The CRT(Cathode-ray Tube) of salvage is a process of separating the panel and funnel to recycle a cathode-ray tube. In this paper, the thermal properties of glass for CRT were studied to improve its recycling ratio. In the salvage process, several patterns of breakage, as called 'comer pull', were easily generated on the sealing surface of panel or funnel glass due to the residual tensile stress, which had correlations with some parameters of the manufacturing process of CRT and the initial material properties of glass. Finite element analyses and experimental approaches on the flit sealing process were carried out to obtain the major characteristic of glass related to the residual stress. From this study, it was identified that the thermal expansion coefficient of glass had much influence on the residual stress of panel glass after frit sealing process. Therefore, the optimal conditions of thermal properties for CRT glass were proposed to achieve an effective salvage process. By using these optimal conditions, the size of comer pull on the panel and funnel glass was reduced to 10% level compared with the original size, and the recycling ratio of CRT was increased in the salvage process.

The air circuit breaker (ACB) with the spring-actuated mechanism was studied to improve the fatigue-proof<br/> characteristics of its link. The low-cycle fatigue fracture phenomenon occurred on the critical link, called h-link, of ACB from the repeated rapid closing and opening operations. To analyze the cause of failure, dynamic FE-analysis on the h-link part of ACB was performed considering the velocity and acceleration of the links per time as boundary conditions, which were obtained by using ADAMS. Also, the S-N curve obtained by experiments was used to investigate requirement on the fatigue-proof characteristics. Then, to reduce the maximum tensile stress on the h-link, three types of h-link were examined and one of them was selected.

This paper is a comparative analysis on the ancient music score and sound source of the Mongolian Buddhist song, Gur Duu. For the comparative analysis, this paper used the ancient music score from 1897 owned by Aimag Folk Museum at Bayankhongor, Mongolia and transcribed the staff by using the sound source recorded in 1979 with the same title, ‘Tsagaan dara ehiin zalbiral’, owned by Institute of Language and Literature, Mongolian Academy of Science. The manuscript from 1897 includes total of 64 Gur duu pieces and each piece is divided into 3 keys of upper key, lower key, and Chakhar. ‘Tsagaan dara ehiin zalbiral’ Gur duu analyzed in this paper falls under the upper key of 10-string yatgalig. The register for ‘Tsagaan dara ehiin zalbiral’ Gur duu in the manuscript covers from the low octave sol(g) to higher octave la(a) in fa(F) major. Meanwhile, ‘Tsagaan dara ehiin zalbiral’ in the recorded sound source is do (C)major and its register covers from low la(a) note to high do(c) with 10 intervals. In the ancient music score of ‘Tsagaan dara ehiin zalbiral’ Gur duu, the ancient music score was composed of 6 limes while the recorded sound source included 8 phrases. Each song was sang in both closed and open sets. In the comparative analysis on the ancient music score and sound source that were preserved in the form of written record and oral tradition with 100-year gap, the ancient music score and sound source showed the same key while involving difference in melody and lyrics. It is assumed that the beat got faster over time. This study holds significance in comparing the written tradition and oral tradition by using the ancient music score and sound source.

본 연구에서는 스탬프와 레진의 접촉-인장 방법을 이용하여 고 세장비를 가지는 폴리머 마이크로 헤어를 제작하는 공정을 제안하였다. 또한 광경화시 수축방향에 따라 마이크로 헤어에 표면주름이 다르게 생성되는 것을 실험적으로 관찰하였으며, 헤어의 직경이 20 μm 부근일 때, 일정한 패턴을 가진 표면주름이 제작되었다. 이 직경에서 스탬프와 레진의 접합력 보다 수축력이 더 크게 되어 광경화 도중에 레진이 스탬프에서 분리되면서 단방향의 수축을 유도하게 되어 일정한 간격의 주름이 발생하는 것으로 사료된다. 본 연구의 기초결과를 이용하여, 향후 균일한 표면주름을 가지는 다양한 형태의 마이크로 폴리머 헤어를 제작할 수 있을 것으로 사료되며, 생체모사, 열전달 및 촉매 촉진과 같은 표면적과 관련된 기술 등 다양한 분야에 응용이 가능할 것으로 사료된다. We proposed a new process to fabricate a highaspect- ratio microhair having surface wrinkles using the contactand- tension of a microstamp. Through this work, we observed that regular surface wrinkles were generated on the hair with a diameter of around 20 μm due to the uni-directional compressive stress during the photocuring process by ultraviolet light. To do this, we conducted an experimental system setup for contactand- tension process. From the preliminary test results, we believed that the proposed method can be applied to make a long polymer hair having surface wrinkles for special applications to biomimetics, and some research fields related on surface area such as heat transfer and catalyst enhancement.

Experimental studies on the fabrication of sub-30 ㎚ nanofibers using weakly two-photon induced photopolymerized region have been carried out. For the generation of nanofibers inside or outside microstructures, an over-polymerizing method involving a long exposure technique (LET) was proposed. Such nanofibers can find meaningful applications as bio-filters, mixers, and many other uses in diverse research field. A multitude of nanofibers with a notably high resolution (about 22 ㎚) in two-photon polymerization was achieved using the LET. Furthermore, it was demonstrated that the LET can be employed for the direct fabrication of various embossing patterns by controlling the exposure duration and the interval between voxels. Thin interconnecting networks are formed regularly in the boundary of the over-polymerized region, which allows for the creation of various pattern shapes. Overall of this work, some patterns including nanofibers are fabricated by the LET.

A subregional slicing method (SSM) is proposed to increase the nanofabrication efficiency of a nano-stereolithography (NSL) process based on two-photon polymerization (TPP). The NSL process can be used to fabricate 3D microstructures via the accumulation of layers of uniform thickness; hence, the precision of the final 3D microstructure depends on the layer thickness. The use of a uniform layer thickness means that, to fabricate a precise microstructure, a large number of thin slices is inevitably required, leading to long processing times. In the SSM proposed here, however, the 3D microstructure is divided into several subregions on the basis of the geometric slope, and then each of these subregions is uniformly sliced with a layer thickness determined by the geometric slope characteristics of each subregion. Subregions with gentle slopes are sliced with thin layer thicknesses, whereas subregions with steep slopes are sliced with thick layer thicknesses. Here, we describe the procedure of the SSM based on TPP, and discuss the fabrication efficiency of the method through the fabrication of a 3D microstructure.
