    In general, on-line medical consultation reduces time required for medical consultation induces improvement in the quality and efficiency of healthcare services. All major types of current e-health applications such as ECG, X-ray, video, diagnosis images and other common applications have been included in the scope of the study. In addition, the provision of Quality of Service (QoS) for the application of specific healthcare services in e-health, the scheme of priority for e-health services and the support of QoS in wireless networks and techniques or methods for IEEE 802.11 to guarantee the provision of QoS has also been assessed. In e-health, medical services in remote locations such as rural healthcare centers, ambulances, ships as well as home healthcare services can be supported through the applications of e-health services such as medical databases, electronic health records and the routing of text, audio, video and images. Given this, an adaptive resource allocation for a wireless network with multiple service types and multiple priorities have been proposed. For the provision of an acceptable QoS level to users of e-health services, prioritization is an important criterion in a multi-traffic network. The requirement for QoS provisioning in wireless broadband medical networks have paved the pathway for bandwidth requirements and the real-time or live transmission of medical applications. From the study, good performance of the proposed scheme has been validated by the results obtained. The proposed wireless network is capable of handling medical applications for both normal and life-threatening conditions as characterized by the level of emergencies. In addition, the bandwidth allocation and admission control algorithm for IEEE 802.16- based design specifically for wireless telemedicine/e-health services have also been presented in the study. It has been concluded that under busy traffic conditions, the proposed architecture can used as a feasible and reliable infrastructure network for telemedicine

    Today’s mobile devices have become increasingly powerful with enhanced features such as increased CPU power and memory, internet connectivity in multiple ways (multi-homing) and interfacing with external peripheral devices (for instance GPS receiver, medical sensors). The proliferation of these mobile devices combined with an increasing willingness of users to share information available on and around mobile device (e.g. location, user activity) has given rise to Mobile Virtual Communities (MVC). This way, social interaction is now feasible anywhere and anytime. In another paradigm referred to as telemedicine, information and communication technologies are being investigated and employed in areas such as health maintenance and alleviation, cure and prevention of diseases. In general, (mobile) virtual communities have been explored in the telemedicine domain where they were found to be promising in many cases. However, evidence for their effectiveness has yet to be established. With this background and based on our expertise with MVCs and telemedicine, we address a number of aspects including: 1) basic concepts in telemedicine and MVC and analysis of effectiveness and success factors of MVCs in the telemedicine domain; 2) a prototype architecture addressing mobility issues for the MVC in the telemedicine domain; and 3) reflection on the opportunities and research challenges involved in using MVCs in the telemedicine domain

    Animals play a profoundly important and intricate role in our lives today. Dogs have been human companions for thousands of years, but they now work closely with us to assist the disabled, and in combat and search and rescue situations. Farm animals are a critical part of the global food supply chain, and there is increasing consumer interest in organically fed and humanely raised livestock, and how it impacts our health and environmental footprint. Wild animals are threatened with extinction by human induced factors, and shrinking and compromised habitat. This review sets the goal to systematically survey the existing literature in smart computing and sensing technologies for domestic, farm and wild animal welfare. We use the notion of \emph{animal welfare} in broad terms, to review the technologies for assessing whether animals are healthy, free of pain and suffering, and also positively stimulated in their environment. Also the notion of \emph{smart computing and sensing} is used in broad terms, to refer to computing and sensing systems that are not isolated but interconnected with communication networks, and capable of remote data collection, processing, exchange and analysis. We review smart technologies for domestic animals, indoor and outdoor animal farming, as well as animals in the wild and zoos. The findings of this review are expected to motivate future research and contribute to data, information and communication management as well as policy for animal welfare

    The Interactive Medical Emergency Department (iMED): Architectural Integration of Digital Systems into the Emergency Care Environment

