The auther published at the 23th annual meeting of the Japan Society of Information and Knowledge that we could find the current of justices demanded by God and of reality corresponding to it referring to a Bible. But this current of justices is on the assumption that debts loaded human were cancelled by the substitution of Christ. Then I considered how we could verify that this was fact. I investigated how a fact C influenced on the history of human when a fact C occurred under God's intention A at time B. Consequently I found historical traces corresponding to those influences. And I made clear that in God's intention there was need cancelling debts loaded human by the substitution of Christ and in human society there was motive killing Christ by a cross and there was possibility which God's intension realized.

To cope with many difficult problems of the earth independently and actively, with which we are faced in this 21 century, we have to change over the paradigm of our daily life to adjust ourselves better to the rule of the natural world, and have to realize such activities as Cognition, Thinking and Action, Evaluation and Emotion self-conclusively that are neutral to natural-selection because of high degree of freedom.
It may be the condition for adapting ourselves to the rule of the natural world, to realize Fusion at the critical point between complementary vectors as part/whole, depth/width, exclude/include, competition/cooperation, and so on, even if they are apt to be regarded as paradoxical binomial conflict at a first look.

Current industrial society is a state of the trilemma of environmental, social and economic. The human race is expected to be 10 billion people in the 22 century. However, the Earth's resources are not only of resources cover it.
Trilemma of the solution, already without, was and remission measures. I have proposed a reduction in the rate of population growth and industrialization rate. It is a "biological and model to preserve the human race" "model to preserve the language and culture" Premise to develop.

In this paper, we measured the frequency of the binding particle which constitutes a "Kakarimusubi" in the several medieval literature and we tried text mining with it. The statistical method, test of proportion, principal component analysis, cluster analysis, discriminant analysis were carried out. In the established theory, "Kakarimusubi" is declined over "Muromachi" era from "Kamakura" period. Because "Bushi" became to have a great power, and didn’t use "Kakarimusubi" which was the word of aristocrat. In this paper, the trend can be seen chasing the era. Further, we investigate the difference between the work by each chapter’s frequency of the binding particle. As a result, a different tendency is seen between "Uji Shūi Monogatari" and the other literatures.

The possibility of the text categorization using radicals of Kanji (bushu) has been examined in Japanese texts. Kanjis in the texts were converted into the corresponding radicals. The frequencies of the radicals, as well as frequency orders are acquired with different subject categories of texts. The same tendencies were observed for the titles and for the full text of the articles. The "Top 7 Radicals" frequented in all the categories, their order however differed by categories. The typically frequent radicals related to the subject fields were observed in subcategories of industries. The frequency orders of radicals were stable within a journal, when analyzed by whole issues of scientific journals, whereas it varied when analyzed by individual articles. The radicals seem to be applicable to the bulky text categorization.

The paper reports that book purchasers suppose what gain from books under the situation where contents of e-book and print book are not identical. This report examined what is purchasers’ point of focus at the time of purchase along with their purpose by using stories on buying books and checklist of criteria.
We recruited 14 university students. As a result,the price was the only criteria selected by 5 or more participants in all the 4 tasks.In general, we observed that different genres of books and reading purpose resulted in the change to participants’ point of focus.

Nowadays the regional gaps between the metropolitan area and the local areas in Japan have expanded. We can also guess the importance of this problem from the situation which “Headquarters for Overcoming Population Decline and Vitalizing Local Economy” has been established in the Cabinet and various efforts for that have been made. Gini coefficients have often been used when the regional gaps are analyzed but, in many cases, the Gini coefficients focus on incomes of people. Then we have developed a new model of Gini coefficients which focuses on the number of public facilities to analyze the regional gaps from the viewpoint of public infrastructure. Thus it has turned out to be no regional gap from the viewpoint of public infrastructure around principal stations as a result of the analysis conducted on the basis of the data concerning the number of public facilities around principal stations of 47 prefectures by using the model.

Media mix is a media strategy conducted multidirectionally for one content, such as using visual images and music. As one of the successful cases, Yo-Kai Watch and Pokemon (in Japanese games) are reported on the website of the education ministry. Although the effect measurement approach of the media mix is also suggested, very few previous researches have been conducted to measure the effect of the media mix in chronological order through individual media strategies. Thus, this study proposes the effective measurement approach (model) of the media mix in which the multiple linear regression analysis is conducted by holding the Yo-Kai Watch as an example and setting the number of sales of its game as an objective variable while setting the implementation status of the media mix strategy as an explanatory variable in chronological order. As the result of analyzing the sales data of Yo-Kai Watch game between July 2013 and July 2014 using this model, it was suggested that the media strategy was the most influential factor in its sales.

The tone changes in mass media before and after the great east Japan earthquake on social problems were clarified quantitatively based on articles in newspapers about energy problem. Articles about energy problem were extracted from articles in two nationwide newspapers since 2010 to 2012, and frequently appeared words and co-occurrence patterns before and after the earthquake were analyzed. As a result, it is clarified that renewable energy was told form the viewpoint of ecology before the earthquake, but that was told from the viewpoint of power supply after the earthquake.

Interest of the child appears in the children's questions. We have developed a social picture book recommender system "Pikubuku", which can recommend the picture book to the children's questions. In this paper, by adding an automatic recommender function to "Pikubuku", we tried to improve the recommendation rate, and to encourage a lively picture book recommendation. We report the results of user experiments for 14 sets of parent and child.

In recent years, the electronic media are increasing. Many devices can be seen so that for a researcher to be able to access the resources, such as web seminars by the link resolvers and venders. On the other hand, although the university library takes charge of the user education of the database, the latest trend is not clear. This study aims at examining how the database guidance, and the user education are performed in the academic library in Japan, through a website analysis. The Results of this study indicated that the difference can be seen by the scale and the style of the university.

Cognitive diagnostic models(CDMs), which are psychometric models, have become famous because we can assess students' knowledge status with these models. We can use these models with Mplus that is statistical analysis software to deal with latent variable models. However, it is laborious and difficult to describe a code for CDM analysis. In this study, we developed an R script to support executing CDM analysis with Mplus. We need only a Q-matrix that represents relationships connection test items and cognitive attributes to generate an Mplus code. We confilmed that our R script generated an Mplus code for CDM analysis.
