Spot Test (lichen)
A spot test in lichenology is a spot analysis used to help identify lichens. It is performed by placing a drop of a chemical reagent on different parts of the lichen and noting the colour change (or lack thereof) associated with application of the chemical. The tests are routinely encountered in dichotomous keys for lichen species, and they take advantage of the wide array of lichen products (secondary metabolites) produced by lichens and their uniqueness among taxa. As such, spot tests reveal the presence or absence of chemicals in various parts of a lichen. They were first proposed as a method to help identify species by the Finnish lichenologist William Nylander in 1866. Three common spot tests use either 10% aqueous KOH solution (K test), saturated aqueous solution of bleaching powder or calcium hypochlorite (C test), or 5% alcoholic ''p''-phenylenediamine solution (P test). The colour changes occur due to presence of particular secondary metabolites in the lichen. In ide ...

Kaon
In particle physics, a kaon, also called a K meson and denoted , is any of a group of four mesons distinguished by a quantum number called strangeness. In the quark model they are understood to be bound states of a strange quark (or antiquark) and an up or down antiquark (or quark). Kaons have proved to be a copious source of information on the nature of fundamental interactions since their discovery by George Rochester and Clifford Butler at the Department of Physics and Astronomy, University of Manchester in cosmic rays in 1947. They were essential in establishing the foundations of the Standard Model of particle physics, such as the quark model of hadrons and the theory of quark mixing (the latter was acknowledged by a Nobel Prize in Physics in 2008). Kaons have played a distinguished role in our understanding of fundamental conservation laws: CP violation, a phenomenon generating the observed matter–antimatter asymmetry of the universe, was discovered in the kaon ...

Korean Wave
The Korean Wave, or ''hallyu'' (; ), is a cultural phenomenon in which the global popularity of South Korean popular culture has dramatically risen since the 1990s. Worldwide interest in Korean culture has been led primarily by the spread of K-pop, Korean drama, K-dramas, and Cinema of South Korea, films, with keystone successes including K-pop groups BTS and Blackpink, the Academy Awards, Oscar-winning film ''Parasite (2019 film), Parasite'' (2019), and the television series ''Squid Game'' (2021). The Korean Wave has been recognized as a form of soft power and as an important economic asset for South Korea, generating revenue through both exports and tourism. Following the 1997 Asian financial crisis and the end of military censorship over the South Korean entertainment industry, the country emerged as a major exporter of popular culture. The Korean Wave was first driven by the spread of K-dramas and Korean cinema into East Asia and parts of Southeast Asia, following the rise o ...

K-pop
K-pop (; an abbreviation of "Korean popular music") is a form of popular music originating in South Korea. It emerged in the 1990s as a form of youth subculture, with Korean musicians taking influence from Western Electronic dance music, dance music, hip-hop, Contemporary R&B, R&B and Rock music, rock. Today, K-pop commonly refers to the musical output of teen idol acts, chiefly girl groups and boy bands, who emphasize Visual communication, visual appeal and Performing arts, performance. As a Pop music, pop genre, K-pop is characterized by its Melody, melodic quality and cultural hybridity. K-pop can trace its origins to "rap dance", a fusion of hip-hop, techno and rock popularized by the group Seo Taiji and Boys, whose experimentation helped to modernize South Korea's contemporary music scene in the early 1990s. Their popularity with teenagers incentivized the music industry to focus on this demographic, with Lee Soo-man of SM Entertainment developing the Korean idol system i ...

K-drama
Korean drama (), also known as K-drama or Koreanovela, refers to Korean-language television shows made in South Korea. These shows began to be produced around the early 1960s, but were mostly consumed domestically until the rise of the Korean Wave in the 1990s. They have since achieved significant international popularity, with millions of viewers across the world. Beginning around the 1970s, more and more households in South Korea owned televisions. Programs were often produced on low budgets and were mostly consumed domestically. The industry significantly developed in the 1980s, after the spread of color television. Beginning in the early 1990s, several Korean dramas began achieving significant international popularity, primarily in China and Japan. In addition, South Korean popular music ("K-pop") and films began seeing similar successes, which gave rise to rapid international adoption of South Korean media in a phenomenon commonly called the Korean Wave. In the following dec ...
