Pyunjak is presumed to be Jinwallin who was active in early Chunchu period among five identically called doctors from early Chunchu period to Warring period. The name, Pyunjak, seems to be used as "special local doctor who goes around the country". This reflects the social atmosphere of the time that medical science and art were getting developed from royal household and government centered medicine to civilian-centered medicine.

Jules Henri Poincare was great not only as a mathematician brit also as a philosopher of science. He received many honors for his outstanding research. He was elected to the Academie des Sciences in 1887 and was elected President of tile Academy in 1906. In 1908 he was elected to the Academie Francaise and was elected director in the year of his death. The Poincare Conjecture was selected Millennium Prize Problems fly The Clay Mathematics Institute of Cambridge, Massachusetts(CMI). The Board of Directors of CMI have designated a $1 million prize fund for the solution to his problem. In this paper, Poincare's major works, his life, his philosophy and the Poincare Conjecture are given.

This study makes SoGanEum(疎肝飮), which is included in YoYak(要略) [JangBuPyoBonHeoSil MaekYakChongBang (臟腑標本虛實脈藥摠方)], its object. It elucidates the origin of this prescription from Chinese medical texts, and examines the characteristics shown in the process of reception through Joseon's exemplary medical texts.

Mathematical induction is one of the deductive methods used for proving mathematical theorems, and also used as an inductive method for investigating and discovering patterns and mathematical formula. Proper understanding of the mathematical induction provides an understanding of deductive logic and inductive logic and helps the developments of algorithm and data science including artificial intelligence. We look at the origin of mathematical induction and its usage and educational aspects.

Spherical trigonometry refers to the geometry related to spherical triangles. It has been an important tool for studying astronomy since ancient times. In trigonometry, concepts such as trigonometric functions naturally emerge from the relationship between arcs and chords of a circle. In this paper, we briefly examine the origin of spherical trigonometry. To introduce the basics of spherical trigonometry, we present fundamental and important theorems such as Menelaus's theorem, the law of sines and the law of cosines on a sphere, along with their proofs. Furthermore, we discuss the educational value and potential applications of spherical trigonometry.

Traditional Asian medicine has an extensive evidence base built upon thousands of years of experience within Asia, of curing various diseases. Only recently, within the past two centuries, have modern medical scientists developed interest in traditional Asian medicine. Asian Medicine seems to be regarded only as an adjunctive medicine and viewed as alargely un-proven alternative medicine to complement western medicine, used in some cases to establish a new paradigm of "integrative medicine". This article reviews how Korean herbal cosmetics emerged by applying traditional Asian medicine to the science of cosmetics. The characteristics of Korean herbal cosmetics are examined through examples of history, concepts and traditions. With the advancements in biotechnology, studies are now being conducted on the dermatological effects and processing methods of herbal ingredients, including ginseng. The authors explain the current research on the identification on the active ingredients of herbs, extraction methods, and bio-processing of ingredients to improve the biological efficacies of herbs on the skin. A summary of studies focused on modern reinterpretations of ageing theories, such as 'Seven year aging cycle', are provided. In conclusion, the development of Korean cosmetics products are based on the accumulated knowledge of thousands of years of experience including; 1) practical heritage of traditional Asian medicines such as Donguibogam; 2) excellent medicinal plants, such as ginseng, which are native to Korea; and 3) innovative attempts to modernize materials, processes, and principles.

This introduction is both a statement of a research problem and an account of the first research results for its solution. As more historical databases come online and overlap in coverage, we need to discuss the two main issues that prevent 'big' results from emerging so far. Firstly, historical data are seen by computer science people as unstructured, that is, historical records cannot be easily decomposed into unambiguous fields, like in population (birth and death records) and taxation data. Secondly, machine-learning tools developed for structured data cannot be applied as they are for historical research. We propose a complex network, narrative-driven approach to mining historical databases. In such a time-integrated network obtained by overlaying records from historical databases, the nodes are actors, while thelinks are actions. In the case study that we present (the world as seen from Venice, 1205-1533), the actors are governments, while the actions are limited to war, trade, and treaty to keep the case study tractable. We then identify key periods, key events, and hence key actors, key locations through a time-resolved examination of the actions. This tool allows historians to deal with historical data issues (e.g., source provenance identification, event validation, trade-conflict-diplomacy relationships, etc.). On a higher level, this automatic extraction of key narratives from a historical database allows historians to formulate hypotheses on the courses of history, and also allow them to test these hypotheses in other actions or in additional data sets. Our vision is that this narrative-driven analysis of historical data can lead to the development of multiple scale agent-based models, which can be simulated on a computer to generate ensembles of counterfactual histories that would deepen our understanding of how our actual history developed the way it did. The generation of such narratives, automatically and in a scalable way, will revolutionize the practice of history as a discipline, because historical knowledge, that is the treasure of human experiences (i.e. the heritage of the world), will become what might be inherited by machine learning algorithms and used in smart cities to highlight and explain present ties and illustrate potential future scenarios and visionarios.

비교적 새로운 역사 분야라는 이유로 또한 다양한 인공물과 그 디자인과 제조, 유통과정에서 비롯되는 주제의 다양성에 따라 디자인사 연구는 상당히 도전적인 분야로 인식되고 있다. 그러나 같은 이유로 디자인사는 스스로 연구의 한계와 난점을 드러내고 있다. 사료의 무한정한 다양성도 문제로 들 수 있다. 근대적 생산기술의 도입에 따라 디자인 대상으로서 인공물의 증가는 생물 다양성의 수백 배를 넘었으며 여전히 기하급수적 증가 일로에 있다. 이는 디자인 역사가가 이 모든 것들을 다루기에는 현실적으로 불가능함을 뜻한다. 둘째, 이러한 인공물의 엄청난 증폭 현상은 최근 170년간의 특수한 현상으로서 이 기간을 하나의 역사 연구 단위로 보기에는 너무 짧고, 또한 현재에도 진행 중이기 때문에 수평 비교를 위한 거시적 안목의 설정이 불가능하다는 것이다. 따라서 이에 대한 객관적인 역사 평가 역시 내리기 어렵다는 점이다. 셋째, 디자인사의 연구 대상인 ‘디자인은 많은 경우 분야와 대상을 동시에 나타내어 그 구분이 어렵다. 즉 디자인은 디자인 행위, 혹은 디자인제(작)품 등의 뜻으로 복합적으로 쓰임으로써 디자인사가 정교히 서술할 만한 주제로 정리되지 못하고 있다. 본 연구는 이런 문제 의식에 기초하여 우리나라에 간행된 여러 디자인사 연구서를 비교 검토함으로써 역사 연구 일반의 체계적 기술을 위한 기초를 마련하고자 한다.
