본 논문에서는 기존의 광학식 모션 캡처에서 생길 수 있는 마커들 간의 간섭이나 복잡한 시스템 구성으로 인한 시스템 설치의 복잡성 문제들을 해결하기 위해, 2차원 위치정보를 제공하는 단일 카메라와 특정부위의 방향정보를 제공하는 가속도센서와 자이로 센서로 구성된 동작센서를 융합하여 간편한 모션 캡처를 실현하는 새로운 기법을 제안한다. 본 논문의 동작 인식은 크게 영상기반 위치 정보와 동작센서기반 방향 정보의 융합을 통해 이루어진다. 영상은 보이는 부위에 장착된 컬러마커의 위치를 기준점으로 제공하고, 동작센서들은 각 패지의 이동방향과 속도를 측정하여 영상에서 제공하는 마커들의 3차원 포즈정보를 알아 낼 수 있다. 제안하는 시스템은 사람동작의 측정에 필요한 최소한의 센서정보를 사용함으로써 시스템의 구성과 센서의 설치가 매우 간단하며 경제적이라는 장점을 갖는다. 이러한 장점은 다양한 실험을 통해 검증하였다. At the aim of solving the problems appearing in traditional optical motion capturing systems such as the interference among multiple patches and the complexity of sensor and patch allocations, this paper proposes a new motion capturing system which is composed of a single camera and multiple motion sensors. A motion sensor is consisted of an acceleration sensor and a gyro sensor to detect the motion of a patched body and the orientation (roll, pitch, and yaw) of the motion, respectively. Although Image information provides the positions of the patches in 2D, the orientation information of the patch motions acquired by the motion sensors can generate 3D pose of the patches using simple equations. Since the proposed system uses the minimum number of sensors to detect the relative pose of a patch, it is easy to install on a moving body and can be economically used for various applications. The performance and the advantages of the proposed system have been proved by the experiments.

Background: Post-pneumonectomy empyema(PPE) is an uncommon but a serious complication. The management remains as challenge for general thoracic surgeons. Material and Method: During the period of January 1990 to December 1996, we evaluated the results of 20 patients with post-pneumonectomy empyema. Result: Sex ratio were 15 male and 5 female patients with mean age of 41.5${\pm}$21.5 yrs. The occurrence ratio of left to right side was 8:12. The most common disease for prior pneumonectomy was pulmonary tuberculosis. The duration between pneumonectomy and PPE was variable in 1 month to 6yrs. Fever was the most frequent symptom and S. aureus was the most frequent pathogen. In 13 cases, there were combined with BPF. Four patients underwent trans-sternal closure, and Clagett procedure was performed. There was one recurrence that later underwent muscle plombage and omentopexy later. Nine patients underwent omentopexy, muscle plombage and thoracoplasty. There were 7 cases that were not combined with BPF. All 7 patients underwent thoracoplasty, and two of them were combined with muscle plombage. Mean follow-up duration is 40${\pm}$32.3 months. There were no late deaths nor recurrences of PPE. Conclusion: We conclude that early diagnosis and proper drainage in PPE patients are important in its initial stage of management, and also management is completely achieved in thoracoplasty with muscle plombage or omentopexy. 배경: 전폐절제술후 발생한 농흉은 흔하지는 않지만 심각한 합병증을 유발할 수 있다. 그리고 치료는 아직 흉부외과 의사에게 문제로 남아있다. 대상과 방법: 1990년 1월부터 1996년 12월 까지 전폐절제술후 발생한 농흉환자 20례를 분석하였다. 결과: 성별비는 남자가 15명, 여자가 5명 이였으며, 평균 연령은 41.5$\pm$21.5세였다. 좌우비는 8:12였고, 선행질환으로는 폐결핵이 가장 많았다. 폐절제후 농흉이 발생하기 까지의 기간은 1개월에서 6년까지 다양하였다. 가장 흔한 증상은 발열이였고, 포도상구균이 가장 흔한 원인균이였다. 13례에서 기관지 늑막루를 동반하였으며 4명의 환자는 전경심막을 통하여 기관지 절주를 봉합한 후 Clagett 술식을 시행하였고, 그 중 한명은 재발하여 후에 대망과 근육을 이용하여 흉곽 성형술을 받았다. 나머지 9명의 환자에게는 대망과 근육을 이용한 흉곽 성형술을 실시하였다. 기관지 늑막루를 동반하지 않은 7례에서는 모두 흉곽성형술을 실시하였고 이중 2례에서는 근육 충진법을 같이 시행하였다. 평균 추적 기간은 40$\pm$32.3개월 이였다. 사망과 재발은 발생하지 않았다. 결론: 전폐절제술후 발생한 농흉 환자에 있어서 조기 진단과 적절한 배농이 일차적 처치로서 중요하며, 흉곽 성형술과 더불어 대망이나 근육 충진법으로 완전한 치료가 가능하다.

