Purpose: To compare the results of arthroscopic rotator cuff repair and subacromial decompression in partial thickness rotator cuff tear (PTRCT) with those in full thickness rotator cuff tear (FTRCT). Subjects and method: Of the 46 patients who were rested of the rotator cuff tear based on the operational findings, 42 patients who were able to receive a serial follow-up for 2 years were selected as the study subjects. The average age of the patients at the time of the operation was 55 years, and the mean duration of the follow-up was 34 months. The subjects included 22 cases of PTRCT and 20 cases of FTRCT. In terms of rotator cuff repair, the average number of tendon to tendon repair (TTR) was 1 in both PTRCT and FTRCT, and that of tendon to bone repair (TBR) was 1 and 3 in PTRCT and FTRCT, respectively. The average number of use of suture anchor was 1 and 2 in PTRCT and FTRCT, respectively. The level of shoulder pain and function of the subjects were measured using shoulder functional evaluation score of American shoulder and elbow society (ASES score) at before and 2 years following the operation. Results: At the final follow-up following the operation, PTRCT group showed changes in scores from 7.2 to 0.9 on average pain score and 34 to 91 on ASES score, whereas FTRCT group showed changes in scores from 7.6 to 1.2 on pain score and 29 to 88 on ASES score. There were no significant differences between the two groups (P > 0.05). The average range of motion of shoulder significantly increased in both groups at the final follow-up in comparison with the pre-operative time point. The evaluation at the final follow-up showed that 93% of the total subjects showed good or excellent results, and 95％ showed satisfactory results from the procedure with regard to pain reduction and functional outcomes. Two cases of the 3 fair results were caused by acromioclavicular arthritis. Conclusion: It may be anticipated that arthroscopic rotator cuff repair and subacromial decompression may bring satisfactory post-operative outcomes in both PTRCT and FTRCT on pain relief and functional recovery. However, careful preoperative examination of the acromioclavicular joint is critical to avoid failures of these procedures.

최근 ITU-T/VCEG과 ISO/IEC MPEG은 공동으로 차세대 비디오 압축 표준 기술인 High efficient video coding (HEVC)를 제정하고 있다. HEVC는 H.264/AVC 표준 기술과 비교해 보면 매우 향상된 압축 효율을 보여 주고 있으며, 특히 Full HD 이상의 매우 큰 사이즈의 동영상 및 그에 따른 고화질 비디오 서비스를 주요 목표로 하고 있다. 그러나 품질과 압축 효율 향상을 위해 새로운 구조와 압축 도구들이 추가됨으로써 인코더의 연산 복잡도가 매우 증가되어 있으며, 이에 화질의 열화를 최소한으로 유지하면서 계산량을 감소시키는 연구가 필요해 지고 있는 상황이다. 본 연구에서는 화면 간 예측 시에 부호화 단위의 분할을 효율적으로 조기 종료하는 방법을 제안한다. 제안된 방법은 현재 코딩 단위 (Coding unit)의 움직임 벡터 정보, 율-왜곡 비용, 그리고 상위 코딩 단위에서의 개별 사이즈에 대한 평균 율-왜곡 비용값을 활용하여 분할을 조기에 중단한다. 실험 결과를 통하여 제안된 방법이 기존의 ECU 방법보다 약 10% 정도로 속도 향상이 있으며, HM 참조 소프트웨어와 비교 시 BD-rate 증가는 1.975% 정도로 매우 적게 나타남을 보인다.

Objectives : This study was designed to assess the general distribution, clinical effectiveness of Korean medical treatment on knee pain and the correlation between Korean medical therapy on knee pain and BMI. Methods : This is an observational study. 65 patients admitted to Daejeon Jaseng Hospital of Korean Medicine with musculoskeletal disorders were observed from July, 2014 to July, 2015. They were analyzed according to sex, age, pain lesion, body mass index(BMI) and treatment efficacy. All patients received a combination of treatments during hospitalization, including acupuncture, pharmacopuncture, herbal medicines and physical therapy. A zero to ten numerating rating scale (NRS) assessing pain, Western Ontario and McMaster Universities Arthritis Index(WOMAC) index and Range of Motion(ROM) was used before and after treatments. Statistical correlations among assessment measurements were evaluated by examining the paired t-test and the Pearson's correlation coefficients. Results : The average BMI of all patients was $24.03{\pm}2.95kg/m^2$. According to clinical definition of obesity by Korean Society for the Study of Obesity, 33.8% of all patients was within normal weight, 1.5% was underweight, 33.8% was overweight, 24.6% was obesity and 6.2% was morbid obesity. For knee pain patients, NRS (Numeric Rating Scale) decreased from $6.28{\pm}1.63$ to $3.94{\pm}2.03$(p<0.001). WOMAC index decreased from $48.14{\pm}17.63$ to $40.37{\pm}18.28$(p<0.001). But, there were no significant correlations in statistics among BMI, knee pain index and knee pain index improvement. Conclusions : Korean medical combination treatment might be effective in reducing pain and improving functional disorders for patients with knee pain. This study further confirmed the efficacy of Korean medical treatment on knee pain. But, more studies on correlation between knee pain and obesity and development of assessment measurement are needed.

Purpose: To analyze the clinical and radiologic results of the shoulder arthrodesis in brachial plexus injury patients with flail upper extremity. Material and Method: From Aug 1978 to April 2008, 29 shoulders in 29 patients with brachial plexus injury with shoulder fusion, we evaluated 20 shoulders in 20 patients, more than 1 year follow up. The average follow-up period was 6.45years (range: 1year~24years). There were 13 men and 7 women, and the mean age at the time of trauma was 32.0years(2~65 years). The type of injury was a motorcycle accident in 11 patients, in car accident in 5, pedestrian accident in 3, and fall from a height in 1. The lesion of injury was root and trunk in 1 patient, trunk and cord in 1, trunk in 18. Surgery was performed on the whole arm type paralysis in 12 patients, lower arm type paralysis in 8 patients. The preoperative visual analog scale score was 8.7(7~10). When the trapezius and serratus anterior muscle were in function, operation was performed. 18 patients were processed to the additional operation. Gracilis free flap in 6 patients, neurotization in 3, Steindler flexor plasty in 6, and tendon transfer in 3 were performed. Fixation was conducted with cancellous screws in 13 patients, Knoles pins in 5, and cancellous screws and Knoles pins in 2. The position of the arthrodesis at operation was $28.5^{\circ}$($20~45^{\circ}$) in abduction, $30.3^{\circ}$($20~45^{\circ}$) in flexion, and $30.8^{\circ}$($20~40^{\circ}$) in internal rotation. Result: The follow up visual analog scale score was 3.4(0~7). Postoperatively, shoulder spica cast was applied for 15.3weeks(8-20weeks). The median time to bony union was 17.7weeks(9~28weeks). Average range of motion was $32.0^{\circ}$($15~40^{\circ}$) of abduction, $24.0^{\circ}$($10~40^{\circ}$) of flexion, and $18.5^{\circ}$($10~30^{\circ}$)of internal rotation. Conclusion: The shoulder fusion in brachial plexus injury patients is one of the good methods to relieve pain, improve the function and stabilize the flail shoulder joint.
