Análise das matrizes curriculares dos cursos de Comunicação Social com habilitação em Jornalismo no Brasil: um retrato da realidade nacional

O artigo em questão é fruto de pesquisa sobre a educação jornalística e teve como objeto as matrizes curriculares de todos os cursos de Comunicação Social com habilitação em jornalismo do Brasil. O objetivo foi o de fazer um diagnóstico das estruturas curriculares do referido curso em todas as regiões do país e depois consolidar um desenho da estrutura nacional. Utilizamos como metodologia a pesquisa quantitativa e qualitativa. Nossas principais constatações foram em primeiro lugar a de que o espaço destinado aos conteúdos de Síntese/Comunicação na estrutura curricular de todas as regiões é mínimo, o que dificulta a inter-relação entre a teoria e a prática. em segundo lugar pudemos verificar que, apesar das premissas previstas nas DCN para o curso de Comunicação Social, as realidades regionais não estão contempladas nas matrizes curriculares dos cursos.

Devaneio do olhar: uma experiência de produção e leitura da imagem através do vídeo na prática pedagógica

A partir de la constatación de la importancia que la imagen viene ejerciendo en la sociedad actual y, más específicamente, en el proceso educativo, el presente estudio busca dilucidar algunas cuestiones referentes a la lectura de la imagen, producción de imágenes y su utilización en el proceso de enseñanza y aprendizaje. Para tanto, buscó relacionar los elementos que constituyen la narrativa visual a la perspectiva de Paulo Freire, de buscar en el contexto de vida la producción de conocimiento aliándolos las tecnologías de la imagen visando la alfabetización visual y también al acceso democrático a las nuevas tecnologías de comunicación e información. El estudio fue mediado por la elaboración de un documental en vídeo, en que enfocamos las imágenes fijas del artista local Newton Navarro, con fines de experiencia en producción y lectura de la imagen. La realización del trabajo y la aplicación en aula los colocaron delante de una nueva perspectiva educativa: el cambio de la posición de espectadores para la de productores. Eso posibilitó un nuevo mirar, donde la lectura de la imagen permitió una mayor reflexión acerca de las actuales prácticas educativas

Gêneros do discurso e escrita: o que as coleções didáticas de português (des)prestigiam no ensino da produção textual?

Through the examination of official indicators, it can be observed that writing is pointed out as one of the main problems concerning formal basic education. However, this teaching-learning object is one of the central objectives at school, having an essential role in different curricular components as well as in the interaction demands required by society. Such paradox indicates, therefore, the relevance of investigations which analyze the intrinsic elements of child development as written text producer. Hence, the main purpose of this research consists of analyzing the treatment given to the types of discourse and the teaching situations in which the written text are produced, concerning Portuguese language didactic material collections approved by Programa Nacional do Livro Didático (PNLD 2010) the Brazilian program of didactic book and worked at elementary school. Such materials correspond to the collections adopted in municipal education system schools from Natal, RN which were below the official education indicator IDEB 2009. Thus, the questions that guide this work are: 1. During writing production lessons, is the diversity of types of discourse effectively worked on didactic collections? 2. Which are the types of discourse and the social spheres prioritized when teaching writing production? 3. How is the situation addressed in the production of the written text should be produced? For this research, we retook the authors Bakhtin, Bunzen, Faraco, Freire, Rodrigues, Rojo, Schneuwly e Dolz and we made a list of all types of discourse and spheres contemplated in the propositions of the writing production in didactical books, concerning the eight collections which compounds the first moment of analysis. Then, we verified how the situation of production is oriented by examining two didactic collections if and how they express the elements referring to the social-historical, functional and linguistic-discursive context of the text to be produced. The data obtained indicate: lack of diversification of types of discourse in the collection that compounds the Aggregate Sample of the research; the conception of a diversity based on the didactic of visiting; the recognition of all canonical and hegemonic types of text as one of the privileged objects of study; the centralization on the standard variety of the language and the devaluation of the representative types of cultural diversity; the shortage of productions which retrace to written language related to different technologies of communication and information; and the little emphasis on the types of discourse related to public language practices. As for the situations of production, it is observed the predominance of the school as a producer of dialogic relationships, whose propositions present, for example, text addressees, enunciative positions, support and contexts of restricted circulation, especially at school. Two divergent situations are observed among the collections: the lack of a work in which the situation of production is under the perspective of the types of discourse as object of teaching-learning; the concept of the types of discourse as object of reflection, presenting a differentiated didactic orientation towards the situation of production. This research contributes, therefore, with a mapping of the existence and the treatment of the types of discourse on propositions of writing production in didactic books; with the critical analysis of the approach of written activities, considering the elements of the historical-social, functional and linguistic-discursive context; thus, through teaching, research and public policies, use and selection of didactic material for the area

Desenvolvimento de um ressoador retangular de fenda com múltiplas camadas de substrato e com utilização de material PBG para sistema de comunicação sem fio

