인터넷의 급속한 확산은 기존 시장의 개념을 확대, 변화시키고 이러한 변화된 시장에서 기업은 새로운 비즈니스 패러다임의 변화에 적응하지 못하면 경쟁력을 확보할 수 없는 상황에 처하게 되었다. 기업의 비즈니스 패러다임 변화의 중심은 인터넷 기반의 e-Business라 할 수 있다. e-Business의 핵심은 인터넷과 정보기술을 이용하여 기업의 내부 프로세스와 기업간 그리고 고객간 외부 프로세스의 투명성을 제고하여 비용을 최소화하는 데 일차적인 목적이 있다. 그러나 e-Business 전개에 있어 기업 내/외부의 프로세스 효율화를 위한 수요측면의 적용 주체 이외에도 이러한 전개를 도와주고 각종 하부구조, 서비스 및 장비를 제공하는 공급 주체도 존재한다. 수요측면에서의 전자상거래를 포함하여 많은 e-Business 관련 연구가 있었으나 공급측면에서의 e-Business 연구는 다소 부족한 실정이다. 이에 본 고는 다소 실험적 성격을 가지고 공급측면에서 특히 통신서비스 사업자 측면에서의 e-Business 개념, 모델, 유형 등을 기존 연구의 연장선상에서 확대, 고찰한다.

An electronic services which are based on Internet/Intranet business transactions are available to e-market places and get the broader business concepts. Component-based e-commerce technology is a recent trend towards resolving the e-commerce chanange at both system and ap-plication levels. The basic capabilities of component based systems should include the plug and play features at various granularities, interoper-ability across networks and mobility in various networking environments. E-business application developers are attempting to more towards web-service as a mechanism for developing component-based web-applications. Traditional process and development models are inadequately architectured to meet the rapidly evolving needs for the future of scalable web services. In this thesis, we focus specifically on the issues of e-business system architecture based on web service for establishing e-business system. We specifies and identifies design pattern for applying e-business domain in the context of multiple entities. We investigate prototype and frameworks to develope components for e-business application based suggested process. We present a worked example to demonstrate the behavior of Customer Authentication System(CAS) development with component and recommend process. Final]Y, we indicate and view on future directions in component-based development in the context of electronic business.

As ubiquitous computing technology is proliferating, a wider range of u-services applying ubiquitous computing technology has been implemented and some of the u-services have been actively considered for commercialization. Accordingly, establishing corresponding business models based on u-services also have been increased. However, structured methodologies to build u-service business models are still in its very early age. Moreover, since most of the legacy business model formulation and analysis methodologies have stressed on conventional or digital services, not u-services. Hence, the purpose of this paper is to propose a structured methodology of formulating and analyzing business models for u-services. An illustrative example is described to show the feasibility of the proposed methodology. To do so, Business Model Diagram (BMD), which adopts model components for u-services, is newly developed.

The purpose of this study was to identify the impact of e-commerce system satisfaction on e business success factors. We developed the questionnaire for measuring system satisfaction and success factors and tested internal reliability and construct validity. Cronbach's alphas of all system satisfaction factors were above .79 and that of e business success factors were above .82 except partnership (.66). In the regression models, we tried to identify all possible independent variables such as individual factors, organizational factors, system vendor size, order items in their systems and system satisfactions. Using Partial F-test, the regression model with system satisfaction factors, individual and organizational factors was identified as the optimal model in explaining the dependant variable. In the best model, system readiness and timeliness was significant determinants of e-business success evaluation. After using 7 success evaluations factors as the dependant variables, only three models were significant linear models, which were the models with partnership, CEO willingness to e-commerce and e-commerce support. In those models, system readiness and timeliness showed consistent influences to success factors.

Mobile 유통은 전국에 약 3,000여개의 대리점과 7,000여개의 판매점등 10,000여개의 업체가 Mobile의 물류, 판매에 관여하고 있으며, 이동통신사업자의 매월 정책변경에 의해 가격구조의 변동이 발생하며, 타 제품군에 비해 상대적으로 변동폭이 넓어 물류 System의 정착이 이루어지지 못하고 있다. CRM측면에서도 이동통신사업자의 CRM Center에 의지하고 있으나, 고객 관리의 책임이 이동통신 대리점에 귀책되고 있어, 물류주체인 대리점과 판매점주가 사용할 수 있는 편의성이 뛰어나며 확장성이 있는 Logistics & CRM Management System의 필요성이 그간 꾸준히 제기되어 왔다. 본 논문에서는 물류와 고객 CRM의 1차 주체인 대리점과 판매점의 Logistics & CRM 통합관리 System을 e-MLBM과 e-CRM을 이용하여 설계하며, e-MLBM & e-CRM의 경제성분석을 통하여 향후 국내 이동통신 대리점들의 발전방향에 대해 논한다.

