Sistema de Comunicación Oral para Personas Sordas

Este artículo describe el desarrollo y la evaluación de un sistema de comunicación para personas sordas en un ámbito de aplicación específico: la renovación del permiso de conducir. El sistema de comunicación desarrollado está compuesto por dos módulos que permiten la comunicación en los dos sentidos. El primer módulo es un traductor de voz en castellano a Lengua de Signos Española (LSE) y está formado por un reconocedor de voz, un traductor de palabras en castellano a una secuencia de signos y un tercer módulo de representación de los signos mediante un agente animado. El segundo módulo es un generador de voz en castellano a partir de una secuencia de signos, y está formado por una interfaz donde se especifican los signos, un traductor (para convertir la secuencia de signos en una secuencia de palabras) y un conversor de texto a voz. En los dos módulos de traducción entre lenguas, se integran tres tecnologías: una basada en ejemplos, una basada en reglas y un traductor estadístico. Este artículo describe la evaluación del sistema llevada a cabo en la Jefatura Provincial de Tráfico de Toledo implicando a funcionarios de dicha jefatura y personas sordas

Language Resources for Spanish - Spanish Sign Language (LSE) translation

This paper describes the development of a Spanish Spanish Sign Language (LSE) translation system. Firstly, it describes the first Spanish Spanish Sign Language (LSE) parallel corpus focused on two specific domains: the renewal of the Identity Document and Driver’s License. This corpus includes more than 4,000 Spanish sentences (in these domains), their LSE translation and a video for each LSE sentence with the sign language representation. This corpus also contains more than 700 sign descriptions in several sign writing specifications. The translation system developed with this corpus consists of two modules: a Spanish into LSE translation module that is composed of a speech recognizer (for decoding the spoken utterance into a word sequence), a natural language translator (for converting a word sequence into a sequence of signs) and a 3D avatar animation module (for playing back the signs). The second module is a Spanish generator from LSE made up of a visual interface (for specifying a sequence of signs in sign writing), a language translator (for generating the sequence of words in Spanish) and a text to speech converter. For each language translation, the system uses three technologies: an example based strategy, a rule based translation method and a statistical translator

Ion Beam irradiation of copper nitride: electronic vs elastic-collision mechanism

Copper nitride is a metastable material which results very attractive because of their potential to be used in functional device. Cu3 N easily decomposes into Cu and N2 by annealing [1] or irradiation (electron, ions, laser) [2, 3]. Previous studies carried out in N-rich Cu3 N films irradiated with Cu at 42MeV evidence a very efficient sputtering of N whose yield (5×10 3 atom/ion), for a film with a thickness of just 100 nm, suggest that the origin of the sputtering has an electronic nature. This N depletion was observed to be responsible for new phase formation ( Cu2 O) and pure Cu [4

Significado psicológico de México entre niños

El objetivo del trabajo fue detectar el significado psicológico de "México" en niñas y niños. Se trabajó con 60 estudiantes de Primaria, repartidos equitativamente por género, con edades entre nueve y once años. Se utilizó la técnica original de redes semánticas naturales para obtener la información referente al significado psicológico de México. Las aplicaciones se hicieron de forma grupal en los salones de clase. Los resultados dejan ver que entre los participantes hubo una definición muy favorable de México, en la que los niños orientaron sus respuestas hacia los aspectos políticos, en comparación con las niñas, que definieron a México con base en sus bellezas naturales y las características afectivas de sus habitantes. Se observó que prevalece una tendencia instrumental en el género masculino, en contraste con la de tipo afectivo y expresivo del género femenino, rasgos propios de la cultura mexicana desde mucho tiempo atrás, que al parecer no registran cambios trascendentales en los papeles o roles asignados para cada uno de los géneros en México

Examinig the mediating role of coping and emotion regularion in stress models in adolescents

The aim of this research was to analyze the relationship between stressful events, coping, and emotion regulation in adolescents from marginalized settings. A cross-sectional study was conducted with 523 adolescents aged 13 to 15 years. The Global Scale of Perceived Stress for Adolescents, the Coping Scale for Adolescents, and the Multidimensional Scale of Emotion Regulation for Adolescents, were used. Several mediation models were tested considering whether coping mediated the relationship between stressful events and emotion regulation responses, or, on contrary, emotion regulation assumes a mediating role between stressful events and coping. Data indicate significant direct and indirect effects in all models, with the highest explained variance in the models which included emotion regulation as a mediating variable. Results are discussed considering the role of coping and emotion regulation as mediating variables, and their relationship with diverse stressful events. In this research, emotion regulation strategies lead to adolescent coping

Monitoring and Prognosis System Based on the ICF for People with Traumatic Brain Injury

