The present invention relates to a game server and method for recommending a guild suitable for a user, and more particularly, to a game server and method for recommending a guild suitable for a user, which recommends guilds to a user in the order in which time and levels of guilds executing a game are maximally identical to the time and level of the user executing the game, wherein a weight is set for the time or level of a game being executed. To this end, a game server for recommending a guild suitable for a user according to the present invention comprises: a game request receiving unit for receiving a game execution request signal from a terminal; a user information extracting unit for extracting user information of the terminal from a user database (DB); a code storage unit for storing a reference-based code value according to preset references in a code DB; a terminal code generating unit for extracting the reference-based code value according to the user information of the terminal using the code DB, and generating a reference-based terminal code value; a guild code generating unit for extracting the reference-based code value according to each game guild using the code DB, and generating a reference-based guild code value according to each game guild; a suitable value unit for giving a weight according to the preset references, and calculating a suitable value according to each game guild, in which the weight is reflected, using the reference-based terminal code value and the reference-based guild code value; and a guild recommending unit for recommending a guild suitable for the user of the terminal using the suitable value according to each game guild obtained by the suitable value unit. Accordingly, since a guild suitable for a game character of a user is recommended, the user does not need to search for a guild in cyberspace in order to select a suitable guild, enabling the user to have free time.

Disclosed are a preparation method of soil reinforced with a bio-binder using a microorganism, and soil prepared thereby, wherein the soil is harmless to the human body and does not cause environmental pollution, and the strength and wind resistance of the soil are sufficient. The method and soil is prepared by combining sand comprising silica and alumina as main components, a microorganism producing urea, urea, a calcium ion, and a polymer fiber, wherein the amount of the polymer fiber is 0.05-5 wt% on the basis of the amount of the sand. In addition, the microorganism preferably provides a CaCO3 production rate of 1-7×10-9 (g CaCO3 ppt cell-1 hr-1) in the standard state.

The present invention relates to a system for providing a card item and to a method for same, and more specifically, to a system and a method for providing a card item which allows each user to use different types of cards in online card games, such as poker or Go-Stop, so that a card arrangement in which the order of cards is pre-arranged so as to yield a specific result can be used. To this end, the present invention comprises: an item DB for saving information with respect to a plurality of card items; a condition DB for saving information with respect to limitation conditions that limit the application of the card items; an item advertisement portion for providing to a user terminal information with respect to the card items that is saved in the item DB; an item combination portion for completing a card by combining card items, which are selected by the user from the card items that are advertised through the item advertisement portion; and an item application portion for applying the card items that are combined in accordance with a condition that is set in the condition DB and providing same to the user terminal.

The present invention relates to a locking apparatus with enhanced security using an iris image, wherein, if a terminal including a wireless local-area communication means and camera accesses the locking apparatus, the locking apparatus: transmits, a token comprising at least one identification number and/or random number of the locking apparatus from a token generator mounted on the locking apparatus, to the terminal; requests an iris image be photographed and transmitted within a preset time period; generates an iris template from the iris image photographed by a camera fixed on the user terminal; encrypts and transmits the generated iris template and the token from the terminal to the locking apparatus using wireless local-area communication; and performs at least one or more of access permission, access denial, request to rephotograph, and alarm by decrypting the received encrypted iris template and token using a decoder mounted on the locking apparatus, and comparing the similarity thereof with an iris template registered and stored in a database in advance.

The present invention relates to a computed tomography device using x-rays, and comprises: a scan module (10) for performing computed tomography, which comprises an x-ray light source portion (12) for generating x-rays and an x-ray sensor portion (14) for receiving and transforming the x-rays that are generated from the x-ray light source portion into an electrical signal; a transport module (20), on which the scan module (10) is installed, for linearly shifting the scan module (10); a rotation module (30) for rotating the transport module (20); a case (40) to which the rotation module is fixed; and a stage module (50) for moving an object (90) to be inspected in between the x-ray light source portion (12)and the x-ray sensor portion (14), wherein the object (90) can be captured from a variety of angles and even can be captured from a discretionary position by adjusting magnifying power by rotating the x-ray light source portion (12) and the x-ray sensor portion (14) of the scan module to various angles while the object (90) is in place.

The present invention relates to a method for determining a data routing path in a communication network in which a plurality of logical networks share one physical network, and more particularly, to a method which: generates multiple routing paths from a source node to a destination node according to dynamic state changes of multiple nodes constituting a logical network; and calculates a routing cost of the multiple routing paths from a routing registry message received from the multiple nodes and from a processing-time shift value and a transmission-time shift value, shared by the multiple nodes, thereby determining the data routing path.

The present invention relates to a thermal medium direct-heating type dual vacuum tube heat collector. A dual vacuum tube communicating with a head includes a nonmetallic barrier that is disposed within the dual vacuum tube to define a passage spaced apart from an inner surface of the dual vacuum tube. Thus, solar heat collected directly into the dual vacuum tube may be transferred into a thermal medium, and also the area of contact with the vacuum tube may be expanded, and the heat absorption time may be increased to obtain high thermal efficiency and a high temperature.