    In healthcare, the architectural response to the development of information technologies has largely been relegated to a reactive role, essentially waiting for systems to develop and simply accommodating them with appropriately sized spaces. Designing IT systems independently from, rather than integrally with, their environment impedes them from reaching their full potential as vital components in the delivery of care by creating a lack of flexibility, decelerating performance, and degrading the healing environment. The flexibility of the environment is compromised by fixed position, single user data systems which prevent it from actively adapting to changing conditions, especially during volumetric surges associated with mass casualty events. Additionally, the delivery of care is hindered by traditional data entry points which minimize the caregiver\u27s ability to utilize information effectively by increasing distances to, and wait times for, available platforms. Furthermore, the overall quality of the healing environment is degraded by the increasing amount of technological clutter which can be difficult to sanitize, intimidating to patients, and unsafe by frustrating care. Dissolving the disconnect between architectural environments and information technology can be achieved by devising architectural elements and treatment protocols which would fuse both entities together, creating a more holistic, digitally integrated setting in which to deliver care. Utilizing advances such as integrated wall interfaces and environmental sensor systems would improve the delivery of care by empowering users and architectural settings with the ability to effectively adapt to changing conditions, increase accessibility to information, and streamline care for improved patient outcomes. Replacing fixed position, single user data entry systems with environmentally integrated surface interfaces would improve flexibility and performance by creating a multitude of localized points to access data, as well as streamline and simplify the environment by eliminating technological clutter. The process in which to derive an architectural response to the thesis statement was initiated by performing a series of interviews with nationally prominent professionals in the fields of healthcare architecture and information technology, attending international design conferences, interning in health facilities, assembling a cross-disciplinary thesis committee, and conducting a thorough literature review. The thesis research phase began by studying the historical progression and significance of information technology in healthcare environments in order to discern the architectural role in the implementation of these systems. The research focus was then shifted to all areas of architecture, identifying applicable precedent studies in which the environmental integration of information technology had enhanced the quality of the setting, highlighting characteristics that would improve flexibility, performance, and outcomes in the field of healthcare. From this exploration, a series of typological selection criteria were developed in order to determine which area within the healthcare spectrum would best demonstrate the potentials of this union. The emergency care environment was selected as an appropriate vessel to implement the thesis, due to its need for flexibility in order to accommodate ever changing demographic needs, significant volumetric shifts, fast paced care delivery which is dependent on the rapid utilization of information, and high patient turnover rate requiring an efficient throughput processes. Specific problems relevant to contemporary emergency departments were then identified, including overcrowding, staffing issues, and inability to accommodate for volumetric surges, all of which stem from inadequate throughput methodologies. The thesis then explored how the fusion of digital modalities with architectural elements in the emergency care environment would remediate these problems by improving the throughput of the facility. To ensure the final design holistically satisfies the goal of improving the quality and effectiveness of emergency care through the environmental integration of information technology, a series of design principles were developed to serve as its basis. In order to optimize data flow, access to input areas must be maximized by conceiving the building as an interface, where spatial boundaries become digital connections. If integrated data systems are to be accessible from a universal architectural interface and respond in a safe and controlled manner, digital scanning technologies such as biometrics and RFID tagging must be fused with physical threshold conditions in order to enable the digital system\u27s recognition of its inhabitants. In an additional effort to maintain safety, maximize workability, and ensure a level of sterility in sensitive environments, the facility needs to be designed into layers of penetration, regulating access to only those users who meet proper security clearances. Furthermore, the facility needs to act like a sponge, easily expanding and contracting the layers of penetration in an effort to accommodate unpredictable volumetric increases during mass casualty events. In addition to increasing its capacity, the facility should also be prepared to appropriate adjacent, existing infrastructure for overflow shelter and staging operations during such events. The programmatic typology of a freestanding medical emergency department, in which there is no connection to an existing facility, was selected with the intention of deriving a pure condition which eliminated extraneous influences from diluting the focus of this thesis on the relationship between information technology and architecture. Although rare in the US, freestanding emergency care facilities are a viable option for expanding healthcare provider\u27s coverage, capturing areas with growing populations, and improving the regional capability to respond effectively during mass casualty events. The base program was derived from the Swedish Medical Issaquah Campus Freestanding Emergency Department in Seattle, Washington, and then modified to function as a Point of Distribution (POD) site during mass casualty events. A series of potential mass casualty event scenarios were then developed in order to effectively prepare conceptual simulations to test possible responses from the facility\u27s program. The thesis proposal consists of a freestanding, 40,000+ square foot Interactive Medical Emergency Department (iMED) located in Charleston, SC. The proposal is guided by an established set of design principles, aiming to improve the delivery of emergency care during daily operations and mass casualty surge events through the architectural integration of information technology. In order to provide a range of possible disaster response situations, the building was located in the densely populated peninsula area of Charleston, South Carolina, within a region which is susceptible to an assortment of mass casualty events (including hurricanes, earthquakes, and terrorist attacks). The final site within the urban context adheres to a set of established criteria, including placement on open, stable, elevated land adjacent to the major access arterials of I-26, Hwy 17, and Meeting Street. Additionally, the site was located within a rapidly expanding, non-historical sector of the city which is not part of an existing healthcare complex. By meeting regional and urban conditions defined in the criteria, the site\u27s location strengthens the facility\u27s ability to deliver care during both daily and surge conditions substantially

    Get PDF
    Background: Cognitive skills training for minimally invasive surgery has traditionally relied upon diverse tools, such as seminars or lectures. Web technologies for e-learning have been adopted to provide ubiquitous training and serve as structured repositories for the vast amount of laparoscopic video sources available. However, these technologies fail to offer such features as formative and summative evaluation, guided learning, or collaborative interaction between users. Methodology: The "TELMA" environment is presented as a new technology-enhanced learning platform that increases the user's experience using a four-pillared architecture: (1) an authoring tool for the creation of didactic contents; (2) a learning content and knowledge management system that incorporates a modular and scalable system to capture, catalogue, search, and retrieve multimedia content; (3) an evaluation module that provides learning feedback to users; and (4) a professional network for collaborative learning between users. Face validation of the environment and the authoring tool are presented. Results: Face validation of TELMA reveals the positive perception of surgeons regarding the implementation of TELMA and their willingness to use it as a cognitive skills training tool. Preliminary validation data also reflect the importance of providing an easy-to-use, functional authoring tool to create didactic content. Conclusion: The TELMA environment is currently installed and used at the JesĂşs UsĂłn Minimally Invasive Surgery Centre and several other Spanish hospitals. Face validation results ascertain the acceptance and usefulness of this new minimally invasive surgery training environment
