Conforme a complexidade de cada setor, se torna necessário considerar abordagens de projeto que tornariam os resultados desta metodologia mais eficazes e mensuráveis, como é o caso da Saúde. Alguns autores que vêm pesquisando a aplicação neste setor, sugerem uma possível integração do Design baseado em evidências (DBE) e do Design baseado em experiências (DBEx) para viabilizar que um projeto orientado pelo usuário seja implementado em larga escala. Em busca da investigação sobre a lógica de evidências, foi estudada uma ferramenta utilizada no setor de serviços chamada Mecanismo da Função Produção (MFP), que prevê a quantificação das perdas dos processos. O presente estudo teve como contexto o Intensivismo Adulto (CTI) de um hospital privado em Porto Alegre e aplicou um caso em Design de Serviços com a lógica das evidências através da ferramenta MFP, para o desenvolvimento de uma abordagem integrada. Foi utilizado o método de pesquisa-ação com a descrição de todo o processo de projeto e dos resultados obtidos. A partir das análises pode-se constatar que (i) o olhar das evidências contribui para replicações dos resultados do projeto em casos futuros, (ii) o MFP pode ser um argumento para justificar a realização de um projeto em Design e (iii) para a integração das experiências com as evidências no setor hospitalar, pode-se gerenciar o projeto de modo a destinar um tempo maior para o diagnóstico e para a implementação. / Service Design consists of a methodology that uses a set of tools to create solutions to improve users perception on services, which can be applied in many fields and contexts. As the complexity of each field, it is necessary to consider approaches that would make results of this methodology more effective and measurable, such as health sector. Some authors have been research application of Service Design in this sector, and suggest a possible integration of evidence-based design (EBD) and experience-based design (ExBD) to enable a user-oriented design on a large scale implementation. In search on the logic of evidence, we studied a tool used in service sector called Mechanism of the Production Function, that provides quantification of loss processes. The present study was context in Intensive Care Unit (ICU) of a private hospital in Porto Alegre and applied a case of Service Design with the logic of the evidence through MFP tool for the development of an integrated approach. We used the method of action research with the description of the whole design process and results. From the analysis it was found that (i) the look of the evidence contributes to replication of project outcomes in future cases, (ii) MFP is an argument supporting the realization of a Design project and (iii) to integrate experiences with evidence in the hospital sector, we can manage the project in order to devote more time to the diagnosis and implementation.

Le microscope à force atomique (AFM) fait partie des microscopies de champ proche dites à sonde locale. De par sa versatilité, un grand nombre de domaines des nanosciences tant en physique, que chimie ou biologie utilisent cette technique. Cependant, le champ d’investigation de la microscopie AFM classique est restreint temporellement et spatialement. En effet, en raison de sa limite de vitesse d’acquisition d’image et sa limite de caractérisation des interactions en surface, des études de dynamique moléculaire ou d’éléments sub-surface ne sont pas envisageables. Nous montrons donc que la caractérisation en volume est permise en utilisant une méthode d’imagerie non destructive, la microscopie de champ proche holographique ultrasonore (SNFUH). Cette méthode développée pour étudier à l.air et en liquide, a fourni des informations localisées en profondeur avec une haute résolution spatiale, en utilisant des fréquences de résonance dans la gamme du MHz. Une calibration a été effectuée sur des échantillons de structures enterrées ou non, réalisés par lithographie e-beam. Ces échantillons ont été utilisés pour ajuster les fréquences de résonance et comprendre la formation des images en mode acoustique (profondeur investiguée et inversion de contraste). Cet outil non invasif et innovant de caractérisation a donc été développé. Il présente un énorme potentiel pour des échantillons biologiques en termes de résolution et d’information. Les microscopes AFMclassique et acoustique SNFUH sont soumis à des contraintes de temps. Pour s’en affranchir, un prototype, le microscope à force atomique haute-vitesse (HS-AFM) a été développé par l’équipe du Professeur T. Ando à l’Université de Kanazawa (Japon). Il autorise ainsi le balayage à vitesse vidéo, i.e. 25 images/s, en milieu liquide. Nous avons amélioré le prototype avec une nouvelle génération de boucle d’asservissement et augmenté la zone de caractérisation. La résolution dépend fortement du levier utilisé. De plus une qualité d’image supérieure est obtenue grâce à l’utilisation de surpointes en carbone sur ces mêmes leviers. Finalement, nous montrons des résultats obtenus avec ces deux techniques de microscopies sur différents édi.ces biologiques en milieu liquide. Ainsi, avec le microscope AFM haute-vitesse, des dynamiques biomoléculaires ont pu être visualisées (ex : structures protéine-ADN) avec une résolution nanométrique. Puis une étude des changements conformationnels intracellulaires de kératinocytes vivantes dans leur milieu physiologique a été réalisée par microscopie acoustique SNFUH et montre la dégradation du matériel biologique. L’ensemble de ces résultats ouvre un nouveau champ d’investigation dans le domaine de la biologie. / The atomic force microscope (AFM) made part of scanning near-field probe microscopy. Thanks to its versatility, many fields as physics, chemistry or biology use this technique. However, the field of investigation of the classical AFM microscope is limited temporally and spatially. Indeed, due to his scan speed limitation and surface interaction caracterisation limitation, studies of molecular dynamics and sub-surface elements are not possible. We show that the volume caracterisation is permitted using a non-destructive imaging method, called Scanning Near-Field by Ultrasound Holography (SNFUH). This tool developed for study in air and liquid has provided depth information as well as spatial resolution at the nanometer scale using resonant frequencies of about range of MHz. Calibration has been performed on samples of buried or not structures made by e-beam lithography and have been used to adjust the resonant frequency and understand the acoustic image formation (depth investigation and contrast in-version). We have developed a non-invasive and innovative tool of characterization for biology : he presents a huge potential for biological samples in terms of resolution and information. Classical AFM and acoustic SNFUH microscopes are time resolution limited. To overcome this time constraint, a prototype, High Speed Atomic Force Microscope (HS-AFM), has been developed by the team of Prof. T. Ando, Kanazawa University (Japan). It allows a scan rate at video speed, i.e. 25 frames/s, in liquid medium. We have improved the prototype, through a new generation of feedback control and increased the scan area. The resolution depends strongly of the probe used. Moreover a better image quality is obtained through the use of carbon tips on these cantilevers. Finally, we show our results obtained with these two microscopy techniques about biological buildings in liquid environment. Thereby, with the HS-AFM microscope, biomolecular dynamics have been visualized (e.g. protein-DNA structures) with nanometric resolution. Then a study about intracellular conformational changes of keratinocytes living cells in their physiological medium has been realized by acoustic microscopy SNFUH and show deterioration of biological components. All of these results provide new insights in biology field.
