Solid-state lighting technology, such as LED devices, is critical to improving energy efficiency in street lighting systems. In Ecuador, government policies have established the obligation to exclusively use LED systems starting in 2023, except in special projects. Ecuador, known for its vast biodiversity, protects its national parks, which are rich in flora, fauna and natural resources, through international institutions and agreements such as UNESCO, CBD and CITES. Although reducing electrical consumption usually measures energy efficiency, this article goes further. It considers aspects such as the correlated color temperature in the lighting design of protected areas, light pollution and the decrease in energy quality due to harmonic distortion. Measurements of the electromagnetic spectrum of the light sources were made in an area in the Galápagos National Park of Ecuador, revealing highly correlated color temperatures that can affect ecosystem cycles. In addition, the investigation detected levels of light pollution increasing the night sky brightness and a notable presence of harmonic distortion in the electrical grid. Using simulations to predict the behavior of these variables offers an efficient option to help preserve protected environments and the quality of energy supply while promoting energy savings.

Las carreras en línea son una alternativa educativa con beneficios de contexto, movilidad, economía, tiempo, entre otros factores enfocados en la ciudadanía en general y en los grupos de atención prioritaria en específico. La educación virtual, sin embargo, requiere de un planteamiento organizado, en aspectos pedagógicos para que su implementación sea exitosa. La enseñanza eficiente en educación en línea requiere el cumplimiento de objetivos previstos en los distintos programas de educación universitaria. En este artículo se analizan algunas consideraciones pedagógicas asociadas al contexto, que deben ser tomadas en cuenta por parte de las instituciones de educación superior que propongan carreras en línea, con el fin de mejorar la eficiencia en sus procesos de enseñanza. Estas consideraciones pedagógicas incluyen la interactividad entre participantes, los recursos tecnológicos y financieros, la brecha digital intergeneracional, la autorregulación del tiempo, el conocimiento del propio estilo de aprendizaje y el acompañamiento por parte del profesorado. A través de un análisis descriptivo se observará la relación que tienen estos factores con el éxito académico de los estudiantes y las decisiones que el profesorado puede tomar en función de los resultados presentados.

Water Cherenkov Detectors (WCDs), which are part of the LAGO experimental array, are being built in the cities of Riobamba, Quito and Cumbaya in Ecuador. In order to increase the sensitivity and efficiency of these devices, it is necessary to ensure that the water used as radiator media absorbs as low as possible the UV light due to the incident particles and produced by Cherenkov effect. To do this, we built and used a device that allows us to measure the attenuation length directly. Water samples purified by different techniques are analyzed. Some characteristics like absorbance, refractive index, conductivity and cost are studied. We attempt to simulate the Cherenkov effect in FLUKA, we report our findings and perform a comparison with results from previous reports of LAGO sites elsewhere, and with other experiments that use WCD technology
