Healthcare is an increasingly collaborative enterprise involving a broad range of healthcare services provided by many individuals and organizations. Grid technology has been widely recognized as a means for integrating disparate computing resources in the healthcare field. Moreover, Grid portal applications can be developed on a wireless and mobile infrastructure to execute healthcare processe...

Pervasive computing provides a means of broadening and deepening the reach of information technology (IT) in society. It can be used to simplify interactions with Web sites, provide advanced location-specific services for people on the move, and support all aspects of citizens’ life in the community. Integrating IT services into everyday life requires that we can sense the environment where ser...

In this paper, to deliver healthcare service pervasively, especially to the home space, we first discuss the status and activities on healthcare infrastructures and systems using mobile devices and sensor networks. We also provide the information and illustrate the reasons why home healthcare will be even more hot space in the near future. With the advance of wireless network, mobile devices be...

In pervasive computing environments, wide deployment of sensor devices has generated an unprecedented volume of atomic events. However, most applications such as healthcare, surveillance and facility management, as well as environmental monitoring require such events to be filtered and correlated for complex event detection. Therefore how to extract interesting, useful and complex events from l...

One of the biggest challenges for pervasive healthcare systems is to find a way to utilize the context information captured in the environment in a simple and functional form, making the relationship between different computer systems easy and providing computational resources in a transparent way. One of the most common forms of context representation, known as ontology, has an significant rol...

6 PERVASIVEcomputing 1536-1268/02/$17.00 © 2002 IEEE T he paperless office is an idea whose time has come, and come, and come again. To see how pervasive computing applications might bring some substance to this dream, I spoke recently with key managers and technologists at McKesson Corporation (San Francisco), a healthcare supplier, service, and technology company with US$50 billion in sales l...

In an environment of escalating healthcare costs, chronic disease management is particularly challenging, since, by definition such diseases have no foreseeable cure and if poorly managed typically lead to further, complicated secondary health issues, which ultimately only serve to exacerbate cost. Diabetes is one of the leading chronic diseases and its prevalence continues to rise exponentiall...

Nowadays, the Unified Modeling Language, UML, is almost universally accepted by the software industry as the modelling language. However, the language has severe shortcomings. While UML is well suited to model the static aspects of software systems, the language as it is currently standardised strongly needs improvements with respect to modelling behaviour. Thus, for development of software com...

Sensor data generated by pervasive applications are very diverse and are rarely described in standard or established formats. Consequently, one of the greatest challenges in pervasive systems is to integrate heterogeneous repositories of sensor data into a single view. The traditional approach to data integration, where a global schema is designed to incorporate the local schemas, may not be su...

OBJECTIVE To understand the experiences and support needs of people with advanced liver disease and those of their lay and professional carers to inform improvements in the supportive and palliative care of this rapidly growing but currently neglected patient group. DESIGN Multiperspective, serial interviews. We conducted up to three qualitative in-depth interviews with each patient and lay c...
