This paper examines the intra-and inter-regional linkages of public research institutes (PRIs) with various innovation actors in Korea. In spite of the general consensus on the role of PRIs as innovation facilitators as well as creators, the attributes of regional spillover effect of knowledge created by PRIs have not been understood completely. Some argue that PRIs play pivotal role in encouraging intra-regional innovation networks through collective learning process. Others argue that PRIs are not necessarily related to intra-regional knowledge transfer, but play more important role in establishing national and international innovation linkages. This study attempts to figure out the current status of innovation linkages of Korean PRIs and to prove how the internal and external attributes of PRIs influence the development of spatial innovation linkages. Furthermore, it also tries to draw policy implication from empirical analysis results.

This research has been focused upon and analyzing Medison, once a leading New Technology-Based Firm (NTBF) in Korea with exceptionally advanced technology in 3D ultrasound diagnostic imaging devices (UDIDs) (armored with 23 subsidiaries at its peak expansion), from the perspective if Dynamic Firm Capability(DFC). The underlying hypothesis is that the various problems from its pointless pursuit of the business styles or precedents of the existing large firms might be traced to its specific characteristics as an NTBF, which should have more preferably been based upon the distinctive competences such as differentiated technologies, institutional linkages, organizational routines, and complementary assets, etc. In conclusion, for the NTBFs with different DFC domains from those of the large firms, the optimal external linkages and comprehensive integration efforts (Process) under their specific organizational characteristics and constraints (Path) are highly recommended for the continuous accumulation of their core capabilities based upon the technological assets (Position).

This paper proposes a tree-winding transformer protective relaying algorithm based on the ratio of increment of flux linkages (RIFL). The RIFL of the two windings is equal to the turns ratio for all operating conditions except an internal faults. For a single-phase transformer and three-phase transformer containing the wye-connected windings, the increments of flux linkages are calculated. for a three-phase transformer containing the delta-connected windings, the difference of the increments of flux linkages between the two phases are calculated using the line currents, because the winding currents are practically unavailable. Their ratios are compared with the turns ratio. The results of various tests show that the algorithm successfully discriminates internal faults from normal operation conditions such as magnetic inrush, overexcitation and external faults. The algorithm can not only detect internal winding faults, but reduce the operating time of a relay.

본 연구는 중소기업의 외부협력이 기업의 혁신, 매출성장과 수익증가, 그리고 생존에 미치는 영향을 다각적으로 분석하였다. 기업의 성과를 다양한 측면으로 나타내었을 뿐 아니라 외부연계는 직접협력과 비공식지식흐름의 두 가지 측면을 모두 고려하여 각 파트너 유형마다 기업의 성과에 어떠한 영향을 미치는 지 보다 세밀하게 검토하였다. 또한 Pavitt의 혁신체제 분류를 응용한 방식(Freel 2003; 홍장표 김은영 2009)을 도입하여 산업혁신체제별로 외부협력의 성과가 다르게 나타남을 보였다. 분석결과 기존의 국제연구(Belderbos et al. 2004)에서 관측되지 않았던 외부연계의 영향이 산업혁신체제별로 관측되었다. 대학 및 공공기관과의 협력 그리고 고객과의 협력이 매출증대에 도움이 되는 점이 확인되었으며 경쟁업체와의 협력은 생존측면에서 부정적인 면을 내포하고 있음이 탐지되었다. 본 연구의 결과는 과학기반혁신체제의 경우 외부협력이 효과가 있다는 것을 밝히고 있다. 또한 매출증대효과 및 생존율 향상 효과가 있는 대학 및 공공기관 협력을 통해 관계위험이 존재하는 경쟁업체와의 협력을 보완하는 방식이 효과적일 수 있다는 시사점이 도출되었다.

