Recently, it has increased projects in the Oil and Gas industry as growing plant of overseas construction market. Therefore, domestic companies need to set some aggressive plans up that secure competitiveness of international plant business such as enhancing productivity, technological ability and statistical management. Specifically in the Oil and Gas industry of overseas plant business requires implying information in EPC (Engineering, Procurement and Construction, below EPC) more, but it has not been suggested an appropriate breakdown system for contents that manages the information each EPC phase, which lead to problems such as revision of design document, occurring duplicated work and omissions of each participant. For these problems, we find market share decreasing and competitiveness running down. Thus, for increasing practical use of contents management system and construction industry's information, this paper suggests a contents breakdown system based on BPM (Business Process Management), defines business process and systematizing knowledge needed, and finally analyzing contents information that establish information among industrial facilities in Design phase which is the weakest part of domestic companies.

A set of definitions for traceability and quick recall service function were urgently needed to facilitate handling of events threatening food safety caused by livestock diseases or germ contaminations. However, the research on the unified management system for both international and domestic livestock products distribution was scarce. The livestock products traceability evaluation model proposed in the paper was composed of four modules: the Forward Transaction Trace (FTT) module, the Backward Record Trace (BRT) module, the Forward Product Trace (FPT) module, and the Origin Pedigree (OP) module. The evaluation indexes for each module was included and finally a pilot system evaluating the proposed management model was suggested and displayed. The result of the paper was expected to be a solution to the distributed traceability system and the proposed traceability management model could be expected to any food traceability.

Despite the importance of the supply chain risk due to the negative word-of-mouth (NWOM) in social media, related research is insufficient. Thus, this study analyzes how the NWOM of the product is distributed through social media and the characteristics of the distributor based on social exchange theory. For this purpose, we collected information on car recalls from four companies using Twitter from the National Highway Traffic Safety Administration (NHTSA). Based on the Seed Tweet, a Re-Tweet (RT) network was constructed to examine the distribution and spread of NWOM, and regression analysis was performed to test the hypothesis. As a result, it was confirmed that NWOM is a small world network structure that spreads around hub users connected to many users. Moreover, it was found that the more interactive and reciprocal relations the first distributor has, the greater the speed and scale of distribution of NWOM.

In this study, we examined distribution channel relationship by using the idea of Cheong, which is a unique feeling an positive role in Korean society. Companies make great efforts to maintain long-term relationship with buyers. Understanding distinctive relationship system of each culture should precede these efforts to bring effective results. So we considered how Cheong, a meaningful factor in Korean distribution channel, affects relationship quality and performance. As a result of research analysis from 272 survey questionnaires of retailers, engaging in Crops Protected Material industry in Korea, supplier's idiosyncratic investment, retailer's Cheong, and dependence of retailers on suppliers have positive effects on relationship quality. Supplier's idiosyncratic investment and cognitive factors have the highest influence and Cheong, an emotional factor, follows. Dependence, a motivational factor has the least influence. We confirmed that retailer's cooperation and long-term orientation are directly influenced by retailer's commitment. Active cooperation of the retailer, a partner of a distribution channel, is regarded as an essential factor for supplier's effective business. Retailer's commitment increased that cooperation. Retailer's trust and commitment also decreased relationship conflicts. The results of this study imply that companies should increase idiosyncratic investment to improve relationship quality. But increasing idiosyncratic investment is limited because it requires monetary investment. Therefore companies need to recognize the importance of Cheong, revealed as a new factor, improving relationship quality and to make the best use of it. In this study, we contributed theoretically by examining the role of Cheong, and introducing its distribution discipline. We also make practical suggestions about supplier's relationship management.

Ubiquitous Computing owes Internet and development of computer network and appeared. RFID (Radio frequency Identification) technology is noted by point technology to realize this. However, PML that present in Auto-lD Center is defined point part to describe information of object, and necessary part is to use defining extension separately in actuality application. So that can define object type that can be used for electron tag data processing in RFID application service because do fetters to Auto-lD Center's PML Core in this treatise hereupon and apply in physical distribution circulation service field, designed object information data model.

