Educar e ensinar: dois contextos, múltiplas aprendizagens: relatório final

O presente relatório final surgiu no âmbito das Unidades Curriculares de Prática Educativa I e Prática Educativa II, integrantes do plano de estudos do Mestrado em Educação Pré-Escolar e Ensino do 1.º Ciclo do Ensino Básico1, da Escola Superior de Educação de Coimbra2. Este tem, como principal propósito, sintetizar o meu percurso formativo, e em particular refletir a sequência e a complexidade das aprendizagens mais significativas realizadas nos estágios em Educação Pré-Escolar e em 1.º CEB. Quer a observação, quer a reflexão foram etapas imprescindíveis, uma vez que permitiram identificar problemas que, no dia-a-dia, se colocavam aos intervenientes no processo de ensino e de aprendizagem, detetar situações específicas, como, crianças com necessidades educativas especiais, em risco, etc., que mereciam uma atenção particular na gestão do currículo e perceber as dinâmicas organizacionais e metodológicas, nomeadamente, a organização do trabalho (das instituições e dos grupos), as metodologias da educadora e professor cooperantes e as interações entre pares (criança-criança, criança-educadora/professor, professor/educadora-crianças). As aprendizagens mais significativas, também designadas de Experiências-Chave, passaram pelo valor da documentação pedagógica para as aprendizagens iniciais, pela importância do espaço exterior para o desenvolvimento físico, social e cognitivo das crianças, pela relevância da diferenciação pedagógica para o sucesso escolar, pelo prestígio das tecnologias de informação e comunicação no processo de ensino e aprendizagem, pela articulação curricular entre a Educação Pré-Escolar e o 1.º CEB e por fim, pela implementação da metodologia, Abordagem de Mosaico em Educação Pré-escolar. No final de cada delas foi sempre elaborada uma análise crítico-reflexiva, tendo em conta os saberes adquiridos e as competências desenvolvidas ao longo da formação inicial.

CONCEPÇÕES DE GEOGRAFIA, ESPAÇO E TERRITÓRIO NOS ANAIS DO IV SEMINÁRIO ESTADUAL DE ESTUDOS TERRITORIAIS E II SEMINÁRIO NACIONAL SOBRE MÚLTIPLAS TERRITORIALIDADES

Nosso objetivo principal é compreender as diferentes concepções de geografia, espaço geográfico e território utilizadas pelos autores dos textos apresentados como comunicações livres no IV Seminário Estadual de Estudos Territoriais e II Seminário Nacional sobre Múltiplas Territorialidades, visando compreender as tendências teórico-metodológicas atuais da geografia brasileira. Os procedimentos utilizados na pesquisa são: a) seleção dos textos dos Anais que foram analisados (51 de um total de 72 trabalhos apresentados e publicados); b) leitura e fichamento dos textos escolhidos; c) elaboração de um quadro síntese para cada texto lido e analisado; d) comparação e interpretação das informações extraídas de cada texto; e) identificação das categorias utilizadas, referências e concepções, reconstruindo caminhos percorridos pelos autores; f) identificação e análise das concepções de geografia, espaço e território; g) redação dos relatórios e textos para publicação. Estes procedimentos estão fundamentados numa abordagem espaço-temporal da construção do pensamento e do conhecimento geográfico, considerando-se os textos selecionados de autores de diferentes lugares do Brasil.

Neurological evaluation of neonates with intraventricular and periventricular hemorrhage

We studied the clinical aspects of 100 consecutive premature newborns with and without intraventricular and periventricular hemorrhage (IPVH).The diagnosis of IPVH was obtained by ultrasonic scans of the skull during the first week of life and at the age of one month. Forty eight percent of newborns with IPVH had abnormal results, and there was a significant correlation with the neurological evaluation in 85% of the infants. The probability of normality for a child with no associated brain abnormalities was 72%, whereas for a child of the same gestational age with associated brain abnormalities was 48.7%.

Influência do processo de secagem na qualidade do cogumelo shiitake

Edible mushroom are highly perishable foods. Drying is an alternative to provide safe storage. In this work, the effects of some drying parameters on the quality of Shiitake mushroom were investigated: geometry of the raw material (whole and sliced), drying temperature (50 °C and 70 ºC) and final moisture content (5% and 15% wb). Experimental kinetics of drying was built and color and texture analyses were done in fresh and in rehydrated dried product. The effect of parameters was evaluated by analysis of variance and test of multiple comparisons. Drying kinetics showed that drying happened in falling-rate period and sliced mushroom dried at 70 ºC required lesser drying time than other treatments. Mushroom dried at 70 ºC showed less darkening. Drying time affected mushroom quality, evaluated by great hardness, gummosis and darkening.

Modelos de regressão lineares para estimativa de produtividade da soja no oeste do Paraná, utilizando dados espectrais

The main objective of this work was to evaluate the linear regression between spectral response and soybean yield in regional scale. In this study were monitored 36 municipalities from the west region of the states of Parana using five images of Landsat 5/TM during 2004/05 season. The spectral response was converted in physical values, apparent and surface reflectances, by radiometric transformation and atmospheric corrections and both used to calculate NDVI and GVI vegetation indices. Those ones were compared by multiple and simple regression with government official yield values (IBGE). Diagnostic processing method to identify influents values or collinearity was applied to the data too. The results showed that the mean surface reflectance value from all images was more correlated with yield than individual dates. Further, the multiple regressions using all dates and both vegetation indices gave better results than simple regression.

