Winsborough Hall built by Martin L. Winehart who was the missionary of the Presbyterian Church of America in 1927 was built by Mrs. Winsborough's birthday contribution. Winsborough Hall was clearly divided into the original form built in 1927 and remodelled form by extension. Most of walls were constructed with several kinds of bricks for both sides and opening in the original form and remodelled form. Each room divided by inner wall was kept with original form because it is difficult to remodel it on the characteristics of building. But, it was confirmed through the related literatures that security of opening at some rooms and annexation of rooms through removal of the wall on the 2nd floor which was relatively easy to transform wall compared to the first floor were made. Variability of the wall affected the truss structure of roof and it created rare double truss structure. Architectural value of Winsborough Hall was in its first architectural trial using red brick in Gwangju region since 1920s. It suggested that it was differential architectural trial from Korean-Western mixed building constructed by the missionaries from 1940 to 1910 and buildings made of gray bricks prevailed from 1911 to 1920 and it showed the advancement in the architectural structure and materials.

The apartment will be much more convenient than the other one in the application of green technologies, providing the merits by mass production. For example, pre-manufactured building materials can be effectively adapted to the formation of buildings. Recently, the form of double-enveloped window system has been developed for the purposed of minimizing energy loss occurred around windows. On the other hand, the expansion of balcony area was legalized and thus, a visual buffer area does not exist any more. All-glass window wall on apartment houses without a balcony produces pretty harmful area with direct sunbeam. A various types of glass can be applied to the window system and it plays a critical role in the determination of inner visual environment. For the purpose of verifying the potential of its daylighting, a mock-up model has been constructed and tested. The refurbished version of conventional window shows its illuminated characteristics. Clear and Low-e glass have been adapted for window area and daylighting ratio has been compared in both test cells.

In this study, the plane type of main building relics of unified Silla period house site which excavated in Gyeongju city after 1990s was classified and the architectural characteristic of them was investigated. The chronology of building relics in Silla capital city site was mostly known as 8-9th century, and by standard of column arrangement, the plane types of them could be classified as grid type, front veranda-grid type, outer column type. The outstanding characteristic of plane is wide span and open front veranda. In most relics the span were over 4 meters, and inner foundations for small post and strip foundation were found between columns. The front veranda added type buildings were composited of enclosed main room and open front veranda, and column arrangement of them dose not fall into line in most case. Thus it thought that the structures of enclosed main room and open front veranda were independent. The interior space of enclosed main room were divided two rooms by partition wall in some case. In this case, one room is enclosed by wall, and the other room has open front side. This plane is considered for the pleasant life in cold winter and hot summer.

A collective theory is tried in analysis on the architectural history of Temple Gowoon in Gyongbook Province. For this purpose, firstly, the chronicle of construction was composed based on the critical study of the old documents. Secondly, the drawings of existing facilities were made after the field survey. And lastly, the collective theory was be able to extracted from the relation between chronicle and physical composion of the Temple Gowoon. The whole temple is composed of two territories, northern one and southern, which are divided by the central ravine. Northern territory was enlarged from Gukrakgeon's cluster through Myongboogeon's to Yeonsoogeon's. On the other hand, southern territory was reduced its position and its size from Daewoongeon's cluster, which was one of the main cluster, to Monigeon's, sub one. These processes were the results of the architectural adjustment, that is say, the dogmatic principles adapted in the topographical environments. The collective forms of clusters are different from each other. Gukrakgeon's cluster is composed of four buildings which enclose the empty inner court. Monigeon's is similar to the small temple type, Myongboogeon's selects the straggling form, and Yoensoogeon's has the type of Confucian shrine. The various types of clusters were the physical settings to symbolize the religious heirarchy of their buildigs. In the front of temple area, Gawoonloo, which located on the ravine and has a big volume, integrates straggling clusters.

The structure of the variable liquid column oscillator(VLCO) is analogous to that of the tuned liquid column damper used to suppress oscillatory motion in large structures like tall buildings and cargo ships. VLCO is using the technology which absorbs high potential energy made by process of accelerated motions effect of air spring by installation of inner air chamber. So, the application of VLCO can improve the efficiency of energy than that of wave energy converters made in Pelamis Company. In this research, experiments were performed for the models which have two different liquid column sizes. In order to find out the biggest motion response, two major conditions are taken into account. Two conditions are to open(or close) the valves and to differentiate the height of the liquid column.

