The treatment of acute shoulder instability is different from chronic or recurrent instability. The acute shoulder instability usually accompanies bone defect of glenoid cavity and shows severe instability of double disruption of superior shoulder suspensory complex such as coracoid, acromion, clavicle and complex ligament injuries. We report 3 patients who underwent operations for double disruption of superior shoulder suspensory complex and regained shoulder stability.

Purpose: We examined the incidence of root tear of the medial meniscus posterior horn among patients who had undergone total knee replacement and we analyzed the factors that cause this tear. Materials and Methods: We enrolled 258 knees of 173 patients who had undergone total knee replacement from January 2008 to June 2009. The mean age was 68.8 (range: 50∼87). There were 23 men (28 cases) and 150 women (230 cases). We performed statistical correlation analysis between the assumed causes of meniscal tears (age, gender, grade of osteoarthritis, the predisposition site, BMI and varus deformity) and root tears. Results: Meniscal tears were observed in 182 cases (70.5%), and there were 18 cases (64.2%) of 28 cases and 164 cases (71.3%) of 230 cases in the men and women, respectively. Root tear had correlation with the severity of osteoarthritis (p=0.040) and varus deformity (p=0.030), but other underlying factors didn`t show significant correlation (p>0.05). Conclusion: Root tears of the medial meniscus posterior horn in total knee arthroplasty were related to the severity of osteoarthritis and varus deformity, but active interventions are required whether or not there are predisposing factors that cause osteoarthritis.

한국에서도 다양한 종류의 말라리아 보고가 많았지만, 1962년 이후 사일열 말라리아의 보고는 이제까지 없었다. 사일열 말라리아는 사하라이남 아프리카에서 가장 많지만, 다른 말라리아에 비해서는 흔하지 않고, 경한 임상과정과 낮은 치명률을 보이며 치료도 대부분 클로로퀸에 감수성이 있다. 저자들은 특이한 과거력이 없던 건강한 성인이 나이지리아 여행 후 사일열 말라리아에 걸려 내원하여 말초혈액도말검사와 중합효소연쇄반응 검사에 의해 진단하고, atovaquone-proguanil으로 치료된 증례를 경험하고 국내에서 처음으로 보고하는 바이다. There have been several reports of malaria in Korea; however, there have been no reports of Plasmodium malariae infection since 1962. P. malariae infection is most common in sub-Saharan Africa and is described as an infrequent infection with a relatively mild clinical course, low mortality, and high sensitivity to chloroquine. Here we report a case of P. malariae infection, in a previously healthy man, that was imported from Nigeria to Korea. The patient was diagnosed using a malaria smear and nested polymerase chain reaction, and was first treated with atovaquone/proguanil in Korea. (Korean J Med 77:S1323-S1327, 2009)

Systemic lupus erythematosus (SLE) is a chronic inflammatory autoimmune disease that involves many different organ systems, and this illness exhibits a wide spectrum of clinical manifestations. The renal involvement in SLE is called lupus nephritis and 50~80% of patients with SLE suffer from lupus nephritis. Although pericarditis or pericardial effusion is a common cardiac manifestation of SLE, cardiac tamponade is rare. Cardiac tamponade may be fatal if it is not recognized quickly and treated promptly. We report a case of cardiac tamponade associated with lupus nephritis. Treatment consisted of pericardiocentesis and high-dose corticosteroid. (Korean J Med 78:635-639, 2010)

무지외반증 환자에서 제1중족골두의 연골 미란: 수술 중 실측한 연골 미란과 수술 전 측정지표의 연관성

Purpose: To analyze relation between age or parameters measured before operation and cartilage erosion of the first metatarsal head measured during operation. Materials and Methods: The study was targeted at 56 patients and 79 feet, who underwent Scarf osteotomy or Scarf and Akin osteotomy from November 2009 through November 2010, and whose cartilage lesion of the first metatarsal head referred to the cartilage grade III or IV of the International Cartilage Repair Society. The measurement parameters were age, hallux valgus angle, intermetatarsal angle (1~2), tibial sesamoid position, proximal articular set angle and distal articular set angle. The cartilage erosion of the first metatarsal head was measured by one surgeon using cellophane. Occupancy rate and frequent involved sites of the cartilage erosion were recorded using Auto$CAD^{(R)}$ and adobe Illustrator CS4 program. SPSS correlation test and T-test were used for statistical analysis of the parameters and the cartilage erosion. Results: The cartilage erosion was incurred frequently in the sagittal groove and the site where subluxation or dislocation of the tibial sesamoild bone occurred but frequent involved sites had no statistical significance with cartilage erosion. The age showed a statistical significance with the cartilage erosion in the correlation test (p=0.003). Especially, the group of over 51 year old patients was turned out to have association with the cartilage erosion, compared to the group of below 51 (p=0.007). But, hallux valgus angle, intermetatarsal angle (1~2), tibial sesamoid position, proximal articular set angle and distal articular set angle were no statistical significance with the cartilage erosion. Conclusion: We found the more the age of patients increased (especially above 51), the more cartilage erosion increased. And it is thought that we pay attention to reduce tibial sesamoid bone.

