To realize the IN capabilities it is required to introduce several new components into the existing telecommunication network. Among them Service Control Point is regarded as a keystone node of Intelligent Network. This paper discusses the architecture design and implementation of NICS(Network Information Control System), which is a combined system of SCP and SMS. Service processing aspects are discussed in detail among the functions of NICS, and service management and test environment of service logic are presented also.

The appearance and evolution of cloud service is potentially one of the major advances in information and communication technology. However, it is necessary to identify and understand the various issues of cloud service, both from the perspectives of the providers and the consumers of it. While a lot of studies such as cloud business model, profit model and technology itself are currently taking place in cloud service considering provider's aspects, there are a few researches dealing with cloud service user's aspects. This paper presents the user behavior analysis focused on SaaS users and discusses the development strategy of SaaS service based on the results of user behavior analysis. In order to analyze the user behavior, we surveyed SaaS users divided into two groups such as present and future user groups. Eventually, we proposed the SaaS prospects, development strategy and policy issues based on user behavior analysis.

Railway in Japan has been changed every apr. 20 years as follows, since the war ended in 1945. Shinkansen which was the first high speed train in the world began to revenue service in 1964, and a national railway authority was privatized segmentally in 1987, and after 20 years later from then, the ticketing service using IC card was accomplished. In this research, we review these changes in Japan in the administrative aspects on railway technology, and R & D aspects of the Railway Technical Research Institute, JR East and JR West which are railway corporations. Also we introduce the present status and future of railway technologies in Japan which railway experts diagnosed. In the twenty-first century, the needs of the times for railway have been enormously changed due to a low birth-rate, an aging society, environmental pollution and energy problems and etc. Because we have very similar problems to them like Japan, we could get lessons from Japanese cases in setting the direction for the development of railway technologies.
