The objective of this research was to diagnose ergonomic risks from both physical and cognitive dimensions in workers at the Logistics Center of the University of Matanzas, Cuba. A quantitative, descriptive, non-experimental, and cross-sectional methodology was applied, involving workers in the roles of warehouse assistant, supply and material technician (TATM), and commercial management technician (TEC). For the physical dimension, the Step Test and the tabular method were used to calculate physical work capacity (PWC) and energy expenditure (EE). For the cognitive dimension, psychophysiological indicators and the Knowledge Work Intensity index were employed. Results showed that warehouse assistants had an EE exceeding their PWC, indicating physical overload. Additionally, moderate mental workload was identified in TATM and TEC positions, with two or more affected indicators. It is concluded that specific ergonomic interventions are needed, including reorganization of work schedules and the implementation of ergonomic training programs. Furthermore, it is recommended to develop institutional policies that prioritize workers’ physical and cognitive well-being as part of a comprehensive prevention strategy.

Pulpectomy is the treatment of choice for primary teeth with severe pulp involvement, aiming to maintain the health of oral tissues and preserve the space for the permanent dentition. Rotary instrumentation is considered a technique currently used in primary dentition, as it allows for better adaptation to the shape of the canals, facilitates irrigation and subsequent obturation, reduces operative time, and improves pediatric patient cooperation during treatment.The objective of this study was to describe the clinical management of a pulpectomy in a primary tooth using rotary instrumentation in a pediatric patient. This case report presents the treatment of a primary first molar diagnosed with pulp necrosis, in which a pulpectomy with rotary instrumentation was performed. The Endo Kids system with Ni-Ti rotary files was used, irrigation was performed with sodium hypochlorite, and obturation was carried out using a calcium hydroxide and iodoform-based paste. A stainless-steel crown was placed as the final restoration, and three follow-up evaluations were conducted after the procedure.This case demonstrates the effectiveness of pulpectomy treatment using rotary instrumentation in primary teeth, showing both clinically and radiographically a good quality of obturation and canal sealing, and allowing for the preservation of the tooth in the oral cavity without infectious processes that could compromise the patient’s overall health.

Currently, globalization highlights the growing interest in understanding the factors that influence students' choice of STEM careers. Factors such as self-efficacy and choice actions play a decisive role in professional decision-making. The objective of this article was to identify the existing literature on the relationship between self-efficacy and choice actions among students selecting STEM disciplines. A literature search was conducted in five databases: SciELO, Redalyc, DOAJ, SCOPUS, and Google Scholar, using thesauri and Boolean operators in both Spanish and English. 72.5% of the studies included in this article were published between 2020 and 2023, with the United States leading in the number of investigations, followed by China and Mexico. Most of the research focused on the university level, identifying key variables such as attitude, outcome expectations, and intrinsic motivation. Findings indicate that students with higher self-efficacy are more likely to choose and persist in STEM disciplines. It is concluded that there is a significant research gap concerning high school and secondary school students, particularly in Mexico, suggesting the need for further studies at these educational levels.

Nursing professionals play a fundamental role in healthcare; therefore, their educational training requires the promotion of skills such as critical thinking and meaningful learning. However, traditional teaching methods fail to adequately prepare nursing students to meet the demands of a clinical environment. This study aims to determine the relationship between teaching strategies and meaningful learning among nursing students at a university in the Peruvian Amazon. It was a descriptive and correlational cross-sectional study, with a randomly selected sample of 108 students. Two validated questionnaires were used to measure teaching strategies and meaningful learning. Descriptive and inferential statistics were applied, utilizing Kendall's Tau-b test and Pearson's Chi-square test. The results showed that 27.8% of students in the high level of meaningful learning achieved the expected outcome, while 26.9% at the medium level were in the process stage. No significant relationship was found between teaching strategies and meaningful learning (p>0.05), nor with variables such as gender, age, or academic cycle (p>0.05). The findings highlight the need to update pedagogical strategies and incorporate clinical simulations and educational technologies to enhance students' preparation for professional nursing practice.

Effective communication management with students and stakeholders, along with the proper handling of documented information, are critical components of educational management systems aimed at enhancing institutional quality, promoting transparency, and ensuring informed decision-making. This study aims to establish a communication strategy and a procedure for managing documented information within the postgraduate program offered at the Center for Biomaterials at the University of Havana. A qualitative action-research design was employed to analyze document management through a single case study, incorporating document analysis techniques such as thematic content analysis and data triangulation from various sources. Additionally, an analysis of the institutional context was conducted to identify gaps and propose improvements. Clear objectives for communication with target audiences were established, identifying the most suitable media and designing methods for the continuous evaluation and enhancement of communication management. With regard to documented information, specific measures were implemented for its digitalization, improving both its accessibility and handling. The developed strategy enhanced the institution's capacity to manage communication and documentation effectively, contributing to the improvement of educational quality in postgraduate programs and preparing the organization for the future certification of its management system for educational institutions.

La fragmentación y segregación urbana son fenómenos complejos que surgen como resultado de procesos de planificación urbana, dinámicas sociales, económicas y políticas. Estos conceptos se relacionan estrechamente, pero tienen características específicas que merecen ser analizadas desde la perspectiva de la planificación de las ciudades. El objetivo de este artículo es analizar las dinámicas de fragmentación y segregación urbana en América Latina, con la finalidad de determinar sus causas, consecuencias y el impacto de las políticas de planificación urbana en estos procesos. A través de una revisión de fuentes académicas y un análisis crítico de casos de estudios relacionados con metropolización y expansión urbana de ciudades representativas de la región, se analizó cómo la estratificación social y las barreras físicas y simbólicas moldean el uso del suelo y perpetúan las desigualdades urbanas. Los resultados de este estudio revelan que la planificación urbana, lejos de ser una solución, intensifica la exclusión social y territorial, consolidando patrones de segregación. Frente a ello, se proponen estrategias orientadas a fomentar la diversidad socioeconómica, garantizar la provisión equitativa de servicios básicos, crear espacios públicos accesibles y promover la movilidad social, con el fin de construir ciudades más inclusivas, sostenibles y equitativas.
