This study examined public building remodeling projects in France. Through investigating cases of ancient buildings remodeled in France, the study aimed to provide fundamental data and analysis for remodeling public buildings. Accordingly, seven cases were analyzed in terms of remodeling methods, architectural characteristics, methods of conservation, and restoration of ancient historical buildings, as well as a change of usage of an existing building. As a result, this study found the criteria of French ancient building remodeling. The remodeling methods of an existing building vary in their goals and strategies depending on how the old architectural elements are persevered, as well as how new elements are added to form their unique characteristics. Thus, the remodeling methods are classified into four types based on causes: restoration, extension, renovation and rebuilding. Such methods are used jointly rather than individually. The ancient building remodeling is the process of recreating new functions and new artistic values to preserve the cultural and artistic values of existing historic buildings.

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.

The purpose of this study is to reveal the wood joinery technique in the ancient era. Joinery is one of the core techniques in constructing timber frame architecture in the Korean peninsula. These techniques can be revealed by examining wooden members of ancient buildings. The members were excavated at the Donggung Palace and Wolji Pond, the historic site in Gyeongju. This study collects the data of 284 members excavated at the Donggung Palace and Wolji Pond and analyzes the details such as length, thickness, width, joint types, joint shapes. With the result of the analysis, this study tries to indicate the level of wood joinery techniques in ancient buildings.

The basestone is a kind of foundation part of the building and can be said to deliver the loads from the upper part to ground. It is the explanation of structural role for the basestone. But the basestone has been used as the decorative element in a building. So this study is on design of the basestone. First the type division can be studied as form of the basestones. Also the investigation of development aspect of them needs to as times and the spatial characteristics. Another goal of this study is on the design characteristics of the basestone from the comparison to the basestone in ancient Japan was initiated in the architectural technology from Korea. The results are as follows. In Baekje rectangular basestones were used in static space for ceremony and circular ones were used in dynamic space for life. Also the basestones with joojwa(smoothing surface for sitting on column) were used for accessory buildings rather than main. In Silla the same type of basestone was made in a temple but according to hierarchy of buildings the sizes of them seem to have been different. The other side in Japan carved basestones were for the main buildings and for the accessory natural stones were used to. According to the hierarchy of the buildings the kinds of stones were different.

For cities with ancient buildings at core areas, night lighting is an effective means to demonstrate their history and culture. In this regard, night scenes of these ancient buildings are evaluated from multiple aspects, such as color rendition, brightness ratio affected by ambient light and technological realization of lighting facilities. This study builds a visual evaluation system for night scenes of ancient buildings based on three dimensions, namely ancient architecture carrier performance, visual perception and technological realization, and explains specific evaluation sub-criteria one by one. In addition, this study adopts Analytic Hierarchy Process (AHP) to analyze the impact of each sub-criteria item on the weight of the whole evaluation system, and conducts a consistency test to show that the evaluation system meets the reasonable requirements of hierarchy setting. Moreover, relative importance of each sub-criteria item may be determined based on their corresponding weights.

We investigated the changes in the species of the woods used for Korean ancient and historic architectures, which include prehistoric excavated relics and existing wooden buildings in South Korea. The species data were collected from various sources such as excavation and repair reports, journal papers, and a few unpublished documents. We divided the building Periods as Paleolithic, Neolitic, Bronze Ages, Iron Age/Three Kingdoms, Koryo, Joseon (early, middle, late) and modem periods. In prehistoric periods, hardwoods were major species. Oak (Quercus spp.) woods dominated (94 percent in average); the others (5%) were Juglans mandshurica, Platycarya strobilacea, Castanea crenata, and few softwoods(1%). During Iron Age and Three Kingdom periods, oaks remained as a major species (57%) and others Platycarya strobilacea(21%), Castanea crenata(13%), and Pinus spp. (6%). The oak woods decreased in Koryo period and they occupied only 1.1%. Instead of oaks, pine (Pinus spp., 71%) and Zelkova serrata (22%) dominated in Koryo. In early and middle Joseon periods, pine woods (73%) remain as a major species and the others were oaks (14%) and Zelkova serrata (9%). As late Joseon came, the pine woods occupied more than 88%. In the late 19th and early 20th centuries, a few boreal species such as larch (Larix spp.) and spruce (Picea spp.), which grow in cold area, were found. We believe they were transported from northern Korea. The existing buildings in Korea are mainly from Joseon period and a few from late Koryo periods. During these periods, pine woods were used for most buildings. For such reason, pine woods were known as 'representative materials for historic buildings'. but earlier times, broad-leaved trees, i.e., oak and Zelkova woods were major materials. The changes in building materials resulted from both climate and human impacts. The dry climate and disturbed forests induce more pines in the mountains. We also compared the wood qualities of the species and found that Zelkova woods were superior ones and deserved more planting for future demands in the repair for historic buildings.

To study the mechanical properties of joints in ancient timber buildings in depth, the force mechanism of the through-tenon joints was analyzed, also the theoretical formulas of the moment-rotation angles of the joints with different loosening degrees were deduced. To validate the rationality of the theoretical calculation formulas, six joint models with 1/3.2 scale ratio, including one intact joint and five loosening joints, were fabricated and tested under cyclic loading. The specimens underwent the elastic stage, the plastic stage and the destructive stage, respectively. At the same time, the moment-rotation backbone curves of the tenon joints with different looseness were obtained, and the theoretical calculation results were validated when compared with the experimental results. The results show that the rotational moment and the initial rotational stiffness of the tenon joints increase gradually with the increase of the friction coefficient. The increase of the tenon section height can effectively improve the bearing capacity of the through-tenon joints. As the friction coefficient of the wood and the insertion length of the tension increase, the embedment length goes up, whereas it decreases with the increase of section height. With the increase of the looseness, the bearing capacity of the joint is reduced gradually.

In this study the foundation methods which our ancestors, through a historical age as early as three kingdom's period, adopted for their civil structures and buildings have been reviewed by investigating the discovered relics. It is shown that they already, from about 2000 years ago, had applied various foundation techniques considering the structure types and the foundation soil conditions. The ancient foundation methods are categorized as artificially laid alternating soil and boulder layers under heavy structures, compacted soil base under wide loaded area, stone column under pillars of buildings, stacked long stone footing for special buildings such as palace buildings, and piling for bridges, They are analyzed with respect to current foundation techniques.

After 1840 the first opium war, that changed the social nature and living habitats in China. The purpose of this study is to observe the influence of the war on the plan layout of traditional Chinese residential houses in Beijing Siheyuan. To find out the changes that were made after 1840, and reservation of the past, the space syntax model is used to analyze different social contexts and also compare the ancient and modern residential buildings. The result of the study indicate the following: Before the war, the ancient Siheyuan people's way of life strictly abide by the hierarchy system; External emphasis shows the host's status. However, in modern times, the social status became equal, efficient and harmonious relationship internally, while externally, it arranged the orientation and position of buildings to adapt to the natural environment. However, the boundaries between family members and visitors the emphasis on the courtyard and respect for private life remain unchanged.

This paper analysed the architectural images on Pleasant Gathering of Leeum, Samsung museum of art, which has been assumed as a work of the Koryo dynasty. Through the comparison between the unique wooden structure at roof edge on the building images and real architectures, it found the buildings on the painting were from China Fujian(福建), not from Korea. It also analysed the color painting on buildings, trees, themes from previous famous paintings and dresses to confirm these images were came from the early period of the Ming dynasty. It is a very unique painting containing various information on the Fujian ancient architecture, but its architecture drawing is not as skillful as typical ancient Chinese paintings.
