When students read textbooks in the classroom, they usually apply active reading. Our previous study was to show the relation between the total number of comments inserted by students into their digital textbooks and their grades at the end of course. In this study, it surveyed what difference there is the note-taking behavior between on paper and PC by students who have experience taking a note on their digital textbooks during the courses.

We developed an automated tool for generating student 's university co urse schedule considering their field of expertise and weakest domain using this technique. We have employed our criteria whether the relevant student is superior or inferior to such subjects by means of his/her history of credits. In other words, "difficulty" about a subject can be defined as the relevant student has obtained according credit(s) or not.

Variation of typesetting layout was investigated for series publications such as "Bunko" by measuring spaces between characters and lines over years. Nineteen types of series publications among the Aichi University Library holdings had similar character sizes, character space and line spaces. The character density of books of Iwanami Bunko decreased around 2007. A novel, "Norwegian Woods" by Haruki Murakami published in several formats showed the hard cover version had the least dense. Layouts of several ebook apps had similar character space/line space ratios for Kinoppy (iPad and HTC) and iBunko (iPad-gothic, HTC), but those for iBunko (iPad-mincho) and GARAPAGOS (HTC) were less dense.

We analyzed the rate of Japanese journal articles archived in institutional repositories based on the data of Society Copyright Policies in Japan (SCPJ) database and CiNii. As a result of analysis, only about 0.9% of Japanese journal articles published during 2000-2009 were archived in institutional repositories. The archive rate was low in all fields. While articles published in Green, Blue or Yellow journals were more archived than others, the archive rate of those was only about 1.3%.

With progress of the digitization in the local government, the digitization of the information that the local government holds advances, and some of which are to be published on the Web site of the local government. However, under the present conditions, to re-use the information that is published is not assumed. It has remained in that information to hold it being merely computerized. In this study, it focuses on the local government public relations paper and confirms the present conditions and issues of archiving of information that the local government holds.

During the Great East Japan Earthquake, communication via Twitter attracted a great deal of attention. The aim of this paper is to quantify the actual level of Twitter-based communications related to the earthquake from data for 77 hashtags that was collected during a three-month period following the Great East Japan Earthquake. From some basic statistical analyses of the data, it is clear that, although there were a few earthquake-related peaks during April and May, the use of most hashtags gradually decreased following the earthquake. Utilizing NLP technology, differences in topic across the various hashtags were analyzed. Moreover, employing methods of social network analysis, the monthly changes in the relationships between the hashtags were analyzed and the organizational trends for each hashtag and the shifts in major topics were also extracted. Based on those analyses, some proposals are stated for the use of hashtags at the time of natural disasters.

Information has many ways to use, and the kind of information and quality of information changes with usages. For example, the bestseller information is important, and the long-term seller information is important as well. Why? The reason for this is that the long-term seller information is used many users for a long time. As opposed to this, there are many access technique of the bestseller information, but there are few access technique of the long-term seller information. As a result, it is difficult for us to access the information that is used for a long time but it isn't the bestseller.
Therefore, we proposed a general idea that is long-term degree, and we developed the system that selects and gets the long-term seller information.

The condition with which object is controllable is made clear from the dynamic nature of rationality and the object with this condition is given the name “system”. From the control on system the following things are made clear. The control mechanism of machine, human's recognition during design and human's behavior by recognizing demand of age are each feedforward and feedback control.
Moreover in design process problems solving are performed diffusely between these time sequences inside of human's recognition and also in recognition process of demand of age social insight forces being able to know it and hiyarihatto phenomena being able to know alarm appear diffusely between these time sequences outside of human's recognition.
At last it is shown that one current of age about control can be composed of these three kinds of control. Namely the starting of this current, the terminal of it and the order these three controls appear are important and this current means the direction which conquests the tragedy of brainwashing and has possibility going toward the control of nature.

For storing and managing enormous data, NoSQL databases have been employed recently on behalf of RDB since NoSQL is high-performance and scalable. However the differences of the data structures and the manipulation languages give the developers pause in making the shift to the systems using NoSQL. In this paper, we report a converter which takes an SQL statement as input to generate an equivalent code of target language of NoSQL. MongoDB and HBase were selected as the target languages while we attempted to implement an SQL analyzer and coordinate the code segments of the programming languages. As the result of the evaluation experiment, 13 MongoDB queries and 9 HBase ones were derived from 32 example SQL statements.

The decision making process that precedes the introduction of new energy system should look for a balance among human security , environmental safeguards, energy security, proliferation risk, economic risks, etc. For nuclear energy, in particular, the Fukushima Daiichi nuclear disaster has brought to fore the strong need for transvaluation of nuclear energy technology. Here, we employ bibliometrics to identify the major trends and issues of social-scientific study for nuclear energy technology by using International Nuclear Information System (INIS).

In this paper, we investigate the performance of types of weighted citation network for detecting emerging research fronts by a comparative study. We employ some measures for evaluating the research fronts to weighted citation networks. For instance, average publication years and similarities of keywords are effective measures to detect research fronts. By introducing these measures as weights of citation networks to the citation network, we can detect research fronts and promising fields compared with the non-weighted citation networks. We perform a comparative study to investigate the performance of type of weighted citation networks for detecting emerging research field. Especially, we evaluate the performance of each type of weighted citation networks in detecting a research front by using the following measures of papers in the cluster: visibility, measured by normalized cluster size, speed, topological relevance, and density.

ISHIHARA Yoshiro, who was held as a detainee in Siberia for eight years after World War 2, was an educated and intellectual poet. This research on historical thought would verify relations between educational intelligence and transfer of experience in ISHIHARA's poetry by using method of data mining. In his poetry, the researcher could see many vocabularies, especially first personal pronouns. It would mean ‘the modern Japanese's study of self' and sympathy which is an important element of poetry. The research would show that using data mining is valid attempt and leads new readings for ISHIHARA's poetry.

Recently, the development of new drugs for lifestyle diseases has been much expected due to the increasing number of patients with lifestyle diseases and the high risk to death. In this paper, based on the extraction method of disease-associated genes from the biomedical literature, we propose a method that extracts new candidate drug targets for lifestyle diseases with less side-effects by constructing a gene ontology that describes relationship to causal lifestyles. Furthermore, we evaluate the effectiveness of our method using known drugs.
