TELEVISÃO REGIONAL E REDE NACIONAL:UM ESTUDO DE CASO DE EMISSORAS AFILIADAS DA REDE BANDEIRANTES DE TV

A aceleração do processo de globalização da mídia em todo o mundo trouxe como contrapartida um crescente interesse pela mídia regional. Para se examinar esse processo no Brasil, buscou-se analisar como a programação regional de cinco emissoras regionais afiliadas a uma rede nacional de televisão e localizadas no Norte, Nordeste, Centro-Oeste, Sudeste e Sul se articula com a programação nacional. A Rede Bandeirantes de Televisão foi escolhida por estar presente em todo o país e atingir um grande número de domicílios. O método utilizado é o qualitativo, de caráter descritivo e optou-se pelo estudo de caso múltiplo, com o objetivo de se obter uma perspectiva comparada da programação das emissoras regionais estudadas. A principal conclusão é que, apesar da pequena produção regional, com ênfase na informação (telejornal e entrevista) pode-se constatar, em algumas regiões, o interesse da audiência por programas voltados para a cultura regional.(AU)

A TV DIGITAL DIVULGADA NO BOLETIM ELETRÔNICO DO FNDC: UM ESTUDO SOBRE O COMPORTAMENTO DA MÍDIA NA IMPLANTAÇÃO DA TV DIGITAL NO BRASIL

Implantada no Brasil na década de 50, a TV a mídia de maior abrangência e poder ideológico entre seus públicos encara sua segunda grande transformação: ela deixa de ser analógica e passa a ser digital. Com isso, traz à tona novas possibilidades de recepção e a possível convergência de meios. Nesse contexto, o objetivo deste estudo foi analisar o processo de instalação do Sistema Brasileiro de Televisão Digital Terrestre (SBTVD-t) a partir do clipping on-line do Fórum Nacional pela Democratização da Comunicação (FNDC). A análise desse material teve como foco averiguar se o FNDC foi tendencioso ou não na veiculação de matérias voltadas aos aspectos técnicos da nova tecnologia, em detrimento de seu potencial social. Para tanto, optou-se por uma pesquisa de base quantitativa em que as informações e os dados coletados levaram à constatação de que o FNDC se mostra pouco eficaz como aparato crítico-apreciativo da grande mídia, além de não cumprir alguns de seus objetivos ao reproduzir discursos e ideologias de outros veículos. Da mesma forma, verificou-se ainda que o Governo Federal também fugiu aos objetivos listados nos decretos presidenciais que instituem e dispõem sobre a implantação do SBTVD.(AU)

A presente pesquisa propõe analisar o contexto educacional ocorrido no período da ditadura militar, buscando extrair aspectos históricos e educacionais referentes ao período (1964- 1985). Trata-se de uma pesquisa realizada com professores do antigo segundo grau da rede pública de ensino do Município de Santo André (S.P). Optou-se por entrevistar seis professores que atuaram durante esse contexto histórico. Para investigar, foi utilizada a abordagem histórica-metodológica de cunho qualitativo, elegendo a memória como fonte principal de estudo. Para tanto, recorreu-se às contribuições de Bosi (Memória e sociedade: lembranças de velhos, 1984), Thompson (A voz do Passado, 1992), Romanelli (História da Educação no Brasil, 1978), Freitag (Escola Estado e Sociedade, 1980), Góes (O golpe na Educação, 1996), Cunha (Educação e Desenvolvimento Social no Brasil, 1977), Cardoso (Para uma crítica do presente, 2001), Vieira (Estado e miséria social no Brasil, 1995), Minguili (Direção de Escola de 2º grau no Estado de São Paulo, 1984), Arelaro (A extensão do ensino básico no Brasil, 1988), Teixeira (Política e administração de pessoal docente, 1988), Hilsdorf (História da educação brasileira, 2005), Gadotti (Educação e poder, 2001), Germano (Estado militar e educação no Brasil, 1990), Saviani (Escola e democracia, 1986), Santos (Professoras em tempos de mudanças, 2003). A hipótese trabalhada centra-se em interpretar a postura dos professores que atuaram no período em questão, relativa ao regime político que se instalou no País durante esta época, e de que forma isso repercutiu no seu trabalho docente. Na análise do contexto político/social e educacional, recorreu-se à revisão que forneceram subsídios para compreender e explicitar a voz do professor.

