This paper describes an application of a neural network for estimating the ground rainfall from radar echo data. A neural network system for this purpose is developed through a case study on a dam for hydro-power plant located the upper district of the Ooi River in Central Japan. We use the neural network comprised of three layers; an input layer, a hidden layer and output layer. The input data to the neural network are any numebr of radar echo amount observed in each radar mesh and x-y-z coordinates showing its location.<br> The four types of neural networks with different number of input units are proposed and discussed the relative importance of the number of input data. It is found that the estimating system using the most simple neural network yields good results for rainfall distribution.

Recently the importance of Monozukuri (manufacturing) has been watched with keen interest as a social; problem, which has a relation with schoolchildren's decline of their academic standards, pointed out by the reports of PISA of OECD and TIMSS, etc., and their "losing interest in science" and "dislike of science", some people worry about, which will lead to the decline of technology in the home industry, the top-class personnel shortage, and the decrease of economical power in this country in the future. In order to solve such a problem, science pavilions, universities, and academic societies of science and engineering etc. in various places hold "Monozukuiri Classrooms" or "Science Classrooms". We can say that various activities which try to hold off "losing interest in science" and "dislike of science." in the whole society. Under such a situation, Aichi Institute of Technology (AIT) to which we belong, also tries to contribute to the activity of solving the problem, and holds various engineering education lectures which intend for elementary, junior high school and senior high school students. AIT has held "The Whole Experience World" which tries to bring up a talented person who has a dream and hope towards science and technology, grows his/her originality, intellectual curiosity and spirit of inquiry, and supports the nation based on science and technology in the summer vacation since 2001.<br>This paper reports the result of a questionnaire about what kind of the long-term learning effect on the children who participated in "The Whole Experience World" and "Boys and Girls Robot Lectures". As the conclusion of the study, we can say that the lectures could give the participants who were interested in science and technology more interest. And we could give them the idea of what the study of science and technology is. As a result, we could contribute to the participants' decision of the courses' selection in life.
