Abstract: The present disclosure relates to an antenna element including: a dielectric layer; a radiation electrode arranged on an upper surface of the dielectric layer and including a first mesh structure; and a dummy electrode arranged on the upper surface of the dielectric layer and including a second mesh structure, in which at least one of the radiation electrode and the dummy electrode satisfies Equation 1, and an image display device including the same.

Abstract: The present invention relates to a novel peptide capable of inhibiting TGF-? signaling and the use thereof. The peptide of the present invention is capable of inhibiting the TGF-?-induced signaling pathway or the expression of TGF-?, and thus can treat or prevent various diseases caused by TGF-? signaling, and furthermore, can effectively inhibit tumorigenesis processes such as TGF-?-signaling induced tumor growth and metastasis.

Abstract: The present invention provides a wave-shaped grouting bulb (100) for securing an underground bearing capacity of a steel bar (10), the bulb comprising a plurality of protrusions (120), which have a predetermined maximum diameter (D1) and are formed along the longitudinal direction of a cylindrical pillar part (110) extending downward, wherein the neighboring protrusions (120) are formed to be spaced from each other by a predetermined formation distance (s). The present invention has an advantageous effect of improving a skin friction force and resistance to compression and pullout in the grouting bulb integrated with the steel bar and thus enhancing structural stability in the micropile body.

Abstract: An aliphatic polycarbonate is disclosed in which a salt consisting of a metal or onium cation and an anion having a pKa not greater than 3 is dispersed. The aliphatic polycarbonate includes repeating units of Formula 1: [-A-OC(O)O-] (wherein A is a substituted or unsubstituted C3-C60 alkylene, or a substituted or unsubstituted C3-C60 heteroalkylene and the O-A-O units in one polymer chain may be identical to or different from each other).