The objective of this research is to provide a standardized platform to monitor and predict indicators of people with traumatic brain injury using the International Classification of Functioning, Disability and Health, and analyze its potential benefits for people with disabilities, health centers and administrations. We developed a platform that allows automatic standardization and automatic graphical representations of indicators of the status of individuals and populations. We used data from 730 people with acquired brain injury performing periodic comprehensive evaluations in the years 2006-2013. Health professionals noted that the use of color-coded graphical representation is useful for quickly diagnose failures, limitations or restrictions in rehabilitation. The prognosis System achieves 41% of accuracy and sensitivity in the prediction of emotional functions, and 48% of accuracy and sensitivity in the prediction of executive functions. This monitoring and prognosis system has the potential to: (1) save costs and time, (2) provide more information to make decisions, (3) promote interoperability, (4) facilitate joint decision-making, and (5) improve policies of socioeconomic evaluation of the burden of disease. Professionals found the monitoring system useful because it generates a more comprehensive understanding of health oriented to the profile of the patients, instead of their diseases and injuries

An accessible deep learning tool for voxel-wise classification of brain malignancies from perfusion MRI

Deep learning; Glioblastoma; Perfusion MRIAprenentatge profund; Glioblastoma; Ressonància magnètica de perfusióAprendizaje profundo; Glioblastoma; Resonancia magnética de perfusiónNoninvasive differential diagnosis of brain tumors is currently based on the assessment of magnetic resonance imaging (MRI) coupled with dynamic susceptibility contrast (DSC). However, a definitive diagnosis often requires neurosurgical interventions that compromise patients' quality of life. We apply deep learning on DSC images from histology-confirmed patients with glioblastoma, metastasis, or lymphoma. The convolutional neural network trained on ∼50,000 voxels from 40 patients provides intratumor probability maps that yield clinical-grade diagnosis. Performance is tested in 400 additional cases and an external validation cohort of 128 patients. The tool reaches a three-way accuracy of 0.78, superior to the conventional MRI metrics cerebral blood volume (0.55) and percentage of signal recovery (0.59), showing high value as a support diagnostic tool. Our open-access software, Diagnosis In Susceptibility Contrast Enhancing Regions for Neuro-oncology (DISCERN), demonstrates its potential in aiding medical decisions for brain tumor diagnosis using standard-of-care MRI.This project was supported by “La Caixa” Foundation (RTI2018-095209-B-C21) and the Spanish Ministry of Science and Innovation (FIS-G64384969).

Utility of MF-non coding region for measles molecular surveillance during post-elimination phase, Spain, 2017-2020

Background: In countries entering the post-elimination phase for measles, the study of variants by sequencing of 450 nucleotides of the N gene (N450) does not always allow the tracing of chains of transmission. Indeed, between 2017 and 2020, most measles virus sequences belonged to either the MVs/Dublin.IRL/8.16 (B3-Dublin) or the MVs/Gir Somnath.IND/42.16 (D8-Gir Somnath) variants. We evaluated the additional use of a non-coding region (MF-NCR) as a tool to enhance resolution and infer case origin, chains of transmission and characterize outbreaks. Methods: We obtained 115 high-quality MF-NCR sequences from strains collected from Spanish patients infected with either B3-Dublin or D8-Gir Somnath variants between 2017 and 2020, performed epidemiological, phylogenetic and phylodynamic analyses and applied a mathematical model to determine relatedness among identified clades. Results: Applying this model allowed us to identify phylogenetic clades potentially derived from concomitant importations of the virus rather than single chain of transmission, inferred based on only N450 and epidemiology data. In a third outbreak, we found two related clades that corresponded to two chains of transmission. Discussion: Our results show the ability of the proposed method to improve identification of simultaneous importations in the same region which could trigger enhanced contact tracing. Moreover, the identification of further transmission chains indicates that the size of import-related outbreaks was smaller than previously found, supporting the interpretation that endemic measles transmission was absent in Spain between 2017 and 2020. We suggest considering the use of the MF-NCR region in conjunction with the study of N450 variants in future WHO recommendations for measles surveillance.This work was supported by the “Instituto de Salud Carlos III” (PI15CIII/00023, PI19ICIII/0041).

Identification of novel targets in adipose tissue involved in non-alcoholic fatty liver disease progression

Obesity is a major risk factor for the development of Nonalcoholic fatty liver disease (NAFLD). We hypothesize that a dysfunctional subcutaneous white adipose tissue (scWAT) may lead to an accumulation of ectopic fat in the liver. Our aim was to investigate the molecular mechanisms involved in the causative role of scWAT in NALFD progression. We performed a RNA-sequencing analysis in a discovery cohort (n = 45) to identify genes in scWAT correlated with fatty liver index, a qualitative marker of liver steatosis. We then validated those targets in a second cohort (n = 47) of obese patients who had liver biopsies available. Finally, we obtained scWAT mesenchymal stem cells (MSCs) from 13 obese patients at different stages of NAFLD and established in vitro models of human MSC (hMSC)-derived adipocytes. We observed impaired adipogenesis in hMSC-derived adipocytes as liver steatosis increased, suggesting that an impaired adipogenic capacity is a critical event in the development of NAFLD. Four genes showed a differential expression pattern in both scWAT and hMSC-derived adipocytes, where their expression paralleled steatosis degree: SOCS3, DUSP1, SIK1, and GADD45B. We propose these genes as key players in NAFLD progression. They could eventually constitute potential new targets for future therapies against liver steatosis
