현재의 급변하고 있는 비즈니스 환경은 기업 내부의 인트라적인 업무 처리 뿐만 아니라, 기업과 기업간의 상호교환을 통한 업무 수행을 요구하고 있으며, 이러한 요구 사항에 적절하게 대응할 수 있는 전략 개념이 프로세스 상호운용성이다. 본 논문에서는 현재의 비즈니스 시장에서 이슈화되고 있는 프로세스 상호운용성을 실제적으로 구현하고자 하는 과정의 일환으로 워크플로우 표준 단체인 WfMC(Workflow Management Coalition)에서 제안하는 상호운용성 표준 메시지 프로토콜인 Wf-XML 2.0을 지원하는 프로세스 엔진의 시스템 아키텍쳐를 구성하고자 하며, 기반이 되는 프로세스 엔진은 자체 연구 제작된 e-chautauqua라는 워크플로우 시스템을 이용하여 프로세스 상호운용성이 가능할 수 있도록 확장 설계하고자 한다.

센서 네트워크에서는 센서들의 배터리의 교체나 충전이 어렵기 때문에 배터리의 수명을 최대한으로 연장하는 것이 중요하다. 본 논문에서는 센서 네트워크에서 세로-지향 데이터베이스 시스템을 적용하여 통신비용을 절감하기 위한 전략을 소개한다. 세로-지향 데이터베이스 시스템의 적용은 데이터를 컬럼으로 저장하기 때문에 질의에 해당하는 컬럼만을 불러와 메시지의 길이를 줄여 통신비용의 감소 효과를 가져와 센서들의 배터리 수명을 연장하는 효과를 가져 온다. 아울러 기존의 가로-지향 데이터베이스 시스템의 처리 방식과 비교하여 어떠한 차이점이 있는지 기술하였다.

항로표지의 효율적 관리와 연계/수집 정보의 서비스를 위해 스마트 항로표지 정보협력시스템이 요구 되었고, 항로표지 관리, 선박 사용, 육상 정보 활용을 위해서는 서비스 플랫폼이 반드시 고려되어야 한다. IMO e-Navigation 전략 이행을 위해 16개의 해양 서비스가 식별되었고, 해양 서비스 개발을 목적으로 해양 서비스 정의, 기술표준 개발에 관한 표준이 개발되었으며, 정보 교환을 위한 S-100 데이터 모델 적용이 논의 되었다. 해양 서비스 플랫폼 개발과 관련하여 서비스 인증, 검색, 메시지 전송에 관한 MCP가 개발 되었으며, 서비스 플랫폼 평가에 관한 기준이 개발되었다. 본 연구에서는 스마트 항로표지 정보 서비스 플랫폼 개발을 위해 서비스 내역과 정보협력 시스템의 구조를 분석하고, IMO/IALA/IHO 국제기구의 최신 기준에 따른 해양 서비스 플랫폼 구축 방안을 제시 하였다.

현재 전 세계는 IPv6 조기 도입을 위한 노력을 기울이고 있으며 전략적인 IPv6 인프라 구축 사업을 추진을 하고 있다. 그러나 완전히 IPv6로 전이되기 전까지 IPv4와 IPv6가 공존해야만 한다. 이에 따라 IPv4망에서 IPv6망으로의 안정적인 전이를 위한 상호 운영기술이 필요하다. 이러한 기술을 적용하기 위한 다양한 응용 프로그램의 운영을 위해서 IPv6 기반의 DNS 기술은 그 핵심적인 요소라 할 수 있다. IPv6를 지원하는 Recursive DNS는 기존의 IPv4 기반의 데이터베이스 구조와 플랫폼 및 OS를 IPv6 기반으로 변경해야 하며 IPv4 기반의 DNS 메시지 구조와 이를 처리하는 DNS의 네임 레졸루션 기능이 확장되어야 한다. 따라서 이 논문에서는 IPv6 망 전이를 위하여 변환 프로토콜인 NAT-PT를 이용한 Recursive DNS 구성 방안을 제시한다.

