Aprendizagem significativa: uma proposta de ensino e aprendizagem da geometria euclidiana espacial no ensino médio

This dissertation is a research based on the Meaningful Learning Theory, with students from the second year of High School, in the city named Capinzal do Norte, state of Maranhão. The pedagogic approach of this research focuses on what to do and how to do so students can better grasp knowledge inherent to the Euclidean Special Geometry in a more meaningful and changing way, also that information may be kept longer in their brain, so it can last longer in the present and future. The methodological strategy adopted was the research-action, followed by the constant observance of a researcher on the matter with the purpose to ensure consistent results, which come from the use of a variety of data collector instruments, such as: Concept Maps, manipulatives, educational softwares and application of evaluative tests, besides the observations made throughout the process of investigation and the diagnosis itself. It is all due to the fact that we rely on the premise that knowledge is assimilated in particular and idiosyncratic ways, which means each and every student learns in different ways and in different periods of time. That is why it is so important to develop diversified methodologies to the same subject. This research adds to the other ones related to the theoretical frameworks of the Meaningful Learning Theory, of Concept Maps, of the use of technology on the educational process and of manipulatives, which purpose is to connect their common dots. This pedagogical intervention also focuses on the construction of the educational orientations with applicability directly on class, directed specially by the Mathematics teacher of the basic education, who might use them during your teaching practice. Such guidelines established here as an educational product aim to follow the Theory's assumptions that serves as basis to this research, thus becoming an educational element with a relevant significance. The results, with which we are faced, proved overwhelming to the proposed objectives in terms of learning, which were evident in the construction of Conceptual Maps, as well as in the use of Concrete Materials, in addition to serving as a motivational element to participating students of research. The results obtained are indeed reliable in terms of learning, considered the expected goals, and made us certain that the way we have approached the subject is consistent with a holistic education and that at the same time values the tiniest details, which are fundamental to all the learning-teaching process.

Nombrar lo que no tiene nombre : Una mirada sobre la monarquía en Metamorfosis de Ovidio

Nuestro propósito en este trabajo es analizar cómo la caracterización de los dos primeros reyes romanos, Rómulo y Numa (libros XIV y XV), y el episodio de Cipo (libro XV) en Metamorfosis de Ovidio dan forma literaria a una crisis de la experiencia: el fin de la República y el pasaje a una nueva forma de gobierno, el Imperio. Tomaremos como marco teórico el concepto de "estructura del sentir" de Raymond Williams

Between "uxor", "mater" and "concubina". Profile and identity of the Emperor Constantine in Late Roman legislation

We aspire to shape the Constantine’s personality in particular by analyzing his loving relationship, first with Minervina and then with Fausta, and not forgetting the bond with his mother Helena, hence the reference to uxor, mater and concubina in our title. We will analyze if these women exercised any influence on the composition of his production rules and, if so, to what extent they were able to determine the historical development of the following decades. From this point of view we must consider in general the emperor had to combine their political claims and government with these relationships, showing great skill in handling times and ways, always putting the first to the second.

Population and Government in Colonial Buenos Aires. An Approach to the Study of the Tensions Generated by Demographic Growth in the City (1740-1776)

The relationship between population and government in the City of Buenos Aires is analyzed, focusing on the tensions generated by the arrival of new individuals, a local elite with great interests in commerce and in charge of community affairs, and Spanish functionaries that progressively adopted the ideals of the Bourbon Dynasty, despite also being implicated in local logics. It interests us to observe the governors’ perspectives with respect to everyday developments in the city, their preoccupations and interests, and how they would vary the mechanisms to which they resorted in order to organize daily life, in the period defined between 1740 and 1776.

