ABSTRACT The objective of the study was to classify 80,246 hectares on the right bank of the Paraguay river belonging to the Chaco Humid region. On two occasions, in 2000 and 2016, was interpreted the vegetal cover and the land use of this area. In the year 2000, through the analysis of the satellite image interpretation on a scale of 1:50,000 were delimited and differentiated six landscapes units. Sixteen years later, it was analyzed the possible changes occurring of the pertinent surfaces of the six landscape units. For the year 2016, the area occupied by non-flooded humid Chaco forest was 31,494 ha, flooded humid Chaco forest 27,986 ha, palm area - karanda´y 9,190 ha, shrub vegetation of flooded areas 6,058 ha, anthropic area 4,210 ha and water reservoirs 1,308 ha. From the total area, 44 %of the was identified as permanently flooded,16% temporarily flooded and the non-flooded area corresponded to 40%. It was verified that, over the course of 16 years, the area occupied by human settlements has an increase of more than three thousand percent, while the other defined landscape units did not show consistent changes.

RESUMEN El objetivo del estudio fue clasificar 80.246 hectáreas de la margen derecha del río Paraguay pertenecientes a la ecorregión Chaco Húmedo. En dos ocasiones, en 2000 y 2016 se interpretó la cobertura vegetal y el uso del suelo de esa área. En el año 2000 a través del análisis de una carta imagen, en escala 1:50.000, por la teledetección fueron delimitadas y diferenciadas seis tipologías de paisajes. Se analizó 16 años más tarde, los posibles cambios ocurridos de las pertinentes superficies de las seis tipologías de paisaje. Para el año 2016, la superficie ocupada por el bosque húmedo chaqueño no inundable fue de 31.494 ha, bosque húmedo chaqueño inundable 27.986 ha, karanda´y 9.190 ha, vegetación arbustiva de áreas inundadas 6.058 ha, área ocupada por asentamientos humanos 4.210 ha y los cuerpos de agua 1.308 ha. De ese total, 44% del área se identificó como permanentemente inundada, 16% temporalmente inundada y el área no inundable correspondió a 40%. Se verificó que, en el transcurso de 16 años, la superficie ocupada por los asentamientos humanos tuvo un aumento de más de tres mil porcientos, mientras que las demás tipologías de paisaje definidas no sufrieron consistentes alteraciones.

Abstract Introduction Brazilian Telehealth Program was instituted by the Ministry of Health in 2007. Its initial structure was composed by nine telehealth centers administered by public higher education institutions. No standards, processes, applications or quality indicators had been defined since its creation. All this, combined with the decentralization of the centers, led each one of them to develop their own system, with different programming languages and architectures. The lack of regulation and integration of the information with the Ministry of Health made it difficult to evaluate the program. In this context, this paper describes the specification, implementation and validation of an architecture, entitled SMART, to integrate the various telehealth platforms developed by the centers. Such architecture aims to standardize information so that the Ministry of Health can monitor and evaluate the results of Telehealth actions. Methods SMART’s architecture consists of four main components: a web tool for data manipulation; a web service to receive the center’s production data; a component responsible for converting the received data into decision support data; and a component that collects data from external sources to compose the data warehouse. Results The architecture was validated with performance tests, which were executed under extreme workloads. The results of the experiments were summarized in order to attest SMART’s effectiveness. Conclusion The analysis of the results obtained on real data shows that the project’s performance remained stable under the workloads and its high quality was proven due to the absence of errors during the experiments.

Resumen El área del Eco-Museo del Cerrado cubriendo una superficie de 8066 km2 fue interpretada por imágenes de satélite, en dos ocasiones, en los años 2002 y 2017. Se ubica en la región central del Brasil, específicamente en siete distritos municipales (municipios) del estado de Goiás. Fueron clasificadas tres unidades interpretativas: el área cubierta por bosques, sabanas y asentamientos humanos. Esas unidades fueron clasificadas por distrito municipal y por cuenca hidrográfica. El mayor cambio de superficie se observó en los asentamientos humanos. En 2002, 58 % del área total, los asentamientos humanos estaban ocupados por pequeñas poblaciones, con énfasis en la parte este del eco-museo. En 2017 se verificó correspondientemente un aumento del 9,2 %. En contra posición, los bosques y las sabanas disminuyeron para 16,5 y 16,2 % respectivamente.

Abstract The area of the Savannah Eco-Museum covers 8066 km2. The area in two occasions at the years 2002 and 2017 was interpreted through satellite images. The area is located in central Brazil region, specific in seven counties of the state of Goiás. It was classified three interpretative units: forest, savannah and human settlements covers areas. These units were classified into the counties and watersheds. The most surface change was observed at the human settlements. In 2002, 58 % of the total area was occupied with the human’s settlements, with emphasis in the west side of the eco-museum. In 2017, it was verified an increase of 9.2 %. As opposed the forest and savannah areas shows a decrease from 16.5 and 16.2 % respectively.

A área do Projeto Ecomuseu do Cerrado cobre uma superfície de 8.066 km², localizados no Estado de Goiás, próximo à cidade de Brasília. Sete municípios integram a área do ecomuseu. Através da interpretação de duas imagens do satélite Landsat5, foi classificado o uso atual do solo da área do ecomuseu em matas (19%), cerrado (23%) e porção antropizada (58%). Sobrepondo diversos mapas existentes da região, foi possível identificar as regiões prioritárias por município, para a correspondente conservação da diversidade biológica. O total dessas áreas prioritárias cobre uma superfície de 4.444 km², correspondendo a 55% da superfície do ecomuseu.

The area of the Savanna Ecomuseum Project covers 8.066 km², in the State of Goiás, close to the city of Brasilia. Seven counties constitute its total area. Through the interpretation of two Landsat5 TM data, the ecomuseum area has been classified as forests (19%), savanna (23%), and anthropic area (58%). By overlaying several maps of the region, it was possible to identify priority areas per county, for conservation of biological diversity. The total area of these priority sites covers a surface of 4.444 km², corresponding to 55% of the ecomuseum total area.
