Recently the solution integrated of vision and motion controller which are important element in automatiomn system has been many developed. However typically such a solutions has a many case that integrated vision processing and motion control into network or organized two chip solution on one module. We implement one chip solution integrated into vision and motion controller using Zynq-7000 that is developed recently as extended processing platform. We also apply EtherCAT to motion control that is industrial Ethernet protocol which have compatibility for open standardization Ethernet in order to control of motion because EtherCAT has a secure to realtime control and can treat massive data.

Modern state-of-the-art military aviation assets are operated with independent embedded real-time operating systems(RTOS). These embedded systems are made with a high level of information assurance. However, once the systems are introduced and installed on individual platforms for sustaining operational employment, the systems are not actively managed and as a result the platforms become exposed to serious threats. In this paper, we analyzed vulnerability factors in the processing of mission planning data and maintenance-related data for fighter aircraft. We defined the method and form of cyber attacks that modulate air data using these vulnerabilities. We then proposed a detection module for integrity detection. The designed module can preemptively respond to potential cyber threats targeting high - value aviation assets by checking and preemptively responding to malware infection during flight data processing of fighter aircraft.

Recently, GIS(Geographic Information System) has been developed to personalized service for providing the specialized services that is aimed to personal user based on mobile communication. The existing GIS system provides comprehensive and simple information but GIS System for personalized service must provide the adjustive information through the personal interest profile based on POI(PoInt of Interest). This paper describes the intelligent retrieval geographical information service module for providing personal oriented geographic information service. Our proposal model consists of user preference profile, acquisition of POI through hybrid network (Wireless LAN, CDMA), service platform and implementation of prototype system. Implementation model can apply to the life information service like restaurant, oil station, convenient store and etc.

Industrial HMI(Human Machine Interface) system is the main element among the factory automation processes and have been used to monitor and control operation and status of machine in factory with PLC. This HMI often brings heavy loads to the system development and difficult decreasing the system because it tends to use a specific system per each manufacturer. Therefore, in this thesis, we have developed an embedded linux-based embedded industrial HMI software modules which can be used for touch panel embedded system to solve these problem. In this module, we have used the Qt/Embedded software component because it can be used by all systems which support C++ compiler without modifying the existing codes. We can design more flexible system and network configuration because we have used the wireless communication module. In this thesis, we implement linux-based HMI software modules which are capable of wireless communication as well as bringing the mobility to the overall system and finally decreasing the system development loads by using the general purpose OS with competitive price.

This paper proposes a test method for compliance of SMS encoder and decoder modules with 3GPP (3rd Generation Partnership Project) specification on SMS PDU (Protocol Data Unit). The existing tools have focused on providing an SMS gateway and on helping to view and edit a single SMS PDU, which rarely help to resolve the compliance test problem. The proposed compliance test method is based on an automatic generation of SMS PDUs fully compliant with the 3GPP specification by using QuickCheck library written in Haskell. By applying the proposed method to a C-based SMS encoder and decoder in Linux Mobile platform, we have found out several critical bugs such as wrong interpretation of time stamps in BCD format. The automatic SMS PDU generator is reusable in that it only depends on the 3GPP SMS specification. The QuickCheck library is also applicable for testing other network protocol data encoders and decoders, as used in this paper.

The development trend of jet fighter's avionics system architecture is the digitization of subsystem component functions, increased RF sensor sharing, fiber optic channel networks, and modularized integrated structures. The avionics system architecture of the fifth generation jet fighters (F-22, F-35) has evolved into an integrated modular avionics system based on computing function integration and RF integrated sensor systems. The integrated modular avionics system of jet fighters should provide improved combat power, fault tolerance, and ease of jet fighter control. To this aim, this paper presents the direction and requirements of the next-generation jet fighter's avionics system architecture through analysis of the fifth generation jet fighter's avionics system architecture. The core challenge of the integrated modularized avionic system architecture requirements for next-generation fighters is to build a platform that integrates major components and sensors into aircraft. In other words, the architecture of the next-generation fighters is standardization of systems, sensor integration of each subsystem through open interfaces, integration of functional elements, network integration, and integration of pilots and fighters to improve their ability to respond and control.

최근 미니홈피, 블로그 등의 개인 홈페이지가 활성화되면서 개인의 생활 경험 정보를 기록으로 남기고자 하는 욕구가 증대되고 있다. 이와 같은 시도는 주로 영상이나 텍스트에 의존한 기록이 주를 이루고 있다. 정보 통신 기술의 급속한 발전은 디지털 라이프로그라는 개념으로 개인의 전반적인 일상 생활을 디지털 미디어로 기록해 두고자 하는 시도를 가능하게 하고 있다. 라이프 로그에서 저장되는 정보는 단순히 개인이 보고 듣는 정보뿐 아니라 개인의 주변상황 및 신체상태 등 그 다양성이 더욱 커질 수 있다. 이러한 다양한 정보를 개인의 실생활에서 수집하기 위해 개인이 일상 생활에서 사용하는 사물에 정보 수집 및 처리 기능을 부가하자는 연구가 활발히 진행되고 있다. 본 고에서는 이와 같이 지능화된 사물을 지능형 가젯(gadget)이라 부른다. 지능형 가젯은 단순한 사용자의 개인 생활 정보를 수집하는 수단 외에도 가젯들 간의 상호 정보 교환으로 사용자의 현재 상황 정보를 인지할 수 있으며 라이프 로그가 저장된 서버와의 정보 교환으로 사용자의 과거 경험 정보로부터 사용자의 의도나 취향을 분석할 수 있다. 이러한 정보를 활용하여 사용자에게 가장 적합하고 특화된 서비스를 제공할 수 있는 환경을 구현할 수 있다. 본 고에서는 이를 위한 기본이 되는 라이프 로그 서비스를 위한 지능형 가젯의 각 구성 모듈인 지능형 가젯 플랫폼, 지능형 가젯 네트워크, 그리고 지능형가젯 미들웨어의 기술 동향과 라이프 로그 서비스의 연구 사례에 대해 살펴본다.

In the smart media environment, magazine industry has been experiencing a transition to ecosystem of value network, which includes high complexity and ambiguity. Using case study method, this article conducts research on digital convergence, the model of magazine ecosystem and adaptation strategy of global magazine companies. Research findings have it that the way of contents production of global magazines has been based on collaborative production system within communities, expert communities, creative users, media contents companies and magazine platform. The system shows different patterns and characteristics depending on magazine-driven platform, Platform-driven platform or user-driven platform. Collaboration system has been confirmed in various cases: Huffington Post and Zinio which collaborate with media contents companies, Amazon magazines and Bookish with magazine companies, Huffington Post and Wired with expert communities, and Flipboard with creative users and communities. Foreign magazine contents diverge into (paper, electronic, app and web magazine) as they start the lively trades of their contents on the magazine platform. In the area of contents uses, readers employ smart media technology effectively such as cloud computing, artificial intelligence and module individualization, making it possible for the virtuous cycle to remain in the relationship within communities, expert communities and creative users.

Environment is an important factor in city life. Environmental elements are a subject that must be discussed in the smart city plan, but there is still a lack of information and data sharing in the urban environment, so improvements are needed. As part of the intelligent of Nanjing, this research has made in-depth investigation into the construction and service demand of environmental information, and has carried out the research on the design and construction of intelligent information platform that conforms to Nanjing intelligent city planning, improves environmental quality and provides environmental information service. The visualization of information is also studied. The result is an important module in the construction of intelligent city in Nanjing.