Among elevn consecutive cases having undergone Completion Pueumonectomy[CP]between 1958 and Aug. 1993 at the Dep. of Thoracic & Cardiovascular Surgery in National Medical Center. The patient`s mean age was 43 years[range 28 yrs, to 68yrs.],& they consisted with 10 males and 1 female. The indications for CP were benign diseases in 9 cases & 2 cases of lung cancer. The mean interval between the first operation & CP was 62.3 months[from 17 days to 288 months]. The several special intraoperative procedures such as intrapericardial pulmonary vesselsdivision & suture ligation, reinforcement of bronchial stumpmargin, & applied the Fibrin glue & hemostatics. The mean intra operative bleeding was 3582ml.[1500ml. to 6500ml.] The post orerative complication were developed in 5 cases[45.5%] they were empyema with BPF in 2 cases, empyema in 2 cases, & 1 case of repiratoy insufficiency which leading to death. We concluded that the C P noted high morbidity & mortality compared with ordinary first pulmonary resectional surgery. But, it will be a challenge to improved the morbidity because of increasing trend of completion pneumonectomy in a furture time.

The spontaneous pneumothorax occurs subsequent to a disruption in the continuity of the visceral pleura with escape of free air into the pleural space included primary & secondary pneumothorax that is unrelated to identifiable etiologies such as trauma. In. the 33 year period 1960 to 1993, the 230 cases of open thoracotomy were carried out for definitive treatment of spontaneous pneumothorax, at the Dept. of Thoracic & Cardiovascular Surgery, National Medical Center, Seoul, Korea. There were 193 men & 37 women. They ranged in age from 15 years old to 72 years old. The lesion site was on the right side in 117 and on the left in 97, the 16 cases were in bilateral lesions.Surgical indications included recurrence in 98 cases, persistent air leak in 68 cases, nonexpansion of the lung 37 cases, roentgenologically apparent bullae & blebs in 23 cases, bilateral lesions in 16 cases,combined hemothorax & prevent for recurrence in each 2 cases. The types of operation were bullectomy in 207 cases, wedge resection in 13 cases, decortication & B.P.F. closure in 6 cases,lobectomy in 2 cases, pneumonectomy, plication in each I case. The post operative complication developed in 18 cases[7.8 %], there was I case of death due to sepsis. We believed that open thoracotomy with resection or obliteration of blebs & pleurodes is provided the best protection against recurrence.

N/A Background: Since initial treatment for complete heart block with external transvenous pacemaker by Zoll in 1952, the frequency of the use for cardic pacing has increased considerably and the indications for long term pacing have greatly extended according to the development of smaller and multiprogrammable pacemakers. Complications related to cardic pacemaker have also been diversified. Method: To examine complications related to them, we studied 59 implantations of permanent pacemaker from January 1986 to October 1992 at National Medical Center. Results: 1n this study we experienced 16 cases (27.1%) of complications for cardiac pacing in 59 implantations of permenent pacemaker. They included two cases (12.5%) of pacing failure, two cases (12.5%) of undersensing of wide QRS wave, one ease (6.3%) of undersensing of APC, one case (6.3%) of dislodgement, three cases (18.8%) of oversensing, two cases (12.5%) of pacemaker induced CHF, three cases (18.8%) of competition and two cases (12.5%) of wound infection. Conclusion: With more frequent use of permanent pacemaker, it is thought that the development of ideal pacemaker is required.
