Smartphone usage rate has been increased, and so has on the streets while walking. Concerns for traffic accidents associated with the use have been growing, but there has been limited information regarding smartphone usage pattern while walking. A survey was conducted to explore the usage pattern in terms of frequency of use while walking, and history of accidents, and apps used while walking. Of 441 students, 95.9% used smartphones ‘sometimes’ or more often while walking. 91.8% and 54.6% of 423 used their phones while waiting for a signal and while crossing the crosswalk, respectively. 57.9% experienced accidents or near misses when using smartphones while walking. Text messaging (87.7%) was the most frequently used app while walking, followed by music and phone calls. The findings indicate that using smartphones while walking is a common behavior of young users, and suggest habitual users on the streets were in greater risks for accidents.

Media Enjoyment

Building upon online communication attitude research, this article explains why people use certain media in their social relationships by offering an initial formulation and test of media enjoyment theory (MET). We investigated whether medium enjoyment mediated the effects of social influence and communication competence on media use. We proposed that perceived miscommunication would moderate the mediating effect of medium enjoyment. Results were consistent with MET across voice phone calls, email, text messaging, and Facebook. The results indicate an indirect effect of social influence and communication competence on media use through the mediator of medium enjoyment. The pattern of mediation was strongest when participants held low levels of perceived miscommunication. These results suggest that people are most likely to use media when they perceive high levels of enjoyment from medium and low levels of perceived miscommunication. Theoretical implications highlight how MET can be developed in multimodal and dyadic contexts.

Background: Several studies have examined the risk of cardiovascular disease (CVD) among larger racial and ethnic groups such as Hispanics and African-Americans in the United States, but limited information is available on smaller subgroups such as Armenians. According to the World Health Organization, Armenia ranks eighth in CVD rates among all countries however it is unclear if Armenian immigrants living in the US have the same high rates of disease. This study examined whether being of Armenian descent increased the risk of having a positive exercise treadmill test (ETT) among patients treated at a safety net hospital in Los Angeles County. Methods: Data on patients who received an ETT from 2008-2011 were used to conduct a retrospective analysis of the relationship between Armenian ethnicity and ETT result as a surrogate measure for CVD. A multivariate logistic regression analysis was used to estimate the odds ratios (OR) for having a positive ETT among Armenians relative to non-Armenians, adjusting for the following pre-specified covariates: gender, age, diabetes, hypertension, hyperlipidemia, smoking, family history of coronary artery disease (CAD), and patient history of CAD. Results: A total of 5,297 patients, ages 18 to 89, were included. Of these, 13% were Armenian and 46% were male, with an average age of 53 years. Armenians had higher odds of having a positive ETT than non-Armenians (Crude OR=1.30, p=0.037, CI:1.02,1.66). After adjusting for CV risk factors, Armenians were still significantly more likely to have a positive ETT than non-Armenians (OR=1.33, p=0.029, CI:1.03,1.71). CAD (OR 2.02, p<0.001, CI:1.38,2.96), and hyperlipidemia (OR=1.31, p=0.008, CI:1.07,1.60) were also significantly associated with a positive ETT. Conclusion: Armenians have a higher likelihood of having a positive ETT than non-Armenians. This relationship appears to be independent of traditional CV risk factors and suggests a role for cultural and/or genetic influences.

ABSTRACT:BACKGROUND & OBJECTIVE: To compare the results of surgically operated vs conservatively treated patients of cerebral contusions due to traumatic brain injury. METHODOLOGY: This comparative study was conducted from January 2012 to December 2014 at the department of Neurosurgery, PGMI Lahore General Hospital, Lahore. A total of 50 patients were included in this study of both gender (male and female) and in the age range of 15-65 years. In our study 20 patients were managed conservatively while other 30 patients were operated for cerebral contusions. The mode of injury in our study was road traffic accidents and history of falls. RESULTS: Out of 50 patients, there were 41 (82%) males and 09 (18%) female patients. Their age ranged from 15 - 65 years. In this study the overall mean age is 38.36 years. The maximum numbers of patients were in their third and fourth decades of life. In our study the duration of hospital stay in conservatively managed patients was longer as compared to surgically treated patients who were discharged earlier. Mortality rate in surgically managed patients having a GCS ranged between 09 to 12 was very low contrary to the conservatively managed group, similarly the rate of delayed contusion formation and edema was also low in surgically managed patients as compared to those who were managed conservatively. CONCLUSION: Surgically managed patients of cerebral contusions in traumatic brain injury has better outcome and decreased hospital stay as compared to conservatively managed patients.

