The main purpose of this study was to explore the development of knowledge about the appearance-reality distinction and the perspective-taking ability and to examine its relation. The subjects were 104 children, 13 boys and 13 girls each at the age of 3, 4, 5, and 6. The performance of four age groups were compared on illusion appearance-reality, color appearance-reality, perceptual perspective-taking, and cognitive perspective-taking tasks. The data were collected by individual testing and analyzed by the two-way ANOVA with repeated measures, one-way ANOVA and Pearson Correlation Coefficients. The major results were as follows. 1. In children's understanding of the appearance-reality distinction, significant differences were found between 3-year-olds and 4-year-olds, and 5-year-olds and 6-year-olds. While between 4-year-olds and 5-year-olds showed no such differences. Besides, gender did not affect the children's understanding of the appearance-reality distinction. 2. There was significant difference in performance according to the type of tasks. That is 3-year-olds perform better illusion appearance-reality distintion than color appearance- reality distintion, while 4, 5, 6 year old children's performance of color appearance-reality and illusion appearance-reality distinction showed no difference. 3. In children's ability of perceptual perspective-taking, significant difference was found between 3, 4, 5-year-olds and 6-year-old children. And in ability of cognitive and perspective-taking, significant difference was found between 3, 4-year-olds and 6-year-old children. Besides, gender did not affect the children's perceptual and cognitive perspective-taking. 4. The color appearance-reality distinction and perceptual perspective-taking showed significant correlation. That is, the children of high grade for perceptual perspective-taking were better understanding of color appearance-reality distinction.

The metallicity distribution of globular clusters (GCs) provides a crucial clue for the star formation history of their host galaxy. With the assumption that GCs are generally old, GC colors have been used as a proxy for GC metallicities. Bimodal color distributions of GCs observed in most large galaxies have, for decades, been interpreted as bimodal metallicity distributions, indicating the presence of two populations within a galaxy. However, the conventional view has been challenged by a new theory that non-linear GC color-metallicity relations can cause a bimodal color distribution even from a single-peaked metallicity distribution. Using photometric and spectroscopic data of NGC 5128 GCs in combination with stellar population simulation models, we examine the effect of non-linearity in GC color-metallicity relations on transformation of the color distributions into the metallicity distributions. Although in some colors offsets are present between observations and models for the color-metallicity relations, their overall shape agrees well for various colors. After the offsets are corrected, the observed spectroscopic metallicity distribution is well reproduced via modeled color-metallicity relations from various color distributions having different morphologies. We discuss the implications of our results.

We present a study of the metallicity of the old open cluster NGC 1245 , based on the Washington CCD photometry obtained using the 0.6 m telescope at the Sobaeksan Observatory, Korea. NGC 1245 has been known to be a unique cluster among the known open clusters in the sense that the previous metallicity estimates for this cluster are much larger $(by\;\sigma)$ than the value expected from the radial metallicity gradient of the old open clusters in Our galaxy. We have estimated the metallicity of the cluster red giants using the four color-color diagrams, obtaining a value for the mean metallicity of $[Fe/H] = -0.04\pm0.05$ dex. The total error including the error of the metallicity calibration, 0.15 dex, is 0.16 dex. The metallicity estimate of NGC 1245 we have obtained in this study is smaller than previous estimates, and is consistent with the radial metallicity gradient of the old open clusters, showing that the mean metallicity of NGC 1245 is not abnormally high. The reddening, distance, and age of the cluster have also been derived using the isochrones based on the convective overshooting models: the reddening $E(B-V) = 0.28\pm0.03$; the distance $d = 2.5\pm0.2 kpc$ (the corresponding galactocentric distance is RGC = 10.7 kpc, and the distance from the galactic plane is z = -0.4 kpc); and the age $t = 1.1\pm0.1 Gyrs$.

