본 연구는 국내기업과 선진 외국기업의 SCM 사례를 중심으로 벤치마킹을 통하여 국내 공급사슬관리(Supply Chain Management: SCM)의 도입에 적합한 성공요인을 발견하고자 한다. 참조 모델로는 SCC(Supply Chain Council)의 SCOR(Supply Chain Operations Reference-model)를 적용하여 SCM의 발전단계모형과 성공요인을 제시하고 이를 통해 국내기업의 SCM의 전략적 도입방안과 SCM의 활성화를 위한 정부의 정책에 지침을 제시하고자 한다

A in-situ experiment was performed to evaluate the pullout resistance capacity of chains which is used as a reinforcement of reinforced earth wall. It was also considered that chain was combined with a bar or L-type steel angle by the transverse reinforcement member in the experiment. As a result of experiment, it is expected that chain can be safely used as reinforcements of reinforced earth wall, although it is concerned that a theoretical estimation of the pullout resistance capability of chain is too conservative.

It is well known that there is a residual subset J of the space of $C^1$-diffeomorphisms on a compact Riemannian manifold M such that the maps f $\mapsto$ chain recurrent set of f and f $\mapsto$ number of chain components of f are continuous on J. In this paper we get the flow version of the above results on diffeomorphisms.

Let M be a manifold with a volume form ${\omega}$ and $f:M{\rightarrow}M$ be a diffeomorphism of class 𝒞$^1$ that preserves ${\omega}$. We prove that if M is almost bounded for the diffeomorphism f, then M is chain recurrent. Moreover, we get that Lagrange stable volume-preserving manifolds are also chain recurrent.

The purpose of this research was to understand the successful establishment of the cultural industry chain in Korea and discover lessons for China to improve its cultural industry. It was concluded that a one-industry development pattern cannot win in market competition and a cultural industry will strengthen its sustainability only through smoothing its relationship with other industries and establishing a cultural industry chain so as to further development and resist crises together.

We persent a method for kinematic calibration of open chain mechanisms based on the product of exponentials (POE) formula. The POE formula represents the forward kinematics of an open chain as a product of matrix exponentials, and is based on a modern geometric interpretation of classical screw theory. Unlike the kinematic parameters in the POE formula vary smoothly with changes in the joint axes;ad hoc methods designed to address the inherent singularities in the D-H parameters are therefore are therefore unnecessary. After introducing the POE formula, we derive a least-squares kinematic calibration algorithm for general open chain mechanisms. Simulation results with a 6-axis open chain are presented.

We introduce here notions of chain recurrent sets, attractors and its basins for general dynamical systems and prove important properties including (i) the chain recurrent set CR(f) of f on a metric space (X, d) is the complement of the union of sets B(A) -A as A varies over the collection of attractors and (ii) genericity of general dynamical systems.

공급망 관리(SCM: Supply Chain Management)는 공급자, 생산자, 고객에 이르는 공급망(Supply Chain) 전체에 대한 합리화된 통합적 관리를 의미한다. 현재까지 최적화와 관련된 분야들에 대한 연구가 많이 진행되어 왔으나 이러한 최적화 값들의 실제 적용에 관한 연구는 미흡하였다. 이에 본 연구에서는 공급망을 모델링하여 원하는 기간 동안의 시뮬레이션을 통해 공급망을 정량화된 데이터로 표현해 주고, 각 구성 요소에서의 운영정책 변화나 공급망 디자인의 변화와 같은 여러 가지 발생 가능한 변인들이 공급망에 어떠한 영향을 미치는지를 나타내 줄 수 있는 Supply Chain Simulator(SCS)에 대한 개략적인 내용을 살펴보고 개발된 SCS들에 대하여 간략하게 알아보고자 한다.

This paper suggests the long-term strategy of the production distribution planning considering the capacity of factory production and the uncertain demand in a supply chain. This paper determines the near optimal capacity of factory production by using the advantages of mathematical and simulation models. Also, the relationship between the capacity from the suggested model and the strategy of production and distribution in a supply chain is studied. Arena is used for modeling and analysis.

In this paper, Glift codes, generalized lifted polynomials, matrices are introduced. The advantage of Glift code is "distance preserving" over the ring R. Then optimal codes can be obtained over the rings by using Glift codes and lifted polynomials. Zero divisors are classified to satisfy "distance preserving" for codes over non-chain rings. Moreover, Glift codes apply on MDS codes and MDS codes are obtained over the ring 𝓡 and the non-chain ring 𝓡_e,s.
