국내 원예시설이 고정화되면서 각종 연작 장해가 나타남에 따라 객토와 토양소독의 필요성이 커지고 있으나 객토와 토양소독에 소요되는 비용 증가가 큰 문제로 대두되고 있다. 이에 따른 간이한 양액재배 시스템으로서 농가에서도 투자비용과 운용비용이 저렴하면서 환경오염의 염려가 없거나 적은 각종 인공배지를 활용한 토마토 자루재배(bag culture) 실험결과는 다음과 같다. 1. 단용배지를 이용한 토마토 자루배재에서 질석, 훈탄, 모래, 페놀수지 (PRE), 입상면, perlite 등에서 생육, 수량 및 품질면에서 이용가능성이 높고 이들 배지의 단점을 보완한다면 암면 대체도 가능할 것으로 보인다. 2. 혼합배지를 이용한 토마토 자루재배에서 perlite와 입상면 혼합처리에서는 perlite 20-40％수준과 입상면 80-60％수준에서, peatmoss와 질석 혼합처리에서는 peatmoss 40-60％와, 질석 60-40％ 혼합비율에서, peatmoss+질석 +입 상면 혼합처리에서는 peatmoss를 50-60％로 하고 질석과 입상면을 각각 25-20％로 혼합한 경우에서 각각 높은 수량과 품질을 보여주었다.

A study is to predict the effective pulsing distance following to the pulsing pressure, nozzle diameter, filtration velocity using numercial analysis techniques and use it as an efficient operation condition and economic data for on-line type pulse air jet bag filter. Filtration area 6 m² condition, calculate filter resistance coefficient for simulation through the primary experiments using coke dust. For CFD simulation, analysis pulsing characteristics about nozzle diameter, filtration velocity and pulsing pressure. The maximum pulsing length of on-line type pulse air jet bag filter, in 10mm nozzle, filtration velocity 1.5m/min and pulsing pressure 5 bar conditions, is 2,285 mm, maximum length is 76.2% of the total filter bag, which is sufficient to pulsing. In 12mm nozzle, pulsing pressure 5 bar and filtration area 1.22 m² conditions, the maximum pulsing length of on-line type pulse air jet bag filter is 1,744~2,952 mm, and the maximum length is 2,952 mm indicates pulsing air can be reached to the bottom of filter bag. When the nozzle diameter is increased 8mm to 10mm, maximum pulsing length is extended 40~47%, and increased 10mm to 12 mm, maximum pulsing length is extended 10~17%. For effective pulsing, over the 5bar of pulsing pressure and larger than 10 mm of nozzle diameter are required.

Drink and tea-bag were processed with safflower seed powder. Drinks were processed with 90$^{\circ}$C hot water extraction. Yield, soluble solid, pH and centrifugation residue of drinks were ranged in 79.2~89.3%, 0.6~0.99%, 5.98~6.40 and 1.00~1.18, respectively. Sensory score of overall acceptance in drinks were highest at that of enzyme treated drink. Tea-bag was processed with roasted safflower seed powder, alone(1.2g) and the mixtured tea-bags were consisted of persimmon leaves, pine needle and angelica gigas powder in same amount, respectively. Teas were prepared with extraction at 80$^{\circ}$C water for 2 min. Soluble solid and sensory evaluation score of teas were the highest when the tea was processed with safflower seed alone.

Activated carbon is proposed as a new application of wastepaper recycling other than the paper-making. Waste kraft bag is considered to be a suitable raw material for activated carbon because of its low ash content. Small pellets of wastepaper squeezed out from the continuous kneader were carbonized in a nitrogen atmosphere and activated using carbon dioxide. The BET specific surface areas of activated carbon prepared from waste kraft bag was $1,285m^{2}/g$, which is higher than commercially available activated carbons. The activated carbon prepared from wastepaper has a well-developed porous structure, particularly in mesopore and macropore ranges. As a result, activated carbon with iodine adsorption capacity of 1,400 mg/g was obtained from waste kraft bag. In this paper, adsorption amount of Bisphenol A (BPA) was determined to investigate adsorbability of activated carbon from waste kraft bag. Adsorption measurements were on solutions ranging from $0.1{mu}g/L\;to\;100mg/L$. The activated carbon from waste kraft bag gave higher BPA adsorbabilities over a wide range, compared with commercially available activated carbons.

본 연구는 논에서 재배된 옥수수를 이용하여 AG-BAG 사일리지의 품질에 미치는 영향을 구명하기 위하여 충남 석문 간척지에서 수행되었다. 옥수수 AG-BAG 사일리지의 수분함량은 68~79% 범위를 유지하였고, pH는 3.49-3.65을 유지하였으며 수확기간에 따른 차이는 크지 않았다. 수확기가 늦어짐에 따라 AG-BAG 사일리지의 조단백질 함량은 감소하는 경향을 보였으나 섬유소인 NDF 및 ADF 함량은 증가하였다. 또한 수확기가 늦어짐에 따라 젖산 함량은 증가되었으나(P<0.05) 초산 함량은 감소되었다. 따라서 본 연구에서는 대단위 간척지 논에서 재배된 옥수수 사일리지 제조에 AG-BAG의 이용은 사일리지 발효가 양호하여 품질을 향상시켰을 뿐 만 아니라 옥수수 사일리지 제조에 경제적이며 효율적인 방법의 하나가 될 수 있다는 것을 보여주었다.

