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.

김정한,하태문,주영철,Kim, Jeong-Han,Ha, Tae-Moon,Ju, Young-Cheol 한국버섯학회 2005 한국버섯학회지 Vol.3 No.3

톱밥:비트펄프:면실박(50:30:20) 배지의 면실박 대체배지로서 아주까리박, 유채박을 사용한 경우 C/N율은 대조와 유사하였고, 야자박, 코코넛박을 이용한 배지에서는 대조보다 높은 C/N율을 나타났다. 아주까리박, 유채박 사용시 배양일수는 2~5일, 초발이소요일수는 2일 지연 되었고 수량 또한 대조보다 20g이상 낮게 나타났으며 야자박, 코코넛박 사용시 배양일수는 3일 지연되었으나 수량은 관행재배 128g/병과 비슷하게 나타났다. 경제성 분석결과, 미송톱밥:비트펄프:면실박(50:30:20)의 관행재배에서 면실박 대체배지로 야자박, 코코넛박을 이용시 1000병규모로 연간 8.2회 재배 경우 소득이 각각 2,864천원, 2,733천원으로 관행재배의 2,849천원 대비 101%, 96%의 소득지수를 보였다. Main materials used as media for oyster mushroom cultivation are pine sawdust, beet pulp, cotton seed pomace. Increases in the price and the unbalance of demand and supply of cotton seed pomace was often damage to oyster mushroom cultivation farm, so we investigated agricultural by-product to replace the cotton seed pomace for bottle cultivation of oyster mushroom. Treatment of coconut oil meal or coconut pomace delayed incubation period about 3 days compared with cotton seed waste treatment(control), but yield and income index showed similar to each other in three treatment. Consequently coconut oil meal and coconut pomace could select for cotton seed pomace substitute.

원적외선 처리가 상황버섯과 영지버섯 추출물의 항산화능에 미치는 영향

김정한(Jeong-Han Kim),이승철(Seung-Cheol Lee),주영철(Young-Cheoul Ju) 한국식품과학회 2007 한국식품과학회지 Vol.39 No.4

원적외선 조사가 상황버섯과 영지버섯의 항산화능에 미치는 영향을 조사하기 위하여 30, 60, 90 그러고 120분 간격으로 원적외선을 조사를 한 후, 물 추출물을 제조하여 실험에 이용하였다. 상황버섯 추출물은 원적외선 처리시간에 비례하여 갈변도, 총당, 총페놀, 라디컬소거능 및 환원력이 증가하였으며, 120분 처리 후 갈변도는 2.1배, 총당은 2.6배, 총페놀은 2.2배, 라디컬 소거능은 2.2배, 환윈력은 1.6배 증가하였다. 또한, 원적외선 120분 조사에 의해 영지버섯 추출물의 갈변도, 총당, 총페놀 및 라디컬소거능도 각각 1.7배, 2.0배, 2.3배, 1.3배 증가하였다. 그러나 환원력은 유의적인 차이를 보이지 않았으며, 전체적인 효과는 상황버섯에 비해 다소 낮았다. 이상의 결과 원적외선 조사가 상황버섯과 영지버섯의 당류 및 페놀화합물의 추출을 촉진하여 항산화능을 향상시킴을 확인하였다. The antioxidant activities of Phellinus igniarius (PI) and Ganoderma lucidum (GL) extracts were evaluated after far-infrared (FIR) irradiation. PI and GL were irradiated at 120℃ for 30, 60, 90 and 120 min with a FLR heater (2-14 ㎛), and then extracted by distilled water for 1 hr. Total sugar contents (TSC), total phenolic contents (TPC), radical scavenging ability (RSA), and reducing power (RP) were significantly increased by FIR irradiation. When PI was irradiated for 120 min, the TSC, TPC, RSA, and RP values of the PI extracts increased from 10.1 to 25.9 ㎎/g, 6.1 to 13.4 ㎎/g, 23.8 to 51.5%, and 0.222 to 0.363, respectively, compared to the untreated controls. The GL extracts, under the same conditions (120℃ for 120 min), also increased in TSC, TPC, RSA, and RP from 11.1 to 22.6 ㎎/g, 2.5 to 5.8 ㎎/g, 14.5 to 18.6%, and 0.271 to 0.296, respectively. These results indicate that appropriate FIR irradiation of PI and GL could enhance the antioxidant activities of their extracts by increasing amounts of phenolic and sugar compounds.

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.

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.

In order to provide high-quality medical services to the public and contribute to the improvement of public health, it is necessary to enact an independent law according to the work of radiological technologists. Therefore, this study intends to review the regulations related to radiographers in the Medical Service Technologists, etc. Act. and to present opinions and directions for enactment of individual laws for radiological technologists. An online survey was conducted to 15,000 radiological technologists working in medical institutions and education sites in Korea; 1,027 people (6.85%) responded. The questionnaire consisted of 3 questions on demographic characteristics, 5 questions on the scope of work, and 12 questions on the revision of the Medical Service Technologists, etc. Act. and the establishment of the Radiological Technologist Independent Act. Reliability and factor analysis were performed on 9 questions measured on a Likert 5-point scale in “Revision of the Medical Service Technologists, etc. Act. and the establishment of the Radiological echnologist Independent Act” among the questionnaire items. Reliability for the total 9 questions was Chronbach α=0.728. There was a high perception that the regulations related to radiological technologists were insufficient in the current Medical Service Technologists, etc. Act., and the perception that examinations performed by radiological technologists at medical institutions were included in medical practice was high. If the Radiological Technologist Independent Act is enforced, a high percentage of respondents said that they could receive legal protection through the institutionalization of the scope of work, that the status of radiological technologists would be improved, and the scope of work would be expanded. The response that the scope of work of radiological technologists should be included was the highest at 96.6%. In the analysis according to demographic characteristics, it was found that 96.7% of the respondents were agreed regardless of the factors. Radiological technologists will have to work hard to secure the public health by coping with new radiology devices, procedures and treatment methods. Therefore, as the results of this study, it is expected that the enactment and implementation of the Radiological Technologist Independent Act will contribute to the improvement of the quality of treatment for patients and to the public health.
