Introduction : It has been reported that the survival of low-grade glioma patients depends upon the time of malignant transformation. The authors presents the clinical analysis of histologically proven trasformed gliomas. Materials and Method : A total 92 patients who were consecutively treated and histologically confirmed hemispheric low-grade gliomas between 1980 and 1998 were analyzed and followed. All cases meet the criteria of WHO glioma classification of grade II. Results : The mean follow-up period was 73 months. Twenty two among 92 cases(24%) were histologically proven to be transformed into malignant ones. The mean time to transformation was 56 months. The 5-year and 10-year survival rates of the transformed group were 66% and 30% respectively and significantly different from the survival rates of the non-transformed group(p=0.0018). Among clinical factors at presentation, the initial tumor volume had a tendency to be larger in the transformed group than that of the non-transformed group and became significant when it was divided into more than $30cm^3$ or not(p=0.02). Among therapeutic factors, the extent of removal had no influence on the rate of malignant transformation. But postoperative radiation therapy were more frequently given to the pre-transformed group than the non-transformed group and the frequency was significantly different(p=0.02). Conclusions : The authors had found that the initial tumor volume and radiation therapy could be clinical prognostic factors for the malignant transformation of low-grade gliomas.

The Analytic Hierarchy Process (AHP) is known as a very useful decision-making model developed for obtaining the relative weights of alternatives through pairwise comparison in the context of hierarchical structure. In this paper, we propose a method to reflect the reliability of evaluators in the process of pairwise comparison. The method is applied to the evaluation of aerospace technology alternatives. We have conducted a questionnaire survey for S company that is one of the representative aerospace companies in Korea. A questionnaire was designed for obtaining both the priority with considering the reliability of evaluators' importance weights (the modified AHP priority) and the priority with assuming equally reliable evaluators' importance weights (the AHP priority) in order to compare the priority derived by each of two methods. The result shows that there exists the difference hard to neglect between the final priorities gained by two methods.

The study was designed to forecast and derive future core technologies using Delphi method for the postharvest management in Korea. The target of the survey for Delphi is confined to specialists in the area of postharvest technology. Sixty-three core technologies for the future were first derived through broad survey by 12 specialist panels and Delphi survey was performed on the selected technologies based on the answers from 23 specialists. Questions were given to each specialist groups corresponding to the selected technology in order to survey importance, realization time, level of research and development (R&D) in Korea and foremost country, leading group of R&D, effective policy, etc. Realization time expected was within the year of 2010 for all the technology. Time differences from that in developed countries were 0 year for 5%, one year for 22% and two year for 44% of technologies indicating that level of postharvest technologies in Korea were close to that in the developed countries. Among the 6 sub-class areas of postharvest agriculture, importance index was highest, reaching 78.4%, in the area of quality control. In contrast, technology development level was highest in the area of distribution, which was evaluated as 66.8%. Combined analysis of the importance index and the development level suggests 16 technologies which have high developing potential. More than 50% panelists preferred industry-university-research center cooperation as a desirable approach to technology development. Likewise, most preferred technology developer was industry-university cooperative. As the most basic supporting policy for technology development, expansion of research fund was ranked on the top receiving 34% positive answers. The results of the present survey could be used as a strong tool to make agriculture for core and strategic industry that has high value-added in the 21st century. 본 연구에서는 우리나라 농업을 21세기 고부가가치의 전략핵심산업으로 발전시키기 위한 일환으로 유통분야 23명의 산, 학, 연 전문가를 대상으로 델파이조사를 실시하였다. 델파이조사의 기초가 된 미래유망기술로는 유통분야의 전문가를 대상으로 실시한 기술수요조사, 문헌을 중심으로 한 문헌조사, 유통분야 12명의 전문가로 구성이 된 전문위원회를 통하여 63개의 기술이 도출이 되었다. 이들 과제에 대한 델파이조사에서는 각 기술의 미래실현시기, 중요도, 그리고 우리나라와 선진국의 연구개발수준 등에 대한 설문조사를 실시하였다. 도출된 기술의 실현시기로는 63개의 기술 모두 2010년까지 실현될 것으로 예측이 되었다. 이 중 선진국과 실현시기의 격차가 전혀 없는 기술은 5%, 1년이 늦은 기술은 22%, 그리고 2년이 늦은 기술은 44%로 나타나 유통분야의 기술수준은 선진국의 기술수준에 근접해 있는 것으로 나타났다. 기술의 중요도지수를 중분류 영역별로 살펴본 결과는 ‘품질관리’ 영역이 78.40로 가장 높게 나타났으며, 중분류별 연구개발 수준은 ‘물류’ 영역이 66.84%로 가장 높게 나타났다. 중요도와 연구개발수준을 함께 살펴본 결과 유통분야에서 연구개발수준이 높고 중요도도 높은 것으로 나타난 기술은 16개 기술로 유통분야의 기술 중 가장 성장 잠재력이 높은 기술로 나타났다. 연구개발 추진방법으로는 ‘산학연협동’이 51%로 가장 높았고, 연구개발 주체 역시 ‘산학협동’이 가장 선호되었다. 이 기술에 도달하기 위한 정책수단으로는 ‘연구비확충’이 34%로 가장 높게 나타났다. 이 조사를 통해 이루어진 미래기술의 중요도 결정, 연구개발수준이 높은 핵심기술 선정 및 연구개발 추진방법과 정책수단의 도출은 농업유통분야의 육성발전을 위한 정책적 지원대상 파악 및 국내 유통분야의 연구개발정책을 수립하는데 중요한 기초자료를 제공할 것으로 기대된다.

기술예측에의 적용을 위한 상호영향분석법의 이론적 고찰: 한계와 연구방향

One of the systematic attempts for technological forecasting is Delphi Method that externalizes and manipulates unformalized experts opinion in a particular problem or subject. It has, however, a critical shortcoming that it can not reflect the degree of interaction that exists among forecast events or subject. Gordon and Hayward (1969) criticize that when the forecast events are strongly interrelated, a totally unrealistic consensus may result. They proposed a new forecasting method that considers the interaction of events, that is, Cross Impact Analysis (CIA), A number of related models have been developed after them. In this study, we examine a variety of research results related to CIA obtained by literature survey and propose the limitation and future research direction. This analysis would be expected to help us to create a strategic scenario on future technology development at the government and firm level.

The imports of used medical equipment such as CT, MRI have been rapidly increased every year. How to manage those medical equipment has been one of critical issues in the government sector. In this study, we demonstrate how benefit/cost analysis using the Analytic Hierarchy Process (AHP) can be applied to the comparison of used CT/MRI and new CT/MRI. The final results show that the new CT/MRI is more attractive than the used CT/MRI.

Recently, due to the primary emphasis of health industry and to the restriction of budget, setting the priorities for effective and efficient investment on the medical device and material products has been one of the critical issues in the government sector. This paper shows how an Analytic Hierarchy Process (AHP) model can be used for assessing selected medical device and material products for grant of the Ministry of Health & Welfare. The final results show that unabsorbable suture is the most attractive medical device product among 88 evaluated products, followed by IV cannula, central venous catheter.
