 note = {Departmental Bulletin Paper, Risk structure for teenagers in Japan has changed recently. In a smartphone age, it is growing more difficult than ever to shut out harmful information from teenagers with filtering services. As a result many teens are exposed to problematic or noxious contents in cyberspace. Besides, they are exposed to risk of addiction to excessive Internet use, especially to on-line games.\nThis paper attempts to investigate the risk structure for present schoolchildren on a survey we executed in Maebashi city, Gunma prefecture.},
