na perspectiva dos egressos do curso de Pedagogia, na modalidade de Educação a Distância (EaD), da Universidade Estadual de Maringá (UEM), turma 2009. Trata-se de uma pesquisa qualitativa vinculada ao campo das políticas educacionais, que engloba estudos teóricos e empíricos. Os resultados indicam que os benefícios obtidos posteriormente à realização do curso de Pedagogia EaD/UEM, no âmbito do Sistema UAB, ultrapassam a expansão do número de vagas no ensino superior. Constatou-se que ocorreram melhorias na vida profissional e pessoal dos sujeitos pesquisados.
Produções científicas do GT 16 Educação e Comunicação da ANPEd entre 2011 e 2017: contribuições da análise bibliométrica para a qualificação da área
Authors: Echalar Jhonny David , Lima Daniela da Costa Britto Pereira , Alonso Kátia Morosov

Os dados e discussões que constituem este trabalho são oriundos de parte dos resultados de uma pesquisa em desenvolvimento cujo objetivo é compreender as perspectivas teóricas mais utilizadas nas discussões dos trabalhos aprovados no Grupo de Trabalho (GT) 16 – Educação e Comunicação, em eventos nacionais e regionais da Associação Nacional de Pesquisa em Educação (ANPEd). Para tal realizou-se o levantamento dos trabalhos disponíveis nas páginas online desses eventos, enquanto a sistematização e a análise dos dados foram alicerçadas por instrumentos das pesquisas bibliométrica e documental. O levantamento bibliográfico utilizou diferentes softwares para coleta, organização e análise dos dados, configurando-se a pesquisa como mista. Essa metodologia possibilitou observar uma maior representatividade das regiões Sul e Sudeste nos encontros nacionais, assim como um maior número de citações de autores dessas mesmas regiões nas referências analisadas. No que se refere aos encontros regionais, observa-se certa característica regionalista entre os autores-referência, mas também a inserção de outros considerados como citação indispensável, tais como Paulo Freire e Pierre Lévy, por exemplo. Em comum, os trabalhos do GT 16 utilizam mais expressivamente referências do campo da Comunicação, em relação ao da Educação, e evidenciam uma maior proximidade entre os referenciais teóricos utilizados por pesquisadores das regiões Sul e Sudeste nos encontros nacionais da Associação.
