Platelet clump assessment using the Cellavision peripherical blood application – do we need manual microscopy?
Authors: Janel Alexandre 
Published: February 2025

Abstract

Objectives
This study aims to investigate the frequency, detection, and distribution of platelet clumps, assess the performance of automated digital microscopy (Cellavision) for detecting platelet clumps and explore strategies to optimize detection efficiency.

Methods
We conducted a retrospective analysis of 987,586 hemograms to evaluate the frequency of platelet clumps, and a study of 246 hemograms with platelet clumps for manual and digital microscopic reviews of blood smears. We investigated the locations and sizes of these clumps along the smear, and evaluated the detection capacity of the Cellavision system.

Results
Platelet clumps were found in 0.29 % of cases, with a higher incidence in pediatric and elderly populations. Platelet clumps were more frequent and larger at the smear periphery. Cellavision achieved 93 % sensitivity when combining the leukocyte and red blood cell observation fields. The strategy of reviewing only selected cases (platelet count <50 × 109/L or history of clumps) detected 97 % of platelet clumps, while reducing manual reviews by fourfold.

Conclusions
Automated digital microscopy is an effective tool for detecting platelet clumps, but it requires manual review in specific cases. Expanding image acquisition to the feather edge could further improve detection. A combined approach maximizes efficiency and ensures diagnostic accuracy, particularly in critical cases with low platelet counts.

Abstract

Introduction
Daytime sleepiness in the professional driving industry may affect the safety of drivers at work. Fatigue and obstructive sleep apnoea–hypopnoea syndrome are the most common causes that lead to daytime sleepiness.

Purpose
The aim of this study is to investigate daytime sleepiness as a possible cause of occupational accidents in professional drivers.

Materials and methodology
The Epworth Sleepiness Scale was used to measure sleepiness in 70 professional drivers of different ages, working on both national and international routes. Drivers answered a questionnaire exploring demographic data, as well as an Epworth Sleepiness Scale questionnaire. Data were analysed using the SPSS® Statistical Data Editor 2019 statistical programme, with a 5% level of significance.

Results
Of the studied samples, 50% of the drivers operate on national routes and the other 50% operate on international routes. Nearly half of them (47.1%) work during lunch hours while they rest mostly in the evening. Eight percentage of the drivers suffer from a disease, and 38.6% have 10–15 years of experience. Drivers work an average of 6.91 h and sleep 6.34 h per day, with 37.1% reporting sleeping on the job. The study’s results suggest that there is no statistically significant correlation between sleepiness and the type of route they travel (p-value = 0.142).

Conclusions
Daytime sleepiness is a common cause of road accidents, but this study does not confirm a correlation in specific routes. Although the work involves demanding schedules and routes, Greek professional drivers are perceived as being responsible, focused, and concentrated, which help them to stay alert.

Published: February 2025

Abstract
Tricyclodecyl-containing methacrylate polymers based on tricyclodecyl methacrylate (TCDMA), namely poly (tricyclodecyl methacrylate) [P (TCDMA)] and poly (tricyclodecyl methacrylate-co-methyl methacrylate) [P (TCDMA-co-MMA)], were synthesized by free radical polymerization. Homo- and copolymer were characterized by Fourier transform infrared (FTIR) and 13C NMR spectroscopy. The effects of structural design on the thermal, mechanical, dielectric and optical properties of synthetic polymers were studied. Compared to polymethyl methacrylate (PMMA), the incorporation of a tricycloalkyl substituent as a side group on a methacrylate polymer helps to improve thermal stability, while providing high transparency and long-term heat resistance in the UV–visible region. In addition to improving mechanical properties, the coefficient of thermal expansion (CTE), water absorption and dielectric constant are reduced. These advantages make tricycloalkyl-containing methacrylate polymers promising candidates for use as high value-added optical plastics in optoelectronic applications.

