Hundreds of books and thousands of pages of museum journals are available to a person who wants to know museums , it is actually due to their various contents and objects in the museum history of a growth of several centuries. The traditional museums were recently defined in the concept of "A non-profit permanent institution , in the service of society and of its development , and open to the public , which acquires , conserves , researches , communicates and exhibits , for the purpose of study, education and enjoyment, material evidence of man and his environment. And the traditional museology has well extended and reproduced this concept using the techniques of museography But the original concept of the term museum has been derived from a Greek word museion with meaning of 'Sanctuary of Muses , the goddesses presiding over all learning and art. Hence , the inherent quality of the pursuit of learning has , in one form or other, been retained by museums all over the world as theMuses with which glorious events of the past, folk art , music and poetry, gaiety and harmony were associated. However, the traditional museum and museology couldn t be enough secured the originality. Through the developing process of the traditional museum history, now we are on the new phase to restore the original Greek museion s meanings , which is the cultural transmission system to use a concept of 'Musealization( =Museological Observation)" using all museographical tools. It is a movement to go to the original places or to grope a coexistence with ecological environments and to serve human and nature as a museological mediator( = museum & museologist) in the society of the local community, as Prof. Bedekar(995) gave a following concept of "New Museology, which is the theory of the human attempts of collecting , protecting, using such evidences , which cannot survive in their original situation , but which are essential or indispensable , even irreplaceable , in knowing by means of reality through his own identity. Such evidences can be found , collected , protected , interpreted by many alternative means , which can be invented by societires according to their needs ." It has to be actualized through a 'museological observation( = Musealization)’ in the field of ‘Museological Transmission' by museological mediatod =museum & museologist). This is some new museological meanings used in this paper'beyond the science of such traditional museums . For the concept of the above new museological approach , 1 did a field work to Exiled Tibetan s Cultural Reconstruction as an example of the 'Museological Observation (= Musealization) ’ in the actual place of ‘Museolo- gical Transmission' . And through the field work, 1 could be found that museums and museologists as a cutural mediator can intermediates between a cutural evidence with its ecological environments and their cultural identity using museological approaches. Futhermore, 1 could be given 'a proposal to an 100 years far-reaching policy of Korean Museums in prudence , which can be actualized through the adaption of the change of the traditional museum and its museological concept into the above new museological approaches. It may also be a strengthening way of the nation' s competitiveness using the newmuseological professionals( =cultural mediator) for the far-reaching future.
