The text reviewed in this paper "Dongbangsaek is the Secret (Dongbangsaegi bigyeorira)" is in the collection of the Yulgok Memorial Library of Dankook University. With 13 leaves ($35.7{\times}22.3cm$) bound with thread, the booklet has been transcribed by hand. Although there is no record on the place, person and year of transcription, it is estimated to have been transcribed in the 20th century based on the use of the period, a punctuation mark. In addition, the complete absence of dialect vocabulary also shows that it was transcribed in the capital area-Seoul or Gyeonggi Province. It is assumed that the text is part of a Buddhist scripture chanted by an exorcist during a shamanistic ritual. As a booklet containing secret methods to divine what is auspicious and what is ominous in daily life, it must have been transcribed by an exorcist to use it for her ritual.

This study was performed to update the National Standard Food Composition Table (NSFCT) published by Korea Rural Development Administration, especially focusing on vitamin $B_{12}$ for Korean pork. Total 7 primal and 22 retail fresh cuts of Korean pork were analyzed for vitamin $B_{12}$ and the applied immunoaffinity-HPLC was validated. Vitamin $B_{12}$ assay by immunoaffinity-HPLC obtained recoveries over 95% and coefficient variations of precision below about 10%, which met the limits required for validation acceptance. Limits of detection and quantification of immunoaffinity-HPLC were 0.01 and $0.33{\mu}g/100g$, respectively. Quality control chart showed that analysis performance was excellent during the entire of study. Vitamin $B_{12}$ contents of pork cuts significantly varied depending the types of primal and its retail cuts (p<0.05). Belly, Boston butt, rib cuts showed relatively high vitamin $B_{12}$ contents compared to other primal cuts. Vitamin $B_{12}$ content of pork retail cuts were also significantly different within the same primal cuts (p<0.05). Among 22 retail cuts, the highest vitamin $B_{12}$ was observed in Tosisal in belly primal part ($0.98{\mu}g/100g$) while both Aldeungsimsal in loin and Hongdukkaesal in hide leg were the lowest by $0.33{\mu}g/100g$. This study provides reliable vitamin $B_{12}$ data for the Korean pork fresh cuts through standard sampling, method validation and analytical quality control, which would be used for update of Korean NSFCT.
