  • Various application systems are developed using RFID as a part of ubiquitous computing, and it is expected that RFID chip will become wide-spread for the distribution industry especially. Efficient and efact intelligent-type of warehouse management system is essential for small-to-medium-sized enterprises in the situation having a trouble in the viewpoint of expense and manpower. In this paper, we implement small-scale warehouse management system using log-based context awareness technology. This system is implemented to be controlled on web, configuring clients to control RFID readers and building up DBMS system in a server. Especially, it grasps user's intention of storing or delivering based on toE data for the history of user's access to the system and it reports user's irregular pattern of warehouse use and serves predictive information of the control of goods in stock. As a result, the proposed system can contribute to enhance efficiency and correctness of small-scale warehouse management.

  • Harmful gases which are generated from various rout at growth environment of livestock ban have a direct and indirect bad influence to the livestock and farmers, and also step-up breeding density and long-term exposure to the sealed environment of winter can be fatal. In this paper, we propose a gas measurement system for monitoring gases of ammonia, hydrogen sulfide, volatile organic compounds, etc. which arise from the muck. The measurement system consist of both wireless gas sensor node and gas recognition software using a Fuzzy Min-Max neural network. To evaluate the performance of suggested system, gas measurement experiments are performed in laboratory environment by using the designed wireless gas sensor node. And we show the performance through classification test for the target gases by the designed gas recognition software.

  • NFC(Near Field Communication)는 13.56Mhz를 사용하는 근거리 무선통신으로 PC, 휴대폰 등의 전자 기기간 양방향 데이터를 송수신할 수 있는 기술이다 [1]. 안드로이드를 중심으로 채택되기 시작한 NFC 기술은 스마트폰과의 연결을 통하여 새로운 다양한 비즈니스 모델을 만들어 내고 있다. 본 논문에서는 이러한 NFC기술을 대형 마트 도메인에 적용하여 마트를 방문하는 고객이 편리하고 빠르게 장을 볼 수 있도록 도와주는 애플리케이션 개발내용에 대해 기술한다. 본 애플리케이션을 이용하여 고객은 장보기 전에 구입할 상품을 장바구니에 미리 등록할 수 있으며 예산금액을 설정할 수 있다. 고객이 마트를 방문 시 출입구에 부착되어있는 NFC 태그를 인식하여 장바구니에 등록한 상품에 관한 맞춤형 정보를 얻을 수 있고 마트 진열대의 상품에 장착된 NFC 태그를 스마트 폰으로 인식하여 장바구니에 등록된 상품과 체크하며 장보기를 실시한다. 장보기 완료 후에는 포스기에서 NFC 태그를 인식하고 결제방법을 선택하고 결제를 한다. 결제 후 상품은 포장단계에 적용되고 포장이 완료된 후 배송하게 된다. 대형마트에서는 본 시스템을 갖춤으로써 고객들이 좀 더 편리하게 쇼핑할 수 있도록 도와줄 수 있다.

  • In smart cold chain, environment monitoring (for example temperature, humidity, and etc) is an important. Especially, because monitoring may be broken on passage, in order to success of cold chain management, it is important that seamless monitoring. To solve this problem, we implement mobile gateway supporting RFID and demonstrate using of RFID middleware emulator.
