Oral cancer surgery typically consists of resection of lesion, neck dissection and reconstruction, and it has an impact on the position of hyoid bone. Therefore, morphological change of airway can occur since the geometric parameter of airway is correlated with the hyoid bone. Airflow is affected by geometry of the airway. In this study, flow characteristics were compared between pre- and post-surgery models by both particle image velocimetry (PIV) and numerical simulation. 3D model of upper airway was reconstructed based on CT data. Velocity is accelerated by the reduced channel area, and vortex and recirculation region are observed in pre- and post-surgery models. For the post-surgery model, high pressure distribution is developed by significantly decreased hydraulic diameter, and the longitudinal flow stream is also interrupted.

We propose statistical methods for evaluating the efficiency of CAPTCHA. Most people unfairly assumed that machines are not capable at reading precisely. This fact leads to the invention of CAPTCHA, a distorted word or short phase, which is designed to thwart computers and separate human from machines. However, advances in image recognition technologies mean that machines are constantly getting better at recognizing CAPTCHA. This forces CAPTCHA designers to design even more difficult CAPTCHAs to prevent their systems from being gamed by malicious bots. However, this arm race has an unintended side effect on the common users. Many CAPTCHAs are now so hard that many people are unable to read them. This obviously conflicts with the original purpose that CAPTCHA was invented in the first place. Our analysis shows that some CAPTCHAs are more users friendly. In particular, Yahoo-style CAPTCHA is the most friendliness. This suggests that a good CAPTCHA could be a simple text with some distortion that prevents machines from correctly segmenting characters.

In this paper we present a system that enables the user to interact with large display system even without touching the screen. With two infrared sensitive cameras mounted on the bottom left and bottom right of the display system pointing upwards, the user fingertip position on the selected region of interest of each camera view is found using vertical intensity profile of the background subtracted image. The position of the finger in two images of left and right camera is mapped to the display screen coordinate by using pre-determined matrices, which are calculated by interpolating samples of user finger position on the images taken by pointing finger over some known coordinate position of the display system. The screen is then manipulated according to the calculated position and depth of the fingertip with respect to the display system. Experimental results demonstrate an efficient, robust and stable human computer interaction.

In human history, scarf has acted not only as a protection for body but also as a symbolization of class. Today, scarf has become a whole field in fashion and an important accessory to express individuality in fashion. Hence, like other fashion item, it is very important to develop exclusive design for scarf by analyzing the current fashion trend. In this research, we have designed a scarf textile, accordance with the contemporary design trend, applying the floral pattern, designed by William Morris who was an artist considered as the founder of the 1800s arts and crafts movement. We selected four trend themes, "Salon de Archives", "Eco Tech", "Profound Nature", and "Neo Aristo" for the design of 2007/2008 Fall/Winter. The flower motifs in Pimpernel Wallpaper, Honeysuckle textile design, Acanthus Wallpaper, Garden tulip wallpaper, Evenlode printed cotton, Trellis Wallpaper, and Chrysanthemum Wallpaper, by William Morris who expressed an image of environment friendly and nature reversion, applied to develop new creative scarf through design after modifying and rearranging these flower patterns. After the pattern was drawn by hand, adjusting of color and repeating of the design was done with DTP (Digital Textile Printing). Through this research, the researchers hopes to be of assistance to the development of national scarf brand design, and to the recapturing of textile industry that once played a important role in Koreans economic development.

본 연구의 목적은 의미변별법을 이용한 사서교사의 자아상 검사 도구를 개발하고, 사서교사의 자아상을 측정하여 개인별 특성과 자아상 간의 상관관계를 분석하는 것이다. 사서교사의 자아상 측정 결과 사서교사는 스스로를 '친절하고 계획적이며 섬세하고 협조적일 뿐만 아니라 분별력을 갖춘 사람'으로 인식하고 있는 것으로 나타났다. 한편으로는 '불공평하고 초라하며 영향력이 없을 뿐만 아니라 무시당하고 비활동적'이라는 부정적인 자아상을 가지고 있는 것으로 나타났다. 사서교사의 배경 변인 중에서는 교육경력이 평가영역에 유의미한 영향을 끼치는 것으로 나타났다. 이러한 결과는 선배 사서교사의 조언자 내지는 리더로서의 역할 수행이 매우 중요함을 보여준다. 선배 사서교사와 후배 사서교사의 교류와 협력을 활성화하기 위해서는 한국도서관협회나 한국학교도서관협의회의 중재자로서의 역할이 강화되어야 할 것으로 보인다. 또한 사서교사 배치를 의무화하여 직업적 안정감과 성취감을 가질 수 있도록 하고, 학교도서관의 인적자원 간 명확한 역할 구분을 통해서 전문성을 인정할 필요가 있다.

