Radiotórax.es: una herramienta para la evaluación on-line de las capacidades interpretativas en radiografía de tórax.

Introducción La radiografía de tórax es una de las técnicas diagnósticas más importantes ya que aporta gran cantidad de información para el diagnóstico de enfermedades respiratorias y cardíacas. Es la prueba radiológica más usada en urgencias, ampliamente utilizada por especialistas de radiología, por médicos de familia y otras especialidades (intensivistas, neumólogos, anestesistas, internistas, pediatras y cardiólogos). Su correcta interpretación es fundamental, pues con frecuencia influye en la toma de decisión para el manejo del paciente. La autoevaluación, metodología poco explorada en nuestro entorno, es una parte del proceso educativo que fomenta la reflexión sobre las competencias adquiridas del individuo en formación, donde el alumno se evalúa para progresar en su formación y no para superar una nota, eliminar una materia o establecer un orden de prelación con sus compañeros. Justificación y objetivos Los objetivos de este trabajo son: 1) desarrollar una aplicación informática que permita autoevaluar las habilidades interpretativas de la radiografía de tórax emulando una sesión de trabajo de 20 casos; 2) evaluar el funcionamiento e introducir mejoras en fases preliminares, y 3) analizar los hábitos de uso y las posibilidades formativas de la misma. Material y métodos Radiotórax.es es una herramienta Web de libre acceso por toda la comunidad, ubicada en la URL www.radiotorax.es. El sistema pretende emular una sesión de trabajo, informando 20 casos radiológicos , seleccionados aleatoriamente de una base de datos de 400, con una o dos proyecciones de tórax que debe informar disponiendo de una hora. Los informes y resultados se archivan en una base de datos y el usuario dispone de un documento pdf detallado de cada ronda de evaluación que realice. Resultados Se analizan los resultados del global de usuarios registrados en la fase beta de desarrollo de la aplicación ( 30/05/2011 - 31/08/2011) y durante el período comprendido entre el 01/09/2011 hasta el 31/12/2013 de la fase definitiva de la aplicación, que sigue vigente en la actualidad. La autoevaluación en Radiotorax.es guarda correlación con el grado de experiencia y nivel de aprendizaje del usuario, obteniéndose mejores resultados los grupos con mayor experiencia y formación. Además el 75.7% de los usuarios mejoró en evaluaciones sucesivas.

Descreve-se, no presente trabalho, os esforços envidados no sentido de criar uma solução informática generalista, para os problemas mais recorrentes do processo de produção de videojogos 20, baseados em sprites, a correr em plataformas móveis. O sistema desenvolvido é uma aplicação web que está inserida no paradigma cloud­computing, usufruindo, portanto, de todas as vantagens em termos de acessibilidade, segurança da informação e manutenção que este paradigma oferece actualmente. Além das questões funcionais, a aplicação é ainda explorada do ponto de vista da arquitetura da implementação, com vista a garantir um sistema com implementação escalável, adaptável e de fácil manutenção. Propõe-se ainda um algoritmo que foi desenvolvido para resolver o problema de obter uma distribuição espacial otimizada de várias áreas retangulares, sem sobreposições nem restrições a nível das dimensões, quer do arranjo final, quer das áreas arranjadas. ABSTRACT: This document describes the efforts taken to create a generic computing solution for the most recurrent problems found in the production of two dimensional, sprite­based videogames, running on mobile platforms. The developed system is a web application that fits within the scope of the recent cloud-computing paradigm and, therefore, enjoys all of its advantages in terms of data safety, accessibility and application maintainability. In addition, to the functional issues, the system is also studied in terms of its internal software architecture, since it was planned and implemented in the perspective of attaining an easy to maintain application, that is both scalable and adaptable. Furthermore, it is also proposed an algorithm that aims to find an optimized solution to the space distribution problem of several rectangular areas, with no overlapping and no dimensinal restrictions, neither on the final arrangement nor on the arranged areas.

