Actions to be taken in Mexico towards education 4.0 and society 5.0

Education in Mexico has not evolved in the way it is taught and evaluated. In the historical moment that postmodernism enters, it has not been possible to adapt to Information and Communication Technologies(ICT), or rapid technological innovation, or changes and trends in the industry, to the sharing economy or the rise of distance races. In its analysis, an essential deficiency is detected in the current education models, and it is detected that educational freedom is nil or scarce, which has led to poor student performance, high youth unemployment, which cause severe social problems and the economy of the economy. The current government is working closely with the private sector to connect education and promote employment. It is necessary to grant public schools more autonomy, freedom and responsibility. This paper explains how to act so that Mexico can adapt education 4.0 with solid steps to reach society 5.0

Estrategias de fotorreticulación alternativas a la fotopolimerización de acrilatos para la preparación de materiales microestructurados de uso en aplicaciones biomédicas

El proyecto de la esta tesis doctoral se centra en el estudio de dos nuevas estrategias de fotopolimerización alternativas a la fotopolimerización radicalaria de acrilatos que permitan la preparación de materiales biocompatibles y microestructurados con potencial uso en aplicaciones biomédicas. Con este fin, se ha estudiado la posibilidad de reticular polímeros biodegradables mediante reacciones fotoinducidas en las que, por acción de la luz, se produzca una reacción entre dos grupos funcionales. De esta forma, partiendo de un polímero biodegradable con uno de los dos grupos funcionales y de un reticulante multifuncional de bajo peso molecular que contenga el otro grupo funcional, se puede generar una red polimérica que, tras ser degradada, va a generar únicamente fragmentos de bajo peso molecular. Esto representa una ventaja respecto a la tradicional estrategia de entrecruzamiento por fotopolimerización radicalaria de acrilatos, tradicionalmente usada en la generación de biomateriales, ya que esta reacción genera cadenas acrílicas no biodegradables que tienen un mayor riesgo de acumularse en el organismo y provocar una respuesta tóxica en el mismo. Las dos reacciones estudiadas son la descomposición fotoinducida de sales de diazonio y la química de tiol-inos. La primera está basada en la descomposición fotoinducida de los grupos diazonio aromáticos que generan una especia aromática capaz de reaccionar con grupos nucleófilos como los presentes en muchos polímeros naturales como diversos polisacáridos. Además esta reacción transcurre en disolución acuosa lo que representa una ventaja para este tipo de polímeros que pueden verse afectados por disolventes orgánicos. Respecto a la química de tiol-inos, resulta una manera eficiente de entrecruzar polímeros (tal y como se ha descrito en la bibliografía aunque no en la generación de biomateriales) y presentaría ciertas ventajas respecto a la química de tiol-enos, que ya se ha estudiado para esta aplicación. Entre estas ventajas cabe destacar la posibilidad de obtener redes con un mayor entrecruzamiento, lo cual puede ser ventajoso en algunas aplicaciones. Además, controlando la composición de la formulación fotopolimerizable y la presencia de grupos tiol o alquino sin reaccionar en el material entrecruzado, se podría llevar a cabo una funcionalización del material entrecruzado mediante reacción de los grupos alquino o tiol libres. Esto permitiría funcionalizar la superficie del material con biomoléculas que podrían inducir una determinada respuesta en las células cultivadas. En esta tesis doctoral se han utilizado estas dos reacciones para llevar a cabo el entrecruzamiento de polímeros naturales o sintéticos (en algunos casos modificados para introducir grupos fotorreactivos) y obtener de esta forma materiales biocompatibles. Estos materiales se procesaron en forma de película para ser utilizados como sustrato para el cultivo celular y estudiar así la biocompatibilidad de los mismos como andamiaje para las células. Por otro lado, se aplicaron también técnicas de escritura láser para generar patrones poliméricos en películas de preparadas para estas formulaciones. Estos patrones se generaron con distintos motivos o parámetros geométricos y fueron igualmente utilizados como sustrato para el cultivo celular. De esta forma se estudió como influyen algunos de estos parámetros en el comportamiento celular

Parenteral Nutrition: Current Use, Complications, and Nutrition Delivery in Critically Ill Patients

