Objetivo: Descrever o comportamento sedentário entre professores da educação básica da rede pública estadual e identificar fatores associados à elevada exposição a este comportamento. Métodos: Websurvey realizado com professores da educação básica das escolas estaduais de Minas Gerais. A variável dependente referiu-se ao Comportamento Sedentário, expresso pela indicação do Tempo Sentado Total, calculado com base nos dados do Questionário Internacional de Atividade Física. Foram classificados como possuindo “elevada exposição ao comportamento sedentário” (EECS), indivíduos que indicaram permanecer, em média, mais de 5 horas por dia na posição sentada. Resultados: Participaram do estudo 1.907 professores. Houve predomínio de mulheres e 40,9% apresentaram EECS. No modelo final, professores mais velhos, com filhos menores de 10 anos e com menor renda familiar apresentaram menores prevalências de EECS. A maior prevalência de EECS foi observada nos que não apresentavam união estável, não residiam em proximidade a áreas de lazer, que estavam insatisfeitos com o trabalho, que possuíam pior padrão alimentar e que apresentavam dependência do smartphone. Conclusão: Mais de 40% dos professores permaneciam sentados por tempo superior a 5 horas diárias. Faz-se necessária a formulação de políticas públicas para obter controle desse comportamento entre os professores, a fim de proteger a saúde desses profissionais.

Objetivo: Avaliar a influência das fases do ciclo menstrual sobre o processamento da atenção e da memória de estudantes universitárias com idade entre 20 e 26 anos. Métodos: Trata-se de um estudo realizado com 76 universitárias com ciclo menstrual regular. As participantes foram divididas em quatro grupos relativos às quatro fases do ciclo menstrual e foram submetidas aos testes de Aprendizagem Auditivo Verbal de Rey, Figuras Complexas de Rey e Atenção. Resultados: Os resultados demonstraram diferenças importantes entre os grupos. O grupo da fase menstrual apresentou um desempenho, significativamente, melhor do que o grupo da fase ovulatória no teste de Figuras Complexas de Rey. Isto demonstra que, provavelmente, foram as alterações hormonais advindas das diferentes fases do ciclo que caracterizaram as diferenças. Conclusão: Esses resultados nos permitem inferir que a diminuição dos níveis plasmáticos de estrógeno tem um papel benéfico de melhorar de forma significante e seletiva os processos de armazenamento da memória visual. Assim, este artigo pode ajudar a entender o papel dos esteróides sexuais no funcionamento neuropsicológico, particularmente sobre a relação entre o estrogênio e os mecanismos de memória.

Authors: Junior Nelson Kautzner Marques
Published: April 2024

Background and Study Aim. The sportive periodization originated from the military periodization of ancient civilizations and of the Greek Tetrad for the sportive preparation the ancient Greek athletes. The objective of the review was to explain the periodization of the Roman military training. Materials and Methods. The articles were selected in January and February of 2024 in 10 databases (Google Scholar, PubMed, Research Gate, Scielo, Redalyc, Scopus, DOAJ, ScienceDirect, Semantic Scholar, and Latindex) with the following keywords: Roman military training, Roman soldiers, Roman Empire territory, Tetrad during Roman military training, Roman military equipment, and Roman military tactics. Results. Ancient Rome conquered almost all Western Europe, North Africa, and part of the Middle East because the nation was very militarized. The military training during ancient Rome for the soldiers and sailors had several types of training that were physical training, training, technical training, and technical and tactical training. So, for the war coach to organize all these training sessions for the Roman military, he needed to structure the periodization. The periodization of the Roman military training was used with several mesocycles of 4 to 6 months of duration during various moments of the year for the soldier and the sailor to always be prepared for war. In 146 B.C., the Roman Empire conquered ancient Greece and after this moment, the Romans used the scientific knowledge of the Greeks to structure the Roman military training. Then, the Romans used the Tetrad of the Greeks to structure the military training. Roman military training was structured with several Tetrad during 4 to 6 months. Therefore, the Tetrad was inserted into the mesocycle of 4 to 6 months. Conclusions. In conclusion, the periodization of the Roman military training was very organized for the military to achieve a high performance in the war.

