As tools for machining precision componants, end mills and ball end mills are widely used. For the end mills have longer cylindrical shape comparing dianeter, they are liable to deflect when machining and induce geometrical error and deterioration of surface roughness. To improve the stiffness and the sharpness of the cutting edge of end mill, a software for manufacturing end mills are developed. The program predicts the result of helical flute grinding and the configuration of cuting edge which is located in cylindrical surface. Furthermore to facilitate the manufacturing end mills using CNC grinding machine, the setting condition which satisfy the geometrical requirements like tool rake angle and stiffness are obtained.

The 21st century are seeing a large number of performing arts, and one of them, opera is evolving, transforming itself as one of total arts. Besides, the costume in performing art which play a major role in opera's visual impact, characterize figures, set the tone for performance and greatly contribute to the perfection of the stage. Under these circumstances, the study developed designs of stage costumes and built a full-scale production of the Magic Flute, one of three greatest Mozart operas. The opera based on a fiction, is still popular today since it is a fantastic fairy tale introducing moral and ethical lessons. The play's background itself is Egypt. But due to its fairy-take-like storyline, it has been performed focusing on various concepts rather than on costumes prepared through background research. As such, this study conducted research on designs of stage costumes that contains the element of Egypt and also take athleticism and comfort into consideration. The results derived from the study were as follows. First, traditional dresses of ancient Egypt were used as a basis while adding some modem touch in terms of forms or colors, which resulted in a new design. Second, a variety of images were captured using textures and colors that fit the characteristics of attributes of the figures. Third painting techniques were used to help highlight the symbolic image of Egypt-simple, not heavy and extravagant-with fairy-tale-like fantasy.

Defects of corrugated board were limiting factors to the corrugated industry's growth. On-line detecting systems of defects are beneficial to increase profits of the corrugated board companies by reducing base paper consumption, increasing process reliability, and increasing productivity. By replacing naked eye inspection of defects to a defects detecting system, continuous inspection without fatigue may guarantee final products quality. The system was developed, which was consisted of line scan CCD camera, lens, illuminating parts, high speed image processor, software, various input parts, and output parts. First installation location of the system was at before fluting process after base paper unwinding, and surface of liner board was inspected by the system. Second installation location was after fluting process and combining process for liner board. Production loss includes ragged appearance of edge, irregular flute shape, wrong combination of flute, score cracking, defects in base paper, and flute cracking. The production loss was analyzed before and after the system installation at a commercial domestic mill. The production loss ratio was defined as a production loss weight per total production weight. The production loss ratio before the installation was decreased a lot from 1.28%(during 3 months before installation) to 0.76%(during 12 months after the first installation) and to 0.25%(during 6 months after the second installation).

1964년부터 국악기의 현대화, 표준화, 과학화 등을 위해 국악기에 대한 연구와 개량사업이 추진되었으나, 국악기가 가지고 있는 고질적인 문제들은 큰 성과를 거두지 못하였다. 이러한 주요 원인중 하나는 국악기에 대한 악기 음향학 연구가 선행되지 못한 것으로 분석되고 있다. 국악기 중 협주곡이나 독주곡에서 사용하고 있는 소금은 맑은 음색과 높은 음역으로 인하여 국악관현악단에서도 서양 오케스트라에서의 플룻의 역할을 수행하고 있는 악기이다. 본 논문에서는 비슷한 음색으로 들리는 소금과 플룻의 음색을 악기가 가지고 있는 배음의 분포와 구조를 통해 분석하였다. 이를 통해 전체적인 음색은 소금에 비하여 플룻이 풍부하고 부드럽다는 것을 알 수 있었고, 고음으로 갈수록 배음들의 비슷한 구성으로 인하여 두 악기의 음색이 비슷하게 들린다는 것을 알 수 있었다. 추후에는 다양한 국악기들에 대한 악기 음향학적 연구가 지속적으로 수행되어 국악기의 대중화와 세계화에 작게나마 도움이 되길 기대한다.

The presence of the sound tube and resonance cavity is unique in Korea Brahman Bells which is no examples in other country bells in the world. The sound tube erected in the crown is effective to emit the fundamental tone of the bell when the condition of resonant transmissibility is satisfied. The results of our analysis shows that the optimum length of the sound tube in the Bell Emile is 96cm but is not the present length, 77cm. The resonance cavity erected underneath the lip of the Bell Emile is found to be for the resonance of standing waves in the space including both bell cavity and resonance cavity and resonance cavity to the fundamental tone of the bell itself, in order that the strongest vibration can last long by least energy and lengthen the reverberation of the bell. Some historical remarks are also made on the magic flute, MANPASIKJUK, which was in existence in Shilla that can lull all evil waves, such as plagues, storms, droughts, famines and even enemies. The sound tube erected in the crown of the bell was originated in this magic flute. Finally, a strong proposal is advanced on the new national symbol of Korean traditional cultural assets. Indeed, it should be highly recommended that the Great King's Bell Emile would be the only real symbol of our national cultural assets by its own right of excellency and richness in every aspect of arts and sciences.

자기 주도적 학습의 활용방안으로 음악 교육 분야에서는 전자 악기의 필요성이 높아지고 있다. 그러나 전자악기와 관련된 기존의 다양한 연구들과 상용제품들은 초등학교 저학년 학생들의 악기연주 자율학습에 활용하는데 어려움이 있다. 본 논문에서는 이러한 문제점을 해결하기 위한 방안으로 일반 PC환경에서 사용되는 블루투스를 이용한 전자 플루트 개발 방법을 제안한다.

The document archives like official documents, books, maps and historic paper artifacts are primarily based on the organic cellulosic materials. As the passage of time, these organic cellulosic materials are slowly deteriorated by various aging factors, like light, polluted air and biological fungi. Many researchers have been carried out the examination method of deteriorating origins, the mechanism of aging hysteresis, and the preserving method of archival materials. One of the most simple and easiest ways for conservation of organic archival documents is the proper storage under environmental control. Corrugated board for archival quality container has been developed and already used in advanced country, like Japan, USA, German, UK and Europe. In case of Korea, corrugated board for archival quality container has been used a decade ago, but totally imported. This study was tried to develop the corrugated board for archival quality container. Liner and corrugated medium were specially produced and finally manufactured to E flute corrugated board. The physical and strength properties of permanent base paper and corrugated board were evaluated, and compared with imported corrugated board. 4 kinds of corrugating adhesives were considered various in order to investigate optimum adhesive for flute development between liner and corrugating medium, and evaluate adhesion strength under conditions of storage and curing temperatures.
