Recently, foreign labor standards accreditation system has been emerged as more firms outsource manufacturing works to global vendors focused manufacturing. This paper discuss and compare three major private labor accreditation systems and evaluate what kind of problems may emerge if they become the major global standards for labor practices. This paper concludes that private labor standards accreditation system needs more transparency in the process and should improve accountability by including other stakeholders in the process.

In discriminant analysis the procedures commonly used to estimate the dimensionality involve testing a sequence of dimensionality hypotheses. There is a problem with the size of the test since dimensionality hypotheses are tested sequentially and thus they are actually conditional tests. The focus of this paper is to investigate in asymptotic sense what happens to the sequential testing procedure if the assumption of normality does not hold.

For the customer satisfaction, the inside customer satisfaction must be made by offering the service of a good quality to the inside customer. If the inside customer is not satisfied with own business, the achievement of customer's loyalty & customer satisfaction which have direct effects on the performance of a corporation, comes to be difficult. This study tries to analyze what effect the inside customer satisfaction has on the yield performance of a corporation on the subject of the salespersons of the direct-control store among the retail store business.

The mirror conjecture means originally the deep relation between complex and symplectic geometry in Calabi-Yau manifolds. Recently, this conjecture is posed beyond Calabi-Yau, and even to, open manifolds (e.g. $A_{n}$ singularities and its resolution) is discussed. While if we treat open manifolds, we can't avoid the boundary (in our case, CR manifolds). Therefore we pose the more precise conjecture (mirror symmetry with boundaries). Namely, in mirror symmetry, for boundaries, what kind of structure should correspond\ulcorner For this problem, the $A_{n}$ case is studied.

In this paper, we present a supervision and coordination level monitoring the adaptive controller and taking appropriate ,actions if malfunctions are detected. Supervision and coordination level are consist of start-up part and run-time part. The start-up part involves tasks for the configuration and the implementation of controllers, and the run-time part involves tasks for the supervision and coordination of the controllers in closed-loop operation. Also, we show how a supervision level and a coordination level can be designed and what basic elements should be included. Finally, we show the robustness of this scheme by experimental results for task model.

Competitive power is rapidly manufacture product required consumers. Therefore, modern industry have changed from small item many production to many item small production. rapid production is necessary thing at the product development. Thus, rapid prototyping is appeared. If the graphic model was made by CAD, the production can be made in short term. That provide what the part was directly tested by the worker. It provide believable data. This study is experiment on surface roughness of part at FDM

S사는 생산량 증대에 따른 물동량 증가에 대비하기 위하여 물류 시스템 개선안을 수립한 수 , 타다성을 검증하기 위해 시뮬레이션 기법을 채택하여 물류관점에서 현행 시스템 및 개선안에 대한 진단을 실시하였다. 컴퓨터 시뮬레이션 기법은 생산공정에 실질적인 물리적 변화를 가하지 않고도 "What-if" 라는 다양한 시나리오를 작성하고 이들에 대한 분석 및 평가를 통하여 그 가능성을 타진하며 최적안을 도출하는데 유용하게 이용되는 도구이다. 본 진단을 통하여 현행 시스템의 문제점을 정량적으로 파악하였다. 그리고, 물류 개선안에 대한 기대효과를 예측하고 발생가능한 문제점을 사전에 도출하여 시행착오를 최소화하는데 기여하고자 하였다.기여하고자 하였다.
