중 저준위 방사성폐기물의 처분/폐쇄 이후 기체 발생특성을 실질적으로 평가하고, 이를 이용하여 발생 기체의 종합관리방안을 수립하기 위해서는 실제 처분환경 및 특성을 고려한 장기간의 실증실험이 반드시 필요하다. 이와 관련하여, 국내에서는 월성원자력환경관리센터의 1단계 10만 드럼 처분에 대한 건설 및 운영허가 후속조치의 일환으로 현장부지에 기체발생 실증실험시설이 설치/운영될 예정이다. 이에 대한 기초자료를 확보하기 위해, 세계 각국에서 다양한 방법으로 수행된 기체 발생 관련실험에 대한 제반사항을 면밀히 검토하였다. 그 결과 우리나라와 처분방식이 동일하며, 실제 폐기물 포장드럼 및 기본 처분단위를 이용하여 대규모로 수행된 핀란드의 기체 발생 실험자료를 국내 실증실험에 대한 유용한 벤치마크로 사용할 수 있을 것으로 판단된다.

본 논문은 다중출력 스위칭-모드 전원 공급 장치에서 변압기 2차 측의 출력전압 안정을 위하여, 일반적으로 사용하는 선형 전압조절기의 피드백 보상기의 제어신호를 이용하여 부하 전류정보를 측정하고, 모든 부하가 경부하 상태일 경우에만 대기전력 모드로 동작하도록 하였다. 기존 방식은 주제어기 출력의 부하상태에만 의존하여, 나머지 2차측 출력의 부하상태와 상관없이 대기전력을 저감하기 위한 간헐 스위칭 모드 (burst mode) 제어로 들어가는 문제가 있다. 기존의 전류센서 혹은 저항을 이용하여 부하전류 정보를 얻는 방식이 아닌 선형전압 조절기를 이용하여 시스템을 저가격화 하였으며 모든 출력이 경부하일 경우에만 대기모드로 전환 하도록 하여 출력전압의 신뢰성을 향상시켰다. 본 논문에서는 제안된 제어기 회로의 동작원리를 설명하고 시뮬레이션으로 검증 하였으며 25W급 하드웨어를 구현하여 제안된 회로를 검증한다.

Purpose: The purpose of this study is to examine the effects of sensorimotor training on knee joint stability after anterior cruciate ligament reconstruction. Methods: The subjects were sixteen 16 adults who received anterior cruciate reconstruction by arthroscopy, and underwent sensorimotor training for which was to have them maintenanceain of a standing position with a step Balance ball on the affected side over 30 degrees knee flexion with 100% weight bearing for 15-20 seconds. Before the genuine experiment commenced, the Lysholm scale was had been used to assess functional disorders on the affected knee joint. KT-2000 Arthrometer measurement equipment was used to measure anterior displacement of tibia against to femur before and after the sensorimotor training. Results: There was significant relaxation on the affected side in tibia anterior displacement of the affected and sound sides on in supine position before the sensorimotor training. There was little significant difference in tibia anterior displacement of the affected knee joints on in the supine position before and after the sensorimotor training. The results also showed that there was a reduction in the difference of tibia anterior displacement of the affected knee joints on in the standing position. These results suggest that the effects of sensorimotor training on knee joint stability after anterior cruciate ligament reconstruction is to induce the change of tibia anterior displacement against femur and the variation of muscles activation. Conclusion: The sensorimotor training may contribute to the improvement of joint functional stability in people who are in post-operation state and with orthopedic musculoskelectal injuries.

Aggressive revascularization of the ischemic lower extremities in atherosclerotic, occlusive diseases or acute embolic arterial occlusion due to cardiac valvular disease by thromboembolectomy or an arterial bypass operation has been advocated by some authors. We have performed 68 first time vascular operations, including thromboembolectomies on RR patients with ischemic lower extremities, within an 11-year-and-6-month period, from January 1974 to June 1984. We have reviewed and analyzed our vascular operative procedures and post operative results. The patients upon whom thromboembolectomies were performed were 42 males and 13 females ranging from 5 to 72 years of age. The major arterial occlusive sites were common iliac artery in 20 cases, femoral artery in 21 cases, popliteal artery in 8 cases, common iliac artery and femoral artery in 4 cases, and femoral artery and popliteal artery in 3 cases. The underlying causes of arterial occlusive disease were atherosclerosis obliterans in 34 cases; Buerger`s disease in 3 cases; emboli due to cardiac valvular disease in 13 cases; and vascular trauma in 4 cases, including cardiac catheterization in I of those cases. Arterial bypass operations with autogenous or artificial vascular prosthesis were done in 31 cases. Amputations were done on 2 patients carrying out any more vascular operative procedures would have been of no benefit to them. Our bypass operations for ischemic lower extremities were classified as follows: those done between the abdominal aorta and the femoral artery in 17 cases, including those done between the aorta and the bifemoral arteries with a Y graft in four of those cases and long ones done from the axillary to the femoral artery in 4 cases. Five patients died in the hospital following vascular surgery for ischemic lower extremities, the causes of death were not directly related to the vascular reconstructive operative procedures. The leading causes of death were respiratory failure due to metastatic lung carcinoma: renal failure due to complications from atherosclerosis obliterans; sepsis from open, contaminated fractures of the tibia and fibula; and myocardial failures due to open heart surgery in one case and reconstructive surgery of the ascending aorta in another.

