Considering the current rise in elderly population, institutions and facilities caring for the elderly are currently unable to satify the growing needs of the aged wanting the better qualities of life. Therefore, this study will analyze institutions and policies for the elderly in Japan, which has already experienced the rise in elderly population about 30 years earlier than Korea. Because the living conditions of Japan is somewhat similar to that of Korea, analyzing its solutions, both governmental and private, will help better understand the current situations of Korea and possibly offer guidelines as to better serve the growing demands of the aged. In Japan, the social welfare policies directed at caring for the elderly are mainly directed by the government: however, the private services tend to be more adroit at meeting the ever-changing demands of the elderly. Incidentally, the privately owned elderly homes of Japan are a major part of so called the "Silver Industries". The elderly home that are run by private corporations consititute 50 percent of all private institutions for the elderly. These homes tend tobe situated in a city, or near a city environment, serving 25 to 99 people. The types of such homes can be classified from A to D,E,F, reflecting the various services offered by such homes meeting the various demands by the elderly populatiov. Analyzing the social tred of Japan for theelderly, it can be said that the responsibility of the elderly should not only be relied upon the government, but to the society as whole, both public and private. The ever-changing demands of the elderly, wanting better qualities of life, can be better served by systematic analysis of the demands and the various solutions to such demands. Also, the necessary governmental policies in support of elderly welfare, will be needed.be needed.

This study reviewed pertinent literature and examined relics of manggon(a headband worn to hold a man's topknot hair in place), donggot(a topknot pin), and chigwan(a topknot cover). Before the modernized short hair style, wearing a gat was an important custom. Therefore, manggon, which was used to hold a man's hair in place under the gat, was considered an essential part of the man's official dress code. Donggot is a pin that held the topknot hair in place. It was a must have for a married man, like the binyeo, a lod-like hairpin, for a married woman. Unlike gwanja, it had nothing to do with official rank, but materials were of a variety of materials, including jade and gold. The structure of the donggot was studied in three parts-head, neck and body. Major forms for the head include the mushroom, bean and ball. Bullet and half-cut bullet forms were also found. Forms for the neck include straight-neck and curved-neck. A neck with a belt around a double chin was also found. Forms for the body include the tetrahedron, octahedron and cylinder. The most popular form for silver and white bronze donggot heads was the mushroom, followed by bean and pile forms. Chigwan is also called chipogwan, chichoal, choalgyesogwan, noingwan and sangtugwan. In poetry it was called chichoal, and it used to be called taegogwan in the past as well. Chigwan was so small that it managed to hold a topknot. According to confucian custom in the Joseon period, by wearing chigwan, men didn't display their bare topknot even when they didn't dress up. When they went out, they wore another official hat over the chigwan.

Modernization movement has affected classical operas. Today, classical operas are often re-interpreted from the modern perspective and played differently only with the storyline maintained. Also, operas are increasingly performed outside traditional theaters as the boundaries between stage and audience become less obvious. Accordingly, stage costumes are being differently designed than before. New attempts are being made to look costumes in a harmony with increasingly streamlined stage machinery. This helps increase public attention on operas, consequently promoting the opera industry. This study examines modernization of opera costumes. For this study, the author worked as one of costume design staff for "Faust," which was played in Sungnam Art Center from November 24, 2005 to November 27, 2005 in commemoration of the opening of the center. The following outcomes of the crowd are drawn from this study. A variety of splendid pink dresses, ribbons, dolls, hand mirror, and hair bands were used to express haughty girls with "Princess Syndrome." Fashion models, the envy of all woman, wore fashionable clothes including luxury dresses, fur-coats, high heels, purses, and hats, Models also had big shopping bags and gift boxes to symbolize shopping lovers in a modern society. Gay men wore tight leather trousers and vest and sleeves shirts with deeply cut neckline to express their preference for feminie style. their clothes were splendid colors that normally women liked such as gold, purple, light green, scarlet, and silver. Soldiers were in combat uniform representing their participation in the war. In particular, clothes stained with dirt, iron helmet, crutches, and canteens were used to vividly express soldiers coming back home from the war. Modern opera costumes now help reduce the time and space between stage and audience, improve economic efficiency, and meet the audience's needs for various style.