Lack of trust is major reason for many company to take a cautions stance towards business-to-business electronic commerce. Especially innovative business models such as online business-to-business marketplaces face the lack of not only having to give their members and partners faith own capabilities and reliability, but also to ensure that the respective parties interacting through them have trust in each other. This paper is empirical study on the trust factors affecting the repurchase intentions in a B2B e-Marketplace by survey instrument based on Likert-style 5 point measurement scale. The objective of this paper is evaluation of relationship between repurchase intentions and trust. The focus of this paper is the antecedents and consequences of buyer trust in a B2B e-Marketplace, not trust intermediaries or in third parties that might mediate between the buyer and e-Marketplace. The findings of this study are expected to increase the awareness of B2B e-Commerce adopter and implementers about the importance of trust in e-commerce participation.

The purpose of this study is to develop a on-line design tool for effectively coping with e-Business environment, or product design process into a Cyber model for traditional manufacturers which attempts new product development under such environment. It was finally developed as a model named $\ulcorner$Design Vortal Site; e-BVDS) that was based on the structure and style of internet web site. Results of the study can be described as follows ; \circled1 e-Business is based on the Internet. All processes in the context of e-Business require models whose structure and method of use are on-line styles. \circled2 In case that a traditional manufacturing business is converted into e-Business, it is better to first consider Hybrid Model that combines resources and advantages of both such traditional and digital businesses. \circled3 The product design process appropriate for e-Business environment has to have a structure and style that ensure utilization of the process as an Internet web site, active participation by product developers and interactive communication between participants in designing and designers. \circled4 $\ulcorner$e-BDVS) makes possible the use of designers around the wend like in-house designers, overcoming lack in creativity, ideas and human resources traditional business organizations face. However, the operation of $\ulcorner$e-BDVS$\lrcorner$ requires time and budget investments in securing related elements and conditions. \circled5 Cyber designers under $\ulcorner$e-BDVS$\lrcorner$ can easily perform all design projects in cyber space. But they have some limits in playing a role as designers and they have difficulty in getting rewards if such projects completed by them are not finally accepted. \circled6 $\ulcorner$e-BDVS) ensures the rapid use of a wide range of design information and data, reception of a variety of solutions and ideas and effective design development, all of which are not possible through traditional processes. However, this process may not be suitable to be used routine process or tool. \circled7 $\ulcorner$e-BDVS$\lrcorner$ makes it possible for out-sourcing or partners businesses to overcome restrictions in time and space and improve productivity and effectiveness. But such they may have to continue off-line works that can not be treated on-line.

This paper presents Web service based ASP (WS-ASP) model for QR(Quick Response) system, supply chain management system in the textiles and clothing industry. The Korean textiles and clothing industry is mostly composed of medium and small-sized companies, which are not capable of recruiting If specialists and making a large scale investment in IT. ASP model not only let them obtain QR system at relatively low usage cost, but also take higher vendor risk due to high dependency. This paper argue that WS-ASP model is appropriate for QR systems by complimenting ASP model with lower vender risk, which results from re-integrating software-on-demand services distributed to several QR specialized WS-ASP vendors.

This study aims to forecast the exchange rate of the Chinese Yuan against the US Dollar by a combination of different models as proposed by Poon and Granger (2003) during the Covid-19 pandemic. For this purpose, we include three uni-variate time series models, i.e., ARIMA, Naïve, Exponential smoothing, and one multivariate model, i.e., NARDL. This is the first of its kind endeavor to combine univariate models along with NARDL to the best of our knowledge. Utilizing monthly data from January 2011 to December 2020, we predict the Chinese Yuan against the US dollar by two combination criteria i.e. var-cor and equal weightage. After finding out the individual accuracy, the models are then assessed through equal weightage and var-cor methods. Our results suggest that Naïve outperforms all individual & combination of time series models. Similarly, the combination of NARDL and Naïve model again outperformed all of the individual as well as combined models except the Naïve model, with the lowest MAPE value of 0764. The results suggesting that the Chinese Yuan exchange rate against the US Dollar is dependent upon the recent observations of the time series. Further evidence shows that the combination of models plays a vital role in forecasting which commensurate with the literature.
