In this paper, an algorithm for fault location in Auto Transformer (AT) Feeding Railway system is presented. If a fault occurs at the AT feeding circuits of electrical railway system, it is very important to find fault location and to remove it immediately for the purpose of ensuring safety for transportation. Because the characteristics of reactance - distance are not linear, only using one terminal signals to give fault distance is difficult. In this paper, first, using the KVL, 4 voltage equation are obtained. Secondly, eliminatillg voltage a distance equation which consists of currents at rail and line parameters including mutual effects.

서정아,김재곤,백병주,양연미,이용희,김상훈 大韓小兒齒科學會 2004 大韓小兒齒科學會誌 Vol.31 No.4

본 연구의 목적은 chlorhexidine(Cervitec)과 fluoride(Fluor-protector) 성분을 각각 포함한 varnish를 치아에 적용하였을 때 타액내의 mutans streptococci의 수의 감소에 미치는 효과를 알아보기 위한 것이다. 전북대학교 치과대학생 40명을 대상으로 하여 mutans streptococci 균종 수를 평가하였으며, 이들을 무작위로 네 군으로 나누어 다음과 같이 varnish를 적용하였다; A) varnish를 적용하지 않은 군(n=10), B) chlorhexidine varnish 적용군(n=10), C) fluoride varnish 적용군(n=10), D) chlorhexidine과 fluoride varnish를 모두 적용한 군(n=10), Mutans streptococci 수 측정에는 Orion diagnostica 사의 Dentocult SM을 사용하였다. Varnish를 적용하지 않은 상태에서 1차로 Mutans streptococci 수를 측정한 후 각각의 varnish를 적용하였으며, varnish 적용 12주 후 다시 측정하여 기록하였다. 모든 실험군(group B, C, D)에서 12주 후에 측정한 Mutans streptococci 수가 감소한 개체가 증가한 개체보다 많았으나 통계적으로 유의한 차이는 보이지 않았다(p>0.05). 실험에 사용된 어떠한 varnish도 적용 12주 후에 타액 내 mutans streptococci 수에 통계적으로 유의할 만한 변화를 주지는 못하는 것으로 나타났다(p>0.05). The objective of the present prospective trial was to compare the efficacy of chlorhexidine(Cervitec), Fluoride(Fluorprotector) and combination of chlorhexdine and fluoride varnishes in decreasing the level of salivary mutans streptococci. Forty healthy students of school of dentistry, Chonbuk national university were investigated to evaluate mutans streptococci(MS) counts and randomized into four groups to treat with the experimental varnishes: A) untreated group(n=10), B) chlorhexidine group(n=10), C) fluoride group(n=10), D) chlorhexidine and fluoride group(n=10). Dentocult SM^(�)(Orion Diagnostica) strip method was used for measurement of the level of mutans streptococci in saliva. Stimulated saliva were collected at baseline for mutans streptococci counts evaluation(ms1), 12 weeks later the completion of each varnish treatment, mutans streptococci counts were re-evaluated. In varnish group with chlorhexidine, fluoride and combination of chlorhexidine and fluoride, the level of mutans streptococci was lower after 12 weeks than at baseline, but there were no significant differences in saliva(p>0.05), when compared with baseline. After 12 weeks, a remarkable reduction was still found in the subjects with high level of mutans streptococci at baseline, but not different in the low and moderate level of mutans streptococci(p>0.05).

서욱장,정선미,고수진,이창근,김재승,임주혁,유빈,문희범 대한핵의학회 2003 핵의학 분자영상 Vol.37 No.5

Purpose: We describe a 54-year-old woman with systemic lupus erythematosus (SLE) who suddenly presented with chorea and had positive antiphospholipid antibodies. F-18 FDG PET showed abnormally increased glucose metabolism in bilateral putamen and primary motor cotex. Tc-99m ECD SPECt also showed abnormally increased regional cerebral blood flow in bilateral putamen. She was treated with corticosteroid and aspirin after which the symptoms improved. Four months later, follow up F-18 FDG PET showed improvement with resolution of hypermetabolism in bilateral putamen. This case suggests that striatal hypermetabolism is associated with chorea in SLE.

