Computers and Individual Health
Medical and physical effects of working long hours on computers are generally concern Vision problems and Muscle strain.
Electromagnetic Radiation (EMR)-electronic devices emit EMR but the strenght of the radiation and any possible harmful effects, fall off rapidly as you move further from the device, especially the display screen.
Ergonomics_? (The study of the interaction between people and machine).
Researchers recommendations-1
Check that overall illumination for computer equipment is less than the customary office lighting level (although lighting needs vary from person to person)
Adjust the characters on the display screen to contrast well with the screen background.
Minimize reflected glare on display screens by placing the screens so that windows and other sources of light are behind you.
Researchers Recommendations-2
Avoid white or light-colored clothing if it causes a reflection on the screen.
Take 15 minutes break/rest after 2 hours of continuous work (National Institute of Occupational Safety and Health).
Use an adjustable chair, which can be a vision aid by enabling you to sit at a proper angle (90 degree) to the display screen.
Place your reference material as close as possible to the display screen to avoid frequent large eye and head movements
Environmental issues raised by IT
Reduced energy consumption- Computers now control may of the heating systems in offices and factories so…..!!
Reduced wastage in industrial process
Saving trees- EDI has led to paper being eliminated in many offices so not only are the trees saved but the energy that went into the making of the paper is also saved.
Reducing car pollution- Teleworking (working at home using IT) means no longer have to travel.
Ethical, Moral and Social issues
Software theft- How many people could honestly say that all the software on their hard disks has been purchased by them?
Hacking-Many people see it as a challenge and not as an illegal activity.
Job losses- Is it right to develop new systems in the knowledge that staff will inevitably be made redundant?
Privacy- Your private life is becoming less and less private. (e.g. National Identity Numbers)
Where is security and Privacy?
Who are they ?
Are they exactly?
Surely not but….

Ethical, Moral and Social issues
Illegal pornographic material- illegal in some countries may be perfectly legal in others. The internet is a global system and it is difficult for single countries to make laws to control it.
Big Brother is watching you- misuse the system and adopt a ‘Big Brother’ attitude.
Ethical, Moral and Social issues
Computer game addiction- this solitary activity is affecting the social and educational development of such children. Many computer games do not mimic reality and often involve simulated violence.
Internet chatting addiction- Increased divorce rate in many countries like; Japan.

Intellectual Property Rights
Plagiarism-
The representation of someone else’s work as your own. You can be guilty of plagiarism. A student may be expelled from college.
It is very alarming in education especially in ICT based countries.
Trojan Horse & Viruses
A virus is a small program either stored on a disk by itself or appended to an existing files. You get it when you use disks from other users or download files over a network such as the internet.
A virus hiding in a program is called Trojan horse. When the Trojan horse program is run, the virus loads itself into the PCs memory. It can secretly attach itself to other files or programs or store itself on any other disks including the hard disk.
