  • Dual band internal antennas were fabricated with Ag conducting paste of various preparation conditions and different print thickness by silk screen print. We have investigated microwave properties were compared Ag conducting paste antenna with copperplate antenna at 800 MHz and 1,800 MHz. Gain of Ag conducting paste antenna was improved when preparation conditions were the single size Ag particle, using dry type resin and high Ag containing percent. However, it was lower than that of copperplate antenna within $0.1\~2.0dBi$ at 800MHz. In addition, it was improved at 800MHz when thickness of Ag conducting paste was printed more than skin depth but it was held after critical print thickness. On the other hand, it was reached level of copperplate antenna at 1,800MHz.

  • The word 'chintz' is thought to be a corruption of spotted cloth. Printing remained a relatively primitive method of decorating textiles in Europe until the second half of the 17th century. The formation of the English East India Company sparked the influx into the West of painted and printed Indian cotton textiles. A William Sherwin took out the first English patent in 1676. The earlist European designs were florals in the Indian manner. Patterns of European flowers returned to England as birds, flowers, trees, vines and stained glass for Victorian chintz. In France, the original and most successsful manufacturer of the distinctive printed fabrics from Jouy was Christophe Philippe Oberkampf. Copperplate printing was introduced to Jouy in 1770, probably reaching the pinnacle of achievement in the craft after 1783 when Jean-Baptiste Huet became chief designer. Huet's style was widely imitated in France and abroad, and the term 'toile de Jouy' has come to be universally applied to monochrome figurative designs wherever and by whomsoever they were produced. Oberkampf served his apprenticeship as an engraver with some leading manufacturers, including a period in Mulhouse. In Alsace, which was not part of France until 1798, the first factory had opened in 1746 in Mulhouse, and the area soon had the largest number of print-works in France.

  • Energy source of a piezo-electric harvester is vibration. Sources of vibration are machineries operated with high frequencies, constructions and people operated with low frequencies and etc. In this study, we tried to figure out power generation properties over vibrations upon angles of a piezo-cantilever for applying them to movements of the construction and/or people, which are vibration sources at low frequencies. A uni-morph cantilever with a $59mm{\times}29mm{\times}0.2mm$ piezo-electric element attached on a $71mm{\times}46mm{\times}0.25mm$ copperplate was used. A spring was attached to the lower side of the cantilever and a mass was attached on the opposite side. Also, a structure with a specific angle which is an angle in between the ground and the cantilever was prepared and then, connected to a spring or the cantilever. Then, this structure was divided into the A-type and B-type and excited in the direction of z- axis. After that, the angle between the ground and the cantilever was changed and excited by 1 to 10 Hz upon the existence of a spring and/or a mass to compare power generation properties.

  • 이 연구의 목적은 과거 서양에서 이루어졌던 예술과 기술, 과학의 융합 사례를 소개 하고 그 성공 요인을 점검하는데 있다. 연구에서는 16세기 네덜란드 안트베르펜에서 출판업을 수행했던 플랑탱 출판사가 화가들과의 협력 사례를 중심으로 분석한다. 플랑탱 출판사는 루벤스, 보르흐트 등의 화가들과 협력해 사업을 수행했고 결국 큰 성공을 거두었다. 이 협력 작업을 통해 화가들은 자신의 재능을 펼칠 새로운 매체를 발견하거나 아니면 그 재능의 가치를 높게 평가해주는 일자리를 확보할 수 있었다. 한편 출판업자는 혁신적인 기법을 도입하면서 경쟁사보다 수월하게 출판 시장을 점유해 나갈 수 있었다. 그리고 이러한 작업은 위대한 식물학 저술들의 출판이라는 결과도 낳았다. 17세기에 네덜란드가 식물학 연구의 중심지가 된 데는 정교한 삽화를 그려낸 화가와 그 지식을 효율적으로 구현해 낸 출판업자들의 숨은 노력이 있었다.

  • Tomb No. 1 (Donghachong) of the Buyeo Neungsan-ri Tomb complex (listed as UNESCO World Heritage Site), is a royal tomb of the Baekje Sabi Period. One wooden coffin unearthed there is an important relic of the funerary culture of the Baekje. This study examines the production techniques of gilt-bronze objects attached to the wooden coffin excavated from Donghachong. The base metal of the gilt-bronze object is pure copper, with single α phase crystals in a heterogeneous form containing annealing twins; Au and Hg are detected in the gilt layer. We suggest that the surface of the forging copperplate is gilded using a mercury amalgam technique; it is thought that the annealing twins of the base material formed during the heat treatment process for the sheet metal. The gilt layer is three to five times thicker for the gilt-bronze objects found near the foot of the coffin than those near the head. We estimate the plating process is carried out at least three times because three layers are identified on the plate near the head. Therefore, it is likely that the materials and methods used to construct the gilt-bronze objects found in different parts of the coffin are the same, but the number of platings is different. This research confirms the metal crafting techniques used in Baekje by the examination of production techniques of these gilt-bronze objects. Further, our paper presents an important example of restoration and reconstruction for a museum exhibition, through effective use of scientific analysis and investigation.

  • "Printing is an Art of reproduction & a Technique of However printing has extended its limitation from a genre of reproduction itself and now it stands on the turning point as an art such as painting or sculpture which expresses artist's originality. Early Printing has had relations in depth with press printing in terms of information recording, preservation, and transmission. It was acknowledged value in a way of information satisfaction different from how it is valued as a pure art today. But, later printing has transferred its function from a mean of reproduction to pure art due to the development of printing skills and photography invention. It can be said that the concept of modern printing is taking over its genealogy as a creative work not as just printing. Also its expression capability is widen to dimensional printing and high-tech multimedia from original tradition techniques. As we discussed above, modern painting is very open to various changes. This modern painting aspect can be seen as an extended interpretation of 'board' concept. This dissertation raises a question why monotype and monoprint couldn't secure its position in printing history in spite of numerous artists' tryouts in its way. Monotype and monoprint fundamentally based on intaglio technique in its history. Yet, its systematic study hasn't been worked out. This is because of the lack of recognition of monotype and monoprint's originality as printing. Especially in monoprint, it has known as an early stage in copperplate printing process which is an attempt to solve the technique limitation or trial work for edition. Likewise the reason why monotype and monoprint remains at the edge of printing border ambiguously is because of conceptual, technical characteristics which are against traditional printing. In traditional printing, the concept of board is important as a method of reproduction. Different from the fact, monotype and monoprint accept the form of medium 'board' conceptually out of limited condition as mentioned. Thus monotype and monoprint hasn't stand out for several reasons until late 20th century when it started come out to public as people starts to have interests that works from famous artists are actually based on monotype and monoprint. This dissertation likes to step into the monotype and monoprint theoretically which is not well known in domestic and try to study the meaning of monotype and monoprint as a printing medium which is also hasn't been considered sincerely. For this study the process follow as below. First, look into how monotype and monoprint has a concept and history. Next, check differences through comparison with traditional printing and how printing can be understood in what aspects at the same time. After, verify how monotype and monoprint have influence on the acceptance of extended concept of 'board'. This study will show the expressional possibility of monotype and monoprint which has already known as 'tableau printing' in today's situation where adventurous experiments of printing medium are going on with the development of technology.
