Abstract: The present invention relates to a composition for preventing or treating a bone disease, obesity or an obesity-mediated metabolic disease, cancer, or cancer metastasis, and a method of screening a drug for treating the diseases, which includes an inhibitor of transmembrane 4 L six family member 19 (TM4SF19) expression or activity.

Abstract: A semiconductor device includes a first interlayer insulating film disposed on a substrate and having a first trench. A first lower conductive pattern fills the first trench and includes first and second valley areas that are spaced apart from each other in a first direction parallel to an upper surface of the substrate. The first and second valley areas are recessed toward the substrate. A second interlayer insulating film is disposed on the first interlayer insulating film and includes a second trench that exposes at least a portion of the first lower conductive pattern. An upper conductive pattern fills the second trench and includes an upper barrier film and an upper filling film disposed on the upper barrier film. The upper conductive pattern at least partially fills the first valley area.

Abstract: Disclosed herein are an aluminum alloy for an insert ring, an aluminum insert ring using the same, and a piston manufacturing method using the same, and, particularly, are an insert ring manufactured to have high strength and abrasion resistance and reduce its weight by adjusting aluminum alloy components, and a method of manufacturing a piston having high bonding properties to the insert ring through the same.

Abstract: An aluminum alloy is provided that includes magnesium (Mg) of about 8.0 wt % to 10.5 wt %, silicon (Si) of about 1.9 wt % to 3.4 wt %, copper (Cu) of about 0.4 wt % to 2.0 wt %, and a balance of Al. In addition, a vehicle part is manufactured using the same aluminum alloy.
