We present our study of analyzing the photometric properties of the globular cluster (GC) system which resides in the extended halo of the central bright Coma cluster galaxy NGC 4874. The core of the Coma cluster of galaxies (Abell 1656) was observed with both the HST Advanced Camera for Surveys (ACS) in the F475W (g475) and F814W (I814) and Wide Field Camera 3 IR Channel (WFC3/IR) in the F160W (H160) filters. The data analysis procedure and GC candidate selection criteria are briefly described. We investigate the interesting "tilt" features in color-magnitude diagrams for this GC system and their link to the nonlinear color-metallicity relation for GCs. The NGC 4874's GC system exhibits a bimodal distribution in the optical g475-I814 color and much more than half the GCs fall in the red side at g475-I814 ~ 1.1. This bimodality is weakened in the optical-IR I814-H160 color; the quantitative analysis on the features of both color distributions using the Gaussian Mixture Modeling code proves the bimodalities are different. Both colors, thus, cannot linearly reflect the bimodality of an underlying metallicity, supporting the suggestion that observed bimodalities in extragalactic GC colors are the metallicity-to-color projection effect.

The purpose of this study is to investigate material designation in library cataloging and to suggest General Material Designation (GMD) and Specific Material Designation(SMD) in Korean. A summary of the study follows. In library cataloging, methods of indicating the type of material are : (1) color-coding, (2) media code as part of the call number, (3) material designation in physical description area or note area, (4) GMD and SMD. GMD is a term indicating the broad class of material to which a bibliographic item belongs. SMD is a term indicating the special class of material to which a bibliographic item belongs. GMD was listed in parenthesis following the title proper before AACR1975 code, but currently it is listed in square brackets after the AACR1975 code. AACR2 was the standard cataloging rule in GMD and SMD terminology. It is suggested that GMD be used in Korean for graphic material, sound recordings, drawings, microform, multimedia, videorecordings, manuscripts, photographs, slides, printed music, motion pictures, printed texts, objects, braille, cartographic materials, computer files and transparenies.

The container BIC-code is a transport protocol for convenience in international shipping and combined transport environment. It is an identification code of a marine transport container which displays a wide variety of information including country's code. Recently, transportation through aircrafts and ships continues to rise. Thus fast and accurate processes are required in the ports to manage transportation. Accordingly, in this paper, we propose a BIC-code region extraction and recognition method using multiple thresholds. In the code recognition, applying a fixed threshold is not reasonable due to a variety of illumination conditions caused by change of weather, lightening, camera position, color of the container and so on. Thus, the proposed method selects the best recognition result at the final stage after applying multiple thresholds to recognition. For each threshold, we performs binarization, labeling, BIC-code pattern decision (horizontal or vertical pattern) by morphological close operation, and character separation from the BIC-code. Then, each characters is recognized by template matching. Finally we measure recognition confidence scores for all the thresholds and choose the best one. Experimental results show that the proposed method yields accurate recognition for the container BIC-code with robustness to illumination change.

일반적으로 인간은 외부로부터 정보의 85% 이상을 '시각'을 통해 얻고 있으며 색(色)-형(形)-Texture(質感)의 순으로 사물을 인식한다. 그래서 인간은 예전부터 위험상황에 대응하기 위해 대상의 정보를 신속하게 전달하는 수단으로 색채를 활용해 왔으며, 안전색채는 이러한 색의 속성을 이용 위험으로부터 안전을 확보하기 위해 적용되어왔다. 현재 안전에 관한 정보를 제공하는 시스템에는 언어나 문자사용을 가능한 한 사용하지 않고 안전표지를 국제적으로 표준화하여 사용하는 것이 바람직하며 실제로 국제표준기구(ISO)가 제정한 '안전색채 및 안전표지(ISO3864)'를 채택하거나 자국의 실정에 맞춰 일부 변경 사용하고 있다. 또한 안전표지는 색만이 아니고 그것을 표시하는 형까지 포함 사용되며 형태는 표시 물건에 따라 다양하며 또한 색채가 일으키는 심리 작용을 이용하여 주의를 환기하거나 위험을 경고하며 위험방지 및 긴급사태에 대한 대응을 목적으로 하고 있다. 안전색채 및 안전표지의 목적은 안전 및 건강에 영향을 미치는 대상물 및 장소에 신속하게 주의를 촉구하는데 있다. 따라서 본 연구에서는 안전색채와 안전표지에 대해 알아보고 이를 사용한 실례를 통하여 안전색채와 안전표지의 색채 및 디자인에 대해 알아보고자 한다.

