Pseudoaneurysms in Peripheral Vasculature Following a Percutaneous Intervention, Different Diagnostic Approaches: Case Reports

Pseudoaneurysm is defined as a vascular anomaly generated by the interruption of the arterial wall, which conditions accumulation and persistent confinement of blood. The incidence of pseudoaneurysm ranges between 0.2%-0.5% in diagnostic interventional techniques and up to 6% in therapeutic techniques, however, despite its low incidence, complications are potentially severe. We present 3 cases of pseudoaneurysm in the peripheral vasculature after percutaneous interventions, as well as the description of the diagnostic challenge and the assessment by the different imaging methods. This case report article shows the diagnostic approach through the different imaging methods, as well as a brief review of the subject with a focus on the role of the interventional radiologist

Speech Prosody

An automatic labeling system using Sp ToBI annotation conventions has been applied both to a non-native corpus of Japanese speakers using Spanish and to a reference corpus of Spanish speakers. A set of metrics based on conditional entropy is computed by using the output of an automatic labeler which happens to be highly correlated with the rates assigned by a team of subject evaluators. An analysis of the relative frequencies in the use of each of the Sp ToBI symbols permits to identify the recurrent mistakes in the productions of non-native speakers. It is discussed with the results that the majority of the observed prosodic deficits can be explained by the prosodic transference between the Japanese and Spanish systems as it had been previouly reported in the state of art.MEC-FEDER Grant TIN2014-59852-R y la Junta de Castilla y León Regional Grant VA145U1

Automatic assessment of non-native prosody by measuring distances on prosodic label sequences

The aim of this paper is to investigate how automatic prosodic labeling systems contribute to the evaluation of non-native pronunciation. In particular, it examines the efficiency of a group of metrics to evaluate the prosodic competence of non-native speakers, based on the information provided by sequences of labels in the analysis of both native and non-native speech. A group of Sp ToBI labels were obtained by means of an automatic labeling system for the speech of native and non-native speakers who read the same texts. The metrics assessed the differences in the prosodic labels for both speech samples. The results showed the efficiency of the metrics to set apart both groups of speakers. Furthermore, they exhibited how nonnative speakers (American and Japanese speakers) improved their Spanish productions after doing a set of listening and repeating activities. Finally, this study also shows that the results provided by the metrics are correlated with the scores given by human evaluators on the productions of the different speaker

Engaging adolescents with Down syndrome in an educational video game

Producción CientíficaThis article describes the design, implementation and evaluation of an educational video game that helps individuals with Down syndrome to improve their speech skills, specifically those related to prosody. Special attention has been paid to the design of the user interface, taking into account the cognitive, learning, and attentional limitations of people with Down syndrome. The learning content is conveyed by activities of production and perception of prosodic phenomena, aimed at increasing their communicative competence. These activities are introduced within the narrative of a video game so that the players do not conceive the tool as a mere succession of learning activities, but so that they learn and improve their speech while playing. The evaluation strategy that has been followed involves real users and combines different evaluation activities. Results show a high level of acceptance by participants and also by professionals, speech therapists, and special education teachers.2018-09-01MEC-FEDER Grant TIN2014-59852-R y la Junta de Castilla y León Regional Grant VA145U1

La piedra mágica : un videojuego educativo orientado a la mejora de las habilidades comunicativas orales como ventana a la inclusión social

"La piedra mágica" es, un videojuego que se ha diseñado como herramienta educativa dirigida al alumnado con Necesidades Específicas de Apoyo Educativo y, en particular, a personas con síndrome de Down. Pretende incrementar las habilidades comunicativas de estas personas a través de una mejora de su prosodia (entonación, fluidez, entre otras propiedades) y, consecuentemente, favorecer su inclusión social y laboral. Una de las principales novedades de "La piedra mágica" es su diseño interdisciplinar, ya que en este proyecto hemos colaborado lingüistas, psicolingüistas, ingenieros informáticos, pedagogos y filósofos para conseguir un entorno educativo complejo y adaptable. Es una herramienta que puede ser empleada de manera autónoma o supervisada y que almacena un historial de seguimiento de cada jugador, de manera que los profesionales pueden acceder a los datos de cada alumno y observar su desarrollo fomentando aquellas carencias más destacadas en cada perfil. Uno de los aspectos más originales de la herramienta es que el jugador se comunica con el resto de personajes del videojuego con su propia voz, lo que le motiva y ayuda a mejorar su capacidad comunicativa. Tras realizar una primera prueba piloto se ha comprobado que más del sesenta por ciento de los alumnos ganan naturalidad y fluidez en su elocución"La piedra mágica" is a video-play designed as an educational tool for students with special needs, including children with Down syndrome. It is aimed at enhancing communication skills by improving prosody (fluency, tone, etc.), which leads to social and vocational inclusion. It has been created by the interdisciplinary collaboration of people specialized in linguistics and psycholinguistics, informatic engineers, educators and philosopher

Applying a fuzzy classifier to generate Sp ToBI annotation : preliminar results

One of the goals of the Glissando research project1 is to enrich a radio news corpus [1] with Sp ToBI labels. In this paper we present the application of the automatic predictions of a fuzzy classifier to speed up the labeling process. The strategy is proposed after completing the following steps: a) manual annotation of a part of the Glissando corpus with Sp ToBI labels and checking of the coherence of the labels; b) training of the automatic system; c) validation or correction of the automatic system's predictions by a human expert. The automatic judgments of the classifier are enriched with confidence measures that are useful to represent uncertain situations concerning the label to be assigned. The main aim of the paper is to show that there exists a correspondence between the uncertain situations that are identified during an inter-transcriber experiment and the uncertain situations that the fuzzy classifier detects. Labeling time reduction encourages the use of this strateg

Dinámica y perspectiva de la Cooperación Triangular en la República de El Salvador. Casos de estudio: triangulaciones entre El Salvador-España y El Salvador-Chile. Periodo 2013-2015.

Como un importante hallazgo en la investigación, de acuerdo al Capítulo I, se destaca que la Cooperación Triangular es complementaria a la CSS. Por otro lado, la CTr es construida desde la práctica, con ello se dificulta establecer parámetros concretos, sin embargo, se llevan a cabo esfuerzos para definir actuaciones.En el Capítulo II se resalta el marco normativo e institucional de la CTr, en función de la gestión de dicha modalidad de cooperación en El Salvador, haciendoénfasis en la profesionalización del Viceministerio de Cooperación Internacional para el Desarrollo, sus actuaciones y principales socios cooperantes.En el capítulo III la investigación concluye con dos estudios de casos emblemáticos para la CTr, en la que participa El Salvador como socio primer oferente de la cooperación. Ello posiciona al país como un cooperante emergente en la región iberoamericana, basando su actuación en instrumentos jurídicos, negociación diplomática y lecciones aprendidas.Todo lo anteriormente expresado se sustenta académicamente en la teoría de los sistemas políticos de David Easton, principalmente y se acompaña de elementos teóricos de autores como Karl Deutch y Herbert Spiro
