Up to now the previous research on Smart Work has been studied in the context of the pre-adoption or the adoption stage, and shows some limitations not finding out the effort to manage change, the issues occurred in the process of adopting Smart Work, and the performance after adopting Smart Work. The period after adoption is when users continue to use ICT and intended objectives can be accomplished. Therefore, this study investigated the process that the organizations adopting Smart Work have overcome spatial and temporal constraints and the performance that they have achieved after adopting it. Though the framework integrating time-geography theory with technology acceptance stage, this research interviewed four managers of three organizations being responsible for adopting and operating Smart Work and provided its adopting process and performance of each organization.

In this paper, drawing on the boundary theory, we empirically investigated structures and factors affecting the interferences at work and nonwork which should be reduced for the work and life balance. Job autonomy and boundary strength were found to have impacts on the interferences, and role identification and permeability were shown to affect the interferences mediated by the boundary strength.

Smart Work means the work that individuals perform from a physical distances for their organizations in a flexible and innovative manner using mobile devices such as smartphones. Thanks to the Smart Work affordances with seamless access enabled by using mobile computing devices, organizations can assign tasks to employees and provide services to the appropriate customers in mobile environments. In addition, Smart Work can help improve the sharing of knowledge in the coordination and collaboration among individuals and groups performing organizational tasks. Smart Work can even help the innovation of previously unimagined services for completely new customer segments. The dramatic performance improvement is manifest by utilization of Smart Work in organizations. Therefore, the interest in the introduction of Smart Work is growing. With the lens of time-geography, this study investigates what makes Smart Work successful. This research, especially, concentrates on the infrastructure and processes for overcoming the spatial and temporal constraints in the field. A case study of the Seoul Metropolitan Rapid Transit Talk & Flash (SMRT T&F) is developed and analyzed through the framework of time-geography and communication cube, and the implementation processes and success factors of SMRT T&F are investigated.

Such convergence of previously unrelated industries raises many complex issues. This paper examines the dynamics of competition and collaboration among mobile carriers, banks and other related parties for mobile banking in Korea during the burgeoning period of mobile banking in the early to mid-2000s. This period is when the idea of mobile banking was realised in practice and a variety of the parties involved criss-crossed each other to form a network of service provision. It presents an opportunity to examine the complex dynamics of network formation for convergence services and standardization. Since convergence and standardization is a process of merging and integrating multiple players into a new network or system, it is realized through the process of interactions among the players involved. Actor-network theory (ANT) is used as an interpretive lens to analyse this process. ANT helps analyse how actors form alliances and enrol other actors, including non-human actors (i.e. technology), in order to secure their interests. By analysing three specific actor networks that emerged during a formative period in Korea's mobile banking sector, this paper shows the significance of the processes involved in developing actor networks, and especially the role of non-human actors. Given the contemporary context of the ongoing smart phone wars, which shares many of the features of convergence and standards competition, the paper 1 serves as a timely reminder of the role played by key actors and the networks they create. The paper presents some implications for technology management in convergence-and standardisation-related areas.

To explore the characteristics of MDS users, we conducted a survey with over 6000 respondents in Australia. The findings show that age is the most important demographic variable which influences the pattern of MDS use. In addition, gender and household income have a role in describing each group's consumption of MDS more precisely. We conclude the paper by presenting limitations of the study and outlining some possible future research.

With the lens of boundary theory, this paper tries to understand the nature of work/nonwork boundaries which smart work will be expected to blur. Boundary theory provides permeability, boundary strength, and interference as its key concepts and an empirical study is performed about the individual perception on those concepts. The result of the survey from telecommuters and/or smart work center users at the Company K shows that they perceive work/nonwork permeability, boundary strength, and interference are asymmetric. The result suggests that asymmetric nature of the work/nonwork boundaries should be taken into account when alternative office systems are brought into use.

Although there are many studies of standards and standardization, little is known about how international standards are set. Even less is known about how it occurs in the unprecedented case in which a developing country is actively involved in this process. In the past few years, China, leveraging the huge size of its domestic markets, has attempted to influence international technology standard setting. Standardization, especially at the international level, often revolves around building an alliance surrounding a particular technology. Actor-network theory (ANT) is a theory that helps analyze the ways in which actors form alliances and enroll other actors to strengthen such alliances surrounding a technology. Therefore, we see a fit between the study of standard setting and ANT. In this paper, we use ANT to investigate the process of mobile standard setting in an international context where firms, industry consortia, and governments collaborate and compete in complex ways. It is found that China's attempt to set WAPI as a national standard failed in enrolling other actors mainly due to the fact that WAPI was too closed a standard even for a de jure one; China did not release the WAPI security algorithm to the scrutiny of the international community.

The reasons why some proposals succeed and others fail remains unclear. The successful operation of these systems depends on the cooperation of a number of stakeholders including consumers, merchants, financial institutions and infrastructure providers. In this paper we analyse the conditions for success in terms of the benefits and costs of the system to these stakeholders. On the basis of theoretical arguments, we present two hypotheses about the necessary (but not sufficient) conditions for successful diffusion of an EPS: the distribution of costs benefits and risks among stakeholders must be mutual; and a critical mass of customers and merchants must be provided for the EPS by the financial or technology infrastructure partners. We illustrate the arguments with three case studies of recent attempts to create new electronic payments systems.
