Abstract: An artificial marble chip of the present invention comprises curable resin, metal fiber and/or inorganic fiber, and inorganic filler. The metal fiber and/or inorganic fiber preferably have an average length of about 1 to about 6 mm and an average particle diameter of about 10 to about 15 ?m. An artificial marble according to the present invention is produced by using the artificial marble chip, curable resin matrix, and inorganic filler as main components. The curable resin is preferably selected from acrylic resin, unsaturated polyester resin, epoxy resin, or a copolymer thereof. The artificial marble according to the present invention is produced by the steps of: producing an artificial marble composition by mixing the artificial marble chip, the inorganic filler, and other additives into the curable resin matrix; and curing the composition at about 25 to about 180° C. The invention can also include the step of defoaming the composition prior to curing.

Abstract: Endoscope manipulator for MIS can overcome disadvantages of multiaxial endoscope manipulator including conventional robot arm and provide compact and lightweight structure to obtain maximum activity space for medical staff. According to the endoscope manipulator for MIS, multi-joint arm is configured so that movement of all of the joints from base link to tip link is manually locked and unlocked by user and not controlled by motors. Additionally, endoscope mounted on an end of multi-joint arm is manipulated using motors to enable movement of three degrees of freedom, thereby accomplishing compact and lightweight endoscope manipulator. Additionally, tube of endoscope can be press-fitted onto tip part of multi-joint arm, and triaxial movement function for vertical, horizontal and forward/backward conveyance of endoscope is implemented in the tip part of multi-joint arm.

Abstract: Provided are a method and apparatus for processing an image. The method includes receiving a first luminance image of an image including airlight, which is a type of light that occurs in a foggy environment, and generating an airtight map based on a ratio between an average luminance of the first luminance image, and a standard deviation; and removing the airtight by subtracting the airtight map from the first luminance image and outputting a second luminance image. According to the present invention, airlight components may be effectively removed.

Abstract: A robotic surgical system includes a master manipulator, slave robotic units having a surgical instrument for performing a Minimal Invasive Surgery (MIS), and a control system for electrically associating the master manipulator with the slave robotic units. The slave robotic unit includes the driving mechanisms which are more compact than those of the conventional MIS system. In use, the existing surgical instruments used in the conventional MIS procedure can be applied to the slave robotic unit. Moreover, by using the pivotal mechanism of the driving mechanisms, a pivot point of the surgical instrument is allowed to be shifted with respect to an incision of a patient. So, the patient's tissues surrounding the surgical instrument are not excessively affected by the surgical instrument during the procedure.
