Sustainability is a topic that is at the center of current discussions in the political, economic, social, and environmental fields. For its analysis, an integral and multidisciplinary vision is needed. This work aims to assess the sustainability of agricultural systems in Paraguay through a comparison applying SAFA (Sustainability Assessment of Food and Agriculture Systems) indicators. The research focuses on 15 case studies on the territory of the Eastern Region of Paraguay divided into five classes of agricultural systems: agribusiness, conventional peasant family farming, agroecological peasant family farming, neo-rural farming, and indigenous agriculture. Data were collected through interviews with producers and key informants, direct observation, and scientific literature research in order to assess, through the SAFA Tool Software, the level of sustainability of each agricultural system as a whole and for each sustainability dimension (political, environmental, economic, and social dimension) in a comparative way. It has emerged that producers belonging to conventional peasant family farming, agroecological peasant family farming, neo-rural farming, and indigenous agriculture have achieved levels of sustainability that are similar to each other and very good in all four dimensions of sustainability. Meanwhile, agribusiness achieved moderate scores in the dimensions of governance and environmental integrity, and was good in the economic and social dimension.
Imaging approach to acute aortic syndrome Acute aortic syndromes include a spectrum of life-threatening aortic conditions. A review of the diagnostic aspects of the acute aortic syndrome was made, from the perspective of the imaging techniques available for this purpose. The advantages and disadvantages of each technique and its diagnostic performance were evaluated. Emphasis was placed on the relevance of clinical information as a fundamental tool for suspecting this syndrome and appropriately choosing the imaging technique. Our main objective is to provide information about the diagnosis of this condition, especially in the context of emergency services.
La cartelería publicitaria en sitios urbanos puede convertirse en un contaminante visual con efectos variados sobre el ambiente y las personas. En este estudio se describió el efecto ambiental percibido por parte de la población en las zonas con mayor dinámica de cartelería publicitaria. El estudio es cuali-cuantitativo, no experimental, transeccional y exploratorio-descriptivo. Para el estudio se definieron dos sitios de muestreo sobre intersecciones de avenidas principales de la capital que mostraron mayor cantidad de carteles habilitados en el periodo 2014-2016. En cada punto se
realizó observación y se incluyó la percepción de pobladores, transeúntes, informantes clave y calificados. Algunos de los .efectos ambientales negativos más mencionados fueron tala de árboles para la colocación de carteles y afectación de la imagen de la ciudad de Asunción como una ciudad sostenible. Se concluye que la presencia de cartelería publicitaria puede ocasionar daños ambientales en los entornos urbanos donde se encuentra inserta.
