      • 안정된 광 솔리톤 전송영역에 대한 연구

        최봉수,이명우,서동선,김석진 明知大學校 産業技術硏究所 1995 産業技術硏究所論文集 Vol.14 No.-

        We numerically investigate stable propagation regimes of 10 ㎓ train of optical solitons with 17.6 ps widths to determine the acceptable variations of periodic amplifier gain(△G), dispersion(△D), and initial chirp(C), as a function of the amplification period LP. We fine that, when LP = 25 km, the acceptable variations are △G = ±4%, △D= ±12%, and C= -0.36 ∼ 0.39. The variations decrease as the amplification period LP increases.

        PCR을 이용한 국내 및 수입 축산물 유래 Listeria monocytogenes의 유전학적 분석연구

        우용구,이수화,이철현,최정수,류재두,김영일,이오수,김봉환 한국수의공중보건학회 2003 예방수의학회지 Vol.27 No.2

        One hundred-fifty two of Listeria strains were isolated from domestic chicken carcasses, a slaughter-houses from nationwide from 1996 to 1997 and imported livestock products from a ten foreign countries including the USA, China, France and Thailand. To substitute the laborious and time consuming procedures of clinical laboratory standard diagnostic methods, the rapid and specific multiplex PCR(M-PCR), which was designed to amplify a three kinds of genes simultaneously f3r specific detection and differentiation of L. monocytogenes(LM) by one step procedure, was established. The LM strains confirmed with M-PCR were analysed to their genetic diversities by RAPD using the two primers(D87 & MMTl), and also evaluated on their discriminatory abilities(na) between two primers. our study also conducted the REP-PCR and ERIC-PCR for evaluation of the possibility of REP and ERIC elements for genetic subtyping of LM strains. According to the REP-PCR and ERIC-PCR fingerprinting patterns, LM strains were divided into 7(ERIC-type) and 4(REP-type) major clusters at the relative clone cut off value of 80%. According to the computer analysis of PCR results using the GelCompar Ⅱ software, ERIC-PCR(DI=0.955) had expressed the most high discriminatory ability and followed by REP-PCR(DI=0.952), RAPD(D87; 0.954, MMT1; 0.937), in order. The combined analysis of the present PCR results was also expressed the reliable and useful discriminatory ability(DI=0.916). This study suggested that PCR based methods could be used as an reliable, reproducible, rapid, and highly discriminatory method for the genetic differentiation of genus Listeria.

      • 담즙정체성 간염의 임상적 양상

        최선택,은종렬,임상우,김봉준,이헌주,구미진,최준혁 영남대학교 기초/임상의학연구소 2001 Yeungnam University Journal of Medicine Vol.18 No.1

        Background: Cholestatic hepatitis is failure of bile to reach the duodenum with hepatocellular damage and no demonstrable obstruction of the major bile ducts. The prognosis is usually good with recovery in less than 4 weeks after withdrawal of the offending drug. However, a prolonged course lasting over 3 months is possible and, in rare cases, progression to ductopenia with development of a vanishing bile duct syndrome occurs. A differential diagnosis with other causes of Chronic liver disease is needed. Materials and Methods: From January 1991 through Jaunary 2000, 14 patients diagnosed as cholestatic hepatitis by liver biopsy were inclouded. The possible causative drug, clinical features, laboatory findings, and progression of cholestatic hepatitis were evaluated. The semiquantitative study of liver lesions was performed by two independent observers. Results: Causes of cholestatic hepatitis are 5 cases of oriental medicine, 3 cases of anti-tuberculosis medication, 1 case of ticlopidine and antibiotics and 4 cases of unknown causes. The clinical features of cholestatic hepatitis were jaundice, itching, urine color change, and general weakness. During 6 to 30 months, LFT of 5 patients showed prolonged elevation. Elevated total cholesterol ≥250 mg/dL in 6 patients, pheripheral blood eosinophilia in 5 patients, auto-antibody positive in 6 patients were observed respectively. The biopsies showed intralobular bilirubinostasis with a mixed portal inflammatory infiltration. Conclusion: In cholestatic hepatitis. durations of abnormal LFT are variable regardless of causative drugs. If cholestatic hepatitis progresses toward chronic course, viral hepatitis, primary biliary cirrhosis, and autoimmune hepatitis should be differentially diagnosed and sequential liver biopsies are needed.