Estudo comparativo entre o código deontológico português de Medicina Dentária e o código de ética odontológico brasileiro

A Medicina Dentária é uma área da medicina em que os profissionais podem realizar procedimentos cirúrgicos invasivos e prescrever formulações farmacológicas de maneira autónoma, a partir de diagnósticos realizados por eles próprios. O exercício das atividades médicas deve ser pautado em princípios éticos, legais e na compreensão da realidade social, económica e cultural do local onde exercem os profissionais. Para tanto, o estudo dos Códigos Deontológicos e dos Códigos de Ética e Deontológicos são importantes instrumentos na busca por este paradigma de conduta. O Objetivo deste trabalho de pesquisa pretende comparar o Código Deontológico de Medicina Dentária em Portugal com o Código de Ética Odontológica Brasileiro, buscando diferenças e semelhanças. Realizou-se uma revisão bibliográfica do Código Deontológico Português e do Código de Ética Odontológica Brasileiro, utilizando-se dos próprios códigos, livros e artigos pertinentes ao estudo. Pode-se verificar que ambos os códigos são Completos. O Código Deontológico Português é complementado por Regulamentos internos da Ordem dos Médicos Dentistas. Existem temas específicos no Código Brasileiro que não estão presente no Código Português.

Synthesis and differential antiproliferative activity of Biginelli compounds against cancer cell lines: Monastrol, oxo-monastrol and oxygenated analogues

The synthesis and differential antiproliferative activity of monastrol (1a), oxo-monastrol (1b) and eight oxygenated derivatives 3a,b–6a,b on seven human cancer cell lines are described. For all evaluated cell lines, monastrol (1a) was shown to be more active than its oxo-analogue, except for HT-29 cell line, suggesting the importance of the sulfur atom for the antiproliferative activity. Monastrol (1a) and the thio-derivatives 3a, 4a and 6a displayed relevant antiproliferative properties with 3,4-methylenedioxy derivative 6a being approximately more than 30 times more potent than monastrol (1a) against colon cancer (HT-29) cell line.

A forma do privilégio: renda, acessibilidade e densidade em Natal-RN

The aim of this work is to understand the morphological expression of ground occupation by the higher income population, by focusing on population distribution in accordance with income layers and demographical density, as well as topological accessibility (HILLIER and HANSON, 1984) resulting from the urban grid structure. It endeavors to identify a functional organizing principle regarding the intra-urban space of Natal capital city of the state of Rio Grande do Norte, the research focus. In order to achieve this, census data as well as syntactic data were utilized for mapping and spatial analysis of income patterns, topological accessibility and demographical density using Geographical Information System GIS. The organizing principle was named as the Form of Privilege, a pattern that concentrates or tends to concentrate wealth, topological accessibility and low demographical density. Attempting to assess its extent, beyond Natal, this principle was applied to other Brazilian northeastern capitals such as: Fortaleza, CE; Teresina, PI; Aracaju, SE; Recife, PE; and João Pessoa, PB. Findings point out that although the urban structures of these cities are not immune to the Form of Privilege, Natal is emblematic of this phenomenon, a fact that demonstrates the perverse character of its spatial process, which historically creates privileged areas within the city, by means of the appropriation of accessibility as well as of the many urban benesses that are related to it by higher income groups at the expense of the major part of the population, which though being the people mostly in need of the benefits originating from the urban form are excluded from them

Evaluación in vitro de hongos nativos antagonistas de Moniliophthora rereri (Cif. & Par., Evans et al.,) en el cultivo de cacao (Theobroma cacao L.)

El cacao es afectado por una diversidad de microorganismos patógenos, entre ellos el hongo Moniliophthora roreri (Cif. & Par., Evans et al.,) causante de la moniliasis, que es una de las enfermedades de mayor importancia de este cultivo. El uso irracional de plaguicidas sintéticos para el manejo de esta enfermedad ha generado problemas al agroecosistema y la salud humana, por lo que se está demandando el uso de alternativas agroecológicas. En este contexto, el objetivo principal de esta investigación fue generar información acerca de la capacidad antagónica in vitro mostrada por hongos nativos contra la moniliasis del cacao. Se recolectaron muestras de suelo, hojas, corteza, frutos sanos y enfermos en tres zonas cacaoteras de Nicaragua para la caracterización morfológica del patógeno y de los potenciales microorganismos antagonistas. Las pruebas de antagonismo “in vitro” se realizaron a través de la técnica del cultivo dual. Se evaluó el crecimiento radial del patógeno y de los antagonistas, el porcentaje de inhibición del crecimiento radial (PICR) del patógeno y la capacidad de control biológico de los hongos antagonistas. Se probaron cuatro técnicas para la conservación de los hongos antagonistas. Se obtuvieron cuatro aislados del patógeno M. roreri y 17 aislados de hongos antagonistas. El PICR del patógeno ejercida por aislados del antagonista Trichoderma varió de 40.13% a 46.77%, en los aislados del antagonista Paecilomyces el PICR osciló entre 59.38% y 67.43%, en el único aislado del antagonista Clonostachys el PICR fue de 62.33%-67.22%. Los 17 aislados se ubicaron en las clases 1, 2 y 3 de la escala de valoración de antagonismo. La mejor técnica de conservación de hongos antagonistas y de M. roreri fue la de conservación con glicerol. Los resultados de este estudio indican que en el agroecosistema de cacao existen microorganismos nativos que tienen potencial para ser usados como agentes de control biológico del patógeno M. roreri.

