  • Extant research on firm innovation productivity is limited in measuring the innovation productivity, in which they measured firm innovation productivity by using either inputs or outputs of innovation. The present study complemented the extant research by employing Data Envelopment Analysis (DEA) approach to measure firm innovation productivity. Furthermore, this paper examined the effects of firms' external knowledge search, as one of open innovation practices, on firm innovation productivity, for open innovation activities are regarded as an influencing factor on firm innovation productivity in the previous literatures. Using the data of the Korean Innovation Survey (KIS) of manufacturing industries conducted in 2008, this study developed hypotheses in which we considered not only two dimensions of external knowledge search (breadth and depth) but also two subtypes of external knowledge search (market-driven and science-driven). The results found that searching deeply and market-driven search are positively related to firm innovation productivity, but science-driven search is somewhat negatively related to firm innovation productivity. Furthermore, market-driven search can mitigate the negative effect of science-driven search on innovation productivity.

  • There have been many studies that open innovation activities have positive effects on firm performance. However, the previous studies have shown conflicting results, depending on the characteristics of companies or the timing of the product launch. This study empirically compares open innovation performance of first-mover companies and follower companies. The analyses are performed on the samples of the Korean Innovation Survey 2010 companies that explored external information and performed R&D cooperation. The results indicate that open innovation activities can have different effects depending on a company's status in the market. For the first-mover companies, the intensity of utilizing external information has greater impact on the firm's performance than the diversity of it. By contrast, for the follower companies, the diversity of utilizing external information has greater impact on the firm's performance than the intensity of it. In terms of R&D cooperation, the external cooperation is found not to have significant effects on a first-mover company's performance. However, external R&D cooperation of a follower company is showing positive impact on the firm's performance. The implication of the study is to analyze the firm's Open-Innovation performance by comparing first-mover companies with follower companies. Therefore, companies need to execute the Open-Innovation strategy by considering firm characteristics or the timing of the product launch.

  • As the external knowledge networks of firms have become more and more important to their product and service innovations, many global leading companies such as P & G, IBM, and Samsung Electronics have formulated and implemented their open innovation strategy. This study attempts to empirically analyze the effects of CEOs' supports for external knowledge networks, external knowledge network-oriented cultures and inter-organizational knowledge management systems as the major antecedents to external knowledge networks by using the data based on organizational members' perceptions about them. Based on 847 samples collected from employees in three companies in the medical, the construction and the IT service industries, this study performed a structural equation modeling (SEM) analysis about the effects of the antecedents to the external knowledge networks on product and service innovations through Partial Least Squares (PLS). The empirical findings of this study show that CEOs' supports for external knowledge network positively influence product and service innovations, partially mediated by external knowledge network-oriented cultures and inter-organizational knowledge management systems. And they also show that external knowledge network-oriented cultures and inter-organizational knowledge management systems have a positive effect on product and service innovations, respectively, partially mediated by external knowledge networks. With these new findings, academic and practical implications are discussed.

  • 이 논문은 중소기업을 대상으로 최근 기술혁신의 새로운 패러다임으로 대두되고 있는 개방형 혁신활동을 파악하는데 목적을 두었다. 특히 중소기업들이 기술혁신 과정에서 어떻게 외부와의 협력 네트워크가 구축되며, 실제로 어떤 단계에서 개방형 혁신활동이 이루어지는 가를 분석하였다. 외부와의 협력을 통해 기술개발을 경험한 3,400개 중소기업을 대상으로 개방형 혁신활동의 특성을 파악하였으며, 기술혁신과정의 어떤 단계에서 어떻게 개방형 혁신활동이 이루어지는 가를 구체적으로 파악하기 위하여 충북테크노파크에 입지한 14개 업체를 대상으로 하여 심층 인터뷰도 병행하였다. 연구 결과 기업 자체의 혁신역량이 부족한 중소기업의 경우 아이디어 단계 및 기술개발 단계에서 개방형 혁신활동을 통해 외부로부터 다양한 자원을 활용하며, 기업이 혁신적일수록 개방형 혁신활동을 활발하게 수행하고 있고, 이직이나 창업과 같은 노동시장의 유연성도 나타나고 있다.

