Syphilis is a systemic infectious disease infected by the spirochete Treponema pallidum. It shows variable clinical manifestations. Nephrotic syndrome from secondary syphilis is a rare complication in Korea. One letter was reported before in Korea. This report describes 64-year-old male patient with syphilis presented with feature of hepatitis, acute renal failure and nephrotic syndrome. A diagnosis of secondary syphilis was done by the serologic test for syphilis. After diagnosis of syphilis, we supposed that nephrotic syndrome and hepatitis were the complication of secondary syphilis and performed a kidney biopsy. A kidney biopsy revealed membranous nephropathy characterized by subepithelial deposits involving the glomerular basement membrane and effacement of epithelial foot-process on electron microscopy. The patient was treated with intramuscular benzathine penicillin 2.4 million units. Proteinuria, renal failure, hepatitis were resolved in 3 weeks after penicillin therapy.

Spinal epidural abscess is an uncommon but readily diagnosable and treatable potential cause of paralysis and death. The incidence of spinal epidural abscess is approximately one to two cases per 10,000 hospital admissions in the United States. The symptoms of spinal epidural abscess are varied but include lower back pain, fever, local tenderness and neurological deficit, especially in such high risk groups as patients with diabetes, intravenous drug abuse, chronic renal failure, alcoholism, liver disease and immunocompromization. Infections of the epidural space originate from contiguous spread or via hematogenous routes from a distant source. Cutaneous sites of infection are the most common remote sources, especially in intravenous drug users. S. aureus accounts for most spinal epidural abscess infections, followed by streptococci and gram-negative anaerobes. We here report a case of spinal epidural abscess in renal abscess patient complaining of fever and back pain. A 71-year old female patient was admitted to epigastric pain and oliguria. She had been diagnosed as acute renal failure and treated with hydration. After third hospital days, she shows a persistent fever and drowsy mentality. Abdominal computed tomography demonstrated renal abscess. She was treated with intravenous antibiotics, third cephalosporin. Blood cultures and urinary culture revealed Escherichia, coli. After fourteenth hospital days, she developed back pain, muscle weakness and decreased sensation of lower extremities. Spine MRI demonstrated spinal epidural abscess with spinal cord compression. Surgical drainage with laminectomy was performed. After treatment of intravenous antibiotics and surgical drainage, she discharged with improved back pain and neurological symptom.

CT시편의 구속효과가 파괴저항곡선에 미치는 영향

우홍식,김수용 동국대학교 경주대학 1997 東國論集 Vol.16 No.1

In order to obtain more realistic fracture resistance curve, many researchs are currently underway to introduce new parameter and to quantify the constraint effect. The objective of this paper is to investigate the relationship between the crack tip constraint effect (specimen size, specimen thickness, plane size, crack length ratio and side groove) and the fracture resistance curve. In this paper, fracture toughness tests were performed with various parameters. Test results show that the J-R curve is increased with increase in the plane size and decrease in the crack length and the J-R curve is decreased due to the side groove of specimen. In addition to the effects of the crack length and the plane size on the J-R curve are significant while the effects of specimen thickness and the specimen size on the J-R curve are insignificant.

MERCOSUR 창설배경

김흥수 서울大學校 스페인中南美硏究所 1995 이베로아메리카硏究 Vol.6 No.-

In preparing the presentation for "The Background Accounts of the Process for the Formation of MERCOSUR, the Southern Cone Common Market" the writer tries to deal with the subject not with an in-depth academic point of view, but more based on the personal experiences and observations attained during the writer's diplomatic assignments in the countries comprising MERCOSUR, namely Brazil, Uruguay, and Paraguay. During his tenure in Paraguay, the writer was able to attend the MERCOSUR conference held in Asuncion, Paraguay in 1991. Therefore, the presentation focuses on the general atmosphere surrounding the process of economic integration within the Southern Cone of the South American continent and a short geopolitical review related with the integration. Following the end of the cold war, countries around the world have been forming regional trading arrangements and intensifying existing ones at a rapid pace. The global trend has shifted more towards regionalism, bringing forth the emergence of the European Union. NAFTA, and the rapid development of APEC in the asian Pacific region. Such rapid formation of regional trading arrangements prompted the southern Cone countries into reshaping their regional economic arrangements, leading towards the creation of MERCOSUR. In the beginning, Brazil and Argentina were involved but later on Uruguay and Paraguay were invited to join them. The southern Cone Common Market occupies a land area of approximately 12,000,000km, which is much larger than the entire E.U. countries combined. It boasts a combined GDP of US$ 483 billion, a population of 200 million and US$ 100 billion in trade. The land is very rich in natural resources, with the greater part of the area still intact from exploitation. The mineral and agricultural areas top the world ranking in production, especially in grain production. The region may well plat a principal role as the world's bread basket in the 21st century. In 1991 the leaders of four Southern Cone nations, Brasil, Argentina, Uruguay, and paraguay, met together in Asuncion, the city of paraguay, for the signing of the MERCOSUR treaty. The four heads of state were much elated by the recent wave of democracy sweeping the region and the resulting positive international attention surrounding the return of democracy to their nations. Democratic stability enabled these countries to overcome chronically high inflation rates and achieve some degree of economic stability, which contributed to the return of foreign capital. Confident of their newly found economic and political stability, they called for joint efforts to pave the way towards sustained economic development in order to guarantee the longevity of their democratic governments, reduce foreign debt, increase the level of private investment in the MERCOSUR, and eventually establish a hemispheric free-trade zone. The treaty meeting proceeded with a very different atmosphere very much unlike earlier conferences or meetings. It used to be that such meetings between the hemispheric nations were often filled with rhetoric replete with prolonged speeches not related with that meeting. This time, the meetings started on time and no rhetoric nor unnecessary long vague words. The four countries are proud of their independence heroes, Simon Bolivar and San Martin, two men who were ardent advocates of internationalism and called for Latin American integration as early as the beginning of 19th century. The Pan American Union was created well before the League of Nations and later the United Nations. The economic potential and spirit of internationalism of the MERCOSUR countries helped pave the way for inter-American cooperation. It is not only for the integration but also to be in a better position for future negotiation in economic and trade with E.U., NAFTA, and APEC. In viewing the Korea-Latin America economic relations, especially with the MERCOSUR countries, there are some important facts which the Korean side should take into consideration. First, the economic potential and favorable geopolitic standing of MERCOSUR will play a very important role as a bridge-head for the increased trade and economic cooperation with E.U. and NAFTA. Lastly the establishment and maintenance of positive economic cooperation are encouraged for further development in the mutual interest and benefit.

