목적: 무시멘트형 양극성 반 인공 관절 치환술에 있어서 수술 도중 발생하는 대퇴 골절 예방을 위한 예방적 강선 고정술의 효과를 분석하고자 한다. 대상 및 방법: 2004년 1월부터 2008년 8월까지 무시멘트형 양극 인공 관절 치환술을 받은 65세 이상의 환자 48명(1군)을 대상으로 하여 강선을 사용하지 않은 48명의 환자(2군)와 비교하였다. 평균 나이는 75.4세(1), 73.6세(2)이었고 평균 추시 기간은 19.1개월(1), 18.3개월(2)이었다. 수술 도중 골절 발생율 외에 수술 시간, 수술 도중 예상 출혈량, 입원 기간, 방사선학적 안정성을 측정하였고 임상적 평가를 위한 대퇴 통증과 Jensen의 기능 점수와 Parker와 Palmer의 활동 점수를 비교하였다. 결과: 1군에서는 수술 도중 골절이 발생하지 않았으며 2군에서 4예(8.3%)가 발생하였다(p=0.041). 수술 시간은 각각 172분(1), 162분(2) 예상 출혈량은 866 cc(1), 855 cc(2), 입원기간 36일(1), 35일(2)이었다. 방사선학적으로 침강은 1.59 mm(1), 1.67 mm(2)이었으며 임상적으로 대퇴 통증이 1예(1), 2예(2) 관찰되었다. 임상적으로 Jensen의 기능 점수는 평균 2점(1) 2.2점(2), Parke와 Palmer의 활동 점수는 평균 5.2점(1), 5.3점 (2)이었다. 결론: 무시멘트형 인공 관절 치환술에 있어서 예방적 강선 고정술은 골절률을 의의있게 감소시켰다. Purpose: The purpose of this study was to assess the effect of a prophylactic cable fixation for prevention of femoral fractures in cementless bipolar hemiarthoplasties. Materials and Methods: Forty-eight cementless bipolar hemiarthroplasties with prophylactic cable fixations on the femur were performed in patients>65 years of age between January 2004 and August 2008 (group 1). The control group which did not undergo prophylactic cable fixation included 48 cases (group 2). The mean age was 75.4 years (group 1) and 73.6 years (group 2). The patients were followed up for an average of 19.1 (group 1) and 18.3 months (group 2). The intra-operative fracture rates were compared. Additionally, operative time, estimated blood loss (EBL), and length of hospital stay were compared. Radiologic assessment for stem stability was performed. Clinical assessment was evaluated by the thigh pain and Jensen`s functional score, and Parker & Palmer`s mobility score. Results: There was no fractures in the cabled group (1), and 4 fractures (8.3%) in the control group (2; p=0.041). The mean operative time was 172 minutes (1) and 162 minutes (2), the EBL was 866 cc (1) and 855 cc (2), and the duration of admission was 36 (1) and 35 days (2), respectively. Radiologically, subsidence was 1.59 mm (1) and 1.67 mm (2). Clinically, one (1) and two (2) thigh pains were recorded and the functional score of Jensen was 2 (1) and 2.2 points (2), and the mobility score of Parker and Palmer was 5.2 (1) and 5.3 points (2), respectively. Conclusion: Prophylactic cable fixation is effective for reducing intra-operative femoral fractures.

Radiofrequency ablation(RFA), as a form of minimally invasive therapy for hepatocellular carcinoma, has become an important treatment modality. Because of limitation of surgery, RFA has become standard therapy for hepatocellular carcinoma in some situations. But there are some complications of RFA such as bleeding, infection, hematoma, adjacent organ thermal damage including intestinal perforation, needle track seeding, and so on. There are few reports in the literature that systematically evaluate the incidence of needle tract seeding and its associated risk factors. And only 2 cases of needle tract seeding of hepatocellular carcinoma after RFA were reported in Korea. We report a case of needle tract seeding of hepatocellular carcinoma after RFA.

