This paper proposes the system to manage profiles effectively that are necessary for content adaptation services. The proposed profiles for providing content adaptation services are used in the various services. However, currently, there are lack of the interoperability in profiles due to the different configuration, which is affected by different services. The service providers also spend a lot of operating costs by operating profiles respectively. To solve theses problems, the system which can integrate and manage the various kinds of the profiles is necessary. Based on profile services architecture and the previous profile research to the necessary functions for the proposed integrated management system of profile are derived. The proposed integrated management system of profile supports also the functions such as receiving, processing, saying, managing, providing and supports profiles that are made of RDF form and comply with the CC/PP specification. The metadata constitution technique and dynamic technique for effective content adaptation also are applied. As a result of performance evaluation the proposed techniques improve the performance 4% compared with the previous techniques.

As a result of the study, the poorest keywords were information, big data, management, policy, government, law, and smart. In addition, as a result of network analysis, related research was being conducted on topics such as data industry policy, data governance performance, defense, governance, and data public. The four topics derived through topic modeling were "DG policy," "DG platform," "DG in laws," and "DG implementation," of which research related to "DG platform" showed an increasing trend, and "DG implementation" tended to shrink. This study comprehensively summarized data governance-related studies. Data governance needs to expand research areas from various perspectives and related fields such as data management and data integration policies at the organizational level, and related technologies. In the future, we can expand the analysis targets for overseas data governance and expect follow-up studies on research directions and policy directions in industries that require data-based future industries such as Industry 4.0, artificial intelligence, and Metaverse.

The Public Data Portal(data.go.kr) is a gateway for searching and using public data in South Korea. In 2021, the Ministry of Public Administration and Security established individual portal maintenance plans. Individual portals refer to portals built by public institutions in Korea other than the public data portal. According to the maintenance plan, the Korea Intelligence Information Society, the operator of the public data portal, needs to establish operating and data integration plans to link the public data portal and individual portals. In this study, we investigated the current operating status and data integration methods of the public data portal in South Korea, the United States, the United Kingdom, and France, and proposed that the adoption of a top-down approach is efficient when integrating data. In addition, we divided the specific procedures that should be pursued when integrating data into five stages: determination of data integration standard methods, analysis of metadata status, expansion of operating infrastructure, confirmation of data import, and launch of services.

Various standard terminologies in medical field are composed individually to different structure. Therefore, information on crosswalking between the terminologies is needed to combine and use the terminologies. Lots of mapping tools have been developed and used to create the information. However, since those tools deal with specific terminologies, the information is restrictly created. To overcome this problem, some tools have been developed, which perform mapping tasks by composing various terminologies. However, the tools also have difficulty of composing automatically the terminologies because the terminologies have different structures. Therefore, in this paper, we propose a method for composing and using the terminologies in the developed mapping system with keeping the original structure of the terminologies. In the proposed method, additional terminologies could be added on the mapping system and used by making metadata involving information on location and structure of the terminologies. And the mapping system could cope flexibly with the changes of the structure or context of the terminologies. Moreover, various types of mapping information could be defined and created in the system because mapping data are constructed as triplets in ontology. Therefore, the mapping data can be transformed and distributed in different formats such as OWL, RDF, and Excel. Finally, we confirmed the usefulness of the mapping system based on the proposed method through the experiments about creating mapping data.

Rapid computing environment, change of the application structure, and various user demand will increase the demand of the software development. Version control is helpful to improve productivity using delta, and useful to establish component from existing data of source code. This paper presents the design and implementation of the version control system. which is composed of retrieval system and delta management system. In retrieval system, vanous retrieve methods arc proposed. This methods provides the process methodology with filename, content, size and date. Various retrieve methods arc important for the effective delta management. Meta data can be easily composed for the delta management by these methods. Compared with other systems, this implemented version control system has some advantage. First, for delta management, version maintenance for delta management becomes easier by integrating the forward and back-ward methods. Second, delta managent part of a project is to unite the forward and backward method. the effieiency of this system is to increased in management. Also, this system supports a thechnique of using the database and files for project repository and makes the version management more effective.

This study aims to apply the concept of Internet of things to library and interpret a library as ecological space where human, thing and data are communicating and organically networking through internet. First, we defined various things existing in physical spaces of the real world and internet spaces as elements of Internet of Things. Then we proposed to apply a semantic web platform to integrate different meta-data formats and communication protocols from things. Finally, we provide the model of Internet of Things based on Semantic web to utilize a variety of information from things for library management and user service.

The reductions of troops/human resources, and improvement in combat power have made Korean Department of Defense actively adapt 4th Industrial Revolution technology (Artificial Intelligence, Big Data). The defense information system has been developed in various ways according to the task and the uniqueness of each military. In order to take full advantage of the 4th Industrial Revolution technology, it is necessary to improve the closed defense datamanagement system.However, the establishment and usage of data standards in all information systems for the utilization of defense big data and artificial intelligence has limitations due to security issues, business characteristics of each military, anddifficulty in standardizing large-scale systems. Based on the interworking requirements of each system, data sharing is limited through direct linkage through interoperability agreement between systems. In order to implement smart defense using the 4th Industrial Revolution technology, it is urgent to prepare a system that can share defense data and make good use of it. To technically support the defense, it is critical to develop Multi Repository Meta-Data Management (MRMM) that supports systematic standard management of defense data that manages enterprise standard and standard mapping for each system and promotes data interoperability through linkage between standards which obeys the Defense Interoperability Management Development Guidelines. We introduced MRMM, and implemented by using vocabulary similarity using machine learning and statistical approach. Based on MRMM, We expect to simplify the standardization integration of all military databases using artificial intelligence and bigdata. This will lead to huge reduction of defense budget while increasing combat power for implementing smart defense.

Ontology-based approaches for automated information integration are being widely investigated. The existing approaches explicitly represent the semantics of information sources in ontologies and let the computer system, through aligning or merging the source ontologies, provide a global view of information sources. The problem of aligning or merging different ontologies is a well known problem, and the inter-ontology mappings play an essential role in information integration. To enable simple and well-founded mappings , the ontologies of information sources should be modeled with the same world view and with the same manner of representation. This paper introduces an ontology modeling framework for component libraries, which is developed based on the Guarino's theory of upper ontology . This paper discusses the results of modeling ontologies of mold and die component libraries based on the framework. A Web-based implementation automatically merges the source ontologies.
