본 논문에서는 단일 카메라를 이용하여 차량의 위치를 검출하고 연속적으로 입력되는 영상에서의 차량의 움직임을 추적하는 알고리즘을 제안한다. 차량의 특징을 검출하기 위해 대표적으로 사용하는 SIFT와 SURF 알고리즘보다 성능이 좋은 Ferns 알고리즘을 사용하고 Optical Flow Tracker를 이용하여 차량의 위치를 추적한다. 신뢰도를 높이기 위해서 이전 프레임에서 학습되지 않은 특징에 대해 지속적으로 학습하여 새로운 학습결과를 도출하여 업데이트한다. 기존의 차량 검출 알고리즘보다 본 논문에서 제안하는 알고리즘이 Ferns에 의한 학습과 Optical Flow Tracking의 상호작용으로 높은 매칭률과 효율성을 보였다.

Influences of diphenhydramine on the contractile response of isolated rat auricle to norepinephrine were studied in order to clarify the mechanisms of depressant and stimulant actions of diphenhydramine. 1. Large dose of diphenhydramine(10μM) potentiated the contractile action of norepinephrine but small dose of diphenhydramine suppressed the contractile action of norepinephrine. 2. Cocaine did not affect, the stimulant action of diphenhydramine, but reversed the depressant action of this drug. 3. Ouabain did not affect the excitory and inhibitory action of diphenhydramine. 4. Verapamil did not change the excitory and inhibitory action of diphenhydramine. From the above results, it has appeared that diphenhydramine has stimulant ant depressant action on the contractile action of norepinephrine, and it is suggested that the potentiation of norepinephrine action by diphenhydramine is due to inhibition of amine pump, but the inhibition of norepinephrine action by diphenhydramine is not related to modification of amine pump or Ca flux.

Dermoid cyst in one of the rare diseases in the floor of the mouth. The dermoid cysts arise from epithelium that has been enclaved in the tissue either on closure of embryogenic processes of from traumatic implantation. Most othen these events occur shortly after birth and the development of these cysts occur during the period of increased activity of epithelial tissues. The increased activity of the epithelial growth coincides with the ages of 15 to 35 years, when most of these lesions occur. They project into the floor of the mouth, or into the neck behind the chin, or both. Recently the authors had experienced a dermod cyst in the floor of the mouth.

Objectives:The purpose of this study was to examine the relationships of anxiety& depressive symptoms according to the severity of alcohol use in patients with alcohol use disorder. Methods:A total of 85 patients with alcohol use disorders were enrolled in this study. The severity of alcohol use was measured by the Korean version of alcohol use disorders identification test(AUDIT-K)& National Alcohol Screening test(NAST). Anxiety and depressive symptoms were measured by using the Beck Anxiety Inventory(BAI) and the Beck Depression Inventory(BDI), respectively. Pearson’s correlation test was applied to correlate among the severity of alcohol use, anxiety and depressive symptoms. Results:The mean scores of AUDIT-K, NAST, BAI and BDI were 22.22(±8.28), 6.24(±3.25), 18.64(±13.08), and 22.05(±10.13), respectively. Pearson’s correlation test showed that between the score of AUDIT-K and NAST, BAI or BDI, there were positively significant correlations(r=.534, p<.01 r=.231, p<.05 r=.334, p<.01), respectively. And in cases of≥26 score of AUDIT-K, there were much more positive correlations with BAI(r=.425, p<.05). Conclusion:The results of this study demonstrated that patients with alcohol use disorders have high co-morbid anxiety and depressive disorders. Overall, the greater severity of alcohol use may be associated with more anxiety and depressive symptoms. However, it is suggested that in the patients with severe alcohol use, correlation appeared to be positive only for anxiety symptoms.
