Análisis de usabilidad del sistema de gestión de contenidos de la web de la Facultad

El objetivo de este proyecto es analizar desde el punto de vista de la usabilidad la herramienta “Sistema de gestión de contenidos” con el objetivo de proponer una serie de modificaciones y mejorar así la eficiencia de uso. Esta herramienta es utilizada por el personal de la Facultad para modificar y agregar nuevas páginas a la página Web de la Facultad. Para obtener la lista de cambios en primer lugar se plantea realizar una evaluación heurística donde se debe determinar los principios heurísticos a cumplir por la herramienta. Siguiendo estos principios se va a determinar una lista inicial de cambios y errores encontrados en el sistema la cual será refinada y actualizada a lo largo del proyecto según se vaya avanzando en el proyecto. A continuación se estudia a los usuarios para conocer sus características: conocimientos, tareas que realizan, cuándo usan la herramienta y bajo qué circunstancias. De esta manera, se puede amoldar la herramienta a las necesidades de los usuarios. Por último se estudian las tareas que realizan los usuarios y cómo las realizan siendo de gran importancia analizar porqué realizan las tareas de una determinada manera. Para cada error o fallo encontrado se va a determinar su prioridad de cambio y se va a indicar los hechos que provocan que se proponga un cambio para mejorarlo. No sólo se pretende determinar los errores sino también la mejor manera de solucionarlos. Para esto último es necesario por lo tanto conocer en profundidad a los usuarios de esta herramienta ya que son los grandes beneficiarios de este proyecto. A lo largo del proyecto se va a ir determinando el proceso a seguir para obtener los mejores resultados en el estudio. Este proceso incluye la creación de formularios que podrán ser utilizados en análisis de herramientas de características parecidas. Todos los formularios utilizados en el proyecto son de nueva creación y se explicará en cada caso las ideas en las que han basado para obtener el formulario final. Además se va a desarrollar un manual de usuario del sistema estudiado con el fin de que las personas que lean este proyecto se familiaricen con la herramienta que se evalúa. Este manual puede ser distribuido entre los nuevos usuarios de la herramienta ya que explica detenidamente su modo de funcionamiento. En conclusión, los principales objetivos de este proyecto son dos. En primer lugar obtener una lista ordenada por prioridad de cambios propuestos para la mejora de la herramienta desde el punto de vista de usabilidad estudiando a los usuarios y las tareas que realizan. En segundo lugar, determinar un proceso válido para analizar cualquier herramienta de características parecidas definiendo unos principios heurísticos así como una serie de formularios y cuestionarios. Un trabajo de este tipo es el que realizan las empresas especializadas en consultoría de usabilidad

Voronoi Diagram, Which health center is closest to me?

RESUMEN En este Trabajo de Fin de Máster se muestra la posibilidad de trabajar las matemáticas en contexto y conseguir que el alumnado se muestre activo, interesado y participativo en la asignatura de Matemáticas. En concreto, se ha trabajado el concepto de Diagrama de Voronoi, que consiste en realizar una partición del plano, delimitando las zonas más cercanas a cada conjunto de puntos. Concretamente, para que el alumnado pudiese conocer una aplicación de este en la vida real, se ha realizado el Diagrama de Voronoi de los Centros de Salud de la ciudad de Santander.ABSTRACT This Master Thesis shows the possibility of teaching Mathematics in a contextualized way, thus getting students to be more active, interested and participative in the Mathematics subject. Spicifically, the Voronoi Diagram has been taught for this research, which consists on the partition of a plane into regions close to each of a given set of objects. Concretely, for the students to know the application of this tool in real life, the Voronoi Diagram of the health centers of Santander has been carried out.Máster en Formación del Profesorado de Educación Secundari

Analysis of the carbide precipitation and microstructural evolution in HCCI as a function of the heating rate and destabilization temperature

Microstructural modifcation of high chromium cast irons (HCCI) through the precipitation of secondary carbides (SC) during destabilization treatments is essential for improving their tribological response. However, there is not a clear consensus about the frst stages of the SC precipitation and how both the heating rate (HR) and destabilization temperature can afect the nucleation and growth of SC. The present work shows the microstructural evolution, with a special focus on the SC precipitation, in a HCCI (26 wt% Cr) during heating up to 800, 900, and 980 °C. It was seen that the HR is the most dominant factor infuencing the SC precipitation as well as the matrix transformation in the studied experimental conditions. Finally, this work reports for frst time in a systematic manner, the precipitation of SC during heating of the HCCI, providing a further understanding on the early stages of the SC precipitation and the associated microstructural modifcations

Retrospective study of 149 cases of salivary gland carcinoma in a Spanish hospital population

