  • This study aims to measure and to analyze the thermal environment characteristics of the various permeable pavement materials such as grass pavement (GREEN BLOCK PARK), stone and grass pavement (GREEN BLOCK STEP), stone pavement (GREEN BLOCK MOSAIC) and wood pavement (WOOD BLOCK) under the summer outdoor environment. The thermal environment characteristics measured in the study includes the changes of surface temperature during the day, changes of the temperature on each pavement layer, and long and short wave radiation of each pavement surface. The experimental condition is based on the data on the hottest temperature (August 5, 2005, $34.0^{\circ}C$) of the you. Some of main findings are: 1) The heat environment was worse on the wood pavements than on the stone pavement. This is mainly due to the low albedo of the wood pavements (0.37) while the albedo value of stone pavements is 0.41. Small heat capacity of the wood pavements also contributes to this difference. 2) The heat environment was worse on the stone pavements than on the turf pavements. This was mainly due to the evapotranspiration of the plant growth layer of the turf pavements. 3) The peak surface temperature was the highest on the wood pavements ($56.1^{\circ}C$). The peak surface temperatures on the stone pavements, the stone-grass pavements and the grass pavements were $43.1^{\circ}C,\;40.1^{\circ}C\;and\;37.9^{\circ}C$, respectively. 4) To improve the thermal environments in the urban area, it is recommended to raise the albedo of the pavements by brightening the surface color of the pavement materials. Further studies on the pavement materials and the construction methods which can enhance the continuous evapotranspiration from the pavements surface are needed.

  • Formative and structural characteristics of stone pagoda in Jeonnam area are known in largely two flows. One is that characteristic of stone pagoda in Jeonnam area of the Unified Silla is shown in eastern Jeonnam and some southern Jeonnam. But it is not shown in surroundings of Yeongsan river. Another is that besides stone pagoda in Silla style where social aspects of Goryeo are reflected, stone pagoda in Baekje style appeared. On the other hand, stone brick pagoda and non-typical stone pagoda appeared. These stone pagodas were developed mainly in north and west of Jeonnam, and could be classified in pure Baekje style and a cross style according to formative and structural characteristics. Stone brick pagoda is extant in Wolnamsa site and Woonjusa in Chungcheong and Jella areas which are old places of Baekje.

  • This study identified the materials and construction methods of 'Old Wall' in 13 villages which were designated as National Registered Cultural Heritage at the time of designation and examined the their structural changes based on field survey. The results are as follows: First, the 'Old Wall' consisted of 10 Soil-Stone Wall and 5 Stone Wall. At the time of designation, Stone Wall, which was built irregularly by dry-construction of natural stones, is similar in shape, but Soil-Stone Wall showed difference by the construction method of making used stones, joints, and faces. Second, the study extracted the changes of 'Old Wall' by repair and examined the changes of construction methods as well as the substitution and addition of materials of structure. The wall-roof was built with cement roof-tile and asbestos slate which have the advantage improve durability and cost-effectiveness. In addition, tile-mouth soil was added to korean traditional roof-tile to prevent rainwater from flowing in. Besides, to improve constructional convenience, the natural stone of the wall-body was replaced with blast stone, float stone and cut stone. Cement block, cement brick and cement mortar were frequently used to repair as well. As Soil-Stone Wall was transformed from irregular pattern-construction to comb pattern-construction and wet-construction was changed to dry-construction, it caused landscape and structural problems. Also, the layer of cement mortar applied to wall-foundation blocked the flow of rainwater that was induced by dry-construction of natural stones. Third, the study regarded that the problem with the repair of 'Old Wall' may occur as it is located in living space, because the owner of the wall could repair for the minor damages without technical knowledge. In addition, it is difficult for repair companies in charge of maintenance of Cultural Heritage to supply local materials, and it is differential construction specifications are not applied.