In the phase of an architectural designing, the Pinakothek der Modeme in Munich is considered that it is influenced by the Altes Museum in Berlin. The critical elements were composed of the classification of Tominaka and my points of view. Two buildings were analyzed for comparison by six elements, such as, a spatial construction, an organization of plan, an organization of section, a composition of elevation, a method of construction and a composition of mass. The results of the analysis were that the design of the Pinakothek der modeme was influenced by the Altes Museum as follows: 1)the use of square and circle in the composition of plan, 2)the use of a curtain of columns and a formation of the transitional space between columns and front wall, 3)the location and function of the main stairs and the inner court, 4)the arrangement of exhibition halls, 5)the covering of dome, 6)the unification of spaces of different floors through the rotunda. This study may be helpful for any architects who make a decision of the method and the range of reference to some other building in the beginning of design.

This experimental research presents the seismic performance of steel reinforced high-strength concrete (SRHC) short columns. Eleven SRHC column specimens were tested under simulated earthquake loading conditions, including six short column specimens and five normal column specimens. The parameters studied included the axial load level, stirrup details and shear span ratio. The failure modes, critical region length, energy dissipation capacity and deformation capacity, stiffness and strength degradation and shear displacement of SRHC short columns were analyzed in detail. The effects of the parameters on seismic performance were discussed. The test results showed that SRHC short columns exhibited shear-flexure failure characteristics. The critical region length of SRHC short columns could be taken as the whole column height, regardless of axial load level. In comparison to SRHC normal columns, SRHC short columns had weaker energy dissipation capacity and deformation capacity, and experienced faster stiffness degradation and strength degradation. The decrease in energy dissipation and deformation capacity due to the decreasing shear span ratio was more serious when the axial load level was higher. However, SRHC short columns confined by multiple stirrups might possess good seismic behavior with enough deformation capacity (ultimate drift ratio ${\geq}2.5%$), even though a relative large axial load ratio (= 0.38) and relative small structural steel ratio (= 3.58%) were used, and were suitable to be used in tall buildings in earthquake regions.

The earthquake data(M$\geq$4.0) for post-1900 in the Korean Peninsula show temporal variation with active and quiet periods. The pattern is quite similar to northeastern China and Inner Zone of Southwest Japan. Yeongweol earthquake occurred in the seismic gap region of the Korean Peninsula. This is the first medium-size earthquake in inland region of the southern peninsula since 1978. The intensity based on the felt area estimation of about 400 places shows MMI III-Ⅷ in inland region. IIon Cheju Island and Ion Ulreung Island. The isoseismal of MMI Ⅶ shows an elongated circle in the direction of NE-SW and covers some parts of Jungdong-myon, Yeongweol-kun, Sindong-eup and Nam-myun, Jeongseon-kun. There occurred quite strong shaking, numerous cracks on the walls of buildings, falling and movement of slate and tiles on the roofs, falling of tiles from the wall and falling of materials from desks, rook falling from mountain and collapse of gravel lauers on the river side. The least square fitting of the intensity data of the Yeongweol earthquake by a popular intensity attenuation relation yields the following : I=Io＋1.82249 - 0.65295*InR - 0.00707*R

Recent abnormal climate change induces localized heavy rainfall and extreme disasters such as debris flow near urban area. Thus many researches have been conducted to estimate and prevent, especially in focus of physical behavior of debris flow. Even though it is hardly to consider overall related parameters to estimate the extent and degree of directly or indirectly damages due to debris flow. Those analytic restraint would be caused by the diversity and complexity of regional topographic and hydrodynamic characteristics of debris flow inside. We have utilized the Bayesian method to compensate the uncertainty due to the complex characteristics of it after analyzing the numerical results from FLO-2D and field measurement data. Revised values by field measurements will enhance the numerical results and the missing parameters during numerical simulation will be supplemented with this methodology. As a final outcome in this study, the risk index of debris flow damage will be suggested to provide quantitative estimation in terms of hazard protection including the impact on buildings, especially in inner and outer of urban area.
