The purpose of this research was to examine the significance of the first edition of Tripitaka Koreana. In this research, the following were done: 1) by clarifying the place and date of praying for the engraving of the first edition of Tripitaka Koreana, its significance as "Daejanggyeong" produced to expel the Kitan was more clearly explained; 2) its physical characteristics were examined to provide evidence of the artistic and creative features of its engravings, quite different from those of the Gaebo Tripitaka made in China; and 3) its structure was analyzed from a viewpoint of a systematic bibliography. It was found that since the first edition of Tripitaka Koreana contained all the earlier lists of Buddhistic scriptures in China(and individual scriptures were thoroughly examined and included into its content since the reign of King Munjong), it had a systematic bibliographical significance demonstrated by its comprehensive and cumulative nature.

In most RP processes, the inherent stair-stepped surfaces and shrinkage-induced warping of the parts require post processing such as surface finishing. To minimize such defects, VLH-ST, a newly developed RP process, employs a 3.9-mm thick expandable polystyrene (EPS) foam sheet and a hot wire to contour it to have slant linear-interpolated sides. The use of relatively thick sheets for layers, however, limits the process capability of constructing fine details, especially smaller than the layer thickness. This study is focused on the development of a post processing method fo fine details of VLM-ST parts. The post-processing tool was designed to meet all the requirements for the desirable post processing. It adopted a hot wire as a means of melting the EPS foam sheet. Various basic experiments on the post processing were carried out to obtain the optimal process conditions. The dominant process parameters such as the radiated heat input, the tool speed, and the gap between the tool tip and the foam sheet (tool height) were considered in the experiments. The effectiveness of the developed post-processing method fo forming or engraving fine details on the VLM-ST parts has been thus demonstrated. The experiments on engraving several sets of letters, such as CANESM, 인간, and 한국과학기술원, on the EPS foam sheet were carried out. In addition, a flowery shape was engraved on a three-dimensionally curved surface of a pottery-shape VLM-ST part.

This study attempts at the engraving place of wood-printing plates held in the Haein Temple(해인사), which were famous for playing the significant role in the understanding of publishing activities of both the Koryo and Choson Dynasty. Following the common way the bibliographic elements of the books were analyzed namely according to the publication place and the publisher. The findings derived from the analysis are summarized as follows; In the Haeinsa the wood-printing plates books are preserved moved from 17 temples such as Bongso-Sa(봉서사), Hago-Sa(하고사), Soksuam(석수암), Inhung-Sa(인흥사), Wonkwang-Sa(월광사), Sinha-Sa(신하사), Gunsyaeng-Sa(군생사), Jangsu-Sa(장수사), Yongtong-Sa(영통사), Wonjok-Sa(원적사), Unjin(은진) SSanggye-Sa(쌍계사), Songsan(성산) SSanggye-Sa(쌍계사), Hungyul-Sa(흥률사), Jongwon-Sa(정원사), Yon-Sa(연사), Gamro-Sa(감로사), Yongguam(영귀암) besides the publications of temples, there are publications of local branches of gangyengdogam(간경도감) such as Jinju(진주), Sangju(진주), Sangju(상주), Andong(안동), of local public agencies such as Gaelimbu(계림부), Dalsunggwan(달성관), and of private families of which 8 titles in the Koryo Dynasty and 13 titles of the Choson Dynasty. Among the "SSanggyae-Sa(쌍계사) publication" held in the Haeinsa, 9 titles including Chimungyonghun(치문경훈) are recklesaly preserved with dividing both in Gap temple(갑사) and in Haeinsa as the same publication. It is possible that other scattered present publications or remaining publications might have been remaining publication from those partly burnt ones of the complete publications. By means of the investigation on the catalogs of publications, 5 titles such as <> <> <> <> <> which are now kept in the Haeinsa moved from the Taegubu(대구부) or Yongyon-Sa(용연사) were newly identified.

This study was intended to academically redefine the art of seal engraving of the Joseon Dynasty through seal analysis related to Kim Jeong-hui and to widely promote its excellence. Previous studies on seals were examined, and comparative studies were conducted focusing on the seals engraved by Kim Jeong-hui and the related seals. The importance of the real seal study, not the stamp, was confirmed. If there was a byeongwan on the side of the seal, it was possible to understand that Kim Jeong-hui directly carved the seal. Also, it was possible to confirm the stone quality of the seal, the method of writing, the method of layout, and the method of holding graver. The imitation seal engraved with a tool rather than hand made it easy to grasp the uncertain production intent. All were analyzed by actual tensile, so it was a possible study result. The results of this study will serve as an indicator to judge the authenticity of the seal when evaluating an ancient painting in the future.

This paper presents research on furniture making based on Hojangjul, which is an engraving technique that highlights the wooden patterns of traditional furniture. Somokbang, one of the 12 workshops in Tongyeong, has used Hojangjul as an engraving technique since Imjinwaeran. It was inherited by the late Cheon Sang-won, who was No. 59 of National Important Intangible Cultural Properties, and developed into Samhojang, Ohojang, Seongtoinoimun, Hotguinoimun, and Gyeopguinoimun. It was then spread to Masan, Ulsan, and Gwangyang via marine routes and further into the inland areas via land routes, developing in various patterns and forms. The present study investigated and examined the making techniques and characteristics of Hojangjul engraved in joinery furniture in Tongyeong, Masan, and Ulsan in the Gyeongsang region and Gwangyang and Dongbok in the Jeolla region, thus shedding new light on the traditional techniques that have been gradually disappearing and promoting the transmission, inheritance, and development of the traditional techniques.

A joint brand of furniture companies named Gaboro has been officially launched in the form of a juridical foundation. It was invested by Seoul City and the union members for regenerating the furniture companies in Seoul on August 1, 2003. However, Gaboro still has a few problems to overcome for successful business from joint marketing. Firstly, Gaboro must create a R&D post in order to lead the member companies through consistent production of furniture in addition to engraving its brand. Secondly, the head office of Gaboro must be authorized to prevent each union member from manufacturing the furniture products not well suited to the fresh brand. In addition, the member companies justly need to regulate the product items, and simultaneously to accept the new image concepts. Lastly, Gaboro needs to launch unique items to discriminate its design from other competitive companies.

By the specific character of femtosecond laser controlled volume of magnitude of micrometer scale could be ablated without melting phase in SKD11 and SUS304. According to the laser machining parameters various sectional shapes could be engraved on the surface of metals. Typical engraved lines were $10{\mu}m$ wide and deep. Coarse-milled surface was made $10{\mu}m$ lower than the original elevation by a bunch of laser-engraved lines in suitable spacing. The repeated banks with a height of $10{\mu}m$ could be made with the combination of the intact area.

The structural stress and vibration analysis of the rotary screen are investigated. The mechanical properties of the rotary screen, this is, Young's modulus and density of nickel alloy are determined experimentally. The natural vibration characteristics of the rotary screen are evaluated and the displacement, the stress of the rotary screen under the various load conditions are also examined. The radial displacement of the rotary screen is obtained by experiment under various rotating speeds.
