Abstract: An adaptive block cache management method and a DBMS applying the same are provided. A DB system according to an exemplary embodiment of the present disclosure includes: a cache configured to temporarily store DB data; a disk configured to permanently store the DB data; and a processor configured to determine whether to operate the cache according to a state of the DB system. Accordingly, a high-speed cache is adaptively managed according to a current state of a DBMS, such that a DB processing speed can be improved.

Abstract: An adaptive cache management method according to access characteristic of a user application in a distributed environment is provided. The adaptive cache management method includes: determining an access pattern of a user application; and determining a cache write policy based on the access pattern. Accordingly, a delay in speed which may occur in an application can be minimized by efficiently using resources established in a distributed environment and using an adaptive policy.

Abstract: An ECG sensing apparatus and a method for removing a baseline drift in the clothing are provided. The ECG sensing apparatus filters ECG signals and filters a baseline drift noise which is caused by human body's motion and breathing. Accordingly, the baseline drift in the sensing apparatus is minimized even if there is a free motion.
