Between June 1989 and may 2004 Ipsilateral vascularized fibular transposition was performed on nine patients with segmental tibial defects combined with infection following trauma. Ipsilateral vascularized fibular graft was performed on two or three stage according to the degree of infection. Initially free vascular pedicled graft was done followed by ipsilateral vascularized fibular graft. Type of free flap used is scapular free flap 3 cases, latissimus dorsi free flap 5 cases and dorsalis pedis flap 1 cases. The patients were followed for an average of 3.4 years. the average time to union was 6.7 months, and in all patients the graft healed in spite of complication. Complication was free flap venous thrombosis in 1 cases, persistent infection in 1 cases, delayed bony union at the distal end of fibular graft in 2 cases. The results showed that more faster bony union was seen in which cases firmly internally fixated and more faster hypertrophy of graft in which cases was permitted to ambulate on early weight bearing and more faster healing in which cases debrided more meticulously. Reconstruction of tibia defect with free flap followed by Ipsilateral fibular transposition is a useful and safe method to avoid the potential risk of infection for patients with tibial large bone defect and soft tissue defect associated with infection.

본 연구는 미국 Utah주의 Logan시에 있는 유타주립대하(USU)Credit Union의 멤버들을 대상으로, 신용사용과 신용에 대한 태도가 그들의 경제적 만족도와 어느정도 관련이 있는지를 조사하였다. 연구는 1989년 3월에서 5월까지 걸쳐 USU Credit Union의 지원으로 이루어졌으며, 자료는 21세에서 65세까지의 멤버들 중 500명을 임의 추출하여 설문지 조사를 실시하여(설문지는 본 연구를 위한 문항과 Credit Union 멤버 Survey문항이 함께 이루어졌다) 그중 274명(54.8%)으 답변이 자료분석에 사용되었다. 대부분의 사람들은 집이나 차, 또는 교육비, 의료비에 신용을 사용하는데 긍정적 태도를 보였으며, 반수 이상의 사람들이 신용을 사용함으로써 수수료 또는 이자를 지불하고 있었다. 월평균 신용 납부액은 $643이였으며, 반수 이상의 응답자가 그들의 신용차입액에 대해 걱정하고 있는 반면, 4.4%의 응답자만이 신용을 사용하지 않고 있다고 대답했다. t-테스트, 변량분석, 그리고 상관관계 분석에 의해 경제적 만족도와 의미있는 관계를 가지고 있는 요인들이 단계별 다중 희귀분석에 이용되었는데, 그 결과 사람들의 신용부담액에 대한 근심도가 그 어느것보다도 경제적 만족도와 강하게 연관되어 있는 것으로 나타났다. 이는 과거의 조사들이 가정의 빚, 즉 신용부담액과 수입에 대한 비율로써 가정의 경제적 만족정도(financial well-being)를 측정해온 것에 반한 사실로서, 경제적 만족도는 개인의 주관적 측정인 신용부담액에 대한 근심도와 큰 관련이 있음을 보여주었다.

Congenital dilatation of the common bile duct (choledochal cyst) is an uncommon disease. Although the etiology is unknown yet, various theories such as distal obstruction of the common bile duct, congenital weakness of the duct and anomalous union of the pancreaticobiliary duct have been offered to explain the occurrence of choledochal cyst. Thirty - six cases of choledochal cyst over 22 years were analyzed clinically and classified according to Todani's classification and Kimura's anomalous union of pancreaticobiliary duct type. Todani type 1 consisted with 22 cases which were subdivided into 19 cases of type Ia, 1 case of type Ib and 2 of type Ic. Type IVa consisted with 14 cases including one case of Caroli's disease. There were 25 type BP cases and 10 type PB cases and 1 normal pancreatobiliary junction. Serum alkaline phosphatase was increased significantly in almost all cases. Seven patients (19.4%) had associated congenital anomalies such as double gallbladder, left - sided gallbladder, common bile duct web, biliary atresia, accessory hepatic duct, heterotopic pancreas, cleft lip and 2 cases of intestinal malrotation. All patients underwent cyst excision and Roux - en - Y hepaticojejunostomy and cholecystectomy. There was one death due to methicillin resistant Staphylococcus aureus sepsis.

Chronic pancreatitis is a progressive inflammatory disease resulting from repeated episodes of acute pancreatitis that impair exocrine function and eventually produce endocrine insufficiency. Some causes of chronic pancreatitis appear to be associated with alterations in the serine-protease inhibitor, Kazal type 1 (SPINK1), cationic trypsinogen (PRSS1), and cystic fibrosis-transmembrane conductance regulator (CFTR ) genes, or with structural disorders in the pancreaticobiliary ductal system, such as pancreatic divisum or anomalous pancreaticobiliary ductal union (APBDU). However, it is unusual to observe both genetic alteration and structural anomaly. Here, we report 2 cases with both APBDU and a mutation in the SPINK1 genes, and we discuss the implications of these findings in clinical practice.

