  • In order to increase the production efficiency of the ship and shorten the production cycle, it is important to evaluate the accuracy of the ship components efficiently during the drying cycle. The accuracy control of the block is important for shortening the ship process, reducing the cost, and improving the accuracy of the ship. Some systems have been developed and used mainly in large shipyards, but in some cases, they are measured and managed using conventional measuring instruments such as tape measure and beam, optical instruments as optical equipment, In order to perform accuracy control, these tools and equipment as well as equipment for recording measurement data and paper drawings for measuring the measurement position are inevitably combined. The measured results are managed by the accuracy control system through manual input or recording device. In this case, the measurement result is influenced by the work environment and the skill level of the worker. Also, in the measurement result management side, there are a human error about the lack of the measurement result creation, the lack of the management sheet management, And costs are lost in terms of efficiency due to consumption. The purpose of this study is to improve the working environment in the existing accuracy management process by using the augmented reality technology to visualize the measurement information on the actual block and to obtain the measurement information And a smart management system based on augmented reality that can effectively manage the accuracy management data through interworking with measurement equipment. We confirmed the applicability of the proposed system to the accuracy control through the prototype implementation.

  • The radical scavenging activity measurement system linked with liquid chromatography (LC) is a useful tool for identifying the radical scavenging active compound in a sample composed of numerous compounds such as plant extracts. Using this system, DPPH and ABTS radical scavenging activity were measured on extracts of Ulmus pumila cortex, which is known as an herbal medicine with antioxidant activity. Mass spectrometry (MS) was performed on the identified radical scavenging active compounds to identify the four components estimated to be procyanidin B2, procyanidin B3, catechin-7-O-β-D-apiofuranoside, and catechin-5-O-β-D-apiofuranoside, respectively. In order to compare the relative contents between extract samples, multiple reaction monitoring (MRM) mode analysis conditions were set for the four compounds in order to examine the possibility of comparing the content of radical scavenging active compounds in Ulmus pumila cortex extract using LC-MS/MS. As a result of the relative content comparison, it was found that the higher the ethanol concentration of the extraction solvent, the higher the content of radical scavenging active compounds. As with the results of measuring the radical scavenging activity of each extract, it was confirmed that the content difference of three of the compounds (all except the compound estimated as procyanidin B3) was not significantly observed in the extracts with an ethanol concentration of 50% or more.
