The World Health Organization (WHO) is a specialized United Nations agency which acts as a coordinator and researcher for public health around the world. Established on 7 April 1948, and headquartered in Geneva, Switzerland, the agency inherited the mandate and resources of its predecessor, the Health Organization, which had been an agency of the League of Nations. The WHO's constitution states that its mission "is the attainment by all peoples of the highest possible level of health." Its major task is to combat disease, especially key infectious diseases, and to promote the general health of the peoples of the world. Examples of its work include years of fighting smallpox. In 1979 the WHO declared that the disease had been eradicated - the first disease in history to be completely eliminated by deliberate human design. The WHO is nearing success in developing vaccines against malaria and schistosomiasis and aims to eradicate polio within the next few years. The organization has already endorsed the world's first official HIV/AIDS Toolkit for Zimbabwe from October 3, 2006, making it an international standard.
The WHO is financed by contributions from member states and from donors. In recent years the WHO's work has involved more collaboration, currently around 80 such partnerships, with NGOs and the pharmaceutical industry, as well as with foundations such as the Bill and Melinda Gates Foundation and the Rockefeller Foundation. Voluntary contributions to the WHO from national and local governments, foundations and NGOs, other UN organizations, and the private sector (including pharmaceutical companies), now exceed that of assessed contributions (dues) from its 193 member nations.

^{HOUSING :}

The English word house is derived from the proto-Germanic hud-dos, thought possibly to be a derivative of the verbal root hûd ‘to hide’ (see OED, s.v. house). Terms in other languages show varying derivations.
The oldest house in the world is approximately from 10,000 BC and was made of mammoth bones, found at Mezhirich near Kiev in Ukraine. It was probably covered with mammoth hides. The house was discovered in 1965 by a farmer digging a new basement six feet below the ground.
Architect Norbert Schoenauer, in his book 6,000 Years of Housing, identifies three major categories of types of housing: the "Pre-Urban" house, the "Oriental Urban" house, and the "Occidental Urban" house.
Types of Pre-Urban houses include temporary dwellings such as the Inuit igloo, semi-permanent dwellings such as the pueblo, and permanent dwellings such as the New England homestead.
"Oriental Urban" houses include houses of the ancient Greeks and Romans, and traditional urban houses in China, India, and Islamic cities.
"Occidental Urban" houses include medieval urban houses, the Renaissance town house, and the houses, tenements and apartments of the 19th and 20th centuries. Houses of that time were generally made of simple and raw materials (rocks, sticks, woven cloth, etc.

Expense

 In common usage, an expense or expenditure is an outflow of money to another person or group to pay for an item or service, or for a category of costs. For a tenant, rent is an expense. For students or parents, tuition is an expense. Buying food, clothing, furniture or an automobile is often referred to as an expense. An expense is a cost that is "paid" or "remitted", usually in exchange for something of value. Something that seems to cost a great deal is "expensive". Something that seems to cost little is "inexpensive". "Expenses of the table" are expenses of dining, refreshments, a feast, etc.
In accounting, expense has a very specific meaning. It is an outflow of cash or other valuable assets from a person or company to another person or company. This outflow of cash is generally one side of a trade for products or services that have equal or better current or future value to the buyer than to the seller. Technically, an expense is an event in which an asset is used up or a liability is incurred. In terms of the accounting equation, expenses reduce owners' equity. The International Accounting Standards Board defines expenses as  decreases in economic benefits during the accounting period in the form of outflows or depletions of assets or incurrences of liabilities that result in decreases in equity, other than those relating to distributions to equity participants.



In double-entry bookkeeping, expenses are recorded as a debit to an expense account (an income statementbalance sheet accounts. An expense decreases assets or increases liabilities. Typical business expenses include salaries, utilities, depreciation of capital assets, and interest expense for loans. The purchase of a capital asset such as a building or equipment is not an expense.

 Nutrition

     Nutrition (also called nourishment or aliment) is the provision, to cells and organisms, of the materials necessary (in the form of food) to support life. Many common health problems can be prevented or alleviated with a healthy diet.
The diet of an organism is what it eats, which is largely determined by the perceived palatability of foods.^{[citation needed]} Dietitians are health professionals who specialize in human nutrition, meal planning, economics, and preparation. They are trained to provide safe, evidence-based dietary advice and management to individuals (in health and disease), as well as to institutions.
A poor diet can have an injurious impact on health, causing deficiency diseases such as scurvy, beriberi, and kwashiorkor; health-threatening conditions like obesity and metabolic syndrome; and such common chronic systemic diseases as cardiovascular disease, diabetes, and osteoporosis.
