Local scour is associate with particular local types of vortex around bridge piers. This paper is method of protection local scour for the existing Busan City subway 3 Line bridge piers and Gupo large bridge piers. In order to take design of protection of local scour this bridge piers, We calculate the local scour hole of depth , scour width, riprap construction , filter construction by formulas. We had experimental hydraulic model test for this bridge piers in order to take proof for the calculation of local scour. We knew that the vortex intensifies the local flow velocities and acts to erode sediment from the scour hole and transport it downstream. As the result of hydraulic model test, we could suggest three types method of protection local scour this bridges. We knew that FHWA HEC-18(Richardson et al. 2001: Modified CSU) Formula is useful to checking calculation as application of field. One is pier protection using the sheet piles and riprap, the others are pier protection using the riprap with filter and to make renew Wall-caisson. The best method of protection for the existing Busan City subway 3 Line bridge piers and Gupo large bridge piers is pier protection using the sheet piles and riprap.

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.

Since its construction in the late 14th century, Hanyangdoseong had been carried out three major repairs and reconstructions during the 500 years of the Joseon Dynasty. In addition to the large-scale construction, small-scale construction continued until King Gojong era. In particular, in the 18th century, systematic construction management was implemented by the craftsmen and the military participated in the renovation of Hanyangdoseong in earnest, and the construction methods also developed rapidly. In the early 18th century, new construction techniques were attempted in various sections of the reconstruction work, and gradually became a common technology for repairing Hanyangdoseong in the late 18th century. The purpose of this study is to examine the characteristics and period of changes in the 18th century's construction technique, when the rapid development of Hanyangdoseong took place. To this end, the excavation results related to Hanyangdoseong, the remaining city wall, and the inscribed stones were used to identify and demonstrate the characteristics and change of the construction method.

Due to the rapid process of industrialization the cities of Korea confront changes of climate, destructions of the habitate and decrease of the green. Recently Seoul and other local governments have implemented policies and projects to improve the environmental surroundings. In reality, however, those policies and projects face difficulties in the course of implementation. The fact that there are no concrete regulations and specific legal procedures turns out to be one of the main difficulties. The aim of this study is to present specific plans and methods of wall-planting and to provide basic guidelines for the future direction of wall-planting and offer ideas of facilitating wall-planting. This study is based on questionnaires from specialists of landscape architecture through individual interviews and/or e-mails. The questionnaire is consisted of following 4 sections. 1. Show the experts current regulations and/or legal procedures and ask them improvements and suggestions. 2. Ask them choose matters of the highest priority by using Ricardo's diagram method. 3. Ask them to make a graded list in terms of the location and method of wall-planting. 4. Study the maketability of the wall-planting products currently in circulation. The city of Seoul and the Ministry of Environment recommend that trellis and/or planting inducement structures be installed on the building wall by regulation. The specialists responded to the questionnaire advocate that green wall without trellis should be allowed as green zone. Therefore regulations concerning the wall-planting should be determined specifically according to the characteristics of individual plants and walls. It has been urged that legal aid and social support must be reinforced to establish rules dealing with wall-planting. The respondents also point out that significant cutting down of the tax is far more effective in accelerating the wall-green instead of administrative support. The highest priority in terms of planting has been given to sound-proof wall, retaining wall and building wall. Concerning the maketability of the wall-planting products, panel products are recommended for early-planting and building planting. It has been suggested that the research and study of new materials and species be done in advance.

스크류잭은 스트러트에 충분한 선행하중을 가할 수 없기 때문에 스크류잭을 이용한 버팀대공법은 주변지반의 변위를 억제하는데 효과적이지 못하다. 따라서 버팀 굴착시 주변지반의 과도한 변형을 방지하기 위하여 새로운 선행하중잭을 개발하였다. 본 논문에서는 새로 개발된 선행하중잭과 그 장치를 이용하여 시공한 현장 중 3곳에서 측정한 흙막이벽체의 수평변위에 대한 결과를 소개하였다 현장에서 계측한 결과에 의하면 흙막이벽체의 최대수평변위는 굴착심도의 0.15% 이내로, 스트러트에 가해지는 선행하중에 의하여 최소화될 수 있는 것으로 밝혀졌다. 그리고 경제성 분석을 위하여 스크류잭을 이용한 버팀대공법과 버팀대 선행하중공법에 의한 공비와 공기를 비교한 결과 버팀대 선행하중공법이 공사비와 공사기간의 단축에도 효과적인 것으로 나타났다.

