  • The oxytrichid ticks collected from the cultivated field in Yonchon-gun, Misan-myon Kyonggi-do near Seoul, Korea and the moss-covered soils on the old castle walls in Namhansansons, Kwansiu-gun, Kyonggi-do near Seoul, Korea were Identified as Histriculus cavicola (Kahl, 19351 and H. muscorum Kahl, 1932. These two species were redescribed with illustrations. The description was based on the obsenration of living specimens, protarsol impregnated specimens and biometric analysis. These are reported for the first time from Korea and distinguished from the other congeneric species by the following characteristics: the former has 4 macronuclei, 4 micronuclei, 5 transverse cirri and rather inconspicuous marginal cirri, while the latter, 2 macronuclei, 2 micronuclei, 4 transverse cirri and conspicuous marginal cirri, respecitvely.

  • Dictyostelid cellular slime molds were quantitatively isolated from three golf courses in Kyonggi province. The samples were collected in tee, fairway, rough and out of bounds at each golf courses. Dictyostelium muoroides was found at rough of Seo-Seoul C.C and D. minutum at out of hounds of New Korea C.C Compared with other forests, species diversity and species richness appeared to be low. The properties of soils were investigated in three golf courses. This results were very low in water content, organic matter compared with artificial Korean lawngrsss turf in Seoul National University.

  • The importance of reliability engineering has increased in recent years. Many studies have been carried out into reliability in a variety of research domains, largely focused on industrial engineering, mechanical engineering, electronics engineering, materials engineering and statistical science. However, most of these studies were carried out without collaboration between different areas of study. Here, we analyze research papers and patents regarding reliability that were published during the past five years, and describe core trends in the development of reliability technology from a multidisciplinary perspective.

  • Although many pharmaceutically useful proteins are produced in E. coli expression system, it is very are rare for the system to be used in the production of diagnostic antigen due to a major problem, i.e., false-positive reaction of e. coli host-derived proteins contaminating purified diagnostic antigen with human sera. The N (nucleocapsid) protein of Seoul virus causing haemorrhagic fever with renal syndrome (HFRS) was produced in E. coli BL21 (DE3), and used for the detection of N protein-specific antibodies in human sera. Using the N protein as a diagnostic antigen of HFRS, the false-positive reaction was cleared by merely mixing the test sera with the extract of E. coli host strain not harboring expression plasmid.
