Mostly I accomplish following tasks:(1)After analysis of the mobile agent platform of IBM, I find problem in safety precautions. Aglet uses unilateral secure safeguard, that is to say, which emphasize on system protecting and lose sight of the security of itself.

主要完成的工作有：(1)本文在对IBM的移动Agent平台进行深入的研究后，发现在安全性措施的处理上，Aglet实现了单向的安全性保护，也就是说，它着重强调了对于系统的保护，忽略了对于Aglet本身的保护，比如在传输过程中的保护。

It can oppose the third part in conditions. From the point of view of the value of the law, the priority of labor"s creditor"s right takes the value to protecting live value of the human being, to preserving the social equality and justice, to protecting the puny, to dispersing the social risks, to protecting the basic human rights. According to the institutional theories of law, the priority of labor"s creditor"s right has the important value that it can realize justice; optimize the allocation of the risks, encourage people to supervising the discharge of the labor"s creditor"s right. On the basis of the sociology of law, the priority of labor"s creditor"s right is the social demands development and has strong social sense.

从法的价值理念的角度看，劳动债权优先权制度秉承的保护人类的生存价值，维护社会公平正义，保护弱势群体，分散社会风险，保护基本人权，推行保护劳动者的社会政策的价值理念；从制度法学的角度看，劳动债权优先权制度具有实现公平、优化风险配置、激励社会力量对劳动债权的及时清偿进行监督和督促的重要制度价值；从法社会学的角度看，劳动债权优先权制度是社会发展的需要，具有很强的社会意义。

Evaluation of IEM103 in rabbit animal model.The evaluation was based on the control-challenge study (IEM101 as control). Rabbits were laparotomized, injecteded 10〓 cfu directly into proximal small bowel, and 28 days later, challenged with 0.25--2ug CT and 10〓-10〓 cfu 4 wild toxic strains with different biotypes and serotypes. Experimental group developed antitoxic and significant vibriocidal immune responses to vaccination, and could protect no less than 2ug CT and 10〓-10〓 cfu all wild strains challenge.

IEM103的免疫原性评价：经兔肠段结扎免疫〓cfu IEM103，7天后在外周血中可检测到外周淋巴细胞分泌性抗CT IgG，血清中可检测到抗CT抗体、杀弧菌抗体，P／N均≥2，且可持续至28天。28天后用0.25-2ug CT毒素，四种毒株滨-43，吴江-2，395，1119〓cfu菌量攻毒，实验组可保护至少2ug CT攻毒，而对照组可保护1ug以下CT攻毒，两组均可保护〓cfu四种毒株攻毒（以肠积液量≥1.0ml／cm为不保护判断标准）。
