A national myth is an inspiring narrative or anecdote about a nation's past.
 Such myths often serve as an important national symbol and affirm a set of national values.
 A national myth may sometimes take the form of a national epic or be incorporated into a civil religion.
 A group of related myths about a nation may be referred to as the national mythos from μῦθος the original Greek word for "myth".
The sixth-generation Honda Civic was introduced in 1995 with 3-door hatchback, 4-door sedan and 2-door coupe body-styles, replicating its predecessor's line-up.
 A 5-door hatchback was also produced to replace the Honda Concerto hatchback in Europe but this model, while using the same design language as the rest of the Civic range, was quite distinct, instead being a hatchback version of the Honda Domani, sharing that car's platform which was related to the fifth-generation (EG/EH/EJ) Civic.
 The Domani replaced the sedan version of the Concerto in Japan while the sedan version of the Concerto was directly replaced by the sixth-generation Civic sedan in other markets.
 Two wagons were also made available; the JDM Orthia, based on the Civic sedan/3-door hatchback line, and a 5-door hatchback/Domani based model, sold as Civic Aerodeck, in Europe.
 Neither were offered in North America.
 The Civic 5-door hatchback also formed the basis for the 1995 Rover 400 although the 4-door sedan version of the Rover was quite distinct from the Domani.
In structuralism-influenced studies of mythology, a mytheme is a fundamental generic unit of narrative structure (typically involving a relationship between a character, an event, and a theme) from which myths are thought to be constructed - a minimal unit that is always found shared with other, related mythemes and reassembled in various ways ("bundled") or linked in more complicated relationships.
 For example, the myths of Adonis and Osiris share several elements, leading some scholars to conclude that they share a source, i.e. images passed down in cultures or from one to another, being ascribed new interpretations of the action depicted, as well as new names in various readings of icons. Claude Lévi-Strauss (1908-2009), who gave the term wide circulation, wrote, "If one wants to establish a parallel between structural linguistics and the structural analysis of myths, the correspondence is established, not between mytheme and word but between mytheme and phoneme."
The Munjeon Bonpuri (Korean: 문전본풀이 ) is meaning 'Annals of the Door', 'Book of the Door', 'Narration of the Door' or 'Explanation of the Door', is a myth of Jeju Island, explaining how many of the Gasin, or deities believed to reside within the house.
 It is one of the better-known myths of the Korean Peninsula.
Slaves of the Shinar is a historical fantasy novel that was written by Justin Allen and published in 2006.
 The book explores the early lives and origins of characters and peoples to be found in middle eastern myths and religious texts, especially the Biblical Book of Genesis and the Epic of Gilgamesh.
 Included from Genesis are depictions of the Nephilim (called Niphilim in the book), Jared (grandfather of Methuselah), Lamech (father of Noah) and Adah (wife of Lamech).
 The name Shinar also comes from the book of Genesis, chapter ten.
 Likewise, from the Epic of Gilgamesh and related middle-eastern myths come such figures as Gilgamesh, Enkidu and the gods Marduk, Baal, and Moloch.
The Cheonjiwang Bonpuri (Korean: 천지왕 본풀이 "Chronicles of Cheonjiwang") is a Korean creation myth, traditionally retold by shamans on the small island of Jejudo.
 It is one of the best-known creation myths in the Korean Peninsula and many key elements in the "Cheonjiwang Bonpuri" can be found in the creation myths of the mainland.
Agriculture is an important theme in Chinese mythology.
 There are many myths about the invention of agriculture that have been told or written about in China (Yang 2005:70).
 Chinese mythology refers to those myths found in the historical geographic area of China.
 This includes myths in Chinese and other languages, as transmitted by Han Chinese as well as other ethnic groups (of which fifty-six are officially recognized by current administration of China).
 (Yang 2005:4) Many of the myths about agriculture involve its invention by such deities or culture heroes such as Shennong, Houji, Hou Tu, and Shujun: of these Shennong is the most famous, according to Lihui Yang (2005:70).
 There are also many other myths.
 Myths related to agriculture include how humans learned the use of fire, cooking, animal husbandry and the use of draft animals, inventions of various agricultural tools and implements, the domestication of various species of plants such as ginger and radishes, the evaluation and uses of various types of soil, irrigation by digging wells, and the invention of farmers markets.
 Other myths include events which made agriculture possible by destroying an excessive number of suns in the sky or ending the Great Flood.
Korean mythology consists of national legends and folk-tales which come from all over the Korean Peninsula.
 The origin may be a blend of Korean shamanism, Buddhist, Chinese myths, Confucian and Taoist legends and myths.
 The legends may also vary greatly by region, even within the country.
 For example, the people of Jejudo have a very different lifestyle from that of the mainland and so can generate different forms of the same myths.
A pet door or pet flap (also referred to in more specific terms, such as cat flap, cat door, dog door, or doggie door) is a small portal in a wall, window or human door to allow pets to enter and exit a house (or other structure) on their own without needing a person to open the door.
 Originally simple holes, the modern form is a hinged and often spring-loaded panel or flexible flap, and some are electronically controlled.
 They offer a degree of protection against wind, rain, and larger-bodied intruders entering the dwelling.
 Similar hatches can let dogs through fences at stiles.
 A related concept is the pet gate, which is easy for humans to open but acts as a secure pet barrier, as well as the automated left- or right-handed pet doors.
A door is a moving mechanism used to block off, and allow access to, an entrance to or within an enclosed space, such as a building, room or vehicle.
 Doors normally consist of one or two solid panels, with or without windows, that swing on hinges horizontally.
 These hinges are attached to the door's edge but there are also doors that slide, fold or spin.
 The main purpose of a door is to control physical access.
