Recently the problems related to the failure of the retaining wall structure has become great concern since the damage to the properties and human losses have occurred in the rainy season. However, a detail guideline on safety inspection and appropriate diagnosis on the retaining wall structure have not yet proposed and therefore, the inspection process and results are mainly dependant upon the engineers. The objective of this study is to propose objective and quantitative evaluation method for the condition based on the damage shapes and material types. In this purpose, composing materials of retaining wall are divided Into concrete, gabion, stone and reinforced earth, and then the evaluation items and method are suggested on the basis of the materials and structural characteristics of the retaining wall.

The main structural elements of historical masonry arch bridges are arches, spandrel walls, piers and foundations. The most vulnerable structural elements of masonry arch bridges under transverse seismic loads, particularly in the case of out-of-plane actions, are spandrel wall. The vulnerability of spandrel walls under transverse loads increases with the increasing of their length and height. This paper computationally investigates the out-of-plane nonlinear seismic response of spandrel walls of long-span and high masonry stone arch bridges. The Malabadi Bridge with a main arch span of 40.86m and rise of 23.45m built in 1147 in Diyarbakır, Turkey, is selected as an example. The Concrete Damage Plasticity (CDP) material model adjusted to masonry structures, and cohesive interface interaction between the infill and the spandrel walls and the arch are considered in the 3D finite element model of the selected bridge. Firstly, mode shapes with and without cohesive interfaces are evaluated, and then out-of-plane seismic failure responses of the spandrel walls with and without the cohesive interfaces are determined and compared with respect to the displacements, strains and stresses.

This study has been conducted to understand the relationships such as interspecific interactions between species and landscapes within and outside of agricultural land by identifying the flora features of Cornus officinalis farmlands in Gurye which designated as Korea's Important Agricultural Heritage System. For this, the flora of vascular plants was surveyed in every land uses of two representative districts. These two districts represent the own features of Cornus officinalis farming area which including land uses like forests(especially pine tree), valley, farmland(rice paddy, farms, Cornus officinalis farmland), and residence. Also differences in flora by stone wall's existence and Cornus officinalis's DBH were surveyed. As a result, Cornus officinalis farmlands showed the various vascular plants than the other land uses. According to the existence of stone wall in Cornus officinalis farmlands, there were no differences in appearance flora. But the flora in Cornus officinalis farmlands which have different Cornus officinalis' DBH(Divided into average over 15cm and under 8cm), various plants were showed in average over 15cm than average under 8cm. In conclusion, Cornus officinalis farmlands have been actively engaged in various types of land use and species exchanges, including forests, valleys, villages, and fields, and it has been confirmed that it acts as an ecological axis connecting forests to villages.

The purpose of this study is to analyze the way historical heritage was dealt with during the massive urban development period of the 1960s through the case of Deoksugung Palace. The wall of Deoksugung Palace was rebuilt and relocated in 1961. Later, it was rebuilt and relocated again in 1968, and Daehanmun Gate was soon moved back too. I analyzed the opinions of the Seoul Metropolitan Government, the Cultural Heritage Committee, experts and citizens that occurred during this process and reached the following conclusion. First, in 1961, the existing stone walls of Deoksugung Palace were rebuilt rather than restored and conserved for the urbanscape at the time. Second, in the 1960s, the Cultural Heritage Committee focused on the conservation of the origin of Daehanmun Gate, while citizens valued the overall harmony and function of Deoksugung Palace. Third, unlike the 1970s project led by the president to renovate national security and national defense sites, there was a call from citizens to realize the preservation of Deoksugung Palace.

창옥병의 지명 오류에 대한 문제의식을 바탕으로 고지도, 옛시문, 옛그림 등의 문헌자료조사와 암각 및 조망특성에 대한 현장조사 그리고 인터뷰를 통해 창옥병의 위치를 비정하고, 이곳의 향유주체인 사암 박순과 그가 경영한 배견와 및 별업 이양정의 공간 구조와 정원적 면모를 고찰한 결과는 다음과 같다. 창옥병은 옥병서원과 일체감을 갖는 공간역으로 옛그림과 고지도 그리고 암각문의 존재로 볼 때 옥병서원 바로 앞의 석벽임을 추정할 수 있다. 이 지역과 현재 창옥병으로 알려진 오가리석벽과는 직선거리로 불과 약 460m거리에 위치하고 있어 광의의 창옥병 경관영향권으로 볼 수 있다. 시문에 등장하는 "창옥병급산금(蒼玉屛及散襟)"이란 표현에서도 산금대라 암각된 병풍바위가 바로 협의의 창옥병임이 유추된다. 또한 오가리석벽에서는 단 1점의 암각도 확인되지 않는 반면 옥병서원 전면부 암벽 도처에는 사암 박순이 명명하고 주문하여 새긴 11개소의 암각 중 8개의 경물명과 제영시가 필첩(筆帖)처럼 밀집되어 있음은 옥병서원 앞의 강벽(江壁)이 의심할 여지없는 창옥병인 것으로 비정된다. '수월정신송균절조(水月精神松筠節調)'암각은 창옥병의 향유주체였던 사암의 고매한 인격과 덕행을 함축하는 창옥병의 상징언어이자 이곳의 장소 요체(要諦)로, 기존 알려진 것과는 달리 우암 송시열의 필적으로 바로잡아야 한다. 한편 사암의 정원유적 창옥병은 왼쪽으로부터 산금대-수경대-청학대-백학대의 4개 대로 구성되어 있다. 산금대 후면에는 본제인 배견와를, 백학대 좌측의 기암석벽 위에는 별업 이양정을 조성하여 멀리 오가리석벽의 장관(壯觀)을 관망하는 조망구도를 갖도록 계획되었다. 사대(四臺)) 좌측 가장 높은 곳에 입지한 이양정은 사암의 별업이자 독서처이자 장구지소(杖屨之所)이며 그 앞 너럭바위에 존재하는 와준(窪樽)은 사암의 술풍류를 반영한 정원시설로 비정된다.

