Abstract: The present invention relates to a microorganisms of the genus Corynebacterium producing 5?-inosinic acid, in which the expression of genes encoding purine biosynthesis related enzymes is increased higher than the intrinsic expression, and to a method for producing 5?-inosinic acid, comprising culturing the microorganisms of the genus Corynebacterium with improved 5?-inosinic acid productivity.

Abstract: The present invention relates to a microorganism with improved production of 5?-xanthosine monophosphate and 5?-guanine monophosphate, and more specifically, to a Corynebacterium sp. microorganism having increased proline dehydrogenase activity compared with an intrinsic activity thereof, a method for producing 5?-xanthosine monophosphate or 5?-guanine monophosphate from the culture medium obtained by culturing the transformed microorganism, and a use of the microorganism for production of 5?-xanthosine monophosphate or 5?-guanine monophosphate.

Abstract: A portable device for data communication using a body as a conductor to transmit data to a receiver, the portable device includes a data receiving unit to receive data, a controller unit to control processing of data to be transmitted, a current limiting circuit to limit a current of a signal corresponding to the data to be transmitted to a predetermined value, and transmitting electrodes connected to the current limiting circuit and to contact the body to transmit the signal having the current of predetermined value to the receiver.

Abstract: The present invention provides method and system for data communication in the human body and a sensor therefor. The method and system transmit information through the human body to a receiver located outside the human body using low current and voltage polarity, so that they cause no damage to the human body and achieve low power consumption and better receiving sensitivity. In addition, the sensor contains a CMOS image sensor on which all circuits are integrated without radio transmitter and antenna, so that it achieves a low-priced and small-sized capsule type endoscope.
