The term '健康(heathy condition)' does not appear in East Asian medical classics. Its root comes from the ancient word 'hal' which can be translated as 'hale', 'whole', 'sound in wind and limb', and it means 'the physical state is flawless, whole, satisfactory, and strong'. The Japanese translated it into the Chinese letters 건강 in the 19th century and this was spread during the Japanese occupation era. This study is an attempt to explore what "huangdineijing" (the most representative medical documents of East Asian medicine) mentions about healthy condition, which is as a term to express the body's ideal state and what other concepts exist that correspond to 健康.

Obviously the speed of dissemination of new, modern ideas in Jiangnan was closely related to the development of transportation. Looking back at the history, the backwardness of transportation in the early modern Jiangnan restrict the dissemination of new ideas in this region and then the situation changed a lot since the 1890s, when the spatial distance between Shanghai and Jiangnan was remarkably shortened, the dissemination of new ideas was accelerated, and the new ideas in return significantly influenced the Jiangnan society. It was the constantly improved transportation that facilitated the diversification of channels disseminating information and made the dissemination itself faster. As a consequence, the new ideas, knowledge, and things were rapidly disseminated and popularized in Jiangnan, thereby giving impetus to the social changes in this region.

It has been argued that as for the origin of the Pythagorean theorem, the theorem had already been discovered and proved before Pythagoras, and the historical records of ancient mathematics have confirmed various uses of this theorem. The purpose of this study is to examine the relevance of its name caused by Eurocentrism and the weakness of its use in Korean school mathematics and to seek improvements from a critical point of view. To this end, the Pythagorean theorem was reviewed from the perspectives of the history of mathematics and mathematics education. In addition, its name in relation to objective mathematical contents regardless of any specific civilization and its use as a starting point for teaching the theorem in school mathematics were suggested.

Ancient masonry towers are regarded as among the most important historical heritage structures of the world. These slender structures typically have orthogonal and circular geometry in plane. These structural forms are commonly installed with adjacent structures. Because of their geometrical shapes and structural constraints, ancient masonry towers are more vulnerable to earthquake damage. The main goal of the paper is to investigate the seismic behavior of Erzurum Clock Tower under earthquake loading and to determine the contribution of the castle walls to the seismic performance of the tower. In this study, four three-dimensional finite element models of the Erzurum Clock Tower were developed and the seismic responses of the models were investigated. Time history analyses were performed using the earthquakes that took place in Turkey in 1983 near Erzurum and in 1992 near Erzincan. In the first model, the clock tower was modeled without the adjacent walls; in the second model, the clock tower was modeled with a castle wall on the south side; in the third model, the clock tower was modeled with a castle wall on the north side; and in the last model, the clock tower was modeled with two castle walls on both the north and south sides. Results of the analyses show that the adjacent walls do not allow lateral movements and the horizontal displacements decreases. It is concluded that the adjacent structures should be taken into consideration when modeling seismic performance in order to get accurate and realistic results.

This paper aimed to identify the architectural characteristics of the chimi excavated from ancient ruins, especially middle gate remains of Bunhwangsa Temple in the Unified Silla period. Middle gate had planned $3{\times}2$ with 295mm measuring unit and gabled building. Detailed study of the shape of chimi of the middle gate restored by related field experts reveals as follows. 1) Height of chimi is 4.5(130.6cm) of Tang's system of measurement classified as large one. 2) The front and back side square hole is made for transverse timber placement. 3) Position of chimi is not the end of the ridge of roof, it moved toward the center. 4) Construction method of chimi is structured with smaller beam and center column. 5) Width and height of the ridge is less than 38cm and 54cm to be approximately, Width and height of the gabled ridge is less than 38cm and 50cm. 6) This chimi is considered to be very unique when compared to existing ancient restored chimis, it is designed to be advantageous to the chimi construction.

In this paper we have inferred the influence of Zeno on the construction of the potential infinite of Aristotle based on arguments of Zeno's paradoxes. When we examine the potential infinite of Aristotle as the basis of the ancient Greek mathematics, we can see that they did not permit the concept of the actual infinite necessary for calculus. The reason Why they recognized the potential infinite, denying the actual infinite as seen in Aristotle's physics could be found in their attempt to escape the illogicality shown in Zeno's arguments. Accordingly, this paper could provided one of reasons why the ancient Greeks had used uneasy exhaustion's method instead of developing the quadrature involving the limit concept.

Throughout the history, the people of Iran have battled the dryness by innovations to preserve every drop of water that lands from the rare clouds, or from a stream flowing out of distant springs. Water is precious and held with highest respect, whether stored for drinking at an Ab-Anbar, or for washing and farming at the Houz in the middle of their oasis homes and orchards, or sourced at a Qanat spring or Jooy under ground. How it is that drinking water as cold as a mountain fall is found in desert of Iran? Ab-Anbar is an ancient means of water preservation and cooling through anunderground building structure. These underground structures have been present in Khorasan and other desert provinces of Iran as public or private water storage facilities, widely used before the installation of public plumbing systems in the late 1950s. Although many of these structures are still functional, most have been protected by government for restoration or viewing by the public as historical heritage. Khorasan natural dry climate and the massive surrounding deserts have been a breeding ground for many designs of Ab-Anbars. Today the existing number of such facilities stands in the province of Khorasan. Usually these structures were built in populated areas, also there are some forms of such structures on old trade routes and roadways leading to and from populated towns. This paper considers the history of Ab-Anbars in Khorasan as well as other relevant aspects such as types, components, construction methods and materials, filling and withdrawal systems.

A very unique case is found in the architectural remains related to the north and south square-platform at the lecture hall site of Hwangnyongsa, that of Anyangsa, and the estimated lecture hall site of Beopsusa as they are not observed in the other lecture halls. The platform has been discovered at only those three Buddhist temples from Goryeo, and its case has not been found in ancient Buddhist temples of China and Japan. This study thus set out to investigate the north and south square-platform at lecture hall sites by examining in details its architectural remains at the three Buddhist temples and reviewing the Buddhist literature about the lecture halls of ancient Buddhist temples. Based on the findings, it was estimated that the architectural remains of north and south square-platform at the lecture hall sites of Buddhist temples were those of platform for Buddhist sermons or those of high chair platform. While the north square-platform involved the remains of north high chair for the Lecturer that gave lectures on the Buddhist scriptures, the south one did those of south high chair for the Reader who recited the Buddhist scriptures.

"Ohju Yeonmun Jangjeon Sango" written by Lee, Gyu-gyeng is one of the most important encyclopedias in the period of Chosun-Dynasty. There are two chapters related to architecture in this book, one is "ancestral rite governance·human"chapter, and the other is "architecture·human" chapter. Both of them are hard to understand because they are written in ancient Chinese and consist of various quotations in ambiguous way. This paper as a partial study is deal with the former. It makes difference between writter's original texts and quotations through textual research, and translates to modern Korean, and analyze information about ancient architecture in texts. The texts can divide to three sections. The first introduces three Chinese architectural theory books as "Gogonggi(考工記)", "Yeongjo Beopsik(營造法式)" and "Mokgyeng(木經)", and mentions about the prototype of the royal ancestral ritual building in "Gogonggi Toju(考工記圖注)". The second quotes "Seoyeong(書影)" to introduce "Yeongjo Beopsik". The third quotes "PaePyeon(稗編)" to introduce "Yeongjo Beopsik" and "Mokgyeng", and mentions about the counting unit of columns of the royal ancestral ritual building. Although the purpose for these quotations is not directly mentioned, but we can find it is intended to explain the architectural prototype and lay-out of the royal ancestral ritual building.