The purpose of this study was to compare degree of complication and discomfort between application ' non-application of a sand bag after 3hours, 6hours, 18hours of a cardiac catheterization. The results were as follows : 1) There was no difference in a degree of occurrence of a complication and pain of the femoral punture site between application and non-application of a sand bag after the cardiac catheterization. 2) A degree of a discomfort between application and non-application of a sand bag after the cardiac catheterization recorded the highest scores in the application group of a sand bag 6 hours after the cardiac catheterization.

In this study, the $N_2O$, emitted from combustion facility, were analyzed by using simulated gas and field samples to find out how long samples can be stored in Tedlar bag. According to the results of the experiment using simulated gases (1 ppm, 5 ppm, 10 ppm) in Tedlar bag, After 144hr, $N_2O$ concentration of simulated gases changed that 1 ppm is 5.3%, 5 ppm is 12.8%, and 10ppm is 10.5%. The higher initial concentration of simulated gas was, the larger rate of $N_2O$ concentration was changed. In case of high concentration samples, it need to be careful when it was analyzed after 144 hr. Stability evaluation in Tedlar bag was carried out through field samples such as combustion facility of bituminous coal, B-C oil and LNG. The concentration rate of field samples, which is under 1 ppm of average initial concentration, was evaluated using statistical method. As a result, $N_2O$ concentrations were changed to field samples in the bag even when 96 hr had passed. And after sampling, it is necessary that sample analysis should be quickly as soon as possible.

Previously we showed that CHIP, a co-chaperone of Hsp70 and E3 ubiquitin ligase, can promote the degradation of mutant SOD1 linked to familial amyotrophic lateral sclerosis (fALS) via a mechanism not involving SOD1 ubiquitylation. Here we present evidence that CHIP functions in the interaction of mutant SOD1 with 26S proteasomes. Bag-1, a coupling factor between molecular chaperones and the proteasomes, formed a complex with SOD1 in an hsp70-dependent manner but had no direct effect on the degradation of mutant SOD1. Instead, Bag-1 stimulated interaction between CHIP and the proteasome-associated protein VCP (p97), which do not associate normally. Over-expressed CHIP interfered with the association between mutant SOD1 and VCP. Conversely, the binding of CHIP to mutant SOD1 was inhibited by VCP, implying that the chaperone complex and proteolytic machinery are competing for the common substrates. Finally we observed that mutant SOD1 strongly associated with the 19S complex of proteasomes and CHIP over-expression specifically reduced the interaction between S6/S6' ATPase subunits and mutant SOD1. These results suggest that CHIP, together with ubiquitin-binding proteins such as Bag-1 and VCP, promotes the degradation of mutant SOD1 by facilitating its translocation from ATPase subunits of 19S complex to the 20S core particle.

제조방법이 간편하고 감미도가 높은 새로운 식혜 제조 방법을 개발하였다. 역가가 높은 엿기름만을 분획하여 Tea-bag$(16{\times}20cm)$에 넣어 엿기름 추출공정을 간편하게 하였으며 여기에 ${\alpha}-amylase$, glucoamylase, glucoisomerase를 첨가하여 쌀 전분의 분해를 촉진시켜 단맛이 강한 단당류로 분해되도록 하였다. 식혜의 제조는 엿기름과 효소를 넣은 Tea-bag을 물로 추출한 후 여기에 고두밥을 넣어 당화시켰다. 재래식 방법에 의하여 만든 식혜의 당 조성은 fructose 1.8%, glucose 7.5%, maltose 49.5%, DP3 8.6% 그리고 DP4 이상이 32.5%이었으나 본 연구에서 개발된 방법에 의하여 제조한 식혜는 fructose 6.7%, glucose 89.0%, maltose 1.9%, DP3 0.9% 그리고 DP4 이상이 1.6%로 나타나 쌀 전분의 대부분이 단당류로 분해가 되어 설탕 첨가없이도 감미가 높은 식혜를 제조할 수 있었다.

정치망 원통의 거동을 장기선 방식으로 측정할 수 있는 계류식 수중위치측정시스템을 제작하고, 그 실용성을 확인하기 위하여 소조기 (2000. 10. 6)와 대조기 (2000. 11. 28)에 현장실험을 실시하였다. 현장실험에서 4개의 트랜스폰더는 원통의 남북방향으로 부착시키고, 1개의 트랜스폰더는 해저에 고정시켰다. 그리고, 원통까래의 상하진동은 3개의 테이터로거를 원통의 동서방향 (원통의 길이 방향)으로 부착시켜 대조기에 관측하였다. 소조기에 측정한 원통의 동서방향, 남북방향, 상하방향의 변화폭은 각각 3.2 m, 3.4 m, 2.1 m이었고, 대조기에는 각각 7.8 m, 7.8 m, 5.0 m로 소조기보다 2.3배 이상 컸다. 원통까래의 상하진동폭은 비탈그물에 가까운 쪽이 3.2 m, 중앙부가 3.7 m, 머거리쪽이 8.4 m이었다. 전반적으로 유속이 10 cm/s 이상일 때와 흐름의 방향이 원통의 길이방향과 일치하지 않을 때에 까래의 심도 감소와 상하진동이 빈번하게 발생하였다. 해저에 고정시킨 트랜스폰더를 사용하여 수파기 좌표의 변동을 측정한 결과, 정치망 사개에 부착한 수파기라도 흐름에 의해 그 좌표가 수 m 정도 변함을 알 수 있었고, 정치망의 거동 측정시 이러한 좌표의 변동을 보정하여야 측정오차를 줄일 수 있음을 알 수 있었다. 본 연구에서 제작한 3차원 수중위치측정시스템의 위치오차는 가두리에서 측정한 결과, x축, y축, z축이 각각 0.6 m, 0.8 m, 1.2 m이었고, 기선의 내부이거나 기선에 가까울수록 작았다.
