This study uses the "Sejong chronicles" ritual manual to investigate the movements and roles of provincial governors during the enshrinement rituals of the royal portrait, the official uniforms of the provincial governors in their roles, and the characteristics of the official uniforms system for local governors in the early Joseon Dynasty. The results of this study are as follows. Provincial governors who participated in the enshrinement rituals of the royal portrait were governors 'en route' and governors 'in destination'. The movements of the governor 'en route' followed the provincial borders, official residences, and neighboring provincial borders. The movements of the governor 'in destination' followed the provincial borders, the official residence, and jinjeon. The roles of the governors included the welcoming ceremony, the bow-down ceremony, the front guard, and the farewell ceremony. The governors 'en route' wore Jobok in the welcome ceremony, and a Sibok in the bow-down ceremony before the farewell. The governor 'in destination' wore Jobok in the welcome ceremony, and Jobok (or Sibok if Jobok was not available) in the bow-down ceremony before the farewell. The characteristics of the official uniforms system for local governors in the Joseon Dynasty were as follows. First, the governors wore different uniforms depending on the importance of the rituals in the early Joseon Dynasty. Second, the names of official uniforms Sang-bok and Si-bok were used interchangeably in the early Joseon Dynasty. Third, local governors were allowed to wear Sangbok (or Sibok) instead of Jobok.

When analyzing make-up trends of figures shown in portraits of different eras in Chinese painting history, you can see that red color was used much. This can be because the red color is the most outstanding among all the colors and was most preferred by ancient people, as the color of the sun, the blood, and the sacredness. The women in the Tang Dynasty was especially using the red color much. Though Seongrihak (Neo-Confucianism) in Song Dynasty was the governing ideology, it had an influence even upon its aesthetics. Thus, during Song Dynasty, the beauty of logos appeared too. This phenomenon showed a conservative tendency even in make-up as well as in costume, thereby the concept of clear and elegant beauty was emphasized. The real figure in the Ming and Ching Dynasty, was so young and weak as a sample of a delicate woman that a woman who had feminine beauty was regarded as an ideal type. The feminine image had been gradually generalized from the literary works in the latter half of Ming Dynasty. However, the painters in the era still preferred the beauty of a healthy woman. That tendency probably had an influence even upon make-up culture that was shown in portrait. As an analysis result of make-up culture in Chinese portrait paintings, it reveals that ancient make-up trends much reflected the social and cultural phenomena of the periods.

Considering dynamic behaviors according to initial tension forces, geometric nonlinearity and the effect of higher eigen modes to participate in dynamic behaviors increase as initial tension forces decrease, and from phase portrait we can realize that period attractors are produced in many area with complexity. If initial tension forxes increase, difference between linear and nonlinear solutions will decrease and the first eigen mode dominate the dynamic behaviors and observing phase portrait, period attractors appear in certain area regularly. These results may offer meaningful informations to nonlinear dynamic analysis using modal reduction methods such as Lanczos modal analysis. And actually nonlinear dynamic analysis needs very large computational efforts. So, if we determine the number of eigen modes to take part in modal analysis corresponding to initial tension forces we will get more accurate data close to exact nonlinear dynamic solutions.

The portrait featuring Jo Ban(1341-1401), a scholar-official from the late Goryeo and early Joseon period, and his wife is the oldest surviving couple portrait in Korea. It is of great value in uncovering the clothing culture of the period given the limited number of historical artifacts and records. This study examines the historical clothing and textile patterns of Jo Ban's wife and reproduces them using 3D fashion design software program CLO. She wears jokduri, chima, and baeja over layers of jeogori, a mixture of traditional Korean and Chinese styles. Her clothing illustrates eight patterns-one flower, five geometric, and two cloud. Records and relics of similar periods show that flower and geometric patterns in her clothing follow the prevailing styles of Goryeo, while the cloud patterns are representative of early Joseon. These details are used to reproduce six different styles of Jo Ban's wife with CLO tools. Various visualizations of textile patterns are applied to materials, generating a more realistic look than her existing 3D character created with the portrait. Results of this study are expected to help promote the use of Goryeo clothing and patterns in numerous designs and enhance intuitive understanding of Goryeo clothing based on 3D visualization.

The purpose of this study is to examine the power images in the style of a leader: through the focus on the portrait of Henry VIII. Study methods on the literature concerning viewpoints of power and image in the early modern age and the subjects of power are being used for theoretical backgrounds; and the visual data from National Portrait Gallery, British Library and the internet are used for exploratory studies. The results of this study are as follows. First, from the style of Henry VIII who represented the image of political power, the modern political phenomenon can be defined. Such phenomenon which displays images of political leaders from the study indicate an effective strategy. Second, the religious, a diplomatic representation for the style of Henry VIII powers, such as costume style and somatic visual images, represents the dignity and power by delivering visible internal attributes. Thus, the role model recognized by the society and the public's perception of leadership style affects the acknowledgement and belief by the people.

