  • 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. $CO_2$ 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 Chunchu 2# and the lower NAE was favorable for growth.

  • 느타리 버섯의 다양한 품종과 재배형태가 급변히 요구되는 시기에 충남농업기술원 버섯연구팀의 5년 (1996~2,000)에 걸쳐 국,내외 수집 20 균주를 공시하여 개발 육성한 청풍과 명월 신품종 느타리버섯을 현재 재배되고 있는 기존 느타리품종과 동일여부를 위해 PCR-RAPD분석과 배양적, 재배적 특성을 인공재배 시험한 결과를 요약하면 다음과 같다. 1. 청풍, 명월느타리버섯 균사배 양 온도는 청 풍은 20~$25^{\circ}C$,명 월은 25~3$0^{\circ}C$, 이고 배지는 PDA배지가 양호하고 균사생육은 청풍, 명월 모두 비슷하였으며 배지 pH는 6.5~7.5 였다. 2. 버섯재배가능은 청풍은, 5~26$^{\circ}C$ 명 월은, 7~28$^{\circ}C$로 온도범위가 넓어 재배가 용이하나 적정 생육온도는 청풍, 명월 공히 15~19$^{\circ}C$가 양호 하였다 3. 청풍과 명월의 배양온도 23$^{\circ}C$에서 균사배양기간 23~24일 (850cc/pp),폐면 균상 재배에서 균배양 기간은 청풍, 명월 공히 11~12일, 초발이 소요일수는 2~3일 소요 되었다. 4.초발이시 청풍과 명월 갓 색택은 진청색이고, 생육후기 청풍은 회갈색, 명월은 진회색으로 조직이 치밀하고 저장성이 양호하여 경제성이 기대된다. 5. 다발수는 춘추2호 (13개/다발) 대 비 청 풍11개, 명월12개로 약간 적었으나 개체중은 춘추2호(14g/개) 대비 청풍 16g/개, 명월 14g/개로 비슷한 경향 이었다. 6. 수량성은 균상 폐면재배시 춘추2호 (40kg/3.3$m^2$)대비 청풍 느타리버섯은 (46kg/3.3$m^2$) 15%증수되고, 명월느타리버섯은(41kg/3.3$m^2$)로 3% 증수되었으며 병재배 겸용도 가능하였다. 7. PDA대치배양과 PCR-RAPD시험에서 청풍, 명월 신품종느타리 버섯은 기존 재배 되고 있는 느타리품종과 다른 품종으로 확인 되었다.

  • Hybrid strains was selected by crossing between dikaryotic strain ASI 0628 (Dagul) bred from ASI 2596 (Suhan No.3) and ASI 2782(Black pileus mutant) and monokaryotic strain ASI 2344-84. The strain 84 that shown the best cultural characteristics was selected to be a new cytoplasmic hybrid variety and named as 'Chunhwashim'. The 'Chunhwashim' shown incompatibility among them forming the confrontation growth line against parental strains ASI 0628 (Dagul) and ASI 2344 (chunchu 2ho). Fruiting body produced about $161.4{\pm}4.8g$ per bottle. And also the individual generation of fruit body is multiple than chunchu2ho as 40.9. The 'Chunhwashim' was cytoplasmic hybrid included hybrid DNA bands of parental strains ASI 0628 (Dagul) and ASI 2344 (chunchu 2ho) by Random Amplified Polymorphic DNA (RAPD) primer, and mitochondria DNA band of monokaryotic ASI 2344 (chunchu 2ho) using mitochondria microsatellite DNA marker. This new cytoplasmic hybrid variety 'Chunhwashim' of oyster mushroom is characterized by multiple of individual generation and deeply grey color of pileus.

  • This study was carried out to observe the possibility of special rearing of young silkworm for a simple cooperative rearing in the indoor vinyl house. The results of this study are as follows. 1. Temperature and humidity were regulated reasonably in the indoor vinyl house in comparison with general rearing and covered rearing with damp-proof and all workings in it were more convenient. 2. Duration of silkworm life was same in the covered rearing with damp-proof and indoor vinyl house, but general rearing was longer spring rearing silkworm period, 5 hours and autumn young silkworm period. 6 hours than indoor vinyl house. 3. In the mortality ratio, missing larvae of general rearing was more than any other treatments in spring and autumn. There was no difference between covered rearing with damp-proof and indoor vinyl house rearing, but missing larvae seemed to be a little indoor vinyl house. 4. In the individual cocoon ratio there was no significance in spring and autumn, but best cocoon ratio was high in the special rearing and good and low cocoon ratio was high in the general rearing. 5. In the cocoon weight of 10,000 3rd moulted silkworm. cocoon weight of general rearing was less than any other treatments in spring rearing season, and that of covered rearing with damp-proof and indoor vinyl house rearing It was same result. 6. There was no significance in the cocoon layer ratio in spring and autumn, but that of covered rearing with damp-proof and indoor vinyl house was high in comparison with general rearing. 7. As showed above, it is considered that the rearing of indoor vinyl house is worth as special rearing of young silkworm for simple cooperative rearing because it showed good records with three times feedings a day in comparison with general rearing and covered rearing with damp-proof.

  • In the early days of human history, the governing groups of rulers needed to justify their rule. The cause of rule became the ruling ideology. In China, the backbone of the ruling ideology was originally referred to as 'Di(帝)' or 'Shangdi(上帝)', who was later replaced by 'Tian(天)', Heaven. So there was a claim that Heaven gave the cause of the rule. This idea is the 'Tianming (天命)' idea. When the Zhou(周) Dynasty took control of the central government, the 'Tianming' idea had had a relatively sophisticated form. It was the 'Zhouli(周禮)' that organized the systematic order of the Zhou Dynasty. After this system collapsed, those who recognized 'Zhouli' as a desirable social system considered the collapse of 'Zhouli' as a situation of turbulent age. It was Qin(秦) State that unified all of the states of the period. However, after the unification, the Qin Dynasty fell sharply. The next dynasty was the Han(漢) Dynasty. The new ruling powers of the Han Dynasty needed to justify their regime. That means that it was necessary to establish the ruling ideology of the Han Dynasty. The representative of the ruling ideology of the Han Dynasty was Dongzhongshu, whose thought was based on Confucianism. His thought was related to "Chunqiugongyangzhuan(春秋公羊傳)", an interpretation of "Chunqiu(春秋)". This interpretation perspective is based on the idea of religious Heaven. Dongzhongshu thought that there were co-communions between Heaven and humans. His thought has the meaning of political theology in which rulers hold the basis of the rulers' sovereignty.
