Total 60 strains were isolated from various sources such as soils, composte, and rottenwood, debris using cellulase screen media from the isolated 60 strains in the first experiments 8 strains were first selected text as good ones and identified, cellulase activities were tested The results of these studies are as follows; 1.Identified of 8 strains SK -17 ; SO-2, SW-1 ; Trichoderma viride ST-1 ; Penicillium sp. SO-9 ; Aspergillus oryzae SW-2 ; Aspergillus niger SO-5 ; Aspergillus ochraceus SBN ; Neuropora sp. 2.The strongest of celluase activity is SW-2, SBN and SO-9. The Mark SBN is the strongest in Carboxy Methyl Cellulose liquefaction and SO-9 is higher activities in cup method reaction. 3.In the test of the 1'eaction time of substrate and enzyme. The enzyme activities are high as prorata of reaction time of 24hr, CMC liquefaction become a half of total substrate. 4.According to cultural periods, enzyme activity is reahced the hight one in the 4 or 5 days cultural time airier the 5 days cultural time period enzyme activities was dwindled. 5.At the volume of CMC liquefaction is much, the index of refraction is high by method of diffrential refractometer. 6.In the teat of variation pH of substrate, good results come out at pH 4.6-5.0 of substrate. The optimum temperature was 45-50℃.

This paper propose the design and implementation of interpolation filter which interpolate subsampled data with the FPGA in HD-MAC decoder. Interpolation filter is FMH(FIR-Medain Hybrid) filter, hybrid filter composed of linear and nonliner filter, which has characteristics of good conservation of edge and good restoration of fine lines and robust to noise. Interpolator is implemented with FPGA of Actel company. It is proved that interpolator is well operated at 27MHz.

申炳湜 國立昌原大學校 基礎科學硏究所 1992 基礎科學硏究所論文集 Vol.3 No.-
The concentration and composition of fatty acids were measrued in homogenates of chestnut weevil, Cu-rculio dentipes Roelofs according to development stages. During all stages, a total number of 7 Fatty acids were identified such as Lauric acid, Myristic acid, Pal-mitic acid, Stearic acid, Oleic acid, Linoleic acid, and Linolenic acid. . The maximin amount of fatty accids were found at non overwintering larva and dramatically declined at wintering larva. The higest content of oleic acid was showns during all stages.

Escherichia coli 형질전환체가 생산하는 Zymomonas mobilis 알콜 탈수소 효소의 분석
신병식,윤기홍,박무영 한국미생물 · 생명공학회 1990 한국미생물·생명공학회지 Vol.18 No.3
Zymomonas mobilis의 알코올 탈수소 효소 유전자가 클로닝된 대장균 형질전환체의 세포 추출물로부터 알코올 탈수소 효소를 분리정제하였다. 형질전환된 Escherichia coli(pADS93)가 생산하는 Z.mobilis 유전자 유래의 알코올 탈수소 효소는 분자량이 40,000인 동일한 4개의 subunits로 구성된 tetramer임이 밝혀졌으며 이것은 Z.mobilis의 세포 추출물로부터 분리한 알코올 탈수소 효소와 동일하였다. 이 효소의 정반응(ethanol 산화)은 pH의 영향을 많이 받으며 pH는 10.0이었고 역반응(acetaldehyde 환원)에서는 최적의 pH가 7.5-8.5 이었지만 pH에 따라 크게 영향을 받지는 않았다. The structural gene (zadhII) encoding an alcohol dehydrogenase II from Zyrnornonas mobilis was cloned into Escherichia coli in our laboratory (Yoon et al., 1989. Kor. J. Microbiol. Biotechnol.). From E. coli (pADS93) carrying the zadhII gene, the Z mobilis alcochol dehydrogenase II (ZADH-II) was purified by sonication, $(NH_4)_2SO_4$, fractionation, and chromatography. The ZADH-I1 enzyme produced by Z. mobilis cell was also purified to compare to the enzyme produced by E. coli (pADS93). The purified enzyme from cell extract of E. coli (pADS93) was identified to be a tetramer being composed of four identical subunits having molecular weight of 40, 000 dalton like that of Z. mobilis. The pH optimum for the reaction oxidizing ethanol to acetaldehyde was 10.0 while the optimum for the reverse reaction was 7.5-8.5. The apparent $K_m$ values for ethanol and NAD + were $1.2 \times 10^{-1}M$and $5.1\times 10^{-5}M$, respectively. In addition, it was found that the $K_m$ value for acetaldehyde was very lower than that for ethanol.

