Recently, the elderly population has increased rapidly and it is growing interest in health, so the mushrooms are used as a material for functional food, but the Sanghwang mushrooms research related to material production using the techniques for the mass culture that are valuable industrially has yet to be revealed. In this study, mixed fermenting products of curcuma root and the Sanghwang mushrooms were developed as a beverage and food material with a increased ability to inhibit osteoclast differentiation. Bone marrow-derived macrophages(BMMs) derived from bone marrow cells were cultured for 3 d with the absence or presence of receptor activator of NF-κB ligand(RANKL) with increasing concentrations(2-20ug/mL) of mixed fermenting products. The fermentation broths inhibited RANKL-induced osteoclastogenesis in a dose-dependent manner that the formation of multinucleated osteoclast were confirmed by the low tartrate-resistant acid phosphatase(TRAP) activity without inhibiting the growth of bone marrow cells. The fermentation broths was cultured with edible soy and the sterilized solutions showed a brown liquid was charged in case of the beverage bottle. In order to use the bio-mixed fermentation broth as a primary base of the beverage, it is required the sensory evaluation, stability and expiration date.

An analysis of discontinuity of microstrip transmission line, which is used to the microwave integrated circuit implementation, is very important work to be applied the complicated circuit design based on the multiport network and transmission line theory. In this paper, we treat the FDTD technique that encompasses the electromagnetic modeling, simulation, and analysis of the electromagnetic responses of the complex systems to various electromagnetic stimuli. It provides a understanding of the circuit response that allows for the better design or modification of the low pass circuit. And also, the simulation conditions to apply the FDTD method are proposed for the microstrip circuit design with multistep discontinuities. The conditions are to definition of the microstrip structure, source feeding waveform, CPML boundary condition and the numerical procedure of electromagnetic wave components. Therefore, the low pass circuits having the step-impedance structure composed of microstrip transmission line are analyzed by the FDTD method and the numerical results are compared with the measurement results in order to determine the accuracy. From the coherent results between the numerics and the measurements, the proposed simulation conditions of FDTD can be usefully used to design and realization of microstrip application circuits with the multistep structure.

The rise in the number of elderly patients and patients with chronic disease has caused an increase in healthcare expenditure; this increase may induce changes from the current treatment-oriented healthcare service to a form of prevention and management-oriented healthcare service. Therefore, the importance of personal health records, which enable patients to manage their own health, is growing. Furthermore, with the evolution of digital devices such as mobile and wearable devices, there is a need for personalized and customized health record platforms and services for preventive medicine. In this study, we analyzed the current implementation of services for mobile-based personal health record applications, based on the results of studies reported to date. A total of 14 published research papers related to personal health records were found. Most of them were produced by universities; the most commonly used mobile operation system was Google’s Android; and the most common service were for cancer, followed by chronic diseases. The results of this study are expected to provide significant implications for implementing personalized services by integrating service models using various personal health devices with patient-centric personal health records.
