There are provided a printed circuit board and a manufacturing method thereof. The manufacturing method of a printed circuit board includes: preparing a substrate having active regions and non-active regions, the non-active regions being formed on edges thereof; printing resists on dummy portions corresponding to the non-active regions of the substrate by using an inkjet printing method; curing the resists; and performing plating on the active regions of the substrate. The resists are masked on the dummy portions corresponding to the non-active regions of the substrate to prevent plating from being performed on the dummy portions, thereby reducing manufacturing costs.

Disclosed is a method of predicting user's position. This method comprises, creating information on a plurality of location clusters by processing a plurality of position data for a user with a probability based clustering algorithm; receiving a current position data of the user and determining a first location cluster to which the current data is mapped among the plurality of location clusters; and creating second information related to a probability that the user moves from the first location cluster to a second location cluster among the plurality of location clusters. The position data is a data tuple including latitude, longitude, and time. For all the plurality of location clusters, the information includes a determined representative position value of each of the location clusters.
