The Japan Football Association requests that instructors who coach children (under 12-years old) give priority to the observance of rules over securing victory at all costs. On the other hand, the JFA requests all players to pursue victory as part of the JFA's fair play policy. This is a double standard. The purpose of this paper is to consider the following:firstly, criticism of the double standard about fair play by the JFA, and secondly, how to answer this question: " How can we teach fair play without contradicting ourselves?" by analyses of various interpretations of fair play. To achieve this, we will analyze some remarks concerning ethical elements of fair play. After that, we will identify any contradictions regarding these remarks.

Students of lower grades of the College of Technology is the same age as high school students. Therefore, in the business of home room teacher, there is a portion of the College of Technology and the portion that is similar to the high school. Based on my experience, I shown the failure cases and success cases of home room teacher work of the lower grades of the College of Technology. And I considered the ideal type of home room teacher work.

The purpose of this study was to investigate the new physical fitness test in this year. The subjects were 696 students (Male; 613, Female; 83) of the National Institute of Technology, OYAMA College. Subjects were new physical fitness test of eight kinds (Grip strength, Sit up, Sitting trunk flexion, Side step, 20m Shuttle running, 50m sprint, Standing long jump, Hand-ball throw).
As a result, boy student was lower than National average. But, didn't change the result of girl student. These results suggest implicate that there should be a need to increase the physical activity to improve physical fitness level.

This paper aims at presenting how different negative prefixes have been employed for producing a new word for a long time. In order to investigate the frequency of occurrence of the targeted derivatives, some corpora will be of great importance. In addition to the corpora, dictionaries will be used for the definitions of the words not only in Present-day English but also in the past.

In this study, it is an object of the present invention to develop teaching materials using the Lego Mindstorms NXT. This teaching materials, have been devised learning of mechanical engineering as enjoyable learning. We have developed a teaching material of 10 types, including the prototype. Finally, we open lecture to junior high school for, took the questionnaire for the teaching materials. As a result, the assessment of the satisfaction and the contents of the lecture was particularly high.

Mechanics of materials is a key subject in the Department of Mechanical Engineering. In recent years, the teachings of the subject is to transition by changing the curriculum. In this study, to investigate the syllabus of material mechanics courses at the university. I will discuss the features of the current curriculum from the results of this survey. Different trends in curriculum content and the number of units was found in technical college and university. University whereas showed a trend of decrease in the number of units and selection, there was no significant change in the college curriculum.

This paper reports on creation of study program for a science experiment and handicraft classes aimed at elementary school students. In this program each student builds a paper airplane using ground effect and competes on the flight distance.
First we designed and manufactured paper template of airplane and gum-powered catapult-assisted launch equipment that were needed for execution of this program. Also, lecture contents were prepared to teach students how airplanes fly.
Using this program, we actually offered about two hours of science class twice. The result showed wing-in-ground effect craft was a suitable teaching material for beginners, because the airplane had simple structure that made adjustment for stable flight easy. But the program demands continual refinement so as to extract technical creativity from students.

This paper is checked the element division and the relations of the error. The shape that I analyzed is three kinds. The result that a way of the element division was important to fracture mechanics. It is necessary to do distance of the element division finely to give analysis precision. Particularly, I am careful about a value of the crack tip when I use FEM.

This study reports on error-block analyses and decoding method in the 4/9 two-dimensional recording code for holographic memories. The algorithm for zero-value determination of pixel levels was changed for improving bit error rate (BER) characteristics. In the algorithm, a block was determined to be the (0000) code block when all the four pixels,at which bright spots could be reproduced, exhibited lower levels than the threshold. In the numerical aperture (NA) of 0.14, a W-shaped deterioration in BER at threshold of ∼20% was disappeared. However, this method was not useful for reproduction in NA = 0.07, where errors occurred because of displacements of reproduced bright spots by optical interference between the spots.

Our research team has proposed the novel communication method for purpose of application to wearable devices. This communication uses the human body as a transmission path and two kinds of energy, electric field and ultrasonic waves are applied hybridly. Therefore, we call this method hybrid communication. To adopt the feature of those energies, this system can realize high usability and secure communication. In this study, I have particularly worked on the improvement of the accuracy on the ultrasonic wave communication. I have improved transmission error rate by changing the modulation method from the amplitude shift keying to the phase shift keying. In addition, I have developed the synchronization method suitable for the ultrasonic wave communication.

This paper proposes single inductor dual output (SIDO) buck and boost converters with a ripple based regulator. The proposed SIDO converter need no clock signal nor saw-tooth generator but use a triangular signal generated from the PWM signal. In simulation results, static output voltage ripples for buck and boost converters are smaller than 5mVpp and their transient responses are less than 10mV at 0.5 A current step for a buck converter and at 0.2 A for a boost converter. Line regulations are 5mV at E=10士1 V for a buck converter and 15mV at E=3.5士0.5 V for a boost converter.

In this paper, Prediction which uses Voronoi Tesselation which can predict Chaotic Time Series Prediction was performed. Furthermore, the new method of "the Correction Method using a Prediction Error of Time Series" was proposed. It is shown that Predictive Accuracy is improved by this Method. It is shown by using a Modified Method in the Middle of Prediction that an Improvement of Predictive Accuracy can be performed even from the Middle.

Septic tank is equipment for sewage treatment using microorganisms. The purpose of this investigation is to establish the treatment processes for highly concentrated wastewater including oil by the combination of septic tank and auxiliary equipment (bubble columns reactor). We evaluated and emphasized the performance of auxiliary equipment for wastewater treatment. Experimental data obtained from COD-Cr and BOD showed the degradation of carbon source by our bubble columns reactor.In addition, artificial waste water including oil (more than 500 mg/L) was not able to degraded, scum floated in equipment. As a result, it can be concluded that septic tank with auxiliary equipment needs detailed study to upgrade its performance for treating wastewater including oil.

Students are instructed reserve of the waste liquid to the waste reservoir according to the kind in the student experiments. However, they occasionally poured waste liquid into the different kind of waste reservoir. That have led to the environmental problems, safety problems and increase in processing costs. It is what the lack of knowledge of the hazardous substance in waste liquid. Therefore we tried an attempt for education of waste liquid in the student experiments.
