Automatic recognition of sign language from hand gesture images is crucial for enhancing human-robot interaction, especially in critical scenarios such as rescue operations. In this study, we employed a DJI TELLO drone equipped with advanced machine vision capabilities to recognize and classify sign language gestures accurately. We developed an experimental setup where the drone, integrated with state-of-the-art radio control systems and machine vision techniques, navigated through simulated disaster environments to interact with human subjects using sign language. Data collection involved capturing various hand gestures under various environmental conditions to train and validate our recognition algorithms, including implementing YOLO V5 alongside Python libraries with OpenCV. This setup enabled precise hand and body detection, allowing the drone to navigate and interact effectively. We assessed the system's performance by its ability to accurately recognize gestures in both controlled and complex, cluttered backgrounds. Additionally, we developed robust debris and damage-resistant shielding mechanisms to safeguard the drone's integrity. Our drone fleet also established a resilient communication network via Wi-Fi, ensuring uninterrupted data transmission even with connectivity disruptions. These findings underscore the potential of AI-driven drones to engage in natural conversational interactions with humans, thereby providing vital information to assist decision-making processes during emergencies. In conclusion, our approach promises to revolutionize the efficacy of rescue operations by facilitating rapid and accurate communication of critical information to rescue teams.

The Connection between Sleeping Disorders Among Students and Academic Success
Authors: El Mourtada Adel , Degmečić Dunja
Published: February 2025

Aim of the study: Objective of this research was to examine whether sleep disturbances affect the academic success of students of the Faculty of Medicine in Osijek.Methods: The respondents conducted a self-assessment using a sociodemographic questionnaire and the Pittsburgh Sleep Quality Index (PSQI).Results: It is observed that there is no significant correlation between age, overall academic success and months of work (if the respondents were employed) with the sleep quality index. Respondents from lower years of studies have a higher sleep quality index, therefore worse sleep quality compared to higher years respondents, whereas daily average studying time has proportional values to the PSQI sleep quality index. In other words, the more hours they spend studying, the higher the sleep quality index. Therefore, the quality of sleep is lower. There are no significant differences in the PSQI sleep quality index in relation to the general characteristics, except in the case of treatment by a psychiatrist. Subjects who were treated by a psychiatrist had significantly worse sleep quality compared to other subjects.Conclusion: There is no significant correlation between sleep disorders and academic success among students. Subjects from lower years of study had higher values ​​of the PSQI and their sleep quality was inversely proportional to the time they spent studying. Subjects who had a psychiatric diagnosis had worse quality of sleep.
First principles study of molecular hydrogen activation by defects in boron nitride
Authors: Sassi Michel , Autrey Tom
Published: February 2025

We used density functional theory simulations in combination with ab initio thermodynamics to determine the H2 partial pressure (p_("H" _"2" )) dependent energetics associated with H2 activation and recovery at various defect sites in hexagonal boron nitride (h-BN). We found that some defects are very reactive with hydrogen thereby definitely trapping hydrogen in defective h-BN. However, depending on hydrogen partial pressure, less reactive defect sites can be populated. Because of the lower binding capability of these sites, they would allow for hydrogen to be recycled and recovered. For small defect sizes, we found that hydrogen preferentially bind to nitrogen sites by forming N—H bonds, and if no N sites are available then boron sites would be the next to bind hydrogen. Hydrogen dissociation via Frustrated Lewis Pair (FLP) is found to be more favorable than forming only N—H bonds but only if the defect size is large enough to accommodate steric effects. For specific conditions such as T= 400 K, p_("H" _"2" )=1 bar, and only considering one molecular H2 per defect, three defects, namely the N monovacancy, 3V(1B2N), and hexagonal 6V(3B3N) could play a role in both the activation and recycling of H2, as they would be reacting enough to allow a favorable splitting of H2 while not binding too strongly to allow its recovery. More broadly, a range of p_("H" _"2" ) and hydrogen loading conditions were investigated for different types of defects and the finding suggests that p_("H" _"2" ) could be used to fine tune the Gibbs free energy of hydrogenation, thereby allowing several types of defects at different hydrogen loading content to play a role in the activation/recovery process of H2 in defective h-BN.

