Abstract: An interposer according to an embodiment of the present invention includes a base layer having opposite first and second surfaces, a wiring structure on the first surface of the base layer, an interposer protective layer disposed on the second surface of the base layer and having a pad recess with a lower surface of the interposer protective layer positioned at a first vertical level and a bottom surface of the pad recess positioned at a second vertical level that is higher than the first vertical level, an interposer pad of which a portion fills the pad recess of the interposer protective layer and the remaining portion protrudes from the interposer protective layer, and an interposer through electrode extending through the base layer and the interposer protective layer to the interposer pad, the interposer through electrode electrically connecting the wiring structure to the interposer pad.

Abstract: The present invention relates to: a composition for wound healing, containing a metal-organic framework (MOF)as an active ingredient; and a wound dressing material comprising a hydrophilic superabsorbent polymer and the MOF, and the composition and the wound dressing material have a wound healing ability, specifically, the excellent effect of healing a wound by promoting fibroblast movement, do not significantly differ from a control group with respect to cytotoxicity, thereby exhibiting excellent safety when applied to a wound site, and have the excellent effect of having a wound recovery rate high enough to be checked with the naked eye over time.

Abstract: A slope controllable foot plate for a golf swing practice apparatus which includes a actuating oil pressure motor providing the power for controlling the slope, a transformation device for transforming the rotating driving power to linear driving power, and a slope control oil pressure cylinder for controlling the slope of the foot plate, whereby a lower height and a simplified structure of the foot plate is obtained.

Abstract: The present invention relates to the slope controllable foot plate for golf swing practice apparatus. The invention is characterized by the actuating oil pressure motor (3, 4) providing the power for controlling the slope, transformation device (5, 8, 9) for transforming rotating driving power to linear driving power, and slope control oil pressure cylinder (11, 12, 13, 14) for controlling the slope of the foot plate. By this constitution, the invention accomplishes the lower height and the simplified structure of the foot plate.
