The rates of technological innovation and environmental change as well as market competition have recently accelerated, which makes it difficult for firms to satisfy the needs of their customers through existing product innovation or limited services. Some firms have attempted to find the solutions to this problem by conducting business model (BM) innovation. This study reviews the theoretical discussion to BM innovation and suggests propositions concerning the necessity of BM innovation and conditions of successful BM innovation. Furthermore, the study examines the applicability of the propositions and draws strategic implications by analysing the cases of two world-wide leading firms, AVL and ETAS, in the automobile R&D service sector. In particular, the study investigates how the firms with technological competence in the R&D service sector obtain market performance through BM innovation. Results of this study show that the case firms recognize the necessity of BM innovation based on product (or technology)-service fusion to effectively propose customer value and create corporate profit. Also, the firms exploit firm-specific complementary assets for successful BM innovation. This paper contributes to the literature of innovation management by promoting academic discussion concerning BM innovation in Korea and suggesting strategic implications for further development of R&D service sector and related firms in Korea.

In today's rapidly changing business environment, quality of responsiveness to customer requirements for short order cycles and on time delivery is becoming more important and considered as one of critical success factors in supply chain management. Yet despite its importance on reducing transportation cost and improving customer service, little attention has been given to the transportation planning system in Korea SI industry. In this paper, we present development of transportation planning system especially to deal with vehicle routing problem which has the goal to minimize the costs of daily transportation operation and to maximize customer delivery service. The system architecture with other enterprise application is presented and real-world constraints are well incorporated into the system by combining constraints programming and meta heuristics.

In the relationship between the shareholding ratio of National Pension Service (NPS) and the investee firm's value, this study examined the mediating effect of R&D expenditure which its increase can indirectly induce the increase of firm value, and examined the moderated mediation effect of the Stewardship Code implementation which pressures investee firms' to increase R&D expenditure and firm value. Using the Korean listed companies' data from 2016 to 2021, the analysis showed that the R&D expenditure had a partial mediation effect on the relationship between NPS's shareholding ratio and firm value. Also, the analysis showed that the NPS's Stewardship Code implementation had positive moderating effects on following relationships, one between NPS's shareholding ratio and R&D expenditure, and the other between NPS's shareholding ratio and firm value. In all, on the relationship between NPS's shareholding ratio and firm value, the R&D expenditure's mediation effect differs before and after the implementation of the stewardship code, which shows the moderated mediation effect.

In order to go digital broadcasting in Korea, it is conducted various policies in the country which be expanded network, be increased digital broadcasting hours. And broadcasting stations in the country close down analog broadcasting until 2012. Moreover IPTV is a method of delivering broadcast television and on-demand, rich media content that uses an IP(Internet protocol network) as the medium. And an IP is regarded as a very favorable approach for the future "Medium for Digital TV". However It is not easy to replace the entire digital infrastructure. And there are some problems in the digital infrastructure for Digital TV(i.e. channel zapping delay). Moreover user require service. IPMG is to solve these problems. IPMG is digital converter that allows receive and transmit signal by using many kinds of medium for Digital TV. Moreover IPMG provides users a Network PVR service. In this paper we developing, manufacturing IPMG and analyze its performance.

This study was conducted to estimate phenotypic and genetic parameters of body condition score (BCS) and reproductive traits in Hanwoo cows. DFREML procedures were applied to obtain variance-covariance components and heritability estimates with single or two-trait models. Estimates of phenotypic correlations of BCS at service with BCS at calving was 0.16 and 0.26 with calving interval, 0.08 with gestation length, and 0.06 with number of services per conception, respectively. Estimates of phenotypic correlation of BCS at calving was 0.10 with calving interval, 0.13 with gestation length, and 0.10 with number of services per conception, respectively. Estimates of phenotypic correlation were low and negative, -0.11 between calving interval and gestation length and -0.13 between gestation length and number of services per conception. Estimates of direct genetic correlation were -0.06, between BCS at service and BCS at calving, 0.37 between BCS at service and BCS at weaning, and -0.18 between BCS at calving and BCS at weaning. Estimates of direct genetic correlation of days from calving to the 1st service were 0.17 with number of services per conception and -0.21 with BCS at service. Estimates of direct genetic correlation for BCS at calving were -0.02 with number of services per conception and -0.08 with BCS at service. Estimates of direct genetic correlation for BCS at weaning were 0.02 with number of services per conception and -0.07 with BCS at service. Estimates of direct heritability from single trait analyses were 0.13 for BCS at service, 0.20 for BCS at calving, 0.02 for BCS at weaning, and 0.20 for number of service per conception, respectively. Estimates of direct heritability were 0.20 for birth weight and 0.10 for weaning weight.

Purpose - Major countries in the world continue to grow up without employment by the economy opening, more investment in foreign countries and technical innovation. Nevertheless, SMEs have job creation continuously. As this result, support for SMEs that is the source of job creation has increased attention. However, previous research between SMEs and job-creating is limited to the job creation effect of comparing with large companies, and R&D investment effect including government support. Also, many research provides the different result of correlation with technology innovation and job creation. Therefore, previous research has insufficient to explain job creation by which in the technology commercialization stage and the job-specific workforce. Research design, data, and Methodology - This study investigated the impact of customized R&D support upon job creation by using questionnaires of SMEs R&D service of K-Institution from 2009 to 2013. In detail, we analyzed the relationship between the technology commercialization stage and the usefulness of customized R&D support. Also, we added the analyzed the relationship between the usefulness of customized R&D support and the job-specific workforce. Results - Research result, Job creation had a significant relation to the usefulness of customized R&D support in product design stage and mass production stage. Also, R&D worker and production worker correlated with the usefulness of customized R&D support. These results indicate the importance of hiring R&D workers and production workers at the higher technology readiness. Conclusions -Therefore, this study suggests some implications for the government's SMEs support policy and the solve employment problems such as youth unemployment.

This study is to suggest legislation and criteria for public service drones for disaster safety in order to enhance the research and development of the drones by helping setting right direction of the R&D. Many foreign governments are now conducting research and development on using drones as public service for disaster safety. Although there are also some efforts to using drones for public service in Korea, domestic laws and performance criteria for the drones for the purpose have not prepared yet. To set a right direction of the R&D, the laws and criteria shall be legislated and established immediately and then we can enhance the efforts to develop related technology for the drone. So this study proposed a performance criteria to fit various circumstances and situations by analyzing the aviation law in overseas. We hope this study can help R&D on the public service drones for disaster safety.
