Entorno de realidad virtual controlado en tiempo real por señales motoras para la rehabilitación del miembro superior en pacientes con daño cerebral

Este trabajo tiene como meta el desarrollo de un sistema de neurorrehabilitación mediante realidad virtual para pacientes con problemas motores en las extremidades superiores provocados por un daño cerebral. Para entender y enfrentarse de manera correcta al problema, se han revisado todos los aspectos concernientes al daño cerebral y déficits motores derivados así como las terapias empleadas para su rehabilitación, como las que utilizan tecnologías asistidas como la realidad virtual. Se han expuesto las ventajas que han llevado a utilizar esta terapia en el proyecto y se han mencionado algunos estudios de investigación previos y con resultados favorables. Por último, se ha hecho hincapié en las novedades (embodiment y neuronas espejo) que aporta este proyecto con las que se podría acelerar la rehabilitación de los pacientes incidiendo en la plasticidad cerebral. En lo que se refiere al desarrollo del entorno, se ha utilizado el motor de videojuegos Unity 3D, con el que se ha integrado el dispositivo Myo Armband, para capturar el movimiento, y las gafas de realidad virtual Oculus Rift DK2. Durante la terapia, el paciente tiene que superar una serie de niveles definidos por el terapeuta y, para ello, debe realizar un alcance y tocar un botón un número de veces por cada nivel. En cada nivel, el esfuerzo que tiene que realizar el paciente es distinto, dependiendo de la distancia a la que se encuentre el botón (relativa al calibrado previo del paciente) e igualmente, está definido por el terapeuta. También se lleva a cabo un registro de las aceleraciones y del porcentaje de acierto del paciente en un fichero, para llevar un control de su progreso. Como conclusión, cabe mencionar que el entorno desarrollado es adaptable a las posibilidades de cada paciente, permitiendo una recuperación óptima. Se trata de un sistema de bajo coste, intuitivo y que lleva a cabo un registro de datos de la actividad del paciente, lo que posibilita, como trabajo futuro, el control de forma remota por parte del terapeuta. Todos estos aspectos dejan abierta la posibilidad de que el paciente lo utilice a domicilio, con las ventajas que conlleva. Del mismo modo, el sistema se podría adaptar fácilmente para la rehabilitación de las extremidades inferiores. Tras su análisis, los investigadores expertos en la materia del Consejo Superior de Investigaciones Científicas afirman que el sistema satisface con creces su propósito. Con todo esto, se concluye que este entorno tiene un excelente presente y un futuro muy prometedor

Status and distribution of Paraguayan macaws (Aves: Psittacidae) with a new country record

Eight species of macaw (Psittacidae: Anodorhynchus, Ara, Primolius) have previously been reported from Paraguay. We discuss all verifiable reports of the species from Paraguay and provide comment on their statuses. Ara chloropterus and Primolius auricollis are both widespread species known from multiple reports across a wide geographic area. We report minor range extensions within Paraguay for both species. Anodorhynchus hyacinthinus is documented as a breeding resident with a restricted distribution in the Upper Paraguay River basin. The first modern records of Ara ararauna and the first record of Diopsittaca nobilis for the country are documented with photographs. We are unable to find any confirmed records of Anodorhynchus glaucus from Paraguay and thus consider it of possible occurrence. Two species are rejected as erroneously cited, Ara militaris and Ara glaucogularis. Consequently six species in four genera are now confirmed to occur in Paraguay

Cardiovascular Health of the Balearic Islands (Spain) After the COVID-19 Pandemic

