Guía didáctica basada en recursos digitales para la enseñanza de las Leyes de Newton

The objective of this research is to analyze the relevance of the implementation of a teaching guide based on digital resources, for the improvement of the teaching-learning process of Newton's Laws in First Year Baccalaureate students, applied at Luis Cordero school, located in Azogues-Ecuador. It is a field investigation, it has a descriptive nature and a mixed approach. In the first instance, an analysis of learning difficulties is carried out, followed by a bibliographic review to design a strategy that helps improve learning results and evaluate the results derived from its application. The techniques used to collect data are: observation, documentary review, interview and survey. According to the results of the diagnosis, the relevance of the intervention proposal is analyzed to provide a solution to the identified problem. A pedagogical strategy is proposed to improve the teaching-learning process of Physics.  Esta investigación tiene como objetivo analizar la pertinencia de implementar una guía didáctica basada en recursos digitales, para el mejoramiento del proceso de enseñanza-aprendizaje de las Leyes de Newton en los estudiantes de Primero de Bachillerato, aplicada en la unidad Educativa Luis Cordero, ubicada en la ciudad de Azogues-Ecuador. La investigación es de campo, presenta carácter descriptivo y enfoque mixto. En primera instancia se realiza el análisis de las dificultades de aprendizaje, posterior a esto, una revisión bibliográfica para diseñar una estrategia que ayude a mejorar los resultados de aprendizaje y evaluar los resultados derivados de la aplicación de la misma. Las técnicas usadas para la recolección de los datos son: observación, revisión documental, entrevista y encuesta. Los resultados del diagnóstico llevaron a analizar la pertinencia de la propuesta de intervención para abordar la problemática identificada. Se propone una estrategia pedagógica para mejorar el proceso de enseñanza-aprendizaje de la Física

PERCEPCIONES DE LOS PROFESORES DE LA BENEMÉRITA UNIVERSIDAD AUTÓNOMA DE PUEBLA (BUAP) EN TORNO A LA DISPONIBILIDAD DE INFRAESTRUCTURA TECNOLÓGICA

This article has the aim to identify the perception of professors about the availability of technological infrastructure at BUAP. From a quantitative methodology that involved the application of a questionnaire to 71 professors, trough an exploratory factor analysis using the Statistical Package for the Social Sciences (SPSS version 15). Three factors explain the result. The first comprises the perception of network availability in the academic unit. The second refers to the perceived availability of hardware, and the last one is related to the perception of computers availability, showing that professors have a better perception of network availability respect to the other two factors. In addition, teachers in humanities' areas perceive a scarce availability of TIC. Also is evidenced that professors with part and full time at university have a better perception of availability of computers compared to professors that are hired per hour class. Thus, this configures a bias in the perceptions availability of technological infrastructure by university professors

Reducing the environmental impact of surgery on a global scale: systematic review and co-prioritization with healthcare workers in 132 countries

Abstract Background Healthcare cannot achieve net-zero carbon without addressing operating theatres. The aim of this study was to prioritize feasible interventions to reduce the environmental impact of operating theatres. Methods This study adopted a four-phase Delphi consensus co-prioritization methodology. In phase 1, a systematic review of published interventions and global consultation of perioperative healthcare professionals were used to longlist interventions. In phase 2, iterative thematic analysis consolidated comparable interventions into a shortlist. In phase 3, the shortlist was co-prioritized based on patient and clinician views on acceptability, feasibility, and safety. In phase 4, ranked lists of interventions were presented by their relevance to high-income countries and low–middle-income countries. Results In phase 1, 43 interventions were identified, which had low uptake in practice according to 3042 professionals globally. In phase 2, a shortlist of 15 intervention domains was generated. In phase 3, interventions were deemed acceptable for more than 90 per cent of patients except for reducing general anaesthesia (84 per cent) and re-sterilization of ‘single-use’ consumables (86 per cent). In phase 4, the top three shortlisted interventions for high-income countries were: introducing recycling; reducing use of anaesthetic gases; and appropriate clinical waste processing. In phase 4, the top three shortlisted interventions for low–middle-income countries were: introducing reusable surgical devices; reducing use of consumables; and reducing the use of general anaesthesia. Conclusion This is a step toward environmentally sustainable operating environments with actionable interventions applicable to both high– and low–middle–income countries

Diseño, producción e implementación de recursos educativos digitales en entornos de formación virtual

El desarrollo de este proyecto “diseño, producción e implementación de recursos educativos digitales en entornos de formación virtual” surgió de la necesidad de los docentes y/o estudiantes en medio de la situación actual COVID-19 aplicar diversos recursos educativos digitales en los entornos virtuales y en el desarrollo de sus clases en el proceso de enseñanza y aprendizaje del diplomado educación digital, en donde se generó la propuesta de diseñar, producir e implementar contenidos educativos digitales aprovechando el uso y la implementación de recursos visuales, audiovisuales, auditivos, interactivos y creativos para fortalecer el proceso de formación de los estudiantes a través de las diferentes herramientas implementadas en la plataforma MOODLE, en el marco de las competencias TIC para el desarrollo profesional del estudiante y docente orientado por el Ministerio de Educación Nacional, esto con el fin de incentivar a todos los actores involucrados en este proceso a la innovación, integración y exploración a través de las tecnologías de la información y la comunicación.CAPÍTULO 1 PROBLEMA EDUCATIVO 71.

CPW-Fed Transparent Antenna for Vehicle Communications

In this paper, a fully transparent multiband antenna for vehicle communications is designed, fabricated, and analyzed. The antenna is coplanar waveguide-fed to facilitate its manufacture and increase its transmittance. An indium-tin-oxide film, a type of transparent conducting oxide, is selected as the conductive material for the radiation path and ground plane, with 8 ohms/square sheet resistance. The substrate is glass with a relative permittivity of 5.5, and the overall dimensions of the optimized design are 50 mm × 17 mm × 1.1 mm. The main antenna parameters, namely, sheet resistance, reflection coefficient, and radiation diagram, were measured and compared with simulations. The proposed antenna fulfills the frequency requirements for vehicular communications according to the IEEE 802.11p standard. Additionally, it covers the frequency bands from 1.82 to 2.5 GHz for possible LTE communications applied to vehicular networks
