Cirugía de la mano reumática: nuevas expectativas para una vieja conocida
2017
ResumenEs importante que todos los especialistas que tratan a pacientes afectados de artritis reumatoide (AR), conozcan las distintas opciones terapéuticas disponibles, tanto médicas como quirúrgicas, y su manejo en las distintas fases del tratamiento. Nuestro objetivo es actualizar lo que como cirujanos debemos saber sobre el tratamiento médico de la enfermedad, cómo manejar los fármacos durante la programación de la cirugía y cuál es la evidencia sobre las distintas opciones quirúrgicas que podemos barajar ante diversas situaciones originadas por un aparente mismo patrón: la sinovitis.
Artroplastia de suspensión dinámica de Scheker en el tratamiento de la artrosis trapeciometacarpiana
2017
Objetivo Evaluar los resultados clínicos y radiográficos de una serie de pacientes sometidos a una artroplastia de Scheker. Material y Método Estudio descriptivo de 16 pacientes con artrosis TMC. Se valoró el estado clínico y funcional según el cuestionario DASH, la movilidad del pulgar según la escala de Kapandji y el dolor según la escala visual analógica (EVA). A nivel radiográfico, se cuantificó el colapso del espacio remanente tras la exéresis del trapecio. Resultados La edad promedio de los pacientes fue 64,9 años, 81% fueron mujeres. El tiempo de seguimiento medio fue de 19 meses. La puntuación DASH preoperatoria fue de 67,68 puntos y postoperatoria 34,88 (p < 0.001). La puntuaci…
Digital competence in teacher education: comparing national policies in Norway, Ireland and Spain
2021
This paper explores the development of policies dealing with teachers' digital competence in Norway, Ireland and Spain. Using a documentary research approach, the study analysed relevant policy documents from each country over a thirty-year period to the present day. Analysis of the documents highlights historical differences and similarities in how technology in education policies developed during that period and differences in how teacher education was addressed. Despite these differences, the analysis indicates a convergence in recent years towards a common understanding and the importance of teachers' digital competence influenced by supranational frameworks. The paper discusses the pot…
Diffusion of Drone Journalism: the Case of Finland, 2011-2020
2020
This article details Finnish news organizations’ adoption of drones for journalistic purposes from 2011 to 2020. The theoretical starting point of the article is Rogers’ (1962) diffusion of innovations theory, which explains how new ideas and technologies spread in societies. The main empirical data for the study were derived from a phone survey conducted among the 80 most popular newspapers in Finland. The findings reveal that drone journalism in Finland has already diffused from a few pioneering organizations to a large number of newsrooms, including regional, mid-sized newspapers. Most of the newspapers are either using in-house drones, buying commissioned images, or using both strategie…
Personalized multimedia touristic services for hybrid broadcast/broadband mobile receivers
2010
This paper presents the topology of a multimedia tourism service that targets mobile devices equipped with broadband and either multicast or broadcast access capabilities. Multicast / Broadcast access is used to handle the delivery of multimedia data to many simultaneous users in the service area. The solution adopted is based on existing standards for mobile TV services, but introducing features that enable the provision of generic multimedia services on top of mobile hybrid broadband and broadcast networks. Furthermore, this paper shows how to use standardized interfaces originally defined for interactive mobile TV broadcasting to build personalized mobile multimedia services that do not …
Cartoon filter via adaptive abstraction
2016
We propose a non-parametric methodology to realize abstraction images.The redundant wavelet "a trous" algorithm is applied for details detection.An multi-scale circular median filter is used as a smoothing filter.The proposed algorithm is simple and fast on low-cost entry-level hardware. Abstraction in computer graphics defines a procedure that discriminates the essential information that is worth keeping. Usually details, that correspond to higher frequency components, allow to distinguish otherwise similar images. Vice versa, low frequencies are related to the main information, which are larger structures. Contours themselves may also be identified by high frequencies and separate each pi…
Querytogether : Enabling entity-centric exploration in multi-device collaborative search
2018
Collaborative and co-located information access is becoming increasingly common. However, fairly little attention has been devoted to the design of ubiquitous computing approaches for spontaneous exploration of large information spaces enabling co-located collaboration. We investigate whether an entity-based user interface provides a solution to support co-located search on heterogeneous devices. We present the design and implementation of QueryTogether, a multi-device collaborative search tool through which entities such as people, documents, and keywords can be used to compose queries that can be shared to a public screen or specific users with easy touch enabled interaction. We conducted…
Perceptual similarity between color images using fuzzy metrics
2016
A method to measure the similarity between color images is proposed.Correlation among the color image channels is taken into account.Proposed similarity measure is based on fuzzy metrics because of their advantages.The proposal matches well with the perceptual visual similarity between color images. In many applications of the computer vision field measuring the similarity between (color) images is of paramount importance. However, the commonly used pixelwise similarity measures such as Mean Absolute Error, Peak Signal to Noise Ratio, Mean Squared Error or Normalized Color Difference do not match well with perceptual similarity. Recently, it has been proposed a method for gray-scale image s…
Reader Comments Agentive Power in COVID-19 Digital News Articles: Challenging Parascientific Information?
2022
The recent COVID-19 pandemic has triggered an enormous stream of information. Parascientific digital communication has pursued different avenues, from mainstream media news to social networking, at times combined. Likewise, citizens have developed new discourse practices, with readers as active participants who claim authority. Based on a corpus of 500 reader comments from The Guardian, we analyse how readers build their authorial voice on COVID-19 news as well as their agentive power and its implications. Methodologically, we draw upon stance markers, depersonalisation strategies, and heteroglossic markers, from the perspective of discursive interpersonality. Our findings unearth that stan…
An empirical evaluation of two natural hand interaction systems in augmented reality
2022
AbstractHuman-computer interaction based on hand gesture tracking is not uncommon in Augmented Reality. In fact, the most recent optical Augmented Reality devices include this type of natural interaction. However, due to hardware and system limitations, these devices, more often than not, settle for semi-natural interaction techniques, which may not always be appropriate for some of the tasks needed in Augmented Reality applications. For this reason, we compare two different optical Augmented Reality setups equipped with hand tracking. The first one is based on a Microsoft HoloLens (released in 2016) and the other one is based on a Magic Leap One (released more than two years later). Both d…