Desenvolvimento de emulsões o/a contendo extrato glicólico de açai e avaliação da atividade fotoprotetora

Sunscreen use is the most common photoprotection alternative used by the population, and so these products should offer improved protection with broad - spectrum, UVA and UVB protection . Vegetal substances have recently been considered as resources for sunscreen formulations due to their UV spectrum absorption and antioxidant properties. The Euterpe oleracea Mart., popularly known as açai, in its che mical composition contain polyphenols compounds, such as anthocyanins and flavonoids , to which antioxidant properties have been attributed . The aim of this work was to develop O/W sunscreens emulsions con taining açai glycolic extract ( AGE) and to evaluate both their physical stability , safety and photoprotective efficacy. The safety of the extract was evaluated by in vitro phototoxicity and cytotoxicity tests. Emulsions containing AGE and sunscreens were formulated using different types and concentrations o f polymeric surfactant (Acrylates/C 10 - 30 Alkyl Acrylate Crosspolymer and Sodium Polyacrylate). The influence of two rheology modifiers (Polyacrylamide (and) C13 - 14/Isoparaffin (and) Laureth - 7 and Carbomer) on the stability was also investigated. Physical stability was evaluated by preliminary and accelerated studies. The macroscopic analyses, pH value and electrical conductivity determinations and rheological behavior were evaluated at different time intervals . The in vivo Sun Protect Factor ( SPF ) was determined according to the International Sun Protection Factor Test Method – 2006 and UVA Protection Factor (FPUVA), wavelength critical and reason SPF/FPUVA were performed according to the method Colipa 2011. The extract did not present cytotoxic ity and phototoxic ity . The stable emulsion containing 5% glycolic extract of açai and 1.0% of sodium poliyacrylate showed pseudoplastic and thixotropic behavior . The sunscreen emulsion containing açai glycolic extract showed a SPF 25.3 and PF - UVA = 14.97. Whe n açai glycolic extract was added in the emulsion sunscreen, no significant increase in the in vivo SPF and FPUVA values were observed. This emulsion showed 1.69 of the SPF/PF - UVA ratio and a critical wavelength value of 378 nm, so may therefore be conside red a sunscreen with UVA and UVB protection.

Desenvolvimento teórico e experimental de FSS com elementos fractais de Gosper em estruturas de multicamadas

The fractal self-similarity property is studied to develop frequency selective surfaces (FSS) with several rejection bands. Particularly, Gosper fractal curves are used to define the shapes of the FSS elements. Due to the difficulty of making the FSS element details, the analysis is developed for elements with up to three fractal levels. The simulation was carried out using Ansoft Designer software. For results validation, several FSS prototypes with fractal elements were fabricated. In the fabrication process, fractals elements were designed using computer aided design (CAD) tools. The prototypes were measured using a network analyzer (N3250A model, Agilent Technologies). Matlab software was used to generate compare measured and simulated results. The use of fractal elements in the FSS structures showed that the use of high fractal levels can reduce the size of the elements, at the same time as decreases the bandwidth. We also investigated the effect produced by cascading FSS structures. The considered cascaded structures are composed of two FSSs separated by a dielectric layer, which distance is varied to determine the effect produced on the bandwidth of the coupled geometry. Particularly, two FSS structures were coupled through dielectric layers of air and fiberglass. For comparison of results, we designed, fabricated and measured several prototypes of FSS on isolated and coupled structures. Agreement was observed between simulated and measured results. It was also observed that the use of cascaded FSS structures increases the FSSs bandwidths and, in particular cases, the number of resonant frequencies, in the considered frequency range. In future works, we will investigate the effects of using different types of fractal elements, in isolated, multilayer and coupled FSS structures for applications on planar filters, high-gain microstrip antennas and microwave absorbers

Consumo c(l)iente: abordagem do gênero anúncio publicitário em livros didáticos de língua portuguesa do ensino médio

