Opis:
Studies show that mobile phones are an important part of youth lifestyle and culture. In establishing this, it is important to know how youth themselves perceive the importance of mobile phones in their life. Our research was based on a sample of 6th and 9th graders from Slovenia (n = 820). The data was collected using a questionnaire. The study showed that the most common reason for using mobile phones is to communicate with other pupils and the reason for having a mobile phone is to be connected with others. Moreover, various feelings and fears connected to mobile phone use are experienced by pupils. The study also revealed some possible dangers of MPs use by pupils. Based on the results, it is necessary to raise pupils’ awareness of the safe, moderate and critical use of mobile phones in their everyday life.

Opis:
Introduction: Legislation systems of most countries prohibited using the handheld mobile phone while driving due to the fact that it disturbs concentration and causes hand involvement. Every phone owner is accustomed to the ringtone of his phone and almost involuntarily endeavors to pick it up or check who calls. This engages one’s psychomotor skills, which in our opinion contributes to the attenuation of reaction time needed for performing other crucial functions. Objectives: The aim of the study was: (1) to evaluate the infl uence of the sound of a ringing mobile phone on the complex reaction time (RT) score in healthy subjects (owners), and (2) to check if there are any differences in RT when a landline phone and mobile phone ring. Methods: To assess RT we used our system and protocol of examination, previously validated. The examination conditions were standardized. All tests were performed in the same room with the same light and general acoustic conditions. The test group consisted of 23 women and 24 men, aged 19–24 years. The examination comprised 4 sessions: Training Session (TS) during which the subjects were accustomed with the application and sample stimuli, Control Session (CS) with no telephone ringing, Landline Session (LS) with landline phone ringing, Mobile Session (MS) with mobile phone ringing. Results: The median RT in the study population was signifi cantly elongated (p < 0.001) in MS. In women and in men RTs were signifi cantly longer in MS than in CS and non-signifi cantly longer than in LS. Reaction times in CS, LS and MS were longer in women, however the differences were not signifi cant (p > 0.05). Conclusions: We think that the specifi c ‘bond’ between a person and their private phone can signifi cantly disrupt their attention and thus affect the attention-demanding activities.

Opis:
Community is a potent strategy if it is approached with the right mind-set and skills. A strong brand community increases customer loyalty, lowers marketing costs, authenticates brand meanings, and yields an influx of ideas to grow the business. Through commitment, engagement, and support, companies can cultivate brand communities that deliver powerful returns16. The findings of the study conducted by the authors show that most operators has the interactive Facebook pages and users can receive answer to their question in the reasonable time. Brand Engagement rates are the highest in Germany, France and Poland take the second place with quite similiar results, whereas England has definitely the lowest rates. Apart from this ranking, the overall level of engagement rate is low in comparison to the amount of fans, each fan page has. It means that brand strategies on Facebook should be improved to engage fans. Further studies might indicate reasons of this outcomes and engagement rates comparison in other sectors. What can be concluded according to this article is that although Facebook is the global platform, brand engagement rate within communities in the mobile network area is rather differentiated among countries and networks' brands. Using social media to build brand loyalty seems to be the upcoming challenge for all companies and the presence on Facebook should be taken seriously.

The aim of the contribution was to map the degree of smartphone addiction in adolescents by means of The Smartphone Addiction Scale (SAS-SV) short version designed by Kwon et al. (2013). The construct validity of the research tool was established by exploratory factor analysis. A unidimentional solution appeared suitable to work with. The internal consistency of the scale was determined by Cronbach’s alpha (0.831). 519 respondents aged 12 to 25 years (AM = 19.41; SD = 3.83) participated in the research. A statistically significant difference was confirmed in the degree of adolescents’ smartphone addiction by gender in favour of women, and by age, at which respondents got their first smartphones, in favour of those who got their smartphone at a younger age. The effect size of differences was weak. No statistically significant difference showed in the degree of smartphone addiction by school type attended by adolescents.

Introduction: The consistently growing number of mobile phone users has contributed to increasing interest in the effects of mobile phones on human health. Purpose: To assess the preferred health behaviors of mobile phone users. Materials and methods: The study included 175 mobile phone users and used standardized tools, such as the Multidimensional Health Locus of Control (MHLC) scale and the Health Behavior Inventory (HBI). Results: Most respondents had an impact on their own health (avg. 26.9 points). Respondents showed the highest level of health behaviors in relation to attitude, whereas the lowest level towards health practices. We distinguished three groups in the study population: with high (14.9%), low (47.4%), and average (37.7%) levels of health behaviors. We cannot unequivocally state that there is a statistically significant correlation between the occurrence of certain fungal genera/species on mobile phone and hand surfaces and the health locus of control. Conclusions: The respondents themselves mainly had an impact on their own health, and those in favor of this opinion attached greater importance to washing their hands. Respondents showed the highest level of health behaviors in relation to mental attitude, whereas the lowest level towards preferred health practices. Almost half of the respondents showed low levels of health behaviors, whereas almost every seventh respondent had high levels of health behaviors. No significant relationship was shown between the preferred health behaviors and the frequency of washing hands, the number of colonies and the isolation frequency of fungal strains collected from the surfaces of mobile phones and the hands of their owners.

