$0.18{\mu}m$ CMOS Technology에 인터커넥트 라인에 의한 지연시간의 게이트 폭에 대한 의존성 분석
장명준,이희덕,Jang, Myung-Jun,Lee, Hi-Deok 대한전자공학회 2000 電子工學會論文誌-SD (Semiconductor and devices) Vol.37 No.11
본 논문에서는 인터커넥트 라인을 구동하는 CMOS소자의 게이트 폭의 변화에 따라 소자 및 인터커넥트라인에 의한 RC 지연시간이 어떤 특성을 보이는지에 대하여 분석하였다. 인터커넥트 라인의 캐패시턴스 성분만이 주로 나타나는 구조에서는 MOSFET의 크기가 커질수록 전체 지연시간이 감소하는 특성을 보였다. 반면에 인터커넥트 라인의 저항 및 캐패시턴스 성분이 대등하게 지연시간에 영향을 미치는 구조에서는 전체회로의 지연시간이 최소가 되는 MOSFET 크기가 존재함을 수식적으로 제안하고 실험치와 비교하여 잘맞음을 증명하였다. In this paper, the dependence of interconnect line-induced delay time on the size of CMOSFET gate width is characterized. In case of capacitance dominant interconnect line, the total delay time decreases as transistor size increases. However, there exists a transistor size for minimum total delay time when both of resistance and capacitance of interconnect line become larger than those of transistor. The optimum transistor size for minimum total delay time is obtained using an analytic equation and the experimental results showed good agreement with the calculation.

In this study, we attempted to find substitute materials, distillers residue of cassava, alfalfa pellet, and distillers residue of corn, for cotton seed meal in bottle cultivation of Pleurotus ostreatus. In all treatments, the total carbon content was comparable with the exception of T4, and the total nitrogen content of T3 was similar to the control group, and C/N ratio of T4 was higher than other treatments. The diameter of plieus was the largest in T2, and the diameter of stipe was the largest in T2 and T4. And the length of stipe was largest in T1 and T2, and the most number of available stipes was in T1 and T3. The yield and bio-efficiency of fruit-body by residue of corn with soluble treatment (T3), were similar to the control of P. ostreatus. Therefore, it was suggested that residue of corn was substituted for cotton seed meal for cultivation of P. ostreatus.

This study was focused on finding a relationship between fruit-body growth and relative humidity in Neolentinus lepideus cultivation. The higher the relative humidity, the moisture content of pileus and stipe were also tends to be increased. The day of formation of primordia and development of fruit body was shortest at the relative humidity 95%. The yield and commercial yield were higher in the relative humidity 95% than in the other treatment. Individual weight of fruit body was the highest at the relative humidity 75% and 85%. Crack indices of pileus was the strongest at the relative humidity 65%

잣버섯 액체종균 적정 배지를 선발하기 위해 대두분, 감자 전분, 옥분, 비트펄프, 대두박을 이용하여 실험한 결과 대두 분 배지의 경우 다른 처리구에 비해 생체중이 가장 높았으며, 또한 입경분포가 6.7mm이상인 생체중은 870g이었다. 그리 고 배양일수에 따른 건물중의 변화로 대두분 처리구가 다른 처리구에 비해 전체적으로 높았으며, 모든 처리구에서 배양 9일 이후 건물중이 감소하는 경향이었다. 액체종균 통기량에 따른 배지소모량은 통기량이 많을수록 배지소모율도 높았 고, 통기량에 따른 균사체의 생체중은 배양 12일 후 0.5vvm 에서 가장 높았다. 따라서 잣버섯 액체종균에 적합한 재료로 일반 버섯 재배에 사용되는 대두분 배지가 잣버섯의 액체종 균용 배지로 적합한 것을 확인하였고, 액체종균의 통기량은 0.5vvm에서 균사생장량이 우수하였다. 잣버섯 병재배시 주재료를 선발하기 위해 미송톱밥, 미루 나무톱밥, 잣나무톱밥, 참나무톱밥을 90%, 영양원으로 비트 펄프 10%를 혼합하여 실험한 결과 미송톱밥을 주재료로 이 용할 경우 생육이 가장 양호하였으며, 영양원으로 옥분, 옥 피, 콘코브, 비트펄프, 감자전분을 영양원으로 각각 5%씩 첨 가하여 실험한 결과 옥분을 첨가한 배지에서 생육이 양호하 며, 수량 또한 다른 처리구에 비해 높아 옥분을 최종 영양원 으로 선발하였다. 잣버섯의 봉지재배의 경우도 병재배와 같 이 주재료 및 영양원이 각각 미송톱밥과 옥분으로 선발되었 으며, 옥분 5~15% 첨가시 수량이 100g이상이었고, 회수율 은 옥분 5%첨가배지에서 32.1%, 옥분 10%첨가배지에서 33.1%로 다른 처리구에 비해 높았다.

We aim at providing consumers and farmers with various parts of mushrooms through development of new mushroom cultivation. For the mass artificial cultivation, we elucidated suitable environment conditions of Neolentinus lepideus. The results were summarized as follows. For the efficient cultivation of N. lepideus, temperature of mycelial growth and development of the fruit body were suitable 20~23℃ and 20℃, respectively.

We found about cultivation light environment conditions of Neolentinus lepideus. For the high quality of N. lepideus, lights-out was useful. In the lights-out, the diameter of pileus of N. lepideus was smaller, and the length and the thickness of stipes were longer and larger than in that of lighting. At the LED effect, the orange and red LEDs prolonged the cultivation period in N. lepideus. The yields of N. lepideus under the white, blue and green LEDs were higher, and the number of available stipes of N. lepideus under the white and blue LEDs was higher than that of other LEDs. The diameter of pileus of N. lepideus under the white, blue and green LEDs was higher, and the length and the thickness of stipes under the orange and red LEDs was higher than those of other LEDs.

We aimed to develop a new variety of Neolentinus lepideus from about forty strains by bag culture. To this end, “Solhyang” which means pine smell in Korean was selected as a new commercial variety of N. lepideus. N. lepideus have yellow pileus and pine smell, which characteristics make a favorable impression on the far east Asia, Korean and Japanese. The optimum temperatures for mycelial growth and fruit body development ranged 26~32℃ and 18~20℃, respectively. The required periods of mycelial incubation and fruit body growth were 30 days and 7 days, respectively. The fresh weight of fruit body was 115g/kg with pine sawdust and corn meal power(9:1, v/v) substrate.
