The access card processing method may, if a produced access card is issued by a partner terminal and then transferred/retransferred, or a user terminal holding the access card returns the access card, or the access card is retrieved by the partner terminal, provide a message related to the transfer/return/retrieval so as to enable a situation regarding the transfer/return/retrieval to be recognized.

Abstract: An access card providing method, an access card checking method, and an apparatus for performing the methods are disclosed. An access card providing method may comprise producing a virtual access card by a partner terminal desiring to produce the access card, which allows entering of an online or offline area of a partner, wherein the access card is provided through an application of a user terminal. An access card checking method may comprise, when a user terminal having issued an access card to an offline area of a partner recognizes identification information, identifying whether an access card corresponding to the identification information has been issued so as to check the access card.

Abstract: The present invention relates to a novel lactobacillus fermentum ATG-V5 strain or a composition for enhancing immunity, comprising same. The Lactobacillus fermentum ATG-V5 strain of the present invention has no cytotoxicity, and has the effect of enhancing immunity, such as increasing the amounts of nitric oxide (NO), interleukin 6 (IL-6) and tumor necrosis factor (TNF) secretion and phagocytosis of macrophages, reducing the amount of interleukin 1? (IL-1?) secretion of macrophages, increasing the cell viability of splenocytes, and increasing the amount of antibodies and cytokines secretion in the blood, and thus the strain can be effectively used as a material for a composition and a health functional food for enhancing immunity, and the composition and health functional food can be effectively used in enhancing individual immune activity. In addition, a health functional food comprising the food composition is also effective in enhancing individual immune activity.

Abstract: Provided are a method for manufacturing a high yield and high performance mesophase pitch and a high yield and high performance mesophase pitch manufactured therefrom by hydrogenating, mesophase formation, thin film evaporation, solvent-extracting, filtering and then drying to obtain only mesogen components in flow-domained mesophase pitch and then mixing the mesogen components with an isotropic pitch as a solvent component. Further, the high yield mesophase pitch of the present disclosure exhibits high spinnability while maintaining whole anisotropy and exhibits a much higher production yield than existing mesophase pitches.
