In this paper, we introduce a smart city-cyber-security-grid-matrix methodology, as a result of research on overall cyber security of smart cities. The identified cyber security risks that threaten smart cities and smart-city-cyber-security-threat list are presented. The smart-city-cyber-security-requirements necessary to secure the smart city cyber security with the developed smart city-cyber-security-grid-matrix are given in this paper. We show how the developed smart city-cyber-security-grid-matrix methodology can be applied to real world. For it, we interlocked the developed smart city-cyber-security-grid-matrix methodology with the cyber-security-framework of the National Institute of Standards and Technology, and developed a framework-based smart city-cyber-security-grid-matrix. Using it, it is easy and comfortable to check the level of cyber security of the target smart ciy at a glace, and the construction and operation of the smart city security system is systematized.

스마트 폰을 비롯한 스마트 TV 등 여러가지 스마트 기기의 보급으로 인해 스마트 기기 간의 연동에 대한 필요성이 증대되고 있다. 본 논문에서는 스마트 TV와 스마트 폰을 연동하기 위한 게임 프레임워크를 제시하고, 시범 콘텐츠를 통해 제시된 프레임워크의 효용성을 증명하였다. 스마트 기기 사이의 연결 문제는 기본적으로 이기종 간의 연결 문제로 볼 수 있다. 이러한 문제는 이기종 기기 사이의 데이터 송수신과 보안까지 고려해야 하기 때문에, 핵심적인 데이터는 클라우드 컴퓨팅 개념을 도입하여 서버에 저장하고 스마트TV에서는 이 데이터를 이용해 게임을 수행하는 형태로 작동한다. 제시된 프레임워크는 게임을 비롯한 여러 가지 관련 분야에 적용될 것으로 예상된다.

Major developed countries are seriously considering smart factories to increase their manufacturing competitiveness. Smart factory is a customized factory that incorporates ICT in the entire process from product planning to design, distribution and sales. This can reduce production costs and respond flexibly to the consumer market. The smart factory converts physical signals into digital signals, connects machines, parts, factories, manufacturing processes, people, and supply chain partners in the factory to each other, and uses the collected data to enable the smart factory platform to operate intelligently. Enhancing personalized value is the key. Therefore, it can be said that the success or failure of a smart factory depends on whether big data is secured and utilized. Standardized communication and collaboration are required to smoothly acquire big data inside and outside the factory in the smart factory, and the use of big data can be maximized through big data analysis. This study examines big data analysis and standardization in smart factory. Manufacturing innovation by country, smart factory construction framework, smart factory implementation key elements, big data analysis and visualization, etc. will be reviewed first. Through this, we propose services such as big data infrastructure construction process, big data platform components, big data modeling, big data quality management components, big data standardization, and big data implementation consulting that can be suggested when building big data infrastructure in smart factories. It is expected that this proposal can be a guide for building big data infrastructure for companies that want to introduce a smart factory.

An overall responding security-centered framework is necessary required for infringement accidents, failures, and cyber threats. On the other hand, the correspondence structures of existing administrative, technical, physical security have weakness in a system responding to complex attacks because each step is performed independently. This study will recognize all internal and external users as a potentially threatening element. To perform connectivity analysis regarding an action, an intelligent convergence security framework and road map is suggested. A suggested convergence security framework was constructed to be independent of an automatic framework, such as the conventional single solution for the priority defense system of APT of the latest attack type, which makes continuous reputational attacks to achieve its goals. This study suggested the next generation convergence security framework to have preemptive responses, possibly against an APT attack, consisting of the following five hierarchical layers: domain security, domain connection, action visibility, action control, and convergence correspondence. In the domain, the connection layer suggests a security instruction and direction in the domains of administrative, physical and technical security. The domain security layer has consistency of status information among the security domain. A visibility layer of an intelligent attack action consists of data gathering, comparison and decision cycle. The action control layer is a layer that controls the visibility action. Finally, the convergence corresponding layer suggests a corresponding system of before and after an APT attack. The administrative security domain had a security design based on organization, rule, process, and paper information. The physical security domain is designed to separate into a control layer and facility according to the threats of the control impossible and control possible. Each domain action executes visible and control steps, and is designed to have flexibility regarding security environmental changes. In this study, the framework to address an APT attack and load map will be used as an infrastructure corresponding to the next generation security.

제4차 산업혁명시대를 맞이하면서 정보통신기술 융복합과 지능정보기술은 스마트 사회 전반에 걸쳐 많은 영향을 끼칠 것으로 전망하고 있다. 하지만 우리나라에서는 학습, 교육 및 훈련을 위한 지능정보기술 표준화 기반이 빈약하여 스마트 사회에 발맞춰 창의적 미래인재 양성에 걸림돌이 되고 있다. 따라서 본 연구에서는 교육에서의 신기술 표준 도입이 절대적으로 필요하다고 판단하여, 전문가들의 의견을 토대로 과거, 현재 및 미래에 활용될 교육정보 표준기술의 방향을 제시하고자 하였다. 이를 위하여 해당 표준 기술에 대한 타당성과 객관성을 확보하고, 미래 기술을 예측하기 위하여 산 학 연 관 교육 및 정보통신기술 표준 전문가들에게 3차례의 델파이 및 6차례의 패널 토의를 하였다. 그 결과 지능정보사회를 대비한 교육기술 표준 요소 도출을 하였으며 중 장기 표준화 프레임워크를 제안하였다. 이는 디지털 지능정보 사회에서 이러닝의 미래 표준화 기술 정책에 기여할 것으로 보인다.

Due to the development of information technology, Convergence and Creative Economy became hot issues. For example, products become more intelligent and services are likely to be connected and integrated around core services or provided as bundle solution. Meanwhile products and services are integrated in the context of mutual supplementation, which leads to Servitization of Products and Productization of Services in many industries. Previous studies have addressed Convergence with different terms and definitions such as Convergent, Multicategory Multifunctional Product, Clouding Service, Bundle and so on from one perspective such as consumers, suppliers or technology according to a wide range of academic approaches. Thus, this study attempted to suggest the most typical convergence products released in the convergence environment and categorize those products. Furthermore, this study has pointed out the problems in the New Product Development Framework discussed in the studies on marketing by taking the situation of the public sector into account and then suggested "New Service Development Framework in the Public Sector" that are different from traditional e-Gov. approach basically and will enable the government to create public information service and provide them to enterprises or citizens. It also emphasized the importance of Business Conceptualization Stage in the framework; argued that there is a necessity of an integrative study from the perspective of technology on the basis of the approach from the perspective of marketing and Policy such as a study of consumer behaviors, design and marketing channel and Policy Integration for the development and dissipation; and furthermore suggested the cases-the development/Diffusion of Transportation Card Service in Seoul and CFC (Call for Collaboration) in Singapore-in order to verify the framework. There is a need to supplement New Service Development Framework so it is able to reflect the distinct characteristics of the public sector from the academic perspective and be used as practical guidelines for SI (System Integration) business to shift into IT Service business. Last but not the least, this study has suggested the limitations and the directions for the future studies.
