Authors: Judistira Aldia Deponsa , Pratondo Agus , Sularsa Anang
Published: June 2023

The advance of educational technology is significantly changing and is very effective in supporting education nowadays. However, technology to support education in Indonesia is not maximal; one of the cases occurred in the PGRI Sumedang Kindergarten. Teachers at PGRI Sumedang Kindergarten have difficulties providing material that can build students’ interest, especially general knowledge about animals. This study aims to design Augmented Reality (AR) technology features with Speech Recognition for an Android-based interactive multimedia application of animal knowledge to assist learning activities in PGRI Sumedang Kindergarten. AR is a computer technology that combines virtual objects with the real world. This AR feature uses a card-shaped marker with an image and speech recognition as a medium for interaction with animals. Speech recognition is a computer technology to process human speech into digital letters or words. The resulting interaction is that if the user pronounces the animal’s name displayed in AR, the animal animation will move. This AR feature can help to learn activities at Kindergarten PGRI Sumedang.

Authors: Davuluri Raghava S. C. , Fu Rui , Tagavi Kaveh A. , Martin Alexandre
Published: June 2023

A material response code is strongly coupled with a radiative transfer equation (RTE) to evaluate the effect of a spectrally resolved heat flux on the thermal response of a heat shield. A [Formula: see text] approximation model of RTE is used to account for radiation heat transfer within the material. First, the RTE model is verified by comparing the numerical results with the analytical solution. Next, the coupling scheme is verified by comparing the temperature histories computed by the pure conduction scheme with the ones computed by conduction coupled with radiative emission. The verification study is conducted using test cases from the literature (radiant heating, arc jet heating, and space shuttle entry) as well as on a 3D Block, a 2D IsoQ sample, and the Stardust Return Capsule. The verification results are satisfactory for all cases. Thus, the verification results indicate that the coupling approach can accurately simulate the thermal response of the material. The coupling scheme was then used to simulate a laser heating experiment that studied the impact of spectral radiative heat transfer on ablative material. The results from the laser ablation simulations exhibit a behavior analogous to the experimental observations, indicating the importance of spectral radiative flux on the material response.

Published: June 2023

The Arctic Zone of the Russian Federation is a region with special business support conditions. In 2020, it included the municipal districts of the republics of Karelia, Komi and the Arkhangelsk region, where dairy farming was a traditional activity. Since early 1990s, agriculture in these areas has been in a deep crisis and unable to overcome it. The analysis revealed a close relationship between the reduction in the number of cows and the decrease in the area of cultivated arable land in municipal districts. The number of cows decreased by 25 times in 3 regions, by 15 times in 5 regions, the areas under crops in all categories of farms — by 36 and 15 times, respectively. The shallow contour of the fields, the spread of agricultural land across the territory, the lack of a developed transport infrastructure in the Arctic zone do not allow realizing economies of scale and reducing costs through large investment projects, such as mega-complexes with a conveyor type of production being built in the central and Southern regions of Russia. Automation of production processes, digitalization of management increase productivity and quality, reduce resource intensity and operating costs. Mastering digital technologies for monitoring, modeling and control in operational management and planning increase the efficiency of using agro-climatic and natural potential, reduce production and investment risks. The regional specifics of fodder and milk production in the Northern regions determines the expediency of preferential support for the innovative development of dairy farming in small and medium-sized enterprises, family farms, which makes it necessary to improve the forms of state support for investments.
High-throughput deconvolution of native protein mass spectrometry imaging datasets for mass domain analysis.
Authors: Hale Oliver , Cooper Helen , Marty Michael
Published: June 2023

Protein mass spectrometry imaging (MSI) with electrospray-based ambient ionization techniques, such as nanospray-desorption electrospray ionization (nano-DESI), generates datasets in which each pixel corresponds to a mass spectrum populated by peaks corresponding to multiply-charged protein ions. Importantly, the signal associated with each protein is split among multiple charge states. These peaks can be transformed into the mass domain by spectral deconvolution. When proteins are imaged under native/non-denaturing conditions to retain non-covalent interactions, deconvolution is particularly valuable in helping interpret the data. To improve acquisition speed, signal-to-noise ratio, and sensitivity, native MSI is usually performed using mass resolving powers that do not provide isotopic resolution, and conventional algorithms for deconvolution of lower-resolution data are not suitable for these large data sets. UniDec was originally developed to enable rapid deconvolution of complex protein mass spectra. Here, we developed an updated feature set harnessing the high-throughput module, MetaUniDec, to deconvolve each pixel of native MSI datasets and transform m/z-domain image files to the mass domain. New tools enable reading, processing, and output of open format .imzML files for downstream analysis. Transformation of data into the mass domain also provides greater accessibility, with mass information readily interpretable by users of established protein biology tools such as SDS-PAGE.
Machine Learning-Augmented Docking. 1. CYP inhibition prediction
Authors: Moitessier Nicolas , Weiser Benjamin , Genzling Jérôme , Burai Patrascu Mihai , Rostaing Ophélie
Published: June 2023

