Kim, Byoung Soo Chungcheong Mathematical Society 2014 충청수학회지 Vol.27 No.2

Cameron and Storvick discovered a change of scale formula for Wiener integral of functionals in a Banach algebra $\mathcal{S}$ on classical Wiener space. We express the analytic Feynman integral of cylinder function as a limit of Wiener integrals. Moreover we obtain the same change of scale formula as Cameron and Storvick's result for Wiener integral of cylinder function. Our result cover a restricted version of the change of scale formula by Kim.

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.

Background : Adapalene is a new synthetic naphtholic acid derivative with potent retinoid and antiinflammatory properties, developed for the topical treatment of acne vulgaris. Objective : This study was designed to compare the efficacy and safety of 0.1% adapalene gel with tretinoin cream(0.025% and 0.05%) in the treatment of grade I to V facial acne vulgaris. Methods : Forty acne patient volunteers were enrolled in this investigatormasked, left-right comparison, randomized, controlled, intraindividual study. 0.1% adapalene gel and tretinoin cream(0.025% or 0.05%) were applied once a day to one halfface by the volunteers for 30 consecutive days. Efficacy and cutaneous tolerance were accessed at baseline and week 1, 2, 3, and 4. Efficacy was determined by investigator counts of inflammatory papules and pustules, and non-inflammatory open and closed comedones, as well as global improvement. Clinical signs(erythema, desquamation, dryness) and subjective symptoms(pruritus, burning) were evaluated and scored weekly. Result : 0.1% Adapalene gel was more effective in treating acne lesions than tretinoin cream(p<0.05). Cutaneous side effect was limited to a mild retinoid dermatitis occurring in all treatment groups. However, patients treated with adapalene gel tolerated this therapy significantly better than those treated with tretinoin cream. Conclusion : 0.1% adapalene gel applied once daily was significantly more effective in reducing acne lesions and was better tolerated than tretinoin cream in the treatment of acne vulgaris.

To estimate the change of riverbed geography by the operation of movable weir, two-dimensional RMA-2 and SED-2D were used in this study. Hydraulic elements like flowrate or depth were simulated by RMA-2 and the change of riverbed geography according to sediment transport was simulated by SED-2D. Suktop stream was chosen as a project river for the simulation. Under the condition of 50-year rainfall frequency, the estimated flood of Suktop was 123cms. At the points of movable weir the simulation results showed that the difference of high water level from the result of HEC-RAS was less than 0.64m. And the difference of water velocity was less than 0.21m/sec. Based on the sediment simulation by SED-2D, predicted riverbed elevation was 29.70-30.22m at the point of ST1 and 28.26~28.82m at the point of ST2. Measured riverbed elevation was 29.70-30.16m, 28.28-28.69m, respectively. So, the predicted elevations are closely similar to the measured elevation. At the point of ST1, sediment transport simulation results showed that erosion of riverbed was predicted by the operation of movable weir. This erosion was ranged up to 200m upstream and the riverbed would be eroded away as much as 0.07m for one year. At the point of ST2, upstream of movable weir would be eroded and the erosion depth was estimated 0.261m. The erosion was higher at the point of movable weir and the erosion depth was estimated 0.310m. But the sediment would be deposit downstream of the movable weir. SED-2D followed by RMA-2 is well applicable to the stream which has movable weirs and can estimate not only hydraulic parameters such as flowrate or depth but also riverbed elevation change caused by erosion or deposit of fluvial sediment.
