웹사이트의 평가작업은 결코 쉽지 않은 작업이다. 실무 전문가를 중심으로 많은 사람들이 웹사이트 평가모형에 대한 논의를 지속하고 있으나, 아직 개념체계 조차 검증되지 못하고 있는 실정이다. 이러한 상황 속에서 이 글은 웹사이트 평가모형을 탐색하기 위한 예비과정으로서 웹사이트 평가에 대한 선행연구의 검토를 통하여 평가모형 구축을 위한 주요 개념들을 적출하고, 그러한 개념들을 중심으로 탐색할 수 있는 평가과정의 단계들을 제시하고자 하였다.
Hybrid flexible transparent electrodes and its applications
김도근 한국공업화학회 2015 한국공업화학회 연구논문 초록집 Vol.2015 No.1
Recently, printed electronics based on solution process are paid attentions because of great potentials which can be simply processed, realized low cost process and applied to roll-to-roll system. Indium-tin-oxide (ITO) is most widely used materials for transparent conductive electrode (TCE) in opto-electronic devices. However ITO films are made by vacuum process such as sputter, furthermore the brittleness of ITO films is a bottleneck for flexible electronics. Poly(3,4-ethylenedioxythiophene) poly(styrenesulfonate) (PEDOT:PSS), reduced graphene oxide and silver nanowires (AgNWs) are strong candidates for substitution of vacuum deposited TCEs. The limited sheet resistance, however, gives high electrical losses of cells and leads to decrease efficiency. To solve these problems, we have developed a hybrid structure of soluble TCEs which consist of very narrow printed Ag grids for assisted electrodes which were embedded in flexible substrate. After then we have prepared the bottom electrodes such as AgNWs, Graphene, ITO, and others on the top of Ag grids. Organic devices such as OLEDs and OPVs were prepared using these metal embedded flexible TCEs substrate. These OLEDs and OPVs showed very higher flexibility which could withstand after almost folding, 1 mm of bending radius and show similar efficiencies compared with that of ITO.

Objective: We applied chest radiographs to scoliosis screening for conscription. Prevalence, types of scoliosis, and insight of examinees with scoliosis were investigated. Methods: In this study, chest radiographs of 2417 males, who had been given an examination for conscription at the Seoul Regional Military Manpower Administration from April 2009 to May 2009, were analyzed. The prevalence of scoliosis more than a 10 degrees Cobb angle was calculated. The insight of scoliosis was investigated in every examinee and thoracolumbar radiographs were checked in those examinees with more than a 20 degree Cobb angle. Results: Among 1904 males, 477 (19.7%) exhibited scoliosis involving more than a 5 degrees Cobb angle were and 131(5.4%) exhibitedmore than a 10 degree Cobb angle. In those 131 cases, 18 (13.7%) had a known history of problems with scoliosis. Among the group measuring less than a 10 degree Cobb angle, 1.7% of them misunderstood scoliosis. Insight of scoliosis increased according to the severity of spinal curvature; however, nearly half of the cases with a 20 degree or greater Cobb angle had no insight with respect to their scoliosis. Conclusion: In male adolescents, the prevalence of scoliosis with a greater than 10 degree Cobb angle was 5.4% and there was a low insight with respect to scoliosis.

공동체미술 호감도가 프로젝트 성과와 공동체의식 및 내적 정치효능감에 미치는 효과
김도근 한국콘텐츠학회 2023 한국콘텐츠학회논문지 Vol.23 No.8
본 연구는 공동체미술 프로젝트의 효과성 경로를 통계적으로 실증하고자 하였다. 연구대상은 부산지역에서 공동체미술의 프로젝트 수행경험이 있는 마을주민으로 하였다. 연구내용은 먼저, 공동체미술의 호감도가 프로젝트 성과에 미치는 영향을 검정해 보는 것이다. 다음은 프로젝트의 성과가 공동체의식에 유의한 영향을 미치는지를 분석해 보는 것이다. 마지막은 공동체의식이 정치효능감에 유의적인 영향을 미치고 있는지 확인해 보는 것이다. 연구결과를 요약하면, 먼저 공동체미술 호감도는 공동체미술 프로젝트의 사회문화적 성과와 경제적 성과 그리고 거주환경 성과에 긍정적 영향을 미쳤다. 두 번째, 프로젝트 성과 중에서는 사회문화적 성과만이 공동체의식에 긍정적 영향을 미쳤고, 경제적 성과와 거주환경 성과가 공동체의식에 미치는 영향을 통계적으로 유의하지 못하였다는 점이다. 세 번째, 공동체미술 호감도는 공동체의식에 긍정적 영향을 미쳤고, 공동체의식은 내적 정치효능감에 긍정적 영향을 미쳤다는 점이다.
