Abstract Introduction: The use of point-of-care ultrasound (PoCUS) has gained relevance in medical practice, improving diagnostic capacity and patient safety. However, in Uruguay, PoCUS training for internal medicine physicians is limited. The objective is to achieve the implementation of PoCUS training in Internal Medicine postgraduate courses. Methodology: A course-workshop was created divided into modules by clinical systems and protocols. Bibliography and audiovisual material were provided to participants. Wireless portable ultrasound machines and voluntary models were used. Diagnostic knowledge tests, structured objective clinical evaluations, and satisfaction surveys were conducted. Results: 30 of the 32 participants completed and passed the course. The satisfaction survey showed a high evaluation of the course objectives, logistics, and instructors. There was a statistically significant improvement in PoCUS knowledge between the pre and post test (54.72% vs. 82.5%). The final assessment had an average passing rate of 92%, with only one exception requiring retake. Discussion: PoCUS training in Internal Medicine is perceived as valuable, but its development is limited in Uruguay. The implementation of a structured course demonstrated improvements in knowledge and high levels of satisfaction. It was compared with other clinical skills courses with similar results. The learning curve for different organs varies, highlighting the need for continued monitoring. Conclusions: High levels of satisfaction were obtained from participants with positive knowledge and skills results. We believe that it is important to continue investigating the learning curve after the course.

Abstract Temporality in training processes is a topic rarely addressed in the bibliography. In this work, it asumes special interest in order to adresss the transformations that take place in trainers of trainers who undergo a training process. The work is part of a UBA research project in which 9 teacher trainers, participants in a clinical-type training device, are taken as key informants. From a qualitative and hermeneutic methodological strategy, the Constant Comparative Method (Strauss & Corbin, 2002) was applied in two moments: 1: final group meeting of the training workshop; 2: individual interviews with each participant one month later. The analysis creates a system of categories to record expectations, value judgments and transformations that they identify. In light of psychoanalytic concepts, hypotheses are developed that allow the concept of temporality to be prioritized in trainig processes.

Abstract The quarry-workshops are ancient lithic landscapes that are socially significant and traditional. The aim of this work was to analyze the technological activities and the persistent use of space in a quarry-workshop landscape in Antofagasta de la Sierra (Catamarca province, Argentina). For this purpose, techno-typological studies of lithic assemblages sampled in different sectors of the quarry-workshop landscape were carried out, together with an analysis of differential stages of eolian abrasion. The quarry-workshop landscape has activity areas under open sky and repair where core reduction, blank extraction and tool knapping were carried out. The presence of techno-technological diagnostic tools (e.g., bifaces, bifacial thinning flakes, preforms and projectile points) indicated the activities of hunter-gatherer groups that occupied the region in different time periods. On the other hand, the information from the different stages of eolian abrasion allowed a chronological approach to the knapping events that gave rise to this ancient landscape. In addition, the analysis of the differential stages of abrasion made it possible to recognize cases of artifact reclamation and the reuse of task spaces in a persistent way. In sum, the data recovered from the analysis of the lithic assemblages made it possible to confirm the continuous procurement of raw materials and the sustained use of space at different moments of the local time sequence. In fact, the conformation of this ancient social landscape occurred continuously from the early Holocene and early middle Holocene.

Resumen Las canteras-taller conforman paisajes líticos antiguos que son socialmente significativos y tradicionales. El objetivo de este trabajo fue analizar las actividades tecnológicas y el uso persistente del espacio en un paisaje de canteras-taller de Antofagasta de la Sierra (provincia de Catamarca, Argentina). Para tal fin se llevaron a cabo estudios tecno-tipológicos de conjuntos líticos muestreados en diferentes sectores del paisaje de canteras-taller, junto a un análisis de estadios diferenciales de abrasión eólica. El paisaje de canteras-taller cuenta con áreas de actividad a cielo abierto y bajo reparo donde se realizaron tareas de reducción de núcleos, extracción de formas-base y formatización de instrumentos. La presencia de artefactos tecno-tipológicamente diagnósticos (por ejemplo, bifaces, lascas de adelgazamiento bifacial, preformas y puntas de proyectil) dio cuenta de actividades de grupos cazadores-recolectores que ocuparon la región en diferentes lapsos temporales. Por su parte, la información reunida de los distintos estadios de abrasión eólica permitió efectuar una aproximación cronológica relativa a los eventos de talla que dieron origen a este antiguo paisaje. Además, el análisis de los estadios diferenciales de abrasión posibilitó reconocer casos de reclamación de artefactos y la reutilización de espacios de tareas de manera persistente. En suma, los datos recobrados del análisis de los conjuntos líticos posibilitaron constatar el aprovisionamiento continuo de materias primas y el uso permanente del espacio en diferentes momentos de la secuencia temporal local. En efecto, la conformación de este antiguo paisaje social se dio de manera sostenida desde el Holoceno temprano e inicios del Holoceno medio.

