Este reto también exige al sector de la construcción, la implementación de nuevas tecnologías de información y herramientas digitales como estrategia efectiva para la captura de datos confiables que contribuyan en mejorar indicadores de productividad, seguridad y calidad. Particularmente en este trabajo se presenta una propuesta para la generación de valor en proyectos de construcción, a través del uso de tecnologías para captura de información digital que permiten hacer una reingeniería de procesos constructivos a través de la implementación de la filosofía Lean Construction y la simulación digital. Inicialmente se presenta el diseño y desarrollo de un módulo programable y autónomo para captura de imágenes digitales de procesos constructivos, con alimentación a través de energía fotovoltaica. Se incluyen equipos de hardware y componentes electrónicos como cámaras fotográficas, cámaras de video, tarjetas electrónicas, computadores, paneles solares, plataforma web y sistemas de comunicación; controlados a través de un software diseñado específicamente para este fin, que facilita el control de equipos y componentes. Este sistema facilita la toma de decisiones respecto a métodos constructivos y recursos involucrados, con el fin de minimizar el costo y aumentar los rendimientos. En la segunda parte del documento se presentan los resultados obtenidos de la implementación del módulo en la construcción de un proyecto de edificación en la ciudad de Bogotá, Colombia. El documento incluye el análisis de la información obtenida, la caracterización de procesos constructivos utilizando videos Time-Lapse y la realización de un modelo de simulación digital del proceso constructivo. Los resultados obtenidos, permiten reducir tiempos de ciclo y dar un mejor uso a los recursos, representando ahorro de recursos para el proyecto.

In this context, the precise characterization of circulating viruses is of utmost importance. This work describes the first molecular epidemiology study performed with the complete VP(1)-coding region of 114 field isolates of FMD virus (FMDV) type O, collected in the Andean countries mainly during 2002-2008. Sequences were aligned and compared to isolates responsible for emergencies in the Southern Cone of the continent between the years 2000 and 2006, and to other representative type O viruses worldwide. The results showed that FMD type O viruses isolated in South America and analyzed up to date are placed in 11 different lineages within the Euro SA topotype. Five of these lineages included viruses circulating in Ecuador and Venezuela during 2002-2008. The last emergencies reported in already-free areas in the Andean region, showed close relationships with viruses circulating in these endemic countries. Andean lineages showed a clear separation from the unique lineage containing viruses responsible for the emergencies in the Southern Cone, reflecting the different livestock circuits and providing evidence that support the ecosystem dynamics in the region. A wide geographical dissemination of the same strain in short time intervals has been observed, pointing to animal movements as the most significant risk parameter. This fact, together with an important generation of viral variants in areas under weak control strategies, reinforce the need of stronger official controls, as well as for establishing multinational cooperative measures in the border areas.
