  • UxNB(Radio Access Node on-board UAV)는 3GPP(3rd Generation Partnership Project)에서 표준화된 기술 용어로서 사용자 단말에 대한 연결성을 제공하는 무선 액세스 노드로 UAV(Unmanned Aerial Vehicle)를 통해 공중에서 이동성을 가지는 기지국을 의미한다. 이는 드론 기지국, 공중 기지국, 플라잉 기지국 등으로 다양하게 언급된다. UxNB는 5G-Advanced 및 6G 환경에서의 초연결성 및 초저지연 요구사항을 충족하기 위한 필수적인 기술이므로 6G 보안 내재화를 위해 UxNB에 관한 보안 연구가 필요한 실정이다. 본 논문은 UxNB 보안에 대해 효율적으로 연구를 수행할 수 있는 UxNB 보안 테스트베드에 대해 설명하며 확장 방안에 관해 제시한다.

  • This study is the result of meta evaluation for the self evaluation of defense R&D programs in Korea. The overall meta evaluation result gained 74.3 points out of 100, so it was evaluated as 'Good'. T- test and one-way ANOVA were used to identify the difference between groups. As a result of difference analysis between groups, some evaluation items showed difference within significance level. From this analysis, it is attempted to identify possible problems and to find out the ways of improvements related to the self evaluation system of defense R&D Programs. The ultimate objective of this study is to manage the programs effectively and improve the reliability and the objectiveness of the defense R&D performances.

  • Metadata is well recognized as one of the foundational factors in archiving and long-term preservation of digital resources. There are several metadata standards for records management, archives and preservation, e.g. ISAD(G), EAD, AGRkMs, PREMIS, and OAIS. Consideration is important in selecting appropriate metadata standards in order to design metadata schema that meet the requirements of a particular archival system. Interoperability of metadata with other systems should be considered in schema design. In our previous research, we have presented a feature analysis of metadata standards by identifying the primary resource lifecycle stages where each standard is applied. We have clarified that any single metadata standard cannot cover the whole records lifecycle for archiving and preservation. Through this feature analysis, we analyzed the features of metadata in the whole records lifecycle, and we clarified the relationships between the metadata standards and the stages of the lifecycle. In the previous study, more detailed analysis was left for future study. This paper proposes to analyze the metadata schemas from the viewpoint of tasks performed in the lifecycle. Metadata schemas are primarily defined to describe properties of a resource in accordance with the purposes of description, e.g. finding aids, records management, preservation and so forth. In other words, the metadata standards are resource- and purpose-centric, and the resource lifecycle is not explicitly reflected in the standards. There are no systematic methods for mapping between different metadata standards in accordance with the lifecycle. This paper proposes a method for mapping between metadata standards based on the tasks contained in the resource lifecycle. We first propose a Task Model to clarify tasks applied to resources in each stage of the lifecycle. This model is created as a task-centric model to identify features of metadata standards and to create mappings among elements of those standards. It is important to categorize the elements in order to limit the semantic scope of mapping among elements and decrease the number of combinations of elements for mapping. This paper proposes to use 5W1H (Who, What, Why, When, Where, How) model to categorize the elements. 5W1H categories are generally used for describing events, e.g. news articles. As performing a task on a resource causes an event and metadata elements are used in the event, we consider that the 5W1H categories are adequate to categorize the elements. By using these categories, we determine the features of every element of metadata standards which are AGLS, AGRkMS, PREMIS, EAD, OAIS and an attribute set extracted from DPC decision flow. Then, we perform the element mapping between the standards, and find the relationships between the standards. In this study, we defined a set of terms for each of 5W1H categories, which typically appear in the definition of an element, and used those terms to categorize the elements. For example, if the definition of an element includes the terms such as person and organization that mean a subject which contribute to create, modify a resource the element is categorized into the Who category. A single element can be categorized into one or more 5W1H categories. Thus, we categorized every element of the metadata standards using the 5W1H model, and then, we carried out mapping among the elements in each category. We conclude that the Task Model provides a new viewpoint for metadata schemas and is useful to help us understand the features of metadata standards for records management and archives. The 5W1H model, which is defined based on the Task Model, provides us a core set of categories to semantically classify metadata elements from the viewpoint of an event caused by a task.