Portuguese language textbooks, according to what has been preconized on the official document to education, have been configured on discursive genres imported from diverse spheres of human activity. Adverts, genre of ample social circulation, spread from the Advertising sphere to the schools and started being approached by these collectaneas as an object and a tool for teaching. Therefore, this research deals with the approach of ads in Portugese textbooks. These discursive practices matter for the impact or appeal they exert over the (new) consumers, among which High School students; for their representation in the capitalist system, which guides us on our relationships and social practices; and for the mix of languages that end up at their composition, once they encapsulate the spirit of our time, par excellence, the one from the verbal-visual genres. To understand the treatment given to these advertising pieces, from questions/commentaries related to them, two collections were selected by the Programa Nacional do Livro Didático – Textbook National Program (PNLD 2012) among the ones more used by public High Schools in Natal/RN. From Applied Linguistics, from mestizo, nomadic and inter/transdisciplinary identity (MOITA LOPES, 2009), this study falls within the discursive chain of the interpretive tradition of historical-cultural approach (FREITAS, 2010) and names the Bakhtin Circle and its language‟s dialogical conception as inescapable partners. The data of the colletaneas show that the genre approach can happen as concrete utterance, as linguistic artifact and as hybrid, at work with questions and without questions, with the predominance of its occurrence in the portion of the volume devoted to the study of grammar. In the literature chapters and production/interpretation of compositions, it insert is incipient or it doesn‟t happen in the volume. Such a provision has implications for multiliteracies (ROJO, 2012) of the citizen student, once the lack or the abundance of critical reading proposals for this genre, that demand from the student the exercise of knowledge that is necessary to the construction of linguistic and social meanings, can be responsible for guide to a more conscious consumerism (material and cultural) by the chief customers of the work under review. The approaches of the genres seems to indicate a gradual transition that such material have undergone, which means, from the focus on clauses to the focus on utterances, or even the approach as linguistic artifact to hybrid and the concrete utterance, in search of overcoming the traditional tendency of taking advantage of formal aspects of the language, to the detriment of enunciative ones, and for coming into harmony with the guidelines and parameters of teaching in contemporary times, bringing the school duties close to the rights in life.

Papel do município e relações federativas: atuação de municípios cearenses nas políticas de formação continuada de alfabetizadores

The investigation analyze s the role of the municipalities in the ongoing development of literacy teachers, having as a field of study the municipalities of Jaguaruana and Palhano, both in the State of Ceará. The political - educational space adopted as a sample of the study is the p eriod between the years 2003 and 2006, when the emphasis on cooperative action among the federated entities is observed in the Government’s guidelines and Brazilian educational policies, showing the municipal presence in the implementation and execution of these policies. T he historical - dialectical materialistic perspective, understood as an analysis of the social reality as historical elaboration and product of the human praxis, is expressed as the required theoretical - methodological path. The investigatio n is operationalized through interconnected stages: one that involves bibliographical and documental analysis, in which the theoretical input of the research is added, as well as the Federal, State and M unicipal documents accessed ; and another, regarding t he field work, studying the specific character of the object and its mutual rela tionships in the municipalities . The research brings the notion of intergovernmental relationships and cooperative mechanisms as central theoretical tools and, dialoguing with them, ideas such as decentralization, municipalization and municipal autonomy are inserted into a theoretical/practical body, through which the historical and logical aspects of the object are detailed. The study describes and interprets the policies of on going development of literacy teachers with focus on the national guidelines formulated since the 1990’s and on the govern mental incorporation in the national and subnational spaces. In this sense, the analysis is based on the comprehension of the interrel ationship between the municipal policies and the p olicies created by the S tate or Federal G overnments in order to offer ongoing development of literacy teachers. Considering the investigated sample, it shows how the municipal role and the relationships bet ween the State and municipalities of Ceará have emerged, as well as their characteristics regarding the education management policies, taking into account the practices of municipalization and cooperation between the State and municipalities in their histo rical composition. It shows the practices which aim at the ongoing development of literacy teachers observed in the researched municipalities, pointing out the realities and specific marks left by municipal presence in the area, demonstrating the assigned role and the role played. Based on the points of view of the managers interviewed in the municipalities of Jaguaruana e Palhano, it is possible to note the meaning and effectiveness of the policies carried out. With such elements, it discusses the municipa l asymmetries in their homogeneities and heterogeneities rega rding the execution of their federative role. The analysis shows that th e role of the municipalities vary according to the historical, political and social interventions in each municipality. In the fields of formulation and execution of educational policies, the actions of the municipal governments, situated and with expressive interferences, reveal asymmetries in the sense that some municipalities have bigger autonomy and participate more effect ively in the production and distribution of policies than others. In terms of the researched realities, the study shows that taking care of the policies of ongoing development of literacy teachers is not a task that should be assigned exclusively to the mu nicipalities, nonetheless it is a role that they play with varying degrees of success. This role is in fact a joint competence of the federated entities, in the scope the Brazilian cooperative federalism.