Let R be a commutative ring with identity, X the set of all nonzero, nonunits of R and G the group of all units of R. We will investigate some ring theoretic properties of R by considering $\Gamma$(R), the zero-divisor graph of R, under the regular action on X by G as follows: (1) If R is a ring such that X is a union of a finite number of orbits under the regular action on X by G, then there is a vertex of $\Gamma$(R) which is adjacent to every other vertex in $\Gamma$(R) if and only if R is a local ring or $R\;{\simeq}\;\mathbb{Z}_2\;{\times}\;F$ where F is a field; (2) If R is a local ring such that X is a union of n distinct orbits under the regular action of G on X, then all ideals of R consist of {{0}, J, $J^2$, $\ldots$, $J^n$, R} where J is the Jacobson radical of R; (3) If R is a ring such that X is a union of a finite number of orbits under the regular action on X by G, then the number of all ideals is finite and is greater than equal to the number of orbits.

Purpose: To evaluate the results of ankle lateral malleolar fractures classified as Danis-Weber type B accompanying osteoporosis that were treated with lag screw. Materials and Methods: 15 cases of Danis-Weber type B ankle lateral malleolar fractures that had T score of less than -2.5 in BMD(bone mineral density) test were selected from June 2003 to December 2005. 10 cases were males and 5 cases were females with mean age of 59 years. The main injury mechanism was supination and external rotation. Mean follow-up period was 16 months. Clinical and radiologic evaluation was done according to Meyer and Kumler's criteria. Results: All cases showed satisfying result and mean radiologic bone union period was 3 months. Anatomic reduction and bone union was acquired in all cases without complications including wound infection, skin necrosis, delayed union and nonunion Conclusions: Lag screw fixation seem to be excellent treatment of Danis-Weber type B lateral malleolar fractures with osteoporosis as it can minimize soft tissue injury and enable anatomic reduction with firm fixation.

Purpose : To evaluate functional results and study factors influencing results after humeral hemiarthroplasty for comminuted fractures of the proximal humerus. Materials and Methods: We reviewed 12 patients with average follow-up period of 23 months(12 to 42). The proximal humeral fractures consisted of one anatomical neck fracture, five three-part and six four-part fractures or fracture-dislocations. Constant score and Compito et al' evaluation system were used for clinical assessment. Statistical analysis was done with the Wilcoxon test. Results: Six cases of anatomical neck, three-part fractures or fracture-dislocations showed 61 points on the average Constant score and three unsatisfactory results on the Compito et al' evaluation; Six of four-part fractures or fracture-dislocations showed 51 points and three unsatisfactory results. There were 59(two unsatisfactory) for five non-associated dislocation and 53(four unsatistactory) for seven associated dislocation; 66(one unsatisfactory) for three under 60 years and 41(five unsatisfactory) for nine over 60 years; 67(two unsatisfactory) for seven tuberosity union and 41(four unsatisfactory) for five tuberosity non-union or resorption; 58(four unsatisfactory) for ten early operation within two weeks and 43(all unsatisfactory) for two delayed operation; and 18(unsatisfactory) for one case of a accompanied rotator cuff tear. Conclusion: We concluded that tuberosity union was important factor influencing the results. Also, we thought that age, timing of operation and accompanied rotator cuff tear could be influenced to results.

Today's Internet environment is growing rapidly, and transactions based on it are also rapidly increasing. E-commerce allows merchants and consumers in different countries to easily trade goods across borders. However, the increase in international consumer transactions through the Internet is accompanied by an increase in disputes. International consumer transactions are characterized by a distinction among long distance, small sum, and different jurisdictions. International consumer transactions cannot be solved only by way of resolving disputes in past international transactions. The best way to resolve disputes between international carriers and consumers is through the Internet. In this regard, UNCITRAL has been preparing to enact legislation on ODR as a solution to international electronic trade disputes and, as a result, UNCITRAL adopted guidelines for operating the ODR procedure for building the ODR platform. The European Union has also increased its disputes in the European Union, which is active in the intra-regional market. Institutional improvements were made to solve this problem; therefore, the European Union (EU) has enacted the ODR Regulations for EU consumer disputes. Based on such, this study constructed the ODR platform, which is used as a way to resolve consumer disputes in the regional market.

본 연구에서는 초소형 화의 욕구와 고밀도의 내실을 동시에 충족시킬 수 있으며 전자 장해를 발생하지 않는 일체형 인덕터 코어를 개발하기 위한 방법의 하나로 고전류인가에 따른 인덕터의 전자장 특성을 분석하고자하였다. 분석 결과, 인덕터 내부에서는 전자장이 크게 발생하였지만 인덕터 표면에 나타나는 자장분포 값은 매우 미약하여 주위의 다른 전자 부품에 영향을 미칠 정도는 아니었으며, 표면을 벗어나면 그 값은 순식간에 거의 0[T]로 작아지고 있기 때문에 일체형 인덕터를 이용하여 회로를 구성하였을 때 다른 전자 부품들에 대한 전자 장해는 발생하지 않을 것으로 생각된다. 이 결론은 일체형 인덕터 개발에 많은 영향을 미칠 것이며, 특히 인덕터 코어의 특성 분석 및 신뢰도 향상에 많은 도움이 될 것으로 예상된다.
