Authors: Mejeras Rastrelli Andrea , Cazzola Duarte Gustavo
Published: November 2024

En este trabajo se pone de manifiesto el vínculo directo que existe entre el perfil del ingeniero iberoamericano y la necesidad de colaborar y cumplir con la Agenda 2030 de la ONU. Si se incorporan los ODS (Objetivos de Desarrollo Sostenible) al proceso de formación académica de los ingenieros, se estará modificando la visión socioeconómico-ambiental del profesional de la Ingeniería. Para ello el profesorado debe saber cómo hacerlo e involucrarse en el proceso. A ellos, entonces, debemos formar: a nuestros Docentes de la Carrera. De ese modo, sabiendo los docentes cómo adecuar sus Cátedras al aprendizaje del Desarrollo Sostenible basado en competencias, es de esperar que nuestros Ingenieros se apropien de una visión distinta del Planeta Tierra y sus habitantes. El Proyecto en marcha en la Facultad Regional Pacheco de la Universidad Tecnológica Nacional, relacionado con del tratamiento académico de las metas del Desarrollo Sostenible que se basa en la capacitación docente y acompañamiento permanente de su plantel en estos ítems, comienza a arrojar resultados positivos respecto del interés de la comunidad educativa en complementar la formación profesional de la Ingeniería en dichos temas, sobre todo si se considera lo prescripto en las Competencias enunciadas por la ASIBEI2.

La accidentalidad de vehículos comerciales ligeros VLC se ha incrementado en los últimos años, a priori en mayor medida por el uso profesional en el ámbito logístico, a mayor demanda del servicio hay mayor movilidad y exposición al riesgo de accidente de tráfico. El objetivo del presente trabajo es analizar las variables de mayor importancia que influyen en la severidad del conductor con implicación de cuatro tipos de VLC de su misma categoría N1, y posteriormente estudiar la tendencia evolutiva de las tasas para la variable más importante para datos del periodo: 2000-2015. En la primera parte de este estudio se describen algunos resultados de modelos de clasificación de severidad de conductor mediante técnicas de Machine Learning, que evidencian el uso del cinturón de seguridad como la variable de mayor importancia en los dos tipos de accidentes analizados. En la segunda parte se aplican modelos jerárquicos bayesianos para el análisis de tendencia en la tasa de uso del cinturón de seguridad de conductores de 2 tipos de VLC y un turismo. En este periodo de tiempo se destaca que la tasa de uso del cinturón de seguridad por parte de los conductores implicados en accidentes mortales (media estadística es de ~73%), porcentaje de uso muy inferior a lo que establecen las encuestas (~90%). El análisis de tendencias para los 3 subconjuntos de conductores indica el incremento del uso de este sistema de seguridad, destacando en mayor proporción de uso en conductores de camiones ligeros. Se recomienda el seguimiento de algunos colectivos específicos con el fin de reducir la probabilidad de comportamientos de riesgo del conductor, como es el caso del no uso del cinturón de seguridad.

La aplicación de técnicas no destructivas para evaluar materiales compuestos sometidos a fatiga es un área de creciente interés entre la comunidad científica. Entre las técnicas disponibles, destaca el uso de la termografía infrarroja debido a su asequibilidad, simplicidad y resultados prometedores en investigaciones previas. En este estudio, se aplica la termografía infrarroja con el objetivo de obtener modelos predictivos capaces de estimar el límite de fatiga de laminados gruesos de CFRP (polímero reforzado con fibra de carbono) sometidos a cargas de tracción. Los ensayos experimentales conllevan la monitorización de la temperatura en laminados con características típicas de la industria aeroespacial, a través de una cámara termográfica. La campaña experimental implica la variación de los niveles de daño por taladrado y las cargas cíclicas de tracción. Con los datos obtenidos de la evolución de la temperatura durante la fase inicial de los ensayos de fatiga se obtienen modelos analíticos predictivos del límite de fatiga. Los resultados indican que el modelo propuesto es capaz de predecir de manera eficiente el límite de fatiga con una alta fiabilidad, mostrando una sólida correlación entre las predicciones y los resultados experimentales, por lo que este estudio subraya la utilidad de las técnicas termográficas para evaluar el daño y predecir el límite de fatiga de laminados CFRP en diversas condiciones de carga