Understanding the mechanisms of assembly and disassembly of macromolecular structures in cells relies on solving biomolecular interacFons. However, those interacFons o_en remain unclear because tools to track molecular dynamics are not sufficiently resolved in Fme or space. In this study, we present a straighaorward method for resolving inter- and intra- molecular interacFons in the adhesive machinery, using Quantum Dot based Förster Resonance Energy Transfer (FRET) nanosensors. IniFally, we measured the interacFon between Talin, a crucial protein responsible for force transmission in focal adhesions, and the membrane on which it assembles. We quanFfied the distances separaFng Talin and the membrane in three Talin molecular variants. Secondly, we invesFgated the mechanosensing capabiliFes of Talin, which means its unfolding due to mechanical stretching iniFated by cytoskeleton contracFon. For the first Fme, quantum dot-based nanosensors have enabled the quanFficaFon of mechanosensing, using the example of Talin behavior as a consequence of cytoskeletal tension. SensiFve unfolding mechanism of the protein and its assembling to the membrane were measured with sub-nanometer accuracy.

Published: April 2024

Infectious wounds occur when harmful microorganisms such as bacteria or viruses invade a wound site. Its problems associated include delayed healing, increased pain, swelling, and the potential for systemic infections. Therefore, developing new wound dressing materials with antibacterial effects is crucial for improving the healing process. Here we developed a redox-degradable hydrogel loaded with an antibacterial peptide (vancomycin) in a straightforward gram-scale synthesis. The hydrogel structure consists of a disulfide bond-containing hyperbranched polyglycerol (SS-hPG) which is cross-linked by 4-arm polyethylene glycol-thiol (4-arm PEG-SH). The polymerization mechanism and full characterization of SS-hPG are described as we report this synthesis for the first time. The controlled release of antibacterial peptide follows, as the hydrogel degrades in a reductive environment triggered by glutathione. We used rheology to ascertain the hydrogel’s mechanical characteristics, such as stiffness, and self-healing, determining these properties for different ratios and concentrations of both blocks. Fluorescein isothiocyanate-albumin (FITC-albumin) and vancomycin were both loaded into the gel, and the guest release kinetics were assessed for both slow and ondemand releases. Finally, our in-vitro and in-vivo experiments proved that the vancomycin-loaded hydrogel acts as an antibacterial barrier for wound dressing and accelerates the healing of infectious wounds in a mouse model.

Published: April 2024

Photon upconversion (UC) from red or near-infrared (NIR) light to blue light is promising for in vivo optogenetics. However, the examples of in vivo optogenetics have been limited to lanthanide inorganic UC nanoparticles, and there have been no examples of optogenetics without using heavy metals. Here we show the first example of in vivo optogenetics using biocompatible heavy metal-free TTA-UC nanoemulsions. A new organic TADF sensitizer, a borondifluoride curcuminoid derivative modified with a bromo group, can promote intersystem crossing to the excited triplet state, significantly improving TTA-UC efficiency. The TTA-UC nanoparticles formed from biocompatible surfactants and methyl oleate acquire water dispersibility and remarkable oxygen tolerance. By combining with genome engineering technology using the blue light-responding photoactivatable Cre-recombinase (PA-Cre), TTA-UC nanoparticles promote Cre-reporter EGFP expression in neurons in vivo. Our results open new opportunities towards deep-tissue control of neural activities based on heavy metal-free fully organic UC systems.
Plant-derived biopolymers initiate heterogeneous ice nucleation via particulate interfaces immersed in supercooled droplets