Emoticons are usually associated with the digital age, but they have numerous precursors in both manuscript and print. This article examines the circulation of emotional icons in nineteenth-century typographical journals as a springboard to understanding the relationship between emotion, materiality, and anthropomorphism as well the pre-digital networks of the “typographical press system.” It draws on literature from textual and typographical analysis, including the history of punctuation. It also demonstrates the ubiquity of emoticons in contemporary society and culture outside the world of computers, text messaging, and chat rooms.

BACKGROUND: The mortality rate due to road traffic accidents (RTA) is significantly high in Saudi Arabia (SA) compared to other countries. The visual function which includes good visual acuity (VA) and binocular vision are very important factors that can contribute to the incidence of RTA. AIM: The aim of this study is to investigate the association between refractive errors (REs) and the RTA in SA. METHODS: A total of 354 participants (mean age 22.67 ± 3.22 years) were recruited randomly to participate in this study from the population of Qassim district. Data collected using the questionnaire included participants’ age, sex, and education level, ocular and medical history, driving history as well as history of RTA. Ocular health examination including VA, RE measurements, and binocular vision function vision was measured and analyzed. RESULTS: The results of this study show that 48.3% of drivers had some form of REs with 3.4% being visually impaired. 217 (61.3%) of participants have had an RTA, and 119 (54.9%) of them have had more than two accidents in the past two years. The findings show no significant association between the occurrence of RTA and uncorrected REs or binocular vision dysfunction. CONCLUSION: Our data showed significantly higher rate of RTA among Saudi drivers which is much higher than any country in the world. The current Saudi regulations for obtaining driving license need to be modified, with implementing a comprehensive eye examination prior to acquiring or renewing drivers’ licenses.

The 1960S

Without evidence for an organic framework, biological and biochemical processes observed during amelogenesis provided limited information on how extracellular matrix proteins control the development of the complex fibrous architecture of human enamel. Over a decade ago, amelogenin nanoribbons were first observed from recombinant proteins during in vitro mineralization experiments in our laboratory. In enamel from mice lacking the enzyme kallikrein 4 (KLK4), we later uncovered ribbon-like protein structures that matched the morphology, width, and thickness of the nanoribbons assembled by recombinant proteins. Interestingly, similar structures had already been described since the 1960s, when enamel sections from various mammals were demineralized and stained for transmission electron microscopy analysis. However, at that time, researchers were not aware of the ability of amelogenin to form nanoribbons and instead associated the filamentous nanostructures with possible imprints of mineral ribbons in the gel-like matrix of developing enamel. Further evidence for the significance of amelogenin nanoribbons for enamel development was stipulated when recent mineralization experiments succeeded in templating and orienting the growth of apatite ribbons along the protein nanoribbon framework. This article provides a brief historical review of the discovery of amelogenin nanoribbons in our laboratory in the context of reports by others on similar structures in the developing enamel matrix.

Cell phones provide multiple mediums for communication (e.g., voice, text, video) and have become the defining technology of the 21st century. Text messaging (SMS; texting) has become a popular and regular medium for communication among adolescents. When compared to other age groups, adolescents are the most frequent users of text messaging. Adolescents are motivated to use this technology because it allows them to maintain constant communication with their social network in a convenient and private manner. Given the popularity of this technology among adolescents, research has begun to focus on the frequency of use and concerns (e.g., cyberbullying) associated with text messaging. The motivations for the use of text messaging, the influence of text messaging on relationships, and the culture surrounding adolescent text messaging have also motivated researchers and developmental scholars.

