As competition in manufacturing enterprise is contested, the scope of safely production planning, manufacturing enterprise should ensure, has been reduced. The more upstream of SCM, the more reduction of scope of production planning. As a result, order fluctuation is more sharply contested. Through improving the logistics network, it is best way that the end user's demand information is conveyed to upstream of SCM, but it is difficult in fact. In this paper, it mention the way of robustic adjustment, in the suppliers' point of view, the end user's demand information is dammed up, as they postpone responding the customer's order as a possible. And it will show the result of appling the way, as a case study.

In this paper, we introduce a quality of experience (QoE)-provisioning mobility management scheme. The emphasis is on a mobility-aware QoE solution enabling network components to recognize the mobility pattern of an end-user and to prepare a handover in advance. We further focus on an energy-adaptive QoE solution based on the energy profile providing the preferred pattern of energy consumption and an energy preference check engine determining whether the provision of the service that the end-user requested is suitable to QoE or not. Lastly, we concentrate on a network-based intelligent mobility management scheme adopting the calm service and the balance. Consequently, we conclude that the proposed schemes improve the handover latency, QoE metrics, and energy efficiency simultaneously.

This paper discusses two algorithms for recommending notebook computer (NBC) and workstation adjustments so that the user can assume an ergonomic seated posture during NBC operation. Required input data are the user's anthropometric data and physical dimensions of the NBC and the workstation. The first algorithm is based on an assumption that there are no workstation constraints while the second algorithm considers the actual seat height and work surface height. The results from the algorithms include recommendations for adjusting the NBC (tilt angle of the NBC base unit, angle between the base and screen units, and base support height) and the workstation (heights of seat support and footrest, and distance between the body and the NBC).

This paper tries to a n.0, pply the concept and process of marketing which have been developed in profit sector to library management. Since the end of 60's certain marketing researchers, among them Kotler, Levy, and Shapiro have advanced the theseses that marketing is not just a business organization as well. Recently libraries have been interested in markeing also. Marketing is a concept of sensitively serving and satisfying human needs through voluntary exchanges of value. Library is a value exchange system in which library service is exchanged with community's patronage. In order for library user to involve in the value exchange system voluntarily, library should analyze user's needs and offer products satisfying the needs. For doing this, library should understand marketing. In this paper, author introduces the marketing concepts and process, tries to show how to a n.0, pply the key concepts and process to public library management. The needs of marketing in library sector, the effectiveness and barriers in a n.0, pplying marketing to library also discussed.

A certificate is important media for the purpose of offering user-authentication service on PKI system. In the paper we analyzed management implement which could make the efficient use of a certificate. This implement called ClientCA will make efficient use of the service about user-authentication consisting of the basis in the age of information through efficient management and partial use of each certificates. Especially, ClientCA could be used efficiently by grafting a small group of PKI system which is operated with particular purposes.

Recommendation Systems are information technologies that E-commerce merchants have adopted so that online shoppers can receive suggestions on items that might be interesting or complementing to their purchased items. These systems stipulate valuable assistance to the user's purchasing decisions, and provide quality of push service. Traditionally, Recommendation Systems have been designed using a centralized system, but information service is growing vast with a rapid and strong scalability. The next generation of information technology such as Cloud Computing and Big Data Environment has handled massive data and is able to support enormous processing power. Nevertheless, analytic technologies are lacking the different capabilities when processing big data. Accordingly, we are trying to design a conceptual service model with a proposed new algorithm and user adaptation on dynamic recommendation service for big data environment.

Defect dispute has been a continuous claim that concerning a apartment building. However, objective standard of judgment is inadequate to solve defect dispute. Furthermore, it need to scientific evidence that composited standard of judgment. This evidence has a necessary to collect a data for a long time and systematically analyze. Therefore, it need to develop smart information management system, in this study, it review user-oriented condition as swot analysis.

Most of searching systems used by shopping-mall provide too much information for user requirements or fail to provide appropriate items reflecting customer's preference. This paper aims to design and implement the product searching systems based on customer preference which will enable efficient product selection in the internet shopping-mall. The proposed system consists of user/provider interface, searching and model agent, data management system, and model management system. Especially, we construct the searching pattern database to support fast search using association mining method. And this system includes the customer-oriented decision model which shows the highly preferred products. Input weight value per attribute and preference level should be needed to compute priority grade of preference.

Risk management or risk-based approach of software project management was developed to explain the effects of requirement uncertainty, control standardization, interactions on software quality. Based on a prior theory, five hypotheses were derived and empirically tested using a survey design. Data from 117 members in 3 SI companies support for the path model, and three of five hypotheses. The results showed that decreases in requirement uncertainty and increases in control standardization were directly associated with increases in the interactions between user and project teams, which, in turn, led to increases software quality. The findings suggested that the direct effect on software quality is primarily due to the interactions between user and project teams, rather than requirement uncertainty and control standardization.

In this paper, broadcasting contents management system which is for sharing user-created information in restricted areas is proposed. By the proposed system, the information is compulsively sent to a television set receiving broadcasting contents via various transmit media. So, user should be contacting the information while they are watching broadcasting contents.
