Considerando que os arquivos em emissora de televisão possuem diferentes configurações de registro da informação e que são significativos os estudos para área da Ciência da Informação e da Arquivologia, verificou-se os processo informacionais relacionados aos documentos existentes na emissora de televisão da Rede Globo. Cada suporte apresenta possibilidade de uma diversidade de formatos, estruturas e acessos a partir de suas características e pode-se entender o contexto vinculado a estes arquivos como uma nova possibilidade de mercado de atuação profissional e campo científico em construção. Para tanto, procedeu-se à pesquisa de abordagem qualitativa do tipo descritiva utilizando o método de pesquisa documental e de estudo de caso. O universo de pesquisa foi ao acervo da Rede Globo de Televisão em São Paulo por se tratar de seu rico apoio às pesquisas acadêmicas e do vasto acervo audiovisual de documentos custodiados. Desse modo, observou-se mediante a visita técnica ao acervo que os documentos em suportes diferentes ao papel utilizados como documentos possuem amplo uso nos produtos oferecidos pela instituição, o que permite concluir que auxiliam no desenvolvimento, na promoção e na construção da memória organizacional da emissora. / With the wide production of documents exceeding the paper in archival context, new conceptual dimensions that can understand the information without being confined to the formats, forms or supports have been discussed. Considering that the documents have different configurations of information registration and that they lack studies in the area of information science and archivology, the objective is to verify the contribution of non-conventional documents to the production of new activities of a television station. Each support presents a diversity of formats, structures and availability from its characteristics and one can understand the context linked to these archives as a new possibility of market and scientific field in construction. To do so, we proceed to the qualitative approach of descriptive and exploratory type with case study method and content analysis. The universe of research was due to the influence of Rede Globo television in support of academic research and the rich creative collection of documents in custody. In this way, it is observed that documents in different media such as clothes, dishes, coins and iconographic documents used have wide use in the products offered by the institution, which allows to conclude that they assist in the development, promotion and construction of the organizational memory of the broadcaster.

Les villes africaines croissent en population d’au moins 5% l’an et dépassent fréquemment 7% l’an. Or, lorsqu’une ville croît au taux de 7% annuellement, elle double sa population tous les dix ans. Cela signifie qu’il faudrait doubler la capacité des infrastructures et des équipements. Les pays en développement n’ont pas la capacité financière pour y faire face. D’où, entre autres problèmes, ceux de la dégradation des équipements, de l’environnement et des quartiers précaires. Comment planifier de telles agglomérations ? L’analyse des villes d’Abidjan, Lomé, Ouagadougou à travers leurs documents de planification, nous renseigne sur les pratiques utilisées. La ville de Bangui sert de cas d’étude approfondi à notre démarche. Planifier, c’est articuler les enjeux stratégiques à l’agir local Il faut donc relier les documents d’urbanisme et les documents complémentaires (schéma de drainage, commercial, de transport…). / Cities in Africa often grow in population develop at the rate of 5% yearly and sometimes go beyond 7%. When a city grows at the rate of 7% per year, its population doubles every ten years. This means that the capacities of infrastructures and equipments should be doubled. But developing countries do not have the financial capacities to stand it. As a result, there are many problems among which the degradation of equipments, the environment and precarious areas. How to plan such cities? After a study of large cities such as Abidjan, Lomé, Ouagadougou and their planning documents methods used, Bangui is chosen as the main site of the research. To plan is to articulate strategic stakes to local practices. This involves to link planning documents to other sectoral documents (for sewage, retail trade, transports…).

Nous abordons le problème de la synchronisation automatique d'un contenu audiovisuel avec une procédure textuelle qui le décrit. La stratégie consiste à extraire des informations sur la structure des deux contenus puis à les mettre en correspondance. Nous proposons deux outils d'analyse vidéo qui extraient respectivement : * les limites des évènements d'intérêt à l'aide d'une méthode de quantification de type dictionnaire * les segments dans lesquels une action se répète en exploitant une méthode d'analyse fréquentielle : le YIN. Ensuite, nous proposons un système de synchronisation qui fusionne les informations fournies par ces outils pour établir des associations entre les instructions textuelles et les segments vidéo correspondants. Une "Matrice de confiance" est construite et exploitée de manière récursive pour établir ces associations en regard de leur fiabilité. / We address the problem of automatic synchronization of an audiovisual content with a procedural text that describes it. The strategy consists in extracting pieces of information about the structure from both contents, and in matching them depending on their types. We propose two video analysis tools that respectively extract: * Limits of events of interest using an approach inspired by dictionary quantization. * Segments that enclose a repeated action based on the YIN frequency analysis method. We then propose a synchronization system that merges results coming from these tools in order to establish links between textual instructions and the corresponding video segments. To do so, a "Confidence Matrix" is built and recursively processed in order to identify these links in respect with their reliability.