This paper uses social network theory and the internationalization process model (IPM) to determine how external network linkages influence the location choices of multinational enterprise from emerging economies (EMNEs); specifically, whether past alliance experience influences location choices and its impact on the subsequent entry of MNEs from emerging economies. This paper applies survival analysis using initial and secondary investments from 2,000 Chinese A-share listed companies that entered 90 countries between 1997 and 2018 to analyze both the initial and subsequent entries of Chinese outward foreign direct investments (OFDIs) in major host countries. The findings indicate that an MNE's previous experience with a company from a particular country will increase the likelihood of an initial investment in that country. Previous alliance experience may accelerate the foreign investment process of EMNE and stimulate firms making a commitment to a position in a foreign network, regardless of cultural distance and stage of internationalization. Alliance before initial investment may increase the likelihood and speed of entering a host country as wholly owned subsidiaries and that network linkages not only significantly influence the internationalization process of small and medium-sized enterprises, as indicated by the IPM, but also that of large listed firms.

This study empirically examined the relationships between the growth stage of ventures and their business characteristics such as KSFs, environmental attributes, CEO roles, and utilization of external resources, based on data from 2,515 Korean ventures. ANOVA results of this study revealed that 1) Key success factors appeared different across the different growth stage of Korean ventures. Financial resources were most critical in the early stage of growth, while the foreign technology licensing appeared to be most important for the success of ventures at later growth stage; 2) As the Korean ventures grew, their environments became more dynamic and hostile; 3) Strategic and external activity roles of top management were critical in younger ventures, while roles for marketing and production were important in older ventures; and 4) Utilization of external resources were more frequent at the later stage of ventures than at the early stage of growth. Based on the research, this study offered several managerial, theoretical, and policy implications.

This paper explores the relationships between technological acquisition strategies of small firms and innovation in the Korean Electronics industry. Its thesis is that small firms' technology strategies and their effects on the rate of innovation differ according to the new and traditional technology settings. A primary finding of this study is that in-house R & D and technical linkages with buyers and suppliers have stronger effects on the radical innovation in the new technology setting rather than in the traditional technology setting. The findings of the study provides insight for interpreting inconsistent results of recent research for the importance of external linkages to innovation. They also suggest some implications of small firms' strategies and public policies for accelerating technological innovation.

Studies on innovation point towards the need for both in-house research and development (R&D) capabilities along with collaborations with external organisations or linkages with other firms, universities and research institutes. The argument is that innovation is not just a firm specific factor but requires support from several other factors which in turn involves developing linkages with various actors/institutions as sources of resources and/or knowledge for innovation. This paper presents findings from an exploratory study about the Malaysian biofuel sector as an innovation system. Instead of using the neo-classical approach and proposing policy interventions based on traditional market failure rationale (Bergek et al., 2008a), the functional analysis of the technological innovation systems (TIS) approach is used to analyse the biofuel sector in Malaysia to help reveal the strengths and weaknesses in terms of its fulfillment of seven critical functions which are necessary for the generation and commercialization of a product. In addition an attempt is made to reveal the inducement and blocking mechanisms affecting the Malaysian biofuel TIS and the seeking of improved poor functionality. These functional aspects of the Malaysian biofuel sector are analysed in different phases of its development to gain an understanding of the different institutions and their functions at different phases of the development of the innovation system.

본 연구는 기업의 외부통제에 관한 개념적인 논의와 함께, 한국의 제조업에서 80년 대 중반 이후(1986-1992)에 나타난 통제의 공간적 변화를 경험적으로 조사하였다. 15개의 지역 사이에 다입지 기업의 소유연계에 대한 자료가 외부통제의 대체척도로 이용되었다. 이 자료를 근거로 생산과정의 특성에 따른 세가지 유형의 제조업 부문별로 통제의 변화를 지도 화하여 분석하였다. 전반적인 외부통제의 지리적 특징은 서울이 탁월한 통제의 중심지로서, 서울의 영향력은 수도권과 동남권의 산업발달 지역에 집중되었지만, 최근에 그 영향력은 산 업이 낙후된 지역까지 확산되어 전국적이다. 또한 새로운 통제의 중심지로 수도권과 동남권 의 중심인 대도시가 서서히 부각되고 있다. 이러한 특징에도 불구하고, 제조업 유형별로 상 이한 외부통제의 공간적 패턴은 생산의 조직구조가 생산과정에서 필요로 하는 자본과 노동 은 물론 부문이 처한 외부환경에 따라 변화됨을 보여준다. 이러한 결과는 상이한 생산과정 을 채택하는 다입지 기업의 공간적 영향에 차별적 분석을 요구한다.
