Importance Of Ergonomics

2.0. Concept of Ergonomics and it Important on Human Body
In terms of ergonometric comfort integrates a sense of well-being with health and safety conversely; discomfort could be related to biomechanical factors involving muscular and skeletal system (Zhang et al., 1996). The comfort, physical health, well-being and performance of people can be increased by designing equipments, furniture and other devices according to the needs of the human body. One of the conditions to support productivity is to ensure that work spaces and equipment that people use conform to the anthropometric and biomechanical characteristics of the users (Metin et al., 2008). Discomforts of muscle contracture of neck and back problems are due to sitting for a long time

The aim of this field of ergonomics is to improve productivity and enhance employee satisfaction, health and safety.
2.2 BENEFIT OF ERGONOMIC
Ergonomic improvements to the work environment are primarily used to create a safer and more healthful work environment; companies may experience other benefits, including:
• increased productivity
• increased work quality
• reduced turnover
• reduced absenteeism
• increased morale
From a safety perspective, Gyekye (2006) emphasizes that environmental conditions affect employee safety perceptions which impacts upon employee commitment. Similarly, extensive scientific research conducted by Roelofsen (2002) has also yielded indications suggesting that improving working environment results in a reduction in a number of complaints and absenteeism and an increase in productivity.

2.3 Sitting and Back Discomfort
The physical causes of back discomfort or cumulative back pain are believed to stem from the same kinds of ergonomic stresses, or risk factors that cause musculoskeletal disorders (MSDs) of the upper
