In this study, we fabricated the DAMLs using surface micromachining technology as well a low loss coupler for the millimeter-wave band applications using these DAMLs. The structure of DAML is that a signal line is supported on ground plane by dielectric posts. Therefore it has advantages about the loss characteristic and the stable structure. The other advantage of the DAML process is a simple and convenient technique using 4 mask steps, even if it has a micromachining technology. The lowest loss of the fabricated DAML was obtained 2.2 dB/cm at 110 GHz. To obtain the low loss characteristic, couplers were designed and fabricated by using DAMLs. The fabricated ring hybrid coupler has the coupling of 3.58 dB and the thru of 3.31 dB at 60 GHz. We can also obtain the coupling of 3.42 dB, the thru of 3.82 dB from fabricated branch line coupler at 60 GHz.

The purpose of this study was to develop an empirically-based inventory of organizational innovativeness of social welfare organizations. Review of literature on innovation research and panel study resulted thirty-seven(37) pre-items for measuring organizational innovativeness. An exploratory factor analysis of the pre-items drawn from the first survey data of 178 social workers revealed seven(7)-factor structure of 31 items. The factors included leadership innovation, team work innovation, task innovation, program development innovation, program technology innovation, idea innovation. A confirmatory factor analysis using data from the second survey of 409 social workers also indicated relevance of seven(7) factor structure of the inventory. Further these seven factors showed positive and significant correlations with measures for innovation culture indicating the inventory had the criterion-related validity. Although additional work remains in methodological issues, the results presented in this paper have shown that this inventory of organizational innovativeness can be an useful tool for assessing innovativeness of social welfare organizations.

This research works has newly proposed ideation method for development of innovative product design by using four design thinking framework in the aesthetic issue, material issue, function & structure issue which are usually called three major design issues. The four design thinking framework is consisted of eliminate, reduce, raise and create. This research also analyzed 232 innovation products in order to verify the proposed ideation method. The main outputs of this research are as follows; first, the ideation method which was newly developed in this research can help to create new ideas for innovation product design. Second, 41% existed innovation product designs were developed based on the ideation in the 'function & structure' issue. Three, 74% existed innovation product designs were developed based on the 'raise & create' issue rather than 'eliminate & reduce' issue. The results of this research can help a designer who wants create new innovation product.

The standards of valuation for technology and business are announced on December of 2000, by a Committee for the Standards of Valuation for Technology and Business led by the author. This is a first effort to set up a social standards of valuation in Korea. Hence, this paper will chase the background philosophy and structure of the standards, and its relationship with international and american standards. The standards of valuation is a product of social agreement, not a bundle of knowledge of professional experts.

Managing of local government public service is innovation strategy of local government public service using choice and competition principle. Managing strategy of local government public service is new paradigm for innovating public service and role structure of government. It is important to understand properly substance and characteristics of local government public service Accordingly, the purpose of this study understand substance and characteristics of local government public service and describe strategic driving plan of managing local government public service in the future.

This paper intends to clear up the conte31t of the interdisciplinary nature of individual researches. First, the interdisciplinary character of individual research was analyzed. Approximately 40% of individual research projects supported by Korea Science and Engineering Foundation has the interdisciplinary nature. Second, there are close connections among research fields in individual research projects. Every research field needs the inflow of knowledge from other fields and supports other research fields as well. The interrelation among various research fields indicates the importance of the balanced development in all science and engineering fields.

This article is concerned with the importance of organisation management and its characteristics in business performance in SMEs, and tested by four main aspects: managerial strategies, organisational structure, leader behaviour, and R&D activities. These relationships were tested with questionnaire data from a random sample of 87 firms. Results from simple statistics on each issue showed that SMEs have focused on the corporate growth and management goals, the democratic leadership, decentralisation in organisational structure, and the technology development plans. Results from correlation analyses not only found significant relationships between managerial strategy and R&D activities but also showed differences in R&D activities according to structural status or leadership style, respectively.

According to "structure-conduct-performance" paradigm in IO, market structure (concentration) determines conduct (R&D investments), and conduct yields market performance (ratio of price to marginal cost). Previous empirical studies on Schumpeter Mark I, II assumed that the explanatory variable (market structure) and the disturbance are uncorrelated in the R&D equation. In this situation, Ordinary Least Squares (OLS) estimates of the structural parameters are inconsistent, because the endogeneous variables (R&D and market structure) can be determined simultaneously. So, in this study, full information (or system methods) estimation is used to test Schumpeter hypothesis since joint estimation can as well bring efficiency gains in the seemingly uncorrelated regressions (SUR) setting.

This study aims to analyze the network structure of technological innovation resources in SMEs, especially manufacturing firms, and reveal the differences between innovative and non-innovative firms. The study first analyzes connection centrality, flow-mediated centrality, and power centrality for all firms, and derives structural equivalence through CONCOR analysis. Then, the network structure of innovative and non-innovative firms was compared and analyzed according to innovation performance and creation. The results show that entrepreneurship and corporate innovation strategy have a significant impact on the analysis of technological innovation resources of all firms. According to the CONCOR analysis, the innovation resources of SMEs are organized into seven clusters, which can be defined as intrinsic product innovation resources, competitive advantage promotion resources, cooperative activities resources, information system resources, and innovation protection resources. The network analysis of innovative and non-innovative firms showed that innovative firms focused on enhancing competitiveness and improving quality, while non-innovative firms tended to focus more on existing products and customers. In addition, innovative firms had eight clusters, while non-innovative firms had six clusters, suggesting that innovative firms utilize resources diversely to pursue structural change and new value creation, while non-innovative firms operate technological innovation resources in a more stable form. This study emphasizes the importance of entrepreneurship and corporate innovation strategy in SMEs' technological innovation, and suggests that strong internal efforts are needed to increase innovativeness. These findings have important implications for strategy formulation and policy development for technological innovation in SMEs.
