Pulse oximetry data such as saturation of peripheral oxygen (SpO2) and pulse rate are vital signals for early diagnosis of heart disease. Therefore, various pulse oximeters have been developed continuously. However, some of the existing pulse oximeters are not equipped with communication capabilities, and consequently, the continuous monitoring of patient health is restricted. Moreover, even though certain oximeters have been built as network models, they focus on exchanging only pulse oximetry data, and they do not provide sufficient device management functions. In this paper, we propose an advanced pulse oximetry system for remote monitoring and management. The system consists of a networked pulse oximeter and a personal monitoring server. The proposed pulse oximeter measures a patient's pulse oximetry data and transmits the data to the personal monitoring server. The personal monitoring server then analyzes the received data and displays the results to the patient. Furthermore, for device management purposes, operational errors that occur in the pulse oximeter are reported to the personal monitoring server, and the system configurations of the pulse oximeter, such as thresholds and measurement targets, are modified by the server. We verify that the proposed pulse oximetry system operates efficiently and that it is appropriate for monitoring and managing a pulse oximeter in real time.

As the numbers of traveler increases and BYOD culture spreads, this study developed a smart key system using NFC of smart phone that allows people to use their smart phones to easily make room reservations and enter their rooms without separate keys. This system attempts to resolve difficulties experienced while managing and utilizing accommodations from a distance, difficulties experienced when users lose keys or forget their password and in communication between users and managers. The test results in the actual locker management, it is very useful to utilize of the locker administration in the various place, as well as useful accommodation. The implemented smart key system has the benefit to control the Doorlock without a secret number.
