As smartphone users grow, mobile operators are trying to standardize and commercialize Rich Communication Suite (RCS), which is a next-generation messaging service, so that it can replace legacy messaging services. However, it is not enough to spread RCS widely to the users only by publishing an RCS app. To increase the use of RCS, a web-based open API for common RCS capabilities is needed. By using the API, Internet-based developers can create applications that make use of the RCS capabilities with less effort and time. This paper proposes a lightweight Comet-based open API to allow mobile operators to expose useful information and capabilities to application developers. The system architecture of the open API framework and call flow between relevant nodes are defined. In addition, examples of protocol translations on the framework are provided.

The major worldwide communication network operators have designed and are building up the NGN with various network capabilities, which conventional Internet do not have. The open network service model makes these network capabilities available to the third party of the value added service providers through the standardized API providing users with more intelligent and enhanced services. This paper proposes the open network service model as NaaS (Network as a Service) and examines service models of several levels. It is believed that these efforts presented in this paper will make the network operators expand their service ranges through the opening of invested network resources producing more various communication services for users.

Demand for new information services is ever increasing as information technology advances in an unprecedented pace. Capabilities of information technology to overcome the time and space limitations enables efficient storage and processing of a large volume of data shared by many users in geographically dispersed areas. As the users ask for more useful information services, it is necessary to develop information services tp meet the needs of users. Enhancing information services is also necessary to cope actively with the pressures to open the information service is also necessary to cope actively with the pressures to open the information and telecommunications market as the level of Korean information services industry is still in its infancy. Value Added Network(VAN) services have a tremendous growth potential and its economic and social impact would be great as the information society matures. This study suggests a direction for the development of value added and new-media services based on the survey of individual and business users of information services.

The present study is a review to determine by what bodies and through what mechanisms the national industrial information policy is implemented and administered, that is what is its content and how it is linked to industrial and technological needs in the field of industrial firms. There are lacking essential capabilities required to transfer industrial information and to channel it to ultimate users. It is not possible to identify users' information needs adequately, to acquire pertinent information, to adapt it to prevailing conditions, to disseminate it to those who need it. Various organizations work to meet the specific information requirements of industry. These organizations include governmental agencies, industrial associations, research institutes and information centers. They have, however, developed independently without liaison among them. They may be some unnecessary duplication in some spheres and inadequate facilities in others. A n.0, ppropriate institutions which provide industrial information would be industrial associations, industrial research and development institutes. They serve as a coupling mechanism between industry and the existing information facilities.

Recently, the notion of "increasing returns" has been popular not only in academia but also in industries. This notion has been drawn from prior research on network effects, which showed that the market evolution would lock in to a dominant technology. However, the long history of technological change has rarely shown the possibility of lock-in to an inferior technology. How could the market with network effects make transition between incompatible technologies regimes by escaping the lock-in? This paper analyzes the effectiveness of R&D and technological choice to investigate the sources of the dynamic capabilities in the presence of network effects and uncertain technological progress. Why does the market sometimes work against a radical technology, and why, at other times, does the market operate in favor of it? This study is to address this question by modeling the situation of two competing technologies in the presence of network effects. The numerical analysis indicates that the evolution strategy of compatibility is more likely to increase the chance of firm growth when a majority of customers are not power users or when demand for an old technology has been escalated. But when there are a substantial number of power users or when a new technology emerges before such an escalation of demand, the revolution strategy of compelling performance is more likely to be effective. The result suggests a potential mechanism for overcoming the lock-in problem. When the market exhibits some inertia to an obsolete technology, which is reinforced by the increasing customer value with respect to backward compatibility, the survival of a new technology depends on power users. When many power users are cultivated by firms' technological efforts regarding the new technology, the market is less likely to lock into an obsolete technology. Indeed, in the workstation market, where power users characterize much of the demand, innovators like Sun successfully switched to the RISC architecture.

Increasingly, Grid technics are developed and demonstrated widely. These days, a point to be considered is that clients use Grid resources more easily. Grid Portals, based on standard Web technologies, are increasingly used to provide user interfaces for using Grid resources. But, due to lack of delegation capabilities in using Grid resources through Grid Portals, it is requested of the security mechanisms. That solution is to using Myproxy Server. Myproxy Server allows Grid user to use Grid resources being interact with Grid Portals. But, while users log in Grid Portals, we are faced with over the overlap of users credentials. This paper describes relationship between Portals and Myproxy, and proposes the way to solve the problem of the overlap of users credentials.

This paper touches the limitations of existing theories related to technology acceptance, which mainly focus on users' perceived ease of use and usefulness, and proposes the role for sensory capabilities and enjoyment in understanding smartphone use. Furthermore, we develop a model that explains smartphone usage and intention to use it for a task and analyzes 442 questionnaire survey responses of smartphone users. First, perceived usefulness, perceived sensory capability, and perceived enjoyment influenced smartphone usage. Second, we found that both perceived usefulness and smartphone use were significantly associated with users' intention to utilize the smartphone for their job-related tasks. Finally, both perceived sensory capability and enjoyment were found to be more powerful factors than ease of use in explaining smartphone use. From the study findings, implications and future research directions are also discussed.
