In this study, we investigated the reinforcing effects of waveform micropiles in a stratigraphic setting comprising buried soil, weathered soil, and weathered rock. We conducted a series of field load tests and determined that waveform micropiles exhibited sufficient bearing capacity through frictional resistance in the soil layer and demonstrated favorable constructability in conditions with deep bedrock layers. Moreover, the vertical stiffness of waveform micropiles was approximately 2.2 times higher than that of conventional micropiles when subjected to the same design load. Pile group load tests comprising conventional and waveform micropiles showed that micropiles with higher stiffness carried a greater proportion of the load. Although there was no significant difference in the bearing capacity between conventional and waveform micropiles under the same design load, waveform micropiles with higher stiffness showed a load-carrying capacity 1.7 to 3.2 times greater than that of conventional micropiles. These findings suggest that waveform micropiles can be effectively used for foundation reinforcement and reduce the risk of foundation failure when increased loads due to modifications such as expansion remodeling are expected.

Due to recent severe climate change, abnormal weather phenomena, and other factors, the frequency and magnitude of natural disasters are increasing. The need for disaster management using artificial satellites is growing, especially during large-scale disasters due to time and economic constraints. In this study, we have summarized the current status of next-generation medium-sized satellites and microsatellites in operation and under development, as well as trends in satellite imagery analysis techniques using a large volume of satellite imagery driven by the advancement of the space industry. Furthermore, by utilizing satellite imagery, particularly focusing on recent major disasters such as floods, landslides, droughts, and wildfires, we have confirmed how satellite imagery can be employed for damage analysis, thereby establishing its potential for disaster management. Through this study, we have presented satellite development and operational statuses, recent trends in satellite imagery analysis technology, and proposed disaster response strategies that utilize various types of satellite imagery. It was observed that during the stages of disaster progression, the utilization of satellite imagery is more prominent in the response and recovery stages than in the prevention and preparedness stages. In the future, with the availability of diverse imagery, we plan to research the fusion of cutting-edge technologies like artificial intelligence and deep learning, and their applicability for effective disaster management.

The painting group of Late Ming and Early Qing Dynasty is an era of confusion between the orthodox who faithfully cooperated with the Qing Dynasty and the individualist who had a hostile attitude. The country was ruined by these dynasties, and the family left the real world with the suffering of the breakdown and stayed in the mountains.Paldaesanin and Seokdo, the representative Yumin painters, did not form any a sect as a unique expression style for finding a true self.And, through his work, he expressed on madness and oddity through new ideas and composition that he feels misery and anger in his heart. The paintings of these paintings had semi-normative and impromptuous views of nature, which even the self burdened with grief was forgotten.And I expressed my own individuality and originality by forming a simple and free, on madness and oddity art aesthetic. The paintings of these paintings had semi-normative and impromptuous views of nature, which even the self burdened with grief was forgotten.And I expressed my own individuality and originality by forming a simple and free, on madness and oddity art aesthetic. Paldaesanin portrayed a strange figure with a spirit of resistance and a sad and angered emotion, through a unique technique of painting.The content is cynical, satirical, ironic, and on madness and oddity. On the other hand, Seokdo explained "ilhoeg" that the method of writing and the method of writing in "Hwaeolog" agree with each other.This has allowed us to achieve autonomy as a "rule without rules" that goes beyond the existing rules. And he delicately portrayed beauty, desire, and emotion with the use of sensuous brushes and the beauty of the colors.Their unique paintings were later conveyed to yangjupalgoe and led to the flow of paintings in the 18th century.

The Invention Promotion act is one of the acts that have been frequently revised. Such frequent revisions have been pointed out as a major cause of the recent ongoing discussion on the alignment of the Invention Promotion Act. For proper alignment of the Act, diversified perspectives and issues have been discussed. Of them, the talk considering the effect of the 2011 Framework Act on Intellectual Property establishment on the Invention Promotion Act has received increasing attention. In this situation, this paper examined the relationship between the Framework Act and Invention Act with special focus on the relationship between the framework-formed law and an individual act that has existed prior to such a framework act. Based on this analysis, this study examined the alignment goal of the Invention Act. In addition, by studying the relationship between the recently-established framework act and the individual act along with revision case examples thereof, this paper aimed to produce a standard reflecting the legal reality. This study assumed that, although it is difficult to recognize any formal superiority in the Framework Act on Intellectual Property in the present South Korean legal regime, some practical superiority or practical supremacy is still deemed to be acknowledged. Under this assumption, it was found in this study that the Invention Promotion Act would also need to be managed in an appropriate relationship with the Framework Act within the range of such an attitude. Moreover, the structure would need to be reorganized. As discussed partially at the practical level, however, the Invention Promotion Act is an execution act of the Framework Act on Intellectual Property. Furthermore, it is inappropriate to seek to converge the full structures completely, given the limitations of the South Korean legal regime and the fairness balance with other legal cases. It is deemed that, although the provisions of the Framework Act on Intellectual property should be considered at the practical level, the Invention Promotion Act will need to be respected for its legislative purpose in itself.
