The purpose of this paper is to analyze whether the consensus building between the information system sector and the user sector influences the satisfaction rating of the user sector. If the consensus building between the information system sector and the use sector doesn't function well, a final IT effect of the user sector cannot be expected. The WEB questionnaire data for about 10,000 people of Kanto-Kinki region executed in February 2010 was used for the analysis. I used the level of the hearing from user sector when the new information system introduced as the consensus index. It turns out that the enterprise with an insufficient consensus building had the negative effects on the IT satisfaction rating and the job satisfaction rating.

Systems approach has been generally discussed on modeling the concerned system, but rarely on the process and organization to implement the system from start to finish. Also, it has been rarely done to evaluate the system performance and to feed back the evaluation results to form the management cycle. Furthermore, the concerned system itself has been also discussed without distinction between technical systems and social systems including its technical system. Then, the systems approach is re-examined as for the enterprise system regarded as a social system.

After the East Japan earthquake, there are many supports which are manpower, material, and economic aid from the whole of Japan and overseas. However, it is said that support is not enough for victims, for example, the mismatch of the supply and demand of material supports, the distribution of the contribution delays, and unbalance of the manpower. In this report, firstly, we clarified the networking of support about the stricken area, and compare this case and 'Hanshin earthquake'. Secondly, we focused organizational networking and cooperative support. Finally, we refer to necessity of sustainable support that considered about radioactive contamination of Fukushima nuclear disaster.

When workers are paid salary from organization, inequity with other workers arises naturally. Because inequity aversion preference may significantly affect policy and contracting decisions, it is important to analyze impact of the attitudes of workers toward inequity on contracting issues. This paper aims at obtaining new theoretical insights by combing the standard moral hazard model of principal-agent relationship with theories of inequity averse preferences, in particular, inequity which exists when worker compares with ratio of the outcome to the inputs with the ratio of other's outcome to the inputs. Then we try to answer a research question ''what is the best incentive system for principal''.

There is a social dilemma in workplace regarding the contribution to a organization. Each workplace consisting of many workers, constructs each company. The society is evolved by the competition of many companies.
This paper offers a new model and helps to solve the free rider problem. The model consists of two-levels, workplace level that is modeled as a set of N-person games and social level that is in higher level than workplace.
Workers are given some strategies and the natural selection is carried out in workplace level. Similarly, companies are given some performance appraisal methods and the natural selection is also carried out in social level.We analyze the relationship between performance appraisal methods and strategies.

On April 2011, it has come to light that personal information over 77million users was leaked from the server of an amusement company. Who is responsible for that?
The purpose of the report is to examine the development of the concept of responsibility, forcing on the power of analogy. The useful analogies play a leading role to provide a general background to the incident and explore several allocations of responsibility for information control; though, it is unable to adopt an underlying reasoning.
The report concludes that the concept of responsibility is based on an ethical imagination, which possesses a main attribute for prompt action (imputability) on the information management.

Here we propose a predictive model that identifies customers who switches their brand loyalty. Our basic idea is that enumerates emerging sequential patterns and classifies customers by "CAESP". In our experiments, we select a target brand and its competitive brand, and express their discount price and a gap between them by some categories. By doing this, it can be shown not only a brand selection, but also a condition of selecting the brand. In addition to this, we introduce some taxonomy for the item. From our computational results using a practical POS data, we show that our method has good performance for the data.

In this paper, we propose an unsupervised learning algorithm to predict an anomaly detection which loyal customers lose their loyalty. A flow of our method is that finds characteristic items for loyal customers, enumerates sequential item patterns from their historical purchasing data, and expresses normal or abnormal state for the sequential patterns as a score. Then for each customer, total score is calculated as a difference between aggregated normal and abnormal scores which the customer has. When the total score is minus, we detect an anomaly. From some computational experiments using a practical POS data, we show that our method is suitable for practical use.

Despite higher levels of R&D investment, Japanese companies continue to have lower IT investments than other advanced countries. Some attribute this to the low productivity growth rate and "the lost decade". Therefore, this paper studied the differences between the IT investments in Japan and the USA by accessing an open database to show the reason for these phenomena. As a result, there were typical differences especially about the usage patterns of software investment between Japan-USA IT investments. This suggests that the rapid change emerged during IT-evolution age and Japan could not catch up the new trends. So, this study sets the hypotheses based on the findings and clarifies the mechanism to generate these differences through the verification processes of the hypotheses.

The goal of this research is to examine the factors of success with Japan's mobile industry to develop the ecosystem research model. Takeshi Natsuno, former senior vice president of NTT DoCoMo and developer of i-Mode, discussed with us that a clear and huge investment in i-Mode and e-payment technologies created the initial mobile ecosystem in 1999 in Japan. The ecosystem defined by Mr.Natsuno as a collection of roles in a collaborative balance has been established. We concluded in this research that risk-taking was the predominant factor influencing the success of the mobile ecosystem in Japan. NTT DoCoMo was the major risk-taker in Japan during this time and other players, such as mobile phone manufacturers or contents providers, could participate with little risk.

In Japan, e-books have been becoming popular and their market has been growing for the last years. There are two types of the reader; a special device for e-books and a software application in a general device. The former is popular for e-books reading worldwide. However, the e-reader has not generally been accepted in Japan, because there are not still enough Japanese contents for the e-reader. It is also caused by the difference of the publishing culture and attitude toward e-books between Japan and the others. In this paper, we survey the difference and Japanese e-book market and discuss a means to recognize the e-reader as a general tool of e-books reading.

It appears that culture in the United States has an impact on the use of social media, as different from Japan. We hypothesized that the use of social media included age, comfort with social media, time spent communicating, number of friends, and when and where users check on social media. Data was collected from 71 respondents with approximately 34% Japanese-born and 66% were American-born. It was found that younger social media users tended to have more friends and check on their social media during work and at school more regularly. More Japanese-born users stated that they "never" checked on social media during work or class. Older respondents appeared to be as comfortable as younger respondents in using social media.

We propose two approaches; One is "Problem-finding"that ask responders to check where they find as problems from sentences in a scenario. Another is "Problem-Solving" that ask responders not only to check but also propose their own solution towards embedded troubles in a scenario. We analyzed two companies along with these method then showed that there are obvious differences between them and similarity as well.
