Diseño propuesta de mejora del sistema de seguridad y salud en el trabajo que permita disminuir los riesgos que presentan los trabajadores de la empresa Cooptransanmateo.

El presente proyecto de investigación se centra en la importancia que representa para una empresa la implementación de mejoras del SG-SST, se enfoca y aplica en la empresa Cooptransanmateo, la cual ejerce en función como prestadora de servicio de transporte público en el municipio de Soacha Cundinamarca. Se realizó una revisión bibliográfica acerca de temas relevantes para los puntos de investigación como: servicio de transporte público, condiciones, riesgos laborales, psicosociales, alteraciones de salud en los conductores, cada tema fue referenciado y citado; se limitó a la información que se relaciona directamente con el tema para su respectiva revisión y consulta, con el fin de comprender su relación directa con los objetivos establecidos. La metodología utilizada se basa en el método cuantitativo que permite tomar decisiones al analizar datos numéricos, estadísticas y permite responder a la pregunta de investigación e interpretar los resultados mediante gráficas y así categorizar las variables implementadas. Los datos obtenidos mediante la aplicación de una encuesta online al 40% al personal operativo de la empresa Cooptransanmateo identificaron las falencias en el sistema y las necesidades de los conductores por lo cual es recomendable proceder a tomar decisiones para realizar mejoras que promueva la protección de los conductores. Esto se realizará a través de programas, donde se da a conocer las situaciones a las cuales se exponen, actividades necesarias para salvaguardar el desarrollo de sus labores, capacitación constante acerca de las enfermedades más comunes y su prevención reportando siempre al área correspondiente dentro del interior de la empresa.This research project focuses on the importance that represents for a company the implementation of improvements in the OSHMS, focuses and applies in the company Cooptransanmateo, which serves as a provider of public transport service in the municipality of Soacha Cundinamarca. A bibliographic review was made about relevant topics for the research points such as: public transportation service, conditions, labor risks, psychosocial, health alterations in drivers, each topic was referenced and quoted; it was limited to the information directly related to the topic for its respective review and consultation, in order to understand its direct relation with the established objectives. The methodology used is based on the quantitative method that allows making decisions by analyzing numerical data, statistics and allows answering the research question and interpreting the results by means of graphs and thus categorizing the variables implemented. The data obtained through the application of an online survey to 40% of the operating personnel of the company Cooptransanmateo identified the shortcomings in the system and the needs of drivers so it is advisable to proceed to make decisions to make improvements that promote the protection of drivers. This will be done through programs, where it is made known the situations to which they are exposed, activities necessary to safeguard the development of their work, constant training about the most common diseases and their prevention, always reporting to the corresponding area within the company

Multi-messenger observations of a binary neutron star merger

On 2017 August 17 a binary neutron star coalescence candidate (later designated GW170817) with merger time 12:41:04 UTC was observed through gravitational waves by the Advanced LIGO and Advanced Virgo detectors. The Fermi Gamma-ray Burst Monitor independently detected a gamma-ray burst (GRB 170817A) with a time delay of ~1.7 s with respect to the merger time. From the gravitational-wave signal, the source was initially localized to a sky region of 31 deg2 at a luminosity distance of 40+8-8 Mpc and with component masses consistent with neutron stars. The component masses were later measured to be in the range 0.86 to 2.26 Mo. An extensive observing campaign was launched across the electromagnetic spectrum leading to the discovery of a bright optical transient (SSS17a, now with the IAU identification of AT 2017gfo) in NGC 4993 (at ~40 Mpc) less than 11 hours after the merger by the One- Meter, Two Hemisphere (1M2H) team using the 1 m Swope Telescope. The optical transient was independently detected by multiple teams within an hour. Subsequent observations targeted the object and its environment. Early ultraviolet observations revealed a blue transient that faded within 48 hours. Optical and infrared observations showed a redward evolution over ~10 days. Following early non-detections, X-ray and radio emission were discovered at the transient’s position ~9 and ~16 days, respectively, after the merger. Both the X-ray and radio emission likely arise from a physical process that is distinct from the one that generates the UV/optical/near-infrared emission. No ultra-high-energy gamma-rays and no neutrino candidates consistent with the source were found in follow-up searches. These observations support the hypothesis that GW170817 was produced by the merger of two neutron stars in NGC4993 followed by a short gamma-ray burst (GRB 170817A) and a kilonova/macronova powered by the radioactive decay of r-process nuclei synthesized in the ejecta
