Abstract:
Provided is a method of using any mammal except humans, in particular, a mammal as an attention deficit hyperactivity disorder model, wherein genes of G protein-coupled receptor kinase interacting protein 1 (GIT1) as a neuronal synapse protein in the brain are knocked out from the mammal. In addition, disclosed is analysis of GIT1 knock-out mice in aspects of molecular biology, cellular biology, electrical biology and animal behavior and, more particularly, a screening method of novel drug, wherein excessive behavior as an attention deficit hyperactive disorder as well as recovery of theta wave in the frontal lobe are observed by administering a candidate material of the drug, thereby inducing recovery of the attention deficit hyperactivity disorder.
Abstract:
The present invention relates to a bio-silica chip comprising a silica-binding protein and a fabrication method thereof, and more particularly to a bio-silica chip in which a fusion protein of a silica-binding protein and a probe protein is immobilized on a chip comprising a silica layer, a fabrication method thereof and a method of using the bio-silica chip to detect interactions with biomaterials. The bio-silica chip will be very useful in biosensors, etc., because the bio-silica chip is advantageous in that it does not cause non-specific protein binding in the detection of protein-DNA, protein-ligand, protein-antibody, protein-peptide, protein-carbohydrate, protein-protein and cell-biomaterial interactions. Also, in the method for fabricating the bio-silica chip, a probe chip can be selectively immobilized on a silica device chip, which is widely used in biosensors, without a chemical surface treatment process. Thus, a chip fabricating process is simplified and a complicated process for purifying the probe protein becomes unnecessary, thus providing great improvements in productivity and economic efficiency.

Abstract:
There is provided a multi-mode power amplifier operable in a low power mode having a preset power range and in a high power mode having a power range higher than the power range of the low power mode. The multi-mode power amplifier includes: a high power amplifying unit including at least one cascode amplifier to amplify an input signal to a high power level having a preset power range; a low power amplifying unit sharing a common source node of the at least one cascode amplifier to amplify the input signal to a low power level having a power range lower than the high power level; and a coupling unit coupling a transfer path of a signal output from the high power amplifying unit and a transfer path of a signal output from the low power amplifying unit to each other.
Abstract:
Disclosed is a length-variable bumper capable of adjusting the length of a vehicle body to lengthen a time interval over which momentum changes upon collision. The length-variable bumper includes a bumper member primarily absorbing collision energy, a collision energy absorbing member foldable in a longitudinal direction, and an operation unit configured to transit the collision energy absorbing member to an unfolded state when a vehicle speed is a predetermined level or more and to transit the collision energy absorbing member to a folded state when the vehicle is the to predetermined level or less. The collision energy absorbing member has one end connected to a frame of the vehicle and the other end connected to the bumper member and configured to be deformed upon collision to secondarily absorb the collision energy.
