Tracebook : a dynamic checklist support system

It has recently been demonstrated that checklist scan enable significant improvements to patient safety. However, their clinical acceptance is significantly lower than expected. This is due to the lack of good support systems. Specifically, support systems are too static: this holds for paper-based support as well as for electronic systems that digitize paper-based support naively. Both approaches are independent from clinical process and clinical context. In this paper, we propose a process-oriented and context-aware dynamic checklist support system: Tracebook. This system supports the execution of complex clinical processes and rules involving data from Electronic Medical Record systems. Workflow activities and forms are specific to individual patients based on clinical rules and they are dispatched to the right user automatically based on a process model. Besides describing the Tracebook functionality in general, this paper demonstrates the support system specifically on an example application that we are preparing for a controlled clinical evaluation. At last we discuss the difference between Tracebook and other support systems which also rely on a checklist format

Extending the Interaction Flow Modeling Language (IFML) for Model Driven Development of Mobile Applications Front End

International audienceFront-end design of mobile applications is a complex and multidisciplinary task, where many perspectives intersect and the user experience must be perfectly tailored to the application objectives. However, development of mobile user interactions is still largely a manual task, which yields to high risks of errors, inconsistencies and ine ciencies. In this paper we propose a model-driven approach to mobile application development based on the IFML standard. We propose an extension of the Interaction Flow Modeling Language tailored to mobile applications and we describe our implementation experience that comprises the development of automatic code generators for cross-platform mobile applications based on HTML5, CSS and JavaScript optimized for the Apache Cordova framework. We show the approach at work on a popular mobile application, we report on the application of the approach on an industrial application development project and we provide a productivity comparison with traditional approaches

Designing a federated multimedia information system on the semantic web

A federated Web-based multimedia information system on one hand gathers its data from various Web sources, on the other hand offers the end-user a rich semantics describing its content and a user-friendly environment for expressing queries over its data. There are three essential ingredients to successfully deploy such a system. First, one needs a design methodology identifying different design phases and their underlying models which serve as a framework for the designer. Second, there must be a set of tools that are able to execute the design, i.e. they serve as the back-end of the information system instantiating the models with data coming from various Web sources. Third, there also must be an entry point for the end-user, where he is able to explore what the system can do for him and where he can formulate his queries. This paper is a follow-up of our previous work describing the Hera design methodology and contributes to all three issues above. In particular, it refines the existing methodology by presenting an explicit RDFS-based integration model and explains how the mediator uses this model to obtain query results. The issue of a user-friendly front-end is addressed by introducing our interface for browsing and querying RDFS-based ontologies

A model-driven approach for designing distributed web information systems

There is an apparent need for specifying the integration of multiple knowledge sources during the design of Web Information Systems (WIS) where the actual data is often retrieved from several content providers. Despite that, there exists very little work on integration within the context of WIS engineering and the related design methodologies in particular. We argue that this new context brings several additional requirements which must be dealt with in order to be able to successfully deploy distributed WIS. In this paper we elaborate a model that covers the integration phase of the WIS design trajectory. We centered our approach around the emerging data standard on the Semantic Web – RDF. The proposed integration model is able to reconcile many semantic heterogeneities that frequently occur among disparate RDF sources. We also address the issues of distributed RDF query processing and optimization, and test the performance of our framework
