Assessing vulnerabilities in IoT-based ambient assisted living systems

Ambient Assisted Living systems aim at providing automated support to humans with special needs. Smart Homes equipped with Internet of Things infrastructure supporting the development of Ambient Intelligence which can look after humans is being widely investigated worldwide. As any IT based system, these have strengths and also weaknesses. One dimension of these systems developers want to strengthen is security, eliminating or at least reducing as much as possible potential threats. The motivation is clear, as these systems gather sensitive information about the health of an individual there is potential for harm if that information is accessed and used by the wrong person. This chapter starts by providing an analysis of stakeholders in this area. Then explains the IoT infrastructure used as a testbed for the main security analysis methods and tools. Finally it explains a process to assess the likelihood of certain vulnerabilities in the system. This process is mainly focused on the design stage of a system. It can be iteratively combined with development to inform a developing team which system architectures may be safer and worth given development priority

L'utilisation du processus de clivage chez une patiente cas-limite: Réflexion diagnostique et psychopathologique

International audienceFrom a clinical case concerning an ambulatory pathological non-selfcare without associated clinical signs and with a notably good social and professional fitting, authors present a psychopathological discussion. They discuss differntial diagnosis between obsessional neurosis, psychosis and borderliner case.A partir d'un cas clinique concernant une incurie à domicile sans signes cliniques associés, et avec notamment une bonne adaptation socio-professionnelle, les auteurs développent une discussion psychopathologique. Après l'étude du diagnostic différentiel, entre névrose obsessionnelle, psychose et état-limite, les auteurs soutiennent l'utilisation de mécanismes de défense tels que le clivage massif, chez un sujet cas-limite

Development of an index based on ultrasonographic measurements for the objective appraisal of body condition in Andalusian horses

Body condition scoring (BCS) is an indirect measure of the level of subcutaneous fat; however, by measuring the subcutaneous fat thicknesses (SFT), the precision of the degree of fatness assessment is improved. The aims were: 1) to develop an alternative body fat scoring index (BFSI) based on ultrasonographic measurements; 2) to assess the agreement between BCS and the new index applied to Andalusian horses; 3) to adjust the BCS cut-off values (if necessary) for overweight and obesity in this breed. One hundred and sixty-six Andalusian horses were included in this cross sectional study. On each horse, BCS, body fat percentage (BF%) and ultrasonography of SFT at localized deposits were evaluated. According to BFSI five possible body categories were established. Only one horse (0.6%) was classified as emaciated, 9.0% as thin, 74.7% as normal, 11.4% as overweight and 4.2% as obese. Despite higher BCS and SFT values were observed compared to other breeds, most of the horses evaluated presented a normal body condition under the new BFSI. BCS and BFSI were significantly associated (p<0.001), however, the concordance was low (weighted Cohen’s kappa coefficient, 0.262 ± 0.071; p=0.004). Using BFSI, obese horses had significantly greater BF% than the rest of categories (p<0.001). BCS showed a good diagnostic accuracy for detection overweight (AUC = 0.759 ± 0.055; p<0.001) and obese (AUC = 0.878 ± 0.050; p=0.001) horses; redefining the cut-off values for overweight and obesity condition as 7.5/9 and 8.5/9 respectively in Andalusian horses

Commuting time and sickness absence of US workers

This paper analyzes the relationship between commuting time and days of sickness absence of US workers. Using data from the Panel Study of Income Dynamics for the years 2011 to 2017, we find that a 1% increase in the daily commute of workers is associated with an increase of 0.018 and 0.027% in the days of sickness absence per year of male and female workers, respectively. These results are robust for women when sample selection, missing variables, and health status are explored. Further exploration of this relationship shows that the positive relationship between commuting and sickness absence is concentrated in urban areas only, and is present in the intensive margin (hours) for men and the extensive margin (participation) for women. By uncovering how commuting time is related to sickness absenteeism, we contribute to the literature on the negative correlation between commuting and workers’ health and well-being

Evaluación de la información sanitaria disponible en Internet sobre las recomendaciones de vacunación frente al Meningococo B

Fundamentos. La calidad de la información sanitaria en internet preocupa a gobiernos y usuarios. Nuestro objetivo fue determinar en qué medida la información disponible en la red sobre las recomendaciones de vacunación frente al meningococo B se adhiere a lo indicado por el Ministerio de Sanidad español. Métodos. Estudio transversal realizado en abril de 2017. Se evaluó la adhesión de la información sobre recomendaciones de recibir la vacuna. La información se obtuvo a través de Google utilizando veinte palabras clave. Se utilizó la prueba chi-cuadrado para estudiar la asociación entre obtener información adherida y el tipo de origen de la misma. Resultados. Se analizaron 186 enlaces web. Se detectaron recomendaciones adheridas entre el 52, 2% (97/186) de los enlaces para la indicación en personas con deficiencia de properdina/factores terminales del complemento, y el 79, 6% para las situaciones de brotes. Vacunar a niños a partir de los dos meses de edad fue una recomendación no elaborada por el Ministerio que se detectó en el 72, 6% de los enlaces. Para cada una de las recomendaciones del Ministerio, los organismos oficiales de salud pública siempre proporcionaron información adherida. Medios de comunicación digitales aportaron con una frecuencia significativamente mayor, que las Sociedades Científicas, información adherida sobre vacunar a personas con deficiencia de properdina/factores terminales del complemento (OR: 2, 72; IC95%: 1, 18-6, 28) y asplenia (OR: 3, 83; IC95%: 1, 66-8, 86). Conclusiones. Se evidencia una dificultad para obtener información adherida a lo indicado por la ponencia de vacunación del Ministerio de Sanidad, Servicios Sociales e Igualdad. Se debe promocionar en los usuarios la consulta de páginas web de organismos oficiales de salud pública cuando busquen información sobre esta vacuna. Background. The quality of health information online is a concern to governments and users. Our objective was to determine the extent to which the information available online regarding meningococcal B vaccine recommendations adhere to the guidelines of the Spanish Ministry of Health. Methods. Cross-sectional study carried out in April 2017. The study assessed adherence of information regarding vaccine recommendations to official guidelines. The information was collected via Google with 20 keywords. The Chi-squared test was used to analyze the association between the adhered information and its origin. Results. In total, 186 web links were analyzed. Adhered recommendations were found in a range of links, from 52.2% (97/186) with an indication for people with properdin deficiency/termial component pathway deficiency, to 79.6% for outbreak situations. Vaccinating children from two months of age was a recommendation not issued by the Ministry that was found in 72.6% of the links. For each of the Ministry recommendations, official public health institutions always provide information adhering to them. Digital media provided information about vaccination adhering to official guidelines with a significantly higher frequency than scientific societies in cases of people with . properdin deficiency/terminal component pathway deficiency (OR: 2.72; 95%CI: 1.186.28) and asplenia (OR: 3.83; 95%CI: 1.66-8.86). Conclusions. We have observed a difficulty to obtain adhered information. Users must be encouraged to access websites of official public health institutions when looking for information about this vaccine