Complementary parenteral nutrition; Critically ill patients; Enteral nutritionNutrición parenteral complementaria; Pacientes críticamente enfermos; Nutrición enteralNutrició parenteral complementària; Pacients crítics; Nutrició enteralBackground: Parenteral nutrition (PN) is needed to avoid the development of malnutrition when enteral nutrition (EN) is not possible. Our main aim was to assess the current use, complications, and nutrition delivery associated with PN administration in adult critically ill patients, especially when used early and as the initial route. We also assessed the differences between patients who received only PN and those in whom EN was initiated after PN (PN-EN). Methods: A multicenter (n = 37) prospective observational study was performed. Patient clinical characteristics, outcomes, and nutrition-related variables were recorded. Statistical differences between subgroups were analyzed accordingly. Results: From the entire population (n = 629), 186 (29.6%) patients received PN as initial nutrition therapy. Of these, 74 patients (11.7%) also received EN during their ICU stay (i.e., PN-EN subgroup). PN was administered early (<48 h) in the majority of patients (75.3%; n = 140) and the mean caloric (19.94 ± 6.72 Kcal/kg/day) and protein (1.01 ± 0.41 g/kg/day) delivery was similar to other contemporary studies. PN showed similar nutritional delivery when compared with the enteral route. No significant complications were associated with the use of PN. Thirty-two patients (43.3%) presented with EN-related complications in the PN-EN subgroup but received a higher mean protein delivery (0.95 ± 0.43 vs 1.17 ± 0.36 g/kg/day; p = 0.03) compared with PN alone. Once adjusted for confounding factors, patients who received PN alone had a lower mean protein intake (hazard ratio (HR): 0.29; 95% confidence interval (CI): 0.18-0.47; p = 0.001), shorter ICU stay (HR: 0.96; 95% CI: 0.91-0.99; p = 0.008), and fewer days on mechanical ventilation (HR: 0.85; 95% CI: 0.81-0.89; p = 0.001) compared with the PN-EN subgroup. Conclusion: The parenteral route may be safe, even when administered early, and may provide adequate nutrition delivery. Additional EN, when possible, may optimize protein requirements, especially in more severe patients who received initial PN and are expected to have longer ICU stays.

Stimulus equivalence relations and equivalence-equivalence relations: effects of the training structure

En el presente estudio se investiga la influencia de la estructura de entrenamiento en la formación de relaciones de equivalencia y de “equivalencia-equivalencia”. Se estudiaron tres grupos de sujetos los cuales fueron entrenados con las estructuras: Muchos a Uno, Uno a Muchos o Serie Lineal para las relaciones condicionales. Se verificó el efecto de estructura de entrenamiento sobre la variable porcentaje de aciertos en el test de relaciones de equivalencia. Sin embargo, este fenómeno no se replicó en el test de relaciones de equivalencia-equivalencia. Los resultados indican que la estructura de entrenamiento influye cuando se forman relaciones de equivalencia, pero no cuando se forman relaciones de equivalencia-equivalencia. Se analizan los hallazgos considerando los requisitos para la formación de relaciones de equivalencia-equivalencia.The influence of training structure on the formation of equivalence relations and equivalence-equivalence relations was assessed. Three groups learned conditional relations using different training structures: Many to One, One to Many and Linear Series. The results showed a training structure effect on the percentage of correct responses in the equivalence relations test. However, this effect was not observed on the test of equivalence-equivalence relations. These results show that training structure has effects on the formation of equivalence relations, but it has no influence on equivalence-equivalence relations. These findings are analyzed according to the requirements for the formation of equivalence-equivalence relations.Fil: Fiorentini, Leticia. Consejo Nacional de Investigaciones Científicas y Técnicas.

Compactação do solo em sistemas de integração lavoura-pecuáriafloresta após cinco anos de implantação e uso

The objective of this work was to analyze the physical attributes of a Oxisol of different crop-livestock-forest integration systems implanted in 2012 and in use since then. The experimental design was a randomized complete block design, with four replications and four treatments: ILP - crop - livestock integration; ILPF 1L - agrosilvopastoral system, with one eucalyptus line; ILPF 3L - agrosilvopastoral system, with three eucalyptus lines; and EUC - exclusive plantation of eucalyptus (forest). From June 2017 to May 2018, mechanical penetration and gravimetric soil moisture evaluations were carried out to monitor soil compaction in three depths of soil: 0-0.05; 0.05-0.10 and 0.10-0.20 m. The results of the research show that there was a significant difference in the soil attributes studied, being the highest compaction found in the treatment ILPF 3L (0.05-0.10 m) near the limit considered ideal for a good development of the plants. Gravimetric soil moisture did not influence compaction results. In general, the results show that in the soil conditions of the region considered fragile and highly susceptible to compaction, the presence of the animals does not cause a very drastic compaction to the soil, with values lower than the critical limit of 2 MPa.O objetivo deste trabalho foi analisar os atributos físicos de um Latossolo Vermelho Amarelo de diferentes sistemas de integração lavoura-pecuária-floresta implantados em 2012 e em uso desde então. O delineamento experimental utilizado foi em blocos casualizados, com quatro repetições e quatro tratamentos: ILP - integração lavoura-pecuária; ILPF 1L - sistema agrossilvipastoril, com uma linha de eucalipto; ILPF 3L - sistema agrossilvipastoril, com três linhas de eucalipto; e EUC - plantio exclusivo de eucalipto (bosque). No período de junho de 2017 a maio de 2018 foram realizadas avaliações da resistência mecânica à penetração e da umidade gravimétrica do solo, a fim de monitorar a compactação, em três camadas do solo: 0-0,05; 0,05-0,10 e 0,10-0,20 m de profundidade. Os resultados mostram que houve diferença significativa para os atributos do solo estudados, sendo a maior compactação encontrada no tratamento ILPF 3L (0,05-0,10 m) próximo ao limite considerado ideal para um bom desenvolvimento das plantas. A umidade gravimétrica do solo não influenciou os resultados de compactação. De modo geral, os resultados mostram que a presença dos animais não causa uma compactação muito drástica ao solo, com valores menores que o limite crítico de 2 MPa