The purpose of this study was to investigate the effect of age, physical type and job on preference for color and fabric motifs in men's clothing design. Color preference measures consisted of clothing styles painted in CAD. Preference for fabric motifs was assesed by stripe fabrics in size, width and strength. All of the preference measures were devised specifically for this study. Furthermore, items on Hight and Weight for physical type, age and job of subjects were included I the questionnaire. Data were obtained by self-administered questionnaires form 243 men (25-54 years old) in Seoul. Analysis was by chi-square (X2), frequency, and percentage. The results obtained in this study were as follows : 1. Color preference was not affected by age and physical type, Job was related to coordinate color of men's clothing. 2. Preference for width of striped motifs was affected by age and job. 3. Preference for strength of fabric motifs in men's jacket was affected by physical type.

The inconsistent city planning damaged the city's landscape & identity, the old days. Nowadays the central and local governments are interested in the city's landscape design for residents, economic reason, etc. Color is most efficient one of design elements to improve a city landscape. So to establish the uniqueness and beauty of Gunsan city landscape, this study was performed to find out Gunsan landscape colors to survey the landscape color, by priority. There are nature environment of sea, river, reservoir, mountains and plain and artificial environment of buildings used japanese occupation period, them in early modern era and modern things. It found out the color palette has extracted from the present colors in the city landscape. There were mostly colors with low chroma, middle value and the next thing was them with high value. The blue among hue was strong. The Chroma was very low to be concentrated in $L^*$ axis. So achromatic color or blue/green of middle value and low chroma were recommended for dominant color and the similar color of former color was good for assort color in Gunsan city landscape.

The origin of globular cluster (GC) color bimodality, which is one of the salient phenomena observed in most large galaxies, has not yet been fully resolved. The phenomenon has conventionally been interpreted as a bimodal metallicity distribution based on an assumption of linear GC color-metallicity relations (CMRs). Recent studies however suggest that nonlinear GC CMRs can cause a bimodal color distribution even from a single-peaked metallicity spread. Using photometric and spectroscopic data on GCs in NGC 5128 (Cen A) and NGC 4594 (Sombrero), we investigate the nonlinearity of GC CMRs and compare the observed GC CMRs with the predictions of stellar population simulation models. Our careful selection of old GCs effectively reduces the scatter and reveals the nonlinear nature of the GC CMRs for various colors. The overall shape of the observed CMRs agrees well with that of the modeled CMRs, while offsets are present for some colors. We discuss the implications of our results in terms of the GC color bimodality and GC formation in NGC 5128 and NGC 4594.

Vintage fashion is a lot influenced by colors because an emotion is transmitted via images of "old feeling", "worn-out feeling" and "faded feeling" etc. Colors are visual sensation occurring at a time when lights stimulate an eye, which is a representative factor which humans first perceive when they touch objects. And colors in clothing function as a critical element which indicates an individual's impression and character as well as aesthetic sensation. In this study, I examined on the theoretical consideration and aesthetic characteristics via the previous literature on vintage fashion and colors. As an empirical study, I investigated on the colors of vintage fashion appearing in Pr$\hat{e}$t-$\grave{a}$-porter Collections, Paris from Spring/Summer, 2003 to Fall/Winter 2008. As a way for study, I investigated into the total 197 vintage fashion photos and calculated their RGB values by using photoshop. And I converted the values of the colors extracted into H V/C values by using Munsell Conversion Version 9.0.6 and analyzed on Munsell System of 10 Color Notation and the PCCS colors, classifying a color scheme by visual sensation measurement. The result of analyzing on the concept of vintage fashion and its color characteristics is as follows; Vintage fashion made an appearance the most in 2003 and 2004 and its colors appeared a lot in Y, YR, R and PB lines. Color tone concentrated on black and white, achromatic color and low chroma colors in a grayish line, chromatic color. Thus, the study found that colors suitable for a "worn-out", "faded" and "old" image are properly reflected in vintage fashion rather than a clear and bright background. In a color scheme, I found contrast color and same color appearing a lot, which gave an unharmonious feeling and a smack of the country. The study reveals that the color characteristic of vintage fashion is relatively diverse and complex in color, color tone or shade and color scheme, which shows a color trend which reflects a non-constructive and complex coordination characteristic instead of a standardized simple and clear image.

