The attenuations of peak vertical displacements are studies using a conventional least squeare regression technique for microearthquakes occurred in the Kyungsang Basin southeastern Korea. The regression model applied to bandpass-fitered ground motion data includes parameters to account for geometric spreading anelastic attenuation depending on frequency source size and station site effects. Thirty nine displacement traces obtained by integrating velocity records for six shallow local microearthquakes are used to determine attenuation characteristics in the Basin. The regression result of the peak amplitude data leads to Q(f)=59.9 {{{{ {f }^{0.955 } }} for 1.5Hz$\leq$ f $\leq$ 25 Hz. It appears that the anelastic attenuation in the Kyungsang Basin is greater than that in the Western North America Area.

The most recent shaking experiences have demonstrated that the predictions of the seismic models are not always in agreement with the registered responses, especially in the face of extreme earthquakes. Records collected from 1960 to 2011 at a rock-like site are used to develop a neural network that permits to estimate peak ground accelerations via the magnitude, the focal depth, the site-source distance and a seismogenic zone. The neural model is applied to the 8th and 19th September 2017 events that hit Mexican territory and the obtained results show that the network is flexible enough to work appropriately to various conditions of intensity and sites-sources with remarkably predictive capacity. The neural-attenuation curves are compared with those obtained from Ground Motion Prediction Equations and their performance is assessed for events, in addition to the devastating Mexican events, from Japan, Taiwan, Chile and USA.

Ginseng, a Korean native herb, has been a symbol of mystic cure-all which provides longevity benefits throughout Korean history. According to Chinese historical records, a major source of wild ginseng has been described as Korean peninsula, which is the most suitable ginseng production area, and the Manchu region near Mt. Baekdu and the Maritime Province. Since Tang dynasty period (618-917 CE), Chinese has also called ginseng as "Goryeo Ginseng", which is named after "Goguryeo" (37 BCE-668 CE), an ancient kingdom of Korea, from which they mainly imported the herb as the region was famous for its high quality of ginseng. To date, it refers to Korean ginseng. This study compares the medicinal properties of ginseng as stated in the ancient Korean medical books with the major Korean historical records regarding the usage of ginseng and its symbolism of longevity in everyday life. By contrasting these findings, we tried to figure out how the actual medicinal properties of ginseng and the anticipation of longevity are related. It was confirmed that the expectations about longevity were widely applied to everyday life. In addition, the study investigates the various usage of ginseng as a motive for decorative patterns and as an ingredient for daily products including snacks, health drinks, various types of food, clothing patterns, and so on. Finally, the usage of ginseng ingredients in the cosmetic products fulfilled the desire of Korean people to purchase, showing the aesthetic recognition and medicinal understandings about the herb. These findings suggest that ginseng is an important medicinal agent that not only symbolizes longevity and good health but also has a great influence on the lives of Koreans.

Objectives : We conducted an investigation on 14 cases of brucellosis in Gyeongsangbuk-do during 2003-2004 to understand the source of infection and the transmission routes of brucellosis. Methods : The authors visited the each of the health centers and we examined the patients, their written epidemiologic questionnaire and the occurrence of bovine brucellosis. We visited the patients' living and work areas, and we examined their occupations, the date they developed symptoms, the progress of their symptoms, whether or not they were treated, their current status, whether or not they consumed raw milk and raw meat, and if their work was related to cattle breeding and the related details. We reviewed the results of the blood tests and medical records and we examined the cattle's barn. Results : There were 3 patients in 2003 and 11 patients in 2004. All of their brucella antibody titer exceeded 1:160. The patients' symptoms were fever, myalgia, malaise, chills and an influenza-like illness, but the clinical signs were absent on the medical records. Brucella abortus were cultured from 3 of the patients' blood samples. Conclusions : When the authors discovered the transmission routes, they were divided into 4 different sorts. The first route was related to cattle birth such that patients touched the calves or placentas that were infected with the Brucella species. The second route was related to performing artificial insemination on the cattle and the semen that was used for artificial insemination. The third route was due to the ingestion of raw meat and milk. The last route was due to sexual intercourse between the patients.

For a long time, popular songs have been our source of happiness. They go along with the flow of the generation, allowing them to acquire a significant meaning. Popular songs thus reflect the contemporary society. However, in the study of popular song archives, there has been an interest only in the information of the songs sung by a singer, the type of songs, and the type of singers. Thus, existing popular song archives were not able to reflect the characteristics of the society of the generation when the songs were popular. Therefore, this paper searched for ways by which to archive not only popular songs but also the characteristics of the society during the time when these songs were famous, and suggested a story collection through the methods. These stories reflect the lives of the people and the characteristics of the society during the periods when the songs were popular. Furthermore, these stories go beyond popular songs, making it possible for us to look dimensionally on the society we are affiliated in.