Published: April 2024

Organic matter can initiate heterogeneous ice nucleation in supercooled water droplets, thereby influencing atmospheric cloud glaciation. Atmospheric organic matter includes biopolymers, which are emitted as primary bioaerosols, biomass burning aerosols, soil dust and sea spray aerosols and can nucleate ice in the absence of a solid surface like mineral dust. There is evidence that biopolymers could form aggregates in solution, thereby creating ice-nucleating sites. However, the submicron size and heterogeneity of these aggregates creates challenges in studying and predicting their ice-nucleating ability. Here, we characterized self-assembled nanoparticles of cellulose and lignin and of two newly identified ice-nucleating biopolymers, namely xylan and laminarin. Our freezing ice nuclei counter (FINC) instrument measured the median ice nucleation temperatures of aqueous cellulose, lignin, xylan and laminarin samples to be –22.9 °C, –22.0 °C, –14.2 °C, and –20.0 °C, respectively. Furthermore, a nanoparticle tracking technique detected and quantified particles in the biopolymer solutions, with mean diameters between 132 nm and 267 nm. A positive trend between size and nucleation temperatures suggests that the biopolymers initiate freezing via particulate interfaces immersed in the supercooled droplets. Finally, we determined ice-active site densities normalized to quantitatively measured surface area and mass of the nanoparticles, to demonstrate how the biopolymers self-assemble in solution and subsequently nucleate ice in supercooled droplets. The mechanism by which biopolymers nucleate ice leads to improved predictive capabilities to estimate the impact of organic aerosols on climate.
Optimum Model-Based Design of Diagnostics Experiments (DOE) with Hybrid Pulse Power Characterization (HPPC) for Lithium-Ion Batteries
Authors: Rhyu Jinwook , Zhuang Debbie , Bazant Martin , Braatz Richard
Published: April 2024

Diagnostics of lithium-ion batteries are frequently performed in battery management systems for optimized operation of lithium-ion batteries or for second-life usage. However, attempting to extract dominant degradation information requires long rest times between diagnostic pulses, which compete with the need for efficient diagnostics. Here, we design a set of efficient optimal hybrid pulse power characterization (HPPC) diagnostics using model-based design of experiment (DOE) methods, applying knowledge of degradation effects on pulse kinetics and cell properties. We validate that these protocols are effective through minimization of uncertainty, and robust with Markov Chain Monte Carlo (MCMC) simulations. Contrary to traditional HPPC diagnostics which use fixed pulse magnitudes at uniformly distributed state of charges (SOC), we find that well-designed HPPC protocols using our framework outperform traditional protocols in terms of minimizing both parametric uncertainties and diagnostic time. Trade-offs between minimizing parametric uncertainty and total diagnostic time can be made based on different diagnostics needs.

Implementing Learner-Centered Teaching Strategies in Family Science
Authors: Scott Jenna C. , Wilson Cynthia B. , Greene Kristen H. , Jeter Nari S.
Published: April 2024

Learner-Centered Teaching (LCT), as opposed to teacher-centered practices, actively engages students in the learning process. In this paper, we discuss the importance of adopting LCT strategies in family science courses to improve student learning outcomes. Family science is particularly apt for LCT because of the interpersonal focus of the discipline. To help fill an important gap in the literature, seven LCT strategies are articulated within the specific context of family science. We highlight the following seven approaches: small group activities, questioning, think-pair-share discussions, gaming, in-class writing, low-stakes quizzes, and flipped classroom design. In addition to describing the approaches, we discuss class size, adapting the techniques for online courses, and working with students who require accommodations. Finally, we share evaluation data from students that speaks to four of the seven LCT strategies. Our hope is that this paper will offer ready-made ideas that family science instructors may adopt. To conclude, we discuss implications, challenges in implementing LCT, and areas of future research.

Authors: Autret Maya , Bermea Autumn , Bible Jacqueline , Matera Kristin , van Eeden-Moorefield Brad
Published: April 2024

This paper details the redesign and implementation of an introductory Family Science and Human Development (FSHD) undergraduate course. The redesign implemented a flipped classroom approach, grounded in constructivist theory and active learning methods. A flipped classroom approach shifts traditional lecture-based classwork to an application-focused, interactive curriculum. More specifically, it shifts students from being passive learners to active, co-constructors of knowledge. Doing so deepens learning through the centering of students, along with their peers, through meaningful exchanges that help prepare them to work in the field with diverse people and families. While flipped classrooms are becoming increasingly popular, given their link to improved learning outcomes, here we seek to address a gap in the literature concerning its application within FSHD, which is well-suited for such an adaptive, flexible, and dynamic pedagogical approach. We particularly highlight our development and use of podcasts and fact sheets to replace textbooks and in-class activities that promote not only the application of content but also skill development.
Integrating Genograms and Expanded Family Development Theory in an Application Project for a Family Science Course
Authors: Nesteruk Olena
Published: April 2024

This paper describes an innovative approach to teaching about family development over the life course through an application project and assesses its effectiveness in student learning. The integration of genograms and expanded family development theory (FDT) into one project aims to provide an engaging and useful structure for the assignment and promote the inclusion of diverse families. In this assignment, students (1) create their family genogram and (2) write an accompanying paper to identify and apply the FDT stages and developmental tasks to each generation of their family. Assessment results demonstrate that this project provided students with a practical opportunity to apply theoretical course content to diverse, real-life families and helped to recognize family trends across generations. Students appreciated the hands-on learning experience and opportunity for self-reflection, which promoted engagement with course materials. Incorporating genograms and the expanding family life cycle helps to overcome the limitations of the original FDT by being inclusive of all families, thus contributing to more effective preparation of competent professionals.

