Purpose: This study uses the protection motivation theory and information processing theory to discuss the high number of fraud phenomenon in Indonesia which causes worries to the internet users. The second problem is the large amount of information transparency in e-commerce which actually hinders the users in making decisions so it causes a negative behavior pattern, namely discontinue usage intention. Design/methodology: Therefore, this research hopes to provide insight to the online or e-commerce business community, especially for Tokopedia, to develop its business from understanding the factors influencing consumer attitude when shopping online. The sample are students from Universitas Indonesia, Institut Teknologi Bandung, Institut Pertanian Bogor, Universitas Gadjah Mada and Institut Teknologi Surabaya, with total 900 respondents. Result: The results of this research indicate that ubiquitous connectivity (UC) variable significantly affects variables such as the privacy concern (PC), information transparency (IT) and information overload (IO). PC and IO variables also significantly affect Discontinue Usage Intention (DUI). Conclusion: This study gives a new perspective that despite the phenomenon, the millennial generation especially are not entirely concerned about the privacy concern, however, this study clearly shows that the privacy issue in the digital word continues to be something that needs to be cared for.

Recently, interesting of U-city with ubiquitous computing technologies has increased and u-city services can improve people's quality of life. Among the u-city services, traffice service is actively developed in our lives. In this paper, we propose the business model and business model process in u-car tracking service. To propose the research purpose, we examined the prior business model and investigated u-car tracking information. And also, we draw scenario and used it to identify business model. To efficiently understand proposed business model, we built business model process of u-car tracking service. The results of study, we proposed business model and business model process with stakeholder, benefiter and value model. This study concludes with implications of the study results as well as limitations and future research directions.

Recently, the area of ubiquitous has gained a great attention both in academics and in business organizations as we are entering an ubiquitous society where people can interact at "anytime" and "anywhere". To preoccupy the leading status for the next generation of IT technology, many countries such as Korea, Japan, and US are concerned the ubiquitous. In this tendency, companies want to identify what factors make people use ubiquitous in order to develop the effective ubiquitous service and to supply the higher quality service. However, prior researches on ubiquitous are focused on technical area such as higher data delivery, efficient compression of images, so they do not have given companies beneficial materials for making fascinating ubiquitous services. To offer the service materials for development, from the viewpoint of the customer, important factors to use ubiquitous services are investigated in this study. Moreover, the study was progressed up to the new area of investigation how much these factors influenced ubiquitous service actual usage. To achieve these goals, Ubiquitous service adopting reflected in ubiquitous service characteristics was suggested in this study. The results of this study are as follows. First, contextual offer, ubiquity, invisibility are positively related to perceived value. Second, perceived value is positively related to usage intention but perceived risk is negatively related to usage intention. Third, usage intention is positively related to usage frequency. Based on these results, managerial implications for ubiquitous service vitalization are discussed. Lastly, the limitation of this research and further research issues are suggested.

Recently, as the development of Ubiquitous Smart Space (USS) such as U-City is proliferating, preparing a development methodology dedicated to USS characteristics has become one of the crucial issues to increase the productivity of the USS projects. However, since the legacy development methodologies such as traditional UML do not consider the critical components of ubiquitous computing space such as context-awareness, service oriented architecture and multi-agent communication, they are not optimized for USS analysis and design. Hence, the purpose of this paper is to propose a USS-sophisticated development methodology. To do so, a hybrid approach, BPR-USS for space reengineering and UML-USS by amending UML with corresponding toolkit based on StarUML has been implemented. To show the feasibility of the approach described in this paper, an illustrative example with an actual USS development project for a multiplex space in Seoul is shown.

The emergence of ubiquitous autonomic computing and network environment will change the service architecture information system which will be a new application area in SCM/logistics systems. In this study we surveyed the technical trend map of ubiquitous and its application in SCM/logistics support system design. We described the evolutional model of ubiquitous computing community for SCM/logistics system. It is consisted of three view points; self-growing, autonomic, and context-aware, which will allow the decision makers to be benefited from web and mobile technology and are useful for proactive SCM/logistics support system. Finally, we suggested a cooperative research planning for the development ubiquitous system between the government research center, university, and industry research activities.

Construction CALS has contributed much to the improvement of construction management. Recently, the ubiquitous technology brings another opportunities for expanding tile business horizon in construction. The government policies to upgrade the information technologies in Korean offer an environment in which practical application of ubiquitous becomes more practical. To maintain the level of competitiveness, construction companies need to pay attention to the chance of ubiquitous technologies. This paper introduces the research movement in the construction industry in an attempt to find out the feasibility of ubiquitous technologies such as RFID, USN, etc. The construction process, which is executed in the natural environment, will benefit from the state-of-are information technologies in terms of improved communication interface.

Recently, ubiquitous computing technology becomes available to develop advanced electronic commerce：u-commerce. Hence, it is the very time to perform feasibility analysis in applying ubiquitous computing technology, especially estimating economical value of the on-going technology. Hence, the purpose of this paper is to propose a financial value estimating methodology in performing feasibility test on ubiquitous computing technology. To do so, Black and Scholes model is basically adopted. To show the feasibility if the idea proposed in this paper, actual case study through focused group interview with those who are actually performing on-going ubiquitous computing projects. As the result, we validated the possibility of applying Black-Sholes model to assessing feasibility analysis for ubiquitous technology development with the price of call option, volatility, and the comparison with other similar technologies.
