Preliminary time-series observations for short-period variability survey (SPVS) were carried out using a 155mm refractor and a 2k×3k CCD camera at Bohyunsan Optical Astronomy Observatory. We found 21 new variable stars in the 90′×60′ test field region : 9 eclipsing binary stars, 5δ Scuti type stars, a γ Doradus type star, and 6 long period variables. The observing field center is R.A. 05 h00m00s, DEC. 50∘00′00" (J2000.0). The period and amplitude ranges for the short-period variables, i.e., δ Scuti stars, were 0.052day - 0.107day and 0.012mag - 0.064mag, respectively.