The current development of digital platform-based online retail business leads to the rapid growth of freight demand and service innovation. With the demand for converged logistics technologies, our government supports R&D projects to innovate the logistics service. The digital platforms are developed based on their own standard process and data formats. It may cause interoperability and connectivity-related problems. In this research, the standard data flow to connect the data among systems is defined based on the standard process. Especially, data for connectivity is categorized into three groups, common data, connected data, and management data. It may be possible to enhance the applicability to the practical logistics business.

Is caused by with growth etc. of the digital contents circulation market which leads suddenly accommodates in order to control the network traffic which increases and the researches which are various are being advanced the explosive evidence and a electronic transaction of the Internet user. The present paper protects a digital contents and a copyright from CDN system environments which will appear the center of new network service with the plan for the dispersive DRM system of CDN bases plans. Respect this dispersion DRM package formats which provide a stronger security characteristic in the contents which is stored the operational process of the dispersive DRM system for to be defined, CDN system and of existing interoperability they present.

본 논문에서는 방송프로그램 저작권 식별관리를 위한 방송프로그램의 Video Signature와 국가표준콘텐츠식별 체계인 UCI(Universal & Ubiquitous Content Identifier)와의 연계 방안을 제시한다. Video Signature는 UCI와 같은 식별자의 인위적인 부여 과정이 없더라도 비디오 콘텐츠 자체에서 직접 특징정보를 추출할 수 있기 때문에, 이미 배포 유통된 콘텐츠에 대해서도 식별 확인이 가능하다. 따라서, 본 연구에서는 UCI 표준식별체계와 방송프로그램의 Video Signature와의 지속적인 연계를 위하여, 바이너리로 표현된 Video Signature가 포함된 UCI 응용 메타데이터를 정의한다. 그리고 UCI 표준식별체계 기반의 Video Signature 전송 및 관리 메카니즘에 기반한 방송프로그램의 저작권 식별관리 시나리오를 제시한다.

ISO/IEC 21000 (MPEG-21) 표준은 멀티미디어 컨텐츠 운용의 가치사슬(value chain) 전 과정 - 생성, 제작, 전달, 소비, 보호, 관리 및 유통 둥을 위한 하부 기반구조(infrastructure)들이 총체적으로 통합 관리, 체계화 될 수 있는 '멀티미디어 프레임워크'를 정의하는 국제 표준기술이다. MPEG-21 표준기술의 비전은 궁극적으로 사용자가 단말장치 및 컴퓨터 네트워크를 의식하지 않는 상태에서 시간과 장소에 구애받지 않고, 언제 어디서나 자유롭게 네트워크에 접속할 수 있는 환경, 즉 '유비쿼터스(Ubiquitous)' 서비스 환경에서의 원활하고 투명한 멀티미디어 컨텐츠 사용 환경 구축을 지향하고 있다. 본 논문에서는 현재까지 표준화 작업이 진행된 MPEG-21 표준기술의 개요 및 최신 표준화 동향 및 향후 진행방향에 대해서 서술한다.

CE RCD(Recreational Craft Directive, 2003/44/EC)는 24미터 미만의 레저선박을 포함하는 수상레저기구에 대한 설계, 생산 그리고 그 품질에 대한 규격을 정의하고 있는 EU 지침(European Directive)으로써, 유럽공동체는 물론이고 이를 인정하는 국가에 레저선박을 수출, 유통하기 위해서는 반드시 획득해야하는 인증규격이다. 국내의 경우 등록 및 검사에 있어 비교적 간소한 절차를 필요로 하는 소형 파워요트를 중심으로 레저선박 개발이 이루어져 왔으며, 이러한 국제인증에 기반한 설계, 생산기술에 대한 연구가 부족한 실정이다. 본 연구에서는 CE RCD의 평가 모듈과 절차를 분석하고 이를 레저보트 개발에 효과적으로 적용하기 위한 방안을 연구하였으며, 50피트급 레저보트 설계 사례연구를 통해 그 효용성을 보였다.
