Since most biosignals rely on contact-based measurement, there is still a problem in that it is hard to provide convenience to users by applying them to daily life. In this paper, we present a mobile application for estimating heart rate based on a deep learning model. The proposed application measures heart rate by capturing real-time face images in a non-contact manner. We trained a three-dimensional convolutional neural network to predict photoplethysmography (PPG) from face images. The face images used for training were taken in various movements and situations. To evaluate the performance of the proposed system, we used a pulse oximeter to measure a ground truth PPG. As a result, the deviation of the calculated root means square error between the heart rate from remote PPG measured by the proposed system and the heart rate from the ground truth was about 1.14, showing no significant difference. Our findings suggest that heart rate measurement by mobile applications is accurate enough to help manage health during daily life.

This study reviewed primary care purchasing issues of the Indonesian single-insurer, BPJS-K, in the context of triangular power relations between the government, the insurer, and the providers, and considered its challenges of purchasing as the national single-insurer. Some literature reviews and interviews with Indonesian stakeholders and residents were used to describe the historical and social contexts of Indonesian healthcare and social health insurance systems especially focusing legal and institutional status of BPJS-K and primary care provision and delivery conditions in remote areas. Though BPJS-K directly belongs to the presidential office of Indonesia, it has limited power in terms of purchasing as a single insurer. Mainly it was due to the lack of primary care resources, Ministry of Health's strong power as the regulator and provider, and BPJS-K's powerlessness against monitoring and quality of care assessment. Ambiguous accountability was another issue among the insurer and the Ministry of Health. This created confusions in primary care provision. It is suggested that each agencies' accountability should be obvious in terms of legal, political, and social contexts.

IIoT stands for Industrial Internet of Things used in manufacturing, healthcare, and transportation in networked smart factories. Recently, IIoT's environment requires an automated control system through intelligent cognition to improve efficiency. In particular, IIoT can be applied to automatic calibration of production equipment for improved management in industrial environments. Such automation systems require a wireless network for transmitting industrial data. Self-calibration systems in laser transmission paths using wireless networks can save resources and improve production quality by real-time monitoring and remote control of laser transmission path. In this paper, we propose a wireless networked system for self-calibration of laser equipment that requires a laser transmission path, and we show the results of the prototype evaluation. The self-calibration system of laser equipment measures the coordinates of the laser points with sensors and sends them to the host using the proposed application protocol. We propose a wireless network service for the wired motor controller to align the laser coordinates. Using this wireless network, the host controls the motor by sending a control command of the motor controller in an HTTP message based on the received coordinate values. Finally, we build a prototype system of the proposed design to verify the detection performance and analyze the network performance.
