In the original publication of this article, the incorrect citation was given for the quotation in the second sentence of the first full paragraph on p. 92. The citation at the end of this sentence should be (Kim Subŏm Reference Kief1966, 57).
Additionally, the author would like to clarify that the preceding citation “(56),” on the last line of p. 91, refers to (Kim Subŏm Reference Kief1966, 56).
The publisher apologizes for this error.
