콘텐츠 관리 시스템(CMS:Contents Management System)은 '자료 수집, 등록, 검색, 배포'의 기본 흐름을 가진다. 콘텐츠의 등록 및 검색/배포를 위하여 각 시스템은 콘텐츠에 대한 별도의 메타 파일들을 가지고 있으나, 이러한 메타파일들은 데이터 요소의 중의성이나 모호함 때문에 일관되고 객관화 된 스키마를 가지지 못하여 체계적 분류 및 최신 업데이트를 위한 메타데이터 자체의 효율적 관리 및 연관 검색 기능을 가지고 있지 않았다. 본 논문에서는 기존 연구되고 있는 MDR과 토픽맵을 자체 개발 중인 콘텐츠 메타파일 관리 시스템(CMMS:Contents Metafile Management System)에 적용하여 메타파일의 체계적이고 효율적인 관리를 통해 기준요소로서의 메타파일 역할을 극대화하고 향후 타 체계와의 연동 및 확장성의 향상을 도모한다.

The new environment for records managements requires the revolutionary transition from paper-record management to electric-record management. Capturing contents, contexts, and structure informations of the electric records to preserve the evidentiality, authenticity, and reliability is the outstanding issue. The recordkeeping metadata has been placed at the center of the current issue. This study focused on the establishment of the structures of recordkeeping metadata for current and semi-current stages in the life cycle of records. The reason concentrated on current and semi-current stages is that the authenticity of the record is concerned as the evidence of the business processes. Current and semi-current stages are where the records is able to be produced, captured and managed in the business context. The metadata can be collected and preserved with authenticity. This study explained the relations between entities concerned with producing records and proposed the metadata elements by establishing data model.

Business stakeholders have shown huge interests on the way how to increase business value by integrating real world businesses with a rising metaverse concept. To understanding the utility of metaverse regarding digital transformation, this study conducted a qualitative study based on a metaverse framework from 2006 Metaverse Roadmap and reference theories on business models. Specifically, a multiple comparative case approach was adopted to investigate three metaverse application cases from 2000 to 2020. From findings, it was revealed that different metaverse features were tried to leverage traditional simulation games, social communities, and virtual communication activities to build business models. Secondly, the use of metaverse features were likely to be helpful in getting competitive advantages. However, we are also aware that stakeholder credibility should be carefully managed to sustain businesses.

다양한 온톨로지들이 구축되고 이를 적용한 시스템들이 늘어가면서 시스템 간 상호운용성에 문제가 발생하게 되었다. 이러한 문제점을 해결하기 위해 공통 개념이라 볼 수 있는 온톨로지를 메타데이터 레지스트리에 등록하고, 이를 기반으로 한 시스템들이 개발되면서 시스템 간 상호운용성이 향상되었다. 하지만 서로 다른 메타데이터 레지스트리를 기반으로 한 시스템 간에는 상호운용성 문제가 여전히 존재하므로, 메타데이터 레지스트리에 등록된 온톨로지 간 매칭 방법에 대한 필요성이 대두되었다. 기존의 온톨로지 매칭 방법들은 온톨로지의 규모가 작을 경우 정확한 매칭 결과를 제공하지 못하는 문제점을 가진다. 따라서 이 논문에서는 메타데이터에 레지스트리에 등록된 온톨로지들을 매칭하기 위하여 메타데이터 레지스트리의 구조상의 특징을 반영하여 온톨로지를 확장한다. 그리고 확장된 온톨로지를 이용하여 온톨로지를 매칭 함으로써 정확한 매칭이 이루어지는 온톨로지 매칭 방법을 제안한다. 또한 제안 방법의 장점을 보이기 위해 기존 온톨로지 매칭 방법들과의 비교평가를 수행한다. 제안 방법은 매칭의 정확성을 보장하고 효율성을 높이며 메타데이터 레지스트리간 상호운용성을 높인다.

