Com a rápida evolução tecnológica e o crescimento da aplicação de novas tecnologias digitais na educação - em especial em cursos a distância - o mais importante tem sido a criação de novos ambientes de aprendizagem que estimulam a interatividade, desenvolvem a capacidade de formular, de resolver questões e, acima de tudo, possibilitam a participação de forma colaborativa, embora estando fisicamente distante. A idéia de uma escola \"expandida\" visa atender a diversas áreas de ensino, entre elas a necessidade de treinamentos no setor corporativo para os profissionais que já estão no mercado de trabalho, a formação escolar para jovens e adultos que enfrentam dificuldades pela distância ou indisponibilidade de horário, ou mesmo a qualificação docente em grande demanda por aperfeiçoamento. Para atingir um nível bom de participação em encontros virtuais, faz-se necessário contar com tecnologias de comunicação e informação que medeiam a interação entre os envolvidos no processo de ensino. Afinal, a aprendizagem, que não é apenas individual mas coletiva, se baseia na convivência entre os participantes, na troca de informações entre eles. Quando um conteúdo é ministrado a distância, por meio da Internet, em videoconferência, permite-se criar um espaço ideal para uma colaboração distribuída. Por conta dessa necessidade, este trabalho apresenta um ambiente que oferece a comunicação por vídeo, voz e texto, para aulas ao vivo entre vários participantes, cuja participação é controlada pelo moderador, ao mesmo tempo em que conta com um sistema de registro de atividades para interação assíncrona. Além do ambiente desenvolvido, o trabalho introduz um breve estudo de conceitos envolvidos na videoconferência, as tecnologias disponíveis, bem como as utilizadas para o desenvolvimento deste projeto. Alguns resultados foram obtidos após realização de testes e utilização do ambiente, tal como a análise de desempenho a partir dos recursos disponíveis na rede. / With the fast technological evolution and the growth of the new digital technologies application in the education, in special in long-distance education courses is observed that the majority of these courses has favored great parcel of people.

Depuis le 1er janvier 2016, un nouveau Code de procédure civile est entré en vigueur pour faire passer la justice civile québécoise au XXIe siècle. Bien plus qu’une simple réforme, c’est une « nouvelle culture judiciaire » qui est encouragée, assurant des solutions adaptées aux besoins des justiciables. Dans cette perspective, il convient désormais, selon la lettre du Code, de «privilégier l’utilisation de tout moyen technologique approprié», c’est-à-dire satisfaisant au principe de proportionnalité. Une telle proposition, anodine de prime abord, est en réalité assez inédite : un principe relativement ancien – la proportionnalité procédurale – vient réguler un objet nouveau – les technologies de l’information. La présente thèse vise en ce sens à identifier toutes les ramifications et implications d’une telle approche, et ce, en deux temps successifs. Dans un premier temps, nous délimiterons la notion juridique de proportionnalité procédurale, qui a été relativement peu étudiée jusqu’à présent. Quant à ses origines, le principe de proportionnalité remonte à des millénaires avant notre ère, et n’a cessé de gagner de l’importance dans de nombreux domaines de droit : c’est donc l’histoire d’un «succès en puissance». Néanmoins, ce n’est qu’au milieu du XXe siècle, dans un contexte de crise de la justice civile et sous l’influence des théories utilitaristes, que la proportionnalité s’est développée en procédure civile (d’abord aux États-Unis, puis en Angleterre, pour ensuite percoler dans plusieurs autres juridictions). Ainsi, au Québec, la proportionnalité est aujourd’hui érigée en principe directeur de la procédure civile, qui porterait un véritable «effet système». Cette réussite n’est toutefois pas unanime puisque d’autres pays civilistes, dont la France au premier plan, relèguent la proportionnalité à l’état de simple concept, à la croisée de nouveaux principes managériaux (qualité, efficacité, célérité, etc.). Dans un deuxième temps, nous dégagerons l’action technologique que peut jouer le principe de proportionnalité procédurale. Selon nous, la nouvelle «procédure technologique», fondée sur la transmission technologique des actes et les technologies audiovisuelles, est insuffisante à elle seule : il s’agit d’un amas de règles techniques, sans cohérence, sans cohésion, trop mécaniques. Le principe de proportionnalité, appliquée aux moyens technologiques, apparaît alors comme une piste intéressante pour unifier et humaniser cette procédure