회원마당 - 친환경 PC농법으로 쌀 품질 올리니 소득 늘어
김상우,Kim, Sang-U 전국농업기술자협회 2009 농업기술회보 Vol.46 No.6
김상우 지회장은 한국전쟁 당시 북한 노동당사와 백마고지 전투 때 숨진 군인들의 넋을 위로하는 위령탑 등이 있는 민간인출입통제선 안에 있는 철원군 철원읍 대마2리에서 35년째 자연의 섭리에 따라 쌀농사를 짓는 친환경 농업의 선도자로 불린다.

순환 굵은 골재 흡수율에 따른 RC 보의 부착성능에 관한 실험적 연구
김상우,이현아,정창교,김길희 한국구조물진단유지관리공학회 2010 한국구조물진단유지관리공학회 논문집 Vol.14 No.3
본 연구에서는 순환 굵은 골재를 사용한 철근콘크리트 (RC) 보의 부착거동을 평가하였다. 총 4개 실험체를 제작하였으며, 실험변수는 굵은 골재의 종류(천연 및 순환골재)와 순환골재의 흡수율로 하였다. 본 실험에서는 흡수율이 3%와 6%인 순환 굵은 골재를 사용하였으며, 실험체는 단순지지 형태로 집중하중을 받도록 계획하였다. 실험체의 부착특성을 효과적으로 평가하기 위하여 Ichinose가 제안한 실험방법을 채택하였다. 본 실험결과, 순환 굵은 골재의 흡수율에 따른 부착 특성의 차이는 발견되지 않았다. This study evaluates the bond behavior of reinforced concrete (RC) beams using recycled coarse aggregates. A total of four specimens were cast and tested. The test parameter was the type of coarse aggregates, that is, natural and recycled coarse aggregates, and the absorption ratio of recycled coarse aggregate. The recycled coarse aggregates with absorption ratios of 3% and 6% were used in this test. The specimens were simply supported and were subjected to a concentrated load. A test method proposed by Ichinose was adopted to estimate effectively the bond properties of specimens. From the experimental results, it was found that there was no difference of bond characteristics according to the absorption ratio of recycled coarse aggregates.

최근의 집값 상승이유는 시세를 마치 수능시험성적표처럼 경쟁적으로 보도하는데 있다. 한국 언론 특유의 냄비근성은 보도를 '세게 더 세게' 서로 경쟁 하게 만들어 오히려 문제가 증폭되는 악순환을 갖게 한다.

상품가치, 서비스품질, 쇼핑몰이미지가고객만족 및 애호도에 미치는 영향
김상우,박명호 대한경영학회 2004 大韓經營學會誌 Vol.17 No.3
The purpose of this study is to investigate critical factors affecting customer satisfaction and customer loyalty on the internet shopping mall. Critical factors affecting customer satisfaction and customer loyalty of the internet shopping mall suggested in this study are product value, service quality and shopping mall image. As moderating factor of the relationship between customer satisfaction and customer loyalty, switching barrier is suggested. Data are collected from 716 Internet shoppers by internet panel survey. This study analyzes the research model and hypotheses using structural equation model(SEM) and regression. The results are as follows: (1) customer satisfaction has been affected by product value, service quality and shopping mall image, (2) customer loyalty has been affected by customer satisfaction, and (3) the effect of customer satisfaction on customer loyalty has not been moderated by switching barrier. This results confirmed that customer satisfaction is strong antecedent of customer loyalty. Also, perceived product value is more important factor to influence the customer satisfaction among suggested ones. Finally, this study suggests several implications for improving customer satisfaction and customer loyalty in the internet shopping mall.

This study focuses on the improvement of construction safety based on information technology which can support perception. Theobjective of this study is to comprehensively identify the IT application areas for perception enhancement to improve constructionsafety based on the investigation of tasks for construction safety from the viewpoint of human factors regarding perception. Thecomprehensive identification reveals that 6 out of the 23 classified danger elements may potentially benefit from perceptionenhancement on the improvement of construction safety. The comprehensive identification rationalizes the areas for perceptionenhancement that should have a higher likelihood of success in their application to improve construction safety.

나노 화합물을 이용한 Acidovorax citrulli 및 식물병원성 미생물의 항균활성 효과 검정
김상우,마헤시 아드히카리,딜라지 야댜브,이현구,엄용현,김현승,이윤수 한국식물병리학회 2015 식물병연구 Vol.21 No.1
Antimicrobial activities of nano-materials were tested against several plant pathogens. Twelve different nanomaterialswere used to observe the antagonistic activity against three kinds of mold and sixteen differentkinds of watermelon fruit rot pathogens (Acidovorax citrulli). According to the results, no antagonism havebeen found against the pathogen, Cylindrocarpon destructans. However in the case of Pythium ultimum, combinationof Brass/Glucose 1,000 ppm confirmed the mycelial growth reduction by 94%. In addition, little effectwas found against Rhizoctonia solani by Ag/Glucose 3,000 ppm. The remaining other nano-materials havedifferent antimicrobial effect depending on the strains of A. citrulli. But in the case of lime (Cu/Salt 1,000 ppm)highest antimicrobial activity was observed with 97%. Moreover growth of five different strains of A. citrulliwas checked by 99% with the combination of Ag/Glucose 1,000 ppm. 92% reduction of A. citrulli growth wasobserved with Brass/CaCO3 3,000 ppm. Tested nano-materials against different plant pathogens in this studyshowed the antimicrobial activity at the range of 24-70%. 나노 화합물을 이용하여 식물병원성 미생물의 항균활성을검정하기 위하여 실험을 수행하였다. 12가지 나노 화합물을 이용하였으며, 곰팡이 3종과 수박과실썩음병(BFB: Acidovorax citrulli) 16계통을 이용하여 실험한 결과, 곰팡이 병원균에 대하여 C. destructans의 경우 항균효과가 없는 것으로 확인되었으며, P. ultimum의 경우 Brass/Glucose 1,000 ppm에서 94%의균사 생장 억제 효과를 확인하였으며, R. solani는 Ag/Glucose 3,000 ppm에서 약간의 효과는 있었으나 매우 경미한 것을 확인하였으며, 나머지 나노 화합물에서는 항균 효과가 없는 것으로 확인 되었다. A. citrulli의 경우 석회에서 가장 높은 항균 활성을 확인하였으며, Cu/Salt 1,000 ppm는 7종에 대하여 최소 97% 의 항균 활성을 보였으며, 5종에 대하여 99%의 높은 항균활성을 확인하였다. Ag/Glucose 1,000 ppm은 7종의 수박과실썩음병(BFB) 병원균 A. citrulli에 대하여 63%의 항균활성을 보여주었다. Brass/CaCO3 3,000 ppm은 석회 보다는 조금 낮은 92%의 항균 활성을 보여 주었으며, 나머지 나노 화합물은 24-70%의 항균활성을 확인하였다.
