Las Tecnologías de la Información y de las Comunicaciones como parte del problema y de la solución del consumo energético

En el presente trabajo se describe la contribución, tanto negativa como positiva, de las Tecnologías de la Información y de las Comunicaciones (TIC) en el incremento del consumo de energía eléctrica y, en consecuencia, sus efectos medioambientales. Se incluye un análisis sobre la evolución y las tendencias del consumo global de las TIC, se define el límite inferior teórico del coste energético del procesamiento por bit de información, y se presentan estimaciones del consumo medio real, tanto por procesamiento como por transmisión a través de redes de datos. También se enumeran los frentes abiertos para paliar el problema. Se hace hincapié en que, para contribuir beneficiosamente a reducir el aumento del consumo energético debe considerarse como parámetro fundamental la eficiencia energética y, al hacer los diseños y evaluaciones de los sistemas informáticos, no hay que centrarse sólo en el tiempo de ejecución, la precisión de los resultados y la comodidad de la interfaz de usuario. Es responsabilidad del profesorado universitario transmitir estos conocimientos y concienciar del problema a los futuros profesionales dentro de los planes de estudio y las materias correspondientes.This paper describes the contribution, both negative and positive, of Information and Communication Technologies (ICT) in increasing the consumption of electrical energy and, consequently, to its environmental effects. An analysis of the evolution and trends of global ICT consumption is included, the theoretical lower limit of the energy cost of processing per bit of information is defined, and estimates of the real average consumption are presented, both for processing and for transmission through of data networks. The open fronts to alleviate the problem are also quoted. It is emphasized that, in order to contribute beneficially to reducing the increase in energy consumption, energy efficiency must be considered as a fundamental parameter and when designing and evaluating computer systems, not focus only on execution time, the precision of the results and comfort of the user interface. It is the responsibility of university teaching staff to transmit this knowledge and raise awareness of the problem among future professionals within the corresponding study plans and subjects.Este trabajo ha sido financiado parcialmente por el Ministerio de Ciencia, Innovación y Universidades y por fondos FEDER a través de los proyectos PGC2018-098813-B-C31 y PGC2018-098813-B-C32

Energy Efficiency of Personal Computers: A Comparative Analysis

The demand for electricity related to Information and Communications Technologies is constantly growing and significantly contributes to the increase in global greenhouse gas emissions. To reduce this harmful growth, it is necessary to address this problem from different perspectives. Among these is changing the computing scale, such as migrating, if possible, algorithms and processes to the most energy efficient resources. In this context, this paper explores the possibility of running scientific and engineering programs on personal computers and compares the obtained power efficiency on these systems with that of mainframe computers and even supercomputers. Anecdotally, this paper also shows how the power efficiency obtained for the same workloads on personal computers is similar to that obtained on supercomputers included in the Green500 ranking.Spanish GovernmentEuropean Commission PGC2018-098813-B-C31 MICI

A Bayesian approach to study the risk variables for tuberculosis occurrence in domestic and wild ungulates in South Central Spain

Background: Bovine tuberculosis (bTB) is a chronic infectious disease mainly caused by Mycobacterium bovis. Although eradication is a priority for the European authorities, bTB remains active or even increasing in many countries, causing significant economic losses. The integral consideration of epidemiological factors is crucial to more cost-effectively allocate control measures. The aim of this study was to identify the nature and extent of the association between TB distribution and a list of potential risk factors regarding cattle, wild ungulates and environmental aspects in Ciudad Real, a Spanish province with one of the highest TB herd prevalences. Results: We used a Bayesian mixed effects multivariable logistic regression model to predict TB occurrence in either domestic or wild mammals per municipality in 2007 by using information from the previous year. The municipal TB distribution and endemicity was clustered in the western part of the region and clearly overlapped with the explanatory variables identified in the final model: (1) incident cattle farms, (2) number of years of veterinary inspection of big game hunting events, (3) prevalence in wild boar, (4) number of sampled cattle, (5) persistent bTB-infected cattle farms, (6) prevalence in red deer, (7) proportion of beef farms, and (8) farms devoted to bullfighting cattle. Conclusions: The combination of these eight variables in the final model highlights the importance of the persistence of the infection in the hosts, surveillance efforts and some cattle management choices in the circulation of M. bovis in the region. The spatial distribution of these variables, together with particular Mediterranean features that favour the wildlife-livestock interface may explain the M. bovis persistence in this region. Sanitary authorities should allocate efforts towards specific areas and epidemiological situations where the wildlife-livestock interface seems to critically hamper the definitive bTB eradication success

Como anécdota, se muestra cómo la eficiencia energética obtenida para las mismas cargas de trabajo en computadores personales es similar a la de algunos supercomputadores incluidos en el ranking Green500.Investigación financiada parcialmente por el Ministerio de Ciencia, Innovación y Universidades (MICIU) junto con el Fondo Europeo de Desarrollo Regional (FEDER), proyecto PGC2018-098813-B-C31

Evaluation of Three Methods for CPR Training to Lifeguards: A Randomised Trial Using Traditional Procedures and New Technologies

[EN] Background and objectives: When the drowning timeline evolves and drowning occurs, the lifeguard tries to mitigate the event by applying the last link of the drowning survival chain with the aim of treating hypoxia. Quality CPR (Cardiopulmonary Resuscitation) and the training of lifeguards are the fundamental axes of drowning survival. Mobile applications and other feedback methods have emerged as strong methods for the learning and training of basic CPR in the last years so, in this study, a randomised clinical trial has been carried out to compare the traditional method as the use of apps or manikins with a feedback system as a method of training to improve the quality of resuscitation. Materials and Methods: The traditional training (TT), mobile phone applications (AP) and feedback manikins (FT) are compared. The three cohorts were subsequently evaluated through a manikin providing feedback, and a data report on the quality of the manoeuvres was obtained. Results: Significant differences were found between the traditional manikin and the manikin with real-time feedback regarding the percentage of compressions with correct depth (30.8% (30.4) vs. 68.2% (32.6); p = 0.042). Hand positioning, percentage correct chest recoil and quality of compressions exceeded 70% of correct performance in all groups with better percentages in the FT (TT vs. FT; p < 0.05). Conclusions: As a conclusion, feedback manikins are better learning tools than traditional models and apps as regards training chest compression. Ventilation values are low in all groups, but improve with the feedback manikin.S
