Flexibility and Academic Credits within Higher Education trends

La globalización en la Educación Superior y el nuevo marco de mercado dentro del sistema universitario ha introducido el concepto de flexibilidad. Uno de Ios instrumentos principales en el desarrollo de este proceso ha sido el Sistema de Crédito Académico (el Marco de Crédito), que es un modo de reestructurar el currículum hacia la Flexibilidad de Suministros. Muchos países en el mundo entero han introducido este modelo, después del Sistema de Crédito americano. Este trabajo explorará conceptualmente los eslabones entre las tendencias principales en la enseñanza superior y este nuevo concepto.Globalisation in Higher Education and the new market framework within the University System have introduced the concept of flexibility. One of the main tools in the development of this process has been the Academic Credit System (Credit Framework), which is a way of restructuring the curriculum towards Frexibility of Provision. Many countries around the world have introduced this model, following the American Credit System. This paper will conceptually explore the links between the main trends in higher education and this new concept.Fil: Restrepo Abondano, José Manuel. Universidad de Rosario (Colombia

Caracterización de la polarización de la respuesta inmune tipo LTCD+ TH1/Th2 en pacientes coinfectados con Helicobacter pylori helmintiasis, procedentes de áreas de bajo riesgo de desarrollar cáncer gástrico

Diferentes estudios han demostrado una alta prevalencia de infección por helmintos en la población colombiana coinfectada por Helicobacter pylori con un impacto en la respuesta inflamatoria del hospedero. La relación entre coinfección e inflamación sistémica es aún controversial. La infección por helmintos ha sido correlacionada con respuestas anti-inflamatorias aún en presencia de Helicobacter pylori (LTCD4+ Th2-IgG1). Esta investigación caracterizó el perfil de respuesta inmune a través de mediciones de interleuquinas en sangre periférica en pacientes coinfectados con helmintos y Helicobacter pylori.MaestríaMAGISTER EN CIENCIAS BIOMÉDICA

Irrigation canal models for automatic control purposes

volumes during normal canal operation. In order to develop control algorithms for irrigation canals there is a need for simple linear models to be used in the algorithms. The following simple linear models are approximating the canal in order to give a base to develop control algorithms. The PAC-UPC laboratory canal (Prueba de Algoritmos de Control - Universitat Politècnica de Catalunya) is modelled (input and output discharge) using the following three models: Muskingum, Hayami and Integrator Delay Zero (IDZ) and the results are compared to measurements. All three models are able to describe the irrigation canal in an acceptable way. However, only the IDZ model can capture all the important characteristics. These tested models can be applied to represent real canals for control purposes where it is especially important to obtain good models without extensive measurements. Test campaigns are developped now in cooperation with the CHE (Confederación Hidrográfica del Ebro) in order to test control algorithms to be used in irrigation canals under their management.Peer Reviewe

Nueva ruta de síntesis para el dióxido de titanio

Se obtuvo dióxido de titanio por medio de una nueva ruta de síntesis que combina la técnica solgel con reacción a presión autógena. Se ensayaron dos geles de síntesis con diferentes fuentes de titanio; una de ellas usó tetraisopropil ortotitanato empleando agua e isopropanol como estructurantes en diversas proporciones, obteniéndose en todos los experimentos TiO2 en fase anatasa. Para el segundo tipo de síntesis se empleó el tetracloruro de titanio en mezcla con sílica e isopropanol algunos de los TiO2 se obtuvieron como fase anatasa mientras que otros cristalizaron como una mezcla anatasa-rutilo en diferentes proporciones, dependiendo de las relaciones entre los precursores en la gel de síntesis. La caracterización de los materiales obtenidos se realizó por medio de DRX y UV-Vis para determinar la cristalinidad y propiedades ópticas de los materiales obtenidos

Mercado de Medicamentos, Regulación y Políticas Públicas

Este documento tiene el propósito de analizar el documento de Fedesarrollo: "Efectos económicos y sociales de la regulación sobre la industria farmacéutica colombiana: El caso de los estudios de bioequivalencia y biodisponibilidad de los secretos empresariales y las buenas prácticas de manufactura" Zuleta and Junca (2001), tanto en sus aspectos conceptuales y metodológicos, como de resultados. El estudio se centra en tres aspectos esenciales: la exigencia de estudios de biodisponibilidad y bioequivalencia (ByB) relacionados con la obtención-renovación de registros sanitarios por parte de la industria farmacéutica; el secreto empresarial relacionado con la calificación de la información que sustenta los registros, y la aplicación de las medidas relacionadas con las buenas prácticas de manufactura (BPM).Industria Famacéutica, medicamentos, patentes, marcas, normas, bioensayos, Colombia

Penetrating cardiac trauma: Analysis of 240 cases from a hospital in Bogota, Colombia

Background: Trauma characteristics and its management is influenced by socioeconomic context. Cardiac trauma constitutes a challenge for surgeons, and outcomes depend on multiple factors including initial care, characteristics of the wounds, and surgical management. Methods: This is a retrospective cross-sectional case series of patients with penetrating cardiac injuries (PCI) from January 1999 to October 2009 who underwent surgery in a trauma referral center in Bogotá, Colombia. Demographic variables, trauma characteristics, treatment, and outcomes were analyzed. Results: The study included 240 cases: 96.2% males, mean age of 27.8 years. Overall mortality was 14.6%: 11.7% from stab wounds and 41.2% from gunshot wounds. Upon admission, 44% had a normal hemodynamic status and 67% had cardiac tamponade. About 32% had Grade II injuries and 29% Grade IV injuries. In 85% of the cases, there were ventricular compromise and 55% of patients had associated lesions. In 150 cases, a pericardial window was performed. Highest mortality occurred in wounds to the right atrium. In tamponade patients, mortality was 20% being higher for gunshot wounds (54.5%) than for stab wounds (18%) (p = 0.0120). Conclusions: The study evidenced predominance of stab wounds. Based on characteristics of the trauma, patients, and survival rate, there is most likely a high pre-hospitalization mortality rate. The difference in mortality due to stab wounds and those produced by gunshots was more related to technical difficulties of the surgical repair than with the type of injury established by the Injury Grading Scale. Mortality was higher in patients with cardiac tamponade. Surgical management was satisfactory using pericardial window as the diagnostic method and sternotomy as the surgical approach. © 2017 The Author(s).Background: Trauma characteristics and its management is influenced by socioeconomic context.
