This research considers the characteristics of the plan of the vernacular form of dwelling in KoCheon-Ri village, situated in the Yong-Dong mountain region. As part of this study, an analysis of local diversity is carried out. The current existing village houses in Kocheon-Ri can be categorized according to their floor structure, either as a wooden-floored or an Ondol-floored Kyup-jip(a double row house type). It was found that the wooden-flooded Kyup-jip house has been transformed into Ondol-floorded Kyup-jip due to a range of various factors. In order to clarify the characteristics of the vernacular dwelling type occurring in a particular area, it is important to determine the typical form that appears within the broader area. However, differences is also essential.

The purpose of this study is to investigate the present status of dwelling spaces and deduct sustainable elements in transformation of them by comparing the restored drawings with the surveyed drawings focused on traditional houses that exist in the urban area of cheongju city in Korea. In alteration and extension of these traditional houses, scale of a private room became larger as it has been connected and expanded, the exterior main hall (Daecheong) became the interior living room, and the conventional kitchen was westernized and changed from K type to DK or LDK type. The toilet located at outside was installed by the attached aisle (Toetgan) inside and the existing room. The extension was completed with equipments, storage space, and rental accommodation. The conservative and sustainable elements in the various transformation of them are as follows. Firstly, it was to maintain 3 rooms such as main room (anbang)-main hall (daecheong)-detached room (gunnunbang). Secondly, it was to sustain the circulation of kitchen and arrangement of the - type worktable even though it was westernized. Thirdly, extension of storage space was completed less than 600 mm within the eaves. Although there were functionally and structurally many changes in 18 houses, 4 houses had maintained wooden floor of main hall, 5 houses long planked wooden floor of the attached aisle, and 12 houses rafter ceiling of the main hall and the attached aisle.

This research work is to analyze architectural characteristics of Sungnyemun especially in King Yeongjo's reign in Joseon dynasty. The result of this research is summarized as following: 1. The architectural characteristics of Sungnyemun in King Yeongjo's reign are closely related with Confucian ceremonies such as Jeon-jwa and Heon-goek-rye. To perform these ceremonies, some lower walls of Sungnyemun's wooden pavilion were removed and used as ceremonial space. And after ceremony it was restored. 2. The floor type of center bay of the 1st story of wooden pavilion should have a type of floor using long and narrow fine tree plate, which is same type before the repair work of 1960's dismantlement. 3. The width of east stairway which is reached to east small gate, was changed just before Japanese's rule(1910~1945), should be broaden than present width, which is proven through the recent excavation. 4. The reason of asymmetric characteristic of locations of both east and west narrow-gate, and widths of east and west stairway, are related with order of King's ceremony. * Jeonjwa : a ceremony to see national affairs or receive royalty from officials in main hall or main gate of palace in Joseon dynasty (some times open to public) * Heon-goek-rye : a ceremony after win a war and offering to king enemy's ear or head in Joseon dynasty.

In order to secure the variability of long-life housing, dry walls are used. The composite gypsum board panel is the most frequently used infill system for the wall, and it is an excellent construction method in terms of constructability and economic feasibility. However, there are also problems such as the destruction of Ondol pipes at the bottom floor and being unable to fix the light weight steel frame (M-bar) when a variable composite gypsum board panel is used. To solve such problems, a wall with a method of fixing only the top part without fixing the bottom floor is developed, but it is difficult to identify the durability of ceiling frame according to the tensile force of stud and the safety according to the Stiffness and impact resistance (soft body) of ceiling frame. Therefore, this study verified the effectiveness of infill system for the wall by conducting experiment on the stiffness and impact resistance of composite gypsum board panel according to the reinforcement of ceiling frame (wooden frame, double saw-toothed bracket, Cross M-bar). As a result, it was possible to secure the safety of wooden frame while the impact resistance and the Stiffness of double saw-toothed bracket and cross M-bar were not secured.

The plan of Korean traditional houses are devided by the span-units which is the automatic result of the timber construction. This study aims to analyze the ways plan type change when the number of span changes. One village named Bangchon in Honan Province was selected where we investigated more than 30 houses ranging from 3 span to 6 span. It is identified that there were certain rules which govern the plan change when number of span change. When one span is added onto 3 span houses, wooden floor of one span is added in between the two ondol-rooms. When one span is added onto 4 span houses, kitchen is enlarged. When one span is added onto 5 span houses, wooden floor is enlarged into 2 span, Also the plan of Man's quarter(Sarang-chae) was investigated and compared to Lady's quarter. The research proves that such rules of plan change need to be considered as a basic standard of analysis when traditional houses are to be studied.

This study aims to classify and find the characteristics of the housing floor plan by their spatial organization, the condition of use, the process of changes in Jeonju Hanok Village. To carry out this study, first the 534 in 779 housings in this village are investigated, and finally 55 of them are investigated and analyzed. They are surveyed and investigated from November in 2008 to January in 2010. The followings are as conclusions; The prototype of housing floor plan in this village is consisted of the main room in the middle part with the toimaru (wooden veranda), kitchen and meoribang (the room that is located back or the side of the main room) and kennen-bang (the room that is located the side of main room) in it's house. They are generated and changed on the basis of this type. The floor plans of the housings in Jeonju Hanok Villages are classified and characterized as the type of original floor plan house (original type), that of semi foreign house with the Korean style by the Japanese style or modern style, that of the house for rent a room or two rooms or one family, that of the house which mixed with commercial function and that of etc. They are generated by the social and economic condition of that period. And they will be studied with the life style of residents.

