Although research conducted in East Asia has uncovered parasite eggs from ancient toilets or cesspits, data accumulated to date needs to be supplemented by more archaeoparasitological studies. We examined a total of 21 soil samples from a toilet-like structure at the Hwajisan site, a Baekje-period royal villa, in present-day Korea. At least 4 species of helminth eggs, i.e., Trichuris trichiura, Ascaris lumbricoides, Clonorchis sinensis, and Trichuris sp. (or Trichuris vulpis) were detected in 3 sediment samples of the structure that was likely a toilet used by Baekje nobles. The eggs of T. trichiura were found in all 3 samples (no. 1, 4, and 5); and A. lumbricoides eggs were detected in 2 samples (no. 4 and 5). C. sinensis and T. vulpis-like eggs were found in no. 5 sample. From the findings of this study, we can suppose that the soil-transmitted helminths were prevalent in ancient Korean people, including the nobles of Baekje Kingdom during the 5th to 7th century.

Objectives : Many keyboarding staff are required for compositional herb data entry from ancient documents. It's the most difficult thing to build DB. So, we have studied to solve this problem. Methods : We have used Windows 7 and Access2013 for automatic extraction compositional herb in the Taipinghuiminhejijufang(太平惠民和劑局方). First of all, we have made synonyms list of herbs and list of herb volumes notation. And than we have analyzied order of arrangements between names of herb and notations of herb volume. Results : We have analyzied a part of prescriptions in the Taipinghuiminhejijufang(太平惠民和劑局方) (519 prescriptions). After 91 seconds, we can complete automatic extraction of compositional herb from 519 prescriptions. Conclusions : If we can analyzie order of arrangements between names of herb and notations of herb volume, we can automatically extract compositional herb of prescription from ancient documents.

This study has to do with the architectural exchanges between the ancient Korea and China. There are two parts in this paper. The first part is concerned with bibliographical and archeological studies between two regions. The latter part is to compare and syudy the architectural style of china with the architectural style of BAEGJE in those days. At any rate, this paper is related to the first part of them. The most important purpose of this paper is more clearly to inquiry the BAEGJE Architecture. BAEGJE Architecture is the most insufficient in researches of the era of Three Kingdoms' architecture of Korea until now. Because the architectural Matrrials is also the most insufficient condition in Three Kindoms, in order to inquiry the architectural style of BAEGJE clearly, we will be able to get the clue as inquring the relations of the chinese which they exchanged most frequently. The first part of this paper is $appraoc{\sim}ed$ in two methods of the study. One is the biblilographical research and the other is the archeological research. The writer could find that there were many exchage relations in the bibliographocal and archeological fieds, as a result of this study. The writer could confirm that there were nearly coexisting similiar styles of the Architecture.

This Paper discusses the history of the conflicts between synthesis and analysis, from those in heuristic and logic development style in ancient Greek to those in projective geometric methods. The two methods, which originally displayed difference in heuristic, offer the base for the two fields of geometry, the analytic geometry and the synthetic geometry in the 18th century as they originated from the field of geometry. As to the 19th century, they even display antagonistic aspects derived by having other perspectives about the true nature of mathematic but finally lose the reason of conflict as the ancient times when the dialectical sublation of both had been proposed.

In this paper, the wind-induced response of Jiayuguan wooden building (world cultural heritage) in Northwest China was studied. ANSYS finite element software was used to establish four kinds of building models under different working conditions and carry out modal analysis. The simulation results were compared with the field dynamic test results, obtaining the model which reflects the real vibration characteristics of the wooden tower. Time history data of fluctuating wind speed was obtained by MATLAB programming. Time domain method and ANSYS were used to analyze the wind-induced vibration response time history of Jiayuguan wooden building, obtaining the displacement time history curve of the structure. It was suggested that the wind-induced vibration coefficient of Jiayuguan wooden building is 1.76. Through analysis of the performance of the building under equivalent static wind load, the maximum displacement occurs in the three-story wall, gold column and the whole roof area, and the maximum displacement of the building is 5.39 cm. The ratio of the maximum stress value to the allowable value of wood tensile strength is 45 %. The research results can provide reference for the wind resistant design and protection of ancient buildings with similar structure to Jiayuguan wooden tower.

Ginseng was the most revered of the herbs in ancient times in China, Korea, Japan, America. Ginseng was discovered over 5000 years ago in the mountains of Manchuria, China. References to ginseng are found in books dating back more than two millennia. It is revered by the Chinese people as it is considered a herb for everything use and therefore for a wide range of diseases (currently its Latin name derived from the Greek panacea, meanings, that is, for everything). So, it was used exclusively by the Chinese Emperor's, and they were willing to pay the price without problems. Increasing its fame, ginseng brought a flourishing international trade that allowed Korea to supply China with silk and medicines in exchange for wild ginseng and later along with what grows in America.

