In this paper, we propose an interactive system that generates emotional expressions from arm gestures. By extracting relevant features from key frames, we can infer emotions from arm gestures. The necessary factor for real-time animation is tremendous frame rates. Thus, we propose processing facial emotion expression with 3D application for minimizing animation time. And we propose a method for matching frames and actions. By matching image sequences of exagerrated arm gestures from participants, they feel that they are communicating directly with the portraits.

There has been a lot of research into the essence of the smile, but so far just a few studies have been done on the relationship between personality and smile. On the assumption that smile aesthetics are closely related to individual physical condition and psychological state, this study investigated the correlation between personality factors and smile scores. The Personality Factor Questionnaire test was administered to 60 university students (male : 30, female : 30) who have no teeth missing, no experience of orthodontic or prosthodontic treatment and good dentition. Then, portraits were taken in a full smile. Esthetic smile scores were estimated by 10 appraisers who were dentists. These scores were analyzed statistically using the SAS program. The following results were obtained. 1. Personality factors of Warmth, Stableness, Surgency, Boldness, Untroubled-adequacy, Group-dependence, Relaxation, Extraversion, Low anxiety were positively correlated to the aesthetic level of smile. 2. For females, personality factors had greater influence on smile aesthetics, whereas male smile aesthetics were less influenced by personality factors.

Painting is well regarded as a stratified structure by the conservators and restorers. Hence, the scientific methods have been developed for the study of the interal layer of paintings. Examples of such methods are X-ray, infra-red, and ultra-violet photography. A more direct method is to look at the painting in cross section under the microscope and to analyze pigments using an electron probe X-ray micro analyzer(EPMA).In this research, I study and analyze twenty two Korean paintings of self-portraits including the first oil painting of Hui Dong Koh's self-portrait stored in the museum of Tokyo National University of Fine Arts and Music, employing these scientific techniques. The small fragments taken from the ground layers of the early oil paintings(1915∼1942)are analyzed using the EPMA. According to their main materials, the ground layers can be classified into five types ; 1. Lead white layer and double layer of calcium carbonate and lead white, 2. Zinc white with some mixiture of lead white, 3.Titanium white with some barium white, 4. Barium white, 5.Double layer of titanium white and zinc white.

It is very important to preserve the form of traditional costumes and to set the prototype for the design and production of various Korean costumes. This study therefore attempts to analyze the Danryeung pattern methods in textbooks in order to propose a prototype of Korean costumes and a system suitable for modern men, focusing on the Danryeung of the Joseon Dynasty. The research method examined the flow of the Danryeung system in the Joseon Dynasty through previous studies and literature, and the portrayal of the appearance of people of the time through portraits and paintings. The purpose of this study is to analyze the measurements and patterns of textbooks' Danryeung based on the analysis of characteristics of the 5th Joseon Dynasty. From that, the study will analyze the differences between textbooks and artifacts and will propose a Danryeung system for the body shape of modern males in their 30s. In this study, it is meaningful to propose the guideline for the design modification of Korean costumes by providing basic data for subsequent productions.

This study aims to comprehend architectural peculiarity of the hermitage as the one of Buddhist architectural type in Korea. Although it has not defined properly, it has been demanded the architectural respondence according to the environment of times since the introduction from other countries. Gimryong-sa temple, founded in 1635, and the hermitages are the most appropriate objects for analysis because there are many documents still remained. It is possible to find out that there are some architectural peculiarity after review of the document and the field survey about Geumseon-am(金仙庵=金仙臺), Hwajang-am(華藏庵), Daeseong-am(大成庵), Yangjin-am(養眞庵). In the late of Joseon Dynasty, the group of buddhist proceeded the economical development and the extension of authority based on the family culture. The hermitage functioned for the self-discipline, the meeting of family, the enshrinement of portraits, the memorial ceremony of family at this point. In response to that, the architectural space which had combined residence and rite became preferred such as Inbeopdang(因法堂). And a Large Ondol room called Daejungbang(大重房) was applied and Ru(樓)-Maru was added as the place for rest.

