Abstract: A method and a system for communicating personal health data in a Near Field Communication (NFC) environment are provided. An NFC manager sets control information in an NFC Data Exchange Format (NDEF) for providing synchronized communication of personal health data between the NFC manager and an NFC agent. The control information may include a direction flag, a state flag, sequence identifier field, and request/response flag. The NFC manager writes the NDEF format including the control information and payload data into an NFC tag associated with the NFC agent. Subsequently, the NFC manager reads the NDEF record stored in the NFC tag and determines whether the NDEF record is written into the NFC tag by the NFC agent based on the control information in the read NDEF format. Accordingly, the NFC manager repeats the above mentioned steps if the NDEF record includes payload data of the NFC agent.

Abstract: In a time data display mode, a time data is displayed in at least one display block partially assigned to a touch screen of an electronic device. After the touch gesture or the drag gesture is detected in one of the display block, the current time data in the display block can be replaced with a new time data according to the touch gesture or the drag gesture. The new time data may be a following time data or a previous time data which can be determined according to a location of the touch gesture, or a direction and a distance of the drag gesture. In addition, the extent of a change in the time data may be determined according to duration of the touch gesture or a speed of the drag gesture.

Abstract: A method of purifying an organic material using an ionic liquid according to the present invention includes a sublimation step (S510) of sublimating the organic material containing an impurity, a capturing step (S520) of bringing a sublimated gas of the organic material into contact with the flowing ionic liquid to capture the sublimated gas, and a recrystallization step (S530) of preferentially oversaturating the organic material, which is to be purified, of the sublimated gas, which is captured in the ionic liquid to be dissolved, to thus generate the recrystallized organic material. In the present invention, it is not necessary to perform a process of carrying the sublimated gas, which is generated during the sublimation step, to implement reverse sublimation. Accordingly, there is a merit in that the contamination of a purified sample by an inert carrier gas, which is used in a conventional sublimation purification method, is fundamentally avoided.
