Metric Options: CountsSelecting the 1-year or 3-year option will change the metrics count to percentiles, illustrating how an article or review compares to other articles or reviews within the selected time period in the same journal. Selecting the 1-year option compares the metrics against other articles/reviews that were also published in the same calendar year. Selecting the 3-year option compares the metrics against other articles/reviews that were also published in the same calendar year plus the two years prior.
Example: if you select the 1-year option for an article published in 2019 and a metric category shows 90%, that means that the article or review is performing better than 90% of the other articles/reviews published in that journal in 2019. If you select the 3-year option for the same article published in 2019 and the metric category shows 90%, that means that the article or review is performing better than 90% of the other articles/reviews published in that journal in 2019, 2018 and 2017.

Article Description
This study was conducted to investigate the effects of gas grafting treatment on the durability of Korean traditional paper i.e., Hanji. Dry heating- and humid heating-accelerated aging tests were performed. Further, the properties of each Hanji sample, including strength, optical property, Cobb size degree, and static contact angle, were analyzed. The decrease in the strength and optical characteristics of the Hanji hydrophobized via gas grafting with palmitoyl chloride during artificial aging was found to be more significant than that of untreated paper. The decrease in durability was speculated to be caused by the residual free fatty acids in the Hanji. In contrast, no changes in the Cobb size and static contact angle of the hydrophobic Hanji occurred during accelerated aging. In summary, the hydrophobicity of Hanji grafted with palmitoyl chloride remained unchanged during 30 days of dry-heating aging and 60 days of humid-heating aging, however, the durability of paper material, including strength and optical properties, deteriorated. Therefore, the attenuation and elimination of residual free fatty acids must be investigated to prevent the decrease of durability.
