A causal and correlational investigation was carried out of a non-experimental and transversal nature, in which 1,000 tourists who visited the city of Arequipa-Peru participated. These were intentionally selected to represent a specific sample. Two expert-validated surveys were used for data collection. The results indicated a moderate level of environmental education, with foreign professional women showing profound environmental knowledge. On the contrary, young national professionals demonstrated a profound commitment to the environment. These results underscore the significant link between environmental education and sustainable tourism. Nevertheless, a definitive conclusion was not reached about the study, as there could be other contributing factors.</p>2024-02-27T16:16:55+00:00Copyright (c) 2024 James Josmell Ojeda Portugal, Cecilia Alejandra Alarcon Vilca, Jeniffer Stephanie Diaz Santivanez, Diana Soledad Maquera Yucra, Raul Mauro Gonzales-Velizhttps://minerva.autanabooks.com/index.php/Minerva/article/view/148Mathematical model in the optimization of the cost of heavy agricultural cargo transportation2024-02-28T19:39:12+00:00Juan Alberto Avalos Reyesjavalos@espoch.edu.ecPatricia Mercedes Cepeda Silvapatricia.cepeda@espoch.edu.ecPaul Caceresalejandro.caceres@espoch.edu.ec<p><span class="OYPEnA text-decoration-none text-strikethrough-none">This work aimed to design a mathematical model to optimize the cost of heavy agricultural load transport using linear programming. The model was based on studying fixed and variable costs, including distance, cargo volume, arrival and departure times, lubricants, fuels, and other variables that influence transport pricing. The work had a quantitative approach, descriptive type, and its design of the non-experimental character with a cross-section. The methods were used, inductive, deductive, and systemic. For the collection of information, the survey was used as a technique and the questionnaire as an instrument, evidencing that most carriers do not know the calculation of the actual cost of transport, thus visualizing the need for a mathematical model in cost optimization, an achievement validated in the WINQSB program (Network Modeling Module).</span></p>2024-02-27T16:46:34+00:00Copyright (c) 2024 Juan Alberto Avalos Reyes, Patricia Mercedes Cepeda Silva, Paul Cacereshttps://minerva.autanabooks.com/index.php/Minerva/article/view/149Design of an educational strategy based on digital resources for the teaching of social sciences2024-02-28T19:39:49+00:00Cesar Camilo Zambrano Tomalaczambrano6443@utm.edu.ecJisson Oswaldo Vega Intriagojisson.vega@utm.edu.ecMarcos Fernando Pazmino Campuzanomarcos.pazmino@utm.edu.ec<p>This research proposes a pedagogical strategy incorporating digital tools for teaching Social Sciences. A quantitative approach is employed data collection targeting educational authorities, teachers, and students to assess the commitment and feasibility of implementing a new educational proposal. The results reflect the commitment and interest of participants towards creating this pedagogical strategy. Various digital tools are suggested, including Telegram for communication, ChatGPT and Virtual Encyclopedias for content generation, Kahoot and Google Form for assessment, and Timeline JS and Powtoon for dynamic presentations. Finally, the proposal was validated through a comparative study between a control group and an experimental one. The findings indicate that the new pedagogical strategy offers a higher innovation, relevance, and improvement in students' learning process.</p>2024-02-27T00:00:00+00:00Copyright (c) 2024 Cesar Camilo Zambrano Tomala, Jisson Oswaldo Vega Intriago, Marcos Fernando Pazmino Campuzanohttps://minerva.autanabooks.com/index.php/Minerva/article/view/150Use of calcium zeolite as an absorption agent for arsenic and lead in mine tailings2024-02-28T19:39:36+00:00Patricio Feijoopfeijoo@uazuay.edu.ecEduardo Lunaeluna@uazuay.edu.ec<p><span class="OYPEnA text-decoration-none text-strikethrough-none">Metallurgical processes in beneficiation plants, generate large quantities of waste called mining tailings, which are harmful to the environment and health due to the heavy metals present. These tailings are sometimes deposited in water effluents, close to mining production areas. Therefore, the purpose of the present investigation was to propose partial remediation of the exposed problem, with the use of zeolite, depositing this mineral on and under the mining tailings, carrying out 10 tests, with variation in the amount of zeolite, from 100 to 500 grams. The trials were subject to an action time of 30 days. The results obtained in the experimentation show that the test with 500 grams, placed at the bottom of the tailings, was the most efficient for the absorption of heavy metals, specifically with results of 43% in lead and 51% in arsenic, which benefits to the environment.</span></p>2024-02-27T00:00:00+00:00Copyright (c) 2024 Patricio Feijoo, Eduardo Lunahttps://minerva.autanabooks.com/index.php/Minerva/article/view/151Project Based Learning to promote the teaching of chemistry2024-03-08T09:50:41+00:00Karla Sofia Echeverria Gilerkecheverria5903@utm.edu.ecJean Carlos Perez Parrajean.perez@utm.edu.ec<p><span class="OYPEnA text-decoration-none text-strikethrough-none">El Aprendizaje Basado en Proyectos (ABP) se posiciona como una estrategia educativa valiosa que promueve el desarrollo de habilidades para la resolución de problemas prácticos. En este estudio se investigó la efectividad del ABP en comparación con el método de enseñanza tradicional en el contexto de la enseñanza de la química en la educación secundaria, específicamente en el abordaje del tema ácido-base. Para ello se empleó una muestra de 42 estudiantes de bachillerato. Los participantes se dividieron equitativamente en dos grupos de 21 estudiantes: Uno sometido al enfoque ABP (grupo experimental) y otro al enfoque tradicional (grupo de control). Se aplicaron dos test, uno previo y otro posterior a la intervención, a ambos grupos. La investigación se apoyó en el análisis de los resultados obtenidos a través de la prueba t-student para comparación de medias. Los resultados arrojaron que el ABP tiene un impacto significativo en el proceso de aprendizaje.</span></p>2024-03-07T16:08:56+00:00Copyright (c) 2024 Karla Sofia Echeverria Giler, Jean Carlos Perez Parrahttps://minerva.autanabooks.com/index.php/Minerva/article/view/152The Role of object-oriented Programming in sustainable and Scalable Software Development2024-03-08T09:50:29+00:00Jose Belisario Vera Verabelisariovera@espam.edu.ecJose Rafael Vera Verajose_verav@espam.edu.ec<p><span class="OYPEnA text-decoration-none text-strikethrough-none">This study empirically evaluates how various practices and principles of object-oriented programming (OOP) impact the sustainability and scalability of software projects. A detailed analysis of real-world projects is carried out, considering aspects such as encapsulation, code reuse, modularity, and the application of inheritance and polymorphism. The goal was to identify patterns and best practices contributing to efficient and adaptable software development.

The main results show that it is possible to obtain a pure and refined glycerol, in addition, it was observed that the parameters were within the regulations presented by several authors. It was also observed that the glycerol with better properties was obtained at 60 minutes at a temperature of 60ºC. In this way, it is possible to affirm that it is viable to use discarded oils as an alternative for their application in the elaboration of products that benefit the chemical, cosmetic, and pharmaceutical industries, as is the case of hydrogel, thus avoiding their incorporation into the environment.</span></p>2024-03-08T17:14:50+00:00Copyright (c) 2024 Steeven Jose Analuisa Mero, Luis Alberto Moreno Ponce, Segundo Alcides Garcia Muentes, Ramon Eudoro Cevallos Cedeno, Ariana Milena Garcia Bowen
