Electronic cigarette (e-cigarette) use has become increasingly widespread throughout the world, including in Japan. However, little is known about how e-cigarettes are used in Japan, a country with heavy restrictions on nicotine-containing e-liquids and/or vaping products. This study examined e-cigarette use (e-cigarette use duration, frequency of use, device type, electrical resistance, nicotine use, favorite e-liquid flavors) among users in Japan, through an online survey using a web-based self-reported questionnaire which included questions about sex, age, combustible cigarette and heated tobacco product (HTP) use behaviors. Of 4689 e-cigarettes users analyzed, 93.5% were men and 52.9% had been using e-cigarettes for 1–3 years. Over 80% used e-cigarettes every day; 62.3% used nicotine liquid, and half of the nicotine liquid users used nicotine salt. The most popular liquid flavor was fruit (prevalence: 68.1%), followed by tobacco (prevalence: 48.4%). While 50.9% were e-cigarette single users, 35.2% were dual users (e-cigarettes and cigarettes or HTPs) and 13.8% were triple user (e-cigarettes, cigarettes and HTPs). This is the first comprehensive survey of Japanese e-cigarette users and our finding suggest more than half use nicotine liquid, although e-cigarettes containing nicotine liquid have been prohibited by the Pharmaceutical Affairs Act since 2010 in Japan. The study also showed 49.1% of participants used cigarettes and/or HTPs concurrently (dual or triple users).

<p>Research on how to counter phishing from a user behavior perspective has been explored for over a decade, yet the prevalence of such threats is increasing. This thesis aims to provide a modern perspective by considering if there is a difference in how susceptible an individual is on a mobile device versus a desktop email client. Currently very few studies consider phishing on mobile devices and the research is unclear as to the potential difference in susceptibility rates between the two device types. Initially a review of 60 phishing emails received by the university that had passed mail filtering were used to assist in the design of the messages to be used in the second stage of the study. Following this a simulated phishing attack on two groups in one unit of professional administrative staff in the university (141 in total with 71 in Group A and 70 in Group B) within the university was undertaken. The defining characteristic between the groups was how they responded to a message with a ‘loss versus gain’ appeal. This area has received limited exploration in the research and findings remain unclear. This study found that people were statistically far more susceptible to the ‘gain’ message of a free coffee at 28.2% than the ‘loss’ message of Office365 account suspension 7.1% . For device type there appears to be no statistically significant difference, even between the groups. This study highlights the complexities of device usage around phishing, that have not been clearly highlighted in previous studies, such as people viewing emails with one device and falling victim on another device.</p>

Abstract Purpose To examine the effect of assistive devices on the precision of digital impression for multiple implants placed in the edentulous maxilla. Methods A reference model representing an edentulous maxilla with four implants was developed. The digital impression group included three settings: Type 0, without an assistive device; Type 1, with an assistive device connecting only neighboring implants; and Type 2, with an assistive device connecting not only neighboring implants but also the two posterior implants, with perpendicular branches from this bar towards the anterior implants. Digital impressions were made five times for each type using three intraoral scanners (IOSs). For conventional method, silicone impressions and verification jigs were prepared; fabricated plaster models were scanned using a laboratory scanner/industrial 3D scanner. In analysis 1, two-way ANOVA analyzed the effect of IOSs and assistive devices on the precision of digital impressions. In analysis 2, one-way ANOVA compared the silicone impressions, the verification jigs, and the most precise group of digital impressions from analysis 1. Results In analysis 1, the IOS and assistive device type (F = 25.22, p < .0001) effects and the interaction between these two factors (F = 5.64, p = .0005) were statistically significant. In analysis 2, CON, VJ, and digital impression with Type 2 devices (most precise devices in analysis 1) were compared; better precision was obtained by digital impression with Type 2 device than by CON and VJ (F = 30.08, p < .0001). Conclusions For implants placed in an edentulous maxilla, digital impressions with assistive devices can provide better precision compared to silicone impressions and verification jigs.

BACKGROUND Electronic cigarette (e-cigarette) use has become increasingly widespread throughout the world, including Japan. However, little is known about how e-cigarettes are used in Japan, a country with heavy restrictions on nicotine-containing e-liquids, vaping products. OBJECTIVE This study comprehensively examined e-cigarette use, including e-cigarette use duration, frequency of use, device type, electrical resistance, nicotine use, favorite e-liquid flavors and concurrent use with cigarettes and/or HTPs in Japan. METHODS This study examined the detail of e-cigarette use (e-cigarette use duration, frequency of use, device type, electrical resistance, nicotine use, favorite e-liquid flavors) among users in Japan, through an online survey using a web-based self-reported questionnaire which included questions about sex, age, combustible cigarette and heated tobacco product (HTP) use behaviors. RESULTS Of 4,689 e-cigarettes users analyzed, 93.5% were men and 52.9% had been using e-cigarettes for 1-3 years. Over 80% used e-cigarettes every day; 62.4% used nicotine liquid, and half of the nicotine liquid users used nicotine salt.
