장명준,하태문,주영철,Jang, Myoung-Jun,Ha, Tae-Moon,Ju, Young-Cheol 한국버섯학회 2007 한국버섯학회지 Vol.5 No.2

생육온도가 증가함에 따라 $CO_2(ppm/hr/m^3$/병)농도는 증가하였고, 생육단계별로는 생육후기에 가장 높은 경향을 나타내고 있으며, 품종별로 춘추2호<수한2호<청풍<진미<흑백 순으로 호흡량이 많은 경향을 나타내었다. 또한 생육 온도가 높아짐에 따라 $O_2(ppm/hr/m^3$/병)소비량은 증가하는 경향이었으며, 생육단계별로 생육후기에 가장 많이 소비되는 경향을 보이고 있고, 품종별로 춘추2호<수한2호<청풍<진미<흑백 순으로 소비된 $O_2$량이 많아지는 경향이었다. 그리고 느타리버섯의 생육적정 온도인 $15^{\circ}C$에서의 호흡지수는 춘추2호가 500일 때, 수한2호 528, 청풍 573, 진미 617, 흑백 634로 신품종의 호흡지수는 춘추2호 보다 높은 경향을 나타내었다. This study was carried out to find out respiration characteristics of new variety of oyster mushroom to the temperature response. In new species of oyster mushroom, the account of respiration was on the increase when the growth temperature with the passage of growth stage was on the rise. The $CO_2$ concentration was accelerated as increasing the growth temperature, whereas the $O_2$ concentration was decreased. The account of respiration of new variety was in the descending order, Hukbaek>Jinmi>Chungpung>Suhan2>Chunchu2. Also, the ventilation exponent at $15^{\circ}C$ was Suhan2 2 ~12%, Chungpung 9~24%, Jinmi 15~37%, Hukbaek 17~39% in proportion to Chunchu2. The experiments related to respiration characteristics of new variety of oyster mushroom were worthy of recommending to new variety cultivator.

This study was carried out to elucidate suitable spawn culture for an artificial cultivation of Neolentinus lepideus. The optimum culture conditions of the liquid spawn were deffated soy flour for main material, 12 days for culture period and 0.9 vvm for aeration volume, respectively. Sawdust spawn was appropriate for douglas fir sawdust and deffated corn flour (95:5, v/v) for mycelia growth and fruiting body formation. In case of liquid spawn, cultivation period was two shorter than sawdust spawn and mushroom yield was 111.9 g per 850ml cultivation bottle. In conclusion, the suitable spawn for fruiting body production was found to be liquid spawn than sawdust spawn with considering cultivation period and mushroom productivity.

장명준(Myoung-Jun Jang),하태문(Tae-Moon Ha),이윤혜(Yun-Hae Lee),주영철(Young-Cheol Ju) (사)한국생물환경조절학회 2009 생물환경조절학회지 Vol.18 No.3

춘추느타리 2호의 최적 환기횟수는 발이유도기 1/10h?¹, 생육초기 1/6h?¹, 생육중기와 생육후기 1/4h?¹에서 자실체의 생육이 양호하였고, 수한느타리 2호는 발이유도기 1/6h?¹, 생육초기 1/6h?¹, 생육중기 1/4h?¹, 생육후기 1/2h?¹에서 자실체의 생육이 양호하였다. 춘추느타리 2호 및 수한느타리 2호 원기형성기에는 이산화탄소의 농도의 영향이 크게 나타나지 않았지만, 자실체 생육시 1,500ppm 이상일 경우 갓의 끝부분이 위로 말려 올라가는 등 환기장해 현상이 나타났다. 이와 같은 결과로 춘추느타리 2호에 비해 수한느타리 2호의 경우 호흡량이 높아져서 환기요구도가 높았으며, 환기 횟수가 클 경우 생육이 양호하였다. In this study, we investigated the effects of the number of air exchanges (NAE) on shape fruit body in two oyster mushrooms, Chunchu 2# and Suhan 2#. The suitable NAEs of Chunchu 2# were 1/10h?¹ at primordial induction, 1/6h?¹ at early stage of growth, 1/4h?¹ at middle stage of growth, 1/4h?¹ at late stage of growth and those of Suhan 2# were 1/6h?¹ at primordial induction, 1/6h?¹ at early stage of growth, 1/4h?¹ at middle stage of growth, and 1/2h?¹ at late stage of growth. In those conditions, the fruit bodies grew well. CO₂ concentration hardly affected the primordial formation of both mushrooms. However there were ventilation disturbances over 1500ppm. For instance, the end of pileus rolled up etc. As a result, Suhan 2# required higher ventilation compared with Chullchu 2# and the lower NAE was favorable for growth.

챔버와 재배사내에서 실험한 결과 풍속에 따른 자실체의 형태 및 수량은 풍속이 약할수록 양호하였으며, 느타리버섯 재배시 적정 풍속으로 0.3m/s를 유지하고, 기존의 냉난방 유닛쿨러에 인버터(속력변환장치)를 이용하여 풍속을 조절하여 할 것으로 판단된다.

