Veterinary support personnel in Japan do not currently hold any official state recognition and are known under a variety of equivalent names.
 Credentialing is carried out by various private organizations.
 These organizations are the Japan Animal Health Technicians Association (JAHTA), the Japanese Animal Hospital Association (JAHA), the Japan Small Animal Veterinary Association (JSAVA), the All Japan Veterinary Co-operative (JVC), and the Japanese Society of Animal Nursing.
 The Japanese Veterinary Nurses & Technicians Association (JVNTA), a non-certifying body which closed its doors in 2007, was one of the original member organizations of the IVNTA.
 In 2009 the Japanese Veterinary Nursing Association (JVNA) was organized as an effort to unify and standardize the profession in Japan and to seek state recognition.
 The JVNA, which has the support of the Japanese Veterinary Medical Association (JVMA—the national organization for veterinarians), may serve only as a temporary vehicle towards a single permanent national certifying body.
 All of the organizations have been collaborating since 2010 as the Council for Veterinary Nursing Examination and have reached an agreement to share a common examination in February 2012.
 In the meantime, a new organization, supported by the Ministry of Agriculture, Forestry, and Fisheries; the JVMA; and the JVNA has been tasked with developing a nationally sanctioned unified exam, the first of which was scheduled to be given in February 2013.
 Education lacks uniformity but in most cases consists of two- to three-year programs.
 A council of universities for animal nursing was also established and tasked with building a core curriculum for veterinary nursing.
 The council is made up of: Yamazaki Gakuen University, Nippon Veterinary and Life Science University, Kurashiki University of Science and the Arts, Teikyo University of Science, and Rakuno Gakuen University.
Rutebeuf (or Rustebuef) (fl.
 1245 – 1285), a trouvère, was born in the first half of the 13th century, possibly in Champagne (he describes conflicts in Troyes in 1249); he was evidently of humble birth, and he was a Parisian by education and residence.
 His name is nowhere mentioned by his contemporaries.
 He frequently plays in his verse on the word "Rutebeuf", which was a "nom de plume", and is variously explained by him as derived from "rude boeuf" and "rude oeuvre" ("coarse ox" or "rustic piece of work").
 Paulin Paris thought that he began life in the lowest rank of the minstrel profession as a "jongleur" (juggler and musician).
 Some of his poems have autobiographical value.
 In "Le Mariage de Rutebeuf" ("The Marriage of Rutebeuf") he says that on the 2 January 1261 he married a woman old and ugly, with neither dowry nor amiability.
 In the "Complainte de Rutebeuf" he details a series of misfortunes which have reduced him to abject destitution.
 In these circumstances he addresses himself to Alphonse, comte de Poitiers, brother of Louis IX, for relief.
 Other poems in the same vein reveal that his own miserable circumstances were chiefly due to a love of play, particularly a game played with dice; which was known as griesche.
 It would seem that his distress could not be due to lack of patrons; for his metrical "Life of Saint Elizabeth of Hungary" was written by request of Erard de Valery, who wished to present it to Isabel, queen of Navarre; and he wrote elegies on the deaths of Anceau de l'Isle Adam, the third of the name, who died about 1251, Eudes, comte de Nevers (died 1267), Theobald II of Navarre (died 1270), and Alphonse, comte de Poitiers (d. 1271), which were probably paid for by the families of the personages celebrated.
 In the "Pauvreté de Rutebeuf" ("The Poverty of Rutebeuf"), he addresses Louis IX himself.

Pravasam is a 2008 Malayalam novel written by M. Mukundan.
 According to the author, the novel is an attempt to re-define nostalgia which is thought to be the essence of life of non-resident Malayalis and to pay respect to hundreds of thousands of Malayalis living as non-resident Keralites in different parts of the world.
 It is a novel that travels through generations.
 It depicts a clear picture of the life stories of various persons living in various parts of the world as non-resident keralites.
 It explains us about the different kinds of feelings of various kinds of people who had left their homeland for various reasons.
 These reasons include the emigration for the sake of seeking a better profession, for studies, for getting a better class of living and so on.
 But almost all of them dreams of returning to their homeland one day and enjoying the homeliness.
 One of the issues the books addresses is the question of cultural identity of the Malayali.
 A notable fact about the novel is that renowned Malayalam author S. K. Pottekkatt is a major character in the narrative.
 In the beginning, the narration is given such that, story is told by Pottekkatt and after his death, it was completed by Mukundan.
 Even, the narrator, himself is a non-resident keralite and has a lot of experiences to share with the readers.
 Whatever amenities the emigration life had provided them, each one of them, deep in their mind had a strong desire to come back to their native land one day.
 This uncontrolled emotions and sentiments of malayalis towards their homeland is clearly illustrated in the story.
