Abstract
This research was conducted to examine the biomechanical features of currently used cash register designs in New
York State. Comparisons and conclusions about the designs are based on the current Occupational Safety and Health
Administration (OSHA) standards regarding supermarket cash registers. A total of 15 supermarkets were included in the study representing a cross-section of neighborhoods. Stores were measured for heights of the various work surfaces and reach distances to the commonly used components. Results revealed that none of the stores utilized biomechanically correct designs. Disregard for certain biomechanical aspects of the register design, specifically surface heights and reach distance may contribute significantly to a high risk for injury present in the modern day job of cashiers. Relevance to industry
This study highlights problems in the supermarket industry regarding compliance with ergonomic guidelines for supermarket cash registers. The findings suggest that, though advances have been made in register design, the newer models are not widely implemented and cashiers remain at risk for a variety of musculoskeletal disorders from currently used models. r 2004 Elsevier B.V.

Technology and Computers

...processing and storage of information. Do not think of a computer merely as the machine with the keyboard and the mouse, although that might be true for some types of computers. Embedded computers may be inside your household appliances, the video cassette recorder, the automobile, planes, trains, power plants, water purification plants, calculators, and even inside a few toys. These embedded computers are very small. They affect our lives each day. Why, even modern traffic lights operate with computers. They are all around us. Think of additional ways in which computers affect our lives each day. Every organization somehow use(s) a computer to run the organization. Some of the places are hospitals, schools, fire department, banks, stores or supermarkets, stock exchange, police department, insurance companies, transport companies, and government agencies etc. What is a computer? A computer is many things to many people, depending on what it is being used for. At one time the computer can be a machine which processes the payroll, then it can be a machine which tabulates students’ grades, then a machine which stimulates the loading on a bridge, then it processes insurance policies, then it plays chess, and so on. It is important to note that all the above tasks, and many more, can be performed by the same computer. Definition: A computer is an electronic device that performs four functions: it inputs data (getting information into the machine); it...
