It is difficult to maintain information systems safely and effectively because information systems become complicated according to the spread of Internet and cloud infrastructures. The previous definitions of operation and maintenance activities of the information systems are inadequate to stably offer the functions of the information systems to users. We consider operation and maintenance activities of the information systems from the viewpoint of IT service for users instead of the viewpoint of maintenance activities that mainly repair and enhance. We first investigate the details of the previously defined operation and maintenance activities. Then we compare these activities with ones that were defined in the IT service management. Finally, we discuss definitions of operation and maintenance activities of the information systems.

RDF/OWL languages in the semantic Web are consistent to the turns of social science. Therefore, with the gradual understanding of the world, users themselves can write down RDFs. However, the methodology for it is not yet established. We investigate what RDF descriptions are in contrast to the relational DB. RDB development is practiced in the rationalistic way by the third party in a topdown approach and users practice set operation. In contrast, in the Semantic Web users gradually describe RDF for each instance, and happen to have a large knowledge base as a result. This gradual description of the world is parallel to the idea of phenomenology. It is expected therefore that a first-person perspective approach differing from analysis is developed.

We observed while studying on IT utilization in small food manufacturers that many small manufacturers have a common issue that profit does not increase despite sales growth. Thus, we proposed a hypothesis that product cost accounting was not determined by the manufacturers and the profitability of some products were below zero. After the investigation of 15 food manufacturers in Miyagi prefecture, it was confirmed that 80% of them does not recognize the product-by-product cost breakdown structure. We also confirmed low yield products. In one manufacturer, the profit ratio was below zero for 2% of its products. We believe the visualization of product cost breakdown structure contributes to the management improvement of small food manufacturers.

New service businesses such as Amazon have a common characteristic: they play a role of platform that orchestrates and facilitates value co-creation by customers and providers. In the value co-creation process customers and providers interact each other and co-create new value, while the value orchestration platform invites customers and providers to "get on board" and facilitates the process and leaves the control entirely to providers and sometimes to customers as well.
First, we open up value co-creation process into four phases, i.e., co-experience, co-definition, co-elevation and co-development. Then, by relating it to the process model, we argue three management strategies for orchestrating value co-creation, i.e., involvement, curation and empowerment strategies.

This study aims to clarify a basis for producing enablers (ethos) of organisational knowledge creation at the production site. This research addresses the case of knowledge creation in relation to improvements on the production line in the manufacturing department of Nissan Motor Company. In order to understand such a basis, this paper also gives you the example of Seven-Eleven Japan. An original sense of values is embodied in organisations of a firm, because knowledge that is created by a firm is different from the one another firm creates and leads to superiority regarding an outcome of competition between firms. Different knowledge created by various firms results in the difference of the ethical postulate that provides what good is.

Employees learn not only expertise on a given problem but also how to solve problems collectively and collaboratively together with others through practical activities. Such an organizational knowledge-creating process is defined as a nexus of self-referential communications under an interactive environment, and the norm of the selectivity of information for communication is the origin of creativity of an employee. The norm can be cultivated by systems methodologies while replacing the philosophy of tacit knowing by long-term memory. Two examples of systems methodologies in this paper are the soft systems methodology and the design thinking the characteristics of which can be explained by double loop learning.

In Europe and the United States, the Open Government Initiative has been implemented by the three principles of transparency, citizen participation and collaboration between government and citizens. However, in Japan, only transparency, i.e.; Government data opened to the private sector (open data) has established at several central and local Governments.
In the United States, Open 311, which is the Internet communication tool for issues about public space and services, becomes popular as collaboration, instead by the non-emergency phone call 311 systems. Open 311 became possible that citizens can solve themselves by developing and providing applications to utilze these data.
In this paper, I examine the possibility of collaboration in Japan by analyzing the experiment in Chiba and Osaka City.

There is a phenomenon the blue-chip companies that have top share of the market are not able to respond to changes in the standard of value by disruptive technology with inferior performance. As a result, the company will lose the advantage in the market. This phenomenon is the Innovator's Dilemma. The causes are “Value Network" and “the uncertainty of preference for product features that consumers have". But the quantitative verification of the hypothesis is insufficient.
In this study, I reproduce the process of the Innovator's Dilemma by using Agent-based model that describe individual level interactions. Moreover, I validate the hypothesis about the cause and consider the measures the blue-chip company does not lose the advantage in the market.

In applying game theory for security, some systems are deployed and developed to allocate randomly limited security resource. Traditional evaluation for security plan, such as mathematical analysis, runtime analysis is not enough in practical situation. An effectiveness of the security plan is depending on attacker performance. In our Agent Based model, attackers act with bounded rational and criminology. Then we evaluate security plan in this model and analyze attackers' dynamically action.