technologique. Concrètement, le tribunal devrait autoriser, refuser ou ordonner le recours aux moyens technologiques selon une appréciation in concreto et in globo des intérêts en jeu. Par exemple, dans le cas d’un litige complexe, un témoignage à distance du témoin principal par Skype qui vivrait à côté du Palais de justice, devrait être refusé, car manifestement disproportionné. On voit alors poindre un sous-principe émergent de «proportionnalité technologique» qui aurait sa propre définition, son propre test, ses propres finalités. Plus avant, le juge devrait désormais assumer un nouvel office par rapport aux technologies de l’information, notamment en faisant des choix technologiques, en assurant une forme de Technology Assessment. Au bout du compte, une telle approche, qui se développe dans le contexte québécois, offre un discours assez inédit sur la technique en procédure civile : la proportionnalité n’est ni reniée (passé, tradition, juridico), les technologies ne sont ni rejetées (avenir, innovation, technico), l’un et l’autre doivent être indissociables. C’est donc un message en trois mots que porte la présente thèse : modernisation en modération. / January 1, 2016 marked the entry into force of the new Code of Civil Procedure, leading Québec’s civil justice system into the 21st century. This new Code is much more than a simple reform; rather, it encourages a wholly “new legal culture” by providing solutions adapted to the needs of its citizens. As such, to quote the Code itself, “appropriate technological means should be used whenever possible”, i.e. conforming to the principle of proportionality. This proposition may appear trivial upon first glance, but actually contains a fairly innovative reality: a well-established principle – that of procedural proportionality – now regulates a new area of activities – being information technologies. This thesis aims to identify all of the ramifications and implications of this application and will do so in two steps. First, we will begin by defining the legal concept of procedural proportionality, which has been relatively little studied until now. As to its origins, the concept of proportionality itself goes back millennia and, throughout time, has gained prominence in several fields of law: it is therefore the story of an ever-growing trend. That being said, it was only in the middle of the 20th century, against a backdrop of civil justice crises and under the influence of utilitarian theory, that proportionality was introduced as a matter of civil procedure (first in the United States, then in England, to finally percolate into other jurisdictions). In Québec, proportionality is today a guiding principle of procedure, which qualification has had a genuinely systemic effect. This gain is however not unanimous, as several other civil jurisdictions, France being the first, relegates proportionality to the rank of mere concept, theoretically located at the intersection of new managerial principles of civil procedure (such as quality, efficiency, celerity, etc.) In a second step, we will examine the practical technological effects of the principle of procedural proportionality. In our opinion, what we call “technological procedure” based on electronic transmission of documents and audiovisual technologies is insufficient in and by itself: it is only a mass of technical rules, without coherence or cohesion, much too mechanical. The principle of proportionality, applied to technologies, is therefore an interesting way to unify and humanise technological procedure. Concretely speaking, this means that a court should authorize, refuse or order the use of technologies according to an in concreto and in globo analysis of the interests at stake. For instance, in the case of a complex litigation, the use of Skype for the remote testimony of a main witness who lives next to the courthouse should be refused, since it is manifestly disproportional. In this manner, we are witnessing the emergence of a new sub-principle, what we call “technological proportionality” herein, which has its own definition, test and finalities. Furthermore, judges will henceforth have to assume a new role with respect to information technologies, notably by making technological choices and performing a form of “technology assessment”. In the end, such an approach, as it develops in Québec, offers a novel discussion on technology in civil procedure: neither proportionality (ancient, traditional, legal) nor technologies (futuristic, innovative, high-tech) are rejected; in fact, one cannot be dissociated from the other. The message of this thesis can therefore be summarised by three simple words: modernization in moderation.