  • The purpose of this paper is on identifying spatial structure of Palwang and Taechon village and dealing with restoration direction of village spatial structure and village groves. The results are as follows. It was identified that the standing stone for penis form is not standing stone for praying son but complementing that for enforcing enclosed function of enclosing village groves. It was considered that village entrance and entrance road, village grove of Taechon village must be restored for being identified as standing stone of penis form of spatial structure of village. It was considered that the above is essential to connect with ecotourism of Sunchang-gun region. It was identified that Palwang village grove is very good in conservation state, but Taechon village grove has been destructed mostly by various development. It was identified that Palwang village grove is high in species diversity and in scare value as mixed forest, landscape value. The dominent tree of Palwang village was Pinus densiflora and that of Taechon was Salix glandulosa. Salix glandulosa was used pavilion tree, main tree in both village. It was identified that Carpinus tschonoskii is showing the most rapid growth in tree height and Salix glandulosa is showing the most rapid growth in tree breadth diameter of all kind of tree. It was considered that Pinus densiflora was planted first of all and deciduous trees were complemented later. It was considered that simple forest of Pinus densiflora has been changed into mixed forest by artificial affect in the long term. It was considered that Salix glandulosa in Palwang village grove must be indicated as legal protection tree according to present criteria of protection tree selection in Korea. And it is considered desirable that standing stone of penis form and village grove in Palwang village must be indicated unitedly as cultural conservation element.

  • The purpose of this study is to analogize the appearance of Korean Ancient Architecture in view of the Stone Remains from 3 Kingdom Period to Unificated Shilla Period. But in these period, there is no building remains but some stupas and fine arts. Especially, there are many architectural appearance and revealing signature in these Historical Stone remains. Architectural elements which are analogized by stone remains what has value as historical materials by preservation of original form from 3 Kingdom Preiod to Unificated Shilla Period are as follows : 1) Platform, the representative characteristic of Korean traditional architecture, was frame structure and accumulate structure. And circular or square footing stood a same shape column on it is put on the platform. 2) In the case of column, there used entasis column and inclined column and circular chamfer technique was applied on the top side of it. Upper side of column, capital and head pentrating tie that small bearing block was put on the center of it was joined. And longitu야nal rest(長舌) supported a cross beam. Capital and small bearing block had no bottom heel, and heel side was curved and straight. Centered bracket structure was often used, and multi bracket structure is not used yet. Inward incline technique was used. 3) Inward opening pair door which had lintel, threshold, doorjamb was usually used, Fixing stone was used for structural safety, and circular handle and lock was used for decoration. Handrail was used on the edge of wooden floor for decorative effect and safety. 4) Square rafter and circular rafter were used in the same period and so did flying rafter. Double eaves and single eave were used in the same period but, single eave was usually used. In this period, square rafter was usually used. This would be studied more by comparing with Japanese wooden architecture. 5) Hipped roof was used and half-hipped roof was not used yet. In front of th hip, there are small sculpture called Jap-Sang(雜像), and windbell was hang on the end of the hip rafter. Concave roof tile, convex roof tile, round eaver tile, decorative tile at end of roof ridge were used. Lotus style was well used on the face of roof tile for decoration. From the results of this study, wooden architecture of Unificated Shilla period was simple compare to Koryo dynasty and Chosun dynasty but, it had some brilliant character. It was hard work that analogized the form of non-existent wood architecture of Ancient Korean period by restricted stone remains. But, in addition to the results of this study and research of old documentations, more study should be go on.

  • Stone is one of the oldest material for construction and artistic works. This study investigates the current use of stones in landscape constructional works, and the design criteria to advance the arts of natural stone arrangements. Thirty four experts and thirty two others were surveyed with various photos of simulated construction works of natural stone arrangements fond improved design guidelines. Major findings are as follows: -The payment for the use of stones ranges approximately 5 to 10% of total cost of landscape constructional works. More stones may be used when better retailing system is introduced, working skill is standardized, and more of the substitute natural stones made of blasted rocks are provided and the cost goes down. -Preferences showed little difference for the mixed use of different sizes, colors and shapes of stones, and for the use of similar ones, in the construction of walls. This does not match with the current design guidelines. -Arranging three stones, which symbolizes heaven, earth, and human being, was the most preferred. As the supply of natural stones is limited and more substitute stones are used, it its needed to establish guidelines for the production of substitute stones. -Grasses are much more preferred between pavement stones than mortars. -In current practices, top of piled up natural stones is usually arranged level. More freely curved top lines are preferred to straight line.

