RESUMEN

Estimating the number of people present in a given venue in real-time is extremely useful from a security, management, and resource optimization perspective. This article presents the architecture of a system based on the use of Wi-Fi sensor devices that allows estimating, almost in real-time, the number of people attending an event that is taking place in a venue. The estimate is based on the analysis of the "probe request" messages periodically transmitted by smartphones to determine the existence of Wi-Fi access points in the vicinity. The method considers the MAC address randomization mechanisms introduced in recent years in smartphones, which prevents the estimation of the number of devices by simply counting different MAC addresses. To solve this difficulty, our Wi-Fi sensors analyze other fields present in the header of the IEEE 802.11 frames, the information elements, to extract a unique fingerprint from each smartphone. The designed system was tested in a set of real scenarios, obtaining an estimate of attendance at different public events with an accuracy close to 95%.

RESUMEN

Internet of Things platforms for Smart Cities are technologically complex and deploying them at large scale involves high costs and risks. Therefore, pilot schemes that allow validating proof of concepts, experimenting with different technologies and services, and fine-tuning them before migrating them to actual scenarios, are especially important in this context. The IoT platform deployed across the engineering schools of the Universidad Politécnica de Madrid in the Moncloa Campus of International Excellence represents a good example of a test bench for experimentation with Smart City services. This paper presents the main features of this platform, putting special emphasis on the technological challenges faced and on the solutions adopted, as well as on the functionality, services and potential that the platform offers.

RESUMEN

Introducción: la realización de la circuncisión por motivos culturales o religiosos es una práctica cuya indicación no está bien definida dentro de nuestra práctica médica. El objetivo de nuestro trabajo es mostrar la diversidad de su práctica en España a fin de establecer un protocolo de actuación general con respecto a este tema. Material y métodos: se ha realizado una encuesta nacional en 49 centros públicos con disponibilidad de servicio de cirugía pediátrica, en la que se recogen datos epidemiológicos, descriptivos y de opinión tanto colectiva como del personal médico sobre las derivaciones recibidas para hacer circuncisión. Resultados: se enviaron 200 encuestas, de las que se obtuvieron un total de 142 respuestas, el 76,6% de los facultativos no realizan circuncisiones por motivo religioso en el ámbito público. El 89% de los pacientes vistos en consulta son derivados por su pediatra. Hasta el 65% de los médicos afirman que han tenido algún conflicto con la familia del paciente cuando rechazan la indicación de la circuncisión por esta razón. De los profesionales que aceptan la intervención, el 39% lo hace para evitar la cirugía en peores condiciones fuera del hospital. El 57% de los cirujanos desconoce si esta indicación está incluida en la cartera de servicios del Sistema Nacional de Salud. Conclusiones: en base a nuestra encuesta, la mayoría de los profesionales desconoce si esta indicación está dentro de la cartera de servicios y coinciden en la necesidad de tener un consenso de actuación. Es importante tener una actitud conjunta, conocer todas las opiniones, y crear un protocolo de manejo de esta situación


Introduction: the performance circumcision for cultural or religious reasons is a practice whose indication is not well defined within the scope of medical practice in Spain. The objective of this study was to illustrate the variability in its practice in Spain with the purpose of eventually establishing a general protocol on the subject. Material and methods: we conducted a nationwide survey of public hospitals with a paediatric surgery department to collect epidemiological and descriptive data and opinions, both general and from individual medical providers, on the referrals received for performance of circumcision. Results: we submitted 200 questionnaires and received 142 responses, and 76.6% of the responding physicians reported not performing circumcisions for religious reasons in their practice in the public health system. Of all patients seen for a consultation, 89% had been referred by their paediatricians. Up to 65% of doctors reported having conflict with families when they refused to perform circumcision for this indication. Of the professionals who agreed on religious reasons as an indication, 39% performed the surgery to prevent its being performed under poorer conditions outside a hospital. Of all paediatric surgeons, 57% did not know whether this indication is included among the services covered by the National Health System. Conclusions: based on our survey, most professionals do not know whether this indication is included in the services covered by the public health system and agree on the need of establishing a consensus guideline. We believe that it is important to have a homogeneous approach, to explore the opinions of the professional collective as a whole and to develop a general protocol for approaching this situation
