Abstract: A system and method of managing a social network are disclosed. The method includes the step of recording the IDs and corresponding personal information of users who have subscribed to a service via a network, in a user DB; the step of recording corresponding relationships between the users and relationship indices R, reflecting the degrees of trustworthiness of the users having the corresponding relationships, in a relationship information DB; and the path search step of evaluating one or more paths based on the relationship indices R of respective links constituting the paths and providing evaluation results to a first user so that the first user can select an optimal path from among the paths existing between the first user and a second user on the social network constructed with the users used as nodes and the corresponding relationships of the users used as the links.

Abstract: The present invention provides the steps of maintaining a first database containing profiles of a plurality of users in a network; maintaining a second database containing relationship index between some of the users wherein the relationship index is determined based upon degree of correspondence relationship between the users; forming a social network comprising a plurality of nodes and a plurality of links between at least some of the nodes, in association with the relationship index stored in the second database; upon receipt of a request from a first user, searching for at least one route connecting the first user to a second user in the social network based, at least in part, upon said existing links and the relationship index of the links; and evaluating each of the searched routes based, at least in part, upon the relationship indexes of the links which form said respective searched routes.

Abstract: Disclosed herein is a home network system interoperable with a wireless terminal of at least one user registered therein, wherein a terminal server is adapted to transmit and receive data to/from the wireless terminal, and a home server is adapted to manage/control a home network and communicate with the terminal server. The terminal server detects the position of the wireless terminal and transmits and receives voice messages, text messages or multimedia data to/from the wireless terminal. The home server is connected with the terminal server over the Internet. The home server sends, to the terminal server, alarm data regarding a dangerous situation in a home where the home network is constructed, receives information regarding the position of the wireless terminal from the terminal server and displays the received position information.

Abstract: It is an object of the present invention to provide a hollow fiber membrane module which maximizes the efficiency of removing scale-like contaminants generated at the water treatment using hollow fiber membranes, and a method of manufacturing the same. The hollow fiber membrane module includes hollow fiber membranes for making water treatment due to the pressure difference, and a collector fixing the hollow fiber membranes in bundle. A treated-water tube is extended to the inside of the collector, and communicated with the inner passage of the hollow fiber membranes to deliver the water treated through the hollow fiber membranes. A diffuser is installed at the collector to diffuse bubbles to the hollow fiber membranes. An air tube is extended to the collector, and connected to the diffuser to feed air. Dividers are installed over the collector to partition the hollow fiber membranes into a plurality of bundles.

Abstract: A portable device-interoperable home network system includes a home server controls data transmission and reception of an internal network to which a plurality of home appliances are connected in a home. An image server outputs information regarding at least one image in the home to the home server. A portable device server receives the image information from the image server via the home server and transfers it to a portable electronic device. Therefore, a user can recognize a situation in the home through the portable electronic device from anywhere outside of the home, resulting in an increase in convenience of use.

Abstract: A door lock includes a body, a locking device installed in part of the body to lock and unlock an entrance door and having a first handle provided at an inner side of the entrance door, a lock assembly engaged with the first handle when a normal key is inserted, and a locking member actuated by rotation of the first handle, a first sensing device which becomes an ON state as the locking member protrudes outside the locking device and an OFF state as the protruded locking member retreats, a speaker generating alarm when the first sensing device senses an intruder, and a power portion supplying electric power to the first sensing device and the speaker, wherein holes, through which the first handle and part of the first sensing device are exposed, are formed at an outer surface of the body, a cover is provided at a portion corresponding to the power portion, and the speaker is installed on the body so that sound is emitted out of the body.

Abstract: A mobile terminal is provided which includes a terminal main body, a folder having a main LCD mounted thereon, and a hinge device for combining the folder with a main body and having a sub-LCD mounted thereon. While using the main LCD, a user can check the terminal state. In addition, the sub-LCD can be used regardless of whether the folder is opened or closed, so that display efficiency can be maximized. Moreover, since the main LCD and the sub-LCD are mounted at different positions, a thickness of the terminal can be effectively reduced.
