This study was carried out to observe the functional ultrastructures of photoreceptor cells in frog(Rana catesbeiana) retina using transmission electron microscope. The photoreceptor cells are divided into two types-rod and cone cells-consist of outer and inner segment. The long outer segment of rod cell contains dense stacks of membrane and formed vertical and horizontal folds. The outer segment of cone cell is small, and vertical and horizontal folds are not exist. The electron dense cytoplasm of rod cell contains compact mitochondria, Golgi complexes, and endoplasmic reticula. The inner segment of cone cell shows low electron density and contains a large lipid droplet in the upper part of inner segment. In addition, cone cell contains many mitochondria, Golgi complexes. rough endoplasmic reticula, ribosomes and numerous glycogen particles. It is believed that these ultrastructural characteristics are closely associated with photoreceptive function of photoreceptor cells in frog retina.

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.

Purpose: The attachment level is strongly associated with tooth loss and provides useful information on patterns of destruction of the periodontium. The presence of horizontal attachment loss would not be detected in clinical measurement. Therefore, the purpose of the present study was to estimate the patterns of periodontal destruction based on the attachment area and horizontal attachment loss in extracted teeth due to severe periodontitis. Materials and Methods: 307 teeth satisfied the criteria for assessment. An indirect method, based on digital images obtained from a digital camera and an image analysis program, was used to calculate the area of root surface and attachment loss and the extent of horizontal attachment loss. The data were analysed using SPSS. Results: No statistically significant differences among root surfaces were observed in anterior teeth on the loss of attachment area. However, in posterior teeth statistically significant differences in palatal surfaces of maxillary and mandibular premolar and molar surfaces compared with buccal surfaces were observed. Horizontal attachment loss was observed in 21.5% of the teeth examined. Frequency of horizontal attachment loss was highest in the maxillary first premolar (34.8%), followed by the maxillary second premolar (27.3%) and maxillary canine (25%). The mean length of horizontal attachment loss was 1.5mm. Conclusion: More meticulous examination will be needed of the palatal surfaces of maxillary and mandibular premolar and molar teeth. The percentage of teeth with horizontal attachment loss greater than 2.1 mm was 5.2%. Considering the length of curette blades, about 5.2% of teeth were not properly debrided. Therefore, Additional supportive therapy such as local drug delivery has to be considered in treatment of the first maxillary, second premolar and canine due to the high prevalence of horizontal attachment loss.

This study evaluated the physicochemical characteristics of domestic and imported packaged Kimchi in Korea. Six types of domestic and imported Kimchi were collected from a supermarket. According to the results, the salt concentrations of the domestic and imported Kimchi were 3.83% and 3.06%, respectively. The total lactic acid content was 0.33% for domestic Kimchi, and 0.29% for imported Kimchi. The total vitamin C content was found to be higher in the domestic Kimchi (30.9mg%) than in the imported Kimchi(25.9mg%). These results suggest that both are within the standards of the Korea Food and Drug Administration in terms of food containment: 1% or lower for acid, and $1{\sim}4%$ for salt. For the number of aerobic bacteria present in each of them, both contain approximately $10^4{\sim}10^5\;CFU/g$g, which is safely under the FDA standard of $10^7{\sim}10^8 \;CFU/g$. Therefore, neither is harmful at all in terms of the number of bacteria but continuous monitoring will be necessary. from texture analysis, the hardness and chewiness of the domestic Kimchi was better than the imported Kimchi. The hardness and chewiness of the domestic Kimchi indicated a better production process than imported Kimchi. There may not be a particular difference in terms of the sensory evaluation apart from its crispy taste. However, this also needs to be continuously monitored while the Kimchi is undergoing the fermentation process.

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.
