Design of the Client/Server Driver for MIDISK Based on Window CE
Yoonsik Kwak,Hyunsik Yoon,Taeho Noh,Seokil Song 한국정보기술학회 2005 한국정보기술학회논문지 Vol.3 No.5
The internet disk that this paper presents for mobile device makes a long-distanced storage recognized as a local storage. The MIDISK consists of designing parts of the protocol of internet disk for mobile device, the client, and the server. It was implemented by information device of Windows CE environment For this purpose, this paper suggests a design of the client and server drivers. The client driver produces the virtual disk driver for mobile as and is the key technology of the client, which provides the user with interface environment under which the user can control the disk. It also processes the interface for virtual disk driver and offers a networking that brings data from a distant area or sends them to it. A Linux server will be developed as the server for MIDISK. The server is designed to perform communications according to the protocol between the mobile device and MIDISK, which makes it possible to process properly to the controlling demands of mobile device, and to provide the mobile device with logical volume by connecting it to a large volume storage.

This paper discusses the design and implementation of context-aware sensor tags that can be attached to various containers. The tags are designed to be utilizable in non-standardized fruit boxes, and can identify whether fruit has been loaded in a box because they are attached inside the box. After recognizing normal load status, data are sent only when there is content. The tags were designed and implemented to measure distribution by detecting the movement of the fruit box, and sending data through a context-aware function that determines whether fruit is loaded, and a data-transmission event; the tags also send data periodically, even when the fruit box is not moved

In this paper, we present that it is about the monitoring system for disaster prevention using an antiseptic water production device and a car license plate recognition system. The antiseptic water production devices consist of a storage, spray, connection part, and an antiseptic water unit. The car license plate recognition systems consist of an automatic recognition system for cars and license plate recognition system. Using the above described components, we could implement the monitoring system for disaster prevention that consist of realtime monitoring, objects, configuration, user, login/out management part. As the results, we could prove the function of disinfection for an antiseptic water and monitor the information about cars to be used for disinfection. Simultaneously we could get the information about cars and drivers. Also, using the functionality of implemented systems integration management, we could obtain usability and efficiency in agriculture to be characteristics.

본 논문은 무선 센서네트워크 환경에서 온도 및 습도 데이터의 획득을 위한 장치 설계에 관한 것이다. 유비쿼터스 기술 및 컴퓨터 기술의 발전으로 그 활용 분야가 급속하게 확대되고 있는 센서네트워크 기술의 데이터 입력 장치인 센서노드, 즉 센서모듈의 설계에 관한 것이다. 데이터 입력 장치로 온도 및 습도 데이터의 수집 및 전송기능을 수행 할 수 있는 8비트 마이크로프로세서와 온도 및 습도 측정 장치가 결합된 모듈로서 기존의 상용화 시스템이 갖고 있는 기능을 사용 할 수 있을 뿐만 아니라 저 비용의 기능 구현 및 사용자 기반 센서설계의 용이성을 확보 할 수 있었다. According to the development of ubiquitous and computer techniques, the application fields of sensor network have been enlarged. We present the design and implementation of sensor node which is the most important component of sensor network techniques in this paper. The proposed sensor node is implemented with 8-bit microprocessor, and temperature and humidity sensing device to gather temperature and humidity data in real world. It achieves low production cost and user convenience, and also has the feature os existing commercial sensor node. Though our experiments, we show that deviation of temperature and humidity are 5°Cand 23.2% respectively, and the proposed sensor node is reliable in real applications.

In this paper, we study how the physical environment (temperature, humidity) during the distribution of farm products effect the quality and shelf life of farm products. Subsequently, we monitor the distribution environment of farm products with sensor network. Then, based on the monitoring results, we predict the quality of farm products. Finally, we analyze how the distribution & store environment effects the quality of farm products. Also, through the analysis we study a predication method for the quality of farm products based on the monitoring results of sensor network. As the results for apples, we can obtain the shelf life limitations period, weight reduction rate, and prediction equation based on the quality factors-temperature, humidity. As the experimental results, we can obtain the merchantability and optimal distribution time for agro-foods.
