La imagen y la narrativa como herramientas para el abordaje psicosocial en escenarios de violencia. Municipios de Ricaurte, Sesquilé y Cota Cundinamarca

En el presente trabajo, se logran abordar los contenidos vistos en el Diplomado de Profundización “Acompañamiento Psicosocial en Escenarios de Violencia”, donde se identifican las problemáticas en comunidades de nuestro país víctimas del conflicto armado en Colombia, flagelo que, en el presente, sigue siendo parte de esta realidad y de una guerra sin sentido, que deja a su paso heridas y secuelas tanto físicas como psicológicas; además, de grandes consecuencias psicosociales. Con este material y dicha problemática, se realiza una visión más objetiva y analítica, con la apropiación del enfoque narrativo, la imagen foto voz, la aplicación de preguntas estratégicas, circulares y reflexivas, las cuales permiten ahondar más allá de los relatos de las experiencias vividas, logrando proyectar procesos de acompañamiento psicosocial desde el conocimiento adquirido, a partir de programas de intervención, dirigidos a mejorar la trasferencia positiva de éstos contextos, donde se reconoce la capacidad del ser humano para afrontar las experiencias traumáticas que traen efectos devastadores. Las víctimas logran reestructurar la forma de entender el mundo y construyen nuevos sistemas de valores, por medio de conceptos de resiliencia, que permiten mostrar, que el ser humano, tiene la capacidad de resistir y rehacerse, ante cualquier adversidad en la vida.In this document, it is possible to approach the contents seen in the Diploma of profundization Psychosocial Accompaniment in Scenarios of Violence, where it’s identify the problematic in communities of our country who are victims of the armed conflict in Colombia. This is a problem that in present days continues to be part of this reality and a meaningless war, which leaves wounds and consequences both physically and psychologically, as well as great psychosocial consequences. With this material and the problematic mention before, it is possible to approach from a more objective and analytical vision, with the appropriation of the narrative approach, the photo-voice image, the application of strategic, circular and reflective questions, which allow us to go further from the stories of the lived experiences, making possible to project psychosocial accompaniment processes from the acquired knowledge, from intervention programs aimed at improving the positive transfer of these contexts, where it recognizes the capacity of the human being to face the traumatic experiences that bring devastating effects. The victims manage to restructure the way of understanding the world and build new value systems through concepts of resilience that show that the human being has the ability to resist and to remake himself truth the adversity in life

Anthropometric correlates of muscle obsession / Correlatos antropométricos de la obsesión por la musculatura

Abstract To date, few studies have assessed the relationship between anthropometric measures and drive for muscularity (DM). Therefore, the purpose of this study was to examine anthropometric correlates of DM. 76 college men answered the Drive for Muscularity Scale, and individually their weight, height and four skinfolds (biceps, triceps, suprascapular, and suprailiac) were measured. There were no significant correlations between DMS total score and anthropometric indicators (body mass index, body density, body-fat percentage, fat-free mass index, and waist to hip ratio). Anthropometric indices were not related to the DM, suggesting that the current body composition of participants was not related to the DM. The fact that the fat-free mass index was not associated with DM is significant because we expect more DM in men with average muscularity. One possible explanation is that the DM could be associated with body shape, rather than lean body mass. The findings of this study increase our understanding of the DM in men and may help in designing interventions to decrease the DM. Key words: Drive for Muscularity Scale, body mass index, fat-free mass index, body-fat percentage, male.   Resumen A la fecha, pocos estudios han evaluado la relación entre las medidas antropométricas y la obsesión por la musculatura (OM). Por lo anterior, el propósito de este estudio fue examinar los correlatos antropométricos de la OM. 76 varones universitarios contestaron la Escala de Obsesión por la Musculatura e individualmente se midió su peso, su talla y cuatro panículos adiposos (biceps, triceps, supraescapular y suprailiaco). No se observaron correlaciones significativas entre la puntuación total de la OM y los indicadores antropométricos (índice de masa corporal, densidad corporal, porcentaje de grasa, índice de masa libre de grasa e índice cintura cadera). Los índices antropométricos no se relacionaron con la OM, lo cual sugiere que la composición corporal actual de los participantes no se relaciona con la OM. El hecho de que el índice de masa libre de grasa no se relacionó con la OM es notable porque se esperaría mayor OM en los hombres con musculatura media. Una posible explicación es que la OM podría asociarse con la figura corporal, más que con la masa muscular corporal. Los hallazgos del presente estudio incrementan nuestro conocimiento de la OM en varones y pueden contribuir en el diseño de intervenciones enfocadas a disminuir la OM. Palabras clave: Escala de Obsesión por la Musculatura, índice de masa corporal, índice de masa libre de grasa, porcentaje de grasa corporal, varones.

