Deltamethrin의 단감 재배기간중 살포횟수 및 처리시기에 따른 잔류수준을 시험하여 다음과 같은 결과를 얻었다. 1. Deltamethrin의 잔류분석 회수율은 단감시료에 대해 0.1ppm과 1.0ppm에서 각각 평균 90.20%, 90.73%를 보였고 검출한계는 0.01ppm이었다. 2. Deltamethrin의 단감에서의 잔류는 Mills 등의 방법으로 분석한 결과 수확 3일전 6회 처리구에서만 0.16ppm으로 잔류 허용기준을 초과하였고 이로 미루어 deltamethrin의 단감중 안전사용은 수확 3일전 5회 이내의 사용으로 추천할 수 있었다. The effects of application number on the persistence of deltamethrin in sweet persimmons was analyzed. Deltamethrin EC(1%) was sprayed on the sweet persimmon trees at regular intervals (400 L/10a, 1,000 times diluted deltamethrin EC was sprayed on 60th, 45th, 30th, 15th, 7th, 3rd days before harvest). The procedure of residue analysis was based on the multiresidue analytical method using a polarized acetonitrile solution as the extracting solvent. Residue of deltamethrin were determined by alternate eluate (acetonitrile, hexane, dichloromethane 1.5 : 48.5 : 50 v/v) from the Florisil column to gas chromatographic analysis (ECD). Residue level of deltamethrin in sweet persimmons were proved to 0.16 ppm when the deltamethrin EC (1%) was sprayed 3 days before harvest. The recoveries were above 90% in spiked sweet persimmon samples, regardless of concentration.

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 purpose of this study was to understand how senior high school teachers who participate in leisure activities experience leisure constraints. For analyzing this, three teachers who have experienced a leisure activity for more than two years, and other three teachers who have experienced it less than a year were participated in this study. They were consisted of three male and three female teachers. The results were as follows. Firstly, The degree of leisure constraint was different from the participants` leisure careers. The teachers participating leisure activities under a year are absented by outer circumstances, or psychological changes. On the other hand, the teachers who have experienced them for more than two years, or are in the level of recreational specialization didn`t absent in spite of their leisure constraints. Secondly, the participants who joined in sports activities were affected by intrinsic and interpersonal leisure constraints, and the participants who joined in the area of non-sports activities were affected by structural constraints. Thirdly, non-sports activities were closely connected with personal hobbies. In this respect, they could continue their leisure activities even though they need a large amount of money and their satisfaction level was also high. Fourthly, in case of emerging leisure constraints like child care or housework, women participants were sensitively affected rather than men participants.

The purpose of this study is to measure the correlation between leisure activities of women and the job opportunities in their respective career field based on ground theory. Through this process, the study will discover the potential benefits of leisure activities by understanding the positive and negative effect that exist in changing occupations by the level of leisure activities. The discovering of potential benefits of leisure activity will allow an individual to re-examine the purpose of life and will reconstruct the meaning of leisure activities in individual’s life. Under these condition, two conclusions were obtained. First the paradigm of the role of leisure activity in the process of job re-search as a women fitness trainer’s discontinuity of her career can be shown as six components according to the ground theory. Women’s career discontinuity in a causal condition starts of by fitness training as leisure activity leading to navigate and re-search as a central phenomenon. However, as an intervening condition where job re-research is used as a constraint factors, fitness training appeals as an interaction strategy that leads to a negative effect of becoming professional fitness trainer. Second, through the process of job re-search of women’s career discontinuity, the study analyzes the role of leisure activity found that it leads to positive attitude and gain confidence in their lives. The study showed that housewives who sacrifice themselves for their family are also needing to enjoy leisure time as a member of the family to be productive in society. Also career discontinuity woman needs opportunity and interest to enjoy their leisure time.
