본 특집은 지방시대에 지역건축문화가 어떻게 변화하고 정착되고 있는가? 그 지역만의 갖고 있는 도시+건축문화의 아이덴티티는 무엇이고, 현대화과정에서 그 지역의 고유한 문화경관요소가 개발과 보존이라는 병립된 사회요구속에서 어떻게 적응되고 있는가에 대해 살펴봄을 의도하고 있다. 특히 백제문화권의 중심도시인 아산, 부여, 공주의 도시특성을 이루고 있는 도시공간구조 및 구성요소와 그 속에 내포되어 있는 문화경관요소의 현황을 살펴본다. 본고는 현대화하는 과정 속에서 전통성이 있는 문화요소를 지역성의 개념과 상관적으로 관련시켜 정리하기 위한 것이다. 문화가 지역을 초월하여 국제적으로 교류되면서, 생활의 편익성을 추구하는 현대인들은 국가와 민족의 차이를 넘어 동일한 지구문화형성의 과정으로 급속히 진행하고 있다. 현대화는 서구화라는 등식은 서구문화의 간결한 편익성이 낳은 전세계적 현상이다. 따라서 현대화를 생활의 변화로 이해할 때에 전통논의의 여유가 있고, 전통논의에 대한 객관성이 있으며, 편협된 전통관으로부터 자유로와질 수 있다. 시간의 변화에 따라서 생활이 변하고, 특히 생활을 담는 그룻으로서 건축환경이 변한다. 오랜 시간을 통해서 서서히 건축환경이 변하지만, 누적된 변화는 커다란 차이로서 나타나고, 이에 따라 적응과정에서의 여러 문제점이 발생한다. 그러므로 현재까지 많이 논의되어온 보전과 보존의 방법론적 세분화에 의한 적극적인 대책이 요구되는 시점에 있다고 할 수 있다. 해서 '전통성을 갖춘' 도시ㆍ건축구조물을 단순한 유적, 유물로 보존할 것인가, 실생활과 관련된 생활과 함께 하는 문화현상으로 적응시킬 것인가 하는 문제점이 우리의 과제인 것이다.

In Seoul, structural deterioration is severe in the private masonry buildings which have been built since 1906s. But most of these structures remain without any repair works. As a result, the rate of deterioration is getting faster and these dangerous structures may cause hazardous circumstances to the adjacent structures and neighborhood. The purpose of this study is to investigate the actual conditions of wall cracks among the defect types which occur in private masonry buildings and to analyze the correlation between safety grades and wall cracks for offering the fundamental data. Using these date we can establish basic criteria for safety grades of structures and improve the quality of masonry buildings. The result of this study indicate that there are high correlations between safety grades and the width of crack but much less so with the length. Furthermore, with regard to crack patterns, vertical cracks much more negatively effected the safety grades.

Kriging is widely applied to dealing with the spatial distribution of rainfall, however its prediction results are different according to the selection of variogram type. This study investigated adequate variogram for daily rainfall. The comparative results show that kriging prediction with covariates is better than that without covariates. The Mat$\acute{e}$rn correlation function, which is the most general type variogram, is recommended if adequate variogram is difficult to determine.

본 연구에서는 국내 주요 종관기상관측장비(Automated Surface Observing System; ASOS)의 강수 자료에 CSEOF 분석(Cyclo-stationary Empirical Orthogonal Function Analysis)을 적용하여 주요 성분(principle component)을 추출한 후 이를 분석하여 국내 강수의 계절적 순환 특성을 평가고자 하였다. ASOS 자료로는 전국 131개의 ASOS 중에 40년 이상의 월 강수량 자료가 구축되어 있는 47개 지점의 자료를 이용하였다. 수집한 자료의 기간은 1978년부터 2018년까지이다. 강수 자료의 월별 공간적인 강수 분포 특성을 파악하기 위해 시간적인 순환성을 고려한 CSEOF 분석을 수행하였다. 강수자료의 주성분을 추출해본 결과, CSEOF 분석의 경우 첫 번째 CSEOF 외의 다른 CSEOF들의 원자료 설명 비율 또한 작지 않게 나타나 다양한 강수 변동 특성을 평가할 수 있음을 확인하였다. 8월의 2nd CSEOF는 한반도 전체의 강수가 감소하는 것으로 나타났으며, 이는 라니냐가 7-8월 한반도 강수에 미치는 영향과 유사하다. 아울러 9월의 2nd CSEOF 결과 또한 남부를 중심으로 전체적으로 감소하는 경향이 나타남. 이는 엘리뇨 발생 시 9월의 강수 패턴과 비슷한 것으로 확인되었다. 뿐만 아니라, 우리나라에 영향을 미친 주요 태풍과 CSEOF의 상관관계도 검증할 수 있었으며, 장마와의 관계도 발견할 수 있었다. 향후, CSEOF 분석 결과에 해석방법이 개발된다면, 보다 다각적인 측면에서의 강수 계절적 순환 특성 평가가 이루어 질 수 있을 것으로 기대한다.

