Digital dictionary of sign language Argentina : fourth part

En el presente período proponemos "Diccionario Digital de Lengua de Señas Argentina - 4º parte" (2019/20) con el objeto de finalizar un trabajo que ha generado un desarrollo teórico y un corpus lingüístico que valida y resguarda a la LSA como patrimonio cultural de la Comunidad Sorda.El equipamiento de un espacio específico para realizar la tarea, alcanzada en el proyecto anterior, permite generar las condiciones para poder volver a realizar las filmaciones detectadas por los expertos, durante el período de investigación anterior, que consideraron de baja calidad. Por ello, nos proponemos cumplir con esta tarea y validar el resultado final con la Comunidad Sorda. Tanto las personas Sordas como las oyentes consideran que esta es una herramienta útil en el acercamiento y aprendizaje de la Lengua de Señas en su estado natural, sin la intervención ni la influencia de otra lengua. Esto hace que la propuesta resulte innovadora en el ámbito de estudio de la Lengua de Señas Argentina, en las dimensiones no sólo léxicas sino de estudio fonológico, discursivo y pragmático.La continuidad del proyecto evidencia la importancia y la complejidad del estudio de una lengua viso-espacial, propia de una comunidad lingüística minoritaria y con requerimientos de análisis específicos y diversos a los existentes en las lenguas fónicas.In this period we propose "Digital Dictionary of Sign Language Argentina - 4th part" (2019/20) with the aim of finalizing a work that has generated a theoretical development and a linguistic corpus that validates and protects the LSA as a cultural heritage of the Deaf Community.The equipping of a specific space to carry out the task, achieved in the previous project, allows generating the conditions to be able to re-perform the filming detected by the experts, during the previous research period, which they considered to be of low quality. Therefore, we intend to fulfill this task and validate the final result with the Deaf Community.Both Deaf people and listeners consider that this is a useful tool in the approach and learning of Sign Language in its natural state, without the intervention or the influence of another language. This makes the proposal innovative in the field of study of the Sign Language Argentina, in the not only lexical dimensions but also phonological, discursive and pragmatic study.The continuity of the project demonstrates the importance and complexity of the study of a viso-spatial language, typical of a linguistic minority community and with specific analysis requirements and diverse to those existing in phonic languages

A security metric for assessing the security level of critical infrastructures

The deep integration between the cyber and physical domains in complex systems make very challenging the security evaluation process, as security itself is more of a concept (i.e. a subjective property) than a quantifiable characteristic. Traditional security assessing mostly relies on the personal skills of security experts, often based on best practices and personal experience. The present work is aimed at defining a security metric allowing evaluators to assess the security level of complex Cyber-Physical Systems (CPSs), as Critical Infrastructures, in a holistic, consistent and repeatable way. To achieve this result, the mathematical framework provided by the Open Source Security Testing Methodology Manual (OSSTMM) is used as the backbone of the new security metric, since it allows to provide security indicators capturing, in a non-biased way, the security level of a system. Several concepts, as component Lifecycle, Vulnerability criticality and Damage Potential – Effort Ratio are embedded in the new security metric framework, developed in the scope of the H2020 project ATENA

Control architecture to provide E2E security in interconnected systems: the (new) SHIELD approach

Modern Systems are usually obtained as incremental composition of proper (smaller and SMART) subsystems interacting through communication interfaces. Such flexible architecture allows the pervasive provisioning of a wide class of services, ranging from multimedia contents delivery, through monitoring data collection, to command and control functionalities. All these services requires that the adequate level of robustness and security is assured at End-to- End (E2E) level, according to user requirements that may vary depending on the specific context or the involved technologies. A flexible methodology to dynamically control the security level of the service being offered is then needed. In this perspective, the authors propose an innovative control architecture able to assure E2E security potentially in any application, by dynamically adapting to the underlying systems and using its resources to “build the security”. In particular, the main novelties of this solution are: i) the possibility of dynamically discovering and composing the available functionalities offered by the environment to satisfy the security needs and ii) the possibility of modelling and measuring the security through innovative technology-independent metrics. The results presented in this paper moves from the solutions identified in the pSHIELD project and enrich them with the innovative advances achieved through the nSHIELD research, still ongoing. Both projects have been funded by ARTEMIS-JU