With the accumulations of outcomes from archaeological excavations of mountain fortress of three kingdoms period, there have been studies about time-periodic territory range of mountain fortress, difference in the way(method) of construction, defence system and so on from various points of view. This is an empirical study on the construction method of the valley part of stone fortress. First of all, it is required to secure large quantity of fresh water for those who lived at mountain fortress. Especially when builders of fortress construct a fortification at the valley part of stone fortress, in advance they must sufficiently consider several options including the establishment of sustainable water resources. First, when it comes to build a fortification on a ridge[or a slope] of a mountain, you have only to consider a vertical stress. However, when it comes to build a fortification at the valley part of a mountain, You must have more sufficient preparations for the constructing process. Because there are not only a vertical stress but also a horizontal pressure simultaneously. Second, a fortification of mountain fortress built by using unit building stone is a structure of masonry construction like brick construction, and the valley part of it is where the construction of the fortification begins. Third, when it comes to build a fortification at the valley part of a mountain, it seems that they use a temporary method such as coffer dam in oder to prevent the collapse of the fortification due to heavy rain. Furthermore, in response to a horizontal pressure a fortification is built by the way of its plane make an arch, or by piling up the soil with the plate method(類似版築) and earthen wall harder method(敷葉) they increase cross-sectional area of the fortification and its cutoff capacity. In front direction they put the reservoir facility for the fear that the hydraulic pressure and earth pressure are directly transmitted to the fortification. The process of constructing the fortification at the valley part of a mountain is done in the same oder as follows; leveling of ground(整地) ${\Rightarrow}$ construction of coffer dam ${\Rightarrow}$ construction of the fortification between the both banks of the valley ${\Rightarrow}$ construction of the fortification at bottom part of spill way(餘水路) between the both banks of the valley ${\Rightarrow}$ construction of spill way(餘水路) & reservoir facility ${\Rightarrow}$ construction of the fortification at upper part of spill way between the both banks of the valley. Coffer dam facility seems to be not only the protection device on occasion of flood but also an important criterion to measure the proper height of spill way or tailrace(放水路). This study has a meaningful significance in that it empirically examines the method of reduction of the horizontal pressure which the fortification at the valley part of a mountain takes, the date the construction was done, and wether the changes in climate such as heavy rainfall influence the process of construction.

개성과 강화에는 다수의 고려왕릉이 남아 있다. 이 왕릉들은 전대의 능제적 전통을 이어받아 고려만의 독창적인 능제를 완성, 조선왕릉에 전승시켰다. 고려왕릉의 일반적인 특징은 우선 능역을 3~4단으로 구획하고 능제에 맞추어 각 단에 석물과 정자각을 배치하였다. 석실은 입구를 남쪽에 두고 있으며, 벽석은 수직으로 쌓아올렸고, 천장은 평천장이다. 석실바닥에는 중앙에 관대를 놓고, 그 주변에 전돌을 깔았다. 벽면과 천장에는 회칠을 하고 그림을 그렸다. 그런데 석실내부의 구조를 자세히 살펴보면, 이런 일반적인 특징 외에 몇 가지 세부적인 차이가 발견된다. 고려초기에는 1단 평행고임천장과 통돌관대, 유물부장대 그리고 식물소재의 벽화가 조합되어 나타나며, 이는 과도기적 형태를 거쳐 12세기후반을 기점으로 평천장, 장대석재벽석, 석주형석재조립관대로 변하고 있음을 알 수 있다. 한편, 몇몇 왕릉은 출토된 시책(諡冊) 편을 통해 능주를 명확히 규정할 수 있으며, 석실내부에서 출토된 청자는 해당 왕릉의 축조연대와 상당한 시기차가 있음을 확인할 수 있었다. 이점은 도굴 등 왕릉의 파괴로 인한 후대 보수과정에서 당대 유물이 매납된 것으로 판단된다. 마지막으로 기록상 왕릉의 장지방향과 발굴결과를 비교검토하여 능주가 누구인지를 추적해 보았다. 그 결과 충목왕명릉 등 일부 왕릉은 능주의 비정이 잘못되었음을 확인할 수 있었다.

This study aimed to elucidate the architectural characteristics of the cathedral architecture of the Archdiocese of Gwangju, which was completed in the period of liberation and turbulence, and the conclusions are as follows. Gwangju Archdiocese Cathedral, completed during the period of liberation and turbulence, was built with some assistance from the U.S. military or with the efforts of the faithful, and there are a number of factors such as space directing by Aps, the development of a simplified bell tower, the appearance of a stone cathedral, the application of a quenset structure, and an increase in size. show special features The indented apse appears only after liberation, and is a characteristic that appears prominently in stone churches. The simplified form in which the bell was hung by raising the outer wall appeared in the early church shows a change in the composition with a porch in front. The stone church and the quanset-structured church only appeared after liberation and were built only in the 1950s. The size of the cathedral reflects the increase in the number of believers after the Korean War, and the average area is about 1.5 times higher than before liberation. When considering the spacing of the bays as a module, the size plan followed the implicit norm of early cathedral architecture of 36.5m, but gradually decreased to 2.7m and 2.4m.
