基于ICAM模型的文化产业化发展路径研究

文化产业化发展缓慢有内外两方面原因:外因是文化受重视程度不够、社会效应被低估,内因则是文化的发展性弱、协调性差。针对这些问题,研究将丹尼森组织文化模型扩展为ICAM模型,从参与性(involvement)、一致性(consistency)、适应性(adaptability)与使命(mission)四个维度进行了文化产业化发展路径探讨。在此基础上,选取了武鸣三月三歌圩节作为实证研究的案例,探讨了其在ICAM模型指导下的发展对策。

基于S-CIELAB和iCAM模型的图像颜色质量评价方法的实验研究

S-CIELAB模型和iCAM模型都通过计算失真图像与原图像之间的色差对图像质量进行评价。S-CIELAB模型的空间滤波补偿了人眼视觉系统的空间混合效果。iCAM模型除了考虑空间混合效果之外,还考虑了色适应等色貌现象对图像质量评价的影响。基于视觉评价实验,选择了3幅颜色内容对比比较鲜明的图像,研究了两种模型对图像质量评价结果的有效性及准确性。研究表明,iCAM模型色差计算结果比S-CIELAB模型更符合人眼视觉实验结果。

EXPRESSION OF ICAM-1 AND LFA-1 MOLECULES IN RELATION TO RENAL ALLOGRAFT REJECTION IN RATS

Objective.The purpose of this study was to assess the renal graft expression of ICAM 1(intercellular adhesion molecule 1) and LFA 1(lymphocyte function associated antigen 1)molecule with relation to graft rejection. Methods.Rat kidney transplantation was performed according to the procedure of Kamada with some modification.Experimental rats were divided into 5 groups.The survival time of recipient rats and function of grafts after renal transplantation were observed.The sections of renal graft were stained for monoclonal antibody ICAM 1 and LFA 1, and then quantification of ICAM 1 and LFA 1 expression was accomplished by computer image analysis. Results.ICAM 1 and LFA 1 increased significantly in the renal allograft rejection group as compared with the non rejection groups(P<0 05). Conclusion.Both biopsy of renal graft and monitoring of ICAM 1 and LFA 1 are useful tools in diagnosing and treating acute rejection.
