N/A Objective : This study was performed into investigate the effects of Dianthi Semen and Benincasae Semen on the body weight, serum lipid and histochemical change of rats fed high fat diet. Method : I orally administrated the extracts of Dianthi Sernen(3OmB/lOg rat weight) and Benincasae Semen(4.5mg/100g rat weight) to the experimental group and a saline to the control group for 8 weeks with high fat diet. Result : 1. The body weight in BS group were decreased and on the 7 and 8 week statistically showed the significant difference with the control group. 2. The contents of serum total cholesterol, FFA and phospholipid in DS group were decreased and statistically showed the significant difference with the control group, 3. The contents of serum total cholesterol, FFA, phospholipid and LDL-cholesterol in BS group were decreased and statistically showed the significant difference with the control group. 4. The average size of the epididymal fat cells in DS group was decreased and statistically showed the significant difference with the control group. 5. The area % of the hepatic fat drops in Ds and BS group was decreased but didn`t show the significant difference with the control group. Conclusion : Dianthi Semen and Benincasae Semen had preventive effect on obesity of rats fed high fat diet.
A Note on Teaching Statistics in The School Class

In teaching statistics in the secondary school, most math teachers do it and students enjoy it well before 11th grade. But, both of teachers and students feel statistics hard at 11th grade, which has been contained permutations, combinations, random variables, probability distributions, hypotheses and tests for normal distribution. In this study, we explore the efficient teaching methods of statistics for math teachers and also find many students enjoying it.

In this paper, we dealt with various special features of Multimedia teaching·learning and the diverse condition of the elementary school and the secondary school. This connected with the analyses under our country's actual circumstances. We researched the facilities environment about Multimedia teaching·learning model development, and Today is the information -oriented society, and the future-oriented, and the statistical data of the teacher's opinions of national elementary school and secondary school. We raise several points about practical use of exciting learning software through analyses and present the necessity of learning model development.

Function approximation from a set of input-output pairs has numerous applications in scientific and engineering areas. Multilayer feedforward neural networks have been proposed as a good approximator of nonlinear function. The back propagation(BP) algorithm allows multilayer feedforward neural networks to learn input-output mappings from training samples. It iteratively adjusts the network parameters(weights) to minimize the sum of squared approximation errors using a gradient descent technique. However, the mapping acquired through the BP algorithm may be corrupt when errorneous training data we employed. When errorneous traning data are employed, the learned mapping can oscillate badly between data points. In this paper we propose a robust BP learning algorithm that is resistant to the errorneous data and is capable of rejecting gross errors during the approximation process, that is stable under small noise perturbation and robust against gross errors.