  • ICT의 발달과 사물인터넷(IoT), 센서 네트워킹 기술 등이 차세대 산업경쟁력으로 자리잡아감에 따라 각 지자체의 스마트시티 도입이 가속화 되고 있다. 스마트시티를 운영하기 위해서는 도시통합운영센터가 요구되어 지고 그 기반에 통합 플랫폼이 존재한다. 기존 스마트시티 플랫폼은 주로 2차원 지도 기반으로 CCTV정보, ITS 교통카메라 정보 등을 이용하여 서비스를 제공하고 있다. 보다 고도화된 스마트시티 서비스 제공을 위해 3차원 지도 정보, 건물과 시설물 단위정보, 대민 서비스를 위한 공공데이터포탈과의 연계 등이 요구되고 있다. 본 논문에서는 스마트시티 통합 플랫폼과 관련된 국내외 관련 개발 현황을 살펴보고, 현재 개발 중에 있는 BIM/GIS 상호운용 플랫폼과 외부데이터 연계방안을 제시하였다. BIM/GIS 플랫폼은 지도기반 위치정보와 건물정보를 연계하여 실내외의 끊임없는 공간정보서비스를 가능하게 한다. 본 플랫폼에 적용된 외부데이터는 V-World, 서울시 열린 데이터, 건축데이터개방이며, BIM/GIS 플랫폼과 연계하여 국토계획 구역정보, 서울시 대기오염정보, 건축물대장정보 등을 확인하였다. 이를 통해 고도화된 신개념 스마트시티 서비스를 제공할 수 있는 BIM/GIS 통합플랫폼의 개발 방향에 대해 제시하고자 한다.

  • Open-source software development projects are well suited for exploring new ideas and acquiring knowledge from developers outside of the project. In this paper, we examine the impact of external developers on innovation in open-source software development from the perspective of organizational learning theory. We examine the roles of external and internal developers, who "explore" and "exploit," respectively, on the innovation performance of 17 691 open-source software development projects whose data is stored in the GitHub platform. The results indicate that a multifaceted strategy, in which the exploitation successfully supports the exploration, is most effective for their success. The results also indicate that the role of exploration decreases after the release of the software.

  • 본 연구에서는 외부유동현상 해석에 오픈 소스 기반의 전산유체역학 프로그램인 OpenFOAM의 적용가능성을 검토하였다. 이를 위해 초음속, 천음속, 아음속 유동 영역에서 각 부분에 대표적인 해석 케이스를 선정하고 OepnFOAM에서 제공하는 해석자를 사용하여 해석을 수행했으며 해석 결과를 실험 결과 및 타 전산유체역학코드와 비교하였다. 충격파가 발생하는 초음속과 천음속 영역에서 충격파 예측의 정확도를 확인할 수 있었으며 경계 조건에 따른 결과의 정확도를 비교하였다. 아음속 유동 영역에서는 큰 박리가 일어나는 해석 케이스를 선정하여 복잡한 유동장하에서 OpenFOAM의 해석 정확도를 확인하였다. 위의 연구 결과를 바탕으로 OpenFOAM의 활용가능성과 한계를 확인하였고 이를 바탕으로 향후 OpenFOAM을 기반으로 수행할 연구 내용을 제시하였다.

  • 30 kVA rotating-field type Super-Conducting Generator is built and tested with intensive FE(Finite Element) analysis. The generator is driven by VVVF inverter-fed induction motor. Open Circuit Characteristic(OCC) and Short Circuit Characteristic(SCC) are presented in this paper. Also, the test result under the light load(up to 3.6 kW) are given. From the design stage, 2-D FE analysis coupled with the external circuit has been performed. The external circuit includes the end winding resistance and reactance as well as two dampers. When compared with the test data, the FE analysis results show a very good agreement.

  • By interacting with external wireless sensors, smartphones can gather high-fidelity data on the surrounding environment to develop various environment-aware, personalized applications. In this work we introduce the sensor virtualization module (SVM), which virtualizes external sensors so that smartphone applications can easily utilize a large number of external sensing resources. Implemented on the Android platform, our SVM simplifies the management of external sensors by abstracting them as virtual sensors to provide the capability of resolving conflicting data requests from multiple applications and also allowing sensor data fusion for data from different sensors to create new customized sensors elements. We envision our SVM to open the possibilities of designing novel personalized smartphone applications.

  • Since the advent of Linked Data (LD) as a method for building webs of data, there have been many attempts to apply and implement LD in various settings. Efforts have been made to convert bibliographic data in libraries into Linked Data, thereby generating Library Linked Data (LLD). However, when memory institutions have tried to link their data with external sources based on principles suggested by Tim Berners-Lee, identifying appropriate vocabularies for use in describing their bibliographic data has proved challenging. The objective of this paper is to discuss the potential role of Linked Open Vocabularies (LOV) in providing better access to various open datasets and facilitating effective linking. The paper will also examine the ways in which memory institutions can utilize LOV to enhance the quality of LLD and LLD-based ontology design.
