Martha Marín C.
Nómadas , 1994,
Abstract: Sobre una de las películas preferidas por el público receptor de cine de Bogotá, el ensayo que sigue es un ejemplo del análisis semiotextual que intenta integrar los componentes cinematográficos, de representación, las estructuras narrativas y de comunicación presentes en el film. Su propósito es descubrir una matriz de lectura como universo o eje de sentido -en este caso denominada apocalíptica/tecnológica- y acercarse al mundo simbólico-imaginario allí objetivado, para realizar una caracterización del espectador “previsto por la película”.

Abstract: introduction. faecal contamination in wastewater and drinking water is linked to the dissemination of water related diseases. the bacteria, virus and parasites present in drinking water are responsible for substantial morbidity and mortality, especially among infants. giardia spp. and cryptosporidium spp. were the organisms selected as parasite contamination indicators. their presence serves as a useful tool for evaluating water quality and determining sanitary risk. at present, in colombia, concentration and occurrence of these parasites is unknown and an immediate assessment was considered necessary. objective. protozoan presence was determined in five sampling stations in the bogotá river upper basin and in two drinking water plants near the same area. materials and methods. the techniques applied for counting encysted forms consisted of inorganic flocculation for wastewater or filtration for drinking water. fluorogenic vital dyes tested for viability. results. the presence of cryptosporidium spp. was confirmed in two of the sampled stations and at two of the drinking water plants. giardia spp. was found at two of the drinking water plants but not at the sampled stations. viable cysts were found for cryptosporidium spp. in one of the samples from the bogotá river, but only inviable exemplars were obtained from the drinking water plants. conclusions. the results revealed protozoan presence in drinking and residual water implying the presence of a potential sanitary hazard.

Nómadas , 1994,
Abstract: Este artículo se origina en el primer módulo de una línea de investigación pensada para avanzar en los estudios sobre comunicación/cultura. El proyecto intenta acercarse a la desconstrucción de objetos culturales (el cine en este caso) con una mirada conceptual nueva y metodologías plurales, adoptando como horizonte de pensamiento lo simbólico-imaginario, instancia crucial del problema cultural. Aunque los resultados y el análisis de este primer objeto no lleguen a conclusiones totalmente acabadas, el lector atento encontrará un universo sugerente de resemantizaciones y formas innovadoras de senti-pensar la significación.

Abstract: Se analizaron las muertes registradas como homicidio en México de 1979-1992. El estudio se basó en fuente secundaria, siendo las variables analizadas: a o, edad, sexo y causa externa de traumatismos y envenenamientos según CIE IX Rev.(E960-E969). Se utilizó un modelo de regresión Poisson para las causas más frecuentes, obteniendo riesgos relativos según edad y sexo. El grupo de referencia fue el de 10-14 a os y el sexo femenino. Se registraron 198,485 muertes por Homicidio, con un promedio anual de 14,177 y diario de 39. La principal causa fue ataque con arma de fuego y explosivos(56%). El riesgo relativo más alto fue para el grupo de 35-39 a os, con RR 15,4 IC(95%) 14,9-16,0, en comparación al de referencia. El sexo masculino presentó un riesgo relativo 10,1 veces mayor que el femenino, ajustado por edad IC10.0-10.3. Los resultados llaman la atención sobre la necesidad de profundizar y analizar el problema de los homicidios bajo una perspectiva multidisciplinaria.

Abstract: objective: this research had two objectives: (1) to determine the prevalence of iron-deficiency anemia and describe iron consumption in the diet of schoolchildren and adolescents enrolled in public and private schools of the urban area of the city of medellín, colombia, in the 1999-2000 school year and (2) to explore the associations that age group, sex, socioeconomic class, and intestinal parasitism show with iron-deficiency anemia and iron deficiency. methods: a cross-sectional study was carried out among 960 students from 6 to 18 years old who were selected by simple random sampling after stratified multistage sampling and clustering in public and private schools in districts of medellín. body iron content was evaluated by determining ferritin and hemoglobin levels, average corpuscular volume, and amplitude of the erythrocyte distribution; the presence of intestinal parasites was evaluated through stool analysis; nutritional status was evaluated by means of anthropometric measurements; and consumption of iron and vitamin c was evaluated using a semiquantitative questionnaire on food intake. in order to define the cases of iron-deficiency anemia and of iron deficiency we used the standard definitions of the world health organization, based on ferritin and hemoglobin values. we used nonparametric tests, with a significance level of 0.05, to examine the associations between age group, sex, socioeconomic class, and the presence of intestinal parasites on the one hand and the presence of anemia on the other hand. results: the prevalence of iron deficiency was 4.9%, and the prevalence of iron-deficiency anemia was 0.6%. the prevalence of both was higher among adolescent women (p < 0.05) than in the rest of the sample studied. no significant association was found between the presence of intestinal parasites and the presence of anemia. the average daily consumption of iron (± standard deviation) was 5.5 mg (± 2.3 mg) (32% ± 15% of the recommended dietary intake for the s

Abstract: plasmodiumspecies infecting man are the following: p.vivax, p. malariae, p. ovale and p. falciparum. in mozambique, like the biggest area from the so called subsaharian africa,the resistent-chloroquine p. falciparum is the predominating specie in this area. the p. falciparum infection is potentially fatal, with a trend to show as a febrile condition with no localized or specific signs. in more severe cases, however, it may be presented in association with different clinical syndromes which represent serious therapeutic challenges. it is not unknown that malaria or paludism may be associated with the nephrotic syndrome, and many explanations have been given on this pathogenic relatioship. in a sixth month's period in mozambique we had the chance to test three severe cases of falciparum malaria associated with a nephrotic syndrome. spreading the practical experience and theoretic considerations on one of these cases is the aim of this work.