Este trabalho buscou analisar as possíveis articulações da abordagem de temas em torno da saúde no ensino de Biologia no Ensino Médio, contextualizando essa abordagem desde os documentos oficiais da educação até as práticas educativas que acontecem em uma escola pública, referentes a esse componente curricular. De natureza quali-quantitativa, esta pesquisa adotou a metodologia do tipo de estudo de caso, tendo como partícipes uma escola central de um município da fronteira oeste do Rio Grande do Sul e professores de Biologia que nela atuam. O método de análise utilizado nos materiais coletados foi a análise de conteúdo. Dos documentos oficiais analisados, um deles apresentou elementos suficientes que o identificasse como um importante documento que visa dar suporte pedagógico aos professores, trazendo possibilidades e exemplos, de fácil compreensão, em como trabalhar os assuntos relacionados à saúde no componente curricular de Biologia, e envolvendo outras áreas do conhecimento. Quanto às concepções e às recomendações a respeito da abordagem de temas alusivos à saúde, constatou-se que os aspectos biológicos e socioambientais, para as questões que envolvem à saúde, estão articulados em consonância nos documentos oficiais, nos documentos escolares e para a área das Ciências da Natureza (CN), bem como no ensino de Biologia. Isso demonstra a importância e a necessidade de se discutir os aspectos sociais para a construção do conhecimento com os estudantes, além dos biológicos, bem como a ampliação da percepção sobre saúde e os seus determinantes. Outro fato importante na pesquisa foi que a maior parte das concepções analisadas nos registros dos documentos oficias da educação e dos documentos escolares estudados estão pautados, prioritariamente, na promoção da Literacia em saúde. Além disso, percebeu-se a existência de distintas concepções de saúde nos diferentes materiais de estudo, embora cada uma ressaltou as suas teorias e epistemologias, todas assinalam caraterísticas e elementos essenciais para entender e perceber a importância da abordagem de temas relativos à saúde dentro do contexto escolar. Também, notou-se que a escola estudada é vista como um espaço importante para estimular discussões em torno da saúde, associando o ensino de Biologia como uma área essencial para trabalhar os diversos assuntos relacionados à saúde em sala de aula com os estudantes. Espera-se que os conhecimentos atuais e mais relevantes em relação à saúde, traçados na escola e trabalhados no ensino de Biologia, sejam contemplados e considerados, com mais ênfase, na elaboração dos documentos oficiais estudados, bem como as diversas problemáticas que cercam as práticas de vida dos estudantes, os quais carecem de maiores esclarecimentos e orientações a respeito da abordagem de temas relacionados à saúde no contexto do Ensino Médio. / This study aims to analyse possible articulations of health themes approach in Biology teaching on High School, contextualizing this approach since official education documents until educational practices that happens at a public school, in relation this curriculum component.

The analyse method used in materials collected are content analysis. One of official documents analysed presents sufficient elements that identifies it as an important document that aim to give pedagogical support to teacher, bringing possibilities and examples of easy understanding in how to work issues relational to health in Biology, and involving others knowledge areas. About conceptions, recommendations regarding of health issue approach, we verify that socio-environmental, and biologic aspects has articulated in consonance on official documents, scholar documents and to Science Nature (SN) area, as well in Biology teaching. This demonstrate the importance and necessity of argue the social aspect for as knowledge construction with students, besides biological, as too enlargement of perception about health and its determinants. Other research important fact was that main part of conceptions analysed in education official and scholar documents registers, it primarily based in health literacy promotion. Beside this, we perceive existence of different health conceptions in the study materials, although each one evidence its theories and epistemologies, all of it appoints characteristics and elements essentials for understanding and perceiving the importance of health issue approach in of scholar context. In addition, we notes researched school it has seen as unique space for encouraging argue around of health, associating Biology teaching as one essential area for working several health themes in classroom with students. It will expected that current and more relevant health knowledge, traced on school and in Biology teaching, it might be contemplate and considered in the studied official documents elaboration with more emphasis, as well the different issues around students’ lifestyle, which needs major clarifications and orientations about health issue approach in High School context.

