The history to have used lime in building construction was much long without distinction of the East or the West. The ancient nations of korean peninsula had used lime as construction material. The witness was discovered in the kings' tombs of fifth century. In the Joseon dynasty(15~19c), what applied several developed lime compounds to the kings' tombs have been recorded in 'Sanleong-Uigwe(山陵儀軌)' & 'Yeonggeon-Uigwe(營建儀軌)' of those days documents. Therefore, this paper is to examine the whole procedures from the product and provision of lime to its application through those days documents. Following conclusions have been reached through the study. Three lime compounds to be developed for the kings' tombs was extendedly applied to residential government buildings step by step within the current of time. These compounds to be used in the kings' tombs of the Joseon dynasty had been correlated to those of the ancient nations, which were nations of korean peninsula in narrow range, chinese and orient nations in broad range. These compounds have possibilities of development as the environmental-friendly building material. And these compounds should provide a standard specification for conservation & restoration of the traditional and cultural properties. I could confirm that the whole procedures had not been developed within limited space-time of the specified nation & period, but within interactions of the nations & periods. In the periods which disturb its interaction, the expansion of productivity in building construction was interfered.

This paper deals with the restoration of ancient wooden bridge foundation which excavated in Seta river Shiga Prefecture, Japan. Shiga Archeological Research started a marine archeological investigation of the bridge foundation in 1987. The bridge foundation stricture excavated and have since then recovered about a lots of woods and another materials. The bridge foundation structure constructed log, timbers and stones. The species of those waterlogged wood were identified as two types, hardwood and softwood. Hardwood(log : Cyclobalanopsis) was used for below foundation and softwood (timber' Chamaecyparis obtusa Endl. Cupreessaceae) was used for base structure. One of those timber sample dated by dendrochronology, we asked Dr. Misutani*. The softwood gave a felling date of 567 A.D. In result, the ancient Seta bridge foundation structure had constructed between Asuka and Nara period. We healed the news that ancient bridge foundation excavated at Woljyongyo site in Kyongju, Korea 1987. The bridge foundation Setakarahashi is similar in plane and structure to Woljyongyo structures. The Woljyongyo site report had be of value for reference. We had planning to restore those woods. Hardwood log was got serious damage. The water content varies from 400 to $600\%$. The other timbers water content varies about $200\%$. In the Shiga Center for Archaeological Operations and the Azuchi Castle Archaeological Museum, we set up the PEG impregnation tank. Those wooden objects treated by PEG method. PEG with a molecular weight of 4000. The treatment results may be considered satisfactory. The ancient wooden Seta bridge was reconstructed in Biwako Museum which established in Oct. 1996. We must take care of indoor exhibition environments.

This study focuses on the regional characteristics observed in the composition and floor plan of folk houses in the Young-cheon region situated in the Southern East inland of Gyungsangbukdo. According to the typical characteristics of the Korean folk house, Young-cheon region is supposed to be classified as the Young-Nam region. Our study shows that the open inverse 'ㄱ' type composition is the most common among others, which consists the living room, UtChae and one BoosokChae that serves as a living room and a farm shop. The typical floor plan is called 'Young Nam type' 'H$\hat{o}$tjib' composed of four rooms. Young Nam type of house has a wall in front of the room floor with a door to make the space with the room floor as the internal space. This can be explained by the climatic conditions in the Southern region of Gyungsangbukdo, which has a very cold winter and has a harsh spring wind in Young-cheon. The structural feature to which we should pay attention is the Young Nam type house has a gambrel roof. The evolutions of the house in the 70s are observed in the roof during the Saemaeul Movement from a hut to a modernized roof. In the 80s, the replacement of the heating system, expansion of rooms, modernization of kitchen, replacement of paper windows, modernization of roof, and construction of amenities had taken place to change the space, construction and structure following the modern house features.

