The aim of this study was to compare two formulations of film-coated pellets containing clarithromycin after single oral dose study in healthy male volunteers. Two formulations with different coating polymers were prepared: formulation-1 (F-1) was prepared by incorporating three kinds of pH-dependent gradient-release coated pellets into capsules and formulation-2 (F-2) was prepared by coated with an insoluble semiosmotic film. Release profiles of filmcoated pellets were evaluated using paddle method under different conditions. Pharmacokinetic profiles of these formulations were obtained in three healthy male volunteers and compared to commercially available immediate release (IR) tablets. The relative bioavailability based on the AUC0-24 h was found to be 96.2% and 58.7% for F-1 and F-2 compared with IR, and the Tmax was delayed.
Numerical Simulation of Flow Patterns in Cyclones of Different Cone Dimensions
Xiang, Rong B.,Lee, Ken W. WILEY‐VCH Verlag 2005 Particle & particle systems characterization Vol.22 No.3
<P><B>Abstract</B></P>10.1002/ppsc.200500946.abs<P>This paper presents the numerical simulation of the flow patterns within three cyclones of different cone dimensions. The simulation was performed with commercial CFD package FLUENT V5.5. The accuracy of the simulation was tested by comparison with the available experimental data. Simulation results show that the cone dimension significantly influences the flow pattern within cyclones. The comparison of the flow patterns within the cyclones of different cone dimensions explained well the different separation behavior of these cyclones. The results suggest that the CFD simulation is capable of predicting changes in flow patterns resulting from cyclone configuration modification.</P>
A New Approach for Modeling and Computation of Dynamics of Robots Containing Closed Chains
Xu,Xiang-Rong,Ma,Xiang-Feng,Choi,Young-Hyu,Chung,Won-Jee 창원대학교 공작기계기술연구센터 1999 연구업적집 Vol.1 No.1
This paper presents a new recursive algorithm of robot dynamics based on the Kane's dynamic equations and Newton-Euler formulations. Differing from Kane's work, the algorithm is general-propose and can be easily realized on computers. It is suited not only for robots with all rotary joints but also for robots with some prismatic joints Formulations of the algorithm keep the recurrence characteristics of the Newton-Euler formulations, but possess stronger physical significance. Unlike the conventional algorithms, such as the Lagrange and Newton-Euler algorithm, etc, the algorithm can be used to deal with dynamics of robots containing closed chains without cutting the closed chains open. In addition, this paper makes a comparison between the algorithm and those conventional algorithms from the number of multiplications and additions.

The aim of this study was to compare two formulations of film-coated pellets containing c1arithromycin after single oral dose study in healthy male volunteers. Two formulations with different coating polymers were prepared: formulation-1 (F-1) was prepared by incorporating three kinds of pH-dependent gradient-release coated pellets into capsules and formulation-2 (F-2) was prepared by coated with an insoluble semiosmotic film. Release profiles of filmcoated pellets were evaluated using paddle method under different conditions. Pharmacokinetic profiles of these formulations were obtained in three healthy male volunteers and compared to commercially available immediate release (IR) tablets. The relative bioavailability based on the $AUC_{0-24h}$ was found to be $96.2\%\;and\;58.7\%$ for F-1 and F-2 compared with IR, and the $T_{max}$ was delayed.

이 논문은 Kane의 동역학 방정식에 기초한 로봇 동역학의 새로운 循環 알고리즘을 제시한다. 이 알고리즘은 Kane의 동역학 방정식과 뉴톤-오일러 공식을 이용하여 얻어진다. 라그랑지-오일러(L-E)와 뉴우톤-오일러(N-E) 등과 같은 전통적 알고리즘과는 달리, 제안된 알고리즘은 간단하면서 確然하고, 閉체인을 그대로 포함된 로봇의 동역학을 푸는데 사용되어진다. 또한 이 알고리즘은 循環형태로 표현되어서 컴퓨터상에 구현하기 쉽기 때문에 로봇의 CAD(Computer0Aided Design)에 적합하다.

본 논문은 로봇 매니퓰레이터의 운동학적 탄성동역학 해석을 위한 새로운 방법을 제시한다. 분산 매개변수 방법에 기초하여 유연한 링크를 갖는 로봇 매니퓰레이터의 일반적인 운동 방정식을 유도하였다. 운동방정식의 결과식은 비선형 강체와 탄성운동 커플링 항을 갖는 일반 복합탄성 매니퓰레이터를 모델링하는 데 사용되어질 수 있다. 본 논문에서 제안된 방법은 계산적으로 효과적이며 로봇 매니퓰레이터 및 공간메커니즘의 유연성 해석에 이용될 수 있다.
