  • Four gilded bronze objects and a gilded silver object were examined for elemental diffusion between the gilding layer and the mating matrix. The gilded bronzes consist of three objects from three different historical periods, the Korean Three Kingdoms period, the Koryo and the Choseon periods and one from an unknown period. The gilded silver was from the Koryo period. The amalgam process seems to have been the major technique employed for all of them in gilding. The occurrence of substantial diffusion was observed in all but the anonymous object, particularly in the Choseon artifact where evidence was found that the diffusion phenomenon was intentionally utilized in gilding. The gold content in the gilded bronzes decreases gradually from surface to interior while the copper content increases to the interior, making it difficult to locate the boundary between the gilding layer and the matrix. This gradual change in composition must have resulted from elemental diffusion at elevated temperatures. The oxygen content negligible in the gilding layer precludes the possibility of corrosion being responsible for the varying composition. It is observed that non-uniform diffusion caused variation of colors in the surface of gilded bronzes. The change of colors induced by diffusion, which is always accompanied by the unique surface morphology and chemical compositions, is distinguished from the color change by corrosion. In the gilded silver object, diffusion of mercury was observed along with that of gold and silver.

  • The purpose of this article is to present the potential of balangandãs as a documentary source for intersectional studies of gender and slavery, from the analysis of formal and symbolic aspects of the museum objects in the Museu Nacional Nacional (MHN) and Museu Carlos Costa Pinto (MCCP). Balangandãs are a type of creole jewelry, made in gold or silver and used in Brazil since the 18th century by black women - women who worked, especially in the commercialization of foodstuffs in large urban centers. They are described in printed sources and engravings, and preserved in some museum institutions. In the study, the meanings attributed to the object over the centuries are observed: jewelry, amulet, peculium, document, travel memory and heritage. As a result, the article seeks to highlight the objects as a historical and documentary source, verifying similarities between the pieces musealized at the MHN and at the MCCP, also emphasizing the documental power of the pieces produced today.

  • In relation to the scientific conservation treatment of ancient gilt bronze, the gold film coated on the bronze excavated from Hwangnam Great Tomb of Old Silla Kingdom(A. D. 5C) was studied in the view of coating technology and metallurgy of bronze. The uniform and dense gold film containing $2.44\sim12.40%$ of Hg with the thickness of $5.99\sim12.97{\mu}m$ was found to be coated on the bronze objects by amalgam coating method. On silver objects, the film with the thickness of $19.96{\mu}m$ was coated also continously and uniformly with gold by the same method. The bronze objects was fabricated by forging technique and contained almost $4.7\sim11.5%$ of Pb. Its microstructure was $\alpha-phase$ solid solution including Pb segregation in the matrix. The amount of $0.4\sim2.0%$ Zn was added in the bronze for the purpose of easy fabricating of Cu alloy. Based on the data studied, the gold film on bronze sample was reproduced by amalgam coating method and compared with the ancient gold film.

  • This study explores grotesque characteristics that were raised as the Aesthetics of the Ugly and how it was featured in Alexander McQueen's arts. In a methodological approach, the study attempted the analysis of historical literature that was published both nationally and internationally, along with justifiable investigation using fashion/collection magazines such as Vogue, Gap and Internet search. The scope of this study ranges from 1996's Haute Couture and Pret-a-porter collection pieces modern, to date The results of this study are summarized as follows: The first grotesque characteristic present throughout Alexander Mcqueen's arts is that it featured horrifying images or evil motives with pointy heads or horns, dark colored dresses, silver accessories, Dracula, witches, skulls, soldiers of evil, death and sickness. Second, aversion was realistically portrayed by frightening objects, extreme intimacy and motives that signify death and closely relative to cruelty to human bodies. It also became visible with physical destruction of the bodies and dissecting of internal organs, etc. Thirdly, its expression of humor is out of common sense with distorted human bodies by intentionally overemphasizing certain portion of the clothes or body parts. It also featured strangely deformed bodies by ignoring the typical shapes of clothes, vague definition of gender and using of unusual objects. Forth, half-man and half-beast images are portrayed using various types of bird species or animals to Identify disparity. It further defined this image in the form of non-human cyborg by incorporating technology.