Piezoelectric Nanofibers for Integration in Multifunctional Materials

This paper deals with realization of multifunctional composite materials, having piezoelectric effect. First of all polymeric mats of electrospun piezoelectric nanofibers were realized with different geometries. Such effect has been maximized by designing properly the electrospinning apparatus in order to enhance the electric field in the interelectrodic space which polarize the dipolar moments. The mats are then integrated in a silicon rubber matrix and measurements of the electromechanical response of the composite materials thus manufactured are performed. A good integration of nanofibers inside the host material is evidenced by electron microscopy images, allowing delaminations, which could occur using piezoelectric films, to be avoided. A large electrical response to both impact and vibration stimuli has been finally demonstrated

LENGUA DE SEÑAS ARGENTINA EN LA COMUNIDAD SORDA DE MENDOZA: CARACTERÍSTICAS DISTINTIVAS DEL EVENTO CONVERSACIONAL

Este artículo desarrolla aspectos claves de un proyecto de investigación llevado a cabo por un grupo de docentes investigadores de la Facultad de Educación de la Universidad Nacional de Cuyo. Su propósito es describir aspectos propios de la conversación en Lengua de Señas Argentina – LSA – entre hablantes Sordos de la provincia de Mendoza, Argentina y, por otro lado, responder a la necesidad de elaborar material teórico específico para la Tecnicatura en Interpretación de Lengua de Señas Argentina. Para ello, en primer lugar, se recopiló el material teórico existente que describe diversos aspectos conversacionales de las lenguas fónicas y de la LSA, luego, se obtuvieron muestras videograbadas de conversaciones entre personas Sordas, hablantes fluidas de LSA, de la comunidad mendocina y, por último, se analizaron dichas muestras a la luz de los postulados teóricos y se elaboraron las conclusiones pertinentes. De este modo, la metodología utilizada respondió a un enfoque cualitativo, con un diseño descriptivoexploratorio. Las técnicas de recolección de datos utilizadas fueron la observación participante y la filmación, las cuales, luego, se transcribieron a glosas, permitiendo la triangulación y el análisis de las muestras. Finalmente, no solo nos fue posible identificar algunos elementos pragmáticos presentes en los intercambios desarrollados en la lengua implicada, sino que, además, tuvimos la oportunidad de transcribir muestras conversacionales que denotan con claridad el modo en que estas sucedieron, empleando los signos que otros lingüistas aplican en los estudios formales de las lenguas fónicas

B-TURP versus HoLEP. Peri-operative outcomes and complications in frail elderly (>75 y.o.) patients. A prospective randomized study

Background: The aim of this study was to compare the peri-operative and functional results between trans-urethral resection of the prostate (TURP) and holmium laser enucleation of the prostate (HoLEP) in the treatment of benign prostatic hyperplasia (BPH) associated with lower urinary tract symptoms (LUTS) in middle-old patients. Materials and methods: This prospective single-center study included patients over 75 years old treated with B-TURP or HoLEP for BPH associated with LUTS with prostate volume (PV) <100 mL. Primary endpoints were the intra-operative blood loss, percentage of loss of hemoglobin, blood transfusion, complications, and the comparison of functional outcomes. All patients were evaluated at 1, 3, 6, and 12 months of follow-up. Results: Overall, 96 patients undergoing HoLEP and 104 B-TURP were eligible and enrolled for the study. Post-operative results showed statistically significant differences between the two groups, all in favor of HoLEP group, specifically in terms of removed prostate tissue, PV reduction rate, hemoglobin values at 24 h, hemoglobin loss, operative time, length of hospitalization, days of catheterization, and urinary flow rates. There was no significant difference in terms of postvoid residual urine volume, perioperative complication, blood transfusion, International Prostate Symptom Score (IPSS), and IPSS quality of life scores. Conclusions: In middle-old patients, the HoLEP technique represents a prostate size-independent treatment option with a more favorable safety profile defined by less bleeding, lower blood transfusions, and a significantly lower hemoglobin drop than B-TURP
