FT-IR, GC/MS, and ATR-FT-IR analyses were performed to confirm the physicochemical characteristics of saw palmetto fruit (SPF) extract. FT-IR analysis of the standard product showed that the band corresponding to the carbonyl bond of free fatty acid was stronger than the band of acyl-glyceride. Sample E was identified as having the same trend as the standard sample. Fatty acid composition analysis revealed that the main fatty acids in the standard sample were lauric acid and oleic acid. The content of lauric acid ranged from approximately 30% to 38% in samples B, C, D, and E, while the content of oleic acid ranged from approximately 29% to 34%. The GC/MS analysis confirmed that the standard SPF extract consisted of fatty acids and fatty acid ethyl esters. Sample E demonstrated a similar pattern to the standard samples in terms of oleic acid, lauric acid, and fatty acid esters. ATR-FT-IR analysis indicated that only sample E was predicted to contain 100% saw palmetto extract. Therefore, these study findings can be considered fundamental data for analyzing the physicochemical characteristics of the composition of SPF extract.

Tariff reduction from FTAs are applied to imported goods, but not to traveler's goods. There are difficulties in meeting the FTA's conditions for free tariff application, such as origin of goods and direct transportation. This study suggests the optimal cut-off level of a simple tax rate applied to traveler's goods with respect to traveler' welfare and government tax revenue. Among three different scenarios of simple tax reductions by ordering its weighted magnitude of effects, the optimal tariff was found to be 2% applied to all goods. The effects of a 2% reduction of simple tax rate would increase traveler' welfare by 16.8 billion won and reduce tax revenue by only 0.34 billion won.
