BACKGROUND Despite the disease burden imposed by respiratory diseases on children in Central America, there is a paucity of data describing the etiologic agents of the disease. AIMS To analyze viral etiologic agents associated with influenza-like illness (ILI) in participants reporting to one outpatient health center, one pediatric hospital, and three(More)
During the stage of system requirements gathering, model elicitation is aimed at identifying in textual scenarios model elements that are relevant for building a first version of models that will be further exploited in a model-driven engineering method. When multiple elements should be identified from multiple interrelated conceptual models, the complexity(More)
This paper addresses the need for supporting the design of user interfaces for workflow management systems. Based on the already existing task and domain models, an approach is proposed to design a workflow model that explicitly articulates its new concepts with respect to the concepts belonging to the task and the domain, but with some extensions. The(More)
— A user interface description language (UIDL) consists of a specification language that describes various aspects of a user interface under development. A comparative review of some selected user interface description languages is produced in order to analyze how they support the various stages of user interface development life cycle and development(More)
This paper addresses the need for designing user interfaces (UIs) to workflow information systems by adopting a model-centric approach. We introduce a conceptual workflow model to determine system func-tionalities of workflow. The model is exploited in order to systematically derive UIs to access these functional-ities. The workflow model is recursively(More)
BACKGROUND Recent influenza antiviral resistance studies reveal an alarming increase in both adamantanes and neuraminidase inhibitors (NAIs) resistant viral strains worldwide, particularly in Asia, Europe and the United States. OBJECTIVES In this study, we have evaluated influenza virus resistance in Central and South America. METHODS Influenza viruses,(More)
BACKGROUND Dengue virus (DENV) infection can range in severity from mild dengue fever (DF) to severe dengue hemorrhagic fever (DHF) or dengue shock syndrome (DSS). Changes in host gene expression, temporally through the progression of DENV infection, especially during the early days, remains poorly characterized. Early diagnostic markers for DHF are also(More)
A collection of user interface design patterns for workflow information systems is presented. Each Workflow User Interface Pattern (WUIP) is characterized by properties expressed in the PLML markup language for expressing patterns and augmented by additional attributes and models attached to the pattern: the abstract user interface and the corresponding(More)
The need for accessibility evaluation tools is motivated by several endogenous and exogenous reasons coming from the end user (the designer and the developer) and companies releasing information systems. Existing evaluation tools mainly concentrate on examining the code of Web pages: Web pages more and more frequently contain non-HTML parts that entirely(More)
