A-KASTANIA
Teleapplications can be defined as : Human performance systems that integrates telematics for:
1.- Training purposes ( Teletraining )
2.- Medical assisance ( Teleteaching )
3.- Work efficiency ( Teleworking )
Organization enviroment is mandatory for a successfull innovation . since choice of technology is not just a technical decision but requires values jugement as well . Furthermore any Teleapplication ( mission oriented policy ) required three main actions :
I.- PLANNING
II.- DESIGN
III.- DELIVERY
I.- PLANNING : Technology may be use within the system in two ways
a) To be added to the existing one
b) To replace the existing technology
- Changing technology
- Changing the methods of working
1. Structural changes in the organization
2. Changes in the individual work practice
3. Changes in the decision making powers
II.- DESIGN : Remain educational and operational rationals for using technology
1. Work enviroment ( designed with a telecommunication engineer and expert on security (see Chapter 8 )
2. Staff enviroment ( desgined with an architect )
III.- DELIVERY of efficient teleservices require a control and monitoring node ( STUDIO ) to
- Control include
- schedule access
- update and optimized systems according to new technology and links
- Monitoring include : acquisition, transmission, analysis and storage information

A service delivery have to assure that:
all operating conditions are in place
will be run efficiently
it sound in order to insure the system continuity

Therefore :
The generic applications that can be included under the umbrella
of Teleservices for Health Care are :
S. WENGER
In many of these service the underlying condition is the
capability to provide the service simultaneously to different
points and users in a MULTICONFERENCE enviroment that assure QoS
( quality of services)
Apart from ATM,DQDB,FDDI ( which standards are not fixed yet ),
the ISDN is the only standardized network available at the
present moment for multimedia conferencing with QoS.
Nevertheless ISDN device are point ot point designed terminals (
H.320 standard ), insuficient and not able to do the time
consuming multiplexing task required for a multiconference with
various users. The only possible Multipoint Communication require
to connect each terminal through a special end-point routing
device called MCU ( Multiconference Unit ).
MULTICONFERENCE UNIT ( MCU )
The MCU is capable of handing various simultaneous data
streams and in large multiconferences various MCUs can be
connected.
The MCU ( H.231 standard ) accomplish part of the task
reserved to a Studio Manager by means of the H.243 protocol for
exchange and conference control together with the optional
conference control mechanisms ( T.124, T.128 ) for the "
floor control strategies " using mixing or switching methods
for audio and only switching for video.
Its CPU controlled the audio and Videoprocessor unit and stablish
management, connections, authorizations , income and outcome
users and similar tasks.

Teleworking enviroment can be solved with CSCW based on :
- Client/Server paradigm
- small community with an agent giving services together with one or more personal agents
- Multiagent paradigm
- each agent have specialized functions
each agent can be service provider
Comunity of agents ( human-systems ) exchanging
data,services,expertise in a common enviroment are known as AGENCIES
:
ACL = agent communication language - KQML/ KIF
Users ( humans ) interact with other agents through specialized
agents called : PERSONAL AGENTS or Personal Assitants
The AGENTS can be divided into :
