박은하,도연실,양정채,강미라,서현주,정숙인,손준성,기현균,오원섭,백경란,송재훈 대한감염학회 2004 감염과 화학요법 Vol.36 No.6

연쇄알구균에 의한 급성 인후염 후 발생한 반응성 관절염은 급성 류마티스열의 개정된 진단기준을 충족하지 못하면서, 지속적 혹은 재발성의 비이동성 관절염과 발열, 홍반성 결절, 일시적 간기능 이상 등을 보이면서 심장염과 무도증을 드물게 동반하는 질환이다. 따라서, 발열을 동반한 급성 관절염 환자에서 감별해야 할 질환 중의 하나이며, 심근염 예방을 위한 페니실린 요법의 적응증 및 기간에 대해서는 아직 이론이 많은 상황으로, 보다 광범위한 연구가 필요하다. 저자들은 연쇄알구균에 의한 급성 인후염 1주 후에 발생한 하지의 다발성 비이동성 관절염과 함께 결절홍반 및 일시적 간기능 이상을 보인 환자에서 PSRA로 진단하고 비스테로이드성 항염증제 및 스테로이드로 성공적인 치료를 하였기에 이를 문헌 고찰과 함께 보고하는 바이다. Poststreptococcal reactive arthritis (PSRA) is associated with recent streptococcal infections. However, PSRA is distinct from acute rheumatic fever by its clinical manifestations: non-migrating arthritis, erythema nodosum or erythema multiforme, and transient elevation of serum transaminases. We experienced a 33-year-old man who presented with fever, arthritis of both knees and ankles, and erythema nodosums on extensor surfaces of lower legs which developed 6 days after the onset of pharyngitis symptoms. Blood and urine cultures were negative. Throat culture was negative for group A β-hemolytic streptococcus. The ASO titers increased up to 2080 IU/mL in sequential monitoring. The result of bone scan was compatible to arthritis of both knees and ankles. There were no signs or symptom of carditis. He showed clinical improvement with anti-inflammatory drugs (naproxen 1,000 mg/day and prednisolone 7.5 mg/d). PSRA should be included in the differential diagnosis of patients presenting with arthritis combined with fever.

양승복,이재도 대구보건대학 1994 대구보건대학 論文集 Vol.14 No.-

Many small systems, utilizing microprocessors, are now being used in various fields. The need for connecting small system is increasing, which locate within a restricted area such as a single bulding, a small cluster of buldings. Utilizing inexpensive microprocessors, we have studied a structure of the multi-loops network system, intra-loop transmission and inter-loop communication schemes. The multi-loop structure, which consists of a number of loops, has been adopted, therefore some loops can be easily added when the number of nodes increases or the traffic rate becomes higher. Each loop is controlled independently, so that trouble of one loop does not effect the other loops. The control is distributed all over the nodes and there is no centrol loop-controller.

Prenatal ultarsound represents an accurate and reliable method for the detection of intrauterine anomalies, especially urinary tract anomalies. Hydronephrosis is the most common congenital condition detected by prenatal ultrasound. Prenatal ultrasonographic diagnosis allows a good condition and therapeutic assessment of the patients prior to serious impairment of renal function so that in most cases the urological surgeon can opt for a parenchymal conserving procedure. The authors have experienced a case of congenital ureteropelvic obstruction with hydronephrosis diagnosed at 32 weeks of pregnancy and report our experience with a brief review of literature.

제주 지역의 B형 간염 바이러스 유전자형

조지현,박도심,김태현,염주진,김학철,문주현,양재식 대한간학회 2004 Clinical and Molecular Hepatology(대한간학회지) Vol.10 No.1

