$B!!(BEducation for Sustainable Development in higher engineering education in Japan.
$B!!!!!!(BNaohiro GOTO (Toyohashi University of Technology)
$B!!(BEducation for Sustainable Development (ESD) is education to make people learn social issues, find solutions and carry out them for establishing sustainable society. Since 2005 United Nations Decade of Education for Sustainable Development has implemented, then much attentions are paid by a lot of educational institutions. Higher engineering education institutions, national colleges of technology and technological universities, also have tried to include ESD subject and items in their own curriculum. ESD includes not only environmental education but also the North-South Problem, human right, gender issue and so on. Continuity between traditional engineering education and ESD is not clear, then method of ESD is different among the institutions and depends on individual sense of mission. One of educational objectives is to make people be independence. Engineering education is useful for independence as an engineer. Engineer requires knowledge and skill for specialty. In current curriculum of higher educational institutions, subjects for specialties, especially technology, are emphasized. On the other hand, in era of globalization, knowledge of sustainable development (SD) is also essential. So education for engineering should be integrated with ESD. Problem is how to include subject of SD and how to construct program. Introduction of ESD is not only to make independent subjects for SD but also to distribute items for SD in other subjects. ESD for engineering should recognize that SD is achieved by technology. Ability to predict effect of technology on life should be required, how to preserve life environment and how to improve convenience. To do that, it is important to assess the technology quantitatively by some tools such as life cycle assessment, material flow accounting and so on. ESD for engineering is developing. However integrated between ESD and engineering education has not systematized. We should establish system of ESD as soon as possible.

$B!!(BGlobal warming, energy crisis and environmental impact are hot issues for humankind in recent years. Worldwide, tropical countries are now concerned with production of renewable energy from local area biomass for decreasing the usage of petroleum energy and for reduction of green house effect gases (GHGs). Construction of sewage treatment systems for decreasing environmental impact, water environmental monitoring, urban planning, green society, energy conservation, etc. for creating a human environment which is friendly to life are being promoted globally. "Think Globally, Act Locally" is a concept that the Environmental Systems Engineering course at Nagaoka University of Technology always teaches to students. After graduating with doctoral degree in Energy and Environmental Engineering at Nagaoka University of Technology, Japan and returning to my birthplace, Thailand, this idea still stimulates research. On going projects "Development of Co-Benefit Treatment System of Molasses-base Wastewater", co-researched with National Environmental Studies, Japan and "Innovation of Next Generation Water Resources Recirculation Technology and Activation of Sulfur Cycle Bacteria Function Enabled for Application in a Developing Country", co-researched with Nagaoka University of Technology and the student exchange program between Nagaoka University of Technology and Khon Kaen University, will be introduced.
|S-4||$B!!(BPresent Status of Ecofriendly Organic Photovoltaic Devices

$B!!(B It is very well known that in the present time nothing could compete the Silicon (inorganic) photovoltaic devices, but in the time to come when the demand of energy will increase manifold and these devices will play havoc because of their non ecofriendly processing techniques resulting in large amount of carbon emission. This is going to pose a great threat to the human beings. Organic solar cells have bright future in comparison to silicon based solar cells in view of their low cost and their environmental friendly processing techniques. Presently the main problems, which are prohibiting their commercialization is their low efficiency and low stability. There is need to raise their efficiency from the present ~ 5% to ~ 7-8% and operating life > 2 x 104 Hrs. Keeping this is view we have designed and studied organic solar cells with different sructures(bilayer, bulk heterojunction) and different materials like P3HT, P3OT, PCBM, C60. Bulk heterojunctions are preferred over bi-layers because of availability of larger surface area. We have studied: ITO/PEDOT:PSS/P3HT :PCBM/LiF/Al and similar structures in which active layers were coated by spin coating technique The main problem with these cells are (i) low efficiency 4-5%(ii) low shelf life ~ 103 Hrs. Low efficiency is due to low mobility of charge carriers, bad morphology of the film, poor donor acceptor charge transfer, pin holes at the polymer-electrode interface and low shelf life is due to various degradation mechanisms: degradation of polymer (due to moisture and oxygen in the atmosphere), degradation at various interfaces, degradation of the electrodes, formation of donor-acceptor complex etc. We have addressed these problems and here we would like to present how have we been able to continuously improve the performance of some of these structures by making changes in their structures and optimizing various parameters like thickness of the active layer, solvent, donor-acceptor ratio, spin speed, annealing temperature and duration,. An introduction of futuristic approach will also be given. Some suggestions for further improvements will also be made like introduction of Single walled carbon nanotubes-to increase the spectral range and to provide percolation paths to the carriers, use of high molecular weight P3HT nanofillers to reduce degradation etc.
$B!!(BJump to the unknown world! - Development of a new sewage treatment system and revealing the function of microbes-

$B!!!!!!(BYAMAGUCHI Takashi (Nagaoka University of Technology)
$B!!(BAs the world at large faces the threat of global warming, carbon-neutral technology has attracted considerable attention in recent times. We have been developing a novel sewage treatment system that is energy-efficient as well as productive and have been applying this system in developing countries. A pond system is generally employed in these countries in order to save wastewater. However, since a pond is an open system, it discharges gases that contribute to global warming, such as carbon dioxide (CO2) and methane (CH4). Our novel system leads to a decrease in emissions of these gases. Some of our ongoing projects are briefly mentioned below. In India, we have been operating a reactor for improving the water quality of Yamuna River in the long term. In Thailand and Vietnam, we performed a study for processing wastewater from natural rubber industries. Furthermore, in Malaysia, we examined the disposal of liquid waste from palm oil processing plants. We dispatched a student to the spots and conducted onsite testing. Wouldn't you like to travel to places that you have not explored so far?
$B!!(BObservation about my overseas internship

$B!!(BThe world is in a period of globalization now, and it is necessary to acquire the international perspective for engineers. I'm a student at Toyohashi University of Technology and our university has the system of overseas internship. This system is very effective in acquiring international perspective and English language skill. At the beginning of this year, I did the internship in Finland by using this system. Though there was uneasiness in life in foreign countries, I was determined to try it. My first experience in overseas life gave me a lot of surprises. I had a very hard time though I became accustomed to a different language, the climate, and the culture, etc. And I was able to experience a lot of wonderful activities. I was especially interested in the difference between Japanese student's ideas and theirs. They hold an opinion of their own firmly and they are able to express it clearly. In addition, they understand their responsibility well. I was made to notice such a sense of responsibility lacking in me. I want to take the responsibility for my own speech and behavior firmly from now on. Moreover, the exchange with people of various nationalities was very valuable for me. I was able to feel the culture in various countries thanks to them. These experiences will surely be useful for my future. However, it is also true that I was deeply disappointed by my lack of English language skill from beginning to end. Therefore, I felt the strong necessity for putting more efforts to learning English.

$B!!(BThe project given to me is to program the NXT intelligent brick. Using any of the many programming languages, I am supposed to program the NXT brick to balance on 2 wheels. It is known as NXT inverted pendulum or NXT Segway. NXT is a programmable brick created by Lego Mindstorm. Legos has also includes the motors, light sensor, sound sensor, touch sensor, ultrasonic sensor and many more to enhance the robot movement and action. The NXT robot is able to connect 3 motors and 4 sensors at one point of time. With the help of online guides and tutorials on the different type of programming language, programming the NXT has become less complex as the guides are very helpful for starters.
