Current nurse call systems hinder the efficiency of nurses as the systems are not aware of the type of requested help and the context in which their help is required. To tackle these issues, we have developed an ontology-based nurse call system that automatically takes the patients' and caregivers' profiles and context into account when assigning calls to nurses by modelling this information in an ontology, i.e., a formal domain model. For example, current tasks of the nurses and trust relationship with patients are considered while allocating calls to caregivers. Focus is not only on creating a higher quality patient care, but also on distributing the workload more evenly over all caregivers. However, not in all hospital departments such a smart nurse call system will have a significant impact, e.g., geriatric versus emergency care. To gain insights into the total impact of a smart nurse call system, a dedicated discrete event simulation (DES) model is presented that tests its performance. Based on realistic nurse call logs and information gathered at representative hospital departments through interviews and observations, the simulation model allows optimizing decisions, modelled as rules based on the information captured in the ontology, to allocate calls to the best suited nurse. Several scenarios with a varying number of calls, staff members, etc. are tested to be able to define the effectiveness and the (dis)advantages of the ontology-based system with respect to the current one. In conclusion, recommendations are made towards improving the currently employed nurse call systems in hospitals.

The international standard of transport and storage of radiological images - DICOM, the National Electrical Manufacturers Association (NEMA) - was formed to integrate the industry segment in favor of a single model of operation, aiming above all integration, customization and possible economy. This methodology combines virtues, mainly by excluding the proprietary view of previous systems. The images of a radiological examination must be transmitted from source to receiver without interruption or delay, have a large volume of files and large size together (in megabytes). The international standard is designed to operate at optimum telecommunications environments - stable, secure and transmission rates of local networks. In order to enable the practice of medicine where there is the presence of health professionals, Telemedicine seeks the creation of technologies that enable its activity. Conventionally, these physical environments also lack virtuous telecommunications systems. The telecom environment in the State of Amazonas to clinical and hospital environments of the State Secretariat of Health of the Amazon is distributed via satellite to 128 kbps connections. The 62 cities of this state are in dense forest environments with high humidity, heavy rainfall and high rate of electrical storms. Currently, even in the state of Amazonas, is in use in 44 units and in installation phase in the remaining 21 hospitals of the State Government, transmitting full digital mammograms beyond satellite to the Medical Report Center, located at the Hospital Francisca Mendes (Manaus/AM) of Federal University of Amazonas. The system has been customized to the case and is able to carry more than 380,000 exams per year, coming from the State Hospitals for Medical Reports Center. A simulator of deployed communications equipment will be presented at the Congress, demonstrating its practicality and dynamism when compared to international systems.

We have investigated approaches in the literature to assess the quality of the software architectures of medical devices, and have found evidence that there is a lack of methodologies for evaluating the software architecture design aspects of medical devices that might affect system safety. Such evidences were identified when evaluating the software architecture of the FDA Generic Infusion Pump searching for architectural evaluation approaches available in the literature. In order to fill this gap, we propose a set of quality questions that focus on analyzing software architecture design aspects of medical devices aiming safety. We show arguments on why reference projects such as the FDA Generic Infusion Pump system must satisfy our new quality questions. The quality questions were integrated into a quality model commissioned by the Brazilian Health Ministery for the certification of medical devices.

3D medical video was forecasted to be one of the groundbreaking 3D video applications. These range from tele-consultation to 3D robotics surgery. Enabling 3D video in e-health applications results in the provision of more natural viewing conditions, improved diagnosis and accurate interventions in surgical procedures. The deployment of 3D video services in healthcare is made possible to some extent by the advanced capturing devices (e.g., 3D endoscopes), recent advances in wireless communication technologies (e.g., LTE-Advanced(LTE-A)) and 3D video display technologies. Remote robotic assisted surgery and surgery training (education for surgeons) can benefit in particular from 3D video technologies due to the added dimension of depth. This paper analyzes the quality of compressed 3D surgical video. Moreover, asymmetric encoding of 3D medical video without compromising the medical quality of experience (M-QoE) is investigated in this paper. The quality of the compressed 3D medical video with the proposed method is evaluated using a comprehensive subjective quality evaluation test involving 12 medical surgeons. The results show a slightly better perception with the proposed asymmetric coding method compared to reference symmetric compression method, however the difference is statistically insignificant.

Clinical decision-support functions of telemedicine systems use patient's monitored clinical data to support treatment of outpatients. However, the quality of monitored clinical data may vary due to performance variations of technological resources inside a deployed telemedicine system. This paper discusses models to compute quality of clinical data affected by quality of service provided by technological resources along the data processing and delivery chain between the point of monitoring and point of decision. We discuss prospective effects of quality of clinical data degradation on outpatient treatment with medical practitioners, and implement these effects in the clinical decision-making process during design time. Consequently, the designed telemedicine system is technological context and quality-aware and preserves patient's safety and treatment efficacy.

Recent technological trends on mobile/wearable devices and sensors have been enabling increasing number of people to collect and store their “life-logs” easily in their daily lives. Beyond exercise behavior change of individual user, our research focus is on the behavior change of teams, based on life-logging technologies and information sharing. In this paper, we propose and evaluate six different types of information sharing model among team members for their exercise promotion, leveraging concepts of “competition” and “collaboration”. According to our experimental mobile web application for exercise promotion and extensive user study among 64 total users for three weeks, the model with “external competition” technique resulted the most effective performance for competitive teams such as sport teams.

The main challenge of big data processing includes the extraction of relevant information, from a high dimensionality of a wide variety of medical data by enabling analysis, discovery and interpretation. These data are a useful tool for helping to understand disease and to formulate predictive models in different areas and support different tasks, such as triage, evaluation of treatment, and monitoring. In this paper, a case study based on a predictive model using the radial basis function neural network (RBFNN) combined with a filtering technique aiming the estimation of electrocardiogram (ECG) waveform is presented. The proposed method revealed it suitability to support health care professionals on clinical decisions and practices.

We have developed an electromagnetic generator to bury in subcutaneous area or abdominal cavity of the birds. As we can't use a solar battery, it is extremely difficult to supply a power for subcutaneous implantation such as biosensors under the skin due to the darkness environment. We are aiming to test the antigen-antibody reaction to confirm an avian influenza[1-2]. One solution is a very small generator with the electromagnetic induction coil. We attached the developed coil to chickens and pheasants and recorded the electric potential generated as the chicken walked and the pheasant flew. The electric potential generated by walking or flapping is equal to or exceeds the 10 V peak-to-peak at maximum. Even if we account for the junction voltage of the diode (300 mV), efficient charging of the double-layer capacitor is possible with the voltage doubler rectifier. If we increase the voltage, other problems arise, including the highvoltage insulation of the double-layer capacitor. For this reason, we believe the power generated to be sufficient.

A fuzzy controller to support older adults should be robust and respond effectively to real-life situations such as illumination changes, ambient noise, and decision-making in critical situations. Following this approach, this paper presents the general design of “SA3M”, an autonomous support system for older adults that implements facial recognition, voice response and the use of various sensors to prevent or alert dangerous situations (gas leaks, fires, etc.). Furthermore, this paper addresses the problem of automatic microphone sensitivity control (Automatic Gain Control) in the processing of voice commands. To validate the proposed approach, the fuzzy controller was tested with a wide range of ambient noise levels and produced promising results.
