With the development of modern society, we are all living in a world where information is shared through mass media and environment. Just as there was an identifier for the approach of information in the past analog environment, there is a demand for the continuous development and research of an original identifier for each and every digital contents of the changing digital environment. In order to present the need for standardization of effective construction concerning digital contents, this study examines the identifiers system structure of ISBN and ISSN of the analog environment and URL, URN, URC, which are under the URI system of the digital environment. After analyzing the problems of different URL identifiers construction in each university library's OPAC system, this study presents a standard device of effective identifiers patterns.

We introduce the standard content identifier Universal Content Identifier (UCI) and a watermarking system that embeds UCI for the broadcast content distribution services. Our proposed UCI embedder is designed in consideration of integrating with the previously established broadcast system and protecting the illegal distribution of broadcast contents. Our goal is that when broadcast content is transmitted, 28 byte UCI is embedded imperceptibly in the content itself in real-time and the embedded UCI is successfully extracted not only in the typical format used in the broadcast content distribution service but also in the illegally distributed broadcast contents. Usually the illegally distributed contents are modified from the original by changing resolutions, frame rates, or adjusting colors. In this paper, we present a watermarking scheme that embeds 28 byte UCI in broadcast content in real-time while keeping the visual quality high and the embedded watermark robust enough to survive through the various modification. The experimental results show that the embedded UCI remains in the various modified versions of content and that the visual degradation by embedding is not noticeable.

The role of digital content identification system is being considered as a useful solution for the content management system and service system. Integrated Copyright Number(ICN), only one domestic identifier to the managing of copyright, can provide the service model in the copyright industry, because it include the information of copyright between the creator and the service provider on the digital work. Universal Content Identifier(UCI), has developed on the focus of digital content service, is somewhat lacking on the copyright management, but it is expected that systematical management and distribution system for copyright and digital work to be able to build as that make up for disadvantage with each identifier's advantage by UCI associate with ICN. In this context, This article can suggest the efficiency integrated structure and the service scenario. Therefore it is contribute to the efficient using and the effective running in the digital identification system.

RFID 기술의 신속한 확산을 위해서는 태그의 저가격화, 초소형화, 저전력화, 보안 및 프라이버시 문제, 태그식별자의 표준화, 다중태그 식별문제등이 우선적으로 해결되어야 한다. 특히, 식별영역 내에 다수의 태그가 존재할 경우에 다중태그 식별(multi-tag identification)을 위한 충돌방지(anticollision) 알고리즘은 RFID 시스템 구축에 있어서 반드시 해결해야 하는 핵심기술이다. 기존의 충돌방지 알고리즘들은 구현의 복잡성과 낮은 성능이 문제로 제기되고 있으며 지금까지 충돌방지와 관련하여 진행된 대부분의 연구들은 각각 고유한 형태의 태그식별자 체계를 기반으로 진행되어 왔으며 태그식별성능에 대한 비교연구도 부족한 상태이다. 본 논문에서는 저비용(low-cost) RFID 시스템에서 현재 표준화가 진행되고 있는 96비트 EPC (Electronic Product Code) 코드를 기반으로 병원 환경에서 태그에 우선순위를 부여하여 충돌이 발생하면 우선순위가 가장 높은 것부터 읽어들일 수 있는 그룹 트리 알고리즘을 제안하였다.

무장 비행 궤적 간 간섭을 식별하여 아군 무장간 충돌을 방지함으로써 단위 시간 당 교전 효과를 극대화하는 것은 다무장 대지 무기체계 운용에 있어서 필수적이다. 기존 연구에서는 연산 부하의 최소화를 목표로 3차원 무장 비행 궤적을 2차원 평면의 사격선으로 변환하여 간섭을 식별하는 알고리즘을 제안하였다. 그러나 기존 연구는 2차원 평면에서 사격선간 교차점이 발생할 경우 간섭으로 식별하고, 이에 대한 무장 할당을 해제함으로써 무장 활용도를 감소시키는 문제가 있었다. 이를 고려하여 본 논문에서는 교전 효과 최대화를 위한 효율적인 무장 궤적 간 간섭 식별 알고리즘을 제안한다. 제안하는 알고리즘은 2차원 평면에서 사격선간 교차점이 발생할 경우, 해당 사격선을 3차원 평면에서 비행 궤적 간 비교 연산을 수행하여 실제 간섭 여부를 식별함으로써 무장 활용도를 최대화하는 것이 가능하다. 성능 평가 결과, 제안하는 기법은 기존 기법에 비해 궤적 교차수는 최대 52.1% 감소하였으며, 그에 따른 표적 할당율은 최대 6.9% 향상됨을 보임으로써 그 우수성을 확인하였다.

Introduction of domestic digital content identification system mean to building district identification by supplying international identification system and interoperability that reflect domestic special state than accept it as it is. This study presented an policy direction for the domestic digital content identification system by the results that analyzed of the identification systems that were commonly used internationally. An identification system is composed to a registration authority, registration agencies, registrants. There should be defined their roles and set up their cooperative system to be able to bring efficiency into more.

The development of Semantic Web basically requires knowledge induced from the formalization and semantization of information, and thus ontology should be introduced as a knowledgization tool. URI(Universal Resource Identifier) is an indispensible scheme to uniquely indicate individuals on ontology. However, it is difficult to find the use cases of URI in real data including science and technology papers. This paper describes the method to construct internal and external human resource information based on URI from the papers. We use co-authors, e-mails, publication date, and affiliation for discriminating authors with the same strings. HRST(Human Resources devoted to Science and Technology) is referred to acquire URIs for human resource. We expect the internal and external human resource information would be adopted to outcome analysis applications such as researcher network analysis and outcome statistics.

The development of Semantic Web basically requires knowledge induced from the formalization and semantization of information, and thus ontology should be introduced as a knowledgization tool. URI(Universal Resource Identifier) is an indispensible scheme to uniquely indicate individuals on ontology. However, it is difficult to find the use cases of URI in real data including science & technology publications. This paper describes the method to construct human resources based on URI which are the critical components on national R&D reference information ontology. We use co-authors, e-mails, publication date, and affiliation for discriminating authors with the same strings. HRST is referred to acquire human resource URIs. We expect the human resources would be adopted to outcome analysis applications such as researcher network analysis and outcome statistics.

The rapidly increasing use of the Internet and advancement of the communication network, the explosive growth of digital contents from personal home pages to professional information service the emerging file exchange service and the development of hacking techniques . these are some of the trends contributing to the spread of illegal reproduction and distribution of digital contents, thus threatening the exclusive copyrights of the creative works that should be legally protected Accordingly, there is urgent need for a digital copyright management system designed to provide centralized management while playing the role of bridge between the copyright owners and users for smooth trading of the rights to digital contents, reliable billing, security measures, and monitoring of illegal use. Therefore, in this study, I examined the requirements of laws and systems for the introduction of the centralized management system to support smooth distribution of digital contents, and also researched on the current status of domestic and international centralized management system for copyrights. Furthermore, 1 tried to provide basic materials for the standardization of digital contents copyright management information through the examination of the essential elements of the centralized digital contents management such as the system for unique identification the standardization for data elements, and the digital rights management (DHM) .
