MPEG-4 for an object base coding after extracting the region from image, the coding for a real-time requirements is quick and must be accurate. The object crisis algorithms of existing calculation quantity are many and with image transformation or video conferencing system to same real-time application they are not suitably. The object real-time tracking it tried to apply the CAM-Shift algorithm which is possible from the dissertation which it sees consequently. Tracking the object which it moves or wants the VO where (Video Object) tracking the user wants in bounding box form defines the object where is started. Tracking the object of after uses a CAM-Shift algorithm and are extracted and the VOP with the VO which it is composed. It defines one bounding box with the method which is proposed consequently about lower only one VOP there to be it will be able to compose, it becomes.

Generally, pyridine and most of substituted pyridines act as base in aqueous solutions. The strengths of their basicities can be expressed quantitatively by the dissociation constant of base or its conjugated acid. Generally, the acidity of substituted pyridines can be expressed by K_a of the following reaction. ◁그림삽입▷(원문을 참조하세요) The dissociation constants of these subtituted pyridines have not been reported under high pressure but under atmospheric pressure. In this papers, the dissociation constants of some substituted pyridines were measured under high pressure by the conductometry. From the ionic conductivity of hydrogen ion, the dissociation constants(K_a) were calculated. The K_a values were increased with increasing temperature and were decreased with increasing pressure. The characteristics of dissociation process of some substituted pyridines were deduced from the thermodynamic properties calculated from the dissociation constants.

본 연구의 목적은 흰쥐 상악 대구치를 발거하여 자기장 저속 냉동보관법을 이용하여 냉동 시 치주인대세포의 활성도 및 세포 사멸도를 MTT검색법과 TUNEL검사를 이용하여 측정하고자 하였다. 4주령의 암컷 Sprague-Dawley계 된 쥐의 상악 좌우 제1,2대 구치를 발거하여 각군 당 12개의 쥐 치아를MTT검색에 이용하였고 6개의 치아를 TUNEL 검사에 이용하였다. 실험군은 5개군으로 대조군은 즉시 발치군이며 4℃냉장고에서 1주일간 보관한 냉장군, 발치 후 동해방지제 처리과정을 거쳐 -196℃의 액화질소에 넣어 급속 냉동한 액화질소군, 21.7 ㎃, 60 ㎐, 1 G의 자기장을 이용하여 -0.3℃/min 의 속도로 -20℃까지 냉동 후 -196℃로 급속 냉동한 자기장군, -0.3℃/min의 속도로 -20℃까지 냉동 후 -196℃에 급속 냉동한 저속 냉동군으로 나누었다. 보존액은 F medium을 사용했으며 동해방지제로 10% dimethyl sulfoxide (DMSO)를 사용하였다. 치근면을 단위면적으로 표준화하기 위해 MTT측정값을 Eosin 염색 후 530 ㎜에서 측정한 흡광도 값으로 나누었다. TUNEL 검사 시 각 조직슬라이드에서 400배 크기의 현미경 시야에서 임의로 세 부분을 지정하여 정상 세포수와 양성 세포수를 세어 그 비율을 계산하여 각 실험군 당 평균치를 구하였다. 통계 분석을 위해 one way ANOVA를 시행하였으며 사후검정으로 Scheffe와 Tukey HSD방법을 썼으며 결과는 다음과 같다. MTT검색에 의한 흡광도를 Eosin염색 후 측정한 흡광도로 나눈 값에서는 자기장군은 즉시 발치군보다 낮은 세포활성을 보였고 (p < 0.05) 액화질소군, 저속 냉동군과는 통계적으로 유의성 있는 차이를 보이지 않았다. 그러나 자기장군은 액화질소군, 저속 냉동군과 함께 냉장군보다는 높은 세포 활성도를 보였다 (p<0.05).TUNEL검사 결과도 자기장군은 즉시 발치군보다 치주인대의 세포사멸도가 높았으나 (p < 0.05) 저속 냉동군과 액화 질소군과는 통계적으로 유의한 차이를 보이지 않았다. 자기장군은 냉장군보다 세포사멸도가 낮았으며 냉장군은 모든 군 중에서 세포 사멸도가 가장 높았다 (p<0.05). The purpose of this study was to evaluate the viability of periodontal ligament cell in rat teeth using slow cryopreservation method with magnetic field through MTT assay and TUNEL test. For each group, 12 teeth of 4 weeks old white female Sprague-Dawley rat were used for MTT assay, and 6 teeth in TUNEL test. The Maxillary left and right, first and second molars were extracted as atraumatically as possible under tiletamine anesthesia. The experimental groups were groupl (immediately extraction), group 2 (cold preservation at 4℃ for 1 week), group 3 (rapid Cryopreservation in liquid nitrogen), group 4 (slow cryopreservation with magnetic field of 1 G), and group 5 (slow cryopreservation). F medium was used as preservation medium and 10% DMSO as cryoprotectant. After preservation and thawing, the MTT assay and TUNEL test were processed. One way ANOVA and Scheffe method were performed at the 95 % level of confidence. The value of optical density obtained after MTT analysis was divided by the value of eosin staining for tissue volume standardization. In both MTT assay and TUNEL test, it had showed no significant difference among group 3,4, and 5. And group 3 had showed higher viability of periodontal ligament cell than group 2. From this study, slow cryopreservation method with magnetic field can be used as one of cryopreservation methods.