Off-line and On-line Affective Recognition of a Computer User through A Biosignal Processing Approach

Physiological signals, which are controlled by the autonomic nervous system (ANS), could be used to detect the affective state of computer users and therefore find applications in medicine and engineering. The Pupil Diameter (PD) seems to provide a strong indication of the affective state, as found by previous research, but it has not been investigated fully yet. In this study, new approaches based on monitoring and processing the PD signal for off-line and on-line affective assessment (“relaxation” vs. “stress”) are proposed. Wavelet denoising and Kalman filtering methods are first used to remove abrupt changes in the raw Pupil Diameter (PD) signal. Then three features (PDmean, PDmax and PDWalsh) are extracted from the preprocessed PD signal for the affective state classification. In order to select more relevant and reliable physiological data for further analysis, two types of data selection methods are applied, which are based on the paired t-test and subject self-evaluation, respectively. In addition, five different kinds of the classifiers are implemented on the selected data, which achieve average accuracies up to 86.43% and 87.20%, respectively. Finally, the receiver operating characteristic (ROC) curve is utilized to investigate the discriminating potential of each individual feature by evaluation of the area under the ROC curve, which reaches values above 0.90. For the on-line affective assessment, a hard threshold is implemented first in order to remove the eye blinks from the PD signal and then a moving average window is utilized to obtain the representative value PDr for every one-second time interval of PD. There are three main steps for the on-line affective assessment algorithm, which are preparation, feature-based decision voting and affective determination. The final results show that the accuracies are 72.30% and 73.55% for the data subsets, which were respectively chosen using two types of data selection methods (paired t-test and subject self-evaluation). In order to further analyze the efficiency of affective recognition through the PD signal, the Galvanic Skin Response (GSR) was also monitored and processed. The highest affective assessment classification rate obtained from GSR processing is only 63.57% (based on the off-line processing algorithm). The overall results confirm that the PD signal should be considered as one of the most powerful physiological signals to involve in future automated real-time affective recognition systems, especially for detecting the “relaxation” vs. “stress” states.

ESEV TV is available to all study cycles from the institution where it is allocated and represents a workshop camp where it is possible to practice techniques and develop knowledge in the television production area. The accomplishment of the project purpose is inextricably dependent on the existence of a working group constantly updated, also multidisciplinary, that aggregates students from different areas. This complex interdependent mission is guided by teachers with knowledge and experience in the audiovisual field. The team work expects to produce an interesting online schedule that reunites, at the same time, information, culture, education and entertainment.

The Effect of Level Testosteron e Addition in Diluents and Level Dilution on Speed Movement and Abnormality of Kedu Chicken Sperm

The research entitled “The Effect of Level Testosterone Addition in Diluents and Level Dilution on Speed Movement and Abnormality of Kedu Chicken Sperm” was conducted in Laboratory of Physiology and Reproduction, Faculty of Animal Science, UNSOED, started at August 15th to September 15th , 2001. The aims of  this research were to obtain influences of level testosterone and dilution on speed movement and secondary abnormality kedu chicken sperm and obtain interaction between the treatments. The tapped sperm from nine kedu chickens were used in this research. This Experiment was performed 4 x 3 Factorials with Randomized  Completely Block Design (RCBD) as the basic design. The treatment combinations were level testosterone 0, 300, 600 and 900 μg (t0, t1, t2 and t3) and level of dilution 4, 6 and 8 time (in a row p1, p2 and p3). The tapping period was replicated four times as a group (replicated) with two days interval. The result of this research showed that the interaction between level of testosterone addition and level of dilution gave a non-significant effect to speed movement sperm but significant to abnormality of kedu chicken sperm. The group gave a significant influence (P<0.05) to speed movement sperm and non significant to sperm abnormality. The interaction of level testosterone addition and level dilution of kedu chicken semen (T x P) has a quadratic regression to sperm abnormality with regression comparison is Y = 24.418 – 0.014 X +1.187E – 05 X², with peak point is (543.76: 20.23) of correlation coefficient (r) 0.55 and determination coefficient (R²) as 30.34%. The addition of 600 μg testosterone level with 6 level dilutions was the best to defend sperm abnormality.

Human muscle spindles act as forward sensory models.

Modern theories of motor control incorporate forward models that combine sensory information and motor commands to predict future sensory states. Such models circumvent unavoidable neural delays associated with on-line feedback control. Here we show that signals in human muscle spindle afferents during unconstrained wrist and finger movements predict future kinematic states of their parent muscle. Specifically, we show that the discharges of type Ia afferents are best correlated with the velocity of length changes in their parent muscles approximately 100-160 ms in the future and that their discharges vary depending on motor sequences in a way that cannot be explained by the state of their parent muscle alone. We therefore conclude that muscle spindles can act as "forward sensory models": they are affected both by the current state of their parent muscle and by efferent (fusimotor) control, and their discharges represent future kinematic states. If this conjecture is correct, then sensorimotor learning implies learning how to control not only the skeletal muscles but also the fusimotor system.
