In this paper, we present a new digital signature for copyright protection of digital images. The proposed algorithm is designed to be more robust to both the compression (quantization) errors and the illegal signature attack by a third party. More specifically, to maximize the watermaking effect, we embed the watermark by randomly adding or subtracking a fixed number instead of executing the XORs. Also, to improve the reliability of the watermark detection, we extact the watermark only on some image blocks, which are less sensitive to the compression error. Futhermore, the unrecovered compression errors are further detected by the Hypothesis testing. The illegal signalture attack of a third party is also protected by using some probabilistic decisions of the MSE between the orignal image and the signed image. Experimental results show that the peroposed algorithm is more robust to the quantization errors and illegal signature attack by a third party.

A pattern is a symbolic mark of the psychological expression and ornamental desire of the human interior. In particular, plant patterns, from ancient times to modern times, express beauty across both the east and the west. The Joseon dynasty had a strong national will, and it was a time when the symbolism of Korea was established. Plant patterns were decorative and symbolic, filled with meaning in both the textile and craft sectors. This study looked at the frequency and figurative characteristics of the types of plant patterns in textiles, ceramics, woodworking, and metal craftsmanship of the Joseon dynasty. In addition, pattern designs were developed by extracting unit patterns to maintain the original shape, and by adding, magnifying, reducing, and superimposing flat steps and employing the four-fold sequence. The data collected was 826 examples in textiles and crafts, and 34 species of plants were analyzed as follows. In general, the flower patterns preferred soft flowers, flowers, apricot, and peony patterns, and fruit patterns emerged as decorative designs for pottery and woodwork from the 17th century, featuring pomegranates, grapes, fluorines, peaches, and walnut floss. Textiles and woodwork were arranged with many circular designs, while pottery and metal crafts were filled in many ways. Expressive types appeared to be the same as stylistic types for textiles and ceramics, and the construction types were the same in pottery and metal crafts. As such, it was found that even in the different areas of the sculpture, the same aesthetic values were reflected in the common figurative features today. Therefore, in this study, we developed a unique and competitive pattern design that accommodates the modern times and the Joseon dynasty. This development is expected to contribute not only to the development of cultural and tourism products in the future, but also to the tourism industry induced by the Korean wave.

The purpose of this study is to categorize the typs of fabrics and to analyze weaving method and pattern design on the silk fabrics from Jang-Gi Jung s tomb. The conclusions of this research are as follows. 1) Among the 32 pieces of excavated clothes, 90% of them were made of silk fabric and 65% used patterned silk. I would assume, therefore, that the tomb was owned by a person of higher society who could afford the best clothes of the time. 2) The weaving methods of silk include tabby, twill damask with different direction (2/1 warp faced ground, 1/3$\cdot$1/4 weft faced pathern), self-patterned satin damask (4/1 warp faces ground, 1/4 weft faced pattern), and brocaded satin damask. 3) The arrangement of the motifs and the kinds of patterns on these silk fabric can be divided into two categories: first group is allover arrangement of peony or lotus and second group is the scattered arrangement of omen of luck. 4) Two pieces of fabric was stamped and the letters of the stamp make me to think about the possibility that the fabrics are from China. But to make this paint clear more relics of this kind should be excavated so that further research can be done.

