At present, naked-eye 3D appears more and more commonly on the facades of urban buildings. It brings an incredible visual experience to the audience by simulating the natural 3D 3D space effect. At the same time, it also creates enormous commercial value for city publicity and commercial advertisements. There is much research on naked-eye 3D visual effects, but for right-angle LED screens. Right-angle LED screen's brand-new expression method that has only become popular in recent years, how to convey a realistic naked-eye 3D effect through two LED screens combined at right angles has become a problem worth exploring. To explore the whole design ideas and production process of the naked-eye 3D impact of the right-angle LED screen, this paper is a preliminary study aimed at understanding the performance principle and expression features. Before the case analysis, first, understand the standard virtual 3D space construction techniques. Combining it with the optical illusion phenomenon, according to the expression principle of the naked-eye 3D effect of the right-angle LED screen, it can be summarized into seven expressions: Shadow, Color contrast, Background structure line, Magnify object, Object out of bounds, Object floating, Fusion of picture and background. By analyzing the optical illusion phenomenon used in the case, we summarized the main performance characteristics of the naked eye 3D effect. The emergence of right-angle LED screens breaks the limitation of a single plane of optical illusion art, perfectly combines building facades with naked-eye 3D visual effects, and provides designers with a brand-new creative platform. Understanding its production principles and main expressive features can help designers enter this innovative platform better.

The purpose of this study is to estimate human sensibility quantitatively under color stimulation. We measured biological signals such as EEG, ECG, skin conductance and the number of respiration and eye blinking that were compared with color sensibilities mutually. Our result showed that red, yellow and violet color provoked active and exciting senses dominatively and blue, cyan, pink, and black color were involved in tranquil and resting emotions deeply. Our quantitative estimations of color sensibilites are useful in the design of manufactured goods and color therapy.

Man's search for beauty has been going on from prehistoric time until today, and the pursuit of beauty has been progressing, regardless of the times, as a human psychological desire. In the search for beauty, hair and make-up have been subjects of interest for a long time, but the development of designs for these two aspects are still behind compared to other areas. Therefore, this study aims to propose various new and creative hair and make-up designs and to suggest their possible development. Using existing literature, this paper studied the skin color and hair color of Koreans that had been studied in earlier papers. It also aimed to understand the hair color and hair color images that are suitable for each skin color, classify the modern hair and make-up trends into different images - natural, surrealistic, minimalist, and cyber look, and also analyze them. Actual hair and make-up were also designed based on these images. To depict the natural image, the make-up was made intentionally dark as the skin color; natural materials were used for hair decoration; brown and yellow were used for the eye shadow to express the natural and romantic image of autumn, in general. Second, in the work expressing the surrealistic image, the hair was creatively decorated with a collage of various objects; yellow, green, and red eye shadows and lip expression were used to visually achieve the surrealistic fantasy look. Thirdly, in the work expressing the minimalist image, hair style with bangs without any hair decoration was used; make-up colors were minimized as well, creating a generally simple image. Finally, for the work expressing the cyber image, metallic material decoration was used on a puff-up hair style; the cyber image was emphasized through the use of graphical elements in the make-up.

It fuses into culture of the East and the West in use of color ; colors of five direction, which had been from the Five Phase Theory in East Asia. Formative ability of color fields in a formative early Oriental Medicine history as well. Color is a very important factor and a necessary step of visible diagnosis. As a human's body is maintained and alive under the control of spirit and spirit is stored by five viscera, so spirit expresses the change of five viscera and is reflected by color. Visible diagnosis consists of spirit, appearance, Qi and color and movement. The purpose of each visible diagnosis is that we would know states of essence, Qi and spirit in patient's body. To ancient Asia people 'to see' was a kind of insight to the object as a whole. Similarily the activity of seeing the human body was the integral part of making diagnosis of a patient. This was the cause that there was suggested the discussion of the Five color theory in Oriental Medicine as a counterpart to that of the 'Goethe for Zur Farbenlehrer'. The inspection of Oriental Medicine was not a simple gazing of the eye as a sense organ, but the total insight to the internal state of the patient. For that reason, the eye－perception in early Chinese medicine was the reading the signs of the internal body which had have not the visual form but the flux of the internal life.

Purpose : This study was to investigate the change of accommodative functions by different color density and color of colored lenses. Methods : Participant had a normal NPC and no dyschromatopsia, phoria and eye disease, also had no histories of eye surgery in 31 students of university. Their accommodative functions were measured according to 50%, 80% density of the gray, blue, brown lens and non-colored lenses. Tests of accommodative functions performed include amplitude of accommodation, accommodative facility, relative accommodation, and accommodative lag. Results : The amplitude of accommodation and accommodation lag were increased when wearing the colored lens. Negative relative accommodation was more increased when wearing the colored lens than achromatic. Positive relative accommodation increased when wearing the blue color lens density by 50%. Also, accommodation facility increased when wearing the colored lens, but, as the density of the color increased, the accommodation facility was decreased. Conclusion : As since the accommodation function changes according to density of the colored lenses, working distance and environment of the wearing colored lens should be considered when selecting density and color of colored lenses.

