Abstract: An upconversion multicolor light-emitting polymer composite implements red, green, and blue colors at wavelengths in each specific region by mixing: an upconversion nanophosphor emitting light in red and blue colors at wavelengths in each specific region by absorbing the infrared light; an upconversion nanophosphor emitting light in green and blue colors at wavelengths in each specific region by absorbing the infrared light; and a polydimethylsiloxane (PDMS) polymer. Accordingly, a volumetric display with excellent color reproducibility may be realized with a simple manufacturing process.

Abstract: An ultrasonic image providing method of the present disclosure includes: receiving ultrasonic images; measuring a plurality of similarities for a plurality of measurement items for at least one of the ultrasonic images; comparing the plurality of similarities with corresponding default thresholds, respectively; when none of the plurality of similarities is greater than the corresponding default threshold, selecting a measurement item maintaining the greatest similarity among the plurality of similarities for a reference time; and providing an ultrasonic image for the selected measurement item as an ultrasonic image.

Abstract: The present application relates to a method of preparing urate oxidase (Uox) including a non-nature amino acid (NNAA) and Uox prepared thereby. The present application showed that the method of preparing Uox including an NNAA may be effectively used to prolong the half-life of a protein which is difficult to be linked to a carrier. In addition, the Uox produced by the method may be effectively used for various biopharmaceuticals since its efficacy is maintained and drug persistency increases due to site-specific conjugation of a carrier, a risk of an immune response is reduced, and it is easily separated due to formation of uniform conjugate.

Abstract: A semiconductor package includes a package substrate, a first semiconductor device on an upper surface of the package substrate, a second semiconductor device on an upper surface of the first semiconductor device, a first connection bump attached to a lower surface of the package substrate, a second connection bump interposed between and electrically connected to the package substrate and the first semiconductor device, and a third connection bump interposed between and electrically connected to the first semiconductor device and the second semiconductor device. The first semiconductor device has an edge and a step at the edge.

Abstract: An apparatus and method for implementing a user interface used for a group communication. The apparatus includes a constructing unit to construct a plurality of user interfaces (UIs) in a predetermined format and an output unit to display in a first image the constructed UIs and objects selected by the UIs. The UIs include a first U to select content, a second UI to select a function corresponding to the content, and a third UI to select persons who are to share the content.

Abstract: An apparatus for and a method of managing contents, the apparatus including an inserting unit to insert a mood tag so as to display a user's mood with respect to predetermined content or an importance tag so as to display the importance of the content, a classifying unit to classify the content according to a value of the inserted mood tag or importance tag, and a storing unit to store the classified content and the value of the mood tag or the importance tag that corresponds to the content.

Abstract: A method of merging data objects, including folders and opened information items, at the same level and an apparatus performing the method are provided. The data object merging method includes receiving a user command to merge two data objects; and merging the contents of the two data objects according to the input user command. According to the method and apparatus, folders can be merged at the same level and image data or text data can be input as individual objects and then, when necessary, the information items can be easily merged such that file management can be performed conveniently.

Abstract: The present invention relates to a method and an apparatus for searching a phone book in a mobile communication terminal utilizing visual spatial information of data in the phonebook. In the method, address book data is grouped by an initial character of a name or number stored in the phone book when selecting a bubble search menu. The grouped characters are represented as a bubble. When a bubble is selected, the selected bubble is zoomed in, and a character corresponding to the selected bubble is displayed and input.
