The purpose of this study was to analyze and determine how much influence the use of cellphones on student learning outcomes in grade IV SD Negeri 060833 Medan Petisah District. This research is a quantitative research which is included in the ex-post facto research. The population taken was the fourth grade students with a total of 22 students, of which 8 male students and 14 female students at SD Negeri 060833 Medan Petisah sub-district, with a total sample size of the total population. Data analysis used the One Kolmogrov-Smirnov data normality test and hypothesis testing with Simple Regression (Simple Regression). Based on the results of hypothesis testing using simple regression analysis, the effect of the use of mobile phones on student learning outcomes, the value of tcount = 2.701 ≥ (t table) = 2.079 with a significance of 0.491> 0.05, it can be concluded that there is an "Effect of Mobile Use on Student Learning Outcomes in SD Negeri 060833 Medan Petisah sub-district with a large contribution of 2.4%.

RICE FARMER'S USING MOBILE IN MARKETING OPERATIONS: AN ANALYTICAL STUDY IN THE SPECIFIC REGION OF BANGLADESH

Rice is a major staple crop in Bangladesh, and its production has a profound effect on the country's agricultural sector. Large distribution networks in Bangladesh may drive up rice prices. The scarcity of marketing information prevents farmers from making decisions when planning their output and sales. This study aimed to analyze the variables that influence mobile usage and the effects of mobile use in rice marketing. 100 farmers were selected by two steps sampling procedure from the rural area of Upazilla, Bangladesh. 100 farmers in all, mostly small-scale rice farmers with an average plot size of 1.88 acres, were approached using a concise interview format & questionnaires. The data was evaluated using a variety of statistical methods, including correlation and regression analysis using a binary logistic regression model. The analysis was carried out utilizing the SPSS. Studies showed that 75% of mobile phone owners utilize it for paddy marketing. Income and education have a significant influence on cellphone usage, as shown in regression analysis. In the Likert scale study, there was a highly positive impact on having access to a broad variety of information, the accuracy of that information, negotiating power, and reducing market intermediaries' and transportation corporations' oppressiveness. Most farmers can save time and money by acquiring information themselves. It can be concluded that the adoption of mobile phones facilitates marketing activities and all potential consequences for rice farmers. Assuring mobile phone utilization could be essential in this area to improve the calibre of rice marketing.

A cross-sectional analysis to study the effects of mobile use on brainstem auditory response in young healthy male adults

Background: The intensive use of mobile phones has given rise to adverse effects concerning the potential influences of electromagnetic fields on human health. The ear, being the closest, is the direct recipient of electromagnetic radiation, thus making it the most likely affected organ. The present study assessed the effects of mobile usage on brainstem auditory responses in young healthy male adults using brainstem-evoked response audiometry. Aims and Objectives: The present study aimed to evaluate the effects of long-term repeated exposure to mobile phones on the hearing of young healthy male adults by assessing and comparing absolute wave latencies and interpeak latencies (IPLs) of brainstem auditory responses. Materials and Methods: The cross-sectional study was conducted using the RMS EMG SALUS 2C machine in the Physiology Department of SMS Medical College, Jaipur. This was an analytical type of observational study design incorporating a total of 70 young healthy male adults from SMS Medical College, Jaipur, in which Group I was using mobile for >2 h/day for the duration of >1 year and <5 years and Group II was using mobile for >2 h/day for the duration of more than 5 years. Results: The IPL I–III and I–V of the right ear of Group II was significantly prolonged (P < 0.05) compared to IPL I–III and I–V of the right ear of Group I. Conclusion: This study revealed a significant prolongation of IPLs in the right ear of Group II mobile users associated with duration of usage.

Smart Phones, Bad Calls? The Impact of In-Store Mobile Technology Use on Purchase Behavior

This research investigates the impact of consumer-owned mobile device use on decision-making. We build on the limited prior research on mobile technology in consumer research by considering the differing ways consumers utilize mobile devices at the point of decision. In particular, we conceptualize and examine two major categories of mobile device use: task-unrelated and task-related use. This demarcation is based upon the relationship between the mobile device usage and the decision situation. Using data from both field and experimental settings, we demonstrate that depending on use, mobile devices can act as a double-edged sword with either positive or negative implications for consumers. From a substantive perspective, this work is important because mobile technologies are a fast-growing communications medium and consumers are becoming increasingly reliant on these technologies in their daily lives. From a theoretical perspective, understanding the negative role that mobile technologies play in shaping consumer decision-making extends the research on distraction beyond the context of driving. In particular, we demonstrate the general deleterious effect of mobile use on decision-making even for routine decisions. Furthermore, we identify positive effects on decision-making by highlighting mobile device’s utility as a decision aid.

Effects of mobile telephone tasks on driving performance: a driving simulator study

Mobile phone use while driving is increasing among road users. Although the most of countries made illegal the cell phone use while driving, the drivers still use it both for calling and texting. Several studies investigated the distraction factors related to the use of mobile while driving and the effects on road safety. The main findings of these studies generally demonstrated an increasing of reaction time and decreasing of driving performance especially during not critical driving conditions, while the evaluation of the effects of mobile use during critical driving conditions is not so much investigates. The overall objective of this work is to contribute to the evaluation of the effects of the mobile phone use on driving safety. Specifically the effects of using cellular phone at the same time the driver is faced with making a critical stopping decision are investigated. The experiments are carried out using an interactive driving simulator. Three different road scenarios (urban road, rural road and motorway) are simulated. Thirty subjects take part to the experiments and drive four times each scenario: one time without calling (control scenario) and the other three times answering the calls by hand-held mobile, hands-free mobile and hands-free voice device. The driver's reaction time, the deceleration rate, the speed and the following distance are evaluated. The main effects of driving and calling are observed in the urban scenario, where the decreasing of driving performance is much more evident than in the rural and motorway scenario. Not significant differences on driving performances are found across the three telephone modes.
