연구목적 : 본 시험의 목적은 임상시험 시작전에 연구자들을 대상으로 PANSS Workshop을 통하여 PANSS, ESRS에 대한 국내에서의 표준화 작업을 구축하고 새로운 정신병 치료제인 리스페리돈의 효과와 안정성을 재확인하여 리스페리돈 사용에 대한 적정화를 이루는데 있다. 연구방법 : 1996년 4월부터 1996년 9월까지 국내 39개 대학병원 정신과에 입원중인 혹은 증상이 악화되어 입원하는 정신분열병 환자 377명을 대상으로 다시설 개방 연구를 시행하였다. 1주일간의 약물 배설기간을 가진후, 리스페리돈을 8주간 투여하였고, 기준점, 1주, 2주, 4주, 그리고 8주후에 평가되었다. 용량은 제1일에는 리스페리돈 1mg씩 1일 2회, 제2일에는 2mg씩 1일 2회, 제3∼7일에는 3mg씩 1일 2회 투여하였다. 이후 환자의 임상상태에 따라 임의로 증량할 수 있으며, 최대 일일 16mg을 초과하지 않도록 하였다. 추체외로 증상을 조절하기 위한 투약을 허용하였다. 임상증상 및 부작용의 평가는 PANSS(Positive and Negative Syndrome Scale), CGI(Clinical Global Impression) 그리고 ESRS(Extrapyramidal Symptom Rating Scale)을 사용하였다. 연구결과 : 377명중 343명(91%)이 8주간의 연구를 완결하였다. 치료 종결시점인 8주후 PANSS 총점수가 20% 이상 호전된 경우를 약물 반응군으로 정의할때, 약물반응군은 81.3%였다. 리스페리돈에 반응하는 예측인자로는 발병연령, 이전의 입원 횟수, 유병기간이 관련 있었다. 리스페리돈은 1주후부터 PANSS양성, 음성, 및 일반정신병리 점수상에 유의한 호전을 보여 효과가 빨랐다. CGI의 경우도 기준점에 비해 1주후부터 유의한 감소를 나타내었다. ESRS의 경우, 파킨슨 평가점수는 기준점과 비교해 투여 1주, 2주, 4주후 유의하게 증가되었다가 8주후 기준점과 차이가 없었다. Dystonia 평가점수는 1주후만 유의한 증가를 보였으며, dyskinesia 평가점수는 유의한 차이가 없었다. 혈압, 맥박수의 생명징후 및 일반 혈액학 검사, 생화학적 검사, 심전도 검사에서 유의한 변화는 없었다. 결 론 : 이상의 다시설 개방 임상 연구를 통해 리스페리돈은 정신분열병 환자에서 양성증상뿐만 아니라 음성증상 및 전반적인 증상에도 효과적인 것으로 사료된다. 보다 명확한 평가를 위해서는 다른 항정신병약물과의 이중맹검 연구가 필요할 것으로 생각되며, 또한 장기적 치료에 대한 평가도 함께 이루어져야 하겠다. Objective : The purpose of this study was to investigate the efficacy and safety of risperidone in the treatment of Korean schizophrenic patients. Method : This multicenter open study included 377 schizophrenic patients drawn from 39 university hospitals. After a wash-out period of 1 week, the schizophrenic patients were treated with risperidone for 8 weeks and evaluated at 5 points ; at baseline, and 1, 2, 4 and 8 weeks of treatment. The dose was increased from 2mg/day(1mg twice daily) to 6mg/day(3mg twice daily) during the first week and adjusted to a maximum of 16mg/day over the next 7 weeks according to the patient's clinical response. Medication to control extrapyramidal symptoms was permitted. The psychiatric and neurological status of the patients was assessed by PANSS, CGI, and ESRS scales. Results : 343(91%) of 377 patients completed the 8-week trial period. Clinical improvement, as defined by a 20% or more reduction in total PANSS score at end point, was shown by 81.3% of patients. The predictors of response to risperidone were associated older age, shorter duration of illness, fewer previous hospitalization. Risperidone had rapid onset of action ; a significant decrease of the total PANSS and three PANSS factor(positive, negative, general), and CGI was already noticed at the end of first week. For the ESRS, parkinsonism rating scores were significantly increased until week 4 comparing with baseline. Dystonia rating scores were significantly increased until week 1, and dyskinesia rating scores were not significantly changed during the study. Laboratory parameters including vital sign, EKG, hematological, and biochemical values showed no significant changes during the trial. Conclusions : This study suggests that risperidone is generally safe and effective against both the positive and negative symptoms in our group of patients.

The chemical components of radish buds were investigated during the growth stage. The vitamin C and total phenol contents were lowered after 4 days of early sprout growth, and were 22.19 and 4.99 mg%, respectively.These increased according to the growth time, showing the highest value on day 8, 25.85 and 17.87 mg%, respectively. However, these values decreased around day 12, which seemed to be the bud end point. The major free sugar component of the radish buds was glucose, showinged the highest content on day 8. The total organic acid content gradually increased as the growth proceeded. The detected oxalic acid content was only small on day 8. During the early growth stage, the total and essential amino acids contents were 3,020~3,575 and 1,206~1,499 mg, respectively. These contents tended to decrease with growth time. Glutamic acid, aspartic acid and alanine were the major amino acid components (39%).

