The engineering education through making robots which needs various techniques such as construction of mechanism and electric circuit design are very useful for training of the students' creativity and developing the students' personality. Department of Electrical and Electronic Engineering had participated in RoboCup world competition since 2004 as a part of engineering education and been getting spectacular results.This paper discusses the effect continuous participation in RoboCup world competition on the engineering education including students' ability of English communication, based on questionnaires to students. The results show that to participating in RoboCup world competition does not only enhance students' technical knowledge and experience,but also motivate them to learn English.

The cavity zone along riverside is expected to produce native habitats of various ecosystems and water-friendly environment. However, effects of side cavities on flow resistance and turbulent flow structures are ambiguous, because the side cavity generates the complex separated vortices. In this paper, the flow resistance and turbulent flow structure in open channel flow with lomgitudinally continuous side cavities were examined experimentally. The flow velocity was measured by using a two-component electromagnetic current-meter. Results showed that the flow resistance significantly depended on aspect ratio of side cavity and the reason could be explained by the difference of momentum transport through the interface between the side cavity and main flow region.

A stiffening Method of existing cylindrical steel piers is studied by experimental ways. On the experimental way steel piers are stiffened by longitudinal steel plates on it. On the Stiffening structures are set using the plates and local buckling points created forcibly on the pier. The part of the pier which yields local buckling is controlled in base zone of it by this Stiffening structures and the ductility of the piers are improved with small increase the ultimate strength of it. We have been able to improve the ductility of piers by the Stiffening structure.

Integrated meteorological observation device was newly established by Toyota National College of Technology in 1996. And, 24 hour of weather element continuous measurement became possible. This report is a report when annual to the observation from January, 1997 to December, 2009. The observation results were compared with an existing research result by the value of the common year of Toyota City.

3次元表現された都市的空間の画像を我々がどのように認知・理解し、何を手掛かりとし、それをどの程度正確に構成することができるのかを分析した。また、学習経験の違いによる理解・把握の傾向について探った。1)3次元の都市的空間を正確に理解・把握することは容易ではない。学習経験の浅い被験者(中学生)は特に奥行き感覚を把握しづらいことが示唆された。また、対象が拡大・複雑化するにつれ細部の把握が困難となることが推察された。2)図面を参照する機会の多い建築学を専攻する学生は、現実の空間と照合しながら空間模型を制作していく傾向があった。これに対し、中学生は図面のみを参照し、それを忠実に表現していくことに没頭していたと推察できた。3)被験者は空間の全体構成をまず把握し、その後に部分的な情報により全体が統合されていく傾向が示唆された。但し、中学生は模型パーツを配置させる回数が多く、試行錯誤しながら模型製作を進めていったと推察できた。

The restoring force characteristic of wooden houses is slip type. The energy absorption of slip type restoring force characteristic is less than the energy absorption of normal bi-linear characteristic restoring. On the other hand, a shear wall of wooden houses is evaluated with the resisting force ratio of various wooden walls. If a shear wall which has both normal bi-linear characteristic restoring and the high resisting force ratio of various wooden walls, that wall is valuable. In this paper, we develop a wooden wall which a steel frame and a friction dumper. We adopt aluminum, zinc or polycarbonate as slide mamber. As a result, the wall that we developed has the bi-linear restoring force characteristic, and the resisting force ratio of various wooden walls is 4.0. The bearing force deterioration of this wall is 0.1-0.2kN/cycle with aluminum as slide member.

The architectural structural mechanics is the only building-up course in Department of Architecture. A structural mechanics is a good course to evaluate students' ability because of its eternalness. In this report, the ability shift of students is analyzed on architectural structural mechanics course. As a result, the correlation between the regular exam result and quiz results is weak. The correlation between the regular exam result and homework results is also weak. The ability shift of students is not changed from 2004 to 2009.

The purpose of this study was to estimate the physical active intensity in ski education form the viewpoint of heart rate responses during skiing and/or snowboard practice. We measured the heart rate (HR) of 7 practiced skiers (:PS), 5 beginner skiers (:BS), and 6 beginner snowboarders (:BB). The HR was measured with portable heart rate monitors from 08:30 am to 04:30 pm during the practice. We analyzed the HR with an exclusive software package. The mean of the HR during the practice was 120.1±9.6 beats/min (PS), was 131.0±11.2 beats/min (BS), and was 115.7±13.0 beats/min (BB), respectively. The estimated physical active intensity was 59.3±4.7%HRmax (PS), was 64.5±5.6%HRmax (BS), and was 57.0±6.4%HRmax (BB), respectively. From the present results, we have found that physical active intensity was approximately 57%〜65%HRmax during the ski and/or snowboard practice.

In this note, we analyze factors in pleasant classes of mathematics. In sections 1 and 2, we sort the factors into two groups. One of them consists of elements in classes, and the other consists of those in pleasant. In each group, we pick up main elements in classes and pleasant, respectively. In section 3, we introduce several examples of methods of classes enhanced by those elements, where we indicate which elements please those classes.
