Abstract: The invention provides methods for manipulating the distribution of HIV gene sequences from a subject infected with HIV to classify whether the subject has been infected for more or less than a year. The Methods are useful, for example, in determining whether prophylactic interventions such as vaccines or drug candidates are slowing the rate of transmission in a population.

Abstract: A mobile communication terminal having a camera module and a touch screen is provided. The mobile communication terminal transmits and receives text data while performing the video call with at least one other party's terminal. The touch screen displays at least one images when the text data transmission and reception function is started, an input window for displaying text data input through the touch screen, an output window for displaying the transmitted and received text data, and at least one soft key, and a controller for controlling, when the input window or one of the at least one soft key is selected, the touch screen for changing a display method of at least one of the first image, the second image, the input window, the output window, and the at least one soft key and for displaying a touch pad comprising a plurality of keys for inputting text data.
