A 63 year-old woman who had diagnosis of multiple sclerosis complaining left hemiparesis and fluctuating decreased visual acuity in her right eye and abnormal findings in pattern shift visual evoked potentials(PSVEPs) and on T2 weighted MR scanning. We treated her subcutaneously with 250μg interferon (3-lb(ITFß -lb) every other day. There were detected pancytopenia, skin rash, and abnormal liver function test seven days after the therapy. In spite of reducing the dose of interferon injection, abnormal laboratory findings were not returned to normal. Dose adjustment of interferon-I3 for body weight or race, may be helpful to reduce the side effects.

It has been recently reported the possibility in the transfer of antimicrobial resistant to other animals and humans. In particular, the occurrence of vancomycin resistant enterococci (VRE), which have been known as a principal antimicrobial resistant bacteria in humans, has been increased as a pathogen of nosocomial infections. And then animal VRE were suspected as an origin of human VRE. In this work, we investigated the relatedness between VRE from animals and humans through random amplified polymorphic DNA (RAPD) typing. The genetic relatedness of vanA, vanB, vanC-1 and vanC-2 genotypes was examined by RAPD typing, respectively. van4 genotypes have not been shown high genetic relationship each other, containing VRE from humans (n = 8) and chickens (n = 5). In vanB genotypes from humans (n = 3), 2 isolates were made up one cluster, shown 77.8% homology. Chicken isolates of vanC-1 genotypes (n = 11) were constituted 2 clusters and the homology of 2 clusters was 81.8% and 80.0%, respectively. In case of vanC-2 genotypes (n = 19), 2 isolates from pigs have been shown 76.9% homology. But, between VRE from animals and humans, the isolates of high genetic relationship could not be found and RAPD typing was a useful epidemiological method that could be confirmed the genetic relationship among VRE.

The technique of electronic working length determination has gained considerable popularity among both endodontists and general dentist. Recently, the Root ZX(J.Morita Corp., Tokyo, Japan) has been developed with unique electronic features that are claimed to maintain the instrument's accuracy regardless of canal condition. The purpose of this study is to compare the accuracy of the Root ZX with estimates of actual canal length, in vitro model and in vivo under the various condition. 1. The experiment in vitro model 50 extracted, single-rooted and single-canaled, teeth with mature apices were selected. The extirpated teeth were placed in a saline-soaked Oasis, and measured with Root ZX according to manufacturer's instruction in the dried canal and saline-irrigated canal. The teeth were then removed from the model and the actual canal length was measured. The values of canal length in each conditions were used for evaluating the results. 2. In vivo study 15 teeth which destined for extraction were selected. Once access was gained, the canals were irrigated using 5.25% sodium hypochlorite and were not dried prior to insertion of the measurement file. Once the Root ZX indicated the C-D junction, self-curing resin was injected into the canal. The tooth was extracted and ground with a bur and Soflex disk. This was done until the terminus of the file and the root was revealed. The distance from the end of the file to the foramen(major diameter) was measure, and evaluated. The results were as follows: 1. In vitro study(A/B : difference between A and B) 1). The mean values of acutal length/dried canal length and actual length/saline irrigated canal length were 0.528㎜, and 0.525㎜ respectively. There is no significant difference between the means of acutal length/dried canal length and actual length/saline irrigated canal length. 2). Root ZX could locate the C-D junction at the point of 0.5㎜ inside of major foramen, in both dried canal and saline-irrigated canal. 2. In vivo study 1). Root ZX could locate the the C-D junction at the point of 0.5㎜ coronal to the major foramen in presence of 5.25% NaOCl. 2). Root Zx located a point that was perceived to be the apical constriction. The majority of file tip experimented were within the canal, not extended beyond the major foramen.

The matrix of ductile cast iron are welded by pre-heating it at 300℃ in the room temperature. Through the mechanical, non-desbructive testing and analysis of the composition. the possibility if arc welding of ductile cast iron are studied as follows; 1. L electrode is the best among them in weldability, impact value and machinability. The next is LB electrode followed by S electrode. C electrode is last. However, the tensile strength showed in the following order: LB, S, L, C. 2. LB, S, L, C, all are available for the welding of cast iron. 3. The above experiment showed that L and LB are good in general. In addition LB is low in price, we therefore prospect that it will be widely used as the electrode for cast iron.

Objectives : This study aims to estimate the prevalence of the DSM-IV psychiatric disorders in Korean population using the Korean version of Composite International Diagnostic Interview (K-CIDI). Methods : Subjects were selected by taking multi-stage, cluster samples of 7,867 adult household residents, 18 to 64 years of age, in ten catchment areas. Total 78 trained interviewers administered the K-CIDI to the selected respondents, from June 1 to November30,2001. Results : Total 6,275 respondents completed the interview. Some 33.5% of respondents reported at least one lifetime disorder, 20.6% reported at least one-year disorder, and 16.7% reported at least one-month disorder. The most common lifetime disorders were alcohol abuse/dependence (17.24%), nicotine dependence/withdrawal (11.19%), specific phobia (5.16%), and major de-pressive disorder (4.25%). The lifetime prevalence of substance abuse/dependence (0.25%) and schizophrenia (0.16%) was very low. Nicotine and alcohol use disorder showed very high male/female ratio. Mood disorder and anxiety disorder were more prevalent among female than male. Conclusion : The prevalence of psychiatric disorders was high. In comparison with other studies, remarkable differences in distributions of psychiatric disorders across the areas and times were observed.

Chaotic behavior of bubbles has been investigated in a pressurized bubble column(0.1-0.6MPa). The bubble properties have been measured by means of resistivity probe method and the pressure fluctuations by the semi-conductor type pressure transducer. The number density distributions of the individual bubble chord length have been represented by the logarithmic normal distributions, by which the mean chord length of a bubble has been determined. The pressure fluctuations due to the bubbling phenomena in the column have been analyzed by resorting to the deterministic chaos theory; the mutual information function, phase space portraits and correlation dimension have been obtained from the time series of pressure fluctuations. It has been found that the mutual information function, phase space portraits and correlation dimension can be utilized to describe and explain the non-linear dynamical behaviors as well as the bubble properties in pressurized bubble columns, since they can provide quantitative measures of dynamical behaviors, arising from the complex gas-liquid flow.
