Nowadays, to change our country into advanced economy, the factor of growth obstacles was to be eliminated, or it is so important that the logistics base establishment enlarges to improve potential productivity. The best strategy to enforce the competition power is that we should be ready for some condition which can do cooperations and association very well. Also it is necessary for actors, government, firm and logistics field, to part their role. The national effort that firm supported by government and community participates in is reduced to achieve rational logistics system because logistics is complicate action flowing to final consumer. That is, self effort is needed for logistics competition system, adjustable arrangement of logistics field, the establishment of comprehensive informations system, logistics rationalization.

Purpose: Despite the popularity of sales promotion as one of the key marketing tactics employed by many companies today, relatively little effort has been devoted to examining an interaction effect between promotion cues and promotion duration. Therefore, this study aims to examine how promotion cues and promotion duration will jointly affect consumers' attitudes toward promotions and purchase intentions. Research design, data, and methodology: The present study conducted an online experiment through the Qualtrics program in which a total of 141 participants were recruited from the Cloud panel members in the U.S. The experiment employed a 2(promotion cue: best-seller vs. limited edition) × 2(promotion duration: long vs. short) full factorial between-subjects design. Result: In the condition of best-selling sales promotion cue, a long promotion duration induced more positive promotion attitude and higher purchase intention, while in the condition of limited-edition sales promotion cue, the use of a short promotion duration contributed more positive promotion attitude and greater purchase intention. Conclusions: Marketers need to take the congruence between promotion cues and promotion duration into full consideration when designing effective sales promotion strategy.

Most of the existing broadband access networks based on DSL, cable modem, and Ethernet support the best-effort internet access service, and adopt the flat rate pricing mechanism. It is almost impossible to provide the differentiated communication services, in current broadband access networks, for the different users and/or the different application services. Currently, however, the advances in multimedia, communication, and security technologies push the interactive and/or streaming multimedia services and VPN services to be widely deployed over Internet, and they require more QoS-sensitive services than the best-effort service. Though various QoS technologies such as RSVP-based IntServ and DiffSern were already developed and under standardization in Internet world, it is impractical to replace the existing QoS-unaware access networks with the QoS-enabled ones at a time to deploy QoS-sensitive services. In this paper, after analyzing current broadband access network architectures and the status of QoS support, we propose a practical approach to support multimedia QoS in the broadband access networks. The approach will be based on the integration of the differentiated pricing and the DiffServ technology. And it will be a step-wise approach to support backward compatibility with the legacy broadband access networks as much as possible.

Quality management has been recognized as an important means to secure business competitiveness for management environment changes and competitiveness reinforcement. An effort of an ISO 9001 certification has thought that it is the best way to practice quality management. This paper checks a quality management situation of manufacturing companies that acquired ISO 9001 certification. Then, this paper investigates whether quality management is actual1y contributing to production performance and proposes proper alternatives for an improvement of production performance.

A procedure employing a Teaching-Learning Based Optimization (TLBO) method is developed to design discrete pin jointed structures. TLBO process consists of two parts: the first part represents learning from teacher and the second part illustrates learning by interaction among the learners. The results are compared with those obtained using other various evolutionary optimization methods considering the best solution, average solution, and computational effort. Consequently, the TLBO algorithm works effectively and demonstrates remarkable performance for the optimization of engineering design applications.

현재 인터넷 사용자의 증가와 더불어 사용자들이 원하는 서비스가 다양해짐에 따라 기존의 Best effort 서비스로는 사용자들이 요구하는 응용 서비스들을 제대로 지원할 수가 없게되었고, 이에 IETF(Internet Engineering Task Force)애서는 사용들의 QoS 제공을 위해 Integrated service model과 Differential service model이 제안되었다. 그러나 소규모 망에서 적용 가능한 Intserv와 대규모 망에서 사용적절한 Diffserv망의 service 방식이 다르기 때문에 End-to-End간에 QoS 제공을 위해서는 이에 대한 망의 연동이 필요하다. 본 논문에서는 두 망간의 연동을 위한 Framework을 제안하였다.

The Subaru telescope is a 8.2m optical-infrared telescope operated by National Astronomical Observatory of Japan since 2000. Its wide field observation capability with good image quality makes the telescope one of the best astronomical facilities. We Subaru Telescope is seeking for international partners for the telescope operation to share science observations, future strategy and development. In the course of this effort, EAO and us exchanged a letter of intent on the planning of collaboration on the Subaru operation in this June. I introduce the contents of the Subaru-EAO LOI and the basic concepts of the Subaru international partnership in addition to a brief report of the current status of the observatory.

In this paper, We propose a new flow control scheme based on Queue Dynamics and it's Estimate Information in order to achieve higher throughput and network efficiency using control of the best-effort traffic. The feedback Information gives a result that compare queue length with queue threshold. Traffic changes at the time when queue length is cross over under the queue thresholds. The performance of the purposed scheme has been analyzed mathematically and we verify efficiency of the proposed method by means of simulation.

기존의 인터넷 기반 데이터 서비스는 'Best-effort' 정책으로 멀티미디어 서비스를 위한 트래픽 제어(traffic control) 기능을 제공하지 못한다. 그러므로 실시간 데이터 전송을 기반으로 제공되는 VOD(Video-on-Demand) 서비스는 사용자가 원하는 QoS(Quality of Service)를 제공할 수 없다. 따라서 인터넷 상에서 트래픽 제어 기능을 갖춘 중개자를 두어 VOD 서비스를 제공하는 방법에 대해 제안한다. 중개자의 주요 기능은 비디오 서버와 클라이언트 사이에 비디오 데이터의 버퍼링 기능을 이용하여 실시간 트래픽 제어를 수행한다. 이런 기능을 가진 중개자를 에이전트라 부르고, 에이전트에 대한 설계 및 구현에 대해 기술한다.

최선형 서비스(best effort service) 방식의 현재 인터넷은 실시간 응용의 출현과 보다 나은 서비스를 기대하는 사용자들에 의해 많은 변화가 요구되고 있다. 최근 사용자에게 서로 다른 수준의 서비스를 제공하는 차별화 서비스(differentiated service) 모델에 관하여 많은 연구가 진행중이다. 두 가지 우선 순위를 바탕으로 서비스를 제공하는 RIO 모델은 차별화 서비스의 대표적인 모델이지만 네트워크 상황에 따라 적절한 서비스 차별화가 이뤄지지 않는다. 본 논문에서는 이를 개선하여 보다 효과적인 서비스 차별화기 이뤄지도록 하였다.
