High quality $YBa_2Cu_3O_y$(YBCO) thin films for directly coupled dc superconducting quantum interference device (SQUID) were fabricated by pulsed laser deposition. Several critical parameters have been optimized through systematic studies. Thus, the films showing the $T_c$ of above 91K and $J_c$ of above$2\times10^6A/cm^2$ at 77K were routinely obtained. Extensive AFM and X-ray diffraction studies have been conducted for morphological and structural analyses. The directly coupled DC-SQUIDs were fabricated from the YBCO thin films deposited on $SrTiO_3$ bicrystals under the optimized conditions. The measurement on $2I_c$ and swing voltage give 200$\mu$A and 17$\mu$V at 77K, respectively.

Thirty three entomopathogenic species belonging to twelve genus were collected throughout 16 collecting sites from 1990 to 1996. Among those collected species, 14 unrecorded species such as Cordyceps bifusispora, C. martialis, C. oxycephala, C. paludosa, C. pentatomi, C. rosea, C. ryogamiensis, Shimizuomyces paradoxa, Akanthomyces aculeatus, Polycephalomyces ramosus, Tilachlidiopsis nigra were added to Korean entomopathogenic species through this study. In nature, occurrence of Cordyceps nutans, C. sphecocephala and Paecilomyces tenuipes were from early June to late September. On the other hand, C. militaris, C. kyushuensis and C. pruinosa were mainly found from mid July to mid August when relative humidity are increased. Nine species of the genus Cordyceps including C. bifusispora and four deuteromycetous species were isolated. As a result of cultural test using six Cordyceps species, anamorph of C. militaris, C. kyushuensis were proved as Verticillium sp. C. pruinosa as Acremonium sp., C. sphecocephala as Hymenostilbe sp. and C. scarabaeicola as Beauveria sp., respectively.
