La función de la evaluación docente dentro del sistema complejo de la educación en México

En este artículo se retoman aspectos que contextualizan la evaluación docente hacia la segunda década del siglo XX en México (en particular en el Estado de México) y se analiza este proceso como parte del sistema complejo de la educación. Se realizó un estudio documental de diferentes fuentes enfocadas a la teoría de sistemas de Niklas Luhman para entender al sistema de la educación como parte de los sistemas sociales; así como el proceso que ha tenido la evaluación de la educación, la postura del snte en la reconstrucción de este proceso y estadísticas de participación de los profesores en la evaluación docente. El análisis de la información recabada revela, por un lado, que la intención primordial de la evaluación docente es elevar la calidad de la educación en México; por otro lado, que tiene un alto impacto en los profesores con respecto a la certeza laboral; también se identificó que el SNTE participa activamente para informar y acompañar a sus agremiados en el complejo camino de la evaluación. En este estudio se plasma la necesidad de mejora en aspectos claves de la evaluación docente y se vislumbran otros que no se contemplaron en un inicio como medios de oportunidad para lograrlo; entonces se puede mencionar que la evaluación docente es un proceso necesario, sin embargo, falta puntualizar criterios de evaluación para cumplir con su intención. Este proceso a la fecha se encuentra inconcluso

Do Age, Gender and Poor Diet Influence the Higher Prevalence of Nomophobia among Young People?

We acknowledge the researchers of the research group AREA (HUM-672), which belongs to the Ministry of Education and Science of the Junta de Andalucía and is registered in the Department of Didactics and School Organization of the Faculty of Education Sciences of the University of Granada.The use of Information and Communication Technologies (ICT) is generating the emergence of new pathologies such as nomophobia. The aim of this research was to analyze the prevalence of nomophobia among young people, as well as to check whether the level of nomophobia is higher in males or females and in those students who claim to have less healthy nutrition due to the use of their mobile phones. The research method was based on a correlational and predictive design with a quantitative methodology. The measurement tool used is the Nomophobia Questionnaire (NMP-Q). The participating sample was 1743 students between 12 and 20 years old from different educational stages of the Autonomous City of Ceuta (Spain). The results show that highest rates of nomophobia were found in relation to the inability to communicate and contact others immediately. About gender, women have higher rates of nomophobia than men. In relation to age, no significant differences were found; thus, the problem may affect all ages equally. Finally, students who think that their smartphone use is detrimental to their good nutrition show higher levels on the scale provided.Corporacion Escuela Tecnologica del Oriente ISPRS-2017-7202Secretariat of Education of Santander ISPRS-2017-7202AreA HUM/672 Research Group of the University of Granada ISPRS-2017-720

A novel technique for sterilization using a power self-regulated single-mode microwave cavity

In this paper, a novel technique to achieve precise temperatures in food sterilization has been proposed. An accurate temperature profile is needed in order to reach a commitment between the total removal of pathogens inside the product and the preservation of nutritional and organoleptic characteristics. The minimal variation of the target temperature in the sample by means of a monitoring and control software platform, allowing temperature stabilization over 100 °C, is the main goal of this work. A cylindrical microwave oven, under pressure conditions and continuous control of the microwave supply power as function of the final temperature inside the sample, has been designed and developed with conditions of single-mode resonance. The uniform heating in the product is achieved by means of sample movement and the self-regulated power control using the measured temperature. Finally, for testing the sterilization of food with this technology, specific biological validation based on Bacillus cereus as a biosensor of heat inactivation has been incorporated as a distribution along the sample in the experimental process to measure the colony-forming units (CFUs) for different food samples (laboratory medium, soup, or fish-based animal by-products). The obtained results allow the validation of this new technology for food sterilization with precise control of the microwave system to ensure the uniform elimination of pathogens using high temperatures.This work was supported by the Ministerio de Economía y Competitividad under the project with reference DPI2014-61857-EXP

The Histone Chaperones SET/TAF-1β and NPM1 Exhibit Conserved Functionality in Nucleosome Remodeling and Histone Eviction in a Cytochrome c-Dependent Manner

Chromatin homeostasis mediates essential processes in eukaryotes, where histone chaperones have emerged as major regulatory factors during DNA replication, repair, and transcription. The dynamic nature of these processes, however, has severely impeded their characterization at the molecular level. Here, fluorescence optical tweezers are applied to follow histone chaperone dynamics in real time. The molecular action of SET/template-activating factor-Iβ and nucleophosmin 1—representing the two most common histone chaperone folds—are examined using both nucleosomes and isolated histones. It is shown that these chaperones present binding specificity for fully dismantled nucleosomes and are able to recognize and disrupt non-native histone-DNA interactions. Furthermore, the histone eviction process and its modulation by cytochrome c are scrutinized. This approach shows that despite the different structures of these chaperones, they present conserved modes of action mediating nucleosome remodeling.Ministerio de Educación y Cultura FPU016/01513European Commission PAIDI-DOCTOR 2020 DOC_00796European Molecular Biology Organization 8541European ARBRE-Mobieu consortium CA15126Ministerio de Ciencia e Innovación PGC 2018-096049-BI00, PID2021-126663NB-100Junta de Andalucía BIO198, US-1254317, P18-FR-3487, P18HO-409

