Informe de Grado Cueros Vélez S.A.S

(Universidad Santo Tomás, 2025) Pedroza Naranjo, Erika Viviana; Sánchez Restrepo, Santiago; Universidad Santo Tomás; https://scienti.minciencias.gov.co/cvlac/visualizador/generarCurriculoCv.do?cod_rh=0002083888

The following work will focus on publicizing business practices at Cueros Vélez S.A.S., a leading company in the fashion and leather sector in Colombia. This work seeks to integrate the knowledge acquired during academic training with the dynamics and real challenges of an organization recognized for its excellence in design, manufacture and marketing of leather products. As a practitioner, I hope to contribute to the development of innovative solutions and effective strategies that have a positive impact on the company’s internal processes. In addition, this job represents an opportunity to gain experience in a competitive business environment, strengthen my professional skills and add value to a company with a solid track record in the national and international market.

Road infrastructure works are an important element for the economic and social development of a country, they allow the connection from one point to another, as well as the transport of different goods and services, as well as people. Their construction is crucial in favor of the economy of a country, however, different environmental problems have been demonstrated that negatively impact the environment where they are built, the constant evidence of effects on ecosystems, the contamination of water sources and the alteration of the landscape, managed to generate the need to create new and adequate mechanisms for the conservation of natural resources and the care of species to compensate the damage generated. Green road infrastructure works will minimize the environmental impacts that are generated from road constructions, forging tools with which future strategies can be made against the impacts generated in such constructions.

Quemadura de córnea con látex de banano en ojo derecho en 2024: Reporte de caso

(Universidad Santo Tomás, 2025-03-27) Cardozo Calderón, Yessica Alexandra; Pérez Sánchez, Rafael Eduardo; Narváez, Olivia Margarita

Objective: Prepare a case report of a corneal burn with banana latex in 2024, in Urabá, Antioquia. Results: The case of a 54-year-old male patient is presented, who was referred for consultation due to a chemical corneal burn caused by contact with banana latex in the right eye. Initial symptoms included severe pain, photophobia, and blurred vision. During the ophthalmological examination, lesions were diagnosed that compromised corneal transparency and significantly affected vision, with partial visual recovery after treatment. Conclusions: This case highlights the importance of an early and accurate diagnosis in chemical corneal burns, since timely intervention can improve visual prognosis and prevent long-term complications

Estrategia Lúdica para Fortalecer el Aprendizaje de las Matemáticas y el Pensamiento Crítico en Estudiantes de Tercer Grado: Hacia la Optimización de Prácticas Pedagógicas en el Aula.

(Universidad Santo Tomás, 2025) Quintero Portillo, Betsi; González Navarro, Wilson; Pedraza Hernández, Yily Darley; Universidad Santo Tomás; https://scienti.minciencias.gov.co/cvlac/visualizador/generarCurriculoCv.do?cod_rh=0001857387; https://orcid.org/0009-0005-0019-1390

This study focuses on the poor performance in mathematics of third grade students, specifically on the understanding of the numerical structure and the impact of this on their academic performance. Using a Participatory Action Research (PAR) approach and mixed methods design, the research implements a playful strategy based on educational games such as the mathematical park, numerical bingos and mathematical challenge wheels, to improve the understanding of mathematical concepts and develop critical thinking. The study was carried out with 35 students from the Juan Pablo Primero Educational Institution in Cúcuta, aged between 8 and 10 years, from various socioeconomic backgrounds, including vulnerable populations. Three teachers and 30 parents also participated. Data collection included qualitative and quantitative techniques: surveys, diagnostic tests, semi-structured interviews and participatory observation. The methodology was structured in four phases: 1) Diagnosis, which included initial tests for third grade students, interviews with teachers and systematic observation; 2) Planning of playful strategies, incorporating digital interactive games, adapted board games, group challenges and playful narratives; 3) Practical implementation in the classroom with direct observation and practical workshops; and 4) Impact evaluation through diagnostic tests and final surveys. The following results were evidenced, showing a significant improvement in academic performance, with an increase in the average grade from 26.49 to 34.91 points and a reduction in the variability of the results (standard deviation from 8.66 to 6.31). Attitudes towards mathematics improved notably: liking for the subject increased from 51.43% to 68.6%, while anxiety when solving problems was reduced from 66% to 26%, significantly improving the problems evidenced in the teaching of mathematics. The research concludes that the implementation of playful strategies has a positive impact on mathematical understanding and the development of critical thinking. It is recommended to incorporate play activities into regular teaching practice, promote collaboration between teachers, families and the educational community, and conduct future research on the long-term impact of these strategies, as well as explore innovative approaches that integrate mathematics with other areas of knowledge. Keywords: Mathematics learning, Playful strategy, Critical thinking, Pedagogical practice in primary school.
