  • 편익-비용분석은 국립공원 보전과 같은 공공투자 정책의 상대적 가치에 관련된 정보를 파악하는데 매우 유용한 분석도구이다. 편익과 비용이 화폐단위로 계산될 수 있으면 순편익을 계산하여 공공후생을 최대로 얻을 수 있는 정책적 대안을 규명할 수 있다. 그러나 국립공원에서 파생되는 재화와 용역은 일반시장에서 판매되지 않기 때문에 국립공원의 보존정책 결과를 금액으로 계산하는 것은 그리 쉽지 않다. 이 경우 비시장재의 편익가치를 측정하기 위하여 이선선택형 가상가치평가법이 가장 널리 적용된다. 본 연구는 이선선택형 가상가치평가법의 일종인 Turnbull 분포무관모형을 이용하여 월악산국립공원의 경제적 가치를 추정하고 최종적으로 자산가치를 평가하였다. 평가결과, 연간이용가치는 65억원, 연간보존가치는 1,374억원으로, 프로우(flow)인 연간총가치는 1,439억원으로 추정되었으며, 스톡(stock)인 총자산가치는 약 3조217억원으로 평가되었다.

  • Unfortunately, we have poor knowledge of medical technology in North Korea. This study has thus attempted to identify the level and status of medical technology development through analyzing the contents of medical textbooks currently in use. This study has assumed that three factors are influencing the level and status of medical technology in a society ; the level of socio-economic development in general, the level of scientific technology revolution and health policy. Forty textbooks are collected for this purpose. The main findings are summarized as follows : 1) North Korea s strengths in that (1) its herb drugs, which are in a broad use, are cheaper, more safe and more attainable than bio-equivalent chemical ones, and (2) the development of its medical technology was carried out with emphasis on the practical and basic health needs. 2) North Korea has weaknesses in that (1) its medical diagnostic method largely depends on manual procedures, (2) the R & D investment in the development of chemical drugs, especially antibiotics, is very small, (3) the amount of medical equipments is in a absolute shortage, and (4) the medical technology is destitute of specialty, caused mainly by the overemphasis on Juche-Uihak or herb medicine. 3) Medical technology has two faces, positive and negative so that it cannot be successfully evaluated by one. It eventually acts a positive function for public health through developments of drug, equipment and new medical treatment method. But it is also true that it has negative effects such as the dehumanization of high cost medical technology, cost hike due to over-investments in expensive equipment and the absence of wholistic care from overspecialization. 4) We have to consider economic status and the social needs of medical care in order to evaluate the medical technology of a society. It is also the case with North Korea. A whole picture of the North Korean medical technology could be understood only if further comprehensive studies of medical technology are to be carried out for North Korea.

  • The purpose of this study is to identify (1) the successful quality management activities of domestic enterprises contribute to enhancing both corporate and national competitiveness and that the corporate and national competitiveness are related each other; (2) and to have the government and the citizens as well as enterprises re-recognize the importance of quality management and encourage them to make aggressive investments on quality management. It was found in this study that the enterprises with quality management scheme showed better performance that those without quality management activities. It was also found that quality competitiveness is a key factor for the enhancement of the national competitiveness, and that although quality improvement is normally realized through efforts of private enterprises (a conventional paradigm), active government support and participation are absolutely necessary for the competitiveness of the nation and industries. Accordingly, the quality management should be recognized not only as part of business improvement activities, but as nationwide activities where public sectors including government enterprises, hospitals, schools, regional governments, media companies and citizens groups are involved. In order to build a high-quality nation in the 21st century, the quality improvement should be realized through concerted efforts of the people, enterprises and the government.

  • Various studies and business investments have been performed on UAV in the field of spatial information industry, and it is judged that this industry has being evolved into an expansion stage as a legalization progresses. In addition, public institutions such as Korea Land and Geospatial Information Corporation, Korea Expressway Corporation, and Korea Land and Housing Corporation which have relatively much utilized spatial information work have entered into the stage of settling with active introduction for reasons of work efficiency and business management. However, surveying drones are still classified as expensive equipment, which is a burden on general business application and technology popularization. Moreover, the stabilization of reliability of various location information acquired from UAV is a part of ongoing research and supplementation. Therefore, in this study, to use image information acquired from low-cost UAV as reliable spatial information data, the flight altitude was changed and compared with the result of double transverse flight with conventional photographing technique. As a result, there was no change in the result value at low altitude, but the result showed more than 30% accuracy and accuracy improvement for the X, Y value at the altitude of 130m or higher than the conventional method.