The erosion characteristics of heat exchanger tube submerged in bubbling fluidized bed were investigated in a cold model reactor which had a cross sectional area of 0.15×0.2m and a height of 1m. The bed materials were two different sizes of river sand with the average diameter of 0.731 and 1.243mm. The static bed height was 45cm. The wear specimens were made of acrylic tube with a diameter of 24.6mm and a length of 150mm. Test tubes were located inside the bed with three tubes in a low at 15, 30, 45cm and with a single tube at 60cm above distributor plate. Test was performed with the variation of fluidization velocity of 1.2 to 2.2m/s for 100 hours per set. The test was performed ti investigate the effects of fluidization velocity, array of tubes, distance above distributor plate on the erosion rate, and the erosion trend of tube surface with radial and axial direction. The results showed that the erosion rate increases with fluidization velocity and with distance above the distributor plate. The erosion was severe at the tube located in the splash zone of 60cm above the distributor. the trend with radial direction showed severe erosion at the 4-8 o'clock clockwise compared to other areas, especially 5 and 7 o'clock clockwise.

콘크리트 원주형 공시체의 크기에 따른 압축강도의 감소현상은 많은 관심을 받아 왔으나, 지금까지도 이에 대해 제시된 모델식이 드문 실정이다. 기존의 연구결과에 의하면 콘크리트의 강도는 부재의 크기가 증가할수록 감소하며 그 파괴거동을 규명하기 위해서는 비선형 파괴역학 이론을 적용해야 함을 알 수 있다. 표준형 및 비표준형 원주형 공시체의 크기에 따른 압축강도의 변화를 파괴역학 이론에 따라 연구하고 실용적인 예측 모델식이 제시된 바 있지만 콘크리트의 강도수준에 따른 파괴메카니즘의 차이를 고려한 관계식은 전무한 상황이다. 본 논문에서는 강도수준을 고려한 압축강도 예측 모델식을 제시한다. 또한, 파괴역학 이론으로 설명되지 않는 부분은 일반적인 단순 지수관계식을 이용하여 보다 일반화된 크기 효과에 대한 모델식을 제시하였다. The reduction phenomena of concrete compressive strength with the size of cylinders ave been extensively investigated, but till now the adequate analysis technique is not fixed. The existing research results show that the bigger the member size, the smaller the strength. This means the nonlinear fracture mechanics theory is needed in order to analyze the fracture behaviors of concrete and size effect. There is a few model equations that is to predict size effect of compressive strength of standard and non-standard cylindrical specimen. However, theses equations did not considered difference of fracturing mechanism which depends on strength level. In this paper, model equations to predict compressive strength of concrete considering size effect and strength level are suggested. Furthermore, the remain part that is not explained by means of nonlinear fracture mechanics, is simplified by an equation of simple exponential form. The size effect model suggested in this paper shows good prediction compared with existing test data of various concrete strength level.

Detection of thyroid stimulating hormone receptor(TSHR) autoantibodies has clinical value in establishing the diagnosis of Graves ' disease, and in predicting its clinical course with high sensitivity and high specificity. Especially, TBII using radioreceptor assay has been widely used. Recently, for detecting thyroid stimulating antibody(TSAb), a sensitive method using human TSH receptor-transfected Chinese Hamster Ovary(CHO) cells has been developed and clinically used. The aims of this study are to determine the change and discrepancy of 2 TSHR autoantibodics in clinical course and to evaluate the correlation between 2 autoantibodies. We measured TSAb and TBII in 30 newly diagnosed and untreated patients and in 73 previously diagnosed as Graves ' disease and treated with antithyroid drug. Also we compared the changes of the antibodies in clinical course and correlation between 2 antibodies. Thes results are summarized follows. 1. In newly diagnosed patients, all of the 30 patients had positive TBII and/or TSAb. None of them had negative TBII and negative TSAb. And in newly diagnosed patients, mean TBII and mean TSAb values are 46.8% and 361%, respectively. In 73 treated patients mean values are 18. 7% and 196% each other. Therefore, newly diagnosed group has significant greater TBII and TSAb than antithyroid drug-treated group. 2. TBII was significantly different between euthyroid group and thyrotoxic group in antithyroid drug-treated patients, but TSAb was not. 3. TBII was sequentially decreased as increased medication duration, but TSAb was not shown sequential decrease as increased medication duration. 4. There was significant negative correlation between cumulative doses of antithyroid drug and TBII, but no significant correlation between cumulative doses and TSAb. 6. There was significant positive correlation between TBII and TSAb in total patients group and in antithyroid drug medication group, but not in newly diagnosed group. In conclusion, in Graves ' disease patients, detection of TSHR antibodies are clinical values in establishing the diagnosis and prediction of clinical course. A method detecting TSAb using hTSHR-CHO cells should be further studied for standardization of measurement, and for detecting the changes of TSAb in clinical course, long-term follow-up of patients are important.
