This paper aims at discussing the evolution of innovation theory from the beginning of the last century to present. Innovation theory has begun by Joseph Schumpeter in the beginning of the last century and his theory had not attained much attention compared to the mainstream economic theory. In the 1960s, some neo-classical economists analyzed the effect of technological change on economic growth and emphasized the role of demand in innovation process. However, in the beginning of the 1970s, Schumpeter's innovation theory, which emphasized the role of innovation and entrepreneurship in economic and social development, attained enormous attention by many liberal economists. They were called neo-Schumpeterians as they followed the theories and ideas of Schumpeter. In the middle of the 1980s, neo-Schumpeterians identified the concept of national innovation system(NIS), which is the total mobilization system of innovation resources for generating, appropriating and diffusing technological innovations. Soon this theory diffused very quickly at regional and sectoral level. As a result, there have been very active empirical studies on innovation systems in the world. Since the beginning of the 2000s the transition study have been actively carried out mainly in European countries. This study emphasizes the transition of existing innovation systems into more sustainable ones. In Korea we need to activate transition study, because there have been only few studies in this new theory.

Recently, the importance of technological innovation has increased for securing competitiveness and for the survival of companies. On the other hand, obstacles that enterprises face during the course of technological innovation have diversified. Through prior studies, various innovation sources and government support systems are considered important factors in resolving these obstacles as well as securing technological innovation and competitiveness. However, these studies face criticism concerning various relationships between the influencing factors and the use of simple causal models. In this study, the effects on performance were analyzed based on a structural equation model. For analysis, 1,251 observed values were collected from the "2014 Korean Innovation Survey: Manufacturing Sector". Results found that obstacles to technological innovation in terms of fund, capacity and market promote the use of innovation sources and government support programs. On the other hand, various innovation sources and government support systems utilized by corporations have positively influenced technological innovation performance. As expected, among these obstacles, financial limitation had the greatest negative effect on innovation.

This study aims to identify various service innovation patterns in the service industry and understand the main differences among them. We attempt to create a new typology of service innovation by analyzing its patterns based on the four major dimensions of service innovation (i.e., service concept, service delivery, customer interaction, and technology). We then investigate whether firms pursuing different service innovation patterns significantly differ from one another in terms of their performance (high and low performance). Based on empirical data collected from 198 Korean firms in the knowledge-intensive business service sector, four major clusters composed of different service innovation dimensions are identified. These four clusters can be interpreted as specific service innovation patterns, including "technology based high customer interaction," "high technology based high service delivery," "service delivery and high customer interaction-integrated," and "strongly balanced" innovators. High firm performance does not depend on the individual service innovation dimension but on the specific configurations of such service dimensions. Customer interaction also has an important role in achieving innovation success and improving firm performance, while technology has a key role in enhancing firm performance. This study sheds new light on service innovation research by developing a new typology of service innovation, identifying four major clusters as service innovation patterns, and exploring the relationship between service innovation patterns and firm performance.

This paper aims to present a polynomial approach to the steady-state optimal filtering for delayed systems. The design of the steady-state filter involves solving one polynomial equation and one spectral factorization. The key problem in this paper is the derivation of spectral factorization for systems with delayed measurement, which is more difficult than the standard systems without delays. To get the spectral factorization, we apply the reorganized innovation approach. The calculation of spectral factorization comes down to two Riccati equations with the same dimension as the original systems.

This study empirically examined the differences in degrees of product or process innovations according to the activation forms of all knowledge management (KM) processes (i.e., socialization, internalization, externalization, and combination), which are influenced by the usage patterns of management control systems (MCS)(i.e., interactive and diagnostic usage patterns). We empirically investigated and identified the links among usage patterns of MCS, the activation forms of KM processes, and the kinds of innovation promoted. Under high competitive conditions, it was found that the interactive usage of MCS is relatively more preferred and enhanced. However, when environmental uncertainty is high, it was shown that the diagnostic use of MCS is more emphasized. Thus, it is evident that the use patterns of MCS are determined by environmental conditions. From the results of this study, it was suggested that under high interactive use of MCS, the activation of socialization and internalization is more enhanced than the facilitation of externalization. It was also observed that when both interactive and diagnostic usage of MCS are high, KM processes are more activated and strengthened. The results indicated that under high activation of KM processes, product innovation as well as process innovation are more frequently occurred. Finally, the results of this study suggested that according to the levels of innovation openness, major innovations are more frequently occurred and promoted than minor innovations.

