Nonlinear dynamics of striped diffusion flames, by the diffusional-thermal instability with Lewis numbers sufficiently less than unity, is numerically investigated by examining various two-dimensional flame-structure solutions. The Lewis numbers for fuel and oxidizer are assumed to be identical and an overall single-step Arrhenius-type chemical reaction rate is employed in the model. Particular attention is focused on identifying the flame-stripe solution branches corresponding to each distinct stripe pattern and hysteresis encountered during the transition. At a Damkohler number slightly greater than the extinction Damkohler number, eight-stripe solution first emerges from one dimensional solution. The eight-stripe solution survives Damkohler numbers much smaller than the extinction Damkohler number until the transition to four-stripe solution occurs at the first forward transition Damkohler number. At the second forward transition Damkohler number, somewhat smaller than the first transition Damkohler number, the transition to two-stripe solution occurs. However, anu further transition from two-stripe solution to one-stripe solution is not always possible even if one-stripe solution can be independently accessed for particular initial conditions. The Damkohler number ranges for two-stripe and one-stripe solutions are found to be virtually identical because each stripe is an independent structure if distance between stripes is sufficiently large. By increasing the Damkohler number, the backward transition can be observed. In comparison with the forward transition Damkohler numbers, the corresponding backward transition Damkohler numbers are always much greater, thereby indicating significant hysteresis between the stripe patterns of strained diffusion flames.

This treatise deals with the profitable suit image design of middle-aged men by examining visual effects in physical design. The sample of this study is people who lives in Kwangju, the Republic of Korea and 20-50 age's men and women. And it is very variety in each population statistics factors the differences of associate design visual effect which considering the difference of sex and age group, numbers of button, a figure and material pattern. Firstly, look into the associate design visual effect by sex and button number. In men's group, the style with three buttons was the most attractive and that with two buttons was the least attractive. In 50's group, the style with two buttons was the least attractive and those with 1.3 and 4 buttons were a little attractive. Secondly, in the difference of associate design with sex and shape, men's group was considered that standard type was the most attractive shape, women's group was thought that lean and standard types were the most attractive shape. So we can know that the attractive shape is different with sex. In the difference of association design with age and shape, 20's considered that standard type was the most modernistic and fat type was the least modernistic. 30's considered that lean type was the most modernistic and 50's thought that fat type and standard type were the most modernistic. Thirdly, see the sex and material pattern. In familarity, men's group considered that stripe pattern was more familiar than checks and plain patterns. And they considered that striped pattern and plain was more manly than checks. In sex and material pattern, 20's thought that plain was the most attractive, stripe was the next, and checks was not attractive. 40's estimated that plain and stripe were more attractive than checks. 50's judged that stripe was the most attractive material. Thus. the attraction is different with ages and material patterns.

본 논문에서는 물체위로 투사된 line stripe으로부터 물체의 표면 정보를 추출하기 위해 2-D Grip paper를 이용해 캘리브레이션하는 방법이 제안되었다. 카메라의 이미지평면과 카메라의 가시범위에 있는 3차원 실세계간의 Projective Tranformation과정에서는 목표물과 이미지 평면사이의 거리나 각도 등이 정보를 실제로 측정해서 알고 있어야만 카메라와 실세계간의 캘리브레이션을 수행할 수 있다. 그러나 이미 크기나 거리를 알고 있는 Grid paper를 이용하면 카메라의 파라미터들에 대한 추정이나 카메라와 실세계간의 측정을 하지 않고서도 목표물위로 투사된 line stripe에 대한 정보를 얻을 수 있고 이를 이용해 물체의 표면에 대한 정보를 얻을 수 있다. 이미 지평면에 투영된 격자패턴에서 구한 교차점들의 위치를 이용해 실제 위치를 찾아낸다. 실제로 레이져스캐너를 이용해 물체위로 line stripe을 투사한 후, 위에서 제시한 방법을 통해 3차원 정보를 구하는 실험결과는 양호하였다.