Abstract
Environmental impact evaluation across a product’s complete journey is achieved through Life Cycle Assessment (LCA), a systematic approach that examines each stage from beginning to end. This methodology considers everything from obtaining initial materials to final disposal, including manufacturing processes, distribution networks, consumer usage, and end-of-life handling through recycling or waste management. The goal is to comprehend the overall environmental footprint. Several challenges hinder the adoption of bio-fiber composites in the energy sector, despite their environmental advantages. This chapter identifies key challenges, such as inefficiencies in raw material extraction, high energy consumption during production, and waste management issues during disposal. The objective is to outline the principles of LCA, review recent research, and propose technological and policy solutions to address these challenges. Case studies from various energy sectors are also examined. In conclusion, the chapter emphasizes the significance of ongoing research and development to enhance the lifecycle sustainability of natural fiber composites. The analysis reveals key information that helps drive the shift to environmentally friendly and renewable energy solutions.
Inteligencia artificial generativa y confianza en los medios. Un análisis de la detección de IA en noticias usando GPTzero
Authors: López del Castillo Wilderbeek Francisco Leslie 
Published: February 2025

Introducción: El uso de la IA en la generación de noticias es una realidad que puede poner en peligro la confianza en los medios de comunicación. Metodología: El presente trabajo ha tenido el objetivo de analizar mediante análisis de contenido si la mejor plataforma para la detección de uso de IA en textos: GPTZero, es garantía para discriminar entre noticias elaboradas completamente con IA y contenidos firmados por profesionales. Para ello se analizaron textos de noticias reales (prensa y digital) y de noticias elaboradas por inteligencia artificial (ChatGPT). Resultados: Los resultados obtenidos han indicado que GPTZero ofrece una baja fiabilidad para detectar textos generados con ChatGPT (7,3%) y, que puede señalar como falsos positivos contenidos que no han sido elaborados con inteligencia artificial. Discusión: Los análisis realizados con dos algoritmos diferentes indicaron que GPTZero no descubrió el uso completo de ChatGPT en un corpus de noticias y, de la misma forma, advirtió de cierta probabilidad de uso colaborativo de IA (redacción por un humano con soporte de IA) en noticias que fueron firmadas por periodistas profesionales. Conclusiones: Los resultados obtenidos han generado más dudas que certezas sobre si GPTZero puede ayudar a señalar el uso de IA o asegurar el prestigio de los medios de comunicación.

Представлены результаты выявления пространственно-временных взаимосвязей динамики населения малых городов Западной Сибири во втором десятилетии XXI в. Объектом исследования являются 56 малых городов (с численностью населения до 50 тыс. чел.). Основными источниками статистической информации послужили данные Федеральной службы государственной статистики (Росстата) за период между переписями населения 2010 г. и 2020 г. Выделены пять групп малых городов по изменению численности населения за 2011-2022 гг., дана их характеристика. В среднем для всех малых городов характерно снижение численности населения на 4 %. В большинстве малых городов Западной Сибири численность населения снижается, и только в городах - центрах добычи нефти и газа (Ханты-Мансийский и Ямало-Ненецкий автономные округа) и крупных центрах переработки сельскохозяйственной продукции (Новосибирская область) отмечается положительная динамика. Самой многочисленной (39 %) является группа городов с незначительным снижением численности населения. К настоящему времени в малых городах практически завершилась перестройка структуры хозяйства, поэтому в ближайшие годы, вероятно, сохранится их экономический профиль.
The article presents the results of revealing the spatio-temporal interrelations of the population dynamics of small towns in Western Siberia in the second decade of the 21st century. The object of the study is 56 small towns (with a population of up to 50 thousand people). The main sources of statistical information were data from the Federal State Statistics Service (Rosstat) for the period between the 2010 and 2020 population censuses. Five groups of small towns have been identified according to the population change in 2011-2022, and their characteristics are given. On average, all small towns are characterized by a 4 % decrease in population. In most small towns in Western Siberia, the population is declining, and only in cities that are centers of oil and gas production (Khanty-Mansiysk and Yamalo-Nenets Autonomous Okrugs) and large centers of processing agricultural products (Novosibirsk Oblast) there is a positive trend. The largest (39 %) is the group of cities with a slight decrease in population. By now, the restructuring of the economic structure in small towns has almost been completed, so their economic profile is likely to remain in the coming years.

