For the autonomy of a mobile robot it is first needed to know its position and orientation. Various methods of estimating the position of a robot have been developed. However, it is still difficult to localize the robot without any initial position or orientation. In this paper we present the method how to make the colored map and how to calculate the position and direction of a robot using the angle data of an omnidirectional image. The wall of the map is rendered with the corresponding color images and the color histograms of images and the coordinates of feature points are stored in the map. Then a mobile robot gets the color omnidirectional image at arbitrary position and orientation, segments it and recognizes objects by multiple color indexing. Using the information of recognized objects robot can have enough feature points and localize itself.

The purpose of this study was to research of color symbol on white in the Virgin Mary and an Infant jesus icons. For this purpose icons were selected and analyzed from the medieval ages to the 18th century. The results were as follows. Icons on the subject of the Annnunciation and the Nativity should be expressive of nobility immaculacy and innocence of the Virgin Mary and an Infant Jesus. With this view white was used to be color of candle a waxing moon lily kettle dress bedspredad towel wall encircled garden and became symbolic color in the Icons. As a result the color symbol of white the meaning of immaculacy and innocence disseminated according to spread of the Christian religion. In these days though elimination of the religious meaning the white color is using continuosly as a symbolic color of immaculacy and innocence.

As various colors are used indoors and such colors influence on the image of indoors, color selection and color combination are a very important issue in inferior design. The purpose of this study is to analyse characteristic of color usage in interior design elements such as the floor, the wall, the ceiling and furnitures. The result of analysis shows the frequently used Munsell code corresponding to the cmyk code. Based on this analysis, this paper classifies largely into two kinds of the color combination type which can be used leer efficient color selection with good harmony The first combination type is divided into five types and the second is classified into three types. This paper argues that combination design principle, as a strong design tool, for color should be further developed for good quality of color design.

이 연구에서는 사찰벽화에 사용된 안료에 대한 성분 분석 자료들을 종합, 비교하여 조선 후기 사찰 벽화에 사용된 채색재료의 특징을 고찰하였다. 연구대상은 ED-XRF를 이용한 분석자료로 전국의 8개 사찰벽화 61점에 대한 것이다. 이들 벽화의 제작 시기는 대체로 18~19세기에 해당한다. 벽화 채색층의 색상은 대략 7가지 계통으로 분류되며, 백색은 Pb, Fe, 육색은 Pb, Ca, 황색은 Fe, 적색은 Fe, Pb, Hg, 녹색은 Cu, Fe, 청색은 As, Co가 검출되었고, 흑색에서는 색상원소가 검출되지 않았다. 자료들을 비교 분석해 본 결과 조선후기 경상도와 전라도 소재 사찰벽화에 사용된 안료들은 그 종류에 있어 시기나 지역적인 차이가 크게 관찰되지 않았다. 한편, 동종 안료라도 채색부위의 위치에 따라 다른 색상과의 혼색에 차이가 관찰되었다. 이것은 사찰벽화에서 선호되는 색상표현방식이나 안료의 귀천에 따라 그림에서의 위치(주제부와 주변부)에 따른 용도가 달랐음을 시사한다. 이러한 결과는 향후 비파괴 분석법을 이용한 사찰벽화 분석자료를 이해하는 데 참고자료로서 활용될 것으로 기대된다.

