Summary 45

4VNNBSZ5IFQSFTFOUDPOEJUJPOT • The use of the smartphone is communication mainly
• The main use is narrowed down to Twitter and LINE • With the others who do not know it by sight with planning communication using SNS can interface it 46

4VNNBSZ5IFQSFTFOUDPOEJUJPOT • The student uses the service that information can
send to unspecified number of the general public such as Twitter for the sense that only a fellow thinker sees • An encounter comes out of interchange with the unspecified number of the general public in Twitter • It is difficult to ascertain a partner with the malice (because inexperienced as experience) 47

4VNNBSZ5IFQSFTFOUDPOEJUJPOT • When a partner is false, there is the
risk that watches Twitter, and approaches, and is rolled up in a crime • There is the risk to be connected by the method called the communication that is a secret room using LINE for an evil deed after having approached • Concealment communication not to understand is completed from a parent and a school 48

4VNNBSZ.FBTVSFT • I wear a scary sense to protect the
body because I stayed to meet because a murder case of Mitaka was scary • Because there are not checks such as the age, in SNS such as Twitter, do not give the partner who can hide birth and parentage information • I instruct a challenger that there is not it to get attention easily • Have a fear toward a person to approach • Are structure and an action to prevent you from becoming concealment communication not necessary? 49
