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.

Objective : Our purpose was to make preparations of what for proper emergency care and delivery in order to improve maternal and fetal well-being. Methods : The study was undertaken for the clinical evaluation and statistical analysis on the patients with placenta previa who had been admitted and delivered at Soonchunhyang University Hospital from January, 1994 to May, 1998, retrospectively. Results : The incidence of placenta previa was 2.0%. Placenta previa has occurred more often in multigravida(92%) than primigravida(8%). Vaginal bleeding was most frequent(37.3%) presentation. The mean gestational age at the first bleeding episode was 31~35 weeks(46.4%). The type of placenta previa was totalis (31.3%), Partialis(18%), marginalis(32.7%), low lying(18%). Conclusion .

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).

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.

For the efficient determination of activity against solid tumors, an in vitro tumor model that resembles the condition of in vivo solid tumors, is required. The purpose of this study was to establish a rapid culture method and viability assay for an in vitro 3-dimensional tumor model, multicellular spheroid (MCS). Among 12 human cancer cell lines, a few cell lines including DUD-1 (human colorectal carcinoma cells) formed fully compact MCS which was adequate for in vitro viability assay. DLD-1 MCS showed steady growth reaching 700 pm diameter after 11 day culture. DUD-1 cells grown as MCS showed significant increase in G_(0)/G₁ phase compared to the monolayer cells (73.9% vs 45.7%). but necrotic regions or apoptotic cells were not observed. The cells cultured as MCS showed resistance to 5-FU (10.3 fold higher IC_(50)) compared to monolayers. however, tirapazamine (a hypotoxin) showed similar activity in both culture systems. In summary, MCS may be a valid in vitro model for activity screening of anticancer agents against human solid tumors and also exploitable for studying molecular markers of drug resistance in human solid tumors.

Cerebrovascular disease is a major cause of cognitive and physical impairment in hemiplegic patient. hemiplegic patient survivors often face a long physical therapy process to regain a normal life. physical therapist must assess the probable outcome of their patients physical therapy program, and their ability to accurately estimate a patient level. A "pusher syndrome" encompassing postural imbalance and hemi-neglect is believed to aggravate the unaffected side of the body. Standard treatment for pusher syndrome in hemiplegic patient includes definition, character, typical sign and treatment.

Many studies revealed the neuroprotective, cardioprotective, and chemopreventive actions of dietary flavonoids. The plausible mechanistic interpretation of the various effects of flavonoids was concentrated on the anti-oxidant or free radical-scavenging properties of these phytochernicals, both in model systems and under in vivo conditions. While there has been a major focus on the anti-oxidant properties. there is an emerging view that flavonoids and their in vivo metabolites. do not act as conventional hydrogen-donating anti-oxidants. but they may exert regulatory functions in cells through actions at protein kinase or lipid kinase signaling pathways. Flavonoids and more recently their metabolites. have been reported to act at phosphoinositide 3-kinase(PI 3-kinase). Akt/protein kinase B(Akt/PKB), protein kinase C (PKC), mitogen activated protein kinase(MAP kinase), and various tyrosine kinases signaling cascades. Inhibitory or stimulatory actions at these pathways are likely to affect cellular function profoundly by altering the phosphorylation state of target molecules and by modulating gene expression. A clear understanding of the mechanisms of action of flavonoids, either as anti-oxidants or modulators of cellular signaling pathways, and the influence of their metabolism on these properties are key to the evaluation of these potent biomolecules as anti-cancer agents, cardio-protectants, and inhibitors of neurodegeneration.

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.
