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.

金慶麟,金榮煥,崔光善 慶北大學校 1989 論文集 Vol.47 No.-

The effects of group goal, group age and group relationship on manager's reward allocation processes were examined through two experiments. The subject's task was to decide annual salary increase for subordinates with varied performance appraisals. Exp. Ⅰ was designed to examine how the choice of the reward allocation principles varied according to group age and subject's goal which was either to increase subordinate's performance or to promote subordinate's teamwork. Exp. Ⅱ was designed to examine how the choice of the reward allocation principles varied according to group age in- and out group distribution. Major results were as follows., (a) Subjects of young group were inclined to choose a relative equity norm and a relative equality norm, respectively. (b) Subjects of old group were inclined to choose the equality principle in each goal. (c) One of the two distribution principle(equity or equality) for in- and out group reward distribution were chosen by subjects of young group. (d) For subordinates of in- and out group, the equality principle was chosen more frequently than the equity principle by subjects of old group. These results were discussed from the point of manger's reward allocation process as managerial behavior. It was concluded that manager's choice of reward allocation principle was determined by manager's manegerial strategy.

김지혜,고선규,고효정,권영아,김성환,김재경,김태은,박재우,서민영,송영란,이인수,김도관 大韓神經精神醫學會 2003 신경정신의학 Vol.42 No.2

Objectives : We examined the effects of INM 176 (K-l107) compared with placebo on the cognitive functions of 92 old aged subjects with cognitive impairment. Methods : This was a prospective, 12 week, double-blind, Placebo-controlled clinical trial. The elderly who achieved a score of less than 25 points on the K-MMSE or showed a high risk of Alzheimer's disease from the 7-Minute Neurocognitive Screening Battery were considered to have objective impairment and were selected as subjects for this study. The subjects were randomized to placebo or INM 176 group. The outcome measures were from the Alzheimer's Disease Assessment Scale-cognitive subscale (ADAS-Cog), the Instrumental Activities ofDaily Living (IADL) and the Korean Geriatric Depression Scale (KGDS) and two kinds of computerized priming tests. After setting the total error score in the Alzheimer's Disease Assessment Scale-Cognitive section (ADAS-cog) as the repeated measurement factor, an analysis of variance of the combined factor design was done between the placebo and INM 176 group. Results : The interaction effect of time (pre- and post-trial) and group (placebo and INM 176 group) was significant in the analysis of the ADAS-cog's total error score. The INM 176 group's total error score in the ADAS-cog decreased significantly (p<0.01), whereas the placebo group showed a slight increase. The mean changes in IADL and GDS from baseline scores favored in the INM 176 group than in the placebo group. Outcome changes ofADAS-cog, IADL, KGDS scores during the 12 week clinical trail ofINM 176 and placebo demonstrated favorable responses in the INM176 administered group. Conclusions : This is a preliminary clinical trial result of INM176 as a memory pill. Based on these results, INM176 may be a candidate molecule for the improvement of cognitive functions, including memory, Further clinical trial should demonstrate its efficacy.

In the previous study, we suggested a new concept, named as GRSS(Gel-Route Stabilization/Solidification) and investigated a material system applicable to volatile radioactive waste, a reaction condition and chemical limitations. From these results, this paper investigated the effect of some additives, which have been considered as the major component of ceramic waste forms(apatite and sodium zirconium phosphate), on the thermal stability and chemical durability. The Si-P system with Ca at appropriate composition shows good thermal stability but low chemical durability while the Si-P system with Zr shows relatively low thermal stability but relatively high chemical durability.

This paper attempts to review and trace back to, based on the data collected during visits of Japanese universities and research institutes, the organizational characteristics, the structures of curricula and study trends, with regard to the fields of social sciences, especially economics and business administration. One of the most conspicuous characteristics observed in academic organizations was Tsukuba university's system whose academic institution was organized around academic grouping, academic genealogy, and specialty: particularly social economic planning belonged to the genealogy of social engineering, in light of its characteristics in term of curriculum, seems to meet the contemporary need. There found two speciality areas in the Department of Social Engineering at the Graduate School: one is the concentration on Mathematical Planning and the other Management Engineering. Considering that its academic goal is tosys tematically and empirically analyze the human behaviors, and to take interdi-sci plinary approach through a policy-oriented system in doing so, it reflects one of the true natures of the academic trend. Their curricula appear to emphasize on analytical methods under uncertainty, application of mathematical planning techniques, system simulation, and information system design and its application, in the area of economics and business administration. Physical education is believed to require modernized facilities and equipments for its record-breaking and technical enhancement, and so increased investment in physical facilities and policy considerations for the training of physical educators are necessary.

This study was to investigate the effects on hematological indices and heinz body formation in various intensity, Male Sprague-Dawley rats were randomly divided into the control group, the low-intensity exercise group, nigh-intensity exercise group (n=7 in each group). Animals of the low-intensity exercise groups were put on exercise 30 min per 1 day, 5 days per week for 6-weeks. Animals of the high-intensity exercise groups were put on exercise 120 min per 1 day, 5 days per week for 6-weeks. Red blood cell count (RBC), hemoglobin (Hgb), hematocrit (Hct), mean ceil volume (MCV), mean hemoglobin corpuscular (MCH), mean hemoglobin corpuscular concentration (MCHC) were analyzed in automated hematology analyzer (ABX Hematology MICROS 60) from 10㎕ of whole blood. Erythrocyte morphology were evaluated in super vital (Brilliant cresyl blue stain) stained blood films. In the present results, Hg, MCHC in the high-intensity exercise group was significantly decreased compared with the different exercise intensity and the control group. MCV in the high-intensity exercise group was significantly increased compared with the different exercise intensity end the control group. Heinz body formation in the high-intensity exercise group was significantly increased compared with the different exercise intensity and the control group. In the present study, it can be suggested that intensity of exercise can influence hematological variables and heinz body formation. These findings suggest that high intensity exercise induces oxidative damage to erythrocyte.
