Encaminhamento óptimo do tráfego em redes Triple Play

A Internet é responsável pelo surgimento de um novo paradigma de televisão – IPTV (Televisão sobre IP). Este serviço distingue-se de outros modelos de televisão, pois permite aos utilizadores um elevado grau de interactividade, com um controlo personalizado sobre os conteúdos a que pretende assistir. Possibilita ainda a oferta de um número ilimitado de canais, bem como o acesso a conteúdos de Vídeo on Demand (VoD). O IPTV apresenta diversas funcionalidades suportadas por uma arquitectura complexa e uma rede convergente que serve de integração a serviços de voz, dados e vídeo. A tecnologia IPTV explora ao máximo as características da Internet, com a utilização de mecanismos de Qualidade de Serviço. Surge ainda como uma revolução dentro do panorama televisivo, abrindo portas a novos investimentos por parte das empresas de telecomunicações. A Internet também permite fazer chamadas telefónicas sobre a rede IP. Este serviço é denominado VoIP (Voz sobre IP) e encontra-se em funcionamento já há algum tempo. Desta forma surge a oportunidade de poder oferecer ao consumidor final, um serviço que inclua os serviços de Internet, de VoIP e de IPTV denominado serviço Triple Play. O serviço Triple Play veio obrigar a revisão de toda a rede de transporte de forma a preparar a mesma para suportar este serviço de uma forma eficiente (QoS), resiliente (recuperação de falhas) e optimizado (Engenharia de tráfego). Em redes de telecomunicações, tanto a quebra de uma ligação como a congestão nas redes pode interferir nos serviços oferecidos aos consumidores finais. Mecanismos de sobrevivência são aplicados de forma a garantir a continuidade do serviço mesmo na ocorrência de uma falha. O objectivo desta dissertação é propor uma solução de uma arquitectura de rede capaz de suportar o serviço Triple Play de uma forma eficiente, resiliente e optimizada através de um encaminhamento óptimo ou quase óptimo. No âmbito deste trabalho, é realizada a análise do impacto das estratégias de encaminhamento que garantem a eficiência, sobrevivência e optimização das redes IP existentes, bem como é determinado o número limite de clientes permitido numa situação de pico de uma dada rede. Neste trabalho foram abordados os conceitos de Serviços Triple Play, Redes de Acesso, Redes Núcleo, Qualidade de Serviço, MPLS (Multi-Protocolo Label Switching), Engenharia de Tráfego e Recuperação de falhas. As conclusões obtidas das simulações efectuadas através do simulador de rede NS-2.33 (Network Simulator versão 2.33) serviram para propor a solução da arquitectura de uma rede capaz de suportar o serviço Triple Play de uma forma eficiente, resiliente e optimizada.

Educação matemática crítica: a sua importância na formação de uma sociedade do futuro

Este trabalho foi elaborado no âmbito do Mestrado de Ensino de Matemática do 3º Ciclo do Ensino Básico e Secundário da Universidade da Madeira, no ano lectivo de 2010/2011. Tem como grandes objectivos apresentar, de forma sucinta, o trabalho desenvolvido pelo grupo de estágio ao longo do estágio pedagógico e analisar a importância da educação^matemática crítica na formação de cidadãos críticos e conscientes. Assim, no estudo realizado procuraremos compreender o modo como os alunos reagem e aplicam os seus conhecimentos matemáticos quando se encontram em contextos sociais. Neste trabalho alertamos para os perigos de uma sociedade cegamente obediente e abordaremos ainda de que forma a educação matemática crítica poderá desenvolver o sentido crítico dos alunos e exploraremos a importância da investigação na educação matemática. Para isso, incentivaremos os alunos a explorarem e analisarem vários anúncios publicitários e cartazes políticos e tirarem as suas conclusões acerca dessas informações, tomando desta forma uma decisão consciente em relação a essa informação.

O profissional da informaçao e as habilidades exigidas no mercado de trabalho emergente

Diante de um novo perfil do emprego e do mercado de trabalho - que se transforma marcadamente em face das tecnologias de informação e comunicação (TIC) há uma demanda por profissionais munidos de novas habilidades e competências. Assim, objetiva-se, de modo geral, analisar as novas habilidades demandadas pelo mercado de trabalho atual para o profissional da informação. Para tanto, busca-se especificamente, caracterizar os fatores determinantes do contexto atual; verificar o impacto das TIC no mercado de trabalho do profissional da informação; e conhecer as transformações ocorridas no perfil deste profissional frente a estas mudanças.