0.18㎛ CMOS Technology에서 인터커넥트 라인에 의한 지연시간의 게이트 폭에 대한 의존성 분석

장명준(Myoung-Jun Jang),李熙德(Hi-Deok Lee) 大韓電子工學會 2000 電子工學會論文誌-SD (Semiconductor and devices) Vol.37 No.11

본 논문에서는 인터커넥트 라인을 구동하는 CMOS소자의 게이프 폭의 변화에 따라 소자 및 인터커넥트 라인에 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 전체 회로의 지연시간이 최소가 되는 MOSFET 크기가 존재함을 수식적으로 제안하고 실험치와 비교하여 잘 맞음을 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 nil 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.

This study was carried out to elucidate suitable supplementary nutrition for Neolentinus lepideus cultivation. The main substrate for cultivation was douglas fir sawdust, and supplementary materials for experiment were corn meal, corn hull, corncob, beet pulp, and potato starch. The higher amount of total nitrogen source was showed in corn meal (0.45%) than any other nutritive materials. Incubation ratio and cultivation period showed the best 97% and the shortest 43 days on medium with corn meal substrate. The fruit body yield and biological efficiency on medium with 10% corn meal were highest 122 g/1 kg and 35%, respectively. Factor analyses concerning fruiting yield showed total nitrogen source (r=0.95) and crude fat (r=0.65). These results are recommended that N. lepideus cultivation is corn meal material as the source of the supplementary nutrition and total nitrogen source as the factor of fruiting body yield on the Douglas fir sawdust medium.

동절기 온도가 꽃매미 월동 알의 생존율에 미치는 영향

이영수,장명준,김진영,김준란,Lee, Young Su,Jang, Myoung Jun,Kim, Jin Young,Kim, Jun Ran 한국응용곤충학회 2014 한국응용곤충학회지 Vol.53 No.3

꽃매미는 약충과 성충이 무리지어 식물체 흡즙하거나 그 과정에서 감로를 배출하여 그을음병을 유발시킴으로서 포도 등에 피해를 주는 외래해충이다. 본 연구는 경기도내 주요 포도 재배지에서 꽃매미의 발생특성과 월동기 극저온이 꽃매미 월동난괴의 생존율에 미치는 영향을 분석하기 위해 2010년부터 2013년까지 수행하였다. 경기지역에서 꽃매미 월동난괴는 5월 상순부터 부화하기 시작하여 5월 중순에 가장 높은 약충 밀도를 보이고 있으며 7월 하순부터 출현한 성충은 11월 상순까지 산란하는 특성을 보였다. 동절기 온도가 꽃매미 월동난괴 생존율에 큰 영향을 미쳤으며, 1월 중 극저온 출현일수(x)와 생존율(y) 간 관계를 선형회귀모형으로 분석하였다. 그 결과 예측치와 실측치 간 잔차자승합(residual sum of square) 가장 낮은 모형은 $-11^{\circ}C$를 임계 극저온으로 취급한 y = -1.0486 x + 94.496 ($R^2=0.7067$) 이었다. 본 연구 결과는 월동 중 꽃매미 알의 생존율 예측과 봄철 발생시기 정보를 제공함으로써 꽃매미 관리전략 수립에 유용하게 활용될 수 있을 것으로 판단된다. Lantern fly(Lycorma delicatula) is a major invasive pest that causes withering symptom of agricultural crops by sucking tree sap and sooty mold symptom by producing honeydew. This study was conducted to investigate the occurrence pattern of lantern fly in grape orchards in Gyeonggi area and the effect of winter temperature on L. delicatula egg survival during 2010 to 2013. In Gyeonggi areas, overwintered L. delicatula eggs began to hatch from early May and nymphs peaked in mid May. Adults emerged from late July and laid eggs until early November. The survival of L. delicatula eggs during overwintering was largely affected by winter temperatures. The relationship between the number of days below a threshold temperature (x) in January and the survival rate of overwintering L. delicatula eggs (y) was using linear regression model. The best model selected by the lowest RSS (residual sum of square) between predicted and actual survival was y = -1.0486 x + 94.496 ($R^2=0.7067$) with $-11^{\circ}C$ of threshold temperature. These results should be helpful to conduct L. delicatula management programs, since the results provided relivable prediction for the winter survival of L. delicatula eggs and the phenology of egg hatch in the spring.

The purpose of this study was to investigate eco-friendly measures to manage major diseases which cause heavy economic damages to ginseng. Morphological, physicochemical, and molecular biological species identification was carried out after isolating useful antagonistic bacteria from ginseng fields. In addition, optimal conditions for mass culture were established, and he efficacy of the bacteria in the prevention of the diseases was verified in the field. The results showed that about 150 bacteria were extracted from 150 ginseng fields in the whole county. Among them, B. pyrrocinia LA101 was finally selected, which had a strong antagonistic potency against Alternaria panax, Botrytis cinerea, Rhizoctonia solani, and Cylindrocarpon destructans on agar media. The B. pyrrocinia LA101 is a baculiform gram-negative bacterium identified as Burkholderia pyrrocinia according to results from an API(Analytical Profile Index) kit, 16S rRNA, and gyrase gene sequencing analysis. It was donated to the microbe bank of the Agricultural Genetic Resources Center at the National Academy of Agriculture Science under the Rural Development Administration on September 28, 2011 (Donation No. KACC91663P). A patent for the mass culture technology was granted in August 2012 (Patent No. 10-1175532).
