Crossmark Policy
CrossMark is a multi-publisher initiative to provide a standard way for readers to locate the authoritative version of an article or other published content. By applying the CrossMark logo, The Busan, Ulsan, Gyeoungnam Branch of Korean Society of Otolaryngology-Head and Neck Surgery is committing to maintaining the content it publishes and to alerting readers to changes if and when they occur.
Clicking the CrossMark logo on a document will tell you its current status and may also give you additional publication-record information about the document.
