Lecture 1 - Technological Society Flashcards
Define ergonomics
A discipline that involves arranging the work environment (i.e. home, school, at one’s job) to fit the people in it.
What are repetitive stress injuries?
injuries resulting from excessive and repeated physical stresses on musculoskeletal system
List the key concepts of a technological society
- Specialization of labour
- Energy derived from machines
- Standardization and interchangeability of parts
- Use of machines
- Mass production and mass consumption
- Use of the assembly line
- Computers and computer networks
Key concept 1: Specialization of Labour
- increased degree of specialization
Key concept 2: Energy Dervied from Machines
- 1776:Invention of steam engine
- Electric motor
- Internal combustion engine
- Computer
- Modern communication
Key concept 3: Standardization and Interchangeability of parts
Standardization
– Reduces number of choice available
– Can reduce production costs
– Is often opposed by sales departments
* Interchangeability of parts
– Requires accurate machine tools
– Began in 1820s–1850s and spread gradually.
Key concept 4: Use of Machines
- Machines reduce the effect of distance on transport and communication
- In production, electric motors and computers have
replaced human labor - Humans are now the supervisors of machines
Key concept 5: Mass Production and Mass Consumption
- Mass production and consumption are interdependent.
- High productivity permits high wages.
- High wages allow workers to purchase products.
- High sales volumes permit high wages.
- Reduces product costs
- Products not designed to last long (planned obsolescence)
Key Concept 6: Use of Assembly Line
- Product moves past stationary machines and workers.
- Sequence of operations is standardized.
- Machines are specialized.
Key Concept 7: Computers
- Developed in1940s
- Stored programs (processor and memory)
- Transistor
- Constantly increasing speed and decreasing cost
- Make machines more flexible and free up workers to supervise
Information and Communications Networks
- One-to-many networks
- Many-to-many networks
- The Internet
- Mobile phones, hand-held computers
- Virtual offices
- International interaction
- Direct computer-to-computer interaction
