This paper presents the user needs analysis and information visualization for the development of a semantic-based national R&D information navigation service in information service planning phase, which converges and fuses NDSL databases and NTIS databases. To investigate and analyze the user needs for improving usability, we make an improvement plan for R&D information services via a survey targeted at 30 persons, and on-site interviews targeted at 12 persons, almost of who are researchers in industries, universities and government-funded institutes. To design new information visualization service, we propose an interactive national R&D information visualization service, which is provided in navigation type, and prescribe persona and screen prototyping according to the user needs analysis. We design the national R&D information convergence/fusion architecture based on the NDSL databases, including 345,411 academic articles, 620,555 co-authors and 49,958 reports and NTIS databases including 187,466 national R&D projects. We expect that the national R&D information convergence/fusion architecture contributes to R&D information convergence/fusion as a leading model/standard and the interactive navigation-typed information visualization service strengthens usability continuously.

The software market has diversified service needs due to the expansion of the mobile market. To this end, the company intends to produce various apps by extending to the design domain based on the structured architectural assets of the domain market. In this study, we propose an evaluation model that can evaluate the efficiency for servicing assets that reflect the domain characteristics of architecture based on cloud. Based on the characteristics of ISO/IEC 25010 quality model of SQuaRE Series, a software evaluation standard, evaluation model sub-features for evaluating the efficiency of cloud-based asset data were constructed. When the architectural assets were designed as composite assets, they were designed to provide the flexibility of the evaluation model by applying the mandatory and optional evaluation elements of the sub-features that weighted the evaluation items according to the characteristics of the design domain.

For an effective warfare under the condition of NCW, the sharing of data between systems must be essential. Thus, the standardization and the integration of data which is considered as the MND-EA improvement and the Megacenter is important. The purpose of this research is to investigate the factors that affected the BI(Behavioral Intention to USE) by using the TAM(Technology Acceptance Model), That is to introduce the MDM into the national defense field which is an issue in every agency sector for data sharing. Also, based on the implementation architecture of Gartner which applies depending on the business enterprise type, the preferred architecture should be selected considering the national defense environment and the characteristics, and suggest an effective MND-MDM plan by analysing the effects on the BI. The survey was done through 19th September till the 7th of October 2011, by investigating the people in charge of the development and maintenance of the national defense information systems and the SI company's national defense team people who have experienced the development of the national defense information systems.

본 논문은 Google Dialogflow 챗봇 개발 플랫폼으로 『논어』의 메시지를 현대화한 고민상담 챗봇을 제안한다. Dialogflow 챗봇 개발 플랫폼은 사전에 설계된 대화 아키텍처에 따라 응답을 제시한다. 즉, 질문의 의도가 파악되면 별도의 문장생성 없이 사전에 입력된 시나리오가 출력되기 때문에 고전 텍스트의 낯선 어투와 함축성의 허들을 극복할 수 있다. '챗봇'을 매체로 선정한 주된 이유는 쌍방향성 때문이다. 사용자는 챗봇을 통해 원하는 내용을 주체적이고 선별적으로 학습할 수 있다. 본 연구는 인문학적 문화원형과 공학 분야의 기술을 접목한 융복합 서비스 모델을 제시한다. 이를 통해 『논어』의 메시지를 젊은 세대에게 친숙하게 전달함으로써 세대 간 문화적 공통성을 마련할 수 있다.

최근 IT(Information Technology)와 타(他)산업 간의 융 복합이 촉진되면서 새로운 융합서비스로 사물지능 통신(M2M, Machine to Machine)이 차세대 지능형 인프라 기반의 핵심 서비스로 부각되고 있다. 사물지능 통신은 기존의 통신 인프라를 활용하여 사물정보의 수집, 가공, 처리를 통해 최종 서비스를 제공하는 기술 분야로 PHY, MAC, 라우팅에 대한 기술 이슈보다는 서비스 관점에서의 네트워크 아키텍처 정의와 기능, 서비스 플랫폼 간의 연동, M2M 단말과 네트워크 간의 인터페이스에 대한 연구가 진행 중이다. 본 논문에서는 사물지능통신 융합서비스를 사용자에게 보다 편리하게 제공하기 위한 기존 플랫폼 간의 연동을 위한 요구사항과 방안을 제안한다.

For effective information sharing, data provenance semantics need to be managed effectively. Based on a scheme to represent data provenance semantics, we propose a model to calculate information sharing costs. Information sharing costs are derived from probabilities of type I and type II errors that occur in organizational information sharing, costs related to these errors, and information sharing distances between organizational units which are determined by information sharing workflows. We apply the model to various types of information sharing workflows including departmental information systems, hierarchical information systems, a hub and a stand-alone system. The calculated information sharing costs show that the hub with data standardization is best in information sharing; however without standardization its information sharing cost deteriorates to that of a departmental information system. And, any information sharing workflow is better than a stand-alone system. It is proved that the model is useful in analyzing effectiveness of information sharing workflows and their characteristics.

The application of spatial information has drawn significant attention from a wide range of industries. Railway spatial information facilitates the cooperation among related parties and improves the efficiency of asset management and operations. This study proposes the structure of Railway Object IDentifier(ROID) on railway spatial information. Current facility management and train operation are based on relative positioning system. Despite many advantages, relative positioning system causes serious problems such as the entire reconfiguration of positioning in the case of line change. Another major concern is the interface compatibility between individual facilities with different relative positioning. ROID based on absolute positioning addresses these issues, allowing the information exchange and convergence between independent parties. This study proposes ROID based on OID standard with object IDentifier and service object-oriented reference system. Our ROID employs the absolute positioning and the unique identifier, maintaining the compatibility with existing management system.

The search method that web services offers has its limitations. The search service considers only functional factors based on the client's preferences. In order to improve the web service search - which alone only considers functional factors - our research introduces an execution phase which performs both functional and non-functional factors by utilizing WSDL and matching information. Our research studies the architecture of both the service selecting method and the selecting process to help determine the best service solution for the client. We do so, taking into consideration the client's preferences. Our research also studies selecting methods for the best overall service. This service not only considers the matching of functional factors provided by the web service's selecting process, but it is also accommodating by matching the information as defined by the client. This paper research can offer the best quality service preferred by any end-user. Again, this is done by utilizing web services that considers the user's non-functional factors identified by the web service's selecting process and also by extracting matching information.

This Study aims to propose a new information security governance model design method for streamlining security governance at national strategic level. The research method of this study is to diagnose our operational experience and to derive a new model design method. In the meantime, national information security activities were perceived to be focused on knowledge transfer, and motivation of activities and securing of executive power were weak. As a result, security blind spots and frequent occurrence of large security incidents have become unresolved challenges. National cyber security governance should be grouped together as a whole systematically from the upper policy to the lower level of performance under the responsibility of the national leader. Based on this approach, this study presented the comprehensive framework of Korean security governance model and embodied it into four architectural designs such as vision, goal, process, and performance, thus deriving the foundation for future national governance model design. Further research is needed to diagnose problems in life cycle flow, security policies based on environmental changes, and new frameworks in which all subjects participate.
