디지털 워터마킹은 멀티미디어 데이터의 저작권 보호 목적으로 최근에 많은 연구가 진행되고 있다. 본 논문에서는 디지털 영상에 저작권 정보를 은닉하는 디지털 워터마킹 방법의 기법을 고찰한다. 웨이브릿 변환 영역에서 각 대역에 삽입된 워터마크는 영상 압축 등의 처리과정을 거치면서 변형이 생기게 되는데, 영상처리 후에 각 대역의 통계적 특성에 따라 변형정도가 다르게 된다는 특성을 고려한다. 이를 통해 영상의 대역 특성에 따라 워터마크를 다르게 삽입해야 좋은 결과를 얻을 수 있음을 알 수 있다. Recently, many studies about digital watermarking have been doing, and their purpose is to protect copyright of multimedia data. In this paper, the performances of digital watermarkings, in order to hide information of copyright into digital images, are analyzed. The watermarks embedded in subbands on wavelet transform domain are transformed by the processing such as image compression, and the degree of the transformation in each subband depend on its statistical characteristics. That says, we must consider the characteristics of subbands for better watermarking.

본 논문에서는 부호책의 계산 복잡도를 감소시키기 위하여 SOM의 처리 과정에서 발생되는 정보를 이용하는 고속 탐색 알고리듬을 제안한다. 부분 거리 탐색의 성능을 부호책의 재배열 영향을 입증하기 위해 3가지 경우의 배열에 의한 계산 시간 감축의 효과를 보인다. In this paper, in order to reduce the computational complexity of codebook, we propose a fast search algorithm which takes advantage of the information generated in the process of the self-organizing map (SOM). In an attempt to demonstrate the influence of the ordering of codebook on the performance of the partial distance search (PDS), we present the results of computation savings for three cases of ordering of codebooks.

The author investigated clinically and radiographically the 57 children, who have mesiodens, aging from 3 years to 12 years 2 months among the children who had visited the Dept. of Pedodontics, Seoul National University Hospital. The following results were obtained. 1. The mesiodentes were more frequent in male than in female, and more frequent in maxilla than in mandible. 2. The mesiodentes which erupted into oral cavity were 53.1 percent, and upright mesiodentes were 75.3 percent. 3. The shapes of mesiodentes were as follows: Conical shape was 56.8 percent, round shape was 17.3 percent, tuberculated shape was 14.8 percent, incisor-like shape was 6.2 percent, and canine-like shape was 4.9 percent. 4. The relationship between mesiodentes and neighboring teeth, and the complications which mesiodentes caused were as follows: non-specific influence was 48.2 percent, delayed eruption of neighboring tooth was 16.5 percent, crown rotation of neighboring tooth was 11.8 percent, median diastema was 10.5 percent, angulation of neighboring tooth axis was 3.5 percent, crowding of neighboring tooth was 2.4 percent, root underdevelopment of neiboring tooth was 2.4 percent, and the associated lesion with mesiodens did not exist.

서울시내에 거주하는 13세-15세 청소년들의 부정교합에 관한 역학적 연구
송경원,김진태 大韓小兒齒科學會 1984 大韓小兒齒科學會誌 Vol.11 No.1
Childrens between the ages of 13 and 15 years, living in Seoul, were examined in order to determine the prevalence and severity of malocclusion in the permanent dentition. This survey encompassed 981 children and an individual chart was prepared for each subject recording an original HMAR score and classification of occlusion according to Angle. Also, subjective evaluation of "treatment needs" was carried out in 581 children. The results were as follows: 1. Of the 981 children in this survey, 12.1 percent showed excellent occlusion. (0 point) 2. The 14 percent of the children who had a score of 24 and above all appeared to belong to the "treatment highly desirable" or "treatment mandatory" category. 3. The incorporation of SAR (Supplementary Assessment Record) into the HMAR can provide more sensitive method for evaluating severity of malocclusion. 4. According to Angle's classification 77.4 percent of all malocclusion belonged to Class Ⅰ, 1.3 percent to Class Ⅱ, Division 1, 0.9 percent to Class Ⅱ, Division 2, and 11.3 percent to Class Ⅲ. 5. The mean HMAR score for Class Ⅰwas significantly lower than for either Class Ⅱ, Division 1 or Class Ⅲ. (P<0.05) 6. A close relationship was found between the degree of "treatment needs" and the value obtained by the HMAR scoring. (chi-square test, p<0.05) The differences between the mean HMAR scores of the various subjectively defined categories were statistically significant. (p<0.001)

투영과 기울기 보정을 이용한 얼굴 및 얼굴 요소의 특징 추출
김진태,김동욱,오정수 한국정보통신학회 2003 한국정보통신학회논문지 Vol.7 No.3
본 논문은 얼굴 인식을 위한 얼굴 요소 및 얼굴 특징점을 추출하는 방법을 제안한다. 얼굴 요소는 피부색을 이용하여 추출된 얼굴 영역에서 요소들간의 기하학적 정보를 이용하여 후보 영역을 정하고 후보 영역에서 요소들이 갖고 있는 고유 특성들을 이용하여 추출해 간다. 얼굴 인식에 적용된 얼굴 특징점은 추출된 얼굴 요소들간의 거리, 각 등의 기하학적인 관계로 나타낸다. 실험 결과, 얼굴 구성요소 추출이 잘 되었다. This paper proposes methods to extract face elements and facial characteristics points for face recognition. We select a candidate region of the face elements with geometrical information between them inside the extracted face region with skin color and extract them using their inherent features. The facial characteristics to be applied to face recognition is expressed with geometrical relation such as distance and angle between the extracted face elements. Experiment results shows good performance to extract of face elements.

The materials were 87 dental casts of 3 and 4-year-old children with normal occlusion. Arch forms and sizes of primary anterior dentition were measured on tracing papers. The following conclusions were obtained from the investigation. 1. The arch form of primary dentition was a partial circle. 2. The average radius of primary anterior arch was 17.96mm in maxilla and 15.07mm in mandible. 3. Primary lateral incisors were 0.14mm inward from the arch in maxilla dentition and 0.05-0.09mm outward from the arch in mandible dentition. 4. Primary cuspids were almost on the arch in maxilla dentition and 0.2-0.3mm outward from the arch in mandible dentition.
