Mirador Comedor Emergente

74 p.Mirador Comedor Emergente es un proyecto de Ctulo de la Escuela de arquitectura de la Universidad de Talca que trata de un comedor de temporeros para un predio agrícola de viñas y manzanos llamado Gajardo & Compañía, ubicado en el kilómetro 3 de la ruta J-- 665, del Camino El Maitén, Los Niches, Curicó. El comedor busca satisfacer una necesidad actual del campo, en donde los trabajadores actualmente almuerzan en el piso. Para ello se desarrolla este proyecto en busca de satisfacer a actual necesidad de los 15 trabajadores que trabajan las faenas de cosecha y vendimia del predio. Entonces, el principal objetivo del proyecto es lograr un buen comer, y solucionar la actual necesidad. Se busca lograr que los usuarios , mediante la obra logren reconocer el paisaje en donde se desempeñan desde otro punto lograr en cierta medida que escapen de la sensación de trabajo llegada al suelo que logren mediante el proyecto emerger por sobre el paisaje llegando así a un nuevo recon0cimiento del mismo. La obra fue concebida en base a materiales de deshecho reales, madera de bins de deshecho, retazos de alambre reciclado de replantaciones de parrones rocas sobrantes de procesos de defensas fluviales, y malla desechada de packins vecinos. El proyecto no se busca mas que satisfacer la necesidad de un buen comedor a través de la arquitectura y los medios contractivos utilizados por el campesin

Primeras Conclusiones de las Relaciones Entre los Proyectos Finales de Carrera, los Diseños Curriculares y Perfiles Profesionales de las Carreras en la UTN FRSF

Este trabajo es un análisis comparativo de los perfiles profesionales evidenciados en larelación entre los planes de estudio, las incumbencias y los proyectos finales de carrera, la cual fue analizada en trabajos anteriores para las carreras de Ingeniería Industrial, Civil y en Sistemas de Información, de la Universidad Tecnológica Nacional, Facultad Regional Santa Fe. Se pretende que los resultados obtenidos de esta auto-evaluación institucional contribuyan a repensar el perfil del ingeniero y reorientar contenidos curriculares, con un enfoque de mejora continua. Las conclusiones extraídas se sintetizan en que, en términos generales, los contenidos del currículo de cada carrera coincidieron con los reflejados en los proyectos finales. También se detecta que las carreras presentan tanto perfiles técnicos como de gestión. Por último, en los mismos se considera que podría ser mayor el análisis del impacto social en las temáticas desarrolladas

Functional differences found in the elderly living in the community

Introduction: Successful aging lies in cognitive and functional maintenance, and in the optimal performance of daily tasks that keep the elderly free of disability and dependence. However, there is little evidence for functional differences for gender and age, and how cognitive and physical demands in past working lives can affect them, to design more personalized occupational therapy interventions to prevent functional and cognitive impairment. Method: This observational descrip-tive study evaluated 367 older adults living in a community with subjective memory complaints and scored between 24 and 35 with the Spanish version of the “Mini-Mental State Examination (MEC-35)”. Basic activities of daily living (BADL) were studied with the Barthel Index, while instrumental ADL (IADL) were examined with the Lawton–Brody scale. Functional differences for gender, age, and physico-mental occupation were examined. Results: The significant differences found for gender indicated that men did better in BADL (p = 0.026) and women better performed IADL (p < 0.001). Differences between age groups suggest that the younger group (aged 64–75) obtained better results for BADL (p = 0.001) and IADL (p < 0.001). For physico-mental occupation, statistically significant differences were found only in IADL for mental (p = 0.034) and physical occupation (p = 0.005). Conclusions: Gender, age, and the cognitive and physical demands of occupational stages, can be important predictors of cognitive and functional impairment. These results can be generalized to other health centers in the province and to other Spanish Autonomous Communities because their socio-demographic variables are similar. It would be interesting to carry out multimodal personalized interventions that consider the factors that might affect functional impairment to preserve personal autonomy. © 2021 by the authors.

