Abstract: The present disclosure relates to a pre-5th-Generation (5G) or 5G communication system to be provided for supporting higher data rates Beyond 4th-Generation (4G) communication system such as Long Term Evolution (LTE). According to various embodiments, a relay terminal comprises at least one transicever and at least one processor operativley coupeld to the at least one transicever. The at least one processor is configured to broadcast a search message, receive information for indicating at least one relay terminal of a plurality of relay terminals having transmitted search messages to the remote UE, identify a second relay terminal among the at least one relay terminal, and transmit identification information for the identified second relay terminal to the remote terminal.

Abstract: Disclosed herein is a latch circuit capable of preventing an output failure caused due to simultaneous transition of a control signal and an input signal. The latch circuit according to the present invention generates a separate control adjustment signal CTR using the control signal Control and the input signal In and uses the control adjustment signal CTR, instead of the control signal for a latch operation. Accordingly, when the control signal and the input signal transition at the same time, the control adjustment signal is processed not to transition during a transition interval of the input signal, thereby preventing a metastability problem that occurred in the existing latch circuit.

Abstract: Provided herein is a fish robot. The fish robot includes a head unit corresponding to head portion of a fish; a driving unit coupled to the head unit to generate driving force by sinusoidal swimming movement; a waterproof cover coupled to the head unit with elasticity in which the driving unit being inserted to be sealed; and a body unit coupled to the head unit with elasticity corresponding to body portion of the fish in which the waterproof cover being inserted to be supported.

Abstract: Disclosed herein is a forged seal imprint checking method which includes a step ST-101 of generating a reference seal imprint from a genuine seal (ST-110) and a step ST-121 of comparing a compared seal imprints with the reference seal imprint to calculate characteristic values of the compared seal imprint with respect to the reference seal imprint (ST-140). According to experimental results, forged seal imprints obtained by seals forged by etching a zinc plate or a resin plate can be recognized and forged seal imprints generated by seals forged through computer copy can be also recognized. Accordingly, an objective basis on which it can be determined whether seal imprints on documents are forged in civil and criminal cases can be provided to prevent errors which may be generated when seal imprints are inspected with the naked eyes or microscopes.

Abstract: A photocurable pressure-sensitive adhesive (PSA) composition includes an acrylic PSA binder, the acrylic PSA binder including at least one fluoro group in an amount of about 6 mol % to about 30 mol % based on a total amount of the acrylic PSA binder, a thermal curing agent, and a photoinitiator.

Abstract: A composite polyamide reverse osmosis membrane and method of producing same. In a preferred embodiment, the membrane is made by coating a porous polysulfone support with an aqueous solution containing 2 wt % m-phenylenediamine (MPD), and 0.1 wt % di(ethylene glycol) hexyl methyl ether. Next, the excess solution is removed, and the coated support is dipped in 0.1 wt % organic solvent solution of trimesoyl chloride (TMC) in a mixture of alkanes having from 8 to 12 carbon atoms. After draining the TMC solution off, the resulting composite membrane is air dried and then rinsed in a basic aqueous solution. The resultant membrane exhibits a flux of 21.3 gfd and a salt rejection of 98.9% when used at 225 psi for an aqueous solution containing 2000 ppm of NaCl.
