A battery management system includes a voltage measurement circuit for generating a voltage signal indicating a cell voltage of each of a plurality of battery cells connected in series, and a controller. The controller determines an observation matrix including a plurality of observation voltage vectors indicating a voltage history of each of the plurality of battery cells in a moving window having a predetermined size based on the voltage signal. The controller determines a recovery matrix including a plurality of recovery voltage vectors corresponding to the plurality of observation voltage vectors in a one-to-one relationship. The controller detects an abnormality of each of the plurality of battery cells based on a plurality of absolute error vectors indicating a difference between the plurality of observation voltage vectors and the plurality of recovery voltage vectors.

A pharmaceutical composition includes any of an extract of, a fraction or an active fraction obtained by fractionation thereof with an organic solvent, and a compound separated therefrom as an active ingredient. The extract of, the fraction or the active fraction obtained by fractionation thereof with an organic solvent, or the compound separated therefrom inhibits the expression of MUC5AC induced by TNF-&#x3b1; and the promoter activity in human lung cancer mucosal cells (H292), reduces the number of inflammatory cells in the bronchoalveolar lavage fluid of the chronic obstructive pulmonary disease mouse model, inhibits the production of reactive oxygen species, and reduces the cytokines; and therefore are effective in preventing or treating chronic obstructive pulmonary disease.
