A new cultivation diary system based on environment sensor data and Web 2.0 with Flex is suggested, to improve the previous system using the subjective data of cultivators. The proposed system is designed by applying an object-oriented model called mini-architecture, in order to enhance the reliability of software as well as promote stability to overall system design. The environment sensor data such as temperature and humidity are used to develop the new reliable diary. Also, an active interface based on Web 2.0 and Android as the user GUI are implemented to maximize the convenience while recording the cultivation diary. The result of the performance evaluation shows that the data from sensors has 99.1% of correlation with that of analogue.

Most of the current cultivation log is recorded by growers manually or whose environment information is input based on the grower's own judgement. It is not easy for growers to record the image of disease and insect pests in the cultivation log. In this regards, u-Farm cultivation log management system based on Web 2.0 and smart phone is introduced in this paper, that is used for the effective cultivation management and grower's convenience. In the system, the value of environment information is transmitted to servers via sensors. It designs and implements Web 2.0 Flex so as to make the cultivation log more reliable and provide users with active, convenient GUI in case the log is recorded by desktop. In this process, detailed modules are designed by object-oriented UML considering the reusability and maintenance of the system. Moreover, the system introduced in this paper is proved to be more excellent by the qualitative assessment compared with the other researches.

Objective: In this paper, work time for the representative fruit crops are collected and analyzed using time-diary method, and the collected data were compared with the directly observed work time using GPS device. Background: There is no consistent conclusion which measurement method for work time is accurate. Most of the research results were collected from the environment other than rural area. Therefore, there is need to review reliability of the measurement methods for the agricultural work which are carried out for a long duration. Method: Top five crops (apple, pear, grape, sweet persimmon, and peach) were selected according to the number of farms and cultivation areas. We let fruit growers fill a work diary during one cropping period. A difference between the work-time that was recorded by the farmers and the direct observed worktime using GPS device were analyzed. Results: Average direct work time for the five fruit crops found to be 7.1% of the total work time. Conclusions and Applications: Reliability was secured by recording the daily work diary at each work stage while aware that direct observation is carried on. Data which are being collected by government institutions are obtained by the memories of the respondents. Therefore, it is needed to try the method adopted by this study in order to collect more accurate data.