In order to increase the indoor air purification effect of plants, plants need to be placed on 5-10% of indoor spaces. To increase the density and utilization of plants in indoor spaces, studies on bio-wall, a vertical green wall system, have been recently conducted. The purpose of this study was to investigate the growth characteristics of 7 indoor plants introduced to the system and their rooting zones at different irrigation cycles. This study was conducted to investigate a proper irrigation cycle for the continuous maintenance of bio-wall systems. The conditions of their growth environment were maintained as follows: light intensity, 20-50 μmol·m^-2·s^-1 PPFD; and temperature, 20 - 25℃. For fertilization, Hyponex diluted with water at the ratio of 1:1,000 was supplied to plants. Irrigation was treated at intervals of 1, 3, 5, and 7 days for 1 hour at a time. As a result, there was no significant difference in the growth of plants between different irrigation cycles. Dieffenbachia 'Marianne' showed a significant decrease in the number of leaves at the irrigation cycle of 7 days. In addition, the chlorophyll content was relatively low at the irrigation cycle of 7 days. In terms of the color of leaves, a decrease in L value and b value and an increase in a value were observed, resulting in changes in brightness and color. Ardisia pusilla 'Variegata' showed a slightly higher photosynthetic activity and stomatal conductance when it was watered every day and once per 5 days, while Epipremnum aureum showed a relatively higher photosynthetic activity and stomatal conductance at the irrigation cycle of 3 days. In the case of root activity, it was found that the longer irrigation cycle, the higher root activity compared to daily irrigation. The development of roots of Peperomia clusiifolia was promoted by watering at long intervals. However, in the case of Aglaonema 'Siam-Aurora', the total number of roots decreased at the interval of 7 days. In conclusion, a proper irrigation cycle for the sustainable maintenance of vertical bio-wall systems seems to be 3 days.

Dunhuang murals are one of the most outstanding achievements in the art of traditional grotto painting in China, and are known as a "Wall Museum". As a representative of the heyday of Dunhuang murals, an in-depth exploration of Dunhuang murals from the perspective of color will help researchers understand the laws and connotations of color in Dunhuang murals during the Tang Dynasty and fully grasp the art of Dunhuang murals. The color system of the traditional Chinese "Five colors" concept expresses the cultural attributes and emotions of the Chinese people and has distinctive national characteristics. This thesis provides a theoretical grasp of the traditional Chinese "Five colors" view of color system, the Dunhuang murals of the Tang Dynasty, and the color configuration of the color composition principles, and uses the modern design principles of color composition to conduct an in-depth analysis of the configuration of the Dunhuang murals' use of color. Explore the unique characteristics of Tang Dynasty Dunhuang murals, and help modern designers master richer color application techniques by learning from and studying the harmonious patterns of Dunhuang murals to provide a new path for the dissemination of excellent Chinese traditional culture.

Bleached chemithermomechanical pulp (BCTMP) was produced from CTMP of Betula maximowicziana Regel by two staged ozone-hydrogen peroxide bleaching in order to improve the optical properties of high yield pulp. This pulp was used for the evaluation of optical properties improvement, chemical characteristics of lignin in fiber and the relationship between lignin and optical properties in fiber cell wall. Hydrogen peroxide treatment improved the brightness, but the post color number (PC No.). There was little improvement on optical properties by ozone treatment, but this could be improved more by using two staged ozone-hydrogen peroxide bleaching. The hydrogen peroxide treatment did not make any change on chemical characteristics of lignin in cell wall, but by ozone treatment, it was found that the non-aromatic conjugated structure was existed in the surface of cell wall, but this could be removed by hydrogen peroxide treatment in two staged ozone-hydrogen peroxide treatment. Therefore, the optical properties was significantly improved, due to the removal of non-aromatic conjugated structure.

The study investigated trends in wall-covering displays in interior design stores. Although studies reported design trends at well-known exhibitions overseas such as Heimtextil and Maison objet, many different cases present actual realistic design flows. This study analyzes the actual market flow rather than design as an exhibition concept, and presents the interior CMF trends in 2019. The CMF design of wall-covering displayed in New York D&D Building in 2019 can be summarized as follows: W was the most frequently seen show-window, but like R, which is a strong color, it is also used to convey surrealistic images. The store entrance was designed to attract consumers' attention inside, and was constructed to reflect the actual trend. In the 2019 New York market, the wall-covering of Gray and YR were displayed through the shop entrance to suggest substantial sales. In addition, the demand for gold metallic wall-covering is significant as gold was strong in many forms. This study represents a valuable resource to identify trends in wall-covering from 2017 to 2019 compared with previous studies. This study represents a valuable foundation for a wide range of topics related to the use of wall-covering for interior decoration.
