Tatouage des Images Médicales en Vue d'Intégrité et de Confidentialité des Données
2010
International audience; Dans l'objectif de contribuer à la sécurité de partage et de transfert des images médicales, nous présentons dans ce travail la méthode de tatouage multicouche. Cette dernière consiste à insérer dans l'image médicale les informations qui concernent la signature de centre hospitalier et les données du patient. Elle doit permettre d'assuré l'intégrité, la confidentialité des données lors de leur partage, et la robustesse aux différents types d'attaques (compression JPEG, Copier-coller, transformations géométriques, etc).
Evaluer un dispositif de formation à distance : Principes et retour d'expérience
2008
The multiplication of distance learning platforms and the complexity of some of those used within the university system raise questions. First of all, the stabilization of writing practices of digital documents. Secondly, the evaluation of these devices. We want to address this last point in this article. What is it possible to assess in this field? There are many dimensions of evaluation, depending on the angle chosen. We limit ourselves to an approach focused on evaluating the human-computer interface. The chosen testing ground is a website for law studies, developed by the University of Burgundy's further education section.
Du territoire au territoire par l'observation, prendre en compte la diversité des territoires et adapter les méthodes et les outils aux nouvelles dem…
2008
We propose a conceptual and graphical model of the territory built from an empirical intuitive and deductive approach of systemic paradigm of territorialization. This model is based on an individualized approach before being extended to the collective level. It is first seen in the context of the evolution of the concept in scientific thinking. Then, we introduce it in understanding the dynamics of the territory, under the paradigm of territorial intelligence, through observation and observatories that we adapt to the context of governance systems at different scales.

La mesure de l'efficacité scolaire par la méthode de l'enveloppe : test des filières alternatives de recrutement des enseignants dans le cadre du pro…

Data envelopment and school effectiveness: contract teachers' efficiency compared to civil servants in the Education for all process) In the context of EFA process, countries, in general the most depressed LDC, both constrained by scarcity of funding and urgency for expanding school access have set up new tracks for teacher recruitment on annually renewable contracts. Those teachers are often not professionally trained in regards with traditional pedagogical curricula. They receive much lower salaries than regular civil service teachers. This has been a controversial policy, but there is very limited evidence on the effectiveness or failure of contract teachers in improving student learning…
Territorial Intelligence Communicational and Community System (TICCS)
2009
Information and Communication Sciences and Territorial Intelligence concept maintain multiple relations today. The method of territorial observation Catalyse, carried by the European Network of Territorial Intelligence, proposes a modelling under the shape of what Jean-Jacques Girardot calls a territorial intelligence community system (TICS, Girardot 2008). It is by the organization of the structuralization of the information, and by the conception of the process of communication that this kind of system takes life, and it is these aspects which we détail here to illustrate that both notions bring mutually. Experiments of research-action led in France, in Spain and in Europe feed these refl…
Évaluer un document numérique : Principes et méthodes
2010
International audience; Lors d'une démarche d'évaluation, il est nécessaire de définir ce que l'on souhaite évaluer. Pour cela, il convient de considérer que l'utilisation d'un document numérique se situe dans le contexte d'une activité menée par l'intermédiaire d'un dispositif technique. L'utilisateur se trouve donc exposé à une double contrainte, celle de devoir trouver des informations, intégrer des connaissances nouvelles sur un domaine donné, résoudre un problème, et pour ce faire, utiliser, en même temps, un dispositif technique (un document numérique développé à cet effet). On comprend que cette double contrainte et cette structure de buts vont rendre ce type de …
Vers un environnement informatisé d'évaluation de la qualité ergonomique d'interfaces multimédia : Étude exploratoire
2000
Our objective is to encourage the human-computer interface designers to be more interested in the uses made of their product by taking into account to a higher degree the human-factor in the testing phase which often is too focused on technical aspects. We want to facilitate the integration of the user as a source of evaluation during the testing phase. Our aim is to offer the designer a software environment of practical tests that allow them to have their own products evaluated by their users. We undertook an experiment to explore the feasibility of this project.