A significant portion of the oxidative metabolism carried out by the human body is accomplished by six Cytochrome P450 (CYP) enzymes. The binding of small molecules to these enzymes affects drug activity and half-life. Additionally, the inhibition or induction of a CYP isoform by a drug can lead to drug-drug interactions, which in turn can lead to toxicity. In order to predict CYP inhibition, a variety of computational methods have been used, with docking methods being less accurate than machine learning (ML) methods. However, the latter learning methods are sensitive to training data and show reduced accuracy on test sets outside of the chemical space of the training set. In contrast, docking methods do not have this generalization issue and allow for visual analysis. We hypothesize that combining ML methods with docking can lead to improved results when predicting CYP inhibition. To test this hypothesis, we pair our in-house docking program FITTED with several ML techniques to investigate the accuracy and transferability of this hybrid methodology, which we term ML-augmented docking. We find that ML-augmented docking can significantly improve the accuracy of docking software while showing that using ligand features only provides similar accuracy. The generalisability of our docking and ligand-only ML models shows that the ML-augmented docking is modestly more generalizable than ligand machine learning.

SLIT/ROBO signaling impacts many aspects of tissue development and homeostasis, in part, through the regulation of cell growth and proliferation. Recent studies have also linked SLIT/ROBO signaling to the regulation of diverse phagocyte functions. However, the mechanisms by which SLIT/ROBO signaling acts at the nexus of cellular growth control and innate immunity remain enigmatic. Here, we show that SLIT2-mediated activation of ROBO1 leads to inhibition of mTORC1 kinase activity in macrophages, leading to dephosphorylation of its downstream targets, including transcription factor EB and ULK1. Consequently, SLIT2 augments lysosome biogenesis, potently induces autophagy, and robustly promotes the killing of bacteria within phagosomes. Concordant with these results, we demonstrate decreased lysosomal content and accumulated peroxisomes in the spinal cords of embryos fromRobo1−/−,Robo2−/−double knockout mice. We also show that impediment of auto/paracrine SLIT-ROBO signaling axis in cancer cells leads to hyperactivation of mTORC1 and inhibition of autophagy. Together, these findings elucidate a central role of chemorepellent SLIT2 in the regulation of mTORC1 activity with important implications for innate immunity and cancer cell survival.

Desde tiempos remotos las algas marinas han sido utilizadas como fuente de alimento, especialmente en países asiáticos, y en occidente se había limitado su aplicación solo al campo farmacéutico e industrial. Sin embargo, existen propiedades en la estructura y composición de las macroalgas que pueden ser beneficiosas en el área alimenticia, además de poder ser incluidas en la dieta como alimentos funcionales y nutraceúticos. Se buscó evaluar el potencial nutraceútico de las macroalgas marinas provenientes de Ecuador, analizar sus resultados, evidenciar componentes nutricionales más abundantes y establecer sus usos alimenticios más beneficiosos. Es un estudio descriptivo y documental con enfoque cualitativo. Se realizó la revisión y selección de artículos de índole científica cuya fuente principal fueron buscadores como Google Scholar, bases de datos como Scopus y Scielo, aplicándose filtros con palabras relacionadas al estudio de las algas y componentes nutricionales. Los estudios incluidos datan de años entre 1986 y 2021. De acuerdo al análisis documental realizado, se pudo detallar que en la mayoría de los casos se estudiaron tres clases de algas: rojas, verdes y pardas, cuyos componentes principales son altos en fibra, proteínas, carbohidratos, vitaminas y lípidos. Los usos y beneficios que se les puede dar a las macroalgas son muy amplios, su principal característica es ser un alimento natural y rico en macro y micronutrientes esenciales para el ser humano, por lo que su estudio aún continúa.

Published: June 2023

Resumen: Actualmente, más del 10 % de la población está afectada por algún tipo de Trastorno Específico del Aprendizaje (TEAp). Por tal motivo, el objetivo fue analizar trabajos científicos que examinen las relaciones con el mejor desempeño de los estudiantes con TEAp o Dificultad de Aprendizaje (DA) a través del desarrollo de habilidades y competencias socioemocionales que aumentan el grado de motivación, como el trabajo en equipo. Para ello se realizó una revisión sistemática de artículos publicados entre 2014 y 2021, a través de bases de datos de indexación de acceso abierto, en inglés, portugués y español. De los 146 artículos encontrados, siguiendo el método PRISMA y mediante el cribaje definitivo, se incluyeron 16 publicaciones, en las que se encuentran presentes la tríada docente, padres de familia y estudiantes de educación básica. Los resultados indican que las acciones se enfocan en el desarrollo y aprendizaje de los estudiantes con DA o TEAp y los posibles cambios en la percepción emocional que provocan dificultades de aprendizaje. Como sugerencia, están la creación de políticas públicas adecuadas para la evaluación continua de los estudiantes, la reflexión sobre las prácticas pedagógicas a través de la formación docente y el trabajo cercano entre las partes involucradas en el proceso.