Objectives : To determine the impacts of Diagnosis-Related Groups/Prospective Payment System (DRG/PPS) on the quality of care in cases of Cesarean section and to describe the policy implications for the early stabilization of DRG/PPS in Korea. Methods : Data was collected from the medical records of 380 patients who had undergone Cesarean sections in 40 hospitals participating in the DRG/PPS Demonstration Program since 1999. Cesarean sections were peformed in 122 patients of the FFS(Fee-For-Service) group and 258 patients of the DRG/PPS group. Measurements of quality used included essential tests of pre- and post-operation, and the PPI(Physician Performance Index) score. The PPI was developed by two obstetricians. Results : Univariate analysis demonstrated significant differences in PPI scores according to the payment systems. With respect to the mean of PPI scores, a higher score was found in the DRG/PPS group than in the FFS group. However, the adjusted effect did not show significant differences between the FFS group and the DRG/PPS group. Conclusion : This study suggested that the problem of poor quality may not be related to the implementation of DRG/PPS in Cesarean section. However, this study did not consider the validity and reliability of the process measurement, and it did not exclude the possibility of data emission in medical records.

Objective : In general, to perform posterior lumbar interbody fusion(PLIF), it has been used more invasive procedure than simple discectomy. However we try to perform PLIF with TFC with smaller invasion almost same as in simple discectomy. This study is about its procedure and clinical results. Materials and Methods : The authors retrospectively analyzed 43 cases of minimally invasive PLIF with TFC from July 1998 to May 2000. Operative procedure, operative complication, change of disc height, blood loss, ambulation time, hospitalization period, clinical success rate, and bony fusion rate were analyzed. Results : 40 patients were capable to walk on the 2nd day of the post-operation. The average hospitalization period is 5.6 days. The average blood loss was 0.19L/level with no transfusion or wound drainage. The height of disc changed from 8.84mm to 13.54mm. Clinical success rate is 95% when evaluated by the Prolo's scale. The complication was delayed wound infection(2) and transient paresthesis(1). The bony fusion was shown in 17 patients (94.4%) out of 18 patients who passed one year. Conclusion : As a result of minimally invasive PLIF, pain was decreased and early ambulation and short hospitalization was possible. Complication was similar or lower than other studies, and the bony fusion rate and clinical success rate were also similar during follow-up.

Purpose: There have been few case reports regarding treatment plans for long-term, neglected scalp defects and calvarial defects with subdural abscess. The purpose of this case report is to present our experience with a free latissimus dorsi musculocutaneous flap for scalp and calvarial defects and to discuss flap options in comparison with a literature review. Methods: A 60-year-old man who fell down from a four-story-height that resulted in a craniotomy in 1979; he visited our outpatient clinic for a chronic, purulent scalp and calvarial defects with unidentified artificial bone. The artificial bone was removed by a neurosurgeon and reconstructed with a free latissimus dorsi musculocutaneous flap. The deep temporal artery was used as a recipient artery. The postoperative flap status was excellent until the 6th day post-operation when the patient experienced a seizure, and an arterial insufficiency occurred at the flap probably due to an arterial spasm. Emergency exploration with arterial re-anastomosis was performed and the flap status was stabilized. Results: Complete wound healing was achieved after 3 weeks without infectious and systemic postoperative complications. During the 6 month follow-up period, there were no complications. Conclusion: We suggest the latissimus dorsi myocutaneous free flap as a good treatment option for a chronic, purulent, complicated scalp with calvarial defect, as a well as treatment for an acute traumatic defect.