Electrical device characterization has been performed on MOSFETs with high-k gate oxides as well as their reference counterparts with silicon dioxide gate dielectric. In addition, by means of technology simulation with TSUPREM4, models of these devices are established. Current-voltage characteristics and parameter extraction on the simulated structures is conducted with the device simulator MEDICI. Measured and simulated device characteristics are presented and the impact of interface state and fixed charge densities is discussed. Device parameters of high-k devices fabricated with standard poly-silicon gate and replacement metal gate process are compared.
Improvement of LTE Downlink Channel Estimation Performance by Using an Adaptive Pilot Pattern
Authors: Youssef My Abdelkader , Abbadi Jamal El
Published: April 2024

This paper proposes an adaptive pilot pattern to improve channel estimation performance for LTE downlink system with high mobility. The downlink pilot positions are predefined in the time and frequency domain with fixed pilot pattern in LTE standard. However, that pilot structure is not efficient in a fast time varying channel, and leads to a decrease of channel estimation performance. The authors propose and evaluate the performance of LTE downlink channel estimation using an adaptive pilot scheme to optimally use pilot tones over time varying channels. It is shown that only seven bits of additional wide-band feedback per frame and per user are required to optimally support adaptive pilot pattern. Simulation results show that the proposed method allows high performance in terms of throughput and channel estimation error. This analysis shows that LTE downlink throughput could be increased over 4%.

Published: April 2024

Mobile Cloud Networks group together mobile users and clouds containing content servers. Hence, they are an ideal framework for media content delivery. Streamswitching adaptive video players cope well with some limitations of Mobile Cloud Networks as low bandwidth and bandwidth variability in access network. Nonetheless, other limitations, as cloud congestion, are difficult to be managed by the video players. This paper presents a system for discovering fault situations at the cloud (e.g., cloud congestion) and notifying to the video player, which will take appropriate actions for saving the quality of media transmission. In proposed implementation the video application is DASH-capable and adaptation action may be both stream rate adaptation and content server adaptation. The communication between client and server uses “bidirectional” communication feature of HTTP/2 thanks to the new deployed modules running DASH over HTTP/2 in both client’s and server’s applications.

Published: April 2024

The paper presents results of empirical study on creation of added value in Polish telecom sector, based on Economic Value Added (EVA) indicator. First, an EVA analysis was performed for publicly traded telecom companies. Next, the eﬀectiveness of EVA itself in management of telecom companies was evaluated. A statistical analysis was made to investigate dependence between EVA and other indicators of company value, conﬁrming that EVA sign and magnitude are in agreement with indicators based on data from ﬁnancial books. Finally, the eﬀectiveness of using EVA for prediction of market capitalization of telecom companies was investigated. Overall results do not give a clear picture and cannot allow to state that EVA is a better determinant of value of telecom company than ﬁnancial indicators like Earnings Per Share (EPS).
Data Fixing Algorithm in Radiosonde Monitoring Process
Authors: Szuster Piotr
Published: April 2024

Earth surface monitoring can give information that may be used in complex analysis of the air conditions, temperature, humidity etc. Data from a vertical profile of the atmosphere is also essential for accurate thunderstorm forecasting. That data is collected by radiosondes – telemetry instruments carried into the atmosphere usually by balloons. Sometimes, due to the hostile conditions of upper troposphere, incorrect data can be generated by radiosonde sensors. In this paper, a new algorithm is developed for fixing the incorrect data, i.e. missing or out of specific range values. The proposed algorithm was tested both on benchmarks and real data generated by radiosondes. About 70% of significantly damaged test data volume was recovered. Up to 100% of real data was fixed.

