Abstract: Provided is a duct docking device for a ventilation seat of a vehicle. The duct docking device enables air to be easily blown to a seatback and a seat cushion with a passenger in a seat using only one blower by enabling a seatback duct mounted at the seatback and a seat cushion duct mounted at the seat cushion to be hermetically docked through a connector duct, etc. at an unfolded position of the seatback in which a passenger can sit, and by enabling the seatback duct mounted at the seatback and the seat cushion duct mounted at the seat cushion to be separated from each other at a folded position of the seatback in consideration of that there is no passenger in the seat.

Abstract: The present disclosure discloses a gate-all-around field effect transistor which not only can suppress the occurrence of punch through in the lower end of the substrate and direct leakage of current from the source region/drain region into the lower ends of the channels, but also can facilitate heat release of the substrate by forming trench inner spacers (TIS) and thus preventing source region/drain region impurities from diffusing into the substrate, and a method for manufacturing the same.

Abstract: Provided is a method for cell isolation and morphological analysis. The method includes: providing a substrate with one or more wells; inserting cell isolation devices, each of which has one side patterned with one or more microwells, into the wells; introducing a liquid medium including cells into the wells; allowing the microwells of the cell isolation devices to come into contact with the inner surfaces of the wells such that some of the cells are isolated and trapped at the level of individual cells in the microwells; and observing the morphological changes of the isolated cells.

Abstract: The present disclosure suggests a method of manufacturing flake aluminum oxide using a microwave including: performing a pre-treatment on a starting material by grinding the starting material such as alumina hydrate, aluminum salt or the like and classifying particles with an appropriate size; manufacturing transition alumina by performing a heat treatment by means of heating the pre-treated starting material; mixing the transition alumina with molten salt and an additive and then dispersing and grinding the mixed compounds; melting and synthesizing flake aluminum oxide by heating the dispersed and grinded mixture with a microwave as a heating source; separating the molten salt and the additive from the synthesized aluminum oxide; and performing a post-treatment on the flake aluminum oxide by removing a foreign substance such as an additive residue stuck to a surface of a crystal particle of the separated flake aluminum oxide.