콘크리트 충전 강관기둥부재(이하 CFST)는 대칭성을 유지하는 기하학적 특성과 내부에 충전된 콘크리트의 구조 및 내화성능의 향상으로 최근 초고층 건축물의 주요 요소로 활용되는 추세에 있다. 반면 CFST는 실험적 결과에 의존하는 경향을 보이고 있으나 이는 많은 비용과 시간이 소요되는 단점이 있으므로 강재의 고온특성을 적용한 해석적 결과와의 상관성은 매우 중요한 의미가 있다. 따라서 본 연구의 목적은 CFST 내화성능을 해석 및 실험결과를 활용하여 상호 관계를 파악하고자 한다.

The aim of the research is to analyze a feasibility of rapid evaluation method for cement fineness by the relation analysis between density measurement using hydrometer and fineness of ordinary Portland cement. Additionally, based on the commercially available cement product, relation between a series of fundamental properties of cement mortar and fineness of cement powder was analyzed. As an experimental result, the actually measured fineness value of cement powder showed a good correlation with the fineness value obtained by hydrometer while there was poor correlation with the fineness value on specification. Especially, the density measurement in three minutes showed the closest relation with cement powder fineness, thus rapid quality evaluation of cement powder can be possible by using the regression equation obtained from the three minutes density measurement. Additionally, there was a high relation between cement powder fineness with a fundamental properties of the cement mortar such as fluidity, air content, setting time, and strength development.

Public environment including urban circumstances has taken on importance in that it could be nation's cultural powers latent these days. Also, today's study on the field of environment design so far has mainly focused on the fields of architecture and urban panning, while its consideration as the complex of various cultural factors is not enough yet. In addition, because study on the urban super graphic which greatly servos as communication between people and environment is not enough, super graphic has not arose enough public response in reality. The purpose of this thesis is to make super graphic revitalize as the meads of communication from the viewpoint of art, information arid aesthetics by looking into relationship between super graphic and contemporary art motivated in developing process. And This thesis is made studied relationship between super graphic and contemporary art divided into modernism art and post-modernism art.

Environmental sculpture is not just a decoration for architecture. It is a work of art with public interest and one of the best ways to improve street landscape design. Place of installation is very important for environmental sculpture, because it has close relationship with its surroundings and regional context. Field survey was performed on Teheran-Street, between Samsung station and Yeoksam station, central business district of Kang-Nam where lots of major buildings are located. All the 28 environmental sculptures facing Teheran-Street were examined. Relationship between environmental sculpture and street landscape design was investigated by three different points of view, relationship with architecture, intimacy with pedestrian, and space defined by the environmental sculpture. Environmental sculpture needs its own space and appropriate place to have beneficial influence on the sense of place. Environmental sculpture is important factor to control the quality of street landscape design. We should have macroscopic approach to determine place of installation, method and material of Environmental sculpture.

This study investigates the effectiveness of Jeju's public Wi-Fi policy for which the key factors of public Wi-Fi use and location characteristics are analyzed. Spatial regression analysis was conducted within a 100 m radius of public Wi-Fi access points. In the analysis, the dependent variable was public Wi-Fi usage time while independent variables included demographic factors, location factors, and other factors. The findings reveal that demographic factors such as the number of residents, the number of workers, and the number of visitors had a close correlation with the use of public Wi-Fi. In addition, the number of bus stops and land prices of each parcel, land use mix, and AP installation period had a positive correlation with the use of public Wi-Fi. On the contrary, the number of buildings by use, the total floor area of buildings, and the number of tourist attractions had negative correlations with public Wi-Fi usage time. These findings provide policy implications that more active publicity on Jeju's public Wi-Fi is needed and the convenience for access needs to be improved.

Exposure to the natural environment can cause damage to domestic wooden cultural assets, such as temples. Deterioration is accelerated by biological damage and various environmental factors. In this study, meteorological factors were monitored by equipment installed at Beopjusa temple of Boeun province and Seonamsa temple of Suncheon province. A statistical model was applied to these data to predict the meteorological factors and to compare the predictive performance of each meteorological factor. The resulting correlation coefficient between air and dew point temperatures was highest, at 0.95, while the correlation coefficient for relative humidity had a moderate value(0.65) at both the Beopjusa and Seonamsa temples. Thus, a general linear model was found to be suitable for predicting air and dew point temperatures. An analysis of correlation between meteorological factors showed that there was strong positive correlation between air temperature and dew point temperature, and between solar radiation and evaporation at both sites. There was a weak positive correlation between air temperature and evaporation at Beopjusa temple. Wind speed was negatively correlated with both air temperature and relative humidity at Seonamsa temple. The wind speed at this location is higher than average in winter and lower than average in summer, and it was hypothesized that the low wind speed plays a role in reducing water evaporation in summer, when both air temperature and relative humidity are high. As a result, damage to the wooden buildings of Seonamsa temple is accelerated.