Authors: Pilkington Rowan , Koessler Rosa , Molloy Jesse , Braese Stefan , Priebbenow Daniel
Published: February 2025

Siloxycarbenes induced via the visible light irradiation of acylsilanes undergo highly efficient “photo-click” chemistry reactions with electron deficient ketones. This process requires no reagents other than visible light, proceeds with high efficiency and is tolerant of a wide range of functional groups. Pyruvate esters, thioesters, amides, nitriles and phosphonates were all suitable electrophiles including those tethered to complex drug or biomolecule scaffolds. The “photo-click” chemistry process was achieved on larger scale using both batch and flow methodologies, accompanied by diversification studies on the corresponding addition products. Mechanistic insights into siloxycarbene reactivity were also obtained by DFT analysis.

Authors: Matsuyama Takehiro , Yatabe Takafumi , Yamaguchi Kazuya
Published: February 2025

Catalytic molecular transformations via C(sp3)–S bond cleavage have been rarely explored compared with those via C(sp2)–S bond cleavage despite their synthetic utilities. Here, we have developed alkyl–aryl exchange of thioethers via catalytic non-radical cleavage of inert C(sp3)–S bonds by utilizing a supported Au–Pd alloy nanoparticle catalyst. Based on various control experiments, the C(sp3)–S bond cleavage was revealed to undergo starting from β-hydride elimination, thereby enabling the use of a wide range of alkyl groups differently from previous reports involving C(sp3)–S bond oxidative addition.

3D printing of conductive structures via fused deposition modelling has emerged as a mainstream manufacturing technique for electrochemical devices owing to the affordability and availability of thermoplastic-carbon-based filaments. On the current market, the existing filaments are limited in terms of their electrical conductivity and functionality. To address this, the development of multi-material filaments incorporating additional functional materials along with conductive carbons strategically produces 3D-printed electrodes with enhanced functionalities. In parallel, filament fabrication allows for precise control over the material composition and properties, such as chemical, thermal, and mechanical properties of the filament. In this work, we explored the fabrication of a multi-material filament combining photocatalytic carbon nitride, C3N4, and conductive carbon nanotubes, CNTs. Our C3N4-CNTs electrodes 3D-printed from it outperformed CNTs electrodes in hydrogen evolution and photocatalytic degradation of an organic dye. Our findings suggest that multi-material filaments may transcend the current filament-extrusion printing technique and expand its potential beyond electrochemistry.
“Casi tuve que aprender a ser colombiano de nuevo”. Entrevista a Santiago Gamboa, escritor y periodista colombiano
Authors: Rabí Do Carmo Alonso
Published: February 2025

Tendría que comenzar diciendo que esta es una entrevista que le debe todo al azar, a la amistad de Lucho Rodríguez Pastor y a la buena disposición del entrevistado, que aceptó conversar de buenas a primeras con un desconocido. Es diciembre de 2023, penúltimo día de la feria Ricardo Palma en el parque Kennedy, y yo estoy en medio de un corredor abarrotado esquivando lectores, libreros y, aunque no lo puedo demostrar, algún pájaro frutero con ansias de leer. En medio del gentío me topo con Lucho, que prácticamente trae del brazo a Santiago Gamboa y un poco a la carrera me lo presenta y le indica que soy periodista (el rostro del escritor está impávido) y que debería concederme una entrevista, cosa que pedí de inmediato. “Fíjate —me dijo— que tengo una mesa mañana de 3 a 4, podemos encontrarnos cuando eso termine y conversamos”. La contundente amabilidad de Gamboa me hizo intuir que no era una salida de ocasión ni era tampoco una evasiva. Al día siguiente acudí a la cita y escuché con atención las intervenciones del colombiano sobre la violencia. Terminada la actividad, algunas personas se acercaron a pedir una dedicatoria. Finalmente, me dice: “Vamos al Café de la Paz”. En el trayecto, le recuerdo que el primer libro suyo que leí fue Perder es cuestión de método, esa suerte de tragicomedia colombiana. Sonríe y recuerda algunas cosas de ese tiempo de exilio. Sentado ya uno frente al otro, enciendo la grabadora.

