Objective : Neuroimaging data are of paramount importance in making correct diagnosis. We herein evaluate the clinical usefulness of image transfer using cellular phones to facilitate neurological diagnosis and decision-making. Methods : Selected images from CT, MRI scans, and plain films obtained from 50 neurosurgical patients were transferred by cellular phones. A cellular phone with a built-in 1,300,000-pixel digital camera was used to capture and send the images. A cellular phone with a 262,000 color thin-film transistor liquid crystal display was used to receive the images. Communication between both cellular phones was operated by the same wireless protocol and the same wireless internet service. We compared the concordance of diagnoses and treatment plans between a house staff who could review full-scale original films and a consultant who could only review transferred images. These finding were later analyzed by a third observer. Results : The mean time of complete transfer was $2{\sim}3\;minutes$. The quality of all images received was good enough to make precise diagnosis and to select treatment options. Transferred images were helpful in making correct diagnosis and decision making in 49/50 [98%] cases. Discordant result was caused in one patient by improper selection of images by the house staff. Conclusion : The cellular phone system was useful for image transfer and delivery patient's information, leading to earlier diagnosis and initiation of treatment. This usefulness was due to sufficient resolution of the built-in camera and the TFT-LCD, the user-friendly features of the devices, and their low cost.

Donor-$\pi$-acceptor (D-$\pi$-A) type chromophore-based polymers were newly synthesized. These polymers exhibited absorption peak due to intramolecular charge transfer (ICT) in a visible range as well as absorption peak due to carbonyl group in both solution and film state by measuring UV visible spectra. The addition of $Eu^{3+}$ ion into the polymers induced red-shift in absorption due to ICT and the color changes from yellow to red in the solution and film were observed by naked eyes. The contents of crosslinking agent influenced the features and solubility of the polymers. In addition, the contents of crosslinking agent and the $Eu^{3+}$ ion addition improved film-forming ability.

The usual method of generating an image for a multiview display system requires acquiring a color image and depth information of a reference camera. Then, intermediate images, generated using DIBR method, will be captured at a number of different viewpoints and composed to construct an multiview image. When such intermediate views are generated, several holes would be shown because some hidden parts are shown when the screenshot is taken at different angle. Previous research tried to solve this problem by creating a new hole-filling algorithm or enhancing the depth information. This paper describes a new method of enhancing the intermediate view images by applying the Ball Pivoting algorithm, which constructs meshes from a point cloud. When the new method is applied to the Microsoft's "Ballet" and "Break Dancer" data sets, PSNR comparison shows that about 0.18~1.19 increasement. This paper will explaing the new algorithm and the experiment method and results.

Korean Chinese, immigrants to China, have developed their own traditional costume culture. This paper aims to analyze the traditional costume culture of the Korean Chinese and to provide data for posterity. The research methods are literature research, survey research, and analysis research. The results are as follows: According to the changes over generations, the top of women's Hanbok has changed in length as has the jeogori (jacket), the git (collar), and the gooreum (breast-tie). The width of the git, dong-jeong (thin white cloth-covered paper collar of Hanbok), the sleeve, and gooreum have also changed. The git and the barae (the curve part of the sleeve) have changed from straight patterns to curves. The skirt had changed in wrinkles arrangement, length, and silhouette. The men's Hanbok jeogori and sleeves were lengthened; the pants became wider and were lengthened, and the collar also became curved. The vest has not changed and the du-ru-ma-gi (coat) that once disappeared is being worn again; the bae-ja (vest) and magoja (over-jacket) are worn frequently in modern times. The garments mainly used natural fiber until the development of synthetic fibers, but the treand has been the use of luxurious natural fibers in modern times. The initial color pattern was achromatic, but that changed with the appearance of synthetic fibers, and nowadays it is mainly the garmetnt can display a variety of colors. In addition, hairstyles and shoes have been eveolved from traditional to modern styles.

The purpose of this study was to identify Web accessibility issues of healthcare websites of the Korean government and public agencies by evaluating these websites' accessibility in accordance with the Korean Web Contents Accessibility Guideline. This study conducted both automated and expert testing to assess the accessibility of a total of 27 health-related websites. The results of the assessment which was conducted in two stages indicated that institutions such as the National Hospital and National Rehabilitation Center demonstrated almost no Web accessibility error. In addition, the Korea Health Insurance Review and Assessment Service, the Ministry of Health and Welfare, the Health Services Agency, the Ministry of Food and Drug Safety, and the Korea Medical Dispute Mediation and Arbitration Agency attained very high web accessibility. However, the results of an expert evaluation highlighted that there were considerable errors in providing appropriate alternative text, which was not found in the automated test, and the color contrast of the text content did not comply with Web accessibility standard. Therefore, these websites did not support web accessibility for the sight-impaired. Furthermore, the present study found that it was difficult to deliver accurate information to users due to errors in the default language display and markup, and also, issues of skipping repeated content, content linearization, and compliance with keyboard use were considered as challenges that might arise for people with sight, cognitive and mobility impairments with respect to Web accessibility. It is the first study that evaluated accessibility of healthcare websites of the Korean government and public agencies based on the Korean Web Contents Accessibility Guideline. The present study made a contribution to research on Web accessibility by conducting expert testing, which provided a more complete assessment that identified the degree and specific issues of accessibility errors when compared to automated testing.

