An integrated sieve device for particle size screening of a soil sample is provided, the device comprising: a particle size screening unit having at least one sieve and configured to screen the soil sample by particle sizes and to drop the soil sample; a body housing in a cylindrical shape, wherein a part of a lateral surface of the body housing is open, wherein the particle size screening unit is detachably coupled to an inner lateral surface of the body housing; a sample reception unit mounted at a lower portion of the particle size screening unit coupled to the body housing and configured to collect soil and water discharged below the particle size screening unit by being screened by the sieve; and a water supply unit mounted at an inlet formed on an upper end of the body housing and configured to supply water into the particle size screening unit.

Integrated sieve device for particle size screening of soil samples

The present invention relates to a shale gas extracting device, and provides a shale gas extracting device comprising: a canister, which is vertically and rotatably provided on a canister support vertically provided on both sides of a base, has an receiving space for accommodating a drilled rock sample and a ball mill together in a sealed manner, and has an injection opening at one side of a top thereof; a driving means for vibrating the canister such that the rock sample is crushed by mixing with the ball mill accommodated in the canister; a heating means for heating the canister; and a vacuum pipe, a pressure pipe, a sensor pipe, an injection pipe and an extracting pipe sequentially and detachably coupled to the injection opening of the canister.

Shale gas extracting device and extracting method therefor

Provided is a method of measuring dissolved methane in seawater, including: a) injecting a sample into a vacuum container containing a cadmium chloride solution injected thereinto and refrigerating the vacuum container; b) shaking the vacuum container, and achieving temperature equilibrium with an ambient temperature; c) separating the dissolved methane from residue by passing the sample in the vacuum container through a methane separator; and d) analyzing the separated dissolved methane by a mass spectrometer. According to the method of measuring dissolved methane in seawater of the present invention, a recovery rate of dissolved methane may be maximally increased to improve an analysis rate accordingly, and an analysis of dissolved methane may be conducted even with a small amount of sample, and in addition to the measurement of the dissolved methane, a sulfur isotope analysis may be simultaneously conducted by using a sample from which the dissolved methane is extracted.

Method of measuring dissolved methane in seawater

Provided is an apparatus for extracting, analyzing, and storing gas in a drilled core on a ship. The apparatus includes: a needle for core insertion inserted into the drilled core to allow the gas in the drilled core to the outside; and a first 3-way valve into which the gas passing through the needle for core insertion is introduced and which controls the introduced gas so as to be supplied to a gas storing container or gas analyzing apparatuses positioned on a ship.

Apparatus for extracting, analyzing, and storing gas in drilled core on ship

A future amount is created through demand estimation by rectifying data administrated in a logistics infrastructure through a system and a method for alternative simulation of a logistics infrastructure. In addition, an infrastructure load by a future year amount is analyzed and an alternative is selected through the load analysis.

System and method for alternative simulation of logistics infrastructure

Provided are an intelligent parcel monitoring and controlling apparatus for real-time pickup and delivery, a method thereof, a terminal for the intelligent parcel monitoring and controlling apparatus, and a method for operating the terminal. The apparatus can correct address errors, generate optimum pickup/delivery sequences, and monitor the pickup and delivery in postal or door-to-door parcel delivery services. The intelligent parcel monitoring and controlling apparatus includes: an address correcting unit for acquiring correct pickup and delivery addresses; a planned sequence generating and managing unit for generating and managing an optimum pickup and delivery sequence; a terminal monitoring and controlling unit for transmitting pickup and delivery information; a monitoring unit for displaying monitoring information which is obtained based on the pickup and delivery state information and the location information; and an information storing and managing unit for storing and managing information related to pickup and delivery.

Intelligent parcel monitoring and controlling apparatus and method and terminal for executing real-time parcel pickup and delivery and operation method thereof
