Square (sailing)

The term to square a yard is used when sailing a square-rigged ship.

To "square a yard" is to lay the yards at right angles to the line of the keel by trimming with the braces.

Explanation

"Squaring a yard" adjusts the position of the square sails so that they are perpendicular to the keel of the ship. This is done in order to "run before the wind', i.e., sail with the wind directly behind the vessel rather than tacking.

When a square-rigger is running downwind, and the yards are positioned perpendicular to the line of the keel, both sheets that control the yard (braces) are tied off aft (i.e., straight back), leading to the figurative phrase "Both sheets aft."

"Both sheets aft, The situation of a square-rigged ship that sails before the wind, or with the wind right astern. It is said also of a half-drunken sailor rolling along with his hands in his pockets and elbows square."

Further definition

"Square ... A term peculiarly appropriated to the yards and their sails. Thus, when the yards hang at right angles with the mast they are said to be 'square by the lifts;' when perpendicular to the ship's length, they are 'square by the braces;' but when they lie in a direction perpendicular to the plane of the keel, they arc 'square by the lifts and braces.' The yards are said to be very square when they are of extraordinary length, and the same epithet is applied to their sails with respect to their breadth."

Square (cipher)

In cryptography, Square (sometimes written SQUARE) is a block cipher invented by Joan Daemen and Vincent Rijmen. The design, published in 1997, is a forerunner to Rijndael, which has been adopted as the Advanced Encryption Standard. Square was introduced together with a new form of cryptanalysis discovered by Lars Knudsen, called the "Square attack".

The structure of Square is a substitution-permutation network with eight rounds, operating on 128-bit blocks and using a 128-bit key.

Square is not patented.

Dogū

Dogū (土偶)(meaning "clay figures") are small humanoid and animal figurines made during the late Jōmon period (14,000–400 BC) of prehistoric Japan. Dogū come exclusively from the Jōmon period. By the Yayoi period, which followed the Jōmon period, Dogū were no longer made. There are various styles of Dogū, depending on exhumation area and time period. According to the National Museum of Japanese History, the total number found throughout Japan is approximately 15,000. Dogū were made across all of Japan, except Okinawa. Most of the Dogū have been found in eastern Japan and it is rare to find one in western Japan. The purpose of the Dogū remains unknown and should not be confused with the clay haniwa funerary objects of the Kofun period (250 – 538).

Origins

Some scholars theorize the Dogū acted as effigies of people, that manifested some kind of sympathetic magic. For example, it may have been believed that illnesses could be transferred into the Dogū, then destroyed, clearing the illness, or any other misfortune.

Dog in Chinese mythology

Dogs are an important motif in Chinese mythology. These motifs include a particular dog which accompanies a hero, the dog as one of the twelve totem creatures for which years are named, a dog giving first provision of grain which allowed current agriculture, and claims of having a magical dog as an original ancestor in the case of certain ethnic groups.

Myth versus history

Chinese mythology is those myths found in the geographic area called China, which of course has evolved and changed throughout its history. These include 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 the current administration of China). (Yang 2005:4)

In the study of historical Chinese culture, many of the stories that have been told regarding characters and events which have been written or told of the distant past have a double tradition: one which tradition which presents a more historicized and one which presents a more mythological version.(Yang 2005: 12-13) This is also true of some accounts related to mythological dogs in China.

Dog meat

Dog meat refers to the flesh and other edible parts derived from dogs. Historically, human consumption of dog meat has been recorded in many parts of the world, including East and Southeast Asia, West Africa, Europe, Oceania and the Americas.

In the 21st century, dog meat is consumed in many parts of China,Korea and Vietnam, parts of Switzerland, as well as parts of Europe, Americas, the African continent, such as Cameroon, Ghana and Liberia.

Today, a number of cultures view the consumption of dog meat to be a part of their traditional and day-to-day cuisine, while others - such as Western culture - consider consumption of dog to be a taboo, although they have been consumed in times of war and/or other hardships. It was estimated in 2014 that worldwide, 25 million dogs are eaten each year by humans.

Dog breeds used for meat

Nureongi

The Nureongi (Korean: 누렁이) is a yellowish landrace from Korea. Similar to other native Korean dog breeds, such as the Jindo, nureongi are medium-sized spitz-type dogs, but are larger with greater musculature and a distinctive coat pattern. They are quite uniform in appearance, yellow hair and melanistic masks. Nureongi are most often used as a livestock dog, raised for its meat, and not commonly kept as pets.