This paper proposes a novel control method using phase plane for a hydraulic biped humanoid robot. In biped walking control, it is much more difficult to control the posture of a biped robot in the coronal plane because the supporting area formed by the both feet in the coronal plane is much narrower than that of the sagittal plane. When the biped robot walks stably, the phase portrait of the pelvis in the coronal plane makes an elliptical shape. From this point of view, we develop an ankle torque controller and a foot placement controller for tracking the desired phase portrait during walking. We design these controllers by using simulations of a simplified compass gait biped model to regulate the desired phase portrait of pelvis. The effectiveness of the proposed control method is proved through full-body dynamic walking simulations and real experiments of the SARCOS hydraulic biped humanoid.

The purpose of this study is to inquire original design and character of dancheong in Yeongnamnu P avilion which features unusual portraits of twisting dragons and four heavenly creatures. Its artistic value and originality can be found in the portraits of four heavenly creatures which are painted on the interior seonjayeon(fan shape rafter) and in the unique design of crossbeam meoricho(flower decorations on each side of pillars). Yeongnamnu's crossbeam meoricho is janggu-meoricho type(meoricho with hourglass figure) with full-shape lotus and half-shape flower decorations. And it can be said that, dragon portrait painted on the border of lotus and flower decorations in green and yellow is a very unique style of dancheong, for the reason that it has scarcely been used before and ever since. The portrait of four heavenly creatures painted on each corner of seonjayeon is also found to be unique in design, for the reason that the design has rarely been used throughout history, with only two exceptions in mural tombs of Goguryeo and folding screen in Injeongjeon Hall of Changdeokgung P alace. With its unique and authentic feature along with its rarity in number, the portrait of four heavenly creatures painted on Yeongnamnu can be considered as quite symbolic and important.

The aim of this study was to reproduce the ordinary attire of Yi Seung-hyu, a civil official and writer of the late Goryeo, which will be used to make a his portrait. The reproduced costume consists of a single-layered pyoui (表衣) and jungdan (中單), lined jeogori and baji, and geon (巾), created with reference to historical documents, materials, and portraits. The pyoui was made with samcheokbe, with an H-shaped neck-shoulder band, an oblique single collar, and rectangular gussets. Two skirts were attached on the inside at the back, similarly to dopo. The jungdan also has an oblique single collar, but has an I-shaped neck-shoulder band and triangular gussets. A flat felled seam stitch, whip stitch, and French seam stitch were used in the hemlines and seams of the pyoui and jungdan. The jeogori and baji were made with toju (土紬), and small ties were attached to stabilize them. The geon is a long, oblique hat, which has folded side lines, and was made with flexible black hangra and using a French seam stitch and backstitch. The results include the elements of "restoration, historical research, and portrait costume", and will be maintained as the cultural heritage of Samcheok City.

Yuso is the term for decorative tassels of a braided string which hangs a scroll painting. This study, drawing on extant research concerning the yuso made for Joseon period portrait scrolls of kings and meritorious retainers, focuses on the yuso created to hang literati portraits. Concretely, It examines yuso of seven portraits in the collection of the National Museum of Korea in order to characterize their appearance and determine their material composition. The study found that most of the yuso are sixteen-strand strings braided into a rounded cross-section(dongdahoe). The seven yuso, of which six are red and one indigo-blue, reflect the popular style associated with Joseon period literati portraits. The yuso for the portrait of Yun Geup(duksu 3503) is made from gilded paper. Analysis showed Fe particles present in a red pigment underlying the gold layer, suggesting the presence of red ochre(seokganju), an iron oxide mineral. The yuso of the portrait of Shin Im(duksu 4846) is used a paper which contains gold as well as traces of Pb, Hg and Ag. The paper in the yuso for the portrait of Yi Seongwon(bongwan 10122) mainly consisted of Ag, indicating silver paper having been used in its fabrication. The inner paper in the yuso of the portrait of Yi Seogu(sinsu 1065) is a leather combined with Ag, Fe, and Br, according to chemical analysis. The FTIR of the leather sample reveals that the spectrum in the fingerprint region is nearly identical to that of sheepskin, indicating the yuso was made from gold-coated sheepskin.

The skin-tone in portrait photography is one of the most sensitive parts that need retouching by a photographer. To investigate the emotional reactions related to users' preferences for the skin-tone variations in portrait photography, two experiments were conducted. The first experiment included JND(Just Noticeable Difference) test to determine the general distribution of preferences with many photographs that varied in phases up to an extreme one, as a result, preferences for the brightest skin-tone and the red or magenta one were found. Based on the first experiment, we reduced the number of samples by adjusting their brightness to the brightest phase constantly. To intensify the second experiment, we reduced the number of the other colored samples to only one and made samples for five phases from green to magenta, namely the most preferred skin-tone in the first experiment. In the second experiment, the common preference for a neutral skin-tone and the partial difference between the two gender groups were found. In conclusion, the users' preference for a particular skin-tone was positively affected by emotions such as 'happiness' or 'comfortable'. With this investigation, we compiled some statistically meaningful facts to confirm that the preferences of the users depend positively on controlling the skin-tone in portrait photography.
