  on types and levels of implementation of legislation,478 on social insurance developments, the influence 
  of globalisation on supply chains and services, the ageing workforce, the ageing of the society causing 
  the approach to care for elderly people as long as possible at their homes, and development in related

  OSH research extended its frame and objectives to**ethical considerations**, for example, regarding 
  research on corporate social responsibility or on working conditions in the supply chain.480 Moreover, 
  **environmental policies**influence safety and health at workplaces, for example, regarding the use of 
  safe but environmentally harmful chemicals, emissions from enterprises to air, soil and water, and 
  energy consumption.**Public health institutions**provide research results about the connection between 
  work and personal lifestyles, be it smoking or physical inactivity, adaptation of workplaces, and return 
  to work programmes in collaboration with**social security**or**professional**and**non-profit**