Authors: Huda Miftakhul , Awaludin Arif , Siregar Harrijun Kapabella
Published: November 2024

This article explores the legal challenges in regulating artificial intelligence (AI) with a focus on privacy and data protection laws through a qualitative, comparative study. By employing a library research methodology, the study analyzes existing literature and legal frameworks across multiple jurisdictions to identify common trends, gaps, and inconsistencies in AI regulation. It investigates how various countries, including the European Union, the United States, and emerging economies, have developed or are developing legal instruments to address privacy concerns raised by AI technologies. The study highlights key issues such as the tension between technological innovation and regulatory constraints, the adequacy of current legal standards in addressing AI-specific risks, and the role of international cooperation in harmonizing data protection laws. The comparative analysis reveals significant divergences in how privacy is protected across different regions, particularly in the application of principles like consent, transparency, and accountability. Moreover, the article identifies critical gaps in existing frameworks, including the lack of clarity in AI accountability, data sovereignty, and enforcement mechanisms. The findings underscore the need for a more coherent and globally coordinated approach to regulating AI that balances privacy protection with technological advancement. Ultimately, the study calls for reforms that ensure robust privacy safeguards while fostering innovation in AI.
Two Courts, Two Visions
Authors: Di Franco Eleonora
Published: November 2024

The diverging standards of protection concerning the right to a fair trial, as interpreted by the CJEU and the ECtHR, remain a critical obstacle to the EU’s renewed attempt at accession to the ECHR. In this field, the two Courts seem to be drifting further apart rather than converging, leading to unresolved conflicts between the standard of fundamental rights protection and mutual trust obligations in the EU. Except in the unlikely event of a course-correction by the CJEU, this means that we are no closer to accession today than we were ten years ago, when the now-infamous Opinion 2/13 was handed down.

Published: November 2024

Kalirin, named after the multidextrous Hindu goddess Kali for its ability to interact with multiple proteins, is a GEF (guanine nucleotide exchange factor) for the GTPase (enzyme hydrolyzing guanosine triphosphate to guanosine diphosphate) RAC1 that has been found to correlate with schizophrenia and Alzheimer’s Disease. Restoration of brain function through synaptic plasticity, the ability of neurons to modify the strength of their connections, offers much promise in the struggle against neurodegeneration. Kalirin contributes to synaptic plasticity through regulation of dendritic spine morphogenesis and actin cytoskeleton remodeling, both of which facilitate formation of new synapses. Therefore, developing kalirin selective inhibitors may give valuable insight into its function and possible effects on human health. We developed two novel compounds based on previous research on kalirin inhibitors. We partially confirmed the hypothesis that the in silico model’s accuracy in scoring novel chemical entities is a predictor of biological activity against the RAC1/kalirin target. We designed two novel compounds, we docked them in a computer model of the active site, we synthesized, and then tested their biological activity in an assay and compared against the model’s predictive score for binding to the active site. Compounds 3 and 4 had limited activity against RAC1/kalirin in a nucleotide exchange assay but gave useful insight into future structure-based design and development of kalirin selective inhibitors. Hence, we propose further structural modifications for the synthesis of more biologically potent and selective RAC1/kalirin inhibitors.