無燃炭 燃燒에 關한 硏究 (第 1 報). 一酸化炭素 燃燒反應 및 燃燒裝置
신병식,신세건,Shin Byoung Sik,Shin Sei Kun 대한화학회 1975 대한화학회지 Vol.19 No.3
燃炭을 燃燒시킬 때 흙통중에서 一定量의 煉炭을 一定時間 燃燒를 持續시키기 위하여 空氣의 供給을 制限하게 되므로 많은 量의 一酸化炭素가 發生한다. 그러므로 一酸化炭素의 發生을 抑制하는 基本實驗으로 窒素, 酸素 및 一酸化炭素의 混合가스 및 炭素의 存在下에서 一酸化炭素의 燃燒率을 測定한 結果 一酸化炭素 燃燒溫度는 $700^{\circ}C$以上이고 空氣의 供給이 增加 할수록 一酸化炭素의 燃燒率이 改善됨을 알았다. 이러한 事實에서 燃燒時間의 延長과 一酸化炭素의 發生 抑制는 서로 相反되므로 두 가지 條件을 滿足시키는, 보다 效果的 燃燒裝置를 考案하였다. 즉 內徑이 다른 二重鐵筒으로 暖爐를 만들어 若干의 二次空氣가 에어자켓 下部에서 들어가 上部의 작은 구멍에서 나오게끔 하면 燃燒中인 煉炭과 熱交換되어 燃燒雰圍氣의 溫度는 低下된다. 따라서 燃燒時間은 길어지면 또 二重鐵筒을 通하여 上昇하는 豫熱空氣는 一酸化炭素의 再演燒를 促進시키게 되므로 一酸化炭素의 發生量은 흙통을 使用하였을때 보다도 1/20 程度로 減少된다. In the course of anthracite briquet combustion, air draft is usually controlled to continue burning of definite amount of briquet in the conventional hollow clay cylinder with air inlet hole open for given time, so that a large amount of CO tends to be produced. Therefore, it is necessary to establish an improved combustion process to depress the yielding rate of CO and for this purpose, we performed a basic experiment in which combustion rate of CO was measured in the mixture of $N_2, O_2 $and CO gas with or without the presence charcoal at the various temperature. The observed results showed that the burning temperature of CO is about 680${\sim}700^{\circ}C$, further burning rate of it was increased with increasing the amount of draft. From these facts, longer combustion time and low CO generation are thus contradictory to each other and it has been long desired to make those two compatible somehow. The purpose of the present investigation lies in designing an effective new briquet stove to meet the above requirements. The essential feature of the new briquet stove consisted in the use of two hollow iron cylinders with different inside diameter. A cylindrical air jacket thus formed served as a path through which small amount of secondary air run from the bottom of the stove to the upper vent holes. Heat exchange occurred between the upgoing secondary air and the burning briquet, which lowered the combustion temperature of the briquet. The results observed were selfevident as anticipated. It was confirmed that the combustion time was increased tolerably due to the heat loss from the combustion zone and that CO in the flue gas was reoxidized at the upper portion of the stove by the upgoing hot secondary air. By this reoxidation reaction the concentration of CO in the flue gas was found to be about 1/20 of that in case the conventional clay cylinder was used as briquet jacket.
