Factores de riesgo en construcción de edificaciones en el Valle de Aburrá

Un grupo de investigación en higiene y gestión ambiental del Politécnico Colombiano Jaime Isaza Cadavid, realizó un estudio para analizar el panorama de riesgos de 49 obras de construcción seleccionadas estadísticamente, estas están ubicadas en 10 municipios del área metropolitana del Valle de Aburra (Colombia) conformado por : Medellín, Sabaneta, Bello, Envigado, Itagüí, Caldas, La Estrella, Copacabana, Girardota y Barbosa, atreves del estudio de las condiciones de seguridad, donde el grupo aplicó métodos de ponderación, estrada y puerta con el fin de elaborar un panorama de riesgos detallado y preciso de las obras. La investigación arrojó información muy específica sobre los riesgos prioritarios en las obras de construcción, donde se encontró que el trabajo con mayor riesgo realizado es el trabajo en alturas con un valor del 84% presentado en las obras de construcción, de igual manera resaltan la priorización de los riesgos dado su alto nivel de repercusión o consecuencia. El ruido, los sobreesfuerzos, las temperaturas extremas, los movimientos repetitivos y las caídas de alturas son los más considerables y los más comunes que se presentan en las obras, por lo que se pretende analizar detalladamente el estudio realizado, con el fin de complementar aspectos relevantes que contribuyan a la investigación aportando información específica, análisis y conclusiones que propendan por la mejora continua en cuanto a los panoramas de riesgo, asociados a las obras de construcción, resaltando importancia que tiene la promoción y prevención de la salud sobre cualquier actividad realizada en las empresas de construcción.Universidad Libre Seccional Pereira -- Facultad de Ciencias de la Salud, Exactas y Naturales -- Especialización en Seguridad y Salud en el Trabajo, Gerencia y Control de RiesgosA research group in hygiene and environmental management of the Colombian Polytechnic Jaime Isaza Cadavid, carried out a study to analyze the risk panorama of 49 statistically selected construction works, these are located in 10 municipalities of the Valle de Aburra metropolitan area (Colombia) formed by: Medellín, Sabaneta, Bello, Envigado, Itagüí, Caldas, La Estrella, Copacabana, Girardota and Barbosa, through the study of security conditions, where the group applied weighting, road and door methods in order to develop a panorama of detailed and precise risks of the works. The investigation yielded very specific information on the priority risks in construction works, where it was found that the work with the highest risk performed is work at heights with a value of 84% presented in construction works, in the same way they highlight the prioritization of the risks given their high level of repercussion or consequence. Noise, overexertion, extreme temperatures, repetitive movements and falls from heights are the most considerable and the common that occurs during the works, so it is intended to analyze in detail the study carried out, in order to complement aspects that contribute to the investigation by providing specific information, analysis and conclusions that encourage continuous improvement in terms of risk scenarios associated with construction works, highlighting the importance of health promotion and prevention on any activity carried out in construction companies

Abundance and new records of sympatric owls in Manizales and Villa María (Caldas, Colombia)

