OBTENCIóN DE RESULTADOS ORGANIZACIONALES A TRAVéS DE LA HISTORIA ADMINISTRATIVA
WILLIAM OSPINA GARCéS
Scientia Et Technica , 2004,
Abstract: El presente artículo presenta en una primera entrega, las diferentes teorías administrativas clásicas con un enfoque a RESULTADOS. Busca responder el interrogante: Cómo ha manejado la administración en las diferentes épocas, el problema de obtención de RESULTADOS ORGANIZACIONALES, según el contexto, los problemas y las circunstancias especificas que debieron ser resueltos y abordados.
Diagnóstico molecular de candidemia mediante PCR semianidada en pacientes críticos
Ospina,William Pascual; Cortés,Jorge Alberto;
Acta Medica Colombiana , 2011,
Abstract: objectives: to standardize a molecular test based on semi-nested pcr for diagnosis of candidemia. methods: we developed a pilot study by means of optimizing the extraction protocol and use of ribosomal dna, amplifying the complete its-2 region of candida spp. and by semi-nested pcr reamplifying specific segments of nine clinically relevant candida species. clinical samples of plasma of critically ill patients with microbiologically proven candidemia from a third level hospital in bogotá. another sample of simulated candidemia was used with candida strain form a urine sample. results: we were able to standardize this technique and achieved from clinical samples of plasma a likely sensitivity of 90% and a theoretical specificity of 100%. the detection capability of this test is up to 1 cell per 200 μl of plasma. conclusion: a molecular test for detection of candidemia among critically ill patients was standardized (acta med colomb 2011; 36: 135-140).
Consideraciones sobre el sentido de un proyecto educativo en Contaduría Pública
Rojas Rojas,William; Ospina Zapata,Carlos Mario;
Cuadernos de Administración (Universidad del Valle) , 2011,
Abstract: this document outlines how from the educational projects in public accounting, it is necessary to establish the iconographies and strategies which will support the pedagogical activities oriented towards the construction of an academic community which understands the need for a political formation engaged with the development of the individuality and with the main problems of the society. it points out that the conception of accounting that will support the current accounting formation should look beyond the reductionist, technical and mechanist view, to give way to modern conceptions, in contexts of globalization complexity and sustainability. it distinguishes that the educational purpose concreted in the interactions of the college academic life, is constituted in a powerful education device which allows the student to learn to think dialectically and meaningfully the reality of their time (political, social, cultural, economic context). finally, some criteria are succinctly outlined such as the curricular, pedagogical, didactic, evaluative criteria; notions that are foundational to materialize an educational project in public accounting.
Diagnóstico molecular de candidemia mediante PCR semianidada en pacientes críticos Molecular diagnosis of candidemia by seminested PCR in critically ill patients
William Pascual Ospina,Jorge Alberto Cortés
Acta Medica Colombiana , 2011,
Abstract: Objetivos: estandarizar una prueba molecular basada en PCR semianidada para el diagnóstico de candidemia Metodología: se desarrolló un estudio piloto en que se optimizó el protocolo de extracción y utilización de ADN ribosomal, amplificando la región ITS-2 completa de Candida spp. Y mediante PCR semianidada, reamplificando segmentos específicos de nueve especies clínicamente relevantes de Candida. Se utilizaron muestras clínicas de plasma de pacientes críticamente enfermos con candidemia documentada microbiológicamente del Hospital de la Samaritana en Bogotá. Se utilizó una muestra de candidemia simulada utilizando una cepa de Candida obtenida de orina. Resultados: se logró protocolizar dicha técnica y tener a partir de muestras clínicas de plasma una sensibilidad probable de 90% y especificidad teórica cercana a 100%. La capacidad de detección de este ensayo es hasta de una célula por 200 μl de plasma. Conclusiones: se estandarizó una prueba molecular para detección de candidemia en pacientes críticamente enfermos (Acta Med Colomb 2011; 36: 135-140).

THORACIC AND LUMBAR MENINGOCELE ASSOCIATED WITH NEUROFIBROMATOSIS TYPE 1.
Arciniegas William,Ospina-Ramirez Juan Jose,Ruiz Victor Hugo
Investigaciones Andina , 2010,
Abstract: Introduction: this is the service of internal medicine at San Jorge University Hospital, the case of a patient of 48 years with a diagnosis of neurofibromatosis type 1. Who had symptoms of 3 months of dyspnea, chest pain, and left little cough.Methods and results: we find in the chest CT scan left intrathoracic cyst corresponding to a lateral thoracic meningocele associated with multiple malformations of spine andplexiform neurofibromas, simultaneously, presenting a posterior sacral meningocele, both with progressive growth for six years.Discussion: the meningocele is a rare disease usually associated with neurofibromatosis type 1. Few cases described in the literature and sacred synchronous intrathoracic meningocele.

Proceso de confirmación metrológica dentro de una organización productiva
MARCELA BOTERO A,WILLIAM ARDILA U,LUZ MARíA OSPINA G
Scientia Et Technica , 2008,
Abstract: En este artículo se describe paso a paso el proceso de confirmación metrológic que debe tener implementado cualquier organización productiva, para evitar la utilización de equipos de medición que se encuentren funcionando por fuera de sus especificaciones y así reducir costos derivados de la fabricación de productos defectuosos.
CAPITAL HUMANO Y CONOCIMIENTO Retos para la Empresa del Siglo XXI
WILLIAM OSPINA GARCéS,LUZ STELLA RESTREPO,SANDRA ESTRADA MEJíA
Scientia Et Technica , 2004,
Abstract: El presente artículo se fundamenta en la importancia actual del denominado Capital Intelectual en el mundo empresarial contemporáneo. Parte de una rápida visión de los desarrollos que ha tenido el mundo de las organizaciones a partir de sus orígenes industriales, pasando por los problemas generados con la adopción de los modelos burocráticos tradicionales hasta llegar al concepto de la importancia del conocimiento en las diferentes esferas de la actividad económica.
