The purpose of this study is to find the correlation between authoritative parenting attitudes, emotional bonding of adolescents with parents, impulsiveness and cellular phone addiction. The paper will also explore the mediating role of impulsiveness between adolescents' emotional bonding with parents, authoritative parenting attitudes and cellular phone addiction. The subjects were made up of 237 adolescents. The data were analyzed with frequency, ANOVA, Pearson's correlation and structural equation modeling by PASW and AMOS. The instruments used were Lee et al. (1997) Parenting Attitude, Hudson (1982) Child's Attitude Toward Parent (CATP), Lee (2001) BIS (Barnett Impulsiveness Scale) and Lee (2008) Cellular Phone Addiction. The major findings were as follows: the sex of the adolescents was significantly different with cellular phone addiction and their family economic status was significantly different with adolescents' emotional bonding with parents and cellular phone addiction. Authoritative parenting attitude was negatively correlated with adolescents' emotional bonding with parents and positively correlated with impulsiveness and cellular phone addiction. Emotional bonding of adolescents with parents was negatively correlated with impulsiveness and cellular phone addiction. Adolescents' emotional bonding with parents influenced impulsiveness and cellular phone addiction negatively, and impulsiveness mediated the effects of adolescents' emotional bonding with parents, authoritative parenting attitude and cellular phone addiction. Authoritative parenting attitude influenced adolescents' impulsiveness and cellular phone addiction positively, but impulsiveness influenced cellular phone addiction positively. In conclusion, it is important to intervene in adolescents' cellular phone addiction through special education programs and counseling to build adolescents' emotional bonding with parents and to reduce impulsiveness.

In Korea, the car mobile phone service had started in 1961 and with this Korea Mobile Telecommunications Services was established in 1984. Its service was mainly focused on the mobile phone service for the car which led the popularity of the full-scale mobile phone service. There are many kinds of materials, colors and patterns which are the elements of surface coating techniques. In light of that, we are focused on the UV coating that is ranked as an important part of the techniques in this study. In the first, the use of various materials for the cellular phone and surface processing techniques for the cellular phone were searched. On the basis of the results, the experiments of actual consumer experience with the exfoliation of the surface were done and through that we proposed the best way of processing the surface for the cellular phone and the materials. The result of the Wear Test showed that thick coating was detached more slowly and each company differed in their results with UV paints despite the same thickness of UV coating. The seal (UV) exfoliation of cellular phone is deeply related with the film thickness and the film formation when the users use the cellular phones and the exfoliation of the cellular phone surface will be decreased if the manufacturers meet the best conditions for the cellular phone.

The aim of this study was to identify the differences in cellular phone dependency and its use levels of usage purposes according to children's gender, and also to analyze the differences in individual and interpersonal relations development due to cellular phone dependency in children based on gender. Using the first year data of the Korean Child and Youth Panel Survey(KCYPS) 2010, this study analyzed 1,604 fourth graders who have their own cellular phones. For statistical analysis, descriptive statistics were calculated and mean difference analyses were conducted. The results showed that there was no difference between boys and girls in cellular phone dependency. The girls' total phone use level was higher than that of boys and meaningful gender differences in the phone use levels were found in the five phone usage purposes. In both boys and girls, the higher phone dependency groups demonstrated higher levels of phone use in more than eight usage purposes, lower self-resilience and self-regulating learning ability, and less positive peer and teacher relations. These findings show the importance of being concerned about and educating children in the fourth grade about the proper uses of cellular phones.

The camera cellular phone has a large portion of cellular phone market in recent year. The variety of a customer demand makes a fast model change and the spatial resolution is changed from VGA to multi-mega pixel. The 1.3 mega pixel (MP) camera cellular phone was first released into the Korean market in October 2003. The major cellular phone companies released a 2MP camera cellular phone that supports zoom function and a 2MP camera cellular phone is settled down with the Korea cellular phone market. It makes a keen competition in price and demands automation for phone camera module. There is an increasing requirement for the automatic assembly to correspond to a fast model change. The hard automation techniques that rely on dedicated manufacturing system are too inflexible to meet this requirement. Therefore in this study, this system is designed with the flexibility concept in order to cope with phone camera module change. The system has a same platform that has X-Y-Z motion or X-Z motion with ${\mu}m$order accuracy. It has a special gripper according to the type of a component to be put together. If the camera model changes, the gripper may be updated to fit for the camera module. The controller of this system acquires the data sets that have the information about the assembly part by the tray. This information is obtained ahead of an inspection step. The controller excludes an inferior part to be assembled by using this information to diminish the inferior goods. The assembly jig used in this system has a function of self adjustment that reduces the tact time and also diminish the inferior goods. Finally, the intelligent assembly system for phone camera module will be designed to get a flexibility to meet model change and a high productivity with a high reliability.

Purpose: The purpose of this study is to investigate influence of cellular phone videos and games on dry eye syndrome in university students. Methods: A randomized comparison group pre-post design is used. Sixty university students were randomly assigned to either a video or a game group. Frequencies of blinking, dry eye symptoms scores and amounts of tears were measured. Thirty subjects watched cellular phone video programmes and the other 30 subjects played cellular phone games for 61 minutes. In addition, frequencies of blinking were measured three times during treatment, once immediately after a treatment and twice at an interval of 20 minutes after subsequent treatments. Results: Post-test scores of frequencies of blinking significantly decreased, dry eye symptoms scores including amounts of tears significantly increased greater than pre-test scores in both groups. But there were no significant differences between the groups. Frequencies of blinking were significantly different with respect to the time spent using cellular phone. In both groups, the lowest frequencies of blinking were shown after 40 minutes of cellular phone use. Conclusion: This study shows that using cellular phone has negative influence on dry eye syndrome and eyes require a resting period after cellular phone use over 40 minutes.
