With this experiment we have conclusion as follows. $\cdot$ Total FCR-9501 are 8 units. $\cdot$ All hospitals under study are conducting the high kvp radiographing with 115-120kvp and 4$\sim$10mAs. $\cdot$ The mean value of the chest exposure was 0.524$\sim$0.301mGy. $\cdot$ The percentage of the absorber finding from phantom was more the 85% with a range of 100$\sim$136 kvp. $\cdot$ The mean dose from phantom was 0.990mGy with 124 kvp and 16 mAs. $\cdot$ There is no difference in the amount of information due to the change of kvp and mAs, but some coarseness of images can be seen in the magnified images. $\cdot$ The resolving power was about 1.5/mm. $\cdot$ The increase and decrease of 10$\sim$30 kvp from common kvp has not influenced on the amount of information. $\cdot$ The exposure could be reduced by 0.170$\sim$0.570mGy.

We tried to find any factor to reduce the exposure dose with ST-VA type generator which has the higher exposure dose. The guideline recommended by the provisions of IAEA regulation is being used at the time of radiation exposure and almost of those equipments used for this study had less amount of doses than those in the guideline. The FCR may be possible to decrease a certain amount of dose with effective applications of it's automatic image compensation utilities and the verifying function in PACS. Next time, it is required to add a great number of hospitals for wide range of studios and measurements, and make standard exposure Control table which will bing in practice, material decrease of dose volumes when radiation exposure.
Flusilazole의 훈증 효과에 의한 양파검은곰팡이병균(Aspergillus niger)의 포자 형성 억제

1998년 전남 신안군의 양파 상온 저장고에서 발생한 검은색의 곰팡이는 검은곰팡이병을 일으키는 Aspergillusniger로 동정되었다. A. niger AnYD-1은 3$0^{\circ}C$에서 균사생장, 포자발아 그리고 양파에 대한 병원성이 가장 양호하였다. PDA 배지 상에서 실시한 in vitro의 실험에서 flusilazole과 hexaconazole은 A. niger AnYD-1의 균사 생장 억제 효과는 적었지만, 병원균에 살균제를 직접 처리하지 않고 증기 상태로 처리하였을 때 포자의 형성을 강하게 억제하는 특이적 인 훈증효과를 보였다. Flusilazole과 hexaconazole의 훈증의 효과는 사용하는 용매, 처리 농도와 배양 온도에 따라서 차이가 있었다. Dimethylsulfoxide와 dimethylformamide를 용매로 사용하였을 때 가장 높은 효과가 나타났으며, 고온에서 배양할수록 포자형성 억제 효과가 크게 나타났다. In 1998, a pathogen isolated from infected onions was identified as Aspergillus niger. At 3$0^{\circ}C$, A. niger AnYD-1 showed the best mycelial growth, spore germination, and high pathogenicity to onions. In spite of the weak inhibitory effect of flusilazole and hexaconazole on the mycelial growth on PDA, they showed the specific inhibitory activity against the formation of spores in the vapour phase. With flusilazole and hexaconazole, the effects of the solvent, the applied concentration and the incubating temperature on the activities inhibiting the spore formation were confirmed. Their inhibitory effect on the spore formation in vapour phase was excellent by solving them with dimethylsulfoxide and dimethylformamide among tested solvents, and applying them at high temperature such as 30~35$^{\circ}C$.
