Abstract: Provided are method and device for managing a memory in a data stream management system (DSMS) of a portable device. The method includes moving data of a selected memory region that has a low priority to a secondary storage and storing a received data stream in the selected memory region.

Abstract: Provided are an apparatus and method for transmitting only sensor data actually used to process a user request among sensor data received from a sensor when communication restarts between a sensor data management device and a sensor data analysis device. Accordingly, the amount of data transmitted to the sensor data analysis device is reduced. The sensor data analysis device may analyze the sensor data received from the sensor data management device to process the user request.

Abstract: A method is provided. The method includes in response to a new query or new input data being input, calculating a required minimum number of cycles per unit time which corresponds to the minimum number of cycles per unit time that is required to process the new query or the new input data, selecting a query to execute first, calculating the number of cycles to be processed during the time period set in advance by multiplying the calculated, required minimum number of cycles per unit time with a time period that is allocated to process the selected query or the input data and is set in advance, and putting a system into a dormant state for a remaining period of time in response to the calculated number of cycles being completely executed within the time period set in advance.

Abstract: The present invention provides an elastase-inhibiting protein isolated ("Guamerin") from a Korean leech, Guameri (Hirudo nipponia) and a process for preparing the same. Guamerin is a protein of a molecular weight of 6,110 Da which is composed of 57 amino acid residues, whose active site is composed of 36-methionine and 37-isoleucine, which retains an inhibiting-activity highly specific to elastase, and which shows stability against heat as well as strong acids and alkalies. Guamerin of the present invention can be applied in the treatment of diseases associated with an excess level of elastase, such as rheumatoid arthritis, emphysema, and psoriasis.
