  • The proximal isovelocity surface area (PISA) method is an effective way of measuring the regurgitant blood flow rate in the mitral valve. This method defines the modelling required to describe the geometry of the isotach of the PISA. In the normal PISA flow model, the flow rate is calculated assuming that the surface of the isotach is either hemispherical or non-hemispherical numerically. However, this paper evaluated the estimate flow rate using a direct surface subdivision flow model based on the height field after isotach extraction using a region-based scheme. To validate the proposed method, the various PISA flow models were compared using pusatile color Doppler images with flow rates ranging from $30\;cm^3/sec\;to\;60\;cm^3/sec$ flow rate. Whereas the hemispherical flow model had a mean value of $29\;cm^3/sec$ and underestimated the measured flow rate by 35%, the proposed model and non-hemispherical model produced a c;ame mean value of $45\;cm^3/sec$, moreover, both flow models produced a similar pulsatile flow rate.

  • Previous hardware devices to capture human motion have many limitations; expensive equipment, complexity of manipulation or constraints of human motion. In order to overcome these problems, real-time motion capture algorithms based on computer vision have been actively proposed. This paper presents an efficient analysis method of multiple view images for real-time motion capture. First, we detect the skin color regions of human being, and then correct the image coordinates of the regions by using camera calibration and epipolar geometry. Finally, we track the human body part and capture human motion using kalman filter. Experimental results show that the proposed algorithm can estimate a precise position of the human body.

  • In this paper we propose a real-time method to estimate a pointing region from two camera images. In general, a pointing target exists in the face direction when a human points to something. Therefore, we regard the direction of pointing as the straight line that connects the face position with the fingertip position. First, the method extracts two points in the face and the fingertips region by using detecting the skin color of human being. And we used the 3D geometric information to obtain a pointing detection and its region. In order to evaluate the performance, we have build up an ICIGS(Interactive Cinema Information Guiding System) with two camera and a beam project.

  • The purpose of this study was to illuminate eroticism represented din modern fashion. Art based on sex is very important like all of the other cultural values. But we feel that erotic art, neglected, suppressed , and persecuted for centuries, has an important contribution to make to the understanding of art, the social history of mankind, and human happiness and progress. It is our deep personal conviction that erotic art serves important social and therapeutic functions. Erotic art expresses the demand for sexual freedom-a freedom vital to individual happiness and mental well-being, And sexual freedom, in turn, cannot exist without a high degree of political and economic freedom as well. In that sense , erotic art came a truly revolutionaly message ; it demands no less than extension of freedom , not only in the sexual are, but in every sphere of social life. What is eroticism \ulcorner Eroticism must be distinguished from a mere animal reproduction . Eroticism is deeply rooted in the cultural tradition of myth, religion , customes and art. It also has a close relationship with psychological activities of our life. Eroticism is a kind of psychological revolution in the development of human civilization. Eroticism is related to different kinds of art, which express internal spirit of human especially Surrealism. Surrealism is above all a movement of the conquest and deepening of the unconscious. The exploitation of Freud's discoveries opended a new, practically unlimited path for artistic studies to Surrealism . Especially all theory of mental psychoanalysis a affected artists greatly in western art, Freud was appraised highly on his achievements by art critics in art history on his achievements by art critics in art history. As far as erotic subject matter was concerned, Surrealism provided a means of presentig it. Pop Art is not actually a movement , born at a specific time and place, nor is it an easy concept to define. The term first appeared in Great Britain during the fifties, when it referred, particularly in the decorative arts, to an inclination to go back and imitate the stereotyped images of the mass media : film, advertising , cartoons, and other popular consumer products. The eroticism expressed in Pop Art calls the modern's attentions to their devastated minds, taking advantage of the commercialized sex. Fashion has developed constantly reflecting the spiritual aspiration and social and cultural phenomona of man , and artistic steam. Eroticism in fashion is the style which expresses the internal meanings of sexuality through the texture, color, pattern , silhouette etc.

  • This study examines international tourists 'perceived images and service quality of Korean foods. A survey was conducted to international tourists(Chinese, Japanese, American) visiting Korea. The results of study show that there is a significant difference in several attributes of Korean traditional foods as perceived by international tourists along their nationality. Particularly, American tourists tend to highly evaluate Korean foods as ones good for health. The perceived attractiveness of Korean foods in terms of color and shape is higher for Chinese and Americans than Japanese. A distinct difference is also found in the importance and performance attributes of perceived quality of Korean foods by the nationality of tourists. The results of IPA for the perceived quality of Korean traditional foods show that the restaurant facility and atmosphere are identified as the ones that need to be improved across all the tourists.

  • This paper presents an approach for detecting and measuring human skin pigmentation. In the proposed scheme, we extract a skin area by a GMM-EM clustering based skin color model that is estimated from the statistical analysis of training images and remove tiny noises through the morphology processing. A skin area is decomposed into two components of hemoglobin and melanin by an independent component analysis (ICA) algorithm. Then, we calculate the intensities of hemoglobin and melanin by using the projection transformed block coefficient and determine the existence of skin pigmentation according to the global and local distribution of two intensities. Furthermore, we measure the area and density of the detected skin pigmentation. Experimental results verified that our scheme can both detect the skin pigmentation and measure the quantity of that and also our scheme takes less time because of the location histogram.