Historical study of Korean traditional houses have been carried, mainly, based on the geographical region of Korean peninsula. However, the case of primitive houses can not be researched according to the geographical and racial concept of modern nations. This study aims to examine the primitive houses of ethnic minorities of northeastern China, where the cultural and racial background have been deeply rooted in the history of Korea as well as Korean traditional houses. Through the field research and literary materials, the basic types of primitive houses of the five ethnic minorities could be identified. Among these types, those that have possible relationship with Korean houses, are cone shaped house, underground house, and elevated wooden house. Archeological evidences of underground houses were amply found in Korea already, but above ground evidences could not be found. However, It seems quite certain that the cone shaped houses and elevated wooden houses, too, existed in Korea as one of the earliest housing types, as can be examined in remaining examples in Korean peninsula. With no doubt, the primitive houses of Korea have strong connection with that of the ethnic minorities of northeastern China. This can be verified through the facts that the evidences of cone shaped houses, the similarities of the use of Inner space, the evidences of elevated wooden houses. Also, the combination of wooden floor and ondol, which is known to be one of the strongest characteristic of Korean traditional houses, could be originated from the combination of primitive summer house, the elevated wooden house, and the winter house, the underground house with ondol.

The aim of this study is to identify the floor plan types of folk houses or traditional vernacular dwellings found in Nagan Folk Village located in Joellanamdo province. Examining the floor plans appeared among 36 vernacular folk houses presumably built in the 19th century in the village by means of the changes in the number of bays of Anche, the mail block of the house, the study was also able to construct a spatial compositional process of floor plan development. The floor plan examination revealed that the basic floor plan type in Nagan folk housing was '一' shape, a typical southern dwelling based on the existing classification. This basic type is consisted of three bays or rooms: Jeongji (kitchen), Anbang (large room), and Jageunbang (small room). New spaces or rooms are added to this three room house to expand the house as the residential functions become more complex, such as more living and storage spaces. The expansion appears to have two direction. On the one hand, it has been taken place by inserting Marea, an open wooden floor living space between Anbang and Jageunbang to meet the extended living demand. On the other, Jeongjibang, a second kitchen/storage has been attached to Jeongji outward for extra cooking and storage. This two-way expansion shows the trend of symmetric expansion between cooking, storing space and dwelling space. It can be implied that the arrangement of house rooms has been structurally formulated and shared by the farmer-builders in the 19th century in Nagan village who appeared to be influenced by fixed images for housing.

Building energy simulations which are mainly used in Korea have evaluated the building energy performance with the different thermal conductivity of construction materials. In order to evaluate the energy consumption accurately, the difference in thermal conductivity of the wood used in stud for wooden structure was confirmed from the each simulation. In addition, the thermal transmission of building members and the thermal bridge at the conjunction of building members according to thermal conductivity from each simulation programs were researched. The thermal conductivity of pine that has the largest variation among the energy simulations was applied to the thermal properties of studs in wooden structure. The maximum error between the maximum and minimum thermal transmission of roof, wall, and floor slab was $0.023W/m^2{\cdot}K$. Plus, that thermal bridge at Rafter junction on the roof, roof-wall joint, and floor slab-wall joint was $0.025W/m{\cdot}K$. The heat transfer image for changes in temperature and the heat exchange were analyzed by HEAT2 program. The distorted temperature lines were found around the insufficient insulated connection parts. It was predicted that the temperature at the distorted parts in the analyzed image was lower than that of the other portion of the other structures.

The Main Hall of the Fengguo monastery in Yixian county, Liaoning province, China, is the best preserved and largest wooden Buddhist structure, typical of the Liao dynasty style, in China. However, some degradation to the timber frame of the Main Hall has been noted, and this is causing concern in terms of the long-term preservation of the structure. In this study, wooden pillars showing the degradation phenomena of whitening, for areas in contact with the stone floor, and extensive surface damage at higher locations(mostly above 1 m) have been examined. Samples taken from wooden pillar surfaces were analyzed using X-ray powder diffraction, Fourier-transform infrared spectroscopy(FTIR), ion chromatography, and pH measurements. With respect to the whitening phenomenon, we found inorganic calcium precipitates and oxalate ions, along with higher pH values. These symptoms indicated that chemical changes were taking place in response to alkaline conditions, suggesting that alkaline mixtures with calcium content in the foundations may be responsible. Regarding the upper surface-damaged areas, no valid evidence for chemical degradation was found using FTIR analysis, while damaged areas exhibited the presence of more bat guano-related materials than which were apparent in undamaged areas. The occurrence of this surface-damaged phenomenon has therefore been attributed to physical damage caused by bat activity over long periods of time.
