El presente estudio tuvo por objetivo evaluar los factores del liderazgo institucional que influyen en la promoción de prácticas inclusivas docentes en una institución educativa, Alto Amazonas-2024, pretendiendo hacer una contribución al ODS-4; siguiendo el método hipotético-deductivo, investigación básica, no experimental, y correlacional-causal, aplicándose dos cuestionarios a 75 docentes. Descriptivamente, para el liderazgo institucional, se determinaron tres niveles: desfavorable (13%), moderado (27%) y favorable (60%); para las prácticas inclusivas fueron: inadecuada (13%), regular (39%) y alto (48%). En los inferenciales, la prueba regresión ordinal arrojó una asociación significativa (Chi2=62.290, Sig.=0.000) y un coeficiente R2 Nagelkerke=0.655, además de “coeficientes Wald”>zona crítica (Zc95%=1.64) y Sig.<0.05 entre la variable practicas inclusivas docentes y...

The proposed Sustainable Energy Model is based on rice husk and the development of briquettes made from agricultural waste, which will increase efficiency in the domestic sector, and potentially replace conventional polluting fuels such as firewood. Large volumes of rice husks from millers are found scattered in rural agricultural areas of the San Martin region of Peru, where people are exposed daily to the emissions of polluting gases produced by burning these wastes, causing respiratory and lung diseases. Despite present circumstances, this waste has a great energetic potential that is not yet used by society, representing an opportunity to encourage socioenvironmental development and generate added value to the husk. Based on a compaction and drying process, briquettes were obtained with 4,040 kcal / kg of heat power and 80.39% combustion efficiency, allowing the little use of biofuel...

Electrification of low-income rural areas that have a limited connection or no access to electrical grids is one of the most demanding challenges in developing countries such as Peru. The international commitment to stop global warming and the reduction in the cost of renewable sources of energy have reduced the prices of fossil fuels in some cases. This has opened the way to the current research which proposes a hybrid energy system (HES) based on the use of renewable sources of energy. Therefore, a renewable electricity system (HRES) was set up at the village of Monte-Catache in the Cajamarca region, which is one of the poorest areas of Peru. Surveys and field studies were used to evaluate the socioeconomic characteristics, availability of renewable energy resources, and energy demand of this region. Potential energy sources were evaluated, and isolated photovoltaic systems with a batt...

Since its creation in 2011, the DDMRP planning method has been catalogued as an important tool to deal with the high variability of the environment, especially in demand, since it allows modifying inventory levels without neglecting the level of service and quality of the products. However, the volume of research available on this method is small, even more, so those considering the application in complex industries. The objective of this research was to analyze the available literature about the application of the model in complex industries, considering its application trends, buffer positioning and improvement target factors. In addition, it allowed identifying areas that other researchers should study in the future. This systematic review scrutinized different applications of the method in complex industries worldwide by analysing literature in different languages. This research iden...

This research aims to enhance the classification of the rock mass in underground mining, a common problem due to geological alterations that do not fit existing methods. Artificial neural networks are proposed as a solution, which use input/output data to learn and solve problems. The process involves gathering data on rock properties and training the neural networks to identify and classify various types of rock. Once trained, the neural networks can classify the rock mass in real-time during mine design and progression, adapting to different rock types with a low margin of error of 0.279% in determining the RMR index. This research overcomes the limitations of current classification methods, providing a more accurate and reliable solution for the classification of the rock mass in underground mining. In summary, artificial neural networks are utilized to improve the classification of r...

The article's objective was the implementation of the lean manufacturing methodology in the production process of an air conditioning metal processing plant. For this, the methodology of 2 phases was used. The company and its current operation, structure, products, and work plan are presented in the first phase, demonstrating its main deficiencies. In phase 2, an improvement plan was made with lean manufacturing tools applied to the deficit of phase 1. As a result of the implementation of these tools, 64%, 80%, 71% and 50% of space in the measuring, cutting, bending, and welding stations, respectively, and an improvement in production times were obtained. Based on the study results, it is concluded that the application of lean manufacturing benefited the company by drastically improving its production process and work environment.

En la actualidad el entorno globalizado y constantemente cambiante de los negocios ha llevado a las organizaciones a desarrollar sus servicios rápidamente para poder ser más competitivos en el mercado. Sin embargo, la necesidad de ir probando las diferentes funcionalidades de un servicio en marcha e ir testeando, para acabar ofreciendo una solución final, es considerada una tarea complicada y de muy alto costo. La literatura estudiada muestra que se han generado modelos de diseño de servicios con enfoque ágil, pero orientados a corporaciones ya establecidas o con diseños muy robustos que presuponen altos costos; a la fecha de desarrollo de esta investigación no se han encontrado modelos con una orientación hacia nuevos emprendimientos o startups de servicio. En el presente artículo se propone un modelo ágil para el diseño de servicios, el cual destaca principalmente la agilida...

The contamination of seafood by common bacteria and the ecological limitations of antibacterials has prompted the investigation of the phytochemical profile and antimicrobial activity of aqueous garlic extract (Allium sativum L.) against four significant food-associated pathogens: Salmonella typhi, Micrococcus luteus, Staphylococcus aureus, and Escherichia coli. Absorbance curves were constructed, inhibition halos were measured, and minimum lethal concentrations were determined. This study aims to harness the properties of garlic and its derivatives, making them ideal for use in pharmaceutical and industrial products. The results showed greater inhibitory activity against Gram-positive bacteria compared to Gram-negative bacteria. Specifically, a concentration of 0.125 g/ml of the extract produced inhibition halos with diameters of 0.75 mm for S. typhi, 0.8 mm for M. luteus, 11 mm for S. ...

To control the overbreaking of an underground mining development gallery, the controlled blasting technique was proposed and as a result it was possible to reduce costs and improve the physical stability of the periphery of the opening, achieving greater safety for personnel and equipment. With the support of the geomechanical studies, the rock quality of the advancing front was determined, serving for the design of the drilling mesh and the choice and distribution of the explosives in the respective drills. This study demonstrates that it is possible to make progress in efficient mining preparation and development work, achieving minimal damage to the roof and walls of the mining work. Performing the simulation with the software determines a difference between conventional blasting with the design of the pre-cut technique, optimizing the parameters of the perforation mesh, selection of ...