Flexible transparent conductive electrodes (TCEs) have recently attracted a great deal of attention owing to rapid advances in flexible electronic devices, such as flexible displays, flexible photovoltanics, and e-papers. As the performance and reliability of flexible electronics are critically affected by the quality of TCE films, it is imperative to develop TCE films with low resistivity and high transparency as well as high flexibility. Indium tin oxide (ITO) has been the most dominant transparent conducting material due to its high optical transparency and electrical conductivity. However, ITO is susceptible to cracking and delamination when it is bent or deformed. Therefore, various types of flexible TCEs, such as carbon nanotube, conducting polymers, graphene, metal mesh, Ag nanowires (NWs), and metal mesh have been extensively investigated. Among several options to replace ITO film, Ag NWs and metal mesh have been suggested as the promising candidate for flexible TCEs. In this paper, we focused on Ag NWs and metal mesh, and summarized the current development status of Ag NWs and metal mesh. The several critical issues such as high contact resistance and haze are discussed, and newly developed technologies to resolve these issues are also presented. In particular, the flexibility and durability of Ag NWs and metal mesh was compared with ITO electrode.

The purpose of this study was to grasp the consciousness of adolescents about their future in old aged housing. This research was executed with a questionnaire survey method. Data samples were collected from 255 students who finished first grade curriculum in high schools in Chonbuk province and Seoul city. The results were as followed. First, a healthcare plan was very highly recognized by students, and they wanted to live as couples or single in their old age. Second, the respondent students recognized elderly housing as a home for the aged, a silver town and nursing home. 72.1% of the respondents preferred a single detached house as an elderly house form. They preferred an elderly housing district with well provided convenient facilities for daily living. They wanted to live in the country or rest areas for the aged. They preferred an interior space composition with LDK with 2 bedrooms. 52.0% students wanted a neighborhood for their friends to live together. Third, 28.3% of the respondent students thought the appropriate time to move in elderly exclusive housing was 66-70 years old. And when their physical condition worsened or they needed care, they would. want to move into that housing. Also, they wanted the most convenient facility and a medical care facility in elderly exclusive housing. Forth, students' space design needs for elderly were high, more than 4 points. It was especially needed safety in space design, and this grade was 4.56(,53) points. Also the needs of safety and the convenient facilities.equipments were statistically significant by boys and girls.

The purpose of this study is to examine the interior textile color changes and trends by analyzing the characteristics of interior color hues and tones. Heimtextil in the interior field was selected for color trend analysis from 1996 to 2000. The conclusions of this study are as follows: First, In terms of hue, warm colors like Y, YR, and R were most prominent in all four years. Some new colors, however, emerged with higher frequency. The frequency of GY and B increased in 96/97, GY, BG and PB in 97/98 PB and B in 98/99, and B and PB in 99/2000. Especially between 96/2000, the frequency of PB and B has been increased, although the frequency of GY has been decreased. Over the four years, P, RP, and Neutral showed medium frequency, and G and BG showed low frequency. Gold appeared as an accent color in two years while silver appeared in one year. In summary, warm colors like Y, YR, and R were most prominent in interior color. Second, In terms of tone, p, b, v, and sf were most prominent over the four years. Although 에 and ltg appeared with high frequency n general, a wide variation was presented. The tones such as p, dp, and v appeared with high frequency in the three years of 96/97, 97/98 b and sf in 97/98 ; lt, dk and sf in 98/99. On the other hand, a new trend emerged in 99/2000. In this year, ltg, sf, s, d and dkg appeared with high frequency unlike the other three years. In other words, soft or light tones, such as pale, soft, light, grayish, and deep, and strong tones, such as vivid and bright, appeared with high frequency.

There have been many studies on the subject of risks in the Construction Industry and many useful results have been produced. However, risk studies on the conditions of contract, which is the most critical contract documents, has not been tried despite of its contractual function in the overseas projects. In this study, various contractual risks are identified for proper and reasonable evaluation of the contractual risks possibly encountered in the Tender and/or Contract stages of the Projects. For development of study, FIDIC Red Book 1999 Edition which is world widely recognised as a standard conditions of contract prepared for the projects designed by the Employer. Contractual risks are divided into three levels and applicable clauses are assigned to each appropriate risk factors. And table of major contractual risk factors are made using the classified levels of each factors with evaluation criteria as a result of this study. As this study is made only for the conditions of contract which is prepared for the construction contracts designed by the Employer, further studies for other types of contracts such as Design-Build (FIDIC Yellow Book), EPC/Turnkey (FIDIC Silver Book) and recently developed Design, Build and Operate type of contract (FIDIC Gold Book) are required to cover various types of projects executed in the world construction markets.

