이 논문의 목적은 기술혁신의 특징과 그에 따른 파급효과를 알아보는 것이다. 기존의 기술혁신에 대한 연구에서 기술혁신의 특징을 정의하고 분류하는 연구가 많이 진행되었다. 이런 다양한 기술혁신의 특징들 중에서 기술혁신에 대한 의사결정에 영향을 미치는 위험부담(Risk)과 관계되는 특징들을 이 연구에서 사용하였다. 첫 번째는 산업의 관점에서 본 위험부담에 관계되는 특징으로, 과거에 개발했던 기술혁신과의 연관성을 나타내는 산업기술연관성이다. 두 번째는 기업의 관점에서 본 위험부담에 관계되는 특징으로, 기업의 범위에서 과거에 개발했던 분야의 기술혁신과의 연관성을 나타내는 기업기술연관성이다. 세 번째는 시간의 관점에서 본 위험부담에 관계되는 특징으로, 기술혁신이 개발 당시 얼마나 최근의 연구인지 알려주는 최신성(Recency)이다. 2000년도 미국 반도체 산업의 특허자료(USPTO)로 분석한 결과, 기술혁신의 특징들 중 산업기술연관성과 기업기술연관성이 기술의 파급효과에 긍정적인 영향을 미친다는 것을 발견하였다. 즉, 산업의 관점과 기업의 관점 모두 위험부담이 적은 기술혁신이 더 큰 파급효과를 가지고, 시간의 관점에서 본 기술혁신의 최신성은 기술의 파급효과에 중요한 요인이 아니라는 것을 알 수 있었다. 즉, 성숙기 시장에서는 기존의 기술혁신을 향상시키는 혁신과 자기기업기술을 많이 이용한 기술혁신이 큰 파급효과를 가진다는 것을 알 수 있었다.

For the domestic digital contents, a proactive cooperation system or framework between the government, the businesses and research institutions, which would allow for free flow of interaction among these players, can play that role. We have proposed and realized the Dynamic Coordinating Framework(DCF) to bridge these gaps among the major players in the industry. The the Dynamic Coordinating Framework rests on the following major functions. The first major function of the DCF is to decipher any ambiguity that may be embedded in external inputs by stratified role and bias. The second function is to create cooperative groups that will deal with the ambiguities based on its consequent situation. The third is a feedback function that will draw out a new cooperative way by re-feeding the capacities and the conflicts that stem from the existing organizations and strategies into cooperation and adjustment process. Our DCF has compared and evaluated with England and Australia digital content industry models under AHP(Analytic Hierarchy Process) method. DCF has turned out to be well designed and have strong points based on OECD innovation and cooperation criteria.

The authors of the study highlight the conceptual foundations of the investment mechanism of innovation of enterprises in the context of strategic development. Such indicators of investment attraction for the enterprise as investment attractiveness, investment activity of the enterprise, critical mass of investments, minimum sufficiency of investments and others are singled out. It is proved that the balance of investment resources is facilitated by the action of the investment mechanism of innovation activity at the enterprise in the context of achievements of strategic development tasks. Investment processes and their intensification have an impact on the expansion of production capacity of economic entities in strategic development and on improving the efficiency of existing capacities. The investment mechanism of innovative activity at the enterprise in the context of achievement of tasks of strategic development contains system of complex actions which provides: definition of the clear purpose and tasks for the mechanism and achievement of the purposes of the enterprise; assessment of the investment potential of the enterprise; definition of tasks of innovative development of enterprises and investment resources necessary for this purpose, etc. The tasks of the investment mechanism of innovative activity at the enterprise in the context of achievements of tasks of strategic development and its economic, organizational and information components are singled out, as well as levers of influence and regulators of the investment mechanism of innovation in the enterprise.