De nos jours, le Cloud Networking est considéré comme étant l'un des domaines de recherche innovants au sein de la communauté de recherche du Cloud Computing. Les principaux défis dans un environnement de Cloud Networking concernent non seulement la garantie de qualité de service (QoS) et de sécurité mais aussi sa gestion en conformité avec un accord de niveau de service (SLA) correspondant. Dans cette thèse, nous proposons un Framework pour l'allocation des ressources conformément à un SLA établi de bout en bout entre un utilisateur de services Cloud (CSU) et plusieurs fournisseurs de services Cloud (CSP) dans un environnement de Cloud Networking (architectures d’inter-Cloud Broker et Fédération). Nos travaux se concentrent sur les services Cloud de types NaaS et IaaS. Ainsi, nous proposons l'auto-établissement de plusieurs types de SLA ainsi que la gestion autonome des ressources de Cloud correspondantes en conformité avec ces SLA en utilisant des gestionnaires autonomes spécifiques de Cloud. De plus, nous étendons les architectures et les SLA proposés pour offrir un niveau de service intégrant une garantie de sécurité. Ainsi, nous permettons aux gestionnaires autonomes de Cloud d'élargir leurs objectifs de gestion autonome aux fonctions de sécurité (auto-protection) tout en étudiant l'impact de la sécurité proposée sur la garantie de QoS. Enfin, nous validons notre architecture avec différents scénarios de simulation. Nous considérons dans le cadre de ces simulations des applications de vidéoconférence et de calcul intensif afin de leur fournir une garantie de QoS et de sécurité dans un environnement de gestion autonome des ressources du Cloud. Les résultats obtenus montrent que nos contributions permettent de bonnes performances pour ce type d’applications. En particulier, nous observons que l'architecture de type Broker est la plus économique, tout en assurant les exigences de QoS et de sécurité. De plus, nous observons que la gestion autonome des ressources du Cloud permet la réduction des violations, des pénalités et limite l'impact de la sécurité sur la garantie de la QoS. / Today, Cloud Networking is one of the recent research areas within the Cloud Computing research communities. The main challenges of Cloud Networking concern Quality of Service (QoS) and security guarantee as well as its management in conformance with a corresponding Service Level Agreement (SLA). In this thesis, we propose a framework for resource allocation according to an end-to-end SLA established between a Cloud Service User (CSU) and several Cloud Service Providers (CSPs) within a Cloud Networking environment (Inter-Cloud Broker and Federation architectures). We focus on NaaS and IaaS Cloud services. Then, we propose the self-establishing of several kinds of SLAs and the self-management of the corresponding Cloud resources in conformance with these SLAs using specific autonomic cloud managers. In addition, we extend the proposed architectures and the corresponding SLAs in order to deliver a service level taking into account security guarantee. Moreover, we allow autonomic cloud managers to expand the self-management objectives to security functions (self-protection) while studying the impact of the proposed security on QoS guarantee. Finally, our proposed architecture is validated by different simulation scenarios. We consider, within these simulations, videoconferencing and intensive computing applications in order to provide them with QoS and security guarantee in a Cloud self-management environment. The obtained results show that our contributions enable good performances for these applications. In particular, we observe that the Broker architecture is the most economical while ensuring QoS and security requirements. In addition, we observe that Cloud self-management enables violations and penalties’ reduction as well as limiting security impact on QoS guarantee.

