BACKGROUND The detection of sub-clinical breast lesions has increased with screening mammography. Biopsy techniques can offer precision and agility in its execution, as well as patient comfort. This trial compares radioguided occult lesion localization (ROLL) and wire-guided localization (WL) of breast lesions. We investigate if a procedure at the(More)
This paper focuses on the support provided by NCL (Nested Context Language) to relate objects with imperative code content and declarative hypermedia-objects (objects with declarative code content specifying hypermedia documents). NCL is the declarative language of the Brazilian Terrestrial Digital TV System (SBTVD) supported by its middleware called Ginga.(More)
Hypermedia content workflows involve many environments and actors, from the content producer to the service operator, from the editing studio to the service head-end. They all have different needs on hypermedia content creation and editing. Nowadays, even viewers are demanding tools to enrich content. But currently a single authoring tool cannot fulfill(More)

The incidence of CM in the southern region of Brazil, particularly in the western region of Santa Catarina, is possibly higher than estimated. In this study, the clinical and epidemiological profile of patients with CM treated in the western region of Santa Catarina was(More)
Despite of the establishment of digital television services, audience measurement and other media analysis still rely on obsolete and usually expensive techniques that date back to the analog era. Moreover, the introduction of interactive services into TV terminal devices is not adequately considered in such market researches. The analysis of both viewer's(More)
