  • National parks are designated and managed for the purpose of preserving natural ecosystems, nature and cultural scenery, and promoting sustainable utilization in Korea. Since we designated Jirisan as the first Korean national park in 1967, we have now designated and managed 22 national parks. Because these national parks are the core protected areas of the nation and the ecological recreation center for the people, the interests of researchers related to national parks and citizens have steadily increased over the last 50 years. Especially, various natural science researches and social studies on national parks have been conducted with the launch of the Korea National Park Service in 1987, which is dedicated to national park management. However, we still lack research on national park research trends in Korea in spite of the increase in scientific research and public interest. It is important to know who and what institutes are leading national parks research, what research topics have been conducted, what kinds of researches are important in each national park, and how these researches relate to national park management policies. We propose a study to review the national parks related studies that have been carried out so far and identify the research trends. In the pilot study, we collected about 700 research papers on national parks published between 2002 and 2016 through the Korea Citation Index of Korean journals. We are analyzing the number of papers published, research institutes and research topics related to national parks. Analysis of these national park research trends will be necessary for efficient national park management and policy making for future generations.

  • As the pluralistic value in which various cultures and trends exist develops the world at large, development of interior design is required to examine consumers by group. This requirement purports to set up a strategic model of operating interior design organizations under cross-cultural (past and present) enviroment, not to express new researches of interior design following the direction of the developed media service. Based on the educational and complex cultural approach to design matters - the key issue in solving the cross-cultural design matters, this paper has suggested the structure of semi-centralized design process and the system for finding out consumers' trends under the new media-based cultural design environment. This study presents some expected effects. First, it will be able to enhance the consumer-oriented design mind by providing the information on the interior design system and design trend. Through analyzing the lifestyle in the 21st century and providing the relevant information, it will lead irrlprovement in living environment. And further, by using the program of searching consumers' new preference, the system of grasping consumers' propensity and making decisions will be materialized. Secondly, based on the background database of forecasted consumers' trends, marketing strategies can be established. Thirdly, through the better technology of designing living environment, efficiency will be increased and the economic foundations through use of new database will be constructed. Fourth, systematic interior design can be developed. Strategic correspondence to consumers' desires and reinforcement of competitiveness will become possible with development of database. By encouraging consumers' participation under digital environment, their trends can be forecasted, and by efficiently using information and new technology, resources can be saved and further, additional costs for promotion and sales will be reduced.
