  • The paper intends to summarize some guidelines for future smart structure system application in military aircraft. This preview of system integration is based upon a review on approximately one and a half decades of application oriented aerospace related smart structures research. Achievements in the area of structural health monitoring, adaptive shape, adaptive load bearing devices and active vibration control have been reached, potentials have been identified, several feasibility studies have been performed and some smart technologies have been already implemented. However the realization of anticipated visions and previously initial timescales announced have been rather too optimistic. The current development shall be based on a more realistic basis including more emphasis on fundamental aircraft strength, stiffness, static and dynamic load and stability requirements of aircraft and interdisciplinary integration requirements and improvements of integrated actors, actuator systems and control systems including micro controllers.

  • Recently, many people enjoy movies and music content through their smart devices for using public transportation like as bus or subway. However, because their concentration is aimed at content on their smart devices, passengers sometimes forget to disembark and miss their destination stations. Therefore, in this paper, we propose a destination notification system for disembarking public transport using high frequencies based on the smart devices. We tested 1,000 times real-time destination notification to performance evaluate of the proposed application and service system. According to the test results, the proposed system showed 99.4% and 99.6% accuracy and we confirmed that it could be very useful. As such, the proposed system could be a useful technology for notifying smart device users when to get off public transport, capable of global commercialization.

  • To resolve energy depletion issues in massive Internet of Things sensor networks, we developed a set of distributed energy beamforming methods with one-bit feedback and clustering for multi-node wireless energy transfer, where multiple singleantenna distributed energy transmitters (Txs) transfer their energy to multiple nodes wirelessly. Unlike previous works focusing on distributed information beamforming using a single energy receiver (Rx) node, we developed a distributed energy beamforming method for multiple Rx nodes. Additionally, we propose two clustering methods in which each Tx node chooses a suitable Rx node. Furthermore, we propose a fast distributed beamforming method based on Tx sub-clustering. Through computer simulations, we demonstrate that the proposed distributed beamforming method makes it possible to transfer wireless energy to massive numbers of sensors effectively and rapidly with small implementation complexity. We also analyze the energy harvesting outage probability of the proposed beamforming method, which provides insights into the design of wireless energy transfer networks with distributed beamforming.

  • 스마트 기기 사용의 증가는 많은 사회적 변화를 가져왔다. 특히 교육에서는 보다 높은 학습효과를 위하여 스마트 기기 적용을 연구하여 왔다. 그러나 인문교양은 전통적인 교육 패턴 뿐만 아니라 과목이 가지는 특성 때문에 정보통신에 적용하기가 매우 어려운 분야였다. 본 연구에서는 인문교양 과목을 디지털 방송에 적용하고 그 효과를 증대시키기 위한 방안을 제시하려 한다. 이를 위하여 인문교양의 스마트 콘텐츠 제작 및 연계 방안을 제시하고, 그 실효성을 위하여 디지털 방송에 적용하는 방안에 대한 설문을 통해 적용 가능성을 제시하고자 한다.

  • Objective: The aim of this study is to develop an analysis method to extract plausible types of errors when using a smart mobile in nuclear power plants. Background: Smart mobiles such as a smart-phone and a tablet computer(smart-pad) are to be introduced to the various industries. Nuclear power plant like APR1400 already adopted many up-to-date digital devices within its main control room. With this trend, various types of smart mobiles will be inevitably introduced to the nuclear field in the near future. However nuclear power plants(NPPs) should be managed considering a big risk as a result of the trend not only economically but also socially compared to the other industrial systems. It is formally required to make sure to reasonably prevent the all hazards due to the introduction of new technologies and devices before the application to the specific tasks in nuclear power plants. Method: We define interaction segments(IS) as a main architect of interaction description, and enumerate all plausible error segments(ES) for a part of design evaluation of digital devices. Results: We identify various types of interaction errors which are coped with reasonably by interaction design using smart mobiles. Conclusion: According to the application result of the proposed method, we conclude that the proposed method can be utilized to specify the requirements to the human error hazards in digital devices, and to conduct a human factors review during the design of digital devices. Application: The proposed method can be applied to predict the human errors of the tasks related to the digital devices; therefore we can ensure the safety to apply the digital devices to be introduced to NPPs.

  • 최근 들어, 스마트 단말에서 지불, 인터넷 뱅킹 등 금융업무와 관련된 중요한 정보들을 다루는 경우가 많아졌다. 또한 스마트 단말의 실행환경이 공개 소프트웨어 환경 위주로 발전하면서, 사용자들이 임의의 응용소프트웨어를 다운받아 사용하는 것이 용이하게 됨에 따라, 스마트 단말이 보안적 측면에서 취약하게 되었다. 본 논문에서는 하드웨어 기반의 스마트 단말 보안 기술의 특징을 알아본다. 또한, 본 논문에서는 스마트 단말 에서 실행되는 응용프로그램을 위한 MTM 하드웨어기반의 안전한 스마트 단말 실행환경에 대한 구현방법을 제안한다. 기존의 MTM 이 모바일 장치에 대한 신뢰의 근원 기능만을 제공한 반면, 본 논문에서 제시하는 MTM 기반 모바일 보안 환경은 모바일 장치에서 실행되는 응용프로그램이 필요로 하는 다양한 보안 기능을 제공할 수 있다. 향후, 보안 하드웨어와 연동이 가능한 IoT 기기와 게이트웨이 보안 기술, 그리고 보안 하드웨어를 활용하여 다양한 IoT 기기에 적용하여 신뢰성과 보안성을 확보하는 방안에 대한 연구를 진행할 예정이다.