Malignant tumor of the head and neck can be treated by radical excision of the lesion. But the resultant facial deformity acts as a handicap in the patient's life. The quality of life is as important as the quantity. Therefore reconstruction of these patients is an important field in plastic surgery. We used 3 kinds of flap for reconstruction after maxillectomy. Two cases were late reconstruction with Rectus Abdominis myocutaneous free flap and parascapular free flap respectively. In remaining one case, immediate reconstruction was performed with rib bone graft and Latissimus Dorsi free flap. The results were satisfactory. But we found that ptosis of the flap is problem in all cases.

Background : Since 1997, the annual case occurrence of vivax malaria in the Republic of Korea have exceeded 1,000 cases since 1997. The military is thought to be an important source of the current outbreak. We collected various informations about malaria cases (soldiers, veterans and civilians) which occurred in 2000, and analyzed the characteristics of the current outbreak. Methods : Informations about malaria cases of soldiers, veterans and civilians, including name, age, sex, day of onset, region, etc., were collected through the National Institute of Health. Results : Out of total 4,141 cases, 1,288 (31.1%) occurred in the military, 1,273 (30.7%) occurred among the veterans, and 1,580 (38.2%) occurred among civilians. The monthly case occurrence reached its peak in early August. Areas such as Cheolwon, Yeoncheon and Paju showed the highest prevalence. Conclusion : It is considered that the current malaria outbreak has escaped from the exponential growth phase, however, more attention should be paid to prevent further spreading of malaria infection.

The programmer in the distributed environment is often faced with problems when writes a communication code. One is written the codes by hand and the other is by CORBA IDL compiler. When the programmer writes the code by hand then the speed of the program may be increased, but the human effort required to implement and maintain is greatly increased. If the code is generated using a CORBA IDL compiler then programmer effort will be reduced, but the performance of the Application program may be poor. In this paper, we suggests the way that the stub code is maintain the enough free space before marshaling the data into message buffer. This methods were increased the performance of Application program and solved the problems that optimizing of code.

연구배경: 당뇨병성 신경병증은 당뇨병 환자에서 흔히 나타나는 합병증으로서 임상 증상은 가볍거나 없을 수도 있지만 많은 경우에 통증, 작열감, 이감각증이나 무감각증 등의 증상을 동반하지만, 이에 대한 명확한 기전이나 뚜렷한 치료방법이 없었다. 최근에 신경세포내 산화성 스트레스의 증가로 신경세포의 손상이 발생된다는 기전이 주목을 받으면서, 당뇨병성 신경병증 환자에게 항산화제인 thiotic acid를 사용하여 좋은 효과를 관찰한 논문들이 발표되었다. 이에 저자들은 한국의 당뇨병성 다발성 신경병증 환자에서 thiotic acid를 경구 투여 후에 신경병증에 의한 효과 및 안정성을 평가하였다. 방법: 모든 대상 환자에게 Thioctic acid 600㎎ 을 1일 1회 아침 식전 30분에 8주간 투여하여 당뇨병성 다발성 신경병증에 대한 TSS의 개선여부에 대한 임상적 유효성 및 이상반응, 내약성, 실험실적 지표의 변화를 통한 안정성을 관찰하였다. 결과: 치료시작 전에 관찰한 환자가 호소하는 증상은 통증이 가장 많았으며 무감각, 작열감, 이상감각 순의 빈도를 보였다. 통증, 작열감, 이감각증, 무감각증의 평균 TSS는 1차 방문시 5.8± 1.8, 2차방문시는 4.4±1.7, 3차 방문시는 3.1±1.1로 사용기판에 따라 통계학적으로 유의한 증상의 호전이 있었다. 또한 TSS의 개선 뿐만 아니라 통증, 작열감, 이감각증 및 무감각증 각각의 증상도 치료전과 치료 4주 후 및 치료 8주 후를 비교했을 때 통계학적으로 유의한 증상의 호전이 있었다. TSS가 1차 방문 시와 비교했을 때 3차 방문시에 30% 이상 개선되었을 때(1차 방문시에 TSS 4인 환자는 2점 이상 개선되었을때) 임상적으로 의미가 있는 반응으로 간주하고 계산한 반응률은 71.3%였다. 결론: 당뇨병성 다발성 신경병중 환자에 대해 항 산화제인 thioctic acid 600㎎ 경구 투여요법은 당뇨병성 신경병증의 증상완화에 유용하며, 안전한 것으로 사료된다. Background: The study was peformed to evaluate the efficacy and safety of oral treatment with the antioxidant α-lipoic acid (Thioctcid??) in diabetic patients with peripheral polyneuropathy. Methods: Thioctacid?? 600㎎ was orally administered once a day for 8 weeks in 61 diabetic patients with peripheral polyneuropathy. Neuropathic symptom(pain, burning, paresthesia, and numbness) were scored before, and of 4 and 8 weeks after treatment. In addition, neuropathy by the physician and patients at the end of treatment. The primary endpoint was the response role after 8 weeks treatment, defined as an improvement in the total symptom score of at least more than 30%. Results: Efficacy was evaluated among forty-four patients who had completely the study according to the protocol and safety was evaluated among all of 61 patients who had taken the study medication. The response rate after 8 weeks was 77.3%. The total symptom score was significantly decreased of 4-week, and further decreased of 8-week. All the individual scores for neuropathic symptom were also significantly reduced of 4-week and further decreased at 8-week. Conclusion: These finding indicate that oral treatment with thioctacid?? at a dose of 600㎎/day for 8 weeks will improve peripheral polyneuropathy in diabetic patients, without causing any serious adverse events.