Освещается значительный вклад В.А. Снытко в изучение перемещения вещества эоловыми процессами в степных и лесостепных геосистемах Сибири. Большое внимание ученый уделял Байкальскому региону. На основе анализа гидротермической обстановки и специальных экспериментов им было установлено, что интенсивность эоловой миграции вещества является отражением климатической ситуации, показателем состояния ландшафтов и степени их техногенной трансформации. В каждом исследуемом ландшафте В.А. Снытко учитывал режим ветров, господствующих в районах активной дефляции и аккумуляции эоловых отложений. Совместно с польскими исследователями им выполнена типизация эоловых урочищ. Установленные морфологические и динамические признаки современной эоловой миграции вещества важны в целях географического прогнозирования. Отмечена большая роль эоловых процессов в пространственной дифференциации вещества. Показано, что антропогенное использование песчаных берегов Байкала привело к их деградации и нарушило ход эоловых процессов. В результате многолетних исследований выявлены особенности трансформации функционирования эоловых геосистем. Отмечено, что все байкальские геосистемы требуют бережного отношения. Результаты исследования отражены в многочисленных статьях, сборниках и монографиях.
The article highlights the significant contribution of V.A. Snytko to the study of matter movement by aeolian processes in the steppe and forest-steppe geosystems of Siberia. The scientist paid much attention to the Baikal region. Based on the analysis of the hydrothermal environment and special experiments, he established that the intensity of aeolian migration of matter is a reflection of the climatic situation, and an indicator of the state of landscapes and the degree of their technogenic transformation. In each studied landscape, V.A. Snytko took into consideration the wind regime prevailing in areas of active deflation and accumulation of aeolian deposits. Together with Polish researchers, he carried out a typification of aeolian tracts. The established morphological and dynamic features of modern aeolian migration of matter are important for the purposes of geographical forecasting. The great role of aeolian processes in the spatial differentiation of matter is noted. It is shown that anthropogenic use of the sandy shores of Lake Baikal led to their degradation and disrupted the course of aeolian processes. As a result of many years of research, the features of the transformation of the functioning of aeolian geosystems have been identified. It has been noted that all Baikal geosystems require careful handling. The results of the research are reported in numerous articles, collections and monographs.
Gamification in Physics Education: Play Your Way to Better Learning
Authors: Richter Katharina , Kickmeier-Rust Michael 
Published: February 2025

This research investigates the effectiveness of gamification in enhancing student engagement, motivation, and learning outcomes in physics education, with a particular emphasis on structural performance modeling through Knowledge Space Theory (KST). The study utilizes Basketball Physics Challenge - a game designed to teach fundamental physics concepts like initial velocity, motion, and trajectory - and compares the outcomes of gamified versus non-gamified learning environments. The experimental design involved 10th grade students from a secondary school in Liechtenstein, using a crossover methodology where participants alternated between gamified and non-gamified versions of the game. The results indicate that gamification significantly boosts engagement and performance metrics, as evidenced by increased time on task, a higher frequency of attempts, and better scores compared to the non-gamified condition. Additionally, gamification positively influences motivation, particularly when experienced before non-gamified sessions. Although quiz performance did not show significant differences between conditions, a strong positive correlation was observed between game scores and quiz points in the gamified condition during the second session. The study, furthermore, analyzed structural performance and learning trajectories, demonstrating that gamification fosters a more dynamic and effective learning process. This study highlights the potential of gamification to transform physics education by enhancing student motivation and engagement, thereby promoting a deeper understanding and retention of complex scientific concepts.
Psychometric properties of the Self-Care Inventory for Children with Cerebral Palsy in a resource-constrained urban South African Context
Authors: Seward Caroline , Franzsen Denise 
Published: February 2025

Introduction: For children with cerebral palsy (CP), conducting self-care tasks may be difficult due to physical and cognitive problems. Accurate assessment of children with CP is needed for realistic intervention. The Self-Care Inventory for Children with Cerebral Palsy (SCICP) was developed by Julia Burg in 2016. The SCICP is a caregiver reported questionnaire that aims to assess the extent to which a CP child can conduct their self-care tasks independently. Burg created the SCICP due to the lack of a valid assessment tool for the South African population to assess CP children's self-care abilities. The aim of the study was to investigate selected psychometric properties of the SCICP in terms of known-group validity, concurrent validity with the gross motor function, and manual abilities of the children with CP as well as the tool's diagnostic accuracy.Method: A quantitative cross-sectional, non-experimental study design with the caregivers of 50 children with CP (0 to 8-years-old), and 50 typically developing children (0 to 6-years-old) was conducted. Data were collected at two hospitals in the Ekurhuleni district in Gauteng, South Africa. The caregivers completed a demographic questionnaire and the SCICP assessment tool for each child. Descriptive statistics and non-parametric statistics including the Mann- Whitney U test as well as Spearman's correlation co-efficient were used to analyse the data, since data were ordinal. Sensitivity andÂ specificity and internal consistency were also established.Results: The SCICP differentiates between children who are typically developing and children with CP who present with developmental delay on the overall score. For some components of self-care activities for the 0 to 1-year-old children, the difference in scores is not significant since typically developing children of this age may be dependent in many self-care tasks.Conclusion: The SCICP shows promising results for use in the clinical setting to identify deficits in CP children's ability to perform their self-care tasks and provide guidance for intervention for self-care for children with CP.Keywords: cerebral palsy; resource-constrained environment; self-care; participation; evaluation; known-group validity; functional mobility; low socio-economic status

