INFLUENCE IN HEALTH AND ENVIRONMENT

2. The computer is a vital tool in many
different jobs and activities, for adults
and children. However, long periods of
using a computer can increase your
chance of developing in injury.

3. Many computer-related health
problems are minor and
caused by a poorly designed
work environment

4. 1. Ergonomics – the study of designing and positioning computer
equipment, has suggested a number of approaches to reduce
these health problems. Ergonomic is a approach which puts
human needs an capabilities at focus of designing technological
systems.
2. Flexibility – is a major component of ergonomics and important
feature of computer devices. People differing sizes and
preferences require different positioning of equipment for the
best result.

5. 1. Task variety – alternating task within a job minimizes
repetitive activities and reduces wear and tear on the body
2. Appropriate work pace – When the pace of work is too fast,
the body has very little recovery time between repetitive of
forceful movements.
3. Work Breaks – Resting, stretching or changing position
between tasks helps prevent muscle fatigue and injury
4. Rest Breaks – Stopping work for a period of time during the
day provides an important physical and mental break.
5. Training and education – Acquiring the appropriate skills to
do a job safety and efficiently prevents accidents and injury.

6.  Keep tools, materials, and equipment within easy reach.
 Work at proper heights in relation to your body; use adjustable
workstations
(chairs, tables, flatforms).
 Work with a good, comfortable posture.
 Reduce excessive repetition in task and activities.
 Avoid excessively forceful movements e.g., striking computer keys with
too much force and lifting heavy loads.
 Minimize general fatigue by taking appropriate work and rest breaks.
 Maintain comfortable environment (heat, light, humidity).
 Organize your work processes efficiently.

7. Many computer components can be recycled.
Specialized companies that recycle computers
sell usable materials and safety dispose of
hazardous materials. Some computer
manufacturers offer recycling possibility by
offering old for new computer exchange.

8. Energy Management
Today, there is an estimated 7 billion people. We consume a
lot of energy and resources. Without energy, it would be
difficult to imagine today’s society. It is one of the key factors
in our survival and way of life. Therefore, effective energy
management needs special emphasis and it is done on both
macro and micro levels. In terms of computers, energy
management is integrated into an operating system, which
allows user to make adjustments in order to save energy

9. Building Management
Modern Buildings have computer-controlled environment systems in
place.
An air-conditioning system keeps the temperature at a reasonable
level.
Solar panels reduce the consumption of electricity from national
grid.
Energy monitoring displays help staff know what is using up the
power.
LED lighting uses only a fraction of energy without sacrificing
luminance of brightness.
Water conservation systems are designed to reuse water, especially
in industrial factories.

10. SMART METERS
In general, people at home do not know how much energy
is being used at any moment and what is using it. The
idea of smart energy consumption meter is to keep track
of energy use minute by minute. A display in the home
then shows what is going on.
E-Waste
Electronic waste or e-waste can include all electronic and
electronic products that are no longer wanted or useful.
