Esta dissertação apresenta um estudo exploratório sobre a experiência de implantação de um sistema digital de segurança. O estudo teve como locus a Guarda Civil Metropolitana de São Paulo e o objetivo geral da pesquisa é analisar o uso das tecnologias da informação e comunicação no campo operacional da organização. Primeiramente foi realizada a pesquisa bibliográfica para rastreamento de temas análogos. Foi possível verificar a escassez de estudos sobre as tecnologias da informação e comunicação na Segurança Pública no Brasil. Dos raros trabalhos encontrados o que deu inspiração para essa pesquisa foi o experimento realizado em Brasília, na área de Gestão do Conhecimento e da Tecnologia da Informação, que investigou a integração de sistemas de info rmações na Segurança Pública do Distrito Federal. Para a realização deste estudo de caso adotou-se a metodologia qualitativa com pesquisas bibliográfica, documental e de campo (entrevistas e observações diretas). Os resultados obtidos demonstram a necessidade de investimentos em tecnologias da informação e comunicação, objetivando a integração e a interoperabilidade das organizações de Segurança Pública. Os resultados também confirmaram os achados em pesquisas e estudos sobre a violência urbana que apontam que só os investimentos na estrutura técnica, em pessoal, em gestão de segurança, chamada política de combate à violência e à criminalidade, não resolve. É preciso urgência na gestão de políticas públicas integradas para combater as causas provocativas da violência e da criminalidade que são a miséria crescente, o desemprego, a falta de serviços públicos eficientes, em especial no setor da saúde e da educação e a ausência de políticas sociais, todos entendidos como violência.(AU)

O trabalho apresenta um estudo de caso do site Wikileaks, fundado pelo ex-hacker australiano Julian Assange, que ganhou fama mundial em 2010 por vazar documentos secretos dos Estados Unidos relacionados às guerras do Afeganistão e Iraque, e das embaixadas americanas de todo o mundo. A publicação de todo este conteúdo gerou uma grande controvérsia no alto escalão da política internacional e trouxe a tona como os donos do poder e da mídia monopolizada agem para calar os discursos de narradores que podem colocar a sobrevivência política destes atores do poder em risco. Este trabalho, portanto, apresenta um caso onde as novas mídias digitais promoveram aquele que foi chamado de o maior vazamento da história e como os atores políticos reagiram a este fenômeno, com uma campanha de pressão e difamação de Assange para tentar cessar as ações do site.

