In the past decades, effect of near field earthquake on the historical monuments has attracted the attention of researchers. So, many analyses in this regard have been presented. Tunnels as vital arteries play an important role in management after the earthquake crisis. However, digging tunnels and seismic effects of earthquake on the historical monuments have always been a challenge between engineers and historical supporters. So, in a case study, effect of near field earthquake on the historical monument was investigated. For this research, Finite Element Analysis (FEM) in soil environment and soil-structure interaction was used. In Plaxis 2D software, different accelerograms of near field earthquake were applied to the geometric definition. Analysis validations were performed based on the previous numerical studies. Creating a nonlinear relationship with space parameter, time, angular and numerical model outputs was of practical and critical importance. Hence, artificial Neural Network (ANN) was used and two linear layers and Tansig function were considered. Accuracy of the results was approved by the appropriate statistical test. Results of the study showed that buildings near and far from the tunnel had a special seismic behavior. Scattering of seismic waves on the underground tunnels on the adjacent buildings was influenced by their distance from the tunnel. Finally, a static test expressed optimal convergence of neural network and Plaxis.

The present study examines the connections and effects of these historical events on South Korea's education system. The research seeks to illuminate private education's complex history and the complex factors that have shaped it by examining these historical trajectories. After the Korean War in the mid-20th century, South Korea went from agrarian to industrial, which shaped private education. Unparalleled economic growth in the 1960s and 1980s altered schooling. South Korea quickly became an industrial powerhouse, and education became crucial for families seeking socioeconomic advancement. The growing middle class, believing education was the key to prosperity, demanded more extra education. South Korean private education's fourth major event occurred during the socioeconomic upheavals of the 1960s-1980s. Prior studies explain how the fast transition from agrarian to industrial society made schooling essential for families seeking upward mobility. Due to the demand for extra education, private tutoring and specialist hagwons flourished. In summary, this study insists that the effects of historical events on South Korean private education demonstrate the interconnection of cultural, economic, and sociological aspects. Educational practitioners must comprehend the historical backdrop, recognize the lasting impact of past events, and use literature-based tools to navigate this complex landscape.

Historical cost data estimating system has been introduced since 2004 in the construction industry. Based on contract prices of past projects, this estimating system estimates construction cost according to work types. The Korea Institute of Construction Technology (KICT) announces the historical cost data twice a year annually. The unit price of a small construction project is higher than large construction project due to the increase on production cost per work unit, equipment and labor cost, etc. However, the historical cost data estimating system is applied to project estimation uniformly regardless the construction project's size. This study compared and analyzed the historical cost data of large and small construction project to indicate the problem of historical cost date estimating system. The study derived that the unit price of a small construction project is 21.8% higher than that of large construction project.

Based on clothing prohibition modelling characteristics, this paper studies historical costumes through the traditional Chinese historical dramas of the 'Kang-Qian' heyday during the 'Qing Dynasty'; represents the research object as a representative Chinese historical drama. This paper systematically analyzed the utilization and reflection of royal women clothing prohibition. The results of the study are as follows. The royal women clothing prohibition of this drama shows three aspects of characteristics found in traditional Chinese costume modeling. First, some special colors that integrated ancient and modern styles were mainly used in this drama such as champagne color, wine color, and macaron color. Second, it mainly utilized the modelling of modern artificial pigments and floral patterns that are different from Chinese traditional female costumes of the 'Qing Dynasty'. Third, stage costumes for this drama are focused more on using a personality method to reflect the beauty of each actress by the application of individual elements. This study analyzed and studied the clothing prohibition of female costume from to show the traditional Chinese costume prohibition in a Chinese historical drama as well as reveal a few aspects of traditional female costume characteristics in the 'Kang-Qian' heyday during the 'Qing Dynasty'. This study examined traditional female costumes characteristics in modern historical dramas based on different figures and dynasties as well as discussed the factors at a deeper level and from varied aspects.

Radiocarbon and OSL ages of three monogenetic volcanoes inferred to be the last volcanoes on Jeju Island, Korea were determined to identify a volcano described in historical records. The results show that the ages of those volcanoes are roughly <3.8 ka (Songaksan), >4.5 ka (Biyangdo), and <6~7 ka (Ilchulbong). Though our efforts to make a positive match between historical records and volcano-chronological dating were not successful, we make a new suggestion in this paper that two historical records of volcanic activity in 1002 and 1007 A.D. could be interpreted to be the sequential volcanic events from a single monogenetic volcano. In addition, based on a volcanological reinterpretation of historical records, we infer that the volcano described therein is most likely Mt. Songaksan, in Daejeongeup, which had early phreatomagmatic and late magmatic activities after 3.8 ka ago. Furthermore, considering the geopolitical relationship between the Goryeo Dynasty and the Tamna Kingdom, in addition with the culture of the era, this study sheds new light on the possibility that there is a time gap between the actual eruptions and the historical recording of them by ancient people.

Objectives :The purpose of this paper is to evaluate the significance of the 『Joseonbogeonsa』 by examining North Korea's perspective in its documentation of the history of medicine, and to further understand North Korea's perception of Korean Traditional Medicine. Methods : The focus of examination was on the perspective of historical description as shown in the first chapter of the 『Joseonbogeonsa』. Its unique features were made clear through comparison with historical texts of medicine of South Korea such as the 『History of Medicine in Korea』, and the 『History of Korean Medicine』. In order to grasp the current of historical research in North Korea, various Traditional Medicine related dictionaries and academic journals of North Korea along with the 『Joseontongsa』 were examined. Results & Conclusions : The historical views of the 『Joseonbogeonsa』 could be categorized as nation-focused, materialistic, and nationalistic. These are core elements that make up North Korea's self-reliance ideology, which influenced the interpretation of medical facts. While the text is valuable in that it introduced new historical material along with its interpretation, and argued for a more independent development of Traditional Medicine, its limitation of interpreting historical material from a conclusive, pre-determined standpoint cannot be overlooked. The North Korean 'Goryeo Medicine' is defined by its historical nature rather than academic characteristics, and its significance is determined by its clinical efficacy rather than theoretical value.
