Abstract: A knee joint rehabilitation apparatus for a wheelchair includes a rehabilitation apparatus frame having a height corresponding to a length of each of legs of a patient sitting on the wheelchair; an upper leg support disposed at an upper end of the rehabilitation apparatus frame and supporting upper legs of the patient thereon while the patient is sitting on the wheelchair; a lower leg support pivotably connected to the upper leg support, wherein the lower legs of the patient are seated and supported on the lower leg support; and an exercise control unit disposed on the rehabilitation apparatus frame and configured to allow the lower leg support to pivot around a connection portion between the lower leg support and the upper leg support such that the patient performs rehabilitation exercise of the knee joint thereof while sitting on the wheelchair.

Abstract: Disclosed is an exoskeleton-type rehabilitation robot system, including: a body part provided on a chair in which a user sits and provided with a robot arm capable of moving left or right based on the user seated on the chair; a conversion part configured to convert a position of the robot arm with respect to the body part; a driving part configured to articulate the robot arm with respect to the body part; and a controller configured to detect a change in a position of the robot arm and control a left or right driving mode of the driving part according to the position of the robot arm. In accordance with such a configuration, the exoskeleton-type rehabilitation robot system of the present invention is provided integrally with a chair, thereby having excellent space utilization. In addition, the user's initial preparation for rehabilitation training is simple, which can improve efficiency.

Abstract: An integrated circuit device includes a lower electrode, an upper electrode, and a dielectric layer structure between the lower electrode and the upper electrode, the dielectric layer structure including a first surface facing the lower electrode and a second surface facing the upper electrode. The dielectric layer structure includes a first dielectric layer including a first dielectric material and a plurality of grains extending from the first surface to the second surface and a second dielectric layer including a second dielectric material and surrounding a portion of a sidewall of each of the plurality of grains of the first dielectric layer in a level lower than the second surface. The second dielectric material includes a material having bandgap energy which is higher than bandgap energy of the first dielectric material.

Abstract: Disclosed are an earthquake monitoring device and a method of installing the same, which can permit stable and efficient installation and operation on any ground surface with free-field conditions including level and sloped ground conditions, and can provide precise monitoring results of earthquakes. The earthquake monitoring device includes a sensor for sensing vibration; and a base having an upper surface formed into a leveled surface, wherein the sensor is secured to the upper surface, and the base is placed on an excavated ground such that the upper surface of the base is positioned on a ground surface or the sensor on the upper surface of the base intersects the ground surface.

Abstract: A cylindrical lever lock using a lever as a handle for convenient use by even the disabled and the old is disclosed. Since plate shafts, spring holders and spring cage covers constituting the cylindrical lever lock are made of general metal plates, the material cost and the prime cost may be reduced. In addition, the spring holders are connected through double engagements with spring cages and the spring cage covers. Therefore, deformation of parts or drooping of levers may be prevented in spite of an excessive force applied. Furthermore, assembling and disassembling of the parts can be quickly and easily performed by achieving adjustment of intervals of the parts according to thickness of a door using a female screw of an outer attachment plate and a male screw of a boy assembly.
