Many scholars have addressed the technological convergence of small-medium sized firms in Korea and their impact on the economic growth of nation. Nevertheless, most studies have been investigated the relationship between entrepreneurship and venture creation, and a few studies have analyzed the innovation and technological convergence of SMEs. The purpose of this research is to gain industrial insight into the technological convergence and to suggest a dynamic growth policy for entrepreneurs of SMEs to improve their convergence performance based on IT and BT. Therefore, we intend to propose solutions to these key questions in convergence such as; what are the key patterns in the process of technological convergence of SMEs on IT and BT, and what kinds of strategy do their need? In order to answer these research questions, we adopt network analysis using patent citation information. Results of network analysis revealed that building ecosystem based on government and universities is one of the most important factors for the future growth of SMEs in Korea. Also, the fit between technological convergence direction of SMEs and division of convergence structure of government and universities will be positively associated with dynamic growth of SMEs in Korea. In conclusion, this research extends the current studies on important aspects of SMEs in the technological convergence process by proposing their growth in convergence process to a newly converging context, IT and BT, and shed light on the integrative perspectives of crucial roles of SMEs on innovation performance in the IT and BT technological convergence.

본고는 한국 에너지 기업의 기술수준을 세계 최고수준과 대비하고, 이러한 기술수준을 결정하는 요인들을 기술경제이론과 경영자원의존이론을 통해 살펴보았다. 한국 에너지기업의 세계최고수준 대비 기술수준은 기술경제적 요인인 규모의 경제효과와 전방기업과 후방기업간 협력적 관계 등에 의해 긍정적 영향을 받고 있는 것으로 분석되었다. 반면, 국내시장의 경쟁정도, 연구개발투자 비중, 연구개발인력 비중 등은 국내 에너지기업의 세계 최고수준 대비 제품기술수준에 영향을 미치치 못하고 있는 것으로 분석되고 있다. 이 분석에서 얻을 수 있는 정책적 시사점은 한국 에너지기업의 기술수준을 제고하기 위해서는 국내시장을 더욱 경쟁적으로 전환해야 하며, 연구개발투자와 연구개발인력 등을 확충하고 부가가치사슬 상에서 전방기업과 후방기업 간 공동발전을 촉진하는 정책을 추진할 필요가 있다는 것이다.

본 연구에서는 두 행위자 간 협력 및 경쟁이 모두 이루어지고 있는 다차원 관계에 대해 살펴본다. 다차원 관계는 두 상반된 상호작용 논리가 공존하고 있어 관계를 지속하는 것이 어렵지만, 기존 연구들은 주로 다차원 관계의 지속성에 대해 다루었다. 이에 본 연구에서는 다차원 관계가 협력 또는 경쟁의 일차원 관계로 전환되는데 영향을 미치는 요인에 대해 탐구한다. 특히 기술 의존성 측면에서 기술 거리와 기술 역량 차이가 작을수록 다차원 관계가 경쟁 관계로 전환될 것이라 주장하며, 기술 특성 측면에서 기술 변동성과 기술 정교성이 낮을수록 다차원 관계가 경쟁 관계로 전환될 것이라 주장한다. 본 연구는 LED 산업을 대상으로 양적 및 사례 연구를 통합적으로 수행한다. 연구 결과에 따르면 기술거리와 기술 역량 차이, 기술 변동성이 다차원 관계의 전환에 영향을 미치는 것으로 확인되었다. 이러한 연구 결과를 통해 다차원 관계가 예측하기 어려운 관계임에도 불구하고 기업이 관계기업의 행동을 예측할 수 있게 함으로써 대응 전략을 수립하는데 기여할 수 있다. 더불어 사례연구는 다차원 관계의 특성을 실제 현상에서 분명하게 보여준다는 점에서 해당 연구 주제에 대한 중요성을 강조하고 향후 연구에 있어 새로운 관점을 제시할 수 있다.

Negative bias temperature instability (NBTI) and positive bias temperature instability (PBTI) are critical circuit reliability issues in highly scaled CMOS technologies. In this paper, we analyze the impacts of NBTI and PBTI on SRAM $V_{MIN}$, and present a design solution for mitigating the impact of NBTI and PBTI on SRAM $V_{MIN}$. Two different types of SRAM $V_{MIN}$ (SNM-limited $V_{MIN}$ and time-limited $V_{MIN}$) are explained. Simulation results show that SNM-limited $V_{MIN}$ is more sensitive to NBTI while time-limited $V_{MIN}$ is more prone to suffer from PBTI effect. The proposed NBTI/PBTI-aware control of wordline pulse width and woldline voltage improves cell stability, and mitigates the $V_{MIN}$ degradation induced by NBTI/PBTI.