Perceived Research Competence Among Master’s Students in Pre-Service Teacher Education Programmes
Authors: Matjašič Miha , Vogrinc Janez
Published: February 2025

This paper investigates the perceived research competence of students at the beginning of their master’s studies in pre-service teacher education programmes at various higher education institutions in Slovenia. Addressing the absence of suitable measurement tools, we developed and validated a Slovenian-language instrument specifically designed to assess research competence among pre-service teachers. Using this instrument, we were able to compare the perceptions of master’s students with a prior bachelor’s degree in education to those without such a degree. The results show that master’s students perceive strong abilities in formulating research objectives, hypotheses and theoretical substantiation, but lack confidence in statistical procedures and using statistical analysis tools such as SPSS. They also feel unprepared to assess the validity and reliability of data collection instruments and to conduct action research. Furthermore, students without a bachelor’s degree in education perceive better knowledge in research areas and exhibit higher confidence in most statistical and methodological aspects. On the other hand, students with a bachelor’s degree in education demonstrate greater confidence in specialised areas such as statistical procedures and action research, and hold more positive attitudes towards the practical application of research in educational settings. Based on these findings, the paper suggests enhancing hands-on research experiences and fostering a supportive community to improve engagement, confidence and research competence among pre-service teachers.

GIS based allowable bearing capacity thematic maps of shallow foundation for Bogura District, Bangladesh
Authors: Rahman Md Mahabub
Published: February 2025

This investigation aims to create thematic maps of the allowable load-bearing capacity (BC) of shallow footings based on the findings of standard penetration tests (SPTs) carried out in Bogura District. Structural engineers utilize the allowable soil BC to calculate the required dimensions of the shallow footing for the buildings they want to build. 255 boreholes (BHs) were drilled in the research region, which were dispersed randomly. Four SPTs were conducted in each borehole at depths of 1.5, 3, 6, and 9 m, measured from the current ground level (EGL). To assess the accurate SPT-N values, a variety of criteria were taken into consideration, including the unit weight, the groundwater table (GWT), and other correction factors. The allowed soil BC at 1.5, 3, 6, and 9 meters was then estimated using the adjusted SPT-N values. The final product is a set of themed GIS maps of the city, each hue representing a different number for the permissible soil holding capacity. Since clay is present at shallow depths, the allowable BC in 86.5% of the region at 1.5 m depth was less than 73.13 kN/m2, and in 82.4% of the area at 3 m depth, it was between 64.38 and 96.31 kN/m2. For the whole area, the predicted permissible BC for depths of 6 and 9 meters was greater than 100 kN/m2. Various local authorities can use these maps to determine the appropriate type of foundation and forecast the soil carrying capacity. It may also be used to evaluate the likelihood of failure and collapse as well as the foundations of both existing and poorly designed buildings.

Abstract
The food enzyme bacillolysin (EC 3.4.24.28) is produced with the genetically modified Bacillus amyloliquefaciens strain NPR by DSM Food Specialties B.V. The production strain meets the requirements for the qualified presumption of safety (QPS) status. The genetic modifications do not give rise to safety concerns. The food enzyme was considered free from viable cells of the production organism and its DNA. The food enzyme is intended to be used in 10 food manufacturing processes. Since residual amounts of food enzyme‐total organic solids (TOS) are removed in one process, dietary exposure was calculated only for the remaining nine food manufacturing processes. It was estimated to be up to 6.450 mg TOS/kg body weight per day in European populations. Given the QPS status of the production strain and the absence of concerns resulting from the food enzyme manufacturing process, toxicity tests were considered unnecessary by the Panel. A search for the homology of the amino acid sequence of the bacillolysin to known allergens was made and no match was found. The Panel considered that the risk of allergic reactions upon dietary exposure to the food enzyme cannot be excluded, but the likelihood is low. Based on the data provided, the Panel concluded that this food enzyme does not give rise to safety concerns, under the intended conditions of use.

Abstract
The food enzyme non‐reducing end α‐l‐arabinofuranosidase (α‐l‐arabinofuranoside non‐reducing end‐α‐l‐arabinofuranosidase; EC 3.2.1.55) is produced with the non‐genetically modified Aspergillus tubingensis strain ARF by DSM Food Specialties B.V. The food enzyme was free from viable cells of the production organism. The food enzyme is intended to be used in five food manufacturing processes. Dietary exposure to the food enzyme–total organic solids (TOS) was estimated to be up to 0.455 mg TOS/kg body weight (bw) per day in European populations. Genotoxicity tests did not indicate a safety concern. The systemic toxicity was assessed by means of a repeated dose 90‐day oral toxicity study in rats. The Panel identified a no observed adverse effect level of 234 mg TOS/kg bw per day, the highest dose tested, which when compared with the estimated dietary exposure, results in a margin of exposure of at least 514. A search for the homology of the amino acid sequences of the non‐reducing end α‐l‐arabinofuranosidase to known allergens was made and no match was found. The Panel considered that a risk of allergic reactions upon dietary exposure to the food enzyme cannot be excluded, but the likelihood is low. Based on the data provided, the Panel concluded that this food enzyme does not give rise to safety concerns, under the intended conditions of use.

