오늘날 ICT는 타산업과의 융합을 통한 경제성장의 핵심수단 및 사회이슈를 해결할 도구로서 인식되고 있으나, 우리나라의 R&D 성과활용은 기술개발의 성공률에 비해 매우 낮은 수준이다. 이는 R&D의 공급자인 연구자 중심의 기획, 기술개발 추진이 주된 원인으로 지적되고 있다. 이에 따라, 수요자의 요구에 부합되는 시장성 있는 제품 서비스 구현이 R&D 추진의 중요한 요소로 대두되고 있으며, 기획에서부터 실사용자의 요구사항을 도출하고 기술개발과정에서 지속적으로 사용자의 피드백을 통해 수정해 나가는 리빙랩 방식의 적용이 절실히 필요한 상황이다. 그러나, 그동안 리빙랩 R&D는 사회문제해결형 또는 지역환경개선형에 집중해서 추진되어 왔다. 본 논문에서는 중소기업 R&D사업에의 리빙랩 도입 방안에 대해 검토해보고 이를 통해 기술개발 결과물의 사업화 가능성을 향상시키기 위한 효율적인 R&D 추진방안에 대해 제안하고자 한다.

In this study, we conducted a comparative analysis of R&D investment efficiency and operational efficiency of IT firms using Data Envelopment Analysis (DEA). We categorized thirteen sample firms into two groups-IT manufacturing and IT service-after an extensive literature review on IT industry classification. We adopted an output-oriented two-stage DEA model suggested by Banker et al. (1984) with total asset and R&D investment as input variables. Then, we constructed investment efficiency and operational efficiency by using Return on Equity (ROE) and Return on Asset (ROA) as intervening variables and operating income and Earnings Per Share (EPS) as output variables. The outcome of the analysis is summarized as follows. First of all, IT manufacturing firms were more efficient (57% on average) than IT service firms. To be specific, IT service firms showed decreasing returns to scale (DRS) with diseconomy of scale. In contrast, IT service firms showed higher operational efficiency (81.5% on average) than IT manufacturing firms. Also, we conducted a Mann-Whitney U test to compare the output of IT service firms and IT manufacturing firms. Lastly, we found a negative correlation ($R^2$ = -.754) between R&D investment efficiency and operational efficiency which infers the trade-off between two constructs

Personal broadcasting utilizing Vtuber, a virtual creator made of 2D or 3D avatars, has recently appeared and is growing in popularity. Vtuber is a virtual person who broadcasts on the Internet using 2D or 3D avatars with real-time motion capture and computer graphics technologies. While the personal broadcasting industry utilizing Vtuber is proliferating, related studies have mainly concentrated on technical issues. Therefore, in this study, the antecedent factors that form the technical characteristics and virtual creator characteristics of Vtuber personal broadcasting are derived using the Stimulus-Organism-Response (S-O-R) model. Then the effect of these factors on viewer pleasure and satisfaction, which lead to increased paid sponsorship is to be examined. Furthermore, we investigate how this influencing mechanism fluctuates based on the avatar type (2D vs. 3D). This study contributes to empirical examinations of viewers' paid sponsorship intention in Vtuber personal broadcasting through the S-O-R model. It also offers insights that technological or virtual creator characteristics could improve viewers' pleasure, satisfaction, and even paid sponsorship.

Owing to the development of computer technologies, to process data derived from various sensors is recently demanding. It is also increasing to demand the moving object based servies like the services of location based and mobile application services. That's why it is needed the processing of visualizing the services for education aspects. In this paper, we show the implemented results about $R^*$ tree algorithm to insert, delete and search a object in two dimension environment.

Since R&D (Research and Development) of small companies is becoming more and more important, and government R&D grants are still increasing. This study aims to investigate the factors influencing R&D performance of small companies and necessary capabilities of them. Based on empirical study of 3,636 small companies which participated and completed government R&D grant project, technology innovation capability and technology commercializing capability of small companies are positively related with organizational competences, with moderating effects of entrepreneurship. In addition, their R&D capabilities are not significantly related with R&D commercializing performance directly, but mediated with organizational competences. The results of study suggest implications of measuring the R&D performance of small companies and government support policy with the importance of organizational competences as an intermediate variable of R&D performances.

To improve research productivity, it is important to acquire up-to-date information quickly. To this end, researchers seek information resources through various channels and methods and utilize them in their research and development processes. The Korea Institute of Science and Technology Information (KISTI) has developed a platform for integrated scientific and scientific information service called ScienceOn to provide specialized information, infrastructure resources, industry and technology analysis resources in one place to support the research and information ecosystem. Through this process, accessibility and usability are enhanced through the connection and convergence of various information and services. In this study, we look at recent R&D trends in scientific technology academic information integration services and recommended packaging services that can be utilized in batches according to the purpose of use. We look forward to improving national R&D productivity by strengthening the linkage and convergence of scientific and technological information.

전통적 R&D 협업시스템은 불특정 사람들이 하나 이상의 프로젝트에서 독립적으로 일을 하는 협업 시스템으로 인터넷 기반의 소셜 소프트웨어(Social Software)나 위키(Wiki)와 같은 협업 툴을 통해 이루어진다. 하지만 협업적 작업을 위한 방법이 다양하고 외부에 많은 부분을 의존함으로써 프로젝트 참여자의 혼란이 가중된다. 따라서 본 논문에서는 이러한 문제점과 개방형 혁신(Open Innovation)을 위한 개방형 R&D 협업시스템을 설계하고 커뮤니티 도구와 시맨틱 전문가 검색 시스템 개발을 통해 R&D 협업시스템을 구현하여 시범 서비스를 수행한 사례를 제시한다. 개방형 R&D 협업 시스템은 개방형 혁신의 개념을 기반으로 사용자의 아이디어 수집을 위한 채널과 사용자의 행동 예측 및 정보 매칭 기술 등을 제공한다. 본 논문에서 제시하고 있는 R&D 협업시스템을 사용할 경우 미래 전 산업 연구 개발 분야에 큰 도움을 줄 수 있을 것으로 기대한다.
