    El presente libro contiene doce reflexiones que nos sugieren un balance para repensar la educaci√≥n superior tras las experiencias pand√©micas en tres dimensiones: pedagog√≠a, did√°ctica general y did√°cticas especiales, Estas tres dimensiones ofrecen un panorama integral para repensar los problemas educativos actuales. A diferencia de otros balances que hemos visto o le√≠do en los √ļltimos a√Īos, el presente se compone de tres ejes que atraviesan todas las reflexiones: reorganizaci√≥n de ideas, consolidaci√≥n de la inter y transdisciplina, y mejora efectiva de las pr√°cticas de ense√Īanza-aprendizaje desde planes y programas de estudios hasta actividades entre docentes y alumnos.Coordinadoras: Alma Elisa Delgado Coellar, Juana Cecilia Angeles Ca√Īedo & Daniela Vel√°zquez Ru√≠

    The evolution of the ventilatory ratio is a prognostic factor in mechanically ventilated COVID-19 ARDS patients

    Background: Mortality due to COVID-19 is high, especially in patients requiring mechanical ventilation. The purpose of the study is to investigate associations between mortality and variables measured during the first three days of mechanical ventilation in patients with COVID-19 intubated at ICU admission. Methods: Multicenter, observational, cohort study includes consecutive patients with COVID-19 admitted to 44 Spanish ICUs between February 25 and July 31, 2020, who required intubation at ICU admission and mechanical ventilation for more than three days. We collected demographic and clinical data prior to admission; information about clinical evolution at days 1 and 3 of mechanical ventilation; and outcomes. Results: Of the 2,095 patients with COVID-19 admitted to the ICU, 1,118 (53.3%) were intubated at day 1 and remained under mechanical ventilation at day three. From days 1 to 3, PaO2/FiO2 increased from 115.6 [80.0-171.2] to 180.0 [135.4-227.9] mmHg and the ventilatory ratio from 1.73 [1.33-2.25] to 1.96 [1.61-2.40]. In-hospital mortality was 38.7%. A higher increase between ICU admission and day 3 in the ventilatory ratio (OR 1.04 [CI 1.01-1.07], p = 0.030) and creatinine levels (OR 1.05 [CI 1.01-1.09], p = 0.005) and a lower increase in platelet counts (OR 0.96 [CI 0.93-1.00], p = 0.037) were independently associated with a higher risk of death. No association between mortality and the PaO2/FiO2 variation was observed (OR 0.99 [CI 0.95 to 1.02], p = 0.47). Conclusions: Higher ventilatory ratio and its increase at day 3 is associated with mortality in patients with COVID-19 receiving mechanical ventilation at ICU admission. No association was found in the PaO2/FiO2 variation

    Investigación Lógica Borrosa para la Evaluación de la Sostenibilidad

    No full text
    En la evaluación de la sostenibilidad se tiene en cuenta el impacto que cualquier actuación produce en factores sociales, culturales, económicos y medioambientales. Este trabajo presenta el desarrollo de una metodología y un software usando lógica borrosa para la evaluación de la sostenibilidad social, económica y medioambiental de proyectos para llegar a conseguir una evaluación global de la sostenibilidad.The measure of sustainability takes into account the impact that social, economic and environmental factors can produce. This job presents the development of a methodology and software using fuzzy logic for the evaluation of social, economic and environmental sustainability of projects to pretend to come by a global sustainability evaluation

    Partial orderings for hesitant fuzzy sets

    Get PDF
    New partial orderings =o=o, =p=p and =H=H are defined, studied and compared on the set HH of finite subsets of the unit interval with special emphasis on the last one. Since comparing two sets of the same cardinality is a simple issue, the idea for comparing two sets A and B of different cardinalities n and m respectively using =H=H is repeating their elements in order to obtain two series with the same length. If lcm(n,m)lcm(n,m) is the least common multiple of n and m we can repeat every element of A lcm(n,m)/mlcm(n,m)/m times and every element of B lcm(n,m)/nlcm(n,m)/n times to obtain such series and compare them (Definition 2.2). (H,=H)(H,=H) is a bounded partially ordered set but not a lattice. Nevertheless, it will be shown that some interesting subsets of (H,=H)(H,=H) have a lattice structure. Moreover in the set BB of finite bags or multisets (i.e. allowing repetition of objects) of the unit interval a preorder =B=B can be defined in a similar way as =H=H in HH and considering the quotient set View the MathML sourceB¬Ņ=B/~ of BB by the equivalence relation ~ defined by A~BA~B when A=BBA=BB and B=BAB=BA, View the MathML source(B¬Ņ,=B) is a lattice and (H,=H)(H,=H) can be naturally embedded into it.Peer ReviewedPostprint (author's final draft