Resumen: En el mes de marzo del año 2020, la Organización Mundial de la Salud (OMS) caracteriza el COVID-19 como una pandemia, razón por la cual se establecen protocolos de prevención que sugieren, entre ellos, aislamiento y distanciamiento social. Los psicólogos alrededor del mundo, con el fin de acatar tales disposiciones, han buscado implementar la tele psicología en sus servicios. El objetivo principal de la investigación fue comparar la eficacia de la tele psicología frente a la presencialidad e identificar las ventajas e inconvenientes presentados durante la pandemia. La metodología utilizada para el análisis de revisión sistémica, tiene un enfoque cualitativo, con un alcance descriptivo. El lapso de tiempo en el que se recabó la información fue durante el primer cuatrimestre del 2021 en las bases de datos: Science direct, Dialnet, Ebsco host, Taylor & Francis Online, Jstor, Scopus, ProQuest, entre otras.  Se obtuvo, como resultado, un total de 840 estudios, de los que 37 fueron escogidos tras superar los criterios previos de selección y discriminación, citados en la guía PRISMA. A partir de la revisión de diversos artículos relacionados a la tele psicología y su desarrollo durante la pandemia, se evidenció eficacia en diferentes enfoques, con una mayoría significativa en aquellos basados en los modelos Cognitivo-Conductual, referente a sus ventajas e inconvenientes se han extraído varios, que han sido contrastados con la terapia en formato presencial. Finalmente se ha explorado su desarrollo, evidenciándose un crecimiento incipiente ante la necesidad de adaptarse a las restricciones impuestas por la OMS para evitar la propagación del virus SARS-CoV-2 en la población.
REVISION SISTEMÁTICA SOBRE PSICOTERAPIAS EFECTIVAS Y/O TRATAMIENTOS COMBINADOS CON PACIENTES CON SEVERIDAD Y COMORBILIDAD
Authors: Scherb Elena Diana
Published: June 2023

Resumen: Existen actualmente una variedad de psicoterapias efectivas para la mayoría de los trastornos psicopatológicos. Cuando el diagnóstico implica severidad y comorbilidad en la sintomatología psiquiátrica la indicación es tratamiento combinado, medicación y psicoterapia. Este estudio de revisión sistemática tiene como objetivo recolectar artículos científicos sobre las psicoterapias efectivas y/o tratamientos combinados con pacientes con severidad y comorbilidad desde la perspectiva de las prácticas basadas en evidencias. Para ello se aplicó lo formulado en la declaración PRISMA y el criterio PICOS. En una primera búsqueda se seleccionaron 95 (N=95) artículos, el 90 % proveniente de bases de datos de Europa y Estados Unidos. Se realizaron otras 3 búsquedas, la primera con las palabras clave ¨psicoterapias basadas en evidencias y tratamientos combinados¨, la segunda con ¨psicoterapia y medicación¨ y la tercera con ¨psicoterapia basada en evidencias¨, de las cuales se seleccionaron 53 (N=53) artículos, pero se excluyeron las bases Europa y USA porque arrojaron resultados demasiado extensos. En los países más desarrollados, se observa una presencia significativamente mayor de estudios de investigación sobre eficacia y efectividad de las psicoterapias combinadas dirigidos a trastornos específicos, incluyendo severidad y comorbilidad, coherente con una mayor disponibilidad de financiamiento para llevarlos adelante. Dada la alta prevalencia y el elevado monto de sufrimiento que acarrean los pacientes y sus allegados, se destaca la importancia de difundir estos conocimientos para mejorar los resultados de las psicoterapias con estos pacientes.

Published: June 2023

Resumen: El conocimiento científico acerca de la Metodología de la Investigación abarca a las diversas disciplinas, y postulándose en este artículo los estudios Metaanáliticos, de Metasíntesis y de Revisión Sistemática en el marco de su aplicabilidad a las ciencias sociales, y en particular a la ciencia psicológica. En el marco del crecimiento y avance de la ciencia, las demandas imperiosas de ordenar el saber, compararlo y contrastarlo dan lugar a estudios de Revisión Sistemática, Metasíntesis y Metaanáliticos, que, si bien no aportan un conocimiento acabado del tema, nutren acerca de las publicaciones y aportan mayor evidencia científica.  Las Revisiones Sistemáticas indican análisis de estudios de carácter primario llevados adelante con carácter reproductible a través de métodos explícitos. Los Metaanálisis deben incluir una síntesis matemática de resultados primarios dirigidos frente a problemas de investigación similares o hipótesis con diseños similares. La pesquisa postula el avance de la psicología como ciencia en el marco interdisciplinar a través de las metodologías de Revisión.
REVISIÓN SISTEMÁTICA DE LA PREPARACIÓN PARA DESASTRES EN EL CONTEXTO DE LA PANDEMIA COVID-19.
Authors: Da Matta Felisberto João Luiz
Published: June 2023

