The worldwide use of cell phones has rapidly increased over the past decades. With the increasing use of mobile phones, concern has been raised about the possible carcinogenic effects as a result of exposure to radiofrequency electromagnetic fields. The objective of this study was to explore the perceptions and opinions towards brain cancer related to cell phone use among university students in Malaysia. The study revealed that the majority of the study participants believe that there is no relationship between brain cancer and hand phone use.DOI: http://dx.doi.org/10.3126/ajms.v4i1.7808 Asian Journal of Medical Sciences 4(2013) 1-4

The possibility that using a cell phone could cause brain cancer first arose in the early 1990s and has been the subject of research since then. Radiofrequency waves used in cellular communications are far too weak to induce cancer by any known mechanism, and most scientific and regulatory bodies have found the evidence for health effects from use of mobile phones to be unconvincing. Nevertheless, positive results, largely from a single group of researchers, and an ambiguous assessment from single agency have kept the controversy alive. New studies are in progress.

The use of mobile phones has become increasingly popular in recent years and it is more prevalent among university students. The widespread usage of cell phones has attracted the attention of many students, thereby increasing their rate of cell phone dependency. This study aimed to describe cell phone behaviours among undergraduate regular students at the University of Cape Coast. A survey research design was adopted for the study. Through the use of the stratified sampling technique, a sample of 2,061 undergraduate regular students participated in the study. Questionnaire adapted from Choliz’s (2012) Test of Mobile-phone Dependence (TMD) was used. The internal consistency, estimated using McDonald’s omega coefficient, ranged from .84 to .95. Means and standard deviations were used in analyzing the data for the study. The findings of the study revealed that students were prevalent in the use of cell phones in sending text messages, followed by surfing of the internet, length of time spent on the cell phone, and use of cell phone as a source of entertainment. It was recommended among other things that students should consciously regulate their use of cell phones so that it does not jeopardize their academic work.

Cell phones are now widespread in many countries including Japan where we teach, and are particularly popular among university students. Although they can be a distraction in the classroom, functions such as Internet access and e-mail capability have transformed them into sophisticated communication tools. But are they also potentially useful in language learning? While task-based approaches (Nunan, 1989) adapted to desktop e-mail are now a growing area of research in CALL (Greenfield, 2003; Gonzalez-Lloret, 2003), cell phones have yet to receive much attention. This paper reports on a classroom research project aimed at evaluating the use of mobile phones as tools for classroom learning. Freshman university students in intact EFL classes (2 elementary classes, 2 lower intermediate) were first surveyed regarding their cell phone use and pre-tested to assess their knowledge of certain target learning structures. Following this they were subdivided into three groups: (a) using cell phone text messages, (b) using computer e-mail, and (c) speaking. The learners were paired, trained with warm-up tasks, and given two further sets of tasks to complete (one in class and the other at home). The target vocabulary appeared in the initial narrative task. All messages sent while doing the tasks were saved for analysis. The speaking task pairs were recorded and samples were transcribed for comparison. Finally learners took a post-test the following week to assess short-term learning gains. This project drew attention to a number of potential advantages of mobile phones as well as highlighting some limitations, but overall suggested that mobile phones represent a language learning resource worthy of further investigation.

ABSTRACT Background: The use of technological devices is growing rapidly, and the use of cell phones increases in parallel. Dependence on technological devices is a particular factor in this increased exposure. Many studies have been performed on this electromagnetic field, but no definite conclusions have been drawn. Objective: The purpose of this research was to investigate exposure to electromagnetic field, cell phone use behaviors, the specific absorption rate (SAR) values, and changes in health occurring after exposure in university students. Methods: A questionnaire was administered to 1,019 volunteer students aged 18–24 years at the Niğde Ömer Halisdemir and Recep Tayip Erdoğan Universities in 2018–2019. The questions were based on a survey of the literature. Results: The students spent an average 4–8 hours per day on their cell phones, and findings such as headache (p=0.002), concentration deficit (p=0.001), tiredness on waking in the morning (p=0.001), hyperactivity (p=0.001), general feeling of fatigue (p=0.001), and lethargy (p=0.001) increased in a statistically significant manner with length of use. Conclusions: Participants exhibited high levels of cell phone use and experienced biological, behavioral, and sleep problems. They also had very little knowledge about specific SAR values, an important criterion concerning cell phones.

Smartphone Use

The use of cell phones has increased worldwide in the past few decades, particularly in children and adolescents. Using these devices provides personal benefits. Communicating through cell phones was a very important factor in the socioeconomic progress of developed countries. However, it is beyond doubt that its indiscriminate use can accompany certain psychiatric disorders or cause some disorder in a person, within the phobic group of anxiety disorders called nomophobia—associated with anxiety, nervousness, discomfort, and distress when contact with the smartphone is lost, mainly in young users. This research proposal aims to identify symptoms that have not yet been detected by intensive cell phone use, considering that in Peru there are few studies of human health engineering and the physical mental health. Is for this reason that in our study, we sought to identify the symptomatic factors of nomophobia presented by students at the National University of Engineering and its interference with their academic life. To accomplish this study, we designed a questionnaire according to our reality with the use of focus groups techniques when the test was taken in class. Three symptomatic factors of nomophobia were identified: feelings of anxiety, compulsive smartphone use, and feelings of anxiety and panic. The study included a representative sample of 461 students of different years of study engineering (21\% women, 79\% men, over 17 years of age). Finally, given the widespread adoption of smartphones and their integration into educational environments, the results of this study can help educators understand students’ inclination to use their smartphones at all times.

The use of cell phones has increased worldwide in the past few decades, particularly in children and adolescents. Using these electronic devices provides personal benefits. Communicating through cell phones was a very important factor in the socioeconomic progress of developed countries. However, it is beyond doubt that its indiscriminate use can bring up certain psychiatric disorders or cause some disorder in a person, within the phobic group of anxiety disorders called nomophobia; basically associated with anxiety, nervousness, discomfort, and distress when contact with the smartphone is lost, mainly in the youngest users. This research proposal aims to identify symptoms that have not yet been detected by unceasing cell phone use, considering that in Peru there are few studies of human health engineering and the physical mental health. For that reason, we sought to identify the symptomatic factors of nomophobia presented by students at the National University of Engineering and its interference with their academic life. To accomplish this study, we designed a questionnaire according to our reality with the use of focus groups techniques when the test was taken in class.

The Impact

BACKGROUND Cell phone use brought convenience to people, but using phones for a long period of time or in the wrong way and with a wrong posture might cause damage to the human body. OBJECTIVE To assess the impact of improper cell phone use on transport and chronic injuries. METHODS Studies were systematically searched in PubMed, EMBASE, Cochrane, and Web of Science up to April 4, 2019 and relevant reviews were searched to identify additional studies. A random-effects model was used to estimate the overall pooled estimates. RESULTS Cell phone users were at a higher risk for transport injuries (RR: 1.37, 95%CI: 1.221.55), long-term use of cell phones increased the transport injury risk to non-use or short-term use (RR: 2.10, 95% CI: 1.632.70). Neoplasm risk caused by cell phone use was 1.07 times that of non-use (95% CI: 1.011.14); Compared with non-use, cell phone use had a higher risk of eye disease, with a risk of 2.03 (95% CI: 1.273.23), the risk of mental disease was 1.26 (95% CI: 1.171.35), the risk of neurological disorder was 1.16 (95% CI: 1.021.32), and a pooled risk of other chronic injuries was 1.20 (95% CI: 0.981.59). CONCLUSIONS Cell phone use at inappropriate situations has a negative impact on the human body. Therefore, it is necessary to use cell phones correctly and reasonably.

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.