Ip-yeong or gat-keun decorate heuk-rip, supplementing its simplicity. When the wind blew, a dynamic beauty was created, especially if the gat-keun was made with long straps of jade or silk. Basically, ip-yeong was a practical chin strap to hold the gat tight on the head. Commoners made ip-yeong by folding cotton cloth or fine gauze. However, as available materials became diversified, people used cloth, jade, agate, amber, coral, gold medallion, rock crystal and bamboo as well, juk-yeong, which was made with bamboo, became popular especially when Heungsun Daewon-gun, the father of King Kojong, decreed that people wear simple clothes. Most records concerning ip-yeong in Chosun-wangjo-shillok, the authentic record of the Joseon Dynasty, are related to forbidding a sumptuous life. The book also suggests that ip-yeong was bestowed by the king or was offered to foreign diplomats as gifts. Ip-yeong doesn't seem to be a unique system for Korea. Based on portraits or paintings where ip-yeong can be found, it seems to have been widely used during the Yuan dynasty and the Goryeo dynasty. The system disappeared in China as the Ming Dynasty was established, but it remained in use in the Korean Goryeo dynasty and through the Joseon. Literature suggests that the same materials were used for ip-yeong from the beginning of Joseon to the end of the dynasty. Guyeongja refers to a ring that connects an ipja to a chin strap. Guyeongja made with silver, bronze and jade still remain. In gungjungbalgi, the royal court inventory book, records of imogarye can be found (1882), where ten pairs of pure gold strap rings and ten pairs of gold-plated ones were used for a royal wedding.

This study is a review of Ipsik, the decorative ornaments found on traditional Korean horsehair hats, known as Ipja, which were worn by men in the late Joseon Dynasty. In a broad sense, Ipsik are regarded as men's accessories. Therefore, although this study is limited to Ipja, it is significant in the sense that it delves into one facet of men's accessories in detail. Because the appearance of the horsehair hats was rather mundane, Ipsik and Ibyeong were added as ornaments. During the Joseon period, various types of hat ornaments existed, named Maeksu, Hosu, Gongjagu, Sangmo, Jingdori, Ijeon, Guyeongja and Ibyeong. A person's social ranking and class could be discerned by the materials used in the Ipsik he wore. Jeongja, a decorative accessory used to attach to an official's hat, was institutionalized in the sixteenth year of King Gongmin's reign(1367), during the Goryeo Dynasty, prior to the founding of China's Ming Dynasty in 1368, which indicates that Jeongja were influenced by the Yuan Dynasty. A record in Lao Chi'ta (a textbook of spoken Chinese estimated circa 1346) confirms this fact. Based on a review of literature, we learn that just as with Ongno, Jeongja were imported for use on Jeonrip, a soldier's hat. During the Ching Dynasty, Jeongja were further subdivided and more exquisitely designed. On the other hand, in the Joseon Dynasty, a rule was handed down mandating that a royal prince use gold for his jeongja, officials at third rank or above use silver, and governors, commanders in chief, and officials with the Office of Inspector General and Office of Censor General use jade. Inspectors were permitted to use crystal. Jeongja made of jade were used until the late Joseon Dynasty.

The master pattern manufacturing process is one of the most important processes in jewelry industry because the process takes 20% of total jewelry manufacturing costs. The previous jewelry manufacturing process has many steps of "rough design${\leftrightarro}$ detailed drawing${\leftrightarro}$ wax pattern manufacturing ${\leftrightarro}$ lime soda flask mold manufacturing ${\leftrightarro}$ silver master pattern manufacturing ${\leftrightarro}$ mass production of wax pattern ${\leftrightarro}$ investment casting process ${\leftrightarro}$ final jewelry product." A novel process that reduces processing steps by using a rapid prototyping system (RP) has been suggested. The process is "3D CAD design ${\leftrightarro}$ DuraForm mold manufacturing by RP ${\leftrightarro}$ manufacturing master pattern by low melting alloy ${\leftrightarro}$ mass production of wax pattern ${\leftrightarro}$ investment casting process${\leftrightarro}$ final jewelry product." Molds are made with DuraForm powder, of which melting temperature is 19$0^{\circ}C$, by a selective laster sintering type RP. An alloy of Pb-Sn-Bi-Cd, of which melting temperature is $70^{\circ}C$, is casted in the DuraForm molds. Spheres and rings of diameter 20 mm are made by this process. The dimension deformation rate is less than 2%, and the post processing of the castings is convenient. The casting made by the suggested process can be used as a master pattern of jewelry products.of jewelry products.
