  • This study is about the new examining of the books' period for publication, system, and the relationship with the original script by considering the books of 'Sambon Hwayemgyeong of Suchangpan series' as a whole. As a result, the books of 'Sambon Hwayemgyeong of Suchangpan series' are arranged with four types, '11th century edition'(estimated the first published book), 'Suchangsanyun edition(1098) and Sookjongyeongan edition(1096-1105)', '12th to 13th century edition', and 'Haeinsa Sagan edition(12th-13th century)'. Among them, especially '11th century edition'(estimated the first published book) is the book that has been known as a 'Y$\ddot{u}$an book', '12th century edition' or 'bokgakbon of the Kitan(or Seoha) line's book', and 'Sookjongyeongan edition (1096-1105)' and so on.

  • With the aim of using a filler material in a conductive paste, fine Cu nanoparticles were synthesized through the high-speed chemical reaction between cuprous oxide ($Cu_2O$) powder and sulfuric acid in distilled water. Under external temperature of $7^{\circ}C$, sulfuric acid concentration of 48%, and $Cu_2O$ amount of 30 g, the $Cu_2O$ particles were eliminated and slightly aggregated Cu nanoparticles were synthesized. Futhermore, Cu nanoparticles of 224 nm, in which the aggregation between particles was obviousiy much suppressed, were synthesized with the choice of an additive. In the particle sample, occasionally there are coarse particles formed by the aggregation of fine nanoparticles and weak linkages between the nanoparticles. However, the coarse particles were destroyed and the linkages were broken after mixing with a resin formulation, indicating the behavior of untangling the aggregation between nanoparticles.
