Abstract In this paper, the practice of the Robot Contest using waste materials in Hiroshima National College of Maritime Technology has been introduced. Robot Contest is one of the very events of engineering education at colleges of technology. However, making a robot is not easy. Also students take interest in it positively. Such situation is a good chance to educate them as an engineer. As one of educational activities in College of Technology, its effects for engineering education should be evaluated. Robot Contest has an educational effect not only on engineering education but on engineering spirit cultivated by effort of trial, cooperation and sympathy for other people

In learning the issue of vibration, it is important to know the essence of the various problems in resonance, natural frequency, natural vibration mode, and so on. However, it is really very hard to understand these phenomena. So, we started to develop the experimental equipment for the purpose of observing the vibration of mechanical systems. In the previous study, it was reported on our horizontal shaking table. In this study, the vertical shaking table was made successively. Then an experimental equipment for vehicle vibration of bouncing and pitching was developed. By using this apparatus, we clearly observed the primary and secondary resonances and natural vibration modes.

However, it is really very hard to understand these phenomena. So, we started to develop the experimental equipment for the purpose of observing the vibration of mechanical systems. In the previous study, we developed the horizontal and vertical shaking tables respectively. In this study, the vibration model consisting of concave rigid body and solid cylinder was made as an example of using the horizontal shaking table. By using this model, we clearly observed the primary and secondary resonances and natural vibration modes.

t is very important to solve a lot of practice problems related to uniform motion and uniformly accelerated motion in order to acquire the basic knowledge of dynamics. In particular, the displacement-speed-acceleration relation is one of what students must understand by all means. In many teaching materials such as school textbooks, the solutions are generally calculated by using basic formulas. However, we know the fact that many students relying on the formulas cannot master the basic knowledge of dynamics. In this research, in order to help such students, we tried to solve a lot of practice problems related to uniform motion and uniformly accelerated motion by using a graphical method without using formulas.

The open seminar (2013, 2014) of National Institute of Technology, Hiroshima College was held on a theme of electronic and control engineering for Junior high school students. The authors has developed a educational material of programing workshop using microcontroller and matrix LED for the seminar. The attendance student can experience the basics of programing work of matrix LED by assembling the educational material. This report describes development of the educational material for applying to the open seminar in 2013 and 2014.

The radiations can’t be seen with naked eyes. To see the radiations several devices are used. We tried to visualize the radiation with a web camera and image analysis software. For visualizing the radiations, we stored data from a web camera for two minutes and all the data is overwritten in one picture. In the picture, we found a few spots and we think those are the trace of radiations.

We describe the execution that observed coastal seawaters usin the observation equipment by the experiment of the student. The purpose is to give the student learning the problem of the island en-vironment and the opportunity when the student examines the problem of the island. In addition, we developed the system which monitored the data of the coastal seawaters in real-time. This system can get the environment data of the seagrass in real time by the buoy connected to the wireless network.

From 2012, In the Hiroshima National College of Maritime Technology, I introduce moral education as a new curriculum. Breeding and fixation of the model awareness are necessary to bring up the talented person who can play an active part as a member of society. In this article, I consider the location, local climate, culture, difference in education environment whether a local difference has an influence to model characteristics. I weigh the history, economy, the education system and, about difference in model awareness, speak consideration. The factor of the human being formation to let you breed normative consciousness understood that volunteer activity and the third generation household were concerned.

This paper considers the current condition of Japanese Islands, which is consistence of 6520 island, including 5 main lands. The paper observes the variation of islands and the economy of islands. From view point of population, dimension, structural differences of industries, and the author determines the several types of island economies. Also, the author prospects the future of the study and the Islands itself.

I designed a line tracer kit to be used in the engineering experiment for student. This kit is composed by low cost and readily available parts. Rechargeable batteries supplies power of 6V to the circuit and motors. A photosensor with photoreflectors, witch was made by the second grade students, reads the line drawn on the ground. PIC microcontroller controls the moving by the line information, and two motor is driven by the monolithic IC, respectively. By repeating the re-design, wiring diagram of the circuit board became simple. In this paper, I shows the circuit design process to aid our future engineering experiment.

As an example of Osaki-Kamishima, it is thought that there are a tidal wave and sediment disaster by a typhoon and a seismic sea wave as large-scale disaster. The disaster control plan is reconsidered as Nankai Trough Quake which will occur in recent years caused serious damage to the Pacific coast. DIG (Disaster Imagination Game) is one of a method to reconsider the hazard map. DIG is the disaster drill on hazard map that the residence reconsiders about a road and a building, disaster facilities, geographical features. So, it has lately attracted considerable attention, as it helps to enlighten a disaster measures. This paper considers about making a hazard map electronic using a method of Disaster Imagination Game.

The feature of the radar reflection intensity from a small boat is shown experimentally. In this research, we carry out an experiment with the small boats using a developed radar image converting system that outputs reflection signals in 12bit, and find the following. (1) A fixed object shows stronger reflection intensity than small reflection object such as a small boat. (2) A small boat with a reflector shows stronger reflection intensity than that without a reflector. (3) The power ratio with a reflector becomes larger by some 10 – 20dBm, which shows the reflector works effectively.