Linked pearls pattern expressed on textiles have no limited scale or shape when manufacturing, so they are free in expression. And from the design, material, and color we can analogize the social culture of that age. Oriental linked pearls pattern was started from the Sasanian Persia and introduced through the Silk Road, so it is closely connected with the East and the West culture. This study will consider from the 5th century to the 10th century; the mural costume of the West Central Asia, the ancient textiles excavated from the Sinjiang and Qinghai area of China, and the linked pearls pattern which are collected at Shosoin, Japan. And from this study, will concentrate on clarifying the linked pearls pattern's condition of the cultural exchange between the East and the West and it's structural variation process. The design of linked pearls pattern delivered to the East through the Silk Road is differed by area. For example, in the Western Pamir Plateau, where the ancient Sogdians mainly lived, the excavated linked pearls pattern's subject were deer or cassowary variated from the West Asian motif. But the ones excavated from Kucha Xingang had Chinese motifs added so they showed Chinese characters or Buddhist Bodhisattva image instead of Helios. Like this, the appearance of new patterns, which were accompanied by structural variations, gradually deviated from the standardized pattern of the Sasanian Persia. And this structural variation process has relations with the construction and arrangement method of various patterns of the after ages. The foliated floral Spray, which is placed at the lozenge space of linked pearls' space, had developed into ogival - shaped pattern (Neunghwamun). And the prevalence of geometrical structure pattern after the 10th century and the unfolding method of Tapjamun which is arranging unit pattern in order, are similar to the linked pearl pattern. In brief, linked pearls pattern accompanied by technical improvement let us understand the polished artistic code from its expression, and has importance in showing universal pattern beyond region and culture.

Anatomical and physical characteristics of seven cultivars of chestnut wood (Castanea crenata Sieb. et Zucc.), Tanzawa, Ibuki, Mansung, Arima, Ginyose, Tsukuba, and Riheiguri, were investigated to obtain some valuable information for their possibilities to be used for high quality furnitures and woodcrafts. Solitary pore and figured-porous or ring-porous wood types were observed in wide growth rings, and ring-porous in narrow growth rings. Procumbent type was prevalent in ray cells although upright and square types were scarcely existed. Uniseriate, biseriate, and multiseriate rays were observed in tangential section. Uniseriate ray was abundant near the pith, and biseriate and multiseriate rays were frequently existed near the bark. The occurrence rate of biseriate and multiseriate rays was significantly high in Tanzawa, Ibuki, Mansung and Tsukuba, but was somewhat low in Arima, Ginyose and Riheiguri. The inner region showed larger vessel diameter, more vessel number, fewer ray number and higher ray height than the outer region. Growth-ring width in inner region was larger than that in outer region. Growth-rings in inner region of Mansung and Arima were wide while that of Ibuki was narrow. Outer region in all cultivars showed higher latewood percentage than inner region. Especially, Mansung and Tsukuba showed significantly high latewood percentage in their outer region. Green moisture content and density of heartwood were higher than those of sapwood. Tsukuba and Riheiguri had higher green moisture content, and Ibuki and Riheiguri had higher green density than the other chestnut cultivars.

This study derived a method for establishing the chronology of cloud patterns by examining the arrangement of the treasure motifs in the cloud pattern used in the relevant pattern-decorated book covers of 89 Oegyujanggak Uigwe books, which are currently housed in the National Museum of Korea. The cloud pattern with a treasure motif was used in the covers of a total of 89 books from King Hyojong Gukjangdogam Uigwe (1659) to Sadoseja Garyedogam Uigwe (1744), spanning 86 years. First, to analyze the cloud pattern, it should be broken down into smaller parts to the extent that the different shapes of treasure motifs can be recognized. Secondly, the method of decoding the pattern is as follows: First, check whether the pattern is arranged in one or two directions from the vertex of the cloud's head, and determine the direction of the cloud tail. Then, decode the treasure motif's arrangement starting from the vertex of the cloud's head toward the direction the tail of manja is headed. Record the findings of this decoding process by categorizing them. Thirdly, as a result of the analysis, a total of 28 types of cloud patterns with treasure motifs were identified in 89 books. There were 45 types of treasure motifs used in such patterns. Finally, we have concluded that applying the method of decoding the treasure motif in the cloud pattern to portraits, excavated costumes, and various relics can be useful to establish the chronology of cloud patterns in the late Joseon period. The method suggested in this study is called 'The Reading Method of Chronology in Cloud Pattern with Treasure Motifs' (also 'Jeung-ha Cloud Pattern Reading Method').