An examination of the techniques used to capture mangrove crabs, Ucides cordatus, in the Mamanguape River estuary, Northeastern Brazil, with implications for management.

The present research, undertaken in a mangrove swamp in northeastern Brazil (Mamanguape River Estuary), examined the factors that led to the overwhelming acceptance of the tangle-netting technique by crab harvesters in detriment to the now illegal tamping technique. Both techniques are the only ones currently used at our study site and in many other areas in Brazil, despite being prohibited by law. Data were collected through direct observations to determine capture efficiency, productivity, daily production, selectivity, and harvesting effort, and through interviews with crab harvesters, focusing on their perceptions of the capture techniques, the conditions of crab stocks and the sales price of a dozen crabs. Our results indicated that the two capture techniques did not significantly differ in terms of their efficiency or productivity, but daily production rates differed significantly, being greater using tangle-netting. The tangle-netting permits a greater harvesting effort (6 hours and 34 min) compared to tamping (4 hours and 19 min). Tangle-netting is also less selective than tamping indicated by the larger number of captured smaller specimens, including females. This results in a lower average sales price for a dozen crabs caught by tangle-netting (US$ 0.95) compared to tamping (US$ 1.02). The greater daily production of crab harvesters using the tangle-netting technique nevertheless increased their net gain, explaining their preference for this method, Given that tangle-netting results in greater harvesting pressure but lower selectivity compared to tamping, it may potentially be less sustainable. All of the crab harvesters interviewed having more than 20 years of experience (n = 34) stated they perceived that stocks of U. cordatus had become reduced over the last 20 years, together with average crab sizes. It is now important to examine the structure of the local U. cordatus population and to assess its fishery to allow evaluating whether the illegal, but prominent tangle-netting and tamping mangrove crab capture techniques are sustainable or not. We further suggest improving the dialogue between decision makers and fishermen, which barely exists to date, to initiate a discussion about possible ways of resolving the current situation of illegality of the fishermen. This will be key to achieving effective sustainable co-management of this important natural mangrove forest resource.

Densidad mineral ósea, calcio dietético y factores presuntivos de riesgo de osteoporosis en mujeres ecuatorianas de la tercera edad

