  • 자연재해의 크기나 규모는 예년에 비해 크게 증가하고 있다. 이러한 이상기후에 대해 합리적인 대응을 해야 함에도 불구하고, 제한된 계측기록으로 인한 데이터 확보가 어려운 상황이다. 따라서 현재의 재해 데이터를 과거 역사 기록으로부터 확장하여 획득하고자 많은 연구가 이루어지고 있다. 본 연구에서는 조선의 홍수기록을 찾아 조사하고 합리적인 방법으로 이를 분석하여 이를 극치수문 연구에 다양하게 활용될 수 있도록 조선왕조실록과 증보문헌비고의 홍수기록 자료를 획득하고 이를 정리, 분석 하였다. 조선왕조실에 기록된 479건의 기록과 증보문헌비고의 143건의 홍수기록을 통계적으로 분석하여 보고자 한다.

  • Purpose: This paper analyzed the historical origins of the Qi concept and assesses its possible contribution to the development of complementary therapy and new nursing practices. Methods: In order to clarify the Qi concept measure its theoretical/clinical potentials, this study analyzed both historical data and experimental research that adopt and apply the concept. These include modern/contemporary research measuring its effects in promoting mental and physical health. Using the method of cross-cultural comparison, this study analyzed diverse approaches to the Qi concept and sought to find common features among the approaches. Results: A historical, cross-cultural analysis revealed several fundamental similarities between Qi theories that have developed in the east and the holistic concepts that have evolved in the western traditions. Especially, the analysis of the more recent research on the Qi concept shows ample possibilities of its future contributions to the development of new diagnostic applications and the promotion of overall human health. Conclusion: The historical study of the Qi concept found some key common factors in the diverse philosophical traditions in the east and the west. Considering the growing popularity of complementary therapy among health professionals and the general public, the Qi concept and its clinical applications are expected to promote human health. In this context, this research contributes to developing new nursing practices based on the concept by clarifying its philosophical origins and theoretical backgrounds.

  • There are many factors that affect the wind speed. In addition, the randomness of wind speed also leads to low prediction accuracy for wind speed. According to this situation, this paper constructs the short-time forecasting model based on the least squares support vector machines (LSSVM) to forecast the wind speed. The basis of the model used in this paper is support vector regression (SVR), which is used to calculate the regression relationships between the historical data and forecasting data of wind speed. In order to improve the forecast precision, historical data is clustered by cluster analysis so that the historical data whose changing trend is similar with the forecasting data can be filtered out. The filtered historical data is used as the training samples for SVR and the parameters would be optimized by particle swarm optimization (PSO). The forecasting model is tested by actual data and the forecast precision is more accurate than the industry standards. The results prove the feasibility and reliability of the model.

  • Retro fashion is emerging among young people as an approach to discovering a new meaning in Korea's historical culture. Research on Korea's unique retro fashion culture is required because there is no research on retro fashion culture based on Korea's historical background. Therefore, this study examined how retro fashion culture has progressed based on Korea's historical background from a nostalgic perspective. All retro-related newspaper articles from 1950 to 2020 were collected, and content analysis was conducted for each semantic unit. The results revealed that personal nostalgia is based on personal experience and is extending to younger generations. In terms of nostalgia in interpersonal relationships, the younger generation reinterpreted the fashion culture of the older generation after the 2010s. In terms of vicarious nostalgia, a retro culture reminiscent of the 1990s with a background in economic development and consumption culture appeared after 2012. The youth culture and university culture of the 1970s and 1980s were reinterpreted as street fashion. Since the late 2010s, the younger generation has been exhibiting cultural nostalgia, believing that the historical Korean culture is not outdated but has a unique heritage formed during the modernization process. Symbolic nostalgia appeared in Korean fashion culture during modernization.

  • The high seismic risk has once again revealed in Türkiye with two major earthquakes that occurred on 06.02.2023, which took its place among the most destructive earthquakes in the last century. Totally, 65 earthquakes that occurred in the historical period in Türkiye were taken into account within the scope of this study. The seismic parameters were compared by considering the last two earthquake hazard maps for the epicenters of these earthquakes. Earthquake Intensity (I) of historical earthquakes were converted to Peak Ground Acceleration (PGA) by using suggested relations. Structural analyzes were performed for a sample reinforced-concrete building by using the obtained PGA's and predicted PGA's in the last two earthquake hazard maps. In the structural analysis, two different material groups such as low (C12-S220) and normal (C25-S420) were selected. As the material strength increased, the period value decreased, while the seismic capacity and stiffness increased. It has been determined that there are differences between the measured and proposed seismic risks for some earthquakes, and as a result, there are significant differences between the expected target displacement values from the structures. Therefore, it will not be possible to estimate the damage and to determine the building performance realistically. The main purpose of the study is to reveal whether the earthquake risk is adequately represented on seismic and structural parameters.

  • The paper examines, in the light of current historiography, the recent trends in the application and applicability of the World Historical studies on the Indian Ocean scenario. Calling for the combination of the breadth of the World Historical studies with the analysis of a historical scenario in its specific spatio-temporal context-instead of a synchronic approach-the present study takes a close look at commerce and politics in the western Indian Ocean in the light of an early 14th century Latin Crusade tract, How to Defeat the Saracens by William of Adam (Guillelmus Ade, Tractatus quomodo Sarraceni sunt expugnandi), a Dominican friar. The text offers remarkable insights into the interlocking of the Indian Ocean and the South Asian subcontinent with the Mamluk Sultanate, the Ilkhanid realm and the Crusades. The paper argues for what is now termed as braided and connected histories.

  • The purpose of the present study lies in understanding the historical context as well as regulatory and administrative restraints of records and archival management system of Korea, with the case of Korean Government Archives and Records Service(GARS). Insights gained from the historical analysis of GARS are expected to provide strategies to develop and reinvent GARS so that the national agency could be the basis of reforming Korean archival system in the future. The present study firstly reviews historical context of 1960s and 1970s, during which GARS was established, as well as its role and hierarchical standing in Korean administrative system. Second, its organizational system is analyzed, focusing on the extent of its specialization and organizational independence. Third, the study proposes to develop strategies to reinvent GARS through reinforcing the public records and archives management act(1999).

  • The purpose of this study is to connect the technics and form from ancient to Korea Dynast But in these period there is no buildings remains but paintings, fine arts, and stupas. In the historical materials there are many architectural form and signature revealings, so as a result these analysis, 1)The building showed in paintings of Silla, and Korea Dynasty reflect the architectural style their own Dynasty. 2)In detail, the architecture of Silla and Korea Dynasy was connected with Chinese architectur Liao, Song. But from the 8Century Koreans were succeeded the one of Silla Dynasty and had originility in architectural style. 3)The architectursl style in Silla and Korea Dynasty were very various and very rich content. And we must more serious study of historical materials so that we improve the ancient a middle age of architcture in Korea.
