Abstract: The present invention relates to a pidolate salt and malate salt of a compound represented by a formula 1 with an excellent liquid-phase stability, solid-phase stability, water solubility, precipitation stability and hygroscopicity all together as a compound for preventing and treating diseases mediated by an acid pump antagonistic activity, as well as a method for preparing the same.

Abstract: The present disclosure relates to an isolated anti-FcRN antibody, which is an antibody binding to FcRN (stands for neonatal Fc receptor, also called FcRP, FcRB or Brambell receptor) that is a receptor with a high affinity for IgG or a fragment thereof, a method of preparing thereof, a composition for treating autoimmune disease, which comprises the antibody, and a method of treating and diagnosing autoimmunre diseases using the antibody. The FcRn-specific antibody according to the present disclosure binds to FcRn non-competitively with IgG to reduce serum pathogenic auto-antibody levels, and thus can be used for the treatment of autoimmune diseases.

Abstract: A user key management method for a broadcast encryption includes assigning node path identifiers (IDs) to nodes arranged in sequence; assigning random seed value keys to the nodes according to the node path IDs; generating key values by repeatedly applying a hash function to the assigned random seed value keys; and assigning the generated key values to the nodes in sequence. Accordingly, it is possible to reduce the transmission overhead that is most important matter in the broadcast encryption to less than the number of the revoked users. Further, there is an advantage that the transmission overhead of the exemplary embodiments of the present invention is remarkably reduced compared with the Subset Difference method.
