Online exchange is a cost-effective approach to trade goods and information among multiple sellers and buyers. Shipping industry includes lots of global entities such as shippers, liners, ship owners and shipping agents. Marine insurance companies and ship repairers and many other groups are also supporting the industry. However, international shipping exchanges are located on few cities in the world. Its our motivation that a shipping market can be online so that market participants do the dealing while sitting where they are with more efficient manner, preferable price and larger pool of candidates of trading partners. This paper presents Korean governmental project of building a cyber shipping exchange. The exchange covers ship sale and purchase, charter, insurance, freight futures, repairs, supplying of ships oil and database service. The workflows of each business were analyzed and designed to fit for online environment. The project includes design of trading mechanism, online documents, data flow, data storage and security. Online match making and trading mechanisms such as auction, reverse auction, bid are used. The whole trading process involves multiple organizations and business processes. So, this Paper focuses on how each organization would play their roles so that users can complete transactions with integrated and transparent view. The online exchange selves also as maritime portal site that links to other sites for cooperation vertically or horizontally, and serves database and information in global perspective.

R2RML is a W3C standard language that defines how to expose the relational data as RDF triples. The output from an R2RML mapping is only an RDF dataset. By definition, the dataset has no schema. The lack of schema makes the dataset in linked data portal impractical for integrating and analyzing data. To address this issue, we propose an approach for generating automatically schemas for RDF graphs populated by R2RML mappings. More precisely, we represent the schema using ShEx, which is a language for validating and describing RDF. Our approach allows to generate ShEx schemas as well as RDF datasets from R2RML mappings. Our ShEx schema can provide benefits for both data providers and ordinary users. Data providers can verify and guarantee the structural integrity of the dataset against the schema. Users can write SPARQL queries efficiently by referring to the schema. In this paper, we describe data structures and algorithms of the system to derive ShEx documents from R2RML documents and presents a brief demonstration regarding its proper use.

선진 전력시장에서는 전력산업의 환경이 수용가 중심의 시장구조로 변화함에 따라, 이들을 대상으로하여 IT 기반의 다양한 전력부가서비스가 제공되고 있다. 이러한 서비스에 대한 연구개발은, 시간이 흐르면서 단방향이 아닌 양방향 통신 기반의 소비자 중심 서비스 분야로 확대되는 경향을 보인다. 특히, 미국 EPRI의 IntelliGrid 컨소시엄에서 제시한 수용가 포탈은 소비자 영역내의 장비와 에너지 서비스 기관 간의 양방향 통신을 지원하는 통합적인 개념의 서비스 기반으로, ESP(Energy Service Provider)와 소비자는 더욱 상세한 정보를 이용하여 더 많은 이익과 혜택을 기대할 수 있다. 이에 비해 국내의 전력부가서비스 제공 수준은 아직 시작 단계에 불과하지만, 머지않아 국내 전력시장 역시 양방향 통신 기반의 수준 높은 전력부가서비스를 요구하게 될 것으로 보인다. 따라서 국내환경에 적합한 수용가 포탈 기반의 전력부가서비스 개발이 필요하며 이를 통해 수용가에게는 비용 절감이 가능한 합리적인 소비 방안을 제시하고, ESP에게는 부하 수요관리 및 투자비를 절감할 수 있는 기회를 제공해야 할 것이다. 본 논문에서는 새로운 전력부가서비스를 기반이 될 수용가 포탈을 분석하고, 현행 전력부가서비스의 현황과 동향 분석, 적용가능 기술 분석을 수행하여 그 결과를 바탕으로 국내환경에 적합한 수용가 포탈시스템 기반의 전력부가서비스 선정 및 구축 방안을 제시하고자 한다.

The purpose of this study examined how post-traumatic stress, caused when internet users in web portal or social media are defamed in cyberspace, influence on coping behaviour, through the Theory of Reasoned Action's two major factors: Attitude on behaviour and subjective norm. In so doing, it aims to provide a technical and political solution that would fundamentally prevent future victims in cyberspace. In an effort to examine its research theory, a survey was conducted on people who have had the experience of being defamed in cyberspace. The results showed, first, hypersensual has no significant influence over attitude on behaviour and subjective norm. Second, intrusion has no significant influence over attitude on behaviour and subjective norm. Third, avoidance showed significant influence over attitude on behaviour and subjective norm. Fourth, attitude on behaviour and subjective norm showed significant influence on behaviour. This study has both theoretical and practical significance; Unlike previous studies on cyber defamation with qualitative research method, this study employed quantitative method through theory-based approach. In other words, the researcher did not arbitrarily set variables, but utilized the Theory of Reasoned Action for examination.
