Abstract
The DigiScope project aims at developing a digitally enhanced stethoscope capable of using state of the art technology in order to help physicians in their daily medical routine. One of the main tasks of DigiScope is to build a repository of auscultations (sound and medical related data). In this work, we present a preliminary analysis and study of the first auscultations performed on children of a Brazilian hospital. Results indicate that classifiers can be obtained that distinguish reasonably well patients with cardiac pathologies from those that do not have pathologies.

Abstract
Many heterogeneous and highly specialized software applications for eHealth were implemented and deployed by diverse health organizations, such as public and private hospitals and health care centers. The rational management of these eHealth assets together with their efficient and interoperable integration represents today a major hitherto unresolved challenge for the health sector at a global level. One of the present implications is the serious interoperability issues that arise by the lack of widely accepted standards for the homogeneous integration of the diverse identity and authentication mechanisms used by the eHealth applications ecosystem. Unfortunately this has not yet been a major infrastructure concern for the eHealth context and thus constitutes a major road block for the realization of these applications full integration potential. In this work a high level model and some critical infrastructure components are proposed. Together with the Portuguese eID smart-card, allowed to delineate a novel and more flexible infrastructure for secure identity management and authentication services for eHealth. The secure privacy oriented identity infrastructure proposed fits well the highly demanding and specific needs of a heterogeneous and integrated modern identity infrastructure for eHealth applications, precisely because it provides strong foundations, upon which more reliable, secure, trustworthy and inter-operable eHealth applications can be built.

Abstract
The confluence of education with the evolution of technology boosted the paradigm shift of the face-to-face learning to distance learning. In this scenario e-Learning plays an essential role as a facilitator of the teaching/learning process. However new demands associated with the new Web paradigm require that existent e-Learning environments characterized mostly by monolithic systems begin interacting with new specialized services. In this decentralized scenario the definition of a strategy of interoperability is the cornerstone to ensure the standardization communication among systems. This paper presents a definition of an interoperability strategy for an e-Learning environment at our School (ESEIG) called PEACE - Project for ESEIG Academic Content Environment. This new interoperability model relies on the application of several coordination and integration standards on several services, controlled by teachers and students, and included in the PEACE environment such as social networks, repositories, libraries, e-portfolios, intelligent tutors, recommendation systems and virtual classrooms.

Abstract
The Internet plays an important role in higher education institutions where Learning Management Systems (LMS) occupies a main role in the eLearning realm. In this chapter we aim to characterize the Internet and LMS usage patterns and their role in the largest Portuguese Polytechnic Institute. The usage patterns were analyzed in two components: characterization of Internet usage and the role of Internet and LMS in education. Using a quantitative approach, the data analysis describes the differences between gender, age and scientific fields. The carried qualitative analysis allows a better understanding of students' both motivations, opinions and suggestions of improvement. The outcome of this work is the presentation of the Portuguese students' profile regarding Internet and LMS usage patterns. We expect that these results can be used to select the most suitable digital pedagogical processes and tools to be adopted regarding the learning process and most adequate LMS's policies. © 2012, IGI Global.