Authors: Van Biljon Hester , Van Niekerk Lana 
Published: February 2025

Introduction: Older adults with limited socio-economic means, living in South Africa's most densely populated province, Gauteng, have experienced historical restriction and challenges to their freedom of movement. Interviews were conducted with older adults attending public healthcare facilities that offered rehabilitation service in Gauteng, to capture their community mobility experience and the modes of transport they used. These interviews explored the difficulties the older adults experienced and the strategies they employed to overcome them, with an invitation for them to give suggestions for improvement.Â Method: An exploratory concurrent mixed methods study design saw 84 rehabilitation clinicians, interview 393 older adults visiting public healthcare facilities where the clinicians practiced. Clinicians kept 109 field notes and took part in a cumulative five hours of discussion. Quantitative data were analysed using descriptive statistics and qualitative data through inductive content analysis.Â Results: Walking and mini-bus taxis were the most prominent forms of community mobility. Fiscal and transport poverty, crime and poor infrastructure were barriers participants experienced.Â Community involvement and leadership accountability were suggested solutions.Â Conclusion: Involving stakeholders themselves in conceptualising and applying solutions to challenges is an acknowledged approach within the collectivist paradigm. The community mobility and transport use realities of older adults, and the rehabilitation professionals who interviewed them, as well as the existing strategies and suggestions they gave to overcome the barriers they experienced should be taken note of by policy makers and service providers. The presentation of these is to stimulate further consideration and development.Â Key words: transport poverty; limited socio-economic means; community involvement; leadership accountability; stake holders, ubuntu

Authors: Lopes Correia Ricardo , Wertheimer Luciana , Morrison Rodolfo , Silva Carla Regina 
Published: February 2025

Background: The contemporary perspectives of occupational therapy in Latin America focus on an epistemic, political, and plural field under construction and in dispute. It is about the notions of knowing and doing designed to appoint the theoretical and methodological aspects that support the reading and intervention of the complex realities.Purpose: This paper explores a glocal dialogue about the production and dissemination of knowledge in occupational therapy in Latin America.Key Issues: The dialogue includes issues and trends in the global scientific and social scenario, without neglecting aspects of different local realities around the world. By focusing on the profession in Latin America, using different perspectives, such as Critical Occupational Therapy; Occupational Therapy and Social Issues; Occupational Therapy and Culture; Territory and Community Occupational Therapy; Southern Occupational Therapies; and Occupational Science in Latin America. It further discusses the relationship between the theoretical perspectives and the coloniality of knowledge in occupational therapy and the contradictions based on neoliberal models in the production and dissemination of knowledge.Conclusion: The hegemonic neoliberal model and the glocalisation theoretical framework appeared to support and circumvent the production of scientific knowledge in occupational therapy, and placed Latin America on the periphery of the global debate.Â Keywords: professional practice of occupational therapy; theoretical framework, theoretical perspective, coloniality of knowledge, critical occupational therapy, occupational science.Â

Introduction. Visualization of oral movements and facial expressions is essential for learning, development, and communication, especially among students receiving speech and language services. This study aimed to assess the effectiveness of cloth masks with transparent windows as an alternative to opaque masks in mitigating the risk of droplet-transmitted infectious diseases.
Methods. Researchers measured the filtration efficiency of various medical and non-medical masks, both with and without transparent windows. A testing pipe, fitted with the selected masks, was used to deliver particulate matter (PM) at an airflow velocity mimicking human breathing. Particle size and airflow were measured using three real-time particle monitors positioned upstream and downstream of the masks. Filtration efficiency was then calculated for each of the eight masks.
Results. Mask efficiency varied based on build quality and material. Filtration efficiency for the four face masks with transparent windows ranged from 28.6% to 90%, with the single-layer mask performing the worst. All multi-layer masks with windows achieved filtration efficiencies greater than 70% for all particle sizes tested (1, 2.5, and 10 microns), exceeding that of the opaque cotton masks and approaching the filtration levels of surgical masks.
Conclusions. Given the high filtration efficiency of cloth masks with transparent windows, the authors conclude that these masks can reduce the transmission of SARS-CoV-2 and other droplet-transmitted infectious diseases while also improving communication for individuals with speech, language, and/or hearing impairments.