RESUMEN: Los impactos de COVID-19 y las medidas para controlarlo plantean aún más preguntas sobre la preparación para desastres que abarca el conocimiento y las capacidades desarrolladas por gobiernos, organizaciones, comunidades e individuos para anticipar, responder y recuperarse de los impactos de desastres probables, inminentes o actuales. Este estudio tiene como objetivo analizar las publicaciones realizadas entre 2020 y 2021 sobre la preparación para desastres en el contexto de la pandemia COVID-19. Por tanto, utiliza la Revisión Sistemática, de tal forma que encaja como multidisciplinar, abarcando, en particular, las áreas de las Ciencias Humanas y Sociales, a partir de un conjunto teórico-conceptual para dar respuesta al objetivo propuesto. Se siguieron los pasos de calidad del método PRISMA-NMA, de tal manera que se analizaron 27 artículos científicos publicados en el período de 2020 a 2021, con acceso al texto completo, publicados en el área de las ciencias humanas, sociales y multidisciplinarias, y cuyo objeto de investigación esté relacionado con la preparación para desastres. De los 27 artículos seleccionados para esta Revisión Sistemática, 66,7 % hacen sus inferencias a partir de una revisión de la literatura, 70,4 % aborden directamente temas relacionados con las políticas públicas y solo 7,4 % abordan temas relacionados con la salud mental de los involucrados en desastres. La salud mental de las personas involucradas en desastres sigue siendo un tema poco desarrollado en los estudios sobre preparación para desastres. La formulación de políticas públicas requiere la capacidad de implementar una estrategia coherente para proteger a las poblaciones.
USO DE PSEUDOHOMÓFONOS EN LECTURA Y RECONOCIMIENTO DE PALABRAS: UNA REVISIÓN SISTEMÁTICA EN ORTOGRAFÍAS TRANSPARENTES
Authors: Difalcis Micaela , Morello-García Florentina
Published: June 2023

Resumen: La presente revisión sistemática tuvo como objetivo examinar la utilización de pseudohomófonos en tareas de lectura y reconocimiento de palabras en lenguas consideradas de ortografía transparente. Se realizó una revisión sistemática de la literatura disponible de los últimos 15 años y hasta mayo de 2022 en diversas bases (PubMed, Scopus y SciELO). Se buscaron artículos originales de los últimos 15 años que hayan evaluado la lectura y/o el reconocimiento de palabras en participantes adultos sin alteraciones y que hayan empleado pseudohomófonos como estímulo. La búsqueda arrojó un total de 188 registros de los cuales 19 cumplieron con los criterios de inclusión. Se identificaron distintas tareas de reconocimiento y lectura en voz alta, aunque la más utilizada fue la decisión léxica visual. Además, y en gran parte debido a las características ortográficas de cada lengua, se observaron distintas formas de construir los pseudohomófonos. Los estudios revisados reportan hallazgos de tareas conductuales, técnicas neurofisiológicas, neuroimágenes y de movimiento oculares. Dentro de los resultados conductuales, la tasa de acierto/error y los tiempos de reacción fueron las fuentes de datos principales. Se puede concluir que los pseudohomófonos constituyen una importante herramienta para estudiar el rol de la información fonológica en la lectura y el reconocimiento de palabras.

RESUMEN: Laeación suicida en los adolescente es una problemática universal y latente, esta ideación se genera debido a las distintas situaciones de vulnerabilidad que atraviesan los jóvenes, entre ellas está la violencia en las relaciones de pareja mediante las redes sociales. El objetivo de esta investigación fue estudiar la relación entre la violencia de parejas en redes sociales y la ideación suicida en adolescentes de instituciones educativas de la ciudad de Milagro. Para esto se realizó una investigación básica no experimental, con enfoque cuantitativo de alcance correlacional de campo y transversal. Los instrumentos empleados fueron la Escala de Violencia de Pareja en las Redes Sociales en Adolescentes (e-VPA) y la Escala de Ideación Suicida de Beck (Suicide Intent Scale, SIS), estas herramientas se aplicaron a 206 participantes de 16 años en edad promedio. Los resultados mostraron que la violencia de pareja en redes sociales está relacionada con la ideación suicida en los adolescentes. Es posible que de no estudiar estas variables los adolescentes a mediano plazo sean protagonistas de hogares disfuncionales o posibles suicidios consumados.
