Objectives : We evaluated the efficacy of ramosetron and ondansetron for preventing postoperative nausea and vomiting (PONV) in laparoscopic colectomy. Methods and Materials : Eighty patients who received laparoscopic colectomy were randomly divided into two groups: R group (ramosetron 0.1mg PO) and O group (ondansetron 4mg twice IV). Injection or oral medication was administered before the induction of anesthesia in each group. Injection was administered at the end of surgery in O group. General anesthesia was induced using propofol and rocuronium, and maintained with sevoflurane, remifentanil and air (FiO2 0.5), We investigated the incidences of PONV in each group by the Rhodes index of nausea, vomiting and retching (RINVR) at postoperative 6 and 24 hours. Results : The incidence of PONV was not different between group at each time points after surgery (at postoperative 6 hours: 20% in group R, 17.5% in group 0, at postoperative 24 hours; 12.5% in group R, 7.5% in group 0). There was no difference in the severity of PONV, satisfaction, rescue drug usage. Conclusion : Prophylactic therapy with ramosetron is as effective as conventional prophylactic therapy with ondansetron for preventing PONV in general anesthesia for laparoscopic colectomy.

This study was to investigate the depression of the aged parents perceived through the conflicts between the aged parents and their adult children. The subjects of the study were 469 old parents, consisted of 234 male and 235 female over 60 years old lives in Kwangju. The datas were analysed by frequency, percentage, mean, standard deviation, oneway ANOVA, t test, Duncan's test and multiple regression using SAS program and the results are as follows. 1) In the conflict between the aged parents and their adult children which the aged parents perceive, the mean values are 32.54 in the case of old father and 34.26 in old mother from the average point. The average values of the depression the aged parents perceive are 26.03 and 28.35 each in old father and old mother and show the level of depression over the middle value. 2) The background variables which show the significant differences of the conflict between the aged parents and their adult children are marital status, age, education, pocket money, health and activity of the aged parents. 3) The background variables which show the significant difference in the depression the aged parents perceive are marital atatus, education, pocket money, health, activity, support type and occupation of the aged parents. 4) The depression and conflict between the aged parents and their adult children show high correlations and the greatest variable as the effect of conflict on the depression is emotional conflict. In addition, significant difference is shown depending on health, value and economic conflict and its explanatory power is 50%.

In the elderly population, there is a strong relationship between cognition and the level of physical activity. The purpose of this study was to evaluate cognitive function and activity level of daily living and to investigate correlation between Mini-Mental State Examination(MMSE), and Functional Independent Measure(FIM) in elderly with Alzheimer's dementia. Of the 15 subjects enrolled in this study, sixties and seventies were each 26.7%, and eighties was 46.7%. MMSE mean scores was 15.40±4.69, and FIM mean scores was 87.53±7.79. The scores of 'registration memory' item of MMSE was highest level(100%) but, the scores of 'recall' item was lowest level(11.11%). In MMSE and FIM, there were no significant difference by age (P=0.185, P=0.329). MMSE-FIM scores was significantly correlated (r=o.856).

This study was performed for effects of intervention of attention training, general cognitive training which influenced on the change of cognitive and performance with patients caused by Alzheimer's dementia. The cognitive training program was provided to experimental groups for 4 weeks(5 times a week) and no intervention was provided to control group. Measurements of pre, 2wks, post(4wks) and follow up(2wks, 4wks and 8wks) experiment were K-MMSE and ACL. The results of this study showed that in comparison of pre, 2wks, post and follow up(2wks, 4wks and 8wks) changes, A group noticeable changes in cognitive. B group noticeable changes in cognitive and performance(ACL). These results mean cognitive training provides cognitive and performance with Alzheimer's dementia. Comprehensive research is required about a point of time and duration for intervention and severity degree in clinical approach for Alzheimer's dementia.

