[Participation of anesthesiologists in the Internet].

The author classified the e-mail addresses of the mailing list "Masui Discussion List" users. The result indicates that the types of the participation of those users in the Internet are classified into the following three: (1) Use of the network of employment places such as universities and hospitals or their facilities, (2) Via the BBS (Bulletin Board System) host, and (3) Contract with a network service provider. The author estimates the following: Type (1) occupies about half of the whole types. Types (2) and (3) occupy about a quarter of the whole types, respectively. If the network of the employment place cannot be used to access the Internet, dial-up IP connection can be made by contracting with a network service provider. To make such a connection, a multimedia personal computer, dial-up IP connection software, a high-speed modem or a terminal adapter, and variety of Internet application software such as World Wide Web browser are required in addition to the telephone line (analog or ISDN).
