The preparation of water-repellent films by plasma-coating has been reviewed and then unique applications of the hydrophobic films are also introduced. Ultra-water-repellent films with a water contact angle of 150 degree have been synthesized by capacitively couple plasma enhanced chemical vapor deposition using C₂H₂F₂ / Ar mixture gases for next generation automobile window. Scanning electron microscopy shows that the prepared films have an irregular rough microstructure in which particles of submicron diameter are complicatedly intertwined. Fourier-transform infrared spectroscopy indicates that the films include components of the C-H and C-F bonds, characterized by having a hydrophobic nature. A zirconium oxide (ZrO₂) thin film was prepared using oxygen inductively coupled plasma sputtering of the zirconium target with a negative bias for protecting china from metallic contamination. It is found that the prepared ZrO₂ films have water-repellent nature with contact angle of about 100 degree.

When a student has some questions on a class subject, he should ask questions in his class. However, the student, who cannot ask the question in the class, has to go to the teacher to ask questions after hours. In such a case, it is the problem that profitable information discussed between the teacher and the student by questioning will not spread over all students. Therefore, we have designed and implemented the system which provides smooth communication and sharing information after hours. In this paper, we describes the further improvement on enriched expressions and the usability on Web.

Aimed at manufacturing education, environmental education, and welfare support, a hand-made color comparator using waste plastic cups is proposed in this paper. Unlike conventional color comparators, the proposed comparator is realized by cascading three waste plastic cups. Therefore, teachers can perform environmental education not only by a water quality test but also by reuse of plastic wastes. Furthermore, by covering the color comparator with paper clay, students can make a color comparator without soldering. Since the appearance of the proposed comparator seems to be clay work, most of the students will not throw away the proposed comparator after a lesson is completed. The validity of circuit design is confirmed by experimental classes. The experiments show that 1. students can learn the basic of electricity, reuse, and manufacturing, 2. by covering a color comparator with paper clay, students can make the shape of the color comparator freely, and 3. even the students with color-blindness can receive environmental education such as a water quality test by using the proposed color comparator.

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.
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.

This study discusses the uncertainty in grade evaluation. Two courses in the first-grade students were chosen for evaluation. The uncertainty in the average score in the examinations was 7 points even under the same condition but taught by different lectures. In the condition where the syllabus and evaluation criteria were identical, the uncertainty caused by combined factors was found to be 15 points. Successive faculty development tends to make the score deviation converged in two different groups.
