The historical exchanges between the Republic of Korea and Japan have broadly occurred, in terms of both political and cultural aspects, from ancient to modern times. Regarding ancient gardening culture, in particular, Asuka developed gardens with the gardening techniques passed down by the Baekje people. The development of the basic form of a garden pond along with its characteristics, established through such exchanges, is suggested by investigating its components through analysis of data from the gardens of Baekje and Asuka. In terms of the garden pond structure, homogeneity was confirmed between Baekje and Asuka, with a linear rectangular form as the basic design. In addition, the vertical construction technique was used by both ancient kingdoms. In terms of the types of stone used in building the shore of the garden pond, Baekje used diverse types such as natural stone, crushed stone, and cut stone. In contrast, rounded river stone was used by Asuka. Regarding the floor of the garden pond, Baekje used soil, which enabled the planting of lotus flowers. In contrast, Asuka used stones to pave pond floors, which made the growth of plants impossible. In terms of layout, Baekje used ornamental stones for pond landscaping, while Asuka used manmade island and water intake facilities in their pond construction. The effects of Baekje's garden culture on Asuka's garden building can be seen from its influence on the form of the garden pond and shore construction style. In terms of the construction of the garden pond's shore with the same stones and the stone flooring, the garden ponds of the Asuka Kingdom reveal technically unified and refined aspects.

The present work investigates the behavior of the embankment models resting on soft soil reinforced with ordinary and stone columns encased with geogrid. Model tests were performed with different spacing distances between stone columns and two lengths to diameter ratios (L/d) of the stone columns, in addition to different embankment heights. A total number of 42 model tests were carried out on a soil with undrianed shear strength $${\sim_\sim}10kPa$$. The models consist of stone columns embankment at s/d equal to 2.5, 3 and 4 with L/d ratio equal 5 and 8. Three embankment heights; 200 mm, 250 mm and 300 mm were tested for both tests of ordinary (OSC) and geogrid encased stone columns (ESC). Three earth pressure cells were used to measure directly the vertical effective stress on column at the top of the middle stone column under the center line of embankment and on the edge stone column for all models while the third cell was placed at the base of embankment between two columns to measure the vertical effective stress in soft soil directly. The performance of stone columns embankments relies upon the ability of the granular embankment material to arch over the 'gaps' between the stone columns spacing. The results showed that the ratio of the embankment height to the clear spacing between columns (h/s-d) is a key parameter. It is found that (h/s-d)<1.2 and 1.4 for OSC and ESC, respectively; (h is the embankment height, s is the spacing between columns and d is the diameter of stone columns), no effect of arching is pronounced, the settlement at the surface of the embankment is very large, and the stress acting on the subsoil is virtually unmodified from the nominal overburden stress. When $(h/s-d){\geq}2.2$ for OSC and ESC respectively, full arching will occur and minimum stress on subsoil between stone columns will act, so the range of critical embankment height will be 1.2 (h/sd) to 2.2 (h/s-d) for both OSC and ESC models.

Demand for stone products used as building materials is increasing. The construction industry, the value of the stone industry is sufficient, but the domestic stone industry is very lag regarding IT utilization. However, the overseas stone industry produces high-quality products using IT. In this study, we want to offer an IT application technology priority fit for the stone industries. We identify the current status and production process of the stone industries, then set the priority of various IT, so that obtain competitiveness in the domestic stone industries, and minimize the gap between the overseas stone industries. Therefore, we used AHP method; stone industry production processes were selected as the Enterprise Operation Management, Quarrying, Manufacturing, Construction and Maintenance of first-tier. The second-tier ones are consisted of 30 factors out of IT elements. Focus group interviews were conducted to confirm the validity of each factor. As a result, most important factors of first-tier was selected as the order of Manufacturing, Quarrying, Enterprise Operation Management, and Construction & Maintenance. The top 5 of 30 factors in the second-tier were selected Smart Sensor, Mobile Device, Robot of manufacturing, GIS of quarrying, and SCM of enterprise operation management. And the factor that relatively less important was GPS of construction and maintenance. If properly applied an IT application technology for stone industry, we expect to provide efficient production lines and increase customer satisfaction, which will ultimately expand the promotion for the industry and thus act as positive factor in promoting the stone industry.

본 연구는 광화문 월대로 사용된 석재를 대상으로 암석학적 연구를 활용한 석재공급지를 추정하기 위해 수행되었다. 월대는 2010년에 일부 구간이 다시 복원된 것으로 원부재인 담홍색 화강암과 신석재인 회백색 화강암이 사용되었다. 석재공급지 추정을 위해 북한산과 수락산의 지질조사를 수행하였으며 채취한 시료는 모두 담홍색 화강암과 유사한 특징을 보였다. 전암대자율은 북한산에 비해 수락산의 값이 크고 암석의 색에서 부분적인 차이를 보이지만 수락산이 상대적으로 선명한 담홍색을 띤다. 수락산은 월대에 사용된 원부재와 비슷한 암석기재적 특징, 전암대자율, 역사적 사료 그리고 야외조사 시 발견된 채석흔적 등을 통해 최종 복원용 석재공급지로 판단된다. 물성시험 결과, 월대 원부재는 풍화로 인해 147 MPa로 다소 낮은 수치를 보이며 석재공급지로 생각되는 수락산은 244 MPa 높은 값을 보여 안정성까지 확보되어 양질의 석재로 사용 가능하다. 수락산 일대는 주거지역이 일부 포함 되어 있어 행정적인 문제, 자연파괴, 인근 주민 생활권 침해가 발생하여 채석활동은 어렵다. 또 다른 대안으로 QAP조성, 광물조직, 암색 등의 암석학적특징 및 물리적 특성까지 유사한 중-조립질 담홍색화강암의 포천 창수석과 영중석을 제안할 수 있다.

The high-rise and high-density apartment complexes are built on a large scale and occupy a large portion of the city. The facade of the apartment has a great influence on the cityscape. In particular, the lower part of apartment design gives people to important impressions. For the harmonious landscape of the city, the color plan emphasizes its importance as an influential visual design element that forms the urban landscape. In specialized apartment design, especially finishing material on lower-parts of apartment which is recognized by pedestrian is more important planning factor. Also, finishing material which is one of the primary design elements is important for making the entire image about the building with color. Nowadays stone is mostly used for specialized design on lower-level in apartments. Stone makes luxurious image and harmonious landscape as a nature material. But when planning for design, only general stone graphic or pictures is used without specific plan, after construction, there is a big difference between a plan and the actual color and image. Thus based on exact understanding of stone, I analyzed current state of expression for stone which is used for lower-parts of apartments in Daegu. By this, the purpose of this study is to present detailed data to offer the basis for planning specialized design of lower-parts of apartment.

This paper is to clarify on the characteristics of the Haeeumwonji and the Main Palace of the Goryo Dynasty. The architectural techniques and construction methods such as embankment, stylobate, stairway, foundation stone, and pave are similar to those of the Haeeumwonji and the Main Palace of the Goryo Dynasty. In order to express the hierarchy of the area and building, the materials, techniques, and forms of the embankment, stylobate, stairway, foundation stone and pave were used differently. The paving of the floor of the main building and area is also an active expression of the hierarchy and status of the building area and the building through the use of building materials, techniques and forms. This result confirms the support of Goryeo royal family and the upper class for the construction of Haeeumwonji, which is recorded in the historical documents. And it also shows that the architectural techniques and processing method of the same period were shared in the capital and provinces, which is an important clue that proves that the capital-centered architectural technology has spread to the provinces. It is expected that additional research will be needed on the characteristics of the period of 12th century architecture technique in which Haeeumwonji was built.