Ethics has become an increasingly emphasized issue in recent years. Ethical decision-making is an action needed in both social and work life. One of the most critical issues in the professional life of accounting professionals is making ethical decisions. This study aimed to examine (i) the ethical decision-making levels of professional accountants and (ii) the impact of affective commitment, whistleblowing, and turnover intention on the ethical decision-making levels of accounting professionals. In this context, quantitative research was conducted with the participation of 147 professional accountants working in Sakarya. Frequency analysis, exploratory factor analysis, internal consistency test, descriptive statistics, independent samples T-Test, Hedge's g test, correlation, and multiple regression analysis were used to analyze the data. According to the findings, the ethical decision-making levels of professional accountants were pretty high. Ethical decision-making was positively associated with affective commitment and external whistleblowing. Female accountants' levels of ethical decision-making, external whistleblowing, and affective commitment to the organization were significantly higher than their male colleagues. In the multiple regression analysis, external whistleblowing and affective commitment positively affected ethical decision-making, while no action in whistleblowing had a negative effect. The research findings were discussed, and some suggestions were provided for further study in the field.

Published: February 2025

Corporate growth is a natural consequence of management's wealth maximization efforts. However, its effects on profitability are not fully understood. This study examines the size-profitability relationship using quarterly data from publicly listed Turkish firms. The findings indicate that size is positively correlated with profitability. However, this relationship is not linear. After reaching a certain point in size, the marginal return becomes negative, raising questions about growth-related decisions. The findings are robust to alternative econometric methods (GMM and FE-OLS), alternative measures of size, and alternative specifications of nonlinearity.

Published: February 2025

La cerveza es considerada un producto microbiológicamente estable debido a sus características fisicoquímicas, sin embargo, algunos grupos de bacterias tienen la capacidad de desarrollarse aún en las condiciones que presenta este medio, causando deterioro del producto y a la vez grandes pérdidas económicas. Los sistemas de dispensación de barril son una potencial fuente de contaminación, ya que, al no realizar una apropiada sanitización de los componentes pueden llegar a formarse películas bacterianas provocando que el producto final se contamine y termine por deteriorarse. Para este proyecto se analizaron 42 muestras de diferentes estilos de cervezas artesanales dispensadas de barril de distintos establecimientos dentro de la Zona Metropolitana de Monterrey, de las cuales 31 tuvieron presencia de bacterias ácido lácticas. Los resultados del análisis de correlación entre los parámetros IBU, ABV, SRM y pH de cada cerveza y la presencia de estos microorganismos, indicaron que no se encontró una relación significativa entre estas variables bajo las condiciones de muestreo.

Hal ini turut menjadi problematika yang dihadapi oleh warga masyarakat Putat Jaya Barat, Surabaya. Terlepas dari prevalensi stunting yang telah mengalami penurunan menjadi 21,6% di tahun 2022, masyarakat Surabaya masih perlu meningkatkan kewaspadaan diri untuk mencegah terjadinya stunting pada anggota keluarga. Oleh sebab itu perlu dilakukan upaya pengabdian masyarakat dalam bentuk pengenalan produk diversifikasi ikan berupa isolat protein yang dapat mencegah fenomena stunting. Isolat protein sebagai bahan pangan fungsional mengandung protein terkonsentrat sehingga dapat memenuhi kebutuhan protein harian. Pelaksanaan kegiatan ini dilaksanakan dengan metode penyuluhan pemberian informasi tentang stunting, diversifikasi produk perikanan, dan demonstrasi pembuatan isolat protein ikan. Hasil kegiatan menunjukkan bahwa pengetahuan teoritis partisipan terkait stunting cukup memprihatinkan, akan tetapi partisipan tanpa disadari sudah mengetahui langkah pencegahan stunting dengan melakukan pemenuhan gizi keluarga secara tepat sesuai konsep 4 sehat 5 sempurna. Partisipan juga mendapat pemahaman terkait metode diversifikasi produk perikanan. Evaluasi kuesioner menunjukkan bahwa partisipan memerlukan penyuluhan lebih lanjut dalam pengolahan produk perikanan menggunakan isolat protein, beserta rancangan gizi ikani, dan penyuluhan hidup sehat.

