We describe a survey of quasars in the early universe beyond z=5, which is one of the main sciences of the Infrared Medium-deep Survey (IMS) performed by the Center for the Exploration of the Origin of the Universe (CEOU). We use multi-wavelength archival data such as SDSS, CFHTLS, UKIDSS, and SWIRE, which provide deep images over wide areas sufficient enough for searching high redshift quasars. In addition, we carried out a J-band imaging survey at the United Kingdom InfraRed Telescope (UKIRT) with a depth of ~23 AB and survey area of ~100 $deg^2$, which makes IMS the most suitable survey for finding high redshift quasars at z~7. Also for the quasar candidates at z~5.5, we are conducting observations with the Camera for QUasars in EArly uNiverse (CQUEAN), which are efficient for selecting robust quasar candidate samples in this redshift range. We used various color-color diagrams suitable to the specific redshift ranges, which can reduce the contaminating sources such as M/L/T dwarfs, low redshift galaxies, and instrumental defects. The high redshift quasars we are confirming can provide us with clues to the growth of super massive black holes since z~7. Also by expanding the quasar sample at 5

The importance of color is increasing in modern life and we call such present age that is 'color age'. These day that all areas of life are being getting fashionize, ordinary people as well as design specialist are required of culture and knowledge about color. Color design education is important curriculum at liberal arts course and in special design trainning course. Color expresses by hue, value and chroma in Munsell color system. But design spot is using mainly hue and tone color system. Therefore it is very important that educate tone concept in color design education. When think influence that increase of color, we must develop hue and tone color system in suitable for color design education. This research designed usable 'Hue and Tone 313 Colot System' for efficeint sensual color education. Also I designed 313 color papers with attached the Munsell notation which could reappear the spare color paper when needed. The 10 hues classification of this system are Red, Yellow Red, Yellow, Green Yellow, Green, Blue Green, Blue, Purple Blue, Purple, Red Purple. The 19 tones classification of this system are vivid, light, standard, deep, pale, soft, dull, dark, very pale, light grayish, medium grayish, dark grayish, very dark, off White, off Pale, off Light Gray, off Medium Gray, off Dark Gray, off Black. The special colors of this system are gold, silver and copper.

A 7-month-old brown pig with a discoid and pedunculate mass measuring $14.0{\times}12.5{\times}2.5cm$ on the skin of the right shoulder was noted at the slaughter house in Jeju. The surface of mass approximately $7{\times}4cm$ was interfaced with skin. The color of mass with firm consistency was mainly black and partially white on cut surface. Histopathologically, numerous unencapsulated endocrine-like cellular nodules of epithelioid cell type with abundant intracytoplasmic black pigment, melanin, were occupied in dermis and subcutis. Most of nodules in deep dermis were surrounded by lightly pigmented spindle cells and loose fibrous tissues. Mitotic figures were infrequently observed. The overlying epidermis was hyperplastic due to the down-growth of rete peg. Based on the gross and histopathologic findings, this case was diagnosed as cutaneous melanoma. In our best knowledge, this is the first case of swine cutaneous melanoma in Korea.

In recent, it is said that the trend of LCD is direction to pursue high qualities like as high transmittance, high contrast ratio, wide viewing angle, fast response time, and so on. Especially, it is known that these qualities are essential to large size LCD like as LCD TV and we can realize them through to uniform cell gap and deep black state. Until now, the ball spacer has been used to control of uniform cell gap. However, the existence of ball spacer inside the cell causes the deformation of the liquid crystal molecules and damage to alignment layer. Such a deformation of the liquid crystal causes light-leakage in the dark state, which lowers contrast ratio of the display. Nowadays, this problem has been solved by using Patterned Spacer on Color Filter. but Side Effect just as gravity mura has been induced. In this paper, we studied the mechanism on gravity mura in case of using patterned spacer on color filter.

