astute service providers realize that the continued support of legacy X.25 and asynchronous network element using separate operations network is cost (141) . For example, the maintenance of multiple networks can require additional staff. Often, this staff must be trained on multiple vendor technologies, sometimes requiring parallel groups specializing in each (142) . Hence, additional maintenance procedures must be maintained and administrative records are (143) . The duplication of transport facilities to carry (144) network traffic is an inefficient use of resources. And not surprisingly, more technologies installed in a central office means the necessity for more physical space and an increase in power connections and power consumption, migration of these (145) network elements to IP-based DCns is alogical strategy.

One study conducted by a psychologist (121) of interviewing workers before and after the installation of a robot. The robot was used to control a matching process of stamping and assembling metal parts. Prior to installation, much of the work done by skilled machinists. After installation, the robot did the work, but the workers controlled the robot through the robot through a control panel. The results of the study indicated that the workers praised the robot (122) eliminating the physical labor and fatigue (123) the manual operation, but complained of more and continued stress. Prior to installation of the robot, there was time for talking or short periods of relaxation between jobs. Now, however, because of the speed of the robot, there was a need for constant scanning and monitoring of the operation (124) performed by the robot has the installation of the robot created a better work environment Has the change from physical labor to mental stress resulted in an improved (125) of life Much additional research is necessary.
