Purchase decision behavior for and satisfaction with apparel among retail buyers and consumers were compared. Kunz's behavioral theory of the apparel fm was the conceptual framework; Oliver's disconfirmation model guided measurement of satisfaction. Buyers and consumers indicated their perceptions about shopping orientations, variables that influenced apparel purchasing decisions, the importance of aspects of customer service and attributes that they expected to find and found when shopping. Surveys were mailed to retailers and consumers identified by random sampling of company lists. Respondents were 66 buyers and 344 consumers. MANOVA revealed differences in retailers 'and consumers' shopping orientations, the influence of variables on purchase decisions, and perceptions of the importance of customer service. Paired sample t tests indicated dissatisfaction for buyers on 10 apparel/shopping attributes and consumers on nine items. Results support the need for vertically integrated manufacturers to redesign strategies that are more appealing to both retail buyers and consumers.

오늘날 웹의 사용자와 컨텐츠가 급격히 증가함에 따라 지능적 정보시스템과 웹 서비스(Web Service) 개념이 여러 분야에서 활발히 연구되고 있으며, 사용자에게 의미 정보를 제공하기 위한 시맨틱 웹서비스의 필요성이 대두되고 있다. 본 논문에서는 시맨틱 웹 서비스를 위한 FXDB (FUZZY XML DATABASE) 시스템 설계 기법과 의미정보(Semantic Information)를 자동으로 실시간 웹 서비스 할 수 있는 방법을 제시한다. 본 논문에서 제시한 FXDB 시스템은 XML 기술과 퍼지기술을 이용하여 웹상의 메타데이타를 데이터베이스에서 의미적으로 자동해석하고 XML 기반 웹 서비스할 수 있는 시스템 구조를 제안한다. 따라서 시맨틱 웹 환경을 위한 메타데이타의 해석을 좀 더 자동화, 지능화 할 수 있는 차세대 웹을 구현하는데 기여할 수 있을 것이라 기대한다. 또한 웹 사용자의 입장에서는 의미정보에 따른 빠른 의사결정과 시맨틱 웹 정보검색이 가능하게 될 것이다.

In this paper, we consider a queueing network model. where the population constraint within each subnetwork is controlled by a semaphore queue. The total number of customers that may be present in the subnetwork can not exceed a given value. Each node has a constant service time and the arrival process to the queueing network is an arbitrary distribution. A major characteristics of this model is that the lower layer flow is halted by the state of higher layer. We present some properties that the inter-change of nodes does not make any difference to customer's waiting time in the queueing network under a certain condition. The queueing network can be transformed into a simplified queueing network. A dramatic simplification of the queueing network is shown. It is interesting to see how the simplification developed for sliding window flow control, can be applied to multi-layered queueing network.

Today, s Businesses can only survive if they can sdapt fast, and this means their IT systems have to adapt too. A challenge for identifying and codifying reengineering expertise is to capture Both aspects of a successful enterprise business architecture(EBA) and suitable description language, with the contexts in which it works. In connected with the state of the art in the field of Web Services architecture and EBA, we propose to exploit the concept of business process execution language(BPEL), one among of description language. In addition, we review current a issue and problem of EAI and Workflow, and outline the main ingredients of a BPEL and EBA for building flexible Web Service. This paper is exploratory study in associated with enterprise architecture(EA) and description language.

With the proliferation of smart devices, applications under ubiquitous environment must provide transparent access to computer resources. However, existing u-Logistics systems can not properly react on such requirements, because the status information of objects is input only in fixed milestones by system's operators. In this paper, we introduce an event notification service suitable for u-Logistics environment. The system is based on RFID infrastructure and provides real-time tracking by combining the event of objects with location information received from GPS satellites. The system also provides a graphical user interface based on a state/transition approach, making it easy that clients facilitate definition of profile, and uses XML structure to more easily represent and exchange events.

In this paper, a predictive fuzzy control algorithm to supervise the elevator system with plural elevator cars is proposed and its performance is evaluated. Elevator group controller must decide the service elevator for a registered hall call to satisfy the multiple control objects. The proposed group control algorithm ensures the efficient operations of the group cars and provides the improved level of service, coping with multiple control objects and uncertainty of system state. The feasibility of the proposed control algorithm is evaluated by simulation on computer.

Recently, the public postal service of Korea confronts with business environment changes such as the opening of postal market and appearance of the domestic competitive enterprises. It is the current state that the public postal service of Korea should have a competitive edge by the productivity improvement of business processes. In this paper, we proposed new working tables for manual letter sorting which is one of the important process in mail center. We suggested standard working method and standard time in a mail center Based on these, we established the procedure for setting up a fair day's work in other mail centers. By the result of this research, we expect that the productivity of the mail sorting operation will be increased.

TD-SCDMA is considered as an innovative Chinese 3G technology adopted by the ITU for the IMT-2000 family. TD-SCDMA combines TDMA and CDMA components to provide more efficient use of radio resources. According to the traffic volume and activity level, the operation mode of a mobile terminal can change from one state to other states. This paper focuses on the problem of recovery delay from inactive states, and proposes a resource management algorithm, which holds some resources for rapid recovery of service after the service determines to release the dedicated resources.

As people's interest about food service rises, curiosity about correct foodservice company's information is rising on own inclination and necessity than usual foodservice company. Full text search site that do to foodservice company hereupon is operated, it is becoming menu that do not fall in name of ' Eumsikjeomchatgi ' in a representative search site such as Yahoo, Empas, Hanmir and so on. But, is not beam margin battle array that these search engines find data that they want being applied perfectly in site FACE that is use up to now. Also, is looked that there is problem about practical use service and search. Because search effect of site by that investigate consumers' awareness and practical use turkey for foodservice company search site and diagnose present level, it is thing to grope improvement. This research may supply one suggestion point establishing by more effective marketing communication strategy through internet hereafter.

Several ISDN (Integrated Services Digital Network) protocols have implemented at ETRI (Electronics and Telecommunications Research Institute) in an experimental network so that functional characteristics of the protocols under test could be certified against their protocol specifications with the help of the ETRI protocol test facilities. This paper describes ETRI protocol test architecture and its application to testing the NSP (Network Service Part) protocols : MTP (Message Transfer Part) level 3 and SCCP (Signalling Connection Control Part) of the CCITT CCS (Common Channel Signalling ) system No. 7 The test architecture presented here allows tests for two different protocol classes : peer-to-peer and multipeer protocolos. Some extensions are made to the conventional test architectures, namely the test coordination, test result transfer and network state observation method.
