Face Recognition has been an active research area because it is not difficult to acquire face image data and it is applicable in wide range area in real world. Due to the high dimensionality of a face image space, however, it is not easy to process the face images. In this paper, we propose a method to reduce the dimension of the facial data and extract the features from them. It will be solved using the method which extracts the features from holistic face images. The proposed algorithm consists of two parts. The first is the using of principal component analysis (PCA) to transform three dimensional color facial images to one dimensional gray facial images. The second is integrated linear discriminant analusis (PCA+LDA) to prevent the loss of informations in case of performing separated steps. Integrated LDA is integrated algorithm of PCA for reduction of dimension and LDA for discrimination of facial vectors. First, in case of transformation from color image to gray image, PCA(Principal Component Analysis) is performed to enhance the image contrast to raise the recognition rate. Second, integrated LDA(Linear Discriminant Analysis) combines the two steps, namely PCA for dimensionality reduction and LDA for discrimination. It makes possible to describe concise algorithm expression and to prevent the information loss in separate steps. To validate the proposed method, the algorithm is implemented and tested on well controlled face databases. 영상 인식은 영상획득이 용이하다는 것과 실생활에서 광범위하게 사용될 수 있다는 것으로 인해 활발하게 연구되고 있는 분야이다. 그러나 얼굴영상은 높은 차원의 영상공간으로 인해 이미지 처리가 쉽지 않다. 본 논문은 얼굴 영상 데이터의 차원을 특징적인 벡터로 표현하고 이러한 특징벡터를 통해 얼굴 영상을 인식하는 방법은 제안한다. 제안되는 알고리즘은 두 부분으로 나뉜다. 첫째로는 칼라 영상을 그레이 영상으로 변환할 때 RGB 세 개의 플레인의 평균이 아닌 세 플레인의 주성분을 사용하는 PCA(Principal Component Analysis)를 적용한다. PCA는 칼라 영상을 그레이 영상으로 변환하는 과정과 인식률을 높이기 위한 영상 대비 개선 과정이 동시에 수행한다. 두 번째로는 PCA와 LDA(Linear Discriminant Analysis) 방식을 하나의 과정으로 통합하는 개선된 통합 LDA 방법이다. 두 과정을 통합함으로서 간결한 알고리즘 표현이 가능하며 분리된 단계에서 있을 수 있는 정보 손실을 방지할 수 있다. 제안된 알고리즘은 잘 제어된 대용량 얼굴 데이터베이스에서 개인을 확인하는 분야에 적용되어 성능을 향상시키고 있음을 보여주었고, 추후에는 실시간 상황에서 특정 개인을 확인하는 분야의 기초 알고리즘으로 적용될 수 있다.

Dental implants have been widely used in the treatment of esthetic and functional problems of the mouth due to alveolar bone loss, after tooth extraction. The success of implantation strongly depends on osseointegration. For osseointegration, implant material, methodology, and design have been investigated. For materials, two popular materials at present are titanium and hydroxyapatite. For methods, immediate implantation is being used recently. The purpose of this study is to evaluate osseointegration between the unthreaded cylindrical TPS implant and the HA-coated implant by a histomorphometric analysis. For this analysis, experimental periodontits was induced on the 3, 4 premolars of adult dogs by the ligation of orthodontic threads. Thereafter, each tooth was extracted. TPS. Implants and HA-coated implants were immediately inserted in the extraction socket. In control group, TPS implants were immediately inserted, and In experimental group, HA implants were immediately inserted. The dogs were sacrificed after 12 weeks, then the specimens were prepared for LM and histomorphometric analysis. The conclusion of this study is as follows l. In both control and experimental group, no inflammatory cells were observed. 2. The results of the histomorphometric analysis showed that the total osseointegration was 48.5% in control group, and 68.8% in expermental group. The experimental group was higher than the control group, and the difference was not statistically significant (p<0.05). 3. The results of the histomorphometric analysis showed that the osseointegration in the hole was 40.6% in control group, and 70.2% in experimental group. The experimental group was higher than the control group, and the difference was statistically significant (p<0.05). In both control and experinental group, no inflammatory cells were observed. 4. The results of the histomorphometric analysis showed that the osseointegration in the lower part was 52.1% in control group, and 73.3% in experimental group. The experimental group was higher than the control group, and the difference was statistically significant (p<0.05). 5. In experimental group, the bone to HA interface seemed to be mixed of bone and HA. We could not distinguish HA from the bone. The HA coating was detached from the titanium surface.

본 연구의 목적은 말지각평가의 기초 자료가 되고 청각장애 자음지각능력의 정량적 정성적 평가가 가능한 음소단위의 한국어자음지각검사 (Korean Consonant Perception Test, 이하 KCPT)도구를 개발하는 것이다. KCPT는 조합 가능한 모든 한국어 단음절어 중 유의미 단음절어만 분류하여, 7종성발음규칙을 적용하고 목표단어의 친숙도를 조절한 사지선다형 초 종성검사문항 시안을 작성한 후, 각 단어들의 조음 특성, 난이도, 음소 출현빈도수를 고려하여 완성되었다. 이를 정상인 20명을 대상으로 평가하여 난이도가 높은 문항을 제거하고 화자 간 변수가 없는 것을 통계적으로 확인한 후 회화체 빈도수에 맞도록 최종문항을 작성하였다. 세부적 수정을 거쳐 초 종성검사문항 각 200개와 100개로 구성된 총 300개 문항을 개발하였다. 30명의 청각장애인을 대상으로 검증하여 A와 B로 구분한 절반목록간 차이도 없음을 확인하고 초성검사문항은 초성자음지각평가에 종성 검사문항은 종성자음 지각평가에 적절한 도구임을 검증하였다. The purpose of this study was to develop Korean Consonant Perception Test (KCPT), that is a phonemic level including elementary data to evaluate speech and consonant perception ability of the normal and the hearing impaired qualitatively and quantitatively. KCPT was completed with meaningful monosyllabic words out of possible all Korean monosyllabic words, considering articulation characteristics, the degree of difficulty, and the frequency of the phonemic appearance, after assembling a tentative initial and final consonants testing items using four multiple-choice method which were applied to the seven final consonant regulation and controlled with the familiarity of the target words. Conclusively, the final three hundred items were developed including two- and one-hundred items for initial and final testing items, respectively, with the evaluation of the 20 normal hearing adults. Through this process, the final KCPT was composed upon the colloquial frequency following identification of no speakers' variances statistically and elimination of the highly difficult items. The 30 hearing impaired were tested with KCPT and found that the half lists, A and B, were not different statistically and the initial and final testing items were appropriate for evaluating initial and final consonants, respectively.

This study investigates sound, scenery, and soundscape preferences, which are sensory factors that users feel in a healing forest, comparing the difference in recovery by the soundscape. In the barrier-free, wooden walking path of the National Daegwallyeong Healing Forest, a survey site with five different conditions was selected. Users prefer water sounds the most and places with open views for scenery. For the complex sensation of soundscapes, the most preferred is a space where water sounds can be heard, and either a waterfall or an open view can be seen. A profile of mood states test was use to compare users' psychological recovery by the soundscape. It was found that users felt the most positive mood with water sounds and open views. In addition, users' preference for artificial sounds, scenery, and soundscape was the lowest. In the mood state test, it was found that the artificial soundscape incited the most negative emotions.