Active Documents is a technique for automating the handling and control of documents by making them a combination of service providers (mobile agents) and resources (compound documents) in the form of autonomous agents. The main focus of this solution is to provide an encapsulation of documents, including their data structures and related functionality, but also to enable documents to reflect upon themselves in respect of their computational environment, and take actions accordingly.

L'un des principaux problèmes que les applications Webs doivent gérer aujourd'hui est l'évolutivité des données. Dans cette thèse, nous considérons ce problème et plus précisément l'évolution des documents actifs. Les documents actifs sont documents XML pouvant évolués grâce à l'activation d'appel de services Web. Ce formalisme a déjà été utilisé dans le cadre de la gestion d'information distribuée. Les principales contributions de cette thèse sont l'étude théorique de différentes notions pour l'implémentation de deux systèmes gérant des applications manipulant des flux de données et des applications de type workflow. Dans un premier temps, nous étudions des notions reliées à la maintenance de vues sur des documents actifs. Ces notions sont utilisées dans l'implémentation d'un processeur de flux de données appelé Axlog widget manipulant des flux à travers un document actif. La deuxième contribution porte sur l'expressivité de différents formalismes pour contraindre le séquencement des activations d'un document actif. Cette étude a été motivée par l'implémentation d'un système gérant des workflows focalisés sur les données utilisant les documents actifs, appelé Axart. / One of the major issues faced by Web applications is the management of evolving of data. In this thesis, we consider this problem and in particular the evolution of active documents. Active documents is a formalism describing the evolution of XML documents by activating Web services calls included in the document. It has already been used in the context of the management of distributed data \cite{axml}. The main contributions of this thesis are theoretical studies motivated by two systems for managing respectively stream applications and workflow applications. In a first contribution, we study the problem of view maintenance over active documents. The results served as the basis for an implementation of stream processors based on active documents called Axlog widgets. In a second one, we see active documents as the core of data centric workflows and consider various ways of expressing constraints on the evolution of documents. The implementation, called Axart, validated the approach of a data centric workflow system based on active documents. The hidden Web (also known as deep or invisible Web), that is, the partof the Web not directly accessible through hyperlinks, but through HTMLforms or Web services, is of great value, but difficult to exploit. Wediscuss a process for the fully automatic discovery, syntacticand semantic analysis, and querying of hidden-Web services. We proposefirst a general architecture that relies on a semi-structured warehouseof imprecise (probabilistic) content. We provide a detailed complexityanalysis of the underlying probabilistic tree model. We describe how wecan use a combination of heuristics and probing to understand thestructure of an HTML form. We present an original use of a supervisedmachine-learning method, namely conditional random fields,in an unsupervised manner, on an automatic, imperfect, andimprecise, annotation based on domain knowledge, in order to extractrelevant information from HTML result pages. So as to obtainsemantic relations between inputs and outputs of a hidden-Web service, weinvestigate the complexity of deriving a schema mapping between databaseinstances, solely relying on the presence of constants in the twoinstances. We finally describe a model for the semantic representationand intensional indexing of hidden-Web sources, and discuss how toprocess a user's high-level query using such descriptions.

