歯科医院のウェブページの訪問数がその歯科医院の新患数にどのように影響するかを調べる目的で，ウェブページで得られる情報をもとに歯科医院の現状を調査した。指定ページのアクセス等に関する様々な情報を集計する

システムで，2012 年3 月から2014 年2 月までの2 年間の「ユーザーサマリーレポート」から，ウェブページの訪問数（セッション数），訪問者数（ユーザー），平均セッション時間，ウェブページの最初のページしか見なかったセッションの割合（直帰率）それぞれと，K 歯科医院のウェブページを見て来院した新患数との関連を調べた。

その結果，2013 年3 月から2014 年2 月の間のウェブページからの新患数とその6 ケ月前である2012 年9 月から2013 年8 月までの間のセッション数には負の相関が見られ，K 歯科医院のウェブページを始めた当初はそれがきっかけで来院した新患数は増加しているが，時間が経つにつれて，セッション数とユーザー数は増えているにもかかわらず，新患数は却って減少していた。

また2012 年9 月以降，携帯機器からのアクセスの割合が増加し，一方でデスクトップパソコンからのアクセスの割合が減少していることと，直帰率が増加し，平均セッション時間が減少していることが明らかになった。

This report presents a new quantitative research method of investigating the English-learning behavior of students in a Web-based learning environment. Studies of computer-assisted language learning and their transition from classroom- to Web-based practices testify to the wide use of Web-based technologies. However, to the best of the author's knowledge, no accessible and practical methods have been identified that investigate the Web-based learning behavior of students. To address this need, this study performs and tests a new quantitative research method that combines access-log analysis and social-network analysis. To investigate the efficacy of the proposed research method, a Web-based learning environment was designed and integrated into in-class lessons. The in-class lessons were held once a week for a period of one and a half months, and 16 university students participated. Their access-log data on the Web-based learning environment were collected and analyzed, which allowed their learning patterns to be identified. In addition, their use of the Web-based materials was visualized to aid in understanding the topology of the Web-based learning environment. The results are used to determine the efficacy of the proposed research method.

Web tracking is widely used as a means to track user's behavior on websites. While web tracking provides new opportunities of e-commerce, it also includes certain risks such as privacy infringement. Therefore, analyzing such risks in the wild Internet is meaningful to make the user's privacy transparent. This work aims to understand how the web tracking has been adopted to prominent websites. We also aim to understand their resilience to the ad-blocking techniques. Web tracking-enabled websites collect the information called the web browser fingerprints, which can be used to identify users. We develop a scalable system that can detect fingerprinting by using both dynamic and static analyses. If a tracking site makes use of many and strong fingerprints, the site is likely resilient to the ad-blocking techniques. We also analyze the connectivity of the third-party tracking sites, which are linked from multiple websites. The link analysis allows us to extract the group of associated tracking sites and understand how influential these sites are. Based on the analyses of 100,000 websites, we quantify the potential risks of the web tracking-enabled websites. We reveal that there are 226 websites that adopt fingerprints that cannot be detected with the most of off-the-shelf anti-tracking tools. We also reveal that a major, resilient third-party tracking site is linked to 50.0 % of the top-100,000 popular websites.

Background & Aims: With the development of radiology, the demand for medical physicists is increasing, and the training of new medical physicists is becoming a necessity. Although a few questionnaire surveys regarding medical physicists and medical physicist training courses have been conducted, no survey reports have yet been conducted on examinees. This study is the first survey of general examinees.

Methods: Gunma University has a webpage for test preparation, and we conducted a survey on examinees using this page, through a questionnaire and access analyses.

Results: Approximately 80% of the users qualified as technologists. Considering the percentage of users by region, the number of medical physicists and accredited facilities were strongly correlated. The proportion of females was extremely low. Exam papers on “science and technology” and “radiation physics” were accessed more than those on “medical and biology” field. Thus, physics may be a shortcoming of many examinees; science and engineering majors were less likely to take exams and have lower pass rates.

Conclusion: Recruitment and provision of learning environments for science and engineering graduates are required. To increase the number of students, while improving the quality of medical physicists, it is necessary to investigate current conditions of students in greater detail.

Privacy issues due to web tracking are a continuously evolving problem. One tracking method utilizes third-party cookies. This method analyzes user behavior and interest on the Web by sharing cookies with third-party vendors such as analytics and advertising brokers. Several regulations on third-party cookies have been considered by countries and browser vendors to address privacy issues due to such excessive web tracking. However, third-party vendors continue to track users with new technologies such as link decoration that embeds cookies in URLs and CNAME cloaking which tricks browsers into treating third-party cookies as a first-party. In this paper, we analyze cookie sharing by link decoration and CNAME cloaking and reveal their privacy issues. In addition, we reveal new security risks emerging from these technologies.