Cloud Stratus: uma plataforma de middleware para desenvolvimento de aplicações em nuvem

Cloud Computing is a paradigm that enables the access, in a simple and pervasive way, through the network, to shared and configurable computing resources. Such resources can be offered on demand to users in a pay-per-use model. With the advance of this paradigm, a single service offered by a cloud platform might not be enough to meet all the requirements of clients. Ergo, it is needed to compose services provided by different cloud platforms. However, current cloud platforms are not implemented using common standards, each one has its own APIs and development tools, which is a barrier for composing different services. In this context, the Cloud Integrator, a service-oriented middleware platform, provides an environment to facilitate the development and execution of multi-cloud applications. The applications are compositions of services, from different cloud platforms and, represented by abstract workflows. However, Cloud Integrator has some limitations, such as: (i) applications are locally executed; (ii) users cannot specify the application in terms of its inputs and outputs, and; (iii) experienced users cannot directly determine the concrete Web services that will perform the workflow. In order to deal with such limitations, this work proposes Cloud Stratus, a middleware platform that extends Cloud Integrator and offers different ways to specify an application: as an abstract workflow or a complete/partial execution flow. The platform enables the application deployment in cloud virtual machines, so that several users can access it through the Internet. It also supports the access and management of virtual machines in different cloud platforms and provides services monitoring mechanisms and assessment of QoS parameters. Cloud Stratus was validated through a case study that consists of an application that uses different services provided by different cloud platforms. Cloud Stratus was also evaluated through computing experiments that analyze the performance of its processes.

Desenvolvimento de estruturas integradas de filtros e antenas para aplicações em sistemas de comunicações sem fio

This paper presents a study of the integration of filters and microstrip antennas, yielding devices named as filtennas for applications in wireless communications systems. The design of these structures is given from the observation of filtennas based integration between horn antennas and frequency selective surfaces (FSS), used in the band X. The choice of microstrip line structures for the development of a new configuration filtennas justifies the wide application of these transmission lines, in recent decades, always resulting in the production of circuit structures with planar light-weight, compact size, low cost, easy to construct and particularly easy to integrate with other microwave circuits. In addition, the antenna structure considered for the composition of filtennas consists of a planar monopole microstrip to microstrip filters integrated in the feed line of the antenna. In particular, are considered elliptical monopole microstrip (operating in UWB UWB) microstrip filters and (in structures with associated sections in series and / or coupled). In addition, the monopole microstrip has a proper bandwidth and omnidirectional radiation pattern, such that its integration with microstrip filters results in decreased bandwidth, but with slight changes in the radiation pattern. The methods used in the analysis of monopoles, and filters were filtennas finite elements and moments by using commercial software Ansoft Designer and HFSS Ansoft, respectively. Specifically, we analyze the main characteristics of filtennas, such as radiation pattern, gain and bandwidth. Were designed, constructed and measures, several structures filtennas, for validation of the simulated results. Were also used computational tools (CAD) in the process of building prototypes of planar monopoles, filters and filtennas. The prototypes were constructed on substrates of glass-fiber (FR4). Measurements were performed at the Laboratory for Telecommunications UFRN. Comparisons were made between simulated and measured, and found good agreement in the cases considered

Análise da dinâmica deposicional das praias de Cacimbinha e do Madeiro, Tibau do Sul-RN, Brasil

The Cacimbinha and Madeiro beaches are located in the eastern coast of Rio Grande do Norte state, in the municipality of Tibau do Sul. Given the indicative of erosion in the coast of this district and the coastal processes acting on the beaches, the global aim of this project is comprehend the evolution of depositional environment on the Cacimbinha beach, moreover, the project seeks to characterize deposits from the Cacimbinha and Madeiro beaches, according to the geomorphologic compartments identified on these beaches; distinguish the coastal features which possibly interact with the Cacimbinha beach; identify the potential relationship between the sediments from the coastal features and the deposits from Cacimbinha beach; understand which depositional processes that prevail at each facies deposited on the beach; and identify the probable sedimentary environments and its energy of deposition through of the materials recorded on the Cacimbinha beach. This study was based on previous bibliographic and field research, both guided by academic works, laws, concepts and theories concerning the physical geography, geomorphology of the quaternary, sedimentary geology and stratigraphy. Thus, the methodology was divided in three steps: Prefield step: office work was performed; Field step: Sampling of facies of sedimentation; PosField step: analysis and integration of data obtained during the research period. Thus, the results showed deposicional facies with distinguished energy in the relief compartments, beach and terrace. After the sedimentary analysis and its interpretation linked to the architecture of the mounted sections based on drilling, it became possible to trace the evolutionary history of this stretch of beach. Therefore, it can be stated that studies performed on coastal areas are of great importance, as long as, around the world, the most part of urban zones are seated on deposits of quaternary age and, then this work improve the knowledge regarding the sedimentary dynamics of this beach, becoming scientific support for management and planning of this area which focus on, mainly, the foreign tourism

Desenvolvimento de novos biolubrificantes hidráulicos derivados dos óleos de maracujá e de moringa in natura e epoxidados

