Abstract: The present specification relates to a composition for preventing, alleviating or treating burnout syndrome, containing a natural extract as an active ingredient. According to one aspect of the present invention, the composition contains a ginseng fruit extract, and thus is useful for preventing, treating and alleviating burnout syndrome. In addition, according to one aspect of the present invention, the composition further contains ginseng fruit and one or more selected from the group consisting of red ginseng, Angelica gigas, Cornus officinalis, Cervi parvum corni, and Nigella sativa, so as to maximize the synergistic effect among two or more ingredients, thereby exhibiting excellent effects on the prevention, treatment and alleviation of burnout syndrome. Therefore, there is an advantage of making individuals and society mentally and physically healthy since burnout syndrome can be prevented, treated and alleviated, by using the composition of the present invention.

Abstract: A semiconductor device and a method of fabricating the same are provided. According to the present invention, a semiconductor device comprises an active region formed in a substrate, and including flat surfaces and hole-shaped recess portions; upper-level plugs disposed over the flat surfaces; a spacer disposed between the upper-level plugs and providing a trench exposing the hole-shaped recess portions; a lower-level plug filling the hole-shaped recess portions; and a buried conductive line disposed over the lower-level plug and partially filling the trench.

Abstract: Disclosed are a method and apparatus for reusing wastewater. The method for reusing wastewater disclosed herein includes: generating a mixed wastewater by mixing multiple types of wastewater (S20); performing a first purification by passing the mixed wastewater through a flocculation-sedimentation unit (S40); performing a second purification by passing an effluent of the flocculation-sedimentation unit through a membrane bioreactor (MBR) (S60); performing a third purification by passing an effluent of the MBR through a reverse-osmosis membrane unit (S80); and reusing an effluent of the reverse-osmosis membrane unit as cooling water or industrial water (S100).

Abstract: A silicon-carbon complex comprising carbon-based particles and silicon-based particles, wherein the silicon-based particles are dispersed and positioned on surfaces of the carbon-based particles, the carbon-based particles have a specific surface area of 0.4 m2/g to 1.5 m2/g, and the silicon-based particles are doped with one or more elements selected from the group consisting of Mg, Li, Ca, and Al, and a negative electrode active material for lithium secondary battery comprising the same.

Abstract: The present invention relates to a heteroaryl derivative compound and a use thereof. Since the heteroaryl derivative of the present invention exhibits excellent inhibitory activity against EGFR, the heteroaryl derivative can be usefully used as a therapeutic agent for EGFR-associated diseases.

Abstract: Provided is an apparatus for measuring a wafer. The apparatus may include a chuck disposed on a stage and a plate connected with the stage, a horizontal frame configured to support a wafer, and a vertical frame connecting the plate and the horizontal frame. The apparatus may further include first to third adsorption portions connected with the horizontal frame and configured to adsorb the wafer, a support bar penetrating through the chuck and extending in a first direction and a beam irradiator connected to the support bar and disposed between the plate and the horizontal frame. The beam irradiator may be configured to irradiate a beam on the wafer. The apparatus may further include a detector on an opposite side of the horizontal frame from the beam irradiator and configured to receive the beam after it has penetrated through the wafer.
