A vehicle battery system and a method of controlling charge of a battery in the system are provided. The system includes a first battery module that has a plurality of battery cells connected to each other in series and a second battery module that has a plurality of battery cells connected to each other in series. The second battery module is connected to the first battery module in series. A controller then monitors a state of charge of each of the first and second battery modules, such that when the state of charge of one of the first and second battery modules is less than a predetermined level, the controller performs active cell balancing between the battery cells of the first battery module and the battery cells of the second battery module.

The present invention relates to a composition for preventing or treating respiratory diseases, and more particularly, to a pharmaceutical composition, and to a health food, comprising extracts of herbal mixtures or fermented products thereof having lactic acid bacteria as effective ingredients for preventing or treating respiratory diseases, wherein the herbal mixtures comprise:, Radix glycyrrhizae, Flos Lonicerae, Angelicae Gigantis radix,, Saposhnikoviae radix,, Forsythiae fructus,, Herba epimedii, ginseng, Lithospermi radix, Sanguisorbae radix, Cnidii rhizoma, Scrophulariae radix, and Polygoni cuspidati radix. The herbal extracts or fermented products thereof having lactic acid bacteria exhibit the effects of significantly lowering an airway resistance value; reducing the numbers of leukocytes, neutrophilic leukocytes, lymphocytes, eosinocytes, and basophil leukocytes to levels similar to that of a normal group; and reducing the infiltration of inflammatory cells and eosinocyte cells near AHR on lung tissues. Therefore, the herbal extracts or fermented products thereof having lactic acid bacteria may be valuably used for the prevention and/or treatment of respiratory diseases such as asthma.

Composition comprising herbal extracts or fermented products thereof having lactic acid bacteria for preventing or treating respiratory diseases

A channel switch control method in a digital multimedia broadcasting receiver is disclosed, wherein discrimination is made as to whether a switch to the erstwhile selected channel has been completed in response to receipt of a channel switch command, and if it is determined that the switch operation to the erstwhile selected channel has not been completed, a switch operation to a newly selected channel in response to the channel switch command is delayed until the switch operation to the erstwhile-selected channel is completed and then the channel switch operation is performed, whereby an unstable operation can be avoided resulting from receipt of a switch command to the new channel before a screen output operation relative to the erstwhile-selected channel is completed.