인삼이 밀가루의 아밀로그래프에 의한 호화 성질과 파리노그래프에 의한 반죽 성질에 미치는 영향을 조사하였다. 인삼첨가 LL면의 조직감과 관능적 특성에 미치는 영향을 분석하기 위하여 밀가루에 대하여 인삼을 5.0∼10% 첨가하여 LL면을 제조한 뒤 면의 조직 특성 분석 및 조리시험을 하고 관능검사를 하였다. 인삼을 첨가하면 아밀로그래프의 호화개시 온도를 3.1℃ 지연시켰으며, 최고 점도를 40B.U 감소시켰다. 파리노그래프의 흡수율은 1.2% 증가하였으며, 반죽의 안정도는 인삼의 첨가로 2.0분 길게 측정되었다. Hunter L값은 인삼 첨가량이 증가할수록 낮아졌으며, Hunter a, b값은 반대로 측정되었다. 인삼첨가 LL면의 층밀림 압출력은 첨가량의 증가에 따라 높아져 10.0%의 첨가는 대조구 18.65(㎏f)보다 2.3(㎏f) 높은 23.95(㎏f)로 측정되었으며, 경도도 대조구보다 5.4(㎏f) 높게 측정되었다. 인삼첨가 LL면의 무게 증가는 인삼의 첨가량이 증가할 때 다소 높게 나타났으나. 부피 증가는 오히려 높게 나타나 조직이 다소 치밀한 것으로 나타났다 용출량은 인삼량의 증가에 따라 약간 감소하였다. 미생물은 인삼의 첨가량이 증가할수록 줄어들어서 장기 저장이 가능하였다. 관능 검사 결과는 인삼첨가 LL면이 4.2 및 4.0으로 비교적 좋은 점수를 얻었다. 이같이 LL면 제조시 인삼 첨가량은 7.0%의 수준이 효과가 컸다. The influence of ginseng on the paste or gelatinization properties by amylograph and mixing properties by farinograph of wheat flour, and on quality properties, color, cooking quality, textural and sensory properties, and reducing microbial population of LL (Long Life) noodles was studied. The contents of ginseng used were from 5% to 10% based on flour weight. The viscosity property of wheat flour with ginseng was increased the initial pasting temperature but the amylograph peak viscosity were decreased in vice versa. The farinograph absorption, stability and breakdown were increased by ginseng. The whiteness of LL noodles manufactured with ginseng was lower than that of control. The shear extrusion force and hardness of LL noodles manufactured with ginseng were shown much higher value than those of control. At cooking quality examination of LL noodles manufactured with ginseng, weight of cooked LL noodles was decreased but volume was appeared in vice versa. Extraction amounts of LL noodles manufactured with ginseng during cooking were much smaller than those of control. Total counts of microorganism of LL noodles manufactured with ginseng were decreased during storage at 30℃. Sensory properties of cooked LL noodles which was manufactured with ginseng showed quite acceptable. Based on the cooking and sensory evaluation test, addition of 7.0% ginseng to wheat flour may be suitable for processing LL noodles.

This study was carried out to evaluate the artificial neural network algorithm for water quality forecasting in Chungju lake, north Chungcheong province. Multi-layer perceptron(MLP) was used to train artificial neural networks. MLP was composed of one input layer, two hidden layers and one output layer. Transfer functions of the hidden layer were sigmoid and linear function. The number of node in the hidden layer was decided by trial and error method. It showed that appropriate node number in the hidden layer is 10 for pH training, 15 for DO and BOD, respectively. Reliability index was used to verify for the forecasting power. Considering some outlying data, artificial neural network fitted well between actual water quality data and computed data by artificial neural networks.

Compound Poisson 수요를 갖는 CONWIP 시스템의 근사적 분석

이정은,이효성 한국경영과학회 1998 韓國經營科學會誌 Vol.23 No.3

In this study we consider a CONWIP system in which the processing times at each station follow an exponential distribution and the demands for the finished products arrive according to a compound Poisson process. The demands that are not satisfied instantaneously are assumed to be backordered. For this system we develop an approximation method to obtain the performance measures such as steady state probabilities of the number of parts at each station, the proportion of backordered demand. For the analysis of the proposed CONWIP system, we model the CONWIP system as a closed queueing network with a synchronization station and analyze the closed queueing network using a product form approximation method. A matrix geometric method is used to solve the subnetwork in the application of the product-form approximation method. To test the accuracy of the approximation method, the results obtained from the approximation method were compared with those obtained by simulation. Comparisons with simulation have shown that the approximate method provides fairly good results.
