Factores de riesgo en pacientes con intento suicida ingresados en el Hospital Psicosocial Abril 2017-Diciembre 2018

Con el objetivo de establecer los factores de riesgo en paciente que ingresan en la Unidad de Intervención en Crisis del Hospital Psicosocial por intento suicida en el período de Abril 2017 a Diciembre 2018, se realizó un estudio descriptivo, correlacional y analítico. Fueron analizados los datos sobre las características sociodemográficas, y la clasificación de la escala de riesgo suicida de SAD PERSONS, con el fin de conocer el riesgo suicida en los pacientes. Los análisis estadísticos efectuados fueron: descriptivos, pruebas de Correlación Paramétrica de Pearson. Del análisis y discusión de los resultados obtenidos, se alcanzaron las siguientes conclusiones: El sexo femenino fue el de mayor predominio con un 74% , las edad más frecuente fue de 19 años con una frecuencia de 22 casos significando el 12% , presentaron estado civil acompañado en un 38.5%, el 38.5% eran católicos, el 55% estaban desempleados, el 62% habían realizado intento suicida previo, el 55% presentaban síntomas depresivos al ingreso, el 12% presentaron como factor desencadenante conflictos de pareja, el método más frecuente para realizar intento suicida fue la intoxicación farmacológica en un 46% de casos. La prueba de correlación de Pearson demostró una correlación significativa de: depresión (p=0.407), psicosis (p=0.252), desempleo (p=0.236), con el riesgo suicida encontrado al momento del ingreso hospitalario. Durante la evaluación de un paciente que realiza intento suicida, se debe utilizar como algoritmo de síntesis de información la escala de evaluación suicida de SAD PERSONS, y considerar variables en nuestro contexto como el estado civil acompañado

Double equity in court decisions in the Plata Viceroyalty during the late eighteenth century

The purpose of this article is to discuss the issue of motivation of court decisions in the Plata Viceroyalty during the eighteenth century. We aim to establish a discussion with the current historiographical debate and then to analyze the philosophical basis of court decisions, showing that in many of them it was common to resort to double equity.A finalidade deste artigo é a de discutir o tema da motivação das sentenças judiciais no Vice-reinado do Prata no século XVIII.

A comprehensive survey on recent deep learning-based methods applied to surgical data

Minimally invasive surgery is highly operator dependant with a lengthy procedural time causing fatigue to surgeon and risks to patients such as injury to organs, infection, bleeding, and complications of anesthesia. To mitigate such risks, real-time systems are desired to be developed that can provide intra-operative guidance to surgeons. For example, an automated system for tool localization, tool (or tissue) tracking, and depth estimation can enable a clear understanding of surgical scenes preventing miscalculations during surgical procedures. In this work, we present a systematic review of recent machine learning-based approaches including surgical tool localization, segmentation, tracking, and 3D scene perception. Furthermore, we provide a detailed overview of publicly available benchmark datasets widely used for surgical navigation tasks. While recent deep learning architectures have shown promising results, there are still several open research problems such as a lack of annotated datasets, the presence of artifacts in surgical scenes, and non-textured surfaces that hinder 3D reconstruction of the anatomical structures. Based on our comprehensive review, we present a discussion on current gaps and needed steps to improve the adaptation of technology in surgery.Comment: This paper is to be submitted to International journal of computer visio

Combining safety and speed in collaborative assembly systems – An approach to time optimal trajectories for collaborative robots

Abstract Human-robot interaction is a key enabling technology of Industry 4.0 and the prospected pervasiveness of robotics in industrial environments will be not possible without enabling them to safety interact with humans. Such a fact imposes a relevant constraints because the limits imposed by the actual technical deliverables entail strong requirements in the operational velocity of robots when sharing their workspace with humans. In this paper, we address the theoretical limits of velocity under the light of current state-of-the-art trajectory planning and normative requirements. The main goal is to find a methodology to plan safe trajectories without neglecting cognitive ergonomics and production efficiency aspects. We start by considering the set of trajectories which are optimal with respect to a cognitive criteria and give a suitable parametrization to it. Then we are able to formulate the safety requirements in terms of constraints in an optimization problem. Finally, experimental results are provided. This allow the identification of the preferable sets of possible motions which satisfy the operator psychological wellbeing and the assembly process performance by complying the safety requirements in terms of mechanical risk prevention

Cartography of memory. Aby Warburg and the Atlas Mnemosyne

[EN] In 1905, Aby Warburg, a german art historian of Jewish origin interested in western classical culture proposes a heuristic research method on memory and images. Holder of a huge image catalogue, Warburg devises a procedure to investigate and represent unobvious relations system trough collage and montage: the Bilderatlas Mnemosyne. Process allows replacing of images or introducing new elements to establish new relationship, an open & infinite procedure that creates a personal cartography thus making possible new constant rereading. Barely developed due to his premature death, Aby Warburg¿s lessons permeate all the coming visual culture.[ES] En 1905 Aby Warburg, un historiador del Arte alemán de origen judío interesado en la cultura clásica occidental propone un método de investigación heurística sobre la memoria y las imágenes. Poseedor de un ingente catálogo de imágenes, Warburg idea un procedimiento de exploración y presentación de sistemas de relaciones no evidentes mediante técnicas de collage y montaje: el Bilderatlas Mnemosyne. El proceso permite el reposicionamiento de imágenes o la introducción parcial de nuevos elementos, para establecer nuevas relaciones, un proceso abierto e infinito que crea una cartografía personal posibilitando constantes relecturas. Apenas desarrolladas por su temprana muerte, las lecciones de Aby Warburg impregnan toda la cultura visual venidera.Tartás Ruiz, C.; Guridi Garcia, R. (2013). Cartografías de la memoria.