목적: HBV 감염이 무증상의 자연 회복부터 간경변 혹은 간세포성 간암까지 다양하게 나타나는 요인들로 숙주의 요인과 바이러스의 요인으로 구분되어 제시되는데, 바이러스 요인으로는 감염된 바이러스이 유형이나 염기 변이들이 논의된다. HBV 유형을 구분하는 데는 혈청형과 유전자형이 이용되는데 근자에는 주로 유전자형이 이용된다. 이러한 HBV의 분포는 지역적으로 다르나 지역에 따라서 다른 유형들이 혼재되어 있다. 동남아시아는 B형이지만 극동아시아는 C형으로 알려져 있으며, 대만과 오키나와에서는 B와 C형이 혼재되어 나타난다. 이러한 결과로 미루어 보아 우리 나라의 남부지역에서는 B과 C형이 혼재되어 있을 가능성이 있다. 이에 본 연구는 제주 지역에서 HBV의 유전자형을 조사하고자 하였다. 대상과 방법: 원적지가 제주도이면사, HBsAg가 양성이었던 107명(평균 연령: 46.5세)을 대상으로 하였다. 이들의 혈청으로부터 HBsAg/antiHBe를 분석하고, DNA를 추출하여 7개의 유전자형에 따라 특이성을 갖는 시발체(genotype specific primer)들을 이용하여 PCR로 증폭한 후 이를 분석하였다. 주된 유전자형의 일부와 다른 유형에서 증폭에 이용되었던 시발체를 다르게 이용하여 hemi nested PCR로 증폭한 후 염기를 분석하여 계통발생학적 분석법을 이용하였다. 결과: 1. PCR에 의한 HBV DNA 양성은 107명 중 59명(55.1%)이 양성이었다. HBeAg/anti HBe의 발현 양태에 따라 음성/음성에서 2명(66.7%), 음성/양성에서 30명(41.1%), 양성/음성에서 24명(85.7%), 양성/양성에서는 3명(100%)에서 증폭되었다. 2. Multiplex PCR에서는 58명의 유전자형이 C형, 1명에서는 B형과 C형이 동반 출현하였다. 3. Genotype specific primer를 이용하여 각각 따로 PCR을 시행한 경우에 A형에 의하여 증폭된 예가 1예, B형에 의하여 증폭된 예가 1예, C형에 의하여 증폭된 예가 59예로 A형과 B형 모두가 C형에서 증폭된 예였다. 4. 한 쌍의 시발체에 의하여 증폭되었던 A형과 B형 및 C형의 일부에서 염기를 분석한 결과 모두 C 유전자형이었다. 결론: HBsAg이 양성인 제주 지역 주민의 HBV의 유전자형은 C형일 것으로 생각된다. Background/Aims: Hepatitis B virus (HBV) was classified into 8 genotypes by a sequence divergence in the entire genome designated from A o H. HBV genotypes have distinct geographic distributions. Recently, HBV genotypes have been partially found as influencing the clinical manifestation of chronic liver disease in hosts. In Korea, the distribution of HBV genotypes remains unclear. The aim of this study was to evaluate the prevalence of the HBV genotype on Jeju Island. Methods: Hepatitis B virus genotypes were evaluated among 107 hepatitis B carriers residing on Jeju Island. We used single PCR and multiplex-PCR assay with genotype-specific primer pairs for HBV genotypes A-F for the genotyping. Results: 1. Fifty nine samples (55%) were positive for HBV DNA. The positivity was different according to the pattern of HBeAg/anti-HBe expression, as -/-; 2/3 (66.7%), -/+; 30/73 (30%), +/-; 24/28 (85.7%) and +/+; 3/3 (100%). 2. In the single primer set of genotype-specific PCR, 59 samples (100%) were detected as genotype C and 2 (3%) were also detected as genotype A and B. 3. In multiplex-PCR, 58 samples (98%) were detected as genotype C and only one (2%) as a mixed pattern of genotype B and C. 4. When the PCR products were amplified with universal sense and genotype specific anti-sense from one genotype A, one B, and 2 C, all were included in genotype C. Conclusions: These results suggest that on Juju Island, almost all HBV genotypes are C.(Korean J Hepatol 2004;10:42-50)

수소손상 검출과 평가기술

원순호,현양기,이종오,조경식,이재도 한국비파괴검사학회 2002 한국비파괴검사학회지 Vol.22 No.1

산업현장에서 수소는 설비를 손상시킬 수 있는 주원인 중의 하나이며, 종종 설비를 파괴시키는 사고를 발생시킨다. 수소손상에 의한 결정립계의 공동 또는 미세균열은 강재의 파괴인성과 강도를 떨어뜨리는 원인이 되고, 따라서 과거 제한적인 방법으로 수소손상을 평가하기 위한 시도가 수행되었다. 본 연구에서는 초음파를 적용하여 수소손상을 검출하고 평가하기 위한 연구를 수행하였다. 미세조직시험에 의해 확인된 시험편을 이용하여 초음파의 속도와 감쇠계수를 구한 결과, 수소손상에 의해서 초음파 속도는 감소하고 감쇠는 현저하게 증가하는 것으로 나타났다. 이러한 결과를 바탕으로 수소손상을 검출하기 위한 신뢰성 있는 평가법을 제시하였다. The presence of hydrogen in industrial plants is a source of damage. Hydrogen attack is one such form of degradation and often causing large tube ruptures that necessitate an immediate shutdown. Hydrogen attack may reduce the fracture toughness as well as the strength of steels. This reduction is caused partially by the presence of cavities and microcracks at the grain boundaries. In the past several techniques have been used with limited results. This paper describes the application of an ultrasonic velocity and attenuation in hydrogen damage. Ultrasonic tests showed a decrease in wave velocity and an increase in attenuation. Such results demonstrate the potential for ultrasonic nondestructive testing to quantify damage. Based on this study, reliable recommendation is suggested to detect hydrogen attack.

朝鮮後期 寺刹 寮舍空間의 特性과 變化에 관한 硏究 : 主佛殿 앞마당에 面한 寮舍를 中心으로 Focused on the Yosa faced with the front court of a Central Buddhist Sanctum

김종헌,김도경,양재영 대한건축학회 2003 대한건축학회논문집 Vol.19 No.1

Yosa is a space for organizational living of buddhist monk that is composed of daebang, kitchen, gidaebang, rooms, storages, and so on. The plan of Yosa forms shape of ㅡ,ㄱ,ㄷ,ㅁ. Yosa is organized by practical aspect that is based on living transformation, and each space has its own usual order. Daebang is a centered space that connects the holy space with the mundane space in Yosa. The use and layout of kitchen has intimate relation with constitution of the central space in buddhist temple. As a result of the investigation of the characteristic and transformation of Yosa that is faced with the front court of a central buddhist sanctum, we can understand the space composition principle of the buddhist temple in the Chosun Dynasty. The existing sanctum-centered researches in buddhist temple layout must go side by side with diversified studies.
