본 연구에서는 ITO/PEDOT:PSS//PFO:MEH-PPV/LiF/Al 구조를 갖는 고분자 유기발광다이오드를 제작하여 발광 도펀트인 MEH-PPV의 농도에 따른 황색 PLED 소자의 전기·광학적 특성에 대하여 조사하였다. MEH-PPV의 농도를 각각 6, 7, 8, 9, 10 wt% 로 변화시켜 소자를 평가한 결과 9 wt%의 농도에서 가장 우수한 전기 및 광학적 특성을 보였으며, 16 V의 인가전압에서 약 630 cd/m2의 휘도 특성과 256 mA/cm2의 전류밀도 특성이 관찰되었다. 또한 10 wt%의 소자에서는 오히려 낮은 광학적 특성이 관찰되어 9 wt%에서 도펀트의 농도가 포화됨이 관찰되었고, 제작된 소자의 색좌표 (CIE coordiante)는 모든 소자에서 (x ,y = 0,49, 0.49)로 거의 동일하게 나타났다.

In this research, we survey the effects of martial art to character formation of university students statistically, and to collect data supporting them we ask questions to two groups of students who major in police administration in nation: one group have 350 holders of a rank in judo and fencing and the other have 100 students with no rank. For data analysis, mean and standard deviation of students are used, and T-test also analyzed for statistical significance test. The results are as follows: First, we study the effects of judo training with two group of students, more than one ranked group and no ranked group. In the case of rank one, male students with rank have more all the factors than students with no rank Female ranked students have more Dominance, Impulsiveness, and Maculinity than no ranked students. In contrast, no ranked students have more General activity, Reflectiveness, and Sociability then ranked students. In the case of rank two, male students with rank also have more all the factors than students with no rank. Female ranked students have more all the factor but impulsiveness than students with no rank. Second, we study the effects of Fencing training with two group of students, more than one ranked group and no ranked group. In the case of rank one, male students with rank have more General activity, Dominance, Reflectiveness and Sociality than students with no rank, and students with no rank more Impulsiveness and Masculinity. Female ranked students have more General activity, Maculinity and Sociality than others. Third, in comparison between students with rank in judo, more than one ranked male students have more all the factors but Masculinity than one ranked students. And more than one ranked Female students have more all the factors but impulsiveness. In the case of fencing, more than two ranked students have more all the factor but Reflectiveness than students with no rank.
