Attempts to search infection period, infection speed in the tissue of neck blast of rice plant, location of inoculum source and effects of several conditions about the leaf sheath of rice plants for neck blast incidence have been made. 1. The most infectious period for neck blast incidence was the booting stage just before heading date, and most of necks have been infected during the booting stage and on heading date. But $Indica{\times}Japonica$ hybrid varieties had shown always high possibility for infection after booting stage. 2. Incubation period for neck blast of rice plants under natural conditions had rather a long period ranging from 10 to 22 days. Under artificial inoculation condition incubation period in the young panicle was shorter than in the old panicle. Panicles that emerged from the sheath of flag leaf had long incubation period, with a low infection rate and they also shown slow infection speed in the tissue. 3. Considering the incubation period of neck blast of rice plant, we assumed that the most effective application periods of chemicals are 5-10 days for immediate effective chemicals and 10-15 days for slow effective chemicals before heading. 4. Infiltration of conidia into the leaf sheath of rice plant carried out by saturation effect with water through the suture of the upper three leaves. The number of conidia observed in the leaf sheath during the booting stage were higher than those in the leaf sheath during other stages. Ligule had protected to infiltrate of conidia into the leaf sheath. 5. When conidia were infiltrated into the leaf sheath, the highest number of attached conidia was observed on the panicle base and panicle axis with hairs and degenerated panicle, which seemed to promote the infection of neck blast. 6. The lowest spore concentration for neck blast incidence was variable with rice varietal groups. $Indica{\times}Japonica$ hybrid varieties were infected easily compared to the Japonica type varieties, especially. The number of spores for neck blast incidence in $Indica{\times}Japonica$ hybrid varieties was less than 100 and disease index was higher also in $Indica{\times}Japonica$ hybrid than in Japonica type varieties. 7. Nitrogen content and silicate content were related with blast incidence in necks of rice plants in the different growing stage changed during growing period. Nitrogen content increased from booting stage to heading date and then decreased gradually as time passes. Silicate content increased from booting stage after heading with time. Change of these content promoted to increase neck blast infection. 8. Conidia moved to rice plant by ascending and desending dispersal and then attached on the rice plant. Conidia transfered horizontally was found very negligible. So we presumed that infection rate of neck blast was very low after emergence of panicle base from the leaf sheath. Also ascending air current by temperature difference between upper and lower side of rice plant seemed to increase the liberation of spores. 9. Conidial number of the blast fungus collected just before and after heading date was closely related with neck blast incidence. Lesions on three leaves from the top were closely related with neck blast incidence, because they had high potential for conidia formation of rice blast fungus and they were direct inoculum sources for neck blast. 10. The condition inside the leaf sheath was very favorable for the incidence of neck blast and the neck blast incidence in the leaf sheath increased as the level of fertilizer applied increased. Therefore, the infection rate of neck blast on the all panicle parts such as panicle base, panicle branches, spikelets, nodes, and internodes inside the leaf sheath didn't show differences due to varietal resistance or fertilizers applied. 11. Except for others among dominant species of fungi in the leaf sheath, only Gerlachia oryzae appeared to promote incidence of neck blast. It was assumed that days for heading of varieties were related with neck blast incidence.

Objective : This study was performed to investigate the childpsychiatric diseases in oriental medicine. Method : Several main testbooks and paper of oriental medicine in Korea and China were selected and investigated for this study. And then the results of research were analyzed, and compared to DSM-IV. Results and Conclusion : Some childpsychiatric diseases in oriental medicine like oyun(五軟), ojie(五遲), ogyung(五硬), yaje(夜啼), kaego(客?), kueji(鬼持), kibyung(?病) and so on, were revealed. It seems that they are analogous to mental disorders of western psychiatry.

동의보감(東醫寶鑑) "내경편(內景篇)"에 "사람의 형은 긴 것이 짧은 것만 못하며, 큰 것이 작은 것만 못하고, 살찐 것이 마른 것만 못하다. 사람의 색은 흰 것이 검은 것만 못하고, 옅은 것이 짙은 것만 못하며, 엷은 것이 두터운 것만 못하다. 더욱이 살찐 사람은 습이 많고, 마른 사람은 화가 많으며, 흰 사람은 폐기가 허하고, 검은 사람은 신기가 넉넉하다. 사람마다 형색이 다르면 오장육부 역시 다르기 때문에 외증이 같더라도 치료방법을 달리해야 한다."고 하였다. 이것은 "동의보감(東醫寶鑑)"의 체 병 증을 서로 결합하여 진단 치료하는 사상으로 "이체질동병이치", "이체질동증이치"의 체질진료사상을 나타낸 것이다. "동의보감(東醫寶鑑)" "탕액편(湯液篇)"에서 "약이란 병을 치료하는 것이다. 변화하는 것은 병에 있고, 병 치료를 주관하는 것은 약에 달렸으며, 약을 만들어 쓰는 것은 사람에게 달려 있다. 이 셋 중 하나라도 빠지면 안된다."고 하였다. 이것은 체 병 증과 방약이 서로 대응하는 용약사상을 보여주는 것으로 동의약의 진료체계를 건립하였는데 이 점이 바로 동의약학의 장점이자 특색이라 할 수 있다.

Transplanting date, planting space and nitrogen level were evaluated for disease development of rice sheath blight using two rice cultivars, Jinheung and Yushin. Sheath blight disease was more severe in early transplanting plot (May 16), narrow planting space($27{\times}12cm$) and high nitrogen level (220kg/ha for Jinheung and 300kg/ha for Yushin) conditions than in May 26 transplanting plot, wide planting space ($27{\times}15cm$) and standard nitrogen level (110kg/ha and l50kg/ha). At the same time, cultural conditions favorable for disease development during growth stage resulted in greater damage at maturing stage.

Powdery mildew has been observed on the several clones of Populus euramericana, P. deltoides, P. deltoides ${\times}$ P. maximowiczii in the nurseries of Chuncheongan-do and Kangwoen-do forest Research Institute in mid-October 1982. Powdery mildew fungus of Populus spp. was identified as phyllactinia guttata(Waller. ex Fr.) $L{\acute{e}}v$ which was reported as the powdery mildew fungus of Populus tomentosa Carr. Powdery mildew of Populus spp. caused by this fungus has not previously been reported in Korea. When we surveyed the occurrence of powdery mildew disease the leaves of P. deltoides R-89 were severely attacked by this fungus.
