The environmental problem in the vessel exhaust emissions is getting severe every year. In 2016, the 3rd regulation is planned by the IMO (International Maritime Organization). This has to be reduced by 80% of the amount of discharge for NOx in ECA (Emission Control Area). This research is about reducing NOx and PM. Using emulsion fuel is reduced in NOx and PM, using exhaust gas charger and static electricity water splay by corona discharge is reduced in NOx and PM, the experiment which combined these two technologies is conducted. PM can collect according to the static electricity power by spraying electrostatic water. O3 emanating from corona discharge can be converted NO into NO2, NO2 can be melt into water well. Moreover, by raising oxygen concentration by 20%, and not less than 80% of NO we have changed the oxygen concentration into NO2. As a result, NOx has been reduced by 85 %, while PM by 100%.

Our Hiroshima National College of Maritime Technology is located at a small island off the mainland. Due to declining population and birthrate, the number of applicants between 1998 and 2009 was only 1.2 to 1.5 times of the quota. In addition, some successful applicants declined, which resulted in the chronic shortage of newly-enrolled students. In order to increase the applicants, all Departments of the College have been cooperating for these several years in building systematic publicity work in the extensive area. As a result, the number of applicants tends to increase. We evaluated and analyzed our publicity work for these several years and will report the future focus of the work as even hardersituation is expected ahead. We intend to develop our publicity work so that our Collage can be the school of choice for the “students of special nomination” who have their definite goals. This paper is an interim report for our further activities.

In learning of the issue of vibration, it is important to know the essence of problems like resonance, natural frequency, natural vibration mode and so on. However, it is hard to really understand these phenomena very much. So, the authors developed an experimental equipment of rectilinear vibration system with three degrees of freedom for the purpose of observing vibration of mechanical systems(with special attention on resonance and natural vibration mode). In addition, we simulated this vibration system by using dynamics simulation system for teaching (DSS) and determined the optimum configuration of machinery. The main conclusions are obtained as follows: using the developed experimental equipment, we clearly observed the primary, secondary and tertiary resonances and natural vibration modes; the results of vibration simulation using DSS agreed very well with the experimental results; it was very effective to use DSS in the development of the experimental equipment for observation of vibration phenomenon.

The students belonging to Hiroshima National college of Maritime Technology hold a meeting for discussing on the nuclear power. The participantsin the meeting are students, the local people who live around the college, experts on nuclear power plants and the college’steachers. The main subject of the meeting isthe problems of nuclear power and energy after the serious power plant accident at Fukushima.

This paper considers classification of knots of ropework.To do so,invariants are used,which have been　introduced in knot theory. It is necessary to close the knot and to extend it to conform to the reality,which is　ｐroposed in this paper.It is argued about ambiguity occurred then.

The practical training aboard a training ship is considered as a major issue among the maritime educationssuch aslectures, exercises and trainingsfor the students. However, from the financial point of view, it will be difficult for each school to own itstraining ship in the future. In order to improve thissituation, the principal framework has been examined for the new maritime educationalsystem with one training ship, as an example, among the three National Colleges of MaritimeTechnology in the Seto Inland Sea. We are going to propose a new model for the maritime education with one training ship for three schoolsin which the studentsfrom each campus will move in each small fast boat, and will aboard in the training ship which will be stationed at one port in the Inland Sea.

We investigate “Pilot accident”, accidents which happen while pilots are guiding, and present a measure to reduce any kinds of marine accidents. This paper could contribute to a pilot education in the future. And then, the countermeasures could extend to an ordinary vessels as well as pilots on board vessels.

Global warming has caused environmental problems all over the world; it is an exigence to reduce greenhouse gas emission to stop global warming, and at the Conference of the Parties of United Nations Framework Convention on Climate Change itsreduction was discussed. While the greenhouse gas emission in business sector has already been reduced to almost the same level as 1990, that in public sector has been increased by 2.5 times, which means public sector still has to find some way to reduce greenhouse gas emission. A school, being in a public sector, can have some action for the reduction with an educational effect to students. This paper presents the environmental load in our school, and it is shown the result of greenhouse gas reduction program we tackled.

This paper describes a system which displays information embedded in a two-dimensional　ｃode in real-time using augmented reality. In order to retrieve information from a two-dimensional code, users need to take a still photograph. This is not a convenient way for the users, because they need to wait for a few seconds to take the photograph. Therefore, we developed a system which is able to display information of two-dimensional code in real-time without taking a still photograph.