Currently, for teenagers, the metaverse is becoming an important space for communication and experience. Due to the development of AI technology, experiences in the metaverse space are diversifying, which means that experiences in the virtual world can affect the real self. Therefore, this study attempted to examine the necessity of establishing a new concept of empathy across the metaverse for the AI era. In accordance with literature studies related to empathy, one was confirmed that the concept of empathy has been changing according to social ideas in times. In addition, with the result of the analysis of recent research trends, it was considered that the current study of empathy is generally taking a view as a measure of 'upright sociality.' In the end, this study suggest the necessity of redefined empathy in order to cultivate upright sociality in the metaverse.

The purpose of this study was to verify the effectiveness of the employee metacognition and it's positive effect on employee agility. Also it aims to investigate the mechanism through the cascading multi-mediating effect through the role breadth self-efficacy and learning agility in such a relationship. In order to solve the common-method bias, independent and dependent variables were measured with time lag, and the relationship between variables was clearly verified by applying the position and the length of time worked with the supervisor as control variables. In testing the hypothesis, 478 questionnaires collected from whom worked at the company has more than 300 office workers in various industries were analyzed. As the result, firstly metacognition had a significant positive(+) effect on employee agility. Second, role breadth self-efficacy was found to positively mediate the relationship between metacognition and employee agility. Third, learning agility was found to mediate metacognition and employee agility positively(+). Fourth, metacognition serially mediates role breadth self-efficacy and learning agility, and the positive(+) effect on employee agility was verified. In addition, metacognition had a greater effect on member agility when passing through role breadth self-efficacy and learning agility rather than the direct effect on employee agility.

Metadata is a general notion of data about data to improve data sharing and exchanging by definitely describing meaning and representation of data. However, metadata has been created in various ways and It caused another kind of heterogeneity problem named metadata heterogeneity problem. Recently, the research on metadata gateway approach that allows metadata heterogeneity is being more actively progressed. However, the existing commercialized systems that have been implemented with the metadata gateway approach are dependent on a metadata schema. In this paper, we propose a message conversion system which separates the mapping information from the mapping rules between heterogeneous metadata schemas. The proposed system dynamically manages standardized data elements by applying ISO/IEC l1179. Therefore, the proposed system provides the set of standard data elements to create consistently metadata of new databases and provides a fundamental resolution to the metadata heterogeneity problem.

The UML is a widely accepted standard in object-oriented modeling. As the UML is semantically rich, we can describe in detail the system that will be developed, but we cannot guarantee the correctness and consistency of the designed model. Therefore, it is important to minimize the error by verifying user models in an early stage. In this paper, we propose a method for verifying the consistency of UML structural diagrams and behavioral diagrams using OCL verification rules and meta-metamodel. The consistency is a nature for checking whether the structural diagrams and behavioral diagrams are coherently designed according to a specific requirement. First we build meta-metamodels of the structural diagram and behavioral diagram that are described with the UML diagrams and the related elements, we derive rules for verifying the consistency from each meta-metamodels, and then formally specify with the language such as OCL for automatic verification. Finally, we verify the usefulness of the rule through a case study.

This study aims to research the Kisho Kurokawa's architectural concepts, that are comprised of complex theories system, for globalization of Korea. Kurokawa's architectural concepts are composed by Metabolism, Metamorphosis and Symbiosis. And intermediate zone, ambiguity, multivalence are theories that work as media in changing process levels to three main concepts and these are used as media of Metamorphosis which embody Symbiosis. Metabolism include concepts of Metamorphosis and Symbiosis. Symbiosis is comprise of concepts of Metabolism and Metamorphosis, and is a ultimate goal of these three main concepts. Metamorphosis works as a medium in changing process levels from Metabolism to Symbiosis.

The information about eBook cannot be added automatically to library catalog because the eBook Service Provider does not provide enough eBook metadata. Therefore, this paper was developed the eBook library's metadata in order to maintain the compatibility and interoperability analyzed the eBook service provider's metadata, KS X 6100 metadata, Dublin Core, MARC, and TEI Header, and extracted common meradata elements from them. We defined these common metadata elements as a core element and added other elements that uniquely describe eBook characteristics as a detailed adn additional elements for eBook metadata.
