The purpose of this study was to investigate the effects of detraining and retraining on serum lipid and hormones in soccer players. Subjects were seven male high-school soccer players. V˙O_2max was determined for each subjects by administering a treadmill test(initial speed: 90m/min, grade: 5%, increasing speed per 3 min: 30m/min). Serum lipid(T-C, TG, HDL-C LDL-C) and hormones(epinephrine, norepinephrine, growth hormones, cortisol) were assayed pre and post detraining in 10, 20, 30 days after retraining. The repeated ANOVA was used to determine significant differences. The 0.05 level of significance was as critical level for the study. The results of the study were as follows: 1. V˙O_2max(ml/min) were 3576.3±204.2ml/min pre detraining, 3234.1±198.9 ml/min post detraining. There are significant(p<.05) difference between pre and post detraining. In 10, 20, 30 days after retraining, V˙O_2max(ml/min) were 3601.4±170.9 ml/min. There were significantly(p<.05) increased in retraining periods. 2. V˙O_2max(ml/kg/min) were significantly(p<.05) decreased from 62.3±2.9 ml/kg/min to 55.9±4.7 ml/kg/min in detraining. In 10, 20, 30 days after retraining, V˙O_2max(ml/kg/min) were 62.4±3.4ml/kg/min, 62.7±2.3ml.kg/min, 67.3±7.2ml/kg/min respectively. There were significantly(p<.05) increased in retraining periods. 3. T-C were significantly (p<.05) increased from 166.6±8.5mg/dl to 175.3±10.3 mg/dl in detraining. In 10, 20, 30 days after retraining, T-C were 160.1± 3.2mg/dl, 156.7±3.7mg/dl, 140.3±9.0mg/dl. There were significantly(p<.05) decreased in retraining periods. 4. HDL-C were 61.4±6.6mg/di pre detraining, 5.3±6.6mg/dl post detraining. There are significant(p<.05) difference between pre and post detraining. In 10, 20, 30 days after retraining, HDL-C were 56.9±7.1mg/dl, 56.4±9.2mg/dl, 57.7±9.1mg/dl respectively. There were no significant difference in retraining periods. 5. The hormones(epinephrine. norepinephrine, growth hormone, cortisol) were changed as same patterns. Epinephrine were 26.0±7.0[g/ml pre detraining, 24.6±3.2pg/ml post detraining. In 10, 20, 30 days after retraining, epinephrine were 26.9±5.6pg/ml, 30.6±6.2pg/ml, 29.4±5.6pg/ml respectively. There were no significant difference in retraining periods. In conclusion, HDL-C, epinephrine, norepinephrine, growth hormone and cortisol were decreased, T-C, LDL-C and TG were increased in detraining. But HDL-C, epinephrine, norepinephrine, growth hormone and cortisol were increased, T-C, LDL-C and TG were decreased in retraining.

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.

Our communities have been exposed to polluted air. Polluted air could cause the serious injury such as respirational impediment, disease and so on, and the air pollution could be most serious problem in our life. Unfortunately, we didn't have consider these problems seriously, and we had make no solutions for these problems. Although the concentration of indoor and outdoor didn't show the high values, VOCs existed in indoor and outdoor environment. The indoor concentration was more higher concentration than the outdoor concentration, that indicated the indoor environment was more polluted. This study showed that the investigation of a continuous environment polluted were needed.

정철정,이종훈 한국운동역학회 1996 한국운동역학회지 Vol.6 No.1

본 연구의 목적은 100m 달리기 구간에서 일어나는 운동학적 변인들을 알아보고자 최대 속대 구간과 마지막 구간을 설정하여 시간 요인, 속도 요인, 거리 요인으로 나누어 분석하였다. 그 결과 최대속도 구간의 평균 속도는 9.70m/s, 마지막 구간의 평균 속도는 8.37m/s로 9.96%가 감속되었다. 또한 최대 속도 간간에서는 평균 지지시간은 0.11초, 마지막 구간에서는 0.13초로 속도가 감소할수록 지지시간이 증가함을 보였다. 그리고 최대 속대 구간에서 마지막 구간으로 평균속도가 9.96% 감소하였으며, 보속은 7.80%가 적어졌다. 한편 신장과 하지장간은 밀접한 상관이 있는 것으로 나타났으나 보속과 보폭은 역상관관계로 나타났다. 보폭은 최대 속도 구간과 마지막 구간에서 차이가 없었으며, 비행시간과 평균 속도와는 상관이 없는 것으로 나타났다. The purpose of this study is to know the kinematical factors happening in 100m running phase. Represenfative 10 high school runners in Seoul are studied, using the maxmum speed phase and final phase. In addition, 3 factors such as time, speed, distanced, are analysed by comparison. 1. The average speed in maximum speed phase is 9.70m/s and the average speed in final phase is 8.37m/s, which is the 9.96% decrease of the speed. 2. The average support time in maximum speed phase is 0.11(s) and in final phase 0.13(s). This shows that the more the speed decreases the more the support time increases. This is an important factor in downing the record of 100m running. 3. When the speed comes down in 9.96% of the average speed from the maxmum speed phase to final phase, the stride frequency decreases by 7.8%. 4. Height has a very close relation with leg length, having 0.88 correlation of coefficient. Stride frequency has a anticorrelation coefficient. 5. There is little difference between the stride lenghts in the maxmum speed phase and finnal phase. 6. There is no significant differences between the flight time and the average speed.

Ice cream is a vastly consumed food enjoyed by a wide range of people. Therefore, it is easily accessible and amounts to hundreds of its kind. Ice cream is a ready-made food which could be served without undergoing cooking process and thus putting weight on its hygienic condition. And so we set out to conduct some research on the number of E-coli bactria contained in commercially sold ice creams. We applied Lactose broth method along with Desoxycholate agar method which enables us to verify the existence of E-coli bacteria and how much is contained. We focused our research on soft ice creams and aimed to seek out the degree to which they were contaminated by E-coli bacteria. 4 major distributors of soft ice cream out of 5 didn't meet the maximum allowance of E coli bacteria to be found. The number of general bacteria observed per 1 ㎖ of specimen must be held at less than 100,000, and this wasn't violated by any of the companies' samples. Yet on E-coli testing, all of K, L, B and M companies' samples respectively exceeded the permitted limits of bacteria to be detected.
