Purpose: The aim of this study was to retrospectively evaluate the clinical and radiological results of the first metatarsophalangeal joint arthrodesis with two crossed screws fixation. Materials and Methods: We treated 23 patients (24 cases) with arthrodesis of the first metatarsophalangeal joint using two crossed screws fixation between December 2000 and May 2005. There were 3 male patients and 20 female patients. Ages ranged from 28 to 74 years (mean, 50 years). Follow-up ranged from 4.1 to 8.2 years (mean, 6.5 years). The American Orthopaedic Foot and Ankle Society (AOFAS) score and their satisfaction was evaluated clinically, foot anteroposterior and lateral radiograph, radiologically. Results: Of the 24 cases, 6 had surgery for dorsal plate and screws fixation because of failure to acquire firm fixation with two crossed screws fixation. All 6 cases acquired bony union. Fusion of the hallux first metatarsophalangeal joint occurred in 16/18 cases (89%). Nonunion occurred in 2 cases (11%) and was asymptomatic. At last follow-up, hallux valgus angle ranged from 11 to 25 degrees(mean, 17.7 degrees), dorsiflexion ranged from 15 to 25 degrees (mean, 22 degrees).The mean preoperative AOFAS score of 37 points(range, 28 to 45 points) improved to a mean of 77 points (range, 65~90 points) postoperatively. The result of the procedure as rated subjectively by the patient was excellent for 5 cases, good for 11 cases and fair for 2. Conclusion: Comparatively, the arthrodesis of the first metatarsophalangeal joint with crossed screws fixation showed a satisfactory clinical results, we thought that require technical attention for firm fixation in operation.

목적: 척추경 나사못 고정술후 나사못 주위에 발생한 방사선 투과대가 가지는 임상적 의의를 후향적 연구를 통해 알아보고자 하였다. 대상 및 방법: 2003년 5월부터 2005년 12월까지 퇴행성 요추 질환으로 척추경 나사못 고정술 및 후측방 유합술을 받은 환자 중 2년 이상 추시가 가능하였던 124예를 대상으로 하였다. 방사선 투과대의 관찰은 단순 방사선 사진을 이용하여 단분절(2분절 이하), 장분절(3분절 이상) 및 천골 고정 유무에 따라 4개의 군으로 나누었다. 골다공증, 나사못의 위치, 골유합 정도, 천골의 전방 피질골 고정 유무에 따라 비교 분석하였다. 결과: 124예 846개의 나사못 중 71 (57%)예, 189 (22%)개의 나사못에서 투과대가 관찰되었으며 천골 고정을 시행한 경우 151개 (27%), 천골 고정을 시행치 않은 경우 38개(13%)로 통계적 차이(p=0.001)를 보였다. 나사못 주위 투과대는 천골 고정시 전방 피질골 고정을 시행한 경우 및 골유합이 보다 잘 되었을 경우 통계학적으로 감소하였으며 골다공증(T score: -2.5 이하)이 있는 경우에는 660개 중 157개(24%)로 증가하는 소견을 보였다. 결론: 척추경 나사못 고정술후 나사못 주위에 발생 가능한 방사선 투과대는 천골을 포함한 고정 유합술, 가관절증과 관련하여 흔하게 나타났으며 대부분 완전 골유합 이전에 나타났다. 골다공증 및 천골 고정시 고정 술식 등 다양한 요소를 고려해야 하며 완전 골유합 이후에도 진행하는 경우에는 주의 깊은 추시 관찰이 필요할 것으로 사료된다. Purpose: We wanted to retrospectively evaluate the clinical significance of radiolucent zones surrounding the pedicle screws after spinal fusion. Materials and Methods: Spinal surgery was performed between May 2003 and December 2005 on elective patients with degenerative lumbar disorders and they underwent transpedicular screw fixation and posterolateral fusion and these patients were the subjects of the study. There were 124 cases with more than 2 years of follow up. Determination of the radiolucent zones around pedicle screws was done using simple x-rays and the cases were divided in to 4 different groups: segmental fixation with short (2 or less segments) or, long (3 or more segments) segmental fixation and those cases with or without sacral fixation. Comparative analysis was done according to osteoporosis, the location of the pedicle screws, the degree of bony-union and fixation of the anterior cortex of the sacrum. Results: Among the 124 cases and 846 pedicle screws, 189 pedicle screws (22%) had radiolucent zones; 151 of the 189 pedicle screws with a radiolucent zone (27%) were in the sacral fixed group, while 38 of the 189 pedicle screws with a radiolucent zone (13%) were in the non-sacral fixed group, and the difference was significant (p=0.001). In the case of anterior cortical fixation in the sacral fixed group and the complete bony-union, the radiolucent zones had a significantly lower incidence, while the group of patients with osteoporosis (a T score lower than -2.5) had a higher incidence of radiolucent zones. Conclusion: The radiolucent zones surrounding the pedicle screws after spinal fusion were closely related to spinal fusion with sacral fixation and pseudarthrosis, and these radiolucent zones mostly occurred before complete bony-union. The existence of osteoporosis and the techniques of sacral fixation and many different contributing factors must be considered, and careful monitoring is needed even if the radiolucent zone progressive after complete bony-union.

최근 모바일 기기에서 입력방식으로 사용되기 시작한 멀티터치 입력방식은 지금까지와는 다른 다양한 방식의 입력을 가능하게 하였다. 기존 싱글 터치 입력 방식을 사용한 모바일 한글 입력방식의 특징을 파악하고 이를 기반으로 멀티터치 입력방식에 접목시켜 한글 입력방식을 연구함으로써 좀 더 직관적이고 차별화된 인터페이스를 제안한다.

The purposes of this study were to investigate the physicochemical characteristics and storage stabilities of various sauces with added Yuza(Citrus Junos). Yuza consisted of three parts: peeled (46.17%), fleshed (43.74%) and seeded (10.09%). Yuza juice revealed 11.33% extraction yield, pH 2.85, 4.18% total acidity, 11° Brix, 1.16% transmittance and 2.63° Brix/acid ratio. Five kinds of sauces with added Yuza juice were Yuza red pepper paste sauce, Yuza soybean sauce for meat, Shahu shabu Yuza sauce, Korean Yuza vegetable sauce and Japanese Yuza soybean sauce. These sauces showed slight changes in pH, total acidity, total bacterial counts and overall sensory characteristics during storage period (60 days). In conclusion, Yuza juice could be applied to various sauces, which remained usable for 60 days.
