e-Business가 기업의 경쟁력확보에 필수불가결한 요소로 여겨지면서 많은 기업들이 e-Business 에 대한 투자를 늘리고 있으며, 나름대로 e-Business에 대한 비전을 수립하고 있다. 그러나. 이러한 변화에도 불구하고 e-Business 방향성 제시를 위한 방법론이 개발되어 있지 않아, e-Business 도입을 위한 구체적인 계획의 수립이 어려운 실정이다. 따라서, 본 연구는 e-Business를 도입하고자 하는 기업으로 하여금 e-Business 도입 시 우선적으로 고려해야 하는 e-Business 도입영역을 선정하는 방법을 제시하였다.

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.

최근 IMO의 항해안전전문위원회(NAV) 통신작업반을 중심으로 E-Navigation(E-Nav) 전략개발에 관한 연구가 진행되고 있다. E-Nav 전략개발을 위한 통신망 아키텍처의 설계는 선교시스템의 표준 및 미래 항해 및 해양통신 장비에 관한 국가 R&D 프로젝트 방향을 결정하는 중요한 부분이다. 본 연구는 E-Nav 이용자 요구분석을 통하여 항해안전을 향상시키고 해상운송의 부가적인 이익을 가져다 줄 수 있는 E-Nav 서비스를 도출하고 통신망 기준모델을 설계하는데 목적을 두고 있다. 본 연구에서는 E-Nav 서비스를 크게 안전 및 보안, 해양기상, 조난, 비즈니스, 인포테인먼트(infotainment)의 5가지 분야로 나누고, 각 분야 별로 요구되는 E-Nav 서비스를 도출하였다. 그 결과로서 도출된 E-Nav 서비스 지원을 위한 통신망 아키텍처를 제안하였다.

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.

선박의 안전운항을 중심으로 하는 해양 분야 정책 개발은 주로 사고로부터의 교훈에 따른 규제 강화에 초점을 두어온 것이 사실이다. 최근 국제사회를 중심으로 논의되고 있는 IMO의 e-navigation 전략은 이러한 규제 강화가 아닌 사용자 요구사항에 근거한 새로운 프레임, 새로운 아키텍처의 수립과 그에 기반을 둔 기술 및 서비스의 정의를 통해 사용자 친화적인 정책 수립 및 인프라 구축과 사용자 서비스 제공을 위한 것이다. ICT 기술의 융합과 조선해양산업의 재도약을 위해 필수적인 신 해양정보통신 정책을 개발하기 위해서는 IMO e-navigation 전략 개발 사례와 같이 사용자 요구사항, 이를 충족시키기 위한 서비스의 정의, 그리고 각 서비스를 만족하기 위한 기술의 개발과 같이 아키텍처에 근거한 단계적 개발 방법론이 요구된다. 본 논문에서는 IMO e-navigation 전략 개발 방법론을 분석하여 우리나라의 신 해양정보통신 정책 개발 전략을 위한 분석 결과 및 시사점을 도출하였다.

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.
