중소기업이 글로벌 경쟁력을 확보하고 장기적인 경쟁우위를 확보하기 최선의 전략은 기업자원 및 역량을 활용한 혁신을 통해 급변하는 환경변화에 적응하는 것이다. 따라서 본 연구에서는 제조업에 속하는 중기업을 대상으로 산업·조직특성 및 기업혁신과 기업성과간의 직접적인 연관관계뿐만 아니라 산업환경과 조직특성인 지식의 수준이 기업혁신과 성과간의 관계에 미치는 간접적인 영향을 분석하고자 횡단면분석을 수행하였다. 연구결과, 중기업의 지식자산과 교육투자, 산업의 역동성은 기업혁신과 정의 관련성이 있는 것으로 나타났는데, 이는 중기업이 연구개발 집약적인 산업에 속하고, 석사이상의 고급인력 보유 비율이 높고, 교육에 대한 투자가 많을수록 혁신활동비율이 더 커진다는 것을 의미한다. 그러나 기업혁신과 성과간의 관계에 관한 분석에서는 기업혁신 뿐만 아니라 산업역동성 및 기업의 지식수준과 혁신간의 상호작용 모두 기업성과에 유의한 관련성이 없는 것으로 나타났으며, 고기술과 저기술 기업으로 나눈 추가 분석에서도 유사한 결과가 나타났다. 이러한 결과는 단기적으로 기업의 지식자산 및 교육에 대한 투자가 혁신 및 기업성과간의 관계에 유의한 영향을 미치지 않으며 산업환경에 따라 뚜렷한 차이가 없음을 의미한다.

This paper examined the effect of innovation networks comprising research and development (R&D) collaboration on innovation performance of Korean pharmaceutical firms. As co-assigned patents and co-affiliated publications are common technical outcomes of successful R&D collaboration in the pharmaceutical industry, social network analysis technique was applied for analyzing innovation networks through patent and publication data. Results of Social network analysis indicated that a small set of highly innovative firms in the Korean pharmaceutical industry were actively involved in patenting and publishing. And the analysis of structural equation model found the followings: (1) R&D intensity significantly affected patenting, publication and new drug development, (2) the activity of patenting and publishing was positively related with the innovation performance measured by new drug development, and (3) R&D collaboration in terms of degree centrality of co-patent network played significant moderating roles on the relationships among R&D intensity, patenting, and new drug development. These findings are expected to be helpful to researchers as well as policy-makers to devise innovation-promoting policies in the Korean pharmaceutical industry. Discussions and limitations of the study are provided in the last part.

With the increase of global competition and the reduction of the lifecycle of business process, most leading companies begin to adopt BPO(Business Process Outsourcing), by outsourcing the whole or part of their business process to external service providers and focusing on their core capability, in order to enhance their core competency, In adopting BPO, it is an important decision-making issue that which part of process should be outsourced. So identifying core/non-core process among the business processes is a prerequisite for managing corporate capability and performance of outsourcing. In this study, by focusing on knowledge intensity and degree of informatization of the business process that are important factors in adopting BPO, we have analyzed the current status of BPO adoption of domestic firms and proposed several guidelines for adopting BPO.

The exit surface of a lens is designed using a three-dimensional free-form expression in order to easily modify a curved surface. This enables the design of numerical values and mathematical things using three-dimensional free-form expression, and enhances precision because it can be fine-tuned via numerical control. The standard of "Classification of Luminaire Light Distribution" for outdoor lighting fixtures by IESNA is adopted in order to examine the correlation between three-dimensional free-form surface expression and lighting performance. The variation of light distribution type and range is analyzed using the values of maximum light intensity and 50% light intensity. The actual tolerance occurs owing to parameters such as the thickness of the lens, the distance between LEDs, and the movement of the center of the incident surface; the effects of changes in these parameters on the performance are compared and analyzed.

