Abstract: Provided is an apparatus and method for controlling legacy home appliances based on Zigbee wireless communication. The apparatus includes a home appliances control signal receiving unit for receiving a home appliances control signal from a user; a signal analyzing unit for analyzing the home appliances control signal and identifying a corresponding home appliance; a Zigbee coordinator for transforming the home appliances control signal into a Zigbee signal and transmitting the Zigbee signal to the identified home appliance; a Zigbee signal receiving unit for receiving the Zigbee signal from the Zigbee coordinator; an identification (ID) analyzing unit for analyzing the ID of the transmitted Zigbee signal; a signal transform unit for transforming the Zigbee signal into an infrared rays remote control signal; and an infrared rays signal transmitting unit for transmitting the infrared rays remote control signal to the infrared rays receiving unit.

Abstract: Disclosed are an apparatus and a method for controlling music play in a mobile communication terminal. The apparatus includes a motion recognition sensor unit for detecting a motion of the mobile communication terminal and outputting detection signals, a sound source chip for outputting sound, and a controller for receiving the detection signals from the motion recognition sensor unit, calculating motion values of the mobile communication terminal, and controlling the sound source chip to output sounds dependent on the calculated motion values. The apparatus includes a user interface required for the music play, a display unit for displaying music to be played, a motion recognition sensor unit for detecting a motion of the mobile terminal, a sound file storage unit including an area for storing at least one music information, a controller for controlling corresponding music to be played according a motion of the mobile terminal, and a speaker for outputting sounds of the played music.

Abstract: Disclosed are novel thermostable galactose isomerases and production of tagatose using the same. A gene encoding a galactose isomerase with improved thermal stability and reaction equilibrium is screened from natural genetic materials. An expression vector into which the gene is inserted is introduced into bacteria which are then cultured to obtain a thermostable galactose isomerase. In the presence of this enzyme, tagatose is produced from galactose in a yield as high as 46-50% at a temperature as high as 55° C.