This project purpose to develop a "custom patient gown" can satisfy with functional and aesthetic aspects for improving the problems of the existing children's patient gown that no unified image and discomfort in cooperation with the Public Design Development office as part of the citizen-friendly design improvement projects which one of the public politicizes of Seoul. The following are the results of design process for children's patient gown applying the universal design. First, the children's patient gown of the shape were classified into patient gown, rehabilitative gown and special gown and based on human-centered design to pursue the custom patient gown. Second, the color used pastel shades part of the Seoul colors and focused on emotions with color therapy theory. It was emphasized the aesthetic aspect by arranged the colors which harmonized with the main colors, also classified the wards and sizes. Third, for the functional materials of patient gowns was used the washable fabric and tender processing. Fourth, the accessories were matched the unified image and colors are suitable for the hospital environment such as bibs, aprons, and bedding. Fifth, Haechi, the symbol of Seoul was used as the logo. The Haechi logo and emotional message were applied to patient gowns to enhance the communication efficiency between patients and their guardians. As described above, the custom patient gowns for children's hospital will have significant ripple effects when they are expanded to national, public and private children's hospital. Such a qualitative change will pursue the respect and value of human by expanding the areas of public design for adults, the weak and the old-age society in future.

This study considers types of expression and examines aesthetic characteristics through analyzing designs (such as the Coca-Cola contour bottle as fashion) which has actively progressed in the collaboration of fashion designers and fashion brands. The conclusions of this study are as follows. The types of fashion expression on the Coca-Cola contour bottle are a presentation of diverse fashion images through a digital print expression that allow people-friendly images to be three-dimensional (or by adding a formative element) and the use of accessories or clothes. The symbolism characteristic were first indicated for the aesthetic characteristics on the Coca-Cola contour bottle. Symbolism is indicated through the identification of an implicit meaning towards a specific object. The symbolism of fashion was highlighted by designing the Coca-Cola's contour bottle with a typical material and pattern pursued by fashion designers and fashion brands. Second, the characteristic of playfulness was presented to expresses the instinctive desire in human nature for pleasure. The expression of visual playfulness is emphasized through the combination of item and image or by changing and re-analyzing a form through refuting stereotypes. Third, the characteristic of femininity was shown to express beauty in external image or a woman's delicate and soft inner propensity. Femininity was created by presenting a sensual femininity that recognized the voluminous curve silhouette of the Coca-Cola bottle such as a sexy female body or through the combination of a women's inner beauty with the sensory image of the object.

The purpose of this study is to research on concept, consisting factors, and specialties of theme park' character costumes to understand better about character costumes as well as to establish fundamental research data. The characteristics of character costumes in the theme park are as follows. First, theme park' character costumes are personified so that visitors may feel friendly and have emotional communication with them. Specially, costume that anthropomorphize an animal(85.3%) and silhouette of lozenge style(86.8%) dominated the highest weight. Animal figures are walking upright and wearing human's clothes. They communicate with visitors using mime actions. Second, various types of body proportion is applied to highlight the characteristics of character costume. Most character costumes are applied with unrealistic body proportion. This unrealistic body proportion give abnormal image and looks funny. The important factor is size of their head. Especially, 3.5 body proportion(78.9%) is general. Third, simplification, exaggeration, shrinkage, and modification are other factors. Simplification is applied differently by parts. Pocket, collar details are simplified to clarify the character's image. More simplification can lead to ommission. For their head, peculiar parts look stand out but other parts are simplified to stress their characteristics. Exaggeration is used with shrinkage to give strong impression to visitors. Forms are broken intentionally and they are modified. They look impressive because they are not harmonized. It is unexpected image and induces humor and familiar feelings. Matter of stylization includes exaggeration, shrinkage, modification and movement of actors that have tangible factor of character costume.
