This study addresses the question of the respective impact of organizational vs. technical environment variables on the collaborative aspects of healthcare work situations. It analyzes the physicians-nurses communications during the medication use process, according to both the organization of their work and their technical environment. Participant observations, interviews and recording of the dialogs were performed in 4 hospitals functioning with either a CPOE or a Paper based system. The study (i) presents the identification and description of the communications' processes involving doctors-nurses face-to-face communications and the supports that mediate medication information and (ii) focuses on the amount of face-to-face communications depending on the organization of work and the technical system used. The analyses demonstrate that the organizational variables have a larger impact than the technical environment on the quality and quantity of the communications and cooperation activities. © 2010 IMIA and SAHIA.

The main objective of this work is to automate the conversion process of pedagogical images into information easily understandable by blind people and visually impaired people. This is performed by determining automatically the different areas of interest in the image, then identify each region by assigning it a texture which will be for example transformed in relief. The text present in the image is also detected, recognized and transformed in accessible text (in Braille text or vocal message). The solution that we offer by this work is to provide a tool that tries to find automatically the principal information conveyed by the image and then transmit it to blind people. © Springer International Publishing Switzerland 2016.

Objective: To compare the impact of CPOE implementation and of the workplace organizational determinants on the doctor-nurse cooperation and communication processes. Method: A first study was undertaken in eight different wards aimed to identify the different workplace organizations that support doctor-nurse communications'. A second study compared the impact of these organizations and of a CPOE on medication-related doctor-nurse communications. Results: The doctor-nurse communications could be structured into three typical workplace organizations: the common round, the briefing and the opportunistic exchange organizations. The results (i) confirmed the impact of the organizational determinants on the cooperative activities and (ii) demonstrated the CPOE system has no significant impact within a given workplace organization. Conclusion: The success of the implementation of HIT applications relies partly on the identification of the actual (and sometimes hidden) structuring variables of teamwork and ultimately on their control at the time of implementation to ensure the quality and safety of the patient care provided. © 2012 Elsevier Ireland Ltd.

Attention is drawn to emotionally salient stimuli. The present study investigates processing of emotionally salient regions during free viewing of emotional scenes that were categorized according to the two-dimensional model comprising of valence (unpleasant, pleasant) and arousal (high, low). Recent studies have reported interactions between these dimensions, indicative of stimulus-evoked approach or withdrawal tendencies. We addressed the valence and arousal effects when emotional items were embedded in complex real-world scenes by analyzing both eye movement behavior and eye-fixation-related potentials (EFRPs) time-locked to the critical event of fixating the emotionally salient items for the first time. Both data sets showed an interaction between the valence and arousal dimensions. First, the fixation rates and gaze durations on emotionally salient regions were enhanced for unpleasant versus pleasant images in the high arousal condition. In the low arousal condition, both measures were enhanced for pleasant versus unpleasant images. Second, the EFRP results at 140-170. ms [P2] over the central site showed stronger responses for high versus low arousing images in the unpleasant condition. In addition, the parietal LPP responses at 400-500. ms post-fixation were enhanced for stimuli reflecting congruent stimulus dimensions, that is, stronger responses for high versus low arousing images in the unpleasant condition and stronger responses for low versus high arousing images in the pleasant condition. The present findings support the interactive two-dimensional approach, according to which the integration of valence and arousal recruits brain regions associated with action tendencies of approach or withdrawal. © 2014 Elsevier Inc.

The relevance of the results of a decision support system in the MCO process (Maintenance in operational conditions) in general and maintenance activities in particular is based on effectiveness of the human resources management considering their skills. After the literature review related to the RCPSP (Resource Constrained Project Scheduling Problem), an approach is proposed to meet a real industrial need which declined in three stages: the mapping of maintenance service competencies, the formalization of constraints competencies and LP solving under constraints. © 2012 Lavoisier.

Today Enterprise Interoperability is considered as a key factor of successful collaboration. It was identified as a critical need that has to be taken into account all along the lifecycle of a manufactured product. To deal with this problem and to reduce complexity of the different systems of interest used when different companies have to collaborate together, Enterprise Architecture (EA) and Enterprise Modelling (EM) are considered as solutions to facilitate Enterprise Interoperability. Dealing with interoperability issues in the context of Product Lifecycle Management (PLM), we have to mention the importance of product data and process standards implementation as interoperability enablers. In order to address the complexity of PLM standards, we propose to apply a model-driven methodology for modelling these standards and the related collaboration scenarios. This approach intends to make standards more comprehensive and to better manage standards evolutions, but also to instantiate and re-use these “generic” standards models to specify specific business collaboration scenarios. This proposal aims also to facilitate the exchange, testing and simulation of standards implementations. In this paper, the focus is on the ISA 95 standard for manufacturing-PLM integration, with an exchange scenario between Enterprise Resource Planning (ERP) and Manufacturing Execution System (MES) based on ISA 95 standard. © IFIP International Federation for Information Processing 2015.

On the web, we can find dictionaries for viewing a sign of French Sign Language (FSL), from a word. However, finding a word from a sign is much more complicated. For this purpose, we propose to design a web application to find the meaning of a FSL sign in the French language from the sign's features. In order to do this, we have developed an intelligent system capable of learning and self-improving by feeding off the information presented to it during its use. We have managed to find a middle ground between the reliability of the results and the ergonomics of Human-Machine Interfaces (HMI). © 2014 Springer International Publishing.

This paper aims at illustrating some limitations of the systemic approach when willing to ensure the interoperability of PLM solutions within a Dynamic Manufacturing Network (DMN), based on e-Business PLM standards and their implementations, being industrial processes, methods, applications or Information & Communication Technologies (ICT) solutions. Indeed, addressing interoperability challenges in such a complex digital business eco-system calls for a holistic approach based on the "system" paradigm. Setting this way, a part of our goal is to underline the limits and drawbacks of such an approach as interoperability brakes and to derive the issues that must be addressed in terms of research in order to remove them. This paper introduces a new approach in order to set up a test bed environment for PLM standards. The required and proposed approach considers a PLM standard not only as a technical solution, but above all as a strategic solution for which it is mandatory to support and enhance discussions between enterprise, product/system, processes, ICT architects and designers. The proposed approach-for analyzing and assessing the relevancy of PLM standards regarding their usage in specific business contexts-will be illustrated with a multi-layer modeling language. This language is used to model standards-based business collaboration scenarios and to model the test bed environment that will enable the execution/simulation of this scenario and the assessment of related standards implementations regarding the business needs of the scenario. The addressed case study is based on a data exchange scenario between a customer production order scheduler and a supplier production order executer using the ISA 95 standard. From this example, the interoperability issues related to DMN system of systems will be identified, for which accurate test based methods will be defined in future work. © Springer International Publishing Switzerland 2015.
