Application of Real-Time Locating in Health CareThis paper describes real-time locating technology and its possible use in health care. Real time locating may be applied in different segments of everyday life, including hospitals (medical equipment and devices, locating patients, and alarm in case of emergency), working environment (locating persons to control access to restricted areas or in case of fire to see if anyone has been trapped inside the building), sports, logistics, retail trade, and offices. Tagged hospital equipment is easy to trace inside hospital premises and the system makes it possible to track patients and staff, and to redistribute work in particular wards.

Ecg Interpretation

Electrocardiography (ECG) interpretation is an essential skill for physicians as well as for many other health care professionals. Continuing education is necessary to maintain these skills. The process of teaching and learning ECG interpretation is complex and involves both deductive mechanisms and recognition of patterns for different clinical situations (“pattern recognition”). The successful methodologies of interactive sessions and real time problem based learning have never been evaluated with a long distance education model. To evaluate the efficacy of broadcasting ECG rounds to different hospitals in the Southeastern Ontario region; to perform qualitative research to determine the impact of this methodology in developing and maintaining skills in ECG interpretation. ECG rounds are held weekly at Kingston General Hospital and will be transmitted live to Napanee, Belleville, Oshawa, Peterborough and Brockville. The teaching methodology is based on real ECG cases. The audience is invited to analyze the ECG case and the coordinator will introduce comments to guide the case through the proper algorithm. Final interpretation will be achieved emphasizing the deductive process and the relevance of each case. An evaluation will be filled out by each participant at the end of each session. Videoconferencing works through a vast array of internet LANs, WANs, ISDN phone lines, routers, switches, firewalls and Codecs (Coder/Decoder) and bridges. A videoconference Codec takes the analog audio and video signal codes and compresses it into a digital signal and transmits that digital signal to another Codec where the signal is decompressed and retranslated back into analog video and audio. This compression and decompression allows large amounts of data to be transferred across a network at close to real time (384 kbps with 30 frames of video per second). Videoconferencing communication works on voice activation so whichever site is speaking has the floor and is seen by all the participating sites. A continuous presence mode allows each site to have the same visual and audio involvement as the host site. A bridged multipoint can connect between 8 and 12 sites simultaneously. This innovative methodology for teaching ECG will facilitate access to developing and maintaining skills in ECG interpretation for a large number of health care providers.

This qualitative study explores informal caregivers’ experiences of supporting persons with dementia’s everyday life coping. In the future, there will be fewer health personnel, increased dementia prevalence and limited nursing home availability. Accordingly, close relatives may be compelled to assume greater care responsibilities. Knowledge concerning persons with dementia’s everyday coping from the perspective of informal caregivers remains insufficient, despite these people’s importance for those with dementia. This investigation analyses informal caregivers’ perceived challenges and pleasures in providing care, how home health care affects everyday life coping and the factors that are most important to informal caregivers in supporting care receivers.

The rapid advances in human-friendly and wearable photoplethysmography (PPG) sensors have facilitated the continuous and real-time monitoring of physiological conditions, enabling self-health care without being restricted by location. In this paper, we focus on state-of-the-art skin-compatible PPG sensors and strategies to obtain accurate and stable sensing of biological signals adhered to human skin along with light-absorbing semiconducting materials that are classified as silicone, inorganic, and organic absorbers. The challenges of skin-compatible PPG-based monitoring technologies and their further improvements are also discussed. We expect that such technological developments will accelerate accurate diagnostic evaluation with the aid of the biomedical electronic devices.

System Output

An adaptive control algorithm based on the RBF neural network (RBFNN) and nonlinear model predictive control (NMPC) is discussed for underwater vehicle trajectory tracking control. Firstly, in the off-line phase, the improved adaptive Levenberg–Marquardt-error surface compensation (IALM-ESC) algorithm is used to establish the RBFNN prediction model. In the real-time control phase, using the characteristic that the system output will change with the external environment interference, the network parameters are adjusted by using the error between the system output and the network prediction output to adapt to the complex and uncertain working environment. This provides an accurate and real-time prediction model for model predictive control (MPC). For optimization, an improved adaptive gray wolf optimization (AGWO) algorithm is proposed to obtain the trajectory tracking control law. Finally, the tracking control performance of the proposed algorithm is verified by simulation. The simulation results show that the proposed RBF-NMPC can not only achieve the same level of real-time performance as the linear model predictive control (LMPC) but also has a superior anti-interference ability. Compared with LMPC, the tracking performance of RBF-NMPC is improved by at least 43% and 25% in the case of no interference and interference, respectively.

Human Gestures

In this paper, we design a robust and friendly human–robot interface (HRI) system for our intelligent mobile robot based only on natural human gestures. It consists of a triple-face detection method and a fuzzy logic controller (FLC)-Kalman filter tracking system to check the users and predict their current position in a dynamic and cluttered working environment. In addition, through the combined classifier of the principal component analysis (PCA) and back-propagation artificial neural network (BPANN), single and successive commands defined by facial positions and hand gestures are identified for real-time command recognition after dynamic programming (DP). Therefore, the users can instruct this HRI system to make member recognition or expression recognition corresponding to their gesture commands, respectively based on the linear discriminant analysis (LDA) and BPANN. The experimental results prove that the proposed HRI system perform accurately in real-time face detection and tracking, and robustly react to the corresponding gesture commands at eight frames per second (fps).

5S-CQI-TQM is a management technique that is aimed at bringing satisfaction of staff as well as the patients through improvement of working environment. A cross-sectional comparative study was carried out among 226 respondents who were selected purposively from the selected study place from 1st January to 31st December 2017. Among 226 respondents, 113 were taken from Dhaka Medical College and another 113 were taken from Mugdha Medical College. Among 113 respondents, 56 respondents were health care providers and 57 respondents were health care receivers. The purpose of this study to compare the management of services in Total Quality Management implemented (Dhaka Medical College and Hospital) and non-implemented (Mugdha Medical College and Hospital) health facilities. A Semi-structured interviewer administered questionnaire and an observational check list were developed to collect the data. Separate questionnaire was used for health care providers and health care receivers. The statistical analysis was conducted using SPSS (statistical package for social science) version 20 statistical software. Significant statistical differences were found between TQM implemented and TQM non-implemented hospital regarding workload (p=0.043), hospital authority always seriously consider staff’s suggestions for the improvement of quality of service (p<0.001), employees always respect to each other in the hospital (p<0.001) and 35 (62.5%) service providers expressed satisfactory opinion regarding management of the hospital.

Improvised Music

When we improvise together in music and dance, our bodies, instruments, and environments not only interact; they become mutually dependent. A bassist's shoulder shifts, bow slides, instrument rings . . . vibrations bounce off the walls, reach the dancer's inner ear, filling the lungs, lunging toward the bassist's shoulder: these sounds, movements, spaces, and perceptions form a real-time feedback loop that blurs where you end and I begin. Recent research in embodied and situated cognition by scholars such as Clark and Chalmers (1998), Gallagher (2005, 2007), Hutchins (1995), Noë (2004), and Suchman (2007) provides a theoretical foundation for formalizing this continuity. This literature has inspired us to reconsider how cognitive processes we tacitly know within a specific aesthetic framework are in fact at work throughout everyday life. In four videos taken from an hour-long studio session recorded in February 2012, we explore these processes once again in our own practice, and offer reflections in the form of program notes that invite the audience to perform these connections themselves.