본 연구는 라틴아메리카의 일부 지역인 안데스와 리버플레이트 지역에서 양보접속사구로 기능하는 [todavía que]에 대한 형태-통사적 그리고 의미적 특성을 연구하고자 한다. Real Academia $Espa{\tilde{n}}ola$(2009)에 따르면 부사 todavía는 초점과 관련된 다양한 맥락에서 사용되며 특히 안데스와 리버플레이트 지역에서는 [todavía que]가 양보구문을 형성하며 첨가적 해석을 갖는다고 한다. 케추아어의 접미사 '-raq'과 아이마라어의 접미사 '-raki '는 스페인어의 부사 todavía와 동일한 의미를 갖는다. 그러나 이 두 원주민 언어에서는 상기의 접미사가 첨가 초점사의 기능을 수행하지만 스페인어에서는 첨가 초점사로 쓰이는 접미사는 없으므로 이러한 범주적 불일치로 인해 [todavía que]구조에서는 todavía가 부사의 형태로 접속사 que와 함께 첨가 초점사로 사용된다. 본 연구는 이러한 형태-통사적 그리고 의미적 특성은 두 원주민어들과 스페인어의 언어접촉 현상에서 비롯된 것으로 주장한다. 또한 이러한 주장에 기초하여 스페인어의 부사 todavía가 어원적으로 전칭양화사와 관련되는 사실과 척도와 관련된 자질을 내포하는 특성에 기인하여 [todavía que]는 척도 첨가의 의미를 갖는 양보의 접속사로 기능한다고 주장하고자 한다.

'In-Jon(人尊)' is one of a concept which constitute the mainstay of Daesoon thought. To be superficial, the concept is appeared to be limited at a area of anthropology, but In-Jon is a large concept which includes ontology and epistemology. Because the essence of human being is connected with God and the such possibility is related to the mission of human being's subject who exists in world. Advanced researches to analysis of in-jon tend to focus on rise of human status but this study do on universal subject not particular subject. This is to elaborate the point of issue. The point of view as rise of human status overlooks problem of relationship between human entities. who ingenerate hierarchy. In-jon is the universal subject of philosophical subject concepts which western philosophy have taken as main problem since Descartes. So we have to consider In-jon to be conceptual continuity concerning stream of history of ideas and communicate with ideas. A precedent study on 'injon' concept has weak conceptual analysis, which only emphasizes the greatness of mankind as compared with others. But that can't reveal In-jon based on the Daesoon thought. So I try to engraft the concept on development of subject ideas to get academic objectivity. In-jon is great in having universal subject to expand the authority of God to all creation. That is the last goal which subject can reaches through the development. Considering this regard the research direction of this study is very encouraging and significant. Western philosophy has important philosopher of the three, Descartes, Kant, Hegel. Those are a spectrum who show an aspect of subject ideas. The subject idea has become the middle of philosophical system since Descartes in modern. It is the right and necessary process to philosophy because human being has spirit or reason connected with God. So In-jon in Daesoon thought is academic concept comprising ontological and epistemological properties. So I try to analyse In-jon through that and have In-jon join the ranks of mainstream academics in this paper

This paper developed and examined a novel passive vibration isolator (i.e., "X-inerter") motivated by combining a bio-inspired structure and a rack-pinion inerter. The bio-inspired structure provided nonlinear stiffness and damping owing to its geometric nonlinearity. In addition, the behavior was further enhanced by a gear inerter that produced a special nonlinear inertia effect; thus, an X-inerter was developed. As a result, the X-inerter can achieve both high-static-low-dynamic stiffness (HSLDS) and quasi-zero stiffness (QZS), obtaining ultra-low frequency isolation. Furthermore, the installed inerter can produce a coupled nonlinear inertia and damping effect, leading to an anti-resonance frequency near the resonance, wide isolation region, and low resonance peak. Both static and dynamic analyses of the proposed isolator were conducted and the structural parameters' influence was comprehensively investigated. The X-inerter was proven to be comparatively more stable in the ultra-low frequency than the benchmarking QZS isolator due to the nonlinear damping and inertia properties. Moreover, the inertia effect could suppress the bio-inspired structure's super- and sub-harmonic resonance. Therefore, the X-inerter isolator generally possesses desirable nonlinear stiffness, nonlinear damping, and unique nonlinear inertia, designed to achieve the ultra-low natural frequency, the anti-resonance property, and a wide isolation region with a low resonance peak.
