Abstract: A semiconductor memory device includes a memory cell array, an error correction code (ECC) circuit, a fault address register, a scrubbing control circuit and a control logic circuit. The memory cell array includes memory cell rows. The scrubbing control circuit generates scrubbing addresses based on refresh operations performed on the memory cell array. The control logic circuit controls the ECC circuit such that the ECC circuit performs an error detection operation on a plurality of sub-pages in a first memory cell row to count a number of error occurrences, and determines whether to correct a codeword in which an error is detected based on the number of error occurrences. An uncorrected or corrected codeword is written back, and a row address of the first memory cell row may be stored in the fault address register as a row fault address based on the number of error occurrences.

Abstract: Disclosed is a method of preparing fatty acid alkyl ester sulfonate using coffee oil. The fatty acid alkyl ester sulfonate prepared using the coffee-derived oil has superior cleaning capacity compared to commercially available alkylbenzene sulfonate (LAS). In addition, a detergent composition containing fatty acid alkyl ester sulfonate prepared using coffee-derived oil exhibits cleaning capacity equal to or higher than that of a detergent containing fatty acid alkyl ester sulfonate prepared using palm oil and can be used as an alternative to palm oil.

Abstract: The present invention provides a laundry sheet wherein one or more component selected from a group consisting of a builder, an enzyme, a bleaching agent and a bleach activator is contained as a granule in a laundry film prepared using a laundry detergent component and a film-forming water-soluble polymer. The laundry sheet of the present invention completely dissolves in water and thus does not need to be removed after laundering. In addition, the laundry sheet of the present invention has superior cleaning performance, is convenient to use and has superior storage stability.

Abstract: The present invention provides a laundry sheet in which at least one laundry component is distributed inside a matrix formed from a water-soluble polymer, which is a polyvinyl alcohol or a polyvinyl alcohol-based polymer, and the laundry sheet has (i) a foamability of 0.5-0.9 (g/cm3) or (ii) a drape stiffness of 3.5-7.5 cm.

Abstract: A polymerizable composition, polymer capsules and a fabric softener composition are provided. The fabric softener composition includes polymer capsules in which cationic groups are introduced on the surfaces thereof, so that early release of a fragrance can be suppressed and aromas can be generated depending on rupture of a shell material of the polymer capsules by light friction at certain times. In addition, the polymer capsules have high adhesion to fibers and are not attached to fibers during washing to minimize the discharged fragrance, so that sufficient aromas can be provided even if a small amount of fragrance is used.

Abstract: The present disclosure provides a method for preparing a microcapsule and a microcapsule prepared thereby capable of selective release of oils and preventing volatilization of oils while maintaining long-term performance by improving storage stability of the oil contained in the capsule.

Abstract: An apparatus is configured to allocate an IDentification (ID) cell to avoid duplication of a preamble Pseudo Noise (PN) code in a broadband wireless communication system. The apparatus selects one sector inside the system. A temporary ID cell for the selected sector is selected. Whether an ID cell of a sector to which an ID cell has been already allocated inside a minimum unit group for ID cell allocation is the same as the temporary ID cell is determined. Whether PN codes of sectors inside a neighbor list of the selected sector are the same as temporary PN codes determined using the temporary ID cell are determined. When the temporary ID cell is not duplicated and the temporary PN codes are not duplicated, the selected temporary ID cell is allocated as an ID cell of the selected sector.