[eng] Background/Objectives: The COVID-19 pandemic caused healthcare managers to reallocate resources from other areas in order to handle the outbreak. Cardiovascular usual care was especially affected during the first wave. Methods: We analyzed the short- and mid-term impact of the resource reallocation on cardiovascular health, focusing on the Balearic Islands in Spain. Data from 2019 to 2021 of the regional healthcare system and from the national and regional stats center were collected in order to analyze the variations in type of admissions, main causes of cardiovascular mortality, and the correlation between the monthly variation in those causes of mortality and total cardiovascular mortality. Results: The year 2021 showed worse results in terms of healthcare outcomes compared to the pre-pandemic period, with a population-adjusted cardiovascular mortality increase of 4.8% and heart failure and hypertension being the main drivers (6.4% and 26.45%, respectively). However, this impact was not homogeneous in both pandemic years. In 2020, the main driver for the cardiovascular mortality increase was myocardial infarction (R Pearson = 0.655/p = 0.021). On the other hand, chronic conditions such as heart failure and hypertension led to the increase in cardiovascular mortality in 2021 (R Pearson = 0.671/p = 0.017 and R Pearson = 0.619/p = 0.032, respectively). In-hospital resources for COVID-19 showed a positive correlation to cardiovascular mortality in 2021; however, it did not reach statistical significance (R Pearson = 0.41/p = 0.1). Conclusions: Mid-term cardiovascular health worsened in the Spanish Balearic Island region, with hypertension and heart failure being the main drivers, with important differences in influence between 2020 and 2021. We found a correlation between COVID-19 in-hospital resource allocation and total cardiovascular mortality

Strategies of the Teaching Process - Learning and Academic Performance in University Teaching Students in a Public University in Lima

The objective of this study was to determine the relationship between the strategies of the teaching-learning process and the performance of University Teaching students, in a public university in Lima. The research is descriptive, and the design is non-experimental. Two instruments were used: the Checklist and the Standardized Test for a sample that consisted of 15 students of the Master's Degree in University Teaching, who attended the academic semester 2009 - I of the National University of Education "Enrique Guzmán y Valle -La Cantuta. According to the general hypothesis, it was concluded that there is a relationship between strategies of the teaching-learning process and the academic performance of Master's degree students, University Teaching mention. Regarding the specific hypotheses, it was concluded that the level of correlation that exists between the strategies of the teaching-learning process and the conceptual, procedural and attitudinal academic performance of the students in question is highly significant

The innocence in Réquiem por un campesino español by Ramón J. Sender

Este artículo analiza la novela Réquiem por un campesino español (1953), de Ramón J. Sender, a la luz del concepto de inocencia, proveniente de los postulados filosóficos de Sören Kierkegaard y Paul Ricoeur. El objetivo es revisar las diferentes connotaciones de este concepto en la novela para demostrar que se configura como un complejo entramado simbólico representativo del conflicto ideológico entre los personajes principales, y que, a su vez, dicho conflicto, implica al lector. La disertación presenta las nociones teóricas que definen la inocencia para analizar algunas síntesis premonitorias de la trama que la toman en cuenta. Después se analizan acciones y símbolos clave que implican a la inocencia en la vida de Paco el del Molino y el papel de Mosén Millán ante ello. Finalmente, se plantea la lucha simbólica entre el bien y el mal que refleja el estado de inocencia en el lector.This article analyzes the novel Réquiem por un campesino español (1953) by Ramón J. Sender, in the light of the concept of innocence, derived from the philosophical postulates of Sören Kierkegaard and Paul Ricoeur. The objective is to observe the different connotations of this concept in the novel to prove that it is configured as a complex symbolic network representing the ideological conflict between the main characters, and that, in turn, said conflict involves the reader. The dissertation presents the theoretical notions that define innocence to analyze some premonitory syntheses of the plot that involves it. Afterwards, key actions and symbols that imply innocence in the life of Paco el del Molino and the position taken by Mosén Millán are analyzed. Finally, the symbolic fight between good and evil is presented, which reflects the state of innocence in the reader

First record of the globally-threatened Cerrado endemic snake <i>Philodryas livida</i> (Amaral, 1923) (Serpentes, Dipsadidae) from Paraguay, and the importance of the Reserva Natural Laguna Blanca to its conservation

Paraguay. Reserva Natural Laguna Blanca (RNLB), Departamento San Pedro. (23º46’52.6”S, 56º17’28.9”W). RNLB is a 804 hectare reserve consisting of over 400 hectares of near pristine Cerrado, a patch of degraded Atlantic Forest, and areas of transitional semi-deciduous, semi-humid gallery forest. The four main Cerrado ecotopes are present at RNLB and grow on a predominately sandy substrate (Eiten, 1972; 1978). The reserve is based around an eponymously-named freshwater lake of 157 hectares which, geologically-speaking, is possibly the only true lake in Paraguay (Guyra Paraguay, 2008).Asociación Herpetológica Argentina (AHA
