Purpose: To present our experience and design modification of an anterolateral thigh flap in soft tissue reconstruction. Materials and Methods: Between April of 2004 and May of 2005, 26 anterolateral thigh flaps were used in 26 patients. There were 22 males and 4 females between 23 and 60 years (mean, 40years). The mean follow-up period was 11($4{\sim}18$) months. All cases were a cutaneous flap. Twenty-two were musculocutaneous perforator flaps(85%) and 4 were septocutaneous perforator flaps(15%). Four flaps were used as a sensate flap. While the donor sites were closed directly in 14 cases(54%), 12 cases(46%) underwent skin grafting of the donor site. During the flap design, a triangular skin design was added to a vascular anastomosis site in 14(54%) patients and used as a roof of the tunnel. The healing period of the skin graft between those performed above the fascia and above the muscle were compared. Results: The average size of the flaps was $16{\times}9(11-20{\times}7-12)\;cm$. The overall flap success rate was 96%. Complications encountered were infection in 4 cases, and marginal skin necrosis in 1 case. The healing period was delayed with the infection in 3 of the 6 cases involving a skin graft over the fascia. All 14 cases with the triangular skin design survived, but there was 1 flap failure and 1 marginal necrosis in 12 cases without a triangular skin design. Conclusions: It may be better to undergo a skin graft above the muscle than above the fascia in covering a donor site defect, and to use a triangular skin design in order to prevent vascular insufficiency. An anterolateral thigh flap is a versatile flap for a soft tissue reconstruction because its thickness and volume can be adjusted to the extent of the defect with minimal donor site morbidity.
ECU HILS를 이용한 실차 주행 조건에서의 인젝터 평가시스템

A fuel injection system using an ECU HILS as an alternate to a vehicle test for the fuel injectors was developed. The throttle position, vehicle speed, engine speed, crank position, cam position, intake air flow, and several other sensor signals that are supplied to the ECU were measured and recorded as a data file for a vehicle driven in the FTP-75 mode in a chassis dynamometer. Electric signals that are equivalent to the sensor signals from the vehicle are reconstructed from the recorded data file using data acquisition boards, microprocessors, and computers. All sensor signals are supplied to the ECU with synchronized timing using a computer program. The findings show that the cost and time of vehicle experiments can be reduced using the ECU HILS system. Moreover, the repeatability of the generation of sensor signals can enhance the accuracy of a range of experiment related to vehicle testing. An ECU scanner that scans the sensor signals that are input to the ECU through a serial port was used to assess the accuracy of the reconstructed signals. The scanning results show good agreement with the reconstructed input signals. Injectors were connected to the ECU HILS system and were driven by the system to measure the quantity of injected fuel.

Mixing process of impinging jets of liquid oxidizer and liquid fuel is simulated by using water and sodium carbonate (Na$_{2}$CO$_{3}$) solution. The shapes of liquid sheets are visualized and flowrate distributions are measured by collecting droplets using measuring cells. Mixing charateristics are studied by using acid-base titration. Stable liquid sheets are formed and two liquid jets are well mixed for symmetric impinging jets. Similarity in flowrate distribution for various measuring heights is observed. For asymmetric impinging jets, liquid sheets become unstable as the difference in the velocities of jets increases. In some extreme cases, liquid sheets are not formed and the jets are separated. Dimensionless variables are adopted demonstrating similarly in flowrate distribution. Mixing characteristics vary significantly with experiment conditions.

The purpose of this study was to investigate the difference on ground reaction forces during pitching between the experienced group and the unexperienced group. The subject were divided into two groups consisting 5 mails respectively. The dependence variable was pitching experience and the independent variables were total contact time, vertical ground reaction force, anterior-posterior ground reaction force, inner-outer ground reaction force, maximal vertical ground reaction force. For statistical analysis, independent- samples test was used. On the basic of the results in this study, conclusions were as follows : 1. The experienced group had shorter total contact time than the unexperienced group(p< .05). 2. There was no significant difference between the two groups for the maximal vertical ground reaction force(p,< .05) 3. There was no significant difference between the experienced group and the unexperienced group for the Anterior-Posterior ground reaction force , except for the crossing of braking force and propulsive force (p< .05). 4. For the inner-outer ground reaction force, The experienced had greater outer force than the unexperienced group(p< .05).
중국에서의 소프트웨어 저작권보호(著作權保護)에 관한 연구 -중국의 소프트웨어보호조례를 중심으로-
이충훈 ( Choong Hoon Lee ) 법조협회 2005 法曹 Vol.54 No.8
중국은 2002년 WTO 가입을 계기로 기존의 소프트웨어보호조례를 개정하여 표면적으로는 소프트웨어저작권을 보호하는 세계적인 추세에 보조를 맞추고 있는 듯 보이지만, 아직도 중국의 소프트웨어불법복제는 정상적인 경제사고를 초월하는 정도로 심각한 수준이다. 물론 현행 중국의 소프트웨어보호조례는 다른 나라의 저작권법의 내용과 거의 유사하다고 할 수 있지만 저작권보호방법의 실효성에 대한 비판은 아직도 존재하고 있다. 특히 민사책임과 형사책임 외에 행정적 제재라는 다른 입법례에서 찾아 볼 수 없는 독특한 방법을 두고 있지만, 민사책임의 발생요건이 다른 나라의 저작권법과 비교해 볼 때 엄격하다는 점, 행정적 제재가 가해지기 위한 요건에 사회 공공의 이익을 해한 경우라는 요건이 추가되어 있다는 점, 형사책임이 인정되기 위한 요건으로 영리목적으로 위법소득의 규모가 비교적 크거나 기타 정상이 무거운 경우라는 요건을 추가하고 있다는 점 등에서 아직도 미흡하다고 할 수 있을 것이다.
