C. fetus 심내막염은 드물게 발생하는 질환으로 주로 면역능이 저하된 환자에서 발병하고 대동맥판을 침범하는 경우가 많으며 적절한 치료가 되지 않을 경우 치사율이 높다. 저자들은 기저질환이 없던 69세 남자에서 C. fetus 심내막염을 경험하였기에 문헌고찰과 함께 보고하는 바이다. 환자는 발열로 내원하여 시행한 혈액배양 검사상 C. fetus가 동정되었고 경식도 초음파 검사상 삼첨판에 증식증이 발견되어 심내막염 진단하에 ceftriaxone에 이어 meropenem으로 총 4주간 항생제를 투여받고 호전되었다가 한달 후 다시 재발하였고 판막부전 소견 진행하여 삼첨판 치환술을 시행받고 전신상태 호전되어 퇴원하였다. Campylobacter fetus is a rare cause of endocarditis. To date, only about 30 cases of C. fetus endocarditis have been reported mainly in the elderly with chronic underlying illnesses. Most cases showed tendency to involve aortic valve. This report describes a case of native tricuspid valve infective endocarditis in a 69-year-old man without any underlying disease. Despite adequate antibiotic therapy for 4-weeks, endocarditis recurred and leading to surgical valve replacement.

A posterolateral intertransverse process fusion is generally considered to be one of the most common types of lumbar fusion and a reliable procedure. It is reported that establishment of blood supply is important for nutrition as well as for formation of new bone during bone graft healing. Since the major interosseous blood supply for vascularization of autogenous bone graft is originated from the upper and lower transverse process, the one of the transverse process can he related to rate of bony union. It can be constructed that different union rate can result from the differences in transverse process areas. In this study, the area of the transverse processes of L5 were measured in normal adult. For this purpose, Ushikata area-Curvimeter (X-PLAN 360) was used. In Results, there was no significant differences in the age, but there was differences in the gender.

In any rapid prototyping process, the layer by layer building process introduces an area error between the staircase and the surface line specified by the computer-aided design model. This affects the dimensional accuracy as well as the surface finish for different part build orientations. This paper describes a methodology for computing the area error for any orientation of the part built by the fused deposition modelling system. This technique can be applied to determine the best build orientation of the part, based on the minimum area error. This technique is verified by comparing the results with the experimental measurements of the area error of the parts built at different orientations.
소재 관련업체 및 기관과 신소재연구소의 상호 정보교환 시스템 구축

현재 국내 부품소재 산업은 제조업 총 생산액의 약 30%를 차지하는 주요산업이며, 향후 그 규모가 확대될 전망이다. 그러나, 산학간의 관계에 있어서는 상대방에 대한 정보가 제한되어 있기 때문에 중소기업의 애로기술을 해결하기 위한 산학협동이 어려운 실정이다. 따라서 경남대학교 신소재연구소에서는 산학간의 정보교환을 원활하게 하고 중소기업의 애로기술을 해결하고자 부품소재관련 전문 홈페이지를 구축하였다. 본 연구에서는 중소기업 및 경남대학교의 구성원이 신소재연구소의 홈페이지를 쉽게 사용할 수 있도록 홈페이지의 내용을 설명하고자 한다. Currently, parts and materials industry is the major part of the domestic manufacturing industry occupying 30% of the market and the share is expected to increasingly grow. However, as far as the relationship between the industry and the university is concerned, it is very difficult to develop an industry-university cooperation to solve a technological difficulties of the medium and small sized enterprises because of the limited amount of informations between them. Therefore, a homepage for parts and materials has been constructed in the Institute for Advanced Materials in Kyungnam University to facilitate free exchange of informations between industry and university and to solve technological difficulties of the industry. In this study, the contents of the homepage are introduced in detail for the users in the medium and small sized enterprises and Kyungnam University.

This study investigates the influence of cane length on the weight distribution of the elderly in a standing position. Thirsty participants were evaluated using two different cane lengths based on measurements of distal wrist crease to ground (WC cane), and distance of greater trochanter to ground (GT cane). A limloader was used to determine the weight distribution on the subject. It was found that 6.5% of body weight was supported on a GT cane and 7.7% of body weight supported on a WC cane in a standing position. Results suggests that more weight is distributed on a WC cane than a GT cane in the elderly.
수평/수직 보간법을 이용한 계층적 영상 부호화에 관한 연구
송영준,안재형 충북대학교 컴퓨터 정보통신 연구소 1999 컴퓨터정보통신연구 Vol.7 No.1
본 연구에서는 보간법을 사용한 계층적 부호화의 성능을 개선시키기 위하여 기존의 보간법인 선형 보간법 대신에 수평/수직 보간법을 제안하고 그 성능을 분석하였다. 수평/수직 보간법은 윤곽선을 정확히 예측하기 위하여 Zschunke에 의해 제안된 비선형 예측 방법을 응용한 것으로 윤관선의 방향에 따라 보간 방법을 수평 또는 수직 방향으로 선택하여 행하는 방법이다. 제안된 방법이 선형 보간법보다 MOS(Mean Option Score)로 0 레벨에서 0.5의 화질 개선치를 보였다. This paper proposed a nonlinear interpolation method to improve the quality of reconstructed images for the hierarchical interpolation (HINT) coding. Its method is horizontal or vertical interpolation according to boundary direction. The proposed interpolation method gives better image quality than the linear interpolation. The results by subjective tests show that the MOS value for the reconstructed image using the horizontal/vertical interpolation is about 0.5 higher than using the linear interpolation at the level-zero hierarchy.

Background : In recent years gonorrhoea has been panendemic and remains one of the most common Sexually Transmitted Diseases in the world, especially in developing countries. Objective & Method : For the detection of a more effective therapeutic regimen and assessing the prevalence of Penicillinase Producing Neisseria Gonorrhoeae(PPNG), Ive have been trying to study the patients who have visited the VD Clinic of Choong-Ku Public Health Center in Seoul since 1980 by means of the chromogenic cephalosporin method. Results : In 1994, 168 strains of N. gonorrhoeae were isolated, among which 109 (64,9% ) were PPNG. Conclustion : Our results suggests that the prevalence of PPNG in Seoul is still increasing.
