In this study, 70 kinds of nutritional composition for five bokkeumbap products(spicy chicken, shrimp(saeu), haemul, nakji, and barbecue bokkeumbap) in high-frequency processed foods were analyzed. Raw data of intake amounts were collected from the 7th Korea National Health and Nutrition Examination Survey. Regarding proximate composition, spicy chicken bokkeumbap had lower water content and higher carbohydrate content than other bokkeumbaps, resulting in the highest total calories. The proximate composition of other bokkeumbaps were all distributed within a similar range. Vitamin content differed according to ingredients added to the bokkeumbaps. Haemul bokkeumbap had high content of vitamins B<sub>1</sub> and B<sub>2</sub>, nakji bokkeumbap had high content of vitamin C and β-carotene, and barbecue bokkeumbap had high content of total niacin, folic acid, and vitamin A. For mineral content, barbecue bokkeumbap showed the highest content distribution, while nakji bokkeumbap showed the lowest content distribution. Regarding fatty acid and fat content, the highest content of fatty acids, saturated fats, and trans fats was detected in shrimp(saeu) bokkeumbap. For amino acid content, barbecue bokkeumbap showed highest content distribution. These results can be used as salient basic data for a food nutrient composition database and to significantly contribute to consumers' health.

Despite the excellent mechanical properties, practical application of bulk metallic glasses (BMGs) is limited due to difficulties in fabricating bulk products from BMG. Alternatively, BMGs are deposited as thin film on substrates i.e. thin-film metallic glass (TFMG) for utilizing their mechanical performances. As tensile or compression testing at nanoscale is infeasible for mechanical characterization, we use nanoindentation tests to investigate the nanomechanical behavior of Zr-TFMG deposited on various substrates. The deformation behaviors of Zr-TFMG and mechanical properties are then analyzed through finite element (FE) simulations. The effects of peak and cyclic loads and loading rate on the nanomechanical properties are investigated. Observation of significant pile-up of TFMG on Si substrate demonstrates that the deformation behavior of Zr-TFMG is affected by substrate material. Finally, based on the experimental and numerical nanoindentation studies, the nanomechanical properties of Zr-TFMG were evaluated.
