Is the Northern Topography of Orono-Shima Island The Prototype of the Key-Hole Tomb? ~ From Aerial Photography by Drone and Image Analysis by Landsat8 ~
Get PDFapplication/pdfOrono-shima Island is a remote Island in the Tsushima Strait, it is 4.3km around. Since ancient times, it has been a landmark when crossing from the Korean Peninsula to Japanese archipelago via Tsushima Island and Iki Island. However, large-scale ruins and burial mounds are not known on Orono-shima Island until now. The author has conducted various surveys of Koro Island and found the possibility that this island was an important island in ancient times. As a result of ground survey, the author discovered a topography like keyhole tomb which is a characteristic Japanese burial mound, on the northern cape of the island. It could be up to 150m in size, one of the largest around Kyusyu Island. There is no burial mound comparable to this on a remote island in Japan. Therefore, we created a 3D image using a drone Laser and hand Laser surveying of this terrain and we compared the results with another keyhole tomb. We asked archaeologists to judge the results. He stated that this could be considered an artificial structure and that excavation would eventually be necessary. Therefore, we investigated in detail the sites that could be candidates for excavation. In addition, we analyzed the image of infrared radiation of Orono-shima Island took by Landsat8. In conclusion, it was speculated that this topography was the prototype of the oldest type of keyhole cairn tomb in Japan. The topography of the northern part of Orono-shima could be regaining the missing link between the cairn on the Korean Peninsula of the first century and the oldest type of keyhole cairn tomb in Japan of the third century.論文(Atticle)departmental bulletin pape

Study on Interatomic potential of M2052 alloy using deep learning
Get PDFapplication/pdfNeural network interatomic potential (NNP) based on deep neural network (DNN) is useful for classical molecular dynamics simulation to obtain accurate vibration damping capacity of high damping alloys. Training data set is generated by ab initio molecular dynamics simulations using pseudo potential and generalized gradient approximation. The NNP for M2052 alloy is generated by the DeePMD-kit. The accuracy of the NNP depends on the number of training steps for deep learning.論文(Atticle)departmental bulletin pape
Law and Policy on the Cyber Supply Chain Security in the United States －117th United States Congress 1st Session－
Get PDFapplication/pdfThe first session of the 117th Congress (2021-2022) was a year of significant change for supply chain security in two ways. The supply chain security community made progress on the revision of NIST SP 800-161, the basic document in the area of supply chain security, and on the rapid development of key policies in response to major security incidents, such as the Colonial Pipeline incident and the Log4j vulnerability incident. On the other hand, there have been the following room to do. The Cybersecurity Maturity Model Certification (CMMC), a framework for mandatory information security measures for contractors in the Department of Defense, was temporarily suspended. And a bill that would establish a new information sharing framework between the public and private sectors regarding security incidents did not reach an agreement. Those may indicate the difficulty of making information security management mandatory, which was originally based on the voluntary approach.論文(Atticle)departmental bulletin pape
The Relationship Between CSR and Financial Performance in China － Empirical Analysis of Tourist Firms in Mixed World Heritage Site using Panel Data －
Get PDFapplication/pdfIn this study, we empirically analyzed the relationship between CSR and financial performance using panel data from 2012 to 2019 for tourism firms at mixed world heritage sites in China from the perspective of sustainable tourism.The results showed that the relationship between CSR and financial performance for these firms was generally positive, although different stakeholders had different effects on financial performance. It is proposed that after the COVID-19 pandemic ends, CSR needs to be further promoted by tourism firms at mixed world heritage sites in China.論文(Atticle)departmental bulletin pape
Effects and Challenges of Developing a Koga City Version of the Bosai-Go! App
Get PDFapplication/pdfIn an effort to prevent regional disasters in Koga City in Fukuoka Prefecture, in this study we developed a location-based smartphone application that is a Koga City version of the Bosai-Go! app. Based on gamification, players are provided with various regional hazard maps through their smartphone that allow them to score points from visits to specific sites, such as hazardous locations and evacuation shelters. Furthermore, we discussed the effects and challenges of developing and using a location-based mobile gaming app that can assist in regional disaster prevention.論文(Atticle)departmental bulletin pape
Why Politicians Show a Smile? : The Case Study of Yoshihide Suga
Get PDFapplication/pdf論文(Article)This paper reveals how a happy expression is used in political interviews. Yoshihide Suga, the former chief cabinet secretary, is the subject of this analysis, exhibits a happy expression in 12 out of 53 questions (22.6%). Happy expressions are classified in three categories: those accompanied by happiness, those which softened the situation, and those that concealed feelings. Politicians attempted to calm down an atmosphere, at times expressing happiness to avoid confrontation with the caster.departmental bulletin pape
