Impacts des smartphones et tablettes sur les interfaces applicatives: théorie et mise en œuvre actuelle

Les smartphones et les tablettes ont changé notre manière de concevoir les applications. Arrivés depuis 2007, ces supports n’ont cessé d’augmenter leur part de marché par rapport au seul compétiteur qu’était le PC. Ils ne peuvent plus être ignorés lors de la conception d’un produit applicatif informatique. Cependant, pour développer des applications pour ces nouveaux supports, plusieurs points doivent être pris en compte. Plusieurs sujets sont abordés dans ce travail. La première partie expliquera la montée en puissance de ces nouveaux appareils et leurs manières d’être utilisés. Ensuite, des pratiques actuelles concernant les éléments d’interfaces utilisateurs seront présentées. En effet, des recommandations pour la conception d’interfaces utilisateurs existent afin d’offrir la meilleure expérience à l’utilisateur final. De plus, quelques outils et méthodologies de développement seront détaillés pour comprendre comment concevoir des applications mobiles et web de nos jours. Une analyse d’une application, portant sur le respect des best practices des interfaces utilisateurs, sera présentée en se basant sur le point de vue d’une méthodologie. Le but de cette analyse est de montrer le respect et la prise de liberté concernant les pratiques actuelles expliquées dans ce travail. Finalement, on retrouvera une proposition de solution visant à faciliter et accélérer le développement d’applications pour le web et pour les nouveaux supports de manière native

ANÁLISE DE DUAS PROPOSTAS DE ATIVIDADE EXPERIMENTAL SOBRE MOMENTO DE UMA FORÇA NAS AULAS DE CIÊNCIAS PARA O ENSINO FUNDAMENTAL

The present study aims to compare two activities, conventional experimentation and experimentation in a virtual laboratory, for the teaching of Moment in the Physics classes of students belonged to 9th year of Middle School. In order to do this, an experimental script was prepared for each one of the both experimentation activities and discussed among them advantages and disadvantages in the preparation of the activity, in the execution by the teacher and in the execution by the student. The results of the comparisons demonstrated the particularities that each activity has; in addition, they have shown the importance of both, since the learning can occur in both types of experimentationO presente trabalho tem por objetivo comparar duas atividades, uma elaborada na forma de experimentação convencional e outra na forma de experimentação em laboratório virtual, para o ensino de Momento de uma Força nas aulas de Física dos estudantes do 9° ano do Ensino Fundamental II. Para tanto, foi confeccionado um roteiro experimental para cada uma das atividades e discutidas vantagens e desvantagens na preparação das mesmas, na execução pelo professor e pelo aluno. Os resultados das comparações foram significativos e demonstraram as particularidades que cada atividade possui, além de evidenciarem a igual importância de ambas, uma vez que a aprendizagem pode ocorrer nas duas formas de experimentação

Disseminated Fusarium infection in autologous stem cell transplant recipient

Disseminated infection by Fusariumis a rare, frequently lethal condition in severely immunocompromised patients, including bone marrow transplant recipients. However, autologous bone marrow transplant recipients are not expected to be at high risk to develop fusariosis. We report a rare case of lethal disseminated Fusariuminfection in an autologous bone marrow transplant recipient during pre-engraftment phase

Management of laryngopharyngeal reflux in Brazil: a national survey

International audienceIntroduction: Studies assessing the management of laryngopharyngeal reflux by otolaryngologists have reported an important heterogeneity regarding the definition, diagnosis, and treatment, which leads to discrepancies in the management of the patient. Information about the current knowledge and practices of Brazilian otolaryngologists in laryngopharyngeal reflux is lacking. Objective: To investigate the trends in management of laryngopharyngeal reflux disease among Brazilian otolaryngologists. Methods: A survey was sent by email to the members of the Brazilian Association of Otolaryngology-Head Neck Surgery. This survey has initially been conducted by the laryngopharyngeal reflux study group of young otolaryngologists of the International Federation of Otolaryngological Societies. Results: According to the survey responders, the prevalence of laryngopharyngeal reflux was estimated to be 26.8% of patients consulting in otolaryngology and the most common symptoms were globus sensation, throat clearing, cough and stomach acid reflux. Nasal obstruction, Eustachian tube dysfunction, acute and chronic otitis media, vocal fold nodules and hemorrhage were considered not associated with laryngopharyngeal reflux by the majority of responders. About 2/3 of Brazilian otolaryngologists based the diagnosis of laryngopharyngeal reflux on the assessment of both symptoms and findings and a positive response to empiric therapeutic trials. Proton pump inhibitor utilized once or twice daily, was the most commonly used therapeutic scheme. Only 21.4% of Brazilian otolaryngologists have heard about nonacid and mixed laryngopharyngeal reflux and the awareness about the usefulness of multichannel intraluminal impedance pH monitoring (MII-pH) was minimal; 30.5% of responders did not consider themselves as well-informed about laryngopharyngeal reflux. Conclusion: Although the laryngopharyngeal reflux-related symptoms, main diagnostic and treatment approaches referred by Brazilian otolaryngologists are consistent with the literature, the survey identified some limitations, such as the insufficient awareness of the role of laryngopharyngeal reflux in many otolaryngological conditions and of the possibility of non-acid or mixed reflux in refractory cases. Future studies are needed to establish international recommendations for the management of laryngopharyngeal reflux disease