ANÁLISE COMPARATIVA DO CONHECIMENTO, ATITUDES E PRECONCEITOS DE UNIVERSITÁRIOS DOS CURSOS DE PEDAGOGIA, EDUCAÇÃO FÍSICA E MEDICINA EM RELAÇÃO À EPILEPSIA

Epilepsy is a chronic disorder of the central nervous system, most frequently characterized by abnormal electrical impulses in the brain. It is the oldest recorded neurological disease and has been surrounded by myths, mistaken beliefs and preconceptions. Three professionals work with epileptic patients on a daily basis: teachers, physical educators and physicians . This study aimed to analyze and compare the level of knowledge, preconceptions and attitudes of undergraduate students in the courses of Pedagogy, Physical Education and Medicine, future professionals who will deal with epileptic patients. This descriptive observational study was conducted with 286 university undergraduates of both sexes (women 99/34.6% and men 187/65.4%) from the first to fourth year of Pedagogy, Physical Education and Medicine courses at the Universidade Estadual Rio Grande do Norte (UERN), with mean age of 23 years. A validated and adapted 17-question questionnaire, divided into nine knowledge-based questions, five related to preconceptions and three on attitudes, was applied. Results allowed elaboration of a manuscript entitled Comparative Analysis of Knowledge, Attitude and Preconceptions in University Undergraduates of Pedagogy, Physical Education and Medicine Courses in Relation to Epilepsy. The findings of this article show that knowledge of epilepsy in the three groups is very satisfactory. The low level of preconception indicates that educational or clarifying information is being transmitted, albeit by television, a layman s information vehicle, which has undoubtedly contributed to reducing the stigma of epilepsy through educational information. Results also suggest a lack of knowledge on how to act during a seizure, especially in education professionals. Although there are limitations in our sample, the relevance and contribution of this study is to call attention to the importance and need for these future professionals to be informed and learn correct attitudes with respect to epilepsy during their academic formation. This is essential at a time when the disease is being brought out of the shadows. This research was supported by the Office of the Dean of Teaching, and Deans of Pedagogy, Physical Education and Medicine at UERN. The research was made possible by the multidisciplinary interaction among a physical educator, child neurologist and statistician, all contributing to achieving the aims set out here

Família e TV: mais que dominação e subordinação.

This work analises the social relationship between Television and the Family though the resignification of individuals about Television messages and the speeches that they make about Family. Firstly, the objective is to understand if the principles, values and beliefs constructed and communicated (repassed) inside the Family filter the messages from the Mass Media. Secondly, if there still exists a family culture able to forge identity against so many cultural exchanges. Thirdly, what the function of this identity in the production of senses is. In session 1 and 2, a general approach about the dissemination of Mass Media in Society and the pertinence of the work is presented. Session 3 is about the method used: a qualitative research, with thirteen families from Natal-RN, situated in the Middle Class. The theorical base is considered in the fourth session where the reference to the evolution of the Family is made, with enphasis on the Middle Class and some theories that analyze the pheomenom of the Mass Media , specially in the second half of twentieth century. In session 5 and 6, the research data is presented and analyzed. Finally, in the last session, as a conclusion it can be said that the value of the Family as emotional support is reforced by the speeches and practices that interfere in the signification procces, singular aspects, as well as the social repertoire constructed per si and by institutions (including the family) moreover, mediative message is assimilated by the receiver and becomes understood inside the learned speeches during the receiver‟s history of life, although these messsages are also components in the construction of these repertoire.

A dimensão simbólica e midiática da política e a história da dona de casa que virou guerreira : a construção da imagem pública de Wilma de Faria em 2002 e 2006

This paper examines two aspects. First, the symbolic dimension of politics and some of the elements that make up this universe, as the scenario, the representation, the myth, the spectacle, the media and the political and electoral marketing. We assume that the policy brings together a set of traits related to both reason and the human subjectivity, and can not be summed up in just a few calculations based on rationality. In the case of elections, in a process (ritual, according Irlys Barrier) of choice, there is a meeting of two systems of representations: to that transmitted by a political actor, in a scene from a particular context, based on a life trajectory unique, and the other from the public, crossed by social relations, situations own wishes, desires, expectations and unique perspectives. Between them there are the means of mass media (especially television), and with them the advent of language media and advertising applied to politics, changing the layout of public visibility and inaugurating what Rejane Accioly Carvalho will call the "aesthetics of mostrabilidade". This does not necessarily mean a preponderance of media on politics as a whole but only its adaptation to that with regard to contact with the public, the ad extra portion of the policy, according to Wilson Gomes. In a second aspect, try to apply these elements to a specific study to verify them in building an effective public image, in this case, the current governor of Rio Grande do Norte, Wilma de Faria. The concept of public image is from the book of Wilson Gomes The transformation was visible in the mass media, and relates to a conceptual image to fix "personality traits" through political history, personal conduct, action of image makers and the public reception. For this we will review some videos aired on Free Time for political propaganda in the years 2002 and 2006.