A high redshift quasar is useful to investigate the early part of our universe. Since they are one of the brightest objects in the early universe, they can provide us with clues of the growth of super massive black holes and the early metal enrichment history. To discover the high redshift quasars, we designed a survey of wide area and moderate depth; Infrared Medium-deep Survey (IMS), a J-band imaging survey of ~200 $deg^2$ area where the multi-wavelength data sets exist. To obtain the J-band data, we are using the United Kingdom Infra-Red Telescope (UKIRT), and so far we have covered ~20 $deg^2$ with Y- or J-bands over three observing runs during 2009. We used color-color diagrams of multi-wavelength bands including i, z, Y, J, K, $3.6{\mu}m$ and $4.5{\mu}m$ to select high redshift quasars. The major challenge in the selection is many M/L/T dwarfs, low redshift galaxies, and instrumental defects that can be mistaken as a high redshift quasar. We describe how such contaminating sources can be excluded by adopting multiple color-color diagrams and eye-ball inspections. So far, our selection reveals two quasar candidates at z~7.

We used color-color diagrams of multi-wavelength bands including i, z, Y, J, K, $3.6{\mu}m$ and $4.5{\mu}m$ to select high redshift quasars. The major challenge in the selection is many M/L/T dwarfs, low redshift galaxies, and instrumental defects that can be mistaken as a high redshift quasar. We describe how such contaminating sources can be excluded by adopting multiple color-color diagrams and eye-ball inspections. So far, our selection reveals one quasar candidates at z~7 and a few candidates at z~6. In this poster presentation, we will update the current status of the quasar selection in the IMS fields.

Detecting shadows in images and restoring or removing them was a very challenging task in computer vision. Traditional researches used color information, edges, and thresholds to detect shadows, but there were errors such as not considering the penumbra area of shadow or even detecting a black area that is not a shadow. Deep learning has been successful in various fields of computer vision, and research on applying deep learning has started in the field of shadow detection and removal. However, it was very difficult and time-consuming to collect data for network learning, and there were many limited conditions for shooting. In particular, it was more difficult to obtain shadow data from buildings and satellite images, which hindered the progress of the research. In this paper, we propose a method for generating shadow data from buildings and satellites using Unity3D. In the virtual Unity space, 3D objects existing in the real world were placed, and shadows were generated using lights effects to shoot. Through this, it is possible to get all three types of images (shadow-free, shadow image, shadow mask) necessary for shadow detection and removal when training deep learning networks. The method proposed in this paper contributes to helping the progress of the research by providing big data in the field of building or satellite shadow detection and removal research, which is difficult for learning deep learning networks due to the absence of data. And this can be a suboptimal method. We believe that we have contributed in that we can apply virtual data to test deep learning networks before applying real data.

This paper is a study on the expression of Clothing and Textiles recorded in $\ulcorner$Genjimonokatary (원씨물어)$\lrcorner$. This book is a novel written by a Japanese sextant worked in the Royal Court around the year 1010. In this book, about 110 different kinds of Garments, Ornaments, Colors and Materials were mentioned. The results of this paper were as follows. 1. About the Garments 8f Ornaments ; All the Clothing and Textiles in $\ulcorner$Genjimonkatary$\lrcorner$ were reflections of the reality of that time. In the Clothing, Color, Textile and even Hair style, the Symbol of Buddism appeared. Many technical methods were developed in the garment shaping, dyeng and wearing methods. 2. About the Colors Sf Dyes; There were many kinds of Color SE Dyes described in $\ulcorner$Genjimonokatary$\lrcorner$. This means color was developed more than other elements in that period. Among them, gray and black colors were mentioned, this means Buddist Color was fashioned in that period. $\ulcorner$Kasaneno-irome (강색목)$\lrcorner$ was changed from Ungan (운간) that had been origined of China and Korea. But it became one of the Japanese Costume. That have some reasons, for instance, high materials could not be imported from other countris and many people were controlled by the Taboo of clothing (금제) so they wanted the better method, such as Kasaneno-irome. Many kinds of colors'name was origined from flowers and plants. It also represented the seasons. Yurusi-iro (청색) was meaning the permitable color to the popular people. Without the head word, Deep Color' and 'Pale Color' meant those things of the purple and red. 3. About the Materials IE Patterns : The materials imported from other country, China and Korea, were good in quality, but those produced in Japan were not good. There were many kinds of dyeing method, especially Srijome (신염) was very special and nice method in that period.
