Abstract: The present invention provides an alginic acid-based injectable hydrogel system for labeling an accurate position of a disease lesion and effectively delivering a drug to a target region. The formulation of the present invention can make it easy to locally inject a contrast agent and a drug into a target region while controlling the release rate of the contrast agent or the drug, with the formation of the hydrogel in the injected region. Through the advantages, the labeled position can be accurately determined from images, thereby enhancing the precision of surgical operation, with a minimal incision formed therefor. In addition, when used, the alginic acid-based injectable hydrogel system allows the effective local delivery of a drug to a target region while increasing the long-acting effect of the drug.

Abstract: An electronic device is provided. The electronic device includes a display and a processor. The processor transmits registration information relating to a user's payment means to an external electronic device, receives state information on the payment means, which is generated by the external electronic device using the registration information, from the external electronic device, and displays an indication corresponding to the state information in relation to an object for representing the payment means, through the display.

Abstract: A method of operating an electronic device capable of operating a plurality of execution environments including a first execution environment and a second execution environment is provided. The method includes generating a first authentication value, using a first application executed in the first execution environment, transmitting the first authentication value from the first application through the second execution environment to a second application executed in the first execution environment, transmitting, based on reception of the first authentication value, a second authentication value and a result of authentication of the user from the second application to the first application through the second execution environment, and performing, when the second authentication value corresponds to the first authentication value, payment based on the result of the authentication, using the first application.

Abstract: An electronic device and a payment method are provided. The electronic device includes a first communication circuitry configured to support a first payment function, a second communication circuitry configured to support a second payment function, and a processor configured to operatively connect with each of the first communication circuitry and the second communication circuitry, to output a first user interface (UI) corresponding to a payment request, to obtain payment related information using at least one of the first communication circuitry, the second communication circuitry, or a sensor circuitry operatively connected with the processor, and to output a second UI based on the payment related information.
