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.

Vibration-controlled concrete has been developed by using various concrete mixtures, such as latex, rubber powders, plastic resins and polystyrene(styrofoam). As part of the recycling research of obsolete aged <tires and plastic> materials, vibration-reducing mixtures are used for 10 concrete panels above 200 ㎏/㎠ in uniaxial compressive strength. Laboratory test and open space test have been carried out for the analysis of the impact wave, of which data have been transferred by the FFT technique to comparatively investigate damping ratios of 10 concrete panels. According to wave propagation analysis on vibration- controlled concrete for this research, it can be concluded that Latex concrete has relatively larger damping ratios than those for noncontrolled normal concrete with similar compressive strength.

In modern society the negotiability of a bill should be guaranteed in order to carry out its native function. There are defence, the institution of the good faith purchase of a bill, and the separate rule of a bill action for it. Because of these institutions, the negotiability of the transactions of a bill is promoted. It's important to protect both the negotiability of a bill and the debtor of a bill. The harmony of interests between the creditor of a bill and the debtor of a bill is guaranteed under the law of Bill. The institution of the good faith purchase of a bill is to harmonize between the creditor of a bill and the debtor of a bill. In Korea the institution of the good faith purrchase of a bio originated from the institution of the good faith purchase of chattel historically. But the good faith purchase of a bill is easier than that of chattel based on Civil law. The conditions of the good faith purchase of a bill are as follows. Firstly a bill should be obtained by the method of the law of a Bill. Secondly the indorsement of a bill should be continued. Thirdly a bill should be acquired by a rightless person. Fourthly the purchaser of a bill should have no bad faith and gross negligence. Fifthly there should be personal economic interests in association with the purchase of a bill. In this thesis a writer is inclined to examine whether a bill is obtained from a rightless person or the good faith purchase of a bill is recognized in case of defect of purchase of a bill(eg.assignor's disability, rightless agency, defect of manifestation of intention)with the exception that an assignor is a rightless person. In this connection there are serious conflicts of theories for it. A writer supports the position to recognize the good faith purchase of a bill restricted a rightless person on the basis of interpretation of the current Law of a Bill, general provision of private law and realization of legal stability The system of this thesis is as follows. 1.Introduction. 2.The controversies concerning scope of defect. A writer briefly introduces legislative examples concerning the good faith purchase of a bill, analyzes the controversies concerning the scope of defect in Korea, Japan and Germany through theories and cases. 3.Conclusion A writer analyzes the basic background of controversies concerning the scope of defect, presents a legal interpretation and legislative opinion.

This research is aimed to study the change in design environment caused by being digitalized, to define the new concept and sphere in digital design, to find out the direct or indirect on design by the social and cultural changes resulted in informational technology and internet, and to find out the change and response in design world being brought about it. Powerful digital forms a new world and market. Internet world, a symbol of the power, changes the area, method, and the process of design. The unity of interior decoration and appliance caused by the digitalization of living space brings about that of interior decoration and production design. On account of the change of the electronic products resulted in the informational technology, product design area has been changed from the outward appearance of the design to the software design and the interface design of users. Converted from electronic publication to multimedia design and homepage design area, virtual design also faces the same problem. This phenomenon will also change design area. Banner advertisement, as a representative of new media, appears newly. Electronic newspaper, news broadcasting, radio, and magazine through Internet unite the existing printing media and mass media such as radio, TV. As a result, their respective characteristics disappear and design areas seem to be changed into Internet broadcasting which has equivalent position and method. This change will be much faster on account of the rapid development of information technology. But impersonality and inhumanity caused by digitalization is the problem which digital society and designers should solve together.
