Abstract:
Disclosed is a polyalkylene carbonate and polyolefin-based composite and, more particularly, a composite prepared through reaction of a mixed composition including polyalkylene carbonate, polyolefin, an initiator, and a blending aid, wherein an amount of the polyalkylene carbonate is 60 wt % to 95 wt %, a total amount of the initiator, the blending aid, and the polyolefin is 5 wt % to 40 wt %, and the composite has a matrix-filler morphology in which a matrix formed of the polyalkylene carbonate includes a filler formed of the polyolefin.
Abstract:
Disclosed is a catalyst which can convert ammonia contained in exhaust gas from an engine of a vehicle equipped with a Urea-SCR (Urea-Selective Catalytic Reduction) system, to nitrogen, and a method for preparating the same. The catalyst can convert ammonia which is failed to participate in a conversion reaction of NOx to N2 and slipped out of the SCR catalyst, to nitrogen via a SCO (Selective Catalytic Oxidation) reaction, before the ammonia is released to the air.
Abstract:
Disclosed herein are a method for surface-treating a printed circuit board and a printed circuit board including a surface treatment layer. The method includes: plasma-treating a surface of a printed circuit board; treating the plasma-treated substrate with an organic solderability preserve; performing heat treatment on the substrate treated with the organic solderability preserve; printing a solder paste on the substrate subjected to the heat treatment; reflowing the solder paste printed substrate to fix the solder paste; and deflux washing the resulting substrate.According to the present invention, the discoloration problem due to oxidation of copper can be solved by performing heat treatment under predetermined conditions after treatment with an organic solderability preserve. Therefore, the present invention can meet various multi-reflow processes, as compared with products of the related art.
Abstract:
Disclosed herein are diagnostic markers for lung cancer, isolated from serum glycoproteins. The disclosed diagnostic markers for lung cancer are specifically expressed only in the sera of lung cancer patients at high levels, and thus will be very useful for diagnosing lung cancer and estimating disease progression and treatment.

Abstract:
When a handover apparatus of a user terminal enters a small scale cell within a macrocell area in a state that it is connected to a macrocell, the handover apparatus acquires a delay parameter of the small scale cell and delays handover for a time period of the delay parameter of the small scale cell and determines handover to the small scale cell. Thereby, handover to the small scale cell for a temporal user of the small scale cell can be reduced.
Abstract:
A home appliance is provided. The home appliance includes a main controller for generating a first data signal including status information and a second data signal including operating information, a first sound output device for outputting a first sound signal according to the first data signal including status information to be transmitted through a communication network, and a second sound output device for outputting a second sound signal according to the second data signal including operating information to be perceived by a user. Thus, the sound signal regarding the status information and the sound signal regarding the operating information can be output through the different sound output devices, i.e., the first and second sound output devices.
