  • Patent number: 10472485
    Abstract: The present invention relates to a composite powder of scoria powder and a porous polymer. More particularly, the present invention relates to a composite powder (scoria sphere) in which the surface and the inside of a porous polymer are uniformly impregnated with scoria powder particles prepared by spraying in one-step a dispersion in which scoria powder is dispersed in a solution in which a polymer is dissolved; a cosmetic composition containing the same; and a process for producing the same. When the scoria impregnated powder, of the present invention, in which the porous polymer is uniformly impregnated with the scoria powder particles, is formulated as a cosmetic composition, the porous polymer supplements the sebum absorption performance of the scoria miniaturized in a micro size, and thus the sebum absorption power is greatly improved.

  • Patent number: 10313869
    Abstract: A method and apparatus for supporting Non-Access Stratum (NAS) communication between a User Equipment (UE) and a Mobility Management Entity (MME) efficiently by addressing the signaling problems occurring between the UE and the MME in a situation where it is necessary for a network node to identify the UE and acquire UE information, if there is any, from another network node to which the UE has been attached, are provided. The method for communication between the UE and network based on the NAS protocol messages and operations is implemented with the involvement a UE, an MME, and an old MME or an old Serving General Packet Radio Service (GPRS) Support Node (SGSN) to which the UE has been attached before so as to facilitate discovering a best node using the UE information acquired from the old MME or old SGSN during the communication between the UE and the network, resulting in a reduction of a communication delay between the UE and network and an improvement of communication efficiency.