Justificación: La osteoporosis es causa de fracturas patológicas y pérdida de autonomía y validismo en la mujer post-menopáusica. La identificación de factores de riesgo puede servir en la prevención de la aparición de esta co-morbilidad. Objetivos: Determinar la asociación entre la desmineralización ósea y características demográficas, clínicas y antropométricas selectas de la mujer post-menopásica que puedan asumirse como factores de riesgo. Diseño del estudio: No experimental, transversal, analítico. Serie de estudio: 53 mujeres con edades ≥ 60 años atendidas en el Hospital "San Juan" de Especialidades de Riobamba (Provincia del Chimborazo, República del Ecuador). Material y método: Se determinó la densidad mineral ósea (DMO) en 2 regiones de interés (columna lumbar I fémur) mediante DEXA (DPX-L, Lunar Technologies, EEUU). La desmineralización ósea se estableció ante puntajes "t" < -1,0 desviaciones estándar. La cuantía y calidad de los ingresos de Calcio dietético se estimaron mediante el puntaje pCa que tiene en cuenta la frecuencia de consumo de alimentos tenidos como fuente de calcio y la biodisponibilidad del mineral. Se evaluaron la naturaleza y la fuerza de la asociación entre la desmineralización ósea, por un lado, y los factores presuntivos de riesgo de osteoporosis y el estado del ingreso del calcio dietético, por el otro. Resultados: La desmineralización ósea fue dependiente de la región de interés: Fémur: Osteoporosis: 13,2% + Osteopenia: 50,9%; Columna lumbar: Osteoporosis: 49,1% + Osteopenia: 37,7%. Los mayores ingresos de calcio dietético se concentraron en: Leche y lácteos (pCa = 26,56), Carnes, pescados, mariscos y huevos (pCa = 6,51), Frijoles y otras leguminosas (soja incluida) (pCa = 2,85); y Verduras (pCa = 2,54); respectivamente. El puntaje "t" de DMO se asoció con la edad de la mujer, los antecedentes familiares de fracturas óseas, el Índice de Masa Corporal (IMC), y la grasa corporal (estimada mediante DEXA). Los ingresos de calcio dietético fueron independientes de los factores presuntivos de riesgo de desmineralización ósea, y del puntaje "t" de DMO en las regiones de interés. Las razones de disparidades para las variables asociadas univariadamente con la DMO fueron como sigue: Edad: OR = 2,09 (p < 0,05); IMC: OR = 0,278 (p = 0,059): y Grasa corporal: OR = 0,553 (p > 0,05); respectivamente. Conclusiones: La desmineralización ósea se asocia significativamente con el envejecimiento femenino, y una mayor presencia de la grasa corporal. Los antecedentes familiares de fracturas óseas pueden servir para identificar a la mujer post-menopáusica con un riesgo incrementado de desmineralización ósea. Se deben emprender investigaciones ulteriores para establecer el papel del ejercicio físico y mejores ingresos de calcio dietético como factores protectores de la pérdida de la DMO.

QUALIDADE DE VIDA DE PROFESSORAS DO ENSINO BÁSICO DA REDE PÚBLICA

Objetivo: Avaliar os aspectos associados à qualidade de vida (QV) de professoras do ensino básico da rede pública de Viçosa-MG, buscando relações com a classe econômica. Métodos: Trata-se de um estudo descritivo transversal, desenvolvido entre março e outubro de 2013, realizado com 156 professoras da cidade de Viçosa-MG. Foram aplicados os questionários World Health Organization Quality of Life/BREF e o Critério de Classificação Econômica. Utilizou-se também um questionário contendo tempo de atuação e carga horária semanal de trabalho. Para comparação dos domínios da QV entre as classes econômicas, utilizou-se o teste ANOVA one way, com post hoc de Tukey. Para todos os tratamentos, adotou-se um nível de significância de p<0,05. Resultados: As avaliadas apresentaram idade média de 43,88 (+ 10,61) anos, carga horária de trabalho semanal de 29,00 (+ 10,35) horas e tempo de atuação profissional de 16,17 (+ 8,91) anos. A maioria das avaliadas se encontrava na classe econômica B1/B2, com 60,3%. O escore médio da QV geral foi de 68,43 (+ 11,69) pontos, com maiores valores para os domínios “relações sociais” e “físico”. Foi encontrada uma redução na média do domínio “meio ambiente” em relação à menor classe econômica (p=0,011). Houve correlação fraca e inversa entre o domínio “relações sociais” e a carga horária semanal de trabalho (r=-0,16; p=0,031). Conclusão: A QV da população estudada foi considerada entre regular e boa, levando-se em conta a escala do protocolo. Houve associação somente entre o domínio “meio ambiente” e a classe econômica.

Fatalism, Attributions of Failure and Academic Performance in Mapuche and Non-Mapuche Chilean Students

This study investigated the role of fatalism as a cultural value orientation and causal attributions for past failure in the academic performance of high school students in the Araucania Region of Chile. Three thousand three hundred and fourty eight Mapuche and Non-Mapuche students participated in the study. Consistent with the Culture and Behavior model that guided the research, the test of causal models based on the analysis of structural equations show that academic performance is in part a function of variations in the level of fatalism, directly as well as indirectly through its influence in the attribution processes and failure-related emotions. In general, the model representing the proposed structure of relations among fatalism, attributions, and emotions as determinants of academic performance fit the data for both Mapuche and non-Mapuche students. However, results show that some of the relations in the model are different for students from these two ethnic groups. Finally, according to the results from the analysis of causal models, family SES appear to be the most important determinant of fatalism.
