This paper examines the presence of network structures among convergence technologies focusing on national R&D projects performed by GRIs(Government-sponsored Research Institutes) in Korea. The dataset of convergence technology projects, which were conducted by 24 GRIs over 3 years (2011-2013), are analysed using the network analysis method. In this paper, a convergence technology project is defined as a project that consists of 2 or more then 2 technologies according to the intermediate classification of National Standard Classification of S&T. The research results confirm that convergence researches of government-sponsored research institutes are performed more actively than the entire convergence researches of national R&D projects. Furthermore, technological fields of GRIs' convergence projects are found to be much more varied. This paper also shows that in-house researches are more active than collaborative ones with external organizations. According to the network centrality analysis, it is identified that the network central characteristics of convergence technologies can be classified into internally oriented technologies and externally oriented technologies. Convergence technologies do not just mean simple mixture of different technologies. Therefore Korean government-sponsored research institutes should make more efforts to create convergence research areas which could generate new technologies and industries more effectively than simple multidisciplinary technology researches. From this perspective, some policy suggestions can be derived on the role of government-sponsored research institutes for activating convergence researches through the analysis of status of convergence researches and networks of institutions.

최근 들어 사회문제 해결형 과학기술혁신 활동이 활성화되고 있다. 과학기술정보통신부에서 추진하는 국민생활연구사업, 그리고 혁신본부에서 기획하고 있는 사회문제 해결을 위한 다부처 공동 기획사업 등이 추진되고 있다. 사회문제 해결형 과학기술혁신은 사회문제 해결을 최우선 목표로 삼고 있기 때문에 수월한 과학기술지식의 창출, 산업경쟁력 강화를 위한 혁신과는 목표와 추진체제가 다르다. 사회문제 해결형 과학기술혁신은 사회혁신과 과학기술을 결합하는 활동이라고 할 수 있다. 이렇게 새로운 유형의 혁신활동이 등장하면서 이를 바라보는 다양한 관점이 존재하고 있다. 본 발표에서는 각 논의들을 정리하고 향후 사회문제 해결형 과학기술혁신의 발전방향을 제시한다. 여기서는 크게 3가지 분류로 사회문제 해결형 혁신을 보는 관점을 정리한다. 첫 번째는 전문가 중심의 관점(Innovation for people)이다. 이는 전문가가 분석과 논의를 통해 사회문제를 정의하고 그 대안을 제시하는 접근이다. 많은 과학기술전문가들이 가지고 있는 틀로서 선형모델에 입각한 논의이다. 때문에 혁신의 선형모델이 가지고 있는 문제점, 피드백의 부족, 현장에 대한 이해 부족 등과 같은 단점이 있다. 두 번째는 시민사회 중심의 관점(Innovation by people)이다. 이는 현장의 문제 상황에 있는 시민들이 문제를 정의하고 혁신활동을 주도해야 한다는 관점이다. 이 관점은 일반 시민을 과학기술혁신의 주체로 호명하고 실질적인 문제 해결에 참여시키면서 주류 과학기술의 미흡한 현장 지역 지향성을 비판하고 있다. 그러나 혁신의 논의가 지역에 한정되면서 규모 확대의 어려움을 겪는 경우가 많다. 장기 지속성을 확보하는 데에도 난점이 있다. 세 번째는 전문가와 시민의 협업 관점(Innovation with people)이다. 이는 시민성과 전문성의 결합을 통해 민주주의를 고양하고, 현장 지식과 전문 지식의 융합을 지향하는 접근이다. 또 리빙랩과 같은 추진 체제를 적극적으로 활용한다. 그러나 전문가와 시민사회의 협업을 지원하는 인프라와 지원체제가 부족하면 여러 문제점이 발생할 수 있다. 본 연구에서는 이런 관점들의 한계를 극복하기 위해서 국지적 문제해결과 국가적 문제 해결의 연계, 실험의 중요성 강조, 전문가와 최종 사용자 및 시민의 실질적 협업을 위한 기반 구축, 시스템 전환 프레임의 도입을 정책 방향으로 제시했다.

Twitter users use 'Following', 'Retweet' and so on to find tweets that they are interested in. However, it is difficult for users to find tweets that are of interest to them on Twitter, which has more than 300 million users. In this paper, we developed a customized tweet recommendation system to resolve it. First, we gather current trends to collect tweets that are worth recommending to users and popular tweets that talk about trends. Later, to analyze users and recommend customized tweets, the users' tweets and the collected tweets are categorized. Finally, using Web service, we recommend tweets that match with user categorization and users whose interests match. Consequentially, we recommended 67.2% of proper tweet.
