There are more than 4 million automatic vending machines in Japan. They cause environmental problems such as the waste of electricity ,litter disposal. Some are hazardous to pedestrians due to protrusion into the roads. Nishi-Harima life science center of Hyogo prefectural government hosted the ' 94 Nishi-Harima environmental seminar consisting of 12 days of lectures and environmental surveys for citizens' lifelong education. I was responsible for a survey concerned with automatic vending machines. In this paper, I focus on the learning effect for students by using the survey, and solving the problem of managing such a seminar. Results of the survey show that 70% of students understood the problem regarding the waste of electricity by automatic vending machines, but 16% of students felt the necessity of such machines. I think it's very important to discuss more thoroughly the questions of 'How many?' , 'What kind of?' and 'How should we use them?' , and how to be environmentally conscious about our daily life. Regarding the survey method on automatic vending machines, some items, such as measuring of the survey area, taking the temperature around the machine and taking photographs, should be improved in the coming seminar.

The remaining natural lucidophyllous forests are found mainly in the sanctuaries around shrines and temples as fragmented forests (isolate dforests) .These forests are disturbed by human impact and the effects of isolation. In order to conserve the lucidophyllous forests, the actual conditions concerning flora, number of species, species diversity, species composition, dominant species, area and environmental conditions of the forests, were investigated. Initially we reported on eighteen forests in the Hokusetsu and Higashi-Harima areas. We would like to continue to report on the results of our investigation in the future.

Various geological materials and data have been accumulated in Hyogo, including geologically famous and important items to Japan and other countries as ・ 'Cu-bearing, metallic ore mines represented by Ikuno and Akenobe ; the Eocene to Oligocene Kobe Flora, significant to Cenozoic floral history in Japan as well as East Asia ; basalt of the Genbudo from which the Japanese basalt, Genbu-gan, is derived and also with which the Matsuyama Reverse Epoch is deeply concerned, and many others. They should be systematically compiled and stored for further study of geological and related sciences. Our museum has collected, examined and registered numerous data concerning natural history and environmental sciences, mainly obtained in Hyogo, in co-operation with many workers prior to the opening of the museum. The present series compiles fundamental geological data in Hyogo which have been collected through a systematic survey from 1990 to 1992, in addition to a recent supplementary survey. It contains eight independent serial data files on : (1) Microfossils ; (2) Paleozoic and Mesozoic Macrofossils ; (3) Cenozoic Macrofossils ; (4) Plant Macrofossils ; (5) Late Cretaceous to Paleogene pultonic rocks ; (6) Mineral resources ; (7) Late Cenozoic volcanic rocks, including newly measured K-Ar age and thermo-remnent magnetism, in and around the Tajima district ; and (8) Quaternary outcrops in the eastern part of Harima district. Files (1) to (4) are included in this volume and (5) to (8) will be published in Humans and Nature, No.6. Prior to exhibition of each data file, this paper remarks on the geological data dealt with in file s(1) to (8) and their significance ,and outlines the general geology of Hyogo.