No presente trabalho investigou-se a adoção por parte das instituições educacionais dos recursos e ferramentas disponíveis nas mídias digitais sociais, que permitem a comunicação síncrona e assíncrona, estimula a comunicação para maior interatividade, dialogicidade e colaboração entre os atores envolvidos no processo ensino-aprendizagem da educação a distância. Para tanto, verificou-se como os alunos que estudam na EAD reagem às novas possibilidades oferecidas com o advento das novas tecnologias da informação e comunicação - NTICs. O estudo focou os alunos que estavam, no momento da pesquisa, cursando os segundos bimestres dos Cursos de Tecnólogos em: Marketing, Logística, Recursos Humanos e Gestão Comercial em EAD, das universidades Anhanguera e Metodista, dos pólos de São Caetano do Sul e Mauá. Na seleção da amostra, optou-se pelo modelo não probabilístico do tipo intencional, adotando-se o critério de que os alunos selecionados conheciam os recursos e as ferramentas utilizadas nas mídias digitais sociais das instituições. Como instrumento de medida, utilizou-se um questionário tipo Likert composto por 7 dimensões e 32 assertivas, além da técnica de entrevista de grupo focal, totalizando 5 encontros. Resgatou-se historicamente alguns pontos sobre o movimento das novas tecnologias, sobretudo as digitais, bem como a educação na modalidade a distância, desde o século passado até a atualidade. Além disso, procurou-se entender o quanto as ações governamentais têm apoiado as transformações tecnológicas que impactam direta e indiretamente nos aspectos educacionais. Outro tema abordado para a discussão desse trabalho foi a Sociedade do Conhecimento, que tem papel de suma importância para o desenvolvimento e avanço das Novas Tecnologias da Comunicação e Informação. As discussões para as análises dos resultados foram norteadas pela Teoria da Ação Comunicativa de Habermas que ajudou a compreender e indicar a importância dos conceitos vistos sobre o mundo da Vida e o mundo do Sistema, dentro da realidade atual da EAD e das NTCs. Os dados apontaram que os alunos que estudam nessas duas Universidades são em sua maioria, casados, possuidores de filhos e pretendem com seus estudos dar um salto qualitativo em suas carreiras, acessam a internet de suas residências, local de trabalho e nas universidades que estudam. São conhecedores e aproveitam as Mídias Digitais Sociais - MDS oferecidas por suas universidades e as utilizam para se comunicarem com seus colegas e seus professores, mas, interagem melhor com as ferramentas oferecidas pelo mercado, que estão disponíveis na Internet e fazem uso de forma bastante significativa do mensageiro e-mail para a comunicação entre seus colegas. A pesquisa também assinalou que, o público pesquisado pertencente à geração de imigrantes digitais se adapta e utiliza relativamente bem as ferramentas oferecidas por ambas as Universidades. Entretanto, também indicou que, os recursos e as ferramentas digitais oferecidas pela instituição de ensino que podem facilitar o processo comunicacional dentro das instituições educacionais são conhecidos, mas, ainda se encontram aquém, frente às possibilidades oferecidas pelas novas tecnologias digitais utilizadas no mercado. Para a maioria, as MDS são de grande importância e facilitam o processo comunicacional dentro da relação de ensino-aprendizagem, entretanto, apontam que o diálogo poderia ser mais dinâmico se houvesse por parte dos professores ou tutores EAD maior interação on-line. A pesquisa assinalou que as mídias digitais sociais e suas ferramentas, oferecidas pelo mercado e que são utilizadas fora da rede do EAD, por serem mais interativas e intuitivas e estarem vinculadas a um ambiente mais descontraído, permitem maior colaboração e uma comunicação muito mais ágil do que as vivenciadas na rede EAD.

A discussão sobre a formação de Professores sempre foi um desafio, especialmente em se tratando dos caminhos e descaminhos acerca das práticas cotidianas e, muito mais, ainda hoje, com a inserção da tecnologia dentro das salas de aula. A pesquisa investigou se o uso da tecnologia favorece a interação professor-aluno e se isso se torna um facilitador na busca de novos conhecimentos, colaborando para a alteração da prática cotidiana. Para desenvolver tais discussões realizamos uma revisão da literatura e da legislação sobre a formação de professores no contexto brasileiro e sobre a formação de professores e as tecnologias. Elaboramos análises das ações do Governo Federal, privilegiando o contexto do Estado de São Paulo por ser o foco da nossa investigação. Para a realização da pesquisa de campo contamos com a colaboração de professores do Ensino Fundamental II e do Ensino Médio de Escolas Estaduais e os responsáveis das Oficinas Pedagógicas das Diretorias de Ensino dos Municípios de Santo André e Mauá para a aplicação de um questionário e realização de entrevistas de aprofundamento. Verificamos que os esforços de implantação de projetos desenvolvidos pela rede estadual esbarram na burocracia e na descontinuidade, provocadas pela mudança de administração, onde se priorizam os interesses pessoais em detrimento dos interesses coletivos. Em contrapartida, encontramos os formadores nas Diretorias de Ensino, que precisam atender todas as questões administrativas e políticas, e, ao mesmo tempo, darem conta da formação continuada dos professores, resolvendo problemas que, muitas vezes, estão longe de suas possibilidades e verificamos também que o uso da tecnologia na atividade docente ainda não é o esperado, ou seja, estes professores não fazem uso pedagógico do computador, porém, o uso aumentou sistematicamente, mas trazê-lo para a sala de aula ainda é um desafio e reflete a forma de agir e de pensar dos professores envolvidos no processo desta pesquisa.

