        국교교사의 의복색상이 아동들의 학습교과에 미치는 영향 -SD 법을 중심으로-

        김진,김길동,오병완,김명진,이진규,조암,Kim, Jin,Kim, Gil-Dong,Oh, Byung-Wan,Kim, Myung-Jin,Lee, Jin-Gyu,Cho, Am 대한인간공학회 1991 大韓人間工學會誌 Vol.10 No.1

        This study deals with a quantitative analysis of the effects of colors on learning effectiveness. First, sensuous or emotional factors that school children feel about colors of teachers' clothes are measured by SD method and analyzed by factor analysis. Second, sensuous or emotional factors to enhance learning effectiveness are measured by SD method from teachers, and principal factors are extracted by factor analysis. Finally, the analysis of interaction between the effects of colors and the learning effectiveness is done using the sensuous or emotional factors found from the previous two analyses. The results are as follows: (1) For in-class concentration, the principal factors are "stable", and "near" feelings. The colors related to these feelings are black, red, and blue. (2) For question inducing, the first principal factors are "soft" and "stable" feelings, and the colors are white and black. The second principal factors are "gentle" and "refined" feelings, and the colors are orange and black. (3) For extra-curricular activity, the principal factors are "artless" and "plain" feelings, and the color is blue.

        퍼지집합에 의한 FT 분석 및 신뢰성분석

        조암,김길동 한국산업안전학회 1997 한국안전학회지 Vol.12 No.3

        The conventional fault tree and reliability analysis gives in many cases insufficient information concerning the relative frequencies of hazard events. This stems from that the basic events are not stationary and ergodic, and therefore the tolerances of the induced and top events cannot be calculated reliably based on the classical probability theory. To overcome this difficulty, the paper considers the relative frequencies of the basic events as fuzzy numbers and uses instead of probability, possible considerations for evaluating the mean values and tolerances of the top events. The possibility distribution of the basic events can be approximated based on heuristic considerations. This paper shows the use of these operators for constructing fault trees. The use of the method for numerical calculation is demonstrated on a field safety problem.

      • 診斷放射線科의 쾌적환경을 위한 연구

        권대철,전용웅,김길동,조암 동국대학교 산업기술연구원 1999 산업기술논문집 Vol.14 No.-

        본 연구는 종합병원 진단방사선과의 환경인자 개선을 위한 쾌적환경에 관한 연구이다. 이를 위하여 진단방사선과의 주요환경이자인 소음, 조도, 색체, 온도, 습도, 총부유분진, 악취, 환기 등의 환경인자 측정이 이루어졌다. 환경인자에 대한 환자와 직원을 비교한 결과, 환자는 불만족, 직원은 대체로 만족한다고 비교되었다. 그리고 환경인자에서 낮은 수치를 보인 병원은 S병원이고, 본 병원과 C병원이 비슷하였다. This study is about the comfort environment for improving the environmental factors in diagnostic radiology of general hospital. To see, to investigate the major environmental factors of noise, illumination, color, thermal factor, humidity, TSP(Total Suspended Particulate), odor, IAQ(In Air Quality), the field measurement were conducted. The results of the comparison of patients with employees in diagnostic radiology showed that the major comfort satisfaction which have patients was dissatisfied, employees was satisfied of diagnostic radiology in environmental factors. And a comparison of environmental factors in a study hospital same as C hospital and S hospital is lower level standards.
