A semantic service discovery technology is provided. A semantic service discovery method includes: receiving a query for a service discovery from a user equipment (UE); analyzing the received query; conducting an ontology-based analysis of semantic information of the analyzed query; and generating a query for the service discovery by putting the analyzed semantic information together, converting the generated query into an ontology query, and discovering services using the ontology query. Therefore, a service desired by a user can be discovered through a semantic approach.

Provided are a method and apparatus for advertising a service in a personalized manner in a next-generation communication network. The method includes: receiving new service registration information, which indicates that a new service has been registered, from a service registration server; mapping the received new service registration information to service profiles included in pre-stored subscription information of a plurality of subscriber terminals and selecting a subscriber terminal which is related to the new service registration information; and identifying whether the selected subscriber terminal is subscribed to a new service notification event of a home subscriber server and sending advertising information of the new service, which is related to the new service registration information, to the selected subscriber terminal with reference to subscription information of the selected subscriber terminal.

A color alignment adjustment method and apparatus for adjusting the color alignment of a color image forming apparatus by using patterns formed on a middle transfer belt or a photosensitive body of the color image forming apparatus are provided. The color alignment adjustment apparatus includes a sensor which radiates light onto the patterns, detects the amount of light reflected from the patterns, and outputs a signal based on the detection result, a memory which stores pattern information regarding the patterns, a variation detection unit which detects a plurality of portions of the output signal of the sensor that match the pattern information stored in the memory and calculates variations in the locations of a plurality of colors that can be printed by the image forming apparatus based on the locations of the detected portions of the output signal of the sensor and a print location adjustment unit which adjusts the locations of the colors based on the calculated variations.

A transfer unit of an image forming apparatus includes at least one support roller; a transfer belt driven and supported by the support roller; and a meander preventing unit to prevent the transfer belt from leaning to one side with respect to an axial direction of the support roller. The meander preventing unit includes a guide rail disposed between one side of the belt and the support roller supporting the belt to guide the belt running; and a belt pressing member disposed on the opposite side of the belt to compensate for the belt leaning caused by the guide rail.
摘要:
An apparatus and method for perceiving a physical and emotional state, which allows easy attachment to and detachment from a human body, and through which a bio-signal is simply detected, are provided. The apparatus includes a bio-signal detection part attached to a predetermined portion of a body for performing analog signal processing on at least one bio-signal detected from the body and outputting the processed bio-signal, and a bio-signal recognizing part for performing digital signal processing on the processed bio-signal received from the bio-signal detection part, perceiving the physical and emotional state from the result of the digital signal processing, and representing the physical and emotional state. Accordingly, the apparatus can be conveniently attached to a predetermined portion of a user's body, a bio-signal transmitted wirelessly or through a wire can be easily detected, a physical and emotional state which is perceived based on the detected bio-signal can be reported to the user, and a rapidly changing emotional state or an emotional state which remains for a long time can be perceived in real time.