  • As the CG images in the films and the games are getting more realistic by the development of computer graphics, the requests of technique that can develop the various digital contents has also increased. However, the techniques developed for the studies and simulations of the ecological system and adaptation in the ocean, are insufficient compared with those on the ground. This paper propose a method of modeling to simulate the growth of ocean objects according to the variation of virtual ocean environment and the efficient metamorphosis based on the movement of the objects. By modeling the ocean objects with the anisotropic metacubes, it is possible to represent easily the growth and metamorphosis of fishes as the movement in the virtual environment of ocean.

  • The goal of next generation digital broadcasting is offering the interaction among consumers and providers as well as variety services. One of the important factors for this new broadcasting environment keeps the interoperability among providers and consumers since the environment is distributed. Therefore a standard metadata for digital broadcasting is required and TV-Anytime metadata is one of the metadata standards for digital broadcasting. The terminal nodes of TV-Anytime metadata are defined by using MPEG-7 metadata. MPEG-7 metadata is standard metadata for describing multimedia content. Therefore, if we use the MPEG-7 metadata for describing broadcasting content can offer multimedia search services like content-based search by the extension of metadata. The efficient management system for these metadata is important for offering the services with high Duality on real broadcasting environment TV-Anytime metadata and MPEG-7 metadata are technically defined using a single XML schema, so its instances are XML data. Currently, a lot of systemsfor managing XML data are proposed in many researchers and we can expect to adapt these systems for managing broadcasting metadata. But the methods used in these systems are not specific methods for managing broadcasting metadata because of methods for general-purpose. In this paper, we find the properties of broadcasting metadata and develop an efficient metadata management system that is based on the found properties. Since our systemis implemented on real broadcasting environment, we expect that the system is most efficient and suitable. Also our system is interoperable since we use XQuery as query language for querying broadcasting metadata.

  • 과학기술 분야 학회에서 발생되는 고급 학술정보는 산업ㆍ경제적 측면에서 그 효용 가치가 매우 크다. 따라서 국가 경쟁력 강화를 위해 전략적 차원으로 첨단과학기술정보를 디지털화하여 부존자원화 하고 효율적인 서비스체제를 구축하는 것이 매우 중요하다. 이러한 일련의 과정을 수행하는 것이 학술정보관리시스템이다. 한국과학기술정보연구원에서는 학술정보관리를 위하여 관계형 DB와 KRISTAL-II 기반의 관리시스템을 개발하여 운영하고 있다. 하지만 시스템에 종속적인 메타데이터의 형식과 복잡한 관리 프로세스 그리고 다양하지 못한 검색 서비스 제공과 같은 단점을 가지고 있다. 본 논문에서는 데이터의 저장관리와 빠른 검색을 제공하는 KISTI의 최신 IRMS인 KRISTAL-2002만을 사용하여 새로운 학술정보관리시스템(ACMS)를 설계하고 구현하였다. 또한 ACMS는 학술정보의 처리를 메타데이터의 표준인 XML을 사용함으로써 데이터의 유효성 검증과 타 기관의 상호대차 및 원문 교환을 손쉽게 하였다.

  • 웹의 보편화로 인하여 수많은 데이터가 산출되고 있으나 데이터 관리를 위한 메타데이터 표준은 특정 도메인에 제한적이고 너무 광범위하게 정의되어 있어 데이터가 비효율적으로 관리되고 있는 실정이다. 이를 해결하기 위해 RDF를 활용하여 자원간의 관계를 정의하고 있으나, RDF의 특성에 적합한 편집도구가 전무한 상태이다. 따라서 본 논문에서는 RDF 저작도구를 설계 및 구현함으로써 RDF를 기반으로 메타데이터의 유효성 검증을 수행하고, 기술된 자원간의 관계를 가시적으로 분석할 수 있는 노드 앤 아크 다이어그램을 지원하며, 웹자원을 N-triple로 표현하여 데이터의 효율적인 관리 및 분석을 가능하게 하였다.