전자상거래 보안의 전망과 방향

박수범,최항묵,최흥국 인제대학교 1999 仁濟論叢 Vol.14 No.3

인터넷과 통신매체의 확산과 더불어 최근에는 기업간, 기업과 정부간에 주로 정형적인 문서교환에 활용되던 초기의 EDI(Electronic Data Interchange)가 멀티미디어 정보교환이 가능한 인터넷의 보급 확산과 함께 소비자를 대상으로 하는 전자상거래(EC : Electronic Commerce)로 급속히 확산되고 있으며, 이를 지원하기 위해 기업의 정보화 기반을 구현하는 ERP(Enterprise Resource Planning)도 요구되고 있다. 이미 전세계적으로 수만개의 쇼핑몰이 들어서 있으며, 새로운 전자상거래 적용 사이트가 계속해서 생기고 있으며, 이들 사이트마다 제각각 자신들의 아이템을 화려한 멀티미디어적인 요소로 선전하며 소비자를 기다린다. 그러나, 전자상거래는 네트워크를 통하여 형성되므로 사용자들은 서로 만나지 않고 거래하게 된다. 이는 전자상거래의 장점이기도 하지만, 반대로 상호간의 신분에 대한 인증이 쉽지 않다는 단점이 된다. 본 논문에서는 이러한 위험을 방지하기 위한 암호화 인증 기술들에 대한 최근까지의 표준들을 기반으로 논의하고자 한다. Recently, early EDI(Electronic Bata Exchange), which used to exchange formal documents among enterprises including government, is getting changed into EC(Electronic Commerce) because of rapid propagation of the Internet that can make it possible to exchange multimedia information for consumers. In addition to, ERP(Enterprise Resource Planning) is getting improved to support what I mentioned above. Already there are millions of shopping malls through the world and newly web sites for EC are getting emerged advertising their own items using multimedia technology and Unfortunately, As everbody knows, EC is made through Network so users do not have to meet one another to deal. This fact can be an advantage. However it can be a disadvantage because it is not easy to make sure the authentication of private ID's for each other. This paper would like go through "Encryption Authentication Technology" to discuss these disadvantages.

러시아어 용어체계에서 외래용어의 차용과 정리 문제

임흥수 조선대학교 인문학연구소 1997 外國文化硏究 Vol.20 No.2

현대 러시아어의 차용 및 차용어(외래어)에 관한 연구는 다른 분야에 비해서는 많지 않지만, 연구 범위 면에서는 각종 차용어의 종류별 연구, 차용어의 순화와 동화, 수용언어(외래어를 받아들이는 언어)의 체계에 미치는 차용어의 영향에 관한 연구 등 비교적 광범위한 편이다. 여기서 주목할 점은 용어의 차용 과정은 일반 어휘의 차용 과정과 크게 다르지 않으며, 실제로 대부분의 차용은 용어에서 발생한다는 사실이다. 따라서 전반적인 차용에 관한 연구 문헌의 내용들을 용어의 차용에 적용하여도 무방하다 할 수 있다.

우흥식,강봉수,김봉철 東國大學校 1999 東國論叢 Vol.38 No.-

Fatigue crack growth behaviour of Ti-alloy, Ti-6Al-4V were investigated in air and salt corrosive environments. The temperatures which was tested were room temperature and 200℃. Fatigue crack growth rate is known to be fast for formation of corrosive product by impregnation Ti-Alloy with salt solution in hot salt environment. For the effect on corrosion fatigue crack growth behabiour of sale corrosive transformation in air and high temperature of region Ⅱ, fatigue crack grwoth rate in air atmosphere had a little gap to both case, 200℃ and room temperature. However, it showed very fast tendency especially in salt corrosive atmosphere, and it was remarkably accelerated in 200℃ high temperature salt environment. When ΔK was approximately 30MPa√m, fatigue crack growth rate had a little difference between at room temperature and at 200℃ high temperature, however in case of salt corrosive environment, the former was 3.5 times faster and the latter for 16 times than air environment respectively. For salt corrosive environment of microstructure (Ⅲ), the fatigue life in 200℃ salt corrosive environment was shorter than that of in air, reached to only 32%.
