In contrast to onetoone visits, SMAS provide a longer appointment timeframe as well as the opportunity for patients to have improved access to their physicians and meanwhile pick up additional information and support from peers.s office and the queue of patients outside the door seems to be pressing rather too hard.

A.t draw the maps their teacher wanted on their tiny boards, so Pillans put several slates together to create a large board. Problem solved! From there, the idea spread quickly as teachers could finally show a concept to the whole class at one time. By 1815, the massive writing spaces were mon enough to earn their own name: blackboard.s up with the name? Originally, blackboards were really black. Before wallsized blackboards existed, late 18thcentury students used their own mini boards made of slate (石板) or painted wood, according to Concordia University, Those first boards were, in fact, black, and they paved the way for the larger ones. When you think back to the blackboard from your school days, what color is it?
