Mobile Phone Usage

Ever since the discovery of the Mandelbrot set, the use of computers to visualise fractal images have been an essential component. We are looking at the dawn of a new age, the age of ubiquitous computing. With many countries having near 100% mobile phone usage, there is clearly a potentially huge computation resource becoming available. In the past years there have been a few applications developed to generate fractal images on mobile phones. This chapter discusses three possible methodologies whereby such images can be visualised on mobile devices. These methods include: the generation of an image on a phone, the use of a server to generate the image and finally the use of a network of phones to distribute the processing task.

Mobile Phone Usage

As mobile devices increasingly become a ubiquitous and essential part of everyday life, marketers must face a host of new challenges. This new marketing environment requires that marketers understand how consumers use their mobile phones and, more particularly, how they perceive and derive value from doing so. In this article, the authors suggest that mobile services offer either context-related or content-related values. They also explore managerial implications, by revealing factors that influence consumers to utilize mobile phone services.

The topic of the use of mobile devices and headphones on pedestrian crossings is much less explored in comparison to the use of the mobile phone while driving. Recent years have seen many discussions on this issue, especially in foreign countries. The Slovak Republic, however, has not been giving it enough attention (and it is not mentioned in the National Road Safety Plan for the Slovak Republic from 2011 to 2020). This paper aims to draw attention to this issue. It presents basic outputs of a pilot study on pedestrian safety, with a focus on the use of mobile devices and headphones at selected non-signalized pedestrian crossings in three Slovak cities. Overall, 9% of pedestrians used headphones or mobile devices at observed pedestrian crossings (4% of them used headphones, 1% used headphones and at same time used their mobile phone, 2% made phone calls and 2% used their mobile phones). While these numbers can be considered relatively low, the study proved that during weekdays every 2 min someone was using the crossing without fully focusing on crossing the road safely. Another main finding was that although the safety risk at pedestrian crossings is increased by factors such as rush hour traffic or reduced visibility, pedestrian behavior related to the use of mobile phones and headphones does not change. A safety assessment was also carried out at the crossings. The results show that pedestrian behavior is not affected by the level of safety of the crossing (e.g., visibility of the crossing for drivers). The results of the presented analysis suggest that action is needed to change that. Due to the lack of information about accidents involving pedestrians using mobile phones and headsets when crossing the road, no relevant statistical data could be analyzed. The dataset collected can be used as a basis for further investigation or comparisons with other countries of the relevant indicators. In future work, we would like to include a pedestrian–driver interaction factor focusing on driver speed behavior in relation to pedestrians (who are on or are about to step onto a pedestrian crossing) and identify critical situations caused by improper behavior of drivers and/or pedestrians. This will help to understand speed adjustment problems related to pedestrian crossings.

Insight Into

As the world becomes increasingly interconnected, mobile phones has become the utmost preference device for most Malaysian to stay connected. Over the past decades, mobile phone users in this country has been increasing steadily. Percentage of individuals in Malaysia using mobile phones increased from 94.2% in 2013 to 97.5% in 2015 (DOS, 2016). According to the hand phone users survey carried out by MCMC (2017) , there were 42.3 million mobile phone subscriptions with a penetration rate of 131.2% to a population of 32.3 million at the end of 2017. In a study on university students of Malaysia, Ho et al. (2018) revealed that a substantial amount of them (18.83%) actually do not know what to do with the waste mobile phones. This reflects the low awareness amongst university students and the lack of formal management system in Malaysia. Moreover, the findings show the rate of replacements of even functioning phones is high and a significant high stockpile of the waste mobile phones, which in turn increase the generation of e-waste eventually. Tremendous amount of waste mobile phones are expected to be generated in Malaysia. Malaysia is now facing a challenge on how to deal with the ever growing generation of waste mobile phones from users. An insight into their e-waste management practices and key predictors in relation to waste mobile phones recycling intention are therefore essential. This would help to lay the foundation for developing a suitable, workable, effective and efficient system of collecting e-wastes. This study aims to probe into university students' behavioural intentions to recycle waste mobile phones. In the meanwhile, it is expected to derive the policy implications for the future expansion and enhancement of mobile phones recycling response rate.

BACKGROUND No study has comprehensively investigated the association between the usage of typical screen-based electronic media devices and sleep quality in a Chinese population with individuals in a wide range of ages. OBJECTIVE This study aimed to understand the characteristics of television (TV) viewing, computer usage, and mobile phone usage in a representative Chinese population in Macau and to examine their roles in predicting the variations in sleep quality. METHODS This cross-sectional study was an analysis of 1500 Macau residents aged 15 to 90 years based on a community-based health needs assessment study entitled, “Healthy Living, Longer Lives.” Data collection was conducted in 7 districts of Macau from 2017 to 2018 through face-to-face interviews. The durations of daily TV viewing, computer usage, and mobile phone usage were recorded in a self-administered questionnaire. The Chinese version of the Pittsburgh Sleep Quality Index (PSQI) was used to assess the sleep quality. RESULTS The prevalence of TV, computer, and mobile phone usage was 78.4% (1176/1500), 51.6% (769/1490), and 85.5% (1276/1492), respectively. The average daily hours of usage were 1.75 (1.62), 1.53 (2.26), and 2.85 (2.47) hours, respectively. Females spent more time watching TV (<i>P</i>=.03) and using mobile phones (<i>P</i>=.02) and less time on the computer (<i>P</i>=.04) as compared to males. Older adults were more likely to watch TV while young people spent more time using the computer and mobile phones (<i>P</i> for all trends&lt;.001). The mean PSQI global score was 4.79 (2.80) among the participants. Females exhibited significantly higher PSQI scores than males (5.04 vs 4.49, respectively; <i>P</i>&lt;.001). No linear association was observed between the PSQI score and the amount of time spent on the 3 electronic devices (<i>P</i>=.58 for PSQI-TV, <i>P</i>=.05 for PSQI-computer, and <i>P</i>=.52 for PSQI-mobile phone). Curve estimation showed significant quadratic curvilinear associations in PSQI-TV (<i>P</i>=.003) and PSQI-computer (<i>P</i>&lt;.001) among all the participants and in PSQI-mobile phone among youths (age, 15-24 years; <i>P</i>=.04). After adjustment of the gender, age, body mass index, demographics, and lifestyle factors, more than 3 hours of TV viewing and 4 hours of computer usage or mobile phone usage was associated with 85% (95% CI 1.04-1.87; <i>P</i>=.008), 72% (95% CI 1.01-2.92; <i>P</i>=.045), and 53% (95% CI 1.06-2.22; <i>P</i>=.03) greater odds of having poor sleep quality (PSQI score&gt;5), respectively. CONCLUSIONS The mobile phone was the most popular screen-based electronic device used in the Macau population, especially among young people. “J” shape associations were observed between sleep quality and the duration of TV viewing, computer usage, and mobile phone usage, indicating that the extreme use of screen-based electronic devices predicted poorer sleep status, whereas moderate use would be acceptable.