  • Konbaung Dynasty was the last unified dynasty that ruled Myanmar from 18th to 19th century. During this time Buddhist art flourished in Myanmar due to the interest of the rulers toward their traditional culture. Metal decorative artifacts in the 18th century are classified into structures and Buddha statues. They are further subdivided into gilt-bronze and bronze objects, depending on their material component. Three-dimensional gilt-bronze decorative artifacts were cast with a brass alloy of Cu-Zn-Sn-Pb and their surfaces were gilded with extremely thin gold leaves (less than 1 ㎛ in thickness). The gilded layer approximately comprised 10 wt% silver in addition to the main element, gold. The lack of Hg in the gilded layer, indicated that the amalgam gilding technique was not applied. The analysis results indicated that the lacquered gilding technique was applied to the objects. Bronze decorative artifacts without gilding were cast with materials containing Cu-Sn-Pb. The bronze pavilions and bronze Buddha staues were crafted using the same alloy of high-tin bronze, which approximately contained 20 wt% Sn. No heat treatment was applied to reduce the brittleness of the objects after they were cast with a large amount of Sn. The most significant difference between the gilt-bronze and bronze decorative artifacts lie in their elemental compositions. The gilt-bronze decorative artifacts with their gilded surface were manufactured using brass containing zinc, while the unplated bronze decorative artifacts were composed of bronze containing tin. Artifacts of the same type and size are classified differently depending on the materials utilized in the surface treatment such as gilding.

  • The button is a part of costume. But it has the symbolism of costume in itself and reflects the sociocultural phenomena. The purpose of this study is to clarify symbolism of button of eighteenth and nineteenth century which had been most popular. This study is based on the library research. Through this paper, I reached conclusions as follows. The symbolism of button is found in various ways. First, Aesthetics is found in material, color, design and type etc. of button. Especially Indian silver button of abstract type shows well distinctive aesthetics of Indians. Second, The material and the number of button vary with one's status and show off one's privilege. I England, there was the rule, in which the symbol of the King was a silver button with a figure of lion. The livery button represents his family to the nble and shows the meaning of obedience to the servant. Third, The button on uniform varies with ranks. This is prominent in a uniform of a soldier or a policeman. Fourth Material and craft of button show one's economic position. The button gives a Very good picture of what one's life was then. Precious button with gold, silver, and other jewels is an index to one's property. Fifth, The button of political event is used for election, which shows the face and the name of runner. Besides that, there were buttons designed for the flag or the slogan for political event. Sixth, The button of social event reflects a social phase of life in war or revolution, for example, it satirizes the burning of the Bastille in the French Revolution, or the taxpayer bearing the burden. Seventh, the buttons that symbolize a historic event are made to commemorante an epochal and critical occurrence or an important person's birth, death, visit to some place, etc., Eighth, there were well-known persons, for example, a president, a king, a queen, a singer, or an artist in the buton of personality. Nineth, The button of one's company shows one's community in figures or pictures, that is, this button is used as a symbol one's community. Tenth, The button varies with the development of science and technology. It gives a very good picture of what it was and what the technological level was. Eleventh, The buttons that symmbolize on occupation most impressively are uniform buttons. Symbolic marks related with a particular occupation are carved on the buttons of compary employees' uniforms. Twelfth, Various natural phenomena are designed to appear on buttons, Some express themselves simply as they are, and others appear as a symbolic form such as environmental relationship between men and nature, four seasons, a constellation and all other natural things occurring during a year. Finally, The button of rebus is a motto expressed by a combination with objects figures, letters, words, or phrases.

