우리나라 역사의 보고(寶庫)이자 정신문화의 중심인 경북 안동시. 도산서원과 하회마을 등 유서 깊은 선비문화로 유명한 이곳에 앞으로는 '최첨단 친환경 에너지 도시'라는 수식어가 더 추가될 것으로 보인다. 안동시 풍산읍 일대에 대규모 청정에너지 발전시설인 '한국남부발전(주) 안동천연가스건설소'가 점차 제모습을 갖춰가고 있는 중이다. 이곳 현장은 첨단 친환경 신기술을 동원해 시공에 임하고 있는 것은 물론 안동의 상징물인 서의문을 본뜬 정문과 고택의 담장을 연상케하는 담에 기와를 얹는 등 건축물 전반에 안동 고유의 멋과 특성을 고스란히 담아내고 있다. 또한 에너지 파크를 조성하는 등 지역과 상생하는 체험프로그램의 개발과 마련에도 총력을 기울이고 있다. 이 모두 안동천연가스건설소의 자부심과 자랑이지만, 이곳을 더욱 빛나게 하는 것은 따로 있다. 그것은 바로 '안전'이다. 산업재해와 안전사고가 발생해 선비정신에 누를 끼치는 일이 없도록 안전관리에 총력을 기울이고 있는 것이다. 철저한 안전관리로 한국 정신문화의 수도 안동에 새로운 랜드마크를 건설하고 있는 이곳 현장을 찾아가 보았다.

It is very important to understand and analyze the interactive behaviour between ground and adjacent structures due to tunneling. With many technological advancement in modern society, numerous methods for analyzing the interactive behaviour are used in a wide range of civil engineering fields. Close range photogrammetry is mainly being used in the field of geotechnical engineering and research on measuring methods associated with GeoPIV has been currently increased. Originally, the close range photogrammetry using target points and aluminum rods for VMS (Vision Measurement System) program has been used. However, applying this has a problem that external errors can be occurred because the target points are artificially installed by hand, and if the grid between points is being wider or narrower, deficient data can be obtained. Therefore, in this study, MATLAB-based No-target program that can analyze displacement without using target was developed. Additionally, this study focused on comparison and verification with existing program through numerical analysis and laboratory model test. Three cases of Greenfield condition, Strip foundation, and Pile foundation were analyzed. From results of VMS program and No-target program, the error rate and reliability of the total displacement and the vertical displacement were analyzed. It was also compared and verified through the finite element numerical program, PLAXIS.

Most of large construction companies have developed construction information systems and their ultimate goals should be improvement of the management efficient of the construction projects. In order to make them successful, tile systems should be designed to meet system users' needs. Therefore purpose of this study Is to evaluate the current information management systems from the viewpoint of the system users, especially on-site engineers. Questionnaire surveys and interviews have been conducted for the highly ranked 10 construction companies on two major factors including the functions of the systems and satisfaction level of each function. From the surveys results, correlation between two factors has been statistically analyzed.

The construction market has a major impact on the overall United States economy. Recent statistics estimate the gross domestic product (GDP) of the U.S. construction industry at some $416.4{\$}$ billion dollars, representing approximately $4.5\%$ of the U.S. GDP. Because the business environment in construction is highly competitive, the participants in the industry must improve their performance and processes to survive. Hence, Benchmarking has been generating interest in the construction industry. This paper provides an overview of the CII Benchmarking and Metrics Program. Following some background and a descriptive discussion of the database, an abridged presentation of result of data analysis. The adoption of benchmarking in Korean construction industry can be another opportunity to improve Korean construction industry.

본 연구에서는 낙동강수계 도시의 주요 용수공급원인 댐유역의 연강수량과 연유입량자료를 수집 후 "NDIC-FAT" 가뭄빈도해석 프로그램(한국수자원공사 국가가뭄정보분석센터(NDIC), 2020)을 활용한 가뭄빈도분석을 시행하여 과거 동일기간과 비교하여 현재의 강수량 또는 유입량의 재현기간 및 크기를 산정하고, 수집된 연구대상 유역의 연강수량과 연유입량자료에 대한 상관식을 개발하여 가뭄빈도에 따른 연유입량 값을 가뭄빈도해석프로그램의 분석결과와 비교하여 본 연구에서 제안된 상관식의 활용성을 검토하였다. 가뭄빈도분석 결과 강수량에 따른 확률분포형은 6개의 유역중 2개소(남강댐, 합천댐)에서 AIC값에서 Normal 분포형이 가장 낮았고 나머지 4개소(안동댐, 영천댐, 운문댐, 임하댐) 유역은 AIC값에서 Gumbel 분포형이 가장 낮게 나타나 본 연구에 적용하였다. 연유입량에 따른 확률분포형 검정은 남강댐, 안동댐, 영천댐, 운문댐, 임하댐, 합천댐 유역 6개소 모두 AIC값에서 2변수 Log-Normal 분포형이 가장 적합한 것으로 평가되었다. 연구대상 유역의 연강수량과 연유입량자료를 이용하여 연유입량에 대한 상관식을 개발하여 비교한 결과 영천댐유역을 제외한 5개 유역의 일치율이 높게 나타났다.

Korean government is carrying out educational training program for the competencies of the construction engineers. However, this training program is insufficient to take advantage of the practice. Therefore, the purpose of this study is to investigate and analyze the satisfaction and problems of educational programs at training graduates. And we have suggested the improvement directions of educational program. The results of this study, satisfaction of training programs for construction engineers generally was investigated highly. However, this has been underestimated in terms of capacity-building abroad. And there are operational problems including lack of educational programs using in construction site, lack of training program courses in few work sector and lack of graded training program. Therefore, we have proposed the development direction of training program for construction engineers to solve this problem.

전력설비에서 발생하는 전자계는 지역 주민들의 가장 큰 민원 제기 대상 중의 하나가 되고 있다. 이로 인해 신설선로의 경우 선로 건설을 반대하거나 선로를 다른 곳으로 이설 요청하는 등 건설 공사가 지연되어 원활한 전력 사업에 많은 지장을 초래하고 있는 실정이다. 이와 같은 현상을 예방하기 위해서는 지역 주민들에게 전자계에 대한 홍보를 통해 이에 대한 정확한 이해를 심어주는 것이 절실하다. 이를 위해서 송전선로에서 발생 가능한 전자계의 크기를 예측할 수 있는 프로그램을 이용하여 정확한 Data를 제시함으로서 주민홍보에 큰 성과를 얻을 수 있을 것으로 믿어진다

Presently, working gas pipelines are being subjected to the influence of construction vibration. Especially on subway and road construction, gas pipelines are being influenced to construction vibration caused by use of construction equipment, passage of a large-sized vehicle and blasting. Buried gas pipelines are subjected to the influence of vibration caused by blast in the vicinity of pipeline, exposed gas pipelines are subjected to the influence of vehicle vibration. Therefore, in the study, it is developed to vibration prediction program of gas pipeline by analyzing measured construction vibration. This program is able to predict vibration of gas pipeline according to field conditions by using the results of structural finite element analysis and empirical equation by reliability analysis. And, this program contains the database of construction vibration. Additionally, this program is able to compute estimated blast vibration equation using measured blast vibration data in the field and to form graph of allowable charging gunpowder per delayed-action with the change of blast velocity. Therefore, field workers are able to predict construction vibration around gas pipeline and estimate safety of gas pipeline.
