(Sociedad Chilena de Nutrición, Bromatología y Toxicología, 2025-12-31) Bustos-Arriagada, Edson; López-Arana, Sandra; Duarte-Silva, Lissette; Castillo-Valenzuela, Oscar
Introducción: El Observatorio Nutricional Nestlé –Universidad Finis Terrae surge como respuesta a la limitada información disponible sobre la alimentación, nutrición y estilos de vida en niños, niñas y adolescentes (NNA) chilenos. Objetivo: Describir las características del observatorio nutricional Nestlé-Finis Terrae y los principales hallazgos del período 2022-2024. Sujetos y métodos: A través de encuestas telefónicas estructuradas a personas adultas que se identifican como padres o madres de niños, niñas y adolescentes entre 2 y 15 años, residentes en Chile, se ha monitoreado desde el año 2022 el comportamiento alimentario y estilos de vida de padres, cuidadores y sus hijos. Resultados: Entre los principales hallazgos destaca una elevada percepción de alimentación equilibrada a nivel familiar, con valores relativamente estables entre 2022 y 2024: 57% (intervalo de confianza del 95%, IC 95%: 52,9–61,0) en 2022, 51% (IC 95%: 46,9–55,1) en 2023 y 56% (IC 95%: 51,9–60,0) en 2024. Se observó un aumento sostenido de la improvisación alimentaria, desde 51% en 2022 a 60% en 2024. La preocupación por los precios de los alimentos también creció, de 17% en 2023 a 25% en 2024. En 2023 se registró el mayor nivel de percepción de alergias e intolerancias no diagnosticadas (33%, IC 95%: 29,2–36,9). Además, se identificó una subestimación del estado nutricional real de los hijos y bajo cumplimiento de las recomendaciones sobre actividad física y uso de pantallas. Conclusión: El observatorio se caracteriza por una metodología estandarizada y la continuidad anual en la recolección de datos, lo que permite disponer de información consistente sobre percepciones en salud y nutrición infantil. Aunque el uso de datos autorreportados representa una limitación, los resultados obtenidos constituyen un insumo relevante para el diseño de políticas públicas y estrategias educativas orientadas a promover hábitos de vida más saludables en la infancia y adolescencia chilena. Introduction: The Nestlé–Universidad Finis Terrae Nutritional Observatory was created in response to the limited information available on the diet, nutrition, and lifestyles of Chilean children and adolescents. Objective: To describe the characteristics of the Nestlé–Finis Terrae Nutritional Observatory and the main findings from the 2022–2024 period. Subjects and methods: Since 2022, structured telephone surveys have been conducted with adults who identify as parents of children and adolescents aged 2 to 15 years, residing in Chile. These surveys monitor the eating behaviors and lifestyle habits of parents, caregivers, and their children. Results: One of the main findings was a high perception of balanced family nutrition, with relatively stable values across the years: 57% (95% confidence interval, CI 95%: 52.9–61.0) in 2022, 51% (CI 95%: 46.9–55.1) in 2023, and 56% (CI 95%: 51.9–60.0) in 2024. A steady increase in improvised eating was observed, rising from 51% in 2022 to 60% in 2024. Concern about food prices also grew, from 17% in 2023 to 25% in 2024. In 2023, the highest level of rerceived undiagnosed allergies and intolerances was recorded (33%, CI 95%: 29.2–36.9). Additionally, there was evidence of underestimation of children’s actual nutritional status and low adherence to recommendations regarding physical activity and screen time. Conclusion: The observatory is distinguished by its standardized methodology and annual data collection, providing consistent information on perceptions related to child health and nutrition. Although the use of self-reported data is a limitation, the findings offer valuable input for the development of public policies and educational strategies aimed at promoting healthier lifestyles among Chilean children and adolescents.

A review of IoT enabled intelligent smart energy management for photovoltaic power forecasting and generation
(Elsevier, 2026-01-05) 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.

Insectario: estructuras artrópodas para un diseño morfogenético interespecie
(Universidad Politecnica de Cataluña, 0025-10-28) Salvatierra Meza, Belén
Este trabajo describe una experiencia pedagógica en segundo año, donde mediante enfoques de Research by Design (RbD), se investigó la morfogénesis de insectos y su potencial para orientar el diseño de estructuras resilientes frente a crisis ecológicas. La observación con lupas y microscopios permitió analizar exoesqueletos y reconocer patrones de segmentación, articulación y envolventes, traducidos en tensores, pieles y módulos. Estos principios derivaron en sistemas modulares replicables, asumiendo la estructura como generadora de espacio. El proceso articuló dibujo, diagramas, modelos y prototipos, integrando diversas escalas y conocimientos. Los resultados evidenciaron un alto desarrollo conceptual, habilitando cruces entre biología, técnica y diseño, delineando escenarios especulativos para nuevas formas de cohabitación. This work describes a second-year pedagogical experience in which, through Research by Design (RbD) approaches, the morphogenesis of insects was investigated for its potential to guide the design of resilient structures in the fase of ecological crises. Observation with magnifying glasses and microscopes enabled the análisis of exoskeletons and the identification of pattern of segmentation, articulation, and envelopes, translated into tensión elements, skins, and modules. These principles gave rise to replicable modular systems, understanding structure as a generator of space. The process wove together drawing, diagrams, physical models, and prototypes, integrating multiple scales and bodies of knowledge. The results showed a high leve of conceptual development, enabling intersections among biology, technique, and design, and outlining speculative scenarios for new forms of cohabitation.

Madres del mar: maternar y cuidar en las caletas pesqueras
(Revista Punto Género, 2025-12) Undurraga, Rosario; Basualto, Camilo
Este estudio cualitativo examina las experiencias de maternidad y cuidado de mujeres trabajadoras en caletas pesqueras artesanales del litoral central chileno. A partir de 11 entrevistas, se analizan las estrategias que estas mujeres despliegan para conciliar mandatos tradicionales de género con el trabajo remunerado en espacios laborales masculinizados. Los hallazgos muestran regímenes híbridos de cuidado —familiarista, comunitario-solidario y autonomía precarizada— que surgen ante la precariedad y la crisis sistémica del cuidado, junto con tensiones entre la transmisión de saberes pesqueros y el deseo de movilidad social para sus hijos/as. La doble jornada, la territorialidad costera y la violencia de género configuran trayectorias vitales y maternidades situadas que combinan reproducción y subversión de normas de género y desigualdades sociales. El artículo concluye con un llamado a políticas de corresponsabilidad que reconozcan el trabajo productivo y reproductivo invisibilizado de estas trabajadoras del mar, desnaturalizando el autosacrificio como la única vía para la sostenibilidad vital. This qualitative study examines the experiences of motherhood and caregiving among women working in artisanal fishing coves along the central coast of Chile. Based on 11 interviews, it analyzes the strategies these women deploy to reconcile traditional gender norms with paid work in masculinized workspaces. The findings reveal hybrid care regimes —familiarist, communitybased/solidary, and precarious autonomy— that emerge in response to precarious conditions and the systemic crisis of care, along with tensions between the transmission of fishing knowledge and the aspiration for social mobility for their children. The double burden, coastal territoriality, and gender-based violence shape life trajectories and situated motherhoods that simultaneously reproduce and challenge gender norms and social inequalities. The article concludes with a call for co-responsibility policies that acknowledge the undervalued productive and reproductive labor of these women working in small-scale fisheries, questioning the normalization of self-sacrifice as the only path to sustaining life.

Prevalence and determinants of energy drink consumption among chilean adolescents
(MPDI, 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.
