<p>Due to the widespread popularity of smartphones and social media to people specially to youths, the risk and danger in people's life is increasing. This research focused on 'prostitution' which has become a serious social pathology problem in recent years, analyzed the use of hashtags attached to problematic postings on Twitter using quantitative text analysis as one factor contributing to the issue. From the results, it was possible to classify seven groups with hashtags of high frequency appearance. Among them, it became clear that the co-occurrence relation between "area names" and "prostitution (indirect expression)" is especially strong. Such findings can be expected to lead to effective preliminary detection in cyber patrol.</p>

Interprofessional education (IPE) for healthcare professionals is important in Japan because of its rapidly aging population and increasingly complex healthcare needs. However, no tools have been validated in the Japanese context to evaluate healthcare professionals' attitudes towards, or readiness for, IPE. The professional version of the Readiness for Interprofessional Learning Scale (RIPLS) with 23 items was selected for cross-cultural adaptation because it has been widely used internationally and a Japanese edition of the student version has already been developed. We followed a guideline for cross-cultural adaptation and subsequently conducted factor analysis with 368 responses from over 16 professions. Face and content validity was confirmed through the translation process. We obtained four factors with good internal consistency (Cronbach's alpha > 0.7). These results were similar to those of the original UK study, apart from one factor being divided into two different factors in this study. Studies are required to further confirm the rigor and generalisability of the results; however, the Japanese RIPLS can be used to evaluate healthcare professionals' attitudes towards IPE, which can eventually lead to a better IPE development for healthcare professionals in Japan.

<p>In Japan, social media use by political parties and candidates during election campaigns had long been prohibited. However, the rule was changed in 2013 and the first "House of Representatives election" introduced a new rule that was conducted in December 2014.</p><p>At the same time, two newspaper companies published articles which focused on the candidate's twitter usage. However, the process of analysis was unclear and the conclusion was unreliable. This research further seeks to confirm critically the results of the twitter usage analysis provided by the newspaper companies by using original sampling data. Especially, this research tries to check the validity of the following research question : Were the LDP candidates avoiding the topic of "abenomics" ?</p>

In this paper, I discuss about differences of word-of-mouth platforms. Preceding studies had clarified many things. But, they only had paid attention to single platform. I focused on relation of platforms, and compared "amazon" and "rakuten-books" as word-of-mouth platform by text-mining. In the result, two platforms had remarkable differences.

&ldquo;Telework&rdquo; is a work style that is free from restriction of place and time by using ICT. It is advantageous for us to adopt telework as a risk management strategy for an emergency, since it allows us to work at home rather than having to travel to an office.<br>This research aims to investigate the advantages and issues surrounding telework with particular reference to the confusion in the traffic network after The Great Eastern Japan Earthquake in 2011. A large-scale Web questionnaire was carried out, and four implications were drawn from the results.<br>1. Many workers went to their company even though the traffic network was thrown into confusion.<br>2. About one in ten companies were using telework.<br>3. The experience did not contribute to other case of confusion.<br>4. Telework may have changed workers' attitudes and reactions toward the confusion in the traffic network.

In the present study, it paid attention to the word of mouth marketing guideline that The Word of Mouth Japan Marketing Association had announced on March 12, 2010. And, examined how this guideline had effectiveness. Firstly, the definition and the previous work about the word of mouth marketing were confirmed. After that, picked up the guideline and analyzed cases that work or not. As a result, it reached the conclusion that the effect from the viewpoint of the consumer protection is limited. Finally, it paid attention to the case of penny auction. If stealth marketing is suspected, the guideline had not functioned effectively. As the reason, the guideline has stopped at moral regulation, and it was mentioned that things, such as a punitive clause or a research function, do not exist like U.S. regulation.