Authors: Moscoso Vega Edison Danilo , Arteaga Galvez José Daniel
Published: April 2024

El cáncer gástrico es el quinto cáncer más común en todo el mundo y es responsable de un porcentaje significativo de todas las muertes que se dan debido a esta enfermedad. Actualmente la cirugía sigue siendo el estándar de oro en los tratamientos curativos vistos desde el campo de la oncología. Sin embargo, los tratamientos como la radioterapia, la quimioterapia pueden mejorar los resultados previos o posteriores a la intervención quirúrgica. En tal sentido, se lleva a cabo el tratamiento neoadyuvante antes de la gastrectomía o resección quirúrgica primaria seguida de quimioterapia. Este enfoque, combinado con un descubrimiento temprano y una mejor detección, ha llevado a una disminución de la incidencia general del cáncer gástrico. Lamentablemente, los tumores malignos del estómago se diagnostican en etapas avanzadas o metastásicas cuando la mediana de supervivencia general sigue siendo pobre. La atención quirúrgica en estos casos debe ser brindada por un equipo especializado y de gran envergadura. Los aspectos quirúrgicos son la pieza clave para los resultados, tomando en consideración que la estandarización del tratamiento quirúrgico del cáncer gástrico de acuerdo con el perfil del paciente es de importancia decisiva para un mejor resultado. Esta revisión tiene como objetivo resumir los estándares actuales en el tratamiento quirúrgico del cáncer gástrico.

El bypass gástrico es un procedimiento quirúrgico utilizado para tratar la obesidad mórbida. Consiste en reducir el tamaño del estómago y modificar la ruta del sistema digestivo para limitar la cantidad de alimentos que se pueden consumir y la absorción de nutrientes. Este tratamiento ofrece una solución efectiva para la pérdida de peso significativa y puede mejorar condiciones de salud relacionadas con la obesidad, como la diabetes tipo 2 y la hipertensión. Se trata de una investigación bibliográfica descriptiva, cualitativa en donde se pretende exponer la información necesaria para conocer las Técnicas de derivaciones (bypass) gástrico como tratamiento quirúrgico indicado para pacientes diagnosticados con obesidad mórbida. Para alcanzar el objetivo se revisan artículos científicos, trabajos académicos, sitios web de organizaciones o interés científico académico y los que puedan derivar de repositorios académicos y científicos como PubMed, Scielo, Rialnet entre otros. El bypass gástrico no solo aborda la obesidad mórbida como un problema de peso, sino que también aborda las complicaciones de salud asociadas, como la diabetes tipo 2, la apnea del sueño, la hipertensión y las enfermedades cardíacas. Al reducir significativamente el tamaño del estómago y modificar la ruta del sistema digestivo, esta cirugía ofrece una oportunidad real para que los pacientes logren una pérdida de peso significativa y mejoren su calidad de vida.

Las drogas vasoactivas son fármacos que modifican el tono vascular, la frecuencia cardíaca y la contractilidad miocárdica, con el objetivo de mejorar la perfusión tisular y la oxigenación en el paciente crítico. Estas drogas se clasifican en inotrópicos, vasopresores y vasodilatadores, según su mecanismo de acción y sus efectos hemodinámicos. El uso de las drogas vasoactivas requiere una monitorización estrecha y una valoración continua de la respuesta clínica y los posibles efectos adversos. La elección de la droga vasoactiva más adecuada depende de la etiología, el tipo y la gravedad del shock, así como de las características individuales del paciente. Catecolaminas son los agentes vasoactivos más utilizados en la unidad de cuidados intensivos y, entre ellos, la noradrenalina es el tratamiento de primera línea en la mayoría de las condiciones clínicas. Los inotrópicos están indicados cuando la función miocárdica está deprimida y la dobutamina sigue siendo el tratamiento de primera línea. En este artículo se revisan las principales indicaciones, dosis, vías de administración y precauciones de las drogas vasoactivas más utilizadas en el paciente crítico

