Abstract: Disclosed herein is a catalyst for an upgrading reaction of biomass pyrolysis oil, a method for preparing the same, and a method for upgrading biomass pyrolysis oil using the same. The catalyst is a composite inorganic oxide, and the composite inorganic oxide includes lanthanum, nickel, titanium, and cerium. When a metal catalyst supported on carbon is used as a catalyst for a first step reaction, by using the catalyst as a catalyst for a second step reaction, the efficiency of the upgrading reaction of bio-oil is increased and a continuous reaction is possible without clogging of a continuous reactor.

Abstract: A power module for a vehicle, includes: a lower substrate and an upper substrate spaced from the lower substrate; a semiconductor chip disposed between the lower substrate and the upper substrate; a first power lead disposed being spaced from the semiconductor chip and connected to one of the lower substrate and the upper substrate; and a second power lead disposed being spaced from the semiconductor chip and connected to both the lower substrate and the upper substrate.

Abstract: A slipper that is an assemblable slipper is proposed. The slipper is assembled without use of an adhesive, used with any design as desired by the user, and is easy to carry. The slipper can be assembled, without use of an adhesive by inserting a band into a sole portion and fixing the band with a bed. In effect, when the slipper is carried or is not in use, a space for carrying can be reduced by separating the band from the sole portion, and it is also easy to react to damage or separation of the band. In addition, as it is easy to replace the band, the slipper can be easily replaced with a design as desired by the user. In this regard, the present invention is effective in extending the life of the slipper as a result of replacement of the band.

Abstract: Disclosed is an article of footwear with a new insole board and insole construction, including an insole having a protrusion at a forefoot area, and a protrusion at a heel area. The protrusions respectively go through two holes of the insole board and are respectively inserted into an outsole recession area or a midsole recession area which are called a forefoot chamber and a heel chamber, and the two holes take up more than a specific percentage of the forefoot and heel area.
