Abstract: A wind-direction adjustable air purifier according to an embodiment of the present invention comprises: a housing provided with an air discharge opening formed on one surface thereof; an air guide having a front end disposed in a center of the air discharge opening and a rear end extending toward the other surface of the housing such that the air discharge opening has a ring shape; and a rotation guide coupled to the inside of the housing so as be rotatable in the circumferential direction of the air discharge opening, and supporting the air guide in by the housing, wherein the air guide can be coupled to the rotation guide so as to be rotatable in a direction inclined relative to the air discharge direction of the air discharge opening.

Abstract: The present disclosure provides a composition for promoting hair growth including camellia kaempferol glycoside as an active ingredient. The composition for promoting hair growth according to an aspect of the present disclosure can promote hair growth by promoting the proliferation of hair follicle cells without side effects. In addition, the composition for promoting hair growth can promote hair growth and prevent hair loss by inhibiting the apoptosis of outer root sheath cells. Such a composition for promoting hair growth can be used as an external application to the skin, and can be used as a food, cosmetics or pharmaceutical composition.

Abstract: The present invention relates to a real-time parathyroid imaging device, and a real-time parathyroid imaging device for displaying only a parathyroid in a thyroid with a separate mark, the real-time parathyroid imaging device including: a light source configured to emit light to a thyroid and excite a parathyroid; a detector configured to detect an emission spectrum of the parathyroid excited and emitted by the light source; an excitation filter disposed in front of the light source; and an emission filter disposed in front of the detector. When central Compartment Neck Dissection (CCND) for thyroidectomy is performed, the present invention clearly marks a parathyroid by an autofluorescent image, thereby allowing a surgeon to more simply and safely perform the CCND while leaving the parathyroid.

Abstract: A gateway device includes: a communicator configured to communicate with a user terminal and a smart key device; and a controller configured to; transmit a search signal for communication connection through the communicator; transmit a turn-on signal to the smart key device when a response signal corresponding to the search signal is received from the user terminal; and control the communicator to transmit a control signal to the smart key device when the control signal is received from the user terminal.

Abstract: The present invention relates to a composition for preventing or treating stenosis, in which the composition includes brown algae extract, and more particularly to a composition for preventing or treating stenosis, in which the composition includes brown algae-derived polyphenol as an active ingredient, thereby providing excellent prevention or treatment effect on stenosis including tracheal stenosis, glottic stenosis, vascular stenosis, and the like.

Abstract: A vehicle may include an auxiliary battery to prevent full discharge of a main power source while remotely controlling electronic devices of the vehicle, wherein the vehicle may include a communication device configured to receive a control signal indicating a control command from a mobile device; a controller configured to control a target of control based on the control signal; and a power management device including an auxiliary battery and configured to supply power to the controller using the auxiliary battery when the communication device receives the control signal while an ignition of the vehicle is turned off.
