  Open clusters are useful tools to investigate the structure and evolution of
the Galactic disk. We have started a long-term project to obtain UBVI CCD
Photometry of open clusters which were little studied before, using the Doyak
1.8 m telescope of Bohyunsan Optical Astronomy Observatory in Korea. The
primary goals of this project are (1) to make a catalog of UBVI photometry of
open clusters, (2) to make an atlas of open clusters, and (3) to survey and
monitor variable stars in open clusters. Here we describe this project and
report the first results based on preliminary analysis of the data on four open
clusters in the survey sample: Be 14, Cr 74, Biu 9, and NGC 2355. Isochrone
fitting of the color-magnitude diagrams of the clusters shows that all of them
are intermediate age to old (0.3 - 1.6 Gyrs) open clusters with moderate
metallicity.
