  • The high performance 94 GHz MMIC(Monolithic Micro-wave Integrated Circuit) single balanced mixer was designed and fabricated, using MHEMT structure based diodes and a CPW(Coplanar Waveguide) tandem coupler. A novel single-balanced structure of diode mixer is proposed in this work, where a 3-dB tandem coupler with two section of parallel-coupled line. Implemented air-bridge crossover structures achieve wide frequency operation and the fabricated mixer exhibits excellent LO-RF isolation, larger than 30 dB, in the 5 GHz bandwidth of 91-96 GHz. A good conversion loss of 7.4 dB is measured at 94 GHz. The proposed MHEMT-based diode mixer shows superior LO-RF isolation and conversion loss to those of the W-band mixers reported to date.

  • Knowledge-based exporting companies in Korea have reached a stage to develop new technological innovation and to pioneer new markets. But, developing new technologies and launching new products require an enormous sum of money for Research and Development(R&D) and there is still uncertainty in technological development and markets. Therefore, through open technological innovation, they are encouraged to actively use external technological sources and ideas. They also need to enhance the efficiency of the relatively little R&D investment. In this paper, firstly, it conducts a precedent study on the concept and influence factors of knowledge-based exporting companies and open technological innovation. Secondly, it sets a study model and estimates a regression coefficient to analyze the influence factors of open technological innovation of knowledge-based exporting companies which are using external resources on the process of innovation. Through case study and empirical analysis, we are going to find the implication of open technological innovation and prepare the way of the innovation for the knowledge-based exporting companies. According to the empirical analysis, variables such as firm size, processing degree, product life, patent registration, maintaining internal security didn't have positive effects on open innovation performance. On the other hand, research capability and market preoccupancy had positive effects. Therefore, to succeed in open innovation, knowledge-based exporting companies not only need to secure research capability through open innovation, but also need to preoccupy the market through commercialization of developed product.

  • This paper aims to explore the small and medium sized enterprises'(SMEs') technological innovation through an open innovative strategy. Researchers have identified open innovation as external search 'breadth' and 'depth'. Although an open innovation strategy is well known as an effective way for SMEs' innovation, this stream of research examines differences between pursuing breadth of external knowledge and depth of external knowledge for SEMs' innovation. The sample comprises a total of 1106 SMEs included in the Korean Innovation Survey, and logistic regression analysis and odds ratio comparison were used to evaluate the relationship between external knowledge search and innovation outcomes. The results show that both 'breadth' and 'depth' positively affect the SMEs' innovation. When SMEs are simultaneously pursuing external searching for breadth and depth, however, a negative result on innovation outcome followed because of the lack of their internal resources and capacities. Despite these contributions, we have certain limitations that can be regarded as means of future research. Even though breadth and depth are adopted to measure the way of how a firm sources the external knowledge, companies may place the different weight on each source of knowledge. And also, it is difficult to understand how the knowledge gained through external search contributes to a firm's incremental and radical innovation, respectively.

  • This research focuses on the IS development methodology as an object of innovation in an IS organization. It has two main research objectives. It was intended to understand the critical affecting factors which have an effect on the processing of each level in the dynamic and evolving innovation process. There are two levels of innovation process: initiation and implementation. It was also intended to understand the performance of IS organizational innovation. We found three main results by the LISREL analysis. First, main factors affecting initiation level of innovation are innovative tendency of IS members, communication level of IS organization, existence of champion manager, IS performance gap, executive supporting to IS, and relative advantage of IS development methodology. At the implementation level, it was understood that the existence of champion manager, executive support, and relative advantage of IS development methodology were the main factors promoting to use the innovation, and the complexity of innovation was a negative factor adopting the usage of innovation. Second, the quality of the previous level in the gradual innovation activities gives very notable affection to the continuous next level. Finally, it was found that the qualitative performance like the documentation, collaborative team approach, IS developer's awareness and ability corresponding to their task and so on was improved due to the IS organizational innovation. This research provides the standard framework for the IS organizational innovation in a structural way. In the practical aspect, it may be used as the principle for introducing and using the IS development methodology.

  • This article examines the issue of utilization of research findings from public funded research institutions (PRIs) and universities in Malaysia from the perspective of knowledge flows. Such a perspective is adapted from the literature on innovation and knowledge systems. This representation of innovation in terms of knowledge flows helps us to focus on the managerial dimensions involved in the organization of activities such as research and development (R&D). The paper reveals that there is a dismal rate of adoption of research findings generated from PRIs and universities in Malaysia. It is argued that this poor performance is a consequence of weak research management practices. A framework on the key elements of sound research management is described. The article concludes with a discussion on managerial and policy issues arising from these deficiencies and some suggestions for addressing them.

  • In this paper, we present the low voltage and high efficiency Q-band MIMIC oscillator using device-level power combined structure. The oscillator was successfully integrated by using 0.1 ${\mu}{\textrm}{m}$ GaAs PHEMTS and the CPW transmission line. We show that the highest efficiency is 19 % with an output power of 2.6 ㏈m at a frequency of 34.56 ㎓. The operating voltage of the oscillator is 2.2 V which is lower voltage than that of previously reported oscillators at Q-band. And the maximum output power of 6.7 ㏈m was obtained at a frequency of 34.56 ㎓.

  • Recently, the service innovation is getting interests among innovation researchers. After reviewing the Lancasterian approach concerning the service innovation, this paper explains concretely the innovation in the cultural industry, specifically online game industry, using Lancasterian approach. Combining Lancasterian approach and the value chains in the cultural industry systematically, we draw both implications in theory and policy. Theoretically, the innovation in the cultural industry needs interdisciplinary research due to the inclusion of diverse innovation natures-technical, content, and marketing innovation. Also this paper suggests policy makers to apply research and development(R&D) concept in the manufacturing sector to the cultural industry in which content R&D means the creation of new concepts or new development of the service.

  • Since Henry Chesbrough coined the term "open Innovation", active theoretical and empirical research has been conducted in many sectors. In Korea, private business sector took an active role in open innovation research and its adaptation. However, many public research institutes failed to follow the private sector's suit because they compete each other for limited fund from Korean government. The present research analyzed Korea Institute of Science and Technology(KIST) Open Research Program which pioneered open innovation research by sharing KIST research fund with third party entities and proposed a way to apply the KIST case to other public sectors.

  • Recent years have seen an intensified discussion in many OECD countries about the role and mission of public research in the innovation system. This discussion takes place in quite specific national contexts, but should benefit from international experience. However, whereas voluminous literatures address the changing governance methods, organizational forms and missions of universities, much less attention has been devoted to developing a common understanding of the challenges faced by non-university public research institutions. The main goals of this paper is to contribute to clarifying the nature of these challenges, outlines possible policy answers and draws some implications for Korea. In the first section, the paper uses available internationally comparable indicators to review trends in the contribution of government research institutes (GRIs) to R&D and innovation activities. In the second section, the paper identifies the current major changes in the dynamics of innovation that may call for further adjustments in the positioning, organization and steering of public research institutes. Finally, the paper outlines some strategic objectives and orientations for the reform of public research institutes as part of the broader agenda of the Korean innovation strategy.
