A review of IoT-Enabled Intelligent Smart Energy Management for Photovoltaic Power Forecasting and Generation
(KeAi chinese roots global impact, 2025-11-09) Rao, Challa Krishna; Sahoo, Sarat Kumar; Yanine, Fernando
Renewable energy has emerged as one of the most reliable and widely accepted approaches to address the rising global energy requirements. Among these, solar power development requires focused attention on both maintenance strategies and application methods. To enhance solar energy utilization, Internet of Things (IoT)-enabled monitoring frameworks have been designed, allowing real-time collection and analysis of solar parameters for predicting efficiency and ensuring stable electricity generation. A major concern in demand-side energy regulation lies in utilizing renewable sources effectively while keeping costs manageable and minimizing unnecessary consumption. Hence, careful planning of renewable resource integration is essential. Advanced energy management platforms play a crucial role in supervising energy distribution, especially in scenarios where heavy dependence on the grid exists. The complexities and opportunities introduced by expanding grid networks can be efficiently managed through cloud-based technologies. This work emphasizes the practical application of energy management systems in both industrial operations and academic research, treating them as key stakeholders in the energy sector. The investigation offers a detailed evaluation of IoT applications in photovoltaic power systems and highlights the promising future avenues available to researchers. These include developing new benchmarks to measure IoT performance and refining existing systems through innovative approaches. Furthermore, there is an increasing demand for comprehensive studies on intelligent energy frameworks in smart infrastructures. Such research is critical to advancing IoT-driven applications and sustaining continuous progress in this domain. Aspectos destacados • En el sector energético, es necesario un mecanismo operativo cooperativo integrado que tenga en cuenta la entidad de la oferta y la demanda de energía para reducir el desajuste. • La tarea operativa de gestión de la energía busca el desarrollo de un sistema de gestión energética inteligente (SEMS) económico y eficiente. Además, el despliegue de algoritmos de negociación de energía con capacidad de comunicación fiable es esencial para reducir el consumo total de energía y, por lo tanto, minimizar el coste de la electricidad. • Es esencial una iniciativa integral en materia de redes inteligentes, que incluya un marco de gestión energética asociado a un entorno de Internet de las cosas que supervise y visualice el consumo de energía en las instalaciones de los consumidores. • Se deben evaluar las técnicas de optimización para encontrar el enfoque más rentable y eficiente desde el punto de vista computacional para las limitaciones de los consumidores del lado de la demanda. • Se requiere una predicción precisa de la generación de energía o de la disponibilidad de energía para un mecanismo de programación adecuado.

(Universidade Estadual de Ponta Grossa, 2028-09-16) Rodríguez-Parra, Mery; Guerra-Zamora, Paula; Figueroa-Moya, Daniela; Contreras-Contreras, Johana; Poblete-Nuñez, Ximena
Se analiza la Educación Sexual Integral en educación inicial como un enfoque esencial para el bienestar de las infancias y el cuidado. Examina cómo se integran la enseñanza y el ejercicio del cuidado en las prácticas cotidianas de educadoras y técnicas. Metodológicamente, usa un enfoque cualitativo y etnográfico, recogiendo datos a través de entrevistas en profundidad y observación participante en seis centros educativos de tres regiones de Chile. Se realizaron 30 entrevistas y 72 observaciones, analizando los datos mediante ejes temático, combinando codificación deductiva e inductiva. Los resultados revelan que las profesionales integran aspectos de la ESI para abordar el cuidado, incluyendo la perspectiva de derechos, autocuidado, límites e intimidad; el cuidado del cuerpo, afectividad, vínculos y expresión de emociones. Se concluye que la ESI desde la primera infancia es una oportunidad para transformar la organización social del cuidado y promover una sociedad más inclusiva, respetuosa y equitativa. This study examines Comprehensive Sexual Education (CSE) in early childhood education as an essential approach for the well-being of children and care. It explores how teaching and the practice of care are integrated into the daily routines of educators and assistant. Methodologically, it employs a qualitative and ethnographic approach, collecting data through in-depth interviews and participant observation in six educational centres across three regions of Chile. A total of 30 interviews and 72 observations were conducted, with data analysed through thematic axes, combining both deductive and inductive coding.The results reveal that participants incorporate aspects of CSE to address care, including the perspective of rights, self-care, boundaries, and intimacy; the care of the body, affectivity, relationships, and the expression of emotions. It concludes that CSE from early childhood presents an opportunity to transform the social organisation of care and promote a more inclusive, respectful, and equitable society.

