This study presents a reference model (RM) and the architecture of a cognitive health advisor (CHA) that integrates information with ambient intelligence. By controlling the information using the CHA platform, the reference model can provide various ambient intelligent solutions to a user. Herein, a novel approach to a CHA RM based on evolutional cyber-physical systems is proposed. The objective of the CHA RM is to improve personal health by managing data integration from many devices as well as conduct a new feedback cycle, which includes training and consulting to improve quality of life. The RM can provide an overview of the basis for implementing concrete software architectures. The proposed RM provides a standardized clarification for developers and service designers in the design and implementation process. The CHA RM provides a new approach to developing a digital healthcare model that includes integrated systems, subsystems, and components. New features for chatbots and feedback functions set the position of the conversational interface system to improve human health by integrating information, analytics, and decisions and feedback as an advisor on the CHA platform.

In this paper, we proposed a new boosting device for internal combustion engines using dynamic pressure. The boosting device is inspired by the concept of boost converter in electrical system. The proposed boosting device is composed of a fan blowing air into an intake manifold, a bypass, and a bypass valve. By using the fan and the bypass valve, kinetic energy of a working fluid is translated into pressure energy. Consequently, the intake manifold pressure is increased due to the pressure energy. The feasibility of the proposed boosting device was validated by a commercial 1-D engine model, GT-power.
