The method includes generating a 3D facility model for time-series information mapping using a 3D facility model, receiving input information on a desired time-series information type and a time-series information showing method, retrieving time-series information required to be visualized on the basis of the input information on the time-series information type and the time-series information showing method, mapping the retrieved time-series information to the generated 3D facility model according to the input time-series information showing method, and integratedly visualizing the 3D facility model and the time-series information mapped to the 3D facility model. When the apparatus and method are used, household-specific time-series information is precisely mapped and visualized to the corresponding 3D positions of a 3D spatial model, so that the time-series information in a 3D virtual city model can be integratedly visualized.

A method for converting a mobile web application into a native application (the term “app” has the same meaning as the native application) and an apparatus using the method are disclosed. The method for converting a mobile web application into a native application may include: the steps of receiving at least one of a web implementation document that implements the mobile web application and a uniform resource locator (URL) for a local file; separating and analyzing a user interface element of the mobile web application based on the at least one of the web implementation document and the local file; and converting the mobile web application into the native application by mapping the analyzed user interface element to a native control that implements the native application.

摘要:
Provided is a distributed constant type filter. In a stacked body formed by stacking a plurality of printed circuit boards, signal line coil patterns on adjacent printed circuit boards face each another and are electrically connected together at both ends, and ground line coil patterns on adjacent printed circuit boards face each other and are electrically connected together at both ends. Accordingly, the distributed constant type filter has an attenuation characteristic superior to conventional distributed constant type filters while having an equivalent circuit completely different to the conventional distributed constant type filters. In addition, attenuation characteristics can be obtained without being greatly affected by a deviation upon a manufacturing process, and a process of manufacturing the filter is simple.