Published: November 2024

There is a limited body of research concerning the impact of different attentional foci on the performance or retention of fundamental motor skills in young individuals. Additionally, the influence of verbal cues on sprint performance across various surfaces, such as grass and indoor basketball courts, remains understudied. Therefore, the primary objective of this study was to assess the effectiveness of Internal Cues (IC), External Cues (EC), and analogies with a directional component (ADC) on sprint performance among youth soccer players on different surfaces (grass vs. indoor basketball court). Seventy participants, aged 12.3±0.5 years, with a maturity offset of -0.9±0.5 years, were recruited for this investigation. Multiple 20-meter sprint tests were conducted on both grass and indoor basketball courts using different coaching cues: a control/neutral cue, an internal cue, an external cue, and analogies (away and toward). The analyses did not reveal significant differences (p ≥ 0.05) between cue types for both sprinting on grass and indoor surfaces. However, in post-hoc analyses for indoor sprints, significant distinctions were noted between ECs and ICs, favoring ECs (p < 0.01), as well as between "away" ADC and IC, favoring the "away" ADC (p < 0.01). Similar significant differences were observed for grass sprints, with ECs and "away" ADCs showing superiority over ICs (p < 0.01). In conclusion, the study did not find evidence supporting specific instructional types' positive impact on youth's sprint performance on both grass and indoor surfaces. Notwithstanding, ECs and ADCs seemed to be more effective coaching strategies for improving sprinting performance in youth soccer players. Additionally, motivating young soccer players to give their maximum effort seemed to be a beneficial cueing method for enhancing sprint ability on different surfaces.

Electrochemical lability of glycine in acid media
Authors: Survila Arvydas , Kanapeckaitė Stasė
Published: November 2024

Electrochemical lability of different glycine species is considered on the basis of voltammetric data obtained for hydrogen evolution on the copper electrode in weakly acidic glycine solutions at different potential sweep rates (v). Voltammograms contain well-defined current peaks the height of which depends on both solution pH and glycine concentration. Current peaks and their potentials vary linearly with √−v and log v, respectively, this being typical of the electrochemical processes controlled by diffusion and charge transfer.To characterise system lability, peak coordinates and convolutive transforms of voltammograms are analysed. The results show that protons attached to different groups in a glycine molecule exhibit different mobility. In contrast to the protonated amino group, the release of a proton from the carboxylic group proceeds significantly faster. Consequently, protonated species +H3N–CH2–COOH can be treated as labile proton donors, whereas zwitterions +H3N–CH2–COO– do not fall into this category.
Modification of polyamide films by semiconductive and conductive copper selenide–copper sulfide layers
Authors: Janickis Vitalijus , Petrašauskienė Neringa
Published: November 2024

Modification of the surface of polyamide 6 (PA) films by semiconductive and electrically conductive layers of mixed copper selenide–copper sulfide, CuxSe–CuyS, was performed using the sorption–diffusion method and the water solutions of potassium selenopentathionate, K2SeS4O6, as the precursor of polymer chalcogeniumization. Selenopentathionate anions containing divalent selenium and sulfur atoms of low oxidation state,–O3S-S-Se-S-SO3–, are sorbed-diffused into PA films if they are treated with selenopentathionate solutions. CuxSe–CuyS layers form on the surface of a PA (polyamide 6) film when a chalcogeniumized polymer is treated with a water solution of copper(II/I) salt: the anions of selenopentathionate react with copper ions. The concentration of sulfur, selenium and copper increases with an increase of the concentration and temperature of a precursor solution and the duration of PA initial chalcogeniumization. The formed layers were characterized for chemical composition, electrical and physical properties. The percentage amounts of selenium, sulfur and copper in CuxSe–CuyS layers on PA films increase with polymer chalcogeniumization time. The X–ray diffraction (XRD) pattern study of CuxSe–CuyS layers showed that they are polycrystalline in nature. The six phases of copper selenides – Cu2Se, CuSe2, CuSe2, Cu3Se2, berzellianite Cu2-xSe and bellidoite Cu2Se, also the four phases of copper sulfides – monoclinic djurleite, Cu1.9375Se, cubic digenite, Cu1.8S, orthorhombic chalcocite, Cu2S, and orthohrombic anilite, Cu1.75S, have been identified. With an increase of the concentration and temperature of the precursor solution and the duration of PA treatment the highest concentration of conductive copper selenides is reached and the composition of CuxSe phases changes in the direction of a decrease of x. XPS results confirmed the formation of copper selenides–copper sulfides layers on the surface of PA. The regularities established enable formation of CuxSe–CuyS layers of the desirable composition and conductivity. Studies by the method of atomic force microscopy (AFM) showed that depending on the conditions (duration of chalcogeniumization, concentration and temperature) of the PA initial treatment in the K2SeS4O6 solution (under the same “copperizing” conditions), the formation of copper chalcogenide layers proceeds irregularly in the form of islands which grow into larger agglomerates. The surface of the layer is uneven, rather rough.

This study aims to analyze human resources in small agricultural enterprises, focusing on identifying factors that influence productivity and business sustainability. The research subjects are small-scale farmers in the Garuda 12 Women's Farming Group in Cipayung, Ciputat, South Tangerang, who own less than 200 m² of agricultural land. The research method used is a qualitative approach involving in-depth interviews and participatory observations. Data were collected from 30 members of the Garuda 12 Women's Farming Group in Cipayung, Ciputat, South Tangerang, using purposive sampling to ensure the selected respondents have high relevance to the research topic. The collected data were analyzed using thematic analysis to identify main themes related to human resources. The results indicate that technical skills, access to training, and time management are key factors influencing the productivity of small-scale farmers. Additionally, support from government and non-governmental organizations in the form of extension services and technical assistance also plays a significant role in improving human resource quality. However, limited capital and access to modern technology remain major challenges. The implications of this research suggest that enhancing human resource quality can be achieved through continuous training programs and better access to resources and technology. This study contributes to the understanding of the importance of human resource development in small agricultural enterprises and can serve as a basis for designing more effective policies to support small-scale farmers

EVALUACIÓN DE LAS INTERACCIONES DEPREDADOR Y PRESA TRAS EL USO DE MUESTRAS FECALES COMO ESTÍMULO SENSORIAL
Authors: Peralta Álvarez Andrea , Hevia Méndez Maria Luisa , Escribano Tortosa Damián
Published: November 2024

This study evaluated the effectiveness of using fecal samples as sensory enrichment in zoos to improve animal welfare and interactions between predators and prey. The main objective was to analyze changes in behavior and stress levels, measured through fecal cortisol, in six different species. An experiment was designed in which fecal samples were exchanged between predators and prey, observing their behavioral and physiological responses. The results indicated an increase in active behavior in predators and an increase in avoidance behaviors and cortisol levels in prey. These findings suggest that sensory stimulation through feces can stimulate natural behaviors in predator but may also induce stress in prey. It is recommended to expand the sample size and species diversity in future studies to validate these results.

El enriquecimiento ambiental es un método común para mejorar el bienestar, fomentando comportamientos naturales y reduciendo estereotipias. Entre los métodos de enriquecimiento sensorial, la estimulación olfatoria es de los más sencillos de usar, pero poco estudiada. Este estudio, realizado en el Parque Zoológico Terra Natura Murcia, evaluó el uso de heces como enriquecimiento sensorial, observando cambios en el comportamiento mediante etogramas y midiendo el cortisol fecal. Se seleccionaron tres especies depredadoras (leones, hienas, leopardos) y tres presas (lémures, colobos, cercopitecos) y se plantearon dos hipótesis: en el caso de los depredadores, se postuló que las heces aumentarían sus comportamientos activos, mientras que en las presas incrementarían los comportamientos de evitación y los niveles de cortisol. Se recolectaron heces de cada grupo y se introdujeron en las praderas según las relaciones depredador-presa. La recolección de muestras fecales y la observación de comportamientos se realizaron antes y después de la introducción de las heces, y los comportamientos fueron registrados por observación focal directa durante 10 minutos, usando etogramas específicos para primates y felinos, y clasificando las conductas en activas, inactivas, agonísticas y estereotipias. Los resultados mostraron un aumento de comportamientos activos en depredadores, como olfateo y exploración, y una disminución de los mismos en las presas. Además, los niveles de cortisol en las presas tendieron a aumentar tras la introducción de las heces, mientras que no hubo diferencias significativas en depredadores.

