Abstract: The present invention relates to novel mesylate salt of N-(5-(4-(4-((dimethylamino)methyl)-3-phenyl-1H-pyrazol-1-yl)pyrimidine-2-ylamino)-4-methoxy-2-morpholinophenyl)acrylamide, a novel crystalline form thereof, and a process for preparing the same. More specifically, the present invention relates to mesylate salt of N-(5-(4-(4-((dimethylamino)methyl)-3-phenyl-1H-pyrazol-1-yl)pyrimidine-2-ylamino)-4-methoxy-2-morpholinophenyl)acrylamide, which is excellent in stability, solubility, and bioavailability when it is administered not only alone but also in combination with other drugs and which has a high purity, a crystalline form thereof, and a process for preparing the same.

Abstract: The present invention relates to a method for preparing a polyolefin block copolymer, the method comprising: a first step of coordination polymerization of an olefin monomer with a transition metal catalyst in the presence of organozinc; and a second step of continuously adding a diacyl peroxide compound to perform polymerization, and to a polyolefin block copolymer prepared therefrom.

Abstract: Embodiments of the present invention provide an accelerated lifetime estimation device for predicting the lifetime of a secondary battery, and a method thereof. The accelerated lifetime estimation device can accurately estimate a normal lifetime of the secondary battery while reducing an evaluation time period of the secondary battery.

Abstract: A water-cooling type cooler and an inverter employing the same are disclosed. A guide pin for distributing cooling water is formed in the middle of a cooling water flow path having a bent face, to make a flow rate of cooling water at the bent portion of the cooling water flow path uniform to thus improve cooling performance of the water-cooling type cooler. In addition, because the cooling performance of the water-cooling type cooler is improved without extending the cooling pin, an increase in the weight of the water-cooling type cooler can be reduced and a fabrication cost of the water-cooling type cooler can be reduced.

Abstract: Provided is an arm support of a bicycle which is configured to reduce an intensive pressure acting from a seat due to the rider's weight inclined at the seat by spreading the inclined weight to other parts. The rider can get on or off the bicycle more easily by putting his/her arms on the arm support. In the bicycle including a frame, a seat disposed at the frame, a handle for controlling the direction of the bicycle, and wheels rotatably coupled to the frame, the arm support includes: a support shaft including a coupling part fixed to the frame: a support bar disposed at an upper side of the support shaft and connected to both sides of the support shaft; and armrests coupled to the support bar so that a rider puts his/her arms thereon The armrests extend horizontally from the vertical support bars and bent toward the seat or upward to form armrest channels.