As the advent of the Fourth Industrial Revolution and Information Age, companies are in the state of infinite competition due to the rapidly changing technological environment and fierce competition. In this situation companies are making efforts to gain the competitive advantage by introducing information systems. Supply Chain Management (SCM) is considered a method to gain a competitive edge in rapid change. In fact, companies that already have introduced the SCM system are achieving company renovation with positive effects such as increase of sales stock reduction on-time delivery cost reduction and improved efficiency. This study was started to investigate the resistance that occurs in introducing the SCM system for small and medium-sized manufacturing industries that have not yet introduced the SCM system despite the importance of the SCM system, and to check the effect on the intention of the introduction. As the result of this study, the first is that the company has the higher technological innovation, the more positive the effect on Relative advantage Compatibility Perceived risk, Complexity. Second, The compatibility of the SCM system was rejected in innovation resistance, but it is adopted with the highest impact in the introduction intention. In addition, the mediating effect of innovation resistance was also rejected, confirming that if the SCM system is compatible for the company, it doesn't affect the resistance and is the biggest factor to consider in the introduction of the SCM system. Third, the perceived risk of the SCM system doesn't directly affect the intention to introduce, but has an indirect effect when mediation innovation resistance.

Previous researches on technological innovation of SMEs have several limitations such as lack of study for industrial cluster system and entrepreneurship in SMEs, and ignoring role of RandD capability. So, this study suggested empirically a new model to SMEs. Major results are as follows. Firstly, system of industry and production had a significant and positive effect on entrepreneurship. Secondly, entrepreneurship had a significant and positive effect on technological innovation. Thirdly, system of science and technology had positive and significant effects on RandD capability and technological innovation. Fourthly, RandD capability had a positive and significant effect on technological innovation. Fifthly, business support system was not significantly related to entrepreneurship, RandD capability and technological innovation. Research results revealed that industrial cluster system(system of industry and production, system of science and technology), entrepreneurship and RandD capability were important for improvement of technological innovation performance in SMEs.

To provide a fundamental understanding on the inherent relationship between IT capabilities and sustainable firm heterogeneity, we investigate the dual roles that institutional pressures play, namely, as antecedents of IT capabilities and as moderator of the relationship between IT capabilities and IT innovation success, where IT innovation success plays a mediating role between IT capabilities and firm performance. The structural model was tested, and the results of the PLS analysis provided general support for the proposed hypotheses. IT capabilities had an indirect effect mediated by IT innovation success on firm performance. With IT activities assumed to be embedded in the institutional context, the dual roles of institutional pressures are verified. This study contributes to the literature on IT capabilities by considering both the determining role of institutional pressures on IT capabilities and the institutional context of the chain that connects IT capabilities to firm performance. The results suggest that a firm not only manages various institutional pressures to foster its IT capabilities but also adapts to different contexts with a certain level of institutional pressures to facilitate its IT capabilities and outperform its competitors, which could be sustained through IT innovation success.

In this paper, a Efficient method for the mixed image separation is presented using independent component analysis and the new fast expectation-maximization(EM) algorithm. In general, the independent component analysis (ICA) is one of the widely used statistical signal processing scheme in various applications. However, it has been known that ICA does not establish good performance in source separation by itself. So, Innovation process which is one of the methods that were employed in image separation using ICA, which produces improved the mixed image separation. Unfortunately, the innovation process needs long processing time compared with ICA or EM. Thus, in order to overcome this limitation, we proposed new method which combined ICA with the New fast EM algorithm instead of using the innovation process. Proposed method improves the performance and reduces the total processing time for the Image separation. We compared our proposed method with ICA combined with innovation process. The experimental results show the effectiveness of the proposed method by applying it to image separation problems.
