The Colectiv nightclub fire was a deadly fire in Bucharest, Romania, on 30 October 2015, which killed 64 people (26 on site, 38 in hospitals) and injured 147.
 The fire, the worst incident in Romania since the Balotești plane crash, occurred during a free concert performed by the metalcore band Goodbye to Gravity to celebrate the release of their new album, "Mantras of War".
 The band's pyrotechnics, consisting of sparkler firework candles, ignited the club's flammable polyurethane acoustic foam, and the fire spread rapidly.

 Mass protests over the corruption linked to the fire led to the resignation of the Prime Minister of Romania, Victor Ponta.

Hagwon (] ) is the Korean-language word for a for-profit private institute, academy or cram school prevalent in South Korea.
 Although most widely known for their role as "cram schools", where children can study to improve scores, hagwon actually perform several educational functions: they provide supplementary education that many children need just to keep up with the regular school curriculum, remedial education for the children who fall behind in their work, training in areas not covered in schools, and preparation for students striving to improve test scores and preparing for the high school and university entrance examinations (the university entrance exam is also called suneung (수능)).
 Many other children, particularly younger children, attend nonacademic hagwon for piano lessons, art instruction, swimming, and taekwondo (태권도).
 Most young children attend a hagwon.
 Hagwon also play a social role, and many children, especially the younger ones, say they like going to hagwon because they are able to make new friends; many children ask to be sent because their friends attend.
 There are many hagwon for adults too, such as flower arrangement and driving-license hagwon.
 The term is also sometimes used to describe similar institutions operated by Korean Americans in the United States.
