본 연구는 클럽 샤프트의 대표적인 재질인 그라파이트(graphite)의 유연한(flexible) 클럽 샤프트(club shaft)의 특성에 따라 피험자가 운동학적(kinematics) 요인이 되는 관절의 각변위, 각속도, 각가속도, 클럽헤드의 속도와 가속도와 같은 변인들이 어떻게 적응하는지 비교 분석하여 보다 효율적인 드라이버 선택에 도움을 주며 샤프트 특성에 따른 신체관절의 움직임에 대한 자료를 제시하고자 하였다. 고속 카메라 2대의 속도는 500fps로 하였고 각 regylar,stiff, x-stiff, 자신의 클럽을 포함 각 4개의 클럽을 사용하여 각 클럽당 3번씩 촬영하였으며 목표방향에서 20m이상 벗어나는 경우의 촬영은 다시 촬영하였다. 본 연구에서는 디지타이징(digitizing)을 신체 9개 마커는 강체로 가정된 클럽과 신체분절 모델로 정의하였으며 2 대의 카메라(500fps)로부터 얻은 avi화일을 컴퓨터에 저장하고 자료로부터 Butterworth 6th order recursive digital filter를 사용하여 1차 자료를 smoothing 하고 DLT를 이용하여 3차원 좌표를 구성하도록 한다. 좌표값을 얻기 위하여 kwon3d v3.0을 이용하였다. 본 실험은 피험자 스스로 클럽의 특성에 따라 스윙의 속도를 달리 하기 때문에 스윙의 시간이 달라지며 어느 정도 클럽이 강성에 따라 스윙시간이 빨라지는 결과로 나타났다. 이것은 피험자가 샤프트가 강성(stiffness)에 따라 스윙 속도를 빨리 하게 되는 원인이 되는 것으로 생각된다. 어깨의 각변위는 클럽이 regular의 경우 임팩트에서 각속도를 계속 유지하고 있으며 stiff, x-stiff의 경우에는 어깨의 움직임이 임팩트에서 급격하게 감소되는 것을 알 수 있다. 이것은 팔의 동작과 클럽의 힘을 크게 하기 위한 동작으로 생각된다. 어깨 각속도는 클럽이 stiff할수록 각속도가 큰 감속하는 것으로 나타났다. 손목속도는 regular 클럽의 경우 손목의 감속이 늦게 되고 임팩트에서 손목의 감속이 적게 하는 것으로 나타났으며 stiff와 x-stiff의 클럽에서 임팩트 시에 순간적인 감가속으로 인해 클럽의 속도를 증가시키고 있다. 임팩트 시에 손목의 감가속은 클럽헤드의 임팩트 시 속도를 증가시키는 결과를 보였다. 클럽헤드는 regular 클럽이 임팩트전에는 속도 증가가 커지는 결과와 일치된 결과를 보이고 있다. The purpose of this study was to find the rational method to analyze golf swing with specific property of club shaft. Three subjects were filmed by two high speed digital cameras with 500fps. The phase analyzed was downswing of each subject. The three-dimensional coordinates of the anatomical landmarks were obtained with motion analysis system Kwon3d 3.0 version and smoothed by lowpass digital filter with cutoff frequency 6Hz. From these data, kinematic and kinetic variables were calculated using Matlab(ver 5.0) The variables for this study were angular velocity and accelerations, which were calculated and following conclusions have been made : 1) Golf swing time of stiff club is faster than that of regular club. 2) In shoulder joint motion of swing with the stiff club, x-stiff showed mort rapid negative acceleration than that of regular club. 3) In regular club, the velocity of club head would be more effective velocity, which was increasing, than those of other clubs before impact. 4) In wrist joint motion of swing with stiff club, x-stiff club showed faster than regular club in the downswing and impact more rapid negative acceleration.

