Abstract: Provided is an apparatus for diagnosing a disease, which includes an acquisition module configured to acquire multi-modal data including at least two types of data among text data, speech data, and image data related to each depression patient, a preprocessing module configured to visualize data that is not the image data among the multi-modal data and output image datasets including the image data among the multi-modal data and the visualized data, and a classification module configured to classify whether each depression patient has depression based on the image datasets.

Abstract: The present disclosure relates to a rotation prevention member of a leg screw for fixing a bone that is configured to prevent rotation of a leg crew that is coupled to a nail in a medullary cavity such as a femur and fixes a fracture portion. The rotation prevention member of a leg screw for fixing a bone, in which a femoral nail is fitted in an end of a femoral marrow, a leg screw combined with a cap is laterally inserted in a transverse hole formed at an angle with respect to a longitudinal axis of the nail, and the leg screw is fixed to be longitudinally movable without rotating in the transverse hole, includes: pin guide grooves formed symmetric to each other in a longitudinal direction of the leg screw; a superelastic member inserted in the pin guide grooves; and a cap thread-fastened to a rear surface of the leg screw to prevent separation of the superelastic member in order to prevent rotation between a threaded portion of the leg screw and a bone due to rotation after a fracture part is occupied.

Abstract: The present disclosure relates to a surgical aiming device 1 that prevents a sleeve from being pushed backward or shaken when a drill or a leg screw is implanted after a guide sleeve is mounted on an aiming device. The surgical aiming device includes: a body 20 having an aiming arm 21 and a barrel 22; a guide sleeve 30 disposed at an end of the aiming arm 21 and guiding a nail 10 and a leg screw 12; and a knob 40 for detachably attaching the guide sleeve 30, in which the guide sleeve 30 can be detachably attached in a one-touch type by a guide sleeve attachment/detachment unit 100 installed at an end of the aiming arm. The guide sleeve attachment/detachment unit 100 includes: an operation unit 21a installed at an end of the aiming arm 21; a button 110 installed at the operation unit 21a and partially exposed to the outside; an operation lever 120 being rotated on a rotary shaft by operation of the button 110; and a threaded portion 30a controlled by the operation lever 120 and formed on the guide sleeve 30a.

Abstract: A roller shoe has a pliable bottom. Rear wheels are independently rotatable about a rear axle recessed in the heel portion. A front wheel is rotatable on a front axle recessed in the arch portion. Both axles are removably yet firmly supported partially recessed within wheel housings. Rolling with front and rear wheels on a flat skating surface holds the forward portion of the shoe bottom clear of the skating surface. Tilting forward onto the front wheel alone allows pivoting while rolling. Tilting farther forward brings the forward portion down to sliding, standing or walking contact with the skating surface. Tilting backward onto the rear wheels alone allows pivoting while rolling. Tilting backward in the extreme brings the shoe heel into sliding or resting contact with the skating surface. Wheels are formed of urethane, axles and bearings of steel, shoe of textile or leather, shoe bottom of resinous or rubber material, and wheel housings of strong plastic such as nylon.