SUPRA: Superpixel Guided Loss for Improved Multi-modal Segmentation in Endoscopy

Domain shift is a well-known problem in the medical imaging community. In particular, for endoscopic image analysis where the data can have different modalities the performance of deep learning (DL) methods gets adversely affected. In other words, methods developed on one modality cannot be used for a different modality. However, in real clinical settings, endoscopists switch between modalities for better mucosal visualisation. In this paper, we explore the domain generalisation technique to enable DL methods to be used in such scenarios. To this extend, we propose to use super pixels generated with Simple Linear Iterative Clustering (SLIC) which we refer to as "SUPRA" for SUPeRpixel Augmented method. SUPRA first generates a preliminary segmentation mask making use of our new loss "SLICLoss" that encourages both an accurate and color-consistent segmentation. We demonstrate that SLICLoss when combined with Binary Cross Entropy loss (BCE) can improve the model's generalisability with data that presents significant domain shift. We validate this novel compound loss on a vanilla U-Net using the EndoUDA dataset, which contains images for Barret's Esophagus and polyps from two modalities. We show that our method yields an improvement of nearly 20% in the target domain set compared to the baseline.Comment: This work has been accepted at the LatinX in Computer Vision Research Workshop at CVPR 202

Lineamientos para el diseño de muros estructurales irregulares de concreto armado según la NTE E -060

El presente informe de tesis fue una investigación de tipo exploratoria, donde se realizó el estudio de 3 muros de concreto armado: un muro regular, un muro irregular tipo L y uno muro irregular tipo C, analizando 3 viviendas multifamiliares, que oscilan entre los entre los 6 y 9 niveles, diseñando cada uno de los elementos que forman los muros estudiados, con el objetivo de obtener criterios y lineamientos mínimos para el diseño de muros irregulares de concreto armado. Para ello, se usó el programa estructural de edificaciones Etabs 2019, con el cual modelamos las estructuras y verificamos que los resultados del análisis estructural, sísmico estático, sísmico dinámico y modal, cumplan con lo establecido en nuestro RNE, verificando que la relación Demanda – Capacidad fue menor a 1 en cada muro a Flexocompresión y por Cortante - Capacidad. Adicionalmente a esto, se diseñó los elementos de borde, puesto que su correcto confinamiento, otorgó mayor ductilidad al muro. También usamos el programa Sap 2000 para hallar la profundidad de compresión de la fibra más traccionada al eje neutro, haciendo una comparación de este resultado con el que nos ofrece el método simplificado que propuso años atrás el Dr Jack Moehle. Esta comparación tuvo un asertividad del 80% entre estas dos metodologías. Después detallamos el armado del acero de refuerzo de cada muro, e hicimos una comparativa entre la distribución de acero de refuerzo según nuestra normar NTE E.060 y el ACI 318.14, donde se verificó que actualmente no contamos con una adecuada norma para confinar los bordes de los muros de concreto armado. Finalmente propusimos los pasos a seguir para el correcto análisis, diseño y armado de los muros estructurales estudiados, dentro de los cuales concluimos que se debe confinar los elementos de borde con el Código ACI 318, hasta que nuestra norma E.060 tenga una correcta actualización.The present thesis report was an exploratory research, carried out the study of 3 reinforced concrete walls: a regular wall, an irregular wall type L and an irregular wall type C, analyzing 3 multi-family dwellings, which range between 6 and 9 levels, designing each one of the elements that form the walls studied, with the aim of obtaining criteria and minimum guidelines for their design For this, the Etabs 2019 building structural program was used, with which we modeled the structures and verified that the results of the structural, static seismic, dynamic seismic and modal analysis, comply with what is established in our RNE, verifying that the Demand - Capacity was less than 1 in each wall at Flexocompression and Shear - Capacity. In addition to this, the edge elements were opened, since their correct confinement gave the wall greater ductility. We use the Sap 2000 program to find the compression depth of the fiber with the most traction to the neutral axis, comparing this result with the one offered by the simplified method, which ten years ago Dr Jack Moehle, this comparison had an assertiveness of 80% between these two methodologies. Then we detailed the reinforcing steel reinforcement of each wall, and made a comparison between the distribution of reinforcing steel according to our NTE E.060 standard and ACI 318.14, where it was verified that we currently do not have an adequate standard to confine the edges. of reinforced concrete walls. Finally, we proposed the steps to follow for the correct analysis, design and assembly of the structural walls studied, within which we concluded that the edge elements must be confined with the ACI 318 Code, until our E.060 standard has a correct updateTesi

a human in the loop cyber physical system for collaborative assembly in smart manufacturing

Abstract Industry 4.0 rose with the introduction of cyber-physical systems (CPS) and Internet of things (IoT) inside manufacturing systems. CPS represent self-controlled physical processes, having tight networking capabilities and efficient interfaces for human interaction. The interactive dimension of CPS reaches its maximum when defined in terms of natural human-machine interfaces (NHMI), i.e., those reducing the technological barriers required for the interaction. This paper presents a NHMI bringing the human decision-making capabilities inside the cybernetic control loop of a smart manufacturing assembly system. The interface allows to control, coordinate and cooperate with an industrial cobot during the task execution