Diseño e implementación de un modelo de mantenimiento preventivo para la empresa Mono Block S.A

En este manual de mantenimiento se comenta como se implementó el plan de mantenimiento preventivo. Inicialmente se recolectó la información técnica de los equipos, esto incluye marcas, modelos, números de serie, ubicación, capacidad, características eléctricas de los mismos, etc. Luego se codificaron los equipos de acuerdo a las áreas y al tipo de equipo ( neumático, eléctrico, mecánico, hidráulico, etc. ). Se determinó la criticidad de los equipos de acuerdo a su uso e importancia dentro de la empresa, estableciéndose tres criterios básicos, a saber: No critico ( edificios y equipos de oficina ), Normal ( equipos que pueden causar una parada de planta, pero que cuentan con respaldo ) y Critico ( equipos que pueden poner en riesgo la seguridad de las personas o del producto así como causar una parada de planta ya que no tienen respaldo )

Benefits of using conductive plastics in shielding configurations to reduce radiated electromagnetic interference

Conductive plastic cabinets have become an alternative to traditional metallic enclosures to shield electronic equipment from electromagnetic interference. These materials allow a wide range of conductivities that can satisfy any particular design. In this paper the benefits of using conductive plastics in enclosure configurations have been evaluated. A design with an outer metallic layer and an inner layer of conductive dielectric can provide advantages from both materials since a conductive plastic box is lighter and its shielding properties may have advantages over metallic materials. An optimum for resonance suppression has been obtained for the hybrid structure. These shielding structures have been evaluated with the help of measurements and simulations. Shielding effectiveness and Q-factor have been used to compare the capabilities of these enclosures with the metallic ones showing their benefits and possibilities. Resonance suppression and shielding levels provided by conductive plastics are discussed.This work was funded by Fundación Séneca, Agencia Regional de Ciencia y Tecnología, through the project 00700/PPC/04 and partly done during a research stay funded by the “Programa de formación y movilidad del personal docente e investigador de la Universidad Politécnica de Cartagena (PMPDI-UPCT-2007)” at the Physical Layer Group, Department of Electronics, University of York

The main objective of this research is to identify the effectiveness of the e-learning method in the teaching of mathematics with adults who are in high school, in contrast to the traditional expository method. The study developed is quantitative, descriptive and correlational. The research design is quasi-experimental, with a control group and an experimental group. The results show that the use of the e-learning method has a positive influence on motivation, autonomy, participation, mathematical concepts, results and grades. It can be concluded that the e-learning method leads to improvement in adult students who are studying the mathematical subject in the educational stage of high school, provided that it is compared with the expository method. Therefore, this method is considered effective for its implementation in adults.Corporacion Escuela Tecnologica del Oriente ISPRS-2017-720Secretariat of Education of Santander ISPRS-2017-7202AreA HUM/672 Research Group of the University of Granada ISPRS-2017-720

Fast computation of shielding effectiveness of metallic enclosures with apertures and inner elements

In this study, radiated immunity and emission of a metallic box with apertures have been evaluated through a fast approach. The influence of printed circuit boards inside the enclosure has been studied and also the effect of placing conductive polymer sheets in the housing in order to characterize the behaviour of these materials used nowadays for shielding cabinets. Measurements have been carried out in anechoic chamber in order to evaluate the approximated technique showing its limitations and advantages. Since good agreement has been found between simulations and measurements, this approach can be used for design or optimization purposes with the main advantage of reduced time calculations.This work has been funded by Fundación Séneca, Agencia Regional de Ciencia y Tecnología through the project 00700/PPC/04

Impact of the genetic improvement of fermenting yeasts on the organoleptic properties of beer

The brewing industry has experienced a significant boom in recent years through the emergence of, on the one hand, craft breweries that produce beers with unique organoleptic characteristics, and, on the other hand, the brewing of a significant number of beers using hybridized or genetically modified microorganisms with the aim of improving both the brewing processes and the final products. This review covers the influence from yeast strains on the organoleptic properties of the final beers and also the main hybridization and genetic modification methods applied to such yeast strains with the aim of improving the sensory characteristics of the product obtained and/or the brewing process. Different approaches to the phenotypic modification of the yeasts used in beer brewing have arisen in recent years. These are dealt with in this work, with special emphasis on the methodology followed as well as on the effects of the same on the brewing process and/or on the final produc