The clinical and histological characteristics of salivary gland tumors vary widely, complicating their diagnosis and management, and major differences have been recorded in the distribution of histopathological diagnoses among different countries. This retrospective study reviewed the demographic (age, sex) and clinicopathological (pathology diagnosis and localization) characteristics of cases diagnosed with primary SGC between June 1992 and May 2014 in the Pathology Department of the 12 de Octubre Hospital of Madrid. Diagnoses were recorded according to the 2005 WHO classification. The study included 149 SCG patients, aged between 11 and 94 yrs, with mean age at onset of 55.56 yrs and peak incidence in the eighth decade of life. The male:female ratio was 1.01. The parotid gland was the most frequently involved (75.2%). The most frequent carcinoma was mucoepidermoid carcinoma (24.2%), followed by acinic cell carcinoma (15.4%). The demographic and histopathological characteristics of patients with salivary gland carcinomas in Spain, reported here for the first time, are broadly similar to those found in other countries

Methodologies for Fostering Critical Thinking Skills from University Students’ Points of View

Developing critical thinking skills appears to be a challenge for higher education institutions. However, little is known about the students’ points of view regarding the methodologies they consider to foster the development of this competence. To answer this question, a total of 263 Spanish university students participated in this study and were asked what they understood by critical thinking and the methodologies they considered to be the most effective for developing it. The results indicated that, based on students’ points of view, there were six methodologies that mainly contributed to developing critical thinking: Debates, project-based learning, practices in real contexts, doing research, cooperative learning, and case studies. These results were unanimous regardless of the student’s understanding of critical thinking: Analyzing/organizing, reasoning/arguing, questioning/asking oneself, evaluating, taking a position/taking a decision, compromising/acting. These findings have important theoretical and practical implications for teachers and educational institutions in relation to the development of critical thinking in higher education.The APC was funded by eDucaR research team through the University of Deusto/Basque Government Contract-Programme

A teachers’ based approach to assessing the perception of critical thinking in Education university students based on their age and gender

In the 21st century, critical thinking (CT) is regularly presented as one of the most important competences to be developed by a majority of educational institutions. Teachers are expected to change and enrich their teaching and learning methodologies so that students could face future challenges. Nonetheless, few are the instruments that measure the perception of critical thinking based on teachers’ conception. The aim of this study is to design and validate an instrument for the assessment of CT in university students based on the conception of CT that university teachers have. For this study, a total of 312 Spanish university students have participated. Based on a good model fit from a Confirmatory Factor Analysis and good reliability indices, the results provide strength to the theoretical model to evaluate critical thinking in university students formed by six dimensions (Analyzing/Organizing; Reasoning/Argumenting; Questioning/Asking oneself; Evaluating; Positioning /Taking decisions, and Acting /Committing oneself) and 42 items. Similarly, age was not a predictor variable for the different dimensions; while gender was statistically in favor of women in some of the dimensions, and tendentially, the dimension of Positioning/Taking decisions, in favor of men. However, despite these differences, the model guaranteed its factorial invariance. These findings have important pedagogical implications for universities in particular, and educational institutions in general, when developing curricula and teaching plans that focus on the development of students’ critical thinking.The publication has been funded by eDucaR research team through the University of Deusto/Basque Government Contract-Programme

A Detailed Analysis of the Microstructural Changes in the Vicinity of a Crack-Initiating Defect in Additively Manufactured AISI 316L

The fatigue life of metals manufactured via laser-based powder bed fusion (L-PBF) highly depends on process-induced defects. In this context, not only the size and geometry of the defect, but also the properties and the microstructure of the surrounding material volume must be considered. In the presented work, the microstructural changes in the vicinity of a crack-initiating defect in a fatigue specimen produced via L-PBF and made of AISI 316L were analyzed in detail. Xenon plasma focused ion beam (Xe-FIB) technique, scanning electron microscopy (SEM), and electron backscatter diffraction (EBSD) were used to investigate the phase distribution, local misorientations, and grain structure, including the crystallographic orientations. These analyses revealed a fine grain structure in the vicinity of the defect, which is arranged in accordance with the melt pool geometry. Besides pronounced cyclic plastic deformation, a deformation-induced transformation of the initial austenitic phase into α’-martensite was observed. The plastic deformation as well as the phase transformation were more pronounced near the border between the defect and the surrounding material volume. However, the extent of the plastic deformation and the deformation-induced phase transformation varies locally in this border region. Although a beneficial effect of certain grain orientations on the phase transformation and plastic deformability was observed, the microstructural changes found cannot solely be explained by the respective crystallographic orientation. These changes are assumed to further depend on the inhomogeneous distribution of the multiaxial stresses beneath the defect as well as the grain morphology