This study is purpose to trace a genealogy of Rainbow stripe in 30 ethnic costumes in East Asia. And with through comparative views between Korean and the other minority that is shown a bilateral relation of rainbow stripe in their costume, we make sure the unique character of rainbow stripe in Korean traditional costume. The stripe in the costumes was generally used on sleeves with 3~6 patches. There were 10 types of methods for making the stripe including sewing. Weaving and sewing with trimming was also frequently used either and the stripe by weaving with multicolored yarns were mostly found in the southern region of china. Black, blue and red were frequently used in the costume as a main color that was contrasted with rainbow stripe and especially, black was mostly used. Korean preferred bright colors as a main color. Contents of the genealogy of the multicolored stripe in ethnic costume in East Asia are followed. The 28 ethnic groups who used the stripe in their dress except Korean, the Mans, Mongo people and Tibetan were located in the southern region of East Asia. And the other ethnic groups distributed in the northwest and northeast region of East Asia. The distribution of the rainbow stripe in the costume could be grouped into two sections: the southern region people and Korean-the Mongol people-the Tus- the Zangs group. And the latter group was shown strong relation with the culture of Korean's rainbow stripe costume. 11 ethnic peoples including Korean, the Vis, the Miaos, the Tus, the Mongol people, the Chaoxians, the Zangs, the Lahus, the Jinuos, the Hanis, the Luobas and the Dulongs, were saliently used the stripe in their costume. The stripe in Japanese costume was judged that was not a kind of the rainbow stripe was shown the other ethnic groups, was a color arrangement by layered dress or geometrical pattern. From above, we could recap a particular characteristic of the rainbow stripe in Korean traditional costume. Many colors were used in the stripe and bodies than the other ethnic people and the color was bright. In many cases, a color of patch at the point of armhole was red and Black color was not used in the stripe. The width of patch was a relatively narrow and regular. It has shown that the rainbow stripe in Korean traditional costume was organized independently.

One of the main problems in 3D shape measuring systems that use the triangulation of line-shaped laser light is precise center line detection of line-shaped laser stripe. The intensity of a line-shaped laser light stripe on the CCD image varies following to the reflection angles, colors and shapes of objects. In this paper, a new center line detection algorithm to compensate the local intensity variation on a line-shaped laser light stripe is proposed. The 3-D surface shape measuring system using the proposed center line detection algorithm can measure 3-D surface shape with enhanced measurement resolution by using the dynamic shape reconstruction with adaptive pattern clustering of the line-shaped laser light. This proposed 3-D shape measuring system can be easily applied to practical situations of measuring 3-D surface by virtue of high speed measurement and compact hardware compositions.

The objectives of this study were to classify bedclothes purchase motives and to examine how bedclothes purchase mo-tives and design preferences very accord-ing to age and income. Samples were 217 housewives residing in metropolitan area. Questionnaire included 17 Likert type items of bedclothes pur-chase motive measure 12 items of color preference 7 items of pattern (floral geo-metric abstract stripe plaid polka dot, and paisley pattern). The results of the study were as fol-lows. 1. 5 factors of bedclothes purchase mo-tives were derived by factor analysis ; F .1 'design': F 2. "brand' ; F.3. 'deficiency'; F. 4. 'fabric' F.5. 'economical reason' 2. Subjects perceived design and utility area to be important motives for bed-clothes purchase. 3. Cholor preference of bedclothes was in the order of white pale blue pale green and pale orange. Pattern preference was in the order of stripe plaid solid color floral and polka dot pattern. The combi-nation of patterned fabric and solid color fabric was liked better than the combina-tion of analogic color and the combination of contrasting color. 4. The women in their 20's liked navy blue red stripe plaid pattern and solied color better than 30's and 40's . 40's liked abstract and paisley pattern better then 20's and 30's 5. Low income group lied navy blue and solid color fabric more than the mid-dle and high income group and liked ab-stract pattern less than the middle and high income group. 6. Women in their 20's perceived design to be important motive more than 30's and 40's. 30's perceived brand to be im-portant motive than 20's and 40's 7. High income group perceived design to be important motive more than the middle and low income group. Low in-come group perceived brand and fabric to be less important motives than the middle and high income group, The present findings provide that age and income had a significant effect on bedclothes purchase motives and design preferences of houesewives. The results that white color and the combination of patterned fabric and solid color fabric were liked best indicated that women prefered clean image and chacteristics de-sign of bdeclothes.

This study aims to characterize the effect of different combinations of chromatic-achromatic colors and 1:2:3 area-ratio variation of stripe necktie, and gender on the image of male wearer. The experimental materials developed for this study are a set of stimuli and response scales. The stimuli consist of 84 color pictures manipulated with every combination of 12 different colors and 7 different area-ratio. The 7-point scale designed for visual evaluation of image formation included 26 bipolar adjectives. The subjects were 2016 undergraduate students in Gyeongnam, Seoul, Busan, and Daegu areas. The results of this study were as follows. The analyses of images of male wearer in terms of combinations of chromatic-achromatic colors and I :2:3 area-ratio variation of oblique stripe necktie reveal that the concerned factors are of five characteristic dimensions of youth-activity, ability, attractiveness, appeal, and warmness. In addition, it has been found that individual images of male wearer are affected by observer's gender as well as combinations of chromatic-achromatic colors and 1:2:3 area-ratio variation of stripe neckties and that those images vary with every combination of each factor. The study results are highly expected to be used as useful sources in developing necktie designs.
