製紙産業における計装の自動化は，約30年前からDCS（分散型制御システム）とQCSが主役となっており，省人化や品質向上・制御性向上を実現してきた。一方，工業用監視カメラや内線電話・ページングシステム等の周辺機器は，DCSとは別のシステムとして単独で設置し運用してきた。
LANの高速化，Webカメラの高性能化，VoIP技術（Voice over Internet Protocol）の高度化などに伴い，昨年稼働したN10マシンでは，監視カメラ・内線電話・IP無線電話・ページングシステムおよびモバイルDCSを1つの通信ネットワーク上に構築し，操作性向上・省力化を実現できた。その使用経験について紹介する。

Human body dynamography(HBD) is proposed as a convenient system for analyzing and evaluating human body motions specifically the torque acting at joints of a human body. Torque intensity is visually displayed using a color scale. A kinetic model of the human body, consisting of fifteen rigid cylinders equivalent to the body segments and the equations of motion, is derived to estimate each torque during joint action. A sequence of motions in both the frontal and sagittal planes is simultaneously taken by two video cameras, and the coordinates of individual joints are digitized with a PC. Visualization of torque was tested on the planar motions in a popular physical exercise of a Japanese radio program. Rings centered on individual joints were drawn on a skeletal model, and colored corresponding to the magnitude of torque. Torque was normalized by the cross·section area (Normalization 1) and volume (Normalization 2) of each segment. Additionally, HBD was compared with thermography to evaluate the normalizations.
