Ingeniería e Investigación , 1992,
Abstract: Con el fin de garantizar que el café almacenado a granel conserve su calidad durante el tiempo necesario de almacenamiento, se estudió el enfriamiento del café pergamino seco en silos experimentales de dimensiones: 0.5m x 0.5m y 2.8 m de altura, utilizando aire enfriado mecánicamente. Los rangos estudiados fueron: temperatura de 10 a 220C humedad relativa de 66 a 98%y contenido de humedad del grano de 8 a 13.57% b.h. Durante la etapa de almacenamiento se evaluó la variación de la calidad del café según los criterios de coloración de la almendra, población de microorganismos y prueba de taza; paralelamente se dejaron muestras almacenadas en sacosa las condiciones de Chinchiná, como muestra testigo buscando determinar la bondad del almacenamiento a granel, también se dejó un silo sin aireación para determinar el efecto de la aireación controlada en la calidad del café.

Abstract: El tiempo libre es fundamental en la vida de cualquier individuo, no obstante, su beneficio o repercusiones, han sido poco explorados en el ámbito laboral y extralaboral de los trabajadores y en concreto, sobre el papel que tiene esta variable en la salud. El objetivo de este estudio fue determinar el efecto del tiempo libre en la salud y vida cotidiana de un grupo de operadores de carga, en función del uso activo o pasivo que hacen del mismo. Se realizó un estudio de prevalencia en 119 choferes foráneos. Se utilizó una metodología tanto cuantitativa como cualitativa, a través de una encuesta y cuatro entrevistas. Con los datos obtenidos, se efectuó un análisis descriptivo y de correspondencia. Se encontró que salir a pasear con la familia disminuía en 87% la posibilidad de presentar trastornos del sue o en los conductores (RP .13, IC .03-.63). Se conformaron cuatro conglomerados para ver la relación del tiempo libre con algunos da os a la salud. Destaca que el grupo que utilizaba de manera activa su tiempo libre, tiene menor probabilidad de presentar trastornos mentales, que aquellos que lo utilizaban de manera pasiva. La investigación permitió visualizar cómo la organización del trabajo y las exigencias a las que se someten estos trabajadores, repercuten en su salud y permean su vida cotidiana, por la cantidad de horas laboradas y el tiempo que pasan sin frecuentar a su familia.
