Question: What film type has been around since the early years of Korean cinema and includes Whispering Cooridors as an example?
Context: Kang Woo-suk (b. November 10, 1960 in Gyeongsan) is a South Korean film producer and director.  He has often been called the most powerful man in Korean cinema, topping Cine21 magazine's list of '50 Most Powerful Men in Korean Cinema' for seven consecutive years from 1998 to 2004. The classification is based on similarities at the tertiary and primary structural levels.  Comparisons are restricted to that part of the sequence directly involved in the reaction, which in the case of a peptidase must include the active site, and for a protein inhibitor the reactive site.  The classification is hierarchical: sequences are assembled into families, and families are assembled into clans.  A family is assembled around a "type example", the sequence of a well-characterized peptidase or inhibitor.  All other sequences in the family must be related to the family type example, either directly or through a transitive relationship involving one or more sequences already shown to be family members.  Typically, FastA or BlastP are used to establish sequence relationships, with an expect value of 0.001 or lower taken to be statistically significant.  A clan is also assembled around a type example, this being the structure of a well-characterized peptidase or inhibitor.  A family is included in a clan if the tertiary structure of a family member can be shown to be related to that of the clan type example.  Typically, DALI is used to establish clan membership, with a z score of 6.00 standard deviation units or above considered to be statistically significant.  For peptidases, other evidence to indicate that families are related when a tertiary structure is absent includes the same order of catalytic residues in the sequences. The race film or race movie was a film type produced entirely in the United States between about 1915 and the early 1950s, consisting of films produced for an all-black audience, featuring black casts. Nation and Destiny (Chosŏn'gŭl: 민족과 운명 ; MR: "Minjokgwa ummyeong " ) is a 62-part North Korean film series released between 1992 and 2002.  It aims to show that the Korean people "can live a glorious life only in the bosom of the Great Leader and socialist fatherland".  Kim Jong-Il personally chose the title and was extensively involved in the early episodes.  Conceived as the largest film series ever produced in any country, it was the largest investment ever made in the history of North Korean cinema.  Initially, the most senior writers, directors and actors were involved in the project and it was heavily promoted and eulogized by the North Korean media.  The series was projected to reach 100 episodes, but none have been released since 2002. The term "Cinema of Korea" (or "Korean cinema") encompasses the motion picture industries of North and South Korea.  As with all aspects of Korean life during the past century, the film industry has often been at the mercy of political events, from the late Joseon dynasty to the Korean War to domestic governmental interference.  While both countries have relatively robust film industries today, only South Korean films have achieved wide international acclaim.  North Korean films tend to portray their communist or revolutionary themes. Whispering Corridors (; also known as Ghost School and Ghost School Horror) is a South Korean horror film series.  The series uses an all-girls high school as the backdrop for each of its films and doesn't share a continuing plot.  Every "Whispering Corridors" film features a different plot, characters and settings.  The series is notable for helping generate the explosion of the New Korean Wave cinematic movement, and dealing with taboo topics such as authoritarianism in the harsh South Korean education system, gay relationships and teen suicide, following the liberalization of censorship. Korean horror films have been around since the early years of Korean cinema, however, it was not until the late 1990s that the genre began to experience a renewal.  Many of the Korean horror films tend to focus on the suffering and the anguish of characters rather than focus on the explicit "blood and guts" aspect of horror.  Korean horror features many of the same motifs, themes, and imagery as Japanese horror. Whispering Corridors () is a 1998 South Korean horror film.  It was part of the explosion in Korean cinema following the liberalization of censorship in the aftermath of the end of the country's military dictatorship, and makes a strong social commentary on authoritarianism and conformity in the harsh South Korean education system. Because of the isolated nature of the country, information—particularly unbiased information—on North Korean cinema is difficult to find.  Outsider appraisal of North Korean cinema is often condescending, while statements from official North Korean sources include claims like, "In recent years our film art has created an unprecedented sensation in the world's filmdom... The revolutionary people of the world are unstinting in their praise of this feature film and other monumental works, calling them 'the first-class films by international standards', 'the most wonderful movies ever produced' and 'immortal revolutionary and popular films'." 9th New York Korean Film Festival was held by the Korea Society showcasing a selection of the best of contemporary Korean cinema.  The 2010 New York Korean Film Festival featured eight films in a collaborative effort with the Museum of Modern Art (MoMA) and the Brooklyn Academy of Music (BAM) Rose Cinema.  Like previous festivals, the 2010 New York Korean Film Festival screened contemporary Korean films and also featured panel discussions with directors and other icons of Korean Cinema.  The festival lasted from September 22, 2010 to October 3, 2010.  Ranging from action to comedy, sci-fi to horror, to genre-bending altogether, this year's films represented not only Korea's top box-office hits but also some of the industry's most creative and substantial movies to date.