L’obésité combinée avec le vieillissement augmente les risques de complication au niveau de la santé physique et fonctionnelle entraînant des incapacités physiques et limitations en termes de mobilité. Même s’il est reconnu que la nutrition, l’exercice et les thérapies comportementales peuvent atténuer ces complications, leurs intégrations comme habitude de vie semblent dépendre du partenaire et être une barrière. Ainsi, les gérontechnologies, comme l’exergame ou la vidéoconférence, semblent être des outils prometteurs permettant aux personnes âgées d’accéder à différents soins et d’améliorer leur santé. Les objectifs sont 1) Évaluer l’acceptabilité et la faisabilité de trois interventions non pharmacologiques via vidéoconférence au sein de couples âgés en surpoids et obèses et; 2) Explorer et comparer si ces trois approches engendrent des améliorations au niveau de la santé physique et fonctionnelle. 25 couples ont été recrutés, de ce nombre, 21 couples ont complété l’intervention et étaient aléatoirement répartis dans les groupes : 1) conseil en nutrition (NUT), 2) thérapie comportementale mixte (ALL) et 3) activité physique (AP). L’intervention comprenait 10 contacts répartis sur 16 semaines. Des mesures de la santé physique et fonctionnelle ont été prises avant (T0) et après l’intervention (T1) via vidéoconférence. L’acceptabilité a été évaluée à l’aide du questionnaire SUS et la faisabilité des 3 interventions a été déterminée à l’aide du pourcentage de présence et de rétention aux interventions. Des analyses statistiques non–paramétriques de Kruskal-Wallis, des tests exacts de Fisher et de Wilcoxon ont été réalisées. Les trois interventions semblent acceptables (Questionnaire SUS). La rétention était similaire entre les groupes (p>0,05) et jugée bonne ou très bonne avec 88% (groupe NUT), 100 % (groupe ALL) et 67 % (groupe AP). Concernant, les différences intragroupes, aucune différence significative, d’un point de vue statistique, pour le groupe NUT et le groupe ALL est observée. Seul le groupe AP s’améliore significativement, d’un point de vue statistique et clinique au niveau de la puissance estimée (10 levers de chaise (w); p=0,005; + 69W), de la force estimée (5 levers de chaise (sec); p=0,01, -3,82sec), et de l’endurance (levers chaise en 30 secondes (n); p<0,004; +7reps) des membres inférieurs, de l’équilibre (équilibre unipodal (x/60sec); p=0,033; +11,93sec) et des capacités fonctionnelles (SPPB (x/12); p=0,027; +1pt). Les trois interventions non-pharmacologiques réalisées par vidéoconférence semblent faisables et acceptables auprès de couples âgés en surpoids et obèses. De plus, seule l’intervention en activité physique a permis d’améliorer d’un point de vue statistique, la santé physique et fonctionnelle. / Introduction: Obesity combined with aging increases the risk of physical and functional health complications leading to physical disability and mobility limitations. While it is recognized that nutrition, exercise and behavioral therapies can reduce these complications, their integration as a lifestyle habit seems to be partner-dependent and a potential barrier. The gerontechnology, such as exergame or videoconferencing, seem to be a promising tools for older people to access different care and improve their health. Objectives: 1) To assess the acceptability and feasibility of three non-pharmacological interventions via videoconferencing in overweight and obese elderly couples and 2) To explore and compare whether these three approaches generate more improvement in physical and functional health. Methodology: 25 couples were recruited; of these, 21 couples completed the intervention and were randomly assigned to 1) nutrition counseling (NUT), 2) mixed behavioral therapy (ALL) and 3) physical activity (AP). The intervention comprised 10 contacts spread over 16 weeks. Measures of physical and functional health were taken before (T0) and after the intervention (T1) via videoconference. Acceptability was assessed using the SUS questionnaire and the feasibility of the 3 interventions was determined using the percentage of presence and retention. Non-parametric statistical analyses such as Kruskal-Wallis, exact Fisher test and Wilcoxon tests were performed. Results: All three interventions were acceptable (SUS questionnaire). Retention was similar between groups (p>0,05) and rated as good or very good at 88% (NUT group), 100% (ALL group) and 67% (AP group). Regarding intragroup differences, no statistical difference was observed between the NUT and ALL groups. Only the AP group showed a statistically and clinically significant improvement in terms of estimated power (10 chair lifts (w); p=0,005; + 69W), estimated strength (5 sit to stand (sec); p=0,01; -3.82sec), and endurance (30-second chair test (n); p<0,004; +7reps) of the lower limbs, balance (unipodal balance (x/60sec); p=0.033; +11,93sec) and functional abilities (SPPB (x/12); p=0.,27; +1pt). Conclusion: The three non-pharmacological interventions performed via videoconferencing appear feasible and acceptable in overweight and obese elderly couples. Moreover, only the physical activity intervention produced a statistical significant improvement in physical and functional health.
