Abstract: An electronic device may measure a user's exercise or other activity and output intuitive information regarding the activity. The electronic device may include a sensor that senses a movement of the electronic device. A processor may determine types of activity states of specified unit times, and determine a specific activity state as a representative activity state of a specified time range based on distribution of the activity states of the specified unit times. The processor may output information corresponding to a determined representative activity state. Short bursts of secondary activity which occur during the specified time range may be omitted in the output information.

Abstract: Disclosed herein is a hair dyeing composition. The composition induces swelling of hair to expand the cortex by the use of arginine, which is a constituent ingredient of hair, and as a result, effectively allows a colorant to infiltrate into the cuticle, thereby increasing the dyeing rate. Therefore, the composition can markedly decrease the dyeing time to 1˜5 minutes from 20˜30 minutes required in conventional hair dyeing compositions. In addition, the combined effects of aloe vera gel, ceramide and hair keratin enables prevention of damage to the hair during dyeing.
