e-Business is considered as a essential factor for sustaining competitive advantage and then enterprises increase investment in e-Business infrastructure and establish e-Business strategy. But there is not a methodology supporting e-Business strategy and then enterprises that are planning to introduction of e-Business have difficulty in creating vision and executable plan. Therefore this paper has a objective to offer a method for selecting e-Business domains among business activities. To do this, evaluation framework and evaluation criteria are developed for each business activities and model that supports deciding investment priority is constructed.

This paper examines to focus on General Strategy of e-logistics activity for SCM(Supply Chain Management) Build-up, especially the field service logistics integration. And this research analyzes the case study(Business of Strategy Group Unit) Survey involving effective logistics management that leads customer satisfaction, seeking to find out the key elements of competitive policy. Because problems arise from the differences between their goals and structures, which cause each side to feel vulnerable to opportunism or shirking of responsibilities by the other. The goal of a logistics system is to ensure that every family planning client always receives the contraceptives partner wants, and that they are in good condition and have not expired. In order to select, procure, and distribute the right quantities of the right contraceptives, managers of the logistics system must keep informed of the rates of use of each contraceptive and of the quantity of available supplies. As a result, We propose that a firm's e-logistics safe strategy is an important locus innovation and a crucial source of value creation for the firm its suppliers, partners, and customers.

This paper describes the Optimal PWM strategy to reduce a pulsating harmonic torque for a variable-speed drive of 3 phase induction motor. This paper suggests the new Optimal control theory which consists of 1) defining a performance index related to the unwanted effects of the voltage harmonics, (i.e., the components of pulsating harmonic torques) 2) achieving its minimization by a suitable choice of the switching patterns. (i.e., of the commutation angles) This PWM strategy is compared with the conventional SPWM strategy by numerical method. It is believed that this proposed strategy can reduce more harmonic components and pulsating harmonic torques than SPWM strategy. Also, We could verify the validety of the numerical method by a result of simulation analysis of a variable speed 3phase induction motor.

Recently, electronic-book (e-book) market is growing rapidly due to the evolution of information technology and e-book standard EPUB. Users can search e-book on-line and download easily to their e-book readers such as amazon's kindle or smartphones. On the other hand, there is lack of e-book contents for the reading disabled people because of high cost of making e-book accessibility for the reading disabled people. If we can translate EPUB specified e-book contents to the alternative e-book contents suitable for the reading disabled people, then there are many advantages to acquire various types and large volumes of e-book contents for the reading disabled people. This paper suggests a new electronic publishing ecosystem for the reading disabled people using e-book translation method. It also suggests a promotion strategy of e-book market for the reading disabled people.

Based on the levels of inter-organizational information flow and the degrees of suppliers' power, this study aims to develop a framework useful for classifying four types of the buyer's e-commerce strategies in manufacturing firms: e-marketplace, e-partnership, e-procurement and supplier's e-marketplace (e-distribution). We adopted a multi-methodological approach by mixing both qualitative and quantitative methods. After developing a framework, through the cases of Cisco, JAL, Toyota Motor, KIST, AMP, and 3M, this paper aims to confirm the actual existence of the four forms of e-commerce. The results from the cases supported the four types of e-commerce strategies in manufacturing firms. With the empirical data, we also demonstrated the configuration of the framework and the four types of e-commerce strategies, and identified the characteristics (i.e., size, age, actual adoption rate of the each type of e-commerce, and supply-chain performance) of the organizations employing each strategy.

The research on an E-Navigation(E-Nav) strategy development has recently carried out by the IMO sub-committee on safety of navigation(NAV). The design of communication system architecture is a key factor in the E-Nav strategy development and it may drive the direction of a national R&D project on future navigational and marine communication systems. This study aims at designing a standard model of E-Nav communication network architecture, which enhances navigational safety and provides additional benefits in marine transportation. To achieve this purpose, authors have suggested E-Nav services, which are divided into five categories, i.e., safety and security, maritime meteorology, distress, business, and infotainment, by analyzing the related user requirements. As results, this paper proposes the E-Nav communication network architecture that consists of the navigation and communication equipments.

Many studies have suggested that e-commerce value creation potential depends on four interdependent factors Lock-In, Complementarity, Efficiency, and Novelty. In order to survive in the recent fierce competition, companies have also secured e-Trust that strengthens long-term business relationships by reducing consumer uncertainty. This study, while analyzing the value creation factors (Lock-in, Complementarity, Efficiency, Novelty, e-Trust) of recent e-commerce (online shopping mall) companies from the point of view of purchase intention, customer value (Functional value, Emotional value, Social value) We present an academic proposition that can also examine the mediating effect of value). First, through previous studies on value-based strategy and value creation in e-commerce, various discussions on the theoretical background necessary for effective value-based strategy establishment and strategy execution of e-commerce (online shopping mall) companies were reviewed. Second, it provides academic discussion and practical implications by presenting academic propositions on the value creation factors of e-commerce (online shopping mall) companies, purchase intentions, and customer value, and confirming the basis through empirical analysis.

During the past several decades, the development of the maritime policy have been focused on the level of regulation based on the lessons from the individual accidents. Recently, the development of IMO e-navigation strategy has been discussed actively and has been focusing on the new frame and architecture based on the user requirements and definition of function and services for user requirements, which might produce the user-friendly policy, infrastructure and user service. For the new maritime ICT policy getting fusion of ICT and innovation of ship/ocean industry, the overarching methodology, as IMO e-navigation strategy, should be applied to primarily setup the architecture from the user requirements to technology. In this paper, we analyze the IMO e-navigation strategy procedure and provide the consideration and lessons for the strategic methodology to develop a new maritime ICT policy.

The purpose of this study is to classify customer by e-mailing responsiveness on time-series analysis and testify the effectiveness of grouping by ROI analysis. Response recency, response frequency and Activity(RFA) of e-mailing systems were adapted for Customer segmentations. ROI analysis were consisted of open, click-through, duration time, personalization, conversion rate and email loyalty index of email systems. Major findings are as follows: RFA analysis is used for customer segmentations that is fundamental process of e-CRM applications. Customer segmentations were loyal customer, odds customer, dormant customer, secession customer and observation customer by RFA grouping. Loyal customer group has high point in all ROI index compared to other groups. These results indicated that customer responsiveness of e-mailing systems were appropriate methods to grouping the customer with demographic variables. Therefore, effective e-mailing marketing strategy of e-Biz have suitable active DB and Behavior targeting is best approach to enforcing the target e-mailing marketing.
