Concentration problems, when present to an excessive degree, are also characteristic of certain physical and psychological conditions. Rare condition that affect the brain and some emotional problem as well as conflicts can also influence a student’s cognitive functions and thus impair concentration. The factors that influence the university students on low concentration in class are fatigue, cellphone, personal circumstances, and lack of motivation. BODY PARAGRAPH Firstly, the factor that affects students’ concentration is fatigue. Fatigue is a common, almost universal feature of modern life (Dawson, Noy, McKnight, & Nolan, 2013).

In 1973, the first cell phone call was made with a prototype, 10 years later, the first cellphones were released. Up to that time everyone had a landline and as the years went on, we had 1G, 2G, 3G and now, 4G, and 5G is being talked about in the not so distance future. As good as the technology was, there was still a problem that plagued all of this wonderful technology and that was the means by which the technology operated, “the battery”. The first cellphone battery only lasted 20 minutes and took 24 hours to recharge. However, at that time, it was not a problem because the phone weighed 1.1kg (2.42 lbs.), you were not able to hold the phone up to your ear for much longer than 20 minutes. The battery has not been able to keep up with the speed and function of the cellphone. However, that may soon change, people are working constantly to bring a fix for the battery so we can truly bring the cellphone into the 21st century. Just think of the possibilities!

Annexes * Survey sample | | Abstract: This study examined the usage and implications of social networking sites (SNS) among college students. A survey was administered to a non-random sample of 143 college students on SNS use, perceptions of SNS communications, and awareness of the impacts of SNS in academic performance. Data were collected from a non-random sample of students attending different universities during the fall semester of 2014. Results revealed that female college students spent more time on SNSs than male students. According to results obtained, the higher number of respondents belonged to junior class rank students. As for SNS usage per typical day and respective age, no significant differences were found, concluding that there’s no relationship among these two variables. Significant correlations were found between age and gender, and the influence of SNS on users. Results also revealed that there were significant relationships between users’ usage per day and area of study, and the influence of SNS. A comparison between age and perceived impact of SNS to academic performance showed that there is no significant difference. The relationship between SNS usage rate per typical day and dependency on the cellphone was not significant...

The use of social networking sites has been widespread that they have not only caught the attention of academic and industry researchers worldwide but also us, in particular. Social networking sites are now being investigated by numerous social science researchers and an increasing number of academic commentators are becoming more and more interested in studying facebook, twitter, and other social networking services because of their probable impact on the society. While the social networking sites have the same key aspects, the cultures and responses around them that become apparent are varied. Most sites help strangers connect with others based on shares personal interest, political and economic views, or simple recreational activities.

Cellular Effects

...and actual conversation skills are diminishing. Exposure to electromagnetic radiation emitted from cellular devices has become a concern and is being studied from many various angles to determine actual health risks from cell phone use. Whether it is for personal or business use, the cell phone has become a permanent fixture in our lives, could have potential health risks, and can become an addiction if necessary steps are not taken to control use and dependency.   Cellular Technology and Society Today At any store they are visible. They have their hand plastered to their ear or they are seemingly talking to no one. These are the cellphone users. Hayley Tsukayama, a writer for the Washington post asserts that according to the Pew Internet and Life Project only seventeen percent of Americans still have a land line and ninety percent own a cellphone. (Tsukayama, 2014) The largest contributor to this trend is convenience. Most cellular devices are small and easily portable, allowing the user to move around freely. The ability to be in contact on the road, at work, or out having fun has pushed the trend that the American consumer is converting to cellular devices. Adding to this trend is the ability of cellular devices to do more than just make a call. “Cell phones are not just about calling or texting – with expanding functionality, phones have become multimedia recording devices and pocket-sized...

Wireless Network for Rural

...A Low-Cost Efficient Wireless Architecture for Rural Network Connectivity 1 Introduction Many rural regions around the world, especially in developing regions, do not have good connectivity solutions which are economically viable. As a result, many of these regions remain disconnected from both the rest of the world and from progress in general. In this proposal, I will describe the design of WiFi-based Rural Extensions (WiRE), a new wireless network architecture that can provide connectivity to rural regions at extremely low costs. The WiRE architecture is tailored for the typical rural landscape in several developing regions, in which the population is spread across small but scattered rural regions (less than 1-2 sq kms) within 100-200 kms of the city. WiRE is designed to be a wireless distribution network that extends connectivity from the city to each village. The WiRE architecture has largely been inspired by my prior work on WiFi-based Long Distance (WiLD) Networks [42, 62, 35, 54, 64, 34], a low cost point-to-point network connectivity solution that provides very high bandwidth (typically 6− 10 Mbps) over very long-distances. While prior work on WiLD networks [48, 5, 42, 62, 35] has made significant progress in the design of highperformance MAC layer solutions, we still lack a vision of how to design a comprehensive, low-cost, rural connectivity architecture that can efficiently support a wide-range of applications. It is this goal that I wish to achieve...