There is a variety of opinions about the first translation activities within the Turkic Empire. It is widely believed that some Buddhist sutras were translated into the Turkic language in the period of Taspar Qagan (572-581). This theory is based on certain arguments: Some Turks practiced Buddhism, Buddhist monks translated sutras in the center of the Turkic Empire, Taspar brought sutras from China and had them translated, and the monarch of Northern Qi had a sutra translated and sent to Taspar. However, in my opinion, these arguments lack credibility. This article, which is based on primary Chinese sources, will question the likelihood of such translation activities having occurred. Some Chinese records for these claims exist: Da Tang Nei Dian Lu (大唐內典錄) and Xu Gao Seng Chuan (續高僧傳) by the Buddhist monk Jinagupta and the records of Hui Lin in Sui Shu (隋書) and Wen Xian Tong Kao (文獻通考). These are known as "primary sources." Secondary sources, namely contemporary history and language studies, such as those in books and articles, must be based on primary sources. It can be seen that claims relating to the first Turkic translation activities at the time of Taspar are mainly derived from secondary sources, and that the arguments in these secondary sources vary. Sometimes researchers make suppositions on the existence of information that is not referred to in primary sources. However, this is not normal practice. If a researcher relies on unknowns for the evidence of information existing, it can cause false information, ideas and anachronisms to be created. It is important that primary sources, such as the Chinese sources mentioned above, be translated correctly in language and history studies. If only a word is mistranslated, very different results may occur. Mistranslating or misinterpreting a primary source allows conclusions to be reached that are not supported by dissemination of information from primary sources. This can mislead experts and result in information that is not correct being considered as being true. As well as helping to prevent such misinterpretations occurring, another aim of this paper is to question the interpretations of the first Turkic translations in contemporary studies on history and language. The origin of such assessments will be explored and the validity of that information will be examined.

Historical records of earthquakes are generally used as a basis to extrapolate the instrumental earthquake catalog in time and space during the probabilistic seismic hazard analysis (PSHA). However, the historical catalogs' input parameters determined through historical descriptions rather than any quantitative measurements are accompanied by considerable uncertainty in PSHA. Therefore, quantitative assessment to verify the historical earthquake parameters is essential for refining the reliability of PSHA. This study presents an approach and its application to constrain reliable ranges of the magnitude and corresponding epicenter of historical earthquakes. First, ranges rather than specific values of ground motion intensities are estimated at multiple locations with distances between each other for selected historical earthquakes by reviewing observed co-seismic natural phenomena, structural damage levels, or felt areas described in their historical records. Based on specific objective criteria, this study selects only one earthquake (July 24, 1643), which is potentially one of the largest historical earthquakes. Then, ground motion simulations are performed for sufficiently broadly distributed epicenters, with a regular grid to prevent one from relying on strong assumptions. Calculated peak ground accelerations and velocities in areas with the historical descriptions on corresponding earthquakes are converted to intensities with an empirical ground motion-intensity conversion equation to compare them with historical descriptions. For the ground motion simulation, ground motion prediction equations and a frequency-wavenumber method are used to consider the effects of possible source mechanisms and stress drop. From these quantitative calculations, reliable ranges of epicenters and magnitudes and the trade-off between them are inferred for the earthquake that can conservatively match the upper and lower boundaries of intensity values from historical descriptions.

To complement the limitations of the public relations method performed currently in archives and serve various users, a new approach to public relations are needed. Recently, as the size of the webtoon market has expanded, public relations using webtoons continues to heighten in enterprises and public institutions. Therefore, this study proposed a method for public relations using brand webtoon as a means of promoting the archives. This study was focused on the National Archives of Korea. Thus, based on the analysis of roles, service, contents, and users of the National Archives of Korea, this study suggested production plans to increase the promotional effect in brand webtoons and strategies such as viral marketing, the brand story strategy, and the one-source, multi-use (OSMU) strategy.

The Divine Bell of King Seongdeok was completed in 771 A.D. It is a true masterpiece both grand in its size and style (height 3.66 m, diameter 2.23 m, thickness 20.3 cm, weight 18.9 ton), illustrating the essence of the Korean bronze culture. However, there are no remaining records about its casting: where the raw material came from, how the materials were mixed and how the bell was casted. The absence of such records has limited the understanding of the bell. This article contains analysis of three samples collected from a protruding part inside of the bell during a safety test for the bell by the Gyeongju National Museum. The main issues are the element composition of the bell, microstructure on the casting time and the source where the raw material came from.
