1. The effects of using IT INSTRUCTOR: TR. THET ZIN 1

2. Microprocessor- Controlled Devices 2

3. Positive and Negative Effects of using IT  Lifestyle  Leisure time  Physical fitness  Data security  Social interaction NIEC Tachileik 3

4. Labour-saving devices  Automatic washing machines  Microwave ovens  Cookers  Automatic dishwashers  Robotic vacuum cleaners  Bread-making machines  Smart fridges and freezers NIEC Tachileik 4

5. Other devices  Alarm clocks  Television sets  Central heating and air-conditioning systems  Home entertainment systems  Mobile phones and tablets NIEC Tachileik 5

6. Advantages and disadvantages of MC labour-saving devices Advantages  Automatic  More leisure time  No need to stay home for chores  Automated burglar alarms  Smart fridges and freezers Disadvantages  Unhealthy lifestyles  Lazy  Lose household skills  Risk of cybersecurity threats NIEC Tachileik 6

7. General Advantages and disadvantage of using all MC devices Advantages  Save energy  Easier programming to perform task Disadvantages  Wasteful society  Complex to operate  Wasteful of electricity NIEC Tachileik 7

8. Data Security issues  MC device connected to the internet can lead to cybersecurity issues.  If you can remotely control from anywhere, so can a hacker.  Devices are default set and no password.  Personal details, holiday dates lost and break in your house  Automatically order food from market, then hacker can gain key data, such as credit card numbers.  Make sure to manage different passwords and install updates NIEC Tachileik 8

9. Social interactions Positive  Easier to make new friends using chat rooms  Easier to find people who share similar interests/hobbies  Less expensive to keep in touch using VoIP technology Negative  People do not meet face-to-face as much  Lack of social interaction & more anxious in real life  Behave differently when interaction online NIEC Tachileik 9

10. Monitoring and controlling transport  Monitoring of traffic on motorways  Congestion zone monitoring  Automatic number plate recognition (ANPR)  Automatic control traffic lights  Air traffic control systems  Railway signaling systems NIEC Tachileik 10

11. Control of smart road systems and smart signs  Smart motorways  controlled by a central computer system  Monitoring and control of the traffic and displayed on the motorway signs NIEC Tachileik 11

12. Rail and air line network control systems  Safely coordinating the large number of trains and aeroplanes entering and leaving stations and airports is a complex task.  Computerized monitoring systems is possible to run a more efficient timetable under total computer control.  Train and aeroplane journeys are so safer because human error is removed. NIEC Tachileik 12

13. Advantages and disadvantages of transport monitoring and control systems Advantages  Reduce traffic jams  More efficient, more cars, trains, aeroplanes can use transport network  Traffic offences using ANPR  Stolen cars and criminals can be spotted using ANPR  Minimise huma error Disadvantages  Hacker gain access and cause disruption  If systems fails, everything would be standstill  Poorly designed systems could compromise safety  ANPR can easily track innocent people’s movement. Then, who has access to that data? NIEC Tachileik 13

14. Advantages and disadvantages of autonomous vehicles Advantages  Safer, human error is removed  Better for the environment  Reduced traffic congestion  Increased lane capacity  Reduced travel times  Stress-free parking for motorists Disadvantages  Very expensive  Fear of hacking into the control system  Security and safety issues (software glitches , software updates)  Make sure the system is well-maintained at all time  Driver and passenger reluctance of new technology  decrease jobs for taxi drivers NIEC Tachileik 14

15. Advantages and disadvantages of autonomous trains Advantages  Improves the punctuality of the trains  Reduced running costs  Improved safety, human error is removed  Minimises energy consumption  Possible to increase the frequency of trains  Easier to change train scheduling Disadvantages  Fear of hacking into the control system  System does not work well with very busy services  High capital costs  Ensuring passenger behavior is a acceptable  Passenger reluctance of the new technology  Need for CCTV to monitor railway stations NIEC Tachileik 15

16. Advantages and disadvantages of pilotless aeroplanes Advantages  Improvement in passenger comfort  Reduced running costs  Improved safety,  Improved aerodynamics at the front of the aeroplane Disadvantages  Security aspects if no pilots on-board  Emergency situations during the flight may be difficult to deal with  Cybersecurity threat  Passenger reluctance to accept new technology  Software glitches NIEC Tachileik 16

17. Health Risks of using IT Equipment 17

18. Back and neck strain Causes  Sitting in front of the computer screen for long periods of time Reduction  Use fully adjustable chairs to give the correct posture  Use foot rests to reduce posture problems  Use tiltable screens, raised to the correct height, to ensure the neck is at the right angle NIEC Tachileik 18

19. Repetitive Strain Injury (RSI) Causes  Damage to fingers and wrists caused by continuous use of a keyboard or repetitive clicking of mouse buttons Reduction  Ensure correct posture is maintained  Rest your wrist  Take regular breaks (+exercise)  Use Ergonomic keyboards  Use voice-activated software NIEC Tachileik 19

20. Eyestrain Causes  Caused by staring at a computer screen for too long or by having incorrect lighting in the room Reduction  Change LCD if CRT screen is used  Take regular breaks (+exercise)  Use of anti-glare screens  Eye test on a regular basics NIEC Tachileik 20

21. Headaches Causes  Caused by incorrect lighting, screen reflections, flickering screens and so on Reduction  Use of anti-glare screen  Take regular break (+exercise)  Eye test on a regular basics NIEC Tachileik 21

22. Ozone Irritation Causes  Caused by laser printers in an office Reduction  Proper ventilation should exist to lower the ozone gas levels to acceptable values  Laser printers should be housed in a designated printer room  Change to using inkjet printers where possible NIEC Tachileik 22
