Objectives : This study was designed to compare the demographic data, clinical characteristics, developmental delay, and psychological tests between childhood-onset and adolescent-onset schizophrenic in-patients. Methods Medical records of the 17 childhood-onset (very early onset) Schizophrenia and 16 adolescent-onset (early onset) Schizophrenia in-patients were reviewed. Sex, age, psychiatric past history, prodromal symptoms and period, subtype, co-morbid disease, developmental delay, prescribed drug and dosage, treatment response, intelligence quotient (IQ), and Rorschach test were evaluated. Results : The mean admission age of childhood-onset (very early onset) group and adolescent-onset (early onset) group were 12.69$({\pm}2.34)$ and 15.13$({\pm}1.04)$ years. The mean onset age of childhood-onset(very early onset) group and adolescent-onset (early onset) group were 10.79$({\pm}1.95)$ and 14.46$({\pm}0.82)$ years. The mean prodromal period of childhood-onset (very early onset) group and adolescent-onset (early onset) group were 15.94$({\pm}12.33)$ and 8.06$({\pm}6.10)$ month. The time to remission period of childhood-onset (very early onset) group and adolescent-onset (early onset) group were 50.58$({\pm}24.67)$ and 30.06$({\pm}18.04)$ days. Longer time to remission period in childhood-osnet (very early onset) group was associated with earlier age of onset. The mean of total IQ, performance IQ, verbal IQ were at an average level. Discussion : Childhood-onset (very early onset) group and adolescent-onset (early onset) group Schizophrenia had different clinical and psychological features including prodromal period, and IQ subtests.

댁의 벌에 미국부저병(AFB)이 발병해 다음해 수익을 기약할 수 없게 됐는데, 내가 만약 간단한 검사방법으로 미국부저병이 발병하기전 발병 유무를 알 수 있다고 말한다면 흥미가 가겠는가? 더욱이 발병을 막을 수 있는 간단한 처치방법이 항생제를 포함하지 않는가면 말이다.

옥수수 유묘접종시 깜부기병이 가장 잘 발병하는 조건은 4엽기 옥수수묘를 10\ulcorner~10\ulcorner/ml 농도의 소생자 현탁액으로 경엽살포한 후 28~3$0^{\circ}C$의 습실상에서 24시간 둔 후 꺼내어 온실에 두었을 때였다. 유묘의 엽기가 이보다 어리거나 접종원 농도가 이보다 높을 때, 혹은 습실상내 처리기간이 길어지면 접종후 유묘의 이른 고사를 초래하였다. 또한 습실상의 온도가 낮아질수록 깜부기병의 발병정도도 감소하였다. 깜부기병의 발생은 소생자 현탁액의 경엽살포 및 줄기주사접종에 의해서는 가능하였지만 토양관주에 의해서는 발병하지 않았다. 소생자 현탁액은 별도의 영양원의 첨가 없이도 발병을 잘 유도하였다. 동포자 현탁액을 직접 경엽살포하거나 줄기주사접종하여도 발병하였으나 소생자 현탁액접종에 비하여 발병정도가 현저히 낮았다.

It has been tried to find effective biological control measures involved in nature of soil suppressiveness to fusarium wilt of cncumber caused by Fusarium oxysporum f. sp. cucumerinum Owen. Total 28 soil samples were obtained from Jinju, Haman, Namji, Milyang and Suncheon vinyl house area. The disease response of test soil was quantified in terms of DI50 value which caculated from log-probit transformation of diseases response curves. Soils designated 5 from Jinju, 7 from Suncheon, 22 from Namji were recognized as suppressive to fusarium wilt of cucumber. This suppressiveness was completely nullified after autoclave. The disease suppressiveness of tested soil did not indicate any consistency according to either chemical property or texture of soil. Conidial germination, induction and germination of chlamydospore were markedly inhibited in supprerssive soil compared to those in intermediate or conducive soils, however, mycelial lysis did not appear to have direct relationship with disease suppressiveness of given soil. Population density of fluorescent Pseudomonads and Bacillus spp. in the soil originated from different degree of suppressiveness were not different significantly but the number of lytic bacterial plaques measured by triple layer agar method was remarkably higher in suppressive soil than that in intermediate or conducive soil.

The study has been carried to confirm pathogenesity among the isolates which obtained from leaf blight type symptoms and Kresek type symptoms, and also to observe varietal resistance among 29 varieties and/or lines through the introduction of two different pathotypes, of Xanthomonas oryzae, by the use of root clipping and pin prick methods. There was no significant differences among the isolates when their growth in plant tissue were compared. There was certain tendency, however, that the isolates from Kreseked plants showed longer lesion than those from blight type lesions. Both isolates from blight type and Kresek type induced the same degree of Kresek syptoms when they were introduced into plants by root cutting in the suspension prior to transplant. Varietal resistance to 'Kresek' appeared to be the same with those on leaf blight type though Wase Aikoku group varieties showed Kresek symptoms which is not the case with leaf blight type. IR 20 in Kogyoku group varieties showed highly resistant reaction to Kresek type. Root clipping method induced the more of Kresek than those by pin pricking method.

