This paper describes a computer­assisted language learning (CALL) in a ubiquitous computing environment. The environment, called TANGO (Tag Added learNinG Objects) system, detects the objects around the learner using RFID (Radio Frequency Identification) tags, and provides the learner the right information for language learning.

The clinical presentation, initial laboratory and renal biopsy findings, and course of focal segmental glomerulosclerosis (FSGS) were studied retrospectively in 57 children in order to compare findings in those with and without nephrotic syndrome and to establish factors of prognostic significance. All patients had proteinuria. Eleven patients were(More)
An electron microscopic study of the nonsclerotic glomeruli or nonsclerosed segments of affected glomeruli was made in 34 children with nephrotic syndrome and focal segmental glomerulosclerosis (FSGS) and in 34 children with minimal-change nephrotic syndrome. Particular attention was paid to alterations of glomerular epithelium. The most striking glomerular(More)
Twenty-seven children with focal segmental glomerulosclerosis (FSGS) were studied for clinical and pathological manifestations in order to determine whether the location of the sclerotic lesions bears prognostic implications. There were 11 children with peripheral FSGS and 16 with hilar FSGS. During a mean follow-up period of 6 years, 10 of the 16 with(More)