This study was carried out to investigate a point of difference between normal and inferior Korean red ginseng (Naeback red ginseng = red ginseng with white part of clear boundary in phloem and/or xylem of ginseng body, saengnaeback red ginseng red ginseng with white part of indistinct boundary). White part with clear or indistinct boundary in center of ginseng body was observed in inferior red ginseng (naeback and saengnaeback red ginseng), and the differences in the internal color intensity was also found with naked eye. In hunter color values of normal and inferior parts of red ginseng in accordance with particle size, L value was increased with a diminishment in particle size, while a and b value were decreased. Absorbance at visible spectrum did not differ from water and 70% ethanol extract from normal and inferior parts of red ginseng, but absorbance in UV spectrum of extract from naeback part showed higher than those of normal and saengnaeback part. In comparison of intrastructure by electron microscope, the horizontal and vertical section of cortex and pith layer from normal part showed the very dense state, but small holes were found in naeback part of red ginseng by naked eye and electron microscope. The specific surface area of normal, naeback and saengnaeback part appeared 3.02, 3.33 and 6.55 ㎡/g, respectively. From above results, we consider saengnaeback red ginseng is red ginseng in the intermediate process which normal red ginseng changes to naeback red ginseng.

This study examines the effect of the structure of Intarsia and Jacquard knit on mechanical properties of knit fabrics to suggest data for knit design. Intarsia and 7 types of Color Jacquard (Floating Jacquard, Normal Jacquard, Bird's eye Jacquard, Tubular Jacquard, Ladder's back Jacquard, Blister Jacquard, and Transfer Jacquard) were used. The samples with a gauge of 14 were knitted using 100% wool 2/48's yarn by Shima Seiki SIG computer knitting machine. The Objective Hand was measured by KES-FB system and HV and THV were calculated by the formula of KN-402-KT and KN-301-winter respectively. The results showed that Intarsia and Floating Jacquard are thin, flexible and light, Bird's eye Jacquard is slick, flat and slim, Tubular Jacquard is stiff and undrapable, Ladder's back Jacquard is difficult in shearing deformation and relatively bulky, Blister Jacquard is thickest and transfer jacquard is uneven in surface contour. The selection of proper structure is important for the knit apparel production since the thickness and weight of knit determine the amount of yarn needed and consequently the production cost. The hands of Ladder's back Jacquard and Tubular Jacquard are superior to those of other structures. Intarsia and Floating Jacquard which are thin, light and flexible seem to be good structures for designs showing a body silhouette whereas, Bird's eye Jacquard, Tubular Jacquard and Blister Jacquard (which are thick, heavy, and stiff) are suitable for a boxy silhouette.

Conjunctival injection is the initial symptom of various eye diseases such as conjunctivitis, keratitis, or uveitis. The quantification of conjunctival injection may help the diagnosis and follow-up evaluation of various eye diseases. The size of the sclera is an important factor for the quantification of conjunctival injection. However, previous manual segmentation is time-consuming.Automatic segmentation is needed to extract the objective region of interest. This paper proposed a method based on the level set algorithm to segment the sclera from an anterior eye image. The initial model of the level set algorithm is calculated using the Lab color space, k-means algorithm and the geometric information. The level set algorithm was applied to the images in which the valley between the eyeball and skin was enhanced using the hessian analysis. This algorithm was tested with 52 images of the anterior eye segment. Results showed that the proposed method performs better than those with the level set algorithm using an arbitrary circle, or the region growing algorithm with color information. The proposed method for the segmentation of sclera may become an important component for the objective measurement of the conjunctival injection.

This study aims to develop knitted ware design to meet desire to express diversity in the modern fashion design so that we designed knitted ware by applying african geometric pattern and color to suggest new knitted ware design. We collect data about african texture pattern through technical books, publications, internet, and preceding research and visit and investigate the African museum. We investigate knitted Jacquard texture through preceding research and collect sample and data which is insufficient in the data source. The conclusions in this study are summarized as follows: First, African textile pattern is formulated with animism based on their religious view of art for a basis and African regards nature like animal and plant as a motive and interprets nature in the so that they can create symbolized geometric features that constitute African texture pattern. Those patterns is composed of extremely geometric figures so that they we fit to apply for color jacquad knit design. Second, color knitted jacquad can be distinguished by knitting method and status of knitting as 7 kinds of techniques such as Nomal, Bird'eye, Floating, Tubular, Ladder's back, Blister, Transfer Jacquard, and as a result of preceding research and knitting texture directly, jacquard technique makes different texture under same condition like consistent spinning rate and same crochet hook. Third, Bird'eye Jacquard used generally to make knitted ware and Ladder's back Jacquard, Tubular Jacquard used to make knitted ware light are fit to apply them to 7GG and 12GG machines. We design a cloak as a outer garment, a coat shaped like one-piece dress and a coat with hood by using Tubular Jacquard which can make thick texture and design a jacket, a skirt and a one-piece dress by using Bird'eye Jacquard. we make a light and flimsy one-piece dress by using Ladder's back Jacquard. Fourth, we apply the contrast of $4{\sim}6$ color and line and the contrast of texture and raw material to jacquard in order to emphasize texture property and visual property.
