Abstract: A log analysis system and method for a security system, which allow the security system monitoring communications between general systems to generate logs according to a predetermined rule and store the same in a log database are disclosed. A log analyzer determines whether log information containing attack content in the log database exists, and if log information containing attack content exists, sorts the log information by attack name. The log analyzer determines whether the attack content data of the log information sorted by attack name is based on a web request or not, and if the attack content data is based on a web request, performs HTTP-indicator-based text normalization. The log analyzer performs rule-pattern-based text normalization after the HTTP-indicator-based text normalization.

Abstract: A primary shift portion has a first predetermined speed ratio at a first shift-speed, a second predetermined speed ratio at a second shift-speed, a speed ratio of “1” at third and fifth shift-speeds, and a third predetermined speed ratio at fourth and sixth shift-speeds. A secondary shift portion has a predetermined reduction speed ratio at first, second, third, and fourth shift-speeds, and a speed ratio of “1” at fifth and sixth shift-speeds. The method realizes a 6-speed automatic transmission being capable of sequentially up- and down-shifting and a plurality of skip shifts with an existing 5-speed automatic transmission.

Abstract: A clutch assembly of an automatic transmission includes a clutch pack mounted on a turbine shaft, a piston mounted to one end of the clutch pack for selectively depressing the clutch pack, a stopper plate fixed at the other end of the clutch pack for supporting the clutch pack, and a plurality of return springs arranged parallel with the clutch pack between the stopper plate and the piston, for returning the piston.