With the increasing environmental awareness, maximizing biodegradability and minimizing ecotoxicity is the main driving force for new technological developments. Thus, can be developed new biodegradable lubricants for use in environmentally sensitive areas. The aim of this study was to obtain new bio-lubricants from passion fruit (Passiflora edulis Sims f. flavicarpa Degener) and moringa (Moringa oleifera Lamarck) epoxidized oils and develop a new additive package using experimental design for their use as a hydraulic fluid. In the first stage of this work was performed the optimization of the epoxidation process of the oils using fractional experimental design 24-1 , varying the temperature, reaction time, ratio of formic acid and hydrogen peroxide. In the second step was investigated the selectivity, thermodynamics and kinetics of the reaction for obtaining the two epoxides at 30, 50 and 70 °C. The result of the experimental design confirmed that the epoxidation of passion fruit oil requires 2 hours of reaction, 50 °C and a ratio H2O2/C=C/HCOOH (1:1:1). For moringa oil were required 2 hours reaction, 50 °C and a ratio of H2O2/C=C/HCOOH (1:1:1.5). The results of the final conversions were equal to 83.09% (± 0.3) for passion fruit oil epoxide and 91.02 (±0,4) for moringa oil epoxide. Following was made the 23 factorial design to evaluate which are the best concentrations of corrosion inhibitor and anti-wear (IC), antioxidant (BHA) and extreme pressure (EP) additives. The bio-lubricants obtained in this step were characterized according to DIN 51524 (Part 2 HLP) and DIN 51517 (Part 3 CLP) standards. The epoxidation process of the oils was able to improve the oxidative stability and reduce the total acid number, when compared to the in natura oils. Moreover, the epoxidized oils best solubilized additives, resulting in increased performance as a lubricant. In terms of physicochemical performance, the best lubricant fluid was the epoxidized moringa oil with additives (EMO-ADI), followed by the epoxidized passion fruit oil with additives (EPF-ADI) and, finally, the passion fruit in natura oil without additives (PFO). Lastly, was made the investigation of the tribological behavior under conditions of boundary lubrication for these lubricants. The tribological performance of the developed lubricants was analyzed on a HFRR equipment (High Frequency Reciprocating Rig) and the coefficient of friction, which occurs during the contact and the formation of the lubricating film, was measured. The wear was evaluated through optical microscopy and scanning electron microscopy (SEM). The results showed that the addition of extreme pressure (EP) and anti-wear and corrosion inhibitor (CI) additives significantly improve the tribological properties of the fluids. In all assays, was formed a lubricating film that is responsible for reducing the coefficient of metal-to-metal wear. It was observed that the addition of EP and IC additives in the in natura vegetable oils of passion fruit and moringa did not favor a significant reduction in wear. The bio-lubricants developed from passion fruit and moringa oils modified via epoxidation presented satisfactory tribological properties and shown to be potential lubricants for replacement of commercial mineral-based fluids.

Caracterização morfológica-sedimentar do vale inciso Apodi-Mossoró e plataforma continental adjacente - Bacia Potiguar Offshore

Systems of incised valleys have been studied in different continental shelves, including the Brazilian continental margin. The interest to characterize this feature is given by the information that it can provide variations on sea level, as well as the ability to host economically significant quantities of hydrocarbons in reservoirs located in deposits filling of the incised valleys. This thesis has the overall objective to characterize the morphology and sedimentary cover of the incised valley Apodi-Mossoró, located in the Northern Continental shelf of Rio Grande do Norte state, adjacent to Areia Branca city. The methodology included the integration of satellite imagery, bathymetric data, sedimentological data, shallow seismic, and the identification of foraminifera. The results indicate that the ApodiMossró incised valley is currently formed by two channels, shallow channel and deep channel, which have distinct morphological and sedimentological characteristics. The deep channel has connection with one of the heads of the Apodi Canyon, located in the slope area. The acquisition, processing and interpretation of shallow seismic data allowed the recognition of the depositional surface, erosional surface, discordance, and sismofaceis. The erosional surface mapped from shallow seismic sections is possibly a indicative of an ancient surface of valley incision, where it would probably be associated with the limit Pleistocene/Holocene. Different sismofaceis were identified and reflect the rise in sea level with standards sometimes agradacional, sometimes progradational. The thickness of sediments on this surface was estimated at a maximum of 22m thick in the central portion of the incised valley. Statistically, there are differences between the adjacent continental shelf and channels, and between these channels, for the content of calcium carbonate, organic matter, sand and mud perceptual, except for the gravel grain size. The analysis of living and dead foraminifera showed the presence of fifty species distributed in regards to morphology, depth and type of sediment. Four type of seismic echocharacteres were identified and mapped, as well as their bedforms, indicating different sedimentary processes along the incised valley. The integration of results suggests an activation of the Apodi-Mossoró incised valley in the Late Pleistocene.