Kelompok Tani Hutan (KTH) Sejahtera didirikan untuk meningkatkan kesejahteraan masyarakat di Desa Kretek, Kecamatan Taman Krocok, Kabupaten Bondowoso. KTH ini mengelola lahan kopi robusta dengan produksi tahunan 500-800 kg. Namun, selama 11 tahun, lahan ini tidak dipupuk, menyebabkan penurunan produktivitas tanah dan kualitas biji kopi. Untuk mengatasi hal tersebut, teknologi pirolisis diperkenalkan guna memanfaatkan limbah kulit kopi. Teknologi ini menghasilkan biochar  yang dapat meningkatkan kesuburan tanah, mengikat zat pencemar, serta mengurangi emisi gas rumah kaca. Teknologi ini juga menghasilkan asap cair yang dapat dimanfaatkan sebagai antimikroba dan bahan pengawet makanan. Tujuan kegiatan ini adalah membantu masyarakat memanfaatkan limbah kulit kopi menjadi produk unggulan. Metode yang digunakan adalah participatory rural appraisal, yang meliputi introduksi inovasi pemanfaatan limbah kulit kopi menjadi biochar dan asap cair, perancangan dan pembuatan alat, serta praktik penggunaannya dengan melibatkan anggota KTH Sejahtera. Hasil kegiatan pengabdian ini menunjukkan terjadinya peningkatan pengetahuan serta ketrampilan kelompok tani hutan dalam pembuatan biochar dan asap cair menggunakan teknologi pirolisis dari semula rata-rata 30% menjadi 90%. Secara keseluruhan, program pengabdian ini dapat meningkatkan semangat dalam pemanfaatan limbah kulit kopi dan meningkatkan kekompakan KTH Sejahtera.

Capítulo 01 - A LINGUAGEM EM PERSPECTIVA DISCURSIVA: ideologia e produção de sentidos na análise de discurso
Authors: Brito Nayara Alves Silva Mendes Vilela de Sousa
Published: February 2025

A Análise de Discurso (AD) é uma abordagem teórico-metodológica que estuda a linguagem em sua relação com poder, identidade, ideologia e cultura. Investigando como os discursos são construídos e influenciam a produção de sentidos, a AD transcende análises gramaticais, considerando contextos sociais, políticos e históricos. A linguagem é vista como mediação transformadora, com ênfase em sua historicidade e exterioridade. Influenciada por Michel Pêcheux, a AD adota uma perspectiva materialista, explorando a relação entre linguagem, inconsciente e história, e destacando o interdiscurso (memória discursiva) como central na formação de sentidos. A AD analisa textos diversos, incluindo políticos, literários e midiáticos, identificando irregularidades discursivas e suas conexões com contextos ideológicos. A noção de "texto" é ampla, abrangendo palavras, imagens e símbolos como unidades de significação. Em síntese, a AD é uma ferramenta crítica para desvendar mecanismos discursivos, revelando dimensões políticas e históricas na linguagem e reforçando seu papel como mediação dinâmica nas interações humanas.

O trabalho tem por tema ‘Representação e linguagem cinematográfica' onde se pretende fazer uma análise sobre a visão da criança que é apresentada por meio de filmes ou longa metragens. O objetivo deste trabalho é analisar como a linguagem cinematográfica, a partir de todas as suas peculiaridades, apresenta a visão que a criança tem de seu mundo, seja na família, na escola e outros ambientes que ela frequenta. Assim podemos pensar a problemática da construção da subjetividade do sujeito enquanto criança a partir das suas experiências e concepções de mundo. Esta pesquisa se justifica diante do interesse científico de enfrentar os processos de construção de mundo que o sujeito desenvolve nos seus primeiros anos de vida. A metodologia utilizada para desenvolver esse trabalho foi a de análise de filmes e pesquisas bibliográficas.

Este artigo analisa os contos “Andorinha” e “Causa perdida”, presentes em Histórias de bichos, de Luiz Vilela. Nestes contos são apresentadas relações de personagens seres humanos e animais. Por meio dessas relações problematizamos se o escritor estaria discutindo concepções de animalidade e humanidade. Para desenvolver este estudo, nos pautamos em estudiosos que se propuseram a pensar e escrever sobre o trabalho de Vilela e as relações entre personagens seres humanos e animais na literatura. Abordaremos temas como maus-tratos aos animais, compaixão, morte, o desaparecimento de personagens animais e alteridade.
