Animation Plans for Before-and-After Satellite Images.

Before-and-after image pairs show how entities in a given region have evolved over a specific period of time. Satellite images are a major source of such data, that capture how natural phenomena or human activity impact a geographical area. These images are used both for data analysis and to illustrate the resulting findings to diverse audiences. The simple techniques used to display them, including juxtaposing, swapping and monolithic blending, often fail to convey the underlying phenomenon in a meaningful manner. We introduce Baia, a framework to create advanced animated transitions, called animation plans, between before-and-after images. Baia relies on a pixel-based transition model that gives authors much expressive power, while keeping animations for common types of changes easy to create thanks to predefined animation primitives. We describe our model, the associated animation editor, and report on two user studies. In the first study, advanced transitions enabled by Baia were compared to monolithic blending, and perceived as more realistic and better at focusing viewer's attention on a region of interest than the latter. The second study aimed at gathering feedback about the usability of Baia's animation editor.

Calidad de vida en pacientes con ictus. Un estudio fenomonológico / Quality of life in stroke patients. A phenomenological study

Objetivo Explorar la percepción de calidad de vida que tienen las personas afectadas por el primer episodio de ictus.MétodoEstudio cualitativo fenomenológico. La recogida de datos ha sido realizada por entrevistas semiestructuradas a pacientes que acudieron a consulta de Neurología del Hospital Ramón y Cajal desde febrero a octubre del 2008. Los 20 participantes se ajustaron al criterio de inclusión de 10–14 meses de evolución y de exclusión de no tener alteradas las funciones psíquicas superiores, ni las de comunicación. El muestreo empleado ha sido por propósito, seleccionados según los perfiles previamente determinados.ResultadosEl ictus es interpretado como una situación adversa puntual en su salud y no como una enfermedad. La adaptación al entorno supone enfrentarse a las secuelas, lo que influirá directamente en la manera de percibir, construir y organizar sus redes sociales: red social demandada de cuidado—formal e informal— y red social afectada por el cambio—ámbito laboral y amigos—, utilizando diferentes estrategias de afrontamiento, donde hay avances y retrocesos.ConclusionesLa percepción de calidad de vida es un concepto subjetivo, flexible y particular al sujeto que se ajusta a cada momento del proceso de recuperación y cuya base se centra en cubrir las necesidades demandadas (biopsicosociales) en cada momento de experimentación. Sobrevivir a un ictus es: superar el impacto y recuperar, en la medida de lo posible, las secuelas derivadas; cambiar el estilo de vida individual y compartida; reestructurarse en la nueva identidad y reubicarse en el contexto social(AU)