Abstract This paper presents the results of the archaeological research carried out at the quarry- workshop of Arroyo La Saudade locality. This study was aimed at characterizing the available raw material and the recovered archaeological assemblages. This locality is in the southwestern sector of the Ventania hilly system, in the southeast of the province of Buenos Aires, Argentina. It is associated to an outcrop of the Brecha Cerro Colorado unit, formed by good quality quartzite pebbles. On these pebbles, evidence of knapping for the extraction of raw material were detected as well as a large amount of spatially associated lithic artifacts. Two grids were excavated, and surface collections were made. On the recovered lithic assemblage, macroscopic (to characterize its colour and fracture), microscopic (through petrographic microscope) and techno-morphological analysis were conducted. Quartzite from this locality is distinguished, under a microscope, by the presence of a variable, but generally very low, degree of metamorphism, good quality for knapping, and smooth, shiny fracture surfaces. The colours are presented in a limited range, with predominance of ochre and pink. Among the recovered artifacts are cores in different stages of reduction and preparation, tools, and flakes. Some implications of these findings are discussed.

Resumen En este trabajo se presentan los avances en las investigaciones desarrolladas en la localidad cantera-taller Arroyo La Saudade, las cuales estuvieron orientadas a caracterizar la materia prima disponible y los conjuntos arqueológicos recuperados. Dicha localidad se ubica en el sector suroccidental del sistema serrano de Ventania, en el sudoeste de la provincia de Buenos Aires, Argentina. Se encuentra asociada a un afloramiento de la unidad Brecha Cerro Colorado, conformado por rodados de cuarcita de buena calidad para la talla. Sobre estos rodados se identificaron evidencias de talla para la extracción de materia prima, así como una gran cantidad de artefactos líticos en las inmediaciones. Se excavaron dos cuadrículas y se realizaron recolecciones superficiales. Sobre los artefactos recuperados se desarrollaron análisis macroscópicos (a los fines de caracterizar su color y fractura), microscópicos (por medio de microscopio petrográfico) y tecno-morfológicos. Las cuarcitas de esta localidad se distinguen, bajo microscopio, por la presencia de rasgos que denotan un grado variable de metamorfismo, pero generalmente muy bajo, una buena calidad para la talla y superficies de fractura lisas y brillantes. Se presentan en una gama acotada de colores, con predominio de los ocres y rosados. Entre los artefactos recuperados se encuentran núcleos con diferente grado de reducción y preparación, instrumentos y productos de talla. Se discuten algunas implicancias de estos hallazgos.

Abstract This paper presents the analysis of chert and orthoquartzite cores recovered from quarry- workshop sites located in the northwestern sector of Tandilia, Buenos Aires province. The main goal is to determine the knapping methods used to reduce the cores as well as to identify the débitage (flaking) types used on each rock. Considering the volumes and morphologies of the cores that were reduced, the selected technical criteria and production objectives are analyzed. In this sense, different objectives related to obtaining blanks represented by modules of different dimensions and thicknesses were identified. In turn, natural and prepared platforms were observed, as well as pieces with unidirectional, bidirectional, and multidirectional extractions. There is a great variability in the degree of reduction of the cores, some of which are scarcely used and others exhausted, including bipolar pieces. These studies allowed us to recognize different modes in the exploitation of both rocks that are mainly related to the way in which they occur naturally in the outcrops.

Resumen En este trabajo se presenta el análisis de núcleos de ftanita y ortocuarcita recuperados en sitios cantera-taller ubicados en el sector noroccidental de Tandilia, provincia de Buenos Aires. El objetivo principal es determinar los métodos de talla utilizados para la reducción de los núcleos e identificar los tipos de débitage empleados sobre cada roca. Considerando los volúmenes y morfologías de los núcleos que fueron reducidos, se analizan los criterios técnicos seleccionados y los objetivos de producción. En este sentido, se identificaron distintos objetivos vinculados con la obtención de soportes representados por módulos de diferentes dimensiones y espesores. A su vez, se observaron plataformas de percusión naturales y preparadas, así como piezas con extracciones unidireccionales, bidireccionales y multidireccionales. Se registró gran variabilidad en el grado de reducción de los núcleos, algunos de los cuales se encontraban escasamente desbastados y otros agotados, incluyendo piezas bipolares. Estos estudios permitieron reconocer diferentes modos en la explotación de ambas rocas, que se relacionan principalmente con la forma en que se presentan naturalmente en los afloramientos.

