We present an innovative smartphone-centric tracking system for indoor and outdoor environments, based on the joint utilization of dead-reckoning and computer vision (CV) techniques. The system is explicitly designed for visually impaired people (although it could be easily generalized to other users) and it is built under the assumption that special reference signals, such as painted lines, colored tapes or tactile pavings are deployed in the environment for guiding visually impaired users along pre-defined paths. Thanks to highly optimized software, we are able to execute the CV and sensor-fusion algorithms in run-time on low power hardware such as a normal smartphone, precisely tracking …
Environmental Stressors and Their Impact on Health and Disease with Focus on Oxidative Stress
2017
Epidemiological, preclinical and interventional clinical studies have demonstrated that environmental stressors are associated with health problems, namely cardiovascular diseases. According to estimations of the World Health Organization (WHO), environmental risk factors account for an appreciable part of global deaths and life years spent with disability. This Forum addresses the impact of the environmental risk factors such as traffic noise exposure, air pollution by particulate matter (PM), mental stress/loneliness, and the life style risk factor (water-pipe) smoking on health and disease with focus on the cardiovascular system. We will critically discuss the use of observatory/modifiab…
Sleep, alertness and alertness management among commercial airline pilots on short-haul and long-haul flights
2016
Item does not contain fulltext Airline pilots' sleep and on-duty alertness are important focus areas in commercial aviation. Until now, studies pertaining to this topic have mainly focused on specific characteristics of flights and thus a comprehensive picture of the matter is not well established. In addition, research knowledge of what airline pilots actually do to maintain their alertness while being on duty is scarce. To address these gaps in research knowledge, we conducted a field study on a representative sample of the airline pilots of a medium-sized airline. The sample consisted of 90 pilots, of whom 30 flew long-haul (LH) routes, 30 short-haul (SH) routes, and 30 flew both. A tota…
The best way to assess visually induced motion sickness in a fixed-base driving simulator
2017
Abstract Objective Driving simulator usage is becoming more widespread, yet many users still experience substantial motion sickness-like symptoms induced by optical flow, called visually induced motion sickness (VIMS). The Fast Motion sickness Scale (FMS) allows for continuous on-line assessment of VIMS. Using mixed models for ordinal data, this study investigated how to optimally analyze FMS data, and then used the resulting models to examine the development of symptoms over time in detail. Additionally, the study explored the impact of specific VIMS-inducing road elements. Methods Twenty-eight healthy young adults without prior simulator experience completed six courses on two days in a f…
When age means safety: Data to assess trends and differences on rule knowledge, risk perception, aberrant and positive road behaviors, and traffic cr…
2019
This data article examines the association between age, knowledge of traffic rules, risk perception, risky and positive behaviors on the road and traffic safety outcomes of cyclists. The data was collected using a structured self-administrable and online-based questionnaire, applied to a full sample of 1064 cyclists. The data contains 4 parts: descriptive statistics; graphical trends for each study variable according to age; Post-Hoc (Tukey-HSD) comparisons between cyclists classified in the different age groups; and, finally, the dataset for further explorations in this regard. For further information, it is convenient to read the full article entitled "Explaining Self-Reported Traffic Cra…
La représentation des causes de l'état de santé par les infirmiers et les points de vue envisagés des patients et des aidants naturels : une approche…
2008
This study examines the representation of the determining factors of patients' states of health in therapeutic care situations. We describe the average representation of experienced hospital nurses (n=44) and the differences which they consider to exist between their own and their patients' points of view. Taking as our starting point the purpose of the care provided and the asymmetry of the carer/patient relationship, we hypothesize, on the one hand, that nurses will have a representation of their patients' state of health which is based on the care to be provided, with the factors determining the state of health being necessarily perceived as having a general impact on patients' lives whi…
L’enfant visiteur en réanimation adulte : vécu psychologique de la visite et dispositifs d’accompagnement
2021
Resume Introduction Si les reanimations ont largement ouverts leur porte aux proches, la presence des enfants et adolescents visiteurs en reanimation reste une question sensible et dans une volonte de proteger l’enfant face a un environnement potentiellement traumatique, certains services refusent ou restreignent la visite aux enfants. Objectif Dans ce contexte, la question de savoir si la visite en reanimation constitue un risque psychologique pour l’enfant se pose. A partir d’une revue de la litterature, cet article discute du vecu de la visite chez l’enfant et l’adolescent, les methodologies de recherche mises en place aupres des enfants visiteurs, et enfin des dispositifs d’accompagneme…
Analyse du langage et analyse des discours : quelques applications en psychologie
2020
Resume L’analyse des discours est encore peu developpee en Psychologie. Elle offre pourtant a la fois un cadre theorique precis et des methodes d’analyses variees, qui permettent de traiter de problematiques au cœur de la psychologie et des missions des psychologues. Tout discours est le fruit d’une co-construction, il integre les perceptions croisees et les dynamiques relationnelles, interindividuelles et intergroupes. Il n’y a pas de frontiere entre celui qui le produit et celui qui le recoit, l’un est dans l’autre et l’autre dans l’un. Cette conception est particulierement pertinente lorsqu’il s’agit d’analyser ce qui se deroule au cœur des rapports sociaux, quel que soit le domaine d’in…
Experiencing Commercial Videos for Online Shopping
2018
In recent years online shopping has become a popular and convenient instrument for companies to buy and sell products. However, the design of these web-shops does not offer the rich multisensory experiences than physical retailing offers. In the paper we argue that audio-visual contents could provide dynamic multisensory information to offer more engaging experiences to the consumer, but to achieve this goal, audio-visual contents need to be adjusted to the cultural characteristics of the users. Despite controversies regarding universalism of the emotional experiences induced by perceptual processes, we present evidence that suggests cultural modulations of videos experiences. In the report…
