이 연구는 학업적 지연행동 극복 프로그램을 개발하고 학생의 완벽주의 특성에 따른 프로그램의 효과 차이를 밝혔다. 즉 대학생 85명을 실험집단과 통제집단으로 나누어 실험집단을 대상으로 주 1회 1시간씩 총 11차시의 학업적 지연행동 프로그램을 실시하여 다음의 결과를 도출하였다. 첫째, 자기-지향적 완벽주의가 낮은 학생들에게 프로그램의 즉각적인 효과는 유의미하였으나, 자기-지향적 완벽주의가 높은 학생들에게 프로그램의 효과는 유의미하지 않았다. 둘째, 사회적으로 부과된 완벽주의가 높은 학생들에게 프로그램의...

were studied using thermal analyses such as DSC and TGA. The melting and heating enthalpy of the fibers decreased as the cross-linking temperature increased. The cross-linked fibers had a carbonization yield of over 50%. From SEM results the highest yield of carbonized LDPE-based fibers was obtained by cross-linking at a sulfate temperature (170oC). As a result, carbonation yield of the carbonized fibers was found to depend on the functions of the cross-linking ratio of the LDPE precursors.

A series of high capacity soft carbons with different phosphorus contents were successfully prepared by carbonizing petroleum cokes treated with hypophosphorous acid at 900°C. The effect of phosphorus content on the electrochemical performance of the soft carbons was extensively investigated. The P-doped soft carbons exhibited greatly enhanced discharge capacities and outstanding rate capabilities with increasing phosphorus content. In addition, the influence of temperature on the...

pore distribution before and after impregnation were easily confirmed by observing the microstructure. In addition, by using an X-ray diffractometer, the degrees-of-alignment (Da) were obtained for one side perpendicular to the direction of compression molding of the bulk graphite (the “top-face”), and one side parallel to the direction of compression molding (the “side-face”). The anisotropy ratio calculated from the Da-values obtained was 1.13, which indicates comparatively good isotropy.

and compression molding. The percolation threshold (Φc) of the MWCNT-PP composites was most successfully lowered using the mechanofusion process than with any other mixing method (2-5 wt%). The mechanofusion process was found to enhance formation of a percolation network structure, and to ensure a more uniform state of dispersion in the CPCs. The immiscible-polymer blends were prepared by melt mixing (internal mixer) poly(vinylidene fluoride) (PVDF, PP/PVDF, volume ratio 1:1) filled with MWCNT.
