Abstract: The objective of this work was to evaluate the influence of fresh water shrimp Macrobrachium amazonicum (Heller, 1862) in performance of Nile tilapia (Oreochromis niloticus) cultivated in polyculture system and feeding with ration pelleted and mashed. The work was realized in Centro de Pesquisa em Aqüicultura Ambiental-CPAA/IAP – Toledo/PR during 37 days. Were utilized like experimental unit 16 ponds excavated, covered with concrete but with bottom of soil with dimension the 4 x 3 m and useful volume the 3,5 m3. Were utilized 30 tilapias e 150 shrimps for experimental unit distributed at an entirely randomized design with 4 treatments and 4 replications, where TF: tilapia feeding with ration mashed; TCF: tilapia and shrimp feeding with ration mashed; TP: tilapia feeding with ration pelleted; TCP: tilapia and shrimp feeding with ration pelleted. The density used were the 2,6 fishes/m2 with medium initial weight the 5,58 ± 0,10 g and initial length the 5,56 cm, and the density of shrimp was the 13 shrimps/m2 with initial length the 1,04 cm. The temperature was gauged daily, while the variables dissolved oxygen, pH and electrical conductivity, weekly. The quantity of ration supplied was the 10% of total biomass of fishes, with feed frequency the 4 times a day, being corrected weekly in function of the biometry. During the experimental period the medium values of temperature, dissolved oxygen, pH and electrical conductivity of the ponds water were 23,42 ± 0,83oC, 5,32 ± 0,52 mg/L, 7,02 ± 0,39, e 100,96 ± 1,81 μS/ cm respectively. Won′t registering any influence of shrimp during the cultivation and the ration pelleted provide the better conversion alimentary and performance of tilapias.

Abstract: Background Colombia has a highly segmented and fragmented national health system that contributes to inequitable health outcomes. In 2004 the district government of Bogota initiated a Primary Health Care (PHC) strategy to improve health care access and population health status. This study aims to analyse the contribution of the PHC strategy to the improvement of health outcomes controlling for socioeconomic variables. Methods A longitudinal ecological analysis using data from secondary sources was carried out. The analysis used data from 2003 and 2007 (one year before and 3 years after the PHC implementation). A Primary Health Care Index (PHCI) of coverage intensity was constructed. According to the PHCI, localities were classified into two groups: high and low coverage. A multivariate analysis using a Poisson regression model for each year separately and a Panel Poisson regression model to assess changes between the groups over the years was developed. Dependent variables were infant mortality rate, under-5 mortality rate, infant mortality rate due to acute diarrheal disease and pneumonia, prevalence of acute malnutrition, vaccination coverage for diphtheria, pertussis, tetanus (DPT) and prevalence of exclusive breastfeeding. The independent variable was the PHCI. Control variables were sewerage coverage, health system insurance coverage and quality of life index. Results The high PHCI localities as compared with the low PHCI localities showed significant risk reductions of under-5 mortality (13.8%) and infant mortality due to pneumonia (37.5%) between 2003 and 2007. The probability of being vaccinated for DPT also showed a significant increase of 4.9%. The risk of infant mortality and of acute malnutrition in children under-5 years was lesser in the high coverage group than in the low one; however relative changes were not statistically significant. Conclusions Despite the adverse contextual conditions and the limitations imposed by the Colombian health system itself, Bogota’s initiative of a PHC strategy has successfully contributed to the improvement of some health outcomes.

Abstract: Patients who attended the three major HIV/AIDS healthcare centres in Bogota were prospectively studied over a six month period. A total of 286 patients were enrolled, 20% of them were hospitalized at some point during the study. Sixty four percent (64%) were classified as stage C, 25% as stage B, and 11% as stage A (CDC staging system, 1993). A total of 1,622 clinical samples (mostly paired samples of blood, sputum, stool, and urine) were processed for acid-fast bacilli (AFB) stain and culture.Overall 43 of 1,622 cultures (2.6%) were positive for mycobacteria. Twenty-two sputum samples were positive. Four patients were diagnosed with M. tuberculosis (1.4%). All isolates of M. tuberculosis were sensitive to common anti-tuberculous drugs. M. avium was isolated in thirteen patients (4.5%), but only in three of them the cultures originated from blood. The other isolates were obtained from stool, urine or sputum samples. In three cases, direct AFB smears of blood were positive. Two patients presented simultaneously with M. tuberculosis and M. avium.Non-tuberculous Mycobacterium infections are frequent in HIV infected patients in Bogota. The diagnostic sensitivity for infection with tuberculous and non-tuberculous mycobacteria can be increased when diverse body fluids are processed from each patient.Mycobacterium infections are frequent opportunistic pathogens associated with the acquired immunodeficiency syndrome (AIDS). Its relative virulence and potential for person-to-person transmission distinguishes Mycobacterium tuberculosis. Persons infected with the human immunodeficiency virus (HIV) are particularly susceptible to tuberculosis, either by the reactivation of latent infection or by a primary infection with rapid progression to active disease [1-4]. The annual incidence rate of tuberculosis in Colombia during 1998 was 19.6 per 100,000 persons [5], but rates 1,000-fold higher have been reported in some HIV-seropositive populations [6-14]. In addition, disseminated i

Abstract: En este trabajo presentamos los resultados de un estudio elaborado en Bogotá con 210 estudiantes universitarios de 5 instituciones con diferentes características sociodemográficas, con el fin de establecer las normas categoriales léxicas. Se utilizaron las 56 categorías léxico-semánticas usadas en el clásico estudio de Battig y Motague (1969) y se recogieron más de 7800 palabras que fueron organizadas por rango y moda. En la revisión bibliográfica realizada no se encontraron trabajos de esta naturaleza para el espa ol colombiano (o latinoamericano), y se espera que sus resultados sean usados en protocolos para el campo de la terapia del lenguaje y los estudios psicolingüísticos. Los datos recogidos fueron comparados con uno de los estudios de norma categorial realizados para el espa ol ibérico. In this article, we present the results of a study carried out in Bogotá, Colombia with 210 university students from five different universities pertaining to diverse socio-demographic groups. The objective of the study was to establish the lexical category norms. 56 lexical-semantic categories used by Battig and Montague (1969) in their classic study were employed. More than 7800 words were collected and organized by range and mode. There are no other studies on this subject for Colombian or Latin American Spanish. We hope that the results presented here will be used both in psycholinguistic and language therapy studies. The collected data were compared to one of the category norm studies made for European Spanish.

