In this paper, we review a variety of state-of-the-art research on assessment of the railway track capacity. We address the three well-known methods (Yamagishi, UIC 406, and TCRP-13) with individual case study in this research field. First, we explicitly present every derivation-step of the Yamagishi equations that has been most frequently applied in the Korean railway without clear understanding for it. Further, we present a prospective application scheme of the method as an analytic assessment method. Second, we address establishing process of UIC 406 standard and its application method, which is known as the standard method in Europe. Finally, we address the method and application of TCRP-13, and present comparison between the three methods. This paper is expected to contribute for improving understand on the in-using equations and methods in practice as well as for activating application of the internationally well-used method to the Korean railway.

Environmental problem and eco-crisis don't mean pollution itself any more, although general people have believed that environmental problems can be resolves by removing pollution. The mos important is environmental problems are linked with social structure which individualism, rationalism is extremely prevailed in the market oriented capitalism society, so public value is ignored especially. In the point of environmental education, this is very important because environmental education is not completed through schooling process, such s class learning, discussion. observation etc, but in the our practical life itself. This means that environmental education can be done by changing of lifestyle anywhere we live, and anytime. But any places governed our social life are polluted by efficiency pursuiting individualism in market oriented capitalism society. So environmental education can't hold the water in this system, in the aspect that we can't stimulate feelings of the student and general people, getting to public resource value and harmony with nature by throwing individual mind away. It is big problem. In this field, I have thought the unique space and social structure which can be used as environmental education place is small-planning community, such as Kibbutz in Israel, educational community Finhorn in Scotland, harmony community Yamagicism Village in Japan and DURE in Korea etc. For the research of this educational possibility in these small community, I visited and investigated immediately, and confirmed. In this thesis, I insist that the training process and practical life experience in this community themselves are good environmental education. So, in case of YAMAGICISM in Japan and FINDHORN in Scotland, DONGSASUP program in Korea, I introduce these small community environmental- education program.
