Abstract: The present invention relates to a language learning system utilizing a component unit more segmented than a phoneme or utilizing various games. The language learning system utilizes several characters as a unit more segmented than a phoneme with respect to morphology learning, and a phoneme as a unit more segmented than a syllable with respect to pronunciation learning. Users can learn a language from the segmented unit to a larger unit such as a syllable, a word and a sentence through the learning system. In addition, the language learning system provides various games to users intending to learn a language by allowing the users to notice positive effects rather than negative effects provided by a game. The games assist users in constructing a phoneme, a syllable, a word, a sentence and the like and assists in connecting a character to a pronunciation, meaning and the like.

Abstract: A gas oven having a gas supplying passage to supply gas to a burner is provided. The gas oven includes an ON/OFF valve to open/close the gas supplying passage, and a flow rate modulating valve connected to the ON/OFF valve in series so as to change the cross-sectional area of a passage, thereby supplying a proper amount of gas to a cooking cavity in response to the change of a cooking area. When a cooking cavity is divided into individual cooking cavities while a divider is mounted, the flow rate modulating valve is open/closed at a smaller opening degree than the maximum operating degree, and thus may be able to prevent a cooking substance from being carbonized in the individual cooking cavities.

Abstract: Provided are an apparatus and method for predicting slab quality including a plurality of meniscus height detecting units prepared in a plurality of region on a top side of a mold receiving molten steel, and detecting a meniscus height of the molten steel, a meniscus flow detecting unit creating a meniscus flow pattern using meniscus heights at the plurality of regions, which are detected by the plurality of meniscus height detecting units, a data storage unit storing the meniscus flow pattern and quality data of a slab produced accordingly and a slab quality predicting unit extracting the meniscus flow pattern detected by the meniscus flow detecting unit and consequent slab quality from the data storage unit to predict slab quality.