O século XXI trouxe profundas modificações na organização das sociedades e consequentemente no mundo do trabalho no âmbito da educação. O crescimento exponencial da dinâmica da comunicação nas sociedades possibilita a multiplicação generalizada de visões de mundo, a tecnologia é um agente de mudança e as inovações tecnológicas podem resultar em uma revolucionária quebra de paradigma educacional. Diante dos impasses de um mundo globalizado, em constante mutação cultural, surgem novas possibilidades de mediações que geram diferentes perspectivas para os processos educativos com a introdução das Tecnologias de Informação e Comunicação (TICs) e da Educação a Distância (EaD). Por esta razão, a Formação Docente é pesquisada tendo como objetivo analisar os impactos e as contribuições que as tecnologias trazem para este campo, especialmente no curso de Pedagogia, considerando uma experiência em EaD e sua relação com o curso na modalidade presencial a partir dos pressupostos norteadores do Projeto Pedagógico Institucional (PPI) na instituição pesquisada. Foi relevante perceber no decorrer da pesquisa bibliográfica e do estudo de campo que as duas modalidades apóiam-se na concepção de educação que está subjacente e que orienta as escolhas teórico-metodológicas adotadas pela instituição no seu PPI. A educação a distância possibilita a construção de um ambiente de aprendizagem mediado pelas TICs e novas compreensões sobre o processo de ensinar e aprender. O estudo mostra que a formação docente nesta modalidade deve estar articulada com o processo educativo e ter como eixo a concepção de um sujeito capaz de estabelecer novas formas de expressão e conhecimentos para trabalhar em uma educação do futuro. Portanto, é necessário pensar na Intencionalidade de sua formação, de modo a capacitá-lo com visão pedagógica crítica e objetivando que seja capaz de intervir no desenvolvimento educacional como um intelectual transformador.(AU)

In this work the degradation of real and synthetic wastewater was studied using electrochemical processes such as oxidation via hydroxyl radicals, mediated oxidation via active chlorine and electrocoagulation. The real effluent used was collected in the decanter tank of the Federal University of Rio Grande do Norte (ETE-UFRN) of Effluent Treatment Plant and the other a textile effluent dye Ácido Blue 113 (AB 113) was synthesized in the laboratory. In the electrochemical process, the effects of anode material, current density, the presence and concentration of chloride as well as the active chlorine species on site generated were evaluated. Electrodes of different compositions, Ti/Pt, Ti/Ru0,3Ti0,7O2, BDD, Pb/PbO2 and Ti/TiO2-nanotubes/PbO2 were used as anodes. These electrodes were subjected to electroanalytical analysis with the goal of checking how happen the anodic and cathodic processes across the concentrations of NaCl and supporting electrolyte used. The potential of oxygen evolution reaction were also checked. The effect of active chlorine species formed under the process efficiency was evaluated by removing the organic matter in the effluent-ETE UFRN. The wastewater treatment ETE-UFRN using Ti/Pt, DDB and Ti/Ru0,3Ti0,7O2 electrodes was evaluated, obtaining good performances. The electrochemical degradation of effluent-UFRN was able to promote the reduction of the concentration of TOC and COD in all tested anodes. However, Ti/Ru0,3Ti0,7O2 showed a considerable degradation due to active chlorine species generated on site. The results obtained from the electrochemical process in the presence of chloride were more satisfactory than those obtained in the absence. The addition of 0.021 M NaCl resulted in a faster removal of organic matter. Secondly, was prepared and characterized the electrode Ti/TiO2-nanotubes/PbO2 according to what the literature reports, however their preparation was to disk (10 cm diameter) with surface area and higher than that described by the same authors, aiming at application to textile effluent AB 113 dye. SEM images were taken to observe the growth of TiO2 nanotubes and confirm the electrodeposition of PbO2. Atomic Force Microscope was also used to confirm the formation of these nanotubes. Furthermore, was tested and found a high electrochemical stability of the electrode Ti/TiO2-nanotubes/PbO2 for applications such as long-term indicating a good electrocatalytic material. The electrochemical oxidation of AB 113 using Ti/Pt, Pb/PbO2 and Ti/TiO2-nanotubes/PbO2 and Al/Al (electrocoagulation) was also studied. However, the best color removal and COD decay were obtained when Ti/TiO2-nanotubes/PbO2 was used as the anode, removing up to 98% of color and 92,5% of COD decay. Analysis of GC/MS were performed in order to identify possible intermediates formed in the degradation of AB 113.

