The purpose of this study is to find the meaning of the good class, and based on this, situation of environmental education in high school is researched. Through those above processes, desirable direction of the environment class is suggested. For this study, we are trying to reflect the characteristics of environmental education on the general good classes, and from this, the meaning of good environment class is known. Moreover, for this study, we choose environment classes from four high schools leading by environment major teacher. From those four classes, we analyzed these things: educational situation of environment class, teachers' interviews. All of these are for analyzing environment class with the view of good environmental class. A well-formed environment class manifests the features of environment education in all aspects of teaching and learning process, including learning objectives, learning materials, procedures, and evaluations. Furthermore, it should be 'student-centered' class in which active interaction among the learners or between the instructor and the students is considered most important. Students are not the passive receiver, but rather, they actively participate in the learning process by reorganizing the knowledge as they experience and become independent learners who are actively involved in the problem-solving process. In this way, we can generate a great deal of students' interest and motivation, which in turn makes the class interesting, enjoyable, full of energy and still effective. If there is the class reflecting the factors of environmental education above good class' ways, it will be the good environment class. In the current situation of environment class, the rate of student's class participation and study activity was low. This tendency is not too different between four groups except students' support to teachers. This result means that learners' will to participate in their classes actively is not high. Moreover, about 46.3% of students did not understand some parts of new knowledge and about the parts, students' solution was 'does nothing' and the rate was also so high. Teachers tried to make their class with considering students' interest, and focusing their learner's real life. However, learners are all general education high school students, so teachers have aversion about making their students heavy activities.

This paper describes a statistical analysis method for predicting a coast fishing boat's effective horsepower. The EHP estimation method for small coast fishing boats was developed, based on a statistical regression analysis of model test results in a circulating water channel. The statistical regression formula of a fishing boat's effective horsepower is determined from the regression analysis of the resistance test results for 15 actual coast fishing boats. This method was applied to the effective horsepower prediction of a G/T 4 ton class coast fishing boat. From the estimation of the effective horsepower using this regression formula and the experimental model test of the G/T 4 ton class coast fishing boat, the estimation accuracy was verified under 10 percent of the design speed. However, the effective horsepower prediction method for coast fishing boats using the regression formula will be used at the initial design and hull-form development stage.

Classes are apt to include useless codes and inadequate inheritance relationship between them when they are being updated, inserted and deleted during the evolution process of object-oriented software, leading to lots of errors. Conventional class restructuring methods degrade the effectiveness of reusability since they go with preprocesses such as dependency analysis and estimation of class cohesion and run statically. In this paper, we propose a new C＋＋ class-restructuring algorithm that does not require those preprocesses and runs dynamically by improving ART learning algorithm in the artificial neural networks.

This paper is aimed to propose the design database(DB) of the inline micro-turbine for 5kW class. CFD analysis is performed to investigate the effect of a turbine on each parameter. This study showed that RadhaKrishna's data is different from the 5kW class in the low-head and the micro-turbine. Therefore, new DB for the design of inline micro-turbine for 5kW class could be needed. This study configured new design DB for the design of inline micro-turbine for 5kW class. The DB of this study showed that the optimal hub ratio(Dp/DR), the optimal body ratio(Db/DR) and the optimal range of body length ratio(Lh/DR) is 50%, 1.1 and 2.3 to 2.9, respectively.

The technology of small and medium sized shipbuilding companies is lower relatively to major shipbuilding companies, and should be up-graded from the viewpoint of national economic development. In spite that hul form design is one of the most important elements with respect to shipbuilding technology, small and medium sized shipbuilding companies are incapable of developing hull form. Inorder to support technically such companies hull form development was carried out for G/T 999ton class tanker and D/W 4990ton class tanker which are the typical vessels operating in coastal area. The operating efficiency for the developed hull forms are impeoved by 30% for G/T 999ton class tanker and 24% for D/W 4990 tonclass tanker respectively. The results of hull form development including ship model test and performance analysis are presented in this paper.

As an activity of one working group for the Good Practice program at Kumamoto University, we proposed a questionnaire survey on the degree in which students understand the uppermost points of importance in their classes in addition to the usual type of class questionnaire. Each class lists three uppermost points of importance which are essential for understanding the class content. The degree of understanding is classified into four levels: full, most, insufficient, and not at all understandings. Through the analysis of questionnaire replies, the degree of understanding for bachelor students in the Department of Engineering was discovered to be meaningfully affected by the degree of difficulty, the effectiveness of audiovisual aids, self-study time, and class attendance.