신재필,이상희,서형덕,김인택 경북대학교 병원 1998 경북대학교병원의학연구소논문집 Vol.2 No.1

동물실험에서 aconite 또는 aconitine은 신경계통에 독성을 나타낸다고 이미 알려져 있다. 그러한 독성은 시유발전위와 병리조직에서 탈수초증으로 나타난다. 저자들은 실험적으로 aconite을 주입하여 탈수초신경증을 일으킨 후 고용량이 methylprednisolone(MP)투여가 효능이 있는지를 알아보고자 하였다. Aconite를 복강내 주입하고 곧 이어 가토의 이연정맥으로 MP를 주입한 군과 aconite만을 주입한 군으로 나누었고 이들을 서로 비교하였다. 그리고 이 두 군을 정상군과도 비교하였다. 시유발전위에서 aconite를 주입후 MP를 투여한 군에서 aconite만을 주입한 군에 비하여 onset latency와 peak latency 그리고 진폭 모두에서 2주째에 통계학적으로 의미있게 회복되었으나 (p<0.05) 정상군과 비교하여 의미있는 차이를 나타내지 아니하였다. 그러나 정상군과 비교하여 1개월과 2개월에서 onset latency은 의미있게 지연되었고 (p<0.05) peak latency와 진폭은 다소 회복되었으나 정상군의 평균값에는 미치지 못하였다. 병리조직에서 MP으로 치료한 군과 aconite만을 주입한 군 모두에서 수초의 탈수초변화가 관찰되었으나 MP으로 치료한 군은 상대적으로 탈수초변화가 현저하지 아니하였다. 본 연구에서 실험적으로 가토에 aconite를 전신에 투여하여 시신경병증을 일으킨 후 고용량의 MP를 즉시 투여한 경우에 시신경의 기능을 정상상태까지 회복시키는데는 한계가 있으나 부분적으로 시신경의 기능을 회복시키는데 도움이 될 것으로 생각된다(한안지 37:1730~1740, 1996). Studies in animals indicate that aconitine or aconite has toxic effects in the visual system of a rabbit model. Such a toxic effects causes myelo-optic neuropathy in the visually evoked cortical potential(VECP) and histopathologic studies. Whether the administration of intravenous high-does of methyprednisolone(MP) in the myelo-optic neuropathy caused by aconitine(1.5㎖/㎏, equivalent to 0.7㎎/㎏ of aconitine) is experimentally effective remains uncertain. The group treated with MP(daily 30㎎/㎏×2 for 3 days followed by 15㎎/㎏ for 3 days) in addition to aconite was compared with the aconite alone group and the normal control group. In the MP treated group, increased recovery of onset latency, peak latency, and amplitude in VECP in comparision with the aconite alone group was recorded at 2 weeks(p<0.05). The MP treated group in comparision with the normal control group showed a significant delay in onset latency at 1 month and 2 months(p<0.05). But, the amplitude in both the MP treated group and the aconite alone group increased at 2 months and did not show a significant difference in comparision with the normal group(p<0.05). In histopathologic study, pathologic findings of myelin sheath in the MP treated group were less severe than in the aconite alone group generally. The true benefit of high-does MP was at least clear within 2 weeks. The authors conclude that treatment with intravenous high-does MP immediate after aconite injection may have some beneficial effects in recovery of neurologic function although such a treatment do no have the definite recovery in aconite induced myelo-optic neuropathy(J Korean Ophthalmol Soc 37:1730~1740, 1996).

The purpose of present study was to evaluate the bioequivalence of two enalapril maleate tablets, Renitec^(™) (MSD Korea Ltd.) and Enalace ^(™) (Welfide Korea Ltd.), according to the guidelines of Korea Food Drug Administration (KFDA). Twenty-four normal male volunteers, 22.33±2.55 year in age and 66.54±8.30 ㎏ in body weight, were divided into two groups and a randomized 2×2 cross-over study was employed. After two tablets containint 10 ㎎ of enal-april maleate per tablet wre orally administered, blood was taken at predetermined time intervals and concentrations of enalapril in plasma were determined using LC-MS-MS. Pharmacokinetic parameters such as AUC_(t), C_(max) and T_(max) were calculated and ANOVA test was utilized for the statistical analysis of the parameters using logarithmically transformed AUC_(t) and C_(max) untransformed T_(max). There were no sequence effects between two formulations in these parameters. The 90% confidence intervals for the log transfored data were acceptance range of log0.8 to log1.25(e.g., log1.02∼log1.14 and log1.03∼log1.19 for AUC_(t) and C_(max), respectively). The major parameters, AUC_(t) and C_(max), met the criteria of KDFA for bioequivalence indicating that Enalace^(™) tablet is bioequivalent to Renitec^(™) tablet.
