Abstract
For the university students majoring in environmental sciences and others, the questionnaire about the terms of environmental sciences are performed in the Nagasaki University. The results are compared with the past results that was performed for the agricultural students at the Kyushu University in 14 years ago. As a results of this study, most of the knowledge about terms are declined, however current student have more knowledge in some terms more related to environmental issues such as natural energy and hybrid car. The results of the questionnaire were classified into 8 groups by using the Self-Organizing Map (SOM), then the map and radar-chart were drawn to investigate characteristics for each group. As a results of the SOM analysis, the difference between environmental and the other students are clearly investigated. We confirmed that the SOM is useful tool to classify a results obtained from the questionnaire.
