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.

This paper deals with the ultrasonic vibration cutting for the precision machining of aluminum alloy. When the ultrasonic vibration is applied on the tool, the cutting tool makes periodical contact with workpiece. And, the cutting is performed by vibrating impact force while the cutting tool contacts the workpiece. In this paper, the horn of ultrasonic vibration system were designed and manufactured, to compare the ultrasonic vibration cutting with the conventional cutting, the machined surface roughness of aluminum alloy in turning were experimentally measured. The experiments revealed that the ultrasonic vibration cutting had the best surface roughness than the conventional cutting under the same cutting condition.

The reduction of working hour would have direct effects on the korean industries, According to the study results, working hour per week is 48 hours which include 44 legal working hours and extended working hours. As a result, korean working hours is even higher than advanced countries. If the working hour is reduced to the hour of the advanced countries. real cost of labor increases would be lager than capital intensive industries. The results show that large damage would come from trading with Japan and the US. According to results. The reduction of working hour would affect increasing cost of labor and be a burden on the korean industries. Therefore, a more aggressive labor policies from government are needed in order to lower the burden.

Employment of foreign workers has been a common issue in the advanced countries for a long time period. In Korea, the issue emerged for the first time when Korea imported mining workers in 1991. Taking into consideration many hot debates by industrial, labor, and political sectors about the effect of overseas workers' employment on the society, it is a very delicate and important matter, not one to be considered simply economically. Since the employment of foreign workers in the industrial production sector has become a reality, which we can not deny or refuse, without dramatic change of the labor related policy, or preparaton of a fundamental problem solving method, the inflow of those workers will continue, and will cause a lot of social problem. Therefore, more active approaches mentioned below, far from current passive and temporary remedy, are required to solve the problem. First, in case the authorities concerned permits a partial import of foreign workers, our government should provide the foreign workers with the same status and treatment as local workers receive, but the permit should be given to the foreign workers only for a short term period. Second, the government should expand the present technical trainee program aiming at relieving the shortage of labor supply, and at the same time actively prevent employers from hiring illegal foreign workers. Third, even though a partial supply of foreign workers is permitted, the government should prepare for ways against any negative effect caused by the import. To do this, government to consider policies like fun-allotment or deposition systerm. Fourth, the government needs to consider installing a new agency to be in charge of and effectivelt manage foreign workers' employment on the base of the prospect of local labor supply and demand.
