창업보육센터 매니저의 보유 역량과 필요 역량의 비교 연구

백광현(Baik Kwang-Hyun),이상호(Lee Sang-Ho) 한국산학기술학회 2011 한국산학기술학회논문지 Vol.12 No.5

창업보육센터(BI: Business Incubator)와 관련된 국내외 주요 연구들은 창업보육센터의 실태 조사를 통한 활 성화 및 발전 방안과 BI의 성공요인으로서 BI매니저의 역량을 다루고 있다. BI매니저의 역할과 자질에 대한 탐색적/ 학술적 논의가 이루어지고 있으나, BI매니저의 보유 역량과 필요 역량을 비교 분석한 연구는 제한적이다. 본 연구는 BI매니저의 보유 역량과 입주기업이 요구하는 필요 역량을 비교 분석하여, BI매니저의 부족한 역량을 집중적으로 강 화하기 위한 운영 정책과 교육 프로그램의 주제를 제시한다. 역량 강화가 주로 필요한 영역은 자금조달 지원과 마케팅 지원이었다. Managers in Business Incubator(BI) perform an important role to success of BI, but researches about what area of capability need to improve are limited. This study investigates the perceived gap between current capability and required capability of BI managers from BI managers’ and CEOs’ perspectives with a survey method. From the BI managers’ perspective, improvement of most capabilities, such as financing support, R&D support and understanding of patents, and understanding of business of firms in BI, is needed. From CEOs’ perspective, improvement of capability in financing and marketing support is needed.

국내 창업활성화를 위한 창업지도사 자격증 도입 방안 연구

백광현(Baik, Kwang-Hyun) 한국경영교육학회 2009 경영교육연구 Vol.53 No.-

향후 창업보육사업이 좀 더 성공적으로 진행되어 국가경제발전의 원동력이 되기 위해서는 무엇보다 창업보육매니저의 자격 및 역할을 획기적으로 제고시키는 것이 절대적으로 필요하다. 그동안 창업보육매니저를 대상으로 실시해온 교육이 매니저들의 역량을 향상시켜온 것은 사실이나, 전문적이고 실무적인 교육이라기보다는 획일적이고 총론적인 교육과정에 치우쳐 매니저의 직무역량 제고에는 한계가 있었다고 할 수 있다. 이를 위해 창업보육매니저로서의 역량을 체계적으로 향상시킬 수 있도록 실무위주로 실시함과 아울러, 매니저를 위한 국가자격 창업지도사 제도를 순차적으로 도입하는 것을 제안한다. 본 연구는 창업보육매니저에 대한 기존의 문헌 및 선행연구 결과를 검토함으로써 창업보육센터에서 차지하는 매니저의 비중과 중요성을 인식하고 창업보육매니저를 위한 창업지도사 국가자격증 제도의 성공적인 정착을 통해 매니저의 전문성 및 경쟁력을 강화함으로써 창업보육센터 입주기업의 창업성공률을 제고할 수 있는 기반을 마련하고자 한다. It is absolutely required to remarkably enhance the qualification and role of the business incubating managers for the successful business incubation that contributes to the growth of the national economy. Although the educations to the business incubating managers so long do improve the their capability, it is also true that the contents of education are rather too general than professionally specific, which limits the production of high-quality business incubating managers. Hence we propose that the major contents of education be changed to more practical business affairs to systematically enhance the capability of the business incubating managers and the national certification of the business incubating instructors be introduced sequentially. In this work, the importance of the business incubating managers in business incubator has been reassured through the investigation of the previous researches. The capability of the business incubating manager is often critical to determine the success of the incubated companies. Therefore it is necessary that the professionality and competitiveness of the business incubating managers are qualified. It is expected that the introduction of the national certification of the business incubating instructors helps the qualification of the business incubating managers and significantly enhance the number of the successful settlement of the companies in the business incubator.

