Insert type 총형공구 여유각 영향에 따른 베어링 Rubber Seal 금형의 가공성 평가
Li, Li-Hai,김연술,김도형,양균의,문상돈 한국공작기계학회 2004 한국공작기계학회 춘계학술대회논문집 Vol.2004 No.-
Formed insert type tool satisfy both the surface roughness and geometric accuracy, so that cutting edge of formed tool can duplicate final feature. For experiment, the formed tools with various clearance angles are machined. And the tools are evaluated with respect cutting force, flank wear and surface roughness to optimistic condition.
Geometrical Compensation of Injection-Molded Thin-Walled Parts in Reverse Engineering
Yeun Sul Kim,Hi Koan Lee,Jing Chung Huang,Young Sik Kong,Gyun Eui Yang 한국정밀공학회 2005 International Journal of Precision Engineering and Vol.6 No.2
A geometric compensation of thin-walled molded parts in reverse engineering is presented. Researches in reverse engineering have focused on the fitting of points to curves and surfaces. However, the reconstructed model is not the geometric model because the molded parts have some dimensional errors in measurements and deformation during molding. Geometric information can give an improved accuracy in reverse engineering. Thus, measurement data must be compensated with geometric information to reconstruct the mathematical model. The functional and geometric concepts of the part can be derived from geometric information. LSM (Least square method) is adopted to determine the geometric information. Also, an example of geometric compensation is given to improve the accuracy of geometric model and to inspect the reconstructed model.

This study in aim at observing and comparing the correlation between reaction time and power selected 53 ball game players(Foot ball, Hand ball, Rugby foot ball), 48 match event players(boxing, wrestling, Tae kwon do) and 39 track and field athletes (Broad Jump, High jump) as subjects. The results of this study are as follows. 1) High jump players are the most fast in anditary and optional reaction time (0.41sec). 2) Auditory reaction time is more faster than optional reaction time in all athletic events. 3) High Jump athletes are the highest in power(56.3cm), on the other hand, throwing athletes are the lowest in power(48.2cm). 4) There are significantly correlation between reaction time and power in high jump players(R=0.70∼0.78) on the other hand, match event has not correlation between reaction time and power(R=0.17-0.38).

원발성 담즙성 간경변증은 원인 미상의 담즙정체 질환으로 만성적인 간내 담관의 염증을 보이면서 간경변증으로 진행하는 드문 질환이다. 저자들은 황달과 소양증을 주소로 내원한 55세의 여자 환자에서 원발성 담즙성 간경변증 1례를 경험하였기에 문헌고찰과 함께 보고하는 바이다. Primary biliary cirrhosis is rare and a disease of unknown origin. It is a chronic cholestatic liver disease characterized by the presence of chronic inflammation, necrosis of hepatic bile duct and progression to liver crirhosis. We experienced a 55 year- old woman complained of jaundice and itching for 3 years. Her clinical symptoms, biochemistry, liver function test and liver biopsy were compatible with primary biliary cirrhosis. Thus we report a case of primary biliary cirrhosis with literature review.
