The present invention relates to a system and to a method for QoS (Quality of Service) support in a ubiquitous sensor network. The system for QoS support in a ubiquitous sensor network includes a mesh coordinator and nodes. The mesh coordinator organizes a super frame containing a dedicated QoS data transmission period, and synchronizes each of the nodes constituted into one network with the abovementioned super frame. The nodes create a beacon frame containing information on whether or not to set QoS, to broadcast the beacon frame in a dedicated beacon period of the super frame if QoS data transmission is needed, to create a QoS data frame with a set priority, and to transmit the QoS data frame to the dedicated QoS data transmission period of the super frame in the case of transmitting QoS data. The present invention divides QoS data from general data to improve the quality of data transmission and ensure stability, and prioritizes QoS data to transmit the most important data among QoS data in a quick and stable manner.

A local wireless signal transmitting/receiving apparatus and method using digital RF processing technology. When the local wireless signal transmitting/receiving apparatus generates a local wireless signal to be transmitted, spreads the frequency of the generated local wireless signal and thereby generates a baseband signal, the local wireless signal transmitting/receiving apparatus converts the baseband signal of the local wireless signal into phase information, converts the phase information into an RF signal by means of a polar modulator, and transmits the RF signal.

The present invention relates to a mixed ink mixed with a far-infrared-emitting material, a method for preparing the mixed ink, and a printed matter on which the mixed ink is printed, wherein the mixed ink is a printing ink used in a printing process for a printed matter and the mixed ink is prepared by mixing a pigment mixture with a powder type far-infrared-emitting material. Therefore, a mixed ink, which is to be printed on an object, is mixed with a far-infrared-emitting material to maintain a high far-infrared emissivity of 0.88 or greater, so that 60% or more of various noxious gases, which are generated from the printed matter, can be deodorized to allow a user to use the printed matter without repulsion; about 90% or more of staphylococci and pneumococci can be reduced to maintain cleanliness; and the contamination and pathogen transmission due to the use of the printed matter can be prevented in advance.

A method for assigning a channel in multi-FA CDMA mobile communication system according to the received power prevents communication quality of a FA from being inferior to that of the others by managing the interference level of the FA. The method comprises the steps of: comparing a first threshold value with received power when the base station receives a new call request; assigning a traffic channel in a first FA of the request, if the received power is less than the first threshold value, and searching a second FA of which received power is least, if not; comparing a second threshold value with the received power of the second FA; and assigning a traffic channel in the second FA if the received power is less than the second threshold value, and rejecting the request, if not.