벼 담수직파재배에서 Pythium arrhenomanes 1398에 의한 벼목썩음병의 발병 억제효과가 높은 biological control agent를 배지와 growth chamber 검정을 통하여 선발하고 생물학적 방제 효과를 온실에서 검정한 결과 공시한 66 세균 중 91-110 균주에 의해서만 벼모썩음병의 발병이 억제되었다. CMA 배지 검정에서는 P. arrhenomanes 1398 균주만을 접종한 볍씨는 100% 발병율을 보인 반면 91-110 균주와 P. arrhenomanes 1398 균주를 함께 처리한 경우에는 25.0%가 발병되었으며, 이 효과는 metalaxyl을 처리한 볍씨에서의 21.7% 발병율과 유사하였다. Growth chamber 검정에서는 P. arrhenomanes 1398 균주만을 접종한 볍씨는 27.7% 모 출아율을 보인 반면 91-110 균주와 함께 처리하면 59.1%가 출아되었다. 그러나 91-110 균주에 의한 발병 억제효과는 50% household bleach로 표면 소독한 볍씨에서만 인정되었으며, 이 소독한 볍씨를 91-110 균주의 세균 부유액에 침지하여 3시간 진탕한 후 그 부유액을 따라내고 24시간 배양한 것이 진탕하지 않고 배양한 것에 비하여 모출아율이 54.3%에서 65.7%로 증가되었다. 91-110 균주와 P. arrhenomanes 1398 균주를 함께 처리한 볍씨의 출아율은 62.3%로서 P. arrhenomanes 1398 균주만을 접종한것의 30.8%에 비하여 높았다. 이상과 같이 담수직파한 벼모썩음병의 발병 억제효과가 높은 91-110 균주는 Bacillus brevis로 동정되었다.

많은 사람들이 에이즈의 첫 증상하면 붉은 반점을 흔하게 떠올리게 된다. 사실 이것은 에이즈 전구 증상이 아니고 사람면역결핍바이러스(HIV)에 감염되고 8-10년간의 무증상기를 거친 후에 인체의 면역기능이 바닥까지 망가졌을 때에 생기는 카포시 육종이라는 질병이다. HIV에 감염된 후에 면역기능이 파괴되면 본래 정상인에게 병을 일으키지 않는 미생물에 의해서 감염증이 생기고(이를 기회감염이라고 함)암도 발생하게 된다. 이와 같이 HIV 감염인에게 기회감염 혹은 암 등이 발생한 상태를 에이즈라고 한다. 어떤 사람들은 HIV에 감염된 후에 에이즈가 발병하기 전까지 아무런 증상을 느끼지 못하지만 일부는 에이즈 발병 전에 여러 가지 증상들(에이즈 전구 증상)을 겪게 된다. 오늘은 HIV에 감염된 후 에이즈가 발병하기 전에 발생할 수 있는 전구 증상들에 대해 알아보고자 한다.

It was investigated on the relationship of the rice blast epidemics and the real-time meteorological factors, at the experimental paddy field in 1997. Weather factors(temperature, relative humidity, irradiation, precipitation, the direction of wind, wind speed, soil temperature and leaf-wetness, etc) were measured by using the automated weather station. The most influenced weather factor to blast epidemics, was the average max-temp($R^2$= 0.95) during 10 days before leaf blast epidemics, while the least thing was wind speed($R^2$= 0.24). The most potential weather factors correlated with the blast epidemics were T-ave(average temperature), T-max(maximum temperature), RH(Relative Humidity) and RD(Relative Humidity > 90% hrs). A statistics model(the regression equation) of the blast epidemics with the potential weather factors, was established as tallows ; Y = -3410.91 - 23.91 $\times$ T-ave ＋ 28.56 $\times$ T-max ＋ 41.0 $\times$ RH - 3.75 $\times$ RD, ($R^2$= 0.99). (T-ave >= 19$^{\circ}C$, T-max - T-ave >= 5.2$^{\circ}C$ and RH% >= 90.4%). According to the fitness test($\chi$$^2$) of the model, the observed blast disease severity was quite close to those expected.

In order to investigate the relationship among the occurrence of bacterial leaf blight, amount of nitrogen application and planting density, a field experiment was carried out with factorial combinations of N levels (7.5, 15, 30kg/10a) and planting densities (10\times20,\;15\times30,\;20\times40cm). The results obtained in this study were; (1) The incidence of bacterial leaf blight was increased with increase of nitrogen application; (2) In double amount of nitrogen application (30kg/10a), the incidence of bacterial leaf blight was higher, regardless of planting density; (3) The incidence of bacterial leaf blight in Standard nitrogen application was significantly higher $(R=0.94^{**})$ than at $15\times30cm$ density and $20\times40cm$ planting density.
