Many countries set growth engine technologies and industries for economic growth and job creation. Each country always wants to know their technological or industrial position in the world in these industries. This study aims at identifying the worldwide position of 19 growth engine industries defined in Korean government. The methods are quantitative by counting the number of startup companies in the world. The ORBIS database was used to extract the number. Therefore, this article may be the first research for the world appearance of growth engine industries and its comparison between world and G7, and between G7 countries. Also, this may be the first study using the ORBIS database on the analysis of certain technology industries. Further, we showed a method to identify world features of technology industries.

본 연구에서는 미국의 그린직업훈련체계 및 정책동향을 연방정부 및 주정부 차원에서 분석하고, 다양한 그린스킬 수요에 대응한 수준별 훈련프로그램체계와 관련 사례들을 조사하였다. 이러한 조사 분석에 기반 하여 우리나라 신성장동력분야의 향후 인력양성 정책방향을 다각도에서 제시하였다. 신성장동력분야는 우리나라의 경쟁력을 제고시킬 고부가가치 산업이지만, 첨단 기술력이 요구되고 투자 위험성이 크며 신속한 시장대응이 필요하기 때문에 적절한 인력공급체계를 갖추기 어려운 실정이다. 따라서 본 연구결과가 정부 인력양성정책의 문제점을 찾고 개선방안을 모색하는데 도움이 될 것으로 기대한다.

최근 기후변화 대응 및 경제위기 극복을 위하여 세계 각국은 녹색기술 육성과 환경규제 강화를 통한 자국의 신성장엔진 창출 및 경기부양에 모든 국력을 총동원하고 있다. 이에 한국 정부도 새로운 성장동력산업의 창출 및 육성을 위해 녹색기술사업과 관련하여 미래 유망신기술을 보유한 중소기업들을 대상으로 2009년부터 민관 공통으로 신성장동력펀드를 조성하여 운용하고 있다. 하지만, 현재 선성장동력펀드는 글로별 경제위기, 대규모 출자금액, 투자대상 기업 발굴의 어려움 등으로 민간자본 유치에 많은 어려움을 겪고 있으며, 이에 펀드 운영 방식의 변경이 불가피하다는 지적을 받고 있다. 본 연구에서는 신성장동력펀드의 지속적인 성장 및 확대 추진을 위해 해외펀드 조성 및 운영 사례를 기반으로 신성장동력산업의 지속적인 육성 및 지원을 위한 정부지자체협력 펀드, 정부금융기관협력 인큐베이터 펀드, 정부대기업-중소기업 상생협력 펀드의 운영 방안을 제안한다. 본 연구는 신성장동력산업의 육성이라는 전략적 정책을 지원함에 있어 다양한 펀드를 제안함으로써 정책의 실효성을 높이는데 의의를 가진다.

This paper examines the changing roles of ownership in the economic growth by using a panel data set of 30 provinces in China for the period (1999-2010). With the use of absolute and relative presence variables, this study shows that private enterprises have emerged as the engine of economic growth in China in the later period (2005-2010). The growing size and number of private enterprises are positively linked to growth. However, though foreign-invested enterprises have been acclaimed as the main contributors to economic growth in China, they have minimal effect on the economic growth in the later period. State-owned enterprises have a significant and negative effect on the economic growth in the later period. The results can be interpreted that the engine of growth in China has been changed over time from other ownerships to private ownership. Private companies have developed a lot in every respect and started to lead the economy for long-run growth. China initiated its economic growth by adopting foreign capital and it is still the top destination for foreign direct investment among developing countries. However, to sustain the growth over a long period, private sector should be of great importance and perform a key role in the view of catch-up economics.

