Abstract: The present invention relates to a compound showing an excellent agonistic activity for a melanocortin receptor and, more specifically, to the compound of chemical formula 1, a pharmaceutical composition containing same as an active ingredient, and a use thereof. In detail, the compound of the present invention exhibits an excellent agonistic activity for melanocortin-4 receptor and thus, can be advantageously used especially for preventing or treating obesity, diabetes, inflammation, and impotence.

Abstract: A semiconductor package is provided. The semiconductor package includes a semiconductor chip including an integrated circuit (IC) pad configured to output a wireless frequency signal, a lead frame including a package pad configured to receive the wireless frequency signal, a first wire of which one end is connected to the IC pad, a second wire of which one end is connected to the package pad, and a circuit element connected to the first wire and the second wire in parallel or in series. A radio frequency (RF) output impedance of the package pad or an RF output impedance of the IC pad is controlled by a type of the circuit element or a connection relationship between the circuit element, the first wire, and the second wire.

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: Disclosed herein is an assembly-type ornament. The assembly-type ornament includes: a male body placed on an outer surface of a coupling object having a mounting hole formed therethrough and including an insert protruding from one surface thereof to be inserted into the mounting hole and a locking groove formed along an outer circumferential surface of the insert; and a female body placed inside the coupling object and including a holder protruding from one surface thereof and formed with an insertion hole receiving the insert and a locking protrusion formed on an inner circumferential surface of the holder to be engaged with the locking groove.

Abstract: A mold adjustment device of an injection molding machine is required for movement of a rear template that moves depending on a size of a mold in a toggle clamp of the injection molding machine. At this time, a spherical bearing and/or a bushing is attached to an outer circumference of a nut of a tie bar gear that rotates along a tie bar and a tie bar screw enduring a clamping force of the toggle clamp so as to be contacted with the rear template. This mold adjustment device clears up any factor generating vibration or noise during the injection molding, thereby remarkably decreasing stoppage generated during the mold adjustment process and also relatively reducing vibration and noise.
