Currently, most of content restoration using artificial intelligence learning is 2D learning. However, 3D form of artificial intelligence learning is in an incomplete state due to the disadvantage of requiring a lot of computation and learning speed from the existing 2 axes (X, Y) to 3 axes (X, Y, Z). The purpose of this paper is to secure a data-set for artificial intelligence learning by analyzing and 3D modeling the stone pagodas of ourinari by era based on the two-dimensional information (image) of cultural assets. In addition, we analyzed the differences and characteristics of towers in each era in Korea, and proposed a feature modeling method suitable for artificial intelligence learning. Restoration of cultural properties relies on a variety of materials, expert techniques and historical archives. By recording and managing the information necessary for the restoration of cultural properties through this study, it is expected that it will be used as an important documentary heritage for restoring and maintaining Korean traditional pagodas in the future.

There are many definitions around brand. It complexify academic literature. Thus, this study collected meaningful definitions among many statements about brand and analyzed and classified them by available perspectives. This is especially necessary contents in domestic brand study, which is short of concept research about brand. Various literatures are refereed to brand definition introduction. But to etymological definition, several European linguistic theses are deeply reviewed and to institutional definition, wide range of information such as history, law and society is refereed. Total brand definitions are classified in . It is divided into 2 parts which are non-commercial context (etymological and institutional definition) and commercial context (producer, customer and the relation or interaction between producer and customer). In etymological definition, the word origin is clear word 'brandr' which means 'burning wood' and cattle-brand made this 'brand'. In legal definition, legal and institutional meaning of 'trademark' is examined. Etymological definition and institutional definition are fundamental and lexical definition which show brand history. These are foundation stones in brand studies.

With the development of ICT technologies, various systems and services based on data have been introduced. Also, raising the importance of technologies that provide trust to a data, infrastructure, and services. for ICT services. However, in the existing ICT service environment, there is no way to objectively judge and manage the trust of various components (content, infrastructure, process, service provider, etc) that constitute a specific service, and there is a limitation that we can only rely on the service provider's own quality standards. This paper provides requirements, functional archtecture, and procedures for providing reliable ICT services from the perspective of ITU-T international standards. Trust-enabled service provisioning adds additional functions for providing trust to existing ICT service entities (service resources, stakeholders, and users), collecting, analyzing, and providing trust related information. Therefore, a users can consider the trust of various service components based on analyzed trust information based on their trust requirements.

With the increasing demand for and utilization of large language models (LLMs), the risk of user sensitive information being inputted and leaked during the use of LLMs also escalates. Typically recognized as a tool for mitigating the hallucination issues of LLMs, knowledge graphs, constructed independently from LLMs, can store and manage sensitive user information separately, thereby minimizing the potential for data breaches. This study, therefore, presents a knowledge graph-based chatbot that transforms user-inputted natural language questions into queries appropriate for the knowledge graph using LLMs, subsequently executing these queries and extracting the results. Furthermore, to evaluate the functional validity of the developed knowledge graph-based chatbot, performance tests are conducted to assess the comprehension and adaptability to existing knowledge graphs, the capability to create new entity classes, and the accessibility of LLMs to the knowledge graph content.