Despite much discussions on cyber-terrorism in South Korea, several missing issues could be addressed. This paper attempts to deal with such missing but important issues. In South Korea, there has been little attentions on cyber-terrorism with the respects of national security strategy development under macro framework responding to future security environment. This article focuses on such issues. In other words, the purpose of this paper evaluates the meaning of national security threats raised from cyber-terrorism as a mode of security threats and proposes the matter of cyber-terrorism within the development of national security strategy in the future security environment. several issues in this discussion pass some important messages for the construction of national security strategic approach framework within the future security environment adding cyber-space. in the future environment, a new space called cyber is added as an important external condition which might determine the security of individuals, societies, and nations. Therefore, the fundamental strategic framework should be prepared. After that, the trend and direction of future technological advancement should be understood and the identity, nature, and types of threat should be analyzed. Also, after that, various responses and countermeasures are together constituted in the aspect of function and system regarding various anticipated threats of the future human society including cyber-terrorism.

Advancement of science and technology have led to development of the media, which has evolved election campaign strategies. Nowadays, media development has made communication more important, and it is a growing trend where smart-device applications are widely used to facilitate communication with electors. Based on Google's Fire base Cloud Messaging (FCM) push service, which keeps up with the fast-changing election trends and supports election campaigns systematically, this research aims to help accomplish the goals of an election campaign by developing an information system and performing empirical analysis of the variables that the information system affects. The system consists of an elector's application and a management system. The management system includes browsing and management of received-and sent-message history, and direct management of the application. By managing the push system in more progressive ways, this system will help to improve the effectiveness of election campaigns and accomplish election goals.

Advertisements in modern era are not intended to be consumed only as commercial purposes, but consumed also as cultural and artistic purposes. Advertising contents' success depends on Semiotic codes revealed in advertising texts. Advertising scholar Ozoh (1998) argued that perspectives for advertising are divided into two perspective, one as marketing tool perspective and the other as communication processes perspective. Advertising planning, advertising management, advertising, and advertising evaluation of marketing perspective are significantly different from those of communication perspective. Two perspectives of advertising present various debates on what contents of advertising messages are and how advertising messages are made up. In this research manuscripts, we discuss story telling as communication tool of advertising text in terms of cultural semiotics. That is, meaning value of goods is so well revealed in use value of goods that they satisfy consumers' needs, we analyze how they satisfy consumers' needs in semiotic(symbolic) process. We apply Gremas's semantic model to coffee advertisements in France and Korea, and analyze various differences between differentiation strategies of French coffee advertisements and those of Korean coffee advertisements in terms of semiotic perspective.

The purpose of this paper is to study the send and receive of the message in the TEDI System. The TEDI System replaces a series of trade documents with electronic date, and it realizes secure and reliable transactions of data among parties by means of open networks, such as the Internet. The TEDI system is composed of Web browsers, TC Serves, a RSP Server, and Certification Servers. TEDI has development the system and legal frame work. Exporters, importers, carriers, banks insurance and companies those who engage in the trade releated business have tested TEDI system and evaluated the legal frame work from the practical point of view. TEDI is now refining the system and preparing for the service. A fundamental feature of the TEDI System is the attribution to participants of data messages through public key certificates issued by certification authorities that allow for verification of digital signatures. Access to servers maintained by such certification authorities also takes place through the internet. In principle, certificates used by any reputable certification authority may be employed as long as they are compatible with X.509 V3.

This paper analyzes the long-run brand Bacchus's TV advertisement narrative, which copes actively with changes in social and cultural circumstances. The paper focuses on the types of narrative and the consequent semantic effects used in the television advertisement of Bacchus. Through this, we aim to investigate the processes of brand strategies and transitions taken by the brand that made it a solid one. In conclusion, the summaries of distinctive meaning and value of long-run brand by examining the narrative of Bacchus in TV ads are as follows. Firstly, the narrative should be reflected in consumer's demands closely associated with changes in social and cultural circumstances. Secondly, a strong brand identity can be built by consistent management of brand image and through the cultivated effects. Lastly, it forms a bond of relationship between socio-cultural context and consumers, and functions as a communication message.
