To execute business collaborations, the business process specification is required and it is generated from the business process model. ebXML, which is the XML-based B2B standard framework for organizations over the Internet, recommends process analyst and modeler to use UN/CEFACT Modeling Methodology for modeling. All the artifacts of the modeling and transformed results between different business models may be registered in the business library for the share and re-use. In this paper, we implement the business process modeler including built-in registry client. It provides not only modeling the business process but also generating the specifications, exporting the metadata about the business model, and registering in the business library.

고가용 E-Business모델을 위해 구축된 나중 웹 클러스터 모델은 구조적 특성상 내부 시스템 노드들이 노출되어 있으며, 불법적인 3자에 의한 고의적인 방해와 공격으로 정상적인 작업수행이 불가능할 가능성을 지고 있다. 따라서 구성된 시스템 노드들을 보호하고 불법적인 사용자로부터의 정보유출과 부당한 서비스 요구를 효과적으로 대응할 수 있는 보안 시스템이 필요하나 제안한 분산 침입 탐지 시스템은 불법적인 침입을 탐지하기 위하여 일차적으로 Detection Agent를 이용한 작업요구 패킷의 검사를 수행하려, 이후 작업이 진행되었을 때 Monitoring Agent를 동하여 작업과정을 관찰하며 허용되지 않는 자원의 접근 및 요구가 발생하였을 때, 다른 시스템 노트와의 긴밀한 협조작업을 동해 침입여부를 판단한다.

정보통신기술과 e-Business의 급속한 발전으로 정보통신서비스를 구성하는 가지사슬과 환경이 빠르게 변화하고 있지만 정보통신서비스 사업자들이 e-Business 도입으로 경쟁력을 향상시키는데는 많은 제약이 존재한다. 특히, 사업자들의 비즈니스 환경이 e-Business 참여를 위한 표준화가 되어 있지 않다는 것이 시급한 문제이다. 이중에서도 메시지교환, 전자카탈로그 등의 단위기술에 대한 표준과 방향은 지속적으로 제시되어 왔지만, 실제 사업자간 발생하는 거래의 형태와 이때 필요한 문서 등에 대한 정의는 미흡한 것이 현실이다. 본 연구에서는 정보통신서비스에서의 사업자간 비즈니스 프로세스 표준모델을 제시함으로써 사업자간 프로세스에 대한 표준화와 활용방안을 제시하고자 한다. 이를 위해 본 논문에서는 정보통신서비스의 공급망을 구성하는 사업 영역을 고객에게 제공되는 서비스 형태를 중심으로 분류하여 정의하고, 각 사업 영역별 프로세스의 유령이 구분되는 사업자 단위를 도출하여 그 관계를 정의한다. 그 결과로서. 각 사업자간에 발생하는 비즈니스 프로세스와 문서를 선정하여 표준화와의 이슈와 대안을 제시한다.

Needs of automation and computerization in the construction industry has been recognized but the implementation of e-business solutions with project management systems has not been fully explored. In order to cope with different management practices in home office and project sites, integration of two popular systems, Enterprise Resource Planning (ERP) and Project Management System (PMS) is essential. The objective of this study is to find ways to functionally and systematically integrate ERP and PMS. With the integration of ERP and PMS, a project will be managed much more efficiently and effectively. It is expected that this study will benefit system integrators and help them to understand construction management processes and integrate the solutions with minimized programming work.

Those of the growth of e-business, the development of the cultural creative industry, the contents and knowledge industry have expanded and diversified the existing business models and created new ones. They are triggering new interpretations and discussions on business models. Such of changing business environment has paved the way for the expansion of design management within the design industry and opened new windows of opportunity for the traditionally small and non-specialized design business. Until now, the design business has not been distinguished from design industry or design service, and has not been viewed as an independent field. Rather, the design business has merely been part of a process. As such, the lack of dear definition and structured system had been a bottleneck for many design companies trying to achieve capital and social success and establish the foundation for growth and for companies striving to advance the design management in developing design business models or growth strategy in line with the changing environment. Against these sort of backdrops, this paper attempts to dearly define the design business. To this end, the paper tries to developed a design business model framework which classifies design business model into four types - customized, ready-made, provider and contract - according to the business activities between the producer and the end user, and business items into product, additional sonics, knowledge and promotion. The framework will expand the definition of design business and contribute to the expansion of design business activities and the development of diverse business models.

This paper provides a corporation's marketing strategy under a ubiquitous computing environment: a WOM(word-of-mouth) marketing using RFID(Radio Frequency Identification) technology and a business model which facilitates the word-of-mouth marketing. To this end, we examine the word-of-mouth communication effects on consumers' life, changes in corporations' attitude toward word-of-mouth marketing, and the difficulties that corporations have in conducting word-of-mouth marketing. The business model this paper suggests makes seamless business-to-consumer and consumer-to-consumer networking possible using the RFID technology and facilitates the word-of-mouth marketing through incentive system of each economic player.

Content services on the Internet is getting attention as a new business model, selling digital content in real-time on the web. However, most of these content-based business is based on advertisement model rather than direct-payment-based business model. One of the difficulty in setting up charge-based content service is that the pricing paradigm of digital content is different from traditional pricing of products or services. The objective of this study is to empirically derive the feasible price response functions for these content services. Based on conjoint analysis of popular attributes of digital content, several price response function models were fitted against the conjoint data, using online movie viewers' preferences for different attributes of the service. Fitted function models were linear, multiplicative, exponential, attraction, and Gutenberg models. attraction model was found to be well-fit with the data for several specific combinations of attributes. Implications for pricing strategy is discussed at the end.

This study aims to determine the factors influencing student performance using the teaching and learning process through e-learning based on the unified theory of acceptance and use technology (UTAUT). This study also sets out to propose additional variables to expand the UTAUT model to be more suitable to use in higher education. This research conducted a literature review, expert interviews, and a self-administered survey involving 200 students at tertiary institutions in Riau province, Indonesia. The questionnaire data were analyzed using SmartPLS 2. This study shows that UTAUT constructs, namely, social influence, facility conditions, and effort expectancy have a significant influence on student behavior and performance, while the performance expectancy variable shows no significant effect. The additional variables, including lecturer characteristics, external motivation, and organizational structure, directly affect student performance. However, concerning student behavior, motivation and environment are the only variables with a significant effect. The results of this study suggest the behavior deteminant such as lecturer characteristics, motivation and environment, and organizational structure improve student performance. This study investigates factors affecting the performance of university students through the learning employing e-learning by developing the UTAUT constructs to include the lecturer characteristics, motivation and environment, and organizational structure in improving student performance.

With the recent surge of public interests in real estate markets, public demand on cadastral information including cadastral maps has been increasing rapidly. However, the torrent system that provides cadastral information falls far short of meeting public demand due to its main focus on government users. In order to reduce the gap between public demand and supply of cadastral information, a new business model is needed that fulfills public needs and at the same time generates profits for service providers. The main objective of this paper is to identify a potential business model that satisfies the above conditions. To achieve this objective, we have explored the unmet needs of public users in real estate transactions and examined whether the unmet needs can best be served by the resources and capabilities of Korea Cadastral Survey Corporation. Then, we have crafted a detail business model i.e., Syndication model, that includes value propositions, resource maps, and revenue and cost estimations. Finally, a plan is proposed to serve government users better with the financial surplus from the proposed business model. The results of this study can be useful for other similar areas including GIS, ITS and telematics, academically as well as practically.
