  • 이 연구는 고대 무경칠서 가운데 하나로 군사학 이론서로서인 삼략의 판본을 조사하여 판본에 대한 개괄적인 분석과 판본의 선후 문제 및 계통을 세우고자 하였다. 또한 아직까지 알려지지 않았던 새로운 판본과 언해본의 소개를 통하여 서지학 및 국어학 관련분야의 연구에 보탬이 되고자 하였다.

  • For enhancing the flame-retardant properties of wallpapers, we developed an organic-inorganic hybrid solution with ZrSiO4 as a functional ceramic powder, coated on non-woven fabric using dip coating, spray coating, and slot-die coating methods. Their flame retardant properties were characterized by a 45° combustion tester, which is manufactured according to the flame-retardant performance standard (KOFEIS 1001 and KS F 2819). In organic-inorganic hybrid solution, with increasing the concentration of acid-catalyst (acetic acid), the precipitation of ZrSiO4 powders increased, and the flame retardant properties decreased. The highest flame retardant result was obtained for the solution adding 5 wt% acetic acid. The optimization of the coating method and coating number resulted in the most excellent flame-retardant properties being obtained for the non-woven fabric coated for 5 or 7 times by dip coating method, and their flame-retardant properties corresponded to class 2 flame-retardant performance of wallpapers.
