Rethinking functional limitation pathways.

Functional limitation has received considerable attention in gerontology and geriatrics. Much of this work has focused on single-wave transitions devoid of context rather than on the pattern of transitions over time that constitute trajectories. This Forum article suggests that it is time for a different way of looking at functional limitation pathways. It focuses on trajectories. Responses to ...

the effect of functional/notional approach on the proficiency level of efl learners and its evaluation through functional test

in fact, this study focused on the following questions: 1. is there any difference between the effect of functional/notional approach and the structural approaches to language teaching on the proficiency test of efl learners? 2. can a rather innovative language test referred to as "functional test" ge devised so so to measure the proficiency test of efl learners, and thus be as much reliable an...

あらまし 近年,サーバへの不正アクセスが問題となっている.問題の解決にあたり属性ベース暗号が 提案されている.しかし属性ベース暗号は動的な属性変化に対応できない.そこで,ユーザ属性鍵の失効 機能を備えた方式が求められる.既存研究として,更新鍵が必要だが Encryptorに失効者情報を意識さ せずに済む Indirectな失効方式や,更新鍵は不要だが Encryptorが失効者情報を暗号文に規定しなくて はならない Directな失効方式が提案されている.一方,関数型暗号をベースとした代理人再暗号化によ る失効方式も提案されている.この方式は条件式の自由度は高いが,鍵発行機関が単一の方式のみ提案 されている.本研究では,Indirect/Directの性質を同時に実現したパッチによる失効機能を有する,複 数の鍵発行機関が存在可能な関数型暗号を提案する.また,Indirectの長所と引...