Los estudios sobre abundancias de especies en comunidades de búhos neotropicales en ambientes urbanos y periurbanos son pocos. Entre mayo y septiembre de 2013 se estimó la abundancia relativa de búhos simpátricos, realizando conteos de llamados espontáneos a través de recorridos en trayectos, y se calculó el porcentaje de registros de cada especie en distintos tipos de vegetación, en cuatro localidades de Manizales (Caldas, Colombia). Además, se documentaron nuevos registros de ocho especies de búhos en 17 localidades en Manizales y Villamaría. En los recorridos se detectaron cuatro especies de búhos: Ciccaba virgata, Megascops choliba, Asio stygius y Tyto alba. Las especies registradas de mayor a menor abundancia relativa fueron: en La Esmeralda, A. stygius (0,37 No. ind./km recorrido), A. stygius, C. virgata y T. alba (0,02); en El Recinto del Pensamiento, C. virgata (0,37), A. stygius, A. stygius y T. alba (0,05), en El Bosque Popular El Prado, A. stygius (0,84), C. virgata y T. alba (0,03), y en El Ecoparque Alcázares, C. virgata (0,74) y A. stygius (0,10). C. virgata fue registrada en todos los tipos de vegetación, aunque el mayor número de registros de esta especie se obtuvo en los bosques asociados a áreas abiertas para la recreación. A. stygius fue registrada en cuatro tipos de vegetación, con un mayor número de registros en las áreas abiertas con árboles maduros. La baja sensibilidad a las perturbaciones por parte de C. virgata y A. stygius, y su adaptabilidad para ocupar un amplio número de ambientes podría favorecerlas para alcanzar los mayores niveles de abundancia entre los búhos de Manizales. A. stygius y T. alba se registraron con mayor frecuencia en las plantaciones de pino.Studies on species abundance of Neotropical owls in urban and peri-urban environments are few. Between May and September 2013, the relative abundance of sympatric owls in four localities of Manizales (Caldas, Colombia) was estimated by counting spontaneous calls through pre-established trails and calculating the percentage of recordings of each species in different types of vegetation. Furthermore, new records for eight owl species were documented in 17 localities of Manizales and Villamaría. Four owl species were detected in the trails: , and Tyto alba. The species recorded from high to low relative abundance were: in the locality of La Esmeralda, A. stygius (0.37 ind./km), A. stygius, C. virgata, and T. alba (0.02), in El Recinto del Pensamiento, C. virgata (0.37), A. stygius, A. stygius, and T. alba (0.05), in El Bosque Popular El Prado, A. stygius (0.84), C. virgata, and T. alba (0.03), and in El Ecoparque Alcázares, C. virgata (0.74), and A. stygius (0.10). C. virgata was recorded in all types of vegetation, although the greatest number of records for this species was obtained in forests associated with open recreation areas. A. stygius was recorded in four types of vegetation, with the greatest number of sightings in open areas with mature trees. The low sensitivity of C. virgata and A. stygius to perturbations and their adaptability to occupy a wide number of environments could put them at an advantage to achieve the highest levels of abundance among the owls in Manizales. A. stygius and T. alba were recorded with greater frequency in pine tree plantations

Diseño y construcción de un pedal de bicicleta basado en sensores piezorresistivos para determinar la fuerza resultante

En el ciclismo colombiano, las pautas de entrenamiento se ajustan a partir de datos cualitativos basados en la observación directa al deportista. Esta investigación busca mejorar ese proceso por medio de la implementación de pedales instrumentados para obtener datos cuantitativos del rendimiento del ciclista. En este artículo se presenta el diseño y construcción de un prototipo de dispositivo dinamométrico que permite la captura de datos de fuerza en el pedal durante el gesto del pedaleo. El dispositivo funciona con base en un sensor de fuerza piezorresistivo (FlexiForce®) acoplado a un arreglo mecánico específico y a un sistema de acondicionamiento de señal que entrega un voltaje proporcional a la fuerza ejercida, cuyo registro y análisis se realiza por medio de LabVIEWTM. El dispositivo permite visualizar la fuerza del pedaleo en tiempo real.In the Colombian cycling, the training guidelines are adjusted from qualitative data based on the direct observation of the sportsman. The aim of this research was to improve this process by the implementation of instrumented pedals to collect quantitative data of the performance of the cyclist. In this article we present the design and construction of a prototype of a dynamometric device that allows the acquisition of force data in the pedal. The device works based in a piezoresistive force sensor (FlexiForce®) connected to a specific mechanical adjustment and a signal conditioning system that gives a proportional voltage to the exerted force, whose registry and analysis are made in LabVIEWTM. The device allows the visualization of the pedaling force in real time

DIET OF BARN OWL (TYTO ALBA), SPECTACLED OWL (PULSATRIX PERSPICILLATA) AND RUFOUS-BANDED OWL (STRIX ALBITARSIS) IN THE WESTERN ANDES OF COLOMBIA

