In this paper, we propose a ubiquitous Farming Diary System which can support the easy and reliable recording of a farming diary for the certificate on environment-friendly agricultural products by using the USN(Ubiquitous Sensor Network) technologies. By using growth-related data, the system can also control farming facilities remotely and automatically. To achieve this goal, the UFDS(Ubiquitous Farming Diary System) is consisted with 3 layers. The first 'physical layer' can collect data from sensors, cameras and facilities then controls the growth environment based on the analyzed information. The second 'Middle layer' can process and store the data from 'physical layer' to sensor manager, image manager, control manager and diary manager separately. The third 'application layer' can provide growth-related services to users through various applications. The UFDS can recording grow history information automatically and Easily. Besides, the system can make an accurate and reliable farming diary with multimedia information such as motion and sound. Furthermore, environmental information such as temperature, humidity, luminance and soil conditions (soil temperature, soil humidity, soil EC) can be monitored in real-time and the facilities managed in remote sites.

In agricultural field, environmental factors such as temperature, humidity, solar radiation, CO 2 , and soil moisture are essential elements which influence on growth rate, productivity of produce, sugar content of fruit, acidity and etc. If we manage the above mentioned environmental factors efficiently, we can achieve improved results in production of agricultural product. For monitoring and managing the growth environments, this paper suggests the Field Monitoring Server System (FMSS) which can operate with solar power. We implemented the Ubiquitous Field Server System (UFSS) in our previous work. Compared with the UFSS, this FMSS enhanced or improved the power consumption, the mobility, and user-friendly environment monitoring methods. The system collects environmental data directly obtained from environment sensors, soil sensor and CCTV camera. To implement a stand-alone system, we applied a solar cell panel to operate this system without power source. To indicate the location of this system, a Global Positioning System (GPS) module is installed on the system. Finally, we confirmed that the FMSS monitors the field conditions by using various facilities and correctly operates without helping external supports.

The surveyed control point on land surveying contributes to the performance of accurate measurement of land positions. In this paper, we propose a management system for positioning and indicating the surveyed control point using GPS and RFID. Also for monitoring the status of the surveyed control point, the system sends its location data to the remote control center via the CDMA networks. This system consists of the digital control point, management system and application. The system provides two services for managing the surveyed control point. The first service is control point remote management service that checking to the position changes of the control point. The second service is control point field management service for editing the control point information in the field. Our system makes it easy to access the control point information which is spread out the country, and can monitor the change of location by accidents, and can provide rapid maintenances. So the system can improve the reliability of the surveyed control point and reduce the maintenances costs of the control points.
