As UCI (Universal Content Identifier) identification system becomes a national standard for content distribution, many digital contents are distributed through UCI identification system. However, problems associated with copyright infringement and copyright contracts occur due to lack of copyright information. ICN (Integrated Copyright Number), a code system developed for copyright management, includes copyright-related information for the purposes of usage settlement and accounting, illegal usage monitoring, and content filtering. ICN, however, has no information about distribution and content properties. Therefore, the linkage and integration between UCI and ICN can be a basis for the transparent and effective distribution of digital contents. In this paper, we propose a model for linking and integrating UCI and ICN, developing the efficiency in the value chain of each identified system by analyzing political factors and key technical elements between the two identification systems.

In this paper, the design of URL structures and managements for UFID(Unique feature Identification) based wireless communications is presented with the combination of GIS and URL address informations. As a result of IPv6 based UFID wireless communications, new methods for URI(Uniform Resource Identifier) informations and UFID communication systems are proposed with a 6byte coded 128-bit IPv6 DNS system for the presentation of 1,500,000 korean buildings.

Recently, Internet technology has developed, various programs are being created and therefore various codes are being made through many authors. On this aspect, some author deceive a program or code written by other particular author as they make it themselves and use other writers' code indiscriminately, or not indicating the exact code which has been used. Due to this makes it more and more difficult to protect the code. In this paper, we propose author identification framework using Authorship Analysis theory and Natural Language Processing(NLP) based on Convolutional Neural Network(CNN). We apply Authorship Analysis theory to extract features for author identification in the source code, and combine them with the features being used text mining to perform author identification using machine learning. In addition, applying CNN based natural language processing method to source code for code author classification. Therefore, we propose a framework for the identification of authors using the Authorship Analysis theory and the CNN. In order to identify the author, we need special features for identifying the authors only, and the NLP method based on the CNN is able to apply language with a special system such as source code and identify the author. identification accuracy based on Authorship Analysis theory is 95.1% and identification accuracy applied to CNN is 98%.

A Unique Feature Identifier(UFID) is a way of referring to a feature, generally representing a tangible feature in the real world. In other words, a UFID uniquely identifies the related feature in the database and is normally used to link two or more databases together. This paper presents a UFID system aiming at the internal uses for National Geography Institute(NGI) as well as external uses for National Geographic Information System(NGIS) generally to link datasets together. The advantage of the proposed type of UFID lies in the meaningful nature of the identifier in providing a direct spatial index - administrative area and feature code. The checksum character proposed in this research is designed to remove any uncertainty about the number being corrupt. It will account lot digit transposition during manual input as well as corruption in transfer or processing.

The field of automatic identification using RF is the one of the emerging ubiquitous computing areas. Early RFID techniques was focused on hardware areas, but RFID middleware has recently gained a lot of attention, which collects and filters tag data, and provides it to enterprise applications. The RFID middleware proposed by EPCglobal only can process EPC tag data, and cannot handle the KKR code which is defined by korean organization. So in this paper, we propose a method which can process the KKR code in RFID middleware systems. Using our approach, the RFID middleware can be extended as general ubiquitous middleware systems which process not only EPC code but also KKR code.

본 연구과제는 건설업체의 현재 문제점은 각 업체별로 상이한 분류 및 식별코드체계를 사용, 품목표기방식, 속성 포맷의 불일치, 용어와 단위의 불일치, 현 업계에서 사용하는 코드 분류체계는 호환이 되지 않고 국제적으로 사용할 수 없는 부적합한 실정이다. 따라 기존의 통합정보시스템과 별개로 관리 운영이 이원화되어 오던 각종 건설정보를 건설CALS/EC 핵심기술을 적용하며 건설표준 ERP 템플릿시스템을 개발 할 목적으로 한다. 따라서 본 연구에서는 건설표준 ERP 템플릿시스템과 건설통합분류체계의 표준코드의 연계로 건설CALS/EC 핵심기술이 적용된 건설표준ERP(통합DB)를 구축과 건설공사의 물량산출 데이터의 체계화된 물량예측과 물량공정의 통합화와 설계정보, 시공정보 및 관리유지정보의 연계하여 그리고 현장관리 및 원가관리정보의 통신망접속으로 건설통합정보를 제공한다.

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.

As global warming and depletion of fossil fuel are considered as urgent problems, the development of electric vehicle (EV) is getting more attention by automobile industry. However, the wide adoption of EVs is not coming yet, because of many issues such as long recharging time and high cost of batteries etc. As an alternative solution to the conventional battery charging EV, the idea of battery exchanging EV is introduced. To realize the battery exchanging business model, one should solve the issues of ownership and reliability of battery. To address such issues, the concept of battery sharing should be considered together with good traceability system. In this study, we studied RFID code structure to provide better visibility and traceability for shared EV batteries. The proposed RFID code and code generation system is based on GRAI-96 of EPCglobal and included factors such as chemical, physical, and manufacturing features. The designed code can be also used as the ID of each battery.

The purpose of this study is to distinguish industrial clusters in Korea. Based on I/O table in 2000, coefficient matrix was calculated and factor analysis was performed on the matrix. Among 38 derived industrial clusters, 5 of them were unreported clusters, which were indistinguishable. Once these 38 industrial clusters were differentiated according to I/O table, final results of clusters were produced as I/O table was converted into KSIC (Korean Standard Industry Code). Since existing studies on industrial cluster have been focused on qualitative methods such as case studies and interviews, it is expected that this study could contribute to carry out more systematic and efficient methodology.
