The present invention relates to a nucleic acid molecule capable of controlling innate immunity by RNA and, more specifically, to a short duplex hairpin RNA (sdhRNA) that binds to protein kinase R (PKR), which is activated upon recognition of RNA, thereby inhibiting the activity of PKR and suppressing PKR-mediated innate immunity and which, when introduced into the 3'-UTR of mRNA, can increase the expression level of an antigen. The sdhRNA motif according to the present invention inhibits the activity of protein kinase R (PKR) by binding to PKR activated by recognizing RNA. Therefore, when administered into cells in combination with exogenous RNA or as an insert into the 3'-UTR of mRNA, the sdhRNA motif exhibits the effect of reducing RNA-indued PKR activation, mitigating RNA-induced cell death, and downregulating the expression of interferon-stimulated gene (ISG) as well as improving the expression efficiency of a protein encoded by the mRNA. With the effects, the motif is applied to various RNA-based uses, for example, vaccines, in vivo/ex vivo gene therapeutic agents, and the like.

An existing method for measuring the location of a communication device using an FMCW radar uses a frequency carried by the communication device, and uses a method for calculating the difference between the frequency of a transmission signal of the FMCW radar and the frequency of a carrier wave carried by the communication device. However, in the process of identifying the frequency difference, the frequency of the reciprocal of the unit chirp time length is only measured as the resolution, and an accurate frequency is unable to be measured. In order to solve the above problem, the invention of the present application transmits a continuous chirp signal from the FMCW radar by using the FMCW radar and a frequency modulation tag, calculates an intermediate signal (IF) which is the difference in frequency between signals received at the same time, and demodulates an accurate modulation frequency f_m, thereby quickly and accurately measuring the distance between the FMCW radar and the communication device.
