Medical and health undertakings:
The medical and health undertakings of a country include all the people, organizations, systems, rules and processes in the country to protect and improve people's health and treat diseases and injuries.
Medical care has five main purposes: openness to all, quality, effectiveness, economy and satisfaction of patients and staff.
The biggest influence of national politics on a country's medical and health care is to stipulate its financial system. The health care financial system in the countries of the Organization for Economic Cooperation and Development can be divided into three categories:
National economy: medical and health care (such as Britain and Italy) social insurance established through taxation; private insurance established through legal medical insurance (such as Germany and France); individual or enterprise insurance (such as the United States). Generally, a country has a variety of economic models mixed. In many countries, the proportion of public expenditure on health care has increased.

Electricity:
Electricity is an energy source driven by electric energy. 19 The invention and application of electric power in the 1970s set off the second climax of industrialization. It has become one of the three major scientific and technological revolutions in the world since the18th century in human history, and technology has changed people's lives since then.
The large-scale power system that appeared in the 20th century is one of the most important achievements in the history of human engineering science. It is a power production and consumption system composed of power generation, transmission, substation, distribution and electricity consumption. It converts the primary energy in nature into electric energy through power generation devices, and then supplies the electric energy to all users through transmission, transformation and distribution.
Telecommunications:
