As the ubiquitous computing technology (uT) is prevailing, applying uT is more likely to transform the legacy way of doing business to a new way with the goals of ubiquitous computing: strategic use of information resources by using them everywhere, every time, with any devices for any services. These opportunities naturally require the provision to assess the degree of the transformation from the legacy IT-based e-business to the uT-based business. However, research about assessing the degree of u-transformation has been still very few. Moreover, even deciding what is ubiquitous or not is obscure. Hence, this paper aims to propose the methodology for assessing the degree of u-transformation oriented by the teleology of ubiquitous service, which intends to fully make use of uT in creating new business of next generation. Through the literature review, we developed the methodology to check whether the provided service is ubiquitous or not based on the capabilities that technologies have. and then, the methodology developed to assess the technical requirements that the uT should have when the transformation is considered through the focus group interview based on the literature review of the capability. A two-layered approach is introduced to assess not only the level of ubiquity but also the degree of u-transformation.

U-Publication, the Tag-Embedded publication, is one of U-Media. U-Media is defined as a media where human creates and consumes content through not only human cognitive and perceptual processes but also through the interactions between surrounding digital systems. U-Media provides information by generating, collecting, and attaching the content itself and the related information based on the interaction of the bio-systems incorporating digital information and devices embedded in humans, and surrounding objects including external digital devices. Using U-Publication, readers consume its content not only in offline but also online through a mobile RFID reader which touches and connects the URLs embedded in the RFID tags attached to it. Readers can consume the additional content though the hyperlinks attached to U-Publication and perform commercial activity as well as consumer the printed content. This paper defines the RFID-Tagged publication, proposes its related business models, and evaluates the alternative business models through a simulation study.

One of the innovative and most promising approaches to new high-tech business formation from university is technology business incubators, which attempts to enhance small high-tech start-up firms' chances of survival. To date, there is few comprehensive effort to do a comparative study of technology business incubatiors between European Countries and U.S. to evaluate the impacts of them on regional development. With these consideration in mind this research anlayzed key findings of 6 case studies of university related Technology Business Incubators in the U.K., Germany, and U.S. to explore relationship of university to regional development. These included Cambridge Science Park(CSP) '||'&'||' West of Scotland Science Park in the U.K., Dortmund Technologiezentrum '||'&'||' Berlin Technologiezentrum, and Rensselaer Technology Development Center of the Georgia Institute of Technology in the U.S. The primary objective of this study was to advance our understanding of the impact and utility of technology business incubators and to get some policy implications for the future development in this area in Korea. Among the major question examined hear was "how do they contribute the overall economy of the communities in which they are located\ulcorner". The results of the case study about this question were very positive. The technology business incubators contributed to foster new high-tech small business formation from university, to facilitate the cooperation between university and industry and Incubator tenants created jobs and income, pay taxes, and in doing so, had a multiplier effects on the local economy. The same was true of incubator graduates. With this consideration in mind the university related business regioned development policy in korean local communities.

RFID(Radio Frequency IDentification) systems is a wireless frequency recognition technology that can be used to recognize, trace and identify people, things and animals using RFID. Recently, RFID systems have emerged as new forms of interorganizational systems(IOS). Because of their capability for real-time identification and tacking over large distances, some believe that RFID systems will fundamentally change the my companies do business. The purpose of this study is empirically examined RFID systems adoption for u-business. To achieve this purposes, we were collected 72 questionnaires from Korean companies. In this study, RFID systems adoption was influenced by top management support, information systems maturity, competitive pressure, trust perceived advantage of u-business, compatibility of RFID tag. However, firm size, cost exercised power, did not affect significantly on RFID systems adoption. In the conclusion, study's limitations md implications treated.

The first full-scale u-City operation has started in Dongtan u-City. As local cities take over and operate the u-City, unexpected issues arise such as securing the budget of operating costs and self-providing the costs with business models utilizing the u-City assets. The paper presents a strategy for solving these issues. The strategy provides a foundation(infrastructure) for long-term operation models which may reduce the long-term operating costs. In order to establish the economic operating framework of u-City, suggested are some cost-reduction models based on the operating costs structure. For each model, a base framework with comparative analysis of operating costs is provided. With these models, each u-City may select a relevant model according to the characteristics of it. We hope that the framework provides the foundation for efficient and sustainable u-City operations.

Understanding characteristics of Internet businesses from cross-cultural perspective could offer valuable insights on developing business strategy and policy. This work is concerned with revealing divergence and convergence of Internet business models in their financial performance, given organizational conditions and cultural context. For this, we studied the association between organizational attributes (core activity, origination, firm age, and industry) and their effects on a firm's financial performance (gross revenue and net income). Relevant data was gathered from representative Internet firms in Korea and U.S. Data analysis indicated that there exist both similarities and differences between Korea and U.S and year 2003 and 2006. While core activities and industry types of U.S. firms has not been changed much between the periods, Korean firms show much difference. In addition, while core activities and industry type were found to have strong relationship with financial performance, age and origination of a firm weak connections with financial performance. This study is expected to provide a foundation for developing more robust and systematic research model and performing further empirical research in this area.

Previous U-Commerce researches have dealt with the business support systems for traditional commerce space such as real world shopping malls. This paper investigates U-Commerce business models in service space. The McDonald's Touch-Order case is analyzed from business model perspective and the Media-Embedded Place business model is introduced as a U-Commerce business model for value creation in service space. The media-embedded place business model attaches auto-identification tags to tables or billboards, triggers commercial transaction through the tags, and shares the revenues and the incentives among the place owners and commerce/content providers. This paper analyzes its scenario and applications and illustrates the profitability analysis using so-called 'tag evaluation model'.
