In the paper only the range of normal value and the description of frequency distribution are discussed. In theory the widely-used percentile method to determine the range of normal value is imperfected. Curve fitting method show some advantage in determining the range of normal value, but is difficult to calculate.

从理论上说明了现在常用的确定正常值范围的方法存在一定的问题，尤其证明了大家使用得比较多的百分位数法存在的缺陷，说明了曲线拟合法的优点，而在频数分布拟合完成之后，就已经找到了频数分布资料的理论分布曲线，有了理论分布函数，我们利用分布函数计算正常值范围就比较容易，也比较准确。

Secondly, there are bigger value at risk by Historical Simulation Method of risk-factors free, represented investitive net value are NT 10,000,000, maximum loss of 5﹪probability will greater than NT 2,816,827 or NT 2,344,946. So used considering VAR－Bootstrap of risk factors were more appropriated model, because model of considering risk factors were able to accurate estimate reality value at risk.

二、以未考量风险因子之历史模拟法及GARCH－拔靴法所估计风险值较大，表示投资净值一千万，有5﹪的机率可能的最大损失会大於2，816，827元或2，344，946元，因此，考量风险因子之VAR模型－拔靴法为较适当之模型，因有考量影响风险之因子，较能准确估计出实际之风险值。

I. An analysis of the prominently related variables with whether or not to receive cervical smear screen of tendency factors, enabling factors and needs factors by using the logistic regression model was performed.: 6 variables of tendency factors with predictive value as to whether a woman receive cervical smear screen or not include age, marital status, educational level, family structure, religion, and the knowledge of free smear examination offered by mandatory citizen health insurance; 4 variables with enabling factors with predictive value include average monthly income, district, whether receiving telephone or letter notices in the past year, and the degree of convenience of the examination location. One variable of needs factors with predictive value: is the suitability of the examination time notified. The accuracy rate of laddered logistic regression model built by this research was 74.1%.

This dissertation generalizes the values of the Third Way and points out that the values of the Third Way takes the exceeding over the traditional left-winger and new righty as its value tropism, takes the democracy, liberty, equity, liability and internationalism as its basal value conception, takes the establishment of a lifeful government and society as its value goal. It is an open system of values that inclues the political values, economic values, social values and international values.

The mean ADC value of lymphomatous, metastatic and benign lymph nodes was (0.874±0.17)×10~(-3)mm~2/s,(0.98±0.09)×10~(-3)mm~2/s and (1.20±0.10)×10~(-3)mm~2/s. There was statistically different between benign lymph nodes and other groups (P=0.00). When an ADC value of 1.085×10~(-3)mm~2/s was used as a threshold value for differentiating malignant from benign lymph nodes, the best results were obtained with an sensitivity of 87.8% and specificity of 91.3%. 16 of 18 cases (88.9%) were accurately staged in accordance with clinical staging. For 24 patients after chemotheraphy or radiotheraphy, 4 cases were complete remission and WB-DWI was negative. WB-DWI was positive in 14 of 17 cases with recurrent or remnant tumor. For 3 patients with suspected partial remission, WB-DWI indicated necrosis in 2 cases and inactive in 1 case. Repeated WB-DWI examination was performed in 13 cases, tumors were eradicated in 6 cases, improved in 4, expanded in 2. A new colon carcinoma besides its primary lesion was found in 1 case. The results of WB-DWI were all concordant with other clinical tests.