This study aims to reinterpret Jeonggwanheon(靜觀軒) in terms of its use and architectural style after restoration work through the recently discovered [Deoksugung Palace's original plan](1915). It is presupposed that the existing interpretation of Jeonggwanheon, such as its status as the banquet hall of the Imperial Empire and the place where Emperor Gojong enjoyed coffee here, was a fantasy made from the transformation after the 1930s. When it was built around 1900, Jeonggwanheon arranged small and large rooms around the corridor in the center, and the porch surrounded the three sides of the building. From 1900 to 1907, there is no remaining record telling us who did what or when something happened in Jeonggwanheon except for several portraits of Emperor Gojong and his son which were drawn in 1902. The mixed use of brickwork and wooden porch are found in many of American style houses built in Incheon and Seoul at that time. Especially, the style and decoration of wooden porch seem to be influenced by Queen Anne style in the 19th century in America.

Mean-reverting analysis refers to a way of estimating the underlining tendency after new data has evoked the variation in the equilibrium state. In this paper, we propose a new method to interpret the specular portraits of Premature Ventricular Contraction(PVC) arrhythmia by applying K-means unsupervised learning algorithm on electrocardiogram(ECG) data. Aiming at this purpose, we applied a mean-reverting model to analyse Heart Rate Variability(HRV) in terms of the modified poincare plot by considering PVC rhythm as the component of disrupting the homeostasis state. Based on our experimental tests on MIT-BIH ECG database, we can find the fact that the specular patterns portraited by K-means clustering on mean-reverting HRV data can be more clearly visible and the Euclidean metric can be used to identify the discrepancy between the normal sinus rhythm and PVC beats by the relative distance among cluster-centroids.

Most of the proceeded research of jogories in the Goryeo era are about the total clothing system of the men and women's dress and not many have studied of the developing process of the jeogories specific structures. Therefore, the purpose of this study is to figure out the origin and the alteration of a git, gil, seop and gorem which forms a jeogori after the Unified Shilla era. The range of this study os from 918 to 1392, Goryeo era and 80 pieces 7 portraits and 5 Buddhist relics were for references. This study reached the following conclusions. First, oat git, gil, seop, somae and gorem forms the Goryeo era's jogori. Second, as the length of the joegori got shorter then the past, the ryeongem also got shorter and changed to an oatgit. Third, as most of the opening side of the jeogori started to fix on the right. Forth, an extra cloth attached on the gil developes a seep that be originates in Unified Shilla when get shoter. Fifth, there were wide and very long sleeves that came all the way down to the hand, narrow sleeves and long sleeves. Sixth, Goryeo era's jeogori had ribbons and cloth buttons to fix the form instead of a belt.

This paper presents a real time algorithm for monitoring of the arrythmia of ECG signal. A real time monitoring, following by detecting a QRS complex, is the most important. Using 2-dimensional time-delay coordinates which are reconstructed by the phase portrait plotting special trajectory, we detect QRS complexes. In this study, arrythmias are detected by matching the past standard template with tile present pattern when changing abruptly In order to matching with each other, we propose modified chain coding algorithm which applies vetor table consisting of eight orthonormal code(=binary code) to the phase portraits. This algorithm using logical function increases the weight if exceeding to the threshold determinded by correlation value and the distance from a straight line(y=x). Evaluating the performance of the proposed algorithm, we use standard MIT/BIH database. The results are fellowing, 1) Improve the speed of matching template than that of cross-correlation ever has been used. 2) Because the proposed algorithm is robust to varing fiducial point, it is possible to monitor the ECG signal with irregular RR interval. 3) In spite of baseline wandering owing to the low frequency noise, monitoring performance is not reduced.

The purpose of this paper was to compare of difference between energy walking and normal walking. Subjects were selected 8 male undergraduates. The kinematic variables of a pelvis and a thorax were analysed at the take off and contact with 3d cinematography. In addition to the variables, the phase plot angle was calculated in order to definite characteristics in the phase space. The pelvic angle and angular velocity showed significant differences in the flexion/extension between two walking patterns. The pelvic angle and angular velocity were increasing when walking speed was increasing and magnitude of the variables of energy walking was larger than corresponding values for normal walking. On the other hand, the thoracic angle demonstrated significant differences in the flexion/extension and rotation between two walking patterns. The angles of energy walking were smaller in the flexion/extension and were larger in the rotation than the angle of normal walking. The kinematic characteristics of energy walking were also showed clearly significant differences in the range of motion and the relative angle of the trunk. The angle of phase plot only showed demonstrated a significant difference in the rotation at contact between the two walking patterns.
