Abstract: The present disclosure relates to a recombinant vector for plant expression system in which expression is increased by a radio frequency. According to the present disclosure, since the recombinant vector for plant expression of the present disclosure significantly increased the expression of the target protein in plants by treatment of an eco-friendly and biologically stable radio frequency, there is an effect of overcoming a low protein expression problem of a method using plant cells while having an advantageous effect capable of replacing a conventional production method using animal cells or microorganisms.

Abstract: One aspect relates to a composition for predicting preterm birth of the pregnant woman comprising an agent for detecting microorganisms of at least one genus selected from the group consisting of the genus Ureaplasma and the genus Prevotella and microorganisms of the genus Lactobacillus in a vaginal fluid sample of the pregnant woman and a method for predicting preterm birth using the same. According to one aspect, if the relative abundance ratio of the detected microorganisms of at least one genus selected from the group consisting of the genus Ureaplasma and the genus Prevotella is higher than that of normal pregnant woman, and the relative abundance ratio of the detected microorganisms of the genus Lactobacillus is lower than that of normal pregnant woman, it is predicted that preterm birth will occur. Therefore, the composition can be usefully used to predict preterm birth in pregnant women.

Abstract: Provided are a server, system, and method for monitoring and rewarding a pet activity by using a metaverse. A pet activity monitoring and rewarding server using a metaverse connected to a pet terminal and a user terminal via a network to receive information of a pet includes a processor and a memory. The processor is configured to receive the information of the pet from the user terminal through the network, store the information of the pet in the memory, create an avatar of the pet in a virtual space to correspond to the information of the pet, update activity information of the avatar by using the information of the pet received from the pet terminal through the network, and provide a reward point to a user account that owns the avatar, based on the activity information of the avatar.

Abstract: Provided are a dye-sensitized solar cell and a method for manufacturing the dye-sensitized solar cell using a carbon nanotube (CNx) doped with nitrogen, wherein the dye-sensitized solar cell using the carbon nanotube (CNx) doped with nitrogen has an improved conductivity and open circuit voltage as compared to those using the carbon nanotube (CNT) and also a high connectivity between a transparent electrode and an oxide semiconductor

Abstract: A semiconductor device capable of suppressing leakage current increased due to an active moat generated when performing a shallow trench isolation process comprising an isolation layer is formed through a shallow trench isolation process in order to obtain a small isolation pitch; and a plurality of gates passing through an active region defined by the isolation layer, wherein at least one gate includes a sub-gate formed at a lateral side of the gate adjacent to a boundary formed between the active region and the isolation layer and having a length longer than lengths of other parts of the gate. Optionally the length of the sub-gate is about double the length of the remaining portion of the gate.