This paper presents the use of new technical equipment by young adults (30 years old or younger), and the physical symptoms they have. The paper then analyses how the symptoms are associated with the use of computers and mobile phones, taking into account the background information. The study is based on a survey of 15 000 working-age (18–65) Finns. The responses (1563) covering young adults’ physical symptoms were analysed. Altogether 53.3% of all young adults had pretty often or more frequently pain, numbness or aches in the neck and 32.2% had aches in the hip and lower back. Women experienced more pain, numbness or aches in the neck (65.0%) than men (34.5%). The use of different computers at leisure quite often had an association with some symptoms in different parts of the body. In addition, exhaustion at work had associations with some physical symptoms. In the future, it is essential to note ergonomic reasons and exhaustion at work when young adults experience pain, numbness or aches.

As cell phone technology continues its rapid development, the device appears capable of contributing to student learning and improved academic performance. The recent rapid increase in cell phones has influenced multiple aspects of our daily lives, particularly those of Students. Therefore, the aims of the current study is to determine the influence of the mobile phone usage on academic performance among male and female students of Jahangirnagar University, Bangladesh. A face to face survey was conducted among 274 students which include 159 male students and 115 female students ranging from second year to fourth year from different departments of Jahangirnagar University, Bangladesh. Results depicts that gender, age and relationship with opposite sex have the significant positive effect on students’ academic performance. However, marital status, spending time on mobile phone, negative effect of mobile phone and application usage while studying has the negative effect on students’ academic performance. Cell phones are undeniably convenient, helpful tools for study and can be a hurtful source of distraction depending on the attitude and use pattern of a student. The author, however, suggests that the mobile phone designers must take into account how young people use cell phones for educational purposes.

Opis:
The continuous changing technologies of electronic devices, mainly mobile phones cause that their life is shorten from year to year (even to 8-12 months); that is way there is a constantly increasing amount of generated waste. Such waste treatment to recover mainly copper and other base metals should be really profitable. The process of metals recovery could be done using different methods including pyro- and hydrometallurgical process. The paper describes the research of leaching process of Printed Circuit Boards (PCB) coming from waste mobile phones. As a leaching agent sulfuric acid was used with addition of hydrogen peroxides. Experiments were carried out for different temperature, acid concentration and addition of hydrogen peroxide. As a result the concentration of copper, zinc, iron and aluminium in the obtained solution was measured. The results were discussed.

Food insecurity is quickly becoming a key topic in national and international debates. Consequently, series of studies have been conducted on food security and its determinants. However, none of these studies have measured food security among cocoa marketers and have considered the influence of public relations (PR) on food security among cocoa marketers in Nigeria Thus, this study measured food security status and determined the influence of PR strategies on food security of marketers. A combination of purposive and random sampling techniques were employed to select 100 respondents for this study. The analytical tools include: descriptive statistics, food security index and logistic regression analysis. The result revealed that majority of the sampled respondents were males with an average household size of 8 persons. The food security index indicated that 65% and 35% of the respondents were food insecure and secure respectively. The logistic regression indicated that about 53% of the total variation in food security of the wholesale cocoa marketers was accounted for by the estimated explanatory variables. Age of the respondents, marketing margin, household size, credit access and PR strategies were the critical determinants of food security among cocoa marketers in the area. Government should provide PR tools at subsidized rate as well as train marketers on the effective use of these tools. Policies to address irregular network and high airtime tariff challenges associated with the adoption of PR strategies in the country must be supported. Policy aimed at reducing household size should be encouraged.

The publication is based mainly on the results of a survey conducted in 4Q 2012 on a sample of 118 Cracow University of Economics students. The study confirmed that the Polish mobile commerce market is still at an early stage of development. Currently, only a relatively small percentage of consumers use mobile phones to make purchases of goods or services. The main reasons for this state of affairs include lack of awareness and knowledge among consumers about this form of shopping and their negative attitude.

Consumers’ attitudes are determined by many factors, one of which is a product brand. The objective of the paper is to present young consumers’ attitudes towards mobile phone brands. The ABC model of attitudes is the theoretical framework for the study. The research method was a paper-and-pencil survey (PAPI) on the sample of 250 respondents aged 18–25. The research showed that it is just the name of the brand that can affect consumers’ attitudes. It is a derivative of associations with the brands. The value of the attitude components is differentiated by brands. The affective component appeared to be the most important and the cognitive component – the least important. The findings show that gender and brand of respondents’ mobile phones also differentiate the importance of components of young consumers’ attitudes on the mobile phone market. Limitations and recommendations for further research are presented as well.
