    ICT environment is requisite for our life and business. It is important to ensure toughness and robustness of ICT systems. To ensure toughness and robustness, there are several solution such as redundant configurations, SPoF (single point of failure) less wide-are distribution. Nowaday, we must design our system to endure beyond the scope of assumption of disaster caused by southeaster sea (Tounankai) earthquake. In this paper, authors design platform to evaluate disaster tolerance of ICT system by immitating existing disaster records. They hope this platform make the system to be touch and flexible by objective evidences for complex disorder caused by disaster.

    With the development of virtual computing technology and virtual network technology based on SDN, the technology for constructing experimental infrastructures that dynamically secure a large number of computing resources provided by geographically distributed organizations using software control technology and share virtual computing resources is maturing. However, a technology for building testbeds that enables evaluation of NFV technology, which integrates virtual computers and virtual networks, in a wide-area environment has not yet been established. Therefore, in this study, we studied on the construction of an NFV testbed that enables empirical research on NFV on a wide-area distributed virtual computer infrastructure and the virtual networks that connect them. In addition, we widely developed and verified various technologies related to NFV.

    The objective of this study is to build a consumer behavior model that clarifies the causal relationship between customers' purchase process and purchase outcomes by integrating diverse shopping path data and various conventional data. In this proposal, we were able to collect valuable data through multiple experiments in actual stores and were able to build a theoretical framework and conduct empirical research using these data. As specific research topics, we proposed a framework for rigorously measuring the duration of sales promotion effectiveness based on in-store customer behavior. In addition, we were able to propose an original approach to deepening the understanding of customer purchasing behavior by estimating the psychological factors of in-store customers based on customer flow data.

    In this research, we aimed to construct an experimental programmable environment (testbed) for network by interconnecting multiple widely distributed SDN services. For the purpose, we have developed methods and conducted multiple experiments. We have built an environment connecting 10 organizations in 5 countries in total, and we have deployed AutoVFlow service that virtualizes the management of SDN environments over multiple different domains. We also evaluated the testbed through the evaluations of a high-speed data transfer system using multipath and an SDN network monitoring tool that deployed over the multiple different domains.

    In this study, a decentralized control virtual cluster system is designed and implemented. In traditional cluster systems, a centralized control structure has been accepted. In such a centralized control cluster system, all information on the structure of the cluster system, user accounts, and job queues is stored only on a master node of the cluster. This kind of structure is not scalable and not appropriate for widely distributed computing systems. In the proposed architecture, all data related to a cluster system are stored on each compute node in a distributed manner.

    The purpose of this research is to provide a model of consumer behavior which presents the relationship between consumer's in-store movement and purchasing behavior. We integrate customer's purchase history data with shopping path data which is consumer's in-store movement data in a retailer and then present various theoretical models such as customer's behavior model based on a string analysis, a time-series model of customer's movement and so on. Actually we implemented some marketing promotions in the real retailer based on our findings and achieved good sales performance. In conclusion we present a comprehensive framework of shopping path research based on these findings. We show significant implications for retail business and some theoretical contributions in marketing.
