There is great enthusiasm among many mathematics educators to seek to understand how mathematical history can be employed to emphasize the usefulness of mathematics and to make it even more useful. This study focused on reviewing the history of mathematics to provide a 'source of insight.' In this study, the reasons for including the history of mathematics in the mathematics curriculum were divided into three domains: cognitive, affective, and sociocultural. Each domain included the followings: mathematical thinking and understanding; development of a positive attitude and increase motivation; and last, humanistic facets and sociocultural experience. At the same time, we need to develope a pedagogical approach that allows educators to use history properly. Furthermore, we must integrate the historical topics into regular curricula including the syllabus historically-informed grounds.

In this paper, I examined the history of Baizu that the Brief History presented. PRC created Baizu as one the 55 ethnic minority nations, as it "nationalized" all the people living within its territorial boundary. And it constructed the narrative of the "ethnic history" of Baizu, while it constructed the grand narrative of the history of the unified, multinational "zhonghua minzu." There are two major problems in the historical narrative of Baizu, thus constructed. First, the genealogy of the ancestors of Baizu constructed by PRC lacks sufficient historical evidence to prove it. Second, the politically-driven ethnic classification project by PRC produced ethnic minority nation, which does not have their own territory and Baizu was one of them. Because of this, the history of Baizu, who historically lived mixed with other ethnic groups together in Yunnan, cannot help but becoming a part of the larger Yunnan history, rather than constituting a history of an ethnic group. Then, what would be a historically sensible way to write a history of ethnic minorities in Yunnan, who have not transformed themselves into a modern nation? What I would like to suggest is, first, to abandon the construction of the history of Baizu as an ethnic group. I also suggest to distinguish Yunnan from China (zhongguo) as a unit of historical writing, and thus to cut the relationship between the Baizu history and the larger history of the unified, multitethnic "zhonghua minzu." The narrative of the Chinese history (history of Zhongguo), which takes the PRC's current territorial boundary as the unit of historical narrative, lacks historical objectivity. Names for historical communities survive, because they have been used by those who have lived in the communities as well as by other historical communities. Members of a certain historical community occupy distinctive historical space and share common historical experience. And their historical experience is mainly informed by political changes that affected the space that the historical community occupies. If one constructs the history of "Yunnan" as a distinctive historical space and community, which could be distinguished from the historical "China" (zhongguo), one may be able to construct the history of the people of Yunnan in its fullest sense.

Ovaries of 21 bitches presented with gynecopathies were surgically removed and histologically examined. Standard histological, as well as immunohistochemical, classification of 193 cystic structures resulted in the classification of 72 cysts of subsurface epithelial structures (SES), 61 follicular cysts (FCs), 38 cystic rete ovarii (CRO), 13 lutein cysts (LCs), and 9 non-classifiable cysts (NCCs). In addition to the histological classification, results were interpreted according to subject medical history, clinical examination outcome, and macroscopic observations during ovariohysterectomy. Dogs with ovarian cysts (OCs) and associated reproductive perturbations were mostly nulliparous, of large breed, and had an average of $9.5{\pm}3$ years. Prolonged or shortened inter-estrus intervals of past heats, however, seemed to be relatively low-risk factors for the development of OCs in dogs. Furthermore, we provide histological observations of a rarely seen canine LC including a degenerated oocyte in the central cavity.

Information technology improves the efficiency of humanities research. In humanities research, information technology can be used to analyze a given topic or document automatically, facilitate connections to other ideas, and increase our understanding of intellectual history. We suggest a method to identify and automatically analyze the relationships between arguments contained in unstructured data collected from humanities writings such as books, papers, and articles. Our method, which is called history mining, reveals influential relationships between arguments and the philosophers who present them. We utilize several classification algorithms, including a deep learning method. To verify the performance of the methodology proposed in this paper, empiricists and rationalism - related philosophers were collected from among the philosophical specimens and collected related writings or articles accessible on the internet. The performance of the classification algorithm was measured by Recall, Precision, F-Score and Elapsed Time. DNN, Random Forest, and Ensemble showed better performance than other algorithms. Using the selected classification algorithm, we classified rationalism or empiricism into the writings of specific philosophers, and generated the history map considering the philosopher's year of activity.

