Abstract: Disclosed are a method for manufacturing a microcapsule including a fragrance oil, and a microcapsule containing a fragrance oil. In the method for manufacturing a microcapsule including the fragrance oil, there is provided a fragrance oil-containing microcapsule which has an increased distribution of individual primary particles because the aggregation of the primary particles is suppressed even when the microcapsule is manufactured in a large quantity, has a uniform particle shape and excellent surface characteristics, shows an excellent strain recovery capability with respect to external pressure due to the high yield stress, and enables a stable support of the fragrance oil because the collapse of the microcapsule is suppressed.

Abstract: Provided are preparation of a PCM microcapsule in the form of a core-shell having an excellent heat absorption function by using a temperature-controllable phase change material (PCM) as a core material and a biodegradable polymer material as a shell material, and a cooling cosmetic composition for external skin capable of exhibiting a prevention effect of thermal aging using the same. The core-shell PCM microcapsule having an automatic temperature control function according to the present invention is prepared by dissolving a shell material and a single or mixed PCM in a solvent to produce an oil phase polymer solution, dissolving an aqueous polymer to produce an external continuous phase, emulsifying the oil phase polymer solution and the external continuous phase, and removing the external continuous phase and the solvent and carrying out drying.

Abstract: A method for allocating slots for a synchronous Ethernet service in a Residential Ethernet system includes the steps of: receiving requests for synchronous Ethernet services from terminals requiring the synchronous Ethernet services; calculating a number of slots for each synchronous Ethernet service, and allocating slots for each terminal based on the calculated number of slots; transmitting information about the allocated slots through at least one Residential Ethernet switch; and receiving acknowledgement signals from the terminals in response to the allocated slot information and providing the synchronous Ethernet services using the allocated slots.