In developing countries like the Saudi Arabia, due to high mobile phone penetration rates, any electronic government initiatives that don’t take mobile technology into account will eventually fail. While the number of landline phones and internet subscribers are growing steadily over the past few years, the number of mobile phone users and its penetration rates are skyrocketing. In the near future and with the many mobile phone features, mobile phones will remain the main media of communication and a main source for providing information to citizens and customers.

And Performance

In the past few years, the mobile phone’s performance has increased rapidly. According to IDC’s Worldwide Mobile Phone 2004-2008 Forecast and Analysis, sales of 2.5G mobile phones will drive market growth for the next several years, with sales of 3G mobile phones finally surpassing the 100 million annual unit mark in 2007. Future mobile phones can support more than 20,000 colors. With the advancements in functionality and performance of mobile phones, users will use them for all sorts of activities, and that will increase mobile content service requests. Currently, the pricing of mobile content service is up to each provider; typically they implement a fixed price called a market price because the providers do not have a formula to estimate the price according to the actual cost of their services. This article proposes a dynamic pricing model based on net cost for mobile content services.

In this article, we explore the day-to-day importance of digital media, specifically the use of mobile phones in the lives of migrant minors—also known as unaccompanied foreign minors—in juvenile residential centres. For this study, we employed a general ethnographic methodology and, in particular, a workshop based on different artistic techniques that encouraged the young people involved to become active participants, committed from the start in the generation of the material to be used for the analysis of their daily practices. This approach emerged from the recognition of the importance for these young people to feel included and connected. Migrant adolescents take refuge in their mobile devices to participate in the youth microculture, both locally and globally. In addition, they are able to access different social networks that allow them to play out the personas they wish to adopt. Finally, we recognise the importance of digital media in allowing them to maintain close and affective relationships with their relatives, fellow citizens, and communities in their country of origin.

Hygiene Compliance

Background: The introduction of new technologies into the medical field has the duality of improvement and concerns about correct usage and cleaning. Mobile phones are used by healthcare professionals (HCPs) in the work place, and there is not an official policy about their use in health environment. Methods: We asked 60 intensive care unit (ICU) HCPs from 2 units (the burn unit and the internal medicine unit) to participate in an electronic survey about mobile phone usage and hand hygiene compliance; we also cultured the hands and mobile phones of the participants. Unfortunately, 13 HCPs did not participate. Susceptibility testing of the strains was conducted, as well as molecular testing. Results: Overall, 47 HCPs responded to the inquiry: 19% were nurses (9 of 47), 19% were resident physicians (9 of 47), 17% were nursery technicians (8 of 47), 17% were physiotherapists (8 of 47), 13% were cleaning staff (6 of 47), 11% were consultants (5 of 47), and 4% were technicians (2 of 47). Moreover, 26 of 47 participants (55%) were woman and 21 (45%) were men. From all HCP categories, 39 of 47 respondents (83%) reported that they had optimal hand hygiene compliance. However, 92% of respondents had a colonized hand and 90% had a colonized mobile phone. Also, 44 of 47 HCPs (94%) reported that the took their personal mobile phone into the workplace; 40 (85%) reported that they used it during the work day and 35 (74%) reported that they cleaned it. However, 8 HCPs (26%) reported that they had never cleaned the device. All of the HCPs understood that mobile phones can harbor bacteria, and 27 of 47 HCPs (57.45%) indicated that they use 70% alcohol to clean their mobile phones. In contrast, the first choice for hand hygiene was water and soap in 51% of HCPs (24 of 47). Also, 3 HCPs did not have any colonization in the hand culture but had healthcare-associated infection (HAI) pathogens in the mobile phone culture. Conclusions: A policy regarding mobile phone usage in the healthcare setting should be in place, and cleaning of electronic devices in hospitals should be standardized.Funding: NoneDisclosures: NoneFunding: NoneDisclosures: None

The study aims at investigating Saudi college students' perceptions and attitudes towards the effectiveness of using mobile devices for academic purposes and other related activities. It tries to determine digital devices mostly used by students and measures to what extent they exploit these devices for academic purposes and in their other frequent activities. A survey was given to thirty-four Saudi university EFL students studying at the department of English and Translation, University of Jeddah, Saudi Arabia. The overall results have shown that most students always hold their mobile phones and bring them inside the classroom. Additionally, most of students have showed preference for using mobile devices for academic purposes and other related activities. The benefits of this study could be utilized for encouraging students to benefit from their mobile devices academically and designing future learning activities as well as mobile phone usage in the EFL classroom.