군사적, 학술적 목적으로 개발된 인터넷은 기술이 발전함에 따라 상업적 용도로 점점 더 개발되어 현재 가장 중요한 광고 매체 중 하나로 주목 받고 있다. 인터넷을 이용한 광고의 주류라고 볼 수 있는 것이 바로 배너 광고인데 현재 배너광고를 효율적으로 집행할 수 있는 많은 방법들의 연구되고 있지만 인터넷의 가장 주요한 특질인 Interactivity가 부족한 것이 사실이다. 본 프로젝트에서는 인터넷 배너광고의 Interactivity를 극대화시키기 위한 연구를 진행하고 Interactive Banner의 프로토타입들을 제작해 보았다. 이 연구는 앞으로 제작될 수많은 배너광고의 Interactivity제고와 더 나아가 Ad-Browser(사용자가 배너 안에서 원하는 정보를 찾아 볼 수 있도록 해 주는 배너광고의 형식)의 개발에도 도움을 줄 수 있을 것으로 생각된다. At first Internet is developed for military and academy. However it has been developing in commercial area as the technology has been developing. The banner advertisement can be an exemplary that uses the internet in commercial area. Nowadays a lot of studies come out that pay attention to how the banner advertisement could be made better and more effectively. Nevertheless, the banner advertisement of this time is lack of interactivity which is the most typical character of internet. In this project, we proceeded the study that is for making interactivity of the banner advertisement be in extreme, and made prototypes of the interactive banner advertisement. We expect that this study could help raising interactivity of the banner advertisement, could help developing the ad-browser(a form of the banner advertisement which makes user could search information what they want in the banner).

본 논문에서는 이동통신채널에서 발생하는 간섭현상을 제거하기 위한 적응형 채널추정(adaptive channel estimate) 알고리듬을 제안하였다. 기존 LMS 알고리듬은 입출력사이 오차를 줄이기 위해 사용하는 첫 기준신호의 선택에 따라 수렴속도와 오차정확도에 많은 영향을 받는다. 본 논문에서 제안한 적응형 채널추정 알고리듬은 간섭신호와 유사한 기준신호를 정하기 위해 LMS 알고리듬을 수행하기 전에 병렬의 컨볼루션 연산을 수행한다. 컨볼루션 연산을 통해 출력된 신호는 채널의 지연시간과 진폭특성을 가지고 있어 간섭신호와 유사한 특성을 가진다. 제안된 알고리듬의 성능평가는 이동통신환경과 유사한 Jake's 모델에 Doppler 주파수는 130 ㎐, Random한 5개의 경로가 존재하는 Rayliegh 다중경로 채널환경에서 실험하였다. 모의실험결과 기존 LMS 알고리듬은 데이터 150개를 반복 수행함으로써 약 -40 ㏈의 제곱오차수렴을 보였고 제안한 적응형 채널추정 알고리듬은 데이터 200개를 반복 수행함으로써 약 -80 ㏈의 제곱오차수렴을 보였다. 데이터의 반복연산에 따른 수렴속도는 다소 증가하였으나 제곱오차정확도는 약 40 ㏈의 우수한 개선특성을 보였다. In this thesis , design effective elimination interference algorithm of ICS repeat system for repeater that improve frequency efficiency. Error convergence speed and accuracy of LMS Algorithm are influenced by reference signal. For improve LMS Algorithm, suggest Adaptive channel estimate algorithm. For using channel characteristic, adaptive channel estimate algorithm make reference signal similar interference signal by convolution operation and complement LMS algorithm demerit. For make channel similar pratical channel, apply Jake's Rayleigh multi-path model that random five path with 130Hz Doppler frequency. LMS algorithm and suggested adaptive channel estimate algorithm that have 16 taps apply to ICS repeat system under Rayleigh multi-path channel, so simulate with MATLAB. According to simulate, ICS repeat system with LMS algorithm show -40㎐ square error convergent after 150 datas iteration and ICS repeat system with adaptive channel estimate algorithm show -80㎐ square error convergent after 200 datas iteration. Analyze simulation result, suggested adaptive channel estimate algorithm show more three times iteration performance than LMS algorithm, and 40㎐ accuracy.