BACKGROUND: Community health workers' knowledge, skills and training seem to affect their contribution to 4th-year health sciences student teams who are following an interprofessional learning programme aimed at improving two South African rural communities' health outcomes related to diabetes OBJECTIVE: To develop a framework for community health workers to contribute to interprofessional learning teams METHODS: The framework development forms part of previous phases of a multi-method study. The theory of change logic model guided the development of the draft framework, informed by data from two ecogram sessions, five nominal group technique discussions and a scoping review. The final framework was validated by experts during a workshop using forward and backward mapping RESULTS: The framework addresses the need for community health workers to gain knowledge, skills and training related to diabetes to effectively contribute to interprofessional learning teams. The theory of change process identified community needs and assets, desired results, influential factors, evidence-based strategies and assumptions required to address the problem CONCLUSION: The framework focuses on a problem within specific interprofessional learning teams. Collaboration with stakeholders contributed to a rigorous research process, and the validation, refinement and future implementation of the framework. The framework eventually led to the development of an evidence-based training programme comprising knowledge, skills and training strategies related to diabetes. It is predicted that once community health workers have completed this training programme, they will be able to contribute effectively to the interprofessional learning teams

BACKGROUND: Despite benefits, structured mentorship needs to be better recognised within health profession training institutions (HPI) in Southern Africa (SA). Given the need to transform faculties and retain skilled personnel, mentoring programmes can be used to address these needs and warrant further exploration OBJECTIVE: To explore mentorship models within HPI in SA METHODS: During the annual South African Health Educationalists Conference (SAAHE) in 2022, five academics from HPIs in the region conducted an interactive national workshop on mentorship in health professions education. Following a presentation on mentorship models, participants were allowed to share their perspectives on current mentorship practices, gaps and recommendations for enhancing mentorship. Key concepts and themes generated are reported RESULTS: Three key approaches to mentorship models were identified during the workshop. These were 'top-down', 'ad-hoc' and 'supportive' approaches. Mentorship models were largely self-initiated and followed a traditional dyadic style with little innovation. Mandatory 'top-down', over-regulated programmes compared with 'grassroots' approaches were the two extremes reflected on the spectrum of models. While the benefits of mentorship were recognised, institution-wide implementation is lacking, reflecting varied or no widescale adoption. Mentorship could serve as a focused, formal strategy to ensure the demographic transformation of HPIs. Recommendations were made to measure the effectiveness of mentorship programmes against academic promotion criteria and research outputs CONCLUSION: While mentorship is positively viewed as a means to ensure improved equity and outputs, practical implementation is lacking. Mentorship programmes require further exploration of models and processes to facilitate successful implementation

ABSTRACT The design and visualization of the distribution of atoms in a fraction of space through the application of software allows us to increase the understanding of the structure of materials and the elaboration of theoretical propositions. The purpose of this work was to develop a procedure for the application of the GeoGebra 3D software as a tool for designing crystalline structures, from the Mathematics subject for Chemical Engineering students.

ABSTRACT The present study focuses on vibration exposure and its impact on occupational health, contrasting the results with previous research. Workers in a specific workshop were investigated, assessing their vibration exposure, working hours and risk perception. A mixed approach was used, collecting data through structured surveys and inferential statistical analysis. The results indicate that 80% of the workers are exposed to vibration to some extent, with 10% exposed half the time and 6% almost always. However, no significant correlations were found between vibration exposure and other factors such as musculoskeletal health or reduced work activity. These discrepancies with previous research suggest demographic and occupational variations among the samples studied. It is concluded that it is critical to address musculoskeletal health in a comprehensive manner, implementing effective control measures to prevent mechanical vibration-related injuries.

Research methods taken into account were: analysis-synthesis, inductive-deductive, theoretical modeling, documentary analysis, survey and interview, which made it possible to achieve the objective. The planning and design of the workshop program is part of the results, which also reflects the relevance of Corporal Expression from its multiple dimensions as a proposal that contributes to the improvement of the teaching-learning process and recreational spaces for children. Its implementation is from the University Extension as a summer course and constitutes a recreational alternative that has no precedent in the Cuban Sport University.
