In the 21C information & communication cofiguration, the mobile communication service has been rapidly developed, the number of mobile phone subscribers amounts to 31,000,000 and the number of wireless internet subscribers amounts to 27,190,000 as of July. 2002. It shows clearly that the central axis of future communication service market is changed rapidly into mobile communications from conventional telephone. The other side, as the rapid development of mobile communications, the improvement of wave propagation environment and communication quality were appeared with an important problem. To solve the problem, a technical study and a development are being repeated. But, since a legal restrictions of the mobile phone are relatively many than the wire phone, it has a great difficulty that mobile communication provide its subscribers with a better quality service. In this study, I examine to restriction connected with the cases of controls according to installation, operation of base station and propose a plan for relax restriction for mobile communication service.

This study attempts to explore critical dimensions of digital inequality experienced by adolescents. Data was drawn from the self-reported survey of 1,105 students in elementary, middle and high schools. The findings indicate that there are some variations in the technical means, autonomy of use, and social support concerning the internet use of adolescents -- measured by the place of use, parents' supervision, encouragement and technical assistance -- by students' sex, school levels, mothers' education and maternal employment. Second, students' sex, school levels, mothers' education, and the degrees of parents' supervision and encouragement have substantial impacts on the amount of time spent on internet use and the extents of internet use for various purposes. Finally, male students, and those who have mothers of higher educational level and have actively used the internet for communication, technical skills development or learning purposes, tend to report higher digital efficacy. These results imply that government, schools and the civil society should exert more efforts to expand public facilities for enhancing free and autonomous access, opportunities of internet education for parents, and availabilities of suitable contents in order to ameliorate digital inequalities among adolescents.
