PV-Alert: A fog-based architecture for safeguarding vulnerable road users
2017
International audience; High volumes of pedestrians, cyclists and other vulnerable road users (VRUs) have much higher casualty rates per mile; not surprising given their lack of protection from an accident. In order to alleviate the problem, sensing capabilities of smartphones can be used to detect, warn and safeguard these road users. In this research we propose an infrastructure-less fog-based architecture named PV-Alert (Pedestrian-Vehicle Alert) where fog nodes process delay sensitive data obtained from smartphones for alerting pedestrians and drivers before sending the data to the cloud for further analysis. Fog computing is considered in developing the architecture since it is an emer…
Job strain in public transport drivers: Data to assess the relationship between demand-control model indicators, traffic accidents and sanctions
2018
This Data in Brief (DiB) article examines the association between the Job Demand-Control (JDC) model of stress and traffic safety outcomes (accidents and sanctions) in public transport drivers (n = 780). The data was collected using a structured self-administrable questionnaire composed of measurements of work stress (Job Content Questionnaire), and demographics (professional driving experience, hours and days working/driving per week). The data contains 4 parts: descriptive statistics, bivariate correlations between the study variables, analysis of variance (ANOVA) and Post-Hoc comparisons between drivers classified different quadrants of the JDC model. For further information, it is conve…
The prevention of occupational risks todomestic workers and home carers in spain: The need to ratify ilo conventions 189 and 190
2021
La prevención de los riesgos laborales y de la violencia y acoso en el trabajo es una más de las asignaturas pendientes en el tratamiento y protección del trabajo doméstico y de cuidados en España. Las escasas referencias normativas, así como la ausencia de una decidida política preventiva en este sector, contrastan con las previsiones de dos Convenios de la OIT: el Convenio 189, sobre el trabajo decente para las trabajadoras y los trabajadores domésticos, del año 2011, y el Convenio 190, sobre la violencia y el acoso, de 2019, por lo que la anunciada ratificación de ambos exige una mirada crítica y un cambio hacia una auténtica perspectiva preventiva de los riesgos laborales de las trabaja…
Studying the Response of Drivers against Different Collision Warning Systems: A Review
2017
International audience; The number of vehicle accidents is rapidly increasing and causing significant economic losses in many countries. According to the World Health Organization, road accidents will become the fifth major cause of death by the year 2030. To minimize these accidents different types of collision warning systems have been proposed for motor vehicle drivers. These systems can early detect and warn the drivers about the potential danger, up to a certain accuracy. Many researchers study the effectiveness of these systems by using different methods, including Electroencephalography (EEG). From the literature review, it has been observed that, these systems increase the drivers' …
The Quest for Global Safety
2007
The authors present a systematic study on the factors that have influence on the establishment of the safety conditions ensuring the rise of Global Earthing Systems. Starting from the definition of Global Earthing System given by CENELEC Document HD 637 SI and from the results of the studies done on the last years on the interconnected earthing systems inside MV networks, the paper proposes some directions of deepening on the topic of Global Safety. Some of the themes whom the paper deals with are: the correct definition of proximity, interconnection and quasi-equipotentiality of the earth electrodes belonging to a Global Earthing System; the influence of the presence of HV/MV stations on h…
Activité physique et prévention des chutes chez les personnes âgées
2015
Les chutes chez les personnes âgées sont fréquentes : près d’une personne de plus de 65 ans sur trois et une personne de plus de 80 ans sur deux chutent chaque année. L’état de santé, les capacités fonctionnelles, les facteurs comportementaux ou les caractéristiques de l’environnement constituent autant de facteurs de risque. Au-delà des traumatismes physiques et psychologiques tels que la peur de tomber qui en résultent, les chutes peuvent entraîner des limitations fonctionnelles, une diminution de la qualité de vie, une perte d’autonomie voire une entrée en institution.Dans un contexte de vieillissement de la population, la prévention des chutes et la préservation de l’autonomie dans les …
Rewetting of a hot vertical surface by liquid sprays
2005
Hot surfaces rewetting interests several technological fields. A very important application is in nuclear reactors technology, where it governs the cooling of overheated fuel elements during hypothesized loss of coolant accidents (LOCAs). This phenomenon is also important in many normal processes and accidental situations taking place in conventional processes. For example when the integrity of metallic containers, filled by toxic or dangerous substances, is endangered by a hypothetical fire. The rewetting consists in the re-establishment of coolant in contact with metallic surfaces become dried due to high temperature. To this end cold liquid is injected on these surfaces via sprays or other …
Occupational exposure to home risk factors: analysis of physical and mental health condition of a group of Sicilian housewives
2016
INTRODUCTION: The work of housewives, in many ways, still lacks professional respect; particularly with respect to the neglect of exposure to risk factors such as: chemical, physical, biological, psychological and accidents. The purpose of this study is to analyze the possible impact of environmental risk factors on the physical and mental health of a group of Sicilian housewives. METHODS: We enrolled housewives living in Palermo and Catania and administered an anonymous questionnaire to obtain knowledge of three factors: (1) the habits of the respondents, (2) the type of house in which they lived and worked, (3) the diseases they suffered. We also administered them a hospital anxiety and d…
Improving reliability of road safety estimates based on high correlated accidents counts
2007
Calibrating a safety performance function (SPF) with many years of accident data creates a temporal correlation that traditional model calibration procedures cannot deal with. It is well known that generalized estimating equations (GEE) models are able to incorporate trends into accident data and thus overcome difficulties in accounting for correlation; the usual application of GEEs to safety analysis uses robust (or sandwich) estimates of regression coefficients under the independence hypothesis for the working correlation matrix. This practice is justified by the robustness of the GEE procedure against misspecification of the response correlation structure. Nevertheless, with this method,…
Toxicological investigations in a fatal and non-fatal accident due to hydrogen sulphide (H2S)poisoning
2019
Hydrogen sulphide (H2S) is one of the most toxic natural gas and represents a not rare cause of fatal events in workplaces. We report here a serious accidental poisoning by hydrogen sulphide inhalation involving six sailors. Three of them died while the other three survived and were transported to the emergency room. No greenish discolouration of the body, that could be a feature of these type of deaths, was observed at autopsy. Given that blood and/or urine H2S detection does not allow to discriminate if it is related to inhalation or to putrefactive processes, the determination of thiosulphate, H2S main metabolite, is decisive. The succession of fatal events reported here can be rebuilt b…