A simple mechanical model is proposed to demonstrate qualitatively the pancake progressive collapse of multi-storey structures. The impact between two collapsed storeys is simulated using a simple algorithm that builds on virtual mass-spring-damper system. To analyze various collapse modes, columns and beams are considered separately. Parametric studies show that the process of progressive collapse involves a large number of complex mechanisms. However, the proposed model provides a simple numerical tool to assess the overall behavior of collapse arising from a few initiating causes. Unique features, such as beam-to-beam connection failure criterion, and beam-to-column connection failure criterion are incorporated into the program. Besides, the criterion of local failure of structural members can also be easily incorporated into the proposed model.

본 연구는 2008년과 2010년 한국 제조업 부문 기술혁신조사 자료를 이용하여 비기술적 혁신 활동이 기업의 기술적 혁신 성과에 어떤 영향을 미치는지를 실증 분석하였다. 비기술적 혁신 활동을 조직혁신과 마케팅혁신으로 구분하고 각 혁신 활동이 혁신제품의 매출에 미치는 영향을 추정하였다. Tobit모형의 추정결과에 따르면 조직혁신과 마케팅혁신 모두 혁신제품의 매출 비중을 증가시키는 것으로 나타났다. 특히, 비기술적 혁신 활동은 급진적 혁신제품인 시장 최초의 혁신제품에 더 큰 영향을 미치는 것으로 추정되었다. 비기술적 혁신의 세부 유형별로 효과를 추정한 결과에 따르면 조직혁신 중에서는 업무수행방식의 변화만 유의한 효과를 보였으며 마케팅혁신은 제품디자인, 제품홍보, 가격전략 등이 혁신제품의 매출 비중을 높이는 것으로 나타났다.

This study aims to identify the causal relationship among public technology transfer, technological performance, and research and development (R&D) productivity. Using the impulse-response function(IRF) of a panel vector autoregressive model (panel VAR), this study suggests the results of how long the factors such as technological performance (patent), public technology transfer, and R&D productivity takes and lasts if a one-unit shock of standard deviation occurs. As a result, first, the increase of public technology transfer activities has no power to increase the technology performance but improve the R&D productivity. If the public institute increases its technology transfer activities by one unit, the R&D productivity will increase within five years. Second, the impact of increasing technological performance on improvement of public technology transfer and R&D productivity is an insignificant. Third, the effect of R&D productivity on the public technology transfer creates a substantial reaction after a current time. Considering the structural relationships among public technology transfer, technological performance, and R&D productivity, if policy makers intend to construct the active R&D circumstance, technology suppliers should be motivated to run the active R&D mechanism because they achieve gains.

The purpose of this paper is to understand the profiles of users and their motivations in sharing research articles on Twitter. The goal is to contribute to the understanding of Twitter as a new altmetric measure for assessing impact of research articles. In this paper, we extended the previous study of tweet motivations by finding out the profiles of twitter users. In particular, we examined six characteristics of users: gender, geographic distribution, academic, non-academic, individual, and organization. Out of several, we would like to highlight here three key findings. First, a great majority of users (86%) were from North America and Europe indicating the possibility that, if in general, tweets for research articles are mainly in English, Twitter as an alternative metric has a Western bias. Second, several previous altmetrics studies suggested that tweets, and altmetrics in general, do not indicate scholarly impact due to their low correlation with citation counts. This study provides further details in this aspect by revealing that most tweets (77%) were by individual users, 67% of whom were nonacademic. Therefore, tweets mostly reflect impact of research articles on the general public, rather than on academia. Finally, analysis from profiles and motivations showed that the majority of tweets (from 42% to 57%) in all user types highlighted the summary or findings of the article indicating that tweets are a new way of communicating research findings.

The Purpose of this study is to empirically examine the impact of various internal and external innovation activities of SMEs on their innovation performances in the field of electronics and communication industry. Drawing upon the literature review, internal and external innovation activities are defined and conceptualized, and independent, dependent and moderator variables are developed. We have used survey-based data for this study from the survey of technology innovation activities in manufacturing industry, which was conducted by the Science and Technology Policy Institute (STEPI) in 2010. The main result of this study shows that there were no significant differences in the impact of innovation activities on market performance according to the size of SMEs. On the other hands, we found that there were significant differences in the impact of innovation activities on technological innovation performance according to the size of SMEs. Therefore, in order to make high technological innovation performance, companies in the field of electronics and communication industry need to properly implement the internal and external innovation activities by considering their size.
