This study proposes for organizations with intensive use of knowledge, a model that predicts the employees´ mobility intentions, which includes not only the perceptions that employees have of extrinsic and intrinsic rewards received, and perceived organizational support to human capital, but also introduces the opportunity cost of the employee, as moderator of the relationship between rewards and intention to leave the organization. The data used was collected from different public and private universities in Colombia. The global model allows to proof of the existence of negative correlations between the exogenous constructs and the endogenous construct, as well as knowing the opportunity cost moderation in relations between the rewards described and intention to leave the organization. Findings suggest that in organizations with intensive use of knowledge, the perceptions that knowledg...

Describe los factores más frecuentemente asociados a infecciones intrahospitalarias en el Centro Medico Naval. Determina cuál es el agente causal más frecuente de infecciones intrahospitalarias (IIH). Se utilizó el método de muestreo no aleatorio continuo para todos los casos encontrados con infección intrahospitalaria a través de la revisión de las fichas de vigilancia y las historias clínicas de los casos notificados. La población de estudio está constituida por pacientes hospitalizados en áreas críticas del Centro Médico Naval durante el periodo enero 2002 a diciembre 2006. Se revisaron las historias clínicas y las fichas de vigilancia de IIH, de los pacientes que presenten Infección Intrahospitalaria en las áreas críticas en el periodo de estudio y la información necesaria de cada caso será recolectados mediante una ficha de recolección de datos estructurada. Enc...

El problema de acelerar el fraguado y endurecido de los aglomerantes hidráulicos y en particular del cemento portland es muy antiguo; se ha tratado de resolver por medios más diversos, desde el puramente físico como el calentar los óxidos y el agua de acabado antes de efectuar la mezcla de ellos. Otro medio de acelerar el fraguado y endurecido más aplicable en piezas prefabricadas, consiste en someter a estos a un tratamiento de vapor. Con el transcurso del tiempo esta técnica de acelerar el fraguado y endurecido del concreto fue mejorando, aparecieron los medios químicos que se fundan en los efectos causados por determinadas adiciones en cantidades adecuadas. Los estudios realizados en países donde la técnica de los concretos está altamente desarrollada, dan como resultados que los concretos elaborados a base de aditivos dan ciertas propiedades beneficiosas en cuanto a calidad...

Between 1962 and 1980, the Departments of Gynecology and Medical Oncology INEN have handled 170 cases of trophoblastic disease. All patients had clinical and / or radiographic evidence and hormonal disease activity; histopathologic evidence was obtained when the disease was accessible to biopsy. Half of the patients are in the third decade of life, and a quarter in the fourth decade; 8 percent were under 20 years old. Only 27 percent of cases were under three months of sick time; in 21 percent of cases the disease duration was more than one year. 64.7% of cases had a history of mole, and 20 percent of abortion; in 10% of cases of history was normal delivery. Only 110 patients (64.75%) showed evidence of pelvic disease admission; 35% of 110 cases found evidence of disease in the pelvis. 55% of cases presented lung metastases, and 20% vulvovaginal metastasis; intestinal metastasis, liver o...
