In the present paper, the raison d'$\^{e}$tre of geography and geography education in the humanities are explained. Geography was not considered as ontology notion and geography was also not aware of regarding ontology. However, human being is the geographic existence. People occupy the space they live in and reveal their own existence by virtue of the space. In geography, we understand human existence by concrete things consisting of the space. Geography can explain the necessity for the space of origin where human being had lost and open a gate to find their own existence through it. Geography education can find the justification as to why we should teach it in 'now here'. We can make a bright future in geography education in terms of critical reflection at the ontological dimension. Geography and geography education have clear reason to exist in right here. That begins from the question of what relationship between human and space is and completes the raison d'$\^{e}$tre based on the answer.

Prevention of thromboembolism is the most important task in the development of bioconpatible small caliber artificial vascular graft. In normal vessels, vascular endothelial cells maintain homeosatsis by secreting numerous factors. The aim of this study is to develope a method which Improves biocompatibility of small caliver polyurethane graft using endothelial cell culture technique, and ev luate the efTectiveness of extracelluar matrix for endothelization which was produced by cultured fibroblast. Methods ; Multiporous polyurethane tube of 3 mm diameter, 0.3 mm thickness was manufactured for vascular graft. Three mongrel dogs were intubated and internal jugular veins removed. Extracelluar matrix produced by cultured flbrobast which was obtained from dog's internal jugular vein were coated to the polyurethane graft. Then, endothelial cells extracted from Jugular vein were cultured and fixed on the extracelluar matrix layer of vascular graft. Endothelial cell coated vascular grafts were implanted to the carotid arteries of experimental dogs as interposed autograft. Implanted grafts were removed after 3 and 6 weeks. As a control, PTFE graft was interposed on carotid artery. These experiments demonstrated that extracelluar matrix produced by fibroblast can afford a base for endothelial cell linings of polyurethane graft. Although thrombosis were developed on autografted en othelial cell coated graft, 33% opening was noticed, and showed less adhesion to adjacent tissue layer. These findings suggest that fiboblast produced extracelluar matrix which can be used for edothelial cell lining vascular graft, and by improving the cultured endothelial cell function, there will be a new modality for reducing thrombosis on small vascular graft.

We examined research trends in geomorphology and hydrogeography in America based on papers presented at the annual meetings of the Association of American Geographers(AAG) and papers published in two AAG journals between 2002 and 2004. Among the 437 papers in geomorphology, $40\%$ of the papers concerned fluvial geomorphology, followed by environmental geomorphology and glacial and periglacial geomorphology concern. Among the 452 papers in hydrogeography, about $20\%$ of the papers focused on water, law and institutional aspects, followed by hydrogeomorphology and hydrologic modeling. Twenty one papers examining geomorphology and hydeogeography were published in two AAG journals, and fluvial geomorpholoy was the dominant theme. GIS was used for $29\%$ papers in geomorphology and $35\%$ of papers in hydrogeography($35\%$), suggesting that other methods, including geostatistics, field survey, and qualitative methods, are employed as well. This methodological diversification seems to be associated with solving such complex environmental problems as integrated watershed management and implies that geomorphologists and hydrogeographers are expanding their traditional territories and are making close connections with human-environment geographers and human geographers. Geomorphologists and hydrogeographers are likely to continue examining the causes of and solving environmental problems that humans are currently facing and might face in the future.

Geography as a field of learning had its beginnings among the scholars of ancient Greece. The emergence of modern Geography was much due to the collection and classification of information about overseas areas. Today, world regional geography, which may be called area studies in other social sciences, is regarded as an introductory geography course in many American universities. World regional geography, however, has been much neglected by Korean geographers. Many factors have made Korean geographers not concentrate their efforts to area studies. The exterior factors include the great expenses for the area studies' fieldworks, and the many geographers' involvement in the writing of geography textbooks and atlases for school students. The interior factors include all the ethno-centric, mysterious, and authoritarian perspectives a large number of Korean geographers strongly stick to.

The core version of UDC(Universal Decimal Classification) is available in an electronic form called MRF(Master Reference File) which supports the maintenance of the quality of the scheme as a working tool for the UDCC(UDC Consortium) by annual reviewing its content and initiating revisions and extensions. In this paper, we discuss outcomes of our in-depth analysis of the geography, biography and history disciplines in UDC focused on the its evolutions and characteristics, including the common auxiliaries of place, the common auxiliaries of time and the common auxiliaries of race, ethnic grouping and nationality. Based on the in-depth analysis, we suggested some ideas which can be applied into the history class of KDC(Korean Decimal Classification). In particular, its principle of combination methods in the history of individual regions, the way of its assignment of physical geography and human geography in the same division, the possibilities of the extension of the table of geographical division and the adaptation of the table of chronological division in KDC.

Geographical travel(Geotravel) is new theme tourism based on geographical fieldwork. Geotravel is an emotional journey to explore physical and human landscapes, and is also a comprehensive environmental one beyond the scope of historical tourism. Geotravel provides an optimized regional content and programs for experiential tourism of the family. Taking advantage of geographical characteristics as spatial tourism, the geotravel methodology in catchment unit is strongly recommended. The geotravel content has to be developed in convergence standpoint. The integrated key words of geotravel are human and water. Geotravel is a pattern of specialized edutainment tourism for the public and elementary, secondary school students as well. The development of geographical travel courses is necessary for the popularization of geotravel. Mobile apps will be the medium that delivers easy geographical travel information. And geotravel curator has to be raised quickly for the generalized easy and interesting geotravel.

Geography has played a role of serving as a bridge between the natural and social sciences for long time and can be an interdisciplinary framework. In this research, the effectiveness of an interdisciplinary approach centering on a geographical perspective in environmental education is presented. On this basis, a syllabus for seven 90-minute classes for the 8th grade is established under the topic of "Studying the Environment of Eighteenmile Creek." This interdisciplinary framework will be strengthened and vitalized through GIS, which plays an important role to make the geographic and environmental education more student-centered, active, and relevant to the world where we now live.
