A plasma display panel includes barrier ribs disposed between a front substrate and a rear substrate and define discharge cells. Sustain electrode pairs are disposed on the front substrate. Address electrodes are disposed on the rear substrate in a direction to cross the length direction of the sustain electrode pairs. A front dielectric layer covers the sustain electrode pairs, and has grooves formed in a direction parallel to the length direction of the sustain electrode pairs such that the grooves have slopes in a direction from the rear substrate towards the front substrate with ends of the sustain electrode pairs being located on a lower surface of the front substrate where shadows of the slopes are cast. A rear dielectric layer covers the address electrodes. Phosphor layers are coated in the discharge cells and a discharge gas fills the discharge cells.

A method of coding a moving picture is provided that reduces blocking artifacts. The method can include defining a plurality of defining pixels S0, S1, and S2, which are centered around a block boundary. If a default mode is selected then frequency information of the surroundings of the block boundary is obtained. A magnitude of a discontinuous component in a frequency domain belonging to the block boundary is adjusted based on a magnitude of a corresponding discontinuous component selected from a pixel contained entirely within a block adjacent the block boundary. The frequency domain adjustment is then applied to a spatial domain. Or, a DC offset mode can be selected to reduce blocking artifacts in smooth regions where there is little motion.

A nitride-based semiconductor LED comprises a substrate; an n-type nitride semiconductor layer formed on the substrate; an active layer formed on a predetermined region of the n-type nitride semiconductor layer; a p-type nitride semiconductor layer formed on the active layer; a current spreading layer formed on the p-type nitride semiconductor layer; a p-electrode formed on the current spreading layer, the p-electrode having two p-type branch electrodes; and an n-electrode formed on the n-type nitride semiconductor layer on which the active layer is not formed, the n-electrode having one n-type branch electrode. The n-type branch electrode is formed so as to be inserted between two of the p-type branch electrodes, and a distance from the outermost side of a transparent electrode adjacent to the n-electrode to the p-electrode is identical at any position.

An apparatus and method for coding and decoding an image are provided. The apparatus for coding the image includes a spatio-temporal information prediction/compensation unit, a recovered image processor, a residue generator, a quantizer, and an entropy encoder. The spatio-temporal information prediction/compensation unit generates a predicted image by predicting and compensating spatio-temporal information including at least one of temporal prediction information from a current image and a recovered previous image, and spatial prediction information from a recovered current image. The recovered image processor performs a spatio-temporal noise removal process on the recovered current image using the spatio-temporal information, and stores the resulting noise-removed image. The residue generator generates a residue image obtained by subtracting the predicted image from the input image, and the quantizer outputs quantized coefficients by quantizing the residue image. The entropy encoder generates a bit stream by entropy coding the quantized coefficients.

A context knowledge modeling method is provided. The context knowledge modeling method includes the steps of: a) defining a context knowledge space as a two-dimensional space based on an abstract level and an application domain of knowledge; b) locating a share ontology as a highest level of the abstract level for defining a common ontology concept at a plurality of applications and services performed in various environment and domains; c) locating at least one of domain ontologies as a lower abstract level than the share ontology by taking over the ontology concept defined at the share ontology and defining a class and an attribute specialized at a corresponding domain and a developing application; and d) locating one or more instance bases expressing knowledge about real objects to have a lower abstract level than the domain ontologies.

Methods of forming a contact structure for semiconductor assemblies are described. One method provides process steps to create an inner dielectric isolation layer after the contact region is protected, which is followed by the formation of the self-aligned contact structures. A second method provides process steps to create an inner dielectric isolation layer after the self-aligned contact structures are formed.
