The auther released at the 24th annual meeting of the Japan Society of Information and Knowledge the tested result of the hypothesis that multiple debts which mankind had burdened had been cancelled by the sacrifice of Jesus. This time we made it clear that the sacrifice of Jesus is the large debts mankind has burdened to Jesus and we should go ahead into the direction to settle this debts to Jesus. In this direction the victims of atomic bombs in Hiroshima and Ngasaki have as much essential meaning as the sacrifice of Jesus for mankind in value. Moreover a variety of issues regarding the natural environment and security indicate that mankind has burdened debts also to God who has created and possessed the natural environment and had given mankind the sovereignty and it is involved in the upper direction to settle the debts. Rationality found in retributive justice of the direction indicates that as Jesus being God had appeared in this world as a man, we ,mankind, must grow to Jesus being God spiritually and that is our goal.

In the school education, teachers are practicing group-reading activities with adolescents for developing the reading comprehension, linguistic expressive ability and communication ability of adolescents. On the other hand, it is also important that the support in adolescents' independent group-reading activities as development of the independent learning attitude. For considering about an important matter of adolescents' independent group-reading activities, we selected “Bibliobattle” as one kind of group reading activities, and analyzed records of Bibliobattle events in Japan.

In this paper, as a part of text mining, we attempted to approach “Waka”, which is representing medieval literature. The target of analysis is eight imperial-commissioned waka anthologies which is called “Hachidaishu” from the middle of Heian period to the early of the Kamakura period. We performed a quantitative analysis using morphemes and examined the difference of “Hachidaishu”. We investigated as a method of analysis, using statistical difference of part-of-speech usage rate among “Hachidaishu”, especially seasonal poems and love poems, using the relationship between noun rate and MVR performed by Yumi Fujiike. Then, we tried to discriminate by using the Naïve-Bayes method which is one of machine learning methods. The result was that it was difficult to discriminate using the data of Waka overall. However, the discrimination of “Waka” by genre-specific data such as seasonal poems and love poems of “Waka” has also quite high one especially in “Gosen-Shu”. Therefore, it seems that“Gosen-Shu” is a little heterogeneous existence among “Hachidaishu ”.

This paper discusses different aspects of whistleblowers and how ICT can encourage whistleblowing. Reporting a misconduct at work should never be underestimated as a little spark can grow to a flame in a short time. There is a positive impact of using ICT framework when dealing with whistleblowing at work. The act presented in the paper consists of six components, the first component is creating an online reporting tool that streamlines the allegation process by providing a single reporting mechanism for whistleblowers with possible anonymous reporting functionality. Second is stating that any act that harms the organization considered a malpractice and will be treated seriously with complete discretion about the whistleblower. Third is the organization is vowed to protect reporters and treat information with great confidentiality while conducting inspection process through the online reporting tool. Fourth is penalties for claiming a false allegation. Fifth is awards for reporting depending on reflection report from inspection committee personnel who are utilizing data from the online reporting tool. Finally, clear way of conducting interrogation with stakeholders with utmost respect and value their privacy.

Throughout information processing education provided for the first-year students of Faculty of Systems Engineering, Wakayama University, they did not adequately take an opportunity for review. To solve the problem we adopted e-learning which one can use anytime and anywhere and we constructed a system that supplies quintuple-choice tests about what the students learned in class. This system also helps the teachers discover inappropriate or unnecessary questions by means of the visualization of response variance. An evaluation experiment showed that a faulty question brought a lower accuracy rate while it took a longer time for the choice.

This research aims at investigating how types of books and reading purpose affect consumer’s preferences. We conduct an online questionnaire that shows the same title of books in print-book and e-book for participants, and changes factors of comparison, such as “the types of book”, “with or without afterword”, “with or without cut”, and “functions of e-book”. From the results, more participants prefer a print-book in novel tasks than an e-book, while more participants choose an e-book in how-to book tasks than a print-book. This results indicate that different types of books and reading purpose may affect consumer’s preferences, as the importance of factors of comparison changes when they compare different types of books and their reading purpose.

The purpose of this study is to discuss an adaptable way of installing telework in Japanese companies, focusing on the latent internal factors and the existing IT tools. Telework has become a realistic way of working thanks to technological progress, yet it has not been adopted widely. We conclude that step-by-step ways of installing are important in Japanese companies from the results of investigation conducted in two companies with different degrees of telework maturity.

In this paper, we describe a music distribution service using near field communication. Recently,sales performance of music contents is said to be decreased, but on the other hand, demand for music events is increasing. While society increases any other entertainment than music and opportunities to touch music are relatively reduced, the demand for music itself is not decreasing. In our system, we try to distribute music titles and contents by wireless communication between music players from a short distance and to promote the spread of music.

In this paper, we describe a social networking service (SNS) named “Favorything” that opens the users' favorite things to the public on the Internet and connects with others. Recently, many SNSs are widely spread, but there are no services specialized for users' ownership. In our service, users with same preferences focus on their own "things", which are added value as a new business model. We released this service on the net and show examples actually used.

A lecture mirroring a lecturer's monitor on a projector screen is relatively common in the field of education. However, when a lecture talks about to the projector screen, the lecture can’t do the computer operation involving complex mouse action. Therefore, in this study, we propose a contact detection method for a pointing stick to realize a direct computer operation on the projector screen.

I have printed out models of the world heritages in Sri Lanka with a 3D printer by using the ALOS global digital surface model (DSM) "ALOS World 3D – 30m. Noting that Sri Lanka under such remarkable economic and social development also has many historical and cultural sites, we explored the feasibility of modelling the world heritages by using this data. The ALOS global digital surface model is open to the public at free by JAXA for the sake of the scientific research fields and utilization of the geospatial information. This is a data set of 30m (1arcese) resolution of the global digital surface model (DSM) by the Panchromatic Remote-sensing Instrument for Stereo Mapping (PRISM) mounted on the advanced land observing satellite "ALOS". This data set was created based on the DSM data set (5m resolution) of the "world digital 3D topographic data", which has the world best accuracy at present as a global-size elevation dataset. This data in the form of TIFF images is converted from the 2D images to 3D STL data for 3D printers by a program. In doing this, firstly, the portions necessary for the world heritages are extracted from the TIFF images stored at 3600× 3600pixels with 16 bits. Then, the extracted images are converted into the STL data, which is then printed out by the 3D printer. The output data is exhibited and released on Web.

In recent years, utilization of big data and open data has been promoted, and many organizations including the national government, local government and other organizations are working on opening and utilizing open data. These disclosed data formats are still many files in Word, Excel and CSV format. The data utilization that "It is machine-readable and second-hand use of data is possible without spending a lot of manpower" clearly stated in the 2012 e-administration open data strategy formulated in 2012 is not yet reached. If many disclosed data can be easily converted to RDF format,mechanical linkage of multiple open data becomes possible and it becomes possible to promote utilization of open data. In this research, we focused on the vocabulary that corresponds to the predicate of the RDF form, and experimented about the approximation of the vocabulary by utilizing the neural network called Wrod2Vec in order to share the vocabulary. We also propose a method to convert common Open Data to RDF format file by using vocabulary based on common vocabulary recommended by IPA to share common vocabulary.

A program that works as a Docker container and generates information retrieval services was developed. When one sends documents, the program makes Dockerfile and other files which are a source of Docker containers for an information retrieval service. By using this program, the registered documents are indexed and we can afford a full-text search without releasing the possessed contents to the public or uploading them on cloud services. Furthermore we made evaluation experiments with more than 60,000 blog articles on disaster prevention.