Knowledge sharing, as well as knowledge creation, is the basis for an organization to maintain its competitive advantage. Organizations trying to use knowledge resources for strategic purposes or pursuing knowledge management are now paying more attention to methods to facilitate knowledge sharing. This study aims to find out the answers to the questions below. (1) Which relational or structural factors influence the intentions to share knowledge among groups? (2) Does the intension to share knowledge among groups really influence the knowledge sharing behavior? (3) What are the roles of accessibility on the relationship between intention to share knowledge and behavior of knowledge sharing? (4) Does the behavior of knowledge sharing really improve the effectiveness of knowledge sharing among groups? Findings of this study are summarized as follows. First, the positive relations of the relational and structural factors with the intention to share knowledge among groups are found. However, crisis intensity was found to have no meaningful influence on the intention to share knowledge among groups. After all we could see through additional analysis that it is in curvilinear relation, not linear relation. Second, we examined relation of the intention to share knowledge with the behavior of knowledge sharing among groups. Multiple regression analysis showed that intention to share knowledge among groups had a statistically significant influence on the behavior of knowledge sharing among groups. Third, the moderating effect of accessibility on the relation between the intention to share knowledge and the behavior of knowledge sharing was found to be statistically significant. Fourth, the relation between behavior of knowledge sharing and the effectiveness among groups was found to be statistically significant, but in a negative direction. The findings imply that the quantity of knowledge sharing does not always lead to the effectiveness of knowledge sharing.

Based on the usage levels of target costing systems(TCS) and information technology (IT) infrastructure, this study aims to develop a framework useful for classifying four types of knowledge management(KM) strategies in manufacturing firms: process-oriented, product-oriented, mixed and negative. We adopted a multi-methodological approach by mixing both qualitative and quantitative methods. Before developing a framework, through a case study of the H Motor Company in Korea, this paper investigated and showed the functions of TCS in the management of tacit knowledge. The results from the case study indicated that with the use of TCS, a firm can create, transfer, and share diverse kinds of tacit knowledge among employees for the facilitation of process innovation. We also empirically confirmed the four types of KM strategies, and demonstrated the characteristics(i.e., size, total sales, age, and knowledge intensity) of the organizations adopting each strategy.

Up to now, most studies are on interface crack problems in isotropic-isotropic dissimilar materials, but it seems to be not so much on anisotropic dissimlar materials. In this study, the stress intensity factors for an interface crack in anisotropic dissimilar materials are analysed using author's proposed extrapolation method by BEM and we have done a parametric study about material properties or shapes of crack affecting to the stress intensity factors. However, as there are not other's comparable numerical results on these anisotropic dissimilar materials to the best of author's knowledge, the reliability of the present results was proved by following two methods. The first is considering the asymptotic characteristic about stress intensity factors for an interface crack in anisotropic materials when the ansiotropic material approachs to the isotropic material. The second is considering the discontinuity of stress intensity factors between of a crack in an identical homogeneous anisotropic material and an interface crack in anisotropic dissimilar materials.

Recognizing the significance of inter-firm cooperation for firm's sustainable competitive advantage in today's business environment, this study investigates the effects of inter-firm cooperation and knowledge sharing on firm competitiveness based on 327 Korean small and medium sized enterprises. We also examines a mediating effects of knowledge sharing on the relationship between inter-firm cooperation and firm competitiveness and moderating effects of environmental factors on this relationship. The environmental factors are conceptualized by intensity of market competition and technological change. The main findings of the study are as follows: First, the paper found that inter-firm cooperation was positively associated with firm competitiveness while there was also a positive relationship between knowledge sharing and firm competitiveness. Second, it also shows that knowledge sharing partially mediated the relationship of inter-firm cooperation and firm competitiveness. Third, we also found that technological change had negative moderating effects on the relationship between inter-firm cooperation and firm competitiveness. This study suggests that understanding of inter-firm cooperation with consideration of environmental characteristics are required for better firm competitiveness.
