Abstract:
A managing system of a transportation facility is provided to judge state and condition of the transportation facility rapidly and reliably. A sensor part(110) is installed in a transportation facility and measures state of the transportation facility. A wireless transmission part(120) transmits data measured by the sensor part. A sate information generation part(130) generates state information of the transportation facility by comparing the transmitted data with reference data. A state information providing part(140) provides the generated state information to a user terminal(200) accessing through a communication network.
Abstract:
A repair method for a concrete incline is provided to repair a concrete incline of a large-scale concrete structure effectively and stably. A repair method for a concrete incline comprises the steps of installing a pair of rails(10a,10b) on a concrete incline(1) in upward and downward directions, installing a crushing module(100) equipped with a crushing module support(110) and a pressure water spray device(120), removing a deteriorated part by spraying pressure water to the deteriorated part of the concrete incline at high water pressure by the pressure water spray device, installing a cleaning module(200) equipped with a cleaning module support(210) and a cleaning device(220), cleaning up impurities removed by the cleaning device, installing a shotcrete work module(300) equipped with a workbench support(310) and a workbench(320), and placing shotcrete on the cleaned concrete incline.
Abstract:
A method of repairing a concrete slope using water jet and shotcrete gun is provided to make it efficient and stable to repair the concrete slop of a big concrete structure. A method of repairing a concrete slope using water jet and shotcrete gun comprises a step of spraying pressurized water to a deteriorated part of the concrete slop using a pressurized water jet and removing the deteriorated part, and a step of casting shotcrete on the concrete slop from which the deteriorated part is removed. Between the step of removing a deteriorated part and the step of casting shotcrete, a step of cleaning and drying the concrete slop from which the deteriorated part is removed is performed.
Abstract:
The present invention relates to a method for producing Angelicae gigantis radix with an increased decursin or desursinol angelate content and antioxidant activity, which is characterized by irradiating far-infrared rays to Angelicae gigantis radix; Angelicae gigantis radix with an increased decursin or desursinol angelate content and antioxidant activity manufactured thereby, and food or beverage including the same. As such, the production of farmers and the added value can be increased by providing functional materials for improving health in a novel form, which has an increased content of decursin or decursinol angelate in Angelicae gigantis radix.

Abstract:
A time synchronization method for wireless sensor network is provided to reduce a transform time and perform a time synchronization based on a transmission time at a reference transmitter. A time synchronization method for wireless sensor network includes the steps of: transmitting a reference packet for a time synchronization at a reference transmitter(S101), and stores the transmission time of the reference packet at the same time(S103); receiving the reference packet and storing the transmission time of the reference packet at a base station and neighboring nodes(S105); transmitting the stored receiving time of the reference packet at the base station(S107); and after receiving the receiving time of the reference packet transmitted from the base station at the neighboring nodes and the reference transmitter(S109), changing a local time corresponding to the receiving time of the reference packet(S111).