Koreans have regarded the red as a major color from old times. The red is a traditional color to have symbols of high position, national foundation and especially royalty. So, we can see the reds in the palace for kings very much.The purpose of this study is to draw out the features of color red in the Kyungbok palace. The color was analyzed by two categories-architectural buildings${\cdot}$structures and ornamental painted patterns. The major findings from this research are summarized as follows:1. Seokganju(similar to terra rossa) and toyugsaek(light seokganju) are found main colors in architectural space, while seokganju has a linear effect and toyuk has a facial effect. 2. Yugsaek(similar to light vermillion) and Jangdan(similar to orange) are found main colors in ornamental painted patterns. These colors are more vivid and brighter than those for architectural space.3. As for two-color combination, reds and blues(including greens) are found major combination both of architectural space and ornamental patterns. And reds and white are the following combination, which gives an bright image by white. 4. As for three-color combination, red-white-black combination of pediment and red-blue-white combination of openings are found very popular in architectural space, while red-blue-yellow combination is most popular in ornamental patterns.The reds are found dominant color of both architectural space and ornamental patterns in the Kyungbok palace. The color design as shown in the Kyungbok palace can be considered as the feature of traditional color design.

Globular cluster (GC) systems in most galaxies, particularly in ellipticals, show bimodal color distributions. Because broadband colors trace metallicity at old ages, this phenomenon has been commonly interpreted as bimodal metallicity distributions, implying the presence of two sub-populations in the globular cluster system within a galaxy. However, a new explanation has recently been proposed, in which the non-linear nature of color-metallicity relations induced by horizontal-branch stars can produce bimodal color distributions even from unimodal metallicity distributions. In this study, we put these two explanations to the test on the origin of color bimodality, using multi-band (U,B,V and I) photometry of globular clusters in NGC 1399, the central giant elliptical galaxy in Fornax galaxy cluster. We find significant changes in the morphology of color distributions when using different colors. The observation is also well reproduced by the Monte Carlo realization of GC color when a unimodal metallicity distribution and the theoretical non-linear color-metallicity relations are assumed. We discuss the implications regarding theories on galaxy formation and evolution.

Movie clothing is what is recreated as a character in work after being worn for actors (or actresses). And it is not added for heightening only fantasy but it acts for heightening only fantasy but it acts for reinforcing the side of character or subject. Especially the clothing in color movie gets to have very psychological effect. Thus Accord-ing to the clothing the effect of the represen-tation style may become large and small. So as to make the gesture or attitude of each character valuable in accordance with the ac-tion and expression of the figure clothing is different from other device essentially One may attain various goals through the color of movie clothing, First movie clothing may show the vogue color of the time and the representative time color, Second the color of movie clothing helps one to able to recognize the socio-econmic position of character easily as the color to symbolize the specific jobs such as nurse soldier and doctor etc. Third the color of movie clothing may show the charcter temperament as to whether one is young or old and whether one has pessi-mistic temperament or one is extrovert or introversive etc. easily. Fourth setting the clothing color of hero as the color to set off helps it easy to distinguish from representation staffs. Fifty the whole color establishment of movie clothing gives help to expressing the at-mosphere of movie. Color is one of the most powerful means that the person in charge of clothing may express the character of movie. He should ex-press the feature of a wearer with the colors of each clothing through showing the lack of taste of characters or hinting the resistant character with the clothing color which is not suitable for situation or the conservative character with suppressed color etc. Thus he (or she) should express the clothing color which is suitable for being able to express each character by analyzing the work whole through script and grasping the character of each character so as to establish the clothing which is suitable for individual character.
