摘要:
The present invention relates, generally, to methods for joining an electronic part finished with nickel and an electronic part finished with electroless nickel, which can prevent a brittle fracture, more particularly, to a method for joining an electronic part finished with nickel and an electronic part finished with electroless nickel with a solder by controlling the composition of the solder to prevent a brittle fracture occurring at the solder joining portion.A method for joining an electronic part finished with nickel and an electronic part finished with electroless nickel, comprising: (1) reflowing solder to a nickel portion of an electronic part finished with nickel to obtain an electronic part where an intermetallic compound and a solder are formed; (2) obtaining an electronic part finished with an eletroless nickel, of which the nickel portion is connected with the solder; and (3) solder-joining an electronic part finished with nickel obtained in the step (1) and the electronic part finished with electroless nickel obtained in the step (2).

Provided is a pharmaceutical composition for the treatment and prevention of alcoholic liver diseases, including cilostazol as an active ingredient. Cilostazol inhibits expression levels of TNF-α and FAS (fatty acid synthase) gene in a concentration-dependent manner, and also significantly inhibits the activity of caspase-3. Accordingly, cilostazol shows superior effects for the treatment or prevention of alcoholic liver diseases, in particular, alcoholic hepatitis compared to pentoxifylline which is conventionally used as a therapeutic agent for the treatment for alcoholic hepatitis. Thus, cilostazol is suitable for use as a drug for the treatment or prevention of alcoholic hepatitis.

Three-dimensional semiconductor devices may be provided. The devices may include a stack-structure including gate patterns and an insulation pattern. The stack-structure may further include a first portion and a second portion, and the second portion of the stack-structure may have a narrower width than the first portion. The devices may also include an active pattern that penetrates the stack-structure. The devices may further include a common source region adjacent the stack-structure. The devices may additionally include a strapping contact plug on the common source region.
