현재 전 세계 체약국들은 증가하는 항공수요를 충족하고 공역의 이용 효율성 및 항공기 운항의 경제성 등을 제고하기 위해 국제민간항공기구(ICAO)에서 전략적으로 개발하고 채택한 차세대항법시스템(New CNS/ATM, PBN 등)의 각종 항법 및 통신 어플리케이션 등을 도입 적용하고 있다. 이 가운데 AIDC(ATS inter-facility Data Communication)는 조종사와 관제사간 반복적으로 이루어지는 교신(Verbal Communication)사항을 포맷화한 후 데이터로 송출하여 조종사와 관제사 양측 모두의 업무로드를 감소시키며 주파수 점유 시간을 단축시켜 주파수 활용도를 크게 증가시키고 있다. 또한, 비영어권 국가와의 음성 통신시 부정확한 발음 등으로 야기 될 수 있는 인적요인(Human Factor)을 사전 제거하는 등 많은 혜택(Benefits)을 제공하고 있다. 비록 이번 연구에서 항공 AIDC의 모든 요소가 VTS에 1:1 적용 되지는 않지만 AIDC의 주요 요소(TOC, AOC 등)와 우리 해상교통 실정에 맞는 응용 요소(RTOC)를 추가하여 주파수와 관제센터는 다르지만 관제구역이 서로 인접해 있는 구역에 적용시켜 잠재적 위험요소를 사전에 예방하고, 궁극적으로 Service provider로서 이용자 중심의 VTS를 설계하고자 한다.

유비쿼터스 컴퓨팅 환경의 실현 가능성이 높아지면서 Automatic identification and Data Capture(AIDC)에 대한 많은 연구들이 이루어지고 있다. AIDC 기술 중 하나인 Radio Frequency IDentification(RFID)는 라디오 주파수에 따라 반응하는 태그를 이용하여 사람이나 사물을 인식하는 기술이다. 또한 RFID 특성을 지원하면서 발생 이벤트를 효율적으로 처리하기 위해 다양한 미들웨어가 개발되고 있다. 그러나 미들웨어의 지원에도 불구하고 RFID 시스템 개발자는 많은 부가적 지식을 알아야만 한다. 이 점을 해결하여 RFID 기술을 편리하게 사용하도록 돕는 Business Aware Framework(BizAF)이 제시되었다. 본 논문에서는 BizAF를 기반으로 여러 애플리케이션을 개발한 경험을 바탕으로 RFID 비즈니스 이벤트들을 생성하기 위한 모델링 프로세스를 제시하고자 한다.

In this paper, a method to guarantee system continuity is developed, which can be applied to discontinuity problem in the time domain of restructurable control system. This method can be summarized as input alternation using weight change considering convergence speed of system mode. Input is changed from 'system continuity guarantee input,' which is defined as a input that minimizes the change of state variables, to 'alternative controller input,' which is selected by Neil's PI/EAM[3]. AIDC aircraft model is used for simulation. By showing the waveform of system input and state variable, we can sure that this method is effective for depression of system shock like jerk.

Pipe spool is the most important element of plant equipment in plant construction site. Currently, the plant construction site manage the pipe spool location and usage history by handwriting. Frequently, the pipe spool is moved to unpredictable places by field workers in many construction sites and in cases like this, the pipe stool is replaced with another similar pipe spool. Since it's hard to determine the exact location of some of the pipe spools, it takes unnecessary time and labour to find the missing pipe spools, which proves that stock management is not under control. The purpose of our system is to make the identification of real-time location of the field pipes possible by attaching UHF RFID tags to the pipe spool, which will be used to connect with UHF RFID reader and antenna on vehicles. A field test conducted by the proposed system resulted in the success rate of 98% and the missing 2% was recuperated by hands-on correction, which proved that stock management through the proposed method can be 100% effective. The proposed system is expected to reduce labour costs and make stock control of assets possible, as well as applicable to similar stock management environments.