Conducting polymer 3D microelectrodes

Conducting polymer 3D microelectrodes have been fabricated for possible future neurological applications. A combination of micro-fabrication techniques and chemical polymerization methods has been used to create pillar electrodes in polyaniline and polypyrrole. The thin polymer films obtained showed uniformity and good adhesion to both horizontal and vertical surfaces. Electrodes in combination with metal/conducting polymer materials have been characterized by cyclic voltammetry and the presence of the conducting polymer film has shown to increase the electrochemical activity when compared with electrodes coated with only metal. An electrochemical characterization of gold/polypyrrole electrodes showed exceptional electrochemical behavior and activity. PC12 cells were finally cultured on the investigated materials as a preliminary biocompatibility assessment. These results show that the described electrodes are possibly suitable for future in-vitro neurological measurements

Perception of students at the Universidad Complutense de Madrid of teaching quality in the pandemic: Evaluation through Docentia-UCM

[EN] The evaluation of the impact of the pandemic on the quality of teaching has been carried out using a statistical study of the variability of the students responses to some of the questions used in the online questionnaire used by students in the evaluation of teachers in the Docentia-UCM Program, which allows thousands of responses to be obtained in a little time and which can be stored and used in multiple formats. The questionnaire has been developed for students to evaluate the dimensions of the model related to Planning, Development and Results. Since the survey is sent by email to all students, we cannot consider a probability sample and would have a non-probability sampling frame with a convenience sample in which respondents are self-selected. The distortion of the sample due to self-selection means that the results are limited to the specific framework in which Docentia-UCM is developed, so they cannot be generalized outside the context evaluated. The comparison of means between the two quarters of the 2019-2020 academic year was carried out using ANOVA. The study shows that there are statistically significant differences between the two four-month periods, as well as the indicators that have changed the most since the start of the pandemic. In these indicators, a polarization of the answers has been observed and an evolution of the same to more positive values, highlighting the indicators of accessibility of teachers and the promotion of interest in the subject.[ES] La evaluación del impacto de la pandemia sobre la calidad de la docencia se ha llevado a cabo utilizando un estudio estadístico de la variabilidad de las respuestas del estudiantado a algunas de las cuestiones utilizadas en el cuestionario online que utilizan los estudiantes en la valoración del profesorado en el Programa Docentia-UCM, que permite obtener miles de respuestas en poco tiempo y que pueden almacenarse y utilizarse en múltiples formatos. El cuestionario ha sido desarrollado para que los estudiantes evalúen las dimensiones del modelo relacionadas con Planificación, Desarrollo y Resultados. Dado que la encuesta se envía por correo electrónico a todos los estudiantes, no podemos considerar una muestra probabilística y tendríamos un marco muestral no probabilístico con una muestra de conveniencia en la que los respondientes son autoseleccionados. La distorsión de la muestra por la autoselección hace que los resultados se limiten al marco específico en el que se desarrolla Docentia-UCM, por lo que no son generalizables fuera del contexto evaluado. La comparación de medias entre los dos cuatrimestres del curso 2019-2020 se llevó a cabo mediante ANOVA. El estudio muestra que hay diferencias estadísticamente significativas entre los dos cuatrimestres, así como los indicadores que más han cambiado tras el inicio de la pandemia. En dichos indicadores se ha observado una polarización de las respuestas y una evolución de las mismas a valores más positivos, destacando los indicadores de accesibilidad de los docentes y el fomento del interés por la asignatura.Segovia Guisado, JM.; Cano Maganto, A.; Uriol Pulido, J.; De León González, ME.; Martín López, S.; Egea Mota, MDM.; Carabantes Alarcón, D....

Doped Overoxidized Polypyrrole Microelectrodes as Sensors for the Detection of Dopamine Released from Cell Populations

A surface modification of interdigitated gold microelectrodes (IDEs) with a doped polypyrrole (PPy) film for detection of dopamine released from populations of differentiated PC12 cells is presented. A thin PPy layer was potentiostatically electropolymerized from an aqueous pyrrole solution onto electrode surfaces. The conducting polymer film was doped during electropolymerization by introducing counter-ions in the monomer solution. Several counter-ions were tested and the resulting electrode modifications were characterized electrochemically to find the optimal dopant that increases sensitivity in dopamine detection. Overoxidation of the PPy films was shown to contribute to a significant enhancement in sensitivity to dopamine. The changes caused by overoxidation in the electrochemical behavior and electrode morphology were investigated using cyclic voltammetry and SEM as well as AFM, respectively. The optimal dopant for dopamine detection was found to be polystyrene sulfonate anion (PSS-). Rat pheochromocytoma (PC12) cells, a suitable model to study exocytotic dopamine release, were differentiated on IDEs functionalized with an overoxidized PSS--doped PPy film. The modified electrodes were used to amperometrically detect dopamine released by populations of cells upon triggering cellular exocytosis with an elevated K+ concentration. A comparison between the generated current on bare gold electrodes and gold electrodes modified with overoxidized doped PPy illustrates the clear advantage of the modification, yielding 2.6-fold signal amplification. The results also illustrate how to use cell population based dopamine exocytosis measurements to obtain biologically significant information that can be relevant in, for instance, the study of neural stem cell differentiation into dopaminergic neurons