  • It is important to consider urban parks and greenery not only from the viewpoint of amenity or aesthetics but also from the viewpoint of biodiversity. In this study, we focused on bryophytes (mosses), and analyzed how existence of artificial structures in urban greeney, such as concrete curbs and stone walls, affect species diversity of bryophytes. Kyoto Gyoen in Kyoto City, western Japan, was selected as the study site. In consideration of kinds of substrates on which bryophytes grow, microhabitats of Kyoto Gyoen were divided into ten types including concrete curbs and stone walls. In each type of microhabitats, we selected the area where bryophyte diversity was highest, and established a quadrat for bryophyte flora survey. Our results showed that the number of bryophyte species and growth forms and the value of diversity indices on concrete curbs or stone walls were higher than the averages of those. The bryophyte species were divided into the four groups by TWINSPAN as follows: Group A (epiphyte species), Group B (rocky species), Group C (roadsides, grassland or forest species), and Group D (waterside species). Bryophytes classified into Group B (rocky species) were mainly recorded on concrete curbs or stone walls. It was considered that the existence of artificial structures (concrete curbs and stone walls) provided favorite habitats for the bryophytes classified into Group B (rocky species), which mainly grows on concrete or rocks, and enhanced species diversity of bryophytes in Kyoto Gyoen.

  • The place of South Weol Dynastys authorities exhumed in the region of KangChoWu, China lies adjacent to a stone ditch through which water streams crookedly, and a dark trough of stone pond in the north side. There is a sharply curved stone ditch and a crescent-shaped water entrance made by stones. The place was separated by using stone columns and stone walls. There is a beam of ditch, a crooked entrance, a flat bridge of slate, a stepping-stone, a sluice gate, and a crooked corridor. There are big and small artificial islands, and reinforcing stone drainage way in the palace pond recently exhumed at the building site for the pavilion of Hwang-Yong Temple in Kuhwang-Dong, Gyeongju city, Korea. There are four facilities assumed to be entrance and exits at four corners and an open space on which gravel was spread extensively. A narrow road and a middle road with indefinite curves at the south of Asukakyoseki exhumed by the first, second and third and two stone buckets which one is to fill with water and the other is to drain water off like fountain are there, and besides wave protecting dam and north pond and the part that water pass were excavated. Palace ponds that were extensively distributed at old residential cities are a general phenomenon of countries in eastern Asia. Anap pond of Silla and Gungnam pond of Baekje were in Kroea. We believe that Asutnkyoseki is on the extension. Although more investigations in the background of thought and the genealogical relation about the palace pond are required, it seems that an idea was surely received from China.

  • 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.

  • In this study, the following conclusions were drawn by analyzing the size, proportion, shape, angle, distribution, etc. of stones in order to identify the principles of facade molding of stonework of the 5th to 7th centuries of the Silla Dynasty. First, the uniformity of the size of the stones of the stone foundations of the Silla Dynasty was low at -0.8 to 4.1. This means that stones of various sizes were used, from small stones to large stones. In addition, the distribution of large stones in stonework of the Silla Dynasty appeared evenly regardless of height. This was common in the stonework of the Silla Dynasty, regardless of structural classification such as wells and mountain fortresses. It is thought that the Silla people did not only pursue practicality and efficiency in stone construction, but also considered design elements. Second, the proportional deviation of the stones of the stone walls of the Silla Dynasty was high, ranging from 0.861 to 1.515. This means that the stonework of the Silla Dynasty did not use only long flagstone-shaped stones, but used a mixture of long and short stones. Third, the shape average of the stones of the stonework of the Silla Dynasty was low at 0.45, and the shape deviation was high at the maximum of 0.15. This means that the stones as a whole have irregular shapes, and each stone has a high difference in shape. Fourth, the angle deviation of the stones of the Silla Dynasty was 4.3 to 16.2, and the average angle was 2. This means that the angle of each stone on the stone axis of the Silla Dynasty is tilted to the left and right. Fifth, there was no correlation between stone size, slenderness ratio, shape, and angle in the stone axes of the Silla Dynasty. In the case of stone axes in the Joseon Dynasty, there was a positive correlation between stone size and slenderness, and a negative correlation between stone size and shape. It can be said that the stones of the Joseon Dynasty were relatively standardized, but the Silla Dynasty showed the beauty of moderation by keeping the nature of the material and becoming one with the material.
