Get PDFDOI: https://doi.org/10.46296/ig.v8i15.0262
This narrative review examines the fundamental role of mathematical visualization in enhancing students' conceptual understanding. Through a systematic analysis of 62 recent academic publications, it explores how visual representations transform abstract ideas into concrete experiences, particularly in algebra and geometry. The results reveal that visualization not only facilitates the internalization of complex concepts but also strengthens connections between different mathematical areas, promoting stronger relational understanding. Various educational resources are identified, from physical manipulatives to specialized software such as GeoGebra, allowing students to dynamically explore mathematical relationships. However, effective implementation faces challenges such as insufficient teacher training and the need to adapt strategies to diverse learning styles. Pedagogical implications point toward a multimodal approach that systematically integrates visualization into mathematics curricula and promotes active learning. This review contributes to the educational field by providing a critical synthesis of how visualization can positively transform the mathematical learning experience, building bridges between disciplinary abstraction and students' concrete experiences.

Análisis de modos y efectos de fallas en una sala de máquinas de un hospital
Get PDFMaintenance in Hospitals is very important due to the high levels of risk for patients and the complexity and diversity of the equipment they have to provide their services. The objective of this work was to apply the analysis of failure modes and effects in the engine room of a Hospital in order to increase the availability of the equipment. The methodological strategy followed included the criticality analysis and the application of the FMEA, which is one of the main tools of the RCM. The fundamental results of the criticality analysis showed that the two highly critical pieces of equipment were the boilers. The failure mode and effect analysis carried out in the boilers showed that the most significant failures occurred in the burner due to the deterioration of the nozzle and in the electric motor of the fan due to the wear of the bearings due to unbalance and misalignment. These results allowed us to define the maintenance actions necessary to prevent this type of failure.
