In this paper, an intelligent health monitoring system based on body-centric wireless communications is studied, and implantable antennas are investigated. To design antennas for an intelligent health monitoring system, the effects of the relative permittivity and conductivity of a human body equivalent liquid on an implantable antenna are investigated via electromagnetic analysis. Two types of capsule antennas, an isolated type capsule antenna, and a surface type capsule antenna, are investigated and compared. An inner-layer implantable capsule dipole antenna with the characteristics of both a large effective electrical length and a small transmission loss is proposed. The methodology of the designed capsule antenna that obtains a maximum received power at 500 MHz by changing the internal impedance is also presented.

In this paper, an intelligent health monitoring system based on body-centric wireless communications is studied, and the implantable antenna is investigated. To design the antennas for intelligent health monitoring systems, the electromagnetic near-field distribution of an implantable antenna placed in the alimentary canal of a human body is investigated by a numerical analysis. The electronic field distribution and the transmission factor of an implantable antenna placed in different parts of the human alimentary canal are presented and compared. It is found that the electronic field distribution of the implantable antenna depends on the operating frequency of the antenna and the conductivity distribution of the human body. The transmission characteristics of the electromagnetic wave from the implantable antenna to the outside depending on the frequency, distance, and filling materials of the alimentary canal. The impedance matching of the implantable antenna in different organs is also presented and compared.INDEX TERMS Intelligent body healthcare management, implantable antenna, near-field distribution, transmission characteristic, impedance matching.
This article takes the talent training of culinary professionals in Guangxi secondary vocational and technical colleges as the research object and analyzes the situation of talents in Guangxi's catering industry and preliminary problem-solving strategies. It proposes to build a "double high" talent training model for accurately serving the local modern catering service industry and elaborates on the actual role of governments, schools, enterprises, and industries in joint education. The model links governments, industries, enterprises, and schools, mobilizes various resources, and builds a multi-level "mentorship" applicable to secondary vocational and technical colleges to control the siphonic effect of the surrounding economic development on talents and adapt to the rapidly changing demand for employment in the market.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