Visibilidade espetacular e relações de poder no reality show BB9

Dans le présent travail, nous faisons une incursion sur l'exposition de la réalité, dans une étude spécifique du programme Big Brother Brasil 9, approcher le sujet de la visibilité et de l'exposition à travers les concepts de la culture, corps, à et communication. Nous avons lié l'him/it à la théorie de pouvoir proposée par Michel Foucault. Le corps, dans notre analyse, est prisonnier à ordinateur individuel propulse, en camionnant des transformations dans le filet de rapports établis pour les participants de BBB. Nous avons cherché, à travers un plurimetodológica de l'approche, expliquer comme ils sentent les rapports de pouvoir dans ce televisivo du programme/jeu et la transformation des gens anonymes dans célébrités, raconter, avec tout ce avec la logique d'une consommation d'images. Dans l´époque contemporain, les images sont mediateurs puissants de la communication et ils servent de support au midiatique des produits, dans la fiction et banalité ou actions différentes et expériences du quotidien. Comme référence de recherche empirique, le travail est basé au Big Brother-9, a exposé par le Globe Net de Télévision, canal ouvert, dans la période du 13 janvier à avril 07, 2009. Avant que les résultats aient obtenu par l'analyse, nous avons vérifié ce BBB-9 à travers les plusieurs épreuves, les preuves et situations ont créé au-dedans parmi les participants du jeu il met à jour des rapports de pouvoir et d'exclusion, dans le différend pour le succès individuel, le tout coût. Le publique/telespectateur quand participe à travers le vote du programme travaille comme un régulateur pédagogique qu'il qualifie, Il classifique et il punit les conduites privées des joueurs, en étant responsable pour l'acceptation possible, ou pas, des gens, pendant s'écouler du jeu

Da política no vídeo à videopolítica: um estudo hermenêutico do programa Jornal do Dia (Natal/RN)

Esta investigación tiene como objetivo realizar un estudio sobre el noticiero "Jornal do Dia" de la TV Ponta Negra, afiliada a la cadena de televisión SBT con sede en Natal / Rio Grande do Norte. El estudio evalúa, desde una perspectiva crítica, el comportamiento de la sección política de ese noticiero sobre la cobertura que ha estado haciendo sobre los acontecimientos políticos en el estado. Específicamente, estamos interesados en conocer, a través del estudio detallado de sus noticias, como los "hechos políticos" del Estado, entendida como una práctica política que se informó, se presentan en su noticiero. Del punto de vista metodológico, la investigación se toma la decisión de utilizar la hermenéutica de profundidad (HP) como propuesto por Thompson (2007) en su libro "La ideología y la cultura moderna". Sugerimosla HP porque es una referencial de alta eficacia analítica para el estudio de los medios de comunicación y en particularde la ideología. De este modo, como se versade una investigación sobre las "formas simbólicas" creemos que estamos en posesión de una importante herramienta metodológica capaz de permitir la comprensión e interpretación de las noticias diariamente "teleplasmadas"

Rejeição e voto em eleição contemporânea: um estudo de caso da eleição à prefeitura do município de Natal/RN (2012)

Given the importance that political science and social sciences give studies of voting behavior, this study sought to fill this academic discussion another important element that makes up this complex set. From the campaign trail to City Christmas in 2012 work has been undertaken analysis of rejection in the first and second rounds of this election. For this analysis we used two sources of data: quantitative research, conducted by Search Consult the first and second rounds of elections, and the use of focus group technique, performed in the second round of elections. Knowing the various factors that may affect the voting decision, but also the dynamism that pervades a political dispute, seek, with this work, contribute to the deepening of the rejection of studies, aiming to bring subsidies presenting information to better explain the behavior studies election. The results showed that there is a less expressive, the chamda strong rejection. We speak of that rejection based on a political, historical and ideological. The reason for the weak presence of strong rejection seems to be little involvement of voters with politics and, consequently, low knowledge about politics and politicians. We observe, however, evidence of rejection volatile. We refer here to a kind of rejection that develops during the election process depending on the preference of the voter and according to the circumstances of the campaign. The data also lead us to conclude that television is as an instrument for the dissemination of ideas that can contribute in shaping the opinion of viewers. The role of political parties in representing the interests of the people have lost their strength in recent years. The data also show that, to the extent that increases the preference of voters in the electoral process, also increases its rejection