Más allá del efecto escuela: una nueva perspectiva sobre el habitus institucional
(Universidad Católica de Temuco, 2025-11-04) Ilabaca, Turri, Tomás; Álvarez Valdés, Carolina
Este trabajo teórico propone un giro conceptual en la noción de habitus institucional en el campo de la sociología de la educación. En los trabajos iniciales, el concepto de habitus institucional fue concebido para interpretar el papel que desempeñan los establecimientos educacionales en la reproducción de trayectorias estudiantiles en el paso hacia la educación superior. Sin embargo, retomando la teoría de Bourdieu, sostenemos que este concepto también permite comprender a los establecimientos como agentes, con habitus, capitales y sentido del juego, y en función de ello responderían a las transformaciones del campo social. Para graficar la propuesta conceptual, se analizan las respuestas de los establecimientos educacionales frente a los cambios en las reglas del juego que ha experimentado el sistema educacional chileno, particularmente a partir de la promulgación de la Ley de Inclusión. Para ello, se realizó una revisión de literatura científica que da cuenta del cambio que ha significado dicha ley para los establecimientos escolares habituados a funcionar bajo una regulación de mercado y lógicas de selección de familias para obtener mejores resultados académicos. Dicha revisión da cuenta de una cierta regularidad en el tipo de respuesta de los establecimientos frente a la ley, donde las diferencias se asocian a la posición en el campo y los capitales que han acumulado en el tiempo. Concluimos que este concepto permite explicar y comprender las reacciones de los establecimientos frente a cambios en las regulaciones del campo educativo. This theoretical work proposes a conceptual shift in the notion of institutional habitus within the field of education sociology. In early studies, the concept of institutional habitus was conceived to interpret the role played by educational institutions in reproducing student trajectories during the transition to higher education. However, drawing on Bourdieu's theory, we argue that this concept also enables understanding schools as agents endowed with habitus, capitals, and a sense of the game, thus responding to transformations within the social field. To illustrate this conceptual proposal, we analyze the responses of educational institutions to the changes in the rules of the game introduced by the Chilean education system, particularly following the enactment of the Inclusion Law. A comprehensive literature review was conducted to document the impact of this law on schools accustomed to operating under market regulations and family selection logics aimed at achieving better academic outcomes. The review reveals a certain regularity in the responses of educational institutions to the law, where differences are associated with their position within the field and the capitals accumulated over time. We conclude that this concept allows for a nuanced explanation and understanding of how institutions react to regulatory changes within the educational field.

Food labelling in India: a scoping review of consumer engagement,comprehension, and purchase behaviour
(Taylor & Francis, 2025-11-11) Pahlani, Maneesha; Talati, Kandarp Narendra; López-Arana, Sandra; Narayanan, Prakash
Amid rising packaged food consumption in India and its associated health risks – including obesityand non-communicable diseases – this scoping review synthesised India-specific evidence onconsumer awareness, comprehension, and behavioural responses to food labels on pre-packagedproducts. Following the Preferred Reporting Items for Systematic Reviews and Meta-Analysesextension for Scoping Reviews checklist and Arksey and O’Malley framework, five databases(PubMed, Scopus, Embase, Web of Science, and CINAHL) and Google Scholar were searched forpeer-reviewed primary studies conducted in India between 2014 and 2024. Studies were included ifthey assessed food label literacy, interpretation, or use in purchase behaviour in Indian settings.Thirty-two studies were included, covering diverse populations and geographic settings.Bibliometric synthesis showed a predominance of cross-sectional knowledge, attitudes, and prac-tices studies, with limited experimental or multidisciplinary research. Findings were organised intothree analytical themes: a) determinants of food label literacy, including socio-demographic andcognitive factors; b) consumer perceptions of label components, their placement on packaging,visual appeal, and cognitive utility; and c) behavioural implications of label engagement and itsperceived influence on purchase intentions. Evidence from this review highlights persistent gapsbetween label awareness, engagement, and purchase intentions. To inform policy and practice –and to advance Sustainable Development Goal 3 (Target 3.4 – reducing premature mortality fromnon-communicable diseases) & Goal 12 (Target 12.8 – promoting awareness and informationaccess) – future research should prioritise experimental and implementation-focused designstailored to India’s demographic, cultural, and market heterogeneity.

Prevalence and determinants of energy drink consumption among chilean adolescents
(MDPI, 2025-11-05) López-Arana, Sandra; Bustos-Arriagada, Edson
Background: Energy drink (ED) consumption has increased significantly among adolescents worldwide, constituting a high-risk behavior with important public health implications. These beverages are associated with cardiovascular disturbances, sleep disorders, anxiety symptoms, and risky behaviors, especially when combined with alcohol. In Chile, monthly per capita ED consumption among individuals aged 14 to 30 increased ninefold between 2010 and 2020. Objectives: To examine the prevalence of ED consumption and its associated determinants among Chilean adolescents enrolled in grade eight through grade twelve. Methods: Data were drawn from the national representative survey 2023 entitled Fifteenth National Study on the School Population of Chile (ENPE). The final sample included 45,042 adolescents. Besides descriptive analyses, both bivariate and multivariate logistic regression models were used to examine associations between sociodemographic characteristics, parental presence, monitoring, and ED consumption outcomes. Results: Lifetime prevalence of ED consumption was 71.0%, with higher rates in females (72.8%) than males (69.4%). Past-month consumption was reported by 46.2%, with a higher prevalence in males (48.3%) than females (43.9%). Lifetime consumption of ED mixed with alcohol (AmED) was 23.2%, being more frequent among females (26.4%) than males (19.9%). Age, grade level, and indigenous identity were consistently associated with higher odds of consumption. Parental monitoring and involvement indicators were inversely associated with both ED and AmED consumption. Conclusions: This study reveals a high prevalence of ED consumption among Chilean adolescents, with notable gender differences. Family protective factors, particularly parental monitoring and cohesion, emerge as key determinants of this risky behavior and warrant prioritization in public health prevention efforts.
