손 영역 추적에서는 피부색이 가장 유용한 정보 중 하나이다. 그런데 손 영역과 얼굴 영역이 서로 겹치거나 가까이 있을 때 손 영역의 추적결과인 바운딩이 얼굴 영역까지 불필요하게 확장되는 문제점이 존재한다. 본 논문에서는 얼굴 영역 추적결과를 손 영역 추적에 사용한다. 구체적으로, 얼굴 영역 내에 손 영역의 바운딩이 침투하지 않도록 한다. 실험결과, 얼굴 영역 추적결과를 사용한 경우 그렇지 않은 경우에 비해 손 영역의 바운딩을 정확히 예측하였으며 초당 30~35 프레임의 빠른 계산속도를 유지하였다.

Objectives: The purpose of this study is to document the stress of the traffic accident patients. Methods: Clinical study was carried out on 35 traffic accident patients. To measure stress score, questionnaire was done by using State-Trait Anxiety Inventory(STAI-I, II), Beck Depression Inventory(BDI), Impact of Event Scale(IES). The pain score after the traffic accident was measured by Visual Analogue Scale(VAS). Results: STAI-I, II, BDI, IES scores of the traffic accident patients were higher than normal limit and those of normal people in other studies about the stress. VAS score and duration after traffic accident showed no significant correlation with STAI-I, II, BDI, IES scores. Conclusions: Without regard to pain and duration after traffic accident, stress could be caused by traffic accident. More considerations on stress should be needed in treatment of the traffic accident patients.

Purpose: We report the first case in Korea of rapid bone formation on a subperiosteal orbital hematoma after trauma. Case summary: A 10-year-old boy who was in the intensive care unit after trauma showed proptosis and ocular movement limitation of the right eye associated with subperiosteal hematoma. On ocular examination, 3 mm of proptosis and limitation of right eye movement were observed; however, visual acuity was not decreased. At 1 month after the trauma, orbital computed tomography (CT) showed new bone formation at the margin of the hematoma border although the size of the hematoma decreased. The patient underwent hematoma and bony tissue removal using anterior orbitotomy approach. A new bone was formed between the orbital border and hematoma from the anterior orbital margin to the orbital apex. During pathological examination, woven bone tissue with fibrotic tissue was observed in the hematoma wall. One year after surgery, the patient’s proptosis and limitation of ocular movement disappeared without any evidence of new bone formation. Conclusions: Waiting for spontaneous absorption of orbital subperiosteal hematoma is usually recommended unless there is significant functional impairment. However, as in our case, new bone formation could occur during a short period of less than 1 month; imaging follow-up is necessary in patients having intensive care or showing delayed absorption of a hematoma.

Objectives : This study was designed to compare depletion and cupping therapy with cupping therapy on acute lumbosacral strain patients. Methods : This study was carried out on the 36 acute lumbosacral strain patients. We divided these patients into 2 groups. The GroupⅠ was treated with the depletion and cupping therapy and the GroupⅡ was treated with the cupping therapy. We evaluated by visual analogue scale(VAS) score after each treatment and Oswestry disability index(ODI) score before and after treatment. Result : The VAS score of GroupⅠ was statistically lower than GroupⅡ after 1st treatment. But there was no significant difference between two groups after 2st treatment. In each group, the VAS score and ODI score was statistically decreased after treatment. Conclusions : In this study, depletion and cupping therapy was more effective than cupping therapy after 1st treatment, but there was no difference between two kinds of cupping therapy after 2nd treatment on acute lumbosacral strain patients.