The capstone senior design class in the Department of Mechanical and Aerospace Engineering at The University of Alabama in Huntsville (UAH) is taught as a distributed Integrated Product Team (IPT) experience. Engineering students are teamed with students of different disciplines within UAH and with students at universities in other states and Europe. Because of the distributed nature of these teams, the IPT students must use a variety of technologies to communicate. The authors of this chapter found that the students prefer familiar, informal, contemporary forms of communication, including Google Groups/Sites, Skype, instant messaging, e-mail, phone calls, and text messaging for team communication and project management, and reject more formalized forms of communication, even if advanced features are offered. Most importantly, the authors found that the effectiveness of all forms of technology based communication tools is greatly enhanced when the students have the opportunity to personally meet prior to the design semester.

Abstract To evaluate the value of apnoea + hypopnoea index versus self-reported sleepiness at the wheel in anticipating the risk of sleepiness-related accidents in patients referred for obstructive sleep apnoea. A cross-sectional analysis of the French national obstructive sleep apnoea registry. 58,815 subjects referred for a suspicion of obstructive sleep apnoea were investigated by specific items addressing sleepiness at the wheel and sleepiness-related accidents. Apnoea + hypopnoea index was evaluated with a respiratory polygraphy or full polysomnography. Subjects had a median age of 55.6 years [45.3; 64.6], 65% were men, with a median apnoea + hypopnoea index of 22 [8; 39] events/h. Median Epworth sleepiness scale score was 9 [6; 13], 35% of the patients reported sleepiness at the wheel (n = 20,310), 8% (n = 4,588) reported a near-miss accident and 2% (n = 1,313) reported a sleepiness-related accident. Patients reporting sleepiness at the wheel whatever their obstructive sleep apnoea status and severity exhibited a tenfold higher risk of sleepiness-related accidents. In multivariate analysis, other predictors for sleepiness-related accidents were: male gender, ESS, history of previous near-miss accidents, restless leg syndrome/periodic leg movements, complaints of memory dysfunction and nocturnal sweating. Sleep apnoea per se was not an independent contributor. Self-reported sleepiness at the wheel is a better predictor of sleepiness-related traffic accidents than apnoea + hypopnoea index.

Abstract Objectives Rigorous evidence is needed to support uptake of recommendations to include low glycemic index (GI) foods in daily meal planning as an effective dietary self-care strategy for people with type 2 diabetes (T2D). We evaluated the effectiveness of a 12-week web-based GI-targeted nutrition education intervention on dietary intakes and GI-related knowledge among adults with T2D. Methods Participants were randomized to a control group (n = 34) that received standard printed copies of Canada's Food Guide and Diabetes Canada's GI resources or an intervention group (n = 33) that received those same materials, plus an online platform with six self-directed learning modules and supplementary print material. Each module consisted of a customized video, links to reliable websites, chat rooms, and quizzes. Evidence-based GI concept information included GI values of foods and advice for low-GI shopping, recipes, and cooking tips by a Registered Dietitian. Preferred supports through email, text messaging, phone calls, or postal mail to reinforce participants’ learning were also provided. The primary outcome, average daily dietary GI intake, was assessed using 3-day food records. Additional measures including GI knowledge and self-efficacy, glycated hemoglobin A1c, lipids, systolic blood pressure, body mass index, waist circumference, and computer proficiency, were assessed at baseline and at three months post-intervention. Results Participants (N = 67) were 64% men; mean (standard deviation [SD]) age 69.5 (9.3) years, with mean diabetes duration of 19.0 (13.7) years, BMI 30.1 (5.7) kg/m2 and A1c 7.1 (1.2)% at baseline. Mean daily GI intake decreased in the intervention group by 2.79 (7.77) compared to a 0.76 (6.48) increase in the control group (adjusted mean difference [95% CI]; −3.77 [−6.95, −0.58]). Mean GI knowledge 2.14 [0.59, 3.69], understanding of GI concept 1.65 [0.85, 2.44] and self-efficacy for consuming low-GI foods 1.29 [0.51, 2.07] increased among the intervention group (P &lt; 0.01) compared with the control group. Conclusions Web-based GI-targeted education program improved the quality of carbohydrate consumption among adults with T2D and may have been mediated through increases in knowledge and self-efficacy. Web-based nutrition education may be an effective alternative in this population. Funding Sources Canadian Foundation for Dietetic Research.
