Demand of rapid detection for cancer, it is necessary that high sensitivity, specificity, low cost, and simple method. CNT and metal nano materials are widely used to elecate efficient. CNT have various advantage, and can be composed with metal nano materials. Especially, Titanium oxide and gold nano particles are focused on sensor for detection of cancer, it can elecate electron transition feeiciency between electrode surface and target materials, and biological functionalization of CNT. It means that nano material is composed each other. In this study, electrodes are considered materialsd and their chracteristic for cancer sensor.

Newly developed albendazole (Zentel®) is a broad spectrum anthelmintic with high activity against intestinal nematodes as well as trematodes and cestodes infections. The present study was undertaken to observe the morphological changes of Hymenolepis nana which obtained from experimentally infected mice after treatment with albendazole. For this study 20 mice were artificially infected with eggs and 16 of them were given albendazole (1×100mg/kg) four weeks after infection. The worms were collected from the small intestine of the mice which were autopsied at 1 and 2 hours after treatment. The fine structure of the collected worms were studied by means of scanning and transmission electron microscopies. The findings were compared with those of untreated worms. The results are as follows: 1. The worms obtained from non-treated mice showed that the whole surface is covered with many microtriches. Microtriches of H. nana may be divided into three anatomical regions; a base, junctional region and cap. Tegumental layer showed well developed syncytium which included a lot of number of discoidal secretory bodies. 2. Many blebs were formed on the surface of the damaged tegument of the worm at 1 hour after treatment with albendazole. The bleb was packed by plasma membrance and included matrix which uniform electron density. Some bleb surface has microtriches. 3. The destruction of tegumental syncytium was recognized at 2 hours after treatment with albendazole. Therefore the blebs on the worm sufrace caused to the death by the tegumatal bursing.

한왕수,한상진,김정목,조양자 대한감염학회 1989 감염 Vol.21 No.1

Compylobacter pylori may cause gastritis and has been proposed as an etiologic factor in the development of peptic ulcer. However, it is unknown where is primary colonization sites of C. pylori. Isolation sites of C. pylori in stomach and duodenum and pathology in antrum were evaluated in 90 subjects endoscoped at Hanyang University Hospital in Seoul, Korea. C. pylori detected in biopsied specimens of 40 (74%) of 54 C. pylori-positive patients at antrum only, and 13 (24%) of the same patients at antrum and body, but did not detected in duodenal biopsied specimens. Antral pathology results were chiefly found in active chronic gastritis. These findings strongly suggest that antrum is a primary colonization sites of C. pylori and the agent may be spread within stomach from the antrum.

The dental high-speed handpiece is one of the most popular and important devices that has been widely used as the main means of cutting tooth structure and restorative materials in dentistry, In consideration of usage and marketability of the dental handpiece, it is obviously worthy of investigating it. In this paper, a high speed dendal handpiece is developed through reverse engineering with 3D X-Ray CT equipment and wire cutter for the Mark II model in NSK. The demension of the handpiece parts is obtained through this process, and 3D modeling is performed with CATIA V5. The interference between parts can be examined through the part assembly in CATIA, and the performance is finally compared with Mark II model in NSK.

An effort to connect political education in terms of theory to educational practice is important because practical strategy through designing curriculum, and instructional planning is a crucial for political devlopment and political changes. This study explores tasks and problems of political education, current issues in debate in relation to the establishment of political education in schools, and the possibilities and limitations of political education in Korea. Besides, this study examines the possibilities and limitations of civic education and of unification education in the relation to the political education. The major conclusion is that in order to achieve more efficient political education we need an exact diagnosis of political ideology and value system of the students across all the educational system and an overall efforts to highten political consciousness through educational practice.

발파진동의 크기에 미치는 디커플링효과의 연구

김왕수,임한욱 강원대학교 산업기술연구소 2000 産業技術硏究 Vol.20 No.A

The pressure-time profile of the explosion gases can controlled for the use of cartridge explosive with two techniques known as Decoupling and spacing of the charges. Decoupling consists of a space between the explosive column and wall of the blast hole. Four different decoupling index 1.4, 1.8, 2.34, 3.0 are selected in this field study. The level of ground vibrations with each decoupling index was measured and the empirical particle velocity equation from these data was obtained. The condition of new cracks at blast hole are also examined. As the decoupling index is increased, the level of the blast vibration is decreased. But the cracks in rock masses are efficiently formed to remove the broken rock. The vibration constant associated with test sites is given as K=1564.5(D.I)^-1.3233 in terms of D.I.(decoupling index)

Since the advent of computed tomography(CT). there have been growing evidences of cerebral structural abnormalities in schizophrenics. Among them. reversed hemispheric asymmetry has been regarded as impaired cerebral lateralization of schizophrenics representing another pathology different from brain atrophy. To investigate the pattern and frequency of reversed cerebral asymmetry and their relationship with brain atrophy. we analyzed widths of frontal and occipital region on the brain CT scans of right-handed 56 schizophrenics and 52 normal controls by a manual method. Brain atrophies were assessed using fixed arm planimetry and visual lineat measurements. Compared to normal controls. the schizophrenics show significantly increased frequency of reversed occipital asymmetry. Dividing the schizophrenics into group according to the evidences of atrophy revealed more reversed occipital asymmetry than those with brain atrophy. These findings suggest that reversed cerebral asymmetry might be unrelated to brain process and would be a neuroanatomic evidence of abnormal asymmetry of schizophrenices.

Two hundred and fourty eight strains of Pseudomonas aeruginosa isolated from clinical materials at Department of Bacteriology in National Medical Center and Han-iI Hospital during January to November in 1973, were typed serologically by Hommos agglutination method utlizing a routine set of 13 standard sera. In addition, their susceptiblity to several kinds of antibiotics were determind. The following results were obtained; One hundred seventy eight strains (71,77%) were typable with an occurrence of type T5 in 41 strains (16. 58%), type T5, in 36 (14.52%), type T3, in 24 strains (9. 68%) and smalI numbers of strains were distributed in other types. Seventy strains (28. 23%) were nontypable. The rate of isolation of Pseudomonas by clinical meterials was shown as 49. 19% in ous, 16. 53% in sputum and 8. 87% in urine; the isolation rate of 1. 21-3. 15% was shown in other clinical meteraIs and the definite distribution rate could not be observed in the serotype by different materials. Majorities of strains used in this experiment of isolates were resistant to common antibiotics but Gentamycin and Carbenicillin, known relativeIy as sensitive antibiotics to Pseudomonas aeruginosa, were observed resistance of 2. 44-10. 5% and 16. 69-57. 8%. Moreover any particular relationship between serotype and the sensitivity of antibiotics was not identified.

Twenty-five ㎎ of ephedrine of its matching placebo was administered to 200 male collegians for the study of the effects of ephedrine on motor fitness(10m shuttle-run, chinning, running broad jump and target throwing). Ephedrine improved motor fitness by 1% to 5% in the low group, but statistical analysis showed no significance in the high group. And in the case of target throwing the effect of placebo was a little more than ephedrine both in the low group and in the high group.
