Abstract: A display device includes a first electrode extended in a first direction, a second electrode spaced apart from the first electrode in a second direction and extended in the first direction, a first insulating layer on the first and second electrodes, light-emitting elements on the first insulating layer, each having at least an end disposed on the first electrode or the second electrode, a second insulating layer disposed on the light-emitting elements and extended in the first direction, and a first connection electrode disposed on the first electrode and electrically contacting the light-emitting elements, a second connection electrode disposed on the second electrode and electrically contacting the light-emitting elements. Each of the first and second connection electrodes includes a main portion electrically contacting the light-emitting elements, and a subsidiary portion having a width smaller than a width of the main portion and electrically connected to the main portion.

Abstract: The present invention relates to a novel pyrimidine derivative, and a composition for preventing or treating neurodegenerative diseases and cancer, comprising same, the pyrimidine derivative having a LRRK2 protein inhibitory activity, and effectively passing through a blood-brain barrier (BBB) so as to be effectively used as a pharmaceutical composition for preventing or treating neurodegenerative diseases and cancer.

Abstract: The present invention relates to an apparatus for controlling a cascaded hybrid construction machine system and a method therefor, which apparatus includes: a control part for controlling an electric motor for driving an actuator differently according to whether or not the actuator performs a recovery action and whether or not an energy storage device can be recharged; and a motor driver for driving or stopping the electric motor by switching under the control of the control unit, wherein when the actuator performs a recovery action for both the overcharged state and the failure state of the energy storage device, the motor for driving the actuator is temporarily stopped by the switching of the motor driver so as to restrain the recovery energy generated, thus protecting the hybrid power source system and keeping the operator safe as well as resolving the problem of the working time being increased due to the system's shutting off.

Abstract: A hybrid operation machine of which an electric motor is driven by at least one among a power generator driven by an engine and an energy storage system for storing regenerative energy, and comprising: a motor drive for driving the electric motor; an acceleration sensor for sensing an accelerator pedal command; and a control unit for mapping the accelerator pedal command to a speed command during a low speed traveling operation and controlling a traveling unit through the motor drive, wherein the control unit controls the acceleration and deceleration of the electric motor according to the mapped speed command and generates regenerative energy according to the deceleration of the electric motor.

Abstract: Provided is a method for fastening a separation type tricycle in which a connecting pipe for connecting a front wheel part and a rear wheel part can be separated from and fastened to a head tube of the front wheel part, wherein the front wheel part and the rear wheel part are separated from each other by forming an ear-shaped groove, in which a handle bar can be put, in a right-side-open rectangular shaped plate fixed to the end of the connecting pipe so as to be used for attachment/detachment in a fastening device of the head tube, and then the end of a connecting bar for connecting the front wheel part and the rear wheel part is put on the handle bar by using the groove and another place is fixed thereto so as to set three wheels at the shortest distance therewith, thereby conveniently moving and storing the tricycle.

Abstract: The present invention relates to a coupling method for a separable bicycle, in which the front wheel and the rear wheel are easily separated from and coupled to each other such that the front and rear wheels are firmly coupled to each other even if the separable bicycle is operated for a long period of time.