La Reconnaissance Optique de Caractères (OCR) est un processus qui convertit les images textuelles en documents textes éditables. De nos jours, ces systèmes sont largement utilisés dans les applications de dématérialisation tels que le tri de courriers, la gestion de factures, etc. Dans ce cadre, l'objectif de cette thèse est de proposer un système OCR qui assure un meilleur compromis entre le taux de reconnaissance et la vitesse de traitement ce qui permet de faire une dématérialisation de documents fiable et temps réel. Pour assurer sa reconnaissance, le texte est d'abord extrait à partir de l'arrière-plan. Ensuite, il est segmenté en caractères disjoints qui seront décrits ultérieurement en se basant sur leurs caractéristiques structurelles. Finalement, les caractères sont reconnus suite à la mise en correspondance de leurs descripteurs avec ceux d'une base prédéfinie. L'extraction du texte, reste difficile dans les documents hétérogènes scannés avec un arrière-plan complexe et bruité où le texte risque d'être confondu avec un fond texturé/varié en couleurs ou distordu à cause du bruit de la numérisation. D'autre part, la description des caractères, extraits et segmentés, se montre souvent complexe (calcul de transformations géométriques, utilisation d'un grand nombre de caractéristiques) ou peu discriminante si les caractéristiques des caractères choisies sont sensibles à la variation de l'échelle, de la fonte, de style, etc. Pour ceci, nous adaptons la binarisation au type de documents hétérogènes scannés. Nous assurons également une description hautement discriminante entre les caractères se basant sur l'étude de la structure des caractères selon leurs projections horizontale et verticale dans l'espace. Pour assurer un traitement temps réel, nous parallélisons les algorithmes développés sur la plateforme du processeur graphique (GPU). Nos principales contributions dans notre système OCR proposé sont comme suit :Une nouvelle méthode d'extraction de texte à partir des documents hétérogènes scannés incluant des régions de texte avec un fond complexe ou homogène. Dans cette méthode, un processus d'analyse d’image est employé suivi d’une classification des régions du document en régions d’images (texte avec un fond complexe) et de textes (texte avec un fond homogène). Pour les régions de texte on extrait l'information textuelle en utilisant une méthode de classification hybride basée sur l'algorithme Kmeans (CHK) que nous avons développé. Les régions d'images sont améliorées avec une Correction Gamma (CG) avant d'appliquer CHK. Les résultats obtenus d'expérimentations, montrent que notre méthode d'extraction de texte permet d'attendre un taux de reconnaissance de caractères de 98,5% sur des documents hétérogènes scannés.Un Descripteur de Caractère Unifié basé sur l'étude de la structure des caractères. Il emploie un nombre suffisant de caractéristiques issues de l'unification des descripteurs de la projection horizontale et verticale des caractères réalisantune discrimination plus efficace. L'avantage de ce descripteur est à la fois sa haute performance et sa simplicité en termes de calcul. Il supporte la reconnaissance des reconnaissance de caractère de 100% pour une fonte et une taille données.Une parallélisation du système de reconnaissance de caractères. Le processeur graphique GPU a été employé comme une plateforme de parallélisation. Flexible et puissante, cette architecture offre une solution efficace pour l'accélération des algorithmesde traitement intensif d'images. Notre mise en oeuvre, combine les stratégies de parallélisation à fins et gros grains pour accélérer les étapes de la chaine OCR. En outre, les coûts de communication CPU-GPU sont évités et une bonne gestion mémoire est assurée. L'efficacité de notre mise en oeuvre est validée par une expérimentation approfondie / The Optical Character Recognition (OCR) is a process that converts text images into editable text documents. Today, these systems are widely used in the dematerialization applications such as mail sorting, bill management, etc. In this context, the aim of this thesis is to propose an OCR system that provides a better compromise between recognition rate and processing speed which allows to give a reliable and a real time documents dematerialization. To ensure its recognition, the text is firstly extracted from the background. Then, it is segmented into disjoint characters that are described based on their structural characteristics. Finally, the characters are recognized when comparing their descriptors with a predefined ones.The text extraction, based on binarization methods remains difficult in heterogeneous and scanned documents with a complex and noisy background where the text may be confused with a textured background or because of the noise. On the other hand, the description of characters, and the extraction of segments, are often complex using calculation of geometricaltransformations, polygon, including a large number of characteristics or gives low discrimination if the characteristics of the selected type are sensitive to variation of scale, style, etc. For this, we adapt our algorithms to the type of heterogeneous and scanned documents. We also provide a high discriminatiobn between characters that descriptionis based on the study of the structure of the characters according to their horizontal and vertical projections. To ensure real-time processing, we parallelise algorithms developed on the graphics processor (GPU). Our main contributions in our proposed OCR system are as follows:A new binarisation method for heterogeneous and scanned documents including text regions with complex or homogeneous background. In this method, an image analysis process is used followed by a classification of the document areas into images (text with a complex background) and text (text with a homogeneous background). For text regions is performed text extraction using a hybrid method based on classification algorithm Kmeans (CHK) that we have developed for this aim. This method combines local and global approaches. It improves the quality of separation text/background, while minimizing the amount of distortion for text extraction from the scanned document and noisy because of the process of digitization. The image areas are improved with Gamma Correction (CG) before applying HBK. According to our experiment, our text extraction method gives 98% of character recognition rate on heterogeneous scanned documents.A Unified Character Descriptor based on the study of the character structure. It employs a sufficient number of characteristics resulting from the unification of the descriptors of the horizontal and vertical projection of the characters for efficient discrimination. The advantage of this descriptor is both on its high performance and its simple computation. It supports the recognition of alphanumeric and multiscale characters. The proposed descriptor provides a character recognition 100% for a given Face-type and Font-size.Parallelization of the proposed character recognition system. The GPU graphics processor has been used as a platform of parallelization. Flexible and powerful, this architecture provides an effective solution for accelerating intensive image processing algorithms. Our implementation, combines coarse/fine-grained parallelization strategies to speed up the steps of the OCR chain. In addition, the CPU-GPU communication overheads are avoided and a good memory management is assured. The effectiveness of our implementation is validated through extensive experiments

