This study considered technology commercialization as a sort of external R&D of the licensee firm. Then, this study analyzed industrial characteristics of technology commercialization and interactions between internal R&D and technology commercialization from the licensee's viewpoint. Data from NTIS (National science and Technology Information Service) and KED (Korea Enterprise Database) were matched. 7,645 technology commercializations from 1,980 firms were extracted. Afterward, OLS and quantile regression were applied to the extracted data. The impact of technology commercialization on firm growth was concentrated to few high-tech and medium high-tech firms. Technology commercialization was effective in the growth in a year while internal R&D was effective in the growth in two years. The firm size was insiginificant variable. In analysis of 4 selected industries (automobile, electronics, semiconductor, chemistry), the impact was skewed among industries. Though the importance of technology commercialization is widely acknowledged, quantitative analyses like this study are uncommon. Therefore, this study can be useful for the tailored industry solutions for technology commercialization.

본 논문은 철강산업의 R&D 역량강화를 위해 IT 부문이 지원할 수 있는 정책을 모색하고 이에 대한 타당성을 검증한 사례연구이다. 기술추격형에서 기술선도형의 전환기에 놓여있는 국내 철강산업이 R&D 역량을 강화하기 위해서는 개별 철강사뿐만 아니라 대학, 연구소 등 외부와의 개방형 R&D 연계체제를 적극 추진해야 한다. 이러한 상황하에서 IT가 R&D 역량 강화를 효과적으로 지원하는 역할을 수행해야 한다. 본 연구에서는 이러한 목적을 갖는 IT 분야의 지원정책들을 개발하고 우선순위 분석, 수요분석 등을 통해 제안된 정책들의 타당성을 검토하며, Triple Helix관점에서 정부, 기업, 학계의 역할을 논의한다.

This study analyzed the impacts and factors of the government's local industry upbringing policy on business growth. We analyzed the effect of product innovation and technological innovation on business competence, external cooperation level, R&D investment, and corporate growth using PLS(Partial Least Squares) structural equation. The results show that management competence and external cooperation level have a significant effect on firm growth and that there is a moderating effect between beneficiaries and non-beneficiaries. Management competence affects product innovation. Product innovation was analyzed to have mediating effects on firm growth. Finally, the policy direction of increasing managerial capacity is presented, and the limitations and future research directions are suggested.

Technology-driven innovation and job-creation has each been the subject of much scholarly attention, but have largely been considered separately rather than in conjunction with each other. While the previous literature on economics pinpointed the macro effects on industry-level, this study explores the micro-level comparisons on innovation sources over the employment and financial performances. The PSM (propensity-score matching) analysis presents that firms, involved in an inward technology, tend to have higher employees with dominant technology capabilities than in-house R&D firms. The in-house R&D firms, on the contrary, have superior financial performances, suggesting that external technology commercialized firms suffer from low transformative efficiency. The mediation test analysis corroborates that the external technology-driven innovation induces more human resources in internalizing the exogenous technology. The positive relationship between R&D innovation and employment allow verification of the government's intervention in the promotion of technology commercialization in public sector. On the other hand, it also signals that the policy needs to enhance the recipient firms' commercializing capacity rather than a 'one-hit' transaction.

This paper deals with a case which is focused on the policy development connected with IT, and verify its validity to enhance R&D capability for Korean steel industry. Korean steel industry, which is at a turning point from technological catch-up to technological frontier, should go ahead with open R&D system to be able to connect with other steel companies, universities and laboratories for its capability buildup. To meet such a challenge, IT should act a critical part in R&D capability enhancement. In this study we discuss not only IT-related support policies and validity of proposed policies through priority analysis, but also the role of government, company and academia within the framework of Triple Helix.

자연재해 및 전력 시스템의 복잡성, 외부 노출 등으로 인해 전력 설비는 언제나 고장에 노출되어 있다. 전력회사는 전력의 안정성과 신뢰도 확보를 위해 끊임없이 노력하고 있지만 전력설비의 자그마한 이상에도 그 파급효과는 상당히 클 수 있다. 이에 선진 국가와 기업에서는 전력설비의 예방진단에 대한 많은 관심과 기술 개발이 이루어지고 있으며, 제품화되어 출시되고 있는 실정이다. (주)효성에서는 변압기 진단을 위한 센서 및 IED가 포함된 지능형 변압기(Intelligent Power Transformer)용 Local Unit을 개발하였다.

초음속 흡입구는 고속 비행에서 발생하는 충격파를 이용하여 제트엔진 내부에 유입되는 공기를 압축시키는 구조로써 주로 램제트와 스크램제트 엔진에 적용되어 연구개발이 진행되어 왔으며 현재는 미사일의 추진체 개발에도 응용되고 있다. 초음속 영역에서의 흡입구는 cone 모양의 스파이크 구조를 통해 경사충격파가 생성되어 외부에서의 공기압축을 먼저 거치게 된다. 본 연구에서는 EDISON CFD를 이용하여 외부압축 초음속 흡입구 주위의 공기유동을 해석하고 Cubbison, R.W.의 풍동실험 결과와 비교 분석하였다. 초음속 흡입구 주위의 유동을 2D 축대칭 압축성 유동으로 가정하고 EDISON CFD의 2D_Comp_P 솔버를 사용하여 수치해석을 수행하였다.

This study was conducted to verify the effect of chlorine dioxide ($ClO_2$) on odor reduction at a commercial swine facility consisting of a compost ficility. Compost facility in $NH_3$ concentration was around 550 ppm and less than 78 ppm before and after the $ClO_2$ spraying, respectively, which was over 86% reduction. There was no H2S detection. $NH_3$ concentration was around 420 ppm and less than 35 ppm before and after the $ClO_2$ spraying, respectively, which was over 83% reduction. $H_2S$ concentration was around 210 ppb and less than 32 ppb before and after the $ClO_2$ spraying, respectively, which was over 85% reduction. Hence, $ClO_2$ spraying at windowless barns was compost facility decreased malodor such as $NH_3$.

Obtaining external forced convection heat transfer from bubble boiling and validating it with experimental results using cryogenic liquids are suggested to derive total heat transfer coefficient with pool boiling condition in the case of coil type heat exchanger with a bundle of tubes and to overcome the limitation of using the empirical correlation. Experiment is conducted with pool boiling heat transfer of saturate liquid nitrogen with helical coil type heat exchanger using liquid oxygen as hot stream fluid. Experimentally measured heat transfer coefficient is well-agreed with the estimated curve considering nucleate boiling and forced convection induced by bubble rise.
