Abstract: Disclosed herein are a method for user intention profiling and an apparatus for the same. Behavior data may be created based on logs collected in real time with regard to the online behavior of a user who accesses an online site, the purchase intention of the user and the item of interest may be detected based on the behavior data, keyword ranking information related to the user may be extracted in consideration of the similarity between a keyword vector corresponding to the item of interest and item models created based on multiple items registered in the online site, and a user intention profile for the user may be created based on at least one of the item of interest, the keyword ranking information, and a purchase probability included in the purchase intention.

Abstract: Disclosed herein are a method for providing marketing management data for optimization of distribution and logistics and an apparatus for the same. The method and apparatus detect, in real time, respective purchase intentions of multiple users who access an online site, generate demand forecast data, in which items and regions are taken into consideration, based on respective pieces of user information and the purchase intentions of the multiple users, and generate and provide marketing management data for optimizing distribution and logistics of multiple items provided by the online site, based on the demand forecast data. Further, information that assists item sellers in managing inventory or in managing the supply and demand of products may be provided.

Abstract: Disclosed herein are a method for predicting a purchase probability based on a behavior sequence of a user and an apparatus for the same. The method and apparatus collect, in real time, logs for a user who accesses a shopping site, generate a Uniform Resource Identifier (URI) sequence corresponding to the online behavior of the user by arranging the logs in temporal sequence, and calculate a product purchase probability of the user by comparing the URI sequence with a purchase probability model corresponding to the shopping site. Further, the current purchase intention of a customer may be more accurately detected, and thus information about a product currently of interest to the customer may be provided.

Abstract: Disclosed herein is a test apparatus for early landslide detection fully-connected with pore water pressure, surface displacement and shear surface. The test apparatus calculates a factor of safety of a slope based on variation in pore water pressure, surface displacement and shear surface of a soil mass, and predicts a change in factor of safety, thus making early landslide detection possible. In the test apparatus, while a container of a slider is moved with a soil mass loaded into the container, shear surface and surface displacement environment is provided, and the shear strength and the shear stress of the soil mass can be calculated based on the pore water pressure and the weight of the soil mass. Thereby, the factor of safety of the soil mass can be calculated, and early landslide detection can be realized by using variation of the factor of safety of the slope.

Abstract: A method of implementing a location-based service within a building is provided. The method includes receiving, from at least one electronic device, a plurality of data sets indicating information of wireless signals which the at least one electronic device measures for each time or for each location within the building; determining a similarity between the plurality of data sets; generating a logical path by integrating similar data sets; and generating a wireless signal map within the building by mapping the logical path to a physical path of the building.

Abstract: A ring shear apparatus for measuring a shear strength of soil samples. The ring shear apparatus considering a wall-slip effect including: an upper ring for forming a first accommodation portion having a ring shape in which soil samples are accommodated; a lower ring for forming a second accommodation portion that corresponds to the first accommodation portion of the upper ring and has a ring shape in which soil samples are accommodated, closely attached to a lower portion of the upper ring and rotatably installed relative to the upper ring; a rotating unit for rotating the lower ring relative to the upper ring; and a shear strength measuring sensor combined with the upper ring and for measuring a shear strength of the soil samples, wherein a plurality of protrusions that protrudes from the lower ring is formed on an inner circumferential surface of the lower ring along a circumferential direction of the lower ring in order to prevent the soil samples from being slid when the lower ring is rotated.

Abstract: Provided is a method for remediating arsenic-contaminated soil, including: a collection step of collecting arsenic-contaminated soil; a washing step of adding the collected soil to a washing solution, which is acidic in nature and provides reducing conditions to the soil, so as to remove arsenic from the soil and transfer the removed arsenic to the washing solution; a solid-liquid separation step of separating the soil and the washing solution from each other after the washing step; and a post-treatment step of removing arsenic from the washing solution, which was separated in the solid-liquid separation step, and employing the soil for remediation.

Abstract: A transmission gate switch includes a switching unit to conduct a switching operation between first and second nodes in response to a switching signal, and an isolation unit to prevent the switching unit from being turned on by a negative swing of the first or second node while the switching unit is being turned off.

Abstract: A debugging apparatus and method for correcting errors in embedded systems are provided. More particularly, a non-stop debugging apparatus and method for correcting errors in embedded systems in a development environment configured of a host and a target are provided. With the non-stop debugging apparatus and method, application programs of the embedded systems can be easily debugged without the user having to frequently execute operation and stoppage of the application programs, in time-sensitive application programs and the application programs on which it takes a user much time to perform. Also, according to the non-stop debugging apparatus and method, commands for the non-stop debugging and information required for other debugging are stored in the host system, thus making it possible to minimize the load of the target system so as to conform to the characteristics of the embedded systems sensitive to resource limitations.
