In a method for providing multimedia services in a communication system, a request message for requesting contract information on users' multimedia services are received from a terminal according to service requests of the multimedia services to be received by the users. A query message for searching for the contract information in a database is generated corresponding to the request message, and the query message is transmitted to the database. The contract information is searched in the database through a Moving Picture Experts Group (MPEG) query format protocol based on the query message, and a query result message containing the contract information is received from the database in response to the query message. The contract information is acknowledged in the query result message, and a response message containing the contract information is generated. Then, the response message is transmitted to the terminal.

A method of fabricating a semiconductor device having a silicon nitride layer substantially free of impurities includes forming a silicon nitride layer on a semiconductor substrate and annealing the semiconductor substrate having the silicon nitride layer in an atmosphere of ammonia (NH3) gas to remove impurities from the silicon nitride layer. The silicon nitride layer may be formed using BTBAS as a silicon precursor.

The present invention pertains to a sensor for a diagnostic device using an optical fiber and a pH sensitive high molecular weight substance, which indicates the safety of foodstuffs or is used as a medical examination device. More particularly, the present invention relates to a sensor for a diagnostic device which detects a wavelength change of reflected light using an optical spectroscope to indicate a freshness of foodstuffs or an immune condition of a human body, including a light receiving optical fiber through which light is transferred from a light source to a pH sensitive high molecular weight substance. The sensor also includes a semi-permeable membrane film part which is filled with the pH sensitive high molecular weight substance so as to detect a pH change of a subject when the subject comes into contact with the pH sensitive high molecular weight substance, receives an output end of the light receiving optical fiber and an input end of an information transferring optical fiber, and includes a reflection member inserted therein so as to reflect the light passing through the light receiving optical fiber into the information transferring optical fiber. The information transferring optical fiber transfers data including the freshness of the foodstuffs or a health condition of the human body therethrough when the light subjected to a wavelength interference by the pH sensitive high molecular weight substance advances into the optical spectroscope. Alternatively, the sensor for the diagnostic device may includes a diagnostic kit insertion member instead of the semi-permeable membrane film part. The diagnostic kit insertion member is made of a material having excellent light transmittance, receives an output end of the light receiving optical fiber and an input end of the information transferring optical fiber, and has a diagnostic kit insertion groove for receiving a diagnostic kit. At this time, the diagnostic kit includes a semi-permeable membrane member and the pH sensitive high molecular weight substance. Accordingly, the sensor for the diagnostic device according to the present invention is advantageous in that it has a relatively short diagnostic time and excellent sensitivity and selectivity to a specific substance. Outer advantages are that the sensor may be repeatedly used many times and applied to various fields, and various diagnoses can conducted for a relatively short time through a simple operation in which various diagnostic kits are replaced with each other.

Disclosed herein are an apparatus and method for generating polite expressions for automatic translation. The apparatus includes a relationship recognition unit, a polite level selection unit, and a translation unit. The relationship recognition unit extracts relationship information from a conversation between first and second language users and personal information of the first and second language users and then recognizes the social relationship between the language users. The polite level selection unit selects a polite level for the conversation between the first and second language users based on the extracted relationship information. The translation unit generates polite expressions corresponding to the selected polite level, and translates the conversation between the first and second language users into a target language based on the generated polite expressions.
