    El objetivo general del presente trabajo de suficiencia profesional es demostrar que se ha alcanzado las competencias profesionales del psicólogo organizacional, a través de la elaboración de un plan de trabajo para mejorar el bienestar psicológico de un trabajador que se desempeña en la modalidad de teletrabajo en una entidad del estado. Se utilizó la metodología de estudio de caso, donde la participante es una mujer que desempeña el cargo de Especialista administrativo. El estudio para el diagnóstico situacional de la variable bienestar psicológico fue mediante el uso de tres instrumentos: Escala de Bienestar Psicológico de Ryff, una entrevista semi estructurada y un cuestionario online. Los resultados indicaron un bienestar psicológico de nivel moderado; con una autovaloración que refleja un gozo moderado de la vida, caracterizado por una condición mental regular, por la presencia de ciertas emociones negativas. En cuanto a las dimensiones de bienestar psicológico, la mayoría de éstas se encuentran en un nivel medio, mientras que la dimensión Relaciones Positivas en un nivel Bajo. Por ello, se diseñó un plan de intervención en búsqueda de mejorar el Bienestar Psicológico; éste se elaboró con base en el coaching y el modelo Grow de Whitmore (2011), el cual busca gestionar un cambio y crecimiento a nivel personal y profesional, orientado al establecimiento de metas. Como resultado, se espera mejoras en los indicadores del bienestar psicológico, con mayor atención en la dimensión relaciones positivas, los mismos que volverán a ser evaluados a través de La Escala de Bienestar Psicológico de Ryff.The general objective of the present work of professional sufficiency is to demonstrate that the professional competences of the organizational psychologist have been reached, through the elaboration of a work plan to improve the psychological well-being of a worker who works in the modality of telework in an entity of the government. The methodology of case study was used, where the participant is a woman who holds the position of administrative specialist. The study for the situational diagnosis of the variable psychological well-being was through the use of three instruments: Ryff's Psychological Well-Being Scale, a semi-structured interview and an online questionnaire. The results indicated a moderate level of psychological well-being; with a self assessment reflecting a moderate enjoyment of life, characterized by a regular mental condition, by the presence of certain negative emotions. As for the dimensions of psychological well-being, most of them are at a medium level, while the dimension Positive Relationships is at a Low level. Therefore, an intervention plan was designed in search of improving Psychological Well-being; it was elaborated based on coaching and Whitmore's Grow model (2011), which seeks to manage change and growth at a personal and professional level, oriented to the establishment of goals. As a result, improvements are expected in the indicators of psychological well-being, with greater attention to the positive relationships dimension, which will be re-evaluated through Ryff's Psychological Well-Being Scale

    Las nuevas técnicas de imagen de alta resolución (TAC multicorte, resonancia magnética, radiografía digital) no sólo permiten obtener imágenes reales del cuerpo, sino que generan un conjunto de datos almacenables (Ficheros DICOM) que permiten la reconstrucción 3D, 4D y 5D. Este tipo de ficheros permiten todo tipo de tareas de análisis y proceso de imagen, permitiendo examinar una parte corporal de una manera muy precisa e interactiva. Basándonos en la experiencia que nos da el empleo rutinario de estas técnicas en el sujeto vivo y en algunos casos de fallecidos, esta innovación tecnológica se presenta como un instrumento de gran utilidad docente en Antropología Biológica y Biomedicina

    Multi-constellation GNSS interferometric reflectometry with mass-market sensors as a solution for soil moisture monitoring

    [EN] Per capita arable land is decreasing due to the rapidly increasing population, and fresh water is becoming scarce and more expensive. Therefore, farmers should continue to use technology and innovative solutions to improve efficiency, save input costs, and optimise environmental resources (such as water). In the case study presented in this paper, the Global Navigation Satellite System interferometric reflectometry (GNSS-IR) technique was used to monitor soil moisture during 66¿d, from 3 December 2018 to 6 February 2019, in the installations of the Cajamar Centre of Experiences, Paiporta, Valencia, Spain. Two main objectives were pursued. The first was the extension of the technique to a multi-constellation solution using GPS, GLONASS, and GALILEO satellites, and the second was to test whether mass-market sensors could be used for this technique. Both objectives were achieved. At the same time that the GNSS observations were made, soil samples taken at 5¿cm depth were used for soil moisture determination to establish a reference data set. Based on a comparison with that reference data set, all GNSS solutions, including the three constellations and the two sensors (geodetic and mass market), were highly correlated, with a correlation coefficient between 0.7 and 0.85.Martín Furones, ÁE.; Ibañez Asensio, S.; Baixauli, C.; Blanc Clavero, S.; Anquela Julián, AB.
