Abstract: A linear actuator having a free fall function. The linear actuator moves a piston-rod member back and forth using torque of a rotary motor. Here, the piston-rod member is disposed within a portion of a cylinder body to be movable back and forth. In the event of jamming in which the piston-rod member is stopped due to sticking between an operating nut and a screw member, the piston-rod member is caused to freely fall in a direction in which load is applied. This can consequently obtain the maximum stretched length of the piston-rod member, thereby providing safety in an emergency.

Abstract: The present invention suggests a holographic optical element which forms a pattern according to a transmissive hologram recording method based on a multi-diverging object beam and a reference beam, a method for generating the same, and a screen device including the holographic optical element. The holographic optical element according to the present invention includes a base film and a pattern which is formed on the base film by using a transmissive hologram recording method based on a multi-diverging object beam and a reference beam.

Abstract: The present invention relates to an anticancer adjuvant containing, as an active ingredient, protopanaxadiol (PPD) or a compound-K, which are types of panaxadiol ginsenoside compounds, and a pharmaceutical composition for treating cancer containing the anticancer adjuvant and an anticancer agent having mitochondria-mediated anticancer activity. The anticancer adjuvant containing the PPD or compound-K provided in the present invention as an active ingredient damages mitochondria in cancer cells, thereby aiding mitochondria-mediated anticancer activity, and thus can be widely used in safer treatment or alleviation of cancer using anticancer agents that exhibit mitochondria-mediated anticancer activity.

Abstract: An autostereoscopic 3D display device is disclosed. The device includes a first light source and a second light source configured to alternately generate light and a light guide panel arranged to guide the light from the first light source in a first direction as a first light beam and the light from the second light source in a second direction as a second light beam. In the device, a stack of a plurality of holographic optical elements is configured to converge the first light beam and the second light beam from the light guide panel. The stack of the plurality of holographic optical elements may include at least one first holographic optical element and at least one second holographic optical element.

Abstract: The present invention is directed to a method for screening a regulator of mitochondrial fission using a cell treated to a protopanaxadiol (PPD)-type ginsenoside compound, a composition therefor, and a kit comprising the composition. As the use of the method for screening the regulator of mitochondrial fission of the present invention enables effective discovery of a formulation capable of preventing, improving, or treating a mitochondria-related disease, the method will be widely used for the development of a therapeutic agent for the mitochondria-related disease.