Published: November 2024

El incremento en la demanda de agua promueve la búsqueda de alternativas que permitan optimizar su uso. Una estrategia es el reuso de aguas residuales domésticas en agricultura; por ello en el presente trabajo se evaluó el efecto de seis productos de limpieza en la germinación y crecimiento de la plántula de Melotria scabra, una planta trepadora cucurbitácea que produce un pequeño fruto ovoide comestible, llamado coloquialmente “sandía de ratón”. Se aplicó la técnica de toxicidad aguda en semillas con 36 semillas por contenedor, en análisis por triplicado.
Bajo las concentraciones evaluadas dentro del intervalo de las recomendadas por el fabricante, cinco productos de limpieza (detergente lavatraste, detergente para ropa en polvo, jabón en barra, limpiador multiuso y shampoo anticaspa) produjeron una disminución significativa en las variables de respuesta evaluadas, germinación, longitud de tallo y la raíz así como el peso de la plántula. El shampoo para cabello normal no provocó efecto en las variables evaluadas. No se recomienda el empleo de aguas residuales domésticas para el riego de esta especie.

Published: November 2024

El liderazgo estratégico situacional es la capacidad integral que tiene un líder para crear y anticipar acciones, gestionar los recursos empresariales y responder a necesidades específicas organizaciones en un contexto determinado, por tanto, el directivo, es el responsable de lograr las acciones previamente planificadas e incorporadas en una visión empresarial. El objetivo principal de este artículo fue determinar si el líder estratégico que predomina en las empresas sociales tiene características situaciones para realizar acciones y tomar decisiones que inciden en la administración de las empresas sociales. Se realizó un estudio tipo cuantitativo, no experimental, transversal y correlacional. La muestra fueron 23 gerentes encargados de la dirección de una asociación no gubernamental sin fines de lucro, ubicada en la ciudad de San Pedro Sula, Cortes. Para la recolección de la información se usó una versión adaptada de Cuestionario Multifactorial de Liderazgo (MLQ) en el año 2018 por Vargas y otros investigadores (1), que a su vez realizaron una adaptación del Cuestionario de Liderazgo Multifactorial (MLQ) utilizada por Guillen en el año 2005 sobre la base del MLQ diseñado en 1997 por Bass y Avolio. El instrumento y su adaptación fue validada por juicio de dos expertos con el grado de Doctor en Administración de Empresas. Los datos se analizaron con la inferencia estadística mediante el software estadístico SPSS versión 22. Los resultados obtenidos revelan que el 95.65% de los dirigentes de la organización no gubernamental participante no han desarrollado las características de líder situación, por su escasa formación académica estratégica y por tanto se concluye que no existe en ellos características de un líder estratégico situacional, por no ser capaz de responder a determinadas contextos empresariales y como consecuencia afectan negativamente la dirección, la planeación y la gestión administrativa, impidiendo el logro de los objetivos previamente planificados.

Published: November 2024

Los incidentes negativos durante el traslado de mercancías son de interés para la gestión de las empresas transportadoras. Estos incidentes se han convertido en un serio problema para la organización, ya que no se tiene un control para la mejora del índice de siniestralidad y por consecuencia se ve afectado el factor humano. La imprudencia, la carga excesiva de trabajo y falta de capacitación de los operadores son los factores identificados en los siniestros (maniobras, cortes de circulación, salidas de carretera, alcances, volcaduras, entre otros). El desarrollo de esta investigación se realizó a través de un estudio cuantitativo de corte longitudinal; en el cual se implementó un programa de capacitación continuo para los operadores involucrados en las terminales más afectadas por los accidentes viales. Asimismo, se adoptó el uso de cámaras con inteligencia artificial para detectar los hábitos de conducción de los operadores. Con base en lo anterior, se generó una base de datos en una plataforma de rastreo que generó alertas en tiempo real para que dieron lugar a acciones de gestión para prevenir la siniestralidad. Mediante esta intervención se redujo el índice de siniestralidad. Se presentan las conclusiones derivadas del estudio y recomendaciones para investigaciones futuras.

