Objectives : There are a lot of food used herb medicine among the people in order to cure diseases. A medicinal gruel is the easiest and most universal among alimmentotherapy. The purpose of this thesis is to understand a medicinal gruel therapy. Methods: I researched the definition, history, ingredients, application and special feature. Result and conclusion : A medicinal gruel therapy is alimmentotherapy for diseases prevent and diseases treatment which get mixed with her medicine and rice, based on oriental medicine theory. A medicinal gruel therapy was put on record in ${\ll}$A historical book${\gg}$. A medicinal gruel therapy can be used in chronic diseases, convalescent stage, assistant treatment for acute disease, disease prevention, aging prevention, diet food and substitute food for breakfast.

In this paper, we introduce data mining techniques for short-term load forecasting (STLF). First, we use the K-mean algorithm to classify historical load data by season into four patterns. Second, we use the k-NN algorithm to divide the classified data into four patterns for Mondays, other weekdays, Saturdays, and Sundays. The classified data are used to develop a time series forecasting model. We then forecast the hourly load on weekdays and weekends, excluding special holidays. The historical load data are used as inputs for load forecasting. We compare our results with the KEPCO hourly record for 2008 and conclude that our approach is effective.

In the latter half of the 1980's, Systematical Western Archival Science theory was introduced in Japan especially, provenance principle which is fundamental theory in arrangement, original order principle and understanding in level of archives groups. However, they just confirmed public records arrangement theory having done in each Prefectural Archives(文書館) in Japan since 1960's and embodied it. Among them, National Archives of Japan(國立公文書館) just followed arrangement method each ministry and office did. And Saitama Prefectural Archives(琦玉縣立文書館) grasped changes of the name of department, class, standard by class and organization and its affairs before public records arrangement. On the one hand, Japan Center for Asian Historical Records(JACAR: アジア歷史資料セン夕-) is attending on public records by web which National Archives of Japan. The Diplomatic Record Office of the Ministry of Foreign Affairs(外務省外交史料館). The National Institute for Defense Studies(NIDS : 防衛廳防衛硏究所) have. JACAR arranged the public records based on provenance principle following arrangement system they have.

In this paper, we analyzed Korean historical records of the periodic comet Halley in three periods (Three Kingdoms, the Goryeo dynasty, and the Joseon dynasty) using various sources such as Samguksagi (History of the Three Kingdoms), Goryeosa (History of the Goryeo Dynasty), and Joseonwangjosillok (Annals of the Joseon Dynasty). To determine the apparition time of the comet at each return, we referred to the works of Kronk. For the Three Kingdoms period, we could not find any record relevant to Halley's comet from Samguksagi. Instead, we examined the suggestion that the phenomenon two Suns appearing on April 1, 760 (in a luni-solar calendar), which is recorded in Samgukyusa (Renaissance of the Three Kingdoms), indicates an appearance of comet Halley during the daytime. In contrast, we found that all the returns of Halley's comet during the Goryeo dynasty are recorded, although some accounts are questioned. In addition, we found that the appearance of Halley's comet in 1145 is also mentioned in a spirit-path stele made in 1178. For the Joseon dynasty period, we found that all the returns of the comet are recorded, as with the Goryeo dynasty, except for the return of 1910, in which the former dynasty fell. In conclusion, we think that this study will be helpful for understanding Korean historical accounts of Halley's comet.

This study collected and analyzed records related to the Asian dust phenomenon in Korean history books. I collected a wide range of records from diverse sources and identified data for analysis. 290 records were selected through this process. These records provide a variety of information including the occurrence time and duration of the phenomenon, other natural phenomenon occurring at the same date, descriptions of the phenomenon, and so on. Reports on, Asian dust in the historical records was not continuous or uniform. However, their appearance in certain months of the year is similar to that observed in modern times. In addition, I collected 90 records showing it that can be largely divided into two viewpoints which they were a natural calamity or an unusual phenomenon. Generally, natural phenomenons in historical books are mostly recorded in viewpoint of unusual phenomenon. Nevertheless, research result verified the record as actual observational data. Consequentially, it also indicates that this data is important for research from a meteorological point of view. I think that the data collected through this study can be helpful to modern meteorological studies related to the Asian dust phenomenon.