Abstract · Dietary studies are one of the most developed research areas in biology and ecology studies of Neotropical owls, but most of these studies have focused on few species. Our study describes the diet of Barn Owl (Tyto alba), Spectacled Owl (Pulsatrix perspicillata), and Rufous-banded Owl (Strix albitarsis) in Jardin and Ciudad Bolivar, western Andes of Colombia. The diet of T. alba, based on 495 prey items consisted 98.6% of vertebrates, the main food items being rodents (66%) and shrews (21.4%). Out of 142 prey items identified from P. perspicillata fractured pellets, the main prey species were Artibeus lituratus (23.9%), Rattus norvegicus (21.8%), and Didelphis sp. (16.1%), species of small and medium-sized mammals that tolerate environmental changes and often live in urban areas. Pulsatrix perspicillata preyed also on at least 14 bird species including hummingbirds and migratory birds. Based on 165 prey items S. albitarsis consumed more invertebrates (57.7%) than vertebrates (42.3%). Among the insects, the main preys were Coleoptera beetles and Orthoptera crickets. Among the vertebrates, the main prey species included mammals such as Thomasomys aureus, Marmosops sp., Marmosa sp., and Reithrodontomys mexicanus. These scansorial species are likely to be vulnerable to aerial predators such as S. albitarsis which hunt from a perchs. According to standardized Levins index values T. alba was the most selective in its food habits, P. perspicillata had intermediate values, while S. albitarsis showed the least selective diet.RESUMEN · Dieta de la Lechuza Común (Tyto alba), el Búho de Anteojos (Pulsatrix perspicillata) y el Búho Ocelado (Strix albitarsis) en la cordillera Occidental de Colombia Los estudios sobre hábitos tróficos constituyen la línea de investigación más desarrollada dentro de la biología y ecología de los búhos Neotropicales, pero la mayoría de esos estudios se han centrado en pocas especies. El propósito de este estudio es describir la dieta de la Lechuza Común (Tyto alba), el Búho de Anteojos (Pulsatrix perspicillata) y el Búho Ocelado (Strix albitarsis), en Jardín y Ciudad Bolívar, cordillera Occidental de Colombia. Identificamos 495 presas consumidas por T. alba. Su dieta estuvo compuesta en un 98.7% de vertebrados, principalmente roedores (66%) y musarañas (21.4%). De 142 presas de P. perspicillata, las presas principales, Artibeus lituratus (23.9%), Rattus norvegicus (21.8%) y Didelphis sp. (16.1%), son especies tolerantes a los ambientes intervenidos y hacen parte de los ensamblajes de pequeños mamíferos encontrados en ambientes urbanos. Pulsatrix perspicillata consumió también al menos 14 especies de aves incluyendo colibríes y aves migratorias. En base a 165 presas S. albitarsis consumió más invertebrados (57.7%) que vertebrados (42.3%). Entre los insectos depredó en mayor porcentaje los ordenes Coleoptera y Orthoptera, mientras que entre los vertebrados predominaron los de hábitos escansoriales (Thomasomys aureus, Marmosops sp., Marmosa sp. y Reithrodontomys mexicanus). Estos vertebrados serían más vulnerables a depredadores aéreos como S. albitarsis, la cual caza desde perchas en árboles. De acuerdo a los valores obtenidos para el índice estandarizado de Levins, T. alba fue más selectiva en el consumo de las presas, seguida por P. perspicillata, mientras que S. albitarsis tiene la dieta menos selectiva

