    • PURPOSE: A method and a storage system for controlling materialization in a storage medium using mode setting and delimiters are provided to accurately and efficiently implement the materialization by directly transferring materialization order or atomicity control requests to a storage device. CONSTITUTION: A host interface (1310) receives writing commands for writing data from a host system on a storage medium of a storage device; a group starting delimiter for representing the starting of a group inserted between the writing commands; and a group finishing delimiter for representing the finishing of the group. A controller (1330) identifies the group from the writing commands using the group starting and finishing delimiters and determines materialization order or atomicity of the writing commands based on the group. The controller processes the writing commands based on the determined result. A storage device (1350) materializes the writing commands according to the processed result.

    • PURPOSE: An active irrigation control method based on soil moisture tension and an irrigation control device are provided to start irrigation at accurate time by measuring moisture tension in a tensiometer and to determine an optimal irrigation amount and an optimal irrigation time. CONSTITUTION: An active irrigation control method based on soil moisture tension comprises the following steps: measuring soil moisture tension before supplying water to soil; determining whether the soil moisture tension value approaches a target value according to cultivated crops or not; converting the soil moisture tension value into a moisture content value if the soil moisture tension value is deficient to a target value; determining required irrigation flow needed for soil by using the moisture content value; calculating a pressure loss rate of a supply tube by respectively measuring and comparing pressures at a starting stage and an end stage of the supply tube which is used for supplying water to soil; determining an irrigation time to be proportional to the required irrigation flow and to be inversely proportional to supply flux and the pressure loss rate according to the supply tube; and supplying water to the soil for a determined irrigation time. A tensiometer is used to measure the moisture tension of soil.
