Abstract: Proposed are a system and a method for position estimation and direction recognition between objects through a cooperative intelligent transport systems (C-ITS) linkage in a vehicle to everything (V2X) communication environment. The system may include an infrastructure information receiver configured to receive infrastructure information from an infrastructure, and an object position determination processor configured to determine a position of equipment in use. The system may also include an object position and path prediction processor configured to predict a future position and a movement path of the equipment in use and an object information transceiver configured to exchange information on the equipment with another object. The system may further include an object and surrounding situation recognition and determination processor configured to recognize an object and a surrounding situation and determine whether a dangerous situation exists by using information acquired through the C-ITS linkage.

Abstract: Disclosed are a thermoplastic resin composition and a molded product including the same, and based on 100 parts by weight of a base resin including (A) 70 wt % to 90 wt % of a polybutylene terephthalate resin and (B) 10 wt % to 30 wt % of an acrylate-based graft copolymer, the thermoplastic resin composition includes: (C) 1 part by weight to 5 parts by weight of an epoxy group-containing methacrylate-aromatic vinyl-unsaturated nitrile copolymer; (D) 15 parts by weight to 20 parts by weight of a carbon fiber; (E) 1 part by weight to 5 parts by weight of carbon nanotubes; and (F) 18 parts by weight to 20 parts by weight of aluminum diethyl phosphinate (ADEP).

Abstract: Disclosed are a focused ultrasound device and a method for setting an order of focused ultrasound treatment thereof. When using an ultrasound treatment method using mechanical energy, the focused ultrasound device according to an embodiment determines a next focal point position in consideration of at least one previous focal point position of focused ultrasound and thus can minimize thermal increase of an affected area and maximally utilize the mechanical energy.