  • Ancient metal objects with inlaid designs were mainly decorated using the wire inlay technique in which "V"- or "U"-shaped grooves were cut in a metal object and then filled with gold or silver. Previous studies on ancient metal objects featuring wire inlay generally attempted to ascertain the inlay techniques applied by examining photomicroscopes acquired during conservation treatment. However, they had limitations when examining wire inlay technique to the minute details. Wire inlay technique can be better investigated by enlarging X-ray films of relics using stereoscopic microscopy under transmitted light. The core processes of the wire inlay technique involve cutting grooves using a chisel and creating the inlay wires, but researchers hold varying opinions about the two processes. This study analyzed the entirety of the materials able to shed light on the main processes applied in Baekje wire inlay by examining X-ray films of relics through stereoscopic microscopy. This exhaustive research revealed that two types of techniques were used for wire inlay during the Baekje period. One is a plastic process of engraving dotted lines using a chisel and is found mostly in objects from the Cheonan and Gongju areas. The other is a cutting process that incises fine lines and was used mostly in relics from the Osan, Seosan, and Wanju areas. It is likely that the Baekje wire inlay techniques feature regional differences because the respective techniques were used or introduced by different groups of people.

  • For the newly approach of policy with the old aged era at hand, the result which examines the 1,200 students attending professional colleges and upward in three small-to-medium sized cities, for two months, from October 1, 1996 to November 30, in order to know the change of consciousness of the growing modern young intellectual age group is as follows. 1. The objects of survey consist of 72.1% of women, 40.4% of 20 to 21 age, 49.1% of atheists, and people from big cities and fishing and agrarian village occupy equally 40.2%. Concerning the long-termed residents, 49% of them dwell in big cities. In case of the parents' age is more than 55, 31.5% in fathers, and 10.9% in mothers. 2. The types of housing in which they desire to reside in their getting older are : 72.8% of them hope to live in individual houses, 16.6% in apartments or villas, and 3.4% in social welfare facilities. Out of respondents, compared with other groups, man rather than woman, those who are 20 to 21 age group and from fishing and agrarian villages and have over 7 family members and live with their parents have a higher preference for independent houses. 3. The districts in which they hope to live when they are old are : 41.6% of them, with the highest percent, hope to live in farming villages, the older they are, the more they hope to live in agricultural district, and women of 21 years and upward hope to live in big cities. On the other hand, the preferable degree for social welfare facilities is higher each in people who are 24 years and upward, buddhists, self-boarding students, and the more poorly they are off, the higher the percent is. 4. The types of preferable welfare facilities for the elderly are : 58.2% of them think silver towns desirable, 28.4% think the charged (or free) elderly welfare facilities. Compared with other groups, the percentage which prefer silver towns is higher in women, people from big cities, residents of main family, long-termed city residents, people with higher income, people having grandparents alive, and people who had experience of taking lectures on hygienics or social welfare. 5. 50.3% of the respondents insist that provision of living expenses against old age should be insured by social security system, and 42.8% by the elderly themselves. The percentage of the former shows higher in people of 21 years and upward, women, residents of fishing and agrarian villages, christians, people in more needy circumstances and people who have experience of using a medical institution. 6. Compared with other nations, 54.5% of the respondents have an opinion that elderly welfare and welfare work in Korea stays in insufficient level and most of them are women, people from farming village, residents of head family, people having younger parents and people being worse health condition, and they have a more positive attitude about the elderly welfare work. 7. 92.3% of the respondents answered that a national budget for the elderly welfare is scarce, and the percentage is higher in people who are older, residents of big cities, people in lower living condition and people in worse health condition. 8. 35.2% of the respondents answered that the proper cost of their old age must be over 220mi11ion. The more a family's total income is, the higher the percentage is. 9. The factors which have an effect on the preference of silver towns are sex(p<0.01, the type of the present residence(p<0.05), and a family's total income(p<0.05). 10. From the survey result of the above, we comes to the conclusion that, for the sake of welfare of the increasing elderly population, government authorities and parties concerned must exert their utmost for the elderly welfare by increasing a budget of it and establishing a number of facilities of the elderly welfare and silver towns located in fresh and comfortable villages. In addition, they have to set up a course of hygienics in all the colleges and instruct the contexts on hygienic welfare as well.
