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.

Many construction companies have developed many kinds of information system to integrate the information created. in the phase of planning, design, procurement, construction, and maintenance of construction project. However, the previous researches for the state of applying information technologies and the efforts of the analysis of the present information system launched. in domestic construction industry is very rare. 1here also has been short of research on the construction decision-making support theory in construction business and industry. Hence this paper would contribute in identifying the state of information technologies and the theory of decision-making support of the information system in general construction company, and propose the characteristic model on the information system for the construction decision-making support. The model consists of the two dimensions; (1) organizational hierarchy (2) data analyzing technology. This research, especially, can be expected. to initiate the discussion on framework for understanding the construction decision-making support system in construction industry. The model is not a practical methodology, but a window that offers a new perspective on sources of information system in each construction company, and thus can provide a clue of the useful guide to construction information system development.

This studies were carried out to obtain the basic data for rationalizion and modernization of management on horticultural crops in vinyl house. It was investigated from late December to January on micro-meteorology of Kimhae, Sooncheon and Jinju vinyl houses where are producing vegetable crops in vinyl house of a large area. Air temperature in Kimhae vinyl house was heated with hot wind by oil burner. In the others it was kept warm more than 10℃ with only covering materials, but there may have some damages of high temperature and the instabilized production by abnormal climate. Humidity control in Kimhae was suitable comparatively for vegetable crops. In the others districts, however, it was maintained high relative humidity more than 90%. Therefore, cucumber in Sooncheon vinyl house was tender to take a disease and in Jinju it was attacked with powdery mildew. Soil temperatures in Kimbae, Sooncheon and Jinju vinyl houses were kept warm to cultivate crops. Light transmission rates of solar radiation in all vinyl houses were 50% of outdoor. Therefore, it must make an effort to develop the materials and rationalize the management in order to increase it in that places. CO_2 concentration should be increase in Kimhae as minimum CO_2 concentration was decreased to 140 ppm. In the others it was kept more than 250 ppm because of putted straw under soil to protect the cold soil temperature.

본 연구에서는 ZnTPP와 MgTPP를 도우핑한 폴리이미드의 과악적 성질을 UV spectrum과 emission spectrum을 이용하여 조사하였다. Tetraphenylporphyrin-zinc (ZnTPP)와 Tetraphenyl-porphyrin-magnesium (MgTPP)는 전하이동현상을 보였다. 폴리이미드와 폴피린관련 자외흡수피크에서 red-shift를 관찰할 수 있었다. 이는 폴리이미드의 이미드와 폴피린에 포함된 금속 물질과의 전하이동착체의 형성때문으로 설명할 수 있다. In this research, we fabricated metalloporphyrin doped polymides(PI) and characterized them with ultraviolet spectrophotometer and emission spectrophotometer. Tetraphenylporphyrin-zinc-doped and Tetraphenylporphyrin-magnesium-doped PIs showed charge transfer phenomena. Red-shift was obseved in polyimide and porphyrin related bands at the same time. This phenomena can be explained that charge transfer complex(CTC) formed between imide group of PI and metal in the porphyrin.

Grain boundary dissolution and separation of hydroxyapatite (HA) in distilled water were investigated For the preparation of HA ceramics, a laboratory synthesized HA powder with different Ca/P molar ratio was used. After preparing powder compacts, the specimens were sintered at 1200℃ for 2h in air with under moisture protection. Microstructural degradation related to the grain boundary dissolution could be induced by microstructures and composition of HA ceramics.

경험적 최우 학습 규칙을 이용한 다층 퍼셉트론의 성능 향상 방안

이종국,이재욱 동서대학교 1995 동서논문집 Vol.1 No.1

We reports on a probabilistics method that can be used to train a multilayer perceptron networks. The alternative method is based on the criterion of empirical maximum likelihood rather than the sum-of-squares cost function used in the conventional BP. In tests, the EML algorithm converges to a near optimum solution, without increasing the computational complexity. Moreover the number of iterations required for convergence is open landscape produced by EML is simpler than BP. Hence this leads to a more efficient learning rule for multilayer networks.