This dissertation deals with the constitutional limits on the exercise of patent rights and its effects on the oil, natural gas and biofuels. Held with the support of ANP / PETROBRAS, It seeks to show how the law will limit the exercise of industrial property, based on a reinterpretation of private law by the constitutional development perspective . Today it is a fact that Petrobras, a Brazilian joint venture, has the latest technology in various sectors of the oil industry, and is one of the highest investments in developing new technologies. The overall objective of this thesis is to establish the relationship between the public interest of the Petroleum Industry, Natural Gas and Biofuels and constitutional limits to the free exercise of patent rights, then confirm or refute our hypothesis that Article 71 on Industrial Property Law is contrary to the existing objectives in Article 3 of the Constitution of the Federative Republic of Brazil. The research aims to examine the relevant aspects of the legal nature attributed to IPGN constitutionally confronting the constitutional limits on the free exercise of patent rights, with the purpose to outline the state of the performance limits in the regulation of the economy, in particular the application of feasibility limitations on the right of property in favor of national interest on the strategic energy industry. The aim is to confront the fundamental rights to property and economic development, against the public interest, limiting these first. As to the objectives, the research will be theoretical and descriptive and harvest of industrial property, respect the possible impact of regulatory standards and limiting the right of ownership in the oil industry. To establish how the state will mitigate the intellectual property right, we discuss, at first, a definition of public interest from the general theory of state and sovereign character in order to establish a new concept of national interest and popular interest, which will in turn the definition of our concept of public interest. In the second phase, will be addressed the issue of industrial property rights and how to will be free exercise thereof, in the constitutional sphere, infra, and demonstrating the use of industrial property rights with examples of market and IPGN . After situating the industrial property rights in the constitution and national legislation, establish their relationship with the national and regional development, will be addressed in this chapter in particular the patent law, as most usual form of intellectual property protection in IPGN. Used a study highlighting the number of patents in the area of the analyzed industry, demonstrating with hard data the importance of a sector for industrial development. The relationship between the social function of intellectual property and the constitutional objective of development was characterized to demonstrate the strategic nature of oil to Brazil in the national and international scene, and put into question the hypothesis of the research which provides that even with large investments the lack of legal certainty in the sector turns out not to have a considerable volume of investment as it could.

The coastline from Rio Grande do Norte state is characterized for the presence of dunes and cliffs. The latter consist of slopes with height up to 40 meters and inclinations ranging from 30° to 90° wich horizontal. Thus, this dissertation had as objective the evaluation of the stability of cliff from Ponta do Pirambu in Tibau do Sul/RN, and the realization of a parametric study on the stability of a homogeneous cliff considering as variables the material's cohesion, the cliff height and the slope inclination. The study in Ponta do Pirambu considered yet the possibility of the existence of a colluvial cover with thickness ranging from 0.50 to 5.00 meters. The analyzes were performed by Bishop method, using GEO5 software. In parametric analysis were produced graphics that relate height cliff with the inclination, to safety factors equals to 1.00 and 1.50; besides graphics where it is possible easily get the lowest safety factor as from the cohesion, cliff height and its inclination. It was concluded that these graphs are very useful to preliminary analyzes, for the definition of critical areas in risk mappings in areas of cliffs and for determination of an equation for obtaining the lowest safety factor function of the strength parameters and of slope geometry. Regarding the cliff from Ponta do Pirambu, the results showed that the cliff is subject to superficial landslides located in the points where may there be the presence of colluvium with thicknesses greater than two meters. However, the cliff remains stable presenting the global safety factor equal or superior to 2.50 in the saturated condition.

