    Abstract: A hard panel of wall and floor structures for reducing floor impact sound according to example embodiments includes patterned layer having different density and elastic modulus form a base layer. A transmission path of an acoustic wave may be changed in a lateral direction by passing the patterned layer and the sound energy is dissipated by the refection, refraction, and cancellation of the acoustic wave. Thus, a noise is reduced.The hard panel of the wall and floor structures according to example embodiments is effectively reduces the light and heavy impact sounds. In addition, the hard panel is formed by at least one patterned layer to refract and reflect the acoustic wave such that the floor noise may be effectively dissipated. The hard panel is further includes the sound absorbing material to absorb the noise passing through the hard panel such that the floor noise can be effectively reduced.

    Abstract: For wireless power transfer, an energy field is formed by a power transmitter in a space near a transmission coil to provide a transmission power in the space of the energy field. A transferred power is receiver by a power receiver through a reception coil in the space of the energy field. An amount of the transferred power is reduced by the power receiver by performing a regulating operation using a switching frequency when the transferred power is excessive. The power transmitter detects a switching frequency signal having the switching frequency that is induced in the transmission coil when the power receiver performs the regulating operation. The power transmitter controls adjustment of the transmission power in response to the detection of the switching frequency signal. The transmission power is adjusted without a data communication for adjustment of the transmission power between the power transmitter and the power receiver.

    Abstract: The present invention relates to a method for fine-tuning gene expression levels using a synthetic regulatory sRNA in a prokaryotic cell. The present invention can simultaneously, easily, and quickly apply various target gene combinations to various strains without gene deletion through the synthetic regulatory sRNA for regulating gene expression and is therefore very suitable for measuring the metabolizability of each strain and selecting an optimum strain. In addition, the method has the advantages of easily and quickly selecting a target gene for the inhibition of gene expression and expressing the gene thus selected to a desired degree and thus can be used in producing recombinant strains for the efficient production of various metabolites and establishing a method for the efficient production and is therefore very useful.
