A number of bifidobacterial species of human origin were screened for the presence of cryptic plasmids. One strain, Bifidobacterium longum FI10564, harbored plasmids of approximately 2.2 kb, 3.6 kb, and 4.9 kb in size. The smallest plasmid, pFI2576(2,197 bp), was studied in detail and its complete nucleotide sequence was determined. Computer-assisted analysis of this novel plasmid(G+C content 62%) identified 9 putative open reading frames(orfs), 3 of which were shown to be probable genes. These putative genes are arranged in an operon-like structure, in which the overlapping orfs 1 and 2 encode putative Rep proteins and are highly homologous to the rep genes of the B. longum plasmid pMBI(1,847 bp). The mechanism of replication of pFI2576 was investigated using Southern blot analysis of whole cell lysates, with and without S1 nuclease treatment, and atomic force microscopy(AFM). The results indicate that pFI2576 is likely to use the theta mode of replication.

A hybrid dust-collector combining electrostatic charging with fabric filtration method was developed, and its performance characteristics were evaluated in this study. Charged particles build porous dendritic structure on the surfaces of filter by electrostatic attraction, increasing the collection efficiency of dust particles and reducing the pressure drop through the deposited dust layer and filter media. The cleaning performance of the dust layer is improved because the dendritic structured dust layer can be removed more easily by pulse jet cleaning flow. The results of the experiment showed a reduction of fine particle emission of 37% and the energy saving of 13% by precharging dust particles before filtration.

This research was conducted to investigate the influences caused by solifluction soil on the physicochemistry of stream water quality in the riparian area: four points of the northeastern side slopes part of the Bughansan National Park from March to May of 2002. The average pH of stream water was relatively high with the influenced of solifluction soil. The average electrical conductivity of upstream water was 2.1${\sim}$2.8 times lower than that in downstream water. pH and amount of anion ($Cl^-,\;N0_3\;^-, So_4\;^{2-}$) of stream water was correlated under the effect of solifluction soil.

This study focused on 15 parks to investigate the actual developmental conditions for preservation type parks and artificial type parks in the 9 residential land development sites managed by the Korea Land Corporation in Daegu and Gyeongsangbukdo area from 1994 to 2002. Emphasis is placed upon the types of land use, park arrangements, park facilities, types of planted trees and landscaping expense, with a view to discovering ways of improving the efficiency of future park development.