This dissertation addresses issues considered essential for sustainable development of urban waterfronts and beaches. Many of these spaces, even though they are of public authorities, economic market and general population interests - due to its landscape, its importance for recreation purposes and as a basis of " Sun and beach Tourism " (Turismo de Sol e Praia), among other factors - have shown aesthetic, health and cultural degradation, entailing environmental, economic and social losses and conflicts. Based on this perception, the research aims to understand the main reasons for these negative results for beach spaces. To this end, it was chosen the case study of a typical urban beach, Ponta Negra Beach, located in Natal, RN. Ponta Negra is associated with the "postcard" of the city and it has been deserving of municipal urban planning legislation that legally recognizes the importance of its landscape. Also it has received constant investments by the Government through urban projects, arguing to leave the site attractive to its users. Nevertheless, in the last fifteen years, the beach has lived with the expansion of its problems, such as those related to bathing water, to coastal erosion, and to the mangling of its natural surroundings. Social conflicts have also been frequent in this time frame: conflicts between residents of the waterfront and traders who work on the beach, between the traders themselves, between the managers of space and fishermen, between managers and formal and informal traders. Many of these social and environmental conflicts have taken such grand proportions that became legal matters. Assuming that the problems identified are related to the issue of rationality - understood as a system of values, norms and actions that relate means and ends - and upholding the need for focused research on "environmental rationality" to understand and interpret the dynamics of social and environmental problems encountered on site, the research that guides the study relies on the Mexican economist Enrique Leff's theory on "environmental rationality" which, briefly, can be defined as a system of values, norms, actions and means and ends relations based on the principles of environmental management and sustainable development. Among other aspects, rationality encompasses cross-sectional planning of public administration, the participation of society in the management of environmental resources, interdisciplinary reorganization of knowledge, the clash of opposing interests and the conciliation of common goals of different social actors. The study evaluates the relationship between "environmental rationality", as proposed by Enrique Leff, with the management, urban interventions and uses observed in Ponta Negra Beach. For that, some benchmarks were established and considered in the research as related to sustainable development of the "beachy" atmosphere. Analytical instruments chosen were the urban transformations and the environmental and social problems that have been the target of lawsuits. Also part of the study, the problems that were the subject of civil investigations, which are investigation procedures carried out by the Prosecutor's Office.

This paper intends to analyze which contribution for teachers formative training the participation on extension projects can bring to the bachelors in Mathematics teaching. The research was conducted during the developing of a Project from the Program of Extension - Programa de Extensão UFU/Comunidade (PEIC) in a municipal school located in a country zone from Uberlândia-MG. The research was constituted by a series of activities with students from the ninth year of the Fundamental Education, Middle School. The main focus is the work developed by two bachelors of Mathemactics teaching from the Federal University from Uberlândia who were part of the PEIC team. This present research intends to answer the following question: How the extension project “Information technology and communication on Mathematics problem resolution in country zone schools” has contribited to reinforce and to (re)criate the fomative experiences of students from the Mathematics teaching course who have developed such project? The presente study is from a qualitative nature and has made use of the partaker searching methodology. The presente paper was organized in three chapters. On chapter I evidence is given to theoretical discussion made, having as main references the works of Larrosa, Ponte e Shön. Chapter II brings the description of the three activities that were developed and aplied during the PEIC Project, which are: Problems in the Park, Inaccessible Hight and Lili Game. On chapter III, the data analysis is presented. The data was obtained through instruments of registration such as: camera recording, photografic material, meetings reports, field notes, surveys and semi-structured interviews. The initial hypothesis aim is on the fact that the participation on extention projects during the graduation course can bring rich contribution for the teachers to be, since it’s going to provide the knowledge and chalenge close to the one from the future profession. With the analysis of the obtained results from the colected data, it was possible to conclude that the PEIC has provided the bachelors in Mathematics teching the opportunity of recreate and potenciate their formative experiences. Such opportunity happened in situations that involved, for example, planning makings, development of colective work, softwares usage, different school spaces and the direct interaction with school bureaucracy. Beyond that, it was possible to work with the cocepts of reflection in action in a way to contribute to the professional development of the future Mathematics teachers. Thereby, in our final considerations, is possible to conclude that extension projects performed during the graduation course can bring great contributions to the professional formation of the bachelors in Mathematics teaching, among them we highlight the potentiation of the previous formative experiences and the development of colective work and behavior related to a reflexive teacher.