Controlled Anisotropic Deformation of Ag Nanoparticles by Si Ion Irradiation

The shape and alignment of silver nanoparticles embedded in a glass matrix is controlled using silicon ion irradiation. Symmetric silver nanoparticles are transformed into anisotropic particles whose larger axis is along the ion beam. Upon irradiation, the surface plasmon resonance of symmetric particles splits into two resonances whose separation depends on the fluence of the ion irradiation. Simulations of the optical absorbance show that the anisotropy is caused by the deformation and alignment of the nanoparticles, and that both properties are controlled with the irradiation fluence.Comment: Submitted to Phys.

Klebsiella pneumoniae Strains Producing Extended-Spectrum B-Lactamases in Spain: Microbiological and Clinical Features

Extended-spectrum B-lactamases (ESBL) of the CTX-M, SHV, and TEM families were recognized in 76 (67%), 31 (27%), and 6 (5%) isolates, respectively, among 162 ESBL-producing Klebsiella pneumoniae (ESBLKp) strains obtained in a multicenter study in Spain. Predisposing factors for ESBL-Kp acquisition included invasive procedures, mechanical ventilation, and previous antimicrobial use

Randomized controlled trials and real-world observational studies in evaluating cardiovascular safety of inhaled bronchodilator therapy in COPD

Long-acting muscarinic antagonist (LAMA) or long-acting β2-agonist (LABA) bronchodilators and their combination are recommended for the maintenance treatment of chronic obstructive pulmonary disease (COPD). Although the efficacy of LAMAs and LABAs has been well established through randomized controlled trials (RCTs), questions remain regarding their cardiovascular (CV) safety. Furthermore, while the safety of LAMA and LABA monotherapy has been extensively studied, data are lacking for LAMA/LABA combination therapy, and the majority of the studies that have reported on the CV safety of LAMA/LABA combination therapy were not specifically designed to assess this. Evaluation of CV safety for COPD treatments is important because many patients with COPD have underlying CV comorbidities. However, severe CV and other comorbidities are often exclusion criteria for RCTs, contributing to a lack in external validity and generalizability. Real-world observational studies are another important tool to evaluate the effectiveness and safety of COPD therapies in a broader population of patients and can improve upon the external validity limitations of RCTs. We examine what is already known regarding the CV and cerebrovascular safety of LAMA/LABA combination therapy from RCTs and real-world observational studies, and explore the advantages and limitations of data derived from each study type. We also describe an ongoing prospective, observational, comparative post-authorization safety study of a LAMA/LABA combination therapy (umeclidinium/vilanterol) and LAMA monotherapy (umeclidinium) versus tiotropium, with a focus on the relative merits of the study design

Determination of the respiratory compensation point by detecting changes in intercostal muscles oxygenation by using near-infrared spectroscopy

This study aimed to evaluate if the changes in oxygen saturation levels at intercostal muscles (SmO2-m.intercostales) assessed by near-infrared spectroscopy (NIRS) using a wearable device could determine the respiratory compensation point (RCP) during exercise. Fifteen healthy competitive triathletes (8 male; 29±6 years; height 167.6±25.6 cm; weight 69.2±9.4 kg; V ̇O2-máx 58.4±8.1 mL·kg-1·min-1) were evaluated in a cycle ergometer during the maximal oxygen-uptake test (V ̇O2-máx), while lung ventilation (V ̇E), power output (watts, W) and SmO2-m.intercostales were measured. RCP was determined by visual method (RCPvisual: changes at ventilatory equivalents (V ̇E·V ̇CO2-1, V ̇E·V ̇O2-1) and end-tidal respiratory pressure (PetO2, PetCO2) and NIRS method (RCPNIRS: breakpoint of fall in SmO2-m.intercostales). During exercise, SmO2-m.intercostales decreased continuously showing a higher decrease when V ̇E increased abruptly. A good agreement between methods used to determine RCP was found (visual vs NIRS) at %V ̇O2-máx, V ̇O2, V ̇E, and W (Bland-Altman test). Correlations were found to each parameters analyzed (r=0.854; r=0.865; r=0.981; and r=0,968; respectively. p<0.001 in all variables, Pearson test), with no differences (p<0.001 in all variables, t-student test) between methods used (RCPvisual and RCPNIRS). We concluded that changes at SmO2-m.intercostales measured by NIRS could adequately determine RCP in triathletes
