Abstract: A sound control device in a vehicle and control method thereof may include obtaining energy per unit time of an audio signal corresponding to a preset low frequency band, calculating an allowable reference value based on a difference between a magnitude of energy per unit time of the audio signal and a magnitude of a preset maximum allowable input of a speaker, monitoring whether a magnitude of energy per unit time of a noise control signal for eliminating noise in the vehicle exceeds the allowable reference value, and adjusting a magnitude of the noise control signal when the magnitude of energy per unit time of the noise control signal exceeds the allowable reference value.

Abstract: An aspect of the present invention relates to an endoscope system which can be inserted into the body of a subject to examine or treat tissue or the like and, more specifically, to an endoscope system in which an operation of bending a bending section of an insertion tube is motorized, and thus convenience in a surgeon's manipulation is ensured.

Abstract: A motor-driven endoscope includes: an insertion unit which is configured so that at least a part from one side thereof, and which includes a curve unit that is configured to be bent when being pulled by a wire inserted therein; a grip unit which is provided at one side of the insertion unit and is held by a user to input a driving input; a plurality of motors for transferring driving power so as to steer the curve unit; and a tension adjustment unit which is provided at the other side of the insertion unit and receives a rotating force from the motors to pull each wire, wherein the tension adjustment unit and the motor are configured to be coupled to or uncoupled from each other, and the tension adjustment unit is configured to receive the rotating force from the motor when coupled to the motor.

Abstract: A dendrimer type or dendrimer-derived metal nanostructure may be very easily obtained from a metal precursor and a reducing agent in a liquid-liquid interface between different liquids which form the interface. The metal nanostructure may have, particularly, a low-dimensional structure. In addition, a plurality of nanogaps may be formed between many small branches.

Abstract: The treatment device for hemiplegia comprises a robot which is putted on the hemiplegic side of the body of a subject; a motion measurement unit for measuring the motion of the healthy side of the body of the subject; and a control which is connected with the robot and the motion measurement unit, wherein the control unit is configured to receive the healthy side's motion measured by the motion measurement unit and to control the robot, whereby the hemiplegic side having the robot put thereon moves in accordance with the motion of the healthy side of the body.

Abstract: The present invention discloses a laser emission system comprising a laser emission device for irradiation a laser to an area of a targeted object; a monitoring device; a display unit for displaying an image captured by the monitoring device; and a control unit connected to the monitoring device and the display unit. Here, the control unit receives the information on a movement direction and a moving distance of the laser emission device and distinguishes between an area emitted with a laser by the laser emission device and an area which is not emitted with a laser, and then displays them on the display unit. Regardless of the perceived skill of the operator, the present invention prevents the irradiation of the area from being omitted and prevents the area from being excessively or insufficiently emitted in the laser treatment.

Abstract: The present invention provides a hybrid material comprised of an active component for raw materials for cosmetics and a layered metal hydroxide, showing good stability, low toxicity, low irritation, good sustained release and good dispersibility. The present invention provides a method for preparing the hybrid material, using the coprecipitation method, the ion-exchange method or the adsorption method, depending on properties of the active component for raw materials for cosmetics. The method may further comprise a step of coating the surface of the hybrid material after preparation of the hybrid material. The present invention provides cosmectics comprising the above hybrid material.
