The purpose of this research is to examine the relation between the cyber environment and the contemporary fashion design by studying the formative feature characteristics of cyber character's fashion in the on-line game from the point of the contemporary fashion design. The research method is to understand the general concept of the cyber-space and characters and then is to contemplate characteristics and formative features of game character's fashion of the cyber-space mainly with cyber characters that were closely linked with features of the contemporary fashion design. As a result, the formative feature of game character's fashion of the cyber-space was to be classified into four categories; reactionism, mechanism, futurism, sensualism. First, reactionism takes traditional elements with symbolical and compromising form. Second, mechanism has a tendency of deconstruction due to its vitality and sense of velocity for objects through employing geometrical forms and new materials. Third, futurism deviates from the established framework. It makes use of high-tech materials and has surrealistic and futuristic features. Fourth, sensualism does emphasize sensual parts of the body and intends to convey aesthetic atmosphere through association of ideas. Character's fashion of the cyber on-line game is unnatural and artificial in its forms and wear for the lack of knowledge for costume's structure, and it shows just simplified design that accept extremely partial fragment of features in the contemporary fashion design.

The Characteristics of the flowfields of a square prism having a small square prism were investigated by measuring of lift and drag on the square prism and visualizing the flowfield using PIV. The experimental parameters were the width ratios(H/B=0.2~0.6) of small square prisms to the prism width and the gap ratios (G/B=0~3) between the prism and the small square prism. The drag reduction rate of the square prism initially increased and then decreased with the G/B ratio for the same H/B ratio, and increased with the H/B ratio for the same G/B ratio. The maximum drag reduction rate of 98.0% was observed at H/B=0.6 and G/B=1.0. The lift reduction rate of the square prism was not affected by the width and gap ratios; the total average value was approximately 66.5%. In case of a square prism having a small square prism, the stagnation regions were represented in the upstream and downstream sides of the square prism.

전자기기 패키징이란 광범위한 분야이므로, 전기공학, 전자공학, 기계공학, 재료공학, 화학공학 그리고 기본적인 물리, 화학 등의 모든 분야가 공동으로 참여해야 할 종합기술이다. 이 글에서는 종합기술인 전자기기 패키징 분야에서의 필요한 기계기술을 간단한 반도체 칩 패키징 분야에서 부터 시스템 패키징분야까지 소개함으로써, 현재 국내에서는 일종의 시작단계인 패키징분야에 여러 분야, 특히 기계공학도의 주의를 환기시켜 적극적인 참여를 권유하는데 있다.

Purpose: As the esthetic demands of dental implant patients are increased, the demands of zirconia as implant abutment material are also increased. It has non-metalic color, good biocompatibility, high strength and high toughness. Even thought the advatage of zirconia abutment, there are a few studies about mechanical properties of zirconia abutment. This study evaluated the mecanical strength with compressive bending strength and endurance limit of implant-zirconia abutment assembly. Materials and Methods: Static and cyclic loading of implant-Zirconia abutment assembly were simulated under worst case condition according to ISO. Test groups were implants of external butt joint with straight regular diameter and angled regular diameter zirconia abutment, implant of external butt joint with narrow straight diameter zirconia abutment and implant of internal conical joint with straight narrow diameter zirconia abutment. All test group were evaluated the mecanical strength with compressive bending strength and endurance limit. After fatique testing, fracture surface were examined by SEM. Results: The compressive bending strengths exceed 927N. Regular diameter zirconia abutment were stronger than narrow diameter zirconia abutment(P<.05). The endurance limits ranged from 503N to 868N. Conclusion: Within the limitation of this study, zirconia implant abutment exceeded the estabilished values for maximum incisal biting forces reported in the literature.