Up to now, image of femme fatale has undergone constant transformation to be inherited and developed through various genres of movies. With few exceptions such cases have represented sensuality of women by costumes with the most distinctive and exaggerated sexuality. Temptresses in movies are mostly drawn as extravagant and gorgeous one or a gloomy and dreary woman. Such an image is reinforced with make-up, hair style, accessories, attitude and manner of talking. The movie 'Chicago' is a musical film that crosses the boundaries of reality and fantasy with dancing and singing. Its lighting, stage setting, powerful and sexy dancing augmented already exaggerated and sensual costumes. Following is the analysis of costumes for two heroines as images of femme fatale. Strong contrast of color among black, red and blue on see-through & stickingly tight body suit signifies liberal mind and arrogant charisma of Velma. The contrast, haughty gestures, cropped black hair and thick makeups represent sex appeal, aggressive image, and fearlessly determined character of femme fatale. Roxie wears decent dresses in front of public and gorgeous stage costume in fantasy to convey two images of bad girl and angel. Her body suit, showing off lustering materials and dazzling bead decoration, is rather loose but still displays her bodyline to emphasize sexiness for representation of desire in fantasy. Chastity and innocence are implied with the decency of dresses in reality. They were specially chosen to draw public sympathy and indicate cunning disguise of Roxy who desperately wants to realize her desire. These dauntless costumes, which sufficiently express inside aspirations of Velma and Roxie later denote open and realistic social yearning rather than fatal desire hidden behind sensual beauty. It doesn't exist as imperfect, unrealistic and socially disdainful ambition as the image of femme fatale of paintings and movies did before in history. Femme fatale is expressed with deep cleavage, silk dresses that explicitly display bodyline, sexiness of mesh stockings with garter belts. All of these won't be utilized as a negative tool to seduce and destroy someone anymore but rather, they should represent rightful and fair nature of humans such as men's curiosity who secretly steal a look at them or female sexuality that women spontaneously want to show off.

The study aims to suggest the direction of improvement in presenting the exhibition space by examining the current status quo of children's science exhibitions in order to enhance the educational effectiveness Children's Science Museum. For this purpose, the children's science museum exhibition and exhibition space were categorized into three themes largely according to the exhibition contents, and an analysis framework was developed to analyze exhibition media and exhibition space. For the research subjects, we selected 7 exhibition halls targeted at children in Korea, collected data via video-taping, and analyzed based on the framework of analysis. When analyzing the display situation in which the exhibits have the contents of 'body', 'peripheral things', and 'natural phenomena', we found that the exhibits are composed of too difficult contents to understand, which do not fit the children's developmental level, and the major media used are observational and explaining media. Additionally, concerning the exhibition space, there is a tendency to rely on the installation elements and color effect. It is also difficult to deduce the contents of the exhibits and the entire story. We suggest that the entire exhibition planning be carefully made from the beginning to improve the current status and enhance the educational effectiveness of the Children's Science Museum with the help of experts.

This research was conducted to see the impact of brightness, polarity, and hue diference on legibility and emotional effcts of the word. In the experiment 1, stimuli with three levels of brightness difference and two-typed polarity were used. The results showed that legibility, aesthetics, and preference increased with increasing brightness difference. In the experiment 2, the same stimuli if experiment 1 included four hues: red, green, blue, yellow. As a result, the effects of brightness and polarity and the interaction effect of brightness and polarity on legibility were significant. Also, the effects of brightness, polarity, and hue and the interaction effect of brightness and hue on aesthetics and preference were significant. These results showed that legibility, aesthetics, and preference increased with increasing brightness difference of word and background and positive polarity was better than negative. Aesthetics and preference rating increased according to the following order: red, blue, green, yellow. In addition, the interaction effect of brightness and polarity on legibility was because reaction time of negative polarity was longer than positive at the small brightness difference condition. The interaction effect of brightness and hue on aesthetics and preference ws because the aesthetics rating of hue at the large brightness difference condition had significant difference compared with small brightness difference. In the experiment 3, participants rated text designs and simple color stimuli with 18 emotional adjectives to see the similarity of their emotion. The conclusion was that to reflect the subjective feelings of a rotor on the text design, it would be appropriate to use the rotor on background of the text design.

In this study, we are trying to verify humidity control capability of the exhibition environment of cultural property by measuring adsorption and desorption performance, the control ability of harmful substances by the adsorption experiments of harmful gases. In the experiment of adsorption and desorption performance, in the low humidity area, Artsorb desorbed overwhelmingly more than activated carbon whereas activated carbon absorbed more. Adsorption speed was faster slightly in Artsorb absorption speed was similar in both. In the middle humidity area, absorption by artsorb was slightly more and desorption was similar in both so characteristic of Artsorb didn't appear. Also, Adsorption speed was faster in activated carbon but in the process of desorption, the speed of Artsorb was faster. In adsorption experiment of harmful substances, the concentration in the environment with activated carbon was lower than one with Artsorb, but the difference appeared small. And as a result of observation of the difference in concentration due to adsorption of harmful gas by the change in the metal specimen, the most change was shown in lead specimen and the color difference between the lead specimens of the activated carbon and Artsorb appeared greatly.