This study compares, analyzes and reevaluates color conditions and images before and after the execution of the 7th curriculum with elementary schools in Gwang-ju Metropolitan City based on the fact that color among physical environments of elementary classrooms has an important influence on children's emotion and draws problems and aims to accumulate the basic materials for preparing guidelines of improving color environment at general classrooms of elementary schools. Consequently, according to color conditions, major colors on ceiling and wall were high brightness/nigh chroma of Y and YR line regardless of division of grades and other color factors of classroom showed that wall and ceiling used similar colors, but brightness was higher after change than before it. In evaluation of color images, lower grades showed negative color images such as 'common,' 'rustic,' and 'strange' before change, but they showed positive color images after change such as 'clean,' 'unique,' and 'soft'. But, most of higher grades showed negative reactions before change such as 'common,' 'strange,' and 'rustic' and they showed positive reactions after change only in such items as 'clean,' 'warm,' and 'unique', but Indicated negative reactions in remaining items such as 'strange,' 'rustic,' 'stiff,' and 'artificial'. Accordingly, in using colors for lower grade classroom, arrangement of colors through adjustment of brightness and chroma between ceiling, wall and other components based on coloring of high brightness and low chroma of similar colors should be considered and for higher grade classroom, arrangement of colors of unique images of mid-brightness/mid-chroma among warm color lines of similar colors should be examined.

In June, the City of Seoul held a design competition for $\ulcorner$Seoul Park$\lrcorner$in Paris to promote friendly relations with its sister city. The purpose of this paper is to articulate the design concept of a scheme submitted by the author. The author interpreted the object of this design competition as follows: if we regards a park not as one of urban planning facilities but as a space for expressing a culture, $\ulcorner$Seoul Park$\lrcorner$in Paris is a space expressing Korean culture, or a culture of the City of Seoul in Paris, France. Three points were emphasized in this scheme: 1. Physical and non-physical aspects of Korean culture, or a culture of the City of Seoul were expressed separately. In physical part, a traditional Korean garden was reappeared to express its authenticity compared to its counterpart, French classical garden - its formal and grand style. In nonphysical part, Seoul's features and its citizen's facial expression were engraved on 'free standing walls' named 'Seoul Expression'. In addition, Korean traditional and modern performing arts will be performed in a square named as 'Seoul madang' surrounded by the free standing walls. 2. A space clearly divided by the fence was necessary to distinguish a traditional Korean garden from the place which looks like an amusement park. Traditional wall, mounding and pine tree groves were included. 3. Bamboo grove with the way taking a walk was introduced. The author expected that Parisian feels oriental mystery, the sound of wind, and the time lag of past and present in this sounding bamboo grove.

안창리 유적지에서 출토된 기와를 대상으로 제작기법을 추정하기 위해, 기와 9점과 벅체 5점을 대상으로 하여, 실제현미경관찰, 편광현미경관찰, X-선 회절분석을 실시하였다. 기와를 제작할 때, 성형을 위해 비짐을 첨가하는 대신 기존의 기와편 등을 잘게 부셔 넣은 것으로 보인다. 철분이 많은 미세한 덩어리나, 폐기된 벽체 등에서 얻은 재료를 재활용하여 비짐으로 사용(chamotte)한 흔적이 기와 및 벽체에서 흔히 관찰된다. 또한 어떤 것은 chamotte 내에 다른 chamotte가 들어 있어 수차에 걸친 재활용도 이뤄졌을 것으로 보인다. 구성광물 조합에서 추정한 기와와 벽체의 소성온도에 따라 저온형($800^{\circ}C$ 이하), 중간형($800-930^{\circ}C$), 고온형($930^{\circ}C-1470^{\circ}C$)으로 분류하였다. 그 중에서 가장 고온에서 소성된 것은 조선시대의 것인 A8과 AW5로 판단된다.

What is Art on the street? Is it a series of artworks or activities performed on the street? In other words, does "art on the street" refer to "Street Art" such as street performance, happening, graffiti, or wall-painting, or does it refer to "Street Furniture" which is related to "City Design" or "Environmental Design"? In a formal sense, they all belong to Art on the street. However, in this paper, I would like to use Art on the street in an even broader sense. To me, " the street" is a metaphor of "environment." Thus Art on the street is the art related to environment; it is an environment art. Art on the street attests the expansion of the concept of art and shows a new possibility of contemporary art. It is a promising new concept of art, but we cannot ignore the misapplication of the concept that we can find at the crossroad of Art on the street and "city beautification." Of course, Art on the street can and sometimes needs to beautify the city. However we still need to ask how to contribute to the city beautification with Art on the street and how to validate such a practice. City space is, most of all, a space that people live in. It sounds a cliche, but it is worth repeating to better understand Art on the street. When we consider the city space in terms of its system or organization, we often overlook that it is the space in which people live, and which people create. Art on the street concerns not the city itself, but the space in which people live and make relations for each other. Without taking this into account, Art on the street becomes a mere means to' embellish' the city and falls prey to the logic of capital. In this paper, I critically reviewed the problems such as City Development, Spectacularization, City Environmental Design, Public Interest and City Museum. I intended to emphasize that Art on the street is produced in the cultural space of city, but it also tends to break the mold of the cultural space and seeks a new possibility. Some might argue that my claims are unrealistic because Art on the street is not an idea but a practice. While humbly accepting the objection, I hope my critical suggestions guide a more productive direction to continue our discussions of Art on the street.
