Advances and Challenges in the Use of Biomechanics-Inspired Digital Technologies for Managing Pediatric Chronic Diseases: A Systematic
Full text linkThis study aims to systematically review biomechanics-inspired digital technologies applied in the management of pediatric chronic diseases, focusing on their effectiveness, limitations, and implementation challenges.Following PRISMA 2020 guidelines, a comprehensive search was conducted in Web of Science, Scopus, and Google Scholar. Studies were included if they addressed pediatric patients (0–18 years) and involved digital health interventions integrating biomechanical data or telemedicine solutions. A total of 20 peer-reviewed studies were selected after screening 368 records. Data extraction included study design, technologies, health outcomes, and implementation barriers. mHealth platforms demonstrated treatment adherence rates up to 80% in cystic fibrosis, while therapeutic video games improved quality of life and psychological well-being in pediatric cancer patients. Telemedicine significantly reduced hospitalization and improved follow-up attendance, particularly in diabetes and asthma cases. Advanced technologies, such as wearable motion sensors, robotic exoskeletons, and continuous glucose monitoring, enhanced rehabilitation outcomes and personalized treatment. Despite these benefits, barriers included high development costs, limited digital literacy, infrastructure gaps, and ethical concerns related to data privacy.Biomechanics-inspired digital technologies significantly enhance adherence, rehabilitation, and quality of life for children with chronic illnesses. However, widespread implementation requires addressing structural barriers, ensuring equitable access, and integrating culturally sensitive solutions. Future research should focus on adaptive tools, long-term evaluations, and strategies to bridge technological and socioeconomic gaps in pediatric healthcare

Impact of School Violence and School Climate on Victimization and Perpetration in Adolescent Bullying and Cyberbullying
Full text linkIntroduction: bullying and cyberbullying are systematic forms of school violence that significantly impact students’ psychosocial well-being and the overall institutional climate. Beyond individual-level factors, certain contextual dynamics—such as low-intensity recurrent violence and a deteriorated school climate—may facilitate the emergence and persistence of these behaviors. Objective: to examine the complex interactions among school violence, school climate, and the roles of victimization and aggression involved in bullying and cyberbullying among adolescents. Method: a sample of 200 adolescents from a public school in Medellín, Colombia, was assessed to examine behaviors related to bullying and cyberbullying, as well as perceptions of school climate and institutional violence. Four validated questionnaires were administered to measure victimization, aggression, school climate, and school violence across multiple dimensions. Data analysis involved exploratory factor analysis and structural equation modeling with corrections for non-normality. Model validity and reliability were evaluated using multiple goodness-of-fit indices. Results: school violence showed a weak negative effect on school climate and a weak positive effect on both aggression and victimization roles in bullying and cyberbullying; school climate had a significant effect only on the aggression role in traditional bullying; and school climate did not mediate the relationship between school violence and the aggression or victimization roles in either bullying or cyberbullying. Conclusion: the findings suggest that while school climate is modestly linked to aggression in traditional bullying, it does not act as a mediating factor in the broader relationship between school violence and the dynamics of bullying and cyberbullying. These results underscore the importance of addressing contextual risk factors in comprehensive violence prevention strategies within school settings
Productive performance of laying quails fed diets supplemented with Morinda citrifolia (noni) leaf meal
Full text linkIntroduction: quail production in Latin America has experienced significant growth due to its hardiness, prolificacy, and low maintenance costs, making the rearing of these birds a competitive alternative for egg production. In this context, phytobiotics have gained relevance in the animal feed industry, as they represent a sustainable strategy to improve productive efficiency and reduce dependence on synthetic additives.
The objective of the present study was to evaluate the productive performance of laying quails supplemented with Morinda citrifolia (noni) leaf meal in their diet.
Method: the study was conducted over 45 days under a completely randomized design (CRD), which included four treatments, five replicates, and a total of 140 laying quails. The treatments consisted of different inclusion levels of Morinda citrifolia leaf meal: 0 % (T4), 0,5 % (T1), 1,0 % (T2), and 1,5 % (T3). Productive performance variables were evaluated, mainly laying percentage and economic profitability.
Results: supplementation with Morinda citrifolia leaf meal did not exert significant effects on the productive performance of laying quails. No statistical differences were observed in laying percentage among treatments; however, week 6 showed the highest laying rate and persistence, reaching 74,40 %. In economic terms, treatment T2 (1,0 % noni leaf meal) yielded the best results, with a profitability of 45,5 % and a benefit/cost ratio of 0,45 was obtained.
Conclusions: The inclusion of Morinda citrifolia leaf meal in the diet of laying quails did not significantly affect productive performance. Nevertheless, supplementation at 1,0 % stood out as the most profitable alternative, highlighting its potential as a phytobiotic feed additive in quail production. These findings contribute to the development of sustainable nutritional strategies in poultry farming, enhancing the competitiveness and profitability of low-cost production systems
Impact of Anhydrous Alcohol as a Complementary Fuel on Gasoline Engine Performance and Efficiency
Full text linkIntroduction: The growing interest in preserving the environment has driven the search for cleaner energy sources, including biofuels such as anhydrous alcohol, which can reduce the environmental impact of fossil fuel use without affecting engine performance. This project aimed to analyze the behavior of a gasoline engine when using anhydrous alcohol as a fuel additive.Objective: This study evaluates the effects of anhydrous alcohol–gasoline blends (E5, E10, E15, and E20) on the mechanical performance and pollutant emissions of a Chevrolet Aveo 1.6 L spark-ignition engine under different test conditions.Methods: The study was conducted on a Chevrolet Aveo vehicle equipped with an electronic injection system and a 1600 cc engine, evaluating its mechanical performance and emissions. Static tests, dynamic road tests, and laboratory analyses were carried out using conventional gasoline and blends containing 5%, 10%, 15%, and 20% anhydrous alcohol. Parameters such as power, torque, and emission levels were measured following the INEN 2204:2002 and 2203:99 standards.Results: The results showed that the incorporation of anhydrous alcohol did not produce significant variations in power or torque but did reduce CO, HC, and CO₂ emissions, although with a slight increase in NOx, remaining within the established limits.Conclusions: Anhydrous alcohol–gasoline blends up to 20% (v/v) can be used in conventional engines without performance penalties, while contributing to reductions in CO, HC, and CO₂ emissions. The trade-off is a moderate increase in NOx, which must be considered in emission control strategies. These findings support the potential of alcohol as a transitional fuel in urban transport under Latin American regulatory frameworks
