Glossary

3. Ergonomics and health issues
Lack of physical activity
obesity
hypertension (high blood pressure)
diabetes
increased risk of heart disease.
Repetitive Strain Injury (RSI)
Carpal tunnel syndrome (CTS)

4. Ergonomics and health issues
Repetitive Strain Injury (RSI)
A class of injuries (to tendons, etc.) caused by repetitive actions.
Carpal tunnel syndrome (CTS)
CTS is caused by inflammation of the tendons in the wrist.
Ergonomics
Refers to the study and design of workplace for comfort and safety of people in work environments.

5. Ergonomics and health issues
Keyboards
to promote a more natural position for hands and wrists, with the palms turned slightly toward each other rather than flat relative to the keyboard..

6. Ergonomics and health issues
Mice
Used extensively in a GUI environment and requires users to hold their hands in unnatural, awkward positions for long periods of time.

7. Ergonomics and health issues
Healthy practices
Sit correctly
Adjust the height of your seat or table
Adequate ventilation/air circulation
Mouse and keyboard are on same level, close
Monitor is positioned at the correct level
Prevent eye strain
Take regular breaks

8. The need for green computing
Energy efficiency- problem
Electricity required by computers
Electricity comes from burning fossil fuels
Global warming

9. The need for green computing
balance producing ‘faster’ equipment with the increased use in power and heat
produce ‘green’ products - utilise less power
power-saving
Energy efficiency- ways to improve

10. The need for green computing
reduce toxins in technology manufacture
E-waste
BROKEN OLD HARDWARE
TOXINS
SEEPS INTO WATER TABLE
ENVIRONMENTAL DAMAGE
force re-cycling of e-waste

11. The need for green computing
Paperless office?
Paper
Paper uses trees
Chemicals
BIG carbon footprint

12. The need for green computing
Paperless?
Small portable devices with high quality displays and
long battery lives only arrived recently
Digital Divide – these devices not affordable enough
Hard copy is the cheapest and easiest way at moment
Paper cheaper and less risky than
large visible video displays
Hard copies - non-electronic
backups of data/information

13. The need for green computing
Tips on how to practice green computing
Switch off computers and devices you are not using
Try and avoid the senseless wasting of paper
Try and upgrade or give away old hardware, not
throw away
Send old ink cartridges back to manufacturer
Refill and reuse old ink cartridges

14. The impact of global e–communication
Computers have changed the way we communicate
Faster
in seconds
talk to anyone, anywhere in the world
video chats and conferences
send huge files instantly anywhere
message to millions of people instantly

15. The impact of global e–communication
Computers have changed the way we communicate
Cheaper
VoIP and Skype cheap
huge documents by cheap /almost free

16. The impact of global e–communication
Computers have changed the way we communicate
More effective and reliable
quality of received identical to sent.
locate data/information almost instantly using the Internet
business transactions anywhere at any time
social networking