In the globalized world modern telecommunications have assumed key role within the company, causing a large increase in demand for the wireless technology of communication, which has been happening in recent years have greatly increased the number of applications using this technology. Due to this demand, new materials are developed to enable new control mechanisms and propagation of electromagnetic waves. The research to develop new technologies for wireless communication presents a multidisciplinary study that covers from the new geometries for passive antennas, active up to the development of materials for devices that improve the performance at the frequency range of operation. Recently, planar antennas have attracted interest due to their characteristics and advantages when compared with other types of antennas. In the area of mobile communications the need for antennas of this type has become increasingly used, due to intensive development, which needs to operate in multifrequency antennas and broadband. The microstrip antennas have narrow bandwidth due to the dielectric losses generated by irradiation. Another limitation is the degradation of the radiation pattern due to the generation of surface waves in the substrate. Some techniques have been developed to minimize this limitation of bandwidth, such as the study of type materials PBG - Photonic Band Gap, to form the dielectric material. This work has as main objective the development project of a slot resonator with multiple layers and use the type PBG substrate, which carried out the optimization from the numerical analysis and then designed the device initially proposed for the band electromagnetic spectrum between 3-9 GHz, which basically includes the band S to X. Was used as the dielectric material RT/Duroid 5870 and RT/Duroid 6010.LM where both are laminated ceramic-filled PTFE dielectric constants 2.33 and 10.2, respectively. Through an experimental investigation was conducted an analysis of the simulated versus measured by observing the behavior of the radiation characteristics from the height variation of the dielectric multilayer substrates. We also used the LTT method resonators structures rectangular slot with multiple layers of material photonic PBG in order to obtain the resonance frequency and the entire theory involving the electromagnetic parameters of the structure under consideration. xviii The analysis developed in this work was performed using the method LTT - Transverse Transmission Line, in the field of Fourier transform that uses a component propagating in the y direction (transverse to the real direction of propagation z), thus treating the general equations of the fields electric and magnetic and function. The PBG theory is applied to obtain the relative permittivity of the polarizations for the sep photonic composite substrates material. The results are obtained with the commercial software Ansoft HFSS, used for accurate analysis of the electromagnetic behavior of the planar device under study through the Finite Element Method (FEM). Numerical computational results are presented in graphical form in two and three dimensions, playing in the parameters of return loss, frequency of radiation and radiation diagram, radiation efficiency and surface current for the device under study, and have as substrates, photonic materials and had been simulated in an appropriate computational tool. With respect to the planar device design study are presented in the simulated and measured results that show good agreement with measurements made. These results are mainly in the identification of resonance modes and determining the characteristics of the designed device, such as resonant frequency, return loss and radiation pattern

Por uma pedagogia do oprimido midiático: meios de comunicação e suas intervenções na escola

En este trabajo nos ocupamos de la convergencia de la fotografía, el vídeo y la música, intermediado por una estación de radio en la escuela, instalada en la escuela Municipal de Djalma Maranhão, Natal, Rio Grande do Norte, en una clase de 5º año de jóvenes y adultos en el año escolar 2007. Se analizan las intervenciones causados los que participan en la vida escolar, a partir de las actividades realizadas por ellos, en la producción de programas de radio. Los procedimientos metodológicos sobre la base de la etnometodologia (COULON, 1995a, 1995b), en la investigación cualitativa (BOGDAN, BIKLEN, 1999, DENZIN y LINCOLN, 2006), participante como observador (MAY, 2004) y la investigación-acción (THIOLLENT, 1992). La comprensión de Paulo Freire en la comunicación e la educación es nuestro principal referente teórico. Los experimentos citados en los medios de comunicación revelaron varias posibilidades de mejora en la enseñanza y el aprendizaje, como el aumento de la autoestima de los estudiantes, social y de inclusión educativa de personas con discapacidad, disminución de la timidez y facilitar la comunicación entre los sujetos, lo que permite el diálogo entre ellos, intervino en sus relaciones sociales, más allá de los límites de la escuela. La investigación confirma, entonces, que la comunicación y la educación son parte de la misma naturaleza

Explicações de crianças internadas sobre a causa das doenças: implicações para a comunicação profissional de saúde-paciente

Esta pesquisa pretendeu estudar o desenvolvimento cognitivo e as explicações sobre a causalidade das doenças em crianças hospitalizadas, particularmente a influência nas explicações da experiência com doenças e da escolaridade. Participaram da pesquisa cinqûenta crianças brasileiras internadas em um hospital público, com diferentes diagnósticos e idade variando entre cinco e nove anos. O desenvolvimento cognitivo e as concepções sobre as causas das doenças foram avaliados dentro de um referencial piagetiano. Como em estudos anteriores, as crianças processaram as informações numa seqüência cognitiva previsível. Entretanto, as crianças internadas mostraram atraso na aquisição da conservação, e explicações com poucos elementos subjetivos, sem referências à própria doença. As causas atribuídas às doenças foram similares às apontadas por crianças de outros países. Foi estatisticamente significativa a relação entre a complexidade das explicações e o número de internações. A maioria da amostra, independente da idade e nível cognitivo, atribuiu o adoecimento à desobediência, possível mecanismo adaptativo ao desamparo, resultado que parece trazer implicações a serem consideradas quando se abordam pacientes infantis.
