The results indicated that the impact could be separated into six aspects, each with their own coping behaviors. These were as follows:(1) uncertainty over gender identification: seeking and reconfirming a recognition of identity;(2) fear of losing their appearance and attractiveness: seeking medical assistance and developing a personal health plan;(3) anxiety about their role as a sexual partner: searching and collecting relevant information;(4) humiliation and an expectation of discrimination within society: intentionally hiding their illness;(5) a loss of self-esteem: reestablishing their role in the family and gaining confidence from employment;(6) a fear of change in the marital relationship: giving positive support to their spouse, while preparing for and accepting possible changes to their marital relationship.

研究结果显示冲击的产生包括六个部份，而冲击反映出的因应行为，对应如下：(1)对於性别定位的动摇：从试探中寻求与再确认重要他人的认同；(2)面临失去外貌吸引力的威胁：寻求医疗的辅助、建立一套自我养身法、另造身体之优势；(3)担心术后无法胜任性伴侣角色之职：主动的寻求与收集相关资讯、澄清疑问；(4)本身的耻感情绪，预期社会的异样眼光：刻意隐瞒疾病；(5)自我价值的贬抑：建立自己於家庭中功能性的位置、发挥所长致力於工作，从中获得成就与自信；(6)害怕婚姻关系的改变：建立对配偶的正向评价、无奈的默许与接受未来婚姻关系的可能改变、准备自己。

But at present the forests that can be cut down are fewer, so that the forestry industries are very difficult, and the situation has been very hard for the economic activities for the people there and the sustainable development of the city. Under such background, this paper does research on the problem of the sustainable development in the forestry resource-based city, find the relationship between the cut of the forest and economic development, and the problems in the economic develop process and the reasons of the declining. Then I construct the dynamic model of the sustainable development in economic in Yichun, in order to find the reciprocities among the population, resource and economics to provide more scientific data to the deciders. From the model, we can get the sustainable mode in the forestry resource-based cities.

The second part is the second chapter of the paper, is introduces efficiency measurement methods and theory on banking, make matting for efficiency of the Rural Credit Unions. The third part is the third and fourth chapter of the paper ,and it is main body of the study .The third chapter is the efficiency analysis of the object ,the result show that the efficiency of RCU correspond, some lowlihead at all times, and scale inefficacy is mostly cause of RCU integrate technique inefficacy; The fourth chapter base the result analysis the factor affect RUCs technical efficiency ,discuss their relationship.

第三部分即是论文的第三、四章，这也是本研究的主体部分，第三章是对研究对象的DEA效率分析，首先对模型和指标的选择做出了详细的解释，并通过D卧模型实证分析了2000-2005年研究对象的效率及变化情况，结果显示苏北地区的农村信用社效率水平相当，部分县区的农信社效率在几年中一直低下，并且规模无效是导致农信社综合技术无效的主要原因；第四章主要用了经济计量学方法分析了影响农信社效率的主要因素与农信社效率的关系，得出资产规模、经营管理费用的增加会导致农信社效率的降低，而资源配置能力、多元化经营的水平、资产质量、资本充足率以及盈利能力与农信社效率呈正相关的关系。