목적 : 항암화학요법 중 호중구감소증을 동반한 발열이 발생하는 암환자들을 치료하기 위한 다양한 항균제와 여러 가지 방법들이 시도되고 있는 가운데, 합병증과 사망률의 발생가능성이 적은 저위험군 환자들을 대상으로 초기 72시간동안 정주 항균제를 투여한 이후 경구 항균제로 전환하는 요법의 유용성과 안정성을 평가해보고자 본 연구를 시행하였다. 방법 : 1998년 2월부터 1999년 9월까지 본원에서 항암화학요법 중 호중구감소증과 발열이 발생한 환자들 가운데 기저 암질환이 고형암이거나 림프종이고, 입원당시 패혈증의 증후가 없으며 입원 72시간이내에 해열되고 백혈구수치가 증가 추세인 환자들을 대상으로 하여 72시간 동안 정주 항균제를 투여한 이후 경우 ciprofloxacin 750㎎을 하루 2회씩 투여하여 총 4일간 투여하였다. 모든 환자들은 열이 떨어지고 호중구감소증이 회복될 때까지 입원하도록 하였다. 결과 : 총 38명 환자의 40예가 등록이 되었고, 환자들의 기저암 질환은 고형함이 72.5%, 림프종이 27.5%였다. 입원당시 평균 호중구치수는 156/㎕였고, 호중구수치가 100/㎕미만인 경우는 65%였으며, 호중구감소증이 지속된 기간의 평균은 2.4일이었다. 40예 중 39예가 항균제의 변형이나 추가 없이 호중구감소증과 발열로부터 회복이 되어 97.5%의 성공율(95% 신뢰구간: 86.8-99.9%)을 보였다. 부작용으로 피부발진이 있었던 경우가 한 예 있었는데, 증상이 경하여 경구 항균제를 지속할 수 있었다. 심와부의 동통으로 복용을 지속할 수 없어서 대상에서 제외된 예가 또 한 예 있었다. 결론 : 항암요법 중 호중구감소증과 발열을 동반한 환자들 가운데 저위험군 환자들에서 항균제 72시간정주 이후 경구 항균제로의 전환요법은 효과적이고도 안전한 치료방법이라고 할 수 있다. Background : Oral antibiotic therapy following empirical intravenous antibiotics may be effective and safe for febrile neutropenic patients with lowrisk for complications. Methods : We conducted a prospective clinical trial of oral antibiotic therapy in the patients with neutropenia and fever during chemotherapy for cancer. Underlying malignancies were solid tumor or lymphoma with short duration of neurtropenia and the patients had no evidence of clinically or microbiologically documented infections. Oral ciprofloxacin was given to the patients who lacked signs of sepsis on admission, had a rising tendency of neutrophil count (ANC >100 /㎕ ) at 72 hours, and were afebrile at 72 hours. All patients were hospitalized until neutropenia and fever resolved. Results : A total of 40 episodes of 38 patients were enrolled from February 1998 to September 1999. The mean neutrophil counts on admission were 156/㎕ and the mean duration of neutropenia was 2.4 days. The episodes which had neutrophil count below 100 /㎕ were 26 (65%). Treatment was successful in 39 of 40 episodes (97.5% : 95 % confidence interval, 86.8% to 99.9%). Adverse reactions of oral ciprofloxacin were skin rash and epigastric soreness in two cases, respectively. There were no deaths during the study. Conclusions : For low-risk febrile patients with neutropenia during cancer chemotherapy, switch therapy to oral ciprofloxacin at 72 hours following intravenous broad-spectrum antibiotics is effective and safe,

Diabetic foot infection is one of the important complications in patients with advanced diabetes mellitus. Limb threatening infections such as osteomyelitis, abscess, and necrotizing fasciitis are frequently accompanied by the disease. Non-tuberculous mycobacterium (NTM) is a rare causative organism of diabetic foot infection. Thus, if one is not suspicious or meticulous, infection due to NTM will be easily overlooked and this will result in delayed diagnose and treat. Therefore, it is necessary to consider NTM as the causative organism if the wound does not respond to the conventional antibiotic treatment and the culture from the adequately obtained specimen reveals atypical acid-fast bacilli. We present a case of diabetic foot infection with osteomyelitis and abscess due to Mycobacterium mageritense, one of the rapid growing mycobacteria, that was successfully treated with surgical debridement and appropriate antibiotic treatment.