유산 완충용액의 pH 및 포화도 변화에 따른 법랑질 내 수산화인회석 결정 형태의 변화

Since it was reported that incipient enamel caries can be recovered, previous studies have quantitatively evaluated that enamel artificial caries have been remineralized with fluoride, showing simultaneously the increase of width of surface layer and the decrease of width of the body of legion. There is, however, little report which showed that remineralization could occur without fluoride. In addition, the observations on the change of hydroxyapatite crystals also have been scarcely seen. In this study, enamel caries in intact premolars or molars was induced by using lactic acidulated buffering solutions over 2 days. Then decalcified specimens were remineralized by seven groups of solutions using different degree of saturation (0.212, 0.239, 0.301, 0.355) and different pH (5.0, 5.5, 6.0) over 10 days. A qualitative comparison to changes of hydroxyapatite crystals after fracturing teeth was made under SEM (scanning electron microscopy) and AFM (atomic force microscopy). The results were as follows : 1. The size of hydroxyapatite crystals in demineralized area was smaller than the normal ones. While the space among crystals was expanded, it was observed that crystals are arranged irregularly. 2. In remineralized enamel area, the enlarged crystals with various shape were observed when the crystals were fused and new small crystals in intercrystalline spaces were deposited. 3. Group 3 and 4 with higher degree of saturation at same pH showed the formation of large clusters by aggregation of small crystals from the surface layer to the lesion body than group 1 and 2 with relatively low degree of saturation at same pH did. Especially group 4 showed complete remineralization to the body of lesions. Group 5 and 6 with lower pH at similar degree of saturation showed remineralization to the body of lesions while group 7 didn't show it. Unlike in Group 3 and 4, Group 5 and 6 showed that each particle was densely distributed with clear appearance rather than crystals form clusters together. 법랑질 초기 우식이 회복된다는 것이 보고된 이래 법랑질에 대하여 불소를 첨가한 상태에서 행했던 이전의 연구들은 법랑질 인공우식의 재광화가 표면층의 증가와 함께 병소본체의 폭 감소가 일어난다는 정량적인 평가는 많이 하였으나 불소를 첨가하지 않은 상태에서는 재광화가 일어났다는 연구는 부족하였고, 또 수산화인회석 결정의 입자 변화에 대한 관찰도 미비하였다. 본 연구는 탈회나 균열이 없는 소구치 및 대구치를 대상으로 탈회 완충용액을 이용하여 법랑질을 2일간 탈회시키고, pH와 포화도가 상이한 7가지 유산 완충용액으로 10일 동안 재광화를 유도한 후 치아를 파절시켜 수산회인회석 결정의 변화를 원자현미경과 주사전자현미경을 이용하여 정상적으로 비교 관찰하여 다음과 같은 결과를 얻었다. 1. 탈회된 부위에서 관찰된 수산화인회석 결정은 정상적인 수산화인회석 결정보다 크기가 작았으며 결정 사이의 공간이 증가하면서 결정들이 불규칙하게 존재하는 것이 관찰되었다. 2. 재광화된 부위에서는 탈회에 의하여 형성된 빈 공간에 작은 수산화인회석 결정이 새로 침착되는 양상과 결정들이 융합하여 다양한 모습을 갖는 더 커진 결정들을 관찰할 수 있었다. 3. 동일한 pH에서 포화도가 더 높은 3군, 4군은 1군, 2군에 비하여 표면층에서부터 병소본체까지 작은 결정들이 모여 큰 cluster를 형성하였으며 특히 4군에서는 병소본체까지 완전한 재광화가 일어났다. 비슷한 포화도에서는 pH가 더 낮은 5군, 6군은 7군에 비하여 병소본체까지 재광화가 일어났으며 3군, 4군처럼 결정들이 모여 cluster를 형성하기보다는 개개의 입자들이 뚜렷한 외형을 가지며 매우 치밀하게 분포되어 있었다.

This paper is the eye region which is used with confirmation element of face image it uses the SIFT and it extracting method proposes. The eye region image where becomes model and it composes the keypoint descriptor which is a SIFT result of the input image which it will extract. It uses the keypoint descriptor which and creates it composes a each feature vector, and the judgement where affine transform should have existed on after two feature points which adjusts with each other, against the feature point field which confront above half as the case eye region where the with each other same affine transform will exist it judged. There is not a test result learning process, more quickly recognition method of existing methods than the possibility of getting the result which extracts the region it was.