Published: November 2024

Age-related macular degeneration (AMD) is one of the leading causes of vision loss in elderly adults around the world and is among the main visual impairments in Mexico. The difficulty of diagnosing AMD in its early stages motivates the use of advanced deep-learning methods that offer significant potential to improve diagnostic accuracy in retinal image analysis. In recent years, Transformer architectures for computer vision, such as Vision Transformer (ViT), Swin Transformer and BERT Pre-training of Image Transformers (BEiT) have provided a novel perspective for image analysis. This study presents a comparative analysis of these architectures, applied to AMD detection, focusing on each model's capability to classify the early stages of the disease. Although the small size of medical image datasets represented a challenge, our results suggest that ViT-based architectures and their derivatives achieve significant performance in AMD detection. BEiT is particularly notable for its consistently superior performance.

The lack of attention to emergency alerts in road accidents in a timely manner may be due to the lack of management of resources or the lack of communication between hospital and patrol departments. The purpose of this research is to reduce the management time to provide attention to requests on highways. An alert and resource management process is proposed. This process will allow sending the optimized information in the shortest possible time. The experimentation was worked with a set of test instances and simulated in the laboratory using mechatronic devices to show the communication, coordination and attention in real time. The results obtained were acceptable, it was possible to identify the alert to be included in the algorithm which must comply with the restrictions and subsequently calculate the optimal route to be followed by the mechatronic device to reach the request node for the attention of the distress alert.

Published: November 2024

This study aimed to confirm whether appraisal and reward significantly affect motivation individually, and whether appraisal significantly affects rewards. X Inc., an automotive manufacturing company in Indonesia, has implemented a suggestion system since 2012. In 2019, the company encouraged employee motivation to participate in the suggestion system through a reward and appraisal programme. The company proposed selecting the Employee of the Month through an appraisal of the best ideas and provided financial rewards to the winner. A survey was conducted at X Inc. to verify the proposed hypotheses regarding appraisal, reward, and employee motivation to participate in the suggestion system. To achieve the aforementioned goal, the study gathered data through interviews and surveys based on the indicators developed based on previous studies’ findings. The data were processed using Structural Equation Modelling (SEM) and showed that appraisal did not significantly affect employee motivation and reward; however, reward significantly affected employee motivation. The practical significance of this study includes recommendations for big enterprises to increase the monthly financial reward for employees who provide the best ideas. Theoretical novelty is the introduction of new indicators of employee motivation and the utilization of the SEM approach for their analysis.

• This systematic review explores the advancements in Natural Language Processing (NLP) for Human-Computer Interaction (HCI) over the period from 2010 to 2024. It highlights the significant breakthroughs achieved through deep learning models, particularly transformer architectures such as BERT and GPT, which have transformed the ability of machines to understand and generate human language. The integration of multimodal capabilities has further enriched user interactions by enabling the processing of diverse data types, including text, audio, and visual inputs. However, the review also identifies persistent challenges, including maintaining coherence in long dialogues, resolving ambiguous language, addressing bias in training data, and the need for resource-efficient models. Additionally, the paper emphasizes the importance of cross-lingual capabilities for low-resource languages and the necessity of personalized, adaptive systems. The findings underscore the need for ongoing research to overcome existing limitations and enhance the effectiveness and inclusivity of NLP technologies in HCI, ultimately contributing to a more intuitive and accessible user experience.
