All of the languages in the cultural and linguistic Sinosphere display the phenomenon of borrowing Han characters and Han radicals to form their own scripts. The Nom Viet is no exception. When studying the structure of Nom Viet, scholars often use Han characters as the basis to analyze the structure of the Nom characters and divide them into different categories. This approach is applicable to the vast majority of Nom characters. However, in practice, when studying the processes of creating and using characters through many Nom texts, it is found that some Nom characters are formed on the basis of pre-existing Nom characters. This category of Nom characters, for a long time, has not won the attention of scholars. Surveying over 50 different Nom works, this article has collected 25 Nom characters with a multi-layered structure, which we call the derivative Nom category. By analyzing the components that directly make up these Nom characters and relying upon new research results on Chinese grammatology, the article will analyze and specify the internal structure of these Nom characters. The article has classified and presented the model of these Nom scripts. In addition, the separation of elements directly forming the characters has shown the process of acculturation of Chinese characters in Vietnam. It can be seen that the number of Nom derivatives is not large. However, their presence has more or less provided new materials for studying the structure of the Nom characters. Hopefully, the analysis in this article will contribute to shedding light on the current theoretical issues regarding the structure of the Nom Viet.

본 논문은 다중 적층지반상의 지반-구조물 상호작용 해석을 위한 3차원 무한요소를 소개한다. 본 무한요소는 Cartesian 좌표계에서 정식화되었으며, 수평, 수평모서리, 수직, 수직 모서리 그리고 수평 수직 모서리 무한요소로서 총 5개의 무한요소로서 구성된다 적용한 형상함수 내부의 파동함수들은 적층지반의 파동문제를 효과적으로 모사하며 다중파동성분을 포함하고 있다. 본 요소의 성능을 검증하기 위하여 주파수영역에서 여러 가지 예제해석을 수행하였다. 균질 및 적층지반상 강체기초와 묻힌 케이슨 기초의 무차원 동적 거동(compliance & impedance)을 구하였으며, 기연구자들의 값과 비교 검토하였다.

Unconditional usage of multi-layered waterproofing membrane system is common in large scale spatial structures in the contemporary setting. This study aims to evaluate the limitation of multi-layered waterproofing membrane system applied to the roofing system of large scale spatial structure and examine thoroughly whether such systems are suitable for steel plate concrete or not.