The Taguchi method by orthogonal array, one of the structured sampling methods, has many advantages which are row cost and time saving for experiments and researches. But this method has applied limited area especially about mechanical problems. So, we experimented whether the structured sampling is useful to apply optimal design of mechanical elements. First, we made a mechanical problem to determine optimal parameters of a pin with a hole. The second, we calculated combination of optimal parameters by simulation. At the same time, we seeked optimal combination by structured sampling using orthogonal array and ANOVA(Analysis of Variance). The last, we compared these two results. The experimental result have shown that the structured sampling method seeked optimal parameters exactly. So, we see some possibility in this application.

Urine certified reference material(CRM) has been developed to help clinical labolatories control analytical accuracy. Two levels of freeze-dried urine were prepared. The low level CRM was made from normal urine and the abnormal level CRM was prepared by spiking th normal urine with As, Cd, Cr, Cu, Hg, Ni and Pb. Urine reference materials were analyzed by graphite furnace atomic absorption spectrometry(GFAAS) and inductively coupled plasma mass spectrometry(ICP-MS). Analyte elements were separated from matrix elements by using ion exchange resin and hydride generation. Isotope dilution method was employed to enhance analytical accuracy. Round robin test results are also presented which were carried out with 5 clinical laboratories.

The purpose of this study was the effects on the movement accuracy of distance and direction with the changes of visual feedbacks and arm actions. The six ballet-majored subjects were classified into High group and Low group by their dance career. All data were expressed as mean, standard errors and t-values, and the .05 level was initially established in significance. The conclusions were summarized as follows; 1. Movement time was not significant in all conditions, but very similar significant level in condition 1 between High group and Low group(P<.05). 2. Movement distance was only significant in condition 2(P<.05), but not significant in the other conditions between High group and Low group. In fact, the movement distances of High group were more longer than Low group in all conditions. 3. Distance error was significant in condition 2 and 3(P<.05), and very significant in condition 4, but not significant in condition 1 between High group and Low group. Distance errors in High group were positive(+) errors, but negative(-) errors in Low group in all conditions. 4. Direction error was significant in condition 3(P<.05), and not significant in the other conditions, but very similar significant level in condition 2 and 4(P<.05) between High group and Low group. The general tendency of direction errors was appeared to negative directive(-) in condition 1 and 3(vision condition), but positive direction(+) in condition 2 and 4(Non-vision conditions) in both group. 5. It was concluded that the significant factor determining the movement accuracy of distance and direction in Ballet Chaine was not their arm action but their visual feedback condition. And the visual feedback condition was not effected on movement time of Chaine.
