Abstract: Provided are a method and apparatus for obtaining a triangle in a graph. A computing device receives an adjacency matrix in which two vertices connected to an edge are expressed in rows and columns, divides the adjacency matrix into a plurality of blocks, searches for a search area including a plurality of blocks located at (I,K), (I,J), and (J,K) satisfying I>=J>=K (where I, J, and K are block indexes) for the plurality of blocks existing in the adjacency matrix, and identifies three vertices forming a triangle based on edge information existing in the search area.

Abstract: Provided are a graph data calculation method and apparatus. A computing device divides graph data including a source vertex and a destination vertex of an edge into a plurality of blocks, and identifies an out-degree of each vertex. Next, the computing device repeatedly performs a process of calculating, in units of blocks, a weight of a destination vertex of each edge by using a pagerank and an out-degree of a source vertex of each edge existing in a block, and updating a pagerank of each vertex of the graph data by accumulating a weight of a destination vertex of each block.

Abstract: Provided are a graph data compression method and apparatus. A computing device divides graph data including information about a source vertex and a destination vertex of an edge into a plurality of pieces, generates a plurality of compressed data obtained by compressing the plurality of pieces, and stores the plurality of compressed data as a file. The computing device may generate a plurality of pieces having a size equal to or less than a predefined data size by recursively dividing graph data.

Abstract: The present invention relates to an Ecklonia cava extract, a preparation method thereof and a pharmaceutical composition for preventing or treating vascular diseases comprising the same as an active ingredient. The Ecklonia cava extract of the present invention was confirmed to have a medicinal effect on those factors involved in causing vascular diseases by the cell level experiments and the disease induced animal model experiments. Therefore, the Ecklonia cava extract of the present invention can be effectively used as an active ingredient of a pharmaceutical composition and a health functional food composition for the prevention, improvement or treatment of vascular diseases.

Abstract: A display device and a method of manufacturing the same are disclosed. In one aspect, the display device includes a first substrate, a display unit disposed over the first substrate and a second substrate located over the display unit. The display device also includes a sealing portion disposed outside the display unit and between the first and second substrates, wherein the sealing portion includes a first part extending along a first edge of the first substrate, and wherein the first part comprises an outer side surface that is located on the same surface as an outer side surface of the first substrate. According to embodiments, the display device can reduce a defect rate during manufacturing.
