Percutaneous Cannulated Screws with Tension Band Wiring Technique in Patella Fractures

조진호 대한슬관절학회 2013 대한슬관절학회지 Vol.25 No.4

Introduction: Most patellar fractures are transverse involving the central third. Open reduction and stabilization of transverse patellar fractures is indicated if there is more than 2–3 mm of fragment separation and/or articular incongruity. Surgical Technique: This study describes a percutaneous 2 cannulated screws and modified tension band wiring technique to treat transverse patellar fractures. Materials and Methods: We performed 30 cases of displaced transverse patellar fractures with this technique. The clinical outcomes of these patients were evaluated with simple radiographs, range of motion and Lyshom score. Results: This technique has shown to provide satisfactory clinical results and excellent knee functions.Conclusions: This technique provide stable fixation, allows early motion exercise by minimizing injury to extensor mechanism and reduce cosmetic problem in scar.

Wireless Transmission Method for VGA Capsule Endoscopy Using Manchester Encoding

조진호,이정현 대한의용생체공학회 2013 Biomedical Engineering Letters (BMEL) Vol.3 No.4

Purpose Recently, technologies related to endoscopes havebeen rapidly developing with the improvements in electronicsand MEMS technology. The human intestine is very longand twisted, and traditional wired endoscopes are able tomonitor the entire intestine except for the small intestine. Toovercome the limited view of wired endoscopes, the capsuleendoscope has been developed. There are some commercialcapsule endoscopes and others under development, but thesecapsule endoscopes have been limited to CIF images, andthe image transmission rate is 2 frames per second. To obtainhigh-quality images, fast wireless communication technologyis needed. Methods In this paper, the direct transmission of distalimages through Manchester code and its receiving algorithmare proposed to obtain endoscope images with higher qualityand faster transmission rate than with conventional capsuleendoscopes. Generally, the baseband signal cannot be radiatedfrom an antenna because of its large bandwidth and lowfrequency band, but the Manchester code can solve theseproblems. To validate the proposed wireless transmissionmethod and its receiving algorithm, computer simulationsand experiments have been performed. Results Experimental results verify that the proposed wirelesstransmission method can transmit VGA-grade images of 640× 480 pixels with a faster frame rate of about 3 frames persecond compared to conventional capsule endoscope methods. Conclusions Therefore, it is expected that the proposed VGA transmission method can be applied to improve theperformance of capsule endoscopes.

Chemical and Electrochemical Intercalation of Lithium in 2D-FeMoO$_4Cl^1$

조진호,장순호,노동윤,손경아,Choy Jin-Ho,Chang Soon-Ho,Noh Dong-Youn,Son Kyoung-A Korean Chemical Society 1989 Bulletin of the Korean Chemical Society Vol.10 No.1

Lithium has been intercalated into $FeMoO_4Cl$, and deintercalated from $LixFeMoO_4Cl$ both electrochemically and chemically. The inserted $Li^+$ ions are stabilized in the distorted octahedral field in interlayer space of $FeMoO_4Cl$. The crystal symmetry is reduced from tetragonal to monoclinic due to the reduction of ferric to ferrous ions in $LixFeMoO_4Cl$ upon lithium intercalation. From the magnetic and structural data, it has been concluded that the high-spin electronic configuration of $Fe^{2+}(d_{xz}^2{d_{y2}^1}{d_1}{2d_z^12}{\cdot}_y2)$, corresponding to $^5E_g$, group term in $D_{4h}$ symmetry, can be stabilized by the elongation of $FeO_4Cl_{2-}$octahedra in a weak ligand field.

The authors represented an analysis on 10 patients with traumatic epidural hematomas of the posterior fossa who had been treated successfully from January 1984 to October 1985. The result were summarized as follows; 1) Age incidence comprised ranging from 4 to 62 years and 6 were males and 4 were females. 2) Site of hematoma was related with fracture site closely and bleeding source confirmed during operation was transverse sinus in 4 cases, occipital sinus in 1 case, fracture site in 3 cases and unknown in 2 cases and it had close relationship between fracture site and large venous sinus. 3) Outcome was good in most cases except death in I and moderate disability in I case. Factors contributing to outcome were early detection and adequate treatment and also associated supratentorial injury.

고령의 환자에서 발생한 스테로이드 유발성 골괴사증 : 1예 보고 A Case Report

조진호,오형근 白中央醫療院 2004 仁濟醫學 Vol.25 No.1

Steroid induced osteonecrosis of the knee is a relatively uncommon disease and occurs primarily in patients younger than 50 years of age with immunocompromising disorders. Compared with spontaneous osteonecrosis, steroid induced osteonecrosis produces a more diffuse pattern of bone necrosis and frequently occurs in bilaterally. Although other treatment modalities have been reported, total knee arthroplasty can be considered as a successful procedure for steroid induced osteonecrosis. We encountered the case of 69 year old female who was diagnosed as bilateral steroid induced osteonecrosis of the knee without underlying immunocompromised disorders.

지상파 디지털 TV 송수신시스템의 성능분석

조진호,노석호 安東大學校 工業技術硏究所 2001 공업기술연구논문집 Vol.8 No.1

우리나라는 2001년도부터 지상과 DTV (digital television)방송을 시작하기로 되어있으며, 이의 성공여부에 따라 기존의 아날로그 지상과 TV 방송을 2006년까지 점진적으로 디지털방송으로 전환할 계획이다. 한국전자통신연구원에서는 ATSC규격을 만족하는 지상파DTV 시스템을 1998년부터 개발하고 있으며, 이의 성능을 검증하기 위하여 대전광역시에 있는 약 33개 지점에서 현장 수신시험을 실시하였다. 현장 수신시험에서는 각 지점의 수신감도를 측정하고 신호 및 잡음전력의 크기를 비롯하여 SER (segment error rate), 등화기의 탭 에너지 (tap energy) 등 각종 수신 파라미터를 측정하여 송수신시스템간의 설계규격을 만족하는지 분석하였다. 측정결과 절반이상의 수신지점에서 양호한 비디오와 오디오 품질이 얻어졌으며, 등기화의 작동으로 고스트 현상을 감소시켜 입출력 신호 대 잡음비가 13.7㏈까지 개선되었다. Korea has plan to start terrestrial DTV broadcasting in 2001 and all analog TV broadcasting will be changed to digital until 2006. ETRI developed the first ATSC compliant terrestrial DTV system in 1998. DTV system is under field trial with broadcasting company. This paper presents analysis of terrestrial DTV field trial results over Daejon city area. Thirty three points were selected as measuring point. Signal power, noise power, Segment Error Rate and equalizer performance was measured. DTV video and audio quality were good over half of test sites. Equalizer could correct signal ghost and improve S/N up to 13.7 dB.