This paper presents a structural performance assessment of a historical masonry clock tower both using numerical and experimental process. The numerical assessment includes developing of finite element model with considering different types of soil-structure interaction systems, identifying the numerical dynamic characteristics, finite element model updating procedure, nonlinear time-history analysis and evaluation of seismic performance level. The experimental study involves determining experimental dynamic characteristics using operational modal analysis test method. Through the numerical and experimental processes, the current structural behavior of the masonry clock tower was evaluated. The first five experimental natural frequencies were obtained within 1.479-9.991 Hz. Maximum difference between numerical and experimental natural frequencies, obtained as 20.26%, was reduced to 4.90% by means of the use of updating procedure. According to the results of the nonlinear time-history analysis, maximum displacement was calculated as 0.213 m. The maximum and minimum principal stresses were calculated as 0.20 MPa and 1.40 MPa. In terms of displacement control, the clock tower showed only controlled damage level during the applied earthquake record.

In this paper, we report the analysis of Korean historical records on the periodic Halley's comet according to the period (i.e., the Three Kingdoms, Goryeo Dynasty, and Joseon Dynasty) using various sources such as the Samguksagi (The History of the Three Kingdoms), Goryeosa (The History of the Goryeo Dynasty), and Joseonwangjosillok (The Annals of the Joseon Dynasty). With regards to the apparition time of the comet for each return, we referred to the works of Kronk. For the Three Kingdoms period, we could not find any record relevant to Halley's comet from the Samguksagi. Furthermore, we examined the suggestion that the phenomenon of "two Suns" which appeared on April 1, 760 (in a luni-solar calendar), as recorded in the Samgukyusa (The Legends and History of the Three Kingdoms), indicates an instance of the the daytime appearance of Halley's comet. In contrast with the Three Kingdoms period, we found that all returns of Halley's comet are recorded during the Goryeo Dynasty, although others have questioned some accounts. We also found that the appearance of Halley's comet in 1145 is mentioned in a spirit-path stele made in 1178. For the Joseon Dynasty period, we found that all apparitions of the comet are recorded, as with the Goryeo Dynasty, except for the return of 1910, at which time the former dynasty had fallen. In conclusion, we think that this study will be helpful for understanding Korean historical accounts on Halley's comet.

삼국유사는 한국 역사 연구에 있어 매우 중요한 고전 중 하나이다. 삼국유사는 삼국시대의 야사, 옛 언어, 시가 등이 담겨있는 역사서로서 해방 이후, 많은 번역작업이 이루어져 왔다. 삼국유사에 대해서는 학술적으로 많은 연구가 있어 왔으나, 그동안 많은 내용이 신문, 방송 매체에서 역사 다큐멘터리의 소재로서도 다루어져 왔다. 그러나, 그 내용을 접하는 방법에 있어서는 종전의 매체가 그러했듯이 한 방향의 전달만이 있었을 뿐이었다. 본 연구는 삼국유사를 멀티미디어적인 방법으로 데이터베이스화함으로써 상호작용성을 이용한 정보검색의 새로운 방법을 연구함으로써 학술적 연구의 성과의 보다 효과적인 활용방법을 모색하는데 그 목적이 있다.

China has countless ancient books that contain thousand years of continuously recorded history across every generation. It is essential to organize the ancient cultural literature in order to better communicate. The study of ancient Chinese literature recently has become a subject of priority. Shi-Ji, one of the representative documents, is used for record keeping because of its experience with ancient Chinese historic materials and artifacts. This draft of Shi-ji is based on ancient Chinese research methods with the purpose to explore the character, phonology, syntax, exegesis and collation of historical value.
