The management of return flows induced by the various forms of reuse of products and materials in industrial production processes has received growing attention throughout this decade. As one of the developing countries in the world trade market, we have to apply the reverse logistics system considering an environment seriously, and to implement reverse logistics activities abreast with the forward logistics system of a companies. Therefore, the objective of this study was to discuss what the reverse logistics system of Environmentally Conscious Logistics Systems(ECLS) is by introducing a case study.

Reverse Engineering is to find CAD model through measured data of a physical model which is not available in CAD model. The measured data are obtained from measuring with Coordinate Measuring Machine or Laser Scanner. This paper introduces efficient methods of reconstruction through the applicating process of the Reverse Engineering with technical surfaces.

This paper is to develop of 3D reverse engineering equipment. The existing equipment didn't use in the field popularly as it is too expensive. So in this study, we build the reverse engineering system of simple construction using a LM guide and a laser sensor. Therefore we measured product using this equipment, this result compared with the CAD date.

This paper is the performance evaluation of reverse engineering system using simple mechanism. The existing equipment didn't use in the field popularly as it is too expensive. So we constructed the reverse engineering system of simple mechanism using the laser sensor, LM guide, micro step driver and control program. And we caught the Characteristics to measure some product. Finally we confirmed the precision to compare measured data and CAD date.

In this article, we first give the $L^p$ boundedness of the operator $D^2L^{-1}$ with BMO coefficients and a potential V satisfying an appropriate reverse $H{\ddot{o}}lder$ condition, then obtain global $W^{1,2}_p$ estimates for the nondivergence parabolic operator L with VMO coefficients and a potential V satisfying an appropriate reverse $H{\ddot{o}}lder$ condition.

An approach to identifying input forces is proposed using measured structural dynamic responses and its analytical model. The identification of input forces is a reverse process and ill-conditioned problem. Its solution is unstable and generally case dependent. In this paper, the ill-condition is described considering characteristic matrix which is defined by reduced dynamic stiffness matrix. Special attention is focused on the condition number of a characteristic matrix used in the solution algorithm of this reverse process. Simple example is presented in support of the ill-condition of a reverse process.

항시 장착이 가능한 reverse twin block 장치에 기능의 장애를 받지 않고도 lip pad의 효과를 첨가하기 위하여 가철식으로 lip pad를 제작하여 III급 부정교합의 치료에 적용해 본 결과 다음과 같은 결론을 얻었다. 1. Reverse twin block 장치는 장착한 상태에서 lip pad의 착탈을 통하여 정상적인 저작, 발음 등의 기능을 할 수 있으며 심미적이므로 III급 부정교합의 치료에 있어 상하악이 분리되어 있지 않은 다른 기능성 장치가 가진 단점을 극복할 수 있었다. 2. 본 증례에서는 저발육된 상악에 대한 효과적인 작용을 하는 lip pad를 가철식으로 제작하여 기능의 장애를 받지 않고도 양호한 치료효과를 얻을 수 있었다.
