An Anesthesia Alert System based on Dynamic Profiles Inferred through the Medical History of Patients

Anesthesia Information Management Systems (AIMSs) have existed for many decades. However, how to turn patient records into strategic information to improve the anesthesia process is still a research challenge. We did not find systems that use data from previous procedures for issuing alerts. This data can prevent errors during procedures and aid on medical staff [...]

Integration of feature models: A systematic mapping study

Context The integration of feature models has been widely investigated in the last decades, given its pivotal role for supporting the evolution of software product lines. Unfortunately, academia and industry have overlooked the production of a thematic analysis of the current literature. Hence, a thorough understanding of the state-of-the-art works remains still limited. Objective This [...]

Ebenezer: um modelo para prevenção ubíqua de acidentes de trabalho

Neste artigo é proposto Ebenezer, um modelo de computação ubíqua para prevenir acidentes em um ambiente de trabalho inteligente. Sua principal característica é a notificação aos trabalhadores e aos usuários em geral sobre a presença de perigos nos arredores, para evitar riscos de acidentes. A aplicação e validação foram realizadas com os trabalhadores em [...]

Diagnosis of learner dropout based on learning styles for online distance learning

The amount of data generated by computer systems in Online Distance Learning (ODL) contains rich information. One example of this information we define as the Learner Learning Trail (LLT), which is the sequence of interactions between the students and the virtual environment. Another example is the Learner Learning Style (LLS), which is associated with the [...]

TrailCare: An indoor and outdoor Context-aware system to assist wheelchair users

This article proposes a computational system to assist wheelchair users, improving accessibility through ubiquitous computing technologies. TrailCare uses indoor and outdoor location information to assist wheelchair users, recording their trails and providing context-aware assistance. Trails are historical records of users’ displacements that can be used to develop strategic accessibility solutions, such as security management and [...]

SIGTE: A System for Management of Waiting Time in Hospital Emergencies

This article proposes an integrated system for management of waiting times in hospital emergencies, called SIGTE. The system minimizes the waiting time of patients in the hospital emergency queues of the Sistema Único de Saúde (SUS), balancing the demands of care and mitigating problems of overcrowding. The SUS guarantees the population free access to health [...]

INTERACT: Um modelo baseado em contextos para motivação de interações em Redes Sociais Educacionais

Redes Sociais Educacionais (RSE) podem proporcionar espaços de interação e trocas entre aprendizes, mas não garantem motivação para que estas aconteçam. O INTERACT se utiliza do histórico contextual dos usuários para potencializar interações entre usuários de RSE. Além do modelo, é apresentado o protótipo desenvolvido. A avaliação se deu com coleta de dados gerados pelas [...]

Spontaneous Social Network: toward dynamic virtual communities based on context-aware computing

Recent efforts regarding mobile social networks aim at connecting people in smart environments considering not only their social behavior but also their context. In this perspective, this work presents a model, named SSN, based on the concept of Spontaneous Social Network, which allows the interaction of people anywhere and anytime without the need of any [...]