Vértigo es la sensación subjetiva de rotación o de desplazamiento del entorno, o del propio cuerpo respecto a sí mismo. Indica un desequilibrio en el sistema vestibular, podemos hablar de vértigo de origen periférico cuando encontramos una lesión a nivel del laberinto o del nervio vestibular y vértigo de origen central si se afectan los núcleos vestibulares del tronco cerebral o sus proyecciones al cerebelo o a la corteza cerebral. La presente investigación se enmarca dentro de una metodología de tipo bibliográfica documental. Ya que es un proceso sistematizado de recolección, selección, evaluación y análisis de la información, que se ha obtenido mediante medios electrónicos en diferentes repositorios y buscadores tales como Google Académico, Science Direct, Pubmed, entre otros, empleando para ellos los diferentes operadores booleanos y que servirán de fuente documental, para el tema antes planteado. En la bibliografía consultada no existe relación entre el vértigo y la aparición de acufenos, lo que se corrobora con la sintomatología que se presenta. En cuanto al tratamiento los estándares son la rehabilitación vestibular, existiendo diferentes maniobras como la Maniobra de Dix Hallpike, Maniobra de Semont y por último la Maniobra de Epley, esta ultima una de las más empleadas.

En el contexto actual, la asociatividad es una herramienta clave para el desarrollo de las comunidades rurales. Las asociaciones permiten a los productores y emprendedores unir sus fuerzas y recursos para mejorar su productividad, acceder a mercados, y obtener mejores precios por sus productos y servicios. El presente estudio tuvo como objetivo proponer estrategias para fortalecer el desarrollo local de los sectores económicos, social y productivos de las asociaciones pertenecientes a la parroquia la América, cantón Jipijapa. Para ello, se llevó a cabo un análisis de la situación actual que presentan estas asociaciones, se identificaron las principales debilidades y fortalezas de cada sector y se sugirieron estrategias específicas para cada uno, las cuales fueron evaluadas por expertos en el tema y por los miembros de las mismas. La población estuvo constituida por un grupo de 6 asociaciones pertenecientes a la parroquia, las técnicas empleadas fueron la encuesta y la observación directa, los datos recolectados fueron ordenados y posteriormente procesados a través de sistemas informáticos del paquete de office Excel. Los resultados que arrojó esta investigación indican que las principales debilidades que tienen las asociaciones se encuentran en la falta de capacitación técnica y en la falta de acceso a financiamiento. Por otro lado, las principales fortalezas se encuentran en la organización y en la capacidad de trabajo en equipo. En base a estos resultados, se espera que logren contribuir a mejorar la calidad de vida de las familias de la parroquia La América y al desarrollo sostenible del cantón Jipijapa.

La investigación actual se centra en el uso del Aprendizaje Basado en Proyectos (ABP) con un enfoque en la educación ambiental. Esto se debe a que la educación ambiental se ha vuelto fundamental para las nuevas generaciones, y sus aspectos potenciales pueden servir como una herramienta para promover el desarrollo sostenible entre los estudiantes. El ABP se elige como método debido a su capacidad para fomentar el pensamiento crítico, permitiendo a los estudiantes aplicar los conocimientos adquiridos a situaciones reales y abordar problemas ambientales. Esto impulsa la investigación y coloca al alumno como el principal agente de su propio aprendizaje, a través de la creación de proyectos que promueven la conciencia ambiental. La propuesta empleada en este estudio busca asegurar una educación de alta calidad para todos los estudiantes a través del Aprendizaje Basado en Proyectos (ABP), ya que este enfoque facilitará la comprensión de la realidad y su transformación mediante proyectos, generando recursos humanos capacitados para generar conocimientos científicos y técnicos, especialmente en el ámbito de los ecosistemas. Para promover una conciencia sostenible en materia de educación ambiental, es fundamental contribuir a la construcción de sociedades socialmente justas y equitativas, en donde todos los miembros de la sociedad vivan en armonía con la naturaleza; así como a la promoción de un medio ambiente democrático y reflexivo para las futuras generaciones. La viabilidad de un futuro sostenible demanda cambios urgentes logrados a través de transformaciones que promuevan el cuidado de la vida en todas sus formas, incluyendo tanto los ecosistemas como los seres humanos, lo que conlleva a la creación de sociedades más equitativas. En este estudio, se empleó una metodología de investigación basada en fuentes bibliográficas para analizar la Metodología del Aprendizaje Basado en Proyectos y los enfoques sobre educación ambiental y el estudio cuantitativo para recopilar datos numéricos por medio de una encuesta estructurada.
