An information need (the problem) cannot be divorced from its context. The problem context determines the urgency, granularity of detail, authority, and level of certainty required for an acceptable answer and dictates the expertise and resources that can be brought to bear. The ...

In the NGN (Next Generation Networks) users can connect their Internet devices to different network technologies. In addition to a seamless communication, users desire new and personalized services. In this sense, this thesis exploits the context-aware information in NGN environm...

In the era of ubiquitous computing, a new kind of application has been gaining increased attention from the academic community, the socalled Context-aware mobile applications. Context-aware computing requires context information representation mechanisms that facilitate this type...

OBJECTIVE--To explore the mechanism of an amnesia marked by confabulations and lack of insight in a patient with an infarct of the right inferior capsular genu. The confabulations could mostly be traced back to earlier events, indicating that the memory disorder ensued from an in...

U -Learning environments seek to collect information about users' preferences and needs to formulate its context and make adjustments to their content and interface to suit the user's profile, whereas in traditional VLEs, such as Moodle, this profile is hardly considered. Added t...

Pervasive applications use context provision middleware support as infrastructures to provide context information. Typically, those applications use communication publish/subscribe to eliminate the direct coupling between components and to allow the selective information dissemin...

Cognitive functions rely on the extensive use of information stored in the brain, and the searching for the relevant information for solving some problem is a very complex task. Human cognition largely uses biological search engines, and we assume that to study cognitive function...

The Semantic Web envisages providing a broad range of services from various application domains on the Web. These services often work in a collaborative way and are based on decision-making tasks, which are performed better if they are able to take into account all the relevant i...

It is time to understand that biased information is everywhere. Clinicians need to review pharmaceutical information in context....

This paper provides an approach to assessing Quality of Context (QoC) parameters in a ubiquitous Ambient Assisted Living (AAL) environment. Initially, the study presents a literature review on QoC, generating taxonomy. Then it introduces the context management architecture used. ...

Advances in microelectronic processes have allowed smaller devices with more computation and communication power. Pervasive environment contains different devices like electronic sensor, actuators and mobile devices which interact with the person naturally after the context is kn...

Ubiquitous computing has became a revolution in terms of the user-computer interaction by providing technologies that seamlessly integrate themselves to people?s everyday life. Context-aware computing, which is an important research theme in ubiquitous computing, has been contrib...

The Electronic Health Record should, theoretically, aggregate all possible sources of information from a patient, no matter their location or storage format, and allow authorized people to access this information. However, in practice, the medical information systems are heteroge...

Because of the severe financial hardships associated with the transition to a market economy in the Newly Independent States (NIS) of the former Soviet Union, the Internet has become a major link to health care resources for many health care workers. In 1992, the University of Il...

Health sciences libraries have considerable potential as resources for both formal continuing professional education, as well as the informal continuing education that results from the professional's efforts to solve problems in daily practice. While there is a growing interest i...

This research is about the question of the access to information considering the recent context of Brazilian history marked by the transition from a military dictator-ship to a democratic system. The research was based on the case study about the access to documents of the Depart...

Analyzes the field interface between Information Science (SI) and Education relating the information socialization to the Paulo Freire scontributions, mainly from procedures specified in Pedagogy of the Oppressed, which can guide the formation of communicative context. At the end...

Introduction: The idea that the place where we live, in addition to individual characteristics, contributes to outcomes related to health has motivated the implementation of many epidemiological studies. In this perspective, it becomes critical to understand which dimensions of c...

Abstract Information Technology (IT) governance in small and medium-sized businesses is a subject that still requires more effort. Many of the studies that deal with this subject refer to large companies. IT governance structures, originally developed for the context of large ent...