In spite of the increasing significance on a scale of building measurement unit and its system having been used in many areas of architecture, only a few researchers carried out the studies on a specific period. It is even harder to find a research results dealt in view of architecture. This research gives a focus on different types of scales employed in the ancient buildings and their sites, based on the research results of unit scale or scales found in recent excavations. After the review of literature on the scales widely used in the ancient times and of the various types of scales excavated archeologically, a kind of scale unit system that had been widely and extensively employed throughout the period of 'Three Kingdoms' could be revealed. The scale system is possibly able to be applied to estimate the exact scale of buildings and their sites as well in that era. The research results show that the scale and its system employed in the East and West buildings and their sites of 'Kum-dang' in 'Mi-ruk Sa' temple are different from 'Kokuryo' scale that was believed in to be used in the temple. Contrary to the suggestion by excavation report on the type of scale employed in the buildings their sites, a scale of 29 centimeters, similar to that of Tang, was employed. It was also found that one module consists of three 'Chuk's of 88.8 centimeters. Based on this scale system, we could conclude that three modules of the buildings on the front and two and half modules of them on the sides were explained by this scale and its system.

This study was carrying out research on the geometry of Sulbas${\={u}}$tras as parts of looking for historical roots of oriental mathematics, The Sulbas${\={u}}$tras(rope's rules), a collection of Hindu religious documents, was written between Vedic period(BC 1500~600). The geometry of Sulbas${\={u}}$tras in ancient India was studied to construct or design for sacrificial rite and fire altars. The Sulbas${\={u}}$tras contains not only geometrical contents such as simple statement of plane figures, geometrical constructions for combination and transformation of areas, but also algebraic contents such as Pythagoras theorem and Pythagorean triples, irrational number, simultaneous indeterminate equation and so on. This paper examined the key features of the geometry of Sulbas${\={u}}$tras and the geometry of Sulbas${\={u}}$tras for the construction of the sacrificial rite and the fire altars. Also, in this study we compared geometry developments in ancient India with one of the other ancient civilizations.

The Rule of False Position is known as an arithmetical solution of algebraical equations. On the other hand, the Excess-Deficit Rule is an algorithm for calculating about excessive or deficient quantitative relations, which is found in the ancient eastern mathematical books, including the nine chapters on the mathematical arts. It is usually said that the origin of the Rule of False Position is the Excess-Deficit Rule in ancient Chinese mathematics. In relation to these facts, we pose two questions: - As many authors explain, the excess-deficit rule is a solution of simultaneous linear equations？ - Which relation is there between the two rules explicitly？ To answer these Questions, we consider the Rule of Single/Double False Position and research the Excess-Deficit Rule in some ancient mathematical books of Chosun Dynasty that was heavily affected by Chinese mathematics. And we pursue their historical traces in Egypt, Arab and Europe. As a result, we can make sure of the status of the Excess-Deficit Rule differing from the Rectangular Arrays(the solution of simultaneous linear equations) and identify the relation of the two rules: the application of the Excess-Deficit Rule including supposition in ancient Chinese mathematics corresponds to the Rule of Double False Position in western mathematics. In addition, we try to appreciate didactical value of the Rule of False Position which is apt to be considered as a historical by-product.

"The Golden Mirror of Medicine(醫宗金鑑)" was compiled by the medical officers of the Qing government, headed by Wu-Qian(吳謙)."The Elimination &Supplement about the Famous Prescription Comments(刪補名醫方論)", a collection of notes written by famous scholars, is one part of "The Golden Mirror of Medicine(醫宗金鑑)" . Through the translation and comparative study of invigorative prescription(補氣方劑) in "The Elimination & Supplement about the Famous Prescription Comments(刪補名醫方論)" of "The Golden Mirror of Medicine(醫宗金鑑)" with "The Famous Prescription Comments on Ancient and Modem Times(古今名醫方論)" , we confirmed that many sentences of "The Famous Prescription Comments on Ancient and Modern Times(古今名醫方論)" were quoted, but that most of the text was not quoted as the same: it was revised and supplemented. In organization, invigoration prescriptions are placed at the head of the chapter, indicating their importance. In classification, prescriptions for reinforcing middle-jiao(中焦) and replenishing qi(補中益氣湯類 方劑) were usually included in the invigoration prescriptions(補氣方劑), which is explained in chapter II, thereby clearly distinguishing between treatments of deficiency of qi(氣虛) and combining it with the sinking of qi of middle-jiao(中氣下陷).