So that can grasp whole structure of video, do sampling in still image, Made user can grasp whole structure of video, do sampling in still image. Made user grasp scene change point of total video on one eye. If MSE of each frame exceeds critical value, search the frame by scene change.

      • 적외선 센서를 이용한 다종가스 계측기 구현

        최낙진,류정호,강봉휘,이광우,이덕동 경북대학교 센서기술연구소 1997 센서技術學術大會論文集 Vol.8 No.1

        The semiconductor gas sensors with a tin oxide as the raw material have been generally used to detect gases in the principle of electrical conductivity variation. However, it was difficult to design the gas detection system due to the non-selectivity, the non-stability and the influence of temperature, humidity etc. Therefore, it was proposed NDIR(non-dispersive infrared) method using pyroelectric infrared sensor to overcome the disadvantage of the semiconductor gas sensors. This method has been recently used to detect various gases in industrial parts. It has the advantages of selectivity, stability and responsibility. The gases used in this paper were CO_(2)(carbon dioxide) and HC(hydrocarbon) series. The system was designed with the Intel MCU i8097BH microprocessor. Main topics were to remove interference effect for other gases and to minimize influence for ambient circumstance by using the software and the hardware techniques.

        최영식,이상용,김유훈,조갑래,이봉우,양경무,정낙은,서중석,이한영,이원태,강현욱 大韓法醫學會 2000 대한법의학회지 Vol.24 No.2

        Disposal of a homicide victim by dismemberment is rare, but individual cases are on record in most major medicolegal departments. Recognition of postmortem mutilation may be of importance in the interpretation of certain murders committed by sexual perverts and other mentally deranged individuals and sometimes performed for the sole reason of easier disposal of the body. Postmortem dismemberment is usually readily recognizable as such; The edges of the injuries are dry and lack evidence of bleeding. The joints may be disarticulated without fracture, or the use of an axe or saw may be evident from examination of bones. Parallel horizontal or oblique furrows in the bone surface are caused by skipping of the saw prior to establishing depth. Such patterns on the bone may assist in identifying the particular saw involved. So we report 25 dismembered corpses that autopsied in National Institute of Scientific Investigation. This paper can help in attempting to establish not only the first criminal investigation steps but also the medicolegal approach methods in unidentified and dismembered deaths.

        Small Dam의 斜面安定 解析

        최기봉,배우석,안병철 한국안전학회 2004 한국안전학회지 Vol.19 No.2

        The paper describes a procedure for the evaluation of the effect of seepage force on stability of slopes. The stability of an embankment impounding a water reservoir is highly depend upon the location of seepage line with the embankment. To evaluate the accurate safety factor of an embankment, it is important to illustrate the seepage phenomenon. Of particular interest is the stability following a rapid change of reservoir level. Seepage forces in embankments are easily determined if frictional forces are expressed in relation to hydraulic gradient I. If a piezometer is inserted into a body of embankment, the level to which free water rises is a measure of the energy at that point.

      • 호기성 미생물을 이용한 크롬의 생물학적 환원

        최성우,이봉섭,곽명화,윤철종,박승조 동아대학교 환경문제연구소 2001 硏究報告 Vol.24 No.2

        Chromium occurs naturally in the earth's crust as well as in air, surface, and ground water. However, chromium is released to the environment in much larger amounts as a result of human activities. Hexavalent chromium, Cr(Ⅵ), is very soluble in water in natural environment and very toxic, carcinogenic, and mutagenic in animal and man. On the other hand trivalent chromium, Cr(Ⅲ), is less toxic and less soluble and thus is a lesser problem. This study has been carried out in order to reduce toxicity of Cr(Ⅵ) by an Escherichia coli strain. After adding E. Coli., the results were obtained from concentration of total Cr, Cr(Ⅵ). Cr(Ⅲ), pH, turbidity, and VSS in aerobic condition was summarized as follows : After 48hr aerobic condition in experiment of synthetic wastewater, the reduction rate of Cr(Ⅵ) was 20%. Also, the reduction rate of Cr(Ⅵ) was 60% in experiment of raw wastewater.