Abstract MOCIE(Ministry of Commerce, Industry and Energy) handles 6 Projects for Intelligent Robot, whose budget is around 40 Million dollars per year. In this paper we have tried to analyze the state of robot technology of the projects. Each sub-projects has been divided according to the technological classification. Two major projects of Next Generation Growth Engine and 21C Frontier show different state each other. The former is focused on the product while the latter on the technology. Output of 21C Frontier should be linked to the Next Generation Growth Engine, otherwise, it will fail to advance. The project management handles only the quantitative performance such as business results, number of prototype, and number of patents and papers. Technological Capability is essential and it should be managed. This paper proposes efficient classification of robot technology and technology index.

The effects of swirl on early flame development and late combustion characteristic were investigated using a high speed single-shot visualized 51 engine. LDV measurements were performed to get better understanding of the flow field in this combustion chamber. Spark plugs were located at half radius (R/2) and central location of bore. High speed schlieren photographs at 20,000 frames/sec were taken to visualize the detailed formation and development of the flame kernel with cylinder pressure measurements. This study showed that high swirl gave favorable effects on combustion-related performances in terms of the maximum cylinder pressure and flame growth rate regardless of spark position. However, at R/2 ignition the low swirl shown desirable effects at low engine speed gave worse performances as engine speed increased than without swirl. There were distinct signs of slow-down in flame growth during the period when the flame front expanded from 2.5mm in radius until it reached 5.0mm apparently due to the presence of ground electrode. There seemed to be heat transfer effect on the flame expansion speed which was evidenced in high swirl case by the slowdown of the late flame front presumably caused by relatively large heat loss from burned gas to wall compared with low- or no-swirl cases.

For gas turbine engines, the safe life methodology has historically been used fur fatigue life management of failure critical engine components. The safe retirement limit is necessarily determined by a conservative life evaluation procedure, thereby many components which have a long residual life are discarded. The objective of this study is to introduce the damage tolerant design concept into the life management for aircraft engine component instead of conservative fatigue life methodology which has been used for both design and maintenance. Crack growth data were collected on a nickel base superalloy which have been subjected to combined static and cyclic loading at elevated temperatures. Stress analysis fur turbine disk was carried out. The program for computing creep-fatigue crack growth was developed. The residual lifes of turbine disk component under various temperatures and conditions using creep-fatigue crack growth data were estimated. As the result of analysis, it was confirmed that retirement fur cause concept was applicable to the evaluation of residual life of retired turbine disk which had been designed based on the conventional fatigue life methodology.

로켓 엔진을 설계추력보다 낮은 추력으로 운용하면 신뢰도가 증가하는 것으로 알려져 있다. 따라서 엔진을 디레이팅하여 증가하는 신뢰도가 엔진을 과설계하기 위해 증가된 개발비를 상쇄할 수 있다면 개발비를 최소화하기 위해 엔진의 과설계를 고려할 수 있다. 본 연구의 목적은 엔진 과설계와 디레이팅이 신뢰도 및 비용에 미치는 영향을 설명하는 모형을 개발하고자 하는 것이다. 타이탄 로켓 엔진의 운용추력수준 및 연소시험횟수에 따른 신뢰도 자료에 로지스틱 회귀모형을 적합하여 신뢰도 성장을 모형화하고 Transcost 비용모형을 이용하여 엔진을 10% 과설계 하면 신뢰도 요구값에 따라 엔진 개발비를 9%에서 23% 감소시킬 수 있음을 보였다. 또한 이러한 엔진 개발비의 감소는 엔진이 사용하는 연료에 따라 달라짐을 지적하였다.

This paper investigate the effects of the variations of engine operation condition in the flame kernel formation and developmnet . A model for calculating the initial kernel development in spark ignition engines is formualted. It considered input of electrical energy, combustion energy release and heat transfer to the spark plyg, cylinder head, and unburned mixture. The model also takes into accounts strain rate of initial kernel and residual gas fraction. The breakdown process and the subsequent electrical power input initially control the kernel growth while intermediate growth is mainly dominated by diffusion or conduction. Then, the flame propagates by the chemical energy and turbulent flame expansion. Flame kernel development also influenced by engine operating conditions, for example, EGR rate, air-fuel ration and intake manifold pressure.