Abstract: A la luz del “Plan estratégico Colombia libre de tuberculosis 2006-2015”, se identificaron factores relevantes de tipo demográficos, ambientales y sociales; que inciden sobre las condiciones de transmisión de la tuberculosis. Los datos obtenidos del Sistema de Vigilancia de Salud Pública (SIVIGILA) de la ciudad de Bogotá, se analizaron mediante la construcción de tablas de contingencia y de la asociación de las variables cualitativas mediante la prueba chi-cuadrado; todo ello con el fin de definir un diagnóstico temprano de la tuberculosis y el inicio oportuno del tratamiento, debido a que ésta es una de las enfermedades más infecciosas en el mundo y ha resurgido especialmente en los países en vías de desarrollo. Al ser Bogotá la ciudad en Colombia que recibe el mayor número de habitantes por condiciones de desplazamiento, búsqueda de oportunidades de trabajo y mejores condiciones de vida, entre otros; se hace importante y prioritaria la atención de dicha enfermedad.AbstractIn the light of the "Strategic Plan Colombia free of Tuberculosis 2006-2015”, relevant factors were identified, such as demographic, environmental and social factors, that affect the conditions of transmission of tuberculosis. The data obtained from the Public Health Surveillance System (SIVIGILA) of Bogota city, were analyzed by the construction of contingency tables and the association of qualitative variables, using the chi-square test; in order to define an early diagnosis of tuberculosis and a timely initiation of the treatment, since this is one of the most infectious diseases in the world and has emerged, especially, in developing countries. The attention of this disease must be a high priority for Bogota city in Colombia, taking into account that it receives the greatest number of people per shift conditions, search of job opportunities and better living conditions, among others.

Abstract: At present there are two systems of vegetable production in the Bogota Plateau, the conventional production systems (CPS) and the organic production systems (OPS). Soil samples were collected from both production systems. Each soil sample was performed and analyses of fertility based on data mining of nutrients were diagnosed with various aspects of the fertility of the soil chemistry. These were compared them with the standards of fertility and to supply tools to increase the productivity organic production system. The two systems of vegetables productions present pH adapted that fluctuant between 5.5 and 6.6. In the OPS presented deficient contents of phosphorus in the 92% of the soil samples, objected to CPS where it prevailed the deficiency in 73% of the soil samples. In the OPS presented deficient contents of sulphur in the 81% of the soil samples, contrasted with the 19% of CPS. The two systems of vegetables productions present deficient contents of manganese, reflecting the low contribution of this element in the plan nutrition, since the zone is deficient the contents natural.

Abstract: An analysis regarding the quality of higher education programmes in Colombia is presented by comparing students’ scores from a given institution on the ECAES 2009 test to students’ performance throughout the country. The analysis uses the value-added concept as applied to the academic world, this being obtained by using a regression model to ascertain the difference between the students’ scores from a given faculty programme and the corresponding scores for students throughout Colombia; the higher education admission test was used to control initial results with results achieved by the same individuals on this test., A case study was proposed to illustrate the methodology by considering the Faculty of Engineering programmes at the Universidad Nacional in Bogota. Two different approaches were followed; the first used the generated function between SABER 11 and ECAES test scores and the second added institutional results by using the mean of the scores. The aforementioned Faculty of Engineering ratifies its relevance and importance as all its programmes come within the greater academic value-added area. Se propone un análisis sobre la calidad de los programas de educación superior de Colombia, comparando los puntajes obtenidos por los estudiantes de una institución en la prueba Ecaes del a o 2009, frente a los desempe os de los demás estudiantes del país. El análisis emplea el concepto de valor académico agregado, que se evalúa en función de la diferencia resultante entre el puntaje obtenido por los estudiantes de un determinado programa y el respectivo puntaje hallado por regresión para los demás estudiantes del país, controlando la condición inicial mediante el resultado alcanzado por los mismos individuos en la prueba de ingreso a la educación superior. Para ilustrar la metodología se toman los programas de la Facultad de Ingeniería de la Universidad Nacional en Bogotá como caso de estudio, y se presentan dos caminos: primero, siguiendo la función generada entre los puntajes de las pruebas Saber 11 y Ecaes, en el ámbito del estudiante; y segundo, haciendo una síntesis por programa con los promedios de puntajes, en el ámbito de la institución. La Facultad de Ingeniería mencionada confirma su relevancia y trascendencia, porque todos sus programas se localizan en la zona de mayor valor académico agregado.

Abstract: Around the world, healthcare organizations have had to accommodate tonational and international regulations governing work and health. This process has been accompanied by the introduction of knowledge and practices coming from social and administrative sciences. In this encounter between the liberal reforms and the particular ways of managing the workforce, the circulating meanings play an important role because, to a large extent, the agendas, programs and interventions geared to towards workforce management depend on these circulating meanings to succeed. In this paper, meanings about work, worker, organization, human resources management and hiring that are currently circulating in a human resources department of a university hospital in Bogotá, Colombia, are presented. The qualitative design used in this paper aimed to collect the circulating meanings as wellas their emotional correlative elements.