백광현(Baik Kwang-Hyun),김경수(Kim, Kyung-Soo) 한국산학기술학회 2007 한국산학기술학회논문지 Vol.8 No.6

본 연구에서는 차세대 고부가가치 지식산업이 될 u-러닝에 대한 개념, 그리고 국내·외 u-러닝 시장 동향 및 u-러닝 산업추진상의 문제점을 살펴보았다. 이와 더불어 국내 u-러닝 산업의 SWOT 분석을 통해 국내 산업 경쟁력 확보하기 위한 정책과제 및 추진방향을 도출하였다. The u-Leaning just begins to emerge as the next-generation knowledge-based business. Since it has a great potential to become a high value-added industry, there is much attention paid in this field. In this work, we first summarized the concept of the u-Learning where the architecture of various u-Learning areas has been identified. Then we investigated the current status and problems of the u-Learning industry. Through the SWOT analysis, we have extracted the political strategies that will be essential for the rapid industrialization of u-Learning which will, in turn, contribute much to enhance the competitiveness of national economy.

산업연관분석을 이용한 국내 유비쿼터스 산업의 경제적 파급효과에 관한 연구

백광현(Baik Kwang-Hyun),석영기(Suk Young-Ki) 한국산학기술학회 2006 한국산학기술학회논문지 Vol.7 No.3

본 연구의 목적은 u-Korea 추진계획 수립을 위해 국내 유비쿼터스 산업의 경제적 파급효과를 분석하는데 있다. IT의 혁신적 발전에 따라 유비쿼터스 산업은 국가경제에서 차지하는 비중도 크게 증가하고 있고 그 역할의 중요성이 보다 더해가고 있다. 따라서 산업연관분석 모형을 통해 유비쿼터스 산업이 국민경제에서 차지하는 역할을 진단하고 이에 대응하는 산업 정책을 수립하는데 도움을 주고자 한다. 특히 본 연구에서는 2000년 한국은행의 산업연관표를 이용하여 유비쿼터스 산업의 시장 가치를 중심에 놓고 이를 외생화하여 분석 및 해석하는 접근방법을 취함으로써 유비쿼터스 산업 자체뿐만 아니라 타 산업의 경제적 파급효과도 논의를 집중시켰다. 보다 구체적으로는 산업분류 부문별로 그리고 전체 유비쿼터스 산업의 생산유발효과, 부가가치유발효과, 수출 및 수입유발효과, 고용유발효과 등이 2005년부터 2010년까지 240조원에 이를 것으로 연구결과는 제시하고 있다. In this paper, we investigate the national effects of the ubiquitous industry(UI) for a u-Korea(ubiquitous Korea) project. As the UI has now been playing the more and more important role in Korean economy, it will be very appropriate to provide the policy makers with the accurate and reliable implications regarding the role of UI in the national economy. This paper applies the interindustry analysis to examine the impact of UI under the unique situation of Korea. To do this, we use the Input-Output Table published by the Bank of Korea in 2000. Our results shows that the economic effects of UI on the production-inducing, value added-inducing, export & import-inducing and employment-inducing in Korea will approximately be 240 trillion won from 2005 through 2010.

By using a simple solution based method, gold nanonetworks which are randomly distributed gold nanowires arrays were synthesized. After APTMS (3-aminopropyltrimethoxysilane) treatment, adhesion of gold nanonetworks with 10-15 nm diameters to the substrate was greatly enhanced. Density of gold nanonetworks increased with number of coating, and uniformly coated nanonetworks were connected physically and electrically. Gold nanonetworks deposited on the flexible polyimide substrate shows constant electrical conductivity for physical bending of the substrate.

However, no significant difference was found in plasma norepinephrine between training antral non-training groups. 10.There were no differences in epinephrine and norepinephrine after a brief period of maximal exercise load for active(271.48±72.16pg/ml, 297.96± 101.21pg/ml) and passive recovery(271.70±81.28pg/ml, 311.69±109.38pg/ml) respectively. 11.No relationships could be observed between epinephrine and norepinephrine concentrations and maximal capillary blood locate values after a brief period of maximal exercise load. In conclusion, blood lactate concentrations were significantly low in training group after maximal exercise load compare to non-training group. Recovery of blood lactate concentration after exercise was also faster in training group compared to non-training group. Especially, active recovery at rest was found to be more effective blood lactate disappearance. There were no changes in catecholamine after a brief period of maximal exercise load. Catecholamine concentrations were not affected by recovery method and it did not show to be influenced by blood lactate concentrations.
