20130225696 | pH-SENSITIVE POLYMER HYDROGEL WITH DUAL IONIC TRANSITION AND USE THEREOF - Disclosed is a dual-transition polymeric hydrogel. Also, provided is the use of the dual-transition polymeric hydrogel as a carrier for drug delivery and disease diagnosis, or in the preparation of a polymeric hydrogel-type pharmaceutical composition comprising the physiologically active agent loadable into the block copolymer. Being sensitive to pH as well as temperature, the block copolymer can form a more stable hydrogel at suitable temperatures and pH values. In addition, the block copolymer exhibits a dual transition behavior with pH values so that it can carry ionic drugs, proteins, DNA, and markers, whether positively or negatively charged, simultaneously. Therefore, it can be applied to a sustained drug delivery system for sparingly soluble, hydrophobic drugs, and hydrophilic drugs. Further, it is safe to and stable within the body, and is expected to find various applications in the medical field. | 08-29-2013 |
20130261424 | System for Inducing Respiration Using Biofeedback Principle - Disclosed herein is a system for processing a biofeedback-treated, respiration-induced signal image using the biofeedback principle, wherein a process for processing the respiration-induced signal image comprises the steps of: (a) acquiring a respiration-induced signal image from a treatment site of a patient in need of radiotherapy treatment using a photographing device; (b) binarizing the acquired image of step (a) using a threshold value; (c) determining whether the binarized image of step (b) is distorted; (d) synthesizing the image; (e) determining whether the synthesized image is required to be separated into regions; and (f) performing pattern matching for the respiration-induced signal image. According to the system, a patient can see and control the patient's own motion at a place where the patient's steady respiration or motion is required, and thus the stability of the patient in a radiotherapy treatment process can be ensured. | 10-03-2013 |

20140074369 | METHOD FOR CONTROLLING BRAKING OF VEHICLE - A method for controlling braking of a vehicle calculates a driver request braking deceleration and a current frictional coefficient of a road surface to obtain a vehicle deceleration corresponding to the coefficient of the road surface. A maximum deceleration at which a wheel lock, does not occur upon braking only by a driving wheel is calculated When the driver deceleration is equal to or smaller than the coefficient by comparing the driver deceleration and the vehicle deceleration. A braking force is determined by distributing a regenerative braking force of the driving wheel and a frictional braking force of a driven wheel according to the coefficient when the maximum deceleration is smaller than the driver deceleration by comparing the maximum deceleration and the driver deceleration. A driving motor and a frictional braking device are controlled to generate the determined regenerative braking force and frictional braking force. | 03-13-2014 |