  • Purpose: The purpose of this study was to design a mobile-application of a cognitive training program for people who have chemo-related cognitive complaints. Methods: The program was developed based on the network-based instructional system design proposed by Jung. The program consisted of several tasks centered on four cognitive domains: learning, memory, working memory, and attention. For memory learning, a target-image and all its elements (color, position, and number) were presented on the screen that had to be recognized among a number of distractor-figures. In working memory training, the previous learned target-figure according to the level of difficulty had to be remembered among many different figures. In attention training named "Find the same figure," two identical symbols in a grid-pattern filled with different images were presented on the screen, and these had to be simultaneously touched. In attention training named "Find the different figure," a different symbol in a grid pattern filled with same figures had to be selected. This program was developed to train for a minimum of 20 min/day, four days/week for six weeks. Results: This cognitive training revealed statistically significant improvement in subjective cognitive impairments (t=3.88, p=.006) at six weeks in eight cancer survivors. Conclusion: This cognitive training program is expected to offer individualized training opportunities for improving cognitive function and further research is needed to test the effect in various settings.

  • As a plan for establishing Korea's cultural identity and its competitive edge in the world market and for enhancing Korea's cultural status, creative and unique high value-added cultural products need to be developed utilizing our inherent cultural assets. Accordingly, this study focused on the development of the design of fashion cultural products that utilize the convergence of Hangeul our peculiar font style and Korea's cultural heritage, which is registered as part of UNESCO's World Heritage. A design method was devised that converges archetypal images of cultural property with the unique Hangeul font in a way that targets Korea's symbolic architectures. The symbolic architecture includes Korea's world-heritage pagoda architecture, such as Seokgatap pagoda and Dabotap pagoda at Bulguksa temple. It also included the architecture of royal palace, such as Injeongjeon hall at Changdeokgung palace. Finally, it also included the architecture of the fortress wall, such as Paldalmun gate in Hwaseong fortress. Thus, by developing cultural assets made from a convergence between architecture and the Hangeul font as a consumer-product image that has universality, the possibility of cultural products was pursued by applying color planning after an analysis that involved extracting the compositional colors of the flags of the world. This research and approach will lead to opportunities for further progress for Korea's cultural products in the global market as a results of additional recognition for their value, excellence, and universal appeal.

  • This study intended to analyze the transition of design of Korean soccer player's uniform according to development of the society and changes in formative elements, and examine features inside them by considering designs of soccer player's uniform by ages ranging from the introduction of soccer up to now. Results of the study are summed up below. First, as a result of analyzing designs of soccer player's uniforms from 1920 to 2002 Korea-Japan WorldCup based on formative elements of the style of dress. \circled1 it is shown that basic shape has been kept but changes in only color. cutting, trimming, logo and symbol have existed. \circled2 Colors of the uniforms have been different according to ages but red, blue and white colors have been used most and sometimes black was employed. so it is known that colors in the Korean national emblem have been all used. \circled3 In the beginning of the uniform there was a limitation in its design due to absence of functional materials but now highly-sensitive textile products and highly-functional textile materials guaranteeing optimal condition and highest activity of a soccer player have been utilized in various ways. \circled4 It is known that symbols modelling the image of Korea have been used in diverse ways but effected much by directions toward images pursued by designers of sponsors. Second, the meanings represented by designs of the uniforms are classified into a degree of symbolizing Korea, tradition, superiority and dynamics. That is to say, \circled1as colors and symbols coming from the emblem have been used in the uniforms. they have symbolized one nation and possessed the meaning representing even Korean national spirit. \circled2As traditional colouring and symbols have been used in the uniforms, they have shown the Korean sense of a beauty. \circled3 Colors, tones and designs overwhelming the mood of play have been used in the uniforms, so that they have played a role in making players of other team flinch mentally and making Korean players gain an advantage over them. \circled4 Thanks to strong symbols or comparative effects of colors. they have shown the dynamics representing power and energy.

  • The purpose of this study is to research the characteristics and types applied to Korean and foreign luggage brands, and then develop pattern designs for the luggage by applying Korean cultural contents that meet the various fashion needs of travel goods. To select the Korean and foreign luggage brands, a web search was utilized by inputting the keyword, 'luggage brand'. The results, which were extracted from 200 web documents, produced 27 Korean brands and 29 foreign brands that met the requirements. For the data analysis, images and contents were collected through luggage brand websites, and then 927 pattern designs were extracted. The results were as follows. First, characters, figures, animals, and plants were commonly used for the pattern design motifs applied to Korean and foreign luggage. A notable trend was that these motifs were expressed in a stylistic way with a graphic touch. Also, a singular point was formed from the luggage overall, and regularly repeated patterns were very common as well. Secondly, pattern designs for luggage were developed through the application of 'Hangul', 'Hanbok', and 'Hanok'. Nine kinds of patterns were designed via the phases of change into a vector image and color adjustments, and were simulated in luggage design. Adobe Photoshop CS 7.0, and Adobe Illustrator CS 5.0 programs were used for the pattern designs and simulations. This study is meaningful in that it suggested pattern designs for different kinds of luggage in the motifs of Korean cultural contents. It can be used as a useful reference, as we are in a time period where travel goods have become individualized, advanced, and fashionable, as well as laying stress on original design based on cultural interpretation.
