  • This paper presents a new approach to evaluate the maximum number of simultaneous switching gates of a given combinational circuit. The new approach is based on an iterative method proposed by Sinogi et al. and applies a simulated annealing strategy to search jot a new solution. The experimental evaluation using ISCAS’85 benchmark circuits shows that the proposed approach has attained an excellent improvement compared with other rotated methods including the iterative method.

  • In this paper, we present a cross-layer analysis of wireless TCP systems over correlated channels. The effects of error correlation on the behavior of link retransmission strategy and the end-to-end throughput of TCP layer are investigated. Based on the cross-layer analysis, an efficient refinement of link layer protocol is proposed by consciously utilizing the information of channel correlations, which leads to the performance improvement of wireless TCP systems.

  • The analysis on the relationships among SPI models and restructuring SPI models according to a common framework makes it possible to compare and integrate the numerous research results about the models. It also makes it possible to assess objectively and accurately the results and benefits of evaluating an organization which has been evaluated according to a partial SPI model according to a new and integrated SPI model.

  • Load Management, is originated from efficiency improvement of energy use, or energy conservaion. Traditionally, electric utilities have constructed new power plants to meet the steadily increasing electricity demand. Power development planning, however, is becoming more difficult in the countries like Korea, Japan, and the United States, and increasing concerns about global environmental problems necessitate changes from existing supply-side options based on fossil-fuel to environmentally agreeable supply strategies. This paper discusses the demand side management strategy with emphasis on the concept, implementation scheme, and current practices employed in utilities.

  • The concept of six sigma was introduced at and popularized by Motorola in its quest to reduce defects of manufactured electronics products. When used as a metric, six sigma technically means having no more than 3.4 defects per million opportunities in any process, product, or service. More important than the technical definition is the concept of six sigma as a disciplined, quantitative approach for improvement of defined metrics in manufacturing, service, or financial processes. This approach derives the overall process of selecting the right projects based on their potential to improve performance metrics and selecting and training the right people to get the business results.

  • 프로세스 개선은 프로젝트의 지속적인 성공과 밀접히 연관된다. 따라서 많은 기업들이 프로세스 개선을 위해 노력하고 있으나 프로세스 개선에 대한 투자 비용, 내부적인 저항, 내부적인 참여 등의 문제로 프로세서 개선의 실질적인 효과를 보지 못하는 경우가 적지 않다. 본 논문에서는 조직내의 충돌을 최소화 하면서 프로세스 적용을 가속화하기 위만 방안으로 점증적인 프로세스 적용 전략을 제안한다. 점증적인 프로세스 적용 전략은 점증적인 개발 프로세스 적용, 점증적인 프로세스 정립을 병행하는 방안이다.

  • IETF proposed Fast Handover mechanism tn reduce the latency during which the mobile node is effectively dusconnected from the Internet. In this paper, we propose three buffering strategies and a bicasting strategy to resolve packet loss and packet disordering problems in Fast Hangover mechanism. Through Java-based simulation we show thats, packet loss and disordering problems have been resolved by our proposal. As the result the buffering and bicasting strategies can reduce the handover delay caused by packet loss and packet disordering, in addition.

  • CRM(Customer Relationship Management) is now moving to the center of corporate strategy because acquiring customers is usually much more expensive than keeping them. Some successful CRM cases of leading companies are surveyed and their critical success factors are discussed in this paper. For successful construction of CRM system, It must be considered some critical factors as follows (i) improvement of customer loyalty, (ii) higher customer profitability, (iii) reduced cost of sales.