Tower structures have been widely used in communication and transmission engineering. The failure of joints is the leading cause of structure failure, which make it play a crucial role in tower structure engineering. In this study, the aluminum alloy three tube tower structure is taken as the prototype, and the middle joint of the tower was selected as the research object. Three different stainless steel-aluminum alloy composite joints (SACJs), denoted by TA, TB and TC, were designed. Finite element (FE) modeling analysis was used to compare and determine the TC joint as the best solution. Detail requirements of fasteners in the TC stainless steel-aluminum alloy composite joint (TC-SACJ) were designed and verified. In order to systematically and comprehensively study the mechanical properties of TC-SACJ under multi-directional loading conditions, the full-scale experiments and FE simulation models were all performed for mechanical response analysis. The failure modes, load-carrying capacities, and axial load versus displacement/stain testing curves of all full-scale specimens under tension/compression loading conditions were obtained. The results show that the maximum vertical displacement of aluminum alloy tube is 26.9mm, and the maximum lateral displacement of TC-SACJs is 1.0 mm. In general, the TC-SACJs are in an elastic state under the design load, which meet the design requirements and has a good safety reserve. This work can provide references for the design and engineering application of aluminum alloy tower structures.

Si-carbon composites as anode materials for lithium rechargeable batteries were prepared simply by mixing Si nanoparticles with carbon black and/or graphite through a solution process. Si nanoparticles were well dispersed and deposited on the surface of the carbon in a tetrahydrofuran solution. Si-carbon composites showed more than 700 mAh/g of initial capacity under less than 20% loading of Si nanoparticle in the composites. While the electrode with only Si nanoparticles showed fast capacity fading during continuous cycling, Si-carbon composite electrodes showed higher capacities. The cycle performances of Si nanoparticles in composites containing graphite were improved due to the role of the graphite as a matrix.

The purpose of this study was to establish which factors were considered when fashion companies discussed the intention of employing the internet in various capacities. A total of 228 candidates were surveyed between 17-11-07 and 17-01-08. The collected data was used to conduct various descriptive and comparative analyses. Firstly, environmental factors considered important were internal pressure, external pressure and uncertainty of the market. Organizational factors considered important were support of the chief executive officer, capacity of the organization and future directivity. Profit factors considered important were elevation of the business, customer relationship management, advantage of the internet and reduction of expenses. Prohibitive factors considered important were miscellaneous expenses, secession of the customer, internal opposition of the organization and convertible expenses. Secondly, fashion companies regarded internal pressure, external pressure, support of the chief executive officer, capacity of the organization, future directivity, elevation of the business, customer relationship management, advantage of the internet and miscellaneous expenses as important when discussing the introduction of the internet.

신활력사업은 전국 234개 지방자치단체 가운데 인구, 재정, 산업 등의 지표를 바탕으로 낙후된 하위 30%에 해당하는 70개 시 군의 혁신역량을 제고하고 지역에 새로운 활력을 불어넣는다는 취지로 시작된 새로운 낙후지역발전정책이다. 그러나 신활력사업계획의 수립과정은 지역혁신에 기초한 지역발전 논리나 거버넌스 구축 과정을 충실히 반영하지 못한 것으로 평가된다. 신활력사업은 그 취지 상 지역 스스로 지역의 주도하에 숙의(熟議) 민주주의(deliberative democracy)를 통해 사업을 추진해야만 한다. 그러나 실제 추진 과정에서 진정한 의미의 자율적 지방화의 성격을 띠기보다는, 지역을 믿지 못하고 성과에 집착하는 조급한 중앙정부에 의한 타율적 지방화의 모습이 노정되고 있다. 이러한 점에서 신활력사업계획 수립 및 추진과정은 능동적으로 지방화를 하기 보다는 수동적으로 지방화를 당하는 측면이 적지 않다고 평가된다. 본 연구는 이러한 문제의식 하에 신활력사업계획의 수립 및 추진과정을 비판적으로 평가하고, 이를 토대로 앞으로의 개선 방향을 제시한다.
