This paper presents the development and testing of an ontology of procedures for the "Government On-line" strategy of the Government of the Republic of Colombia. This ontology performs knowledge modeling of paperwork that performs a citizen to the Colombian State, which allows the establishment of a common language for information exchange and interoperability between the different entities of the state, taking advantage of the ability of the ontologies to declare homogeneous domain models by defining concepts, properties, and relations between them. Two agents are also presented: Citizen and Entity, which interact using this ontology by facilitating the search for information and data sharing. Finally the agents’ actions are exposed as web services and stress tests are carried out to the agent actions with JMeter. © Research India Publications. Source

Objective: To determine the frequency of intestinal parasites in children and soil from Turbaco- Colombia and associated risks factors. Methods: Analytical study in which 390 children between 2 and 12 years old from 10 neighborhoods of Turbaco were included, whose legal representatives gave informed consent. Three serial samples of feces and 10 soil samples were processed. Risk factors were determined through an interview. Physicochemical and structural characteristics of soils were also evaluated. Results: Parasites were found in 30.5 % of children. 162 parasites were observed; the most frequent protozoan was Endolimax nana (30.3 %) and in terms of helminthes, the most frequent was Ascaris lumbricoides (4.9 %). No statistical association between age or sex and intestinal parasites (p>0.05) or between risk factors and intestinal parasites (p>0.05) was found. Low frequencies of intestinal parasites were encountered in soil samples, being more common Entamoeba spp., Giardia spp., and Ascaris lumbricoides. Neighborhoods of Turbaco had sandy dry soil with low content of ions, low conductivity and low organic matter. Conclusion: This study showed a low frequency of intestinal parasites in feces and soils. Despite this, pathogenic parasites were found which can affect the health of the population. Besides this, a high percentage of intestinal parasites that are transmitted through feces were detected indicating fecal contamination and low level of hygiene. © 2016, Universidad Nacional de Colombia.

Since 1998, there are countless research studies about the diagnosis of Diabetes Mellitus, based on information from the data set PIDD - Pima Indian Diabetic Database by the National Institutes of Diabetes and Digestive and Kidney Diseases. PIDD is a standard for analysis and accuracy in the diabetes diagnosis, applied to different algorithms with a hit rate from 66% to 82.6%. This article presents the application of a training algorithm that can improve accuracy and interpretability of data, through a fuzzy classifier to determine, if the patient shows signs of the disease according to the criteria of the World Health Organization (WHO). © Research India Publications.

Objective: to identify the stage of skeletal maturation according to the chronological age of pediatric patients ranging from 8 to 12 years who attended the Dental Program at the Corporacion Universitaria Rafael Núñez. Methods: Cross-sectional descriptive study conducted from 2012 to 2013, in children from 8 to 12 years presenting digital cephalic lateral radiographs. C2, C3 and C4 vertebrae were identified; strokes of the vertebrae were performed with graphite pencil on tracing paper. Results: From a total of 100 pediatric patients studied, 49% (49) were male and 51% (51) female. The average age of both was 9.1 ± 1.02, 48% were in stage 1 (CMV1), 38% were in stage 2 (CMV2), and 14% were in stage 3 (CMV3). Conclusion: girls had earlier changes than boys. The cephalic lateral radiograph is a useful, economical, easy and reliable method to assess the degree of ossification, and it is statistically reliable and valid. © 2015, Universidad del Norte.
