  • In this paper, a remote emergency stop system to improve the safety of an automated driving vehicle is proposed. One of the most serious problems of the previous wireless remote emergency system is that it does not work when the wireless channel is damaged in case of an emergency because it is composed of a single communication channel. Therefore, the proposed remote emergency stop system composed of a portable wireless remote system and a stationary wireless remote system is designed and the remote emergency stop system for automated driving vehicles is developed. By applying it to an automated driving vehicle to check it's performance, the wireless remote system is tested. Emergency stops using the portable wireless remote system is tested when the stationary wireless remote system is disconnected. Also, emergency stops using the stationary wireless remote system are tested when the portable wireless remote system is disconnected. The results of the emergency stop test show a satisfactory performance.

  • Adaptive cruise control Stop&Go system has been developed to reduce the driver's workload on highway or public road. This system is characterized by a moderate control of engine and brake actuator. A control system capable of modeling driver's driving characteristics has been constructed to provide natural vehicle behavior in full speed driving. But, ACC Stop&Go system has some limitations. One of the limitations is a detection limitation on near cut-in situation. This paper presents development of the near cut-in test procedure, finding of the limitation value on near cut-in scenario and performance comparisons on ACC Stop&Go system.

  • Transportation of goods by rail in border areas requires considerable time, money, and human resources. Therefore, in this study, a blockchain-based non-stop passing system is proposed to solve this problem. In this study, each transit station and train are designated as one network node, and the corresponding node participates in the blockchain network to record and verify data. In the process, we will design a blockchain network using Docker and design a network interface. Without changing the data and information generated in the existing legacy clearance system, it is possible to configure a blockchain network to ensure the integrity and reliability of the data and to minimize the consumption of time and human resources. The railroad non-stop passing system aims to change the existing legacy system to a blockchain-based non-stop passing system.

  • It is necessary to develop the one stop system in order to protect our marine environment rapidly from oil spill accident. The purpose of this study is to develop real time database for oil spill prediction modeling and implement real time prediction modelling with ESI and server-client GIS based user interface. The existing oil spill prediction model cannot provide one stop information system for public and government who should protect sea from oil spill accident. The development of multi user based information system permits integrated handling of real time meteorological data from external ftp. A server-client GIS based model is integrated on the basis of real time database and ESI map to provide the result of the oil spill prediction model. End users can access through the client interface and request analysis such as oil spill prediction and GIS functions on the network as their own purpose.

  • Tidal power is one of new and renewable energy sources. Tidal power is generated by using the gap in the water level between the water outside and inside the embankment. All tidal power plant in Korea were being operated by import of turn-key from abroad. The know-how and technology which are the most important to build predictive control system has become increasingly difficult to obtain from advanced countries because most of them avoid to transfer, which the domestic development of the control system is needed. In this paper, a study on start stop system at water turbine-generator for tidal power plant at the beginning of development was presented. For improvement the efficiency and develope of core technology of the start stop system, the technique and characteristics of tidal power, modeling, maximum generation calculation method, and optimal control of joint control system in Sihwa tidal power plant were studied.

  • The purpose of the paper is to analyze situations and its prospect of Single Window System for custom's one-stop service in Japan and to suggest effective application was to improve of in Korea's Customs systems. In response to the growing demand for lower trading costs and shorter and more predictable lead times with the advancement of the international trade supply chain, the Single Window System for import/export and port-related procedures was launched on 23 July 2003 in Japan. The concept of the Single Window System is to establish a comprehensive computer interface system that enables users to complete all import/export and port-related procedures required under different laws and regulations in a single input and single transmission. To realize the concept, the data elements and submission times of the various systems were harmonized, and manual procedures, such as quarantine and immigration, were computerized. Then, all the necessary systems, such as NACCS, Port EDI System, and Crew Landing Permit Support System, were interconnected as a Single Window System. Close cooperation among other governmental organizations and the private sector was a key factor in the successful development and smooth utilization of the System so that it fully met all parties' needs. It is anticipated that operating costs will be greatly reduced and trade facilitation will be enhanced as a result of the simplification of procedures. Korea Customs advocates the Single Window System as a best practice at ASEAN and WCO to contribute to the development of regional and international capacity building.

  • Cost reduction and equality by exempting re-scanning of passengers, baggage and cargo secured from the first airport of departure, mainly in the European Union/European Economic Area(EU/EEA), Switzerland, etc. One-Stop Security(OSS) is being promoted to maintain the level of security while increasing speed and convenience, and movement is expected to expand worldwide. Therefore, this paper establishes the basic concept of OSS through a literature review of ICAO Standards and Recommended Practices(SARPs), and analyzes the actual conditions of OSS implementation in major countries such as the United States and the EU. It is intended to present the political, economic benefits for Korea and highlight the urgency of implementing the OSS system in the aviation industry including the cargo sector. Therefore, the practical implications of strengthening international cooperation through the expansion of government and airport operators OSS implementation to overcome the resource shortage problem of the existing national air cargo security system and to strengthen the status as a global aviation powerhouse were drawn up. There is academic significance that it raised the need for effective implementation of OSS, which was not previously covered.

  • 본 논문에서는 기존의 콘텐츠 관리 시스템의 한계를 극복하고자, 하나의 콘텐츠 관리 시스템의 트랜스코딩 엔진을 이용하여 IPTV, WEB, Mobile, Smart Device 등에 서비스할 수 있는 콘텐츠 관리 시스템(CMS)을 개발한 사례를 소개한다. 개발된 CMS는 하나의 콘텐츠를 동시에 여러 개의 콘텐츠로 트랜스코딩하여 각 각의 디바이스에 자동으로 인지하여 최상의 콘텐츠를 서비스함으로써 CMS 추가 도입에 대한 부담감을 줄이고, 관리자의 개입을 최소화시킴으로써 효율적인 콘텐츠 관리를 할 수 있도록 설계 되었다. 스튜디오에서 제작된 콘텐츠에 대한 자동화시스템과 모바일에서 촬영된 영상에 대한 자동관리 기능으로 활용에 중점을 두고 있으며, 추후 콘텐츠 생산에 대한 기능을 추가함으로써 콘텐츠에 대한 One-Stop Service를 할 수 있도록 발전시켜갈 계획이다.
