Disclosed are new compounds of formula exhibiting excellent activity for glucokinase, pharmaceutical compositions having the same as an active ingredient, and a method of using the same as an active ingredient for lowering blood glucose level:in which the substituents are as defined herein. The third metal line is electrically linked to one of the adjacent metal lines and is designed to project into the space between the adjacent metal lines, thereby elevating parasitic capacitance while reducing the range of variation of parasitic capacitance over a known range of critical dimensions. Potential linking errors are then identified within the sample data set. In this inputoutput line configuration, the greater the number of word lines W that are selected, the greater the number of bits that can be output. The method for the continuous key operation of the mobile terminal provides convenience to a user who uses a directional key service through an optical mouse and a touchscreen. The insulating layer reduces the heat transference from the environs to the interior chamber region.
