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.

Seowon(書院) was an institute for education and sacrificial rite, established privately in rural villages throughout the middle period of the Chosun dynasty(1392-1910), where scholars researched classic studies, cultivated personal characters in accordance with the Neo-Confucianism, nurtured young disciples, and performed rites at a secluded shrine where spiritual tablets of honorees were housed. This study examines the architectural characteristics of Pilamseowon(筆巖書院) in Chans'seong, Chollanamdo Province, Korea. Through the study, the architectural characteristics of Pilamseowon were found as follows: First, Pilamseowon moved twice since it had been established. Second, through the moving, the area of Pilamseowon was expanded and buildings were added. Third, some buildings of Pilamseowon reflect the previous condition of the seowon site. Take Hwakyeonroo(廓然樓) as an example, which is the main entrance pavilion of Pilamseowon. Pavilion is an appropriate type of building in sloped site. Before Hwakyeonroo was moved to the present site, it was located on sloped site, where Hwakyeonroo accordingly took the pavilion type of building. Present site condition of Pilamseowon is plane, nonetheless, Hwakyeonroo has the pavilion type of building, which reflects the previous condition of the building site. Forth, Pilamseowon consists of six spatial domains and each domain has its own entrance gate to outer area.

High-rise apartments have a problem using natural ventilation because of the strong outdoor wind velocity. Conventional high-rise apartments have adopted mechanical ventilation systems to maintain the indoor air quality. However, it leads to the overuse of electricity and the sick house syndrome. Double-skin facade is the alternative for the high-rise building to use natural ventilation and this study is focused on the performance of the box-window, which is a kind of double-skin facades. Indoor wind velocity and HCHO concentrations are analyzed with three types of box-windows: the diagonal type, parallel type and perpendicular type. The airflow is simulated by computational fluid dynamics program. Box-windows reduce the maximum value of indoor wind velocity about 50% compared with the single window and the HCHO concentrations do not have the big difference. Box-windows could be the alternative to enhance the use of the natural ventilation and indoor air quality of the high-rise apartment.

Performing a series of in-situ thermal response tests, the effective thermal conductivity of six vertical closed-loop ground heat exchangers was experimentally evaluated and compared each other, which were constructed in a test bed in Wonju. To compare thermal efficiency of the ground heat exchangers in field, the six boreholes were constructed with different construction conditions: grouting materials (cement vs. bentonite), different additives (silica sand vs. graphite) and the shape of pipe-sections (general U-loop type vs. 3 pipe-type). From the test results, it can be concluded that cement grouting has a higher effective thermal conductivity than that of bentonite grouting, and the efficiency of graphite better performs over silica sand as a thermally-enhancing addictive. In addition, a new 3 pipe-type heat exchanger provides less thermal interference between the inlet and outlet pipe than the conventional U-loop type heat exchanger, which results in superior thermal performance.

The ground source heat pump system is increasingly being considered as an alternative to traditional heating and cooling systems to reduce the emission of ground house gases. In this paper, A series of numerical analysis for energy piles has been performed focusing on heat transfer efficiency, performance and thermal stress. Results of numerical analyses for the W-shape type shows more efficient heat exchange transfer than the coil type. From results of the thermo-mechanical analysis, it is shown that the concentration of thermal stress occurs around the circulating pipe and the interfaces between different materials. The largest deformation caused by thermal stress is observed in the energy pile.

'Lu' is one of the Korean traditional building structure. The architectural characteristics of the 'Lu' can be classified two types with its use. One is single building type and the other is a part of building type within building complex. This study is about the two-storied 'Lu' that was built on part of building complex. 'Lu' built in building complex such like Sa-chal, Hyang-gyo, Seo-won, Jae-sil, has the similar characters. 1. It is built by taking slope site. 2. Ii is one of four buildings that forms court yard. 3. It uses simple building structure on the purpose of openness 4. It can control view with using window. The column type of 'Lu' can be classified with 3 style. These are $5{\times}2$ Kan style, $3{\times}2$ Kan style and $5{\times}3$ Kan style. It would be assumed with the result of study that $5{\times}2$ Kan style has its origin in Hoe-Rang structure, $3{\times}2$ Kan style is originated from Joong-Moon(middle gate) structure, and $5{\times}3$ Kan is originated from Kang-Dang structure.

The push-out tests have been conducted on the specimens which consist of the steel beam with U-shape section and the cap-type shear connectors with constant intervals. Existing equations for the evaluation of shear connector strength have been investigated on the basis of test results. The reinforcing bars for longitudinal reinforcement and the penetrative bars for transverse reinforcement didn't have much effect on the shear capacity of the cap-type shear connector. The larger the width of cap-type shear connector was profiled, the greater the shear strength turned. The shear capacities of cap-type shear connectors with constant intervals were evaluated on the basis of push-out test results, and those were possible to be determined with proper safety margin using the Eurocode 4. The slip capacity of cap-type shear connector was shown to exceed the limit value of 6mm for sufficiently ductile behavior.

The percentage of apartment houses in residential buildings has increased every year, and it result in higher energy consumption of residential buildings. After the house law could be amended to legalize the remodeling of the balcony, buyers and contractors prefer to choose the balcony remodeling type when they choose a house for installment sale. Many construction companies design an apartment house considering balcony remodeling. So, this paper compares the balcony remodeling type with the basic type(prior to remodeling balcony) by using the building energy rating system tool. The balcony remodeling type consumes heating energies more than the basic type, and is unable to receive high rating. If the balcony is remodeled, it is required to improve the performance of wall and window and reduce the area of remodeling balcony.

The remaining Joongjaesil(中齋室)-type pavilions in the eastern part of the Jirisan Mountain area showed more complex characteristics than those in the western part. The front number of kan(間) had two, three, and four kan (間) types, but the number of kan on the side was consistent with two regardless of the number of kan on the front. The pavillion is classified into 'central type', 'towards the backward type', and 'expanded by backwards type' according to the location of Joongjaesil. Joongjaesil's size, which characterizes the characteristics of Joongjaesil-type Pavilion, is related to the building's front number of kan. Front number of kan. When this space was increased by one space to four spaces, Joongjaesil must have two spaces. The pavilion with four bays in front showed the characteristics of being concentrated in Sancheong and Jinju, the eastern part of the Jirisan Mountain area. In the eastern region, many high pavilions remain, and the upper structure of the pavilion was insignificant, but the flat shape and public construction showed strong locality.
