A status communication device includes a housing, at least one measuring unit, at least one state displaying unit, a transmitting unit, a receiving unit, a data selecting unit, and a state display controlling unit. The at least one measuring unit measures biological data of a user and an ambient state of the housing. The at least one state displaying unit displays a state of the user or the ambient state of the housing. The transmitting unit transmits first measurement-related data to at least one external device. The first measurement-related data is measurement data measured by the measuring unit or data based on the measurement data. The receiving unit receives second measurement-related data from at least one external device. The data selecting unit selects one state corresponding to the second measurement-related data to display with the state displaying unit if the receiving unit receives a plurality of the second measurement-related data within a prescribed interval. The state display controlling unit controls the state displaying unit based on the second measurement-related data selected by the data selecting unit.

A mask pattern designing method capable of achieving the reduction in the increasing OPC processing time, shortening the manufacture TAT of a semiconductor device, and achieving the cost reduction is provided. An OPC (optical proximity correction) process at the time when a cell is singularly arranged is performed to a cell library pattern which forms a basic structure of a semiconductor circuit pattern in advance, and a semiconductor chip is produced using the cell library pattern to which the OPC process has been performed. At this time, since the cell library pattern which has been OPC-processed in advance is influenced by the cell library patterns around it, the correction process thereof is performed to the end portions of the patterns near the cell boundary. As particularly effective OPC correction means, the genetic algorithm is used.

A data compression method uses a template. In the template, the template optimizing is performed by an artificial intelligent technique (such as a genetic algorithm). The artificial intelligent techniqiue is applied to segments defined by diving input data into uniform segment units. The compression method contributes to enhancing the prediction accuracy. The data is compressed using the results of optimization, and a database is updated to improve the compression efficiency and speed of the subsequent processings. By updating a database by using an optimized template, a template for improving the prediction accuracy is obtained quickly without applying any artificial intelligent technique.
