여러가지 초증감 처리법 중에서 굽기(baking), 쐬기(soaking)과 진공처리(evacuation)를 할 수 있는 초증감처리장치를 설계 제작하고 초증감 처리 결과 시험에 이용되는 표준감광기 (sensitometer)와 농도쐐기 (step wedge)를 제작하였다. 이를 천체사진용 건판인 103a-O와 IIIa-J에 시험적으로 사용하여 감도와 신호대 잡음비의 증가를 확인하였다.

This study was attempted to simplify the complex steeping mechanism and propose the scientific approach of microorganism. As Enzyme activity showed that as steeping hours increase, the а-amylase activity increased. Most commonly microorganisms in steeping liquid were Corynebacter spp., Candida spp. and Lactobacillus spp. According to results, steeping acidifies the character of glutinous rice, affec-ting the starch's n-amylase and bring about component's changes. As Candide spp. and Lactobaillus spp. of the steeping liquid increase, the character of liquid is acidifying.

최근 근권의 산소부족 문제를 근본적으로 해결할 수 있는 수경능법으로서 분무경에 관한 관심은 매우 높으며 분무경의 우수성이 실증적으로 제시되고 있으나 분무경의 경우 고압을 필요로 하므로 장치가 복잡해지거나 엽체류의 경우 분무노즐과의 거리에 따라 생장이 균일하지 않는 문제점을 갖고 있으므로 분무경과 같이 근권산소 문제를 근본적으로 해결하는 효과를 가지면서도 취급 및 관리가 편리한 수경시스템의 개발이 절실히 요구되고 있다. (중략)

The stability of hydrogenated amorphous silicon (a-Si:H) films under the light soaking are very important since the applications of a-Si:H films are solar cells, color sensors, photosensors, and thin film transistors(TFTs). We found the changes of the electric conductivity and the conductivity activation energy (Ea) of a-Si:H films by argon radical annealing. The deposition rate of a-Si:H films depends on the argon radical annealing time. The optical band gap and the hydrogen contents in the a-Si:H films are changes along the argon radical annealing time. We will discuss the microscopic processes of argon radical annealing in a-si:H films.

Anthracnose of peanut (Arachis hypogaea L.) was found in the peanut cultivating fields in Iksan, Korea in September 1997. Infected plants showed irregularly circular water soaking brown lesions. In the severe case, leaves and stems were entirely died. The causal fungus of anthracnose isolated from the diseased plants was identified as Colletotrichum gloeosporioides Penz. and its teleomorph was Glomerella cingulata (Stonem.) Spauld. & Sch. according to the criteria based on the cultural and morphological characteristics. By arificial inoculation with fungal spores on healthy peanut, anthracnose symptom was observed 15 days after inoculation.

It has been that, above $600^{\circ}C$, a cover crystal is essential for protecting InP substrate from severe gas etching during soaking procedure and shown that the melt back rate of substrate crystal in In solvent is about 0.90${\mu}{\textrm}{m}$/sec at 635$^{\circ}C$, 0.57${\mu}{\textrm}{m}$/sec at 615$^{\circ}C$ and 0.37${\mu}{\textrm}{m}$/sec at 595$^{\circ}C$.