Examine the dress which the Emperor actually wore in Gun-ryung 42nd year of Ching dynasty, comparison of 《Cheong-hoi-jeon-do》 with the Emperors year-round dress in Gun-ryung the 41st year was made and summarize the result as follows. It was used almost similar to the code of 《Cheong-hoi-jeon-do》. Though the materials and colors were more diverse than those of the previous year, it seems that actual use of material was plain under the influence of mourning. All the materials for summer hat were rattans. And velvet was the material for the patrol hat, but actually used before they change to summer material after fur use was over according to the season, which can be said as more reasonable use than the code. Materials of coat were more diverse than the precious year and also they put on ko-hemp cloth which was not found in the previous year. This can be understood that they expressed their guilt-consciousness to the dead as dress material by wearing ko-hemp cloth during the summer after periiod of mourning was over. And they put on the ko-hemp, the Emperors ordinary dress, much longer time than the previous year and this seems to be coherent to the meaning of wearing ko-hemp cloth. They followed the Emperor\`s Jo-bok1 one for the Kae-bok which were not systematized and Jae-dae used Jo-dae2 as the Emperor\`s Jae-bok in 42nd year. This was the same as the Jae-bok code of the previous year. Jo-ju did not follow the code of 《Cheong-hoi-jeon-do》, but made a wide variety. For the belt, the same as 41st year, it marked the gem decoration style on the Jae-bok belt as a square type and mourning dress by using the round type. The Emperors dress in 41nd year showed one side of the patrol clothes by the patrol of San-dong. On the contrary, it was also the chance to see one side of funeral garments in 42nd year. In Gun-ryung 42nd year, the Emperor put on the funeral garments for hundred days. Accordingly even in parts, we can see that the Emperor wore two kinds of dress for hundred days, that is, color dress and white dress and white dress. While on duty, in other words, everyday dress was only blue color and also the same color for the belt and shoes. But didn\`t put on Jo-ju. When they were in mourning, they wore white dress and belt as a funeral garments, which were called Hyo-bok, Hyo-bok.

This paper examined the performance of differentiated services applied to each different traffic. For this purpose, we used three traffics which have a different quality of service and generate packets from a specific source to destination. To allocate a proper code point according to QoS, a common policy which is the simple policy model of time sliding window with 3 color marking (TSW3CM) was established to each traffic. To evaluate the performance, we investigate and compare code points to each traffic. Simulation results using NS-2 showed that the code points 10, 11, and 12 can be differently allocated to each traffic according to its sending rates 1Mbps, 2.5Mbps, and 4Mbps.

To reduce the effect of color distortions on reading colors, it is more desirable to statistically process as many pixels in the individual color region as possible. This process may require segmentation, which usually requires edge detection. However, edges in color codes can be disconnected due to various distortions such as dark current, color cross, zipper effect, shade and reflection, to name a few. Edge linking is also a difficult process. In this paper, k-means clustering was performed on the images where edge detectors failed segmentation. Experiments were conducted on 311 images taken in different environments with different cameras. The primary and secondary colors were randomly selected for each color code region. While segmentation rate by edge detectors was 89.4%, the proposed method increased it to 99.4%. Color recognition was performed based on hue, a*, and b* components, with the accuracy of 100% for the successfully segmented cases.

Identifying color codes needs precise color information of their constituents, and is far from trivial because colors usually suffer severe distortions throughout the entire procedures from printing to acquiring image data. To accomplish accurate identification of colors, we need a reliable segmentation method to separate different color regions from each other, which would enable us to process the whole pixels in the region of a color statistically, instead of a subset of pixels in the region. Color image segmentation can be accomplished by performing edge detection on component image(s). In this paper, we separately detected edges on component images from RGB, HSI, and YIQ color models, and performed mathematical analyses and experiments to find out a pair of component images that provided the best edge image when combined. The best result was obtained by combining Y- and R-component edge images.

This study offers data that can be used to direct the styles of black dresses by looking into the characteristics of coordination in black fashion, which is continuously appearing at modem. fashion collections with a unique aesthetic value and image. This study examined the characteristic of fashion coordination of black color: First, to look at the fashion image of black color, second, to look at the characteristic of black color coordination appearing in black fashion, and third, to look at the method of coordination appearing in black color. This study collected and selected 560 black pictures that showed the fashion collections from 2005 S/S until 2007 F/W. As for data analysis, the researcher made a content analysis by classifying the pictures by item, material, accessory, and a coordination method. The research results are as follows: First, the fashion image of black color was expressed as sexy feminine, modern chic, modern future, genderless, and avant-garde images. Second, the fashion coordination of black color has the characteristics of sexiness and dignity by the use of body exposure, concealment, and a subdued line that expresses a modern, minimal atmosphere. The mix & match of materials expressed the monotony of one color as refined beauty and the use of accessories appeared to bring the image into relief. Third, as for the coordination method, pants on skirts, pants on dresses, piece coordination of code matching, plus- one coordination through vivid colors and accessories, and cross-over coordination relying on shape, material, and sense were prominent.

The purpose of this study is to analyze the fashion style of Kate Middleton, the Royal Family, and to examine the social and cultural influence of Middleton fashion. We selected 314 photographs collected from a Google site and Gettyimages.com April 2011-December 2016 as the final research subjects. We categorized the situation by domestic events, royal events, diplomatic activities, and social contribution activities, and analyzed fashion styles focusing on item composition, color, material, silhouette, detail, trimming, and length. As a result of the study, the one piece was the highest in the combination of items, and the color was the most in white. The color tones were mostly vivid, and the material texture was silky. The image was classic, and the dress code was high in semi-formal. In a situational style, the coat was the most common at the Royal Family events and blue or white of the light tones appeared in the formal style of the classic image. In domestic events, there were many silky textures of modern image, and vivid, strong tonal knee length H line dress was the most prevalent. During diplomatic activities, various colors such as red, green, gray appeared in addition to blue or white and in social contribution activities, many dresses of vivid and dark tones of red appeared in the dress code as semi-formal. In conclusion, the stylistic features of Kate Middleton and the Royal Family are largely in the form of royal and noble, low cost and chic, and body-conscious styling.
