High levels of air pollution are associated with adverse effects on public health. Pollutant concentrations are typically subject to a high spatial and temporal variability. To investigate and quantify potential relations between pollutant concentrations and health effects, e.g. cases of respiratory diseases, sophisticated geospatial tools and methods are required. Air pollutants are ubiquitous...

ABSTRACT Background: Monitoring internal exposure of individuals handling significant amounts of iodine-125 (I-125) for iodination is of great importance. These individuals are potentially exposed to external contamination, and internal contamination through inhalation, ingestion and intact skin absorption, to I-125. Considering radiological toxicity of this radionuclide its monitoring in the w...

Monitoring personal locations with a potentially untrusted server poses privacy threats to the monitored individuals. To this end, we propose a privacy-preserving location monitoring system for wireless sensor networks. In our system, we design two in-network location anonymization algorithms, namely, resourceand quality-aware algorithms, that aim to enable the system to provide high quality lo...

INTRODUCTION Electronic personal health record-based (ePHR-based) self-management systems can improve patient engagement and have an impact on health outcomes. In order to realize the benefits of these systems, there is a need to develop and evaluate heath information technology from the same theoretical underpinnings. METHODS Using an innovative usability approach based in human-centered dis...

Bring Your Own Device (BYOD) policies permit employees to use personal devices to access organizational information. Users gain convenience from the ability to work in geographically diverse locations, while organizations gain the benefit of increased productivity and reduced information technology expense. However, these symbiotic benefits come at a cost. Organizations’ security boundaries are...

In this work, a novel signal processing method is proposed to assist the Receiver Autonomous Integrity Monitoring (RAIM) module used in a receiver of Global Navigation Satellite Systems (GNSS) to improve the integrity of the estimated position. The proposed technique represents an evolution of the Multipath Distance Detector (MPDD), thanks to the introduction of a Signal Quality Index (SQI), wh...

X-ray machines that comply with the ISO requirements for calibrating personal dosimeters sometimes are not available in a world region, mainly in developing countries. This is used as an excuse for a lack of personal dosimeter calibration and, consequently, a lack of reliability in the individual monitoring programs. Considering the availability of x-ray machines in many hospitals, this work sh...

Personal health monitoring is especially necessary in a pandemic of COVID19 and based on objective subjective data. Modern medicine uses numerous diagnostic devices, many which are for personal monitoring. Applications mobile phones becoming more widespread, they make possibility constantly monitor vital signs person. However, the consolidation into single personalized database information dail...

Abstract Given the large impact that spectrum and intensity of light can have on people's health well-being, it is fundamental importance to understand properties received under normal living conditions. Historically, as research into biological responses has traditionally focused laboratory studies with controlled lighting conditions, little known about exposure outside experimental environmen...