Une propriété d'un objet est dite opaque pour un observateur si celui-ci ne peut déduire que la propriété est satisfaite sur la base de l'observation qu'il a de cet objet. Supposons qu'un certain de nombre de propriétés (appelées secrets) soient attachées à chaque intervenant d'un système, nous dirons alors que le système lui-même est opaque si chaque secret d'un observateur lui est opaque : il ne peut percer aucun des secrets qui lui ont été attachés. L'opacité a été étudié préalablement dans le contexte des systèmes à événements discrets où différents jeux d'hypothèses ont pu être identifiés pour lesquels on pouvait d'une part décider de l'opacité d'un système et d'autre part développer des techniques pour diagnostiquer et/ou forcer l'opacité. Cette thèse constitue la première contribution au problème de l'opacité des artefacts d'un système à flots de tâches (système workflow). Notre propos est par conséquent de formaliser ce problème en dégageant les hypothèses qui doivent être posées sur ces systèmes pour que l'opacité soit décidable. Nous indiquons quelques techniques pour assurer l'opacité d'un système. / A property (of an object) is opaque to an observer when he or she cannot deduce the property from its set of observations. If each observer is attached to a given set of properties (the so-called secrets), then the system is said to be opaque if each secret is opaque to the corresponding observer. Opacity has been studied in the context of discrete event dynamic systems where technique of control theory were designed to enforce opacity. This thesis is the first attempt to formalize opacity of artifacts in data-centric workflow systems. We motivate this problem and give some assumptions that guarantee the decidability of opacity. Some techniques for enforcing opacity are indicated.

As organizações precisam trocar informações de forma simples e eficiente, com custos tão baixos quanto possível. Essas informações às vezes são apresentadas na forma de documentos com formato e conteúdos pré-definidos. Esses documentos podem ser equivalentes ou quase equivalentes, porém bastantes distintos em diferentes organizações. Numa mesma organização, os documentos podem ser diferentes em contextos históricos. O propósito deste trabalho é facilitar a distribuição dos documentos, superando o problema dos formatos com os quais foram criados. O objetivo é possibilitar a interoperabilidade de documentos e atingir a portabilidade simples e confiável de documentos através da reutilização de formatos e conteúdos, em diferentes combinações plausíveis. Propomos, usar ontologias como solução ao problema da falta de interoperabilidade nas implementações de formatos de documentos. Como prova de conceito consideramos a portabilidade entre os formatos padrão ODF(Open Document Format) e (Office Open XML). / Organizations need to exchange information simple and efficient, with costs as low as possible. Such information is sometimes presented as documents and with pre-defined content. These documents may be equivalent or nearly equivalent, but quite distinct in different organizations. In the same organization, documents can be different historical contexts. The purpose of this work is to enable interoperability of documents and achieve portability of digital documents through the reuse of content and format in different plausible combinations. We propose the characterization of digital documents using ontologies as a solution to the problem of lack of interoperability in the implementations of document formats. As proof of concept we consider the portability between ODF(Open Document Format) and OOXML (Office Open XML) document formats.
