The purpose of this study was to develop extrusion process of fresh potato and to study the effects of extrusion condition on the pasting properties of extruded potato products. The blend of pressed potato and wheat flour and pressed potatoes were extruded at different die exit temperatures (110-160℃) and screw speed of 100 rpm using a twin-screw extruder with conveying, high and low shear screw configuration. The viscosity-related parameters, such as peak viscosity, through, final viscosity, peak time, and pasting temperature of the feed materials and extruded products, were studied using a rapid visco analyzer (RVA). Their water solubility index (WSI) and water absorption index (WAI) were also studied. The peak viscosity, through, final viscosity, and peak time of pressed potato extrudates and potato-wheat flour mixture extrudates decreased as die exit temperature increased. The WSI and WAI of potato products increased as die exit temperature increased. When high shear screw configuration was used, the values of viscosity-related parameters were lower than those when low shear screw configuration was used. The potato-wheat flour mixture products obtained different degrees of depolymerization from fresh potatoes and wheat flour depending on die exit temperature and screw configuration.

Geum-Won dynasty is the era which totalized the every medical attainments of before Song dynasty and appeared some medical practioners who found new medical theory based upon this, and is important time for various developments of the oriental medical theory. At this time of the era, the representative practioners are called the four noted physician of Geum-Won dynasty. Jang Won-So who influenced the formation of the theory of the four noted physician of Geum-Won dynasty, originated new theory by joining the theory of 「Nae-Gyung」 with his own medical experience. The results can be summarized as follows after studying his life and idea of medicine. 1. Jang Won-So, courtesy name is Gyeol-Go, came from Yeog-Joo and it is unknown that when he was born and dead, but he lived in 11C. At 27, after failed in a Jin-Sa examination, he started medical study, and widely spreaded his medical art by healing the Yoo Wan-So's Sang-Han disease. 2. There are many Jang Won-So's writings, such as 「Eui-Hag-Gye-Won」 which is the condensation of his idea of medicine, 「Jin-Joo-Nang」 which is greatly contributed to development of Herbology, 「Jang-Boo-Pyo-Bon-Han-Yeol-Heol-Sil-Yong-Yag-Sig」 which is the sample of Jang-Boo-Byun-Jeung-Lon-Chi, and 「Yag-Joo-Nan-Gyung」 「Gyeol-Go-Ga-Jin」 「Gyeol-Go-Joo-Sug-Hwa-Mag-Myeol」 「Gyeol-Go-Bon-Cho」 「San-Yog-Bo-Sang-Bang」 which are known do not existing. 3. Jang Won-So's study about Jang-Boo-Byun-Jeung was influenced by 「Nae-Gyung」 「Jung-Jang-Gyung」 「So-A-Yag-Jeung-Jig-Gyeol」 etc. and outline by Han-Yel-Heo-Sil and the change and prognosis of the state of disease can be decided by Saeng-Sa-Yeong-Soon, so he contribute to development of Jang-Boo-Byun-Jeung-Lon-Chi of posterity. 4. Jang Won-So succeeded and develope the theory of the herbs of Oh-Jang-Go-Yog-Bo-Sa and about Ki-Mi-Seung-Gang-Boo-Chim etc. appeared on 「Nae-Gyung」, especially invented such as Kwi-Gyung-Lon, In-Gyeung-Bo-Sa-Seol, Jang Boo-Pyo-Bon-Yag-Sig and he enriched the content of pharmacological theory, so he motivated various development of herbalogical theory. 5. Jang Won-So's idea of On-Yang-Bi-Wi directly influence Lee Go's assertion of Bi-Wi-Lon, idea of Go-Geum-I-Gue-Seol presented theological basis of posterior medical practioners formation of prescription, so the way of drug usage greatly developed. 6. Jang Won-So's theory of the Jang-Boo-Byun-Jeung and herbology directly influenced to Lee Go, Wnag Ho-Go, Na Chen-Ik, Jang Byeok etc. so he became the father of Yeog-Soo class and indirectly influenced to Seol Gi, Jo Hen-Ga, Jang Gae-Bin, Lee Jung-Jae etc. of Myeng dynasty, so the On-Bo class has been formed. Like this, because, his idea of medicine developed at various aspect and greatly influenced to posterity, Lee Si-Jin said "Since the emergency of 「Nae-Gyung」, Jang Won-So is the only man who greatly enhance medical principle." so it is clear that this is not unfounded expression at all.

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 preparation of high purity silicon by the hydrogen reduction of sicl_4 which producted from the chlorination of commercial ferrosilicon was carried out. The chlorination rates and reaction ratio of ferrosilicon were increased with inoreasing of temperature and Cl_2 flow rate. The optimum Cl_2 flow rate and particle size of ferrosilicon was about 50ml/min and 30-40mesh, respectively. Reaction rate and reaction ratio were increased in the presence of NiCl_2, but CaCl_2, znCl_2, Cu powder and Cu-turnings were acted as an acticatalystic effects. By the addition of 10% NiCl_2 catalysis at 250℃, 66% reaction ratio for four hours was obtained. Silicon chlorides products were purified by the combination of the fractional distillation and silica gel adsorption techniques, and, using these purification techniques, all metallic and nonmetallic impurities were eliminated to unit ppm purified SiCl_4 was reduced in a graphite tube by hydrogen in the temperature range of 900-1200℃, The yields of the silicon products were increased with increasing of temperature and H_2/SiCl_4 mole ratio, and yields at 1100℃ and 1200℃ with mole ratio of 50 was 30% and 43%, respectively. Growth morphologies of silicon crystal were fine needle or cobweblike growth up to 1100℃ and coarse needle or sawtoothlike at 1200℃. These growth morphologies were little changed with precipitation substrates. The purity of silicon product which was analyzed after etching of HF and hydrochloric acid was higher than 99.99%.
