Abstract: Disclosed is an L-shaped bolt fastening structure for upright fastening which is capable of quickly and firmly fixing equipment to a support structure such as a grating plate without changing the installed grating plate. Since a bent portion of an L-shaped bolt includes a locking groove and an upright auxiliary portion, in a state in which the L-shaped bolt is upright, a fixing nut can be fastened. Accordingly, the fixing nut can be easily and quickly coupled, and also a correct coupling posture can be implemented even after the fixing nut is completely tightened. In addition, since a coupling long hole washer that is divided and coupled is added between a bracket and a fixing nut, when the fixing nut is fastened to the L-shaped bolt, the fixing nut can be fastened in a state in which the L-shaped bolt is upright.

Abstract: Provided is an L-shaped bolt fastening structure using a hole guard, which is capable of being installed in holes having various sizes. Since an L-shaped bolt is fastened in a state in which a hole guard is mounted on a lower structure, fastening using the L-shaped bolt is applicable to a steel pad having a large hole or a large long hole or a grating in which holes are damaged and have irregular sizes. Since bolts can be installed in holes having various sizes in one direction using the hole guard and the L-shaped bolt, the L-shaped bolt fastening structure using the hole guard has a wide range of applications in a floor in an industrial site and as a hook hanger or the like of an H-beam structure, a ceiling, or a wall structure of a construction site.

Abstract: Disclosed are a bolt fastening structure which is couplable and releasable at one side and includes a fall prevention washer capable of preventing a bolt from falling, and an anti-vibration device including the same. By using an L-shaped bolt having a bent portion, even without assistance from below a substructure such as a grating plate, an operator above the substructure can install an anti-vibration device on equipment alone. In addition, by using a fall prevention washer coupled to an L-shaped bolt, a bolt can be prevented from falling below a substructure when working on the substructure.

Abstract: Disclosed is a pipe vibration-proof channel capable of preventing vibration generated in a pipe from being transferred to the outside. Here, since a vertical channel connected to a horizontal channel on which the pipe is disposed is disposed to be separated from a structural section steel member, it is possible to prevent the vibration generated in the pipe from being transferred to the structural section steel member. Also, since a vibration-proof unit capable of absorbing the vibration of the pipe is disposed on a pipe fixing portion configured to fix a vibration-proof bracket and the pipe, it is possible to prevent the vibration of the pipe from being transferred to the vertical channel.

Abstract: Disclosed is a structure for preventing vibrations of equipment, which is capable of preventing vibrations generated by equipment disposed in an industrial facility, a bogie, a facility disposed in a clean room, or the like from being transmitted to the outside of the equipment. The vibrations generated by the equipment may be blocked from being transmitted to a steel grating, which is a lower structure, through a wheel by mounting an anti-vibration unit for blocking the vibrations generated by the equipment on the wheel mounted on a lower end of the equipment. In addition, vibrations, which are transmitted through a fixing bolt, of the equipment may be blocked by forming the anti-vibration unit to surround the fixing bolt for fixing the wheel to the equipment.

Abstract: The present disclosure relates to a two-photon probe for in-vivo imaging, having high selectivity for copper(II) ion, and a method for quantitatively estimating copper(II) on (Cu2+) in vivo using the same. The two-photon probe according to the present disclosure can detect intracellular free copper(II) on for a long period of time with a penetration depth greater than 90 ?m in living cells and tissues without the problems of mistargeting and photobleaching and can quantitatively estimate copper(II) on concentration in vivo using the ratio of blue emission intensity at 400-450 nm and red emission intensity at 550-650 nm.

Abstract: The present disclosure relates to a two-photon fluorescent dye for imaging total sulfide in vivo and a method for quantitatively estimating total sulfide concentration in vivo using the same. The two-photon fluorescent dye, which includes a compound of [Chemical Formula 1], can detect hydrosulfide ion and image total sulfide and allows quantitative estimation of total sulfide concentration in vivo.
