The analysis revealed several notable points related with Internet applications by SMCs that , although SMCs strongly feel the need for the use of Internet. -the level of recognition for the existence of the Internet was relatively low -the time used was also at low level -the job which uses Internet was mainly marketing related -and the fields applied were concentrated in those of search and e-mail.
