  • The purpose of the present study was to examine the causal relationship between aggression and mobile phone dependency among high school students and to test the mediating effect of self-esteem, and to draw out implications in order to encourage proper use of mobile phone. In this paper, we proposed a research model between aggression, self-esteem and mobile phone dependency. The present study analyzed the fourth, fifth, and sixth wave data from KCYPS 2010, using the structural equation modeling. The primary results were as follows. First, the effect of high school students' aggression on mobile phone dependency was not significant. Second, high school students' aggression had a significantly negative effect on self-esteem. Third, high school students' self-esteem had a significantly positive effect on mobile phone dependency. Fourth, high school students' self-esteem could be a significant mediator between aggression and mobile phone dependency. In conclusion, theoretical and practical suggestions were discussed in order to solve the problem of adolescents' mobile phone dependency.

  • The purpose of this study was to examine the effects of adolescents' mobile phone dependency on depression and aggression and to identify mediating effects of parenting attitudes and peer relationships. This study used data from the 4th and 5th waves of 2010 KCYPS (Korean Children and Youth Panel Survey). Structural Equation Model(SEM) was conducted to examine the mediating effects of parenting attitudes and peer relationships. The results showed that adolescents' mobile phone dependency had positive effects on depression and aggression. In addition, the relationship between adolescents' mobile phone dependency and depression was partially mediated by parenting attitudes and peer relationships. The relationship between adolescents' mobile phone dependency and aggression was also partially mediated by parenting attitudes and peer relationships. Based on these findings, further suggestions are provided to reduce adolescents' depression and aggression by decreasing mobile phone dependency and improving parenting attitudes and peer relationships.

  • This study examined the mediating effect of depression on the relationship between over-control parenting styles and mobile phone dependency among children. The 5th-year longitudinal data from the Korean Children & Youth Panel Survey (KCYPS) were collected from 4th grade elementary school students. The data were analyzed by the structural equation modeling and bootstrapping. The results of this study were as follows. First, there is a positive path from over-control parenting styles to depression, from depression to mobile phone dependency, and from over-control parenting styles to mobile phone dependency. Second, depression had a mediating effect on the association between over-control parenting styles and mobile phone dependency. Based on these results, more study of elementary school students' reliance on cell phones is needed.

  • The purpose of this study is to investigate the differences of the mobile phone overuse by gender and school levels. For this study, 565 middle and high school students in Gyeonggi province answered the self-report survey, 253 students were extracted as an overuse group, and the data were analyzed by one-way MANOVA. The results showed that 'daily disturbance' was a common major factor in gender and school level difference and 'school life disturbance', 'with draw' and 'tolerance' were added in school level difference. Based on the results, this study suggested users' characteristics such as gender and school level should be taken into prevention and treatment of mobile phone overuse.

  • The purpose of this study was to examine the effects of self control and social support on the mobile phone dependence in elementary school students. The subjects were 392 children(187 boys, 205 girls) in 5, 6th grade from two elementary schools in Gyeonggi-do. The mobile phone dependence was assessed by the Mobile Phone Dependence Scale(Ko Seong-Ja, 2012), self control was measured by the Self-control Scale(Nam hyeon-mi, 1999) and social support was assessed by the Social Support Scale(Han mi hyun, 1996). Data were analyzed using descriptive statistics, t-test, Pearson correlations and hierarchical regressions. The major results of this study were as follows: First, there was no significant difference in mobile phone dependence by sex of the children. Second, children's mobile phone dependence were correlated with self control and social support. Finally, children's self control, family support and peer support significantly explained the mobile phone dependence. But peer support appeared to have negative corelation on mobile phone dependence, but appeared to have static effect in regression result by suppressor variables. So it needs to explore statistical function of suppressor variables in follow-up studies. Also research of this study indicate that self control enhancement program should be developed and parents should communicate more frankly and affectively with their children in order to prevent children's mobile phone dependence.

  • Purpose: The purpose of this study was to investigate the relationship between cell phone dependency and aggression in elementary school students with the mediating effect of leisure activities in South Korea. Methods: Data were cross-sectional in study design with 1,555 fourth grade elementary school students participating in the 4th-year Korean Children and Youth Panel Survey. Data analysis was performed using the SPSS/WIN 23.0 and AMOS 21.0 program. Results: Cell phone dependency has a significant effect on aggression, but it did not act as a control variable in the relationship between the protective factor, weekly book reading time and the amount of daytime play with aggression. Weekly entertainment time and weekly TV and video viewing time had a significant statistical effect on aggression, thus this study confirmed that cell phone dependency acts as a control variable in relation to aggression. Conclusion: As the entertainment time for elementary school students, the time spent watching TV and videos play a negative role, it is necessary to prepare a leisure activity management practice and strategies with an emphasis on entertainment time as well as, TV and video viewing as elementary school students' leisure activities for a healthy school life.

  • For the last half a century, the personal computer and software industries have been prosperous due to the incessant evolution of computer systems. In the 21st century, the embedded system market has greatly increased as the market shifted to the mobile gadget field. While a lot of multimedia gadgets such as mobile phone, navigation system, PMP, etc. are pouring into the market, most industrial control systems still rely on 8-bit micro-controllers and simple application software techniques. Unfortunately, the technological barrier which requires additional investment and higher quality manpower to overcome, and the business risks which come from the uncertainty of the market growth and the competitiveness of the resulting products have prevented the companies in the industry from taking advantage of such fancy technologies. However, high performance, low-power and low-cost hardware and software platforms will enable their high-technology products to be developed and recognized by potential clients in the future. This paper presents such a platform for industrial embedded systems. The platform was designed based on Telechips TCC8300 multimedia processor which embedded a variety of parallel hardware for the implementation of multimedia functions. And open-source Embedded Linux, TinyX and GTK+ are used for implementation of GUI to minimize technology costs. In order to estimate the expected performance and power consumption, the performance improvement and the power consumption due to each of enabled hardware sub-systems including YUV2RGB frame converter are measured. An analytic model was devised to check the feasibility of a new application and trade off its performance and power consumption. The validity of the model has been confirmed by implementing a real target system. The cost can be further mitigated by using the hardware parts which are being used for mass production products mostly in the cell-phone market.
