    Macrophytes growing in Lake Biwa such as ofusa-mo (Myriophyllum aquaticum), sennin-mo (Potamogeton maackianus), okanada-mo (Egeria densa), kuro-mo (Hydrilla verticillata) and kokanada-mo (Elodea nuttallii) were characterized in their chemical composition in order to evaluate their potential as biorefinery feedstocks. As a result, cellulose and hemicellulose contents were found to be in a range, respectively, between 227 - 436 g/kg and 88 - 194 g/kg, while lignin content was from 71 to 175 g/kg. In more detail, hemicelluloses were mostly composed of xylose, galactose, mannose and arabinose in relatively equal amounts, whereas lignin was composed of guaiacylpropane, syringylpropane and p-hydroxylphenylpropane moieties, while ash and protein were remarkably high to be 105-223 g/kg and 137-229 g/kg, respectively. Although inorganics as shown by ash might be a limitation in the utilization of the macrophytes as biorefinery feedstocks, cellulose, hemicellulose, lignin and protein are available as raw materials for the production of a wide range of value-added biobased products.

    Recently, interest in natural power resources has been increasing. Because of this, we held a lecture using a movie as a medium to spread the knowledge that we have of natural power resources. We decided to focus on the topic of the wind power generator. In the lecture, we let participants make a model of the windmill and watch how windmills generate electricity. A pre and post questionnaire was given to each participant before and after the lecture to evaluate the level of change of knowledge of each participant regarding the wind power generator. From the questionnaires, it was apparent that the participants had changed their attitude toward the wind power generator during the lecture. Firstly, participants became more knowledgeable on the topic. Not only had their interest levels increased, but they also wanted to be more active in using this resource for energy. They felt encouraged to tell others about this resource and they also saw it as a potential energy resource in their own homes. We can conclude that the lecture had a positive effect on the participants and it worked in helping them become more knowledgeable and aware of using wind power generators as an energy resource.