Background: The Physiotherapy Evidence Database (PEDro) may help users to overcome some obstacles to evidence-based physiotherapy. Understanding the extent to which Japanese physiotherapists access research evidence via the PEDro website may suggest strategies to enhance evidence-based physiotherapy in Japan. Objectives: To quantify usage of PEDro in Japan, to compare this to usage in other countries, and to examine variations in PEDro usage within Japan. Design: An observational study of PEDro usage with geographic analysis. Methods: Data about visits to the home-page and searches of the database were recorded for 4 years. These data were analysed by each region of the World Confederation for Physical Therapy, each country in the Asia Western Pacific region, and each prefecture in Japan. Results: From 2010 to 2013, users of PEDro made 2.27 million visits to the home-page and ran 6.28 million searches. Usage (ie, number of searches normalised by population) was highest in Europe, followed by North America Carribean, South America, Asia Western Pacific, and Africa. Within the Asia Western Pacific region, population-normalised usage was highest in Australia, then New Zealand and Singapore. Japan ranked 10 among the 26 countries in the region. Within Japan, the highest population-normalised usage was in the Nagano, Kumamoto and Aomori prefectures, which was ten-fold higher usage than in some other prefectures. Conclusions: Although Japan has higher PEDro usage than many other countries in the Asia Western Pacific region, some prefectures had very low usage, suggesting that evidence-based practice may not be being adopted uniformly across Japan.

This study developed a snow load alert system, known as the “YukioroSignal”; this system aims to provide a widespread area for assessing snow load distribution and the information necessary for aiding house roof snow removal decisions in snowy areas of Japan. The system was released in January 2018 in Niigata Prefecture, Japan, and later, it was expanded to Yamagata and Toyama prefectures in January 2019. The YukioroSignal contains two elements: the “Quasi-Real-Time Snow Depth Monitoring System,” which collects snow depth data, and the numerical model known as SNOWPACK, which can calculate the snow water equivalent (SWE). The snow load per unit area is estimated to be equivalent to SWE. Based on the house damage risk level, snow load distribution was indicated by colors following the ISO 22324. The system can also calculate post-snow removal snow loads. The calculated snow load was validated by using the data collected through snow pillows. The simulated snow load had a root mean square error (RMSE) of 21.3%, which was relative to the observed snow load. With regard to residential areas during the snow accumulation period, the RMSE was 13.2%. YukioroSignal received more than 56,000 pageviews in the snowheavy 2018 period and 26,000 pageviews in the less snow-heavy 2019 period.

After the 2011 East Japan Earthquake, the Japanese Cabinet Office has promoted local governments and communities to develop a “Community Disaster Management Plan.” Local governments started to hold workshops to develop the said plan for residents in local communities. However, only a few residents (i.e., those who are interested in disaster prevention) participate in these workshops; thus, most residents do not have opportunities to survey disaster prevention. Considering this issue, we decided to develop a supporting application for individual disaster management plans by analyzing hazard risks and land features. In this research, we focused on evacuation planning for residents. Furthermore, we developed it as web-based application as any resident connected to the internet may be struggling with their evacuation. In our proposed application, users have to take seven steps: (1) learn features of tsunami attack and countermeasures during a tsunami disaster, (2) set start point for evacuation, (3) set first and second goal for evacuation based on lessons learned from the “Miracle of Kamaishi,” (4) search the shortest evacuation route from start point through the first goal to the second goal, (5) review change of elevation on the evacuation route, (6) review hazard risks and land feature on the evacuation route and to reroute if necessary, and (7) download their settled evacuation route to their own devices as a GPX file. After developing a prototype of the application, we published it as a web service. While the publishing was in process, we gathered logs on how users took actions based on our proposed application. Approximately 10 days after publishing the prototype, we analyzed the path of users’ action flow, and we detected issues that need to be resolved to improve esidents’ disaster management capacity during tsunami disasters. Generally, our application helped prepared users for tsunami disaster prevention.

This paper attempts to activate a large scale shopping district (shotengai) using new internet techniques. Recently decline of shotengai is a serious problem by development of large shopping centers. We made a new approach with internet techniques to activate shotengai, which is a typical Japanese shopping district. The Osu Shotengai is one of the most famous shotengai in Nagoya, Japan, which includes about 400 stores. We developed Osu shotengai official web site, called “At Osu.” First, the information of 400 stores in Osu shotengai, which includes 9 streets, was collected. Then we created an interactive “Information Visualization System” to put fresh information of shotengai on the web site in real time. It includes “Comment Upload System, ” where store owners can upload their comments and informing news directly on the web site. Further, we developed a new approach to stimulate store owners motivations for participating in the web site. And we also mention about an attractive and interactive web design using twitters to get opinions of users. By developing the new web site, the number of visitors of “At Osu” has increased rapidly. Many articles about this new approach to activate shotengai with a web site were published in newspapers or magazines and we have receives many inquiries.
