This study was conducted to investigate the pain relief score and the degree of satisfaction among elderly people. This study has done from July 11th, 2001 to August 31st, 2001 at Hydrotherapy Facility in the College of Bogun(Taejon Health Sciences College) located in Taejeon, Korea. Eighty-eight patients were participated to the questionnaire. The results were as follow. 1. The mean value of the pain relief score in the female group was higher than the mean value of the pain relief score in the male group(p<0.05). The mean value of the pain relief score in the group having religion was higher than the group not having religion(p<0.05). The pain relief score was not significantly different in age, presence of spouse, the way of housing, and academic background. The degree of satisfaction was not significantly different in sex, age, presence of spouse, the way of housing, religion, and academic background. 2. The pain relief score and the degree of satisfaction were not significantly different in the presence of comorbidity, going with the hydrotherapy, and the moment of diagnosis. 3. According to the ADL, the mean value of the pain relief score in the Independent was higher than the mean value in maximal assistance and minimal assistance(p<0.05). Independent, maximal assistance and minimal assistance were not significantly different in the degree of satisfaction (p<0.05). 4. The pain relief score and the degree of satisfaction were not significantly different in the legion of pain.

The present study was conducted to investigate the effects of Korean red ginseng water extract (KRGWE) on developmental toxicity caused by the environmental estrogen bisphenol A (BPA) in Sprague-Dawley rats. fifty males successfully mated were randomly assigned to five experimental groups, 1.e., group I (vehicle control), group II (BPA 1000mg/kg), group III (KRGWE 400mg/kg), group IV (BPA 1000mg/kg & KRGWE 200mg/kg), and group V (BPA 1000mg/kg & KRGWE 400mg/kg). The test articles were administered by gavage to mated females from gestational days (GD) 1 through 20 (sperm vaginal lavage=day O). All females were subjected to caesarean section on GD 21 and their fetuses were examined for external, visceral, and skeletal abnormalities. In the group II, significant maternal toxic effects including suppressed body weight, decreased body weight gain during pregnancy, and reduced food consumption were observed in pregnant rats. The minimal developmental toxicity including fetal ossification delay was also found in fetuses. In addition, a tendency for increased pregnancy failure, increased pre-and postimplantation loss, and decreased fetal body weight was observed. However, no fetal morpho-logical abnormalities were seen in surviving fetuses at a dose level of 1000mg BPA/kg. On the other hand, the maternal toxicity and developmental toxicity found in the groups IV and V were comparable to those of the group II. There were no adverse signs of either maternal toxicity or developmental toxicity in the group III. These results showed that administration of BPA at a dose level of 1000mg/kg to pregnant rats resulted in significant maternal toxicity and minimal developmental toxicity, and that no protective effects on BPA-induced maternal toxicity and developmental toxicity were found by concomitant gavage dosing of KRGWE.

In order to develop a antimicrobial agent, dried Sophora flavescens Ait. was extracted with several solvents, and than antimicrobial activity was investigated. The minimal inhibitory concentration (MIC) of the extracted substance against microorganisms were also examined. Antimicrobial activity of the initial methanol extract from the sample was the strongest compared to those of other solvent extracts such as $H_2O$, n-hexane, chloroform, ethyl acetate and methanol. The methanol extract had strong growth inhibition activity against gram-postive bacteria (MIC, $25~50{\;}{\mu\textrm{g}}/ml$) such as B. subtilis. Among gram-positive bacteria tested, B. subtilis was the most susceptible to the extracted substance. The antimicrobial activity of the methanol extract from the sample had strong growth inhibition activity against gram-negative bacteria such as P. aeruginosa (MIC, $25{\;}{\mu\textrm{g}}$/ml).

An ideal I of a local ring (R, m, k) is said to be m-full if there exists an element $x{\in}m$ such that Im : x = I. An ideal I of a local ring R is said to have the Rees property if ${\mu}$(I) > ${\mu}$(J) for any ideal J containing I. We study properties of m-full ideals and we characterize m-primary m-full ideals in terms of the minimal number of generators of the ideals. In particular, for a m-primary ideal I of a 2-dimensional regular local ring (R, m, k), we will show that the following conditions are equivalent. 1. I is m-full 2. I has the Rees property 3. ${\mu}$(I)=o(I)+1 In this paper, let (R, m, k) be a commutative Noetherian local ring with infinite residue field k = R/m.

In this experiment, we fabricated pyramid-type silicon tunneling devices in which a tunneling current flow between a micro-tip and Si$_3$N$_4$ thin film membrane. A MEMS process was used for the fabrication of the tunneling devices. The micro-tips were formed on Si wafers by undercutting a differently oriented square of SiO$_2$ with KOH. The stiffness of the Si$_3$N$_4$ films were observed and the model for the stiffness calculation, which is useful in predicting the stiffness even when the stiffness ranges beyond the scope of the normal experimental condition, was suggested.

유류오염토양에서 분리한 유류분해균주 중 계면장력 저하능이 우수한 균주를 분리하여 동정한 결과 Pseudomonas aeruginosa D2D2로 판명되었다. 탄소원으로 glucose와 olive oil을 각 1.5%씩 첨가하였을 때 표면장력이 27.9 dyne/cm로 표면장력 저하능력이 가장 우수한 것으로 나타냈다. 생산된 biosurfactant로 ethly acetate 추출하여 crude biosurfactant를 얻었으며, TLC 분석한 결과 glycolipid계열의 biosurfactant임을 확인하였다.

A Bayesian criterion is proposed for a multiple test of two independent multivariate normal populations. For a Bayesian test the fractional Bayes facto.(FBF) of O'Hagan(1995) is used under the assumption of Jeffreys priors, noninformative improper proirs. In this test the FBF without the need of sampling minimal training samples is much simpler to use than the intrinsic Bayes facotr(IBF) of Berger and Pericchi(1996). Finally, a simulation study is performed to show the behaviors of the FBF.

In this paper, we study the optimal design for improved rotation latch system performance. The factors affecting the Torque generated in the armature were chosen as design variables. Utilizing the vertical matrix, the orthogonal array table was created to predict the results through minimal analysis. To confirm the Torque generation amount, by utilizing the commercial electromagnetic analysis software MAXWELL, finite element analysis was performed. The approximation method and experimental design through the commercial PIDO tool PIAnO for optimal design and calculations were utilized to perform experiments using an optimization method with evolutionary algorithms. Using the approximation model, design factors were determined that can maximize the torque generated in the armature, and the simulation was performed.

The authors conducted a study of theoritical background and clinical application of the transitional denture with one subject at The Ohio State University, Graduate School. The applicability of this method is considered to be not so great, however, it is likely to be a advantageous way of approaching to the prospective denture patients with severe periodontal diseases. Especially, in this transitional denture technique, natural teeth are duplicated to reject the development of abnormal oral physiology and some effects occuring during edentulous period. As a result of the minimal surgery and protective measure of denture contouring and tissue conditioning, the transitional denture may show treatment effects to the dentrue surrounding tissues and basal seat tissues.

This paper considers the problems of martingale measures and risk-minimizing hedging strategies in the market with restricted information. By constructing a general restricted information market model, the explicit relation of arbitrage and the minimal martingale measure between two different information markets are discussed. Also a link among all equivalent martingale measures under restricted information market is given. As an example of restricted information markets, this paper constitutes a jump-diffusion process model and presents a risk minimizing problem under different information. Through $It\hat{o}$ formula and projection results in Schweizer[13], the explicit optimal strategy for different market information are given.