Korea follows the Korea standard classification of disease and causes of death according to the ICD(international classification of disease) Oriental medicine began to of officially follow the classification of disease for using the Korean classification of diseases in 1972. The classification of OM(oriental medicine) has changed in shape experiencing two amendments. The largest difficulty was to overcome the different names of diseases between OM and ICD. A one-to-one correspondence of the name of a disease between OM and ICD is impossible So in the primary stage one-to-one and one-to-many correspondence was made. During the first amendment the international disease names were re-classified on the oriental medicine disease name's basis and at the same time the classification of OM was corresponded on a one-to-one basis to the ICD . During the second amendment this changed to many-to-many correspondence . Analyzing the history of classification of OM during the first and second amendments, it was discovered that establishment of the standards of classification, the unification of oriental medical terms, and overcoming the difference of disease names between the OM and ICD is necessary Also th classification and standardazation of OM must not stop as a single round. It must go on for a long time. The hosts of this project Korean oriental medical society and AKOM(association of korean oriental medicine) need to build a independant department which will supervise the classification project and monitor any problems to come up. Also a route through which suggestions can be taken in and new solutions can be brought up needs to be secured and an atmosphere in which studies can take place about the basis of classifications needs to be developed.

In an online shopping site or offline store, products purchased by each customer over time form the purchase history of the customer. Also, in most retailers, products have a product taxonomy, which represents a hierarchical classification of products. Considering the product taxonomy, the lower the level of the category to which two products both belong, the more similar the two products. However, there has been little work on similarity measures for sequences considering a hierarchical classification of elements. In this paper, we propose new similarity measures for purchase histories considering not only the purchase order of products but also the hierarchical classification of products. Unlike the existing methods, where the similarity between two elements in sequences is only 0 or 1 depending on whether two elements are the same or not, the proposed method can assign any real number between 0 and 1 considering the hierarchical classification of elements. We apply this idea to extend three existing representative similarity measures for sequences. We also propose an efficient computation method for the proposed similarity measures. Through various experiments, we show that the proposed method can measure the similarity between purchase histories very effectively and efficiently.

The core version of UDC(Universal Decimal Classification) is available in an electronic form called MRF(Master Reference File) which supports the maintenance of the quality of the scheme as a working tool for the UDCC(UDC Consortium) by annual reviewing its content and initiating revisions and extensions. In this paper, we discuss outcomes of our in-depth analysis of the geography, biography and history disciplines in UDC focused on the its evolutions and characteristics, including the common auxiliaries of place, the common auxiliaries of time and the common auxiliaries of race, ethnic grouping and nationality. Based on the in-depth analysis, we suggested some ideas which can be applied into the history class of KDC(Korean Decimal Classification). In particular, its principle of combination methods in the history of individual regions, the way of its assignment of physical geography and human geography in the same division, the possibilities of the extension of the table of geographical division and the adaptation of the table of chronological division in KDC.

Objective : This study is about how the theory on ten kinds of prescriptions has been developed and how it has been applied for in prescription books and clinical texts. Methods : I made a comparison of this theory in prescriptions books and clinical texts. After it, I investigated the developing history based on it. Results and Conclusion : This theory had been used for classification of not prescription but herb, until Cho Gil(趙佶) and Seong Mugi(成無已) enlarged its meanings. The first mention about it was made by Jin Janggi(陳藏器). Yu Wanso(劉完素) gave it more definite meanings by showing prescription examples than before. Jang Jahwa(張子和) corrected what Yu Wanso explained. Besides, someone for example, Gu Jongseok(寇宗奭), Mok Huiong(繆希雍), Seo Chunbo(徐春甫), and so on added some kinds of prescription.
