Being in close social proximity to a stranger is generally perceived to be an uncomfortable experience, which most people seek to avoid. In circumstances where crowding is unavoidable, however, people may seek to withdraw their attention from the other person. This study examined whether social discomfort, as indexed by electrodermal activity, is related to a withdrawal of attention in 28 (m=8,...

BACKGROUND A patient's physical activity is often used by psychiatrists to contribute to the diagnostic process for mental disorders. Typically, it is based mostly on self-reports or observations, and hardly ever upon actigraphy. Other signals related to physiology are rarely used, despite the fact that the autonomic nervous system is often affected by mental disorders. AIM This study attempt...

background: patients awaiting surgery typically experience significant physical and psychological stress. vital signs and serum cortisol level are altered in response to anxiety. the aim of this study was to assess the effects of preoperative education on physiological indices and cortisol level of female patients undergoing elective surgeries. materials and methods: in this single-blinded rand...

1 The performance of traditional biometric identification systems is as yet unsatisfactory in certain 2 fields of application. For this reason other physiological or behavioral characteristics are recently be3 ing considered, using new electrical or physical signals linked to a person’s vital signs. This paper 4 examines the biometric characteristics of PCG (PhonoCardioGram) signals from cardia...

The Internet of Things (IoT) is a technological innovation that widely used in science, including the field health sciences. An intelligent monitoring system for elderly patients only one IoT applications might be developed This must implemented so doctors can ascertain patient's status and monitored from home rather than having to visit hospital checkups. Therefore, device required make it sim...

BACKGROUND AND PURPOSE The retinal and cerebral vasculature share similar anatomic, physiological, and embryological characteristics. We reviewed the literature, focusing particularly on recent population-based studies, to examine the relationship between retinal signs and stroke. Summary of Review- Hypertensive retinopathy signs (eg, focal retinal arteriolar narrowing, arterio-venous nicking) ...

We have developed a flexible physiological monitoring and analysis system for physiological studies in which data are obtained over extended periods. Our system uses low-cost personal computer hardware to concentrate data from existing multiple monitoring devices. All monitored parameters are displayed on a single screen and recorded in a single file. The system automates the process of physiol...
