The invention provides flavorful low-fat cheeses that are readily and inexpensively made from high-fat cheeses. Crosslinked bulk materials are heated to a compression deformable temperature, and pressure is applied to change a transverse dimension of the material. The system parameters include a mass of the gyroscope, two main-axis spring constants, a cross-axis spring constant, two main-axis damping coefficients, a cross-axis damping coefficient and an angular velocity. Next, the image data that are stored in the texture buffer are read out and subject to a specific image processing algorithm by the graphic processing unit, and then stored back to the texture buffer. The controller controls, if an utterance overlaps with another utterance in the chronological order, an order of displaying the translated texts corresponding to the overlapped utterances. The dressing has an aperture to accommodate a drainage tube and a slit extending from the aperture to an outer edge of the dressing.
