Abstract: Disclosed is a technique for switching from a master node to a secondary node in a communication system. A method of a first communication node may comprise: adding the first communication node as a primary secondary cell (PSCell) to a second communication node through dual connectivity (DC); generating a first user plane path for smart dynamic switching (SDS) and a first instance for supporting the first user plane path according to a request from the second communication node; transmitting information on the first user plane path and the first instance to a terminal; receiving user data based on the first user plane path from the terminal as the first instance; and transmitting the user data to a core network using the first user plane path.

Abstract: An embodiment solid electrolyte includes a first compound and a second compound. The first compound is represented by a first chemical formula Li7-aPS6-a(X11-bX2b)a, wherein X1 and X2 are the same or different and each represents F, Cl, Br, or I, and wherein 0<a?2 and 0<b<1, and the second compound is represented by a second chemical formula Li7-cP1-2dMdS6-c-3d(X11-eX2e)c, wherein X1 and X2 are the same or different and each represents F, Cl, Br, or I, wherein M represents Ge, Si, Sn, or any combination thereof, and wherein 0<c?2, 0<d<0.5, and 0<e<1.

Abstract: The present invention relates to a disposable tray for a food steamer, comprising: a support that stands upright in a vessel while being supported, at the lower end portion thereof, by the vessel; and an upper plate that is horizontally formed on the upper portion of the support to have a predetermined area and has a plurality of through-holes formed therein. The support is bonded to the lower surface of the upper plate, or is separated from, or coupled to, the upper plate through a coupling part that is formed on the upper end of the support and is inserted into and coupled to a slit formed in the upper plate.

Abstract: A connection structure of a plasma display panel is provided that includes a first substrate having a plurality of panel-electrodes, a second substrate having a plurality of connecting-electrodes arranged to correspond to the panel-electrode, and a connection member located between the first substrate and the second substrate to directly connect the connecting-electrodes with the panel-electrodes upon compression.
