Abstract: Proposed are pharmaceutical and food compositions for alleviating and treating inflammatory diseases and allergic diseases, the compositions including propolis and Sorbus commixta as active ingredients. Preparation methods of the compositions are also proposed. The compositions are prepared by extracting a propolis ethanolic extract from a propolis powder using an aqueous ethanol solution through extraction and filtration, extracting a Sorbus commixta ethanolic extract from a Sorbus commixta powder using an aqueous ethanol solution through extraction and filtration, and mixing the propolis ethanolic extract and the Sorbus commixta ethanolic extract. Since propolis and Sorbus commixta are contained in the pharmaceutical and food compositions, the pharmaceutical and food compositions exhibit excellent anti-inflammatory and anti-allergic effects.

Abstract: Disclosed is a method and system for providing a game service, acquiring information about a user from a server offering a social network service and using the acquired user information, in a game environment managing an entity group including one or more entities, in which the entity group is formed by receiving user information of a user, who is accessing the terminal, from a third party server and creating an acquaintance group of the user based on the user information, receiving a selection of the acquaintance group, and matching a record, which corresponds to the selected acquaintance, with entity included in the entity group. The game service is provided to a terminal of the user with reference to the entity group.

Abstract: Provided is a tabletop interface system. A tabletop input device diffuses an infrared light emitted based on at least one touch input from a user. A tabletop output device allows the diffused infrared light to pass therethrough to display content information corresponding to at least one touch point. The tabletop recognition device recognizes the at least one touch point by generating a touch image data based on the infrared light passing through the tabletop output device and generates touch point information by using the touch image data. The content server transmits the content information, which corresponds to the touch point information received from the tabletop recognition device, to at least one content client application.

Abstract: A collaborative virtual reality system and a method for molecular modeling are disclosed.