BREEDING BEHAVIOR OF A REINTRODUCED PAIR OF ANDEAN CONDOR (VULTUR GRYPHUS) IN THE CENTRAL ANDES OF COLOMBIA

Abstract · Between 1989–2013, 69 Andean Condors (Vultur gryphus) were reintroduced in eight sites in the Andes of Colombia. Due to the lack of monitoring programs, little is known about the ecology and biology of these reintroduced populations. We present the first observations on a reintroduced breeding pair. For 36 months, we examined the breeding behavior of a pair of condors in a nest cave in the central Andes of Colombia. In June 2013, we observed a chick of about 6–7 months of age in the nest cave. The most remarkable outcomes of these observations are (1) that females spend more time guarding the chick whereas (2) males focus on guarding the nest cave. While the chick was in the nest cave (80 h of observations), the female was present in the vicinity of the nest cave and attended the chick for a longer time period than the male. However, in the absence of a chick or eggs (880 h of observations), the male was observed more often in the vicinity of the nest cave than the female. Nevertheless, we found no significant differences in vigilance patterns between the sexes. Intraspecific interactions of the Andean Condor with other raptors in the area were recorded during the observation period of this study. We make some predictions on the timing of reproduction of condors based on this reintroduced pair in Colombia and compare them with those reported elsewhere. Tracking released populations of condors is essential to ensure the positive impact of reintroduction efforts. Resumen · Comportamiento reproductivo de una pareja reintroducida de Cóndor Andino (Vultur gryphus) en la cordillera Central de Colombia Entre 1989–2013, 69 individuos de Cóndor Andino (Vultur gryphus) fueron liberados en ocho núcleos de repoblación en la región andina de Colombia. Debido a la falta de seguimiento de estas liberaciones, se conoce poco sobre la biología y ecología de la especie en esos núcleos de repoblación. Presentamos la primera información de seguimiento del comportamiento reproductivo de una pareja en los núcleos de repoblación. Por un periodo de 36 meses examinamos el comportamiento reproductivo de esa pareja en un nido encontrado en la cordillera Central de Colombia. En junio de 2013 registramos la presencia de un polluelo de aproximadamente seis a siete meses de edad en el nido. Mientras el polluelo estuvo en el nido (80 h de observación), la hembra permaneció dentro de la vecindad e interactuó por más tiempo con el polluelo en comparación con el macho. En ausencia de polluelo o postura (880 h de observación), el macho permaneció dentro del territorio por un mayor número de horas en comparación con la hembra, aunque estas diferencias no fueron estadísticamente significativas. Registramos interacciones interespecíficas directas entre el Cóndor Andino y rapaces que ingresaron a su área de anidación. El seguimiento de las poblaciones de cóndor liberadas es clave para garantizar el impacto positivo de los esfuerzos de reintroducción como herramienta para la conservación

FEEDING HABITS OF THE STYGIAN OWL (ASIO STYGIUS) AND THE SHORT-EARED OWL (A. FLAMMEUS) IN THE SOUTHWEST OF BOGOTÁ SAVANNA, CUNDINAMARCA, COLOMBIA

This study quantitively compares the diets of the Stygian Owl (Asio stygius) and the Short-eared Owl (A. flammeus) in the south-west of the Bogotá Savanna, Colombia. We identified 130 prey items from 111 A. stygius pellets and 579 prey items from 149 A. flammeus pellets. In terms of the numbers of preys, the diet of A. stygius consisted of the following: 88.1% birds, mainly pigeons, rails and cuckoos; and a smaller proportion of beetles (11.4%). In the diet of A. flammeus, insects were the most frequent prey item (59.8%), followed by rodents (39.8%), and birds (0.5%). In terms of biomass contribution, the main preys in the diet of A. stygius were Eared Doves (Zenaida auriculata) (54%) and Purple Gallinules (Porphyrio martinica) (19.3%), while the diet of A. flammeus consisted mainly of House Mice (Mus musculus) (65.2%). Diet diversity varied between the owl species: A. flammeus was more selective in its hunting habits, while A. stygius was more of an opportunistic predator. It is important to quantify the ecosystem services these owls provide not only by controlling M. musculus, Z. auriculata, and Shiny Cowbird (Molothrus bonariensis) populations, which can affect human well-being and threatened species populations, but also through secondary seed dispersion and birdwatching opportunities

Human-raptor conflict in rural settlements of Colombia.

In human-transformed landscapes, predators may feed on domesticated animals, and thus affect human well-being, creating negative perceptions and leading to conflict with people that can result in the persecution of the predator. We studied the factors that influence the perception of the Black-and-chestnut Eagle (Spizaetus isidori) in four rural Andean communities in Colombia and compiled historical and recent evidence on the persecution and other causes of mortality of this species in the country. We applied 267 questionnaires and conducted 16 interviews with local inhabitants, via visits to homes and schools in the surroundings of S. isidori nests. The perception of S. isidori by the inhabitants was largely negative and influenced by different socio-demographic factors such as gender, chicken (Gallus gallus) ownership, and chicken management. The records we obtained indicate that 47 eagles were shot, 16 were captured (three for illegal trafficking) and two were electrocuted on high-tension wires. The persecution of S. isidori occurs as retaliation or as a preventative measure against chicken predation, and is a significant cause of mortality of this species in Colombia. Effective conservation planning for S. isidori in Colombia needs to go further than the protected areas system, and include a socioecological perspective in conservation practices applied at landscapes scales that are dominated by people. Education programs and socioecological research, along with participatory work in local communities are key to the conservation of S. isidori in breeding territories. This approach can also prevent conflict over food resources-G. gallus and other poultry-that are shared by humans and S. isidori in rural landscapes
