Estudio de digestibilidad de nutrientes en pollos de carne alimentados con diferentes fuentes de fibra
(Ecuador : Pujilí : Universidad Técnica de Cotopaxi (UTC), 2024) Real Nuñez, Henry Leonardo; Herrera Herrera, Rocio del Carmen
Nutrient digestibility allows to optimize and improve feed conversion and productive performance in birds, so there is a need to evaluate food alternatives that cover their nutritional requirements. The general objective of the following research was to determine the nutrient digestibility in broiler chickens fed with different sources of fiber. For the development of the research, 64 chickens of the Cobb 500 line of 42 days of age were used, with an average weight of 7075 g, they were randomly assigned to four treatments including different sources of fiber T1: control, T2: 18% wheat bran, T3: 18% rice husk and T4: 18% palm kernel. The diets were formulated considering the nutritional requirements of the Cobb 500 chicken line. A completely randomized design was applied. The variables studied were dry matter digestibility, organic matter, crude fiber, crude fat, crude protein. The data were analyzed in the statistical package Infostat by means of a variance analysis, in which the fiber sources were taken as the main variation factors and the Tukey test was used to compare means. The results presented statistical differences, p < 0,05 for dry matter, organic matter and crude fiber, showing a higher percentage of digestibility with the inclusion of 5% of wheat bran with 80.3; 67.00; 15.06% respectively; while for crude protein p = 0.181 and crude fat p = 0.281, there was no difference between treatments. It is concluded that the inclusion of fiber sources in the diet of broilers shows acceptable nutrient digestibility percentages.

Teachers’ perceptions of virtual reality in the development of vocabulary
(Ecuador : Pujilí : Universidad Técnica de Cotopaxi (UTC), 2023) Pacheco Díaz, Francis Marcelo; Cando, Fabiola Soledad
Virtual reality is a technological tool that provides immersive learning experiences for a better understanding, promotes collaborative work, and contains authentic material to develop communicative competencies. Users can witness new things that the real environment cannot provide for learning. This qualitative research aimed to describe the teachers' perception of virtual reality in English language learning after participating in a training course of 5 sessions. It was phenomenological research because it analyzed 5 English teachers’ experiences after being immersed in the virtual world to test VR apps to develop language. Participants tried 5 apps where students can enhance their language. Data was collected by using participants' journals. The teachers’ reflections were analyzed through thematic analysis. The study shows that teachers believe that virtual reality can positively assist students in English language learning with an immersive language environment, authentic material, hands-on activities, and audio-visual aids. Teachers showed positive attitudes toward virtual reality to improve English language learning and teaching with this technological tool. Teachers suggest virtual reality promotes higher opportunities to enhance language learning and teaching. In conclusion, Virtual reality is an effective learning tool that teachers can apply in their classes to make them more engaging and meaningful for students.

Evaluación del Estado Emocional de los empleados de la empresa FenixCorp-ADS mediante el uso de Machine Learning.
(Ecuador: Latacunga: Universidad Técnica de Cotopaxi (UT, 2024-12) Tello Oña, Yomara Elizabeth; Quisaguano Collaguazo, Luis René
Artificial Intelligence (AI) is currently booming, not only in industrial processes, but also in fields related to activities that contribute to the development of organizations and human knowledge. Machine Learning is contained within the computational context of AI, divided into three main approaches: Supervised Machine Learning (AAS), Unsupervised Machine Learning and Reinforcement Learning, which are techniques and algorithms capable of “learning and reasoning” by simulating the human brain, and allows classifying and predicting the behavior of the data supplied to the chosen model, through the use of the SciKit-Learn library and other Python tools, a programming language widely used in data analysis and sentiment analysis, another tool for extracting information based on subjective opinions. Emotional State (ES) is a conscious and unconscious reaction in response to a specific stimulus at a specific time or situation that individuals have. In order to establish a possible relationship with the work performance of employees and the talent drain of the company FenixCorp-ADS, a questionnaire was developed via Web and the classification and prediction algorithms of supervised and unsupervised machine learning were chosen, which allowed to develop a comparative analysis to determine the most efficient model of sentiment analysis performed, contributing in its application in a more continuous way by business organizations in order to use it to automate these processes.

La variedad lingüística ecuatoriana a través del podcast educativo
(Ecuador: Latacunga: Universidad Técnica de Cotopaxi (UTC), 2024-08) Alajo Anchatuña, Andrea Salomé; Guagchinga Chicaiza, Nelson Wilfrido
Ecuador is a country with great linguistic diversity, with 14 official indigenous languages in addition to Spanish. This study focuses on the use of educational podcasts to teach fifth grade basic education students about the linguistic variety in Ecuador. The methodology of this research is qualitative, which included literature review, document analysis and interviews with experts. The study found that educational podcasts can be an effective tool for teaching students about the linguistic variety in Ecuador. The students who participated in the study showed greater knowledge of the different varieties of Spanish spoken in the country, as well as a greater interest in the culture and history of Ecuador. The research concludes that the use of educational podcasts can be an effective strategy to promote learning of the linguistic variety in Ecuador.

Desarrollo de indicadores de sostenibilidad ambiental como estrategia de protección y recuperación del páramo San Isidro, Cantón Pujilí, Provincia de Cotopaxi
(Ecuador: Cotopaxi: Latacunga: Universidad Técnica de Cotopaxi (UTC), 2024-08) Mena Pástor, Johny Adrián; Cajas Cayo, Isaac Eduardo
The project focuses on the development of environmental sustainability indicators as a protection and recovery strategy for the San Isidro páramo in Pujilí Canton, Cotopaxi Province. The main objective of this project was to develop environmental sustainability indicators as a protection and recovery strategy for the San Isidro páramo, Pujilí Canton. Specific objectives included the diagnosis of the current state of the páramo, the development of a local model using the PER (Pressure, State, Response) methodology, and the generation of environmental sustainability indicators. The methodology employed combined qualitative techniques, including the use of geospatial technologies such as the Global Positioning System and Geographic Information Systems for the collection and spatial analysis of environmental and socioeconomic data. A participatory approach was applied, integrating the perspective of the local community in the development of indicators. The results revealed a significant interdependence between the ecological health of the páramo and the socioeconomic well-being of the surrounding communities. The twenty-four proposed sustainability indicators reflect this relationship, covering aspects such as water quality, vegetation cover, biodiversity and changes in land use. The project highlights the usefulness of environmental sustainability indicators in effectively monitoring the ecological health of the San Isidro páramo and in promoting informed environmental management. The adoption of these indicators by the Prefecture of Cotopaxi and the GAD of Pujilí is recommended, in order to integrate them into their conservation policies and practices, ensuring a holistic and effective approach to environmental sustainability. This initiative represents a significant step towards the long-term conservation of one of the most valuable and vulnerable ecosystems, providing a replicable model for other protected areas in Ecuador and in the Andean region. The implementation of the indicators will allow local authorities and stakeholders to have a clearer and more quantifiable understanding of the impacts of human activities on the páramo ecosystem, favoring evidence-based decision-making for its management and restoration.
