The main cyrillization system in use is the Kontsevich system (Russian: Систе́ма Конце́вича, romanized: Sistema Kontsevicha, IPA: [sʲɪˈsʲtʲemə kɐnˈt͡sɛvʲɪt͡ɕə]).
The Kontsevich system was created by the Soviet-Russian scholar Lev Kontsevich (Russian: Лев Конце́вич, IPA: [kɐnˈtsɛvʲɪtɕ]) in the 1950s based on the earlier transliteration system designed by Aleksandr Kholodovich [ru] (Russian: Алекса́ндр Холодо́вич, IPA: [ɐlʲɪkˈsandr xəlɐˈdovʲɪtɕ]).
Cyrillization systems for Korean were developed domestically in both North Korea (where it has been proposed to replace the current script in the past) and South Korea; Kontsevich carried out work on the systemization of these rules.
In contrast with some systems of Romanization of Korean, the transcription is based primarily on the pronunciation of a word, rather than on its spelling.
As a rule, syllables in given names are not separated.
