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.

본 연구는 정부 연구개발 사업이 갖는 고유한 기관 특성을 실제로 평가에 반영하면서 지난 6년간의 식약청 연구개발 사업을 새롭게 조명해 보는 것을 목적으로 한다. 즉, 식약청의 연구개발 성과를 보다 올바르게 이해하고 평가할 수 있도록 식약청의 특성에 맞는 구체적인 평가기준을 제시하고, 그 것에 의한 성과평가를 실시해 봄으로써 식약청의 연구개발 사업을 평가하는 새로운 틀을 제시해 보고자 한다. 또한, 식약청 사례를 통하여 정부 연구개발 사업의 책무성과 지속성을 동시에 담보할 수 있는 새로운 관점과 시사점을 제공하고자 한다. The purpose of this report is to suggest a new set of evaluation criteria which emphasizes the aspects of outputs and outcomes, and, therefore, reflects a portion of unique features of the KFDA's R&D programmes. Using the criteria, we demonstrate that the overall performance of KFDA's R&D programmes should be re-evaluated, and underscore that the characteristics and mission of a specific institute is also important in evaluating its performance. The results reveal that the overall performance of KFDA's R&D effort is more positive than what has been known. This difference essentially stems from the difference between the present that are universal but stiff and the suggested criteria that are based on missions of and results possibly achieved by the institute. In this regard the approach used in this case study could be taken into account in improving the evaluation system of government R&D programmes.

본 연구에서는 우리나라 농업을 21세기 고부가가치의 전략핵심 산업으로 발전시키기 위한 일환으로 유통분야 23명의 산, 학, 연전문가를 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. 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.

Recently, it has become important to establish a technology appraisal system because of increasing a service of technology credit guarantee. Also, there have been many efforts to evaluate a technology in the advanced countries. The technology/credit appraisal model which can measure firms` performance was suggested by Small and Medium Business Administration. In this paper, we analyze a structural validity of the model by confirmatory factor analysis and estimate the model which can distinguish whether an investment is possible or not by discriminant analysis.

박상운,조근태,Park, Sang Oon,Cho, Keun Tae 기술경영경제학회 2020 Journal of Technology Innovation Vol.28 No.4

본 연구는 환경역동성이 기업의 동적역량과 운영역량의 변화와 혁신성과에 미치는 영향을 실증하였다. 이를 위하여 기업역량을 동적역량과 운영역량의 계층적 구조로 정의하고 계량화를 위하여 각 역량의 개념과 정의를 정리하였다. 동적역량, 운영역량, 혁신성과 및 환경역동성에 대한 선행연구를 통해 5개의 연구가설을 설정하였고, 우리나라 제조기업 300개 기업의 표본을 대상으로 가설을 검증하였다. 그 결과, 동적역량은 운영역량에 정(+)의 영향을 미치며 운영역량도 혁신성과에 정(+)의 영향을 미치는 것으로 나타났다. 환경역동성이 높은 기업군은 운영역량이 급진적 혁신에 정(+)의 영향을 주며, 반대로 환경역동성이 낮은 기업군은 운영역량이 점진적 혁신에 정(+)의 영향을 주는 것으로 나타났다. 그러나 환경역동성은 동적역량이 운영역량에 미치는 영향에 조절효과가 유의하지 않은 것으로 나타났다. 본 연구는 동적역량과 운영역량을 프로세스로 구체화하여 기업의 동적역량 특성을 실증적으로 분석할 수 있는 기반을 마련하고, 환경변화가 기업역량과 혁신성과에 미치는 영향을 실증한 것에 의의가 있다. 또한 급변하는 환경 속에서 기업이 경쟁우위를 지속하기 위해서 어떻게 역량을 변화해야 하는지에 대한 시사점을 제시한 것에도 의의가 있다. This study empirically verified the effect of environmental dynamism on changes in the dynamic and operational capabilities of an enterprise and its innovation performance. With the aim of quantification, the concept and definition of each capability were defined as a hierarchical structure of dynamic and operational capabilities. Five research hypotheses were established through prior research on dynamic capabilities, operational capabilities, innovation performance, and environmental dynamism. For empirical analysis, the hypotheses were verified based on surveys from 300 Korean manufacturing companies. It was shown that Dynamic capabilities had a positive relationship with operational capabilities and operational capabilities had a positive relationship with innovation performance. And it was shown that operational capabilities had a positive relationship with radical innovation in business groups with high environmental dynamism while operating capabilities had a positive relationship with gradual innovation in business groups with low environmental dynamism. Also, the moderating effect of environmental dynamism was not significant in the relationship with dynamic capabilities on operational capabilities. This study is meaningful in that it lays the groundwork for empirically verifying the dynamic capabilities of an enterprise by embodying its dynamic capabilities and operational capabilities into processes, and verifies the effect of environmental change on its capabilities and innovation performance. And it has implications to suggest how an enterprise should transform its capabilities to sustain its competitive advantage in a rapidly changing environment.

Unlike research focused on existing technologies and individual errors to analyze the causes of incidents, this study approached them from an organization and culture. And this study is not a one way study but cyclical study what can track cause down using causal loop diagram methodology. Four diagnostic criteria for the negative state of the safety culture : secretive, blame, failure to learning, and incremental learning, combine literature study and expert opinion to derive 41 variables. Connecting these variable make 4 causal loop diagrams and total causal loop diagram. Case accumulation in secretive, accident report in blame, knowledge accumulation in failure to learning, near miss discovery in incremental learning are the main variables. Safety incident is the objective variable by classifying them into 4 stages in total loop, leading track as the most affect is case accumulation, and Step 4 as you can see accident report and near miss discovery are the result of tracking down the cause. This study can be used as a basis for improving the management priority and the system in incident prevention.
