Real-time supply chain environments based on RFID will be an important topic in future society; Nevertheless, adopting RFID in real industry SCM is still in its infancy. The aim of this paper is to develop the physical framework of a fully adopting RFID system from manufacturing to recycle phase and measure the effect. So, we built a simulation station with fully appling RFID and analyzed benefits with mathematic model. Then, specifying the advantages and improvement scheme for real industry limitations were suggested. This work concluded that fully appling RFID in SCM gives improvement of quality and service to both production and consumer.

Plasma nitrocarburizing treatment was performed for SCM 435 steel by using a plasma ion nitriding system. The effects of the variation of nitrogen and methan contents upon the hardened layer was investigated. Both the thickness of the compound layer and the amount of $\varepsilon$ phase in the compound layer increased with increasing nitrogen content. However, the thickness of the compound layer decreased due to unstable plasma for an atmosphere containing 90% $N_2$ gas content in the gas mixture. The amount of $\varepsilon$phase in the compound layer increased with increasing $CH_4$ gas content. For $CH_4$ gas content more than 2% in the gas mixture, the thickness of the compound layer decreased due to the formation of $\theta$ phase.

In recent years, most of Supply Chain Management literature has emphasized the importance of information sharing among supply chain partners, but empirical researches are few until now, especially in Korea. The purpose of this study is to develop an empirical model focusing on information exchange among partners in supply chain, and to analyze the main factors influencing the causal relationship between information exchange and performance. Based on cross-sectional questionnaire survey on Korean manufacturing firms, this study analyzed the factors influencing information exchange such as environmental factors, organizational factors, relationship factors, and information characteristics of the sample firms. Our major findings might provide many useful insights for managers in exploring the most efficient system for information exchange among partners in the context of SCM.

The company was focusing on production which was partial mission rather than acquiring the information of customer in intensive process industry. The company accepted loss which is from over-production, losing of opportunity. After changing to web environment, supply chain is more complicated and need of customer is more various. As a result the company hard works on controlling production rates, production quantities in production area and gathering exact information which is about available resource and available quantities. Cooperated demand planning have to get decreasing of inventory, improving of customer service in supply chain management. Specially demand planning that considers allocation of capacity is executed in Iron-Industry. Demand planning must be classified by customer, region and supply position level.

오늘날 기업환경은 고객의 요구에 대응하여 적시에 효율적으로 상품과 서비스를 공급하고 전체비용의 대부분을 차지하는 물류와 재고비용을 줄여 기업의 이윤을 극대화하는 것으로 변화하고 있다. 예전에 기업위주의 시장형성에서 고객위주로 시장이 변화하고 있는 것이다. 이에 따라 기업은 고객의 요구에 능동적으로 대응하기 위하여 리드타임의 단축이 필수적인 요소가 되어가고 있다. 이러한 기업환경에 변화에 따른 대안으로 나온 것이 실시간 제조와 공급사슬망관리(Supply Chain Management : SCM)이다. 본 연구는 실시간 제조를 지원하기 위하여 제조업체와 협력사간의 물류에 있어 Goldratt의 Drunm-Buffer-Rope 스케줄링을 이용하여 물류창고라는 Buffer를 두어 협력사중 재고의 부족현상이 일어날 경우에는 공급체인상의 능력제약자원(Capacity Constraint Resource: CCR)을 찾아 능력제약자원이 되는 협력사에 대하여 생산을 독촉하고 물류창고에서는 부족재고에 대한 불출을 개시하여 재고의 완충을 도모하고자 한다. 제조업체와 협력사간의 정보를 실시간 감시시스템(Real-Time Monitoring System : RTMS)를 응용하여 웹상에서 공유하며, 실시간 거래가 가능토록하는 공급사슬망 구축에 관한 연구와 이를 프로그램 구현을 통해 실제적으로 시험해 보고자 한다.

In the supply chain, The ATP function doesn't only give customers to confirmation of delivery. It can be used by the core function with ATP rule that can reconcile supplies and demands on the supply chain. Therefore We can acquire the conformation about accuracy on the due date of supplier by using the ATP function of management about real and concurrent access on the supply chain, also can decide the affect about product availability due to forecasting or customer's orders through the ATP. This study analyze the data concerned with ATP and define the necessity on a SCM solution. Under the these environments, after defining the ATP rule that can improve the customer value and data flow related the CRM, we propose the advanced ATP model that proposes the method and classification system that can flexibly aggregate the ATP data with ATP rule on the supply chain.

Now, many studies of industrial field are focusing on the whole optimization of SCM. But, the reason for making simultaneity of the whole system of SCM difficult is reduced scale of studies on ordering area in SCM reducing the complexity. It's an important issue how to allocate orders in the environment of many suppliers under special situation. Through this thesis, this research intends to expect systematic and arranged supply of distribution area which can make a decision while allocating product orders and quantity and maintaining service standard suggested by minimizing total purchase costs.

바이트 단위로 접근이 가능하고, 비휘발성을 가지는 SCM(Storage Class Memory)을 이용하여 프로세스의 작업공간으로 활용함과 동시에 파일을 저장하는 형태의 운영체제 기법에 대한 연구가 활발하게 이루어지고 있다. 본 논문에서는 이러한 형태에서 파일이 저장되는 방법을 토대로 프로세스 생성 시 실행 파일의 읽기 전용의 특성을 가지는 실행 코드를 프로세스 공간에 직접 매핑하는 기법에 대하여 제안한다.

개방형 카드 플랫폼의 개발로 전통적인 카드 플랫폼 모델의 문제점을 해결할 수 있었으나 기존 카드 관리시스템으로 개방형 카드 플랫폼을 관리 할 수 없었고 그 대안 시스템으로 SCMS가 개발되었다. SCMS가 개방형 카드 플랫폼에 있어 통합 관리를 수행하지만 주요 기능인 카드 후발급에 대한 효과적인 인터페이스를 가지고 있지 못하다. 본 논문에서는 스마트카드 관리시스템을 이용하여 효과적인 카드 후발급을 위한 카드 후발급 인터페이스를 설계하였다.

Single chain-monellin (SCM) was recently constructed by fusing the two chains of monellin. From the view of protein folding, SCM serves as an ideal model system especially in tackling ${\alpha}$-helix-${\beta}$-sheet interactions due to the following reasons： First, it consists of simple distinct structural elements (${\alpha}$-helix and ${\beta}$-sheet) which are assembled in a perpendicular manner.(omitted)
