  • Publication number: 20200130735
    Abstract: The present disclosure provides a steering control method and system for rear-wheel steering that improves driving stability and yaw responsiveness of a vehicle by controlling rear wheels on the basis of a driving state of a vehicle. The method and system receives a vehicle speed and a front-wheel turning angle and calculates a rear-wheel same/inverse-phase control amount; estimates tire slip angles when the vehicle is driven such that the rear wheels are controlled with the same phase; calculates a final rear-wheel turn control value by reflecting a control weight proportioned to the tire slip angle estimation value to the rear-wheel same-phase control amount; and turns the rear wheels on the basis of the final rear-wheel turn control value.

  • Publication number: 20200030246
    Abstract: The present invention aims to dramatically increase the effect of hepatic arterial chemoembolization by developing human serum albumin-based nanoparticles, which are bioproteins that effectively carry Adriamycin in place of Adriamycin, an anticancer agent used in hepatic arterial chemoembolization. The human serum albumin nanoparticles carrying the Adriamycin not only intensively infiltrate the drug effectively into the cells but also have a synergistic effect that can induce a long-term therapeutic effect by utilizing the effect of continuous drug release from the particles.