It's useful for thinking business applications to identify characteristic behaviors common in a customer class from access log data. An appropriate model to solving this problem is Classification by Aggregating Contrast Patterns(CACP). But this model tends to increase number of used patterns. It makes interpretations complicated, so it's important to select necessary and sufficient patterns. In this study, we propose a method that focus on how the contrast patterns cover transactions. In computational experiments, we apply our method to an access log data of apparel site, and show the possible to decrease number of used patterns keeping predictive accuracy.

There are two types of business change such as Strategy-driven change and IT-driven change. The Enablers of business change should be different according to the reason of business change. In this research, the reasons are classified by two factors. One is the renewal of business strategy, and the other is IT roles for each company which was defined by MacFarlan(2005). The Enablers for business change are defined as the extension of the enablers for creating business value by IT in COBIT5.
This research shows that the companies which have the reason for Strategy-driven change and/or IT-driven change are preparing Enablers, performing business changes, and creating results of changes more than other companies.

However, even an individual buyer or seller can conduct persona marketing, using a blog; I have demonstrated this in another study. I have named this method "blog persona marketing." In this study, "blog persona marketing" is discussed in more detail. Particularly, this study refines the concept of the psychological transformation of the customer post-purchase, in conjunction with the "purchasing decision model."

Service Encounter is a situation where customers meet directly to services provided by companies, and the core element of service encounter is interaction between customers and employees. Face-to-face contact between customers and employees at branches or shops is the most fundamental mode of such interaction.
After experiencing face-to-face contacts with employees, customers evaluate employees, form customer satisfaction toward the services provided by employees, and develop afterwards behavioral intentions as expressions of customer loyalty.
In this study, we have conducted a web survey on customers' actual usage of banks. Using data obtained from the survey, we have analyzed relationships among customer evaluation for employees, customer satisfaction, and customer loyalty in service encounter by customer attribute-based classification.

This study analyzed the model structures that are responsible for reproducing each of the business cycles and the effect of tax reduction on GDP for income and corporation taxes by a series of computer experiment. As a result it was found that the model structures for reproducing business cycles, effect of income tax reduction on GDP are that the model includes the credit creation for investment and inefficient expenditure by the government, respectively. For reproducing the effect of corporation tax reduction, it is necessary for the model to include the executive compensation and the utilization of internal fund for investment as factors of spending accumulated earnings in addition to the inefficient expenditure by the government.

This study discusses the validity of the previous model that reproduces the business cycles and the influence of tax reduction on GDP for income tax and corporation tax from the view point of the behavior and its mechanism of macroeconomic systems. The reason for the existence of the necessary model structure in agent-based modeling is also discussed. Based on these results, it is considered reasonable that the necessary model structures responsible for reproducing each of the macroeconomic behavior can be clarified by a series of controlled computer experiment in which only one factor is changed with other factors being held constant, through the procedure of which the mechanism of the macroeconomic behavior can be also elucidated.

Binominal logit model is probabilistic model of non-linear type and model parameters are usually estimated by maximum likelihood estimation. In maximum likelihood estimation, parameters are estimated to fit whole data maximally but does not necessarily reflect characteristic of each data. On the other hand, it is natural to think that the management condition of companies varies according to the qualitative factors such as the length of management or the ability of managers even if they have same financial settlements.
Therefore, in this study, we try to improve prediction power of credit risk model by supposing prior distribution for model parameters and estimating parameters by hierarchical Bayesian method.

Most investment theories assume that the termination time of an investment is known at the beginning, which is not true in general, most investors do not have a lear termination time in mind when they begin an investment. Our study is to provide a framework for analyzing investments in such situations. We will introduce the notions of period return and period risk, and the measures for these notions.

We introduced some word plays among teacher and 1
st grade students, in order to interest in leaning contents. We defined “Info-Sensitivity"as the number of the answers operationally.
We examined the correlation between “Info-Sensitivity"and the results of their examination. By this analysis, we considered the relationship between the size of their vocabulary and the degree of their learning results.

The number of workers in their 40s and 50s burdened by caretaking chores in their families is expected to increase due to the aging of the baby boomer generation. They are likely to find their regular jobs exhausting, because the ending time of the caretaking is unpredictable.
Many workers with strong experience and skills are likely to quit their jobs. The sudden departure of a worker may make it difficult for a company to continue its business. A company should understand the nursing care burdens on its employees, prepare a practical system to retain its employees, and develop human resources. This study considers a database for visualizing nursing-care burdens and working conditions for employees.
