  • 연구개발 지원산업은 연구개발 활동을 직·간접적으로 지원하는 산업을 의미한다. 이러한 산업에 대한 개념화는 연구개발 활동의 전문화(professionalization), 분업화(division of labor)가 진행되고 있음을 의미하는 동시에 연구개발체제의 유연성 제고 및 고도화, 효율화가 이루어지고 있음을 나타내고 있다. 우리의 경우 (과학기술혁신을 위한 특별법) 제 15조 등을 통하여 연구개발 지원사업에 대한 특별지원제도의 시행을 명시하고 있으나 현재까지 연구개발 지원사업자를 지정·육성하기 위한 기본현황 파악이나 분석이 이루어지지 않은 실정이다. 본고는 이러한 수요를 반영하여 국내에서의 연구개발 지원산업에 대한 수요를 중심으로 실태를 파악 ·분석하는 동시에 산업지원 육성방안을 제시하고 있다. 국내 연구개발 지원산업의 규모를 추정해 보면 97년 현재 약 3,000억원에서 4,000억원의 규모로 나타나며, 이중 기술정보서비스업이 약 27.0%, 연구장비 및 시험 ·평가 ·검색 ·분석업이 약 38.4%, 연구개발 설계·자문업 등 기타사업이 34.6% 로 나타나고 있다. 연구개발지원 기능은 시험·검사 기능과 기술정보제공 기능이 대부분을 차지하고 있고, 전자의 경우는 내부처리의 비중이 높고 후자의 경우 외부의 전문기관을 이용하는 비중이 높게 나타나고 있다. 특히 기업이 연구개발활동 수행시에 필요한 지원기능을 외부에 위탁할 경우에 느끼는 애로사항은 첫째, 외부 전문위탁기관의 부족 및 정보 미흡이 가장 크고, 둘째, 전문기관의 해외정보력·경쟁력 부족이 다음이며, 공공기관의 지원기능이 미흡하다는 애로사항에 대한 비중이 상대적으로 낮게 나타나고 있다. 연구개발 지원산업을 특별지원·육성하기 위한 기본관점은 특별법의 시행령을 구체적으로 실행하기 위한 시행계획의 수립과 연구개발 지원산업의 육성 시책의 추진 절차의 결정, 사업자 선정, 지원 사항 등으로 제시될 수 있다. 먼저, 기업 연구개발활동의 고도화·효율화를 위해 연구개발 및 기술개량에 필요한 업무 중 기술정보서비스와 연구시험·평가·검사·분석 그리고 중소기업 기술집약화를 지원하는 사업 등을 연구개발 지원산업으로 범위를 정할 필요성이 있다. 다음으로 연구개발 지원사업자를 별도로 선정·인정하는 방식으로 지원해야 할 필요성이 있다. 기존의 산업 지원방식으로는 연구개발 지원기능이 주된 활동으로 인정받을 수 없으므로 국내 연구개발 지원기능의 발전에 한계가 있다. 따라서 취약한 여건을 감안하여 연구개발 지원산업을 육성하지 않게 되면, 각 분야별로 민간사업자의 참여가 거의 이루어지지 않거나, 참여해도 연구개발 지원 기능의 발전보다는 기존의 사업이 주가 될 가능성이 크다. 연구개발 지원 사업자의 지정 지원방식과는 별도로 이루어질 수 있는 지원활동에 대한 지원은 기업회계처리상의 문제와 일관성이 있는 시책추진 및 효과를 기대하기 어렵기 때문에 사전에 동산업의 참여 자격·능력을 갖춘 사업자에 대해서는 제한없이 참여할 수 있도록 Positive System으로 추진해야 할 것이다. 그리고 연구개발 지원사업자에 대한 지원내용을 조세·금융 등 직접적 지원과 타 제도와의 연계지원 그리고 정부구매 등 시장지원 등이 아울러 다양하게 추진될 필요가 있다.

  • Scholarly monographs have been a main vehicle for knowledge representation and transfer as well as an important research outcome. University presses have long been considered as the last bastion for scholarly monographs that have low commercial prospect. Until now there has not been a systematic data analysis regarding scholarly monograph production by university presses in Korea. In this paper, we collected bibliographic records of university presses' monograph publications between 1950 and 2015 using the National Library of Korea's online catalog system. A total of 21,015 records were used in the analysis. In particular, for monographs published between 2001 and 2015, we categorized them into scholarly monographs and non-scholarly monographs. University presses' publishing showed sharp increase during the 1990's but is in decline after its peak in 2005. University presses seem to have engaged in publishing more non-scholarly monographs than scholarly monographs by a ratio of 6:4. Large university presses in size seem to produce higher proportions of scholarly monographs than smaller presses. In terms of authoring types, single authorship accounts for the highest proportion and on the increase. However, edited books are losing ground as translated books seem to hold steady. Monographs in social sciences have been published more frequently than any other subject areas as there seem to be significant discrepancies among subject areas in terms of the scholarly monograph proportion.

  • The purpose of this study was to investigate safety management awareness and behavioral investigation of radiation/radioactivity performance defenses of radiation workers' in medical institutions. Data collection consisted of 267 radiation workers working in medical institutions using structured questionnaires. As a result, it was analyzed that radiation safety management awareness and performance were high in 40s, 50s group and higher education group. The analysis according to the radiation safety management knowledge was analyzed that the "Know very well" group had higher scores on awareness and performance scores. The analysis according to the degree of safety management effort showed the high awareness scale and the performance scale in the group "Receiving various education or studying the safety management contents through book". The correlations between the sub-factors showed the highest positive correlation between perceived practician and personal perspective and perceived by patient and patient's caretaker perspective. Therefore, radiation safety management for workers, patients, and patient's caretaker should be conducted through continuous education of radiation safety management through various routes of radiation workers working at medical institutions.

  • 3D-Printing is one of the most innovative technologies that will be widely used in the 21st century. 3D-Printing also serves as an indispensable tool in STEAM education. In this article, we introduce what we have done in our mathematical modeling class in Uni. and recent R&E project under the support of Korean Foundation for the Advancement of Science and Creativity. We planned a model of STEAM education originating from our wish to make tangible models that use mathematical formulas to express the natural beauty of an object. We used a free, open-source software, Sage, to simulate these models online. Then, we created a program that generates a .STL file from these 3D images. This model can help students understand the natural beauty inherent in mathematics and use formulas and technology tools to simulate models in 3D. Finally, we were able to help students to create their own. STL files through a website we developed by adding Sage code into a Sage notebook. Then students can make and hold a 3D object of their very own. This process shows the possibility that mathematics, art and 3D-Printing can be effectively used to achieve the goals of STEAM education.
