        The purpose of this research was to investigate the moderating effect of positive and negative emotions, and the relationships among college student’s irrational belief, positive and negative emotion on their college adaptation. Tests with measures of irrational belief, positive and negative emotions, and college adaptation were carried out with a total of 408 male and female students attending universities located in Daegu City. The data collected was analyzed using correlation analysis, multiple regression analysis, and hierarchical multiple regression analysis. The results were as follows. First, it showed significantly negative correlations among the irrational belief, negative emotions and college adaption and the positive emotions represents significant positive correlations to college adaption. Second, it was found that positive emotions mitigated as a moderating variable that effect on the negative relations of college student’s irrational belief with college adaption. Third, negative emotions had not affected the college student’s irrational belief with college adaption as a moderating variables. Implications were discussed. 본 연구의 목적은 대학생의 비합리적인 신념, 긍정 및 부정 정서와 학교생활적응과의 관계에서 긍정 정서 및 부정 정서의 조절효과가 있는지를 알아보는 것이다. 이를 위해 대구시에 소재하고 있는 대학교에 재학 중인 408명의 남녀 대학생을 대상으로 비합리적 신념 척도, 긍정·부정 척도, 대학생활 적응 척도를 각각 실시하였다. 수집된 자료는 상관분석, 중다 회귀분석, 위계적 회귀분석을 실시하였으며, 검증한 결과는 다음과 같다. 첫째, 비합리적 신념, 부정정서, 학교생활적응은 유의한 부적상관을 보였고, 긍정 정서는 학교생활적응에 유의한 정적상관을 나타냈다. 둘째, 긍정 정서는 대학생의 비합리적 신념이 학교생활적응에 미치는 부정적인 영향을 완화시켜주는 조절변수로 검증되었다. 셋째, 부정 정서는 대학 생의 비합리적 신념이 학교생활적응에 조절변수로 유의미한 영향을 미치지 않았다. 연구결 과를 토대로 대학생의 학교부적응 예방 및 상담 개입활동에 관한 시사점에 관하여 논의 하였다

        키틴에 의한 중금속 Cd(II), Pb(II)이온의 흡착 및 회수에 관한 연구

        김은경,조영구,권영두,박미아,김한수,박광하,Kim, Eun-Kyung,Cho, Young-Koo,Kwon, Young-Du,Park, Mi-A,Kim, Han-Soo,Park, Kwang-Ha 한국분석과학회 2002 분석과학 Vol.15 No.2

        수산가공 폐기물로 버려지는 게 껍질로부터 chitin을 추출하여 중금속 흡착제로 이용하였으며, 이 흡착제에 대해 Cd(II) 및 Pb(II) 이온의 흡착특성을 연구하였다. Chitin에 대한 Cd(II) 및 Pb(II) 이온의 흡착속도는 반응시간 2분경에 최대흡착량에 도달하였으며, 중금속 흡착에 미치는 pH의 영향은 두 이온 모두 pH 7.0>10.5>3.5순임을 알 수 있었다. Chitin에 대한 흡착률은 Cd(II)이온이 21${\sim}$99%이며, Pb(II)이온이 24${\sim}$95%이다. Cd(II)이온의 회수율은 22${\sim}$53%이고, Pb(II)이온의 회수율은 22${\sim}$73%로 나타났다. 이들 중금속 이온의 흡착양상은 Freundlich 흡착등온식에 비교적 잘 적용되었다. The adsorption characteristics of Cd(II) and Pb(II) ions has been studied by using chitin as an adsorbent. The pure chitin was obtained from the extraction of red-crab shell dumped by fish factory. Adsorption kinetics of Cd(II) and Pb(II) ions on the chitin reached at the maximum adsorption within two minutes. Adsorbed amounts of heavy metals were pH 7.0>10.5>3.5 in the following order. Adsorption ratio by chitin was 21${\sim}$99% for Cd(II) ion and 24${\sim}$95% for Pb(II) ion. Recovery ratio of Cd(II) ion on the chitin was 22${\sim}$53%, and that of Pb(II) ion was 22${\sim}$73%. The adsorption behavior of these heavy metals was explained well by Freundlich adsorption isotherm.

        Zn_χFe_(3-χ)O_4(0.003<X<0.08) was synthesized by air oxidation method for the decomposition of carbon dioxide. We investigated the characteristics of catalyst, the form of methane by gas chromatograph after decomposition of carbon dioxide and kinetic parameter. Zn_χFe_(3-χ)O_4(0.003<X<0.08) was spinel type structure. The surface areas of catalysts(Zn_χFe_(3-χ)O_4(0.003<X<0.08)) were 15~27 ㎡/g. The shape of Zn_0.003Fe_2.997O_4 was sphere. The optimum temperature for the decomposition of carbon dioxide into carbon was 350℃. Zn_0.003Fe_2.997O_4 showed the 85% decomposition rate of carbon dioxide and the degree of reduction by hydrogen(δ) of Zn_0.003Fe_2.997O_4 was 0.32. At 350℃, the reaction rate constant and activation energy of Zn_0.003Fe_2.997O_3.68 for the decomposition of carbon dioxide into carbon were 3.10 psi^(1-α)/min and 0.98 kcal/mole respectively. After the carbon dioxide was decomposed, the carbon which was absorbed on the catalyst surface was reacted with hydrogen and it became methane.

        The spinel Fe₃O₄ powders were synthesized using 0.2 M-FeSO₄·7H₂O and 0.5 M-NaOH by oxidation in air and the spinel LiMn₂O₄ powders were synthesized at 480℃ for 12 h in air by a sol-gel method using manganese acetate and lithium hydroxide as starting materials. The synthesized LiMn₂O₄ powders were mixed at portion of 5, 10, 15 and 20 wt% of Fe₃O₄ powders using a ball-mill. The mixed catalysts were dried at room temperature for 24 hrs. The mixed catalysts were reduced by hydrogen gas at 350℃ for 2 h. The carbon dioxide decomposition rates of the mixed catalysts were 90% in all the mixed catalysts but the decomposition rate of carbon dioxide was increased with adding LiMn₂O₄ powders to Fe₃O₄ powders.
