Outline of Final Research Achievements

We have performed an all-sky survey for infrared clusters using the 2 Micron All Sky Survey (2MASS) point source catalog. We detected 576 clusters, and recorded their coordinates, extents, and numbers of the constituent stars. In addition, we carried out molecular observations toward some of the natal clumps, and we detected infalling motion with rotation of the clump associated with the S235AB cluster.