Tissue culture of Cecropia glaziovii Sneth (urticaceae): vegetative micropropagation and plant regeneration from callus

Cecropia glaziovii is a tree with used in Brazilian popular medicine. Methods allowing the clonal propagation of this species are of great interest for superior genotype multiplication and perpetuation. For this reason, we examined the effect of different culture media and different types of explants on adventitious shoot regeneration from callus and buds of C. glaziovii. Leaves, petioles and stipules obtained from aseptically grown seedlings or from pre-sterilized plants were used to initiate cultures. Adventitious shoot regeneration was achieved when apical and axillary buds were inoculated on gelled Murashige & Skoog (MS) medium supplemented with 6-benzylaminopurine alone (BAP) (1.0, 5.0 or 10.0 mg L-1) or combined with -naphthalene acetic acid (NAA) (1.0 or 2.0 mg L-1), after 40 days of culture. Best callus production was obtained after 30 days of petioles' culture on gelled MS medium with 2,4 dichlorophenoxyacetic acid (2,4-D) (5.0 mg L-1) combined with BAP (1.0 mg L-1). Successful shoot regeneration from callus was achieved when MS medium supplemented with zeatin (ZEA) (0.1 mg L-1) alone or combined with 2,4-D (1.0 or 5.0 mg L-1) was inoculated with friable callus obtained from petioles. All shoots were rooted by inoculation on MS medium supplemented with indole-3-acetic acid (IAA) (1.0 mg L-1). Rooted plants transferred to potting soil were successfully established. All in vitro regenerated plantlets showed to be normal, without morphological variations, being also identical to the source plant. Our study has shown that C. glaziovii can be propagated by tissue culture methods, allowing large scale multiplication of superior plants for pharmacological purposes.

Multifunctional role of steroidogenic factor 1 and disorders of sex development

Disorders of sex development (DSD) involve several conditions that result from abnormalities during gonadal determination and differentiation. Some of these disorders may manifest at birth by ambiguous genitalia; others are diagnosed only at puberty, by the delayed onset of secondary sexual characteristics. Sex determination and differentiation in humans are processes that involve the interaction of several genes such as WT1, NR5A1, NR0B1, SOX9, among others, in the testicular pathway, and WNT4, DAX1, FOXL2 and RSPO1, in the ovarian pathway. One of the major proteins in mammalian gonadal differentiation is the steroidogenic nuclear receptor factor 1 (SF1). This review will cover some of the most recent data on SF1 functional roles and findings related to mutations in its coding gene, NR5A1.

Candidíase sistêmica com localização encefálica: estudo anátomo-clínico de cinco casos

Central nervous system involvement in Candida septicaemia is rare and not more than four cases have been published in Brazil. Five new cases of systemic candidiasis with cerebral lesions are reported. All patients (four adults and a child) had serious underlying diseases and were submitted to heavy long-term antibiotic therapy with multiple drugs. Seizures in one case and neck stiffness in another were the only neurologic signs that could be attributed to candidiasis. In no case were the lesions severe enough to be considered an immediate cause of death. In three patients, no macroscopic changes were evident in the brain, but microabscesses and granulomata were observed on microscopical examination; another patient had two gross areas with necrotic and haemorrhagic appearance in the cerebral hemispheres; the child had only two microscopic granulomata. The aetiological agent was demonstrated by Grocott's methenamine silver technique in all cases. Involvement of organs other than the central nervous system could be demonstrated in three autopsies. Discussion is confined mainly to such aspects as the contributory factors in the pathogenesis of systemic candidiasis as well as the marked rise in the incidence of this condition in the past few decades. It is suggested that the frequence of monilial septicaemia in Brazil may be far more serious than apparent from the scarcity of reported cases.

Neuronal Ceroid-lipofuscinosis with prominent chorea and without visual manifestations: a case report

A case of neuronal ceroid-lipofuscinosis (NCL) is reported in a 11-year-old girl, whose main symptoms were progressive dementia since the age of 4 years and choreic movements since age 10. Seizures, myoclonus and visual deterioration were absent and optic fundi were normal. A cerebral biopsy disclosed two basic types of stored substance in the cytoplasm of neurons: a) severely balloned nerve cells in cortical layers HI and V contained a non-autofluorescent material, which stained with PAS and Sudan Black B in frozen, but not in paraffin sections; ultrastructurally, these neurons showed abundant corpuscles similar to the membranous cytoplasmic bodies of Tay-Sachs disease and, in smaller amounts, also zebra bodies; b) slightly distended or non-distended neurons in all layers contained lipopigment granules, which were autofluorescent, PAS-positive and sudanophil in both frozen and paraffin sections; their ultrastructure was closely comparable to that of lipofuscin. Similar bodies were found in the swollen segments of axons and in a few astrocytes and endothelial cells. The histochemical and ultrastructural demonstration of large amounts of lipopigments allows a presumptive classification of the case as NCL. However, the presence of involuntary movements, the absence of visual disturbances and the unusual ultrastructural features place the patient into a small heterogeneous group within the NCL. A better classification of such unique instances of the disease must await elucidation of the basic enzymatic defects.

Familial glioblastoma

The authors describe a family with three members affected by glioblastoma. The proband patient, a 7 year-old girl, developed a rare complication, a pulmonary metastasis. Chromosomal analysis of her peripheral blood lymphocytes showed a normal karyotype (46, XX), without structural abnormalities. Cytogenetic study of the tumor cells disclosed several abnormalities: 46, XX, 7q - / 46, XX, -2, 4p-, 7p-, +15/ 46, XX. Some aspects about genetics of glial neoplasms are discussed.
